FRET (Förster Resonance Energy Transfer)-based protein voltage sensors can be useful for monitoring neuronal activity in vivo because the ratio of signals between the donor and acceptor pair reduces common sources of noise such as heart beat artifacts. We improved the performance of FRET based genetically encoded Fluorescent Protein (FP) voltage sensors by optimizing the location of donor and a...

in this research, the decay resistance of bagasse-polypropylene composite has been evaluated. the scope of research was to assess the effect of different weight percentages of bagasse (40, 55 and 70%) and coupling agent, (mapp) maleic anhydride grafted polypropylene (0, 4 and 6%) on the fungal decay of the composite. astm d1413-99 modified test method was used to carry out the decay test, trame...

We have studied photo-induced effects in a p-type transistor based on a [1]benzothieno[3,2-b]benzothiophene (BTBT) derivative. Repetition of blue light irradiation and electrical characterization under dark reveals that its threshold voltage gradually shifts in the positive direction as the cumulative exposure time increases. This shift is slowly reversed when the transistor is stored under dar...

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.

Whole-cell and cell-attached patch-clamp recordings were used to investigate the nature of GABAA receptor-mediated inhibition in the adult rat dentate gyrus in standard 400-microns-thick horizontal slices. In the presence of the glutamate receptor antagonists D-2-amino-5-phosphonovaleric acid and 6-cyano-7-nitroquinoxaline-2,3-dione, whole-cell voltage-clamp experiments with chloride-filled ele...

Excitatory synaptic transmission was investigated in interneurons of the parvocellular nucleus tractus solitarius (pNTS) by performing patch-clamp experiments in thin slice preparations from rat brain stem. Stimulation of single afferent fibers evoked excitatory postsynaptic currents (EPSCs) mediated by glutamate receptors of the DL-alpha-amino-3-hydroxy-5-methylisoxazole-propionic acid (AMPA) ...

Ion back-bombardment is the dominant mechanism that limits the operating lifetime of DC high voltage GaAs photoelectron guns. In this work, an electrically isolated anode electrode was used to distinguish the QE damage contributions of ions produced within the cathode/anode gap and those produced downstream of the anode. This new anode design provides a means to suppress QE decay due to ionized...

We report measurements of the holographic diffraction efficiency (HDE) of single photorefractive gratings fixed by an externally applied voltage pulse in Sra., Bao..#h206. The polarization grating HDE and decay rate are strongly dependent on the grating spacing and also depend on the intensity of the light beams during the recording and erasing/reconstruction process. Knowledge of the dependenc...

The transverse acceptance of the ATF damping ring, estimated from the beam current decay and the timedependent vacuum pressure, is smaller than the design value. We have measured its dependence on sextupole settings, linear coupling, global orbit distortions, local orbit bumps, rf frequency, rf voltage, and on the working point in the tune diagram. We describe the procedure applied to infer the...
