Pharyngeal collapse in patients with obstructive sleep apnea syndrome (OSAS) is linked to decreased upper airway muscle activity. We hypothesised that decreased muscle activity causes decreased stiffness of the upper airway wall and assumed that a decrease in wall stiffness would result in a change point (CP) of the morphology of phase angle time series phi(t) obtained by forced oscillation tec...

Let $mathcal {A} $ and $mathcal {B} $ be C$^*$-algebras. Assume that $mathcal {A}$ is of real rank zero and unital with unit $I$ and $k>0$ is a real number. It is shown that if $Phi:mathcal{A} tomathcal{B}$ is an additive map preserving $|cdot|^k$ for all normal elements; that is, $Phi(|A|^k)=|Phi(A)|^k $ for all normal elements $Ainmathcal A$, $Phi(I)$ is a projection, and there exists a posit...

BACKGROUND Current recommendations regarding posthumous sperm retrieval (PSR) are based on a small number of cases. Our purpose was to determine the time interval from death to a successful procedure. METHODS Seventeen consecutive PSR procedures in 14 deceased and 3 neurologically brain-dead patients at two male infertility centres [Sheba Medical Center (SMC), Tel-Hashomer, Israel and Univers...

Abstract We demonstrate a quasipolynomial-time deterministic approximation algorithm for the partition function of Gibbs point process interacting via stable potential. This result holds all activities $\lambda$ which satisfies zero-free assumption in neighbourhood interval $[0,\lambda ]$ . As corollary, finiterange potentials, we obtain $\lambda \lt 1/(e^{B + 1} \hat C_\phi )$ where $\hat C_\p...

Understanding how quickly landowners regenerate their timberlands after harvest is critical to developing policies to improve forest productivity. Using survey data from 81 counties in Mississippi from 1996 to 2006, this study investigated the length of the time interval between harvest and reforestation. Non-parametric duration analysis was used to examine how long NIPF landowners waited to re...

BACKGROUND The risk/benefit of initiating ART in primary HIV infection (PHI) is unclear. The benefits are more likely to outweigh the risks in patients with severe PHI. An accepted definition of severe PHI is, however, lacking. METHODS CASCADE patients with HIV test interval <6 months were classified as severe and non-severe PHI based on whether the following traits were recorded in the first...

Low-level contrast information in the primary visual pathway is represented in two different channels. ON-center cells signal positive contrasts and OFF-center cells signal negative contrasts. In this study we address the question whether initial motion analysis is performed separately in these two channels, or also through combination of signals from ON and OFF cells. We quantitatively compare...
