With a lot of attention focused on the potential for national health care reform and the raucous town hall meetings held by various members of Congress, it is important to remember that there are three substantive changes to the Federal Ethics in Physician Self-Referrals Act (known as the “Stark Law”) scheduled to take effect on October 1, 2009. Physicians and hospitals should review their join...

We explore the consequences of introducing a complex conductivity into the quantum Hall effect. This leads naturally to an action of the modular group on the upper-half complex conductivity plane. Assuming that the action of a certain subgroup, compatible with the law of corresponding states, commutes with the renormalisation group flow, we derive many properties of both the integer and fractio...

The permanent strengths of interstitial-free (IF) steels with different grain sizes and dislocation densities processed by severe plastic deformation (SPD) subsequent annealing are systematically investigated. Permanent strength, which is athermal time-independent, corresponds to the fundamental capability bear stresses caused external forces. Sufficiently long-time (24 h) stress relaxation tes...

We have measured the magnetic susceptibility, the Hall coefficient and the electrical resistivity of liquid transition metals Fe, Co and Ni alloyed with normal metals. Up to now the investigated alloys can be divided into two groups according to the behaviour of the magnetic susceptibility. The typical behaviour is represented by the liquid alloys of Co-Ge and Au-Ni. In the first group the magn...

Austenitic carbon steels that exhibit excellent mechanical properties due to the twinning-induced plasticity effect have been studied extensively. On the other hand, austenitic stainless steels usually achieve good strength and ductility via transformation-induced plasticity. However, relying on martensite transformation for strength may cause problems such as delayed cracking. Therefore, the t...

Aluminum alloys with nanocrystalline (NC) and ultrafine grain (UFG) size are of interest because of their strengths that are typically 30 pct greater than conventionally processed alloys of the same composition. In this study, UFG AA 5083 plate was prepared by quasi-isostatic (QI) forging of cryomilled powder, and the microstructure and mechanical behavior was investigated and compared with the...

We peruse various anomalous physical responses of the cubic (ferromagnetic SrRuO3 and paramagnetic CaRuO3) ruthenates, such as fractional power-law conductivity, anomalous Raman line shapes, and Hall currents. We show how these exciting power-law observations are naturally described within a new, local (orbital) non-Fermi-liquid state arising from strong, multiorbital Coulomb interactions. Intr...

We present a microscopic description of edge excitations in the quantum Hall effect which is analogous to Feynman’s theory of superfluids. Analytic expressions for the excitation energies are derived in finite dots. Our predictions are in excellent agreement with the results of a recent numerical diagonalization. In the large N limit the dispersion law is proportional to qlog 1 q . For short ra...

This paper is proposing to the scientific community a new, original approach to the problem of the bio-mechanical and tensile study of the human cornea. By overturning the traditional “classic” approach, focusing mainly on the analysis of the collagen fibril composition and distribution, and on the yield stress of the Stroma only (in the wrong assumption of its alleged “major importance”, as a ...
