Loss minimization in power system is an important research issue. Transmission line losses in a power system can be minimized by means of reactive power compensation. The continuous demand in electric power system network has caused it to be heavily loaded leading to voltage instability. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The signific...

Lee, J.C.F., J. C. Callaway, and R. C. Foehring. Effects of temperature on calcium transients and Ca -dependent afterhyperpolarizations in neocortical pyramidal neurons. J Neurophysiol 93: 2012–2020, 2005. First published November 17, 2004; doi:10.1152/ jn.01017.2004. In neocortical pyramidal neurons, the medium (mAHP) and slow AHP (sAHP) have different relationships with intracellular [Ca ]. T...

The concentration-dependent actions of neostigmine, a carbamate anticholinesterase agent, were studied on the acetylcholine receptor channel complex in voltage-clamped twitch fibers of costocutaneous muscles of garter snakes. Low concentrations of neostigmine (10(-6) or 10(-5) M) increased miniature endplate current (MEPC) amplitude and the time constant of MEPC decay without changing the relat...

OBJECTIVE To determine whether actions on nicotine acetylcholine receptors (nAChRs) contribute to ethanol's depressant effects on the autonomic nervous system. METHODS The acute effects of ethanol on nAChRs were examined in primary cultured superior cervical ganglion (SCGs) by whole-cell patch clamp recordings. After the whole-cell configuration was formed, drugs diluted to various concentrat...

KOTO is the first experiment in the world specialized in observing the decay KL → π0νν . The decay is sensitive to new physics scenarios beyond the Standard Model. The most important detector of KOTO is the CsI calorimeter, which measures positions and energies of gammas from KL, in order to reconstruct the vertexes of them. There are mainly three requirements for the calorimeter. First, dynami...

We report a scanning photocurrent microscopy (SPCM) study of colloidal lead selenide (PbSe) quantum dot (QD) thin film field-effect transistors (FETs). PbSe QDs are chemically treated with sodium sulfide (Na2S) and coated with amorphous alumina (a-Al2O3) by atomic layer deposition (ALD) to obtain high mobility, air-stable FETs with a strongly gate-dependent conductivity. SPCM reveals a long pho...

Adaptation to different levels of illumination is central to the function of the retina. Here, we demonstrate that levels of the miR-183/96/182 cluster, miR-204, and miR-211 are regulated by different light levels in the mouse retina. Concentrations of these microRNAs were downregulated during dark adaptation and upregulated in light-adapted retinas, with rapid decay and increased transcription...

Electron tunneling through self-assembled monolayers (SAMs) of alkanethiols was investigated using nanometer scale devices that allow temperature-dependent current-voltage, I(V, T), measurements. The I(V, T) measurement results show, for the first time, temperature-independent electron transport characteristics, proving direct tunneling as the transport mechanism in alkanethiol SAMs. The measur...

Characteristic times of perovskite solar cells (PSCs) have been measured by different techniques: transient photovoltage decay, transient photoluminescence, and impedance spectroscopy. A slow dynamic process is detected that shows characteristic times in the seconds to milliseconds scale, with good quantitative agreement between transient photovoltage decay and impedance spectroscopy. Here, we ...

An electrostatic force microscope was used to write and image localized dots of charge in a double barrier CeO2 /Si/CeO2 /Si~111! structure. By applying a relatively large tip voltage and reducing the tip to sample separation to 3–5 nm, charge dots 60–200 nm full width at half maximum of both positive and negative charge have been written. The total stored charge is found to be Q 56(20– 200)e p...
