Singularity Resolution in Loop Quantum Cosmology: A Brief Overview
Abhay Ashtekar
A brief summary of the singularity resolution in loop quantum cosmology of homogeneous isotropic models is presented. The article is addressed to relativists who do not specialize…
Applicability and non-applicability of equilibrium statistical mechanics to non-thermal damage phenomena: II. Spinodal behavior
S. G. Abaimov
This paper investigates the spinodal behavior of non-thermal damage phenomena. As an example, a non-thermal fiber-bundle model with the global uniform (meanfield) load sharing is c…
Tuning magnetic frustration of nanomagnets in triangular-lattice geometry
Xianglin Ke, Jie Li, Sheng Zhang +3
We study the configuration of magnetic moments on triangular lattices of single-domain ferromagnetic islands, examining the consequences of magnetostatic interactions in this frust…
Search for Primordial Black Holes with SGARFACE
M. Schroedter, F. Krennrich, S. LeBohec +7
The Short GAmma Ray Front Air Cherenkov Experiment (SGARFACE) uses the Whipple 10 m telescope to search for bursts of rays. SGARFACE is sensitive to bursts with duration from a…
Measurement of D+- and D0 production in deep inelastic scattering using a lifetime tag at HERA
ZEUS Collaboration, S. Chekanov
The production of D+- and D0 mesons has been measured with the ZEUS detector at HERA using an integrated luminosity of 133.6 pb-1. The measurements cover the kinematic range 5 < Q^…
Diffraction at TOTEM
G. Antchev, P. Aspell, V. Avati +72
The TOTEM experiment at the LHC measures the total proton-proton cross section with the luminosity-independent method and the elastic proton-proton cross-section over a wide |t|-ra…
Cyclic Inflation
Tirthabir Biswas, Stephon Alexander
We present an inflationary model that is geodesically complete and does not suffer from the transplanckian problem. In most inflationary models, massless (conformal) scalar field f…
Black Hole Spins of Radio Sources
Ruth A. Daly
A new approach to constraining or determining the spin of a massive black hole is proposed. A key parameter in the analysis is the dimensionless ratio, r, of the energy released to…
Subjet distributions in deep inelastic scattering at HERA
ZEUS Collaboration, S. Chekanov
Subjet distributions were measured in neutral current deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 81.7 pb-1. Jets were identified…
Constraints on a phenomenologically parameterized neutron-star equation of state
Jocelyn S. Read, Benjamin D. Lackey, Benjamin J. Owen +1
We introduce a parameterized high-density equation of state (EOS) in order to systematize the study of constraints placed by astrophysical observations on the nature of neutron-sta…
A Factor 3/2 Approximation for Generalized Steiner Tree Problem with Distances One and Two
Piotr Berman, Marek Karpinski, Alex Zelikovsky
We design a 3/2 approximation algorithm for the Generalized Steiner Tree problem (GST) in metrics with distances 1 and 2. This is the first polynomial time approximation algorithm…
On the shape of a rapid hadron in QCD
B. Blok, L. Frankfurt, M. Strikman
We visualize the fundamental property of pQCD: the smaller size of the colorless quark-gluon configurations leads to a more rapid increase of its interaction with energy. Within th…
The Young, Massive, Star Cluster Sandage-96 After the Explosion of SN 2004dj in NGC 2403
J. Vinko, K. Sarneczky, Z. Balog +12
The bright Type II-plateau supernova (SN) 2004dj occurred within the young, massive stellar cluster Sandage-96 in a spiral arm of NGC 2403. New multi-wavelength observations obtain…
Structures and topological transitions of hydrocarbon films on quasicrystalline surfaces
Wahyu Setyawan, Renee D. Diehl, Stefano Curtarolo
Lubricants can affect quasicrystalline coatings surfaces by modifying commensurability of the interfaces. We report results of the first computer simulation studies of physically a…
On the inapplicability of a negative-phase-velocity condition as a negative-refraction condition for active materials
A. Lakhtakia, T. G. Mackay, J. B. Geddes
A negative-phase-velocity condition derived by Depine and Lakhtakia [Microwave Opt Technol Lett 41 (2004) 315] for isotropic, homogeneous, passive, dielectric-magnetic materials is…
Discovery of Very High-Energy Gamma-Ray Radiation from the BL Lac 1ES 0806+524
VERITAS Collaboration, V. Acciari, E. Aliu +90
The high-frequency-peaked BL-Lacertae object \objectname{1ES 0806+524}, at redshift z=0.138, was observed in the very-high-energy (VHE) gamma-ray regime by VERITAS between November…
Jet breaks and Energetics of Swift GRB X-ray Afterglows
J. L. Racusin, E. W. Liang, D. N. Burrows +6
We present a systematic temporal and spectral study of all Swift-XRT observations of GRB afterglows discovered between 2005 January and 2007 December. After constructing and fittin…
Measurement of charged current deep inelastic scattering cross sections with a longitudinally polarised electron beam at HERA
ZEUS Collaboration
Measurements of the cross sections for charged current deep inelastic scattering in e-p collisions with longitudinally polarised electron beams are presented. The measurements are…

P. A. Evans, A. P. Beardmore, K. L. Page +22
We present a homogeneous X-ray analysis of all 318 Gamma Ray Bursts detected by the X-ray Telescope on the Swift satellite up to 2008 July 23; this represents the largest sample of…
Statistical Properties of Gamma-Ray Burst Polarization
Kenji Toma, Takanori Sakamoto, Bing Zhang +6
The emission mechanism and the origin and structure of magnetic fields in gamma-ray burst (GRB) jets are among the most important open questions concerning the nature of the centra…
