Therefore, many more redshifts than blueshifts should be\nobserved for galaxies and supernovae, etc in the sky. This conclusion agrees\nwith current observations. The estimated value of the redshift constant beta of\nthe dark matter field fluid is in the range of 10^(-3) ~ 10^(-5)/Mpc. A large\nredshift value from a distant celestial object may not necessarily indicate\nthat it has a large receding speed. Based on the redshift effect of dark matter\nfield fluid, it is concluded that at least in time average all photons have the\nsame geometry (size and shape) in all inertial reference frames and do not have\nlength contraction effect.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 9 Apr 2007 12:18:23 GMT\"}]', '2007-05-23', '[[\"Pan\",\"Hongjun\",\"\"]]'),

A number of characteristics of purely quantum nature are found: The\nin-plane interaction s_i^x s_j^x + s_i^y s_j^y induces an antiferromagnetic\ncorrelation in the out-of-plane s_i^z component, at higher temperatures in the\nantiferromagnetic XXZ chain, dominantly at low temperatures in the\nferromagnetic XXZ chain, and, in-between, at all temperatures in the XY chain.\nWe find that the converse effect also occurs in the antiferromagnetic XXZ\nchain: an antiferromagnetic s_i^z s_j^z interaction induces a correlation in\nthe s_i^xy component. As another purely quantum effect, (i) in the\nantiferromagnet, the value of the specific heat peak is insensitive to\nanisotropy and the temperature of the specific heat peak decreases from the\nisotropic (Heisenberg) with introduction of either type (Ising or XY)\nanisotropy; (ii) in complete contrast, in the ferromagnet, the value and\ntemperature of the specific heat peak increase with either type of anisotropy.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 9 Apr 2007 19:05:01 GMT\"},{\"version\":\"v2\",\"created\":\"Thu, 24 Apr 2008 06:07:03 GMT\"}]', '2009-11-13', '[[\"Sariyer\",\"Ozan S.\",\"\"],[\"Berker\",\"A.

For regular boundaries this flow has a large\nvariety of fixed points and no cyclic orbit. The family of fixed points\nincludes Neumann and Dirichlet boundary conditions. In one-dimensional field\ntheories pseudoperiodic and quasiperiodic boundary conditions are also RG fixed\npoints. Under these conditions massless bosonic free field theories are\nconformally invariant. Among all fixed points only Neumann boundary conditions\nare infrared stable fixed points. All other conformal invariant boundary\nconditions become unstable under some relevant perturbations. In finite volumes\nwe analyse the dependence of the vacuum energy along the trajectories of the\nrenormalization group flow providing an interesting framework for dark energy\nevolution.

A distinctive feature of\nthis study is that the spin-rich $qqq$ force is generated by a $ggg$ vertex (a\ngenuine part of the QCD Lagrangian) wherein the 3 radiating gluon lines end on\nas many quark lines, giving rise to a (Mercedes-Benz type) $Y$-shaped diagram.\nThe dynamics is that of a Salpeter-like equation (3D support for the kernel)\nformulated covariantly on the light front, a la Markov-Yukawa Transversality\nPrinciple (MYTP) which warrants a 2-way interconnection between the 3D and 4D\nBethe-Salpeter (BSE) forms for 2 as well as 3 fermion quarks. With these\ningredients, the differential equation for the 3D wave function $\\phi$ receives\nwell-defined contributions from the $qq$ and $qqq$ forces. In particular a\n$negative$ eigenvalue of the spin operator $i \\sigma_1.\\sigma_2\\times \\sigma_3$\nwhich is an integral part of the $qqq$ force, causes a characteristic\nsingularity in the differential equation, signalling the dynamical effect of a\nspin-rich $qqq$ force not yet considered in the literature. The potentially\ncrucial role of this interesting effect vis-a-vis the so-called `spin anomaly\'\nof the proton, is a subject of considerable physical interest.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 9 Apr 2007 13:08:21 GMT\"}]', '2009-04-21', '[[\"Mitra\",\"A.

This task is\nfacilitated if these noises are dynamically generated by means of stochastic\ndifferential equations (SDE) driven by white noises. One such case is that of\nOrnstein--Uhlenbeck noises which are stationary, with Gaussian pdf and a\nvariance reduced by the self-correlation time (\\tau), and whose effect on the\nNIPT phase diagram has been studied some time ago. Another such case is when\nthe stationary pdf is a (colored) Tsallis\' (q)--\\emph{Gaussian} which, being a\n\\emph{fat-tail} distribution for (q>1) and a \\emph{compact-support} one for\n(q<1), allows for a controlled exploration of the effects of the departure from\nGaussian statistics. As done before with stochastic resonance and other\nphenomena, we now exploit this tool to study--within a simple mean-field\napproximation and with an emphasis on the \\emph{order parameter} and the\n``\\emph{susceptibility}\'\'--the combined effect on NIPT of the noises\'\nstatistics and spectrum. Even for relatively small (\\tau), it is shown that\nwhereas fat-tail noise distributions ((q>1)) counteract the effect of\nself-correlation, compact-support ones ((q<1)) enhance it. Also, an interesting\neffect on the susceptibility is seen in the last case.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 9 Apr 2007 21:08:30 GMT\"}]', '2016-08-14', '[[\"Deza\",\"Roberto R.\",\"\"],[\"Wio\",\"Horacio S.\",\"\"],[\"Fuentes\",\"Miguel A.\",\"\"]]'),

We\nassume that a fraction of jet energy, which is generated by an AGN, is\ntransferred to the surrounding gas as thermal energy. Combining a theoretical\nmodel of mass accretion onto black holes with a multiphase description of\nstar-forming gas, we self-consistently follow evolution of both galaxies and\ntheir central black holes. The novelty in our model is that we consider two\ndistinct accretion modes: standard radiatively efficient thin accretion disks\nand radiatively inefficient accretion flows which we will generically refer to\nas RIAFs; motivated by theoretical models for jet production in accretion\ndisks, we assume that only the RIAF is responsible for the AGN feedback. We\nfind that, after an initial episode of bursting star formation, the accretion\nrate onto the central black hole drops so that the accretion disk switches to a\nRIAF structure. At this point, the feedback from the AGN becomes efficient and\nslightly suppresses star formation in the galactic disk and almost completely\nhalts star formation in the bulge. As a result, the nucleus becomes a\nstochastically fuelled low-luminosity AGN (Seyfert galaxy) with recurrent\nshort-lived episodes of activity after the star bursts. Our model predicts\nseveral properties of the low-luminosity AGN including the bolometric\nluminosity, jet powers, the effect on kpc-scale of the radio jet and the AGN\nlifetime, which are in broad agreement with observations of Seyfert galaxies\nand their radio activity.

Afterward, the\nspace of solutions condenses over a finite number of the largest states and\nconsequently the total entropy of solutions becomes smaller than the annealed\none. Another transition takes place when in all the entropically dominant\nstates a finite fraction of nodes freezes so that each of these nodes is\nallowed a single color in all the solutions inside the state. Eventually, above\nthe coloring threshold, no more solutions are available. We compute all the\ncritical connectivities for Erdos-Renyi and regular random graphs and determine\ntheir asymptotic values for large number of colors.\n  Finally, we discuss the algorithmic consequences of our findings.

Recently, Mintert {\\em et al.} proposed generalizations of Wootters\nconcurrence for multipartite states. These MKB concurrences possess a\nmathematical property that enables one to understand the origin of this\ncharacteristic behavior.

Next, we show that the six-qubit Heisenberg XY chain possesses\nproperties necessary for it to have the characteristic behavior too. Most\nimportantly, it is possible to directly measure the multipartite MKB\nconcurrences of pure states.

We compare the results with those from AM Her stars\nand deduce that the blackbody emission arises from reprocessing of hard X-rays,\nrather than from the blobby accretion sometimes seen in AM Hers. Whether an IP\nshows a blackbody component appears to depend primarily on geometric factors: a\nblackbody is not seen in those that have accretion footprints that are always\nobscured by accretion curtains or are only visible when foreshortened on the\nwhite-dwarf limb. Thus we argue against previous suggestions that the blackbody\nemission characterises a separate sub-group of IPs which are more akin to AM\nHers, and develop a unified picture of the blackbody emission in these stars.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 11 Apr 2007 10:11:33 GMT\"}]', '2009-06-23', '[[\"Evans\",\"P.
