This paper designs and evaluates a practical algorithm, called Prac-ReProCS, for recovering a time sequence of sparse vectors St and a time sequence of dense vectors Lt from their sum, Mt := St + Lt, when any subsequence of the Lt’s lies in a slowly changing low-dimensional subspace. A key application where this problem occurs is in video layering where the goal is to separate a video sequence ...

Object recognition is central to perception and cognition. Yet relatively little is known about the environmental factors that cause invariant object recognition to emerge in the newborn brain. Is this ability a hardwired property of vision? Or does the development of invariant object recognition require experience with a particular kind of visual environment? Here, we used a high-throughput co...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

We study the exponential stability in H 2 norm of nonlinear Saint-Venant (or shallow water) equations with arbitrary friction and slope using a single proportional-integral (PI) control at one end channel. Using good but simple Lyapunov function we find explicit condition on gain PI to ensure any steady-states. This is independent slope, coefficient, length river, inflow disturbance and, more s...
