Lecture archiving on a larger scale at the University of Michigan and CERN
The ATLAS Collaboratory Project at the University of Michigan has been a leader in the area of collaborative tools since 1999. Its activities include the development of standards, software and hardware tools for lecture archiving, and making recommendations for videoconferencing and remote teaching facilities. Starting in 2006 our group became involved in classroom recordings, and in early 2008 we spawned CARMA, a University-wide recording service. This service uses a new portable recording system that we developed. Capture, archiving and dissemination of rich multimedia content from lectures, tutorials and classes are increasingly widespread activities among universities and research institutes. A growing array of related commercial and open source technologies is becoming available, with several new products introduced in the last couple years. As the result of a new close partnership between U-M and CERN IT, a market survey of these products was conducted and a summary of the results are presented here. It is informing an ambitious effort in 2009 to equip many CERN rooms with automated lecture archiving systems, on a much larger scale than before. This new technology is being integrated with CERN's existing webcast, CDS, and Indico applications.

University of Michigan lecture archiving and related activities of the U-M ATLAS Collaboratory Project
Large scientific collaborations as well as universities have a growing need for multimedia archiving of meetings and courses. Collaborations need to disseminate training and news to their wide-ranging members, and universities seek to provide their students with more useful studying tools. The University of Michigan ATLAS Collaboratory Project has been involved in the recording and archiving of multimedia lectures since 1999. Our software and hardware architecture has been used to record events for CERN, ATLAS, many units inside the University of Michigan, Fermilab, the American Physical Society and the International Conference on Systems Biology at Harvard. Until 2006 our group functioned primarily as a tiny research/development team with special commitments to the archiving of certain ATLAS events. In 2006 we formed the MScribe project, using a larger scale, and highly automated recording system to record and archive eight University courses in a wide array of subjects. Several robotic carts are wheeled around campus by unskilled student helpers to automatically capture and post to the Web audio, video, slides and chalkboard images. The advances the MScribe project has made in automation of these processes, including a robotic camera operator and automated video processing, are now being used to record ATLAS Collaboration events, making them available more quickly than before and enabling the recording of more events.

Measurement of the Depolarization Parameter in Elastic Proton Proton Scattering at 3 and 6-GeV/c
Results are presented from an experiment designed to make the first systematic study of the depolarization parameter in elastic proton--proton scattering at high energies. Measurements were made at 3.0 and 6.0 GeV/c at abs. value t values extending to 1.7 (GeV/c)2 at the higher momentum. A high- intensity unpolarized proton beam was incident on a polarized proton target and the polarization of the elastically scattered recoil protons was determined with a carbon analyzer. The results are discussed in the framework of optical and exchange models.

Lambda/b polarization study in the ATLAS experiment.
From preliminary studies it has been estimated that approximately 75000Λb will be available in the first years of the ATLAS running with integrated luminosity of 30fb−1, and we will be able to measure the polarization with accuracy of about 2%. In this paper we present the technical feasibility of measuring the polarization of Λb hyperons in ATLAS experiment.

Status of the Compact Muon Solenoid Detector at the Large Hadron Collider
The Compact Muon Solenoid (CMS) detector is being constructed at the Large Hadron Collider (LHC) at CERN for the purpose of exploring new physics in proton‐proton collisions at 14 TeV. The detector is to be designed, constructed and commissioned in time for the start of the LHC in April 2007. This article summarizes the current status of the detector and foreseen program for completion.

Monolithic CMOS Pixel Detectors for ILC Vertex Detection
A CMOS pixel vertex detector suited for use at the International Linear Collider (ILC) is proposed. The proposed detector consists of 50µm ◊ 50µm macropixels, each with integrated bunch clock memory, on top of 5µm ◊ 5µm micropixels that record amplitude information. The micropixels integrate over all bunch crossing in a train. Using the time recorded by the macropixels, the fine position measurements made in the micropixels can be associated to only a few of the 3000 bunch crossings in a bunch train.

Validating Geant4 Versions 7.1 and 8.3 Against 6.1 for BaBar
Since 2005 and 2006, respectively, Geant4 versions 7.1 and 8.3 have been available, providing: improvements in modeling of multiple scattering; corrections to muon ionization and improved MIP signature; widening of the core of electromagnetic shower shape profiles; newer implementation of elastic scattering for hadronic processes; detailed implementation of Bertini cascade model for kaons and lambdas, and updated hadronic cross-sections from calorimeter beam tests. The effects of these changes in simulation are studied in terms of closer agreement of simulation using Geant4 versions 7.1 and 8.3 as compared to Geant4 version 6.1 with respect to data distributions of: the hit residuals of tracks in BABAR silicon vertex tracker; the photon and KOL shower shapes in the electromagnetic calorimeter; the ratio of energy deposited in the electromagnetic calorimeter and the flux return of the magnet instrumented with a muon detection system composed of resistive plate chambers and limited-streamer tubes; and the muon identification efficiency in the muon detector system of the BaBar detector.

RECENT RESULTS ON CP-VIOLATION AT THE BABAR AND BELLE B-FACTORIES
New results on CP violation measurements performed on events collected at the Υ(4S) in upto 432 fb-1 of data at the BABAR experiment and upto 770 fb-1 of data collected at the Belle experiment. The measurements provide new constraints on the unitarity triangle angles γ and β. The measurements presented include: results from BABAR and Belle on CPV using Dalitz plot analyses, measurements of the CKM angle γ using a GLW analysis of B → DK± decays and from using B → D*°K- decays and results on yCP using D° mixing.
