The behavior of steel plate walls (SPWs) under various impulsive loadings and the effects of different mesh sizes are investigated in this paper. With the aim of accurately inspecting SPWs, a series of analyses with 250 models with different plate geometric assumptions and different blast impulsive loadings are performed to study the SPWs’ out-of-plane behavior. The mild steel material specific...

Changes in ventricular fibrillation (VF) organization occurring after the onset of global ischemia are relevant to defibrillation and survival but remain poorly understood. We hypothesized that ischemia-specific dynamic instability of the action potential (AP) causes a loss of spatiotemporal periodicity of propagation and broadening of the electrocardiogram (ECG) frequency spectrum during VF in...

Hippocampal sharp waves (SPWs) and associated fast ("ripple") oscillations (SPW-Rs) in the CA1 region are among the most synchronous physiological patterns in the mammalian brain. Using two-dimensional arrays of electrodes for recording local field potentials and unit discharges in freely moving rats, we studied the emergence of ripple oscillations (140-220 Hz) and compared their origin and cel...

In the period of digital transformation all spheres life, including educational and scientific sphere, opportunity for pedagogical workers (SPW) to present their achievements on Internet, results activities becomes important. The SPW are not only certificates various (training, internships, participation in activities), but also profiles metric databases number citations relevant publications, ...

During the second postnatal week in rats, the hippocampus exhibits a transient period of hyperexcitability. To systematically assess the relationship between the onset and end of this period and spontaneous hippocampal activity, we used silicon depth electrodes in unanaesthetized head-fixed rats from postnatal day (P)2 to P18. At all ages, hippocampal sharp waves (SPWs) were prominent in the EE...

We propose to use ultra-high intensity laser pulses with wavefront rotation (WFR) produce short, ultra-intense surface plasma waves (SPW) on grating targets for electron acceleration. Combining a smart design optimal WFR conditions identified through simple analytical modeling and particle-in-cell simulation allows decrease the SPW duration (down few optical cycles) increase its peak amplitude....

Cognitive functions go along with complex patterns of distributed activity in neuronal networks, thereby forming assemblies of selected neurons. To support memory processes, such assemblies have to be stabilized and reactivated in a highly reproducible way. The rodent hippocampus provides a well studied model system for network mechanisms underlying spatial memory formation. Assemblies of place...

Sago pith waste (SPW) has a great potential in becoming numerous kinds of reusable products as it high level starch content after went through drying process. Without proper treatment the disposal SPW could cause serious environmental problem. The process using fluidized bed dryer (FBD) was found to be more effective than other methods. Thus, this study analyzed computational fluid dynamics (CF...

Existing Web browsers handle security errors in a manner that often confuses users. In particular, when a user visits a secure site whose certificate the browser cannot verify, the browser typically allows the user to view and install the certificate and connect to the site despite the verification failure. However, few users understand the risk of man-in-the-middle attacks and the principles b...

Spike transmission probability between pyramidal cells and interneurons in the CA1 pyramidal layer was investigated in the behaving rat by the simultaneous recording of neuronal ensembles. Population synchrony was strongest during sharp wave (SPW) bursts. However, the increase was three times larger for pyramidal cells than for interneurons. The contribution of single pyramidal cells to the dis...
