in this paper, surface roughness of ht29 cancerous is determined using topography images obtained by atimic force microscopy (afm). the mean radiuses of cell and substrate surface asperities are determined, based on results of conducted roughness analysis and rabinovich roughness theory. these values have been applied in the equations of rough particle nanomanipulation dynamic model and the amo...

Recent progress in the theory of the Newcomb equation is reported. Emphasis is put on the analysis of external modes including peeling modes (high n kink modes), where n is the toroidal mode number. A theory for low n external modes is developed so that it is also useful for the analysis of resistive wall modes.

The viscous drag on a slender rod by wall is important to many biological and industrial systems. This critically depends the separation between can be approximated asymptotically in specific regimes, namely far from, or very close to, wall, but typically determined numerically for general separations. In this note we determine an asymptotic representation of local parallel which valid all poss...

We use mean-field theory methods from Statistical Mechanics to derive the "softmax" nonlinearity from the discontinuous winnertake-all (WTA) mapping. We give two simple ways of implementing "soft max" as a multiterminal network element. One of these has a number of important network-theoretic properties. It is a reciprocal, passive, incrementally passive, nonlinear, resistive multiterminal elem...

Polychloro-para-xylylene (parylene-C) is a flexible and transparent polymer material which has excellent chemical stability and high biocompatibility. Here we demonstrate a polymer device based on single-component parylene-C with memory and temperature sensing functionalities. The device shows stable bipolar resistive switching behavior, remarkable storage window (>104), and low operation volta...

recent studies show significant reduction of postural stability in transtibial amputees (ttas) especially when a perturbation is applied. however, no record has been seen on the consequences of such perturbation on the stump-socket interface pressure (ssip). our objective was to investigate whether such perturbation impose excessive pressures on the stump. we were also interested on the type of...

Nanoscale resistive switching devices (memristive devices or memristors) have been studied for a number of applications ranging from non-volatile memory, logic to neuromorphic systems. However a major challenge is to address the potentially large variations in space and time in these nanoscale devices. Here we show that in metal-filament based memristive devices the switching can be fully stoch...
