Nuclear clusters in exit and entrance channels

Flow and Pressure Distributions in Short Heat Exchanger Cores with Abrupt Entrance and Exit

The typical installation of a heat exchange device usually involves a flow contraction at the core entrance and a flow expansion at the core exit. Repeated flow Contraction and expansion are experienced in the flow passages of some compact heat exchangers. The latter refers to the flow passages in the plate-fin type with louvered fins or stripped fins and in the tubular type with dimpled-circul...

Boundary induced phase transition with stochastic entrance and exit

We study an open-chain totally asymmetric exclusion process (TASEP) with stochastic gates present at the two boundaries. The gating dynamics has been modeled keeping the physical system of ion-channel gating in mind. These gates can randomly switch between an open state and a closed state. In the open state, the gates are highly permeable such that any particle arriving at the gate immediately ...

Relation between entrance and exit pupils of telescopic systems.

The incredible bouncing bullet: projectile exit through the entrance wound.

A case of a suicidal gunshot wound of the head where the projectile ricocheted within the calvarium and exited through the entrance wound is reported. Findings at the scene and from examination of the victim and the suspect weapon are presented and discussed.

Contribution of variable entrance and exit block in protected foci to arrhythmogenesis in isolated ventricular tissues.

Automatic foci with membrane potentials in the range characterized by depolarization-induced automaticity exhibit entrance block. The present study demonstrates a role of variable entrance and exit block in arrhythmogenesis. We studied canine interventricular septa with the right bundle branch exposed, isolated false tendons and isolated feline papillary muscle using standard microelectrode tec...
