This study compares virial masses to masses deduced\nfrom millimeter emission, in two GMC samples: the local molecular clouds in our\nGalaxy and their equivalents in the Small Magellanic Cloud (SMC), one of the\nnearest low metallicity dwarf galaxy. In our Galaxy, mass estimates deduced\nfrom millimeter emission are consistent with masses deduced from gamma ray\nanalysis and trace the total mass of the clouds. Virial masses are\nsystematically larger (twice on average) than mass estimates from millimeter\ndust emission. This difference decreases toward high masses and has already\nbeen reported in previous studies. In the SMC however, molecular cloud masses\ndeduced from SIMBA millimeter observations are systematically higher (twice on\naverage for conservative values of the dust to gas ratio and dust emissivity)\nthan the virial masses from SEST CO observations. The observed excess can not\nbe accounted for by any plausible change of dust properties. Taking a general\nform for the virial theorem, we show that a magnetic field strength of ~15\nmicro Gauss in SMC clouds could provide additional support to the clouds and\nexplain the difference observed.

We\nshow that for any growing cells whose gene expression is under stochastic\nfluctuations, adaptive cellular state is inevitably selected by noise, even\nwithout specific signal transduction network for it. In general, changes in\nprotein concentration in a cell are given by its synthesis minus dilution and\ndegradation, both of which are proportional to the rate of cell growth. In an\nadaptive state with a higher growth speed, both terms are large and balanced.\nUnder the presence of noise in gene expression, the adaptive state is less\naffected by stochasticity since both the synthesis and dilution terms are\nlarge, while for a non-adaptive state both the terms are smaller so that cells\nare easily kicked out of the original state by noise. Hence, escape time from a\ncellular state and the cellular growth rate are negatively correlated. This\nleads to a selection of adaptive states with higher growth rates, and model\nsimulations confirm this selection to take place in general.

Observational tests concern the distribution of images of discrete\ncosmic objects or more global effects, mainly those concerning the Cosmic\nMicrowave Background. According to the 2003-2006 WMAP data releases, various\ndeviations from the flat infinite universe model predictions hint at a possible\nnon-trivial topology for the shape of space. In particular, a finite universe\nwith the topology of the Poincar\\\'e dodecahedral spherical space fits\nremarkably well the data and is a good candidate for explaining both the local\ncurvature of space and the large angle anomalies in the temperature power\nspectrum. Such a model of a small universe, whose volume would represent only\nabout 80% the volume of the observable universe, offers an observational\nsignature in the form of a predictable topological lens effect on one hand, and\nrises new issues on the physics of the early universe on the other hand.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 25 Apr 2007 13:48:18 GMT\"}]', '2007-05-23', '[[\"Luminet\",\"Jean-Pierre\",\"\"]]'),

Sensing capacity is defined as the maximum number of signal dimensions\nreliably identified per sensor observation. In this context sparsity of the\nphenomena is a key feature that determines sensing capacity. Precluding the SNR\nof the environment the effect of sparsity on the number of measurements\nrequired for accurate reconstruction of a sparse phenomena has been widely\ndealt with under compressed sensing. Nevertheless the development there was\nmotivated from an algorithmic perspective. In this paper our aim is to derive\nthese bounds in an information theoretic set-up and thus provide algorithm\nindependent conditions for reliable reconstruction of sparse signals. In this\ndirection we first generalize the Fano\'s inequality and provide lower bounds to\nthe probability of error in reconstruction subject to an arbitrary distortion\ncriteria. Using these lower bounds to the probability of error, we derive upper\nbounds to sensing capacity and show that for fixed SNR regime sensing capacity\ngoes down to zero as sparsity goes down to zero. This means that\ndisproportionately more sensors are required to monitor very sparse events. Our\nnext main contribution is that we show the effect of sensing diversity on\nsensing capacity, an effect that has not been considered before. Sensing\ndiversity is related to the effective \\emph{coverage} of a sensor with respect\nto the field. In this direction we show the following results (a) Sensing\ncapacity goes down as sensing diversity per sensor goes down; (b) Random\nsampling (coverage) of the field by sensors is better than contiguous location\nsampling (coverage).\n', '[{\"version\":\"v1\",\"created\":\"Wed, 25 Apr 2007 19:52:47 GMT\"},{\"version\":\"v2\",\"created\":\"Mon, 14 May 2007 19:08:44 GMT\"},{\"version\":\"v3\",\"created\":\"Mon, 4 Jun 2007 18:21:46 GMT\"}]', '2007-07-13', '[[\"Aeron\",\"Shuchin\",\"\"],[\"Zhao\",\"Manqi\",\"\"],[\"Saligrama\",\"Venkatesh\",\"\"]]'),

From these correlations\nP_R is also expected to scale with M_H and sigma_H and this is confirmed by our\nanalysis.

A byproduct correlation between R_H\nand sigma_H is also found, and can be further tested by optical studies. In\naddition, we find that observationally R_H scales non-linearly with the virial\nradius of the host cluster, and this immediately means that the fraction of the\ncluster volume which is radio emitting increases with cluster mass and thus\nthat the non-thermal component in clusters is not self-similar.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 26 Apr 2007 07:59:10 GMT\"}]', '2009-06-23', '[[\"Cassano\",\"R.\",\"\"],[\"Brunetti\",\"G.\",\"\"],[\"Setti\",\"G.\",\"\"],[\"Govoni\",\"F.\",\"\"],[\"Dolag\",\"K.\",\"\"]]'),

The system exhibits total eclipses and, based on the measured\nsystemic velocity and the derived distance, is a member of the globular cluster\nomega Cen. We obtain 0.945 +/- 0.043 Msun, 0.983 +/- 0.015 Rsun and 6.68 +/-\n0.88 Lsun for the cooler, but larger and more luminous primary component. The\nsecondary component has 0.144 +/- 0.008 Msun, 0.425 +/- 0.008 Rsun and 2.26 +/-\n0.28 Lsun. The effective temperatures are estimated at 9370 K for the primary\nand at 10866 K for the secondary. On the color-magnitude diagram of the\ncluster, the primary component occupies a position between the tip of the blue\nstraggler region and the extended horizontal branch while the secondary\ncomponent is located close to the red border of the area occupied by hot\nsubdwarfs. However, its radius is too large and its effective temperature is\ntoo low for it to be an sdB star. We propose a scenario leading to the\nformation of a system with such unusual properties with the primary component\n``re-born\'\' from a former white dwarf which accreted a new envelope through\nmass transfer from its companion. The secondary star has lost most of its\nenvelope while starting its ascent onto the sub-giant branch.

Here we consider in detail the radiation processes\ndue to both electrons and hadrons accelerated inside the open cluster. As a\nspecific scenario, we apply the acceleration process at the shocks arising in\nthe winds of WR type stars. Particles diffuse through the medium of the open\ncluster during the activity time of the acceleration scenario defined by the\nage of the WR star.
