The energy injected at the outer scale scale has to be converted\ninto heat, which ultimately cannot be done without collisions. A KINETIC\nCASCADE develops that brings the energy to collisional scales both in space and\nvelocity. Its nature depends on the physics of plasma fluctuations.

We find excellent agreement between the\nobserved GCMF -- including its dependence on internal density rho_h, central\nconcentration c, and Galactocentric distance r_gc -- and a simple model in\nwhich the relaxation-driven mass-loss rates of clusters are approximated by\n-dM/dt = mu_ev ~ rho_h^{1/2}. In particular, we recover the well-known\ninsensitivity of M_TO to r_gc. This feature does not derive from a literal\n``universality\'\' of the GCMF turnover mass, but rather from a significant\nvariation of M_TO with rho_h -- the expected outcome of relaxation-driven\ncluster disruption -- plus significant scatter in rho_h as a function of r_gc.\nOur conclusions are the same if the evaporation rates are assumed to depend\ninstead on the mean volume or surface densities of clusters inside their tidal\nradii, as mu_ev ~ rho_t^{1/2} or mu_ev ~ Sigma_t^{3/4} -- alternative\nprescriptions that are physically motivated but involve cluster properties\n(rho_t and Sigma_t) that are not as well defined or as readily observable as\nrho_h.

Here we analyze the performance of\nRandom Vector Quantization (RVQ), in which the precoding matrix is selected\nfrom a random codebook containing independent, isotropically distributed\nentries. We assume that channel elements are i.i.d. and known to the receiver,\nwhich relays the optimal (rate-maximizing) precoder codebook index to the\ntransmitter using B bits. We first derive the large system capacity of\nbeamforming (rank-one precoding matrix) as a function of B, where large system\nrefers to the limit as B and the number of transmit and receive antennas all go\nto infinity with fixed ratios. With beamforming RVQ is asymptotically optimal,\ni.e., no other quantization scheme can achieve a larger asymptotic rate. The\nperformance of RVQ is also compared with that of a simpler reduced-rank scalar\nquantization scheme in which the beamformer is constrained to lie in a random\nsubspace. We subsequently consider a precoding matrix with arbitrary rank, and\napproximate the asymptotic RVQ performance with optimal and linear receivers\n(matched filter and Minimum Mean Squared Error (MMSE)). Numerical examples show\nthat these approximations accurately predict the performance of finite-size\nsystems of interest. Given a target spectral efficiency, numerical examples\nshow that the amount of feedback required by the linear MMSE receiver is only\nslightly more than that required by the optimal receiver, whereas the matched\nfilter can require significantly more feedback.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 2 Apr 2007 15:35:24 GMT\"},{\"version\":\"v2\",\"created\":\"Tue, 17 Feb 2009 03:49:20 GMT\"}]', '2010-08-27', '[[\"Santipach\",\"Wiroonsak\",\"\"],[\"Honig\",\"Michael L.\",\"\"]]'),

X-ray observations reveal a bullet-like subcluster\nwith a prominent bow shock, while lensing results show that the positions of\nthe total mass peaks are consistent with the centroids of the collisionless\ngalaxies (and inconsistent with the X-ray brightness peaks). Previous studies,\nbased on older observational datasets, have placed upper limits on the\nself-interaction cross-section of dark matter per unit mass, sigma/m, using\nsimplified analytic techniques. In this work, we take advantage of new,\nhigher-quality observational datasets by running N-body simulations of\n1E0657-56 that include the effects of self-interacting dark matter, and\ncomparing the results with observations. Furthermore, the recent data allow for\na new independent method of constraining sigma/m, based on the non-observation\nof an offset between the bullet subcluster mass peak and galaxy centroid. This\nnew method places an upper limit (68% confidence) of sigma/m < 1.25 cm^2/g. If\nwe make the assumption that the subcluster and the main cluster had equal\nmass-to-light ratios prior to the merger, we derive our most stringent\nconstraint of sigma/m < 0.7 cm^2/g, which comes from the consistency of the\nsubcluster\'s observed mass-to-light ratio with the main cluster\'s, and with the\nuniversal cluster value, ruling out the possibility of a large fraction of dark\nmatter particles being scattered away due to collisions.

To motivate automated layout for\nquantum circuits, we investigate grid-based layouts and show a performance\nvariance of four times as we vary grid structure and initial qubit placement.\nWe then propose two polynomial-time design heuristics: a greedy algorithm\nsuitable for small, congestion-free quantum circuits and a dataflow-based\nanalysis approach to placement and routing with implicit initial placement of\nqubits. Finally, we show that our dataflow-based heuristic generates better\nlayouts than the state-of-the-art automated grid-based layout and scheduling\nmechanism in terms of latency and potential pipelinability, but at the cost of\nsome area.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 2 Apr 2007 21:31:28 GMT\"}]', '2009-09-29', '[[\"Whitney\",\"Mark\",\"\"],[\"Isailovic\",\"Nemanja\",\"\"],[\"Patel\",\"Yatish\",\"\"],[\"Kubiatowicz\",\"John\",\"\"]]'),

Aims: This motivates planet searches around\nstars which are significantly more massive or less massive than the Sun, and in\nparticular our radial velocity search for planets around very-low mass stars.\nMethods: As part of that program, we obtained measurements of GJ 674, an M2.5\ndwarf at d=4.5 pc, which have a dispersion much in excess of their internal\nerrors. An intensive observing campaign demonstrates that the excess dispersion\nis due to two superimposed coherent signals, with periods of 4.69 and 35 days.\nResults: These data are well described by a 2-planet Keplerian model where each\nplanet has a ~11 Mearth minimum mass. A careful analysis of the (low level)\nmagnetic activity of GJ 674 however demonstrates that the 35-day period\ncoincides with the stellar rotation period. This signal therefore originates in\na spot inhomogeneity modulated by stellar rotation. The 4.69-day signal on the\nother hand is caused by a bona-fide planet, GJ 674b. Conclusion: Its detection\nadds to the growing number of Neptune-mass planets around M-dwarfs, and\nreinforces the emerging conclusion that this mass domain is much more populated\nthan the jovian mass range. We discuss the metallicity distributions of M dwarf\nwith and without planets and find a low 11% probability that they are drawn\nfrom the same parent distribution.

The\nbrightness of UZ Tau E shows significant random variability, but the overall\nperiodic pattern is a broad peak in enhanced brightness, spanning more than\nhalf the binary orbital period. The variability of the H-alpha line is not as\nclearly periodic, but given the sparseness of the data, some periodic component\nis not ruled out.

Our work consists in a detailed study of the microlocal properties,\nwhich rule the spectral stability or instability phenomena appearing under\nsmall perturbations for elliptic quadratic differential operators. The class of\nelliptic quadratic differential operators stands for the class of operators\ndefined in the Weyl quantization by complex-valued elliptic quadratic symbols.\nWe establish in this paper a simple necessary and sufficient condition on the\nWeyl symbol of these operators, which ensures the stability of their spectra.\nWhen this condition is violated, we prove that it occurs some strong spectral\ninstabilities for the high energies of these operators, in some regions which\ncan be far away from their spectra. We give a precise geometrical description\nof them, which explains the results obtained for these operators in some\nnumerical simulations giving the computation of false eigenvalues far from\ntheir spectra by algorithms for eigenvalues computing.\n', '[{\"version\":\"v1\",\"created\":\"Tue, 3 Apr 2007 06:54:27 GMT\"}]', '2007-05-23', '[[\"Pravda-Starov\",\"Karel\",\"\"]]'),

Harmonic modes are excited by the fluctuating drag\nforce, at different wave-numbers. This simple mechanical probe makes it\npossible to measure excitations of the flow at specific scales, averaged over\nspace and time: it is a scale-resolved, global measurement. We also measure the\ndissipation associated to the string motion, and we consider the ratio of the\nfluctuations over dissipation (FDR). In an exploratory approach, we investigate\nthe concept of {\\it effective temperature} defined through the FDR. We compare\nour observations with other definitions of temperature in turbulence. From the\ntheory of Kolmogorov (1941), we derive the exponent -11/3 expected for the\nspectrum of the fluctuations.
