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.

For 100 gauge configurations generated with\nsingle-plaquette action at beta = 7.2 on the 32^3 x 60 lattice, we compute\npoint-to-point quark propagators for 33 quark masses in the range [0.01, 0.85],\nand measure the time-correlation functions of pseudoscalar and vector mesons.\nThe inverse lattice spacing and the charm quark bare mass are determined using\nthe mass and decay constant of eta_c(2980). The bare masses of s and b quarks\nare chosen such that the masses of the corresponding vector mesons are in good\nagreement with phi(1020), and Upsilon(9460) respectively.

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. They interact with the matter and radiation, at first\ninside the open cluster and, later in the dense surrounding clouds.

It is assumed that the\nhigh energy phenomena, observed from the X-ray up to the GeV-TeV gamma-ray\nenergies, are related to each other. We conclude that the most likely\ndescription of the radiation processes in these objects is achieved in the\nhybrid (leptonic-hadronic) model in which leptons are responsible for the\nobserved X-ray and GeV gamma-ray emission and hadrons are responsible for the\nTeV gamma-ray emission, which is produced directly inside and in dense clouds\nsurrounding the open cluster.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 26 Apr 2007 11:34:54 GMT\"},{\"version\":\"v2\",\"created\":\"Mon, 20 Aug 2007 13:34:14 GMT\"}]', '2013-06-21', '[[\"Bednarek\",\"W.\",\"\"]]'),

Tc of MgB2 crystals with simultaneously substituted Li for\nMg and C for B decreases more than in the case where C is substituted alone.\nThis means that holes introduced by Li cannot counterbalance the effect of\ndecrease of Tc caused by introduction of electrons coming from C. The possible\nreason of it can be that holes coming from Li occupy the pi band while\nelectrons coming from C fill the sigma band.

This indicates\nenhanced scattering due to defects introduced by substitutions including\ndistortion of the lattice. The observed behavior can be explained as a result\nof two effects, influencing both Tc and Hc2.

M. Abe\ngave a recursive realization of the boson by formal infinite sums of the\ncanonical generators of the Cuntz algebra ${\\cal O}_{\\infty}$. We show that\nsuch formal infinite sum always makes sense on a certain dense subspace of any\npermutative representation of ${\\cal O}_{\\infty}$. In this meaning, we can\nregard as if the algebra ${\\cal B}$ of bosons was a unital $*$-subalgebra of\n${\\cal O}_{\\infty}$ on a given permutative representation by keeping their\nunboundedness. By this relation, we compute branching laws arising from\nrestrictions of representations of ${\\cal O}_{\\infty}$ on ${\\cal B}$. For\nexample, it is shown that the Fock representation of ${\\cal B}$ is given as the\nrestriction of the standard representation of ${\\cal O}_{\\infty}$ on ${\\cal\nB}$.\n', '[{\"version\":\"v1\",\"created\":\"Fri, 27 Apr 2007 04:32:51 GMT\"}]', '2009-11-13', '[[\"Kawamura\",\"Katsunori\",\"\"]]');
