description: Standard computer vision systems assume access to intelligently captured inputs (e.g., photos from a human photographer), yet autonomously capturing good observations is a major challenge in itself. We address the problem of learning to look around: how can an agent learn to acquire informative visual observations? We propose a reinforcement learning solution, where the agent is rewarded for reducing its uncertainty about the unobserved portions of its environment. Specifically, the agent is trained to select a short sequence of glimpses after which it must infer the appearance of its full environment. To address the challenge of sparse rewards, we further introduce sidekick policy learning, which exploits the asymmetry in observability between training and test time. The proposed methods learn observation policies that not only perform the completion task for which they are trained, but also generalize to exhibit useful "look-around" behavior for a range of active perception tasks.

description: In the course of the follow-up multiwavelength study of a deep radio survey we have discovered that the milli-Jansky radio source PDFJ011423 is a low-redshift (z = 0.65) extremely red galaxy (ERG) with K=15.3, R-K = 5.8 and J-K = 3.1. Optical, infrared and radio photometry, together with optical and near-infrared spectroscopy, reveal a heavily obscured galaxy (A_V=5-6, from the observed Balmer decrement) undergoing vigorous star formation and presenting an active galactic nucleus (AGN). PDFJ011423 is a representative member of the dusty ERG population, providing a local counterpart for studying more distant ERGs.

description: We perform 3D numerical simulations for merger of equal mass binary neutron stars in full general relativity preparing irrotational binary neutron stars in a quasiequilibrium state as initial conditions. Simulations have been carried out for a wide range of stiffness of equations of state and compactness of neutron stars, paying particular attention to the final products and gravitational waves. We take a fixed uniform grid in Cartesian coordinates with typical grid size $(293,293,147)$ in $(x,y,z)$ assuming a plane symmetry with respect to the equatorial plane. A result of one new large-scale simulation performed with grid size $(505,505,253)$ is also presented. We find that the final product depends sensitively on the initial compactness of the neutron stars: In a merger between sufficiently compact neutron stars, a black hole is formed in a dynamical timescale. As the compactness is decreased, the formation timescale becomes longer and longer. For less compact cases, a differentially rotating massive neutron star is formed instead of a black hole. In the case of black hole formation, the disk mass around the black hole appears to be smaller than 1% of the total rest mass. It is also indicated that waveforms of high-frequency gravitational waves after merger depend strongly on the compactness of neutron stars.

Formation and evolution of galactic disks with a multiphase numerical model

Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The formation and evolution of galactic disks are complex phenomena, where gas and star dynamics are coupled through star formation and the related feedback. The physical processes are so numerous and intricate that numerical models focus, in general, on one or a few of them only. We propose here a numerical model with particular attention to the multiphase nature of the interstellar medium; we consider a warm gas phase (> 10^4 K), treated as a continuous fluid by an SPH algorithm, and a cold gas phase (down to 10K), fragmented in clouds, treated by a low-dissipation sticky particles component. The two gas phases do not have the same dynamics, nor the same spatial distribution. In addition to gravity, they are coupled through mass exchanges due to heating/cooling processes, and supernovae feedback. Stars form out of the cold phase, and re-inject mass to the warm phase through SN explosions and stellar winds. The baryons are embedded in a live cold dark matter component. Baryonic disks, initially composed of pure gas, encounter violent instabilities, and a rapid phase of star formation, that slows down exponentially. Stars form in big clumps, that accumulate in the center to build a bulge. Exponential metallicity gradients are obtained. External infall of gas should be included to maintain a star formation rate in the disk comparable to what is observed in present disk galaxies.

description: The incipient motion conditions of large wood were tested in flume experiments using 48 handmade cylindrical logs of different lengths, diameters and densities. Their orientation to flow determined the motion: parallel logs slid, while oblique or transverse logs rolled. Log orientation, channel bed roughness, and log diameter had significance influence on entrainment depth. The logs’ density strongly influenced motion for logs parallel to flow. Logs oriented parallel to flow needed large entrainment depth to entrain than similar logs oriented oblique or transverse. Logs denser than water had high correlation with buoyancy, suggesting initial movement by floating, followed by either sliding or rolling downstream along the bed. From the modelled datasets, our results guided by the goodness of fit demonstrate that the floatation thresholds taken from global datasets should be applied with caution under different bed roughness conditions.

description: Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the most common building material, experiencing broad humidity variations over the lifetime of infrastructure. First, the liquid density distribution at intermediate to high relative humidities is obtained using a lattice gas density functional method together with a realistic nano-granular model of cement hydrates. The calculated adsorption/desorption isotherms and pore size distributions are discussed and compare well to nitrogen and water experiments. The standard method for pore size distribution determination from desorption data is evaluated. Then, the integration of the Korteweg liquid stress field around each cement hydrate particle provided the capillary forces at the nanoscale. The cement mesoscale structure was relaxed under the action of the capillary forces. Local irreversible deformations of the cement nano-grains assembly were identified due to liquid-solid interactions. The spatial correlations of the nonaffine displacements extend to a few tens of nm. Finally, the Love-Weber method provided the homogenized liquid stress at the micronscale. The homogenization length coincided with the spatial correlation length nonaffine displacements. Our results on the solid response to capillary stress field suggest that the micronscale texture is not affected by mild drying, while local irreversible deformations still occur. These results pave the way towards understanding capillary phenomena induced stresses in heterogeneous porous media ranging from construction materials, hydrogels to living systems.

description: Studying the response of materials to strain can elucidate subtle properties of electronic structure in strongly correlated materials. So far, mostly the relation between strain and resistivity, the so called elastoresistivity, has been investigated. The elastocaloric effect is a second rank tensor quantity describing the relation between entropy and strain. In contrast to the elastoresistivity, the elastocaloric effect is a thermodynamic quantity. Experimentally, elastocaloric effect measurements are demanding since the thermodynamic conditions during the measurement have to be well controlled. Here we present a technique to measure the elastocaloric effect under quasi adiabatic conditions. The technique is based on oscillating strain, which allows for increasing the frequency of the elastocaloric effect above the thermal relaxation rate of the sample. We apply the technique to Co-doped iron pnictide superconductors and show that the thermodynamic signatures of second order phase transitions in the elastocaloric effect closely follow those observed in calorimetry experiments. In contrast to the heat capacity, the electronic signatures in the elastocaloric effect are measured against a small phononic background even at high temperatures, establishing this technique as a powerful complimentary tool for extracting the entropy landscape proximate to a continuous phase transition.

description: Hallmarking is a vital certification of gold purity, which significantly creates the confidence of consumers and purchasing behavior. This study examines the impact of the characteristics on the decision to buy women for gold jewelry in Karnataka focusing on key factors such as trust, price perception, quality, social influence and level of awareness. The structured quantitative survey was carried out in 400 women from Bengalur, Mysur, Hubballi and Mangaluru, using statistical techniques such as regression tests. The finding suggests that the characteristics increase consumer confidence and perceived quality and strengthen its role in deciding on purchase. However, the gaps persist, especially in radius and rural areas, which affects the adoption rate. Sensitivity to the price and reputation of the brand continues to influence consumers' choice. This study provides valuable knowledge of consumer behavior and recommends targeted campaigns to raise awareness, retailers' incentives and political interventions to strengthen adoption and promotion of ethical gold trade in India.

description: We present a new, fast, algorithm for the separation of astrophysical components superposed in maps of the sky, based on the fast Independent Component Analysis technique (FastICA). It allows to recover both the spatial pattern and the frequency scalings of the emissions from statistically independent astrophysical processes, present along the line-of-sight, from multi-frequency observations. We apply FastICA to simulated observations of the microwave sky with angular resolution and instrumental noise at the mean nominal levels for the Planck satellite, containing the most important known diffuse signals: the Cosmic Microwave Background (CMB), Galactic synchrotron, dust and free-free emissions. A method for calibrating the reconstructed maps of each component at each frequency has been devised. The spatial pattern of all the components have been recovered on all scales probed by the instrument. In particular, the CMB angular power spectra is recovered at the percent level up to $\ell_{max}\simeq 2000$. Frequency scalings and normalization have been recovered with better than percent precision for all the components at frequencies and in sky regions where their signal-to-noise ratio exceeds 1.5; the error increases at ten percent level for signal-to-noise ratios about 1. Runs have been performed on a Pentium III 600 MHz computer; FastICA typically took a time of the order of 10 minutes for all-sky simulations with 3.5 arcminutes pixel size. We conclude that FastICA is an extremly promising technique for analyzing the maps that will be obtained by the forthcoming high resolution CMB experiments.

Density waves in the shearing sheet III. Disc heating

Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The problem of dynamical heating of galactic discs by spiral density waves is discussed using the shearing sheet model. The secular evolution of the disc is described quantitatively by a diffusion equation for the distribution function of stars in the space spanned by integrals of motion of the stars, in particular the radial action integral and an integral related to the angular momentum. Specifically, disc heating by a succession of transient, `swing amplified' density waves is studied. It is shown that such density waves lead predominantly to diffusion of stars in radial action space. The stochastical changes of angular momenta of the stars and the corresponding stochastic changes of the guiding centre radii of the stellar orbits induced by this process are much smaller.

 Remarks. The speci®c status of P. pajarella Barnard, 1967 is uncertain, as its description was based upon a single immature (only 2.1 mm) specimen. Phippsiella pajarella can, at present, best be distinguished from its congeners by the unhooked setae on the outer plate of maxilla 2. Otherwise, its immature characteristics of e.g. the short and weakly articulate antennae, and the weakly setose pereopods make it di cult to distinguish from immature specimens of other Phippsiella spp.
 Type material of P. cascadiensis has been examined, and some important diOEerences with the original description were revealed (see below).

description: We report a joint experimental and theoretical study of the structural, vibrational, and electronic properties of layered monoclinic arsenic sulfide (alpha-As2S3), aka mineral orpiment, under compression. X-ray diffraction and Raman scattering measurements performed in orpiment samples at high pressure and combined with ab initio calculations have allowed us to determine the equation of state and the tentative assignment of the symmetry of many Raman-active modes of orpiment. From our results, we conclude that no first-order phase transition occurs up to 25 GPa at room temperature; however, compression leads to an isostructural phase transition above 20 GPa. In fact, As coordination increases from threefold at room pressure to more than fivefold above 20 GPa. This increase in coordination can be understood as the formation of metavalent bonding at high pressure, which results in a progressive decrease of the electronic and optical bandgap, an increase of the dielectric tensor and Born effective charges, and a considerable softening of many high-frequency optical modes with pressure. The formation of metavalent bonding may also explain the behavior of other group-15 sesquichalcogenides under compression. Moreover, our results suggest that group-15 sesquichalcogenides either show metavalent bonding at room pressure or undergo a transition from p-type covalent bonding at room pressure towards metavalent bonding at high pressure, as a preceding phase towards metallic bonding at very high pressure.

description: The solver DICOPT is based on the outer-approximation algorithm used for solving mixed-integer nonlinear programming (MINLP) problems. This algorithm is very effective for solving some types of convex MINLPs. However, it has been observed that DICOPT has difficulties solving instances in which some of the nonlinear constraints are so restrictive that nonlinear subproblems generated by the algorithm are infeasible. This problem is addressed in this paper with a feasibility pump algorithm, which modifies the objective function in order to efficiently find feasible solutions. It has been implemented as a preprocessing algorithm, which is used to initialize both the incumbent and the mixed-integer linear relaxation of the outer-approximation algorithm. Computational comparisons with previous versions of DICOPT on a set of convex MINLPs demonstrate the effectiveness of the proposed algorithm in terms of solution quality and solution time.

description: Strategies to empower women in development contexts frequently address their authority to take decisions within their household, including decisions that are taken jointly by couples. Assessing empowerment in joint decision-making has traditionally followed a dichotomous approach: decisions are either joint or not, with the former associated with women’s empowerment. This paper contributes to a more nuanced understanding of the empowerment effects of joint decision-making, based on case study data from Uganda. We present survey data revealing significant gender differences in perception of decision-making over the adoption of agricultural practices and consumption expenses. Women reported joint decision-making more often than men, who presented themselves more as sole decision makers. We supplement the survey data with an in-depth study in Lodi village, where we reconstruct meanings attached to joint decision-making using focus group discussions, a decision-making game and participant observation. Reported joint decision-making included a range of practices from no conversation among partners to conversations where female spouse’s ideas are considered but the man has the final say. The findings suggest that local interpretations of joint decision-making, in at least this case of a dominantly patriarchal context, can limit its potential for assessing women’s empowerment.

description: Trematurella Trägårdh, 1942: 111.
 Type species Trematurella stylifera Trägårdh, 1942: 111, by monotypy.
 Diagnosis — Medium size mites, highly sclerotized, with characteristic sculpture. The idiosoma is oval and flat at the dorsal part. The unique characteristics of this species: the large dorsal shield is surrounded by a rather narrow marginal shield. The dorsal setae are serrated, very long and massive, of the same width at the whole length. The female genital shield is large, wide at the base and becomes more and more narrow towards the front (the shape resembles the foot of the iron), with a long narrow appendix at the front, intensively sculptured. The male genital shield is oval, smooth and has no paragenital setae. They have five pairs of sternal setae, two pairs of adanal setae Ad (1-Ad2), and single postanal seta Pa (). There are cavities for the leg hiding, the last ones, hiding the fourth pair of legs, are located across and do not overlap with the opisthosoma. At the first pair of tarsus there is a single claw. The first pair of hypostomal setae (h1) is needle-shaped and smooth, the other ones h2-h (4) are feather-like.
Also the setae at the trochanters of palps are feather-like.

On some information geometric structures concerning Mercator projections
Creators: name: Wada, Tatsuaki
Publisher: name: arXiv
Year: 2019
Subjects: subject: General Mathematics (math.GM)

description: Some information geometric structures concerning the Mercator projections are studied. It is known that a loxodrome on the surface of the globe is related to the straight line on a Mercator map by the Mercator projection. It is not well known that an affine connection with torsion plays a fundamental role to describe an auto-parallel path on the surface. Based on these information geometric structures, Gauss distribution is reconsidered from the view point of the affine connection with a torsion. Some relations with deformed functions are also pointed out.

description: We undertake a critical evaluation of recent observational information on $Ω_m$ and $Ω_Λ$ in order to identify possible sources of systematic errors and effects of simplified statistical analyses. We combine observations for which the results have been published in the form of likelihood contours in the $Ω_m ,Ω_Λ$ plane. We approximate the contours by fifth order polynomials, and we then use the maximum likelihood method to obtain joint likelihood contours for the combined data. In the choice of statistical merits we aim at minimum loss of information rather than at minimum variance. We find that $Ω_0 = Ω_m + Ω_Λ= 0.99\pm 0.04 \pm 0.03$, where the first error is mainly statistical and the second error is systematical. In a flat Universe we find $Ω_m^{flat} = 0.31 \pm 0.04 \pm 0.04$.

description: Benzimidazolium salts (1a and 1b) and respective palladium complexes (2a and 2b) were prepared and characterized with 1H and 13C NMR, IR, elemental analysis as well as HRMS (for 2a). All target compounds were screened as potential anticancer agents against human cell lines for assessing their cytotoxicity. Heterocyclic organic compounds (1a and 1b) showed more cytotoxic activity than their complexes (2a and 2b) in the tested two cell lines. Particularly, a benzimidazolium salt including a 4-methylbenzyl group had a high cytotoxic potency towards MDA-MB-231 and DLD-1 cell lines with IC50 values comparable to a well-known anticancer drug cisplatin, which is generally used in clinical studies. Furthermore, a compound namely 1-(2-hydroxyethyl)-3-(2,3,4,5,6-pentamethylbenzyl)-1H-benzo[d]imidazol-3-ium bromide was found to be more cytotoxic activity in MDA-MB-231 cell line compared to cisplatin with following IC50 value of 7.59 ± 0.68 μM.

description: Social networks are quickly becoming the primary medium for discussing what is happening around real-world events. The information that is generated on social platforms like Twitter can produce rich data streams for immediate insights into ongoing matters and the conversations around them. To tackle the problem of event detection, we model events as a list of clusters of trending entities over time. We describe a real-time system for discovering events that is modular in design and novel in scale and speed: it applies clustering on a large stream with millions of entities per minute and produces a dynamically updated set of events. In order to assess clustering methodologies, we build an evaluation dataset derived from a snapshot of the full Twitter Firehose and propose novel metrics for measuring clustering quality. Through experiments and system profiling, we highlight key results from the offline and online pipelines. Finally, we visualize a high profile event on Twitter to show the importance of modeling the evolution of events, especially those detected from social data streams.

description: Given a large network, local community detection aims at finding the community that contains a set of query nodes and also maximises (minimises) a goodness metric. Furthermore, due to the inconvenience or impossibility of obtaining the complete network information in many situations, the detection becomes more challenging. This problem has recently drawn intense research interest. Various goodness metrics have been proposed. And most of them base on the statistical features of community structures, such as the internal density or external spareness. However, the metrics often result in unsatisfactory results by either including irrelevant subgraphs of high density, or pulling in outliers which accidentally match the metric for the time being. Further more, when in a highly overlapping environment such as social networks, the unconventional community structures make these metrics usually end up with a quite trivial detection result. In our work, we go for a alternative point of view on the formation of the communities, namely the assembly of nodes with different roles in the structure. With the new view point, we present two metrics which are proved to perform superiorly in traditional and complex environment respectively. Moreover, on realising a single metric is whatsoever limited in effectiveness as well as scope of application, we raise up a complete framework for the collaboration ofmetrics in the field, which also lands a base-stone for future innovations. The experiment results collected from Amazon, DBLP, Youtube and LivingJournal well certifies the effectiveness of the metrics.

description: The structural and dynamical properties of water confined in nanoporous silica with a pore diameter of 2.7 nm were investigated by performing large-scale molecular dynamics simulations using the reactive force field. The radial distribution function and diffusion coefficient of water were calculated, and the values at the center of the pore agreed well with experimental values for real water. In addition, the pore was divided into thin coaxial layers, and the average number of hydrogen bonds, hydrogen bond lifetime, and hydrogen bond strength were calculated as a function of the radial distance from the pore central axis. The analysis showed that hydrogen bonds involving silanol (Si-OH) have a longer lifetime, although the average number of hydrogen bonds per atom does not change from that at the pore center. The longer lifetime, as well as smaller diffusion coefficient, of these hydrogen bonds is attributed to their greater strength.
The efficiency and effectiveness of income transfer systems : a comparative study using microdata
Creators: name: Mitchell, Deborah
Publisher: name: The Australian National University
Year: 1990
Subjects: subject: Income maintenance programs
subject: Public welfare

description: This study uses the microdata assembled by the Luxembourg Income Study (LIS) to examine the impact of the social security and taxation systems on poverty and inequality in ten OECD countries, circa 1980. A model of income transfer processes is developed to show the relationship between government expenditure, transfer instruments and the outcomes of the transfer process. The study adapts and extends existing methodologies in the poverty and inequality literature. These measures are then applied to the LIS microdata to reveal the efficiency and effectiveness of both the social security and taxation systems in the countries chosen for comparison. The analysis shows that, in general, it is the larger welfare states which are the most effective in reducing poverty and inequality. The most efficient welfare states are those which apply either income tests to direct transfers and/or have highly progressive taxation systems. There appears to be a trade-off between the efficiency and effectiveness goals of the transfer systems in the LIS countries. The findings of the empirical analysis are contrasted with several streams of the welfare state literature to examine the degree of correspondence between theory and 'real-world' outcomes. The study shows that many of the conventional wisdoms of the welfare state literature do not hold empirically. This is attributed to the lack of attention to the role of taxation, expenditure efficiency and the incidence of transfers among the pre-transfer poor population.
Exhaustive Exact String Matching: The Analysis of the Full Human Genome

description: Exact string matching has been a fundamental problem in computer science for decades because of many practical applications. Some are related to common procedures, such as searching in files and text editors, or, more recently, to more advanced problems such as pattern detection in Artificial Intelligence and Bioinformatics. Tens of algorithms and methodologies have been developed for pattern matching and several programming languages, packages, applications and online systems exist that can perform exact string matching in biological sequences. These techniques, however, are limited to searching for specific and predefined strings in a sequence. In this paper a novel methodology (called Ex2SM) is presented, which is a pipeline of execution of advanced data structures and algorithms, explicitly designed for text mining, that can detect every possible repeated string in multivariate biological sequences. In contrast to known algorithms in literature, the methodology presented here is string agnostic, i.e., it does not require an input string to search for it, rather it can detect every string that exists at least twice, regardless of its attributes such as length, frequency, alphabet, overlapping etc. The complexity of the problem solved and the potential of the proposed methodology is demonstrated with the experimental analysis performed on the entire human genome. More specifically, all repeated strings with a length of up to 50 characters have been detected, an achievement which is practically impossible using other algorithms due to the exponential number of possible permutations of such long strings.
