"I will not die an unlived life.
I will not live in fear of falling or catching fire.
I choose to inhabit my days, to allow my living to open me, to make me less afraid, more accessible, to loosen my heart until it becomes a wing, a torch, a promise.
I choose to risk my significance; to live so that which comes to me as seed goes to the next as blossom and that which comes to me as blossom, goes on as fruit."

Weather Report - June 18, 2012
Heating Up This Week
A weak disturbance moving toward the coast of SW Louisiana will help to keep a few showers and t-storms in our forecast through the day. We've got rain chances posted at 30%, with highs topping out in the upper 80°s to near 90°. High pressure will gradually strengthen overhead as the week progresses, leading to hotter and drier conditions. Rain chances will be 20% or less each day from Tuesday into the weekend, with highs climbing into the low to mid 90°s. - Steve Caparotta / WAFB Storm Team
Weather Report - June 19, 2012
Drier, Hotter Next Few Days
Drier weather settles in over the next few days as a ridge of high pressure builds overhead. As you are most likely aware, less rainfall means more heat. Highs will range from the lower 90°s Tuesday through Thursday to potentially the mid 90°s by the weekend. While little rainfall is expected through Thursday, we will have to keep an eye on a tropical wave moving into the Gulf late this week. Most indications are that the bulk of this system will stay to our south, but it may get close enough to provide slightly better rain chances from Friday into the weekend. - Steve Caparotta / WAFB Storm Team
Weather Report - June 21, 2012
Yep...It Feels Like Summer
We’ll call it “warm” today as highs will actually stay right in line with the average high. We hit 91° today with highs in the mid 90°s by the weekend. The hotter weather doesn’t look to have any relief in sight as we stay mainly dry for the next 7 days. A spot or two of rain will be possible on Titan 9 Doppler each afternoon, but most if not all of us will stay dry. Morning starts will also start to climb in the mid 70°s by the end of the weekend. A tropical wave is pushing into the Central Gulf of Mexico. We will keep an eye on this unorganized system, but all indications are that it will not cause any problems for us locally. -- Jeff Morrow / WAFB Storm Team
Weather Report - July 9, 2012
Dry in June, Soggy in July!
Areas of moderate/heavy rainfall were reported throughout our viewing area this past weekend and it appears more wet weather can be expected over the course of the next several days! The ridge of high pressure - that had basically controlled our weather the past few weeks - is now shifting westward, allowing the influence of a trough as well as weak cool front (stalling to the north) keeps high rain chances in our forecast. At least a trade off ... "cooler" afternoon highs, in the upper 80s to lower 90s! - Diane Deaton, WAFB Storm Team

Westher Report - June 22, 2012
Staying Hot and Muggy
It’s getting hot outside these days. Highs are climbing towards the mid 90°s and will reach there by the weekend. It’s a mainly dry forecast but we may see a few spotty shower Saturday and again on Tuesday. This low chance for rain will do nothing to cool us down. Expect highs in the mid 90°s for the next 7 days. Conditions will also be very muggy with feel like temperatures in the triple digits during the mid afternoon. We are still watching a broad area of low pressure in the Southern Gulf of Mexico. We have a lot of uncertainty on how strong and where exactly this system will get. We’ll of course keep an eye on things for you. - Jeff Morrow / WAFB Storm Team

Debby Moves Away, Heat Moving In
It appears as though Debby has made up her mind and is not longer a direct threat to Louisiana. Debby is now forecasted to stay nearly stationary for a few days before moving north into Florida later this week. For us that means the forecast turns really hot with muggy conditions. Highs the next few days will be in the upper 90°s. Feel like temperatures will be well into the triple digits for most of the afternoon hours. Very little rain is expected over the upcoming week with only a few spotty to iso’d t-showers. - Jeff Morrow/ WAFB Storm Team
Weather Report - July 26, 2012
Heat Stays in our Forecast!
As Tropical Storm Debby continues to move VERY slowly to the east (landfall in northern Florida) extreme "heat" will be our weather story throughout the upcoming week! In fact, yesterday's high of 101 degrees at metro airport was not only a record for the date, it was our hottest day since Aug. 18, 2011! Unfortunately, with that ridge of high pressure overhead, hot and mainly dry weather will continue ... today's forecast high is 99 degrees, the record for today is 100 degrees set back in 1930! And, it appears the heat will stay with us over the course of the next several days - with only a "slight" rain chance the latter part of the weekend, into early next week! - Diane Deaton, WAFB Storm Team
Weather Report - June 27, 2012
Ozone Action Day
Now not only must we worry about the heat, but air quality has become a concern. An Ozone Action Day has been declared as ozone levels will be high for those with sensitive breathing issues. Another record high will be in jeopardy today. Highs will climb towards the triple digits Wednesday, but may stay in the mid 90°s for the rest of the week. We'll stay mainly dry during the next several days. We finally will introduce an iso'd shower to the forecast beginning Sunday and continuing into the work week. - Jeff Morrow & Diane Deaton, WAFB Storm Team
Weather Report - July 6, 2012
A Rainy Start to July!
At last, we have rain in the forecast ... not only for today but for the next several days! This returning wet weather pattern is due to a disturbance moving westward along the Gulf Coast; so, count on a 60% - 70% chance for showers/storms later today, 50-50 tomorrow, 30% Sunday. And, with the potential clouds and rainfall ahead, we'll also have slightly "cooler" daytime highs ... instead of the mid/upper 90s, "only" the lower 90s by early next week! - Diane Deaton, WAFB Storm Team

The Holy Grail Of High Performance
Now a network of research groups at the University of Huddersfield, linking scientists in a wide variety of disciplines, is taking diagnostic engineering and maintenance to new levels,
The Centre for Efficiency and Performance Engineering is headed by Professor Andrew Ball
“If you are a production engineer you want to make your assets last as long as possible,” he explains. “But you don’t want to run the risk of unnecessary failure. You need to estimate remaining useful life within a given risk. It is the holy grail of reliability and maintenance – what is the remaining useful life of the asset?”
Initially, Professor Ball established a Centre for Diagnostic Engineering at the University of Huddersfield.
But when its remit and range of expertise broadened, it was decided to create the Centre for Efficiency and Performance Engineering as the umbrella for four research groups covering fields that include condition monitoring, automotive engineering, emissions, biofuels, fault diagnosis and prognosis, measurement systems, aerodynamics and marine engineering.
The Centre lists at least 50 research areas between its four groups, which between them have a membership of some 35 academic and research staff, backed by a lengthy roster of research students.
There is a strong international dimension too, as the reputation of the University of Huddersfield in the field continues to attract high calibre researchers.
New arrival brings the Grail closer
Dr Van Tung
A recent arrival is Vietnamese-born Dr Van Tung Tran (pictured), a research fellow attached to both the Measurement Systems and Data Analysis and the Condition Monitoring and Diagnostics Research Groups.
Dr Tran comes to Huddersfield from Pukyong National University in South Korea, where he obtained his postgraduate qualifications and carried out cutting-edge research in fault detection and diagnosis that brings Professor Ball’s “holy grail” ever closer.
For example, Van Tung Tran has worked on the use of artificial intelligence and data-driven techniques to diagnose and prognose failures in machines.
He has also carried out important research in the use of thermal image analysis to provide near-instant information about incipient problems in a machine.
Professor Ball appraises some of Dr Tran’s recent work: “He takes conventional maintenance approaches like thermal imaging and he applies artificial intelligence to automate them, to make them more sensitive and to permit not only detecting of faults but how severe they are.”
He can then offer a prognosis, which means a production engineer can gain invaluable knowledge of how much useful life is left in a machine.
Professor Ball, who is also the University’s Pro-Vice Chancellor for Research and Enterprise, stresses that the work of all the scientists who work under the aegis of the Centre for Efficiency and Performance Engineering is geared to real-world demand and practical problems.
“Everything is user-led,” he says. “We don’t do blue sky thinking!”

How Atomic Scale Devices Are Transforming Electronics
A memristor, the first fundamentally new electronic circuit device in more than 100 years. Although memory resistance is fundamental to all matter, such devices are not practical except when fabricated on the nanoscale.
Joining the dialogue:
* Michelle Simmons, Scientia Professor and Director of the Australian Centre of Excellence for Quantum Computation and Communication Technology, University of New South Wales: "Other groups had found that making nanowires thinner than 10nm wide tended to deactivate their dopants, the atoms added to the wire to make it conductive. We embedded our wire in crystalline silicon to isolate the dopant atoms from surfaces and interfaces that caused this deactivation. We predicted this would give us highly conductive wires, and this is what happened.
The key to making these wires was combining scanning tunneling microscopy, a technique to image and manipulate individual atoms, with molecular beam epitaxy, a way of growing perfect crystals. It gave us great precision in all three dimensions, and when combined with a high density of the dopant atoms, allowed us to create these highly conductive nanowires."
* Paul Weiss, Fred Kavli Chair in Nanosystems Sciences at UCLA and Director of the California NanoSystems Institute: "Because we increasingly have tools to create and to examine precise structures, I think we're going to see more and more demonstrations of what happens at the atomic scale.
We're developing our ability to make nanostructures the same way every time, then manipulate these structures so we can look at very small variations. This allows us to understand their behavior much better, and then come up with clever ways to recreate them. We're never going to make a billion transistors by manipulating individual atoms, but maybe we can use our knowledge to develop chemistries that recreate those structures."
* Stan Williams, Hewlett-Packard Senior Fellow and director of the company's Cognitive Systems Laboratory: "From a commercialization standpoint, the most important thing about nanowires and single-dopant transistors is that they demonstrate scaling. Nobody is going to invest hundreds of millions of dollars in a new foundry if they're not sure it's going to work. Michelle's work shows that there's a “there” there. It is a very important demonstration."
Among the topics was the recent announcement by Simmons’ lab that it had created 4-atom-wide nanowires, as well as showed a working transistor made from a single atom. Significant achievements, Simmons believes that research in her field has advanced so far that it warrants special attention. “In every field, there is a time to accelerate your commitment," she said. "In quantum computing, that time is now.”
The researchers also focused on the difficulty introducing transformational advances to industry. Discussing Hewlett-Packard’s plan to commercialize a mass-market flash memory device based on memristors -- a new type of electronic device that stores information by manipulating the location of a few atoms -- Williams noted, “Development costs at least 10 times as much as research, and commercialization costs 10 times as much as development. So in the end, research -- which we think is the most important part -- is only 1 percent of the effort."

As director of the California NanoSystems Institute at the University of California, Los Angeles, Kavli Professor Paul Weiss heads an institute focused on advancing and speeding the commercialization of nanotechnology. Weiss said there are ways to improve the dynamics for progress. “At the same time that we're discovering new materials and new phenomena, we should be looking at how to integrate them into broader structures, to build robust systems, and to manufacture everything reliably. We can't ignore any one area. The beautiful part is when they start to come together.”

A New Class Of Unconventional Superconductors
Researchers at the Rutherford Appleton Laboratory and at the universities of Kent, Bristol and Huddersfield, in England, have discovered a new class of very exotic unconventional superconductors
Professor Bob Cywinski.
Superconductivity is one of the most fascinating phenomena known to humankind. When a superconductor is cooled below its ‘critical temperature’, the fluid of electrons, which is responsible for the conduction of electricity through the material, undergoes a radical re-organisation. The electrons form ‘Cooper pairs’ and these Cooper pairs condense into a single, collective quantum state, which means they all behave as a single entity. This allows the manifestation of quantum-mechanical effects, which are normally confined to the world of sub-microscopic particles, on a scale that is visible to the naked eye.
Much recent research on superconductivity has focused on the internal structure of these Cooper pairs. While in conventional superconductors (and also in some high-temperature superconductors) the electrons in a Cooper pair have their intrinsic ‘spins’ pointing in opposite directions, so that the total spin of the Cooper pair is zero, in other, more exotic ‘triplet’ superconductors the electronic spins line up, so the Cooper pair has some intrinsic spin of its own. Such is the case, for example, of the strontium ruthernate Sr2RuO4, which is the paradigmatic example of a triplet superconductor. However, whereas in Strontium Ruthenate the Cooper pair spins are randomly-oriented, so that there is no net spin of the condensate of Cooper pairs in this material, in other, even more exotic ‘non-unitary’ triplet superconductors the spins of the Cooper pairs point in a particular direction. This comes about because the electrons whose spins point in that direction are more likely to form a pair than other electrons.

Until very recently, however, all known non-unitary triplet superconductors where so for a fairly simple reason, the materials were ferromagnetic, meaning that they were naturally magnetised and therefore even before the onset of superconductivity the spins of their electrons, which act as tiny bar magnets, were already aligned in a given direction. This changed in 2009 when three of the present authors reported measurements and theoretical analysis suggesting that the superconductor LaNiC2 was a non-unitary triplet superconductor [A. D. Hillier, J. Quintanilla and R. Cywinski, Phys. Rev. Lett. 102, 117007 (2009)].
This was surprising because LaNiC2 is not ferromagnetic, meaning that there had to be some as yet unknown mechanism whereby the electrons that paired up in Cooper pairs did so with their spins aligned in a particular direction. How did they chose this direction? Did the unusual crystal structure of this material, which unlike most crystal lattices is not symmetric under inversion, have something to do with it?
The MuSR spectrometer at the ISIS Facility, STFC Rutherford Appleton Laboratory.
Now the present team has produced evidence of another material having this exotic property, namely LaNiGa2 [A. D. Hillier, J. Quintanilla, B. Mazidian, J. F. Annett and R. Cywinski, Phys. Rev. Lett.]. Like in the previous case, the measurements were carried out using the muon spin rotation technique at the ISIS Facility, Rutherford Appleton Laboratory. In this technique, a powerful particle accelerator is used to bombard a sheet of graphite with a proton beam, producing muons, a subatomic particle that is then implanted in the material to be studied. After a few microseconds, the muon disintegrates, emitting a positron that is detected by the experimental apparatus. The direction of emission of the positron contains information about the atomic-scale distribution of magnetization inside the material.
Unlike its cousin LaNiC2, the crystal structure of the new superconductor does have symmetry under inversion, but the chemical similarity of the two compounds suggests that they are two instances of a new family of superconductors that have non-unitary triplet pairing even though they are not ferromagnetic. In this latest publication, the team puts forward a possible explanation, they show, by a very general reasoning based on the fundamental symmetries of nature, that the natural tendencies in these materials to magnetise under the influence of an externally-applied magnetic field, what is called ‘paramagnetism’, can lead to the development of a magnetisation in response to the magnetic moments of the Cooper pairs themselves.
In other words, rather than relying on some pre-existing magnetisation, the magnetic moments of the Cooper pairs themselves create the magnetism that is required for their magnetisation to be energetically favourable – thus non-unitary triplet pairing can lift itself by its bootstraps. This would be a superconducting analogue of the way magnetism develops in ferromagnetic metals. A confirmation of this scenario would be quite spectacular, as it is a new form of magnetism that is generated by superconductivity.
The discovery of a new family of unconventional superconductors is a rare event. The challenge now is to reach a microscopic understanding of how this highly-exotic pairing structure comes about. There will also be a race to find more examples of this family as well as more experimental evidence, obtained with other techniques, of this unusual phenomenon.

Mystery Disease Killing Children In Cambodia, 56 Death In 74 Cases
Preliminary findings of the investigation identified a total of 74 cases who were hospitalised from April to 5 July 2012. Of these, 57 cases (including 56 deaths), presented a common syndrome of fever, respiratory and neurological signs, which is now the focus of the investigation.
The majority of the identified cases to date were under three years old. Most of them were from the southern and central parts of the country and received treatment at Kantha Bopha Children’s hospital, which is a reference paediatric hospital. Despite all efforts, many of the children died within 24 hours of admission.
Available samples have been tested at the Institut Pasteur in Cambodia. Although a causative agent remains to be formally identified, all these samples were found negative for H5N1 and other influenza viruses, SARS, and Nipah.
The Ministry of Health was first alerted to this by Kantha Bopha Children’s hospital in Phnom Penh, where the majority of the cases were hospitalised.
The Ministry of Health notified WHO about this event through the IHR notification mechanism as it met the criteria for notification of any event where the underlying agent or disease or mode of transmission is not formally identified.
WHO and partners are assisting the Ministry of Health with this event which focuses on hospitalised cases, early warning surveillance data, laboratory data and field investigations.
While this event is being actively investigated, the Government is also looking at other diseases occurring in the country, including dengue, hand-foot-mouth and Chikungunya.
Parents have been advised to take their children to hospital if they identify any signs of unusual illness. The Government is also reinforcing awareness of good hygiene practices to the public, which includes frequent washing of hands.

Repopulating Europe After The Ice Age
The Ice Age, however, eventually came to an end and as the ice retreated, Europe once again began to be populated by human beings. New research drawing in expertise from the Czech Republic, Estonia, Italy, Russia and the United Kingdom is giving us rare insight into how Europe became repopulated as the Ice Age ended. The findings were published in the American Journal of Human Genetics.
'The end of the Last Glacial Maximum allowed people to recolonise the parts of Europe that had been deserted and this expansion allowed increase of human populations,' said lead author Sardinian-born Dr Maria Pala, who began research into the topic while at the University of Pavia in Italy before moving to the United Kingdom.
Led by Dr Pala, who is currently based at the University of Huddersfield, United Kingdom, and her team showed how the Near East was a major source of replenishment when huge areas of European territory became habitable again, up to 19 000 years ago.
The Last Glacial Maximum, or Ice Age as it is more commonly referred as, lasted for around 7 000 years. When it began some 26 000 years ago, it was thought that there were two principal safe havens for humans. They were thought to exist in a "Franco-Cantabrian" area which roughly coincides with northern Spain/southern France, and a 'Periglacial province' on the plains in the Ukraine.
By analysing large quantities of mitochondrial deoxyribonucleic acid (DNA) from Europeans who belong to two major lineages - who share a common genetic ancestor - named J and T, the researchers filled in many of the gaps that have existed and created a more complete picture of early Europeans. What is known is that these haplogroups (groups sharing similar DNA traits such as J and T) originated in the Middle East, and up until now it was thought that they migrated to Europe in the Neolithic age, approximately 9 000 years ago.
However, the team provided evidence that shows humans belonging to the J and T haplogroups actually migrated to Europe much earlier than was previously thought, beginning as soon as the Ice Age started to end.
Aside from the purely scientific challenges and discoveries, Dr Pala believes that archaeo-genetics has important lessons to teach humanity: 'It (archaeo-genetics) helps us to reevaluate the perception of our identity. We are highly focused on identifying ourselves as Italians, British or whatever, but by analysing DNA we discover that originally, not such a long time ago, we came from a common source.'

Will Feel Like 100's Today
** Ozone Action Day Again Today **
The weather will remain hot and humid through the rest of the week. Obviously the best way to beat the heat is to stay indoors with the A/C, but if you have to be outside be sure to stay hydrated. Highs will stay in the mid to upper 90°s through the weekend. By the end of the weekend we may see an iso'd t-shower. A few sct'd showers and storms will be possible by the middle of next week allowing for highs to decrease a couple more degrees. Morning starts over the next 7 days will bounce around the low to mid 70°s. - Jeff Morrow & Diane Deaton / WAFB Storm Team
Weather Report - June 29, 2012
Hot Days - Summer in the City!
Again this morning, we're starting out in the mid/upper 70s ... ending up with an afternoon high in the upper 90s ("heat index" 100 - 105 degrees!). A ridge of high pressure continues to be the culprit - and that means a large part of the country is also sweltering under the ongoing oppressive summer heat! A stray shower can't be totally ruled out during the afternoon hours, but most of us will stay dry through the weekend. By early next week, we'll put a 20% - 30% chance for rain in the forecast; hopefully, a few neighborhoods will finally see some very welcome rainfall! - Diane Deaton, WAFB Storm Team
Weather Report - July 2, 2012
DEQ Declares "Ozone Action Day"
Today, our air quality forecast is "Code Orange", unhealthy for sensitive groups. As a result, our air quality could become a concern as winds stay light and, unfortunately, rain chances will still be quite limited. And, while we won't "technically" experience afternoon highs in triple digits, it certainly will "feel like" it ... as our heat index soars to over 100 degrees! Looking ahead, not much of any major change tomorrow and our 4th of July forecast should stay relatively dry (20%) with the main weather story being the heat!! - Diane Deaton, WAFB Storm Team
Weather Report - July 3, 2012
More Heat, Humidity - Little Rainfall!
Looks like the ongoing heat/humidity will stay with us through the week ... with highs rather consistent, in the mid 90s! Add to that just a little rainfall over the next few days and no relief by way of Mother Nature - until possibly over the weekend! Our forecast is now calling for an increase in rain chances by the weekend (30% - 40%) providing at least some momentary relief from the summer heat! As a result, scattered showers/storms should help to hold highs in the low/mid 90°s instead of the mid to upper 90°s! - Diane Deaton, WAFB Storm Team
Weather Report - July 5, 2012
Rain Chances on the Rise
Increased rain chances over the next several days should keep the summer heat in check. Highs will stay in the low to mid 90°s, but heat index values should stay much lower. Not to mention as showers and storms begin the temperature should start to drop thanks to the added cloud cover. We'll see sct'd showers and storms today with a likely rain chance of Friday. For the weekend rain chances will once again stay scattered in nature and will stay that way for the first half of next week. - Jeff Morrow & Diane Deaton / WAFB Storm Team
