description: Multimodal machine translation is the task of translating from a source text into the target language using information from other modalities. Existing multimodal datasets have been restricted to only highly resourced languages. In addition to that, these datasets were collected by manual translation of English descriptions from the Flickr30K dataset. In this work, we introduce MMDravi, a Multilingual Multimodal dataset for under-resourced Dravidian languages. It comprises of 30,000 sentences which were created utilizing several machine translation outputs. Using data from MMDravi and a phonetic transcription of the corpus, we build an Multilingual Multimodal Neural Machine Translation system (MMNMT) for closely related Dravidian languages to take advantage of multilingual corpus and other modalities. We evaluate our translations generated by the proposed approach with human-annotated evaluation dataset in terms of BLEU, METEOR, and TER metrics. Relying on multilingual corpora, phonetic transcription, and image features, our approach improves the translation quality for the underresourced languages.

description: We study solutions of type IIB string theory dual to ${\cal N}=4$ supersymmetric Yang-Mills theory on half of $\mathbb{R}^{3,1}$ coupled to holographic three-dimensional superconformal field theories (SCFTs) at the edge of this half-space. The dual geometries are asymptotically $AdS^5 \times S^5$ with boundary geometry $\mathbb{R}^{2,1} \times \mathbb{R}^+$, with a geometrical end-of-the-world (ETW) brane cutting off the other half of the asymptotic region of the would-be Poincaré $AdS^5 \times S^5$. We show that by choosing the 3D SCFT appropriately, this ETW brane can be pushed arbitrarily far towards the missing asymptotic region, recovering the "missing" half of Poincaré $AdS^5 \times S^5$. We also show that there are 3D SCFTs whose dual includes a wedge of Poincaré $AdS^5 \times S^5$ with an angle arbitrarily close to $π$, with geometrical ETW branes on either side.

description: We report the discovery of 3 new unbound hypervelocity stars (HVSs), stars traveling with such extreme velocities that dynamical ejection from a massive black hole (MBH) is their only suggested origin. We also detect a population of possibly bound HVSs. The significant asymmetry we observe in the velocity distribution -- we find 26 stars with v_rf > 275 km/s and 1 star with v_rf < -275 km/s -- shows that the HVSs must be short-lived, probably 3 - 4 Msun main sequence stars. Any population of hypervelocity post-main sequence stars should contain stars falling back onto the Galaxy, contrary to the observations. The spatial distribution of HVSs also supports the main sequence interpretation: longer-lived 3 Msun HVSs fill our survey volume; shorter-lived 4 Msun HVSs are missing at faint magnitudes. We infer that there are 96 +- 10 HVSs of mass 3 - 4 Msun within R < 100 kpc, possibly enough HVSs to constrain ejection mechanisms and potential models. Depending on the mass function of HVSs, we predict that SEGUE may find up to 5 - 15 new HVSs. The travel times of our HVSs favor a continuous ejection process, although a ~120 Myr-old burst of HVSs is also allowed.

description: We present $V$-band photometry of the 20,000 brightest asteroids using data from the All-Sky Automated Survey for Supernovae (ASAS-SN) between 2012 and 2018. We were able to apply the convex inversion method to more than 5,000 asteroids with more than 60 good measurements in order to derive their sidereal rotation periods, spin axis orientations, and shape models. We derive unique spin state and shape solutions for 760 asteroids, including 163 new determinations. This corresponds to a success rate of about 15%, which is significantly higher than the success rate previously achieved using photometry from surveys. We derive the first sidereal rotation periods for additional 69 asteroids. We find good agreement in spin periods and pole orientations for objects with prior solutions. We obtain a statistical sample of asteroid physical properties that is sufficient for the detection of several previously known trends, such as the underrepresentation of slow rotators in current databases, and the anisotropic distribution of spin orientations driven by the nongravitational forces. We also investigate the dependence of spin orientations on the rotation period. Since 2018, ASAS-SN has been observing the sky with higher cadence and deeper limiting magnitude, which will lead to many more new solutions in just a few years.

Firstly, DC and EL characterization at room temperature are summarized, then the parametric evolution during hot-electron step stress tests at the semi-on state was compared, the assumption for the degradation mechanism is that hot-electrons activated the pre-existing traps in the buffer, attenuate the electric field in the gate drain access region and damaging the gate contact, the parametric evolution during constant stresses is discussed.

description: Patat et al. recently inferred the existence of circumstellar material around a normal Type Ia supernova (SN) for the first time, finding time-variable Na I D absorption lines in the spectrum of SN 2006X. We present high-resolution spectroscopy of the bright SN Ia 2007af at three epochs and search for variability in any of the Na D absorption components. Over the time range from 4 days before to 24 days after maximum light, we find that the host-galaxy Na D lines appear to be of interstellar rather than circumstellar origin and do not vary down to the level of 18 mA (column density of 2 x 10^11 cm^-2). We limit any circumstellar absorption lines to be weaker than ~10 mA (6 x 10^10 cm^-2). For the case of material distributed in spherically symmetric shells of radius ~10^16 cm surrounding the progenitor system, we place an upper limit on the shell mass of ~(3 x 10^-8)/X Msun, where X is the Na ionization fraction. We also show that SN 2007af is a photometrically and spectroscopically normal SN Ia. Assuming that the variable Na D lines in SN 2006X came from circumstellar matter, we therefore conclude that either there is a preferred geometry for the detection of variable absorption components in Type Ia supernovae, or SN 2007af and SN 2006X had different types of progenitor systems.

description: Models of terrestrial planet formation predict that the final stages of planetary assembly, lasting tens of millions of years beyond the dispersal of young protoplanetary disks, are dominated by planetary collisions. It is through these giant impacts that planets like the young Earth grow to their final mass and achieve long-term stable orbital configurations. A key prediction is that these impacts produce debris. To date, the most compelling observational evidence for post-impact debris comes from the planetary system around the nearby 23 Myr-old A star HD 172555. This system shows large amounts of fine dust with an unusually steep size distribution and atypical dust composition, previously attributed to either a hypervelocity impact or a massive asteroid belt. Here, we report the spectrally resolved detection of a CO gas ring co-orbiting with dusty debris between ~6-9 au - a region analogous to the outer terrestrial planet region of our Solar System. Taken together, the dust and CO detections favor a giant impact between large, volatile-rich bodies. This suggests that planetary-scale collisions, analogous to the Moon-forming impact, can release large amounts of gas as well as debris, and that this gas is observable, providing a window into the composition of young planets.

description: We report a study of the low-temperature high-pressure phase diagram of the intermetallic compound PrCu$_2$, by means of molecular-field calculations and $^{63,65}$Cu nuclear-quadrupole-resonance (NQR) measurements under pressure. The pressure-induced magnetically-ordered phase can be accounted for by considering the influence of the crystal electric field on the $4f$ electron orbitals of the Pr$^{3+}$ ions and by introducing a pressure-dependent exchange interaction between the corresponding local magnetic moments. Our experimental data suggest that the order in the induced antiferromagnetic phase is incommensurate. The role of magnetic fluctuations both at high and low pressures is also discussed.

description: We consider the task of feature selection for reconstruction which consists in choosing a small subset of features from which whole data instances can be reconstructed. This is of particular importance in several contexts involving for example costly physical measurements, sensor placement or information compression. To break the intrinsic combinatorial nature of this problem, we formulate the task as optimizing a binary mask distribution enabling an accurate reconstruction. We then face two main challenges. One concerns differentiability issues due to the binary distribution. The second one corresponds to the elimination of redundant information by selecting variables in a correlated fashion which requires modeling the covariance of the binary distribution. We address both issues by introducing a relaxation of the problem via a novel reparameterization of the logitNormal distribution. We demonstrate that the proposed method provides an effective exploration scheme and leads to efficient feature selection for reconstruction through evaluation on several high dimensional image benchmarks. We show that the method leverages the intrinsic geometry of the data, facilitating reconstruction.
Approximating approximate reasoning: Fuzzy sets and the Ershov hierarchy

description: Computability theorists have introduced multiple hierarchies to measure the complexity of sets of natural numbers. The Kleene Hierarchy classifies sets according to the first-order complexity of their defining formulas. The Ershov Hierarchy classifies $Δ^0_2$ sets with respect to the number of mistakes that are needed to approximate them. Biacino and Gerla extended the Kleene Hierarchy to the realm of fuzzy sets, whose membership functions range in a complete lattice $L$ (e.g., the real interval $[0; 1]_\mathbb{R}$). In this paper, we combine the Ershov Hierarchy and fuzzy set theory, by introducing and investigating the Fuzzy Ershov Hierarchy. In particular, we focus on the fuzzy $n$-c.e. sets which form the finite levels of this hierarchy. Intuitively, a fuzzy set is $n$-c.e. if its membership function can be approximated by changing monotonicity at most $n-1$ times. We prove that the Fuzzy Ershov Hierarchy does not collapse; that, in analogy with the classical case, each fuzzy $n$-c.e. set can be represented as a Boolean combination of fuzzy c.e. sets; but that, contrary to the classical case, the Fuzzy Ershov Hierarchy does not exhaust the class of all $Δ^0_2$ fuzzy sets.

Holotype worker, MALAYSIA: Borneo, Kinabalu Nat. Park, Poring Hot Spring, East Ridge, 800 m, 1995 (C. Brühl) (USNM); 3 paratype workers, same locality as holotype (ANIC; USNM).
 Worker. Measurements (n=3): TL: 3.35–4.18; HW: 0.97–1.11; HL: 0.91–1.04; SL: 1.18–1.23; WL: 1.3–1.42; GL: 1.14–1.72. Indices: CI: 104–107; SI: 110–122.
Head brown, with lighter yellowish-brown mandibles and funiculi; head about as long as broad. Cuticular surface shiny and smooth, with scattered erect setae and sparse pubescence that is thickest in area under the eyes. Posterior margin complete. Scapes surpass posterior margin by about length of the first four funicular segments. Scapes with erect setae and a layer of pubescence, becoming denser distally. Mesosoma brown, smooth, and shiny, legs becoming lighter distally, especially tarsi, which are yellowish-brown. Mesosomal dorsum with scattered erect setae of varying lengths; cuticular surface without pubescence; legs with short erect setae. Pronotum rises at about 45° toward mesonotum; propodeum dorsum rounded, dome-like; declivity steep. Petiole triangular with posterior face longer than anterior face; gaster brown, with scattered erect setae and a dense layer of pubescence; cuticular surface shiny, and weakly regureticulate.
 Etymology: The species epithet is Greek for hair, in reference to the pubescence that covers the gaster of this species.
 Discussion: This species is easily distinguished from other Euprenolepis species by the dense layer of pubescence on the gaster. Only two other species also have pubescence on the gaster: E. procera and E. zeta. Euprenolepis thrix is easily distinguishable from E. procera by the smooth surface of the cephalic and mesosomal cuticle. Euprenolepis thrix is distinguishable from E. zeta by denser gastral pubescence. Also, E. thrix and E. zeta have the head slightly broader than long (CI typically greater than 100), whereas other Euprenolepis have the head slightly longer than broad (CI typically less than 100). Shared body coloration, head shape, and the presence of pubescence on the gaster probably indicate that E. thrix and E. zeta are close relatives.

description: This paper tries to tell the story of the general linear model, which saw the light of day 200 years ago, and the assumptions underlying it. We distinguish three principal stages (ignoring earlier more isolated instances). The model was first proposed in the context of astronomical and geodesic observations, where the main source of variation was observational error. This was the main use of the model during the 19th century. In the 1920's it was developed in a new direction by R.A. Fisher whose principal applications were in agriculture and biology. Finally, beginning in the 1930's and 40's it became an important tool for the social sciences. As new areas of applications were added, the assumptions underlying the model tended to become more questionable, and the resulting statistical techniques more prone to misuse.

Petiole triangular with posterior face longer than anterior face; gaster brown, with scattered erect setae and a sparse layer of pubscence; cuticular surface shiny and weakly reguoreticulate.
 Etymology: The species epithet is Greek. Zeta is the sixth letter of the Greek alphabet, and this was the sixth and final new species discovered during the course of this revision.
 Additional material examined: MALAYSIA: Borneo, Sabah, Danum Valley, West Trail P 1, 250 m, 17.viii.1997 (C. Brühl); Borneo; Kinabalu Nat. Park; Poring Hot Spring, East Ridge; 560 m (C. Brühl).
 Discussion: This species is most likely to be confused with E. thrix, but E. zeta has far less pubescence on the gaster. As in E. thrix, E. zeta does have the head wider than long, an unusual trait among Euprenolepis species. Based on overall morphological similarity, including the head shape and presence of pubescence on the gaster, it is likely that E. thrix and E. zeta are close relatives.

description: We investigate the possible superconducting pairing symmetries which would account for the latest experimental results on the Bechgaard salts. Using a renormalization group (R.G) technique we calculate the couplings of the singlet and triplet interactions in the quasi 1D Hamiltonian. In the presence of interchain interactions, the singlet and triplet couplings are of the same order of magnitude. The renormalized couplings are then used in an RPA calculation to evaluate the critical fields of superconductivity for the two dominant order parameter symmetries in the R.G flow, i.e, the dx2-y2 and fy symmetries. It is shown that, for the standard values of the anisotropy ratio of the Fermi surface, the critical fields of the singlet symmetry are strongly reduced. A reentrant superconductivity is however still present for the triplet state.
The Star Formation Law in a Multifractal ISM

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The surface density of the star formation rate in different galaxies, as well as in different parts of a single galaxy, scales nonlinearly with the surface density of the total gas. This observationally established relation is known as the Kennicutt-Schmidt star formation law. The slope of the star formation law has been shown to change with the density of the gas against which the star formation rate is plotted. This dependence implies a nonlinear scaling between the dense gas and the total gas surface densities within galaxies. Here, we explore a possible interpretation of this scaling as a property of the geometry of the interstellar medium (ISM), and we find that it arises naturally if the topology of the ISM is multifractal. Under the additional assumption that, at very high densities, the star formation timescale is roughly constant, the star formation law itself can also be recovered as a consequence of the multifractal geometry of the ISM. The slope of the scaling depends on the width of the global probability density function (PDF), and is between 1.5 and 1.6 for wide PDFs relevant to high-mass systems, while it is higher for narrower PDFs appropriate for lower-mass dwarf galaxies, in agreement with observations.

description: We use hydrodynamic equations to study the formation of Faraday waves in a superfluid Fermi gas at zero temperature confined in a strongly elongated cigar-shaped trap. First, we treat the role of the radial density profile in the limit of an infinite cylindrical geometry and analytically evaluate the wavelength of the Faraday pattern. The effect of the axial confinement is fully taken into account in the numerical solution of hydrodynamic equations and shows that the infinite cylinder geometry provides a very good description of the phenomena.

description: By using Monte Carlo numerical simulation, this work investigates the phase behavior of systems of hard infinitesimally-thin circular arcs, from an aperture angle $θ\rightarrow 0$ to an aperture angle $θ\rightarrow 2 π$, in the two-dimensional Euclidean space. Except in the isotropic phase at lower density and in the (quasi)nematic phase that solely forms for sufficiently small values of $θ$ and at intermediate values of density, in the other phases that form, including the isotropic phase at higher density, hard infinitesimally-thin circular arcs auto-assemble to form clusters. These clusters are either filamentous, for smaller values of $θ$, or roundish, for larger values of $θ$. Provided density is sufficiently high, the filaments lengthen, merge and straighten to finally produce a filamentary phase while the roundels compact and dispose themselves with their centers of mass at the sites of a triangular lattice to finally produce a cluster hexagonal phase.

description: Recent advances in quantum key distribution (QKD) have given rise to systems that operate at transmission periods significantly shorter than the dead times of their component single-photon detectors. As systems continue to increase in transmission rate, security concerns associated with detector dead times can limit the production rate of sifted bits. We present a model of high-speed QKD in this limit that identifies an optimum transmission rate for a system with given link loss and detector response characteristics.

A number of complications are discussed, includingÊ the need to impute homeless counts to areas of Êthe CountyÊ not sampled. We conclude that, despite their imperfections, estimated counts provided useful and credible information to the stakeholders involved.

Mirror dark matter discovered?

description: Recent astrophysical data indicates that dark matter shows a controversial behaviour in galaxy cluster collisions. In case of the notorious Bullet cluster, dark matter component of the cluster behaves like a collisionless system. However, its behaviour in the Abell 520 cluster indicates a significant self-interaction cross-section. It is hard for the WIMP based dark matter models to reconcile such a diverse behaviour. Mirror dark matter models, on the contrary, are more flexible and for them diverse behaviour of the dark matter is a natural expectation.

An investigation into Hegel’s theory of tragedy
Creators: name: Black, Pamela Ann
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I deal primarily with Hegel's theory of tragedy, in an attempt to both explicate and evaluate his ideas in this area. The works of Hegel upon which I have based my observations include the chapter entitled Spirit in his Phenomenology of Spirit and the section on Dramatic Poetry in his Philosophy of Fine Art. First I delineate the kind of moral dilemma which Hegel asserted as intrinsic to tragedy and then I evaluate the theory which arises out of this belief. The Hegelian terminology necessary for this sort of discussion is set out in the first two chapters. An explanation is given for such terms as Spirit, Freedom, the Universal, the Absolute and the self-defined subject. Hegel's interest in the Greek po1i s - the tension between the autonomy of the individual and the demands of the state and his concepts of Christian agape and Fate are also discussed. In the second chapter Hegel's historical dialectic is explored to further clarify his concept of Spirit and to provide the context in which he first presents us with the Antigone, which is his major vehicle for the abstraction of his theory of tragedy from the rest of his system. At this stage the basic ingredients of tragedy can be clearly defined, i.e., familial obligation versus civic duty. I discuss the possibility of tragic division within Spirit itself, the case in which morally justifiable belief and action may be at odds with action and belief which is equally justifiable. The third chapter offers a more thorough examination of the ethical duties which Hegel thought were unique to family life and the relation these bore to the Universal. Then a brief exegesis of the Antigone is given, followed by the philosophical significance which Hegel perceived in the play's major events and in the relationships therein depicted. In the final chapter I deal with Hegel's attempt to extend his theory to include modern tragedy. I discuss the level of coherence and consistency which he maintains and the value of his expanded theory. As he contends that modern tragedy emphasizes The individual and the needs and desires of his particular personality or character, I follow up on Quinton's query about whether Hegel's theory can hold up once we have taken the ethical significance away from the action in tragedy. Finally, I discuss what "the tragic view of life" can be said to mean for Hegel. Is he the optimist he is generally taken for and are all spheres of action and belief in his ethical world ultimately concordant and harmonious? Or, indeed, does Hegel consistently support a yes or no answer to this latter question, along with all its ensuing implications for tragedy and Spirit.

description: The quasar 3C 279 is one of the best-studied flat spectrum radio quasars. It is located at a comparatively large redshift of z=0.536: E>100 GeV observations of such distant sources were until recently impossible both due to the expected steep energy spectrum and the expected attenuation of the gamma-rays by the extragalactic background light. Here we present results on the observation of 3C 279 with the MAGIC telescope in early 2006. We report the detection of a significant very high energy gamma-ray signal in the MAGIC energy range on the observation night of 2006 February 23.

Orbit evolution in growing stellar bars: Bar-supporting orbits at the vertical ILR region

description: We investigate the evolution of orbital shapes at the Inner Lindblad Resonance region of a rotating three-dimensional bar, the mass of which is growing with time. We evaluate in time-dependent models, during a 5 Gyr period, the importance of orbits with initial conditions known to play a significant role in supporting peanut-like structures in autonomous systems. These orbits are the central family of periodic orbits (x1) and vertical perturbations of it, orbits of its standard three-dimensional bifurcations at the region (x1v1 and x1v2), as well as orbits in their neighbourhood. The knowledge of the regular or chaotic character of these orbits is essential as well, because it allows us to estimate their contribution to the support of a rotating bar and, more importantly, the dynamical mechanisms that make it possible. This is calculated by means of the GALI2 index. We find that orbital patterns existing in the autonomous case, persist for longer times in the more massive bar models, and even more so in a model in which the central spheroid component of our adopted galactic potential becomes rather insignificant. The peanut-supporting orbits which we find, have a regular or, in most cases, a weakly chaotic character. There are cases in which orbits starting close to unstable periodic orbits in an autonomous model behave as regular and support the bar when its mass increases with time. An approximation for the orbital dynamics of our non-autonomous models at a certain time, can be considered that of the corresponding frozen system around that time.

Failed-Transition outbursts in Black hole low-mass X-ray binaries

description: Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst. Based on the X-ray spectrum and variability, this evolution can be divided into three canonical states: low/hard, intermediate and high/soft state. BH LMXBs evolve from the low/hard to the high/soft state through the intermediate state in some outbursts (here called "full outbursts"). However, in other cases, BH LMXBs undergo outbursts in which the source never reaches the high/soft state, here called "Failed-Transition outburst" (FT outbursts). From a sample of 56 BH LMXBs undergoing 128 outbursts, we find that $\sim$36% of these BH LMXBs experienced at least one FT outburst, and that FT outbursts represent $\sim$33% of the outbursts of the sample, showing that these are common events. We compare all the available X-ray data of full and FT outbursts of BH LMXBs from RXTE/PCA, Swift/BAT and MAXI and find that FT and full outbursts cannot be distinguished from their X-ray light curves, HIDs or X-ray variability during the initial 10-60 days after the outburst onset. This suggests that both types of outbursts are driven by the same physical process. We also compare the optical and infrared (O/IR) data of FT and full outbursts of GX 339-4. We found that this system is generally brighter in O/IR bands before an FT outburst, suggesting that the O/IR flux points to the physical process that later leads to a full or an FT outburst. We discuss our results in the context of models that describe the onset and evolution of outbursts in accreting X-ray binaries.

description: The aim of this study was to analyze the level of resilience of older practitioners (GP) and non-exercising (GNP) as their sociodemographic characteristics, health conditions and stressful events. The study included 164 elderlies, being 85 GP and 79 GNP. We used a diagnostic plug to collect sociodemographic data, health conditions, the Inventory of Stressful Events and Resilience Scale. We used the descriptive and inferential statistics. No significant difference in the level of resilience between the groups (p= 0.404). The old GP with higher education had higher resilience and lower intensity of stressful events. In both groups, the highest level of resilience was associated with lower intensity of stressful events. The level of resilience is not related to physical exercise, but older women who regularly exercise and have a higher level of resilience have lower intensity of stressful events.
