When n identical randomly located nodes, each capable of transmitting at W bits/sec and using a xed range, form a wireless network, the throughput (n) obtainable by each node for a randomly chosen destination is ( W p n log n ) bits/sec under a non-interference protocol. If the nodes are optimally placed in a disk of unit area, traÆc patterns are optimally assigned, and each transmission's rang...
BACKGROUND There is a debate regarding the management of ovarian immature teratomas (ITs). In adult women, postoperative chemotherapy is standard except for stage I, grade 1 disease, whereas surgery alone is standard in pediatric patients. To determine the role of chemotherapy, a pooled analysis of pediatric and adult clinical trials was conducted. METHODS Data from 7 pediatric trials and 2 a...
BACKGROUND The frequency of mild-to-moderate adverse events following smallpox vaccination was not well documented or reported during the pre-eradication era. This report describes the frequency of such symptoms among 936 adult smallpox vaccinees with and without a history of prior smallpox vaccination. METHODS Diary cards were distributed to 1006 laboratory workers and members of the Centers...
BACKGROUND It is unclear whether metabolic or body composition effects differ between protease inhibitor-based regimens recommended for initial treatment of human immunodeficiency virus (HIV) infection. METHODS ATADAR is a phase 4, open-label, multicenter, randomized clinical trial. Stable antiretroviral-naive HIV-infected adults were randomly assigned to atazanavir/ritonavir 300/100 mg or da...
BACKGROUND Recent advances in schizophrenia genetics are shedding new light on etiopathogenesis, but issues germane to translation of findings into clinical practice are relatively understudied. We assessed the need for, and efficacy of, a contemporary genetic counseling protocol for individuals with schizophrenia. METHODS After characterizing rare copy number variation in a cohort of adults ...
V irtually every organization has a performance management system that is expected to accomplish a number of important objectives with respect to human capital management. The objectives often include motivating performance, helping individuals develop their skills, building a performance culture, determining who should be promoted, eliminating individuals who are poor performers, and helping i...
The article presents a numerical inversion method for estimation of quality Q factor and phase velocity in linear, viscoelastic, isotropic media using reconstruction of relaxation spectrum from measured or computed complex velocity or modulus of the medium. Mathematically, the problem is formulated as an inverse problem for reconstruction of relaxation spectrum in the analytic Stieltjes represe...
Members of the class Epsilonproteobacteria are known to be of major importance in biogeochemical processes at oxic-anoxic interfaces. In pelagic redoxclines of the central Baltic Sea, an uncultured epsilonproteobacterium related to Sulfurimonas denitrificans was proposed to play a key role in chemolithotrophic denitrification (I. Brettar, M. Labrenz, S. Flavier, J. Bötel, H. Kuosa, R. Christen,...
M layoffs in the 1980s and 1990s spawned a renewed interest in the effects of unemployment not seen since the Depression. Consistent with this focus, however, laid-off managers weren’t studied much after they had obtained new jobs. Reemployment signaled that a new, if somewhat different, equilibrium in employees’ careers had been restored. More recently, though, greater attention is being paid ...
In recent years, considerable effort has gone into understanding default reasoning. Most of this effort concentrated on the question of entailment, i.e., what conclusions are warranted by a knowledge-base of defaults. Surprisingly, few works formally examine the general role of defaults. We argue that an examination of this role is necessary in order to understand defaults, and suggest a concre...
