I n the past decades, the effect of different tax amendments on various economic issues has been studied. The majority of these studies have avoided considering shadow economy as part of the calculation and analysis, and an issue, which has received little attention, is the relationship between green tax reforms and shadow economy, as for informal labor, which is well-connected to un...

This paper presents an algorithm that, given an integer n > 1, finds the largest integer k such that n is a kth power. A previous algorithm by the first author took time b1+o(1) where b = lg n; more precisely, time b exp(O( √ lg b lg lg b)); conjecturally, time b(lg b)O(1). The new algorithm takes time b(lg b)O(1). It relies on relatively complicated subroutines—specifically, on the first autho...

Background: Dietary patterns better reflect eating habits as opposed to single dietary components. However, the use of dietary pattern analysis in nutritional epidemiology has been hampered by the complexity of interpreting and presenting multidimensional dietary data. Methods: This study extracts and visualizes dietary patterns from self-reported dietary data collected in mid-pregnancy (25 wee...

The mechanism of the loss of skeletal muscle mass that occurs during spaceflight is not well understood. Myostatin has been proposed as a negative modulator of muscle mass, and IGF-I and IGF-II are known positive regulators of muscle differentiation and growth. We investigated whether muscle loss associated with spaceflight is accompanied by increased levels of myostatin and a reduction in IGF-...

The type-I quantum superalgebras are known to admit non-trivial one-parameter families of inequivalent finite dimensional irreps, even for generic q. We apply the recently developed technique to construct new solutions to the quantum Yang-Baxter equation associated with the one-parameter family of irreps of Uq(gl(m|n)), thus obtaining R-matrices which depend not only on a spectral parameter but...

The Huang-Rhys factor S, the half-width H(T) and the peak position E of the F band are evaluated in terms of the forces that the l s -t 2 p electronic transition induces in the surrounding lattice, and of the phonon projected density of states of the perturbed lattice. The symmetry coordinates of the F-center are explicitly considered ; only T:, T$, T'& are found to occur. H(T) and E are deduce...

Norovirus (NV) and sapovirus (SV) are members of the family Caliciviridae and are etiologic agents for acute gastroenteritis in humans (1,2). Presently, NV is the more causative of the two for the outbreak of gastroenteritis, whereas only a few outbreaks of SV have been reported. Acute gastroenteritis due to SV occurs mainly in infants and young children (2). Previously, we reported on outbreak...

A universal R-matrix for the non-standard (Jordanian) quantum deformation of sl(2, IR) is presented. A family of solutions of the quantum Yang– Baxter equation is obtained from some finite dimensional representations of this Lie bialgebra quantization of sl(2, IR). The quantum Yang–Baxter equation (YBE) R12R13R23 = R23R13R12. (1) was discovered to play a relevant role as the integrability condi...

The blood-brain barrier (BBB) is a paradox. On one hand, it protects the brain from what would otherwise be a constant systemic barrage of noxious substances. On the other hand, it prevents, in large measure, the delivery of therapeutic agents to patients with brain tumors. In an ongoing effort to improve the understanding and clinical consequences of the BBB and its disruption, a 3-day meeting...
