description: Subfamily Melinae Bonaparte, 1838. Nuovi Ann Sci. Nat., 2:111. COMMENTS: Reviewed by Long (1978) and Long and Killingley (1983). Revised by Pocock (1921 b, d, 1941a), Petter (1971), and Wozencraft (1989a), who suggested that this may not be a monophyletic group. Pocock recognized as subfamilies, and Petter as tribes, four groups: (1) Meles, Arctonyx; (2) Melogale; (3) Mydaus; and (4) Taxidea. Pocock (1920b), Long (1981), and Wozencraft (1989b) argued for the separation of Taxidea into a monotypic subfamily, Taxidiinae, which would be consistent with the phylogenetic hypotheses refered to above and which will be followed here. Petter (1971), Radinsky (1973), and Schmidt-Kittler (1981) suggested that Mydaus may be the sister group to Mephitinae. Its placement in this subfamily is provisional.

description: Many galaxy clusters host Megaparsec-scale radio halos, generated by ultrarelativistic electrons in the magnetized intracluster medium. Correlations between the power of radio halos and the thermal properties of the hosting clusters were established in the last decade, including the connection between the presence of a halo and cluster mergers. The X-ray luminosity and redshift limited Extended GMRT Radio Halo Survey provides a rich and unique dataset for statistical studies of the halos. We uniformly analyze the radio and X-ray data for the GMRT cluster sample, and use the new Planck SZ catalog, to revisit the correlations between the power of halos and the thermal properties of galaxy clusters. We find that the radio power of halos at 1.4 GHz scales with the cluster X-ray (0.1--2.4 keV) luminosity computed within R_500 as P_1.4 L_500^2.0. Our bigger and more homogenous sample confirms that the X-ray luminous (L_500 > 5x10^44 erg/s) clusters branch into two populations --- radio halos lie on the correlation, while clusters with upper limits to radio-halo emission are well below that correlation. This bimodality remains if we excise cool cores from the X-ray luminosities. Correlating with Planck data, we find that P_1.4 scales with the cluster integrated SZ signal within R_500 as P_1.4 Y_500^2.1, in line with previous findings. However, contrary to previous studies that were limited by incompleteness and small sample size, we find that the "SZ-luminous" Y_500 > 6x10^-5 Mpc^2 clusters show a bimodal behavior similar to that in the radio-X-ray diagram. Bimodality of both correlations can be traced to clusters dynamics, with radio halos found exclusively in merging clusters. These results confirm the key role of mergers for the origin of giant radio halos, suggesting that they trigger the relativistic particle acceleration.

description: Excited state spectra are calculated using lattice QCD for baryons that can be formed from $u$, $d$ and $s$ quarks, namely the $N$, $Δ$, $Λ$, $Σ$, $Ξ$ and $Ω$ families of baryons. Baryonic operators are constructed from continuum operators that transform as irreducible representations of SU(3)$_F$ symmetry for flavor, SU(4) symmetry for Dirac spins of quarks and O(3) symmetry for orbital angular momenta. Covariant derivatives are used to realize orbital angular momenta. Using the operators, we calculate matrices of correlation functions in order to extract excited states. The resulting lattice spectra have bands of baryonic states with well-defined total spins up to $J=7/2$. Each state can be assigned a dominant flavor symmetry and the counting of states of each flavor and spin reflects $SU(6) \times O(3)$ symmetry for the lowest negative-parity and positive-parity bands. States with strong hybrid content are identified through the dominance of chromo-magnetic operators.

Dynamical Dark Matter and the Positron Excess in Light of AMS

description: The AMS-02 experiment has recently released data which confirms a rise in the cosmic-ray positron fraction as a function of energy up to approximately 350 GeV. Over the past decade, attempts to interpret this positron excess in terms of dark-matter decays have become increasingly complex and have led to a number of general expectations about the decaying dark-matter particles: such particles cannot undergo simple two-body decays to leptons, for example, and they must have rather heavy TeV-scale masses. In this paper, by contrast, we show that Dynamical Dark Matter (DDM) can not only match existing AMS-02 data on the positron excess, but also accomplish this feat with significantly lighter dark-matter constituents undergoing simple two-body decays to leptons. Moreover, we demonstrate that this can be done without running afoul of numerous other competing constraints from FERMI and Planck on decaying dark matter. Finally, we demonstrate that the Dynamical Dark Matter framework makes a fairly robust prediction that the positron fraction should level off and then remain roughly constant out to approximately 1 TeV, without experiencing any sharp downturns. Indeed, if we interpret the positron excess in terms of decaying dark matter, we find that the existence of a plateau in the positron fraction at energies less than 1 TeV may be taken as a "smoking gun" of Dynamical Dark Matter.

description: In powerful radio-quiet active galactic nuclei (AGN), black holes heavier than one billion solar masses form at a redshift ~1.5-2. Supermassive black holes in jetted radio-loud AGN seems to form earlier, at a redshift close to 4. The ratio of active radio-loud to radio-quiet AGN hosting heavy black holes is therefore a rather a strong function of redshift. We report on some recent evidence supporting this conclusion, gathered from the Burst Alert Telescope (BAT, onboard Swift) and by the Large Area Telescope (LAT, onboard Fermi). We suggest that the more frequent occurrence of relativistic jets in the most massive black holes at high redshifts, compared to later times, could be due to the average black hole spin being greater in the distant past, or else to the jet helping a fast accretion rate (or some combination of the two scenarios). We emphasize that the large total accretion efficiency of rapidly spinning black holes inhibits a fast growth, unless a large fraction of the available gravitational energy of the accreted mass is not converted into radiation, but used to form and maintain a powerful jet.

description: The world is currently going through an ‘Energy Transition’ and it is changing how our economies, culture and society operate. The research presented in this thesis emanates from large scale changes and is investigated through three distinct research papers, with separate but interlinked themes. Research paper 1 (Chapter 2) profiles households that have adopted of micro renewable energy systems (micro-RES) and examines whether micro-RES installations have impacted energy consumption based on data from the Irish Household Budget Survey. Our findings indicate that some revision of energy policy is needed, as the presence of micro-RES doesn’t affect total energy usage. Research paper 2 (Chapter 3) investigates how the success of solar PV has given rise to a positive feedback cycle in the residential electricity market, whereby increased customer adoption results in reduced demand from utility providers. This leads to price increases and further incentivises customers to adopt solar PV. Empirical findings indicate strong support for the idea of a positive feedback cycle using data from the UK, Australian and Irish Markets. This reinforces the need for stakeholders to consider this issue in framing future energy policies to ensure that the adoption of solar PV is supported in a sustainable way, while not punishing non-adopters with higher electricity rates. Research paper 3 (Chapter 4) employs a new multidimensional measurement to gauge the extent of fuel poverty in the USA. For the three coldest regions in the USA, we find that 12% (New England), 13% (East North Central) & 9% (West North Central) of households are fuel poor. Empirical findings show that the odds of being fuel poor are higher for households with elderly people and children present. These results have useful implications for policy formation and targeting appropriate supports to address this issue.

description: We present a new determination of the UV galaxy luminosity function (LF) at redshift z ~ 7 and z ~ 8, and a first estimate at z ~ 9. An accurate determination of the form and evolution of the LF at high z is crucial for improving our knowledge of early galaxy evolution and cosmic reionization. Our analysis exploits fully the new, deepest WFC3/IR imaging from our HST UDF12 campaign, and includes a new, consistent analysis of all appropriate, shallower/wider-area HST data. Our new measurement of the evolving LF at z ~ 7-8 is based on a final catalogue of ~600 galaxies, and involves a step-wise maximum likelihood determination based on the redshift probability distribution for each object; this makes full use of the 11-band imaging now available in the HUDF, including the new UDF12 F140W data, and the deep Spitzer IRAC imaging. The final result is a determination of the z ~ 7 LF extending down to M_UV = -16.75, and the z ~ 8 LF down to M_UV = -17.00. Fitting a Schechter function, we find M* = -19.90 (+0.23/-0.28), log phi* = -2.96 (+0.18/-0.23), and a faint-end slope alpha=-1.90 (+0.14/-0.15) at z~7, and M* = -20.12 (+0.37/-0.48), log phi* = -3.35 (+0.28/-0.47), alpha=-2.02 (+0.22/-0.23) at z~8. These results strengthen suggestions that the evolution at z > 7 is more akin to `density evolution' than the apparent `luminosity evolution' seen at z ~ 5-7. We also provide the first meaningful information on the LF at z ~ 9, explore alternative extrapolations to higher z, and consider the implications for the evolution of UV luminosity density. Finally, we provide catalogues (including z_phot, M_UV and all photometry) for the 100 most robust z~6.5-11.9 galaxies in the HUDF used in this analysis. We discuss our results in the context of earlier work and the results of an independent analysis of the UDF12 data based on colour-colour selection (Schenker et al. 2013).

description: We systematically investigate the dependence of the temperature of cold cesium atoms of polarization gradient cooling (PGC) in optical molasses on experimental parameters, which contain changing modes of cooling laser, PGC interaction time, cooling laser frequency and its intensity. The SR mode of cooling laser, that means the cooling laser frequency is changed with step mode and cooling laser intensity is changed with ramp mode, is found to be the best for PGC comparing with other SS, RS, and RR modes. We introduce a statistical explanation and an exponential decay function to explain the variation of cold atomic temperature on time. The heating effect is observed when the cooling laser intensity is lower than the saturation intensity of cold atoms. After optimization, the lowest temperature of cold cesium atoms is observed to be about 4uK with the number of 2x10^9, a density of 1x10^11/cm^3 and the phase space density of 4.4x10^(-5). The optimization process and analysis of controllable experimental parameters are also meaningful for other cold atomic systems.

These identities relate (N+1)-point correlation functions with a soft external Goldstone to N-point functions. These relations have direct implications for the recently proposed conformal mechanism for generating density perturbations in the early universe. We study the observational consequences, in particular a novel one-loop contribution to the four-point function, relevant for the stochastic scale-dependent bias and CMB mu-distortion.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider an SU(3)'_c\times SU(2)'_L\times U(1)'_Y mirror sector where the field content and dimensionless couplings are a copy of the SU(3)_c\times SU(2)_L\times U(1)_Y ordinary sector. Our model also contains three gauge-singlet fermions with heavy Majorana masses and an [SU(2)_L\times SU(2)'_L]-bidoublet Higgs scalar with seesaw-suppressed vacuum expectation value. The mirror sterile neutrino masses will have a form of canonical seesaw while the ordinary active neutrino masses will have a form of double and linear seesaw. In this canonical and double-linear seesaw scenario, we can expect one sterile neutrino at the eV scale and the other two above the MeV scale to fit the cosmological and short baseline neutrino oscillation data. Associated with the SU(2)_L and SU(2)'_L sphaleron processes, the decays of the fermion singlets can simultaneously generate a lepton asymmetry in the [SU(2)_L]-doublet leptons and an equal lepton asymmetry in the [SU(2)'_L]-doublet leptons to explain the existence of baryonic and dark matter. The lightest mirror baryon then should have a determined mass around 5 GeV to account for the dark matter relic density. The U(1) kinetic mixing can open a window for dark matter direct detection.

description: Correctly assessing a scientist's past research impact and potential for future impact is key in recruitment decisions and other evaluation processes. While a candidate's future impact is the main concern for these decisions, most measures only quantify the impact of previous work. Recently, it has been argued that linear regression models are capable of predicting a scientist's future impact. By applying that future impact model to 762 careers drawn from three disciplines: physics, biology, and mathematics, we identify a number of subtle, but critical, flaws in current models. Specifically, cumulative non-decreasing measures like the h-index contain intrinsic autocorrelation, resulting in significant overestimation of their "predictive power". Moreover, the predictive power of these models depend heavily upon scientists' career age, producing least accurate estimates for young researchers. Our results place in doubt the suitability of such models, and indicate further investigation is required before they can be used in recruiting decisions.

description: Whiplash Associated Disorder (WAD) cases millions of injuries and billions of dollars in litigation and medical cost. The purpose of this study was to determine if any relationship existed between certain occupant and vehicular constants and the onset and severity of WAD. One hundred subjects involved in low-speed collisions were selected from an active database. Fifty-nine subjects were females and 70% of the subjects were drivers. A discriminant function analysis was performed, with occupant position and duration as the only variables that had significant discriminating power. However, eighty-four percent of the subjects experienced 100millisecond accelerations and 70% were drivers. Therefore, it was concluded that there needs to be further fine tuning to distinguish between the various levels of WAD and there were no significant gender or body composition differences that preclude a person to suffering WAD.

description: Preface: The main goal of this work is to give an introductory account of sieve methods that would be understandable with only a slight knowledge of analytic number theory. These notes are based to a large extent on lectures on sieve methods given by Professor Van Lint and the author in a number theory seminar during the 1970-71 academic year, but rather extensive changes have been made in both the content and the presentation.

description: Bibliometric indicators can be determined by comparing specific citation records with the percentiles of a reference set. However, there exists an ambiguity in the computation of percentiles because usually a significant number of papers with the same citation count are found at the border between percentile rank classes. The present case study of the citations to the journal Europhysics Letters (EPL) in comparison with all physics papers from the Web of Science shows the deviations which occur due to the different ways of treating the tied papers in the evaluation of the percentage of highly cited publications. A strong bias can occur, if the papers tied at the threshold number of citations are all considered as highly cited or all considered as not highly cited.

description: We study free topological groups defined over uniform spaces in some subclasses of the class NA of non-archimedean groups. Our descriptions of the corresponding topologies show that for metrizable uniformities the corresponding free balanced, free abelian and free Boolean NA groups are also metrizable. Graev type ultra-metrics determine the corresponding free topologies. Such results are in a striking contrast with free balanced and free abelian topological groups cases (in standard varieties). Another contrasting advantage is that the induced topological group actions on free abelian NA groups frequently remain continuous. One of the main applications is: any epimorphism in the category NA must be dense. Moreover, the same methods improve the following result of T.H. Fay : the inclusion of a proper open subgroup H into G is not an epimorphism in the category of all Hausdorff topological groups. A key tool in the proofs is Pestov's test of epimorphisms. Our results provide a convenient way to produce surjectively universal NA abelian and balanced groups. In particular, we unify and strengthen some recent results of Gao and Gao-Xuan as well as classical results about profinite groups which go back to Iwasawa and Gildenhuys-Lim.

description: We consider the evolution of primordial magnetic fields generated during cosmological, electroweak or QCD, phase transitions. We assume that the magnetic field generation can be described as an injection of magnetic energy to cosmological plasma at a given scale determined by the moment of magnetic field generation. A high Reynolds number ensures strong coupling between magnetic field and fluid motions. The subsequent evolution of the magnetic field is governed by decaying hydromagnetic turbulence. Both our numerical simulations and a phenomenological description allow us to recover "universal" laws for the decay of magnetic energy and the growth of magnetic correlation length in the turbulent (low viscosity) regime. In particular, we show that during the radiation dominated epoch, energy and correlation length of non-helical magnetic fields scale as conformal time to the powers -1/2 and +1/2, respectively. For helical magnetic fields, energy and correlation length scale as conformal time to the powers -1/3 and +2/3, respectively. The universal decay law of the magnetic field implies that the strength of magnetic field generated during the QCD phase transition could reach $\sim 10^{-9}$\,G with the present day correlation length $\sim 50$ kpc. The fields generated at the electroweak phase transition could be as strong as $\sim 10^{-10}$ G with correlation lengths reaching $\sim 0.3$\,kpc. These values of the magnetic fields are consistent with the lower bounds of the extragalactic magnetic fields.

description: We describe a region of the No-Scale F-SU(5) supersymmetric model with TeV-scale vector-like matter multiplets that is potentially opaque to LHC observations based upon top quark reconstruction. Possessing a 100% on-shell branching fraction for gluino to light stop decays, the gluino-light stop mass splitting in F-SU(5) lies very close to the top quark rest mass in the region 810 (650)

Geoffroy Saint-Hilaire, 1831. SYNONYMS: Helictis Gray, 1831; Nesictis Thomas, 1922. COMMENTS: There is uncertainty as to the the total number of species in this genus. Most recent authors tend to consider everetii and/ or orientalis as conspecific with personata; however, Pocock (1941a), Everts (1968), Long (1978, 1981), and Long and Killingley (1983) supported the recognition of these populations as distinct. As Long and Killingley pointed out, there is no published information to refute Pocock's (1941a) revision.

description: We study one-loop photon (Pi) and neutrino (Sigma) self-energies in a U(1) covariant gauge-theory on d-dimensional noncommutative spaces determined by a antisymmetric-constant tensor theta^{mu nu}. For the general fermion-photon (S_f) and photon self-interaction (S_g) the closed form results reveal self-energies besetting with all kind of pathological terms: the UV divergence, the quadratic UV/IR mixing terms as well as a logarithmic IR divergent term of the type ln(mu^2(theta p)^2). In addition, the photon-loop produces new tensor structures satisfying transversality condition by themselves. We show that the photon self-energy in four-dimensional Euclidean spacetime can be reduced to two finite terms by imposing a specific full rank of theta^{mu nu} and setting deformation parameters (kappa_f,kappa_g)=(0,3). In this case the neutrino two-point function vanishes. Thus for a specific point (0,3) in the parameter-space (kappa_f,kappa_g), a covariant theta-exact approach is able to produce a divergence-free result for one-loop quantum corrections, having also well-defined both the commutative limit as well as the pointlike limit of an extended object. While in two-dimensional space the photon self-energy is finite for arbitrary (kappa_f,kappa_g) combinations, the neutrino self-energy still contains an superficial IR divergence.

Isothermal distributions in MONDian gravity as a simple unifying explanation for the ubiquitous $ρ\propto r^{-3}$ density profiles in tenuous stellar halos

description: That the stellar halo of the Milky Way has a density profile which to first approximation satisfies $ρ\propto r^{-3}$ has been known for a long time. More recently, it has become clear that M31 also has such an extended stellar halo, which approximately follows the same radial scaling. Studies of distant galaxies have revealed the same phenomenology. Also, we now know that the density profiles of the globular cluster systems of our Galaxy and Andromeda to first approximation follow $ρ\propto r^{-3}$, $Σ\propto R^{-2}$ in projection. Recently, diffuse populations of stars have been detected spherically surrounding a number of Galactic globular clusters, extending much beyond the Newtonian tidal radii, often without showing any evidence of tidal features. Within the standard Newtonian and GR scenario, numerous and diverse particular explanations have been suggested, individually tailored to each of the different classes of systems described above. Here we show that in a MONDian gravity scenario, any isothermal tenuous halo of tracer particles forming a small perturbation surrounding a spherically symmetric mass distribution, will have an equilibrium configuration which to first approximation satisfies a $ρ\propto r^{-3}$ scaling.

Some investigations of heterogeneous flow in a rocket nozzle
Creators: name: Seymour, Ernest Richard
Publisher: name: California Institute of Technology
Year: 1962
Subjects: Aeronautics

description: In the heterogeneous flow of finely divided particles and gas in a rocket nozzle, the assumptions that the flow enters the nozzle with no lags, that the radiative transport of energy between particles is negligible, and that there are no temperature gradients within the particles, are commonly made. In this paper, each of these assumptions is investigated in detail, and they are shown to be reasonable for typical rocket nozzles.
The buckling of thin walled circular cylindrical shells under combined axial compression and bending
Creators: name: Stuart, Floyd R.
Publisher: name: California Institute of Technology
Year: 1963
Subjects: Aeronautics

description: An experimental investigation of the interaction of combined axial compression and bending stresses on the buckling of cylindrical shells of similar geometry was carried out.

The shells tested were manufactured by a copper electro-forming process. This method of fabrication produced thin shells to close geometric tolerances without the usual seams.

A total of 16 buckling tests were conducted. The resulting experimental interaction curve indicates that the critical buckling stress increases with increased bending moments.
Low thrust trajectories using the two variable asymptotic expansion method
Creators: name: Stavro, William C.
Publisher: name: California Institute of Technology
Year: 1969
Subjects: Aeronautics

description: An approximate analytic solution is derived in this thesis for the variables which describe a heliocentric low-thrust trajectory.  The two-variable asymptotic expansion procedure is used.  It is assumed that the thrust acceleration varies as the inverse of the distance to the central body raised to an arbitrary power α.  Thus the value of α = 1.4 will represent a solar-electric propulsion system, and the value of α = 0 will represent a nuclear-electric system.  It is also assumed that the mass of the spacecraft remains constant and that the direction of the thrust vector is arbitrary but remains constant.  The results are  compared to numerical integrations and to other integrating low-thrust programs.

description: A soft X-ray, beam-splitting, multilayer optic has been developed for the Bragg Reflection Polarimeter (BRP) on the NASA Gravity and Extreme Magnetism Small Explorer Mission (GEMS). The optic is designed to reflect 0.5 keV X-rays through a 90 degree angle to the BRP detector, and transmit 2-10 keV X-rays to the primary polarimeter. The transmission requirement prevents the use of a thick substrate, so a 2 micron thick polyimide membrane was used. Atomic force microscopy has shown the membrane to possess high spatial frequency roughness less than 0.2 nm rms, permitting adequate X-ray reflectance. A multilayer thin film was especially developed and deposited via magnetron sputtering with reflectance and transmission properties that satisfy the BRP requirements and with near-zero stress. Reflectance and transmission measurements of BRP prototype elements closely match theoretical predictions, both before and after rigorous environmental testing.
