Poisson statistics predicts that the shot noise in a tunnel junction has a temperature independent third cumulant e(2)I, determined solely by the mean current I. Experimental data, however, show a puzzling temperature dependence. We demonstrate theoretically that the third cumulant becomes strongly temperature dependent and may even change sign as a result of feedback from the electromagnetic e...

Functionally graded materials, as a branch of new materials, have attracted increasing attention in recent years. A survey in the literature reveals the existence of wealth investigations on analysis of functionally graded material beams. Among them, Kang and Lee [1] presented explicit expressions for deflection and rotation of an FGM cantilever beam subjected to an end moment. Considering the ...

We combine classical molecular dynamics simulations and quantum density functional theory calculations to study the temperature effects on the electron affinity of the water octamer. The atomistic simulations provide a sample of the cluster's conformations as a function of the temperature, on which the density functional calculations are carried on. As the temperature increases, the cluster und...

A dramatic temperature dependent enhancement of U 5f spectral weight at EF is observed in angle-resolved photoemission measurements of URu2Si2 at the center of an X-point hole-pocket. Comparison of this temperature dependent behavior for excitation both at and below the U 5d→5f resonant threshold is presented.

Raman spectroscopy is a powerful non destructive technique for the characterization of carbon materials, and is a fundamental tool in the recent advances in the understanding of single wall carbon nanotubes (SWNTs). Raman experiments probe the optical phonons, allowing to assess the vibrational properties of the analyzed materials. A strong interplay exists between temperature (T ) and phonon f...

The opening-up of the magnetic field during solar eruptive events is often accompanied by a dimming of the local coronal emission. From observations of filament eruptions recorded with the Extreme-Ultraviolet Imager on STEREO during 2008–2009, it is evident that these dimmings are much more pronounced in 19.5 nm than in the lower-temperature line 17.1 nm, as viewed either on the disk or above t...

To unveil the mechanism of fast autooxidation of fish myoglobins, the effect of temperature on the structural change of tuna myoglobin was investigated. Purified myoglobin was subjected to preincubation at 5, 20, 50 and 40C. Overall helical structural decay through thermal treatment up to 95C was monitored by circular dichroism spectrometry, while the structural changes around the heme pocket w...

The sex of a reptile [6] embryo partly results from the production of sex hormones [7] during development, and one such process to produce those hormones [8] depends on temperature of the embryo's environment. The production of sex hormones [7] can result solely from genetics or from genetics in combination with the influence of environmental factors. In genotypic sex determination [9], also ca...
