description: We study the Einstein-Chern-Simons gravity coupled to Yang-Mills-Higgs theory in three dimensional Euclidean space with cosmological constant. The classical equations reduce to Bogomol'nyi type first order equations in curved space. There are BPS type gauge theory instanton (monopole) solutions of finite action in a gravitational instanton which itself has a finite action. We also discuss gauge theory instantons in the vacuum (zero action) AdS space. In addition we point out to some exact solutions which are singular.

description: Levels of five heavy metals namely, cadmium, cobalt, iron, lead, and zinc were determined in tissues (roots, leaves and stems) of Azadirachta indica collected at different spots in Akungba-Akoko, (Nigeria). Transfer coefficients of the elements into the plant tissues were also determined with a view to quantifying the differences in bioavailability to the plant species. The tissues were acid-digested and analyzed by flame atomic absorption spectrophotometry. The levels (ppm) of heavy metals recorded in the roots, leaves and stems of the plant respectively ranged: Cd (0.14 – 0.34, 0.09 – 0.20, 0.09 – 0.33); Co (4.01 – 5.48, 3.22 – 5.14, 3.84 – 5.40); Fe (82.27 – 137.98, 49.20 – 160.10, 58.33 – 116.62); Pb (0.50 – 0.57, 0.33 – 0.97, 0.28 – 0.48) and Zn (52.07 – 149.94, 52.01 – 113.73, 49.58 – 127.05). Fe has highest concentration while Cd has lowest concentration in all tissues analyzed. The stems of the plant showed least bioaccumulation of most metals studied and hence most suitable for medicinal purpose. The order of bioaccumulation by the leaves, stem barks, and roots of Azadirachta indica followed the sequence Pb < Cd < Zn < Fe < Co. Since metal uptake from plants is a major component of human exposure via the food chain, vegetative parts of Azadirachta indica used for therapeutic purposes should be collected far away from highways to reduce or possibly eliminate health hazards associated with the ingestion of heavy metals.

description: An experimental study of current-induced magnetization reversal of the Ru/Co/Ru and Ru/Co/Ru/W structures was carried out. In the considered structures, due to the small value of the coercive force comparable in magnitude to the Oersted field and the SOT effect field, magnetization reversal is carried out by moving a domain wall parallel to the direction of current injection. For such a case, a new method for estimating the effective field of SOT based on the analysis of the domain wall position taking into account the distribution of the Oersted field was proposed. This method allowed determining the effective longitudinal field and the efficiency of SOT equal 0.03 in the quasi-symmetric Ru/Co/Ru structure. It was found that adding the W capping layer enhances the SOT effect by 5 times.

description: Contact friction is a key influence factor for the shearing behaviour of granular media. In the discrete element method (DEM) contact friction is usually modelled with Coulomb's law assuming a constant interparticle friction coefficient. From tribology it is known that friction is influenced by several factors, e.g., temperature, normal stress, surface condition, etc. None of these influences can be modelled with the constant interparticle friction coefficient from Coulomb's law. For a given granular material (particle shape distribution), the usage of constant interparticle friction in DEM models generally results in constant bulk friction coefficients in the simulation of direct shear tests. While this is frequently seen in experiments with equi-sized spherical particles, papers exist in literature which report a stress dependency of bulk friction for non-spherical particles of certain materials. In this work, a stress dependency of bulk friction is obtained by introducing a model for stress dependent interparticle friction in DEM simulations. For validation experimental results of direct shear tests conducted on single or paired glass beads are used. While the bulk friction of paired spheres clearly decreases with increasing normal stress, it is nearly constant for single spheres. DEM simulations with the stress dependent interparticle friction are in good accordance with the experimental results of both single and paired spheres. A comparison with simulations, using constant interparticle friction, clearly shows the advantage of the proposed model.

description: The incoherent dynamic structure factor of ortho-terphenyl has been measured by neutron time-of-flight and backscattering technique in the pressure range from 0.1 MPa to 240 MPa for temperatures between 301 K and 335 K. Tagged-particle correlations in the compressed liquid decay in two steps. The alpha-relaxation lineshape is independent of pressure, and the relaxation time proportional to viscosity. A kink in the amplitude f_Q(P) reveals the onset of beta relaxation. The beta-relaxation regime can be described by the mode-coupling scaling function; amplitudes and time scales allow a consistent determination of the critical pressure P_c(T). alpha and beta relaxation depend in the same way on the thermodynamic state; close to the mode-coupling cross-over, this dependence can be parametrised by an effective coupling Gamma ~ n*T**{-1/4}.

Luminosity versus Rotation in a Supermassive Star

description: We determine the effect of rotation on the luminosity of supermassive stars. We apply the Roche model to calculate analytically the emitted radiation from a uniformly rotating, radiation-dominated supermassive configuration. We find that the luminosity at maximum rotation, when mass at the equator orbits at the Kepler period, is reduced by ~36% below the usual Eddington luminosity from the corresponding nonrotating star. A supermassive star is believed to evolve in a quasistationary manner along such a maximally rotating ``mass-shedding'' sequence before reaching the point of dynamical instability; hence this reduced luminosity determines the evolutionary timescale. Our result therefore implies that the lifetime of a supermassive star prior to dynamical collapse is ~56% longer than the value typically estimated by employing the usual Eddington luminosity.

The complex behaviour of the system originates from the competition between the crystalline electric field and the Ruderman-Kittel-Kasuya-Yosida interaction, whose effective form is obtained. No essential influence of superconductivity has to be invoked to understand the magnetic phase diagram of this material.

Year: 1998
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We investigate the thermally activated magnetization switching of small ferromagnetic particles driven by an external magnetic field. For low uniaxial anisotropy the spins can be expected to rotate coherently, while for sufficient large anisotropy they should behave Ising-like, i.e., the switching should then be due to nucleation. We study this crossover from coherent rotation to nucleation for the classical three-dimensional Heisenberg model with a finite anisotropy. The crossover is influenced by the size of the particle, the strength of the driving magnetic field, and the anisotropy. We discuss the relevant energy barriers which have to be overcome during the switching, and find theoretical arguments which yield the energetically favorable reversal mechanisms for given values of the quantities above. The results are confirmed by Monte Carlo simulations of Heisenberg and Ising models.

description: We investigate an interacting two-fluid model in a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) Universe, when the energy transfer between these two dark components is produced by a factorisable nonlinear sign-changeable interaction depending linearly on the energy density and quadratically on the deceleration parameter. We solve the source equation and obtain the effective energy densities of the dark sector and their components. We show that the effective equation of state of the dark sector includes some of the several kind of Chaplygin gas equations of state as well as a generalization of the polytropic equation of state. We use bayesian statistics methods to constrain free parameters in the models during its most recent evolution considering supernovae type Ia and measurements of the Hubble expansion rate. The resulting constraints provide new information on sign-changeable interactions, its equivalences and compatibility with previous models and novel late time universe dynamics.

It is shown, without any gauge fixing, that the Hamiltonian has the generalized Dirac-ADM form, and constraints satisfy all the consistency requirements. The set of constraints involves some extra first class constraints, which are used to find additional gauge symmetries and clarify the gauge structure of the theory.

description: Because of the non-uniformity of the electric power CPS network and the dynamic nature of the risk propagation process, it is difficult to quantify the critical point of a cyber risk explosion. From the perspective of the dependency network, this paper proposes a method for quantitative evaluation of the risk propagation threshold of power CPS networks based on the percolation theory. First, the power CPS network is abstracted as a dual-layered network-directed unweighted graph according to topology correlation and coupling logic, and the asymmetrical balls-into-bins allocation method is used to establish a "one-to-many" and "partially coupled" non-uniform power CPS characterization model. Then, considering the directionality between the cyber layer and the physical layer link, the probability of percolation flow is introduced to establish the propagation dynamic equations for the internal coupling relationship of each layer. Finally, the risk propagation threshold is numerically quantified by defining the survival function of power CPS network nodes, and the validity of the proposed method is verified by the IEEE 30-bus system and 150-node Barabsi-Albert model.

description: Maternal mortality is a major public health challenge faced by women worldwide especially in   developing countries like Nigeria. This study set out to examine the non-obstetrics factors associated with maternal mortality in Gombe metropolitan area of Gombe state. The study aims at identifying harmful cultural practices which are associated with maternal mortality in Gombe Metropolitan. Various literatures were revealed in accordance’s with the research objectives and the study adopted liberal feminist as the theoretical framework. A multistage sampling technique was adopted to draw a sample of 310 respondents. Questionnaire and interview were used as instrument of data collection. The research adopted both primary and secondary data in investigation. The data collected were analyzed using statistical package for social sciences (SPSS version 16.0) and presented using frequency, percentage, cross tabulation and chi square. Qualitative data using quotation were used to support the quantitative data. The study tested hypotheses to determine relationship between variables; the first hypotheses revealed that cultural practices such as food taboo, use of traditional herbs and female genital mutilation (FGM) are significant determinants of maternal mortality. The second hypothesis showed that use of traditional birth attendants is significant determinant of maternal mortality which is influenced by factors such as income and level of education. The findings of the study reveal that maternal mortality is influenced by social, economic and cultural factors. Therefore, the study recommends that in addressing the problem of maternal mortality there is need for creating awareness on the impact of cultural practices on maternal health issues. Effort should be made towards poverty reduction and community education on the impact of cultural practices on maternal health.

description: The FeII/MgII line flux ratio has been used to investigate the chemical evolution of high redshift active galactic nuclei (AGNs). No strong evolution has been found out to z~6, implying that the type 1a supernova activity has been already occurred in early universe. However, the trend of no evolution can be caused by the sample selection bias since the previous studies have utilized mostly very luminous AGNs, which may be already chemically matured at the observed redshift. As motivated by the previously reported correlation between AGN luminosity and metallicity, we investigate the FeII/MgII flux ratio over a large dynamic range of luminosity, by adding a new sample of 12 quasars at z~3, of which the lower luminosity limit is more than 1 dex smaller than that of the previously studied high-z quasars. Based on the Gemini/GNIRS observations, we find that the seven low-luminosity quasars with a mean bolometric luminosity log L_bol~46.5 \pm 0.2 has an average FeII/MgII ratio of 0.68 \pm 0.11 dex. This ratio is comparable to that of high-luminosity quasars (log L_bol~47.3 \pm 0.3) in our sample (i.e., FeII/MgII ratio of 0.59 \pm 0.15 dex) and that of the previously studied high-luminosity quasars at higher redshifts. One possible scenario is that the low-luminosity quasars in our sample are still relatively luminous and already chemically matured. To search for chemically-young AGNs, and fully understand the chemical evolution based on the FeII/MgII flux ratio, it is required to investigate much lower-luminosity AGNs.

description: Objective: The purpose of this study was to determine the bacteriological aetiology and incidence of Urinary Tract Infections (UTIs) and antibacterial susceptibility patterns among pregnant women attending antenatal clinics at the Federal Medical Centre in Bida, Niger-State, using the gold standard of culture. Study Design: Data were obtained from the Medical Microbiology Department Registry from pregnant women who attended routine antenatal clinics between January 2010 and December 2012.A total of 1242 pregnant women aged 15 to 54 years old had mid-stream urine samples taken. At the first antenatal appointment, samples were collected inside sterile disposable universal bottles from pregnant women suspected of having UTIs. SPSS version 16.0 was used to code, compute, and analyse the data, and p values of 0.05 were considered statistically significant. Results: Out of 1242 pregnant women between the ages of 15 and 54 in this study, our research found that the incidence of UTI was 46.1 percent, which was statistically significant (p = 0.046, with a mean age of 30.92 years and a standard deviation of 5.46). The most common uropathogen (60%) was Escherichia coli, followed by Staphylococcus aureus (28.3%). Escherichia coli was susceptible to Nitrofurantoin and Gentamycin (61.4%) and (51.5%) respectfully. Conclusion: The incidence of urinary tract infection in this study was 46.1% uropathogen, which is cause for concern among the general public. As a result, pregnant women should be screened for symptomatic or asymptomatic UTIs at antenatal clinics on a regular basis.

description: Abstract interior-boundary conditions (IBC's) allow for the direct description of the domain and the action of Hamiltonians for a certain class of ultraviolet-divergent models in Quantum Field Theory. The method was recently applied to models where nonrelativistic scalar particles are linearly coupled to a quantised field, the best known of which is the Nelson model. Since this approach avoids the use of ultraviolet-cutoffs, there is no need for a renormalisation procedure. Here, we extend the IBC method to pseudorelativistic scalar particles that interact with a real bosonic field. We construct the Hamiltonians for such models via abstract boundary conditions, describing their action explicitly. In addition, we obtain a detailed characterisation of their domain and make the connection to renormalisation techniques. As an example, we apply the method to two relativistic variants of Nelson's model, which have been renormalised for the first time by J. P. Eckmann and A. D. Sloan in 1970 and 1974, respectively.

description: We launch a fully relativistic study of the formation of supermassive black holes via the collapse of supermassive stars. Here we initiate our investigation by analyzing the secular evolution of supermassive stars up to the onset of dynamical instability and collapse. We focus on the effects of rotation, assumed uniform, and general relativity. We identify the critical configuration at which radial instability sets in and determine its structure in detail. We show that the key nondimensional ratios R/M, T/|W| and J/M^2 (T is the rotational kinetic energy and W is the gravitational potential energy) for this critical configuration are universal numbers, independent of the mass, spin, radius or history of the star. We compare results from an approximate, analytic treatment with a fully relativistic, numerical calculation and find good agreement. We solve analytically for the time evolution of these parameters up to the onset of instability. Cooling by photon radiation drives the evolution, which is accompanied by mass, angular momentum and entropy loss. The critical configuration serves as initial data for a future relativistic, hydrodynamical, 3D simulation of the collapse of an unstable supermassive star. Since this implosion starts from a universal critical configuration, the collapse is also uniquely determined and should produce a universal gravitational waveform. In this paper we briefly speculate on the possible outcome of this collapse and asses to what extent it offers a promising route to forming a supermassive black hole.

description: While the network traffic has seen exponential increase, the revenues have not maintained the same pace. New methods have to be explored to reduce this gap between traffic and revenue. One such method is convergence in networking layers. In this work, we study the convergence of OTN and DWDM layer from a network planning perspective. We compare the costs of planning networks without and with convergence and show that the multilayer planning offers least cost for higher traffic volumes.

description: We study spin correlations in Bose-Einstein condensates of spin 1 bosons with scatterings dominated by a total spin equal 2 channel. We show the low energy spin dynamics in the system can be mapped into an $o(n)$ nonlinear sigma model(NL$σ$M). $n=3$ at the zero magnetic field limit and $n=2$ in the presence of weak magnetic fields. In an ordered phase, the ground state has a hidden $Z_2$ symmetry and is degenerate under the group $[U(1)\times S^{n-1}]/Z_2$. We explore consequences of the hidden symmetry and propose some measurements to probe it.

description: Our statistical understanding of galaxy evolution is fundamentally driven by objects that lie above the surface-brightness limits of current wide-area surveys (mu ~ 23 mag arcsec^-2). While both theory and small, deep surveys have hinted at a rich population of low-surface-brightness galaxies (LSBGs) fainter than these limits, their formation remains poorly understood. We use Horizon-AGN, a cosmological hydrodynamical simulation to study how LSBGs, and in particular the population of ultra-diffuse galaxies (UDGs; mu > 24.5 mag arcsec^-2), form and evolve over time. For M* > 10^8 MSun, LSBGs contribute 47, 7 and 6 per cent of the local number, mass and luminosity densities respectively (~85/11/10 per cent for M* > 10^7 MSun). Today's LSBGs have similar dark-matter fractions and angular momenta to high-surface-brightness galaxies (HSBGs; mu < 23 mag arcsec^-2), but larger effective radii (x2.5 for UDGs) and lower fractions of dense, star-forming gas (more than x6 less in UDGs than HSBGs). LSBGs originate from the same progenitors as HSBGs at z > 2. However, LSBG progenitors form stars more rapidly at early epochs. The higher resultant rate of supernova-energy injection flattens their gas-density profiles, which, in turn, creates shallower stellar profiles that are more susceptible to tidal processes. After z ~ 1, tidal perturbations broaden LSBG stellar distributions and heat their cold gas, creating the diffuse, largely gas-poor LSBGs seen today. In clusters, ram-pressure stripping provides an additional mechanism that assists in gas removal in LSBG progenitors. Our results offer insights into the formation of a galaxy population that is central to a complete understanding of galaxy evolution, and which will be a key topic of research using new and forthcoming deep-wide surveys.

Some stochastic phenomena in a driven double-well system

description: We study the overdamped motion of a Brownian particle in a driven double-well system to understand various physical phenomena observed experimentally. These phenomena include hysteresis, stochastic resonance, and net unidirectional motion in a symmetric periodic system. We argue that the area of the hysteresis loop so defined is a good measure of synchronization (with respect to the applied field) of passages between the two wells. We find that stochastic resonance may be relevant even in case of large amplitude driving field due to a recently discovered phenomena of noise induced stability of unstable states. We try to find relation between some of these apparently different phenomena.

description: We study the time-independent modes of a massless scalar field in various black hole backgrounds, and show that for these black holes, the time-independent mode is localised at the horizon. A similar analysis is done for time-independent equilibrium modes of the five dimensional plane AdS black hole. A self-adjointness analysis of this problem reveals that in addition to the modes corresponding to the usual glueball states, there is a discrete infinity of other equilibrium modes with imaginary mass for the glueball. We suggest these modes may be related to a Savvidy-Nielsen-Olesen-like vacuum instability in QCD.
