We report compressibility data on single-domain, globular proteins which suggest a general relationship between protein conformational transitions and delta kzeroS, the change in the partial specific adiabatic compressibility which accompanies the transition. Specifically, we find transitions between native and compact intermediate states to be accompanied by small increases in kzeroS of +(1-4)...

Recent observations from the Spitzer Space Telescope enable us to study the mid-infrared dust excess of Asymptotic giant branch (AGB) stars in the Large Magellanic Cloud (LMC). Using mid-infrared spectra, together with photometric data from the SAGE programme, we establish a colour selection of carbon-rich AGB stars with intermediate and high mass-loss rates. We also established mass-loss rate ...

Motivated by the recent discovery of a charmonium $X(3960)$ in $B$ decays LHCb Collaboration, likely existence two bound/virtual states (denoted $ X_{s\bar{s}}$ and X_{q\bar{q}}$) below $D_{s}^{+}D_{s}^{-}$ $\bar{D}D$ mass thresholds has been re-examined recently. In this work, we employ effective Lagrangian approach to calculate their production rates utilizing triangle diagrams. Our results s...

A sinusoidal grating can be viewed as a series of light and dark bars. Here we measure the contrast discrimination thresholds for light and dark bars individually, and find that the contrast discrimination thresholds for the whole sinusoid can be explained as ideal summation of the light and dark bar thresholds. We propose a model for light bar, dark bar, and sinusoidal contrast discrimination ...

Introduction. Partial or complete physeal arrest with formation of a bony bridge, or bar, between two cartilaginous segments is frequently observed in pediatric disorders. Bone bar formation may lead to angular deformity and/or limb-length discrepancy [1]. Plain radiographs are used to evaluate bar formation, but image interpretation is difficult due to the irregular three-dimensional (3D) shap...

We study the LHC sensitivity to new broad neutral resonances produced in two-photon fusion and decaying a top quark pair, $\gamma\gamma \to t\bar{t}$. This is probed central exclusive $t\bar{t}$ production proton-proton collisions, $pp p t\bar{t} p$. use tagging of intact protons by PPS (CMS) AFP (ATLAS) consider semi-leptonic $t\bar t$ channel. The also mapped onto set dimension-8 t\bar{t}$ op...

Thermodynamic calculations for selected silicate-oxide-fluorite assemblages indicate that several commonly occurring fluorite-bearing assemblages are restricted to relatively narrow fo,-fF> fields at constant P-T. The presence of fayalite-ferrohedenbergite-fluorite-quartz *magnetite and ferrosalite-fluorite-quartz-magnetite assemblages in orthogneisses from Au Sable Forks, Wanakena and Lake Ple...

The effect of CO2 pressure on commercial S.cerevisiae cells viability and on the rate of ethanol production in yeast, has been studied in batch cultures under 1,10 and 18 bar of CO2 pressures. The results show that the effect of CO2 pressure on ethanol productivity strongly depends on the temperature, glucose and starting biomass concentration and pressure itself. Under atmospheric CO2 pressure...

I review the arguments for the importance of halo structure in driving galaxy evolution and coupling a galaxy to its environment. We begin with a general discussion of the key dynamics and examples of structure dominated by modes. We find that simulations with large numbers of particles (N ∼> 10 ) are required to resolve the dynamics. Finally, I will describe some new results which demonstrates...

Catecholamines play a central role in the regulation of energy expenditure, in part by stimulating lipid mobilization through lipolysis in fat cells. The beta-2 adrenoceptor (BAR-2) is a major lipolytic receptor in human fat cells. To determine whether known polymorphisms in codons 16, 27, and 164 of this receptor play a role in obesity and subcutaneous adipocyte BAR-2 lipolytic function, we in...
