The resistivity of ultraclean suspended graphene is strongly temperature (T) dependent for 50.5 x 10(11) cm(-2), the resistivity increases with increasing T and is linear above 50 K, suggesting carrier scattering from acoustic p...

Legionella pneumophila, the causative agent of Legionnaires' disease, was analysed by electron microscopy for production of surface structures. Crystalline surface (S-) layers and fimbriae were not detected, but monotrichous flagellation was seen. Polyclonal antibodies specific for the 47 kDa flagellin subunit of L. pneumophila Philadelphia I were used in Western blots to confirm the presence o...

Temperature-dependent photoluminescence (TDPL), one of the most effective and powerful optical characterisation methods, is widely used to investigate carrier transport and localized states in semiconductor materials. Resonant excitation and non-resonant excitation are the two primary methods of researching this issue. In this study, the application ranges of the different excitation modes are ...

I study derivative expansions of effective actions at finite temperature, illustrating how the standard methods are badly defined at finite temperature. I then show that by setting up the initial conditions at a finite time, these problems are solved. 1.1 Zero temperature I will work with a simple model of two real fields φ and η 1 L[φ, η] = 1 2 η∆ −1 η − 1 2 gφη 2 + L 0 [φ], (1) and integratin...

The establishment of localized auxin gradients plays a central role in developmental patterning in plants. Auxin levels and responses have been shown to increase with temperature although developmental patterning is not affected. This suggests the existence of a homeostatic mechanism that ensures that patterning occurs normally over a range of temperatures. We recently described the cloning and...

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...

Black phosphorus, also known as phosphorene in the few layer limit, is an almost unexplored “beyond graphene” material which is now considered a promising candidate for next-generation 2D FETs with good Ion/Ioff ratios [1-4]. One issue that has not been explored in detail yet is the hysteresis in the Id-Vg characteristics, which can severely limit the usability of these devices. Here we examine...

Recent experimental and theoretical studies show that the switching behavior of magnetic nanoparticles can be well controlled by external time-dependent magnetic fields. In this work, we inspect theoretically the influence of the temperature and the magnetic anisotropy on the spin-dynamics and the switching properties of single domain magnetic nanoparticles (Stoner-particles). Our theoretical t...

A recent experiment by Ma and collaborators shows that the gap anisotropy in Bi 2 Sr 2 Ca 1 Cu 2 O 8+x is strongly temperature dependent. In particular , the superconducting gap along the Γ − M direction shows a weaker temperature dependence than the gap along the Γ − X direction which decreases rapidly with temperature. We explain this novel feature as a natural consequence of the interlayer t...

Most terrestrial insect embryos support metabolism with oxygen from the environment by diffusion across the eggshell. Because metabolism is more temperature sensitive than diffusion, embryos should be relatively oxygen-limited at high temperatures. We tested whether survival, development time and metabolism of eggs of a moth, Manduca sexta, were sensitive to experimentally imposed variation in ...
