We measured the low frequency (10mHz < f < 10Hz) resistance fluctuations (Noise) in single crystalline ferromagnetic Ni nanowires (diameter ∼ 35nm) in the temperature range 80K-300K. The noise spectral power shows 1/f dependence. The nanowires in an applied magnetic field show negative magetoresistance that saturates for H ≤ HC . The noise spectral power shows a reduction in low applied field a...

Considering the current severe atmospheric pollution problems in China, a comprehensive understanding of distribution and spatial variability PM2.5 is critically important for controlling improving future environment. This study first explored concentrations then developed methodology “dependence analysis” to investigate relationship different cities China. The data daily were collected from en...

The pseudo-SU(3) model is extended to explicitly include the spin and protonneutron degrees of freedom. A general formalism for evaluating matrix elements of one-body and two-body tensor operators within this framework is presented. The pairing interaction, which couples different irreducible representations of SU(3), is expressed in terms of pseudo-space tensors and a general result is given f...

We consider the dephasing of two internal states |0〉 and |1〉 of a trapped impurity atom, a so-called atomic quantum dot (AQD), where only state |1〉 couples to a Bose-Einstein condensate (BEC). A direct relation between the dephasing of the internal states of the AQD and the temporal phase fluctuations of the BEC is established. Based on this relation we suggest a scheme to probe BEC phase fluct...

background: infertility is a major reproductive health in gynecology. according to the world health organization, there are currently 50-80 million infertile couples in the world. objective: considering the critical effects of lifestyle on reproductive health, this study aimed to compare the lifestyle of fertile and infertile couples in kermanshah during 2013. materials and methods: this resear...

The work presented as part of this dissertation is primarily motivated by a randomized trial for HIV serodiscordant couples. Specifically, the Multisite HIV/STD Prevention Trial for African American Couples is a behavioral modification trial for African American, heterosexual, HIV discordant couples. In this trial, investigators developed and evaluated a couple-based behavioral intervention for...

In preparation for a demonstration of optical stochastic cooling in Cornell Electron Storage Ring, we have developed particle tracking simulation to study the relevant beam dynamics. Optical radiation emitted pickup undulator gives momentum kick that same kicker undulator. The optics electron bypass from couples betatron amplitude and offset path length so reduces emittance spread. Nearby elect...

The composition dependence of ferrite growth kinetics in Fe-C-X ternary alloyed steels, where X = Ni, Mn, Mo, Cr, Si, was investigated using a high-throughput approach. Compositionally graded samples were subjected to situ time- and space-resolved X-ray diffraction during intercritical annealing. To this end, diffusion couples created between binary Fe-C different alloys, hot uniaxial compressi...

abstract background: the world health organization announced the acceptable level of cesarean section (cs) as 10-15%. in recent years, the rate of cs has been increasing irregularly. lack of appropriate knowledge and attitude among couples plays a major role in this regard. this study tried to compare the effects of a childbirth training workshop on knowledge, attitude, and delivery method. mat...

The concept of dependency in a bivariate and in a multivariate setting has been largely studied in recent literature and the development of the theory of copulas has determined a great impact in the study of measures of dependence. This is of interest in economics, insurance, in finance and risk management and in many areas of applied probability and statistics. Several notions of positive depe...
