We propose a fast and efficient bispectrum statistic for Cosmic Microwave Background (CMB) temperature anisotropies to constrain the amplitude of the primordial nonGaussian signal measured in terms of the non-linear coupling parameter fNL. We show how the method can achieve a remarkable computational advantage by focussing on subsets of the multipole configurations, where the non-Gaussian signa...

Context. The ROSAT X-ray source 1RXS J141256.0+792204 has recently been identified as a likely compact object whose properties suggest it could be a very nearby radio millisecond pulsar at d = 80 − 260 pc. Aims. We investigated this hypothesis by searching for radio pulsations using the Westerbork Synthesis Radio Telescope. Methods. We observed 1RXS J141256.0+792204 at 385 and 1380 MHz, recordi...

We introduce a novel multi-agent patrolling strategy. By assumption, the swarm of agents performing the task consists of very low capability ant-like agents. The agents have little memory, they can not communicate and their sensing abilities are local. Furthermore, the agents do not posses any knowledge regarding the graph or the swarm size. However, the agents may mark the graph vertices with ...

The analysis of the haplotype-phenotype relationship has become more and more important. We have developed an algorithm, using individual genotypes at linked loci as well as their quantitative phenotypes, to estimate the parameters of the distribution of the phenotypes for subjects with and without a particular haplotype by an expectation-maximization (EM) algorithm. We assumed that the phenoty...

The influence of temperature on contractile performance, total myocardial stiffness, and the elastic and viscous components of stiffness was studied in intact hearts (dog) and isolated cardiac muscle (cat). In 12 dogs on whole-heart bypass, stiffness (AP/AV) was determined by inducing sinusoidal 0.5-ml volume changes in paced, isovolumically contracting left ventricles and measuring the resulta...

The potential role of active state maintenance as a determinant of myocardial oxygen consumption (MVO2) has not been defined. Right ventricular papillary muscles from 15 cats were studied in a polarographic myograph at 23 degrees C in a Krebs-Ringer solution containing 7.5 mM Ca2+ and 10 mM caffeine. MVO2 was determined for isometric tetani at Lmax of 1-5 seconds' duration. Increases in tetanus...

Hypothesis: excessive bronchoconstriction in asthma is due to decreased airway elastance. A.M. Bramley, R.J. Thomson, C.R. Roberts, R.R. Schellenberg. ERS Journals Ltd 1994. ABSTRACT: Based on the strikingly different mechanical properties of airway smooth muscle preparations of different species, we hypothesized that a decrease in the elastance of nonmuscle elements within airway walls of ast...

The contractile state of the noninfarcted myocardium was examined in adult cats after myocardial infarction produced by ligation of several branches of the left coronary artery. At 2 days, 7 days, and 6 weeks after infarction, and after determination of intracardiac pressures, papillary muscles were exicised from the noninfarcted segment of the right ventricle and attached to a myograph for ana...

The throughput capacity of arbitrary wireless networks under the physical Signal to Interference Plus Noise Ratio (SINR) model has received much attention in recent years. In this paper, we investigate the question of how much the worst-case performance of uniform and non-uniform power assignments differ under constraints such as a bound on the area where nodes are distributed or restrictions o...
