description: Recently, eigenmodes of rotating fluids, namely inertial modes, have received much attention in relation to their destabilization when coupled to gravitational radiation within neutron stars. However, these modes have been known for a long time by fluid dynamicists. We give a short account of their history and review our present understanding of their properties. Considering the case of a spherical container, we then give the exact solution of the boundary (Ekman) layer flow associated with inertial r-modes and show that previous estimations all underestimated the dissipation by these layers. We also show that the presence of an inner core has little influence on this dissipation. As a conclusion, we compute the window of instability in the Temperature/rotation plane for a crusted neutron star when it is modeled by an incompressible fluid.

description: Abstract: The Research on the Archaeology of Pastoralism in Tanzania (RAPT) team presents new research from the site of Luxmanda, and southernmost and largest known Pastoral Neolithic settlement site in eastern Africa, dating to ~3100 BP. Excavations have revealed a spatially complex site occupied by members of a community that herded cattle, sheep, goats, and donkeys. The discoveries of multiple hearths, possible house floors, and distinct collections of large lower grindstones are challenging current understandings of how ancient “mobile” pastoralists lived over 3,000 years ago – and what their legacies might be today.

description: We explore a connection of the forced Burgers equation with the Schrödinger (diffusive) interpolating dynamics in the presence of deterministic external forces. This entails an exploration of the consistency conditions that allow to interpret dispersion of passive contaminants in the Burgers flow as a Markovian diffusion process. In general, the usage of a continuity equation $\partial_tρ=-\nabla (\vec{v}ρ)$, where $\vec{v}=\vec{v}(\vec{x},t)$ stands for the Burgers field and $ρ$ is the density of transported matter, is at variance with the explicit diffusion scenario. Under these circumstances, we give a complete characterisation of the diffusive matter transport that is governed by Burgers velocity fields. The result extends both to the approximate description of the transport driven by an incompressible fluid and to motions in an infinitely compressible medium.

description: Recent experimental results indicate that phosphorus, a single-component system, can have two liquid phases: a high-density liquid (HDL) and a low-density liquid (LDL) phase. A first-order transition between two liquids of different densities is consistent with experimental data for a variety of materials, including single-component systems such as water, silica and carbon. Molecular dynamics simulations of very specific models for supercooled water, liquid carbon and supercooled silica, predict a LDL-HDL critical point, but a coherent and general interpretation of the LDL-HDL transition is lacking. Here we show that the presence of a LDL and a HDL can be directly related to an interaction potential with an attractive part and two characteristic short-range repulsive distances. This kind of interaction is common to other single-component materials in the liquid state (in particular liquid metals), and such potentials are often used to decribe systems that exhibit a density anomaly. However, our results show that the LDL and HDL phases can occur in systems with no density anomaly. Our results therefore present an experimental challenge to uncover a liquid-liquid transition in systems like liquid metals, regardless of the presence of the density anomaly.

description: We discuss how a cosmological magnetic field could affect the expansion of the universe, through its interaction with the spacetime geometry. The tension of the field lines means that the magneto-curvature coupling tends to accelerate positively curved regions and decelerate those with negative curvature. Depending on the equation of state of the matter, the effect varies from mimicking that of a cosmological constant to resembling a time-decaying quintessence. Most interestingly, the coupling between magnetism and geometry implies that even weak fields have a significant impact if the curvature contribution is strong. This leads to kinematical complications that can inhibit the onset of the accelerated phase in spatially open inflationary models. We employ a simple cosmological model to illustrate these effects and examine the conditions necessary for them to have a appreciable impact.

description: This project sought to determine if students at K-12 schools that have received High Performance Incentive (HPI) grants in the state of California in the United States do evidence higher scholastic achievement, based on publicly available results on state-wide standardized tests. Since its inception in 2006, the HPI grant program has provided supplemental funds for school districts to build school buildings with high performance attributes. The attributes are assessed by a High Performance Rating Criteria (HPRC), modeled after criteria set forth by the California Collaborative for High Performance Schools (CHPS). The criteria for indoor environmental quality include assessments of the building’s thermal, air quality, lighting and acoustic conditions. In this project, data on these conditions as submitted by schools receiving HPI grants, particularly related to acoustic conditions, were analyzed against that school’s Academic Performance Index (API). The API is based on student achievement results from the California Standardized Testing and Results Program (STAR), which includes both English/Language Arts and Math topic areas. Specifically, this paper reports results of statistical analyses to determine if there are significant differences on API and STAR student achievement results between HPI and non-HPI schools with similar demographics.
Vertical magneto-tunneling through a quantum dot and the density of states of small electronic systems

description: One-electron tunneling through a quantum dot with a strong magnetic field in the direction of the current is studied. The linear magneto-conductance is computed for a model parabolic dot with seven electrons in the intermediate states and for different values of the magnetic field. It is shown that the dot density of states at low excitation energies can be extracted from a precise measurement of the conductance at the upper edge of the Coulomb blockade diamond. We parametrized the density of states with a single ``temperature'' parameter (in the so called ``constant temperature approximation''), and found that this parameter depends very weakly on the magnetic field.

description: Avian pathogenic Escherichia coli (APEC) are important pathogens that cause serious economic losses to the poultry industry worldwide. The PhoP/Q system is essential for APEC pathogenicity, and its mutation leads to a decrease in ybjX gene expression, but whether ybjX regulated by PhoP/Q plays a role in pathogenicity remains unclear. The role of ybjX in APEC pathogenicity was investigated using a ybjX mutant strain constructed from APEC strain AE17 by the Red recombination method. The mutant strain displayed significantly reduced adherence to and invasion of chicken embryo fibroblast cell line (DF-1) cells. Moreover, N-phenyl-1-naphthylamine (NPN) assays revealed an increase in outer membrane permeabilization for the ybjX mutant, suggesting ybjX affected susceptibility to avian beta-defensin through this mechanism. The ybjX mutation increased susceptibility to avian beta-defensin 9 (AvBD9), and in vivo LD50 assays revealed reduced bacterial virulence in a chicken model. Taken together, these results indicated that mutation of ybjX may attenuate APEC pathogenicity, not only by affecting bacterial adhesion and invasion, but also via reducing resistance to avian beta-defensin by increasing outer membrane permeabilization of bacteria.
Percolation and jamming in random sequential adsorption of linear segments on square lattice

description: We present the results of study of random sequential adsorption of linear segments (needles) on sites of a square lattice. We show that the percolation threshold is a nonmonotonic function of the length of the adsorbed needle, showing a minimum for a certain length of the needles, while the jamming threshold decreases to a constant with a power law. The ratio of the two thresholds is also nonmonotonic and it remains constant only in a restricted range of the needles length. We determine the values of the correlation length exponent for percolation, jamming and their ratio.

description: In the mean-field approximation, the number density ρ(r) for the ground state of a Bose-Einstein condensate trapped by an external potential V(r) satisfies a classical field equation called the Gross-Pitaevskii equation. We show that quantum corrections to ρare dominated by quantum fluctuations with wavelengths of order 1/\sqrt{ρa}, where a is the S-wave scattering length. By expanding the equations for the Hartree-Fock approximation to second order in the gradient expansion, we derive local correction terms to the Gross-Pitaevskii equation that take into account the dominant effects of quantum fluctuations. We also show that the gradient expansion for the density breaks down at fourth order.

description: We analyze the violations of linear fluctuation-dissipation theorem (FDT) in the coarsening dynamics of the antiferromagnetic Ising model on percolation clusters in two dimensions. The equilibrium magnetic response is shown to be non linear for magnetic fields of the order of the inverse square root of the number of sites. Two extreme regimes can be identified in the thermoremanent magnetization: (i) linear response and out-of-equilibrium relaxation for small waiting times (ii) non linear response and equilibrium relaxation for large waiting times. The function $X(C)$ characterizing the deviations from linear FDT cross-overs from unity at short times to a finite positive value for longer times, with the same qualitative behavior whatever the waiting time. We show that the coarsening dynamics on percolation clusters exhibits stronger long-term memory than usual euclidian coarsening.

description: The braneworld model of gravity is well-known for several notable cosmological features such as self-acceleration originating from a geometric and not matter source, effective dark energy behavior with phantom characteristics but not leading to a Big-Rip singularity, rough resemblance to the $Λ$CDM evolution, etc. The dynamical system tools usually allow us to obtain generic conclusions on the global dynamics of a system over a wide range of initial conditions. With this motivation, in order to recover the important features of the braneworld model from a more global perspective, here, we investigate the global cosmological dynamics of the braneworld model using dynamical system techniques. We first analyze the case where there is just a normal matter on the brane and then extend the analysis to the case with an extra scalar field also trapped on the brane. In the presence of a scalar field, potentials belonging to different classes are considered. The stability behavior of critical points is examined using linear stability analysis and when necessary center manifold theory as well as numerical perturbation techniques are also used. To understand the global dynamics of a dynamical system, we utilized the Poincaré compactification method to capture the properties of all possible critical points. Applying dynamical system analysis, we found that brane gravity is consistent with observed actions of the Universe. In particular, our analysis shows that important cosmological behaviors like the long-lasting matter-dominated era, late time acceleration as well as the avoidance of Big-Rip singularity can be realized in brane gravity for a wide range of initial conditions.

description: Functional relations among the fusion hierarchy of quantum transfer matrices give a novel derivation of the TBA equations, namely without string hypothesis. This is demonstrated for two important models of 1D highly correlated electron systems, the supersymmetric $t-J$ model and the supersymmetric extended Hubbard model. As a consequence, "the excited state TBA" equations, which characterize correlation lengths, are explicitly derived for the $t-J$ model. To the authors' knowledge, this is the first explicit derivation of excited state TBA equations for 1D lattice electron systems.

description: In April 2017, the Rangitāiki River breached a stopbank, resulting in widespread flooding within the town of Edgecumbe, Bay of Plenty. The evacuation of the town and damage to homes led to major disruption for residents. The relocation of households, both temporary and permanent, had long-lasting effects on the community. A questionnaire to gather residents’ experiences during the event and subsequent recovery was hand-delivered to residential addresses in Edgecumbe in November 2020. Topics included housing damage, evacuation experiences, relocation decisions, timeframes that residents were out of their homes and demographics. Of the 605 surveys delivered, 119 were returned, giving a 19.7% response rate. This report presents the results of the data collected in table and graph formats but does not contain any interpretation or analysis. (auth)

Examples are the formation of clouds, the plankton dynamics and the optimization of combustion engines Diesel. Because of finite mass and size, the orbits inertial particles differ significantly from those of particle Lagrange, which is massless and moving always tangent to the velocity field. A uniform distribution Lagrange particulate motion in incompressible flow remain uniform forever, and if inertial particles show strong discrepancies. This phenomenon is known as grouping and understanding needed to solve many problems as it directly affects the rate collisions between particles. Unlike particles Lagrange, inertial particles are characterized by non - conservative dynamics.

A Robust Test for Detecting Non-Stationarity in Data from Gravitational Wave Detectors

description: It is difficult to choose detection thresholds for tests of non-stationarity that assume {\em a priori} a noise model if the data is statistically uncharacterized to begin with. This is a potentially serious problem when an automated analysis is required, as would be the case for the huge data sets that large interferometric gravitational wave detectors will produce. A solution is proposed in the form of a {\em robust} time-frequency test for detecting non-stationarity whose threshold for a specified false alarm rate is almost independent of the statistical nature of the ambient stationary noise. The efficiency of this test in detecting bursts is compared with that of an ideal test that requires prior information about both the statistical distribution of the noise and also the frequency band of the burst. When supplemented with an approximate knowledge of the burst duration, this test can detect, at the same false alarm rate and detection probability, bursts that are about 3 times larger in amplitude than those that the ideal test can detect. Apart from being robust, this test has properties which make it suitable as an online monitor of stationarity.

Cells with equal number of sides repel (with linear correlation) while cells with different number of sides attract (with NON-bilinear) for nearest neighbours, which cannot be explained by the maximum entropy argument. Also, the analysis indicates that froth is correlated up to the third shell neighbours at least, contradicting the conventional ideas that froth is not strongly correlated.

description: Here we confirm Melnick 34, an X-ray bright star in the 30 Doradus region of the Large Magellanic Cloud, as an SB2 binary comprising WN5h+WN5h components. We present orbital solutions using 26 epochs of VLT/UVES spectra and 22 epochs of archival Gemini/GMOS spectra. Radial-velocity monitoring and automated template fitting methods both reveal a similar high eccentricity system with a mass ratio close to unity, and an orbital period in agreement with the 155.1 +/- 1 day X-ray light curve period previously derived by Pollock et al. Our favoured solution derived an eccentricity of 0.68 +/- 0.02 and mass ratio of 0.92 +/- 0.07, giving minimum masses of Ma_sin^{3}(i) = 65 +/- 7 Msun and Mb_sin^{3}(i) = 60 +/- 7 Msun. Spectral modelling using WN5h templates with CMFGEN reveals temperatures of T ~53 kK for each component and luminosities of log(La/Lsun) = 6.43 +/- 0.08 and log(Lb/Lsun) = 6.37 +/- 0.08, from which BONNSAI evolutionary modelling gives masses of Ma = 139 (+21,-18) Msun and Mb = 127 (+17,-17) Msun and ages of ~0.6 Myrs. Spectroscopic and dynamic masses would agree if Mk34 has an inclination of i ~50°, making Mk34 the most massive binary known and an excellent candidate for investigating the properties of colliding wind binaries. Within 2-3 Myrs, both components of Mk34 are expected to evolve to stellar mass black holes which, assuming the binary system survives, would make Mk34 a potential binary black hole merger progenitor and gravitational wave source.

description: The structure of the renormalization-group flows in a model with three quartic coupling constants is studied within the $ε$-expansion method up to three-loop order. Twofold degeneracy of the eigenvalue exponents for the three-dimensionally stable fixed point is observed and the possibility for powers in $\sqrtε$ to appear in the series is investigated. Reliability and effectiveness of the $ε$-expansion method for the given model is discussed.

description: To develop next-generation electronics and high efficiency energy-harvesting devices, it is crucial to understand how charge and heat are transported at the nanoscale. Metallic atomic-size contacts are ideal systems to probe the quantum limits of transport. The thermal and electrical conductance of gold atomic contacts has been recently proven to be quantized at room temperature. However, a big experimental challenge in such measurements is represented by the fast breaking dynamics of metallic junctions at room temperature, which can exceed the typical response time of the thermal measurement. Here we use a break-junction setup that combines Scanning Tunneling Microscopy with suspended micro electro-mechanical systems with a gold-covered membrane and an integrated heater acting also as thermometer. By using other metals as tip materials, namely Pt, PtIr and W, we show heat transport measurements through single gold atomic contacts. The dependence of the thermal conductance is analysed as function of contact size and material used. We find that by using Pt and Pt-Ir tips we can maximize the mechanical stability and probability of forming single Au atomic contacts. We then show the quantization of the electrical and thermal conductance with the verification of the Wiedemann-Franz law at the atomic scale. We expect these findings to increase the flexibility of experimental techniques probing heat transport in metallic quantum point contacts and to enable the investigation of thermal properties of molecular junctions.

description: Electric dipole radiation can be controlled by coherent optical feedback, as has previously been studied by modulating the photonic environment for point dipoles placed both in optical cavities and near metal mirrors. In experiments involving fluorescent molecules, trapped ions and quantum dots the point nature of the dipole, its sub-unity quantum efficiency, and decoherence rate conspire to severely limit any change in total linewidth. Here we show that the transverse coherence of exciton emission in the monolayer two-dimensional (2D) material MoSe${}_2$ removes many of the fundamental physical limitations present in previous experiments. The coherent interaction between excitons and a photonic mode localized between the MoSe${}_2$ and a nearby planar mirror depends interferometrically on mirror position, enabling full control over the radiative coupling rate from near-zero to 1.8 meV and a corresponding change in exciton total linewidth from 0.9 to 2.3 meV. The highly radiatively broadened exciton resonance (a ratio of up to $3:1$ in our samples) necessary to observe this modulation is made possible by recent advances in 2D materials sample fabrication. Our method of mirror translation is free of any coupling to strain or DC electric field in the monolayer, which allows a fundamental study of this photonic effect. The weak coherent driving field in our experiments yields a mean excitation occupation number of ${\sim} 10^{-3}$ such that our experiments correspond to probing radiative reaction in the regime of perturbative quantum electrodynamics. This system will serve as a testbed for exploring new excitonic physics and quantum nonlinear optical effects.

description: Research since the Children and Families Act (2014) and the SEND Code of Practice 0-25 (DfE & DoH, 2015) has focused upon new processes for statutory assessment, the quality of Education, Health and Care plans and the success and/or failures of the bureaucratic systems put in place to administer these. This research uses the thinking tools of the French sociologist Pierre Bourdieu (1930 - 2002), to consider how statutory assessment is perceived within the field of SEND. A conceptual framework, influenced by Bourdieu’s field theory (1984) and Crossley’s social movement fields (2003), is employed to examine participants responses to questions about Education, Health and Care plans. Data is analysed to investigate the field of SEND; who the agents of the field are, what language is used about statutory assessment, where there are alliances and conflicts, and the cross-field effects. A Bourdieusian analysis is employed to carry out research which studies the values perceived in a statutory assessment and consider some reasons for the ever-increasing number of children and young people receiving EHCPs. Theories about the field of SEND and statutory assessment are discussed by illustrating the common-sense views surrounding Education, Health and Care plans, their metaphoric symbolism and perceived symbolic capital.

description: We sketch a particularly simple and compelling version of D-brane cosmology. Inspired by the semi-phenomenological Randall--Sundrum models, and their cosmological generalizations, we develop a variant that contains a single (3+1)-dimensional D-brane which is located on the boundary of a single bulk (4+1)-dimensional region. The D-brane boundary is itself to be interpreted as our visible universe, with ordinary matter (planets, stars, galaxies) being trapped on this D-brane by string theory effects. The (4+1)-dimensional bulk is, in its simplest implementation, adS_{4+1}, anti-de Sitter space. We demonstrate that a k=+1 closed FLRW universe is the most natural option, though the scale factor could quite easily be so large as to make it operationally indistinguishable from a k=0 spatially flat universe. (With minor loss of elegance, spatially flat and hyperbolic FLRW cosmologies can also be accommodated.) We demonstrate how this model can be made consistent with standard cosmology, and suggest some possible observational tests.

Microstructural Shear Localization in Plastic Deformation of Amorphous Solids
Creators: name: Langer, J. S.
Publisher: name: arXiv
Year: 2001
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The shear-transformation-zone (STZ) theory of plastic deformation predicts that sufficiently soft, non-crystalline solids are linearly unstable against forming periodic arrays of microstructural shear bands. A limited nonlinear analysis indicates that this instability may be the mechanism responsible for strain softening in both constant-stress and constant-strain-rate experiments. The analysis presented here pertains only to one-dimensional banding patterns in two-dimensional systems, and only to very low temperatures. It uses the rudimentary form of the STZ theory in which there is only a single kind of zone rather than a distribution of them with a range of transformation rates. Nevertheless, the results are in qualitative agreement with essential features of the available experimental data. The nonlinear theory also implies that harder materials, which do not undergo a microstructural instability, may form isolated shear bands in weak regions or, perhaps, at points of concentrated stress.

description: We present and discuss the "Tetrad Model", a large colour/flavour embedding of the Standard model which has an interacting ultraviolet fixed point. It is shown that its extended-Pati-Salam symmetry is broken radiatively via the Coleman-Weinberg mechanism, while the remaining electroweak symmetry is broken when mass-squared terms run negative. In the IR the theory yields just the Standard Model, augmented by the fact that the Higgs fields carry the same generation indices as the matter fields. It is also shown that the Higgs mass-squareds develop a hierarchical structure in the IR, from a UV theory that is asymptotically flavour symmetric, opening up an interesting direction for explaining the emergence of the observed flavour structure.
