Signal reconstruction for non-linearly distorted signal
Abstract: Aspects relate to reconstructing a received non-linearly distorted (e.g., clipped) signal. A transmitting device may non-linearly distort a signal to be transmitted (e.g., by clipping peaks of the signal). A receiving device uses a signal reconstruction procedure to reconstruct the original signal. For example, the receiving device may estimate the non-linear distortion (e.g., due to clipped peaks) in the received signal by slicing the received signal, and applying a non-linear distortion to (e.g., clipping) the sliced signal using a threshold that corresponds to a threshold (e.g., a clipping threshold) used by the transmitting device. The receiving device may thereby generate a reconstructed signal based on this estimate of the non-linear distortion.

Multiple input multiple output radio interference suppression and range extension
Abstract: A computer-implemented method, a computer program product, and a system include a processor(s) that produces a set of beamforming vectors, each vector produced based on a distinct set of parameters. To produce vector of the vectors, the processor(s) obtains, from receive antennas, data comprising a waveform comprising slots with boundaries, from a first collection window. The processor(s) determines the parameters (e.g., silent portion length and signal portion length) and determines which slots of the waveform contain signal operating instructions. The processor(s) aligns the slot boundaries, utilizing the data, based on determining which slots of the waveform contain signal operating instructions. The processor(s) extracts the signal portion and the silent portion, determines a covariance for each, and determines a vector and eigenvalue.

Sudanese Shi'ites hold rare public celebration
August 10, 2009 (KHARTOUM) — Several hundreds of Sudanese Shi'ites have held what is believed to be their first religious celebration in the predominantly Sunni country.
Shiite pilgrims beat themselves with ceremonial chains as they march toward the Imam Mousa al-Kazim shrine to commemorate the revered imam's eighth century death in northern Baghdad, Iraq on 17 July 2009 (AP)
The London based Al-Sharq Al-Awsat newspaper reported that the Shi'ites rallied in Jabal Awliya suburb 40 kilometers South of Khartoum to celebrate the birthday of Imam Al-Mahdi, a messiah-like figure for the sect.
The participants included university students, lecturers, politicians, journalists and students of religious seminars.
The exact figures of Shi'ites in Sudan is unknown but is believed to be expanding rapidly.
A religious official told the newspaper that the government in Khartoum was aware of the gathering and keeping a watchful eye out for any misbehavior.
"We won't allow any activity that diminishes the associates of the Prophet, peace be upon him" the official said, implying that the government would not tolerate attacks against the more prevalent Sunni belief.
A growing Shi'ite influence in Sudan could be the result of close relations between Sudan and Iran, the latter being the country with the largest Shi'ite population in the world.
Government sources told A-Sharq Al-Awsat that the government did not oppose Shi'ite activities in the country because "it's linked to the good relations with Iran and the government doesn't want any interference to damage these relations.".
In the past, Sunni Islamists in Sudan have accused Iran of trying to spread its brand of Shiite Islam in the East African country through a propaganda campaign.
Three years ago the Sudanese chapter of the Muslim Brotherhood said it had presented evidence of Teheran's attempts to convert locals to Shi'itism.
"It's a large scale plan conceived by Shiite groups and local organizations with the objective of spreading Shi'itism in Sudan," a spokesman for the group told the Arab daily al-Hayat.
Sunni groups have denounced what they say is a "Shiite peril" and the opening of several Shiite mosques in Khartoum.
They have asked authorities to close down the Iranian embassy's cultural centre and to prevent it from holding conferences which they say are being used for propaganda purposes.
"Shiite penetration in Sudan has become possible because of a lack of control on the part of the authorities," the Muslim Brotherhood's Sudan country representative, Sadiq Abdullah Abdel-Majid, said.
In 2006, an Iranian exhibit at the Khartoum International Book Fair was closed by authorities after it displayed books that allegedly contained blasphemous content against Sunni Islam.

Colzyx AB is a biotech company that emphasizes innovative research and development activities to utilize biological modes of action for use in advanced wound management. We envision taking advantage of naturally acting biomechanisms to obtain rapid wound closure, decrease bacterial wound infections and thus accelerate wound healing. The original discovery by the research team behind Colzyx was that Collagen VI, a molecule naturally occurring in all connective tissues, harbors such advanced wound healing properties. In preclinical studies (in vitro and in vivo), Collagen VI, or bioactive peptides derived from Collagen VI, have been confirmed to exert these complementary modes of action.

Q: Show that $X$ is a $T^1$ space. Let $X$ be a topological space. Let us construct the diagonal $D$ as $D=\{(x,x)|x ∈X\}$. Given that $D$ is the finite intersection of open sets in $X$x$X$. Prove that $X$ is a $T^1$ space.
I take  two distinct points $x$ and $y$ in $X$. We assert that there exists open sets $U$ of $x$ and $V$ of $y$ such that $U$ and $V$ are disjoint. Since $D$ is the finite intersection of open sets in $X$x$X$ then $D$ is open and consequently $D^c$ is closed, where $D^c$ implies complement of $D$ in $X$x$X$. Then the point $(x,y)$ belongs to $D^c$. But from here how can I find two disjoint open sets $U$ of $x$ and $V$ of $y$ to show that $X$ is a $T^1$ space.
Please help me to solve this.

A: $D$ being a finite intersection of open subsets is open itself. Pick any $x\in X$. By the definition of product topology there are $U,V\subseteq X$ open such that
$$(x,x)\in U\times V\subseteq D$$
It follows that $U=V=\{x\}$ because otherwise, if for example some $y\in V$, $y\neq x$ then $(x,y)\not\in D$.
In particular $\{x\}$ is open and thus $X$ is discrete.

A: If $D$ is the intersection of a (not necessarily finite) collection of open sets , so $D = \bigcap_{i \in I} O_i$ where all $O_i \subset X \times X$ open, then $X$ is $T_1$ (and the reverse also holds):
Let $x \neq y$ in $X$. Then $(x,y) \notin D$ so there is some $i_0 \in I$ such that $(x,y) \notin O_{i_0}$ and also some $i_1 \in I$ such that $(y,x) \notin O_{i_1}$. Also, from the definition of product topology and the fact that $(x,x) \in D \subseteq O_{i_1}$ we get that there is some open $W_x$ in $X$ such that $(x,x) \in W_x \times W_x \subseteq O_{i_1}$. But then $x \in W_x$ and $y \notin W_x$ (or else $(y,x) \in O_{i_1}$, which was not the case). Likewise, considering $(y,y)$ and $O_{i_0}$ we find an open set that contains $y$ but not $x$. Together we see that $X$ is $T_1$.

3 ways to keep your little rebel's attention during lockdown (without bribing them with sugar)
The pandemic came with a lot of rules and instructions on what to do and what not to do. But it seems like the "How to manage the hell raisers while they're home every second of the day" guide got lost in the mail. We've all had our zoom calls interrupted by a tantrum enough times now so we're here to lend a hand! Here are a few ways to make sure your little rebels never feel bored again
Build a routine together.
Usually, both you and your kid have a pretty set routine. But the P-word has thrown that into a loop. Still, it's essential to build a new routine together. That structure will not only keep them busy but also make things feel more like normal. Break down their day into different activities like craft time, playtime, watching time, and our personal favourite, nap time. Chores are another great way for you and them to spend some time together (and make them a lot more fun). An extra hand around the house always beats doing the dishes alone.
Start something new, together
Instead of trying to get them to do something you like or vice versa, find a middle ground that's new for both of you. It could be anything from building Lego sets to cooking to origami. The important thing is doing it together. Spending that quality time with each other will make your relationship with them that much stronger and actually help you learn who they are, and vice versa. After all, every Jedi needs a good Padawan!
Organise virtual playdates:
School was where we made our first friends and actually started interacting with people our age. But since that's not happening right now, keeping that social interaction alive is more important than ever. We're not saying it's time to throw caution to the wind and head out mask-less (please stay indoors and safe) but we can try to replicate the interaction virtually. Plan a movie-watching party with their buds or post-lunch book club to help them build their relationships and not hang out with their mom or dad. Works for both sides!
It's hard being a parent right now. And it's usually hard being a parent even when there isn't a global pandemic going on outside. But we know that you guys are absolutely killing it and growing alongside your kids too! Sure there'll be some missteps here and there but hey, that's what a second child is for (we kid). We'll make it through this in one piece and hopefully make some memories on the way as well.

Before getting to the today's Android App Updates, let's discuss about the upcoming Google Play update. Google is planning to separate tablet optimized apps from other apps in Google Play. In other words, when you open the Google Play application on your tablet, you are redirected to the section which only tablet-optimized application can be found (It is obvious that you can still install other application, which are only optimized for phones, on your tablet). As stated by Google, this service will be available from November 21. We believe this this distinction will lead to a win-win deal for both users and developers, since developers can focus on developing more tablet-optimized apps, while they are sure that users can find these apps easier than before.

Other than this Google Play update, Microsoft released a huge update for its favorite mail client, and Spotify as the leading app for streaming music, added some new features and fixed some bugs.
The most important change in the best Android App for Streaming Music, is the feature to filter sub-genres in Browse. Other than fixing some bugs and minor improvements, there have been some changes in the new releases section for a better experience.

Q: Jetpack compose width of row children In Jetpack Compose, How to find the width of each child of a Row?
I tried using onGloballyPositioned like below, but the size is wrong.
Also, not sure if this is the optimal one.
I need the width of each child and further processing will be done based on that, the below is a simplified code for example.
@Composable
fun MyTabSample() {
    MyCustomRow(
        items = listOf("Option 1 with long", "Option 2 with", "Option 3"),
    )
}

@Composable
fun MyCustomRow(
    modifier: Modifier = Modifier,
    items: List<String>,
) {
    val childrenWidths = remember {
        mutableStateListOf<Int>()
    }
    Box(
        modifier = modifier
            .background(Color.LightGray)
            .height(IntrinsicSize.Min),
    ) {
        // To add more box here
        Box(
            modifier = Modifier
                .widthIn(
                    min = 64.dp,
                )
                .fillMaxHeight()
                .width(childrenWidths.getOrNull(0)?.dp ?: 64.dp)
                .background(
                    color = DarkGray,
                ),
        )
        Row(
            horizontalArrangement = Arrangement.Center,
        ) {
            items.mapIndexed { index, text ->
                Text(
                    modifier = Modifier
                        .widthIn(min = 64.dp)
                        .padding(
                            vertical = 8.dp,
                            horizontal = 12.dp,
                        )
                        .onGloballyPositioned {
                            childrenWidths.add(index, it.size.width)
                        },
                    text = text,
                    color = Black,
                    textAlign = TextAlign.Center,
                )
            }
        }
    }
}

A: The size you get from Modifier.onSizeChanged or Modifier.onGloballyPositioned is in px with unit Int, not in dp. You should convert them to dp with
val density = LocalDensity.current
density.run{it.size.width.toDp()}

Full code
@Composable
fun MyCustomRow(
    modifier: Modifier = Modifier,
    items: List<String>,
) {
    val childrenWidths = remember {
        mutableStateListOf<Dp>()
    }
    Box(
        modifier = modifier
            .background(Color.LightGray)
            .height(IntrinsicSize.Min),
    ) {

        val density = LocalDensity.current
        // To add more box here
        Box(
            modifier = Modifier
                .widthIn(
                    min = 64.dp,
                )
                .fillMaxHeight()
                .width(childrenWidths.getOrNull(0) ?: 64.dp)
                .background(
                    color = DarkGray,
                ),
        )
        Row(
            horizontalArrangement = Arrangement.Center,
        ) {
            items.mapIndexed { index, text ->
                Text(
                    modifier = Modifier
                        .onGloballyPositioned {
                            childrenWidths.add(index, density.run { it.size.width.toDp() })
                        }
                        .widthIn(min = 64.dp)
                        .padding(
                            vertical = 8.dp,
                            horizontal = 12.dp,
                        ),
                    text = text,
                    color = Black,
                    textAlign = TextAlign.Center,
                )
            }
        }
    }
}

However this is not the optimal way to get size since it requires at least one more recomposition. Optimal way for getting size is using SubcomposeLayout as in this answer
How to get exact size without recomposition?
TabRow also uses SubcomposeLayout for getting indicator and divider widths
@Composable
fun TabRow(
    selectedTabIndex: Int,
    modifier: Modifier = Modifier,
    containerColor: Color = TabRowDefaults.containerColor,
    contentColor: Color = TabRowDefaults.contentColor,
    indicator: @Composable (tabPositions: List<TabPosition>) -> Unit = @Composable { tabPositions ->
        TabRowDefaults.Indicator(
            Modifier.tabIndicatorOffset(tabPositions[selectedTabIndex])
        )
    },
    divider: @Composable () -> Unit = @Composable {
        Divider()
    },
    tabs: @Composable () -> Unit
) {
    Surface(
        modifier = modifier.selectableGroup(),
        color = containerColor,
        contentColor = contentColor
    ) {
        SubcomposeLayout(Modifier.fillMaxWidth()) { constraints ->
            val tabRowWidth = constraints.maxWidth
            val tabMeasurables = subcompose(TabSlots.Tabs, tabs)
            val tabCount = tabMeasurables.size
            val tabWidth = (tabRowWidth / tabCount)
            val tabRowHeight = tabMeasurables.fold(initial = 0) { max, curr ->
                maxOf(curr.maxIntrinsicHeight(tabWidth), max)
            }

            val tabPlaceables = tabMeasurables.map {
                it.measure(
                    constraints.copy(
                        minWidth = tabWidth,
                        maxWidth = tabWidth,
                        minHeight = tabRowHeight
                    )
                )
            }

            val tabPositions = List(tabCount) { index ->
                TabPosition(tabWidth.toDp() * index, tabWidth.toDp())
            }

            layout(tabRowWidth, tabRowHeight) {
                tabPlaceables.forEachIndexed { index, placeable ->
                    placeable.placeRelative(index * tabWidth, 0)
                }

                subcompose(TabSlots.Divider, divider).forEach {
                    val placeable = it.measure(constraints.copy(minHeight = 0))
                    placeable.placeRelative(0, tabRowHeight - placeable.height)
                }

                subcompose(TabSlots.Indicator) {
                    indicator(tabPositions)
                }.forEach {
                    it.measure(Constraints.fixed(tabRowWidth, tabRowHeight)).placeRelative(0, 0)

Karen Dennis wins Fulbright award to teach in Russia
Rachel Hatch	April 6, 2019 Filed Under Academic Affairs and Provost College of Applied Science and Technology Fulbright International Studies Kinesiology and Recreation
Vladimir State University.
Karen Dennis
The U.S. Department of State and the J. William Fulbright Foreign Scholarship Board recently awarded Illinois State University's Karen Dennis a Fulbright U.S. Scholar Program award to teach at Vladimir State University in Vladimir, Russia.
An instructor in the School of Kinesiology and Recreation at Illinois State, Dennis will lecture at Vladimir State as part of a project to teach a new course in physiology and hygiene. She will also conduct workshops on design principles and theory for online teaching and learning. The author of The Effectiveness of an Online Fitness Course, her scholarly work has appeared in such journals as Medicine and Science in Sports and Exercise and Research Quarterly for Exercise and Sport.
"Dr. Dennis exemplifies Illinois State's core values through her scholarship and teaching. She continues to build international bridges that benefit students, faculty, and administrators at both universities," said University President Larry Dietz.
Dennis, who earned a doctorate in education from Illinois State, has presented at international conferences in Vladimir, and hosted Russian physicians in the United States.
The City of Vladimir is designated a "Sister City" with Bloomington-Normal, and has hosted students, faculty, staff, and community members in Russia. Later this month, Illinois State will host the rector (president) of Vladimir State on a visit to campus.
The Fulbright U.S. Scholar Program is administered at Illinois State University by Fulbright Program Advisor Lea Cline, Fulbright Scholar Liaison Erin Mikulec, and Interim Fulbright Program Advisor Joseph Zompetti.
Dennis is one of more than 800 U.S. citizens who will teach, conduct research, and/or provide expertise abroad for the 2019-2020 academic year through the Fulbright U.S. Scholar Program. Recipients of Fulbright awards are selected on the basis of academic and professional achievement as well as a record of service and demonstrated leadership in their respective fields.
The Fulbright Program is the flagship international educational exchange program sponsored by the U.S. government and is designed to build lasting connections between the people of the United States and the people of other countries. The Fulbright Program is funded through an annual appropriation made by the U.S. Congress to the U.S. Department of State. Participating governments and host institutions, corporations, and foundations around the world also provide direct and indirect support to the Program, which operates in over 160 countries worldwide.
Since its establishment in 1946 under legislation introduced by the late U.S. Senator J. William Fulbright of Arkansas, the Fulbright Program has given more than 380,000 students, scholars, teachers, artists, and scientists the opportunity to study, teach and conduct research, exchange ideas, and contribute to finding solutions to shared international concerns.
Fulbrighters address critical global issues in all disciplines, while building relationships, knowledge, and leadership in support of the long-term interests of the United States. Fulbright alumni have achieved distinction in many fields, including 59 who have been awarded the Nobel Prize, 82 who have received Pulitzer Prizes, and 37 who have served as a head of state or government.

Flaws:
1) Static and 1.3 second dropout at 3:26 of "Let It Grow"
3) 1 second dropout at 3:37 of "Let It Grow"
4) 1 second dropout at 2:49 of "Attics Of My Life"
This recording has the same genealogy as the 3/5/94 I recently posted.
In the summer of 1999, Dick Latvala cloned the March 4-6 1994 run for a guy who hosted a Grateful Dead-themed radio show; I obtained copies from the radio host.
Unlike 3/5/94, this show was tracked pretty accurately. I did make minor adjustments to some track markers, again boosted the levels by about 20% (actually, 18% for reasons noted below) and again fixed a duplicated section of the track marker between "Drums" and "Space".
The show had the same low levels problem as noted in 3/5/94. However, the boost was a problem, since the music itself peaked a few times during "Drums", "Space", and "The Last Time". Accordingly, it was difficult to do an across-the-board boost, because that would have driven the levels -- at least for those songs, at certain parts -- throught the roof. So, I acted in the greater good, so to speak, and decided to boost the levels for the benefit of the entire recording. So, there are a few "hot" sections in those songs.
Furthur, there was a BIG problem with the "Drums" --> "Space" track marker. On my originals, "Drums" was the last song of Disc 2, and "Space" was the first song of Disc 3. Come to find out that when those songs were tracked together, the volume levels didn't match; "Space" was quite clearly louder, even the waveforms looked markedly different. So, the splice was a problem since the levels didn't match. Again, quite similar to the 3/5 seam, the first 15 or so seconds of "Space" was duplicated at the last 15 or so seconds of "Drums". However, when I chopped off the duplicated sections, I still had a marked difference in volume. So, because I have entered this little project not wanting to fade anything in or out, the volume markedly increases at about 15:28 of "Space". "It is what it is", as they say these days.

Our West Coast accommodations, the Heartland Hotel Fox Glacier and Heartland Hotel Glacier Country offer visitors comfortable hotel accommodation close to the Fox Glacier and Westland World Heritage Park.
The impressive Fox Glacier is fed by four alpine glaciers and forces its path down the Cook river bed from the majestic Southern Alps. Visitors can not only view the glacier, but can walk up onto it, heli-hike or ice climb on it too. With early morning reflections of Aoraki/Mount Cook and Mount Tasman to admire in the still waters of Lake Matheson, there are countless more breathtaking scenes for visitors from the world over to experience in Westland World Heritage Park on New Zealand's West Coast.


Mining and Fracking Storage Tanks – Steel Core understands that methodologies utilized in mining and fracking need to be as low-impact upon the environment as possible. Water at mining site, be it stormwater run-off or wastewater generated from processing requires strict management to avoid adverse contact with the environment.
Mining wastewater used usually treated to remove dissolved metals and organic and inorganic pollutants. Initially this takes place in large "settling" tanks. For this purpose Steel Core manufactures Temporary Storage Tanks in capacities up to 2,000,000 gallons. Once the solids have settled the wastewater then goes through further treatment involving removal of residual chemicals and organic-inorganics associated with the particular types of mining that water is derived from. Steel Core offers a wide variety of holding tanks for these processes with "specialty" liners to handle the caustic substance present in this kind of wastewater.
Fracking involves mixture of water, sand, and chemicals under high pressure being injected into the ground to remove oil and gas from rock. Pockets of underground salt water are also occassional hit and create a high saline wastewater by-product of the fracking process.
Steel Core offers Temporary Storage Tanks with XR-5 and other "specialty" liners that can withstand these harsh chemicals. Complete with floating covers these tanks can handle capacities up to 2,000,000 gallons and can be easily disassembled and reassembled from site to site.

The fascinating compounds of plants
Researcher profile: Jake Stout
TOPICS:science
Photo credit: Jake Stout
By Jeremiah Yarmie March 2, 2016
Members of the plant kingdom make hundreds of thousands of molecules called secondary metabolites. These compounds aren't crucial for life, but are instead used for things like communication and defense – think of the poisons found in hemlock, which was used to kill Socrates, or capsaicin, which is found in chili peppers to deter herbivorous mammals.
Jake Stout, an assistant professor in the department of biological sciences, is interested in plant metabolites, especially those with medicinal potential.
"Collectively, you could say that plants are better chemists than us," Stout told the Manitoban.
These medicinal compounds are often produced within specialized plant cells through a conveyer belt of enzymes called a biosynthetic pathway. A gene in the plant's DNA encodes each of these enzymes.
Stout uses a genomic technique called transcriptome sequencing, which takes snapshots of the genes that are being used in plant tissue at particular moments in time.
Genes only work through intermediate messenger molecules. Transcriptome sequencing allows Stout to see what messages are being used where, and what those messages say.
From the information gathered using this technique, specific genes of interest can be singled out to answer questions like "what step along the pathway is this?" and "what goes in and comes out?"
"In doing that with a whole bunch of genes, we can reconstitute the entire biosynthetic pathway that a particular plant uses to make those compounds," said Stout.
By understanding these pathways, biochemists stand a better chance of synthesizing these compounds in the lab.
A main subject of research in the Stout lab is the African shrub Tabernanthe iboga, which produces the psychedelic drug ibogaine.
Ibogaine isn't commonly used recreationally – it has unpleasant effects and induces a rapid heartbeat – but it does show medical potential in the treatment of addictions.
"There is anecdotal evidence that ibogaine is able to partially reset the neurochemical pathways associated with addiction in the brains of people with dire opiate addictions," said Stout. "They say that they don't have withdrawal symptoms for weeks."
Stout is also interested in the evolutionary history that resulted in the formation of medicinal compounds.
Information about ibogaine synthesis would lend itself to understanding the synthesis of other compounds as well.
"Ibogaine belongs to this whole class of compounds called monoterpene indole alkaloids," said Stout. "They tend to be really complicated molecules, so we're not very good at making them."
Amongst this class of compounds are the chemotherapy drugs vinblastine and vincristine, which are isolated from the Madagascar periwinkle.
"In India and Madagascar, companies grow thousands of acres of these periwinkles to extract vinblastine and vincristine," said Stout. "The Madagascar periwinkle only makes these compounds in at around 0.01 per cent by weight, which is just a whiff."
In contrast to the periwinkle, iboga produces ibogaine in its roots at about four per cent by weight.
"The production of ibogaine is similar to the production of half of vinblastine," said Stout. "One of those halves is catharanthine, and I think that the biosynthesis of ibogaine goes through catharanthine."
If Stout were able to stop the biosynthetic pathway of ibogaine right after catharanthine, he would be able to produce the vinblastine precursor in iboga at yields much higher than the finished product in periwinkles.
"I'm coming up with devious ways to make the other half of vinblastine," said Stout.
Perfecting this would lower the price of the anti-cancer drug, increase its accessibility, and open up land for agricultural use.
Using this information, Stout hopes to sample other plants in the iboga family for genes involved in the production of different monoterpene indole alkaloids.
"We could potentially produce a whole bunch of these molecules in the iboga system," said Stout.
For his PhD, Stout studied the production of lignin, a polymer responsible for the rigidity of plants like trees.
"In looking at the way that biosynthesis works, I started looking at structurally related compounds," said Stout. "Mescaline has almost the exact same structural pattern as some of the lignin monomers."
Mescaline is a psychedelic drug found in the peyote cactus – it's what Owen Wilson's character was high on in The Royal Tenenbaums.
"I think that mescaline biosynthesis might be the entire lignin biosynthetic pathway just moved over a step," said Stout. "From an evolutionary standpoint, it would be like an entire pathway being co-opted, rather than just bits and pieces."
"Plant-produced psychedelic compounds are really interesting because they've been used for thousands of years by different cultures for medicinal and ritualistic purposes. Knowing how these compounds are produced adds to that indigenous knowledge, and will allow us to produce other medicinal compounds such as vinblastine at reduced cost," Stout told the Manitoban when asked about what it's like working with drugs commonly known for their hallucinogenic effects.
"Besides, it's kind of awesome to work on plants that are illegal in a lot of the world because it cuts down on competition."

I am always multitasking : I do my grocery shopping between 2 extracurricular activities, do the laundry while helping my son with his homework. But when it comes to birthday gifts, I take my time and choose a gift with care. It is so important to show the child that you cared about his or her birthday.
But since I am always lacking time , I don't like running from a store to another to find a gift and taking the risk not to find the proper gift. I play it safe and go to my favorite kids store: Indigo Kids. I am sure I will find smart gift recommendations for every age (1-9) selected by their expert buyers. It is the first kids retailer in North America to earn the Parent Testes Parent Approved seal of approval. You can even shop online at Indigo Kids in the comfort of your home. Even if I like shopping online while sipping my favorite tea, I usually go to the Indigo Store. It's only 10 minutes drive and I love their store design. I sometimes find some cute items for the home.
I headed to the store on this Monday evening to buy a gift for my niece who was celebrating her 4-year-old birthday. I went shopping with my 10-year-old who was on spring break. He will help me choose the proper gift for her. My son and I could not get out of the store!! We had so much fun.
We picked their Blue large shopping bag and went to the Kid's section. We noticed that a group of kids were playing and doing crafts with the store's staff. A sweet lady who served us a free hot chocolate said it was part of the spring break activities. Each day, the store organizes crafts, story tims, magciansa for free. Head over to their Events page for more details. The aisles are large enough for strollers!
The store is organized in sections by ages which makes it easier to choose. We went to the 3 to 5-year-old section. On the right we had books, all kinds of books. Some of them were on sale. On the left were the toys: dolls, scrapbooks, cooking sets, etc. Each class was nicely organized and easy to look at. I concentrated on the educational toys that helped develop her fine motor skills and be ready her for school.. I chose 2 items for my 4-year-old niece: one to practice her alphabet and another to make craft. My son suggested the craft one as it included scissors, glue. He said: she will go to school only in 2 years. She will have time to practice her alphabet. But let her have fun with these crafts. It will help her with her fine motor skills. He was right: we took the Crafty set.
We paid for the gift (Which costs $35) and earned my plum rewards (their fidelity program). You can earn points with every purchase. Then we enjoyed the free gift wrap!
The gift was a big hit with my niece. She loved it and immediately started playing with it! Thanks to INDIGO and with the help of my son, I put a huge smile on my niece's face. Now you can live this great experience by winning a $35 Indigo Gift card. You can shop online or in the store!

I know I am always going on and on about raising your plants from seed and as long as I can draw breath I will continue to do so because there is nothing more exciting than seeing the seedlings flower for the first time. This is a lovely selection raised from our own garden seed of the wonderful 'Penza Group' of Corydalis solida that Janis Ruksans introduced. We get more variation of colours from white through to red from this group than from any of the other C. solida introductions we grow.
This is the first seedling in a potful of young bulbs raised from an open pollinated plant of Ipheion 'Froyle Mill' and it is quite distinctive - I wonder what the sibling plants will look like.
Although they are not the most showy of flowers I find the Muscari fascinating but you have to get up close to appreciate their charm. If you look at them even from standing up they just appear as blue spikes but get down close where you can start to see the details of each individual flower and another level of beauty is revealed. The one problem I have is I have terrible trouble naming them - well if I tell the truth I have not studied the taxonomy that closely so I tend to stick with the names I got them as such as the pale blue M. libanoticum and the seed raised Muscari sp collected in Turkey.
One of the most beautiful ones I grow is this miniature beauty again just Muscari species from Turkey for the moment - I was given a few years ago by a good friend so I tend to call it Arthur's Muscari to remind me of his generous gift. It is amazing how names like this can stick - when Fred Carrie was running his nursery he would sometimes come and get some cutting material from our garden and one time he liked a small compact Hebe which had self seeded in one of our beds, perhaps a hybrid between some of the many species we were growing. Fred just wrote Hebe - Ian Young on the bag with the cuttings and took it back to the nursery where his propagator assistants went to work and produced a batch of plants. The next thing I knew a few years later was my sister phoned to say she had just bought a Hebe 'Ian Young' in a garden centre; was this anything to do with me!! Obviously Fred's assistant had taken the label on the bag as the name of the plant and had labelled up all the plants for wholesale.
Despite the dreadful weather conditions where one day it is mild with bright sunshine and the next freezing conditions with driving snow storms most of the bulbs are making the best of it. On the left is a white Fritillaria persica distinguishable even by the paler leaves and a good form of F. imperialis 'Maxima' on the right with lovely bronze edged leaves. I hope the weather improves before they start to open their flowers so I can enjoy them.
In the frit house there is an element of protection from the worst of the weather but the temperature swings are not the best conditions for pollen to grow and fertilise the ovules so I suspect it will be another poor year for fritillaria seed.
Flowering for the first time from J&JA seed is the lovely long hanging flower of Fritillaria forbesi. This is a rare Fritillaria in cultivation and the true plant is hardly ever seen but the name does appear; more often mistakenly applied to other plants, most commonly it is F bithynica that is the impostor. I am attending this flower daily with my paint brush transferring pollen from anther to stigma - I would love to get seed from it.
Talking about impostors here is another form of Fritillaria montana that I discussed the other week - this is a fine form with three flowers per stem.
There has been some discussion in the forum recently of impostors appearing in place of Fritillaria michailovskyi. This is one of my own pots of seedlings taken from a fine form of Fritillaria michailovskyi and it has obviously hybridised with another frit in our glasshouse - I speculate that F. crassifolia is the other parent. It is an interesting plant with some charm but if you were expecting the very clearly marked and beautiful Fritillaria michailovskyi then you would be justified in feeling disappointed.
Here is the true and typical Fritillaria michailovskyi raised from seed collected many years ago in Turkey showing the very clear and dramatic break between the two contrasting colours.
Of course Fritillaria michailovskyi is not the only one to have this colour combination Fritillaria reuteri also has the same colouring but is easily distinguished by having more open flowers among other features.
Looking up into the flowers of frits is important because it lets you see the form of the style and the shape of the nectaries at the base of the petals - these are important diagnostic characters used to identify species.
I have always known these as some of the many forms of Fritillaria hermonis amana we grow but recently the Wallis' have separated F. hermonis from F. amana and one of the reasons they give in their paper is the shape of the nectary. To comply with this new order this plant on the left would now be known as Fritillaria hermonis and Fritillaria amana is on the right. I have read the Wallis paper and I can see the clear distinction between the typical Fritillaria hermonis and the typical F. amana as they describe them but like many other species it is the forms that start to merge in the middle, the atypical forms that cause me the problems; what do I call them?
A beautiful Chinese species is Fritillaria yuminensis; it also has a nice scent. I first imported some bulbs about ten years ago and since then I have been raising it from seed when the weather allows for a successful fertilisation.
To ensure the plant has the best chance to set seed I transfer pollen from the stamens to the style every day for as long as the flower remains viable. To ensure that I can continue to grow and enjoy these beautiful bulbs in the long term it is vital that I raise them from seed on a regular basis and that I do not just rely on the vegetative, clonal, methods of propagation. The myth that allowing a bulb to set seed weakens the bulb is in my mind not true. I have conducted trials and found that the bulb that has been fertilised and allowed to set seed grows for four to six weeks longer than the same bulb that is not setting seed. That extra growing time is more than enough time for the plant to take up the extra energy required to produce the seed and grow the bulb to a good size.

An initiative to divert waste glass from landfill to seacoast by educating, adding disposal sites, and custom processing collected glass into graded glass-sand for use by the coastal restoration industry.
GlassLand Project founder and director Guy Seaberg, is the founding partner and CEO of TrialVue, LLC, a litigation support company providing courtroom technology services to trial lawyers. A graduate of Georgetown (BA) and Northwestern Law (JD), he has taught trial practice in the USM paralegal certification program and instructed in criminal and civil procedure as Director of the USM Legal Aid Clinic — in addition to training paralegals as digital trial assistants. He conceived and built Stage One experimental theatre at Georgetown University and was founder and Director of Seaberg/Isthmus Gallery and Framing in Chicago and FLUX Contemporary Gallery in Albuquerque, NM. One tough winter in LL Bean's home-base of Freeport, Maine, he conceived and built the life-saving Rosendo snow-mover device, later conceived and developed in Santa Fe, NM the ArtVuer studio App, and once proudly served as personal assistant to Mr. Louis Armstrong and his Orchestra during their memorable concert series at DAR Hall in Washington, DC. With a wide array of interests and the demonstrated ability to identify and develop better systems, services and products in a range of fields, Seaberg has what it takes to shepherd an undertaking as ambitious as The GlassLand Project to fruition.
Partner Tom Seaberg is an electrical engineer from Southern Illinois University, specializing in the design and construction of computerized control systems for manufacturing assembly lines. His clients have included Mercedes-Benz in Montgomery, AL and Ford Motors in Detroit, as well as scores of meat-processing companies throughout the US and abroad. An innovator responsible for several patented improvements and modifications to control and manufacturing components, Tom is less the entrepreneur than the go-to guy for making something work at the outset, or continue working after malfunction. A veritable White Knight, he's the guy GlassLand needs to design and supervise its glass waste manufacturing and packaging facility – a CTO to depend on for turning mountains of waste glass into suitable sand replacement.
Another lawyer by training — specializing in corporate business law — Partner Christopher Prasad now owns and operates Phoenix Recycling, a New Orleans regional company known for its reliability and guaranteed 360 degree recycling of the reclaimable materials it collects. Exchanging suit and wingtips for t-shirt and sneakers, Chris identified the growth potential of the recycling industry early on, started with one truck and a handful of apartment complex owners willing to pay for honest recycling, and eventually bought Phoenix – in dire financial straits but with a brand, a vehicle fleet and a bank of customers. With Chris at the helm, Phoenix has grown to profitability in service of a large NOLA base of commercial customers including most of the large hotels, restaurants and bars in the French Quarter, Dryades Market and dozens of others; his timing in securing these accounts was right on the mark – as waste producers shifted from reluctance to pay for collection to full acceptance of the cost. Faced now with an opportunity to expand commercial glass collection far beyond Phoenix's current capacity, the challenge of where to process the collected glass, and the evolution of a single local coastal restoration industry to buy reprocessed cullet, Chris is an essential partner in the Glassland Project, anxious to expand collection, build the plant and manufacture custom glass-sand product for coastal restoration. With the experience of day-to-day management of a successful collection company, a prior, last-round-level proposal and pitch for a "Public Space Recycling" venture at The Idea Village, and legal savvy, Chris's business and growth management skills, industry awareness and existing network serve the project ideally in his service as COO.
Partner Joseph Santiago, Glassland's Communications Director, has 12 years of experience as a teacher and facilitator in a range of industries, including staffing and professional service, manufacturing software, and education management. He's an expert in designing community learning networks (CLNs) and in utilization of blended environments to establish informational and cultural contact zones. As a digital literacy advocate, Joe's focus has been on developing programs for those who have traditionally struggled to be heard; accordingly, he has developed materials for documentaries, educational programs and workshops, as well as for social change endeavors like the World Voice Project. With a Masters in Psychology, and ABD status for a PhD in Industrial and Industrial Organizational Psychology, he was the founder and president of Santiago, Inc., established one of the world's largest global CLNs, was an instructor at the Center for Student Leadership Development at the University of Rhode Island, and is currently the (remote) Director of IT and Communications for the Rhode Island Advocacy for Children Program. An expert in human behavior and motivation, in his "spare time," Joe has written and published five books of fiction, and he's one of the select group of outdoorsmen and women to have been honored with the estimable Triple Crown Award from the American Long Distance Hiking Association–West in recognition for completing the Continental Divide Trail (3,100 miles), the Pacific Crest Trail ( 2,650 miles) and the Appalachian Trail (2,160 miles); with relentless focus and stamina, CIO Santiago puts one foot in front of the other … and gets the job done.
