I'm interested in Sklyanin Algebras or Artin-Shelter regular algebras of type A. These are generated in degree 1 by three variables x,y,z, and have three defining relations in degree 2, which you can get by multiplying the matrix $$M=\begin{pmatrix} cx & bz & ay \\ az & cy & bx \\ by & ax & cz\end{pmatrix}$$ either on the left or right by the row/column vector of variables. (For every triple of numbers $a$, $b$, $c$, excluding a finite set, you get one of these algebras.)
Such algebras $A$ contain a central regular element of degree $3$, let me call it $g$. It has the property that $A/gA$ is the twisted homogeneous coordinate ring of the scheme of point modules of $A$, which is the cubic curve defined by $\det M$. $$g=c(c^3-b^3)y^3+b(c^3-a^3)yxz+a(b^3-c^3)xyz+c(a^3-c^3)x^3$$
This central element $g$ seems somewhat mysterious. In the original paper by Artin-Shelter it was apparently found by a computer search, in the foundational paper by Artin-Tate-Van den Bergh, only its existence (and its properties) are proved.
My question is: is there a conceptual way to get this element $g$? Sorry, it's a little vague. Thanks for any insight into this matter.
share|improve this question
If translation by the point $\tau$ of the elliptic curve $E$ has infinite order, then the center of $A$ is $k[g]$. That's the only intrinsic description of $g$ I know. There might be more known about the two central elements in the Sklyanin algebra of GKdim 4. Paul Smith has some notes that might be useful there: math.washington.edu/~smith/Research/Skly-survey.pdf – Graham Leuschke Apr 25 '13 at 20:22

How Many National Parks Are There?
Depends How You Ask
Dec 29, 2022 | By Will Hurd
Santa Elena Canyon in Big Bend National Park
8 min read
When it comes to the question of how many national parks there are in the US, the answer isn't as straightforward as you might imagine. It all depends on what you mean by "national park." In this blog, we'll dive into the different definitions and explain why the answer isn't so simple.
There are a few different ways to answer the question, "how many national parks there are in the US?" If you're asking how many national parks in the United States are specifically designated as "national parks" by the National Park Service, the answer is 63. However, in addition to these 63 national parks the National Park Service (NPS) also manages other types of federal lands. If you count all the places that the NPS manages, the number jumps up to 425 as of November 2023.
This larger number includes places that are designated as national monuments, national preserves, national historic sites, national recreation areas, and more. While these places are managed by the NPS, they aren't technically considered "national parks" even though they are often referred to as such.
Before breaking down the different kinds of places managed by the NPS in the national parks system, let me share my favorites.
My Top 5 Favs
I served as the co-chair of the National Parks Caucus when I was in Congress. I represented 8 of America's national parks in my congressional district. These experiences taught me the importance of conserving our nation's natural and cultural heritage for the benefit of current and future generations.
I didn't have the opportunity to visit national parks when I was a kid, but it's something I love to do now. While California has the most national parks, and not every state has a national park, It's easy to find your park near you. Once you do, I guarantee visiting them will become a lifelong passion. Here are my top 5 favorites:
Haleakalā National Park

Haleakalā National Park is located on the island of Maui in Hawaii. It is known for its stunning sunrise views from the summit of Haleakala, a massive volcano. One of the highlights of this park is the chance to see the endangered Hawaiian goose, known as the Nēnē, which can only be found in Hawaii. Another highlight is the opportunity to hike through the park's diverse ecosystems, including subalpine forests and desert-like cinder cones.
The Home of Franklin D. Roosevelt National Historic Site
The Franklin D. Roosevelt National Historic Site in Hyde Park New York
The Home of Franklin D. Roosevelt National Historic Site is located in New York state and is the former home of the 32nd President of the United States, Franklin D. Roosevelt. One of the highlights of this park is the chance to tour the Roosevelt family home, which has been preserved to look just as it did when the Roosevelts lived there. Another highlight is the opportunity to learn about FDR's life and accomplishments through exhibits and interactive displays.
Harpers Ferry National Historical Park

Harpers Ferry National Historical Park is in West Virginia and is known for its role in American history. One of the highlights of this park is the chance to visit the Armory and Arsenal. It played a key role in arming and equipping the Union army during the Civil War. Another highlight is the opportunity to take a guided tour of the town. It was founded in 1747 and has a rich history of industrialization and abolition.
Big Bend National Park

Of all the 63 National parks in the United States, Big Bend would probably be the one that I have spent the most time in. Big Bend National Park is located in far West Texas where night skies are dark as coal and rivers carve temple-like canyons in ancient limestone. The park is named for the bend in the Rio Grande River. One of the highlights of this park is the opportunity to go rafting or kayaking in the Rio Grande. Another highlight is the chance to see a variety of wildlife, including javelinas, roadrunners, and rattlesnakes.
San Antonio Missions National Historical Park

San Antonio Missions National Historical Park is located in Texas and is home to four Spanish colonial missions that were established in the 18th century. One of the highlights of this park is the chance to visit Mission San Jose. It's known for its beautiful stonework and historic gardens. Another highlight is the Alamo, an important symbol of Texas independence and a place to learn about the history of the missions and the role they played for over 300 years in the development of the region.
The National Park Service (NPS)
We wouldn't have amazing places like Big Bend or the home of FDR if it wasn't for the National Park Service. The NPS was established in 1916 and is headquartered in Washington, D.C.
Whether it's the smallest national park, Hot Springs National Park in Arkansas or one of the newest national parks like Ocmulgee Mounds National Historical Park in Georgia, or the largest national park Wrangell-St. Elias National Park & Preserve in Alaska, The NPS mission is the same: "preserve unimpaired the natural and cultural resources and values of the national park system for the enjoyment, education, and inspiration of this and future generations."
As an agency of the United States federal government, they are responsible for managing and preserving a collection of 425 national parks, monuments, and other natural and cultural resources. These gems cover more than 85 million acres in all 50 states, the District of Columbia, and US territories. Because no two places are alike, they are hard to categorize. This is why the terms used to describe these national treasures are sometimes confusing.
Here, we'll break down the different types of places managed in the national park system by the NPS and provide a few examples of each.

National parks are areas that have been designated by the United States government as protected land. These 63 national treasures are usually chosen for their natural beauty, unique geological features, or historical significance. Some of the most popular national parks include:
- Yellowstone National Park in Idaho, Montana, and Wyoming – At Yellowstone National Park you can embark on a journey through Yellowstone's vast wilderness. Geysers erupt with nature's fury. Wildlife roams freely across the rugged landscape. The beauty of the world's first national park unfolds in a symphony of awe-inspiring vistas and serene, starlit nights.
- Grand Canyon National Park in Arizona – At Grand Canyon National Park visitors can stand on the edge of the Grand Canyon's timeless grandeur. Colorful stratum tells a story millions of years old. This vast, majestic chasm beckons adventurers and dreamers alike to ponder the Earth's magnificent splendor.
- Yosemite National Park in California – In Yosemite National Park an explorer gets to wander through Yosemite's enchanting realm, where granite monoliths like El Capitan and Half Dome rise as nature's cathedrals. Waterfalls cascade with thunderous applause, and meadows and forests offer a tranquil retreat from the modern world.
- Sequoia National Park in California – In the land of giants, Sequoia National Park stands supreme. A place where the world's largest trees reach for the skies, creating a living cathedral and a humbling reminder of nature's enduring power and grace.
- Glacier National Park in Montana – Glacier National Park is a realm where the remnants of the Ice Age still sculpt the land. Rugged peaks and reflective lakes whisper tales of ancient times, inviting explorers to witness the raw beauty of a landscape carved by glaciers.

The most significant category of national parks are national monuments. In general, smaller than those outlined above, the 84 members of this category are usually designated as being aimed towards conserving natural, historical, and cultural resources. These include prehistoric camping grounds, secluded campsites, and stunning natural wonders. Some of the most popular national monuments are:
- Lava Bed National Monument in California – Lava Bed National Monument beckons the adventurous to its labyrinth of lava-hole caves. Shadows play on ancient rock and every turn invites discovery in the subterranean wilds.
- Petroglyph National Monument in New Mexico – Nearly 25,000 sculptures etched into volcanic rocks by ancestral Pueblo peoples enchant and mystify visitors to Petroglyph National Monument
- Devil's Tower National Monument in Wyoming – The Devil's Tower National Monument rises solemnly above the rolling prairie. It's a monolithic testament to Earth's volcanic past and inspires awe as America's first national monument.
- Muir Woods National Monument in California – You will find a sanctuary of serenity among the towering redwoods in Muir Woods National Monument. The quiet grandeur of ancient groves whispers the secrets of millennia in the cool, mist-laden air.

NASA helps launch Angry Birds Space game
Looking for ways to attract new audiences to its space and technology mission a year ago, NASA saw a prime opportunity to fly with some hugely popular birds.
And now the results of NASA's innovative collaboration with mobile game company Rovio Entertainment is approaching lift-off: the Angry Birds Space game created by Rovio with NASA's cooperation debuts on March 22.
Angry Birds is one of the most popular mobile games ever, with the company claiming more than 500 million downloads in two years. Originally created on iPhone, it is also available for Android and other devices. In the game, stylized cartoon birds are launched to destroy pigs.
"The value [of the collaboration] for NASA is in getting people excited about science and space technology," Bob Jacobs, a NASA spokesman, told Federal Computer Week on March 13. 'This could be an important tool to reach new communities. We saw the possibility of reaching a very different audience through a gaming platform," Jacobs said.
In the original game, the player launches the angry birds with a catapult to destroy the structures in which the pigs are hiding. The game reflects the laws of physics, so the player can change the angle and power of the catapult to change the trajectory of the bird.
The new space version of the game applies the laws of physics that exist in outer space. Rovio designers met with NASA engineers to develop ways to demonstrate zero gravity principles in movements within the game. The game also contains a permanent Web link to a NASA website on zero gravity, also known as microgravity.
The collaboration is generating a lot of interest. A jointly-produced video featuring NASA astronaut Don Pettit at the International Space Station has already received more than 4 million views on YouTube. In the video, Pettit demonstrates zero gravity principles in action with a stuffed bird resembling the Angry Red Bird character.
Rovio and NASA debuted the introductory video on March 8 at the South by Southwest conference in Austin, Tex. Pettit can be seen in the video talking about gravity while floating around the station and shooting one of the stuffed birds down a tunnel with the help of a slingshot.
It all started with a tweet
The project started a year ago when Jacobs noticed several tweets mentioning NASA and Angry Birds. "NASA launched a man to the moon. We launch birds into pigs," read a tweet from game consultant George Bray.
There also were tweets circulating about smart phones today allegedly having more computing power than NASA computers back in the 1960s, Jacobs recalled.
Jacobs responded through the _USER_ Twitter account he manages. "Hey, RovioMobile, our computers are a bit better than they were in '69. We might be able to help you launch birds if you can find a pig in space," Jacobs tweeted on March 27, 2011.
Rovio also responded, and a conversation began. "It started with a tweet," Jacobs said. "It sparked a lot of light bulbs going off in people's minds."
The collaboration took off from there, with NASA and Rovio signing a "Space Act Agreement" outlining the terms of the collaboration with Rovio, which is from Finland. The federal agency has many such agreements in which it cooperates with private sector projects, Jacobs said. For example, NASA previously had signed an agreement with Paramount Pictures for allowing the filming of a Transformers movie at the Kennedy Space Center. All such agreements are vetted by NASA management to ensure they comply with regulations.
One of the initial fruits of the NASA-Rovio effort was that a version of Angry Birds released in 2011 had an "outer space" level embedded in it. Rovio debuted that version to coincide with the final space station launch, and the company distributed tee-shirts and other publicity materials.
There are no financial terms in the agreement with Rovio, Jacobs said. NASA has no mechanism to receive funding for such efforts, he added.
Jacobs said the collaboration has been successful, because the goal is to reach new communities, including millions of people likely to play Angry Birds Space.
"We see it as a mutually beneficial relationship that allows us to get NASA mission information into the game," Jacobs said. But he acknowledged that measuring the success of the endeavor might be a bit tricky.
For example, Rovio's YouTube video on the NASA Angry Birds Space announcement has received more than 4 million views. Meanwhile, the NASATelevision version of the introductory video has received only about 38,000 views.
On the other hand, Jacobs said many people have tweeted about, and shared links to, both videos on social websites including Facebook, Google+ and Twitter. NASA is gaining value from that sharing even when people view the video at Rovio's YouTube page rather than NASA's, he asserted, because the people are being exposed to the same principles of science and technology regardless.
"Having a bird and pigs in space are fun and cool ideas," Jacobs said. "We are seeing communities getting excited about it and sharing the information."

 1. How long have you two been going out?
 2. We've gone out for two months now.
She reciprocated
When you reciprocate something, that means you do something in return for something someone did for you. For example, if someone gives you a gift, you can reciprocate by giving them a gift back. Here are some samples:
 1. In Asia, if someone bows to you, you should reciprocate and bow back.
 2. She cooked me dinner last week, so I reciprocated by buying her lunch.

That's funny you bring that up.
When you bring something up, that means you mention or talk about something for discussion. Here are some examples:
 1. The boss brought up the topic of the recent policy change.
 2. I never bring up serious issues at the dinner table.
making out (make out)
I see couples making out in public.
When two people'make out' that means they kiss for a long time. When people make out they are often sitting down and only kissing each other and not talking. Making out is something only young people usually do. Notice the following:
 1. The two teens were making out in the park. It was embarrassing.
 2. Have you made out with your new boyfriend yet?
Why don't you get a room?
This phrase 'Why don't you get a room?' is used as a joke to let two people ( or lovers ) know that their affection is obvious to other people and people feel a little uncomfortable and that they should 'get a room' so they can have some privacy.


System Administration Guide: Security Services
ProcedureHow to Add an Audit Class
When you create your own audit class, you can place into it just those audit events that you want to audit for your site. When you add the class on one system, you should copy the change to all systems that are being audited.
 1. Assume the Primary Administrator role, or become superuser.
 2. (Optional) Save a backup copy of the audit_class file.
 # cp /etc/security/audit_class /etc/security/audit_class.orig
 3. Add new entries to the audit_class file.
 Each entry has the following format:
 Identifies number as hexadecimal.
 Defines the unique audit class mask.
 Defines the letter name of the audit class.
 Defines the descriptive name of the audit class.
 The entry must be unique in the file. Do not use existing audit class masks.
Example 30–10 Creating a New Audit Class
This example creates a class to hold a small set of audit events. The added entry to the audit_class file is as follows:
0x10000000:pf:profile command
The entry creates a new audit class that is called pf. Example 30–11 populates the new audit class.
If you have customized the audit_class file, make sure that any modifications to audit_user are consistent with the new audit classes. Errors occur when the audit classes in audit_user are not a subset of the audit_class database.

Why Should I Go?
Built into the mountainside on the opposite side of the river across the Pudu Bridge from Tianxiang Village in Taroko National Park, the Xiangde Temple is a Buddhist temple from which visitors can enjoy a bird-eye view of Tianxiang and the surrounding area.
This temple is known for having the world's highest-elevated statue of Ksitigarbha (地藏), a bodhisattva revered by East Asians for protecting those in hell (那落迦), as he has vowed not to attain buddhahood until all beings in all hells have been freed. He is generally depicted as a Buddhist monk with a bald head and halo carrying a staff with a Cintāmaṇi jewel at the top (如意寶珠, similar to a philosopher's stone) to light the dark and force open the gates of hell.
Completed in 1968, the main hall is also surrounded by the Tianfeng Pagoda and a white-robed Guanyin statue.
About halfway up the walk is a merchant area selling local tea and snacks.

The SD will always be equal to or larger than the mean error, but usually not too far off. For a normal distribution, the SD is 25.3% higher than the mean error, I think).
The statistical Pythagorean Theorem, then, says that if you have two independent variables, A and B, then
SD(A+B)^2 = SD(A)^2 + SD(B)^2
This is really important... I learned it in the first statistics course I took, but I finished my entire statistics degree without realizing just how important it was, and how it makes certain regression results work. I searched the internet, and I only found one page that talks about it: it's a professor from Cornell calling it "the second most important theorem" in statistics. He's right... it really is amazing, and useful, that it all works out.
In the three dice case, the Pythagorean relationship meant that each die reduced the variance by the same amount, 2.92 out of 8.75 total. That allows statisticians to say, "The blue die explains one-third of the variance. The red die explains one-third of the variance. And the green die explains one-third of the variance. Therefore, together, the three dice explain 100% of the total variance."
Because it works out so neatly, it means statisticians are going to like to talk in variances, in squares of errors instead of just errors. That's because they can just add them up, which they couldn't do if they didn't square them first.
And that's what r-squared is all about.
Let's suppose you actually ran an experiment. You got someone to run 1,000 rolls of three dice each, and report to you (a) the total of the three dice, and (b) the number on the blue die. He reports back to you with 1,000 lines like this:
Total was 13; blue die was 4
Total was 11; blue die was 6
Total was 08; blue die was 1
Total was 17; blue die was 6
With those 1,000 lines, you run a univariate regression, to try to predict the total from just the blue die. The regression equation might wind up looking like this (which I made up):
Predicted total = 6.97 + (1.012 * blue die)
(The coefficients should "really" be 7 and 1.000, but they won't be exact because of random variation in the rolls of the green and red dice.)
And the regression software will spit out that the r-squared is approximately 0.33 -- meaning, the mean square error was reduced by approximately 1/3, when you change your guess from the average (around 10.5), to "6.97 + (1.012* blue die)".
That is: "the blue die explains 33% of the variance."
This makes perfect sense. But, as I argued in my 2006 post -- and others -- the figure 33 percent is limited in its practical application. Because, in real life, you're normally not concerned about squared errors -- you're concerned about actual errors.
Suppose you can't perfectly estimate how many customers your restaurant will have. Sometimes, you order too many lobsters, and you have to throw out the extras, at a cost of $10 each. Sometimes, you order too few, and you have to turn away customers, which again costs you $10 each. Suppose the SD of the discrepancy is 10 lobsters a day.
If a statistician comes along and says he can reduce your error by 50% of the variance, what does that really mean to you? Well, your squared error was 100 square lobsters. The statistician can reduce it to 50 square lobsters. The square root of that is about 7 lobsters. So, even though the statistician is claiming to reduce your error by half... in practical terms, he's only reducing it from 10 lobsters to 7. That's an improvement of 30 percent, not 50 percent, since your monetary loss is proportional to the number of lobsters, not the number of square lobsters.
The r-squared of 50% is something that's meaningful to statisticians in some ways, but not always that meaningful to people in real life.
Statements like "the model explains 50% of the variance" are useful in certain specific ways, that I'll talk about in a future post... but it usually makes more sense, in my opinion, to think about things in lobsters, rather than in square lobsters.

From the 2 April 1999 pages of Science Magazine
COPENHAGEN--A bitter row has broken out at the University of Copenhagen, which has been forced to cut its scientific staff to close a yawning budget gap. The university science department decided in January that, instead of assessing who were its least productive researchers and firing them, it would simply not fill any junior tenured positions that became vacant--in effect blocking the career path of young tenure-track researchers. As the consequences of that policy have begun to bite, aspiring young scientists say they now have little prospect of advancement and a whole generation of young researchers will either have to leave academic science or pursue a career abroad. "There is an atmosphere of hopelessness among students and postdocs whose possibilities for embarking on an academic career at the university now seem extremely limited," says plant molecular biologist Lars Østergaard, a postdoctoral fellow.
The crisis was precipitated late last year when the Danish government cut overall funding to Denmark's five universities. The science department at Copenhagen--the country's largest--was hit especially hard because it was already running a budget deficit. Forced to cut 15% of the tenured science positions--which translates into 70 people--the administration eliminated about 12 posts by offering early retirement to older faculty members and will cut the rest over time by not filling junior positions. "[It's] outrageous to prevent the necessary staff renewal and infusion of new ideas by forcing out young, talented, tenure-track scientists," says molecular biologist Olaf Nielsen, an associate professor.
The new policy is likely to exacerbate a simmering age problem in Danish universities. During the 1960s and '70s, the university system expanded rapidly and a large number of tenured positions were created. That generation of scientists is now approaching retirement age. "There will be an acute need for replacements when 30% to 40% of the currently tenured staff retire in 5 to 10 years," says associate professor of zoology Peter Arctander. "But because of what is happening now, there will be a lack of qualified young scientists."
Dean of science Henrik Jeppesen defends the policy. Although "it is sad that a number of young researchers have to leave," he says, "it would have created a very bad atmosphere to fire faculty members who have worked here for many years." This view is supported by university president Kjeld Møllgaard, who says it would be "an unfair personnel policy to simply get rid of the least productive as if it were a horse race." Jeppesen and Møllgaard both acknowledge, however, that the reaction of Denmark's powerful unions was a consideration. Per Clausen, president of the academics' union, the Magisterforeningen, says: "In principle we regard the science department's handling of the situation as the only proper response, but at the same time it is clear that blocking staff renewal will badly hurt the university and its research."
Indeed, research is already hurting. Several research groups have been reduced to the point that ongoing projects have effectively come to a halt. For example, one group in the department of genetics investigating the silencing of chromatin has been shut down after 4 years of successful work because the tenure of its leading assistant professor has been canceled. Science teaching will also be seriously hit, because courses are largely taught by assistant professors and junior associate professors. Leif Søndergaard, an associate professor of genetics, says that "because of the cuts, many courses will no longer be offered every year and others will be generating waiting lists."
Young researchers are now beginning to make their voices heard. Østergaard has sent a highly critical letter, signed by 90% of the graduate students and postdocs in the department of molecular biology, to the Copenhagen University Journal. Among other things Østergaard describes a widespread feeling that "the university is shooting itself in the foot by not identifying and getting rid of those researchers whose scientific contribution is minimal."

Pathology dictionary
Negative for malignancy
What does negative for malignancy mean?
Negative for malignancy means that no cancer cells were seen when the tissue sample was examined under the microscope. Pathologists use the word malignant to describe cancers.
This result is typically used when only a small sample of tissue is sent for examination under the microscope. This kind of sample could be a biopsy, fine needle aspiration, or Pap smear.
Your pathologist can only provide a diagnosis based on the tissue sample sent for examination. For that reason, negative for malignancy only means that no cancer cells were seen in the small sample examined. If your doctor is still concerned that a cancer may be present, they may recommend performing a second procedure to provide the pathologist with more tissue to examine under the microscope.
The opposite of negative for malignancy is positive for malignancy.

f:RdR≥0 is log-concave if log(f) is concave (and the domain of log(f) is convex).
Theorem: For all σ on the sphere Sd-1 and r∈R, gσ(r) := ∫σ.x=rf(x)dS(x) is a log-concave function of r. (Note: g, as a function of σ and r, is the Radon transform of f.)
Question: does this characterize log-concavity? That is, if gσ(r) is log-concave as a function of r for all σ, is f log-concave?

If I understand the question correctly, I think the answer is no.
Start with the following : if f is the indicator function of the unit ball, then the function g(r) is strictly log-concave close to 0 (this function does not depend on theta).
Now, let h be the indicator function of the ball of radius r<1. Then f-epsilon.h is never log-concave for any epsilon>0, and its Radon transform (which again is independent of theta) remains log-concave is epsilon is small enough.
(this is especially easy to see in dimension 2, in which case the Radon transforms of both f and h are second-degree polynomials on their support)

Great! Such a simple example, too. – Darsh Ranjan Oct 23 '09 at 1:28
The following answer exploits a wider context, where non-negative functions $f$, viewed as densities of absolutely continuous measures $f(x)dx$, are replaced by non-negative measures $\mu$. Because a concave function unbounded from above is $\equiv+\infty$, a log-concave measure $\mu$ is naturally an absolutely continuous measure with log-concave density.
Therefore the Lebesgue measure over the $2$-dimensional sphere $S^2$ is not log-concave over ${\mathbb R}^3$. Nevertheless, its Radon transform in a direction $\sigma$ is $$g_\sigma=2\pi\chi_{(-1,1)},$$ which is log-concave for every $\sigma$.

I like this example a lot, since a uniform measure on a sphere is far from log-concave. (And apparently I had never computed its Radon transform.) – Darsh Ranjan Sep 15 '10 at 0:18

When uploading images to the media library, WordPress will automatically generate several thumbnails so that a more optimized image size can be used.
Since different themes and plugins will often use different sizes, you might need to periodically regenerate your those resized images. In this article, we'll show you how to regenerate your image thumbnails using WP-CLI.
Regenerating All Thumbnails
To regenerate all thumbnails for all images inside your WordPress media library, you can use the following command:
wp media regenerate --yes
Once the command is run, all thumbnails for all images will be regenerated. Of course, if you have a large number of images inside your media library, it might take some extra time to run through them all.
Regenerating Missing Thumbnails
What if you updated your theme to add an additional image size but don't want to regenerate the thumbnails that already exist? You can regenerate thumbnails for only the missing image sizes using the --only-missing option like this:
wp media regenerate --only-missing
Regenerating Thumbnails for Specific Images
If you want to regenerate thumbnails for a specific image, you can specify it by including the attachment ID after the command like this:
wp media regenerate 123
To regenerate thumbnails for multiple specified attachment IDs, just add them to the command like the following example:
wp media regenerate 123 456 789
Keeping Old Thumbnail Sizes
When regenerating your WordPress media library image thumbnails, the default behavior is to delete the old thumbnails. If you want to keep them, you can use the --skip-delete option:
wp media regenerate --skip-delete
Regenerating Specific Thumbnail Sizes
In addition to being able to specify a specific image to regenerate thumbnails for, you can also define a specific thumbnail size to regenerate. To regenerate a specific size, use the --image_size option with the name of your thumbnail size as the value like in the following example:
wp media regenerate --image_size=large

Union councils of Pakistan
From Wikipedia, the free encyclopedia
Jump to: navigation, search
A sherwan or union council in Pakistan is an elected local government body consisting of 21 councillors, and headed by a nazim now called Chairman (which is equivalent to a mayor) and a naib nazim now called Vice Chairman (deputy). Union councils are the fifth tier of government in Pakistan and are often known as Village Councils in Khyber Pakhtunkhwa. A village council usually comprises a large village and surrounding areas, often including nearby small villages. The term Union or Village Council may be used for localities that are part of cities.
Headed by a union nazim, each union council has 13 elected members or councillors. In addition to four male and two female members elected directly, there are two male and two female representatives of the labour, a minority member, a union nazim and his deputy known as union naib nazim. Beside elected members, there are several government employees and functionaries in every union council, who report to the secretary of the union council. The latter is a civil servant appointed by the state.
The territory of a union council or village council is usually part of a tehsil (a district subdivision). Less commonly, a union council may be part of a city district.[1]


termed "impact analysis" is more detailed and costly, but also much more certain.
Table 8. MOC change impact pre-screening attributes.
From a best practice perspective, it's critical that change impact pre-screening differ dramatically from detailed impact analysis. Otherwise, pre-screening (which is supposed to be a 1 minute operation) will morph into its own business process and slow down the entire MOC initiation process. Screening questions should be designed so that all the screening questions should normally be answerable by one person, typically the initiator.
Change Impact Pre-Screening Impact Analysis
Process safety screening Is this a change to inventory of material? PHA to assess impact of inventory change.
Is there a change in the potential for personnel exposure? PHA to assess impact of personnel exposure change.
Environmental screening Is there a potential for a change in community effects? Analysis to assess impacts on community.
Does the change add a new air emission source of any pollutant? Analysis to assess impact of new emission source.
Financial screening Rough Order of Magnitude cost, say, ±100% More accurate cost estimate, say, ±20%
Table 9. Impact pre-screening vs. analysis.
Pre-screening Process Safety Risks
Pre-screening is often used to determine the following:
 - what kind of impact analyses will be performed during the Impact Analysis state: HAZOP, what-if, etc.?
 - does the change involve a topic where the company has received a prior citation? The intent is to identify these cases early in order to avoid a "willful negligence" citation.
Pre-screening Environmental Risks
Pre-screening is often used to identify the following:
 - does the change have the potential to create a situation which will cause permit limits to be exceeded? If so, then the Environmental group will demand immediate input on the change proposal.
Pre-screening Costs
Pre-screening is often used to determine the following:
 - if this is a discretionary change, does the change cause a budget limit to be exceeded? The person, paying for the change, may not actually have sufficient funds to allow it to proceed.
The cost attribute captures this information. But costs are not well known this early in the change process, so it's necessary to indicate the cost accuracy, e.g. ± 100%.
Most of the pre-screening attributes, but particularly costs, can be interpreted in multiple ways. Does the cost attribute represent just the material costs? material plus labor? or, some other variation? Some guidance on the form would be helpful, otherwise this data will not be provided in a consistent manner.
Additional information, that the initiator believes is important and/or relevant, can be put into the comments section, see Table 10.
Table 10. MOC comments.
This is "a" mechanism for capturing commentary during a change. The benefit of comments is that this typically appears on the front page of an MOC.
In electronic implementations, comments are also possible and desirable. However, other techniques, like Wikis, threaded discussions, "team sites", and so on, may provide the same benefits as a comments field.

Any responsible pet owner knows that owning pets, especially dogs, is a big responsibility. However, in Costa Rica there is a big dog dilemma.
With thousands of puppy mills, so-called breeders, and pet shops throughout the island nation, dogs are everywhere, yet sadly, an estimated one million dogs are released to the streets each year by owners no longer able to or perhaps no longer want to care for them.
Just as in many other countries, dogs in Costa Rica are used as status symbols, given as gifts to children and loved ones, and brought in as companions. However, when the novelty wears off and the dogs grow, often without proper training or space to live, they can become more work than their owners think they are worth, and the dogs are thrown out into the street.
Dogs once welcomed into homes are just as quickly left to fend for themselves on the streets and even given a new name, "callejeros" or "street dogs".
Animals rescue workers have long urged residents to carefully consider bringing a pet into their home, and to never buy from pet stores, as many of the dogs come from puppy mills that continue to mistreat and over breed dogs, that as many now see just wind up on the streets.
During a recent National Geographic Channel documentary, "Dog Whisperer" Cesar Milan traveled to with Last Chance for Animals (LCA) to take a look inside puppy mills. Lat year, the Cesar Milan Foundation and LCA teamed up to create a PSA in Costa Rica tilted, "Adopt, Don't Shop."

We can definitely say one thing about the electronics industry – thanks to it, adhesive tapes are at our side all the time. For example, in our smartphone. According to a 2015 survey in Germany, 17 percent of surveyed users installed over 31 apps on their mobile phone. What they do not know was that the number of tesa adhesive tapes installed in their smartphone is around 45.
While users swipe across their touchscreen, oblivious to them, one level below, each individual special adhesive tape is doing its work layer by layer: adhesive tapes hold the layers of the screen together (unnoticed, since they are extremely transparent and optically clear); they block the light inside and direct it to where it should go, divert heat so that the processors do not burn out, and they cushion the impact if the device with its 31 apps and 45 adhesive tapes falls to the floor. In the process, adhesive tapes are so inconspicuous and thin that they can be used for any design. Incidentally, tapes also play a role in LED televisions, laptops and digital cameras and in navigation and communication systems for cars.


Mask Guidelines

From: Diocesan Communications
Mask Guidelines in Light of CDC, Governor's Announcements
LEXINGTON — In light of Gov. Beshear's Executive Order of May 13 lifting the mask mandate for persons fully vaccinated against COVID-19, parishes and missions of the diocese should observe the following protocols at Mass, beginning immediately:
1. Social distancing rules remain in place (six feet apart except for immediate family).
2. Masks are not required for people who are fully vaccinated, per CDC definition (see below).
3. Those who attend Mass but are not fully vaccinated must continue to mask, and since the new CDC announcements and governor's directives make it impossible to enforce mask restriction, all are strongly encouraged to get vaccinated as soon as possible.
Per the CDC, a person is considered fully vaccinated two weeks after receiving the second dose in a two-dose series, such as the Pfizer or Moderna vaccine, or two weeks after a single-dose vaccine, such as Johnson & Johnson. A person who doesn't meet these requirements, regardless of age, is not fully vaccinated and should continue taking all precautions until fully vaccinated.

Although C.K.G. Billings' mansion burned to the ground in the 1920s, Rockefeller salvaged the remaining structure and incorporated it into the park design. The massive structure which survived the fire is known as the Billings Arcade – a 50-foot arched structure which was the original driveway that meanders up the hill to the estate. It is part of a 1,600 foot long brick driveway that leads to the mansion through the Billings gatehouse – another surviving fragment renamed as the Fort Tryon Cottage.

Category:Lonar crater lake
Lonar Lake, which was created by a meteor hitting the Earth, is a saltwater lake in Buldhana district, Maharashtra, India. The crater thereby formed is the only en:hypervelocity meteoritic impact crater on basalt rock. A lake that evolved in the resulting basaltic rock formation, is both saline and alkaline in nature. Geologists, ecologists, archaeologists, naturalists and astronomers have reported several studies on the various aspects of this crater lake ecosystem. The crater's age is estimated to be 52,000 ± 6,000 years (Pleistocene). It is the second largest impact crater in basaltic rock and is partially filled by a salt water lake. 19°58′36″N 76°30′30″E / 19.97667°N 76.50833°E / 19.97667; 76.50833

Interesting (to me!) that this is an established result, since without the co-compactness assumption the conclusion fails: an irrational winding in SO(2) combined with the one-dimensional discrete subgroup of translations immediately gives a non-discrete image in SO(2). – paul garrett Mar 7 '13 at 0:47
Professor Garrett, I do not understand your remark. If I have an element of the form $(v,r)$ in the semi-direct product of ${\mathbb R}^2$ with $SO(2)$, where $r$ is an irrational rotation, there is no guarantee that itw powers (vector component) is discrete: the $n$-th power vector component is of the form $(1+r+\cdots +r^{n-1})v$, which can well converge. – Aakumadula Mar 7 '13 at 1:16
Of course, you can take $v\in {\mathbb R}^n$ $n\geq 3$ which is fixed by the rotation $r$, in which case you get a discrete group. When you assume "co-compactness", the vector parts are sufficiently many that the rotation parts do not always fix the vector part. – Aakumadula Mar 7 '13 at 1:24

The Prirazlomnaya oil-producing platform owned by Gazprom Neft company is currently the first Russian hydrocarbon production project on the Arctic shelf. Since it was designed for the Arctic region, the platform can be used in extreme weather conditions and withstand maximum ice loads, which makes it a unique and technically complex project.
The first loading of oil from the platform to an arctic tanker was carried out in April 2014, while by 2021 the platform operator is planning to increase the rate of oil production up to five million tons. However, gained experience revealed that a marine transport system for oil export and delivery of supply cargoes to and from the platform should be improved. Taking into account the variability of the Arctic sea meteorological and ice conditions, it was necessary to increase the effectiveness, survivability, and safety of the maritime transport system.
To meet this challenge, in 2016, the experts from Krylov State Research Centre studied a transport system for the Prirazlomnaya platform, for the period up to the year 2038, using a detailed simulation model developed in the AnyLogic environment.
The marine transport system includes the platform itself, two shuttle tankers, and several offshore supply vessels. Despite the apparent simplicity, the transport system is quite specific due to several important features:
- Each of the four platform's cargo terminals has its operational limitations due to meteorological and ice conditions characterized by high variability.
- Since oil is loaded to shuttle tankers directly from the platform, together with the processing of supply cargoes, vessels of different types have to compete with each other for weather windows of terminals.
- Сargo flows of oil and supplies vary significantly both in their quantity and structure.
- The capacity of oil tanks and supply storages on the platform is limited, which is why just-in-time organization of supply and oil export processes is needed, without creating dead stocks of cargoes.
By using agent-based and discrete event modeling in the AnyLogic environment, Krylov Centre experts created a simulation model of the transport system. The model allowed them to consider all of the important technical characteristics, along with physical and logistic processes of the real system. The vessel operations between the Prirazlomnaya platform and the Murmansk port were modeled in the GIS environment, taking into account natural conditions on the route.
Several interacting computational processes were represented as separate simulation algorithms in the general simulation model:
- Cargo transportation, i.e. vessel operation according to the voyage plan.
- Generation of weather conditions and determination of cargo terminals' accessibility.
- Modeling of dynamics of filling and discharging of platform storages.
- Modeling of ship operations near the platform.
- Auxiliary stochastic processes and events, such as the addition and removal of vessels from operation, the arrival of a helicopter, etc.
To describe simultaneous accessibility of the four cargo terminals while considering their limitations, the experts created the stochastic generator of natural conditions at the area of platform location. The generator enabled them to model a time series of 15 environmental parameters, such as speed and direction of wind and current, height of waves, cloudiness, air temperature, visibility, and others, taking into account the interrelation of different parameters. For example, wind and current have an impact on speed and direction of an ice drift.
The model also described the complicated logic of multiple ship approaches to the platform, that are affected by varied weather conditions. The experts added to the model the ability to conduct consecutive operations of various types of supply cargoes, as well as unscheduled interruption of operations due to weather window termination, transition of the vessel to another terminal, or departure of the vessel beyond the three-mile border zone of the platform. Also, the model included an algorithm for a local decrease of oil production in case of a risk of a full filling of oil storage.
The following data served as input parameters: planned cargo flows of crude oil and supplies for the period until 2038, tactical voyage plan of vessel operations generated using the optimization algorithm, and average duration of ship operations.
The Krylov Centre experts analyzed eleven improving measures to increase the efficiency of the marine transport system of the platform. The list of measures included: putting into operation an additional shuttle tanker, increasing the speed of oil offloading, using an additional icebreaker, and other methods. The practical aim of the analysis was to increase the efficiency of the transport system in terms of the ratio of the cost and the achieved reduction in volumes of underproduced oil.
The volume of underproduced oil for the period from 2016 to 2038 served as the main efficiency criterion. This volume was calculated based on the number and duration of cases of reduction in volumes of oil production, which occur when storages are fully loaded and tankers cannot offload oil fast enough.
The obtained data helped the experts discover that the construction of a terminal or an additional oil storage shows an absolute effect, i.e. the absence of underproduced oil. However, the practical implementation of these measures proved to be costly and technologically complicated, which is why they were excluded from further consideration.
The simulation modeling allowed the experts to reveal that the expansion of accessibility of oil terminals has the highest positive effect on system efficiency of all the other measures. This can be achieved by implementing a range of technical measures, and by using the short weather windows for tanker cargo operations that allows for increasing the total duration of weather windows by 10-15%. However, the crucial point for system efficiency was not the total duration of accessibility periods, but the availability of a tanker to approach the platform at a desired moment of time.
The model enabled the experts to discover that putting an additional shuttle tanker into operation has no significant impact on system efficiency, because the bottleneck of the system is oil offloading under weather change, not the shortage of tankers.
The results of the study collected with the AnyLogic model helped the experts determine technical and operational characteristics for each improving measure and evaluate statistical distribution laws of all key parameters. The obtained data formed a basis for making managerial decisions at the top level of the Gazprom Neft Shelf Company.
Another project carried out by Krylov Centre experts for Gazprom Neft, with the help of simulation modeling, was the design of a maritime oil transportation system for the harsh ice environment.

Barresi seeking $2,000 raises for all Okla. teachers
Barresi 1
OKLAHOMA CITYThe state superintendent is now turning her attention to Oklahoma's teacher shortage.
Janet Barresi convened the first meeting of the Teacher Shortage Task Force Monday morning.
The group came up with a list of factors impacting the district's ability to recruit and retain the best teachers.
Among them were teacher salaries, strong competition in the private sector and border state competition for higher paying jobs.
Currently, a first-year teacher in Oklahoma makes about $31,600 per year.
That puts us in the bottom ten states in the country when it comes to starter salaries.
The average teacher's salary in our state is just over $44,000 per year.
Teachers in 46 other states make more money, including our neighbors to the south in Texas.
Teachers there make an average of more than $48,000.
Barresi is asking that each teacher receive a $2,000 raise, which would make the Sooner State more competitive with surrounding states like Arkansas, Missouri and Texas.
She says the extra money could be funded by tapping into surplus funds and reducing schools' administrative overhead.
The group will meet up three other times before the end of the year.


Medical Tourism in India
medical tourism in india
India is thriving as a new medical tourism destination across the globe. Medical tourists from international cross borders in search of advance and cost-effective medical treatment prefer India. It is the fact that many developed countries have a higher cost of treatment. Here, they get the latest medical technologies, high quality of healthcare service, with better recovery rates at nominal charges. Globalization, international trade, and medical advancement enhance healthcare tourism in the country. Let's take a look at the reasons why India has become a popular medical tourism destination:
Why do Patients Choose to Come to India for Their Treatment?
When a treatment goes along with the vacation, it is known as medical tourism. In collaboration with the tourism industry, the healthcare sector in India is working together to provide advanced treatment to people worldwide and give them a better environment for a speedy recovery.
Advantages of Healthcare Tourism in India
 - Affordable medical treatment for the life-threatening disease like cancer, tumor, organ transplant, and more
 - Skilled, experienced, and highly qualified doctors and medical staff
 - Advance healthcare facilities
 - No language obstacle
 - Affordable accommodation
The leading factor encouraging tourists seeking medical help from different countries to visit India is the low cost of treatment. Developed countries have lengthy and cumbersome vias and immigrant formalities. Moreover, hospitalization, treatment, medication, etc. cost much higher. Whereas, here it is comparatively easier to obtain a medical tourist visa and all sorts of advanced medical treatments are available in the leading hospitals. Healthcare providers are continually working towards making the treatment process more streamlined and efficient for foreign medical tourists.
What Role does Ayurveda play in Boosting Healthcare Tourism in India?
Ayurveda treatment is deeply rooted in Indian culture. The country has originated as one of the most important medical tourism hubs, and Ayurveda plays an important role. Medical tourism packages combined with several fun and fitness activities, tours, etc. to make it complete tourism material. Foreigners believe in Ayurveda, and they find India as the best place for ayurvedic or alternative treatments like AYUSH( Ayurveda, Unani, Sidha, and Homeopathy). They undergo several healing treatments as a combination of Ayurveda, yoga, acupuncture, herbal oil massage, and natural therapies. Often people prefer such therapies and treatments post-surgery. It helps in fast recovery and revival.
Kerela and other states have emerged as the Ayurveda and Yoga hubs in India. Foreign tourists from different countries come for rejuvenation. Benefits of alternate treatments:
 - Natural ways for the cure
 - No side effects
 - Treatment for stress and anxiety via natural means
 - Ayurveda helps cure Insomnia, improves metabolism
 - Cost-effective with sustainable recovery
So, as an Indian citizen, you should feel blessed that you are already in the safe hands as far as your health is concerned. However, whether it is allopathic or ayurvedic treatment, one thing that helps you to cover your treatment cost is health insurance. Care Health Insurance brings you Care- a comprehensive health insurance product that gives coverage for allopathic and alternative treatments.

The proposed method is designed for images whose gray levels vary continuously in space. The image model is based on a lattice of nodes corresponding to vertices of triangles in which the gray level of each pixel is produced by linear interpolation. A constraint on isoline gray levels is introduced to regularize the solution.

Focus Areas of Statewide Significance
What are Beginning with Habitat Focus Areas?
Beginning with Habitat (BwH) Focus Areas are natural areas of statewide ecological significance that contain unusually rich concentrations of at-risk species and habitats. These areas, identified by biologists from the Maine Natural Areas Program (MNAP), Maine Department of Inland Fisheries and Wildlife (MDIFW), Maine Department of Marine Resources (DMR), U.S. Fish and Wildlife Service (USFWS), The Nature Conservancy (TNC), Maine Audubon, and Maine Coast Heritage Trust (MCHT), support rare plants, animals, and natural communities, high quality common natural communities; significant wildlife habitats; and their intersections with large blocks of undeveloped habitat. BwH Focus Area boundaries are drawn based on the species and natural communities that occur within them and the supporting landscape conditions that contribute to the long-term viability of the species, habitats, and community types.
One or more of the following must be present before an area is considered a Candidate Focus Area (in most cases, two or more are present):
- Globally rare plant or animal
- 3 or more healthy populations of a rare plant species
- Any healthy population of a rare animal species
- Rare natural community
- Excellent example of a common natural community
- Good example of a common natural community and one or more high value wildlife habitats
- Large undeveloped block and at least one of the following: a good example of a common natural community OR high value wildlife habitat OR two or more healthy populations of a rare plant species
To date, collaborative efforts by state, federal, and conservation organization biologists have resulted in the designation of 140 Focus Areas (link to map) of statewide ecological significance. For a list of Beginning with Habitat Focus Areas and to find fact sheets about each area, visit the Focus Area Description website.
Why Designate Focus Areas?
It is hoped that the mapping of a BwH Focus Area will help to build regional awareness, and draw attention to the exceptional natural landscape conditions that result in a convergence of multiple resource occurrences. The resulting appreciation of these truly special places can then provide momentum to municipalities, land trusts, and regional initiatives focused on strategic approaches to conservation.
Are Other Areas Insignificant?
Areas that rise to the level of statewide ecological significance may not occur within the jurisdiction of every land trust or within the boundaries of every town. Strategic conservation planning is important at all levels and can be pursued to identify areas of local or regional significance as well. Although the frame of reference of BwH efforts has been a comprehensive analysis of Maine's organized territories, the criteria used in designating focus areas can be easily adapted to the local or regional perspective. BwH maps such as Map 2 (High Value Plant and Animal Habitats) and Map 3 (Undeveloped Habitat Blocks) offer a good starting point to identify unique locations rich in significant habitat feature convergence that can then be designated as local focus areas that serve as a starting point for developing your town's or land trusts conservation blueprint.
Strategies for Local Action:
- Incorporate Focus Areas into long-term plans for conservation. Towns and land trusts can work together on comprehensive and open space plans and capitalize on opportunities where goals coincide
- Identify property owners whose lands host significant natural features and investigate conservation options ranging from voluntary actions to fee purchase
- Become familiar with the rare plants, animals, and habitats and learn better how to manage them for long-term preservation
- Educate landowners and the general public about significant natural areas and create support for local conservation initiatives
- Cooperate with neighboring landowners and jurisdictions
- Incorporate Focus Areas in grant applications
- Work with state agencies to garner support for projects

REPORTING ENRICHMENT FORMS
Production reporting can be time-consuming. Our Reporting Enrichment Forms (REF) eliminates the need to spend hours filling in spreadsheets by capturing data automatically from web-based forms and your Fleet Management System. Managing business targets, shift handover notes and machine configurations has never been easier.
Example Use Cases
REF is a versatile tool which can be easily customised to meet your business needs. Example uses include:
Asset Groupings: Assigning multiple assets to a single piece of equipment - for example, a drill rig with multiple engines operating in a region under a single fleet manager. Aggregated reports can then be created based on these hierarchy levels as desired.
Recommended Actions: Creating action lists based on specific operating parameters. This helps to keep your fleet management organised, and in particular, can help less experienced personnel manage the fleet.
Asset Configurations: Adjusting equipment configurations such as tonnage capacity, enabling more realistic and meaningful reporting.
Production Targets: Setting up target production tonnes per shift to compare to actual tonnes produced, making clear where targets are and aren't being met.
Shift Notes: Adding comments to a shift to provide context for performance, allowing you to note factors such as adverse weather conditions, accidents and poor loading conditions
How it works
REF allows you to input data on-site targets, limits, grouped assets etc. into customisable web-based forms. The form-entered information is then captured in a database alongside data from your Fleet Management System and other automated sources. This allows you to easily generate reports through software such as SAP BusinessObjects. Multiple linked pages can be quickly generated through REF for each business use.

You must be an Insightly administrator to create a new rule.
Lead assignment rules automate the process of assigning leads as they are added to Insightly, making it easier on sales managers and teams to distribute leads evenly or according to specific criteria. You can choose to assign leads in a number of different ways, including:
- Geographic area, by selecting fields like Postal Code, State/Province, or City.
- Number of employees, by selecting the Employee Count field.
- Your own custom fields that you've set up in Insightly.
- Round robin, by selecting a team or multiple individuals to receive leads on a rotating basis.
You can use almost any lead field to set up a rule, and you can choose from many different matching criteria.
Creating a lead assignment rule
- Click the profile icon, and navigate to the System Settings > Lead Assignment Rules page.
- Click the Add Rule button.
- Enter a name for the rule that summarizes the criteria you'll be entering. In this example, we're assigning leads according to the state or province in their mailing addresses, so we're calling it "Assign by Region."
- Select which methods of entry the rule will apply to. These are the ways your leads are being entered into the CRM. Your options are:
- API - When leads are created automatically from sources outside of Insightly through our API.
- Web to Lead form - When leads are added from an Insightly-generated webform that you place on your website.
- Manually Added Leads - Leads entered by one of your users through their web browser or Insightly mobile app. This also includes copied leads, or contacts that are changed to leads.
- Select more than one of the above - You can apply the same rule to more than one entry method.
- Select none of the above - You can create rules that won't be applied to any of the entry methods above, but can be selected when you import leads.
While you can create more than one lead assignment rule, only one can be active for a particular entry method. In other words, you can set up a rule that applies to leads created from the Web to Lead form and are manually entered. But if you create another rule for manually-entered leads, the first rule you created will no longer apply to that entry type.
- Click the Save Rule button.
- The criteria section will now appear for your rule. This is where you tell Insightly which data to look for and whom to assign the matching leads to. To enter your first set of criteria, click the Add Criteria button.
- Select the field and an operator, then enter a value for the leads you want to match to. For each new filter, click the Add Filter Row link and select the AND or OR operator. Use AND to narrow the number of leads that will match, and use OR to broaden the list of matches with either the preceding value or the next value.
In this example, we're creating a set of criteria for a region of western U.S. states. We'll filter our leads by State/Province fields that are equal to CA OR NV OR AZ.
- When your criteria filters use both AND and OR Boolean operators, you'll need to organize them using the Filter Logic field to correctly match the leads. If you're not mixing AND and OR operators, skip this step.
- Select a team, a user, or multiple users. When a team or more than one user is selected, Insightly will assign the leads in a "round robin" fashion. That means the system will rotate the assignments through the group of users alphabetically by first name.
For example, for a three-person team: Lead #1 goes to user Adam Smith, Lead #2 to David Hume, and Lead #3 to Thomas Reid, then Lead #4 will go to Adam Smith and start the cycle again, evenly distributing the leads as they are added.
- Click the Save Criteria button.
- The rule will be updated and saved with your new criteria. Click the Add Criteria button to add your next set of criteria following steps 6 through 10. Continuing our example, we could add other regions for states in New England and the Southeast U.S.
- Click the bar to the left of an item to reorder the criteria, if necessary. Each entry will be executed sequentially, so if a new lead matches the first set of criteria, it will be assigned and the process will end. If it doesn't match the first, Insightly will check the second, then the third, etc. Place the criteria in an order that considers that logic.
It's a good idea to have the last set of criteria be broad enough to catch leads that will slip through all the other rules. For the regional example, we might have a criteria that says "if State/Province is empty, assign to the sales manager."
- Click the Save Rule button to save your changes.
- Now that your rule is set up, enter a test lead through each of the methods you've selected. If the lead isn't assigned properly, adjust your rules and criteria as necessary. (Don't forget to delete your test leads when you've finished testing.)
Testing the process will also help you catch criteria that may have been overlooked. This can be a bit of a logic puzzle at first, but you'll get the hang of it!


Diagnostics Guide

Running Diagnostic Commands
Use diagnostic commands to communicate with a running Oracle JRockit JVM process. These commands tell the JRockit JVM to for example print a heap report or a garbage collection activity report, or to turn on or off a specific verbose module. This chapter describes how to run diagnostic commands and lists the available commands. The following sections are included:
Diagnostic Commands Overview
Diagnostic commands help you communicate with a running JRockit JVM process. With these commands you can for example ask for a heap report or enable or disable a verbose module.
You can send diagnostic commands to a running JVM process in several ways:
You can enable or disable any diagnostic command using the system property -Djrockit.ctrlbreak.enable=, where name is the name of the diagnostic command. The following two handlers are disallowed by default and need to be turned on:
For example:
Using jrcmd
jrcmd is a command line tool included with the JRockit JDK you can use to send diagnostic commands to a running JVM process. This section provides a brief overview of jrcmd. It includes information on the following subjects:
How jrcmd Communicates with the JRockit JVM
jrcmd uses the JRIPC library, a small C library, to communicate with a running JRockit JVM process. JRIPC has the following basic functionality
How to Use jrcmd
To use jrcmd, simply enter it at the command line, with the appropriate parameters:
jrcmd [ []] [-l] [-f file] [-p] -h]
If the PID is 0, commands will be sent to all JRockit JVM processes. If no options are given, default is -p.
jrcmd Examples
Here are some examples of using jrcmd for:
Listing JRockit JVM Processes
Do the following to list all JRockit JVM processes running on the machine:
 1. Run jrcmd or jrcmd -p to list the running JRockit JVMs; for example:
 2. > jrcmd -P
 10064 Sleeper
 -Xverbose:memory -Xmx30m
 You will see the PID of the process (10064) and the program it is currently running (Sleeper) as well as the parameters used to start the JVM (-Xverbose:memory -Xmx30m).
Sending a Command to a Process
To send a command to the process you identified in Listing JRockit JVM Processes, do the following:
 1. Find the PID from Listing JRockit JVM Processes (10064)
 2. Enter jrcmd with that PID and the version command; for example:
 3. > jrcmd 10064 version
 This command sends the version command to the JRockit JVM. The response will be:
 Oracle WebLogic JRockit(R) Virtual Machine build 9.9.9-1.5.0-Jun 9 2004-13:52:53-, Native Threads, GC strategy: parallel
Sending Several Commands
You can create a file (just like the ctrlhandler.act file) with several commands and execute all of them. Use this procedure:
 1. Create a file called commands.txt with the following contents:
 - version
 - timestamp
 2. Execute the file with jrcmd; for example:
 3. > jrcmd 10064 -f commands.txt
 The system will respond:
 ==== Timestamp ==== uptime: 0 days, 00:05:04 time: Fri Jun 11 14:28:31 2004
 4. Use the PID 0 to send the commands to all running JRockit JVM processes.
Known Limitations of jrcmd
When using jrcmd, be aware of these limitations:
Ctrl-Break Handler
Another way you can run diagnostic commands is by pressing Ctrl-Break. When you press Ctrl-Break, the JRockit JVM will search for a file named ctrlhandler.act (see Listing 21-1) in your current working directory. If it doesn't find the file there, it will look in the directory containing the JVM. If it does not find this file there either, it will revert to displaying the normal thread dump. If it finds the file, it will read the file searching for command entries, each of which invoke the corresponding diagnostic command.
Listing 21-1 ctrlhandler.act File
set_filename filename=c:\output.txt append=true
print_object_summary increaseonly=true
print_threads nativestack=true
jrarecording filename=c:\myjra.xml time=120 nativesamples=true
verbosity set=memory,memdbg,codegen,opt,sampling filename="c:\output"
# ctrl-break-handler will stop reading the file after it finds
# the stop key-word
# version - print JRockit version
# print_threads - the normal thread dump that lists all the currently
# running threads and there state
# print_class_summary - prints a tree of the currently loaded classes
# print_utf8pool - print the internal utf8 pool
# print_object_summary - display info about how many objects of each
# type that are live currently and how much size
# they use. Also displays points to information
# jvmpi_datadump
# jvmpi_datareset
# jrarecording - starts a jrarecording
# verbosity - changes the verbosity level, not functional in ariane142_04
# start_management_server - starts a management server
# kill_management_server - shuts the management server down
# (the managementserver.jar has to be in the bootclasspath for
# these command to work)
In the ctrlhandler.act file, each command entry starts with a Ctrl-Break Handler name followed by the arguments to be passed to the Ctrl-Break Handler. The arguments should be on the property form (that is, name=value; for example, set_filename filename=c:\output.txt append=true). String, integer or boolean values are acceptable property types.
You can disable Ctrl-Break functionality by setting this command:
Available Diagnostic Commands
Table 21-1 lists the currently available diagnostic commands.
Table 21-1 Existing Ctrl-Break Handlers
set_filename filename= [append=true]
Set the file which all commands following this command will use for printing. You can have several set_filename commands in a file. It takes two arguments: filename and an optional append to specify if you want to append to the file or overwrite it. The default file is stderr, and to overwrite the file.
Prints a timestamp.
Prints the JRockit JVM version
print_threads [nativestack=true] [jvmmonitors=true]
Prints a normal thread dump.
 - nativestack=true will print C-level stacktraces as well as Java traces.
 - jvmmonitors=true will also print the JRockit JVM's internal native locks (those that are registered): status and wait queue, and with -XXnativeLockProfiling=true their profile stats (acquired/contended/tryfailed).
verbosity [args=] [filename=]
Change the verbosity level normally specified with -Xverbose. This handler does not work in R25.
Prints the command line used to start the JRockit JVM.
See the JRockit Memory Leak Detector User Guide (for JRockit Mission Control 1.0) or the Memory Leak Detector built-in help (for Oracle JRockit Mission Control 2.0 and later).
Print all loaded classes.
Print all UTF8 strings.
Print all memory the OS says the JRockit JVM process is holding onto, as well as what each subsystem thinks it is holding onto.
Note: This command applies only to versions of JRockit JVM R26.3 and earlier.
Cause an OutOfMemoryDiagnostics to be printed. If both set_filename and -Djrockit.oomdiagnostics.filename is set, the latter takes precedence.
This command is deprecated in the JRockit JVM R26.4. Use heap_diagnostics instead.
Cause a heap diagnostic to be printed. Output ends up on Ctrl-Break Handler output stream and does not take the property -Djrockit.oomdiagnostics.filename into consideration. This command applies only to versions of JRockit JVM R26.4 and later.
Prints out a report on the JVM's native memory allocation on the C-Heap. This is only supported if you are running with HEAP_TRACE defined.
Prints out a comprehensive summary of garbage collection activity so far during the run. In order to be able to dynamically print out the same information as -XgcReport would provide at the end of an application run, make sure to have the option flag -XgcReport in your start-up configuration, otherwise the correct measurements won't be performed.
jrarecording [filename=] [time=] [nativesamples=true]
Starts a JRA recording. For more information, please refer to Creating a JRA Recording with JRockit Mission Control 1.0
run_optfile [filename=]
Starts the management server. (Actually the listening socket that in turn starts servers whenever a connection is established). managementnserver.jar has to be in the boot classpath for this command to work.
Stops the management server. (Actually shuts down the listening socket.) The only reason it isn't named stop_management_server is that stop is a reserved keyword that stops parsing of the act file

I'm building an AST using ANTLR. I want to write a production that matches this string:
In my grammar file I have:
This works fine. I'm using my own adaptor to emit tree nodes. The rewrite rule used creates for me two nodes: one for NODE_VAR_REFERENCE and one for IDENT.
What I want to do is create only one node (for the NODE_VAR_REFERENCE token), and this node must have the IDENT token in its "token" field.
Is this possible using a rewrite rule? Thanks.

Well, to let IDENT be the token of the node NODE_VAR_REFERENCE would mean there isn't any NODE_VAR_REFERENCE at all. A token consists of a type (NODE_VAR_REFERENCE or IDENT) and some text this token matched. To let a tree node's token become IDENT would mean both the type and text would be that of IDENT (losing the NODE_VAR_REFERENCE token, or type).
What you probably mean is to have single node with type NODE_VAR_REFERENCE and the text of IDENT, in which case you could do something like this:

We show how a conceptually simple search operator called Optimal Reinsertion can be applied learning Bayesian Network structure from data. On each step we pick a node called the target. We delete all arcs entering or exiting the target. We then find, subject to some constraints, the globally optimal combination of in-arcs and out-arcs with which to reinsert it. The heart of the paper is a new algorithm called ORSearch which allows each optimal reinsertion step to be computed efficiently on large datasets. Our empirical results compare Optimal Reinsertion against a highly tuned implementation of multi-restart hill climbing. The results typically show one two orders of magnitude speed-up on a variety datasets. They usually show better final results, both in terms of BDEU score and in modeling future data drawn from the same distribution.

It used to be named Uleyan, derived from a mountain located at the heart of the island. Later, it was changed to Matangal, also named after Mt. Matangal in Tuburan. Other names given were Puh Gulangan (island of forest); Umus Tambun (fertile land); Kumalarang, named after a river; Baunuh Peggesan; and later it was changed to Basih Balan.
