1.1.1.1 Superconducting Transition and Loss of DC Resistance In the year 1908, Kamerlingh-Onnes [3], director of the Low-Temperature Laboratory at the University of Leiden, had achieved the liquefaction of helium as the last of the noble gases. At atmospheric pressure, the boiling point of helium is 4.2 K. It can be reduced further by pumping. The liquefaction of helium extended the available t...

included a review of some notable empirical evidence, analyzed and related in a wellthought out epidemiologic fashion. While the text is necessarily complex in parts, its appeal should not be limited; there is something in it to interest everyone. Perhaps a more rational and less zealous attitude concerning the use of marijuana, and its impact on us all, will accompany a widespread reading of t...

What is the relation between infrequent price adjustment and the dynamic response of the aggregate price level to monetary shocks? Caplin and Spulber (1987) provide a stark example where the answer is “none.” It is well known that by relaxing their limit assumptions some price stickiness is regained but, to our knowledge, there are no general results on this issue. In this paper we study the re...

We analyze models for the evolutionary dynamics of viral or other infectious agents within a host. We study how the invasion of a new strain affects the composition and diversity of the viral population. We show that--under strain-specific immunity--the equilibrium abundance of uninfected cells declines during viral evolution. In addition, for cytotoxic immunity the absolute force of infection,...

the aim of the present study was to investigate the relationship between the polar surface area and other molecular properties of the model drugs and their transdermal permeability across the rat skin. few model drugs which are weakly acidic (ibuprofen, aceclofenac and glipizide) and weakly basic (olanzapine, telmisartan and sildenafil citrate) were selected for the study based on polar surface...

Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...

A new generation of synchrotron radiation light sources covering the VUV, soft x-ray, and hard x-ray speclrai regions is under construction in several countries. These sources are designed specifically to use periodic magnetic undulators and low-emittance electron or positron beams to produce high-brightness near-diffraction-limited synchrotron radiation beams. Some of the novel features of the...

We study the extremality of the BEC and the BSC for Gallager’s reliability function E0 evaluated under the uniform input distribution for binary input DMCs from the aspect of channel polarization. In particular, we show that amongst all B-DMCs of a given E0(ρ) value, for a fixed ρ ≥ 0, the BEC and BSC are extremal in the evolution of E0 under the one-step polarization transformations.

In this paper, a method is proposed to determine the basic properties of γ-ray loud blazars, among them the central black hole mass, M , the Doppler factor, δ, the propagation angle of the γ-rays with respect to the symmetric axis of a twotemperature accretion disk, Φ, and the distance (i.e. the height above the accretion disk), d at which the γ-rays are created, for seven γ-ray loud blazars wi...
