this article is a report of calculation and measurements of a p+-n insb photo-diode leakage current fabricated by mesa on the basis of the calculation and measurement of different leakage currents in insb photo-diode along with its variation it shows that at relatively low reverse biases (up to about 300 mv) g-r and shunt current are dominant. but at high reverse biases the tunneling current do...

DNA concentration has been recently suggested to be the reason why different arrangements are revealed for K(+)-stabilized human telomere quadruplexes by experimental methods requiring DNA concentrations differing by orders of magnitude. As Raman spectroscopy can be applied to DNA samples ranging from those accessible by absorption and CD spectroscopies up to extremely concentrated solutions, g...

It is known that the guanine-rich strands in proto-oncogene promoters can fold into G-quadruplex structures to regulate gene expression. An intramolecular parallel G-quadruplex has been identified in MET promoter. It acts as a repressor in regulating MET expression. However, the full guanine-rich region in MET promoter forms a hybrid parallel/antiparallel G-quadruplex structure under physiologi...

Metamaterial resonances have demonstrated outstanding abilities to control electromagnetic waves, which brings promises directly use them create unique channels for wave tunneling through barriers. Herein, an effect is realized by antiparallel dipole resonance in a multilayer metamaterial composed of pair metallic unsplit ring resonators (USRRs) with split resonator (SRR) sandwiched between the...

Nanosecond scale molecular dynamics simulations have been performed on antiparallel Greek key type d(G7) quadruplex structures with different coordinated ions, namely Na+ and K+ ion, water and Na+ counter ions, using the AMBER force field and Particle Mesh Ewald technique for electrostatic interactions. Antiparallel structures are stable during the simulation, with root mean square deviation va...

Due to the high sensitivity, nearly linear response, and easy availability, we will use a 1N4148 diode for the temperature transducer in our measurements. The current conducted through an ideal diode is described by the Shockley ideal diode equation: I D = I S exp q V D n k B T − 1 where q is the electron charge, k B is Boltzmann's constant, T is the temperature of the diode junction, and V D i...

Background: Numerous lasers are currently available for hair removal. Objective: To study the efficacy of a pulsed diode laser for removing unwanted hair. Patients and Methods: In this quasi-experimental clinical trial, 39 patients with unwanted hairs on chin referred to Novin-Didegan Laser Center in Tehran were treated with a diode laser system (Palomar, 810nm). Fluences ranging from 40 to 64 ...
