The processes leading to the exceptionally hard radio spectra of pulsar-wind nebulae (PWNe) are not yet understood. Radio photon spectral indices among $29$ PWNe from literature show an approximately normal, $\alpha=0.2\pm0.2$ distribution. We present $\sim 3\sigma$ evidence for a distinct sub-population PWNe, with spectrum $\alpha=0.01\pm0.06$ near termination shock and significantly softer el...

The purpose of this study was to evaluate the preoperative radiographs with cases of developmental dysplasia of the hip (DDH) leading to rotational acetabular osteotomy (RAO) or curved peri-acetabular osteotomy (CPO), and examine the frequency of femoroacetabular impingement (FAI) related bone morphology in the acetabulum and femoral head-neck junction. Twenty-four hips with hip dyaplasia who u...

BACKGROUND Patients with symptomatic femoroacetabular impingement (FAI) frequently have bilateral deformity and inquire about the prognosis of their contralateral, asymptomatic hip. Idiopathic coxarthrosis has been established as an independent risk factor for joint failure on the other side. PURPOSE To determine the prevalence of bilateral arthroscopic treatment for FAI and to identify predi...

The exact joint multifractal distribution for the scaling and winding of the electrostatic potential lines near any conformally invariant scaling curve is derived in two dimensions. Its spectrum f(alpha,lambda) gives the Hausdorff dimension of the points where the potential scales with distance r as H approximately r(alpha) while the curve logarithmically spirals with a rotation angle phi=lambd...

It has been found that young guinea pigs when progressing over a surface inclined at an angle alpha with the horizontal, orient upward in a way such that the path described by an oriented animal is at a mean angle theta with the base of the inclined surface. The magnitude of mean theta increases as the angle of inclination alpha increases. The function relating theta and alpha is compound, bein...

UV resonance Raman spectroscopy has been used to determine the conformational energy landscape of poly-L-lysine (PLL) in the presence of NaClO4 as a function of temperature. At 1 degree C, in the presence of 0.83 M NaClO4, PLL shows an approximately 86% alpha-helix-like content, which contains alpha-helix and pi-bulge/helix conformations. The high alpha-helix-like content of PLL occurs because ...

UNLABELLED The latest methods in estimating the probability (absolute risk) of osteoporotic fractures include several logistic regression models, based on qualitative risk factors plus bone mineral density (BMD), and the probability estimate of fracture in the future. The Slovak logistic regression model, in contrast to other models, is created from quantitative variables of the proximal femur ...

Atom is the smallest component of a chemical element that cannot be changed chemically. The concept atom was put forward by several scientists, one which Rutherford. From results Rutherford's experiment, it known most alpha particles fired at thin gold plate are transmitted or scattered with small scattering angle. In this study, effect incident energy (E) on cross section (σ) and angle (Θ) wil...

We propose a method for the generation of transverse valley currents, which is based on pure crossed Andreev reflection (pCAR) in superconducting hybrid junctions composed gapped $\ensuremath{\alpha}\ensuremath{-}{\mathcal{T}}_{3}$ lattices with ferromagnet-induced exchange interaction. The angle-resolved pCAR probability asymmetric given valley, resulting currents zero net charge. This assiste...
