The dynamic response of polar nanoregions under an AC electric field was investigated by measuring the frequency dependence of the quadratic electro-optic (QEO) effect in a paraelectric KTa0.61Nb0.39O3 single crystal near the para-ferroelectric phase boundary (0 °C < T-Tc < 13 °C). The QEO coefficient R11 - R12 reached values as large as 5.96 × 10(-15) m(2)/V(2) at low frequency (500 Hz) and gr...

Let rk(n) denote the number of representations of an integer n as a sum of k squares. We prove that for odd primes p, r11(p) = 330 31 (p + 1) − 22(−1)(p−1)/2p4 + 352 31 H(p), where H(p) is the coefficient of q in the expansion of

During the lunar month of Ramadan, Muslims abstain from eating, drinking and smoking from sunrise to sunset. We reported previously that Ramadan provokes a shortening in nocturnal total sleep time by 40 min, an increase in sleep latency, and a decrease in slow-wave sleep (SWS) and rapid eye movement (REM) sleep duration during Ramadan. During the same study, the effects of Ramadan intermittent ...

A single-cell secretion assay was used to detect cells that secrete products which react with an antiserum that binds T cell antigen-binding polypeptides. The antiserum (R11), which was produced by immunization of rabbits with a murine trinitrophenyl-specific suppressor factor, reacts with T cells and their products and with a suppressor T-cell clone but not with B cells or their products. The ...

Many thermal resources are not reasonably used in the chemical industry’s production process. To recover waste heat from organic residue-calcium carbonate (CaCO3), which is added to inhibit hydrogen production, an Rankine cycle (ORC) system applied this research. An ORC can reuse low-temperature that fully utilized. In study, mathematical model of biomass power generation constructed. Five work...

We derive p+1-dimensional (p=1,2) maximally supersymmetric U(N) Yang-Mills theory from the wrapped supermembrane on R11−p × T p in the light-cone gauge by using the matrix regularization. The elements of the matrices in the super Yang-Mills theory are given by the Fourier coefficients in the supermembrane theory. Although our approach never refers to both D-branes and superstring dualities, we ...
