SUNNYVALE, CA -- 3Dlabs(R), Inc. Ltd. (Nasdaq:TDDD) today announced that its next-generation Wildcat III 6110 graphics accelerators have been selected by Fujitsu Siemens Computers as the graphics subsystem for its high-end single processor workstation CELSIUS 444 and the dual-capable Intel Xeon processor-based CELSIUS 670 workstation. The Wildcat III 6110 will be integrated into the CELSIUS workstations, while the Wildcat 6210 will be available as an upgrade option from authorized Fujitsu Siemens VARs.

Today the LHC circulated two beams simultaneously for the first time, allowing the operators to test the synchronization of the beams and giving the experiments their first chance to look for proton-proton collisions. With just one bunch of particles circulating in each direction, the beams can be made to cross in up to two places in the ring. From early in the afternoon, the beams were made to cross at points 1 and 5, home to the ATLAS and CMS detectors, both of which were on the look out for collisions. Later, beams crossed at points 2 and 8, ALICE and LHCb. Screens showing two beams in the LHC

“It’s a great achievement to have come this far in so short a time,” said CERN Director General Rolf Heuer. “But we need to keep a sense of perspective – there’s still much to do before we can start the LHC physics programme.”

Beams were first tuned to produce collisions in the ATLAS detector, which recorded its first candidate for collisions at 14:22 this afternoon. Later, the beams were optimised for CMS. In the evening, ALICE had the first optimization, followed by LHCb.

“This is great news, the start of a fantastic era of physics and hopefully discoveries after 20 years' work by the international community to build a machine and detectors of unprecedented complexity and performance," said ATLAS spokesperson, Fabiola Gianotti.

“The events so far mark the start of the second half of this incredible voyage of discovery of the secrets of nature,” said CMS spokesperson Tejinder Virdee.

“It was standing room only in the ALICE control room and cheers erupted with the first collisions” said ALICE spokesperson Jurgen Schukraft. “This is simply tremendous.”

“The tracks we’re seeing are beautiful,” said LHCb spokesperson Andrei Golutvin, “we’re all ready for serious data taking in a few days time.”

These developments come just three days after the LHC restart, demonstrating the excellent performance of the beam control system. Since the start-up, the operators have been circulating beams around the ring alternately in one direction and then the other at the injection energy of 450 GeV. The beam lifetime has gradually been increased to 10 hours, and today beams have been circulating simultaneously in both directions, still at the injection energy.

Next on the schedule is an intense commissioning phase aimed at increasing the beam intensity and accelerating the beams. All being well, by Christmas, the LHC should reach 1.2 TeV per beam, and have provided good quantities of collision data for the experiments’ calibrations.

Two mathematicians from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have won prestigious prizes from the International Council for Industrial and Applied Mathematics (ICIAM) for groundbreaking work in applied math, with impacts ranging from fluid mechanics and aerodynamics to medical imaging and semiconductor manufacturing.Alexandre Chorin (left) and James Sethian

Alexandre Chorin won the 2011 ICIAM Lagrange Prize in recognition of his fundamental and original contributions to applied mathematics, fluid mechanics, statistical mechanics, and turbulence modeling. The Lagrange Prize provides international recognition to mathematicians who have made an exceptional contribution to applied mathematics throughout their career.

James Sethian won the 2011 ICIAM Pioneer Prize for his fundamental methods and algorithms that have had a large impact in imaging and shape recovery in medicine, geophysics and tomography, and drop dynamics in inkjets. The Pioneer Prize recognizes pioneering work introducing applied mathematical methods and scientific computing techniques to an industrial problem area or a new scientific field.

The awards, announced today by the ICIAM, bring to Berkeley Lab two of the five math prizes the organization awards every four years. The ICIAM is composed of many of the national and international associations of professional mathematicians concerned with applications.

Chorin is a senior scientist with the Mathematics Group of Berkeley Lab’s Computational Research Division and a University Professor of mathematics at the University of California, Berkeley. Sethian heads the Mathematics Group of Berkeley Lab’s Computational Research Division and is a professor of mathematics at the University of California, Berkeley. They are two of the world’s foremost applied mathematicians and have spent most of their careers at Berkeley.

“These awards recognize the immense influence that Alexandre’s and James’ research has had on applied math as well as many scientific disciplines and industrial applications,” says Horst Simon, Deputy Director of Berkeley Lab. “The awards are also a testament to Berkeley Lab’s worldwide leadership in applied math, benefitting society and solving some of our most urgent scientific challenges.”

Chorin’s contributions span computational mathematics, fluid mechanics, statistical mechanics, and turbulence

In a career that spans nearly 50 years, Chorin introduced mathematical and computational methods for solving problems in science and engineering. He has applied his methods to understanding water flow in oceans and lakes, flow in turbines and engines, combustion, and blood flow in the heart and veins.

He invented techniques in the mid 1960s that were the first practical and accurate methods for approximating the full Navier–Stokes equations, which stand at the basis of the most popular codes in computational fluid mechanics.

Chorin followed this with the invention and design of vortex methods, for which he was given the U.S. National Academy of Sciences Award in Applied Mathematics and Numerical Analysis in 1989. These techniques made possible the modeling of the complex mixing and instabilities of turbulent flow.

More recently, Chorin developed methods for distilling fundamental properties buried in noisy and uncertain data. One application is designed to extract biological information from satellite imagery of the ocean.

The ICIAM news release states, “Beginning with his pioneering work 40 years ago, Chorin developed some of the key mathematical and algorithmic ideas that underlie many of the most powerful computer codes in computational fluid dynamics, by blending mathematical intuition, physical insight and a deep attention to practical implementation.”

His many awards include Norbert Wiener Prize in Applied Mathematics from the American Mathematical Society and the Society for Industrial and Applied Mathematics, which he received in 2000. He was honored with the title of University Professor by the Regents of the University of California in 2002. He is a member of the National Academy of Sciences and a fellow of the American Academy of Arts and Sciences.

Chorin, 72, was born in Poland and grew up Israel and Switzerland. He received his PhD from the Courant Institute of New York University in 1966 and joined Berkeley Lab in 1975.

 

Sethian’s contributions range from fluid interfaces to computer chips

For the past three decades, Sethian has built mathematical and computational tools to tackle pressing problems in fields such as medical imaging, seismic imaging, combustion calculations, computer chip manufacturing, and inkjet printing.

The broad reach of his applications stem from his pioneering work on the computer representation of the motion of curves, surfaces, interfaces, and wave fronts, for which he was awarded the Norbert Wiener Prize in 2004.

According to the ICIAM news release announcing the award, the level set method pioneered by Sethian and Stanley Osher has had a major impact in a wide range of fields and is one of the most used algorithms of the past few decades.

Sethian’s mathematical algorithms for modeling etching and deposition in the manufacture of computer chips are now an indispensable part of industrial semiconductor fabrication simulations throughout the world.

Sethian’s algorithms for imaging and shape recovery are found throughout medical and biological imaging technologies, including imaging workstations that quantify cardiac motion and efficiency.

He developed tools for solving Hamilton–Jacobi equations with applications in geophysics and tomography, currently in use by the petroleum industry. He also developed numerical methods for inkjet dynamics and combustion processes.

The ICIAM news release adds, “This extraordinary range of successes is made possible by Sethian’s unparalleled eagerness to learn thoroughly the engineering aspects of problems he works on, the accuracy and depth of his feeling for mathematical structure, and his broad mathematical knowledge. His body of work is emblematic of what an applied mathematician should aspire to achieve.”

Sethian, 56, was born in Washington, D.C. He earned his PhD in Applied Mathematics from the University of California, Berkeley in 1982 and joined Berkeley Lab in 1985. He is a member of the National Academy of Engineering.

The prizes will be awarded at the International Congress for Industrial and Applied Mathematics next July in Vancouver, Canada.

Chorin’s and Sethian’s research has been funded in part by the Department of Energy’s Applied Mathematics program, which is part of the Office of Advanced Scientific Computing Research.

Daniel Pedro knew when he was a sophomore at Santa Fe Indian School that he wanted to be an anthropologist. He also knew that as a Zuni, he would not be able to touch human remains – a common task for physical anthropologists.

“It was kind of a barrier,” said Pedro, a 20-year-old freshman at the University of New Mexico-Gallup. “I had to find a way to work around it.”

Pedro began to look for that way through his participation in the New Mexico Supercomputing Challenge. The Challenge aims to teach teams of middle and high schools students how to use powerful computers to analyze, model and solve real world problems and awards prizes in various categories.

Pedro hit on the idea of studying the faces of living puebloans in search of consistent similarities and then projecting that data onto the past as a way to identify and repatriate skeletal remains. As stated in the executive summary of his project, “My goal … is to make it easier for anthropologists to figure out which tribe/pueblo the remains belong to on the computer, instead of disrespecting Native customs and damaging the skull.”

An early advisor, UNM Curator of Human Osteology Heather Edgar, told Pedro that the people of the pueblos, both present and past, were too mixed to make the sort of determinations he was seeking. Nevertheless, she was impressed by his inventive approach to problem solving, and encouraged him by giving advice on how to go about his project. She also gave him a medical diagram of a human skull with which to start his studies.

“We need a Native perspective in anthropology, and especially a perspective that comes from working with living communities,” Edgar said.

Pedro’s unique project soon attracted several other advisors and mentors.

“They were impressed by the fact it was a student who wanted to do this kind of work, and a high school student and a Native American at that,” Pedro said.

Pedro began to work in a computer program called StarLogo, which allowed him to rotate two objects side by side and compare the objects in different profiles.  He had decided to concentrate on the human skull, comparing shapes that represented skulls. His goal was to create a method for anthropologists to determine which tribe or pueblo a skull might belong to with only minimal handling. The result was an entry for the Supercomputing Challenge called “Scan of the Past.”

“He learned a lot about the mathematics of 3D computer graphics and the rotation and scaling of 3D objects on the computer,” said Irene Lee, who oversees a grant program at Santa Fe Institute, and was previously lead facilitator for the SFI-MIT Adventures in Modeling program in Santa Fe when she worked with Pedro.

For this phase of his project, he received the Judges’ Choice Award for “Integrating Computation into Anthropology” from the Supercomputing Challenge.

The second phase of his work was on a new version of the “Scan of the Past,” with the help of Steve Guerin of Redfish Group, a Santa Fe-based business that specializes in data mining and visualizing. Guerin helped Pedro during his senior year construct a proxy data set, which would allow him to practice clustering techniques and classification algorithms, or in other words, construct real world data. Pedro learned how to integrate actual facial data collected after he photographed and studied 15 landmarks on the faces of 45 individuals – fellow students whom he persuaded to participate in his project. Generally, says Edgar, studies are made with as many as 50 landmarks on a human skull, but because Pedro was concentrated on faces, his study was limited to far fewer.

Although this phase of the project did not earn an award, he did receive an award from the Supercomputing Challenge in 2008-2009 for creating a graphic poster and creating a logo.

“Daniel took on a computational challenge that was meaningful to him and his community,” Lee said. “He is a great role model of a self-directed student researcher. He found an interesting, unsolved problem he could address. He overcame many obstacles and persevered with the project over several years.”

“It was great to have help from so many mentors,” Pedro said. “I had wondered if my project would be taken seriously because this was something really new.”

After graduating from high school in 2008, Daniel went on to enroll in UNM-Gallup, where he is studying, among other subjects, anthropology with Teresa Wilkins, professor of anthropology. Last year, he got a taste of the museum work he hopes to make a career by working at A:shiwi A:wan Museum and Heritage Center in Zuni, where he learned how to care for exhibits and worked with the photo collection. He also got some good career experience this past summer by participating in the Conference on Archaeoastronomy of the American Southwest, Camp Verde, Ariz., where, with researcher Anna Sofaer, writer, artist and founder of the Solstice Project, he presented a poster on a new interactive computer model of the Chaco Canyon Sun Dagger site.

His work with Sofaer helped him see that Native Americans “did marvelous things,” and reinforced his idea that, when studying historic sites, “It’s best to listen to Native American oral traditions about what happened at these sites. If we can integrate these traditions with what we can learn from modern technology, we can create another level of thinking.”

As Pedro continues his journey toward a bachelor’s degree in Southwest Studies at UNMG, and beyond, to a Ph.D., the intention that inspired his high school project will be very much with him. He wants to continue to explore ways to use technology to repatriate human remains and relics to the tribes they belong to. At the same time, he wants to build on what he learned from his high school project and his work with the Solstice Project to bring computers into anthropological work in a way that will help Native Americans understand who they are.

“As an example, time may overtake the original Sun Dagger site and it will become part of nature, but a replica of the model will be there to teach how Native Americans used the solstice at Chaco, and how they measured time,” Pedro said.

Wilkins applauds Native students like Pedro who are looking to apply “sophisticated technology to [solve] real problems,” and echoes his hope that today’s Natives will become empowered to make their own identifications of remains in order to repatriate them. She also believes that such an applied approach to anthropology as Daniel Pedro’s project undertook may be “highly significant in empowering Native people to conduct their own research.”

Pedro also hopes his vocation as anthropologist will help show Native Americans that eventually, they should not have to take classes to “be native.” After all, he points out, most of the non-natives who have taught American Indians about their history and culture cannot have complete information because, “There is a limit as to how much we can share. Keeping the culture or religion with the community keeps our identity within the community, rather than having it spill out.” Ideally, he says, those studying and interpreting the research some day will be Natives who will not only share this knowledge with their communities, but also mediate what is shared with non-Natives.
