Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

Power Factor revisited

2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020
Power factor has been used for over a century as a rule of thumb to estimate the cost of the losses incurred in delivering reactive power. But it has been extremely troublesome to apply to three-phase systems. The same load might be penalized by some instruments, and not by others. There have been two noteworthy efforts at solution. In 1919 a committee

Power Factor Correction

Practical Power Plant Engineering, 2020
Power Factor Correction and Voltage Optimisation have been around since the turn of the 20 century and although in many cases their individual benefits and attributes make them a viable form of energy reduction in the right environment, in truth it is ...

LED Power Factor and Quality Factor

2019 IEEE Industry Applications Society Annual Meeting, 2019
This paper presents the LED power factor and quality factor simply characterized from the available terminal average current, average voltage, and RMS current to evaluate the electric power quality of LEDs. The LED average power is composed of the bandgap power and the resistive power due to the forward voltage and equivalent series resistor in the LED
