We discuss the finite temperature properties of ultracold bosons in optical lattices in the presence of an additional, smoothly varying potential, as in current experiments. Three regimes emerge in the phase diagram: a low-temperature Mott regime similar to the zero-temperature quantum phase, an intermediate regime where Mott insulator features persist, but where superfluidity is absent, and a ...

Carbon nanotubes (CNTs), nowadays, are one of the important nanomaterials that can be produce with different methods such as chemical vapor deposition (CVD). Growing of CNTs via CVD method can be influenced by several operating parameters that can affect their quality and quantity. In this article, the effects of inlet gas mixture temperature on CNT’s local growth rate, total production, and le...

We study a simplified model of the RNA molecule proposed by Vernizzi in the regime of strong concentration of positive ions in solution. The model considers a flexible chain of equal bases that can pairwise interact with any other one along the chain while preserving the property of saturation of the interactions. In the regime considered, we observe the emergence of a critical temperature Tc s...

Teneral adults of Dinoderus porcellus were raised in the laboratory and exposed to various temperature regimes 10, 15 20, 30, 35 and 40 C respectively. Four dried yam species Dioscorea rotundata, Dioscorea alata, Dioscorea dumetorum and Dioscorea cayenensis were used, to determine the effect of temperature on oviposition and developmental stages of the insect. At 10C, there was no oviposition, ...

We revisit the study of the phase structure of higher spin black holes carried out in arXiv: 1210.0284 using the “canonical formalism”. In particular we study the low as well as the high temperature regimes. We show that the Hawking-Page transition takes place in the low temperature regime. The thermodynamically favoured phase changes from conical surplus to black holes and then again to conica...

The efficiency of an AlGaN deep-ultraviolet light-emitting diode with peak emission wavelength of 285 nm is investigated as a function of current over a wide range of temperatures (110 K to 300 K). We find that the efficiency-versus-current curve exhibits unique and distinct features over the entire temperature range including three points of inflection. At low temperatures, the change in slope...

We consider the scaling of the mean square dipole moment in a plasma with logarithmic interactions in a two- and three-dimensional systems. In both cases, we establish the existence of a low-temperature regime where the mean square dipole moment does not scale with system size and a high-temperature regime where it does scale with system size. Thus, there is a nonanalytic change in the polariza...

The application of reach-through avalanche photodiodes (R’APD) as a photodetector for scintillator tiles has been investigated. The light collected by WLS fibers (0.84mm and 1mm diameter) embedded in the scintillator has been transmited to the 0.5mm active surface of APD by clear optical fibers and optical connectors. A low noise charge sensitive preamplifier (≈ 400e− equivalent noise charge) h...
