A legendary Finnish skater and a more recentconvert to surfing and surf photography, Arto Saari exhibits a keen eye with powerful surf photography. Photographers for the Washington Post capturedscenes from Election Dayall over the country.
After reduction via azoreductases in gut microbiota, prontosil was metabolized to sulfanilamide, which exhibits potent antibacterial activities. In addition, it was noted in rats that the conversion of prontosil to sulfanilamide can be suppressed by antibiotics, leading to the reduced antibacterial ...
In Fig. 7.39(d) the turn-on and turn-off transitions have been performed under soft switching and zero current switching (ZCS@turn-off), respectively, where the ZCS exhibits zero power losses. Finally, in Fig. 7.39(e) the turn-on and turn-off transitions have been performed with ZVS ...
A DC current sensor based on an optically pumped atomic magnetometer is proposed.It has a high linearity in a wide operation range,since the magnetometer measures the absolute magnitude of the magnetic field produced by the current to be measured.The current sensor exhibits a high accuracy with ...
A voltage regulator exhibits a load line that is piecewise linear. This piecewise linearity variation has a first constant voltage segment Vat which output voltage is regulated for output currents less than or equal to the leakage current I. The output voltage Vcorresponds to the maximum output vo...
Current Noise from the Sensor (in_source)The sensor itself contributes current noise, and we have to live with it. It can have any shape over frequency. For example: a photodiode exhibits shot noise, Isn, from photocurrent, IP, and dark current, ID, as well as Johnson noise, Ijn, ...
Buck-boost direct current (DC)/DC converters are commonly applied as RES MPPT converters. However, the basic buck-boost converters suffer from discontinuous input current [12,13] resulting in discontinuous RES current, thus deteriorating the MPPT process. To overcome the latter, a large electrolytic...
Current mode control is preferred in grid connection as it exhibits better transient response and results in improved power factor with simple control circuit [5]. The current control techniques can be linear or nonlinear; however, the nonlinear controllers based on natural reference frame outperforms...
Moreover, JH is more potent in modulating viral life cycle, whereas LH exhibits better efficacy in regulating host anti-viral responses, suggesting LH and JH could be potentially an alternative therapy for emerging viral diseases. They also found that both LH and JH are potentially being able ...
VLC exhibits a great feature of illumination and communication at the same time. The visible light spectrum has a large bandwidth which can be an additional solution for radio frequency (RF) communication. The visible light spectrum ranges from 380 nm to 750 nm, corresponding to a frequency ...
