description: Strong (B >> 10^9 G) and superstrong (B > 10^{14} G) magnetic fields profoundly affect many thermodynamic and kinetic characteristics of dense plasmas in neutron star envelopes. In particular, they produce strongly anisotropic thermal conductivity in the neutron star crust and modify the equation of state and radiative opacities in the atmosphere, which are major ingredients of the cooling theory and spectral atmosphere models. As a result, both the radiation spectrum and the thermal luminosity of a neutron star can be affected by the magnetic field. We briefly review these effects and demonstrate the influence of magnetic field strength on the thermal structure of an isolated neutron star, putting emphasis on the differences brought about by the superstrong fields and high temperatures of magnetars. For the latter objects, it is important to take proper account of a combined effect of the magnetic field on thermal conduction and neutrino emission at densities ρ> 10^{10} g cm^{-3}. We show that the neutrino emission puts a B-dependent upper limit on the effective surface temperature of a cooling neutron star.

description: Utilizing the sensor characteristics of the audio, visible camera, and thermal camera, the robustness of person recognition can be enhanced. Existing multimodal person recognition frameworks are primarily formulated assuming that multimodal data is always available. In this paper, we propose a novel trimodal sensor fusion framework using the audio, visible, and thermal camera, which addresses the missing modality problem. In the framework, a novel deep latent embedding framework, termed the AVTNet, is proposed to learn multiple latent embeddings. Also, a novel loss function, termed missing modality loss, accounts for possible missing modalities based on the triplet loss calculation while learning the individual latent embeddings. Additionally, a joint latent embedding utilizing the trimodal data is learnt using the multi-head attention transformer, which assigns attention weights to the different modalities. The different latent embeddings are subsequently used to train a deep neural network. The proposed framework is validated on the Speaking Faces dataset. A comparative analysis with baseline algorithms shows that the proposed framework significantly increases the person recognition accuracy while accounting for missing modalities.

Efficient form of the LANS-alpha turbulence model in a primitive-equation ocean model

description: The Lagrangian-Averaged Navier-Stokes alpha (LANS-alpha) model is a turbulence parameterization that has been shown to capture some of the most important features of high resolution ocean modeling at lower resolution. Simulations using LANS-alpha in the POP primitive-equation ocean model resemble doubled-resolution simulations of standard POP in statistics like kinetic energy, eddy kinetic energy, and potential temperature fields. The computational cost of adding LANS-alpha is only 27% for our most efficient implementation, as compared to a factor of 8-10 for a doubling of resolution. The LANS-alpha model improves turbulence statistics with an additional nonlinear term and a smoothed advecting velocity. In this work we investigate different kinds of smoothing techniques and their effect on the LANS-alpha model's results and efficiency. We show that we can substitute convolution filters for full Hemlholtz inversions and produce similar results at a significantly lower expense. When constructing filters for LANS-alpha in a primitive-equation ocean model the filter weights must be chosen carefully, otherwise a pressure-velocity instability will be excited. We show analytically that certain ranges of filter weights are unstable, and confirm this with numerical experiments. Our stability criterion also guarantees that the kinetic energy is well defined, and that the filtered velocity is smoother that the original velocity.

description: The IAU/IUGG Working Group on "Nutation for a non-rigid Earth", led by Véronique Dehant, won the European Descartes Prize in 2003, for its work developing a new model for the precession and the nutations of the Earth. This model (MHB2000, Mathews et al. 2002) was adopted by the IAU (International Astronomical Union) during the General Assembly in Manchester, in 2000. It is based (i) on some improvements for the precession model (with respect to the previous one of Lieske et al. 1977) owing to the VLBI technique, and (ii) on a very accurate nutation model, close to the observations. With this prize, the Descartes nutation project could offer for international scientists some grants, to be used for further improvements of the precession-nutation Earth model. At the IGG (Institute of Geodesy and Geophysics), with the OCCAM 6.1 VLBI analysis software and the best data and models available, we re-analyzed the whole VLBI sessions available (from 1985 till 2005) solving for the Earth Orientation Parameters (EOP). In this paper we present the results obtained for the EOP and more particularly for the nutation series. We compare them with the other IVS analysis centers results, as well as with the IVS combined EOP series from the analysis coordinator. The series are in good agreement, except for the polar motion coordinates that show a shift with respect to the other ones and that we discuss here. Finally, we analyse the nutation series in the framework of the free core nutation (FCN) study and modelisation.

Interactive effects of alcohol and diabetes during pregnancy on the rat fetus
Creators: name: Lin, Yi
Publisher: name: University of British Columbia
Year: 2008

description: Substantial literature indicates that maternal diabetes has teratogenic effects on the fetus and that consumption of alcohol during gestation is also teratogenic to the fetus. In the present study, Sprague-Dawley female rats were used to test whether small amounts of alcohol administered during organogenesis has an effect on the outcome of pregnancy in nondiabetic rats; to confirm the teratogenic effect of diabetes on fetuses; and to establish whether there is an interaction between alcohol and diabetes on the outcome of pregnancy. All rats were fed Purina rat chow and tap water ad libitum. Diabetes was induced by tail vein administration of streptozotocin (60 mg/kg body weight) one week before mating. Alcohol was administered during organogenesis (days 6-11 of gestation) intragastrically. The incidence and types of external and skeletal malformations were recorded in the fetuses of all treatment groups on day 21 of gestation. In addition, the fetal development was followed by assessing the ossification of the skeleton on gestational day 21 with the aid of alizarin red S and alcian blue 8GS staining. The results of this investigation support the view of previous studies that maternal diabetes is teratogenic to the offspring in terms of significantly increased malformation rates, and retarded fetal development (smaller fetal weight, bigger placenta, and retarded skeletal ossification compared to controls). Consumption of a small amount of alcohol (2g/kg/day) during organogenesis (days 6-11 of gestation) did not seem to intoxicate the dams, the body weight gain was at a normal rate, and there was a bigger fetal/placental ratio compared to controls. In terms of skeletal development, alcohol exposure seemed to enhance bone development. However, there were a few fetuses with absence of ossification centers in the hyoid bone and the short 13th rib which were significantly different from other treatment groups. Whether this represents retarded skeletal development is not clear. In the present study, a significant interaction between maternal diabetes and alcohol administration during organogenesis was observed. The fetal external malformation rate was significantly increased in diabetic rats exposed to alcohol compared to diabetic rats not exposed to alcohol. Furthermore, more fetuses had poorly ossified thoracic vertebral centers, poorly ossified cervical arches, and poorly ossified supraoccipital bone in diabetic rats exposed to alcohol than in diabetic rats not exposed to alcohol. These observations suggest that a small amount of alcohol consumption during organogenesis could possibly exacerbate the embryotoxic effects of maternal diabetes.

description: We consider flows $(X,T)$, given by actions $(t, x) \to tx$, on a compact metric space $X$ with a discrete $T$ as an acting group. We study a new class of flows - the \textsc{Strongly Rigid} ($ \mathbf {SR} $) \ flows, that are properly contained in the class of distal ($ \mathbf D $) flows and properly contain the class of all equicontinuous ($ \mathbf {EQ} $) flows. Thus, $\mathbf {EQ} \ \text{flows} \subsetneqq \mathbf {SR} \ \text{flows} \subsetneqq \mathbf{ D} \ \text{flows}$. The concepts of equicontinuity, strong rigidity and distality coincide for the induced flow $(2^X,T)$. We observe that strongly rigid $(X,T)$ gives distinct properties for the induced flow $(2^X,T)$ and its enveloping semigroup $E(2^X)$. We further study strong rigidity in case of particular semiflows $(X,S)$, with $S$ being a discrete acting semigroup.
Child universes UV regularization?

description: It is argued that high energy density excitations, responsible for UV divergences in quantum field theories, including quantum gravity, are likely to be the source of child universes which carry them out of the original space time. This decoupling prevents these high UV excitations from having any influence on physical amplitudes. Child universe production could therefore be responsible for UV regularization in quantum field theories which takes into account gravitational effects. Also child universe production in the last stages of black hole evaporation, the prediction of absence of tranplanckian primordial perturbations, connection to the minimum length hypothesis and in particular connection to the maximal curvature hypothesis are discussed.

description: The competition between the formation and destruction of coronene clusters under interstellar conditions is investigated theoretically. The unimolecular nucleation of neutral clusters is simulated with an atomic model combining an explicit classical force field and a quantum tight-binding approach. Evaporation rates are calculated in the framework of the phase space theory and are inserted in an infrared emission model and compared with the growth rate constants. It is found that, in interstellar conditions, most collisions lead to cluster growth. The time evolution of small clusters (containing up to 312 carbon atoms) was specifically investigated under the physical conditions of the northern photodissociation region of NGC 7023. These clusters are found to be thermally photoevaporated much faster than they are reformed, thus providing an interpretation for the lowest limit of the interstellar cluster size distribution inferred from observations. The effects of ionizing the clusters and density heterogeneities are also considered. Based on our results, the possibility that PAH clusters could be formed in PDRs is critically discussed.

The algebraic Bethe ansatz discussion is conducted on two special classes of $τ^{(2)}$ which include the superintegrable chiral Potts model. We then perform the parallel discussion on the XXZ spin chain at roots of unity, and demonstrate that the $sl_2$-loop-algebra symmetry exists for the root-of-unity XXZ spin chain with a higher spin, where the evaluation parameters for the symmetry algebra are identified by the explicit Fabricius-McCoy current for the Bethe states. Parallels are also drawn to the comparison with the superintegrable chiral Potts model.

description: Building predictive models for robust and accurate prediction of stock prices and stock price movement is a challenging research problem to solve. The well-known efficient market hypothesis believes in the impossibility of accurate prediction of future stock prices in an efficient stock market as the stock prices are assumed to be purely stochastic. However, numerous works proposed by researchers have demonstrated that it is possible to predict future stock prices with a high level of precision using sophisticated algorithms, model architectures, and the selection of appropriate variables in the models. This chapter proposes a collection of predictive regression models built on deep learning architecture for robust and precise prediction of the future prices of a stock listed in the diversified sectors in the National Stock Exchange (NSE) of India. The Metastock tool is used to download the historical stock prices over a period of two years (2013- 2014) at 5 minutes intervals. While the records for the first year are used to train the models, the testing is carried out using the remaining records. The design approaches of all the models and their performance results are presented in detail. The models are also compared based on their execution time and accuracy of prediction.

description: In this work we derive a lower bounds for the Hausdorff and fractal dimensions of the global attractor of the Sabra shell model of turbulence in different regimes of parameters. We show that for a particular choice of the forcing and for sufficiently small viscosity term $ν$, the Sabra shell model has a global attractor of large Hausdorff and fractal dimensions proportional to $\log_λν^{-1}$ for all values of the governing parameter $ε$, except for $ε=1$. The obtained lower bounds are sharp, matching the upper bounds for the dimension of the global attractor obtained in our previous work. Moreover, we show different scenarios of the transition to chaos for different parameters regime and for specific forcing. In the ``three-dimensional'' regime of parameters this scenario changes when the parameter $ε$ becomes sufficiently close to 0 or to 1. We also show that in the ``two-dimensional'' regime of parameters for a certain non-zero forcing term the long-time dynamics of the model becomes trivial for any value of the viscosity.

description: Twist engineering, or the alignment of two-dimensional (2D) crystalline layers with desired orientations, has led to tremendous success in modulating the charge degree of freedom in hetero- and homo-structures, in particular, in achieving novel correlated and topological electronic phases in moiré electronic crystals. However, although pioneering theoretical efforts have predicted nontrivial magnetism and magnons out of twisting 2D magnets, experimental realization of twist engineering spin degree of freedom remains elusive. Here, we leverage the archetypal 2D Ising magnet chromium triiodide (CrI3) to fabricate twisted double bilayer homostructures with tunable twist angles and demonstrate the successful twist engineering of 2D magnetism in them. Using linear and circular polarization-resolved Raman spectroscopy, we identify magneto-Raman signatures of a new magnetic ground state that is sharply distinct from those in natural bilayer (2L) and four-layer (4L) CrI3. With careful magnetic field and twist angle dependence, we reveal that, for a very small twist angle (~ 0.5 degree), this emergent magnetism can be well-approximated by a weighted linear superposition of those of 2L and 4L CI3 whereas, for a relatively large twist angle (~ 5 degree), it mostly resembles that of isolated 2L CrI3. Remarkably, at an intermediate twist angle (~ 1.1 degree), its magnetism cannot be simply inferred from the 2L and 4L cases, because it lacks sharp spin-flip transitions that are present in 2L and 4L CrI3 and features a dramatic Raman circular dichroism that is absent in natural 2L and 4L ones. Our results demonstrate the possibility of designing and controlling the spin degree of freedom in 2D magnets using twist engineering.

description: We present here the sensitive HCN(1-0) observations made with the VLA of two submillimeter galaxies and two QSOs at high-redshift. HCN emission is the signature of dense molecular gas found in GMC cores, the actual sites of massive star formation. We have made the first detection of HCN in a submillimeter galaxy, SMM J16359+6612. The HCN emission is seen with a signal to noise ratio of 4$σ$ and appears to be resolved as a double-source of $\approxlt 2''$ separation. Our new HCN observations, combined with previous HCN detections and upper limits, show that the FIR/HCN ratios in these high redshift sources lie systematically above the FIR/HCN correlation established for nearby galaxies by about a factor of 2. Even considering the scatter in the data and the presence of upper limits, this is an indication that the FIR/HCN ratios for the early Universe molecular emission line galaxies (EMGs) deviate from the correlation that fits Galactic giant molecular cloud cores, normal spirals, LIRGs, and ULIRGs. This indicates that the star formation rate per solar mass of dense molecular gas is higher in the high-$z$ objects than in local galaxies including normal spirals LIRGs and ULIRGs. The limited HCN detections at high-redshift show that the HCN/CO ratios for the high-$z$ objects are high and are comparable to those of the local ULIRGs rather than those of normal spirals. This indicates that EMGs have a high fraction of dense molecular gas compared to total molecular gas traced by CO emission.

description: This article uses data from the German microcensuses of 2007 and 2012 to examine gender differences in welfare reliance among lone parents. Binary logistic regression was employed as the method of analysis. We show that the risk of welfare benefit receipt is lower among lone fathers than lone mothers. We also find that these gender differences can be partially explained by the socio-economic characteristics of lone fathers; compared to lone mothers, lone fathers are, on average, better educated and more likely to be living with older children. Gender differences decreased over time among parents who have never married, but remained constant among divorced parents. We present a discussion of our findings in light of recent policy reforms, in particular the reform of the German Maintenance Law of 2008, which curbed the ability of a divorced parent to collect support from an ex-spouse.

description: We demonstrate experimentally that the spectral broadening of CW supercontinuum can be controlled by using photonic crystal fibers with two zero-dispersion wavelengths pumped by an Yb fiber laser at 1064 nm. The spectrum is bounded by two dispersive waves whose spectral location depends on the two zero-dispersion wavelengths of the fiber. The bandwidth of the generated spectrum and the spectral power density may thus be tailored for particular applications, such as high-resolution optical coherence tomography or optical spectroscopy.

description: The strong excitonic effect in monolayer transition metal dichalcogenide (TMD) semiconductors has enabled many fascinating light-matter interaction phenomena. Examples include strongly coupled exciton-polaritons and nearly perfect atomic monolayer mirrors. The strong light-matter interaction also opens the door for dynamical control of mechanical motion through the exciton resonance of monolayer TMDs. Here we report the observation of exciton-optomechanical coupling in a suspended monolayer MoSe2 mechanical resonator. By moderate optical pumping near the MoSe2 exciton resonance, we have observed optical damping and anti-damping of mechanical vibrations as well as the optical spring effect. The exciton-optomechanical coupling strength is also gate-tunable. Our observations can be understood in a model based on photothermal backaction and gate-induced mirror symmetry breaking in the device structure. The observation of gate-tunable exciton-optomechanical coupling in a monolayer semiconductor may find applications in nanoelectromechanical systems (NEMS) and in exciton-optomechanics.

description: We discuss the dynamics of classical Dicke-type models, aiming to clarify the mechanisms by which coherent states could develop in potentially non-equilibrium systems such as semiconductor microcavities. We present simulations of an undamped model which show spontaneous coherent states with persistent oscillations in the magnitude of the order parameter. These states are generalisations of superradiant ringing to the case of inhomogeneous broadening. They correspond to the persistent gap oscillations proposed in fermionic atomic condensates, and arise from a variety of initial conditions. We show that introducing randomness into the couplings can suppress the oscillations, leading to a limiting dynamics with a time-independent order parameter. This demonstrates that non-equilibrium generalisations of polariton condensates can be created even without dissipation. We explain the dynamical origins of the coherence in terms of instabilities of the normal state, and consider how it can additionally develop through scattering and dissipation.

description: Online political advertising has grown significantly over the last few years. To monitor online sponsored political discourse, companies such as Facebook, Google, and Twitter have created public Ad Libraries collecting the political ads that run on their platforms. Currently, both policymakers and platforms are debating further restrictions on political advertising to deter misuses. This paper investigates whether we can reliably distinguish political ads from non-political ads. We take an empirical approach to analyze what kind of ads are deemed political by ordinary people and what kind of ads lead to disagreement. Our results show a significant disagreement between what ad platforms, ordinary people, and advertisers consider political and suggest that this disagreement mainly comes from diverging opinions on which ads address social issues. Overall our results imply that it is important to consider social issue ads as political, but they also complicate political advertising regulations.

We use it to determine the wave-functions of protected closed strings in these backgrounds and prove that their energies are protected to all orders in $α'$. We further apply the ABA to find the wave functions of protected states of $\mbox{AdS}_3\times\mbox{S}^3\times\mbox{S}^3\times \mbox{S}^1$ and its $\mathbf{Z}_2$ orbifold. Our findings match with protected spectrum calculations from supergravity, $\mbox{Sym}^N$ orbifolds and apply to the complete moduli space of these theories, excluding orbifold blow-up modes for which further analysis is necessary.

Constraints on Generalized Dark Energy from Recent Observations

description: Effects of a generalized dark energy fluid is investigated on cosmic density fluctuations such as cosmic microwave background. As a general dark energy fluid, we take into consideration the possibility of the anisotropic stress for dark energy, which has not been discussed much in the literature. We comprehensively study its effects on the evolution of density fluctuations along with that of non-adiabatic pressure fluctuation of dark energy, then give constraints on such a generalized dark energy from current observations. We show that, though we cannot find any stringent limits on the anisotropic stress or the non-adiabatic pressure fluctuation themselves, the constrains on the equation of state of dark energy can be affected in some cases by the nature of dark energy fluctuation characterized by these properties. This may have important implications to the strategy to study the nature of dark energy.

description: From Rybicki's analysis using the Fourier slice theorem, mathematically it is possible to reproduce uniquely an edge-on axisymmetric galaxy's 3D light distribution from its 2D surface brightness. Utilizing galaxies from a cosmological simulation, we examine the ability of Syer and Tremaine's made-to-measure method and Schwarzschild's method for stellar dynamical modeling to do so for edge-on oblate axisymmetric galaxies. Overall, we find that the methods do not accurately recover the 3D distributions, with the made-to-measure method producing more accurate estimates than Schwarzschild's method. Our results have implications broader than just luminosity density, and affect other luminosity-weighted distributions within galaxies, for example, age and metallicity.

The role of external non-rigid ankle bracing in the prevention of inversion injuries
Creators: name: Anderson, Daphne L.
Publisher: name: University of British Columbia
Year: 2008

description: Ankle bracing is rapidly becoming the accepted method for the prevention of inversion injuries among active individuals suffering from a chronic ankle instability. The purpose of this study was to measure the effectiveness of the non-rigid, Subtalar Stabilizer (STS) ankle brace under conditions similar to an unexpected fall which inextreme circumstances could lead to a lateral ligament injury. The "calcaneal inversion" angles, times, and forces were measured when the subject's right foot, bearing body weight, was suddenly inverted as the trap door of the support platform swung to a side slope of 22°. Thirty subjects, 15 female and 15 male participated in the study. The "overall inversion drop" was divided into two phases, "free-fall" and "loading". The results of the 2 (sex) by 4 (brace condition) ANOVAs followed by post-hoc Tukeys analyses showed the brace significantly (p<0.05) reduced the "calcaneal inversionangle" from 27.4° ± 6.1° to 18.3° ± 6.0° for the "overall drop", significantly lengthened the "inversion time" from 0.140 ± 0.040seconds to 0.184 ± 0.040 seconds for the "overall drop", and significantly reduced the "calcaneal inversion velocity" from 324.6 ±111.9 °/sec. to 165.2 ± 66.5 °/sec. during "loading", and from 278.7± 120.0 °/sec. to 183.0 ± 108.7 °/sec. for the "overall drop". Following exercise which incorporated lateral movements and sprinting, the STS ankle brace continued to provide significant(p<0.05) reduction in the "calcaneal inversion angle and velocity" however it lost some of its original effectiveness. Although the females had a significantly (p<0.05) greater "calcaneal inversion range of motion" during "loading" there was no significant difference for the "overall drop" (33.0° ± 7.0° for the females versus 29.5° ±6.5° for the males). Therefore, it was concluded that the ankles of females are not more flexible in the frontal plane than the ankles of males. This study did not support the mechanism whereby braces play a role in the prevention of inversion injuries by enhancing afferent nerve fibres in order to prematurely stimulate the protective peroneal muscles. Evidence indicates that it is more likely that the brace functions to limit motion by redistributing and supporting a proportion of the load experienced by the lateral ligaments of the ankle during sudden inversion. The results of this study suggest that the non-rigid STS ankle brace has at least a "four fold" purpose in its role in the prevention of inversion injuries: 1) to significantly restrict the degree of "calcanealin version range of motion" during an unexpected fall and 2) to significantly lengthen the time of inversion thereby decreasing the rate at which the calcaneus inverts during a sudden inversion drop,3) to maintain this support, significantly, following sprinting and lateral movement exercise, and 4) to provide a relatively equal amount of ankle restriction of motion for both active males and females.
