Suppression of the shear viscosity near the critical temperature in hot QCD

description: We consider QCD near but above critical temperature Tc. The pressure, susceptibilities and the renormalized Polyakov loop -- which is an order parameter for the deconfining phase transition -- dramatically change up to temperatures a few times Tc. We refer to this region as a "semi"-QGP, where partial confinement plays important role. We show that the shear viscosity ,eta, is suppressed by two powers of the Polyakov loop. This suggests that eta/T^3 decreases markedly as QCD cools down to temperatures near Tc. We also show a ratio of the viscosity to the entropy becomes small near Tc.

Una materia oscura meno esotica?
Creators: Corrado Ruscica
Publisher: name: Media Inaf
Year: 2015

Uno studio su Physical Review Letters suggerisce che la materia oscura sarebbe simile alle particelle subatomiche chiamate pioni. La nuova ipotesi, basata sull'esistenza di particelle denominate SIMP, risolverebbe alcune discrepanze tra dati e simulazioni numeriche e avrebbe profonde implicazioni sui metodi di ricerca dei prossimi esperimenti

description: Magnetic refrigeration at room temperature is of great interest due to a long-term goal of making refrigeration more energy-efficient, less noisy and free of any environmentally hostile materials. A refrigerator utilizing an active magnetic regenerator (AMR) is based on the magnetocaloric effect, which manifests itself as a temperature change in magnetic materials when subjected to a varying magnetic field. In this work we present the current state of magnetic refrigeration research at Risoe DTU with emphasis on the numerical modeling of an existing AMR test machine. A 2D numerical heat-transfer and fluid-flow model that represents the experimental setup is presented. Experimental data of both no-heat load and heat load situations are compared to the model. Moreover, results from the numerical modeling of the permanent magnet design used in the system are presented.

Synthesis of linear quantum stochastic systems via quantum feedback networks
Creators: name: Nurdin, H. I.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Recent theoretical and experimental investigations of coherent feedback control, the feedback control of a quantum system with another quantum system, has raised the important problem of how to synthesize a class of quantum systems, called the class of linear quantum stochastic systems, from basic quantum optical components and devices in a systematic way. The synthesis theory sought in this case can be naturally viewed as a quantum analogue of linear electrical network synthesis theory and as such has potential for applications beyond the realization of coherent feedback controllers. In earlier work, Nurdin, James and Doherty have established that an arbitrary linear quantum stochastic system can be realized as a cascade connection of simpler one degree of freedom quantum harmonic oscillators, together with a direct interaction Hamiltonian which is bilinear in the canonical operators of the oscillators. However, from an experimental perspective and based on current methods and technologies, direct interaction Hamiltonians are challenging to implement for systems with more than just a few degrees of freedom. In order to facilitate more tractable physical realizations of these systems, this paper develops a new synthesis algorithm for linear quantum stochastic systems that relies solely on field-mediated interactions, including in implementation of the direct interaction Hamiltonian. Explicit synthesis examples are provided to illustrate the realization of two degrees of freedom linear quantum stochastic systems using the new algorithm.

The social casework approach to marital counselling : an exploratory analysis of some characteristic Family Service Agency Cases, Vancouver, 1957
Creators: name: Wharf, Brian Worth Heseltine
Publisher: name: University of British Columbia
Year: 2012

description: Social workers have been interested for many years in the problems of adjustment that occur in marriage, and have attempted to assist those families grappling with marital difficulties. In particular the Family Service Agency of this and other communities has concerned itself with marital discord, and through study has tried to broaden its knowledge, and refine its skills. This study is a part of the re-evaluation that is constantly underway. This study is an exploratory one. It is concerned with the strengths and the limitations of the social casework approach to marital counselling. The six cases examined are difficult ones containing problems of a serious nature. The primary reason for their selection was that they revealed the casework process in some detail. The cases have been summarized, and the casework process closely examined. On the basis of the analyses it was found that ego supportive casework, the observance of the social work principles of self-determination, individuality, objectivity and the non-judgmental attitude, and the use of community resources are extremely helpful to families experiencing marital problems. In addition, the ability of the caseworker to grasp the total functioning of the client in his family and social situation is a positive aspect of the casework approach. The chief weakness of the casework approach as it has been evolved to the present time is the policy of routinely assigning one caseworker to help both partners. When the partners are dependent and immature people they are unable to share a deep, therapeutic relationship with the same caseworker. This study supports a proposal made by Mr. Sidney Berkowitz some years ago. Mr. Berkowitz claimed that the caseworker should decide early in the contact whether serious conflicts or mild disturbance was involved, and that two caseworkers should be assigned in the former instance. Other weaknesses in the casework approach resulted from the caseworker's lack of diagnostic thinking and planning, and from their failure to observe the social work principles. The caseworkers also did not seem to realize the harmful effects of marital discord upon the children, and in only one case was direct casework help extended to a child.

Angular Momentum Transport In Solar-Type Stars: Testing the Timescale For Core-Envelope Coupling

description: We critically examine the constraints on internal angular momentum transport which can be inferred from the spin down of open cluster stars. The rotation distribution inferred from rotation velocities and periods are consistent for larger and more recent samples, but smaller samples of rotation periods appear biased relative to vsini studies. We therefore focus on whether the rotation period distributions observed in star forming regions can be evolved into the observed ones in the Pleiades, NGC2516, M34, M35, M37, and M50 with plausible assumptions about star-disk coupling and angular momentum loss from magnetized solar-like winds. Solid body models are consistent with the data for low mass fully convective stars but highly inconsistent for higher mass stars where the surface convection zone can decouple for angular momentum purposes from the radiative interior. The Tayler-Spruit magnetic angular momentum transport mechanism, commonly employed in models of high mass stars, predicts solid-body rotation on extremely short timescales and is therefore unlikely to operate in solar-type pre-MS and MS stars at the predicted rate. Models with core-envelope decoupling can explain the spin down of 1.0 and 0.8 solar mass slow rotators with characteristic coupling timescales of 55+-25 Myr and 175+-25 Myr respectively. The upper envelope of the rotation distribution is more strongly coupled than the lower envelope of the rotation distribution, in accord with theoretical predictions that the angular momentum transport timescale should be shorter for more rapidly rotating stars. Constraints imposed by the solar rotation curve are also discussed (Abridged)

description: Recent panoramic observations of the dominant spiral galaxies of the Local Group have revolutionized our view of how these galaxies assemble their mass. However, it remains completely unclear whether the properties of the outer regions of the Local Group large spirals are typical. Here, we present the first panoramic view of a spiral galaxy beyond the Local Group, based on the largest, contiguous, ground-based imaging survey to date resolving the stellar halo of the nearest prime analogue of the Milky Way, NGC 891 (D~10 Mpc). The low surface brightness outskirts of this galaxy are populated by multiple, coherent, and vast substructures over the 90kpc * 90kpc extent of the survey. These include a giant stream, the first to be resolved into stars beyond the Local Group using ground-based facilities, that loops around the parent galaxy up to distances of ~50kpc. The bulge and the disk of the galaxy are found to be surrounded by a previously undetected large, flat and thick cocoon-like stellar structure at vertical and radial distances of up to ~15kpc and ~40kpc respectively.

Studies on the action of streptomycin
Creators: name: Blair, A. Huntley
Publisher: name: University of British Columbia
Year: 2012

description: The mode of action of streptomycin has been investigated with specific emphasis on the effect of the antibiotic on adaptive enzyme formation by Escherichia coli. The first phase of this study was to investigate the possibility that streptomycin interferes with the action of a metabolite required by E. coli for enzyme synthesis and growth. A resistant variant of E. coli, which exhibited partial dependence on the drug for enzyme formation, was used to test for the presence of a metabolite in other variants which did not exhibit this dependence. Subcellular fractions derived from susceptible and resistant cells were tested for the presence of a substance which would satisfy the streptomycin requirement of partially dependent organisms for enzyme induction. All attempts to demonstrate such a metabolite were unsuccessful. In the second phase of the study, the effect of streptomycin on the protein and nucleic acid content of partially dependent cells during enzyme induction was studied. By the standard techniques employed, it was shown that the antibiotic did not affect either the gross protein or nucleic acid content of the cells during the period in which the formation of a specific enzyme was demonstrated.

description: We use neutron spectroscopy to determine the nature of the magnetic excitations in superconducting BaFe$_{1.9}$Ni$_{0.1}$As$_{2}$ ($T_{c}=20$ K). Above $T_{c}$ the excitations are gapless and centered at the commensurate antiferromagnetic wave vector of the parent compound, while the intensity exhibits a sinusoidal modulation along the c-axis. As the superconducting state is entered a spin gap gradually opens, whose magnitude tracks the $T$-dependence of the superconducting gap observed by angle resolved photoemission. Both the spin gap and magnetic resonance energies are temperature \textit{and} wave vector dependent, but their ratio is the same within uncertainties. These results suggest that the spin resonance is a singlet-triplet excitation related to electron pairing and superconductivity.

description: MOG is a fully relativistic modified theory of gravity based on an action principle. The MOG field equations are exactly solvable numerically in two important cases. In the spherically symmetric, static case of a gravitating mass, the equations also admit an approximate solution that closely resembles the Reissner-Nordstrom metric. Furthermore, for weak gravitational fields, a Yukawa-type modification to the Newtonian acceleration law can be obtained, which can be used to model a range of astronomical observations. Without nonbaryonic dark matter, MOG provides good agreement with the data for galaxy rotation curves, galaxy cluster masses, and gravitational lensing, while predicting no appreciable deviation from Einstein's predictions on the scale of the solar system. Another solution of the field equations is obtained for the case of a a spatially homogeneous, isotropic cosmology. MOG predicts an accelerating universe without introducing Einstein's cosmological constant; it also predicts a CMB acoustic power spectrum and a mass power spectrum that are consistent with observations without relying on non-baryonic dark matter. Increased sensitivity in future observations or space-based experiments may be sufficient to distinguish MOG from other theories, notably the LCDM "standard model" of cosmology.

description: We present extensive photometry at ultraviolet (UV), optical, and near-infrared (NIR) wavelengths, as well as dense sampling of optical spectra, for the normal type Ia supernova (SN Ia) 2005cf. From the well-sampled light curves, we find that SN 2005cf reached a B-band maximum at 13.63+/-0.02 mag, with an observed luminosity decline rate dm_15(B) = 1.05+/-0.03 mag. The correlations between the decline rate and various color indexes, recalibrated on the basis of an expanded SN Ia sample, yielded E(B-V)_host=0.09+/-0.03 mag for SN2005cf. The UV photometry was obtained with the HST and the Swift Ultraviolet/Optical Telescope, and the results match each other to within 0.1-0.2 mag. The UV light curves show similar evolution to the broadband U, with an exception in the 2000-2500 Angstrom spectral range (corresponding to the F220W/uvm2 filters), where the light curve appears broader and much fainter than that on either side (likely owing to the intrinsic spectral evolution). Combining the UV data with the ground-based optical and NIR data, we establish the generic UV-optical-NIR bolometric light curve for SN 2005cf and derive the bolometric corrections in the absence of UV and/or NIR data. The overall spectral evolution of SN 2005cf is similar to that of a normal SN Ia, but with variety in the strength and profile of the main feature lines. The spectra at early times displayed strong, detached high-velocity (HV) features in the Ca II H&K doublet and NIR triplet. Similar HV features may exist in the SiII 6355 absorption line which evolved rapidly from a flat-bottomed feature in the earliest phase to a triangular shape one week before maximum, and may be common in other normal SNe Ia. The possible origin of the HV absorption features is briefly discussed (abridged).

description: We present numerical calculation of the evolution of a background space-time metric and sub-horizon matter density perturbations in viable $f(R)$ gravity models of present dark energy and cosmic acceleration. We found that viable models generically exhibit recent crossing of the phantom boundary $w_{DE}=-1$. Moreover, as a consequence of the anomalous growth of density perturbations during the end of the matter-dominated stage, their growth index evolves non-monotonically with time and may even become negative.

Nella ricerca di mondi alieni c'è un altro parametro da considerare per le condizioni di abitabilità: la sua composizione chimica. E' quanto emerge da uno studio apparso su Nature Geoscience secondo cui la formazione della tettonica a placche, del vulcanismo e dell’emissione di anidride carbonica rappresentano le principali variabili che possono condizionare il clima e quindi l'abitabilità di un pianeta

description: We propose that the leptonic cosmic ray signals seen by PAMELA and ATIC result from the annihilation or decay of dark matter particles via states of a leptonic Higgs doublet to $τ$ leptons, linking cosmic ray signals of dark matter to LHC signals of the Higgs sector. The states of the leptonic Higgs doublet are lighter than about 200 GeV, yielding large $\barτ τ$ and $\barτ τ\barτ τ$ event rates at the LHC. Simple models are given for the dark matter particle and its interactions with the leptonic Higgs, for cosmic ray signals arising from both annihilations and decays in the galactic halo. For the case of annihilations, cosmic photon and neutrino signals are on the verge of discovery.

Un gruppo compatto di galassie, molte delle quali attive, è stato individuato da un team di ricercatori guidato da Alessandra De Rosa dell'INAF. Le proprietà dell'oggetto celeste, denominato SDSS J0959+1259, lo rendono un promettente laboratorio per studiare fenomeni di interazione tra galassie e la formazione dei buchi neri supermassivi
Vector and Axial Currents in Wilson Chiral Perturbation Theory

description: We reconsider the construction of the vector and axial-vector currents in Wilson Chiral Perturbation Theory (WChPT), the low-energy effective theory for lattice QCD with Wilson fermions. We discuss in detail the finite renormalization of the currents that has to be taken into account in order to properly match the currents. We explicitly show that imposing the chiral Ward identities on the currents does, in general, affect the axial-vector current at O(a). As an application of our results we compute the pion decay constant to one loop in the two flavor theory. Our result differs from previously published ones.

Casimir Effect for a Semitransparent Wedge and an Annular Piston

description: We consider the Casimir energy due to a massless scalar field in a geometry of an infinite wedge closed by a Dirichlet circular cylinder, where the wedge is formed by $δ$-function potentials, so-called semitransparent boundaries. A finite expression for the Casimir energy corresponding to the arc and the presence of both semitransparent potentials is obtained, from which the torque on the sidewalls can be derived. The most interesting part of the calculation is the nontrivial nature of the angular mode functions. Numerical results are obtained which are closely analogous to those recently found for a magnetodielectric wedge, with the same speed of light on both sides of the wedge boundaries. Alternative methods are developed for annular regions with radial semitransparent potentials, based on reduced Green's functions for the angular dependence, which allows calculations using the multiple-scattering formalism. Numerical results corresponding to the torque on the radial plates are likewise computed, which generalize those for the wedge geometry. Generally useful formulas for calculating Casimir energies in separable geometries are derived.
