It is known that the satisfiability problem (SAT) can be efficiently solved by a uniform family of P systems with active membranes with two polarizations working in a maximally parallel way. We study P systems with active membranes without non-elementary membrane division, working in minimally parallel way. The main question we address is what number of polarizations is sufficient for an effici...

The Hebbian hypothesis of activity-dependent synaptic plasticity has gained much support from experimental studies of long-term potentiation and depression. Such studies have also uncovered complex patterns of competition among the synapses. Such eeects may be due to the neuron redistributing its limited synaptic resources as synaptic strengths change. In computational models this strategy is c...

Modern dating platforms have given rise to new dating and sexual behaviors. In the current study, we examine predictors of sending unsolicited explicit images, a particularly underexplored online sexual behavior. The aim of the current study was to explore the utility of dark personality traits (i.e., narcissism, Machiavellianism, psychopathy, and sadism) and self-rated mate value in predicting...

The cell membrane provides a physical barrier that separates the internal contents of a cell from the surrounding environment. This separation enables the generation of higher (or lower) concentrations of chemicals within the cell compared to the extracellular conditions. Furthermore, it enables the formation of electrochemical gradients across the cell membrane that can be used to drive biolog...

This paper addresses some general questions of quantum information theory arising from the transmission of quantum entanglement through (possibly noisy) quantum channels. A pure entangled state is prepared of a pair of systems R and Q, after which Q is subjected to a dynamical evolution given by the superoperator $. Two interesting quantities can be defined for this process: the entanglement fi...

practiced in various journals, peer reviewing is undoubtedly the core of science (as opposed to non-science ) production in all disciplines, particularly in medical sciences due to their direct and immediate effect on human health. publication provides the chance for bits of knowledge to get integrated into the body of global knowledge and to share it with other researchers ( 1 ). this involves...

Performance   evaluation in regular periods is one of the ways in which organizations can   evaluate their performance as well as weak and strong points unifiedly and   precisely. These days, mathematical models are also used to evaluate the   efficiency and productivity of various units. These units are a collection of   education, research and service activities as input and output factors an...
