On-Shell Unitarity Bootstrap for QCD Amplitudes
Seeking and measuring new physics at the imminent Large Hadron Collider (LHC) will require extensive calculations of high-multiplicity backgrounds in perturbative QCD to next-to-leading order (NLO). The Les Houches 2005 workshop defined a target list, reproduced in table 1, for theorists to attack. In addition to the processes in the table, one would also like to compute processes such as W, Z + 4 jets, which are important backgrounds to searches for supersymmetry and other models of new electroweak physics. Such computations require one-loop amplitudes with seven external particles, including the vector boson, as depicted in figure 1. These are challenging calculations and Feynman-diagrammatic computations have only recently reached six-point amplitudes. Some of this progress has been described in this conference.

Public Release of a One Dimensional Version of the Photon Clean Method (PCM1D)
We announce the public release of a one dimensional version of the Photon Clean Method (PCM1D). This code is in the general class of 'inverse Monte Carlo' methods and is specifically designed to interoperate with the public analysis tools available from the Chandra Science Center and the HEASARC. The tool produces models of event based data on a photon by photon basis. The instrument models are based on the standard ARF and RMF fits files. The resulting models have a high number of degrees of freedom of order the number of photons detected providing an alternative analysis compared to the usual method of fitting models with only a few parameters. The original work on this method is described in ADASS 1996 (Jernigan and Vezie).

A Search for the Rare Leptonic B- to tau- anti-neutrino Recoiling against B+ to Decays to anti-D*0 l+ Lepton-neutrino
This thesis describes a search for the decay B{sup -} {yields} {tau}{sup -}{bar {nu}}{sub {tau}} in 231.8 x 10{sup 6} {Upsilon}(4S) decays recorded with the BABAR detector at the SLAC PEP-II B-Factory. A sample of events with one reconstructed exclusive semi-leptonic B decay (B{sup +} {yields} {bar D}*{sup 0} {ell}{sup +}{nu}{sub {ell}}) is selected, and in the recoil a search for B{sup -} {yields} {tau}{sup -} {bar {nu}}{sub {tau}} signal is performed in the following {tau} decay modes: {tau}{sup -} {yields} e{sup -}{bar {nu}}{sub e}{nu}{sub {tau}}, {tau}{sup -} {yields} {mu}{sup -}{bar {nu}}{sub {mu}}{nu}{sub {tau}}, {tau}{sup -} {yields} {pi}{sup -}{nu}{sub {tau}}, {tau}{sup -} {yields} {pi}{sup -}{pi}{sup 0}{nu}{sub {tau}}, and {tau}{sup -} {yields} {pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}}. They find no evidence of signal, and they set a preliminary upper limit on the branching fraction of {beta}(B{sup -} {yields} {tau}{sup -}{bar {nu}}{sub {tau}}) < 2.8 x 10{sup -4} at the 90% confidence level (CL). This result is then combined with a statistically independent BABAR search for B{sup -} {yields} {tau}{sup -}{bar {nu}}{sub {tau}} to give a combined preliminary limit of {Beta}(B{sup -} {yields} {tau}{sup -}{bar {nu}}{sub {tau}}) < 2.6 x 10{sup -4} at 90% CL.

A Structure at 2175 MeV in e+e- to \phif_0(980) Observed via Initial-State Radiation
We study the initial-state-radiation processes e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{gamma} and e{sup +}e{sup -} {yields} K{sup +}K{sup -} {pi}{sup 0}{pi}{sup 0}{gamma} using an integrated luminosity of 232 fb{sup -1} collected at the {Upsilon}(4S) mass with the BABAR detector at SLAC. Even though these reactions are dominated by intermediate states with excited kaons, we are able to study for the first time the cross section for e{sup +}e{sup -} {yields} {phi}(1020)f{sub 0}(980) as a function of center-of-mass energy. We observe a structure near threshold consistent with a 1{sup --} resonance with mass m=2.175 {+-} 0.010 {+-} 0.015 GeV/c{sup 2} and width {Lambda} = 58 {+-} 16 {+-} 20 MeV. We observe no Y (4260) signal and set a limit of {Beta}{sub Y{yields}{phi}{pi}{sup +}{pi}{sup -}} {center_dot} {Lambda}{sub ee}{sup Y} < 0.4 eV (90% confidence level), which excludes some models.

Z' Phenomenology and the LHC
A brief pedagogical overview of the phenomenology of Z{prime} gauge bosons is ILC in determining Z{prime} properties is also discussed. and explore in detail how the LHC may discover and help elucidate the models, review the current constraints on the possible properties of a Z{prime} nature of these new particles. We provide an overview of the Z{prime} studies presented. Such particles can arise in various electroweak extensions of that have been performed by both ATLAS and CMS. The role of the the Standard Model (SM). We provide a quick survey of a number of Z{prime}.

Application of atomic magnetometry in magnetic particledetection
We demonstrate the detection of magnetic particles carriedby water in a continuous flow using an atomic magnetic gradiometer.Studies on three types of magnetic particles are presented: a singlecobalt particle (diameter ~;150 mum, multi-domain), a suspension ofsuperparamagnetic magnetite particles (diameter ~;1 mum), andferromagnetic cobalt nanoparticles (diameter ~;10 nm, 120 kA/mmagnetization). Estimated detection limits are 20 mum diameter for asingle cobalt particle at a water flow rate 30 ml/min, 5x103 magnetiteparticles at 160 ml/min, and 50 pl for the specific ferromagnetic fluidat 130 ml/min. Possible applications of our method arediscussed.

The BBP Algorithm for Pi
The 'Bailey-Borwein-Plouffe' (BBP) algorithm for {pi} is based on the BBP formula for {pi}, which was discovered in 1995 and published in 1996 [3]: {pi} = {summation}{sub k=0}{sup {infinity}} 1/16{sup k} (4/8k+1 - 2/8k+4 - 1/8k+5 - 1/8k+6). This formula as it stands permits {pi} to be computed fairly rapidly to any given precision (although it is not as efficient for that purpose as some other formulas that are now known [4, pg. 108-112]). But its remarkable property is that it permits one to calculate (after a fairly simple manipulation) hexadecimal or binary digits of {pi} beginning at an arbitrary starting position. For example, ten hexadecimal digits {pi} beginning at position one million can be computed in only five seconds on a 2006-era personal computer. The formula itself was found by a computer program, and almost certainly constitutes the first instance of a computer program finding a significant new formula for {pi}. It turns out that the existence of this formula has implications for the long-standing unsolved question of whether {pi} is normal to commonly used number bases (a real number x is said to be b-normal if every m-long string of digits in the base-b expansion appears, in the …

Oral History Interview with Donald Austin, September 17, 2006
The National Museum of the Pacific War presents an interview with Donald Austin. Austin joined the Navy and was commissioned as an ensign before being assigned to the USS Pope (DD-225 in the Philippines. He was there when the war started. Austin was aboard the Pope when she was attacked and sunk. He was rescued by a Japanese destroyer and made a prisoner of war. He was held on Java and then Makassar. He was around when Richard Antrim intervened during a beating of a POW (Antrim was awarded the Medal of Honor). He shares several other POW anecdotes about their treatment, their daily lives, etc. in the camps. He also shares the experience of being liberated.

Oral History Interview with Janus Poppe, September 17, 2006
The National Museum of the Pacific War presents an interview with Dr. Janus Poppe. Poppe was born in the Netherlands in 1916. As a teenager, he worked as a mechanic for a ship building company. After high school, he attended a Dutch Marine academy for two years. In the mid-1930s, he served as a Deck Officer aboard a ship that traveled around the world twice. He later worked for a shipping company in the Dutch East Indies. In May of 1940, he was traveling in the middle of the Pacific when word arrived from his parents in Holland that the Germans had invaded. Poppe was then trained as a navigator and bombardier. He was serving as a navigator and bombardier aboard PBYs when Pearl Harbor was bombed. Poppe shares several recollections of his encounters with the Japanese during the war, and patrolling around Indonesia. He additionally oversaw 200 Dutch Marines, assigned to patrol and defend Parafield, South Australia. Around 1943, he completed military flight school at Fort Leavenworth in Kansas.
