Q: Consider an uncorrelated (white) Gaussian signal s(t). Calculate its 3rd and 4th order moments, m3 = ⟨s(t1)s(t2)s(t3)⟩ and m4 = ⟨s(t1)s(t2)s(t3)s(t4)⟩. Confirm with simulation. The third moment m3 = ⟨s(t1)s(t2)s(t3)⟩ is zero. Namely, if t1 ̸= t2 ̸= t3 then m3 = ⟨s⟩ = 03 = 0. If t1 = t2 = t3, m3 = ⟨ s3 ⟩ = ́ N (0, σ2)x3dx = 0, as this is the integral over an odd function. For t1 = t2 ̸= t3, m3 = ...

Hyperpolarizability ratios for molecules have been measured with 0.1% accuracy, at I = 5 14.5 nm, in the gas phase as a function ofdensity. These measurements yieldy(Hz)/y(He)= 19.55kO.03, y(Ar)/y(Hz)=1.668f0.002 and y(N~)/y(Hz)= 1.283+0.001 in the zero density limit. Pair interaction contributions, determined from the density dependence of y, are larger than predicted assuming classical multip...

In quantum zero knowledge, the assumption was made that the verifier is only using unitary operations. Under this assumption, many nice properties have been shown about quantum zero knowledge, including the fact that Honest-Verifier Quantum Statistical Zero Knowledge (HVQSZK) is equal to Cheating-Verifier Quantum Statistical Zero Knowledge (QSZK) (see [Wat02, Wat06]). In this paper, we study wh...

Details are presented of recent improvements to hardware and analysis code components of the DIII-D density profile reflectometer system. The improvements to the hardware increased the system signal-to-noise ratio and reduced spurious reflections. An improved automated method is developed to accurately determine the zero density plasma start position. With these improvements the uncertainty in ...

In this article, perfectly matched layer (PML) for the boundary treatment and an efficient compact two dimensional finite-difference frequency-domain (2-D FDFD) method were combined to model photonic crystal fibers (PCF). For photonic crystal fibers, if we assume that the propagation constant along the propagation direction is fixed, three-dimensional hybrid guided modes can be calculated by us...

This research was designed to study the effect of bitter almond oil on the healing of open skin wounds in rats. Thirty female adult rats were randomly divided into experimental (n=15) and control (n=15) groups. Under general anesthesia and sterile conditions, one quadrangular (surface area=22 mm) full thickness skin wound was made on the dorsum of each rat. The day of surgery was considered as ...

We study a system containing many particles of identical kinematics with a zero range interaction that scatters one from the other, and with the possible exchange of an attribute. Taking an initial condition in which the attribute is asymmetrically distributed in the regions of momentum space occupied by the particles, we study the rate at which it becomes uniformly distributed, through collisi...

Article history: Received on: 11/01/2016 Revised on: 09/02/2016 Accepted on: 04/03/2016 Available online: 30/03/2016 An accurate and precise UPLC method was developed for the simultaneous estimation of efavirenz and lamivudine in pharmaceutical dosage forms. The chromatographic analysis was performed on Acquity UPLC BEH Shield RP18 (50 × 3 mm, 1.7 μm) column with mobile phase consisting of 10% ...

We assessed the effect of the vasodilating calcium channel blocker nitrendipine on glucose tolerance in young spontaneously hypertensive rats (SHR) (n = 15). The nitrendipine group received 1 g/kg chow for 3 weeks. Untreated SHR (n = 14) served as controls. At 3 weeks body weight was comparable, whereas systolic blood pressure was 157 +/- 9 mm Hg in nitrendipine-treated rats versus 191 +/- 10 m...
