There is also a recovery concern: a diode's current will not decrease immediately when switching from forward-biased to reverse-biased, because discharging its stored charge takes a finite amount of time (t rr or reverse recovery time). [1] In a diode OR gate, if two or more of the inputs are high and one switches to low, recovery issues will ...
Delirium (formerly acute confusional state, an ambiguous term that is now discouraged) [1] is a specific state of acute confusion attributable to the direct physiological consequence of a medical condition, effects of a psychoactive substance, or multiple causes, which usually develops over the course of hours to days.
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
In a study involving eight patients with border zone lesions, all patients presented with transcortical mixed aphasia initially after the stroke. Three of these patients made a complete recovery within a few days post-stroke. For three other patients with more anterior lesions, their aphasia transitioned to TMoA.
In electronics, a step recovery diode (SRD, snap-off diode or charge-storage diode or memory varactor [a]) is a semiconductor junction diode with the ability to generate extremely short pulses. It has a variety of uses in microwave (MHz to GHz range) electronics as pulse generator or parametric amplifier .
Residential drug treatment co-opted the language of Alcoholics Anonymous, using the Big Book not as a spiritual guide but as a mandatory text — contradicting AA’s voluntary essence. AA’s meetings, with their folding chairs and donated coffee, were intended as a judgment-free space for addicts to talk about their problems.
Constriction of the conducting channel is accomplished using the field effect: a voltage between the gate and the source is applied to reverse bias the gate-source pn-junction, thereby widening the depletion layer of this junction (see top figure), encroaching upon the conducting channel and restricting its cross-sectional area. The depletion ...
President-elect Donald Trump has long supported House Speaker Mike Johnson — hosting him on election night, bringing him to the Army-Navy college football game last weekend and backing him ...
