Anomalous transport in a circular comb is considered. The motion takes place for fixed radius, while radii are continuously distributed along the circle. Two scenarios of anomalous transport, related to reflecting and periodic angular boundary conditions, studied. first scenario with reflection conditions diffusion corresponds conformal mapping 2D Fokker-Planck equation on comb. This topologica...

This paper describes computer modelling studies using classical Molecular Dynamics techniques and their derivative methods such as umbrella sampling and bias-exchange metadynamics to study protein behavior in various environments causing folding, unfolding and aggregation of proteins. We present applications related to two important proteins – insulin and apolipoprotein C-II (ApoC-II). Key-Word...

in order to investigate the effect of irrigation intervals and harvesting time on yield and yield components of anise (pimpinella anisum l.) a field experiment was conducted at the agricultural research station, university of zanjan in 2010. for this purpose a spilt-plot experiment based on complete randomized block design with three replications was used. three irrigation intervals (every 7, 1...

A new adaptive umbrella sampling technique for molecular dynamics simulations is described. The high efficiency of the technique renders multidimensional adaptive umbrella sampling possible and thereby enables uniform sampling of the conformational space spanned by several degrees of freedom. The efficiency is achieved by using the weighted histogram analysis method to combine the results from ...
