We introduce real log canonical threshold and real jumping numbers for real algebraic functions. A real jumping number is a root of the b-function up to a sign if its difference with the minimal one is less than 1. The real log canonical threshold, which is the minimal real jumping number, coincides up to a sign with the maximal pole of the distribution defined by the complex power of the absol...

We prove that if V n is a Chebyshev system on the circle and f is a continuous real-valued function with at least n + 1 sign changes then there exists an orientation preserving diffeomorphism of S that takes f to a function L-orthogonal to V . We also prove that if f is a function on the real projective line with at least four sign changes then there exists an orientation preserving diffeomorph...

Hepatitis B virus (HBV) is a DNA virus that infects the liver as primary target. Currently, a high affinity receptor for HBV is still unknown. The dendritic cell specific C-type lectin DC-SIGN is involved in pathogen recognition through mannose and fucose containing carbohydrates leading to the induction of an anti-viral immune response. Many glycosylated viruses subvert this immune surveillanc...

purpose: to evaluate the range of accommodation lag and it's signs and symptoms in 20-25 year-old female students at zahedan medical school, iran. methods: three-hundred female students were enrolled for assessment of accommodation. after exclusion of individuals with individuals with accommodation disorders in 3 steps including amplitude of accommodation, accommodative facility, and relat...

An important argument in favor of the encyclical theory of the epistle to the Ephesians is based upon the peculiarities found in the epistle itself. Yet these unusual features (e.g., the lack of personal greetings, the unusual statements in 1:15, 3:2, and 4:21, etc.) can all be satisfactorily explained in the light of an original Ephesian destination. After an examination of early scribal habit...

We consider the ǫ-regime of QCD in 3 dimensions. It is shown that the leading term of the effective partition function satisfies a set of Toda lattice equations, recursive in the number of flavors. Taking the replica limit of these Toda equations allows us to derive the microscopic spectral correlation functions for the QCD Dirac operator in 3 dimensions. For an even number of flavors we reprod...

According to ‘standard histories’ of nanotechnology, the colorful pictures of atoms produced by scanning probe microscopists since the 1980s essentially inspired visions of molecular nanotechnology. In this paper, I provide an entirely different account that, nonetheless, refers to aesthetic inspiration. First, I argue that the basic idea of molecular nanotechnology, i.e. producing molecular de...

An historical survey of the approaches to the neural basis of language and the modularity question is summarized. Evidence from aphasia, event-related potentials (ERPs), Specific Language Impairments (SLIs) in children, asymmetry of abilities as shown by linguistic ‘savants’, sign language, separation of conceptual and linguistic knowledge, other disorders such as prosopagnosia and visual agnos...

The overlap Dirac operator in lattice QCD requires the computation of the sign function of a matrix. While this matrix is usually Hermitian, it becomes non-Hermitian in the presence of a quark chemical potential. We show how the action of the sign function of a non-Hermitian matrix on an arbitrary vector can be computed efficiently on large lattices by an iterative method. A Krylov subspace app...
