We use computer simulations to study the glass transition of dense fluids made of polydisperse repulsive spheres. For hard particles, we vary the volume fraction, phi , and use compressible particles to explore finite temperatures, T>0 . In the hard sphere limit, our dynamic data show evidence of an avoided mode-coupling singularity near phi(MCT) is approximately 0.592; they are consistent with...

In order to determine if human LAK cells were cytotoxic against autologous AM phi, we studied the ability of human peripheral blood MNCs, stimulated in vitro with recombinant human IL-2, to lyse AM phi in a four-hour 51Cr-release assay. These cells showed significant cytotoxicity against autologous AM phi. The AM phi which had been cultured for four days served as better targets than freshly is...

The locus of all points in the complex plane of the dielectric function ?[?(r) + j?(i) = |?| exp(jtheta)], that represent all possible interfaces characterized by the same pseudo-Brewster angle theta(p)B of minimum p reflectance, is derived in the polar form: |?| = l cos(zeta/3), where l = 2(tan(2)Phi(p)B)k, zeta = arccos(- costheta cos(2)Phi(p)B/k(3)), and k = (1 - 2/3 sin(2)Phi(p)B)(1/2). Fam...

There are errors in Equation (3). In the description of Equation (3), the equilibrium frequencies PIX are incorrectly defined in terms of pi, where in fact they should be defined in terms of phi. Please see the corrected description of Equation (3) here.

The Stepanov equation, relating the intensity of emission, f(e)(v), at a given frequency, and that of absorption, k(v), at the same frequency, is applied, in its modified form (see equation 3 in text) to suspensions of Chlorella, Porphyridium, and Anacystis and to chlorophyll solutions. This application can reveal whether the yield of fluorescence, Phi(v), is constant, or changes with frequency...

We study traveling fronts of equations of the form u(tt)+phi(u)u(x)=u(xx)+f(u). A criterion for the transition from linear to nonlinear marginal stability is established for positive functions phi(u) and for any reaction term f(u) for which the usual parabolic reaction diffusion equation u(t)=u(xx)+f(u) admits a front. As an application, we treat reaction diffusion systems with transport memory.

Five bacteriophages infecting only Saccharopolyspora erythraea (formerly Streptomyces erythreus) among 43 Streptomyces spp. tested were classified into two groups by phage-host relationships, restriction enzyme mapping, cohesive-end determinations, and Southern hybridizations. phi SE6, the most frequently isolated phage, produced clear plaques on all hosts tested, while phi SE45, phi SE57, phi ...

We derive exact general solutions (as opposed to attractor particular solutions) and corresponding first integrals for the evolution of a scalar field $\phi$ in universe dominated by background fluid with equation state parameter $w_B$. In addition previously-examined linear [$V(\phi) = V_0 \phi$] quadratic \phi^2$] potentials, we show that exist power law potential $V(\phi) \phi^n$ $n 4(1+w_B)...

In this article, we analyze the oscillation behavior of half-linear differential equation $$\big( r(t) t^{p-1} \Phi(x')\big)' + \frac{s(t)}{t \log^pt} \Phi(x) = 0, \quad \Phi(x)=|x|^{p-1}\text{sgn} x, p > 1. $$ Applying modified Prufer angle and a general averaging technique over unbounded intervals, prove an criterion for studied equation. We point out that presented is new even in linear c...
