Strong turbulence causes phase discontinuities known as branch points in an optical field. These discontinuities complicate the phase unwrapping necessary to apply phase corrections onto a deformable mirror in an adaptive optics (AO) system. This paper proposes a non-optimal but effective and implementable phase unwrapping method for optical fields containing branch points. This method first ap...

OBJECTIVES The magnitude of HIV viral rebound following ART cessation has consequences for clinical outcome and onward transmission. We compared plasma viral load (pVL) rebound after stopping ART initiated in primary (PHI) and chronic HIV infection (CHI). DESIGN Two populations with protocol-indicated ART cessation from SPARTAC (PHI, n = 182) and SMART (CHI, n = 1450) trials. METHODS Time f...

With the implementation of universal newborn hearing screening (UNHS) programmes and early diagnosis and treatment of hearing problems, the need has clearly emerged to implement and carry out a systematic and coordinated protocol for the aetiological diagnosis of permanent hearing impairment (PHI). Within the framework of the Italian Ministry of Health project CCM 2013 "Preventing Communication...

This study has used in vitro techniques to investigate the potential interactions between mouse pancreatic islet cells and syngeneic macrophages (M phi). Islets strongly stimulated M phi migration from agarose microdroplets; insulin was the only one of four islet cell hormones tested that was effective individually. Chronic exposure of islet monolayers to recombinant mouse IL-1, an M phi secret...

A vertical line stimulus was presented alternately at two positions on an oscilloscope face, with no interstimulus interval. Observation of this stimulus produced haphazard alternation between a number of movement percepts, which were divided into four categories: phi, omega and partial movement, and no movement. Attention to one category did not increase the proportion of time movement in that...

Let $r>0, n\in\mathbb N, {\bf k}\in\mathbb N$. Consider the delay differential equation $$ x'(t)=g(x(t-d_1(Lx_t)),\ldots,x(t-d_{{\bf k}}(Lx_t))) for $g:( \mathbb R^n)^{{\bf k}}\supset V\to\mathbb R^n$ continuously differentiable, $L$ a continuous linear map from $C([-r,0],\mathbb R^n)$ into finite-dimensional vector-space $F$, each $d_k:F\supset W\to[0,r]$, $k=1,\ldots,{\bf k}$, and $x_t(s)=x(t...

In this paper, the geometry of quantum gravity is quantized in sense being noncommutative (first quantization) but it also emergent (second quantization). A new mechanism for proposed which can emerge from “one-matrix multitrace scalar matrix models” by probing statistical physics commutative phases matter. This contrast to usual emerges “many-matrix singletrace Yang–Mills gauge theory. novel s...

The paper demonstrates the optimization of the execution environment of a hybrid OpenMP+MPI computational fluid dynamics code (shallow water equation solver) on a cluster enabled with Intel Xeon Phi coprocessors. The discussion includes: 1. Controlling the number and affinity of OpenMP threads to optimize access to memory bandwidth; 2. Tuning the inter-operation of OpenMP and MPI to partition t...

Let $$(M^{n},g,e^{-\phi }dv)$$ be a weighted Riemannian manifold evolving by geometric flow $$\frac{\partial g}{\partial t}=2\,h(t),\,\,\,\frac{\partial \phi }{\partial t}=\Delta $$ . In this paper, we obtain series of space-time gradient estimates for positive solutions parabolic partial equation $$\begin{aligned} (\Delta _{\phi }-\partial _{t})u(x,t)=q(x,t)u^{a+1}(x,t)+p(x,t)A(u(x,t))),\,\,\,...
