Q: Unexpected distribution of columns when using using MPI_Scatter with MPI_Type_vector I am trying to divide columns of a 2D matrix among N process with MPI. For template I used the example on MPI_Scatter - sending columns of 2D array.
My code:
//HEADERS
    char** board_initialize(int n, int m)
    {
        int k, l;

        char* bd = (char*)malloc(sizeof(char) * n * m);
        char** b = (char**)malloc(sizeof(char*) * n);
        for (k = 0; k < n; k++)
            b[k] = &bd[k * m];

        for (k = 0; k < n; k++)
            for (l = 0; l < m; l++)
                b[k][l] = rand() < 0.25 * RAND_MAX;

        return b;
    }

    void board_print(char** b, int n, int m)
    {
        int k, l;

    //  system("@cls||clear");
        for (k = 0; k < n; k++)
        {
            for (l = 0; l < m; l++)
                printf("%d", b[k][l]);
            printf("\n");
        }
        printf("\n");
    }

    int main(int argc, char* argv[])
    {
        int N = 10;
        int i, j;

        char * boardptr = NULL;                 // ptr to board
        char ** board;                          // board, 2D matrix, contignous memory allocation!

        int procs, myid;
        int mycols;
        char ** myboard;                        // part of board that belongs to a process

        MPI_Init(&argc, &argv);                 // initiailzation

        MPI_Comm_rank(MPI_COMM_WORLD, &myid);   // process ID
        MPI_Comm_size(MPI_COMM_WORLD, &procs);  // number of processes

        // initialize global board
        if (myid == 0)
        {
            srand(1573949136);
            board = board_initialize(N, N);
            boardptr = *board;
            board_print(board, N, N);
        }
        // divide work
        mycols = N / procs;

        // initialize my structures
        myboard = board_initialize(N,mycols);

        MPI_Datatype column_not_resized, column_resized;
        MPI_Type_vector(N, 1, N, MPI_CHAR, &column_not_resized);
        MPI_Type_commit(&column_not_resized);
        MPI_Type_create_resized(column_not_resized, 0, 1*sizeof(char), &column_resized);
        MPI_Type_commit(&column_resized);

        // scatter initial matrix
        MPI_Scatter(boardptr, mycols, column_resized, *myboard, mycols, column_resized, 0, MPI_COMM_WORLD);
        MPI_Barrier(MPI_COMM_WORLD);

        board_print(myboard, N, mycols);

        MPI_Finalize();         // finalize MPI

        return 0;
    }

The whole board looks like:
0000010010
0100000000
0000101100
0101000010
1000000100
0000010010
0000001110
0110000100
0000100000
0100010010

And if I use 2 process I expect that each proces would get half (first process columns 1-5 and second proces columns 6-10). But if I print myboard of both process I get some strange results:
proc0:       proc1:
0 0 0 0 0    1 0 0 1 0
0 0 1 0 0    0 0 0 1 1
0 1 0 0 0    0 0 0 0 0
0 1 0 0 0    0 1 0 1 0
0 0 0 0 1    0 1 1 0 0
0 1 1 0 0    0 0 1 0 0
0 1 0 1 0    0 0 0 1 0
0 0 0 0 1    0 0 1 0 0
1 0 0 0 0    0 0 1 0 0
0 1 0 0 0    0 1 0 0 0

It's probably some silly mistake, but I just can't seem to find it. Any help would be really appreciated. <3
Note: the output of proc1 is probably just some garbage, because I get different output on every run.

A: You forgot to differentiate between send and receive types, i.e., the parameters of MPI_Type_vector will depend on the appropriate type. You need to do something as follows:
MPI_Datatype acol, acoltype, bcol, bcoltype;
if (myid == 0) {
    MPI_Type_vector(N, 1, N, MPI_CHAR, &acol);
    MPI_Type_commit(&acol);
    MPI_Type_create_resized(acol, 0, 1*sizeof(char), &acoltype);
}
MPI_Type_vector(N, 1, mycols, MPI_CHAR, &bcol);
MPI_Type_commit(&bcol);
MPI_Type_create_resized(bcol, 0, 1*sizeof(char), &bcoltype);
MPI_Type_commit(&bcoltype);
MPI_Scatter (boardptr, mycols, acoltype, *myboard, mycols, bcoltype, 0, MPI_COMM_WORLD);

From the sender point of view you want to create N blocks (i.e., N rows), with a size of 1 and a stride of N (i.e., N columns). Hence:
MPI_Type_vector(N, 1, N, MPI_CHAR, &acol);

From the receiver point of view you want to create N blocks (i.e., N rows), with a size of 1 and a stride of mycols  (i.e., mycols columns). Hence:
MPI_Type_vector(N, 1, mycols, MPI_CHAR, &bcol);

Side note you do need the MPI_Barrier after the MPI_Scatter since the latter is a blocking call already.
The final code would look like the following:
#include <stdio.h>
#include <stdlib.h>
#include <mpi.h>

    char** board_initialize(int n, int m)
    {
        int k, l;

        char* bd = (char*)malloc(sizeof(char) * n * m);
        char** b = (char**)malloc(sizeof(char*) * n);
        for (k = 0; k < n; k++)
            b[k] = &bd[k * m];

        for (k = 0; k < n; k++)
            for (l = 0; l < m; l++)
                b[k][l] = rand() < 0.25 * RAND_MAX;

        return b;
    }

    void board_print(char** b, int n, int m)
    {
        int k, l;

    //  system("@cls||clear");
        for (k = 0; k < n; k++)
        {
            for (l = 0; l < m; l++)
                printf("%d", b[k][l]);
            printf("\n");
        }
        printf("\n");
    }

   int main(int argc, char* argv[])
    {
        int N = 10;
        int i, j;

        char * boardptr = NULL;                 // ptr to board
        char ** board;                          // board, 2D matrix, contignous memory allocation!

        int procs, myid;
        int mycols;
        char ** myboard;                        // part of board that belongs to a process

        MPI_Init(&argc, &argv);                 // initiailzation

        MPI_Comm_rank(MPI_COMM_WORLD, &myid);   // process ID
        MPI_Comm_size(MPI_COMM_WORLD, &procs);  // number of processes

        // initialize global board
        if (myid == 0)
        {
            srand(1573949136);
            board = board_initialize(N, N);
            boardptr = *board;
            board_print(board, N, N);
        }
        // divide work
        mycols = N / procs;

        // initialize my structures
        myboard = board_initialize(N,mycols);
    MPI_Datatype acol, acoltype, bcol, bcoltype;

    if (myid == 0) {
            MPI_Type_vector(N,
                1,
                N,
                MPI_CHAR,
                &acol);
                MPI_Type_commit(&acol);
            MPI_Type_create_resized(acol, 0, 1*sizeof(char), &acoltype);
    }
    MPI_Type_vector(N,
               1,
               mycols,
               MPI_CHAR,
               &bcol);

    MPI_Type_commit(&bcol);
    MPI_Type_create_resized(bcol, 0, 1*sizeof(char), &bcoltype);
    MPI_Type_commit(&bcoltype);

    MPI_Scatter (boardptr, mycols, acoltype, *myboard, mycols, bcoltype, 0, MPI_COMM_WORLD);
        board_print(myboard, N, mycols);

        MPI_Finalize();         // finalize MPI

        return 0;
    }

Alternatively, and much easier in IMO is to divide by rows instead of columns the code would look like the following:
int myrows = N / procs;
myboard = board_initialize(myrows, N);
MPI_Scatter (boardptr, myrows, MPI_CHAR, *myboard, myrows, MPI_CHAR, 0, MPI_COMM_WORLD);
board_print(myboard, myrows, N);

Singer slapped at the back of her neck and shifted to a more comfortable position while she waited for the rest of her group to catch up. She'd been to just about every terraformed planet in the system, and no matter what color the sky, plants, or critters happened to be, they all had one thing in common: bugs.
If scientists could figure out how to turn a dead rock into a habitable planet, why couldn't they do it without the bugs? She let her mind wander while her eyes tracked back and forth across the red horizon. Every few minutes she slapped reflexively at whatever bug had stopped by for a snack.
"Singer! Damn it Singer, where the hell are you?" The roar of their expedition leader bounced around the trees.
"Ten meters ahead, Freberg!" she yelled back, rolling her eyes. Scouts scouted ahead, that was the definition of the job, but Freberg got nervous if he lost sight of her for more than a second or two.
She heard the group before she saw them. They moved slowly around the massive trunks of trees that were an odd cross of pine and oak. The leaves that covered the floor of the forest looked like they should rustle just like the ones back on Earth, but the oddly sibilant noise they made as the group passed over them added to the hostile feel of the place.
She wondered, briefly, if the color of his face was an effect of the red sky and foliage all around them. She glanced at the drawn faces of the other four expedition members and opted against deliberately aggravating their EL.
"Not far, maybe one more hour if we move at a good pace." Her gray eyes swept over the horizon again.
"Fine. Can we just stay together? At least until we know the situation at the colony." The hand that pulled a cloth over his sweating face was shaking slightly.
Freberg rubbed the back of his neck and nodded. They all had headaches—the shades of red covering the planet had that effect. The colonists had goggles that provided some protection, but their expedition hadn't been issued any.
Forty-five minutes later they passed the outbuildings of the colony and what little chatting there was fell silent.
The buildings were intact; there were no signs of a hostile attack either by a rival faction of colonists or anything else. It was clear that the forest was beginning to reclaim the area cleared by the colonists, but everything else remained pristine.
The group split up, leaving her with Freberg.
"So Freberg, what did you say the name of this colony is?" she asked, and grinned when fumbled a data disk out of his pocket.
"Hmmm…that's interesting," he frowned at the display.
"What is?" She looked back to where he'd stopped walking.
This post is the beginning of what I'm calling "Lucky Sevens." The idea is that I'm going to try to write a short story every day that is exactly 700 words. I'm hoping that this will help me take my writing more seriously, and maybe jump-start my brain on a novel idea...which I'm very short on at the moment! If you'd like to join in, just leave a link to your Lucky Seven in my comments and I'll be happy to pop over and read it!
Exactly 700? Now that IS a challenge! But I have heard that writing a bunch of short stories is a great way to jump start a writer's brain. I think there's a Ray Bradbury quote about writing a story every week for a year gets all the "junk" out of your system.
Yeah and I have a LOT of junk to purge! LOL I like the challenge of hitting an exact word count...makes me read and re-read to get it right and tight.
Every day? You are ambitious. But I think you ought to go for it. Your fiction feels natural and believable and the dialogue is not at all forced. I wish you well!


What is Contact Dermatitis of the Foot?
Contact dermatitis of the foot is an inflammation of the skin in response to an irritant.
When the skin of the foot comes into contact with the substance, an allergic response is initiated.
Symptoms, including redness, itchiness, and small blisters, usually occur within 24 hours of exposure to the irritant.
The symptoms should be evaluated by a foot and ankle surgeon for proper diagnosis and treatment.

Astatine's Periodic Table
Group 16 Group 17 Group 18
Like the other halogens, astatine is a nonmetal, although it shows more metallic character in its chemistry than the others. Astatine and the elements on either side of it, polonium and radon, have no stable isotopes. Too little astatine has ever been present in one place for anyone to actually see it – in fact, since astatine's boiling point is just 337 °C, any visible quantity of it would be instantly vaporized by the energy released by its rapid radioactive decay.
Discovery of Astatine
Author: Dr. Doug Stewart
The first periodic table, produced by Russian chemist Dmitri Mendeleev in 1869, had a space directly underneath iodine. The element to fill this space became known as eka-iodine. This alerted scientists to the possibility that if they looked, they could find the element that would fit into this space.
Many tried to find the new element in nature, but without success.
71 years after Mendeleev published his first periodic table, the element had still not been found, but was instead synthesized in the laboratory using one of the earliest particle accelerators.
Astatine was first produced in 1940 by Dale R. Coson, Kenneth Ross Mackenzie and Emilio Segrè at the University of California, Berkeley.
Segrè, working with Carlo Perrier, had previously synthesized technetium in 1937.(2), (3)
Astatine was made by bombarding bismuth-209 with alpha particles in a cyclotron (particle accelerator) to produce, after emission of two neutrons, astatine-211. The scientists found that the isotope they created was radioactive, so they named the element using the Greek 'astatos' meaning unstable.
It is now known that there are no stable astatine isotopes – the longest lived isotope, astatine-210, has a half-life of 8.3 hours. (3)
Three years later, astatine was found in nature by Berta Karlik and Traude Bernert as an intermediate in radioactive decay chains. Traces of the element appear naturally in uranium and thorium minerals as a decay product.
At any given time, about 25 grams of naturally occurring astatine exists on our planet. (3), (4)
Highly radioactive
Astatine is highly radioactive and is only available in tiny quantities. Its properties are inferred from its position in the periodic table and by studying its chemistry in extremely dilute solutions.
Like the other halogens, astatine would be expected to form salts with metals such as sodium. Astatine can also react with hydrogen to form hydrogen astatide, which when dissolved in water, forms hydroastatic acid.
Astatine is the least chemically reactive of the halogens and exhibits the most metallic properties of the halogen group.
Uses of Astatine
Astatine-211 is sometimes used as a radioactive tracer and in cancer treatment.
Like iodine, it is known to accumulate in the thyroid gland.
Abundance arth's crust: About 25 grams exists in Earth's crust at any given time.
Abundance solar system: negligible
Source: Astatine is produced synthetically by bombarding bismuth with alpha particles. It can be obtained naturally from thorium or uranium decay.
Isotopes: More than 30 isotopes of astatine have been identified. All are very short-lived; astatine-210 has the longest half-life of 8 hours 10 minutes.

This website was very useful but there is no pricing for my element.
It has no pricing because it is not for sale anywhere. Also, it would be a waste of money considering it is highly deadly, being radioactive, and it also decays in 8 hours.

Synthetic Bio Platform Finds Potential Superbug Antibiotic
By Alan, on January 22nd, 2014
Scanning electron micrograph of Saccharomonospora bacteria (National Library of Medicine)
Researchers at University of California in San Diego created a process for cloning synthetic gene clusters from marine bacteria that generate molecules with therapeutic potential, and produced an antibiotic candidate to treat previously drug-resistant infections. The team led by UC-San Diego oceanography and pharmacy professor Bradley Moore, published its findings yesterday online in the journal Proceedings of the National Academy of Sciences (paid subscription required).
The university's technology transfer office applied for patents on both the cloning process and the antibiotic generated by that process, with each disclosure listing Moore as the inventor.
The research team — with colleagues from UC-San Diego, JNC Corporation in Japan, and University of British Columbia in Canada — sought a method for capturing more of the specialized compounds that microorganisms can produce, but under lab conditions are often difficult to create. The problem is particularly acute, say the researchers, with ocean microorganisms that are difficult to grow or express all of their capabilities in the lab.
Moore and colleagues used a technique known as transformation-associated recombination that can isolate clusters of genes from complex genomes. The researchers adapted recombined gene clusters from yeast, by working with high-throughput sequencing to clone gene clusters from the marine Saccharomonospora bacteria.
These synthesized gene clusters express a lipopeptide — a combination of lipid and peptide — with antibiotic properties the researchers call taromycin A. This antibiotic is chemically similar to the FDA-approved antibiotic daptomycin, marketed as Cubicin by Cubist Pharmaceuticals, a treatment for complicated Staphylococcus aureus infections including those from methicillin-resistant or MRSA bacteria.
The researchers believe the technology can open-up previously difficult to access biological pathways to generate new drug candidates. Moore says in a university statement, "the new synthetic biology technology we developed – which resulted in the discovery of a new antibiotic from a marine bacterium – is just the tip of the iceberg in terms of our ability to modernize the natural product drug discovery platform."

Here are some pics of Jaxies new kennel and I was curious how do I make her love her kennel and enjoy her time in the kennel?
Is their a certain time to put her in the kennel and let her out?
Pic of Jaxie enjoying her bone!!
Pic of Jaxies best friend, Mocha.
Well, my first question would be how much socialization your doggy gets. If she spends most of her days in her kennel by herself, I'd say it's not that she hates her kennel, it's that she hates being alone.
My suggestion would be to start with the dog house. It looks like you put a lot of effort into that, which I commend you for, but it's actually not a very ideal house. Dog houses should be as small as possible so that they can trap your dog's body heat to keep him warm. The door should also be as small as possible so that the body heat stays in and cold air can't come in.
And lastly, exercise. Wear her out so that her kennel is just a resting spot rather than a place to be trapped with a bunch of energy. Take her for a long walk (or run if shes up to it) or make up a spring pole or flirt pole for her to take her energy out on.
I don't know how much cold weather you get in west Texas (somehow, I think "not a lot" ) so I'm not so much worried about the size of the house, but rather that the flat roof could provide an enterprising dog a step up, to hop over the kennel fencing, and right over that six foot privacy fence the kennel is up against ~ and out into a big scary world that won't appreciate how lovely she is, or how much she needs to be protected.
How much time do you plan for her to spend in her kennel daily? It looks like you have a good start, and lots of fun and yummy doggy things are a good way to keep her chewing and entertained while you're away. The wading pool looks to be a really nice touch, BTW. Does she like it much?
I see your kennel is set up on grass ~ does your dog not dig?
I can't read it well ~ what does the sign on the kennel door say?
BTW, Mocha with that HUGE bone is absolutely adorable. . .
We built the kennel because she was chewing on the side of the house no matter how many toys and treats we had outside. She is only in the Kennel when no one is home and at night. She's not in there all that much. She just cries the whole time.
It's hard to tell from the pictures but the dog house isn't against the fence. We scooted it away for that reason. She hardly ever uses the dog house anyway. She mainly sleeps in a chair that is usually in the kennel.
She used to dig a little but since we got the pool she hasn't even tried. She LOVES it. We can't go outside without getting wet.
The sign is just a No Trespassing sign that was already on the gate. We are looking into getting an I Love My Pitbull sign or something just as cute.
thats exactly what i was cracking up at.
That is a nice kennel though, good size for her i tlooks like.
is she chewing holes in the kennel too, looks like some hoes in the fencing, along the bottom?
The first couple of times we put her in she chewed on the fence so it is stretched out. We are thinking about putting two feet of cattle fencing around the bottom. It's a lot thicker so she can't do that.
yeah, that bone is bigger than Mocha. But she tries to chew on it every time Jaxie's not.
Ditto. (Or in your bed ) Especially in Texas. Imagine sleeping outside at night with a bazillion masquitos biting you all night and a masquito breeding ground (the pool) within inches from where you sleep. And the heat outside is way too unbearable to be stuck out in it ALL day while no one is home. While it may not get as cold as some parts of the country, it can still get too cold for a Pit Bull to be left outside during the winter. There's just too much risk in leaving a dog, even in a kennel, outside alone during the day or night. It's like leaving a toddler alone, it's asking for trouble. Pit Bulls are easy to steal or she could easily try to climb out of the kennel and get her collar caught on the fence and hang herself.
Chopper is used to being able to be in his kennel during the day, he much prefers it to being in a crate..and now we have new hours at work where I am gone longer during the day, but have an extra day off. He doesn't bark much at all unless there are strangers around, so the neighbors don't mind...even the non-dog-loving neighbor likes that. Usually, Chopper is sleeping at night when we are, anyway.
So, to keep a dog outside in hot weather, we were thinking about some type of big fan. A roof, definitely to protect from rain and sun, like we have now. Maybe some type of water misting system that goes off once in awhile?
I know lots of you don't agree with keeping dogs outside, but some people are going to do it, so may as well give them some good ideas to keep the dogs as safe and comfortable as possible.
I have yet to purchase a crate for jaxie. i just dont think that she would like it being cooped up in a crate at night. At least in her kennel she can walk around and has some room to play. As for the mesquitos, i change the water about every other day and have not noticed alot of mesquitos yet. The pool is for her to cool off in when it is hot outside. I would not mind her in the house sometimes except the shedding. Should a buy a crate and put her in that at night?
I put a baby pool like that in our yard for the dogs...but not in the kennel...i think Chopper would chew on it. If I change the water every 2-3 days, we don't get mosquitoes either. Plus, I like to keep moving it so it won't kill the grass. I give them their baths in there, too.
You can get sun shade mesh that goes over the top of the kennel. I like kennels to be topped, (w/wire as well as a sunscreen). Once a dog learns to climb wire, it's pretty easy for them to get out.

New York City Principal uses racial slurs, fires teachers
On Behalf of Kessler Matura P.C. | Jul 13, 2013 | Workplace Discrimination
A Queens high school principal has come under fire recently due to allegedly using racial slurs about two African-American teachers and then firing them without just cause.
The school is in the Elmhurst area. The principal allegedly employed racial stereotypical slurs referring to facial characteristics of African Americans' hair, lips and other physical characteristics. An affidavit by the vice principal alleges the principal compared the teachers' features to those of a gorilla.
The Vice Principal also told reporters that the principal attempted to fire him after he filed the affidavit. The principal justified letting the teachers go due to poor teaching evaluations. One instructor insisted he had a clean teaching record and satisfactory evaluations from the previous administrator. When the new person came along, he felt she had targeted him from the start.
The second teacher stated she would change professions, disappointed in the way the system had treated her and the knowledge that she had not been let go due to professional or competency issues, but due to the color of her skin.
Another African-American teacher subsequently submitted her resignation when the principal cut the theatre program she directed.
As the only African American teachers in the school, the three stated the consequences went beyond racial slurs, but lamented a school population with an absence of role models. "There is no one left here on the teaching staff that looks like us." Over half the student population at the school is black.
An investigation by the Department of Education, amidst protests, is underway to respond to the allegations of the vice principal's affidavit as well as to the statements made by the three teachers who were let go.
The New York Public School System, as any other school environment, should be a safe haven for young people to learn. Teachers and administrators are the role models that motivate our youth to achieve academic success and go on to be productive members of society. If you or someone you know has been a victim of race discrimination, it is in your best interest to speak with an authority on this subject to keep schools safe havens for our youths.

Tritton - Face Of Madness
Face Of Madness
by Lior "Steinmetal" Stein at 01 August 2013, 11:28 AM
Into the imagery of lunacy, mass psychosis, neurosis engulfs the uncertain and will drive them into chaos. What is the true face of madness? What lies within those empty eyes, seeking of a truth that isn't really there? Hospitalized maybe? Or maybe someone needs a good kick in the behinds in order to start seeing what truly matters? But matters to whom? That is scrutiny for you people, an inner argument that will never cease, time for a fistful of madness, and I was given to handle a young Mexican band, ready to burst with its old school wave of aptitude. Driven by British Metal, mainly NWOBHM and IRON MAIDEN, with jiffs and bits out of the US Bay Area Thrash and Speed Metal symbols, TRITTON commenced their raised for founding their own constructive Metal heirloom. On their own the five members revealed their debut release, "Face Of Madness", which is actually a continuance, and a reproduction, of an earlier demo that was named similarly.
On its whole, "Face Of Madness", most of the way at least, sounds like a selection of examples out of Britain right up through the middle era of the 80s. Metal became a little more intense but still consisted of the nostalgic melodic lines of the British wonders. In the case of TRITTON, a few of their melodic patterns insinuated closeness to the golden years of IRON MAIDEN, especially when it comes to the guitaring and a little of the sharp edged passages within the songs. Generally, there were demonstration of some serious musicianship with an old vibe, yet still amplified as fresh. "Flash From The Past", an instrumental epic, handled with care, well thought, bestows nearly everything that this band wished to offer, swift hook laden guitar licks producing enchanting harmonies partially played with mid tempo tremolo picking, classy solos that almost measured with early 80s manifestations and a catchy arrangement that won't tire, yet also there is a fine sense of steely speed, going straightforward with power. "Insurrection" is an additional example of solidity, signifying the admiration for MAIDEN, garnering such rich implementations of inflamed energies, warranting a fine tribute to the gods. When desiring to Thrash their way into recognition, TRITTON assumed the direct form of assault with "Wanton War", a heavy piece fiend, delivering swifts blows of iron and steel. Nonetheless, there is still the NWOBHM standard immersing from bellow.
Largely, TRITTON is a promising band, burning hard on Heavy Metal, once forged by the fires of the British steel, though also entrusting themselves to the brutish attitude of early Thrash and Speed Metal to rally force and additional heaviness to their aid. "Face Of Madness", frankly, has been too immediate for me, I need more of them to actually divulge another piece of my opinion regarding their efforts. It is a beyond what you would refer to as solid, but still I believe that these guys can do better. For one thing that I can proclaim is that I wasn't that incredulous by Lorena Cabrera as a vocalist. I agree that she has quite a voice, but for some reason it sounded too thin for what their band mates have been producing. Since their close proximity to IRON MAIDEN, I believe that a voice with depth would have done the trick. On the other hand, who knows, it might eventually work out and I will get the hang of it. As for the band itself, I salute them for their talents on applying both melodic and heavy music, paying a tribute to the classic era of Metal.

Rayleighverstrooiing is de verstrooiing van licht door deeltjes die kleiner zijn dan de golflengte van het licht. Het effect werd genoemd naar Lord Rayleigh die het verklaarde. Rayleighverstrooiing treedt op wanneer licht door een transparante vloeistof of vaste stof gaat, maar kan het duidelijkst worden waargenomen bij gassen. Rayleighverstrooiing in de atmosfeer is de reden waarom de onbewolkte lucht blauw is.

Deeltjesgrootte en golflengte
De hoeveelheid rayleighverstrooiing voor een lichtstraal is afhankelijk van de grootte van de deeltjes en de golflengte van het licht. De golflengte-afhankelijkheid is bijzonder sterk: de hoeveelheid verstrooid licht is omgekeerd evenredig met de vierde macht van de golflengte. In formulevorm is de intensiteit van een verstrooide lichtstraal:

waarbij R de afstand is tot een deeltje, θ de verstrooiingshoek ten opzichte van de invallende straal met intensiteit , n de brekingsindex van het deeltje, en d de diameter van het deeltje.

Indien het invallend licht gepolariseerd is (bijvoorbeeld van een laser), dan dient men in bovenstaande formule de term 1+cos²θ te vervangen door sin²θ.

Blauwe lucht

De sterke golflengte-afhankelijkheid  zorgt ervoor dat blauw licht veel meer wordt verstrooid dan rood licht: blauw licht heeft een golflengte die ongeveer twee keer zo kort is als rood licht, en blauw licht wordt daardoor  keer zo goed verstrooid. De atmosfeer verstrooit het licht naar alle kanten en geeft de zachtblauwe kleur behalve waar men de zon direct ziet.

Men zou dan ook kunnen denken: "Waarom is de hemel niet violet? De golflengte daarvan is immers nog kleiner." Maar de verklaring daarvan is dat het menselijk oog niet zo gevoelig is voor paars licht als voor blauw licht.

Het rode gedeelte van het licht wordt dus minder verstrooid en gaat verder door de dampkring heen of verlaat deze zelfs weer.

Rode zon
Het effect kan ook worden gezien bij zonsopgang en zonsondergang, wanneer het zonlicht een veel grotere afstand door de atmosfeer moet afleggen om bij de grond te komen. Deze extra weg door de atmosfeer zorgt voor nog meer verstrooiing van het blauwe – en in mindere mate groene – licht, maar nog steeds weinig verstrooiing van rood licht. Dit kan worden gezien als een duidelijke roodverkleuring van de hemel in de richting van de zon. In verzwakte vorm van dit effect zorgt de verzwakking van het blauwe licht voor een geelverkleuring van de zon.

Hetzelfde gebeurt ook wanneer de maan heel laag boven de horizon staat, waardoor maanlicht een lichte rode verkleuring ondergaat.

Andere verstrooiing
Als de deeltjes groter zijn dan de golflengte van het licht, dan is de mate van verstrooiing niet meer afhankelijk van de golflengte en kan het licht dus niet in verschillende kleuren scheiden. Zulke verstrooiingsprocessen kunnen bijvoorbeeld gezien worden in een wolk (de waterdruppels zijn groter dan de golflengte van het licht) die er dus in daglicht wit uitziet. Andere voorbeelden zijn in water opgeloste macromoleculen zoals in melk, zie Tyndall-effect.

R N Frost September 3, 2013 2
The "Fresher's Fair" is offered by every British university as part of a new academic year. Recruitment displays and tables filled the room—a large meeting hall—as new students were being recruited. If, for instance, an arriving freshman is interested in joining the university crew he would be drawn to the proper spot by a pair of crossed oars. The Thespians had their place, as did the Islamists, the New Atheists, a Glider Club, and more. There were a host of other clubs and societies.
The range of Christian options offered this year was unusual. The standard Christian Union stall could be found, of course, but this year a group of local churches were present in an effort to recruit students, each to their local setting. They were welcome as long as the booth representatives were university students.
Thomas, a fresher, moved through the crowded room, a bit nervous but curious. Just a month earlier he'd met Jesus through a Discover Christianity course. His question now was whether, as a student, he would move ahead with his newfound faith. He needed some help.
"You must come to our church!"
Thomas, pinched between a pair of earnest students, was looking at the iPad video of a worship service on a loop mode. Images of enthusiasm pulsated on the screen. A special feature was the worship team with a drummer drawing special notice—his skill was obvious as he pressed the pace of a popular chorus. "Our worship is an absolute highlight!" The video continued into close-ups of lively, young, attractive participants—arms raised, eyes closed, moving and singing—who were obviously experiencing something close to total bliss.
Thomas asked the students what their church offered and one answered.
"We've got the best music in the city," he was assured, "so our ministry draws students who love worship. If you believe in worship, this is the place for you."
He nodded, picked up an informational flyer, thanked them and moved on.
Next he came to a table stacked with copies of a pair of books and a small sign, "Free! Take one!" Some blown-up photos showed a young preacher spotlighted on a stage with a casual look—casual but stylish—and a Bible in his hand. Around him were circular tables filled with people along with some interspersed sofas and soft chairs. Everyone had their eyes riveted on the preacher whose teaching apparently had them enthralled.
"He's great," said the booth host. "He offers cutting edge truth and his first two books have been translated in four languages." It was clear that this was a church for people who meant to have an impact. "We have small group studies that give the kind of training you'll need while you're in the Uni. If you'd like to sign up with one that meets in your residence hall, here's the form!"
Thomas considered their emphasis: "So your church mainly features strong teaching?"
"Yes!" the host enthused, "Our pastor, Stephen, is brilliant! And the training program here is the best. Ever since Stephen planted our church four years ago we've doubled our numbers each year."
The next booth was more subdued yet a bit shocking. Here there was a table covered with photo-mosaics of children from a non-mainstream ethnicity. Their drawn faces, imploring looks, and their rough settings were explained by a label: "Our mission to the helpless!" One of the two students told Thomas about it.
"Our church is completely missional—if anyone is willing to work, our leaders put them to work. These pictures are from our Spring break last year when a group of us worked with the poorest of the poor in a nutritional supplement program. We have huge opportunities to help the poor during our Spring mission."
"What about the rest of the time? During the academic term?" Thomas asked.
"Oh, there's so much to do. Our church motto captures it: 'Offering the Gospel by the way we live!' Every Sunday, for instance, we have a soup kitchen we open just after our morning service and by now we have over thirty of the down-and-out locals coming each week. There are huge needs and we try to meet them. But we're really short-handed. Are you interested in helping?"
Thomas smiled, "Let me pray about it." He took yet another leaflet and moved on.
Once outside the meeting hall he sat on a bench and considered his options, thumbing through his flyers.
Ever since he met Jesus Thomas was delighted with worship, but he didn't see it as an end in itself. David, the man who first introduced him to Jesus in the Discover Christianity course, alerted him on that score: "Pursue a person, not an experience."
He thought about the charismatic pastor, Stephen. He meant to feed the mind but Thomas, though hungry to learn, was hesitant. His spiritual mentor David had coached him to ask about the focus of a church: "Pursue a person, not just knowledge." What seemed to be missing at that booth was a focus on Christ. Stephen was much more the feature figure.
The missional church was certainly attractive but David's advice once again came to mind. He talked about how the poor will always be among us—and we must care for them with Christ's compassion—but, David warned, "Be sure to pursue the person and not just good works no matter how noble they might be."
Somewhere, Thomas thought, there must be a church that delighted in Jesus and made him their ultimate focus—so that worship, learning, and ministry would be birthed out of his love. But for now Thomas knew he needed to keep looking.

Thanks for the helpful words, Ron. I'll be passing this post on to my daughter who starts at a university here in the States this week!
September 17, 2013 (9:08 pm)
This is a great story Ron. I wonder if Thomas has realised by the end of the narrative that his urge to 'move ahead' in his faith does not need to be based on joining any organisation?


Get ready for play the most adventure and heart failing game. You have played many water sliding and my dolphin water uphill racing games. Enjoyed a lot from sliding but this time the racing battle is to begin on the water slide means now you can drive the motorbike, BMX boy bicycle or racing sports cars on the sliding with your expertise. Uphill water slides are designed in mid-air, this game is not for just the boys game also this racing game for the girls too. Funny enjoyment driving race you can see and play in this water race adventure game.

I´m in St. John´s Nfld now Starting to work on reviewing the Simulator Project for the Coast Guard Auxiliary. We had a quick look at the thing yesterday - but today is the main tour and meetings to look at progress and answer questions.
On Sunday Thomas and I were able to take a bit of time away for a Hike up Signal Hill. It was a beautiful walk through some of the residential areas and then up into the park along the coast. I had completely forgotten About the fact that this is where the first radio transmissions were sent by Marconi testing trans Atlantic. So, I whipped out my HAM radio and forced Thomas to grab the picture you see.
We have been really fortunate with weather - albeit a bit windy - but that did afford us some nice swell when we made a side trip at the end of meetings yesterday out to Middle Cove. This is a beautiful little beach that has a somewhat troubled history for anyone in the Coast Guard/Auxiliary as a three man rescue team perished there in the late 80´s. It was all caught on video and is still shown for training. So, despite the natural beauty - it was a bit of a sombre visit.

DeepMind (früher Google DeepMind) ist ein Unternehmen, das sich auf die Programmierung einer künstlichen Intelligenz (KI) spezialisiert hat. DeepMind wurde im September 2010 gegründet und 2014 von Google LLC übernommen.

Geschichte
DeepMind Technologies war ein britisches Start-up, gegründet 2010 von Demis Hassabis, Shane Legg und Mustafa Suleyman. Zu den ersten Geldgebern gehörten die Venture-Capital-Unternehmen Horizons Ventures und Founders Fund sowie der Business Angel Scott Banister.

Am 26. Januar 2014 gab der US-Konzern Google bekannt, DeepMind Technologies übernommen und damit das ebenfalls an DeepMind interessierte Facebook ausgestochen zu haben – es war die bis dahin größte Übernahme des kalifornischen Unternehmens in Europa. Der Preis blieb geheim, Branchenkenner gingen von einem Kaufpreis von etwa 500 Millionen Dollar (365 Millionen Euro) aus. Mehrere Milliardäre hatten bereits in DeepMind investiert, darunter Elon Musk, CEO des privaten Raumfahrtunternehmens SpaceX und Elektroautohersteller Tesla Motors, Paypal-Gründer und ursprünglicher Facebook-Geldgeber Peter Thiel, der Skype-Mitgründer Jaan Tallinn sowie der Hongkonger Magnat Li Ka-shing von Horizon Ventures, einer der mächtigsten Männer Asiens.

Im Jahre 2014 erhielt DeepMind die Auszeichnung "Company of the Year" vom Cambridge Computer Laboratory.

Nach Übernahme wurde das Unternehmen in Google DeepMind umfirmiert. Google setzte auch einen Ethikrat ein, der sicherstellen soll, dass die Technologie von DeepMind nicht missbraucht wird. Die Struktur des Ethikrates blieb unklar.

2015 veröffentlichte das Unternehmen die Ergebnisse eines Forschungsprojektes, bei der die Künstliche Intelligenz alte Atari-Spiele selbstständig erlernen sollte. Nach Angaben von Google DeepMind gelang es der KI, sowohl die Spielregeln zu erlernen als auch Erfolgstaktiken selbstständig zu entwickeln.

Im Dezember 2019 kündigte einer der Gründer, Suleyman, an, dass er DeepMind verlassen würde, damit er bei Google arbeiten kann.

Forschung
Das offizielle Unternehmensziel von Google DeepMind ist, Intelligenz zu verstehen ("Solve Intelligence"). Im Gegensatz zu anderen Künstlichen Intelligenzen wie beispielsweise Deep Blue von IBM hat Google DeepMind kein vordefiniertes Ziel und ist somit flexibler in der Anwendung für verschiedene Probleme. Google DeepMind unterscheidet sich ebenfalls in der grundsätzlichen Strukturierung der Künstlichen Intelligenz. Statt ausschließlich auf ein neuronales Netz zu setzen, erweiterte man die KI mit einem Kurzzeitspeicher, um somit die Fähigkeit eines künstlichen Gedächtnisses zu simulieren. Die Entwickler von Google DeepMind bezeichnen die Künstliche Intelligenz deshalb auch als "neuronale Turingmaschine" und nicht als neuronales Netz.

Zu den leitenden Entwicklern zählt David Silver.

AlphaGo

Bei DeepMind wurde AlphaGo entwickelt, ein Computerprogramm, das ausschließlich das Brettspiel Go spielt. Im Oktober 2015 besiegte es den mehrfachen Europameister Fan Hui. Es ist damit das erste Programm, das unter Turnierbedingungen einen professionellen Go-Spieler schlagen konnte. Zwischen dem 9. und 15. März 2016 trat AlphaGo gegen den südkoreanischen Profi Lee Sedol, 9. Dan, an. Das Programm gewann nach fünf Runden mit 4:1.

Im Jahre 2017 wurde eine verbesserte Version namens AlphaGo Zero veröffentlicht, welche AlphaGo 100 zu 0 schlug, wobei die Strategien von AlphaGo Zero autonom erstellt wurden. Die Lernphase dauerte nur drei Tage, wobei AlphaGo im Vergleich Monate dazu brauchte.

AlphaZero

AlphaZero ist eine im Dezember 2017 erstmals in einer Veröffentlichung beschriebene Verallgemeinerung des oben erwähnten AlphaGo Zero. AlphaZero lernte die Beherrschung der drei Brettspiele Shōgi, Schach und Go auf höchstem Niveau nur anhand der Spielregeln und durch intensives Spielen gegen sich selbst, ohne die Nutzung von Daten zum Vorgehen menschlicher Spieler.

DeepNash
Die Software DeepNash spielt Stratego. Ihr gelang es im Jahr 2022, auf dem Niveau von menschlichen Spitzenspielern zu spielen. Gegen die besten menschlichen Spieler auf der Spieleplattform Gravon erreichte DeepNash eine Gewinnrate von 84 Prozent. DeepNash verwendet einen neuartigen Ansatz, der auf einer Kombination aus Spieltheorie und sogenanntem modellfreiem Deep Reinforcement Learning basiert. Die Software hat dafür etwa zehn Milliarden Mal gegen sich selbst gespielt und hatte das Ziel, ein so genanntes Nash-Gleichgewicht zu erreichen. Ein Spiel, das sich im Nash-Gleichgewicht befindet, verläuft stabil, denn das einseitige Abweichen von der Strategie würde einen Nachteil bedeuten.

Die Entwicklung einer spielstarken Stratego-Software ist eine enorme Herausforderung, weil die Anzahl der möglichen Spielzustände auch im Vergleich zu Schach, Go und Texas Hold'em außergewöhnlich ist. Weil die Komplexität des Spielbaums von Stratego so groß ist, ist es nicht möglich, eine Monte-Carlo-Baumsuche (englisch Monte Carlo tree search) zu verwenden.

AlphaStar
Im Januar 2019 wurde AlphaStar vorgestellt, ein KI-Programm, das das Echtzeit-Strategiespiel StarCraft II spielt. Wie AlphaGo handelt es sich dabei um ein künstliches neuronales Netz, das zunächst menschliche Spieler imitierte und dann mit Reinforcement Learning trainiert wurde. In zwei Sätzen zu je fünf Spielen gegen die professionellen Spieler Dario "TLO" Wünsch und Grzegorz "MaNa" Komincz gewann AlphaStar jedes Spiel. Die Anzahl der Aktionen pro Minute wurde auf ein für Menschen übliches Maß beschränkt. Im Gegensatz zu menschlichen Spielern hat AlphaStar jederzeit einen vollständigen Überblick über die sichtbaren Teile der Karte, fokussiert sich aber dennoch immer nur auf einzelne Bereiche. Ein bei der Vorstellung live übertragenes Spiel konnte MaNa für sich entscheiden. Besondere Stärken von AlphaStar waren Micromanagement und Multitasking. Im letzten Spiel wurde sie durch ungewöhnliche Aktionen des menschlichen Spielers aus dem Tritt gebracht. Eine Weiterentwicklung trat ab Juli 2019 anonym in Ranglisten gegen echte Spieler an und erreichte in allen 3 "Rassen" die höchste Liga.

AlphaFold

Seit 2016 arbeitete DeepMind auch am Problem, die dreidimensionale Struktur der Proteine nur anhand der Abfolge der Aminosäuren des Proteins vorherzusagen. 2018 nahm das von DeepMind für dieses Problem entwickelte KI-Programm AlphaFold am Gemeinschaftsexperiment CASP teil. Dies ist eine Art Wettbewerb, bei dem KI-Programme verschiedener Institutionen genutzt werden, um die Strukturen von Proteinen vorherzusagen. Diese sind den CASP-Veranstaltern bekannt, aber der Öffentlichkeit und den CASP-Teilnehmern nicht. So ist es möglich, die Qualität der Vorhersagen zu beurteilen. DeepMinds AlphaFold schnitt dabei bereits bei seiner ersten Teilnahme 2018 besser ab als die Programme der etwa 100 weiteren Teams. Beim nächsten CASP-Wettbewerb im Jahr 2020 war die Vorhersagequalität des zweiten von DeepMind entwickelten Programms AlphaFold2 so gut, dass Wissenschaftler und auch DeepMind urteilten, dass das jahrzehntealte Problem der Proteinfaltung erstmals als gelöst betrachtet werden könne – das sei ein Meilenstein der Strukturbiologie. Am 15. Juli 2021 veröffentlichte DeepMind eine quelloffene Version von AlphaFold 2 und veröffentlichte die Funktionsweise im Fachjournal Nature.

MuZero
In den Jahren 2019 und 2020 veröffentlichte eine Forschergruppe von DeepMind den Algorithmus MuZero, der eine Baumsuche mit einem individuell entwickelten Machine-Learning Model kombiniert. MuZero beruht auf Deep Reinforcement Learning und stellt eine Weiterentwicklung der schon in AlphaGo, AlphaGo Zero und AlphaZero verwendeten Technologien dar. Im Gegensatz zur "Alpha"-Serie von KI-Systemen ist MuZero nicht mehr auf eine bestimmte Wissensdomäne oder Anwendungsbereich festgelegt. Es ist keine Voreinstellung von Regeln mehr nötig und auch keine durch Menschen gesteuerte Initialisierung mit Trainingsdaten. Das MuZero-Softwaresystem erlernt diese Regeln selbstständig durch Beobachtung der Umgebung, und vor allem verfeinert es sein selbst aufgestelltes Modell und bestimmte Aspekte des eigenen Entscheidungsprozesses. Ein Vergleich des fertig optimierten MuZero mit anderen KI-Systemen ergab eine mindestens gleichwertige Leistung bei Computergo und Computerschach, aber auch in "Atarigames" wie Ms. Pac-Man.

WaveNet
WaveNet ist ein neuronales Netzwerk, das ursprünglich ab ca. 2014 zum Zweck der verbesserten, natürlicher klingenden Text-to-Speech-Synthese (TTS) entwickelt wurde, sprich, für menschlicher klingende Vorlesesysteme, indem das Programm natürliche menschliche Stimmen analysieren sollte, um so auch natürlicher klingende Sprache beim Vorlesen von Texten erzeugen zu können. Seit März 2018 bietet Google das auf WaveNet basierende Vorleseprogramm Cloud Text-to-Speech im Rahmen von Google Assistant an.

Inzwischen forscht DeepMind aber auch aktiv daran, mit WaveNet existierende individuelle menschliche Stimmen nicht nur zum Vorlesen von Texten möglichst exakt nachzubilden, um es mit ähnlichen Funktionen wie etwa das 2016 von Adobe Inc. vorgestellte Adobe Voco auszustatten. Ein Forschungsbericht vom Juni 2018 mit dem Titel Disentangled Sequential Autoencoder ("Entflochtener sequentieller, automatischer Stimmgenerator") stellt fest, dass es erfolgreich gelungen sei, WaveNet dafür einzusetzen, die Stimme in einer existierenden Tonaufnahme durch jegliche andere reale Stimme zu ersetzen, die denselben Text spricht ("content swapping"). Um diese Fähigkeit zu ermöglichen, seien ca. 50 Stunden an Aufnahmen jeweils der Quell- wie Zielstimme nötig, mit denen WaveNet die grundlegenden Eigenschaften der beiden Stimmen erst lernen muss (wobei es selbstständig ein jeweils eigenes, von den Sprachaufnahmen abstrahiertes Modell der zu erlernenden Stimme erstellt), bevor es die Stimmkonvertierung bei jeder beliebigen neuen Tonaufnahme in annehmbarer Qualität durchführen kann. Die Autoren des Forschungsberichts betonen außerdem, dass WaveNet dazu in der Lage sei, statische und dynamische Eigenschaften voneinander zu unterscheiden (zu: "entflechten"), d. h., das Programm trenne automatisch zwischen den bei der Stimmkonvertierung beizubehaltenden Eigenschaften (Textinhalt, Modulation, Geschwindigkeit, Stimmung usw.) und den zu konvertierenden Grundeigenschaften der Quell- wie Zielstimme.

In einem Nachfolgebericht mit dem Titel Unsupervised speech representation learning using WaveNet autoencoders ("Selbständiges Sprachmodellernen mit WaveNet") vom Januar 2019 hieß es, dass DeepMind die Unterscheidung statischer von dynamischen Stimmeigenschaften von WaveNet weiter verbessert habe. In dem weiteren Nachfolgebericht Sample Efficient Adaptive Text-to-Speech ("Samplingeffizienz bei adaptiver Text-to-Speech-Synthese") vom September 2018 (letzte Revision Januar 2019) berichtet DeepMind, das Minimum an benötigten Sprachaufnahmen für das Sampeln einer Stimme inzwischen auf wenige Minuten reduziert zu haben.

Im bereits 2014 veröffentlichten Bericht Towards End-to-End Speech Recognition with Recurrent Neural Networks ("Zur vollständigen Spracherkennung mittels rückgekoppelter neuronaler Netze") verwies DeepMind auf erfolgreiche Versuche, WaveNet zur automatischen Verschriftlichung von existierenden Sprachaufnahmen einzusetzen.

Der Forschungsbericht Large-Scale Visual Speech Recognition ("Allgemein einsetzbare optische Spracherkennung") vom Juli 2018 (letzte Revision vom Oktober 2018) geht auf erfolgreiche Versuche ein, WaveNet zum Lippenlesen bei menschlichen Lippenbewegungen auch in völlig stummen Videoaufnahmen einzusetzen, wobei das Programm professionelle menschliche Lippenleser beim Erraten der tatsächlichen Laute bereits deutlich übertreffe. Dieses Feature scheint als eigenständiges WaveNet-Plugin unter dem Titel LipNet entwickelt zu werden.

Gesundheitsdaten
Im Februar 2016 gab die Firma bekannt, dass es in Großbritannien mit der Gesundheitsbehörde National Health Service zusammenarbeitet, um eine iPhone-App mit dem Namen "Streams" zu entwickeln, allerdings sei es noch zu früh, um sagen zu können, wo KI angewandt werden könnte. Diese soll dabei helfen, Patienten zu überwachen, die an einem "Nierenschaden" leiden. April 2016 veröffentlichte das Fachmagazin "New Scientist" Details der Vereinbarung, demnach erhält Google den Zugriff auf die Daten von 1,6 Millionen NHS-Versicherten, die jährlich in den drei Krankenhäusern – Barnet, Chase Farm and the Royal Free – des Royal Free NHS Trust behandelt werden. Die weitreichende Vereinbarung erlaubt einen Datenaustausch weit über das bekannt gegebene hinaus. Enthalten sind die Daten von HIV-positiven Patienten, Drogenabhängigen oder Frauen, die Abtreibungen vornehmen ließen. Eine Opt-out-Möglichkeit (Möglichkeit der Verweigerung) für Patienten gab es nicht. Neben den pathologischen und radiologischen Ergebnissen werden die Daten der Intensivmedizin und der Notfallabteilungen übertragen sowie die vollständigen Tagesaktivitäten der Kliniken, der Zustand und die Unterbringung der Patienten und die Krankenhausbesuche (wer und wann) übermittelt. Darüber hinaus bedeutet der Datenzugang auf die zentralen Aufzeichnungen aller NHS-Krankenhaus-Behandlungen in Großbritannien, dass es auf historische Daten der vergangenen fünf Jahre zurückgreifen kann – zusätzlich zu den neu auflaufenden Daten.

Kritiker fürchten dabei um die Intimsphäre und den Datenschutz. Das Personal von Google soll aber nicht in der Lage sein, bestimmte Patienten zu identifizieren, und die Daten sollen nicht mit Google-Konten oder Produkten verbunden werden, erklärte Mustafa Suleyman, Leiter des Bereichs "Angewandte KI" bei DeepMind.

DeepMind Ethics and Society
Im Oktober 2017 kündigte DeepMind an, das Forschungsabteil DeepMind Ethics & Society zu gründen, welche sich mit den folgenden Themen beschäftigen soll: Privatsphäre, Transparenz und Gerechtigkeit und wirtschaftliche Folgen davon.

Best School Lunch in 22 Years!
Hi. I'm 77 years old and I am from Port St. Lucie, FL 34984, and I am also with Council of the Aging. I'm writing to you to say thank you for so much. The pantry meals are great. I don't know you all, but I'm happy for what you do for people like me. May God bless all of you. Merry Christmas and Happy New Years. P.S. Let there be peace on earth one day. P.S. Love you all.
[I] have been a very happy customer of GAFoods for over four years through my LTC [long term care] Plan with Sunshine Health. My new case manager with United Health Care will contact you to continue to deliver frozen meals to my home, only now through UHC. Am interested in facts in your ebook download. Thank you.
SunMeadow scored perfectly at the PCA food evaluation today. All of the components of each meal evaluated looked, tasted, and measured perfectly. The customer randomly selected the following meals from stock - Crispy Breaded Chicken with Diced Sweet Potatoes and Vegetable Medley, Chicken Stew with Pineapple Coconut Dessert, Haddock Nugget with Carrots and Garlic Mashed Potatoes, and Western Omelet with Potatoes O'Brien and Strawberry Applesauce from our Classic Cuisine, All American, and Rise & Shine menus.
"May God forever bless you!" A managed care member, BR, called to let us know she was eating her omelette and her potatoes and absolutely loves them! She also said she loves her driver (Rafael Sanabria)! She is very thankful for GA Foods' service!
Your driver Michael took his time to get me to a warmer part of my house. He then called his office and they contacted my case manager who was able to send help to get my heater fixed. Thank you.
I just received a call from a client in Kentucky, RH. She called to tell us what a wonderful driver Mike is and that she just cares about him so much. She has been with GA Foods for 3 years. In the past, when her husband had fallen, Mike helped him off the ground on multiple occasions. On one visit, her husband had become lodged between the wall and his wheel chair. Mike happened be scheduled to make a delivery and eagerly helped. Two days later her husband had passed away. RH feels Mike goes above and beyond what would be expected and needs to be appreciated for being so kind. She said she wishes Mike could sit down and have a cup coffee with her. He is just the sweetest person.
GA Foods' deliveryman Buck Brown was delivering to a member of ours who is usually waiting for him at the door. Buck has a good rapport with him and since the member wasn't there, and that was unusual, Buck thought something might be wrong. He tried the door handle and peeked his head in the house and saw the member sitting in a chair. Buck called out his name a few times with no response but a low gurgling noise. Buck called 911 and stayed with the member until the EMS arrived. Having an extra set of eyes and ears for home delivered meal clients can save lives.
The carrot salad with the cold sandwich meals was a big, big hit!!! Clients are asking for more of it.
This letter is in reference to your shelf stable breakfast meal. I am a US Army soldier undergoing Basic Combat Training at Fort Sill, Oklahoma. I graduate this upcoming weekend, the 20th of June. (Hooah!) One of my favorite daily occurrences is chow, and honestly, I love your breakfast meals. They are convenient and nutritious and I think they taste great. As a consumer, I am curious if the shelf meal is available for commercial resale. These meals would eliminate the need for a lunchbox in my household. Overall, I felt the desire to share my appreciation for your product. Thank you for providing this product!
We are very grateful to SunMeadow/GA Foods. In particular, it has been wonderful to work with you and your outstanding delivery driver, Jared. Without your help, we would have had great difficulty in getting nutritious meals to anyone. Jared has been a true blessing for all of us in his efforts to do more than merely deliver meals; he took the time to truly help people.
You're a blessing. As is your food service and, especially Marcus, the driver. Your food is tasty and packaged well. Marcus is conscientious and excels in communication. Thanks!
I live 8 miles from New Orleans and was deeply affected by Hurricane Katrina. Your meals really saved us. We had no grocery stores opened until over a month after Katrina, and couldn't get to out of town groceries.
My family and I received food boxes after Hurricane Wilma; we were so relieved to have some food. We had been walking to the market daily, just to get necessities.
I am sending you this letter as a thank you for your wonderful meal kits; they were real life savers for New Orleans residents.


A few days ago, Roger Alan Koza's blog Ojos Abiertos posted a text by Argentinean filmmaker Nicolás Prividera claiming that the critical praise for Leos Carax's Holy Motors and Wes Anderson's Moonrise Kingdom was symptomatic of the 'exhaustion' of the film cannons that validate them.
As Prividera's text raises some interesting issues about the hegemonic –yet outdated– Eurocentrism in international film culture, TropicalFRONT decided to translate the piece into English and post it here to make it accessible to a larger audience, and to contribute to the larger debate on the need for criticism that take into account the tradition and influences of non-European cinemas. Thanks to Roger Alan Koza.
After the prophesied end of the world, it's clear that when it finally does come it will be "not with a bang, but a whimper" as Eliot poetized. It's something cinema has been preparing us for a while: the tiresome epic for an era in which "the old is not finished dying, and the new is not finished being born." For there are Old Europe and the not so young United States, under the weight of mandates they don't know how to re-create (Europe was a common market before being a polis and "America" a land in which the citizens still defend their right to bear arms, as if living in an eternal western). Because that's what it's about: reinventing tradition rather than succumbing to it. But I won't get into here—even if film is our subject—the exhausted state of Old Hollywood and the New European cinemas, evident for at least two decades (not coincidentally, the time when Hollywood set aside '60s juvenilia and Europe sought new territories to discover and evangelize about).
I will take two films acclaimed for their apparent fresh air, even if this acclaim is only due to their eccentricity toward their respective canons. Which doesn't mean they are ex-centric, but rather loyal representatives of the exhausted state of their traditions. That is to say they interest me for being symptomatic, by contrast, of one of the major problems of contemporary cinema and culture: the vacuous restatement of a tradition (whether that of classicism or the vanguard) turned into an empty shell, but supported by a legitimization system that keeps it alive artificially. And that Old Europe and the not so young United States are in profound crisis yet they still have the power to tell us not only what to watch, but how to understand modernity.
If Thoreau wanted to convert the insular world of Walden into its own continent, Anderson fashions from his island an (in?)voluntary metaphor of the Unites States. It's for this reason Moonrise Kingdom is his most representative work as concerns the naïve reproduction of "America" as an island of Lost Children. Because this is not a portrait of lost childhood, but rather one of getting lost in an infantile gaze. (To understand the difference, just consider the films with children by Rossellini or Bresson: The Devil, Probably and Germany Year Zero are not infantile films...). And it's that Anderson's interrupted innocence is stripped of Ford's savagery, as well as Capra's idealistic wake (without the precipitated mix of both these masters that Spielberg pursues as recently as in Lincoln).
We can't picture Anderson's pasteurized Houlden Caulfields shooting their congeners, like those of Gus Van Sant. Yet neither do they rebel as in Melody (where British cinema redeems itself for once from Dickensian Realism, thanks to a tradition that has also created works that haven't needed to give up imagination when talking about the end of childhood, like Alice and Peter Pan; this a good spot to claim another "minor" film, like Tideland by Terry Gilliam). This film had all the freshness and vitality missing from the predictable geometry of Moonrise Kingdom and its self-absorbed reconstruction of the '60s as "a moment in the land of happiness" (as the '50s were to '80s conservatives: enough to remember the idyllic past of Back to the Future, which included a direct reference to It's a Wonderful Life). Retro is exactly that: the vocation of alienating one's own era in the "happy world" of the past (happy even in the yellow tones and bittersweetness of nostalgia), but adding the anomie of the present. Kids from the '90s transplanted to the '60s: the kidnapping and death of History at the altar of lost illusions (now we could say that this altar which Antoine Doinel erected to Balzac in The 400 Hundred Blows somehow foretold that interpretation, which gets repeated with each dull imitation of Truffaut's fifty-year-old-plus film).
Something like this is also present in Carax, but how could it be otherwise with a spoiled young promise: juvenilia becomes decadence. Because the tradition of Holy Motors is something else: surrealism as an outbreak of the bad European conscience in a moment of crisis. We're no longer dealing with a walk in unredeemed wild America but rather through the ruins of European civilization. A tour through the masks of a disenchanted and subjected imagination: subversion made part of the system, as an assumed legacy of the Pyrrhic victory of the avant-garde. The film, like its protagonist, becomes a slave to its agenda and its agency, and all that's left is to surrender to its job with a grimace of disgust. Or perhaps it signals precisely that defection of art under late capitalism: the representation of evil does not deliver us from evil, rather it is evil itself in its deepest banality. For not even death can be assumed in a world that denies the discreet charm of tragedy.
An exterminating angel signals the phantom of liberty. The spectrum invoked by Carax is that of Buñuel, but less the one of the '30s than of the '60s: that one who, in the midst of parricidal breaks from New Waves, foresaw his own classic countercriticism, his warning against that obscure object of vanguard desire that awaited him at the end of the road: not being able to escape the invitation of the bourgeoisie. Carax is resigned to not being able to leave, but chooses to become an unwelcome guest: still, he becomes the life of the party, and Holy Motors is chosen by critics as the best of the year, although its surrealist classicism opposes the neo-Bazinism that dominates much of contemporary cinema. It's that Carax offers them the perfect alibi, because by encapsulating himself in references to film genres, he ends up being recaptured by the obscure side of cinephilia. So what could have been a fierce criticism of European reason and its unfinished modernity becomes a funereal monument to the lights of the hand of the Lumière brothers.
Perhaps the great failed film of the year is Cosmopolis, which brings together Carax's insomniac limousines and Anderson's old young kids. But with Cronenberg there is neither innocence nor bad conscience, but a confinement (made up by dead gestures and false movements) in which the characters, exhausted or undaunted, cannot stop talking and speechifying as the known world collapses. And yet it is far more interesting than the rain of intimate films about the end of the world that invaded us (also from Europe—Melancolia—and the United States—4.44). But we already know that it is easier to imagine the end of the world than the end of capitalism.
*Nicolás Prividera (Buenos Aires, 1970) is an Argentine filmmaker. He's directed the films M (2007), and Tierra de los Padres / Fatherland (2011).

This is the most perfectly named glass! Tahitian Pearl ltd run is one of the newest CoE 104 lampwork colours coming out this winter from Creation is Messy. Tahitian Pearl is just dreamy to work with, it is super soft and buttery when melted and it has the most subtle metallic silver shimmer even when worked in a neutral flame.
These leaves and spacers have been created in a neutral flame - I flashed the leaves in and out of the flame a couple of time once they were formed to create a little more silver surface shimmer.
To get an even more pronounced silver metallic finish you can waft your bead through a slightly propane or oxygen rich flame to add a deeper and richer patina.
The petals on these flower beads were swiped on to the blue base bead in an oxygen rich flame, the resulting silver patina looks like brushed pewter.
To create this striped lentil bead I swiped on thick clear Effetre 006 stringers over a base of Tahitian Pearl to mask and protect parts of the original soft smoke grey rod colour from reacting to the flame chemistry. I melted the clear lines down flat and pressed the bead in a brass press then wafted the bead trough a propane rich flame few times to bring out the metallic patina on the non masked areas. In a propane rich environment the patina comes out looking industrial and textured.
These sweet and simple rustic hoop beads are one of my favourte styles of bead to create. In Tahitian pearl they look especially pretty.


Want to alleviate stress or cope with depression? Exercise may help. Increasingly, there is evidence from researchers that certain levels of physical activity can positively affect mental health. Len Kravitz, PhD, researcher and program coordinator of exercise science at the University of New Mexico, Albuquerque, takes a look at what research has discovered about the connection between exercise and mental health.
A growing body of research over the last 10 years shows that physical activity and exercise also improve psychological well-being (Dubbert 2002). Published data show that people with higher levels of fitness are capable of managing stress more effectively than those who are less fit (Hassmen, Koivula & Uutela 2000). It appears that cardiovascular exercise is the method that most benefits stress reduction. The research indicates that moderate-intensity aerobic exercise, performed three times a week (sessions lasting over 20 minutes) for up to 12 weeks, has the most influence on stress management.
The antidepressant action is one of the most commonly accepted psychological benefits of exercise. Patients diagnosed with depression have credited exercise as being an important element in comprehensive treatment programs for depression (Dunn et al. 2002). Cardiovascular and resistance exercise seem to be equally effective in producing antidepressive effects (Brosse et al. 2002). It also appears that both a one-time exercise session and chronic exercise training programs have a positive effect on people with clinical depression (Dunn et al. 2002). Research does imply, though, that the greatest antidepressive effects occur after 17 weeks of exercise, although you can observe improvements after 4 weeks (Scully et al. 1998). The effects of exercise on depression seem the same for men and women.
The results of over 30 published papers show a link between acute and chronic exercise and the reduction of anxiety (Scully et al. 1998). There appears to be much debate about whether low-intensity, moderate-intensity or high-intensity aerobic exercise is most beneficial. (If you're not sure at what intensity you should exercise, consult with a personal trainer.) It appears that even short bursts of 5 minutes of cardiovascular exercise stimulate anti-anxiety effects. The research also indicates that people who train for periods of 10–15 weeks receive the greatest beneficial effects.
This handout is a service of IDEA, the leading international membership association in the health and fitness industry, www.ideafit.com.
It appears that cardiovascular and resistance exercise can positively affect various mood states, including tension, fatigue, anger and vigor (a psychological variable defining vitality or energy) in normal and clinical populations (Lane & Lovejoy 2001; Fox 1999). Plus, it has been shown that even a single session of 25–60 minutes of aerobic exercise (at low, moderate or high intensities) increases positive mood feelings while also decreasing negative mood feelings. Researchers need to further research resistance training to learn more about the connection between it and mood state.

Leonid Siveriver's latest cycle of work reflects a synthesis of over twenty years of multidisciplinary evolution. Though no one in his family was artistically inclined, he claims that in his earliest childhood memories, he was always drawing or painting. By the age of eleven, he requested to be enrolled in an art school in his native Ukraine. The instruction, characterized by the rigidly classical approach of Eastern European and Soviet education, though an excellent foundation for developing skills, was very limiting.
In 1971, at the age of fourteen, Siveriver immigrated with his family to Israel, where he was exposed to the spectrum of Middle-East, Western European and American culture and expression. Israel in the '70s, though small and struggling, offered much broader horizons to a culture-hungry adolescent than a small town in Ukraine. He recalls that one of the great stimuli of his youth was encountering jazz. Decades later, his passion for jazz remains an undercurrent in his visual work: improvisation within boundaries. Knowledge rooted in discipline allows innovation, a breaking away.
Art education at his high school in Israel was minimal, but at least the approach was very fresh. Exposed for the first time to rudimentary ceramic techniques, mostly handbuilding and some basic glazing techniques, sparked his drive to develop as an artisan. The environment was, as yet, insulated , with very little art on offer. He invested time in doing his own drawings and set design for the school theatrical productions. Age eighteen: compulsory conscription. Three years in the army halted all progress - a period he describes as "totally dead". Upon discharge, he was desperate to get back into the most stimulating environment available.
Leonid laughs at the anecdote relating to his application to the Ceramics Design Department at the Bezalel Academy in Jerusalem. It was all because of timing. His release from the army was relatively late for the application deadlines to various departments; all, that is, except for one. So, although his primary interest was sculpture, he was accepted by the Ceramics Department, thinking that he would transfer to the Fine Arts Department during the following semester.
Early in the academic year, he saw, for the first time, a demonstration of wheel throwing, sparking a lifelong love affair with this unknown medium . "I was totally mesmerized," he recalls.
Bezalel offers a well-rounded curriculum, requiring exposure to many mediums as well as liberal arts electives, technical disciplines such as photography and animation, and art history. In the early 1970s, the pioneering Gedula Ogen, best known for architectural ceramics and sculpture for public buildings, headed the department. Other profound influences were Lydia Zavadsky, internationally reknowned for wheel works on a grand scale, and versatile Edith Adi (pronounced Ee-deet Ah-dee), an expert on surface treatment.
Siveriver recalls that his class was a remarkable collection of students. They propelled each other forward with a lively, friendly competition that, for many of these post-army young people, pushed them to a near-delirium of constant creativity.
The Ceramics Department was very large, with many large kilns and sufficiently spacious work areas for even the most ambitious projects. He became fascinated with building very large forms on the wheel using the sectional technique, the signature style of the USA's Toshiku Takayesu. Fortunately, though the Department required a certain number of projects that emphasized functionality, the teaching staff was supportive about a student's direction for personal expression. Siveriver fulfilled the required assignments, but his focus early on was expressive form.
At Bezalel, students explored the entire firing spectrum, from the lowest range all the way up to the highest stoneware/porcelain range. Students were also required to execute projects in industrial disciplines of model and mold making, casting, and mass production. Lathe-turned plaster, sledging, and even employing plaster-filled balloons were techniques taught for modeling both functional and sculptural forms. Clay-body and glaze composition were also required, as well as chemistry and applied geometry.
Within this spectrum of disciplines, each student was encouraged to develop a personal direction. Interdepartmental electives were also encouraged. Siveriver concentrated on drawing, photography, and clay, art history and history. And jazz.
Returning to Jerusalem in 1984, Siveriver discovered raku. At the time, the Bezalel Academy had no master's program, but talented graduates were sometimes invited to combine an instructorship with further study. This served as a pilot toward developing the school's masters' programs, referred to as "Fifth Year".
A couple of students who had summered in the USA early in the 1980s brought back information about this exciting Japanese technique, including glaze and clay body recipes and photographs. Students researched tools, kiln building and firing, and the technique became established. Siveriver, enthralled with this raw, spontaneous, unpredictable and dramatic craft, felt it answered to something he'd always been seeking internally. "My first horned pieces were done in that fifth year", he recalls, "and raku was the only technique I could imagine for their execution. "Besides," he smiles, "I was always a bit of a pyromaniac".
Aside from teaching at the Ceramics Department, Siveriver taught drawing, sculpture and ceramics at various art education centers around Jerusalem. Towards the end of that year, he was still feeling restless; wanting to travel but still be able to produce. From a sculptor friend he heard about an apprenticeship program in the USA.
In the fall of 1986, Siveriver began an apprenticeship at the Johnson Atelier in Mercerville, New Jersey. The program offered a non-degree teaching environment for two years, with a technical emphasis. Concentrating on refining the range of techniques learned at the Tomassi Foundry, instruction covered the Lost Wax Process, rubber and plaster molds, metal casting, sand casting, welding, metal chasing, pouring, surface finishing and patinas. His exploration of form grew out of an ongoing study of ancient cultures.
In the USSR of his childhood, religion was suppressed. In Israel, religions permeated everyday life, from Jewish and Christian ceremonial objects, prominent church and mosque architecture, the sinuous calligraphy and dazzling tile work of Islam, Bronze Age and Roman artifacts and ruins. Siveriver never gravitated toward any formalization of faith, but through his sculpture began to examine a universal language of symbols.
Thus, his work during the atelier years reveals hints of animistic or ghostly forms, altars, and objects suggesting ritual function.
At the Altelier, Siveriver met the young sculptor and painter Amy Medford, who became his wife. In 1989 they traveled to Pietrasanta to pursue their work independently for an entire year. When the couple returned to the USA in 1990, the hard work and skills fostered in Italy sustained them in their search for coping with the new reality of making a viable living. Initially, Siveriver began to teach and Medford managed a sculpture garden. Soon, however, they formulated a business plan and launched their model-making enterprise, Avant-Garde Studios (www.ags3D.com) The couple accepts commissions for figurines, action figures and toys, sculptures for public places, museum reproductions, portraits, and even computer models. It took about a decade to get well-established, but equally as important for Siveriver, there was always time for personal development of his work.
In addition, as a result of his work in a state program, the New Jersey School of the Arts (described as a "school without walls" and now, sadly, de-funded and defunct), he was recommended for a very desirable teaching position. The job involved creating the Ceramics curriculum for the prestigious Lawrenceville School, and to design and build the Ceramics Department from the ground up. He continues to teach there today.
"My work has long developed in two parallel directions," muses Siveriver. "I love the human body, so figurative work has always compelled me. The decade between the 'seventies and the 'eighties was not, worldwide, conducive to figurative work, so I was a bit isolated in my expression. The second strong influence is my fascination for ancient cultures. My focus has always been more intuitive than academic; rooted more in observation and association than analysis. Simple volumes, simple contours – these things move me towards a minimalist expression. The primal power of sources I find in African masks, Celtic sculpture and illuminations, Far Eastern, Islamic, and Native American art offer a wide range of powerful symbols.
Siveriver's current series of works, executed over the last three years, found expression in raku. The ritual origin, the visual aspects, and not least, the unpredictability all are aspects of the expression. This body of work is his first to be almost totally improvised, as all previous work had been carefully deliberated, with numerous sketches and forethought strategies.

Storerooms in archives, in trade and industry, in the office and in the workshop are always too small. The sliding shelf unit provides double the storage space. The principle is simple: the individual shelf units are pushed together and opened only where something needs to be taken out. The individual components of the shelf unit roll smoothly on rails. The sliding shelf unit is easy to operate even when it is fully loaded. If the sliding shelf unit is located in a freely accessible room, it can be secured by a robust central locking system with a cylinder lock.
The shelves feature a load capacity of 80 or 150 kg. The shelves are available in a plain specification or with rows of slots for subdivision with dividers. Shelf front cover strips can be installed to enable you to store loose material neatly and tidily.
The sliding shelf unit is supplied disassembled in packaging units. Thanks to the clever design of the complete system, the sliding shelf unit can be assembled in a short time.
For perfect storage of A4 or C4 documents, transparent sheets, etc. in sliding tray units. Pull-out suspension filing frames can be integrated inside a shelf unit.
