The macroscopic magnetizations of a RuSr2(Eu0.7Ce0.3)2Cu2O101d sample were investigated. A ferromagnetlike transition occurs around TM in the low-field magnetization. Highly nonlinear M (H), non-Curie-Weiss susceptibility, and slow spin dynamics, however, were observed up to T1'(2 –3)TM . In addition, an antiferromagnetlike differential-susceptibility maximum of Ru appears around a separate tem...

Glial cell line-derived neurotrophic factor (GDNF) promotes PNS development and kidney morphogenesis via a receptor complex consisting of the glycerophosphatidylinositol (GPI)-anchored, ligand binding receptor GDNF family receptor α1 (GFRα1) and the receptor tyrosine kinase Ret. Although Ret signal transduction in vitro is augmented by translocation into lipid rafts via GFRα1, the existence and...

Transactional memory (TM) is a concurrency control mechanism that avoids common problems associated with conventional locking techniques. The correctness of concurrent programs employing a TM implementation depends on the correctness of the TM implementation. Therefore, it is important to ensure that the implementation satisfies correctness properties such as safety and liveness properties. Saf...

Tetrathiomolybdate (TM) is an orally active agent for treatment of disorders of copper metabolism. Here we describe how TM inhibits proteins that regulate copper physiology. Crystallographic results reveal that the surprising stability of the drug complex with the metallochaperone Atx1 arises from formation of a sulfur-bridged copper-molybdenum cluster reminiscent of those found in molybdenum a...

OBJECTIVES Wideband acoustic immittance (WAI) measurements are capable of quantifying middle ear performance over a wide range of frequencies relevant to human hearing. Static pressure in the middle ear cavity affects sound transmission to the cochlea, but few datasets exist to quantify the relationship between middle ear transmission and the static pressure. In this study, WAI measurements of ...

T h e effect of variable tree canopy cover, shadows, and topography on Thematic Mapper (TM) data was examined for blue oak (Quercus douglasii) woodland and wooded grassland on rugged terrain in central California. Thematic Mapper data were analyzed from September 1986 (trees in leaf, grass understory senescent) and December 1984 (trees leafless, grasses emerging. Tree cover measured in 84 60 m ...

The transmembrane (TM) domains of most membrane proteins consist of helix bundles. The seemingly simple task of TM helix bundle assembly has turned out to be extremely difficult. This is true even for simple TM helix bundle proteins, i.e., those that have the simple form of compact TM helix bundles. Here, we present a computational method that is capable of generating native-like structural mod...

We propose a new theoretical model for passively mobile Wireless Sensor Networks. We call it the PALOMA model, standing for PAssively mobile LOgarithmic space MAchines. The main modification w.r.t. the Population Protocol model [2] is that agents now, instead of being automata, are Turing Machines whose memory is logarithmic in the population size n. Note that the new model is still easily impl...

Recent progress in canopy bidirectional reflectance distribution function (BRDF) model inversions has allowed accurate estimates of vegetation biophysical characteristics from remotely sensed multi-angle optical data. Since most current BRDF inversion methods utilize one-dimensional (1-D) models, surface homogeneity within an image pixel is implied. The Advanced Very High Resolution Radiometer ...
