PWM

Abbreviation for pokeweed mitogen.

mitogen

(mi'to-jen)
A plant-derived protein used in the laboratory to stimulate cell division (mitosis). It is frequently used in vitro to study the proliferation of lymphocytes from blood drawn during a research study. The most commonly used mitogens are phytohemagglutinin and concanavalin A. See: concanavalin A; lectin; phytohemagglutinin

pokeweed mitogen

Abbreviation: PWM
A mitogen isolated from the pokeweed plant, Phytolacca americana. In the presence of T lymphocytes, it has the capacity to induce primed B lymphocytes to proliferate and differentiate into plasma cells.

In PWM rectifiers, to convert AC input voltage to a controllable DC output voltage, width of the pulse is varied.
The presented oscillograms show that it is sufficient a time interval of only 60 ms to activate the electrovalves in full force, and that the electrovalves can be kept in an activated state with PWM pulses in ratios 1/5 in relation to the total duration.
Recently, PWM dimming has become more popular due to its flexibility, cross-platform firmware compatibility, and extensive use in advanced power saving schemes such as ambient light sensing (ALS) and content adaptive brightness control (CABC).
This type of converter changes an unregulated DC voltage into a high-frequency pulse-width modulated (PWM) voltage controlled by varying the duty cycle, then changes the PWM AC voltage to a regulated DC voltage at a high efficiency by rectification and filtering.
