ELECTRICAL SUBSTATION RELIABILITY EVALUATION WITH EMPHASIS ON EVOLVING INTERDEPENDENCE ON COMMUNICATION INFRASTRUCTURE.
The objective of this study is to develop a methodology for a probabilistic assessment of the reliability and security of electrical energy distribution networks. This includes consideration of the future grid system, which will rely heavily on the existing digitally based communication infrastructure for monitoring and protection. Another important objective of this study is to provide information and insights from this research to Consolidated Edison Company (Con Edison) that could be useful in the design of the new network segment to be installed in the area of the World Trade Center in lower Manhattan. Our method is microscopic in nature and relies heavily on the specific design of the portion of the grid being analyzed. It extensively models the types of faults that a grid could potentially experience, the response of the grid, and the specific design of the protection schemes. We demonstrate that the existing technology can be extended and applied to the electrical grid and to the supporting communication network. A small subsection of a hypothetical grid based on the existing New York City electrical grid system of Con Edison is used to demonstrate the methods. Sensitivity studies show that in the current design the frequency for the …

Exotic physics: search for doubly-charged higgs bosons decaying to dileptons in p anti-p collisions at s**(1/2) = 1.96 tev
The authors present the results of a search for doubly-charged Higgs bosons (H{sup {+-}}{sup {+-}}) decaying to dileptons (ll') using {approx} 240 pb{sup -1} of p{bar p} collision data collected by the CDF II experiment at the Fermilab Tevatron. In the search region, given by same-sign ll' mass m{sub ll'} > 80 GeV/c{sup 2} (100 GeV/c{sup 2} for ee channel), they observe no evidence for H{sup {+-}}{sup {+-}} production. They set limits on {sigma}(p{bar p} {yields} H{sup ++}H{sup --} {yields} l{sup +}l'{sup +}l{sup -}l'{sup -}) as a function of the mass of the H{sup {+-}}{sup {+-}} and the chirality of its couplings. Assuming exclusive same-sign dilepton decays, they derive lower mass limits on H{sub L}{sup {+-}}{sup {+-}} of 133 GeV/c{sup 2}, 136 GeV/c{sup 2}, and 115 GeV/c{sup 2} in the ee, {mu}{mu}, and e{mu} channels, respectively, and a lower mass limit of 113 GeV/c{sup 2} on H{sub R}{sup {+-}}{sup {+-}} in the {mu}{mu} channel, all at the 95% confidence level.

Centrality and pseudorapidity dependence of charged hadron production at intermediate p{sub T} in Au+Au collisions at {radical}s{sub NN} = 130 GeV
We present STAR measurements of charged hadron production as a function of centrality in Au + Au collisions at {radical}s{sub NN} = 130 GeV. The measurements cover a phase space region of 0.2 < p{sub T} < 6.0 GeV/c in transverse momentum and -1 < {eta} < 1 in pseudorapidity. Inclusive transverse momentum distributions of charged hadrons in the pseudorapidity region 0.5 < |{eta}| < 1 are reported and compared to our previously published results for |{eta}| < 0.5. No significant difference is seen for inclusive p{sub T} distributions of charged hadrons in these two pseudorapidity bins. We measured dN/d{eta} distributions and truncated mean p{sub T} in a region of p{sub T} > p{sub T}{sup cut}, and studied the results in the framework of participant and binary scaling. No clear evidence is observed for participant scaling of charged hadron yield in the measured p{sub T} region. The relative importance of hard scattering process is investigated through binary scaling fraction of particle production.

Boundary Layer Cloudiness Parameterizations Using ARM Observations
This study used DOE ARM data and facilities to: (1) study macroscopic properties of continental stratus clouds at SGP and the factors controlling these properties, (2) develop a scientific basis for understanding the processes responsible for the formation of boundary layer clouds using ARM observations in conjunction with simple parametric models and LES, and (3) evaluate cumulus cloud characteristics retrieved from the MMCR operating at TWP-Nauru. In addition we have used high resolution 94 GHz observations of boundary layer clouds and precipitation to: (1) develop techniques for using high temporal resolution Doppler velocities to study large-eddy circulations and turbulence in boundary layer clouds and estimate the limitations of using current and past MMCR data for boundary layer cloud studies, (2) evaluate the capability and limitations of the current MMCR data for estimating reflectivity, vertical velocities, and spectral under low- signal-to-noise conditions associated with weak no n-precipitating clouds, (3) develop possible sampling modes for the new MMCR processors to allow for adequate sampling of boundary layer clouds, and (4) retrieve updraft and downdraft structures under precipitating conditions.

Oral History Interview with Albert Albritton, June 15, 2004
The National Museum of the Pacific War presents an interview with Albert Albritton. Albritton joined the Navy in 1937. He served aboard the USS Dobbin (AD-3). They were present during the attack on Pearl Harbor on 7 December 1941. At the time of the attack the Dobbin was moored northeast of Ford Island. After the attack, they picked up survivors and took the wounded to shore. Albritton participated in the Korean War and was discharged in 1957.

VELOCITY BUNCHING OF HIGH-BRIGHTNESS ELECTRON BEAMS
Velocity bunching has been recently proposed as a tool for compressing electron beam pulses in modern high brightness photoinjector sources. This tool is familiar from earlier schemes implemented for bunching dc electron sources, but presents peculiar challenges when applied to high current, low emittance beams from photoinjectors. The main difficulty foreseen is control of emittance oscillations in the beam in this scheme, which can be naturally considered as an extension of the emittance compensation process at moderate energies. This paper presents two scenarios in which velocity bunching, combined with emittance control, is to play a role in nascent projects. The first is termed ballistic bunching, where the changing of relative particle velocities and positions occur in distinct regions, a short high gradient linac, and a drift length. This scenario is discussed in the context of the proposed ORION photoinjector. Simulations are used to explore the relationship between the degree of bunching, and the emittance compensation process. Experimental measurements performed at the UCLA Neptune Laboratory of the surprisingly robust bunching process, as well as accompanying deleterious transverse effects, are presented. An unanticipated mechanism for emittance growth in bends for highly momentum chirped beam was identified and studied in these experiments. The …

Europe and Counterterrorism: Strengthening Police and Judicial Cooperation
The September 11, 2001 terrorist attacks on the United States gave new momentum to European Union (EU) initiatives to combat terrorism and other crossborder crimes such as drug trafficking, human trafficking, and financial fraud. For many years, EU efforts to address such challenges were hampered by national sovereignty concerns, insufficient resources, and a lack of trust among law enforcement agencies. However, the terrorist attacks and the subsequent revelation of Al Qaeda cells in Europe changed this status quo as it became increasingly evident that the EU’s open borders and different legal systems allowed terrorists and other criminals to move around easily and evade arrest and prosecution. Thus, EU officials renewed their efforts to harmonize national laws and bring down traditional barriers among member states’ police, intelligence, and judicial authorities. As part of this initiative, the EU has also sought to enhance ongoing cooperation with U.S. law enforcement and judicial authorities so that information can be meaningfully shared and suspects apprehended expeditiously.

Heavy Meson Production at a Low-Energy Photon Collider
A low-energy {gamma}{gamma} collider has been discussed in the context of a testbed for a {gamma}{gamma} interaction region at the Next Linear Collider(NLC). We consider the production of heavy mesons at such a testbed using Compton-backscattered photons and demonstrate that their production rivals or exceeds those by BELLE, BABAR or LEP where they are produced indirectly via virtual {gamma}{gamma} luminosities.
