Conduction Effect of Thermal Radiation in a Metal Shield Pipe in a Cryostat for a Cryogenic Interferometric Gravitational Wave Detector

Posted by klaurent November 6, 2007Tokyo

Kavli Affiliate: Tomiyoshi Haruyama | Summary:A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational wave detector. The heat load was approximately 1000 times larger than the value calculated by the Stefan-Boltzmann law. We studied […]

Direct Amplification of Sound By Light

Posted by klaurent October 12, 2007MIT

Kavli Affiliate: Slawomir Gras | Summary:A new device, the opto-acoustic parametric amplifier (OAPA), is introduced, which is analogous to an optical parametric amplifier (OPA). The radiation pressure reaction of light on the reflective surface of an acoustic resonator provides nonlinearity similar to the Kerr effect in the OPA. The OAPA can be tuned to operate […]

Radio Detection of Neutrinos from Behind a Mountain

Posted by klaurent August 28, 2007Tokyo

Kavli Affiliate: Kai Martens | Summary:We explore the sensitivity of a neutrino detector employing strongly directional high gain radio antennae to detect the conversion of neutrinos above $10^16$ eV in a mountain or the earth crust. The directionality of the antennae will allow both, the low threshold and the suppression of background. This technology would […]

Systems level circuit model of C. elegans undulatory locomotion: mathematical modeling and molecular genetics

Posted by klaurent August 14, 2007Caltech

Kavli Affiliate: Paul W. Sternberg | Summary:To establish the relationship between locomotory behavior and dynamics of neural circuits in the nematode C. elegans we combined molecular and theoretical approaches. In particular, we quantitatively analyzed the motion of C. elegans with defective synaptic GABA and acetylcholine transmission, defective muscle calcium signaling, and defective muscles and cuticle […]

HiRes Estimates and Limits for Neutrino Fluxes at the Highest Energies

Posted by klaurent July 30, 2007Tokyo

Kavli Affiliate: Kai Martens | Summary:The High Resolution Fly’s Eye Experiment (HiRes) measures cosmic rays (CR) at the highest energies using the air fluorescence technique. As data taking on the Dugway Proving Grounds in Western Utah is finished, the HiRes data are relevant for cosmogenic neutrinos in two different ways. We first use our best […]

Current status of Japanese detectors

Posted by klaurent April 22, 2007Tokyo

Kavli Affiliate: Tomiyoshi Haruyama | Summary:Current status of TAMA and CLIO detectors in Japan is reported in this article. These two interferometric gravitational-wave detectors are being developed for the large cryogenic gravitational wave telescope (LCGT) which is a future plan for detecting gravitational wave signals at least once per year. TAMA300 is being upgraded to […]

The Use of Weighting in Periodicity Searches in All-Sky Monitor Data: Applications to the GLAST LAT

Posted by klaurent April 6, 2007Stanford

Kavli Affiliate: Richard Dubois | Summary:The light curves produced by all-sky monitors, such as the Rossi X-ray Timing Explorer All-Sky Monitor and the Swift Burst Alert Telescope (BAT), generally have non-uniform error bars. In searching for periodic modulation in this type of data using power spectra it can be important to use appropriate weighting of […]

Angle-resolved photoemission studies of lattice polaron formation in the cuprate Ca2CuO2Cl2

Posted by klaurent February 23, 2007Cornell

Kavli Affiliate: Kyle Shen | First 5 Authors: K. M. Shen, K. M. Shen, , , | Summary: To elucidate the nature of the single-particle excitations in the undoped parent cuprates, we have performed a detailed study of Ca2CuO2Cl2 using photoemission spectroscopy. The photoemission lineshapes of the lower Hubbard band are found to be well-described […]

Neutrino Physics around MeV Energies

Posted by klaurent December 25, 2006Tokyo

Kavli Affiliate: Kunio Inoue | Summary:We present a brief informative overview of a broad ranges of subjects, the solar, the reactor, the geo and the supernova neutrinos (but without excluding possible biases), the topics which consist of the session “Neutrino Physics around MeV Energies” in NOW2006. Contrary to the naive expectation, the field is found […]
