Hot Topics From BaBar Experiment
The authors search for a new light non-Standard Model CP-odd Higgs boson, A{sup 0}, decaying to {tau}{sup +}{tau}{sup -}, {mu}{sup +}{mu}{sup -}, and invisible in radiative decays of the {Upsilon}(2S) and {Upsilon}(3S). We search for the light scalar particle produced in single-photon decays of the {Upsilon}(3S) resonance through the process {Upsilon}(3S) {yields} {gamma}A{sup 0}, A{sup 0} {yields} invisible. We also search for evidence of an undetectable {Upsilon}(1S) decay recoiling against the dipion system. The data samples contain 99 x 10{sup 6} {Upsilon}(2S) and 122 x 10{sup 6} {Upsilon}(3S) decays collected by the BABAR detector at the SLAC PEP-II B factory.

Impedance Scaling for Small Angle Transitions
Based on the parabolic equation approach to Maxwell's equations we have derived scaling properties of the high frequency impedance/short bunch wakefields of structures. For the special case of small angle transitions we have shown the scaling properties are valid for all frequencies. Using these scaling properties one can greatly reduce the calculation time of the wakefield/impedance of long, small angle, beam pipe transitions, like one often finds in insertion regions of storage rings. We have tested the scaling with wakefield simulations of 2D and 3D models of such transitions, and found that the scaling works well. In modern ring-based light sources one often finds insertion devices having extremely small vertical apertures (on the order of millimeters) to allow for maximal undulator fields reaching the beam. Such insertion devices require that there be beam pipe transitions from these small apertures to the larger cross-sections (normally on the order of centimeters) found in the rest of the ring. The fact that there may be many such transitions, and that these transitions introduce beam pipe discontinuities very close to the beam path, means that their impedance will be large and, in fact, may dominate the impedance budget of the entire ring. To reduce …

KANSAS WIND POWERING AMERICAN STATE OUTREACH: KANSAS WIND WORKING GROUP
The Kansas Wind Working Group (WWG) is a 33-member group announced by former Governor Kathleen Sebelius on Jan. 7, 2008. Formed through Executive Order 08-01, the WWG will educate stakeholder groups with the current information on wind energy markets, technologies, economics, policies, prospects and issues. Governor Mark Parkinson serves as chair of the Kansas Wind Working Group. The group has been instrumental in focusing on the elements of government and coordinating government and private sector efforts in wind energy development. Those efforts have moved Kansas from 364 MW of wind three years ago to over 1000 MW today. Further, the Wind Working Group was instrumental in fleshing out issues such as a state RES and net metering, fundamental parts of HB 2369 that was passed and is now law in Kansas. This represents the first mandatory RES and net metering in Kansas history.

Managing For Results: Opportunities to Strengthen Agencies' Customer Service Efforts
A letter report issued by the Government Accountability Office with an abstract that begins "The federal government has set a goal of providing service to the public that matches or exceeds that of the private sector. Executive Order 12862 (September 11, 1993) and a related 1995 memorandum require agencies to post customer service standards and report results to customers. As requested, this report (1) assesses the extent to which federal agencies are setting customer service standards and measuring related results, (2) assesses the extent to which agencies are reporting standards and results to customers and using the results to improve service, and (3) identifies some customer service management tools and practices used by various governments. The report also examines the steps the Office of Management and Budget (OMB) is taking to facilitate agency use of tools and practices. GAO surveyed 13 federal services among those with the most contact with the public, reviewed literature and interviewed agency officials as well as knowledgeable individuals in the area of customer service."

Massive Degeneracy and Goldstone Bosons: A Challenge for the Light Cone
Wherein it is argued that the light front formalism has problems dealing with Goldstone symmetries. It is further argued that the notion that in hadron condensates can explain Goldstone phenomena is false. This talk can be summarized as follows: (1) Exact symmetries can be realized in Wigner or Goldstone mode. (2) When a symmetry is realized in Wigner mode the states of the theory form degenerate irreducible representations of the symmetry group and the lowest energy state is unique. (3) When a symmetry is realized in Goldstone mode the lowest energy state of the theory is infinitely degenerate, the states of the theory do not form irreducible representations of the symmetry group and there are massless particles coupled by the conserved currents to any one of the possible ground states. (4) In finite volume the signal of a Goldstone realization of a symmetry is that the number of nearly degenerate states grows rapidly with increasing volume and the gap between these states shrinks exponentially with the volume. (5) The existence of a condensate such as the magnetization, for a ferromagnet, or the staggered magnetization for an anti-ferromagnet, signals a Goldstone symmetry. This is because this condensate transforms non-trivially under the …

Measurement of the Absolute Branching Fractions for $D^-_s\!\rightarrow\!\ell^-\bar{\nu}_{\ell}$ and Extraction of the Decay Constant $f_{D_s}$
The absolute branching fractions for the decays D{sub s}{sup -} {yields} {ell}{sup -}{bar {nu}}{sub {ell}} ({ell} = e, {mu}, or {tau}) are measured using a data sample corresponding to an integrated luminosity of 521 fb{sup -1} collected at center of mass energies near 10.58 GeV with the BABAR detector at the PEP-II e{sup +}e{sup -} collider at SLAC. The number of D{sub s}{sup -} mesons is determined by reconstructing the recoiling system DKX{gamma} in events of the type e{sup +}e{sup -}DKXD*{sub s}{sup -}, where D*{sub s}{sup -} {yields} D{sub s}{sup -}{gamma} and X represents additional pions from fragmentation. The D{sub s}{sup -} {yields} {ell}{sup 0}{nu}{sub {ell}} events are detected by full or partial reconstruction of the recoiling system DKX{gamma}{ell}. The branching fraction measurements are combined to determine the D{sub s}{sup -} decay constant f{sub D{sub s}} = (258.6 {+-} 6.4 {+-} 7.5) MeV, where the first uncertainty is statistical and the second is systematic.

New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy
Approximately ten percent of the energy consumed in U.S. commercial buildings is used by HVAC systems to condition outdoor ventilation air. Reducing ventilation rates would be a simple and broadly-applicable energy retrofit option, if practical counter measures were available that maintained acceptable concentrations of indoor-generated air pollutants. The two general categories of countermeasures are: 1) indoor pollutant source control, and 2) air cleaning. Although pollutant source control should be used to the degree possible, source control is complicated by the large number and changing nature of indoor pollutant sources. Particle air cleaning is already routinely applied in commercial buildings. Previous calculations indicate that particle filtration consumes only 10percent to 25percent of the energy that would otherwise be required to achieve an equivalent amount of particle removal with ventilation. If cost-effective air cleaning technologies for volatile organic compounds (VOCs) were also available, outdoor air ventilation rates could be reduced substantially and broadly in the commercial building stock to save energy. The research carried out in this project focuses on developing novel VOC air cleaning technologies needed to enable energy-saving reductions in ventilation rates. The minimum required VOC removal efficiency to counteract a 50percent reduction in ventilation rate for air cleaning systems …

Oral History Interview with Alvin Leos, October 27, 2010
Transcript of an oral interview with Alvin Leos. Leos quit school in the seventh grade to work on a dairy farm to help the family earn money during the Great Depression. He entered the Army in 1940 and was stationed at Galveston, Texas in a coast artillery unit when war was declared in December, 1941. Before long, his unit was assigned to coastal defense on New Hebrides. In 1944, he was sent back to the US where he trained recruits at Tyler, Texas. He then volunteered for a combat assignment and was attached to the First Cavalry Division prior to the invasion of the Philippines. Leos then describes patrols and enemy encounters on Luzon. When the war ended, Leos had enough points to go home. He eventually got assigned to the Second Armored Division at Fort Hood, Texas. Then, Leos discusses the time spent occupying Germany in the early 1950s. Leos moves back to discussing event that occurred while he was serving in the Philippines during WWII. He finishes by discussing visiting the National World War II Memorial in Washington, DC.

Oral History Interview with Robert Fuglaar, October 27, 2010
The National Museum of the Pacific War presents an oral interview with Robert Fuglaar. Fuglaar applied to join the Merchant Marine in 1942. He became an engineering cadet and journeyed by convoy to Liverpool, England. Fuglaar describes hearing the depth charge attacks by convoy escorts, heavy seas, and the amount of study that was required of a cadet. He also describes what it was like to work in an engine room. Fuglaar completed another convoy to England on another ship and then was assigned to two eventful convoys to the Soviet Union. He describes conditions in Murmansk. The Scharnhorst attempted to intercept one of the convoys and his ship ran aground on the other. Fuglaar became 3rd Assistant Engineer on another ship delivering supplies to Manila soon after its liberation. He was released by the Maritime Commission in March of 1945.

Plutonium complexation by phosphonate-functionalized mesoporous silica
MCM-41-type mesoporous silica functionalized with the CMPO-based 'Ac-Phos' silane has been reported in the literature (1) to show good capacity as an acftinide sorbent material, with potential applications in environmental sequestration, aqueous waste separation and/or vitrification, and chemical sensing of actinides in solution. The study explores the complexation of Pu(IV and VI) and other selected actinides and lanthanides by SBA-15 type mesoporous silica functionalized with Ac-Phos. The Pu binding kinetics and binding capacity were determined for both the Ac-Phos functionalized and unmodified SBA-15. They analyzed the binding geometry and redox behavior of Pu(VI) by X-ray absorption spectroscopy (XAS). They discuss the synthesis and characterization of the functionalized mesoporous material, batch sorption experiments, and the detailed analyses of the actinide complexes that are formed. Structural measurements are paired with high-level quantum mechanical modeling to elucidate the binding mechanisms.

QCD and Light-Front Holography
The soft-wall AdS/QCD model, modified by a positive-sign dilaton metric, leads to a remarkable one-parameter description of nonperturbative hadron dynamics. The model predicts a zero-mass pion for zero-mass quarks and a Regge spectrum of linear trajectories with the same slope in the leading orbital angular momentum L of hadrons and the radial quantum number N. Light-Front Holography maps the amplitudes which are functions of the fifth dimension variable z of anti-de Sitter space to a corresponding hadron theory quantized on the light front. The resulting Lorentz-invariant relativistic light-front wave equations are functions of an invariant impact variable {zeta} which measures the separation of the quark and gluonic constituents within the hadron at equal light-front time. The result is to a semi-classical frame-independent first approximation to the spectra and light-front wavefunctions of meson and baryon light-quark bound states, which in turn predict the behavior of the pion and nucleon form factors. The theory implements chiral symmetry in a novel way: the effects of chiral symmetry breaking increase as one goes toward large interquark separation, consistent with spectroscopic data, and the the hadron eigenstates generally have components with different orbital angular momentum; e.g., the proton eigenstate in AdS/QCD with massless quarks has …
