Introducing a black hole's e ective temperature, we obtained an Honorable Mention in the 2012 Gravity Research Foundation Essay Competition interpreting black hole's quasi-normal modes naturally in terms of quantum levels. This permitted us to show that quantities which are fundamental to realize the underlying quantum gravity theory, like Bekenstein-Hawking entropy, its sub-leading corrections...

The decay characteristics of a mixed layer ocean passively coupled to an atmospheric model are important to the response of the climate system to stochastic or external forcing. We address here two salient features of such decay: the scale dependence of sea surface temperature anomaly (SSTA) decay timescales and the spatial inhomogeneities of SSTA decay modes. As expected, decay timescales incr...

We employ the method of comparison equations to study the propagation of a massless minimally coupled scalar field on the Schwarzschild background. In particular, we show that this method allows us to obtain explicit approximate expressions for the radial modes with energy below the peak of the effective potential which are fairly accurate over the whole region outside the horizon. This case ca...

We report on the low temperature growth, by molecular beam epitaxy (375 C) and electron-beam evaporation (300 C), of p-Ge films on n-Si substrates for fabricating p-n junction photodetectors, aimed at the integration of opto-electronic components with back-end Si CMOS processing. Various surface hydrogen and hydrocarbon removal treatments were attempted to improve device properties. We invoke G...

After a brief review of the description of black holes on branes, we examine the evaporation of a small black hole on a brane in a world with large extra dimensions. We show that, contrary to previous claims, most of the energy is radiated into the modes on the brane. This raises the possibility of observing Hawking radiation in future high energy colliders if there are large extra dimensions.

In the context of brane-world theories, the production cross-section for black holes may be greatly enhanced. Such black holes can in principle lead to detectable signals via their Hawking evaporation to brane-localized modes. We calculate, in the semiclassical approximation, the leading corrections to the energy spectrum (the greybody factors) for decay into scalar fields, as a function of the...

The authors discuss modifications to a simple linearmodel of intraseasonal moisturemodes.Wind–evaporation feedbacks were shown in an earlier study to induce westward propagation in an eastward mean low-level flow in this model. Here additional processes, which provide effective sources of moist static energy to the disturbances and which also depend on the low-level wind, are considered. Severa...

The evaporation of picoliter water and ethanol droplets generated by drop-on-demand inkjet printing was investigated on substrates with apparent contact angles between 10^{∘} and 135^{∘} and thermal conductivities between 0.25 and 149 Wm^{-1}K^{-1}. Drying times were calculated from a diffusion-limited model for droplets with both pinned and moving contact lines as a function of droplet diamete...

In this paper (III) we report real-time studies of the picosecond dynamics of iodine in Ne clusters IzNe,( Iz = 2-4) + IT + nNe. The results are discussed in relation to vibrational predissociation (VP), basic to the 1,X systems, and to the onset of intramolecular vibrational-energy redistribution (IVR). The latter process, which is a precursor for the evaporation of the host atoms or for furth...
