We investigate the asymptotic mesoscopic behavior of a spatially extended stochastic neural networks dynamics in random environment with highly random connectivity weights. These systems model the spatiotemporal activity of the brain, thus feature (i) communication delays depending on the distance between cells and (ii) heterogeneous synapses: connectivity coefficients are random variables whos...

In studies of the temporal flexibility of the stereoscopic system, it has been suggested that two different processes of binocular depth perception could be responsible for the flexibility: tolerance for interocular delays and temporal integration of correlation. None has investigated the relationship between tolerance for delays and temporal integration mechanisms and none has revealed which m...

A novel stochastic system model with multiple Markovian processes for networked control system (NCS) is developed as a two chains Markovian jump linear system. By using an active sampling method, random time delays are reshaped into short time delays which are less than one sampling period such that the structure of the augmented discrete-time model becomes straightforward. Based on Lyapunov ap...

Four experiments are presented that explore situations in which a decision maker has to rely on personal experience in an attempt to minimize delays. Experiment 1 shows that risk-attitude in these timesaving decisions is similar to risk-attitude in money-related decisions from experience: A risky prospect is more attractive than a safer prospect with the same expected value only when it leads t...

We consider networks of coupled maps where the connections between units involve time delays. We show that, similar to the undelayed case, the synchronization of the network depends on the connection topology, characterized by the spectrum of the graph Laplacian. Consequently, scale-free and random networks are capable of synchronizing despite the delayed flow of information, whereas regular ne...

We consider problems of inventory and admission control for make-to-stock production systems with perishable inventory and impatient customers. Customers may balk upon arrival (refuse to place orders) and renege while waiting (withdraw delayed orders) during stockouts. Item lifetimes and customer patience times are random variables with general distributions. Processing, setup, and customer int...

The Internet connects millions of computers worldwide, and provides a new potential working environment for remote-controlled telerobotic systems. The main limitation of using the Internet in this application is random delays between communicating nodes, which can cause disturbances in human–machine interaction and affect telepresence experiences. This is particularly important in systems integ...

BACKGROUND AND PURPOSE Emergency department (ED) crowding occurs when demands for ED care exceed the supply of available resources. Prior studies have shown that ED crowding is associated with a delay in provision of critical ED services, but the impact of ED crowding on acute stroke care has not been extensively studied. METHODS We conducted a retrospective study of patients who presented to...

in this paper, the problem of decentralized model reference adaptive control (mrac) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. to compensate the effect of input delay indirectly, a smith predictor built on. to handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic f...

Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
