T heoretical and modeling assessments consistently point toward an increase in hurricane intensity with global warming (1–3). For the North Atlantic, the annual number of the most intense hurricanes has been predicted to increase by more than 50% for each 1-°C increase in surface temperatures (2, 4). However, there is no consensus on whether current hurricanes have responded to the substantial ...

The temperature of an extremal Reissner Nordstrom black hole is not restricted by the requirement of absence of a conical singularity. It is demonstrated how Kruskal-like coordinates may be constructed corresponding to any temperature whatsoever. A recently discovered stringy extremal black hole which apparently has an infinite temperature is also shown to have its temperature unrestricted by c...

This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...

Since the results in the literature are at considerable variance regarding leaf temperatures with reference to the surrounding air temperature, the writer thought it would be of interest to check some leaf temperatures in a different section of the country from those previously reported. The investigations of CURTIS (2) were performed at Berkeley and Riverside, California, and those of CLUM (1)...

Shock temperature measurements via optical pyrometry are being conducted on <100> single-crystal MgO preheated beftire compression to 1905-1924 K. Planar shocks were generated by impacting hot Mo(driver plate)-MgO targets with Mo or Ta flyers launched by the Caltech two-stage light-gas gun up to 6.6 km/s. Quasi-brightness temperature was measured with 2-3% uncertainty by a 6-channel optical pyr...

The microstructure in the surface layer of a pure iron plate was refined at the nanometer scale by means of a surface mechanical attrition treatment that generates repetitive severe plastic deformation of the surface layer. The subsequent nitriding kinetics of the treated iron with the nanostructured surface layer were greatly enhanced, so that the nitriding temperature could be as low as 300 d...
