We conducted a time-resolved photometric campaign of the helium dwarf nova, 2003aw in 2004 May– June. 2003aw stayed at 14.7–15.7 mag for the first several days during this campaign, which is the plateau phase of this superoutburst. This variable then rapidly decayed to ∼18.0 mag, still brighter by about 2 mag than its quiescence magnitude, and maintained this brightness for about 20 days, havin...

The magnetic field and pressure dependence of the magnetic ordering transition in Na x CoO 2 Abstract. We have measured the magnetic field (H≤90 kOe) and pressure (P≤10 kbar) dependence of the magnetic ordering temperature, T mag , in single crystal samples of Na x CoO 2 for a range of Na concentrations (0.60≤x≤0.72). We show that in zero field, T mag remains constant with decreasing x before m...

GAIA spectroscopic and radial velocity performancies are reviewed on the base of groundbased test observations and simulations. The prospects for accurate analysis of stellar atmospheres (temperature, gravity, chemical abundances, rotation, peculiarities) and precise radial velocities (single stars, binaries, pulsating stars) are colorful provided the spectral dispersion is high enough. A highe...

In recent years, Grid computing has emerged as a promising alternative to increase the capacity of processing and storage, through integration and sharing of multi-institutional resources. MAG (Mobile Agents for Grid Computing Environments)is a research project that explores the mobile agent paradigm as a way to overcome the design and implementation challenges of developing a Grid middleware. ...

We employ the very recent photometric data of the ogle project together with stellar atmosphere and linear pulsation models to determine the distance modulus of the Small Magellanic Cloud from its double-mode Cepheids. Based on the requirement of obtaining the same distance modulus DM from the two types of variables (fundamental & first overtone and first & second overtone), we get DM = 19.05 m...

Na+,K+ ATPase and myelin-associated glycoprotein (MAG) were studied by immunocytochemistry on paraffin sections of the spinal cord, optic nerve and trigeminal ganglion of adult control (+/+) and CNS myelin-deficient shiverer (shi/shi) mice. Immunostaining for Na+, K+-ATPase outlined the periphery of nerve fibers in the spinal cord white matter, optic nerve and trigeminal ganglion of +/+ and shi...

We present a photometric catalog of infrared (IR) sources based on the North Ecliptic Pole Wide field (NEP-Wide) survey of AKARI, which is an infrared space telescope launched by Japan. The NEP-Wide survey covered 5.4 deg2 area, a nearly circular shape centered on the NEP, using nine photometric filter-bands from 2−25 μm of the Infrared Camera (IRC). Extensive efforts were made to reduce possib...

Myelination increases neuronal conduction velocity through its insulating properties and an unidentified extrinsic effect that increases axonal caliber. Although it is well established that demyelination can cause axonal atrophy, the myelin molecule that regulates axonal caliber is not known. Loss of the structural proteins of compact peripheral nervous system (PNS) myelin, P0 protein, and myel...

with Anti-MAG/SGPG Antibody–Associated Neuropathy Sachiko Irie, MD, PhD,* Naomi Kanazawa, BS,† Mieko Ogino, MD, PhD,* Toyokazu Saito, MD, PhD,* and Tadao Funato, PhD‡ In a recent study by Yuki and colleagues, cytomegalovirus (CMV) DNA was detected in sera from 23 of 26 patients (88%) with IgM anti-myelin–associated glycoprotein (antiMAG)/sulfated glucuronyl paragloboside (SGPG) antibody– associ...

We present precise optical and near-infrared ground-based photometry of two Globular Clusters (GCs): ω Cen and 47 Tuc. These photometric catalogs are unbiased in the Red Giant Branch (RGB) region close to the tip. We provide new estimates of the RGB tip (TRGB) magnitudes— mI(TRGB) = 9.84± 0.05, ω Cen; mI(TRGB) = 9.46± 0.06, 47 Tuc—and use these to determine the relative distances of the two GCs...
