We study a model for photovoltaic energy collection consisting of Mott-insulating layer in presence acoustic phonons, coupled to two wide-band fermion leads at different chemical potentials and driven into nonequilibrium steady state by periodic electric field. treat electron correlations with dynamical mean-field theory using the so-called auxiliary master-equation approach as impurity solver ...

Phosphatidylinositol 4,5-bisphosphate (PIP2) plays a critical role in modulating the function of numerous ion channels, including large-conductance Ca(2+)- and voltage-dependent K(+) (BK, Slo1) channels. Slo1 BK channel complexes include four pore-forming Slo1 (α) subunits as well as various regulatory auxiliary subunits (β and γ) that are expressed in different tissues. We examined the molecul...

background: a set of hardware stereotactic radiosurgery is designed and constructed. the scope of this article is to describe how we have designed and developed stereotactic collimation assembly for a 9 mv neptun 10 pc linac. materials and methods: one collimator holder and six collimators were made, with their radiation field diameter between 12.5 mm to 25 mm at isocenter level. beam data, suc...

A method is proposed for describing the dynamics of systems interacting particles in terms an auxiliary field, which static mode equivalent to given interatomic potentials, and dynamic a classical relativistic composite field. It established that Fourier transform rational algebraic function wave vector, field composition elementary fields satisfy Klein-Gordon equation with complex masses. The ...

due to some important applications of guanine electrode in scientific and technology research such as electro-chemical dna based biosensors, and a problem of high redox potential of guanine (0.81 v), our research study concentrates on reducing guanine redox potential by substituting cu, ag, au, ch3, c2h5 and cl on sites of 1, 2 and 9 of guanine. a 5.0% reduction of redox potential for 9-ag-guan...

background: radiosurgery is a focal brain irradiation technique that delivers, usually in a single session, high dose of ionizing radiation. the presence of lateral electronic disequilibrium and steep dose gradients in small fields demands special attention to the selection of a suitable detector with respect to its size, composition and response. materials and methods : small circular fields w...

Introduction: Evoked potentials arisen by stimulating the brain can be utilized as a communication tool  between humans and machines. Most brain-computer interface (BCI) systems use the P300 component,  which is an evoked potential. In this paper, we evaluate the use of the hidden Markov model (HMM) for  detection of P300.  Materials and Methods: The wavelet transforms, wavelet-enhanced indepen...

Wing-diesel engine-powered hybrid ships can effectively reduce fuel consumption and CO2 emissions by using wind energy as the auxiliary driving power. The optimization management of system further improve ship's efficiency. To achieve this purpose, it is significant to establish an effective model for system. Therefore, established based on conversion analysis power in paper. This describe ship...
