For the circuit in Figure, VBE3=VBE4=0.7V, the current Io is ( ) A、0.5 mA B、1mA C、0.86mA D、2mA
Here, we describe the expression and functional regulation of aromatase in a major type of hippocampal IN in mice. We found that CA1 PV-INs contribute to estradiol synthesis within the brain. In turn, brain aromatase influences CA1 synaptic inhibition through regulation of PNNs surrounding PV-IN...
To get more deep insights into the activity, the electrochemical impedance spectroscopy (EIS) was employed to evaluate the charge transfer resistance (Rct) of the prepared materials with the equivalent circuit model, as shown in Figs. 6f and S9. Evidently, the NiMoSe/NF-1 and NiMoSe/NF-2 ...
The field of cellular microbiology, rooted in the co-evolution of microbes and their hosts, studies intracellular pathogens and their manipulation of host cell machinery. In this review, we highlight emerging technologies and infection models that recent
In UK, Closed Circuit Televisioncameras are everywhere. They help the police solve crimes and keep the streets safe. But that’s not all they do. They also catch people doing very stupid or smart things.One of the videos is of a British woman Mary Bale.
The existence of alternative promoters for a single gene is one explanation that could account for multiple TSS, as exemplified bypstS,which encodes a phosphate-binding periplasmic protein, and was previously shown to have two TSS located downstream from two PhoB binding motifs (B1 and B2) corres...

system’s output relative to the input (frequency response). The plot is based on poles and zeros of the circuit’s transfer function. Testing of actual circuits, shows that the real gain and phase traces are not perfect straight lines, especially near the theoretical pole and zero frequencies...
Regarding the choice of the numerical approach, an analytical solution based on the simple series C-R-C circuit shown in Fig.1d should provide a useful first estimate of the E-Field in most cases. This approach can be extended to non-sinusoidal waveforms by estimating the frequency associated...
channel subfamily Q member 1 (KCNQ1), KCNE3 increases and KCNE4 decreases the slow component of the delayed rectifier current, IKs. The functional equivalent of these expression changes is a specific pattern of repolarization heterogeneity in the VT circuit that creates the substrate for reentrant...
