| Resident Buffalo Given
Annual Medical Exams

The Roads & Ground crew gave a series of speedy medical exams on Tuesday to 50 kicking and bucking patients-- Fermilab's resident buffalo. In a process resembling a NASCAR pit stop, the buffalo (technically called American bison) were steered one by one through a series of gates to a screeching halt at the "squeeze chute," a metal chamber whose manually compressed walls hold the animal still.
The cantankerous buffalo can weigh up to 2000 pounds. While staged, they were injected with medications to prevent kidney and liver problems, diarrhea and parainfluenza, and given a dose of vitamins A, D and E. A squirt of deworming medication was spread on their backs, ear tags were cleaned or replaced and blood samples were taken to test for tuberculosis and other diseases. Some buffalo battled against the treatment, clanging their horns and heads against the metal bars. Others stayed still while huffing loudly through their nostrils. The front gate was lifted less than two minutes into each checkup and the freed buffalo dashed out of the holding chute. The hard part is tricking the buffalo into entering the staging system, said Mike Becker, head of Roads & Grounds. The buffalo food bunks were moved from the adjacent feeding grounds to the corral three weeks before the round-up. During Tuesday morning's feeding time, two stealth employees swung the gates shut as soon as all the animals were inside eating.
Although the round-up can be dangerous, Becker said this year's procedure went smoothly. "Everybody's got so much experience," he said. "You put people in places where they're comfortable and in something they've done before and rely on that experience." Later this month, half of the herd, 23 calves and two adults, will be sold at the annual auction, Becker said. They were separated from the rest of the herd after their checkups.

Science, Art, Advanced Networks Meet at iGrid 2005
"We only organize an iGrid when there's a new level of technology available," said Tom DeFanti, iGrid 2005 co-chair. "This workshop was organized because of the global availability of light paths. The goal of iGrid 2005 was to build a team that knows and trusts each other, and that knows how to control and request light paths for applications and users."

From The Seattle Times October 5, 2005: 2 Americans, German share physics Nobel Two Americans and a German were awarded the 2005 Nobel Prize in physics yesterday for theoretical research explaining how lasers work and for practical developments using lasers to explore the fine structures of atoms. Roy Glauber of Harvard University will receive half the $1.3 million prize for applying quantum theory to the light emitted by lasers, a feat that reconciled the dual nature of light, which can behave like both a particle and a wave. "You don't need Glauber's theory to invent the laser, but you do need it to understand its properties," said physicist Daniel Kleppner of the Massachusetts Institute of Technology.

| Getting Ready for Take 2: B0s Mixing at CDF |
||
| ||
|
CDF is making breakthrough strides in measuring special types of particles, neutral B mesons, which can spontaneously convert into their own antiparticles. This conversion process is periodic and is refered to as "flavor oscillations." The B mesons are bound states of a b quark and another type of quark, and include the B0s (anti-b quark plus s quark, pronounced "Bee sub s"), and the B0d (anti-b plus d, "Bee sub d"). So far nobody has directly seen B0s mesons oscillate and only lower limits on the mixing frequency have been derived. The observation of these rapid oscillations is one of the flagship analyses at the Tevatron which is presently the only place where B0s mesons are created in sufficiently large numbers. In March 2005, the CDF collaboration put out its first analysis based on Run II data in which a lower limit on the mixing frequency has been derived (see link ). To decide whether a B meson has oscillated the flavors of the B meson at its creation and decay time have to be determined. The decay flavor can be reconstructed from the particles measured in the detector. The production flavor is determined with "flavor tagging" algorithms. These algorithms are usually quite complex and are calibrated with B+ mesons (anti-b plus u, "Bee plus"), which cannot mix, and B0d mesons, which have a mixing frequency of at least 40 times lower than B0s mesons and have been studied in detail at the B factories. A group of physicists at CDF, partly shown in the photo, has just finished this important calibration step, performing a B0d mixing measurement. Since the March 2005 calibration, CDF has improved the analysis on various fronts to squeeze more information out of the data. The improvements are in the flavor tagging algorithms, and the additions of new decay channels of the B+ and B0d mesons. The improvement of the flavor taggers has increased the effective statistics of the data by 40 percent. The measured B0d mixing frequencies are in good agreement with the world average. Further major improvements for the B0s mixing analysis are under way; stay tuned for CDF's next B0s mixing result which is expected to appear soon. |
