Adsorption based on the immobilization of amino acids, i.e. leucine and glycine, on the surface of undoped polypyrrole (Ppy) is investigated. Calculations are done based on density functional theory using Gaussian03 software and applying GGA with 6-31G(d) basis set and exchange-correlation model of PBE (Perdew, Burke, Ernzerhof) level of theory. The energy of the Ppy doped with amino acids are ...

We generalize some results of Ford and Roman constraining the possible behaviors of the renormalized expected stressenergy tensor of a free massless scalar field in two dimensional Minkowski spacetime. Ford and Roman showed that the energy density measured by an inertial observer, when averaged with respect to the observers proper time by integrating against some weighting function, is bounded ...

the electronic structure, energy band structure and electronic density of 2 sno ceramic in cubicphase have been investigated using first principle full potential-linearized augmented plane wave (fp-lapw)method within density functional theory (dft). local density approximation (lda) and the generalizedgradient approximation (gga), which are based on exchange- correlation energy optimization wer...

Phase Change Memory (PCM) is a promising candidate of universal memory due to its non-volatility, high density and bit-alterability. However, high write energy consumption and limited endurance are two major challenges for its adoption in memory hierarchy. To address these challenges, one of the effective methods is to reduce write activities on PCM. This paper targets at PCMbased secondary sto...

well-designed lighting decreases accidents and diseases of eyes and can increase productivity and concentration. increase of energy price and a high proportion of electric lighting energy consumption in buildings due to defects in designing and maintenance led to desirable lighting to be reduced. one of our challenges in providing health and quality of lighting is lack of economic justification...

This paper proposed a new method to determine the neuronal tuning curves for maximum information efficiency by computing the optimum firing rate distribution. Firstly, we proposed a general definition for the information efficiency, which is relevant to mutual information and neuronal energy consumption. The energy consumption is composed of two parts: neuronal basic energy consumption and neur...
