Thermal conformational changes in human serum albumin (HSA) in present with a 10 mM phosphate buffer, at pH=7 have been investigated via circular dichroism (CD) and UV spectroscopic methods. The results indicate that temperature in a range of 25oC to 55oC could induce a reversible conformational change in the structure of HSA. The HSA phase transition corresponds to the physiological and patho...

We develop the perturbation theory for bosons interacting via a weak two-body potential $V$, attractive and repulsive parts of which cancel each other. find that leading nonpairwise contribution to energy emerges in third order $V$ represents an effective three-body interaction, sign most cases (although not general) is anticorrelated with long-range tail $V$. apply our few particular interacti...

Using the standard Hartree-Fock approximation on the basis of the random-phase approximation, we calculate the self-energy induced by exchange scattering due to electron-electron interaction in a spin-polarized two-dimensional electron gas 2DEG system. Applying the exchange self-energy to a Green’s function approach, we examine how the exchange interaction affects the spin-splitting in a 2DEG w...

the aim of this research is to calculate the elastic constants and bulk modulus of cu-20 wt% ni random nanoalloy. the molecular dynamics simulation technique was used to calculate the mechanical properties in npt ensemble. the interaction between atoms as well as cohesive energy in the nanoalloy modeled systems was calculated by morse et al. two body potential. also the temperature of the syste...

Energy restriction reduces prostate tumor growth in transplantable tumor models in rodents, which suggests that excessive energy intake may contribute to the risk of prostate cancer. The association of total energy intake across the normal range with prostate cancer has not been consistent in epidemiological studies. We prospectively evaluated the joint associations of energy intake and body si...

The advent of smart phone has enabled health care anywhere and anytime. With pervasive health care, a person can perform necessary day to day tasks while his or her health is recorded, controlled, and processed continuously using on body sensors and actuators to capture abnormalities, trends, and causes. In such a scenario of utmost importance is seamless operation of the pervasive health manag...

This paper is a practice and experience paper on the use of a low cost motion capture system. We describe the integration of the Optitrack motion capture system with HALCA a hardware accelerated library for character animation in a Virtual Reality system called XVR. We demonstrate our system by mapping in real-time the tracked whole body motions of a person onto a virtual character which is vis...

Fluctuations associated with stretched E2 transitions from high spin levels in nuclei around 168 Yb are investigated by a cranked shell model extended to include residual two-body interactions. It is found that the gamma-ray energies behave like random variables and the energy spectra show the Poisson fluctuation, in the cranked mean field model without the residual interaction. With two-body r...

An ab anitio SCF-LCAO-MO study of nonadditive three-and four-body interaction energies in Mg 3 (equilateral and linear) and M84 (tetrahedral) clusters is presented. The relative importance of these few-body terms to the interaction energy is at most 39% for three-and 8% for four-body terms. This lies in marked contrast with the case of Be clusters where these terms can have a relative weight of...

The astronomical observations indicate that the universe expands with acceleration and it has a finite event horizon. The recent CMB observations confirm the universe is homogeneous, isotropic and asymptotically flat. The total gravitational energy of a body having mass m is the gravitational potential energy originating from the gravitational interaction of the body with all masses of the univ...
