The spin glass behavior near zero temperature is a complicated matter. To get an easier access to the spin glass order parameter Q(x) and, at the same time, keep track of Qab, its matrix aspect, and hence of the Hessian controlling stability, we investigate an expansion of the free energy functional around its “spherical” approximation. This expansion is obtained by introducing a constraint fie...

This paper provides a summary analysis of the typological and historical development of active glass walls. From the beginning of the glass revolution, the fascination with large areas of transparency has been tempered by the negative environmental effects they can produce: excessive heat loss when it is cold, excessive heat gain when the sun shines, and even excessive daylighting. Comments Pre...

The Gilroy-Phillips model of relaxational jumps in asymmetric double well potentials, developed for the Arrhenius-type secondary relaxations of the glass phase, is extended to a formal description of the breakdown of the shear modulus at the glass transition, the α-process. The extension requires the introduction of two separate parts of the barrier distribution function f(V ), with a different...

Deformation of glass using heat occurs in many industrial and artistic applications, including the manufacturing of laboratory glass products, drawing of fiber optics, and hand-blown artistic creations. The formation of glass objects is an art, but the trialand-error procedures can be reduced by development of a systematic theory, especially when the objects are formed using mechanical means. G...

according to iran’s folk medicine, camphor, a crystalline ketone obtained from essential oils of cinnamomum camphora, has both sexual behavior attenuating and enhancing properties. this study examined the effects of camphor on sexual behavior in male rats. twenty four sexually mature male sprague-dawley rats were randomly divided into 4 groups receiving daily i.p. injections of olive oil as veh...

Soft vibrational modes have been used to explain anomalous thermal properties of glasses above 1 K. The soft-potential model consists of a collection of double-well potentials that are distorted by a linear term representing local stress in the liquid. Double-well modes contribute to the configurational entropy of the system. Based on the Adam-Gibbs theory of entropically driven relaxation in l...

We present a novel approach for fabricating monodisperse phospholipid vesicles with high encapsulation efficiency using controlled double emulsions as templates. Glass-capillary microfluidics is used to generate monodisperse double emulsion templates. We show that the high uniformity in size and shape of the templates are maintained in the final phospholipid vesicles after a solvent removal ste...

The heat capacity of a supercooled liquid subjected to a temperature cycle through its glass transition is studied within a kinetic model. In this model, the beta process is assumed to be thermally activated and described by a two-level system. The alpha process is described as a beta relaxation mediated cooperative transition in a double well. The overshoot of the heat capacity during the heat...

1. E. M., a girl of 5 years, was admitted to the hospital in November, 1938, because of double incontinence since birth. Examination revealed atrophy of the buttocks, a peculiar waddling gait, rectal sphincter not demonstrable, almost continuous urinary dribbling, absence of the lower sacrum and coccyx. Spinal lipiodol was unsuccessful because of subdural injection. Operation: Lumbo-sacral lami...
