A methodology for efficiently integrating geosynchronous satellite links into communications networkx by employing modern digital technology, in particular the asynchronous transfer mode (ATM), is explained. The concept of seamless interoperability is examined, and a vital C41 U.S. Army network (the Warfighter Information Network) which will employ ATM is described. ATM cell structure is explai...

In this paper I propose to estimate densities with possibly restricted support semi-nonparametrically (SNP) using SNP densities on the unit interval based on orthonormal Legendre polynomials. This approach will be applied to the interval censored mixed proportional hazard (ICMPH) model, where the distribution of the unobserved heterogeneity is modeled semi-nonparametrically. Various conditions ...

Heit B, Yeung T, Grinstein S. Changes in mitochondrial surface charge mediate recruitment of signalling molecules during apoptosis. Am J Physiol Cell Physiol 300: C33–C41, 2011. First published October 6, 2010; doi:10.1152/ajpcell.00139.2010.—Electrostatic interactions with negative lipids contribute to the subcellular localization of polycationic proteins. In situ measurements using cytosolic ...

A Simple Approach to Treatment Effects on Durations When the Treatment Timing is Chosen When a treatment unambiguously defines the treatment and control groups at a given time point, its effects are usually found by comparing the two groups’ mean responses. But there are many cases where the treatment timing is chosen, for which the conventional approach fails. This paper sets up an ideal causa...

Transitions to Stable and Unstable Jobs Before and During the Crisis Using administrative records data from Spanish Social Security, we analyse the pattern and the determinants of individual unemployment benefit spell durations. We compare a period of expansion (2005-2007) and the recent recession (2009-2011), allowing us to determine the impact of the current crisis. In line with the duality t...

Amphotericin B (AmB) exerts its antifungal activity by forming ion-permeable assemblies across lipid bilayers. To investigate AmB-AmB bimolecular interactions in the assembly, we carried out (13)C{(19)F}REDOR experiments using 14-(19)F- and (13)C41-labeled AmBs in sterol-containing and sterol-free palmitoyloleoylphosphatidylcholine (POPC) membranes and measured the average distance between the ...

Viral myocarditis (VMC) most prevalently caused by coxsackievirus B3 (CVB3) infection is characterized by severe cardiac inflammation. Therapeutic options for the disease are still limited. Astragaloside IV (AST-IV), a purified small molecular saponin (C41 H68 O14 , MW 784), is the main active component of Chinese medical herb Astragalus which has been empirically prescribed for the treatment o...

Assessing the Effect of Mother’s Migration on Childhood Mortality in the Informal Settlements of Nairobi Between one and two million migrants reside in cramped conditions in Nairobi’s slums without proper access to sanitation or affordable clean water. Children in such areas are exposed to enormous risks, health risks in particular. Using longitudinal data collected every four months during the...

A new semiparametric proportional hazard rate model is proposed which extends standard models to include a dynamic speci cation. Two main problems are resolved in the course of this paper. First, the partial likelihood approach to estimate the components of a standard proportional hazard model is not available in a dynamic model involving lags of the log integrated baseline hazard. We use a dis...

We analyze the factors determining Mexican migration decision to the United States, focusing on the causal effect of family networks on the timing of a Mexican household head’s migration. This paper contributes to the migrant network literature on relating family members’ migration as a channel to the migrant networks and showing the econometric problems if the correlated migration behavior bet...
