The spots range in latitude\nfrom 10 to 75 degrees and k = 0.090^{+0.006}_{-0.005} -- less than the solar\nvalue but consistent with the younger age of the star. k is also well\nconstrained by the independent spectroscopic estimate of vsini.

The lack of any bright SN down to\nvery strict limits and the vanishing spectral lags are typical of short GRBs,\nstrikingly at odds with the long (102s) duration of this event. Here we present\nspectral and temporal analysis of the Swift observations. We show that the\nburst presents standard optical, UV and X-ray afterglows.

The achromatic behaviour\nand the consistent post-break decay slopes make GRB 060614 one of the best\nexamples of a jet break for a Swift burst. The optical, UV and X-rays afterglow\nlight curves have also an earlier break at ~30 ks. In the optical, there is\nstrong spectral evolution around this break, suggesting the passage of a break\nfrequency through the optical/UV band. The very blue spectrum at early times\nand the trend in the light curves (rising at low frequencies, and decaying at\nhigher energies) suggest this may be the injection frequency. The early X-ray\nlight curve is well interpreted as the X-ray counterpart of the burst extended\nemission. Spectral analysis of BAT/XRT data in the 80s overlap time show that\nthe Ep of the burst has decreased to as low as 8keV at the beginning of the XRT\nobservation. The Ep continues to decrease through the XRT energy band and exits\nit at about 500s after the trigger. The average Ep of the burst is likely < 24\nkeV but larger than 8 keV. The initial peak observed by BAT is however\ndistinctly harder than the rest with Ep ~300 keV as measured by Konus Wind.\nConsidering the time-averaged spectral properties, GRB 060614 is consistent\nwith the Eiso-Ep_rest, Egamma-Ep_rest, and Liso-Ep correlations.\n', '[{\"version\":\"v1\",\"created\":\"Tue, 17 Apr 2007 20:14:33 GMT\"}]', '2007-07-11', '[[\"Mangano\",\"V.\",\"\"],[\"Holland\",\"S.

Geometric considerations indicate that dust formed in the dense swept-up\nshell between the forward and reverse shocks, and not in the freely expanding\nSN ejecta.

Unlike previous works, where a\nnoiseless public discussion channel is used for feedback, the feed-forward and\nfeedback signals share the same noisy channel in the present model. Quite\ninterestingly, this noisy feedback model is shown to be more advantageous in\nthe current setting. More specifically, the discrete memoryless modulo-additive\nchannel with a full-duplex destination node is considered first, and it is\nshown that the judicious use of feedback increases the perfect secrecy capacity\nto the capacity of the source-destination channel in the absence of the\nwiretapper. In the achievability scheme, the feedback signal corresponds to a\nprivate key, known only to the destination. In the half-duplex scheme, a novel\nfeedback technique that always achieves a positive perfect secrecy rate (even\nwhen the source-wiretapper channel is less noisy than the source-destination\nchannel) is proposed. These results hinge on the modulo-additive property of\nthe channel, which is exploited by the destination to perform encryption over\nthe channel without revealing its key to the source. Finally, this scheme is\nextended to the continuous real valued modulo-$\\Lambda$ channel where it is\nshown that the perfect secrecy capacity with feedback is also equal to the\ncapacity in the absence of the wiretapper.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 18 Apr 2007 02:43:40 GMT\"}]', '2016-11-18', '[[\"Lai\",\"Lifeng\",\"\"],[\"Gamal\",\"Hesham El\",\"\"],[\"Poor\",\"H.

The first model represents a stochastically-perturbed flux\ntransport dynamo. Here even very weak stochastic perturbations can give rise to\nsignificant modulation in the activity cycle. This modulation leads to a loss\nof predictability. In the second model, we neglect stochastic effects and\nassume that generation of magnetic field in the Sun can be described by a fully\ndeterministic nonlinear mean-field model -- this is a best case scenario for\nprediction. We designate the output from this deterministic model (with\nparameters chosen to produce chaotically modulated cycles) as a target\ntimeseries that subsequent deterministic mean-field models are required to\npredict. Long-term prediction is impossible even if a model that is correct in\nall details is utilised in the prediction.

This is the case even if the\npredicting model has been tuned to reproduce the output of previous cycles.\nGiven the inherent uncertainties in determining the transport coefficients and\nnonlinear responses for mean-field models, we argue that this makes predicting\nthe solar cycle using the output from such models impossible.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 18 Apr 2007 13:22:23 GMT\"}]', '2009-06-23', '[[\"Bushby\",\"Paul J.\",\"\"],[\"Tobias\",\"Steven M.\",\"\"]]'),

Adequate\nstellar atmosphere models are required for spectral analyses and mass-loss\ndeterminations. Present models can only account for the inhomogeneity of\nstellar winds in the approximation of small-scale structures that are optically\nthin. This treatment of ``microclumping\'\' has led to reducing empirical\nmass-loss rates by factors of two and more. Aims: Stellar wind clumps can be\noptically thick in spectral lines. We investigate how this ``macroclumping\'\'\nimpacts on empirical mass-loss rates. Methods: The Potsdam Wolf-Rayet (PoWR)\nmodel atmosphere code is generalized in the ``formal integral\'\' to account for\nclumps that are not necessarily optically thin. Results: Optically thick clumps\nreduce the effective opacity. This has a pronounced effect on the emergent\nspectrum. Our modeling for the O-type supergiant zeta Puppis reveals that the\noptically thin H-alpha line is not affected by wind porosity, but that the PV\nresonance doublet becomes significantly weaker when macroclumping is taken into\naccount. The reported discrepancies between resonance-line and\nrecombination-line diagnostics can be resolved entirely with the macroclumping\nmodeling without downward revision of the mass-loss rate. Conclusions:\nMass-loss rates inferred from optically thin emission, such as the H-alpha line\nin O stars, are not influenced by macroclumping. The strength of optically\nthick lines, however, is reduced because of the porosity effects. Therefore,\nneglecting the porosity in stellar wind modeling can lead to underestimating\nempirical mass-loss rates.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 18 Apr 2007 17:13:22 GMT\"},{\"version\":\"v2\",\"created\":\"Tue, 20 Nov 2007 12:59:39 GMT\"}]', '2007-11-20', '[[\"Oskinova\",\"L.

Valenti & Fischer\n(2005) provide age and metallicity estimates for 1039 FGK dwarfs in the Solar\nNeighbourhood. Using the Hipparcos catalogue as a reference to calibrate\npotential biases, we have extracted volume-limited samples of nearby stars from\nthe Valenti-Fischer dataset. Unlike other recent investigations, our analysis\nshows clear evidence for an age-metallicity relation in the local disk, albeit\nwith substantial dispersion at any epoch. The mean metallicity increases from\n-0.3 dex at a lookback time of ~10 Gyrs to +0.15 dex at the present day.\nSupplementing the Valenti-Fischer measurements with literature data to give a\ncomplete volume-limited sample, the age distribution of nearby FGK dwarfs is\nbroadly consistent with a uniform star-formation rate over the history of the\nGalactic disk. In striking contrast, most stars known to have planetary\ncompanions are younger than 5 Gyrs; however, stars with planetary companions\nwithin 0.4 AU have a significantly flatter age distribution, indicating that\nthose systems are stable on timescales of many Gyrs. Several of the older,\nlower metallicity host stars have enhanced [alpha/Fe] ratios, implying\nmembership of the thick disk. If the frequency of terrestrial planets is also\ncorrelated with stellar metallicity, then the median age of such planetary\nsystem is likely to be ~3 Gyrs. We discuss the implications of this hypothesis\nin designing searches for Earth analogues among the nearby stars.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 18 Apr 2007 20:11:57 GMT\"}]', '2009-06-23', '[[\"Reid\",\"I.
