aThe analysis of the inverter design for different voltages (12, 24, and 48 V) and frequencies (400, 800, and 1600 Hz) at a power output of 对变换器设计的分析为不同的电压 (12, 24和48个V) 和频率 (400, 800和1600赫兹) 在功率输出[translate]...
Objective To observe the effects of electroacupuncture (EA) of three different frequencies (2 Hz, 80 Hz and 2 Hz/80 Hz) on the free radicals in hippocampus of vascular dementia (VD) model mice. Methods A total of 100 Kunming mice were randomly divided into a sham operation group, a ...
Frequency parameters seems to be not such a strong reliable indicator of emotions as they may both increase and decrease with an increase in arousal30, e.g. a shift in energy distribution towards higher frequencies was found in Weddel seal36, silver fox37, house cats38, red-fronted lemur39,...
In vitro studies have shown that a neuron’s electroresponsive properties can predispose it to oscillate at specific frequencies. In contrast, network activity in vivo can entrain neurons to rhythms that their biophysical properties do not predispose the
A band-pass filter (0.01–3 Hz) was applied to remove slow drifts, and high frequencies contribution. Then, with the hmrR_StimRejection function, we assessed the absence of trials containing residual motion artifacts before the calculation of the hemodynamic response function (HRF). An age-...
As the frequency of an applied AC voltage increases, the inductive reactance of the ESL increases to a point at which it is equal to the capacitive reactance of the device, and the capacitor behaves as a resistor. At frequencies above this point, the capacitor is effectively an inductor. ...
Table 1 presents the frequencies of analysis units per type of description focus and content. Regarding the description focus, teacher information/elaboration occurred the most frequently among the three stress groups. Thus, the teachers shared their beliefs, strategies, goals and feelings related to ...
aFine 基音 error tests of the instantaneous 基音 estimation algorithm were performed for 4,000 different synthetic signals, with frequencies ranging from 50 Hz to 4000 Hz, including both clean signals and signals contaminated with noise 瞬间基音估计算法的美好的基音错误试飞为4,000个不同综合性信号将...
and relative power of its main oscillatory activity and the exponent and offset of the aperiodic component of its power spectrum (Fig.3b). The frequencies of the oscillations were relatively narrow, ranging between 5 and 10 Hz (frequency peak: 7.9 ± 1.04 Hz and 8.1 ± 1.4...
