description: Based on high-resolution optical spectroscopy in the blue and the near infra-red spectral range, we derived velocity images (Doppler tomograms) of the mass-donating secondary star and the accretion stream of the long-period eclipsing polar V1309 Ori (RX J0515.41+0104.6). Combined with HST-spectroscopy of high time resolution and optical photometry we were able to derive the main system parameters and to determine the accretion geometry of the binary. The length of the eclipse of the white dwarf is Delta t_{ecl} = 2418 +/- 60 s, the mass ratio Q = 1.37 - 1.63, and the orbital inclination i=76.6 - 78.9 degrees. The surface of the secondary star could be resolved in the Doppler image of NaI absorption lines, where it shows a marked depletion on the X-ray irradiated side. The accretion geometry proposed by us with a nearly aligned rotator, co-latitude delta ~ 10 degrees, tilted away from the ballistic stream, azimuth chi ~ -35 degrees, explains the shape of the emission-line Doppler tomograms and the shape of optical/UV eclipse light curves.

description: Typicality has drawn considerable interest among academics and practitioners and has been employed by fashion companies seeking to increase consumer interest in ‘basic' products. However, limited research on typicality focuses on apparel products, as most studies on this property have focused on other consumer products (e.g. chairs). Based on preference-for-prototype and categorisation theories, the purpose of this study was to investigate consumer perceptions of typicality as an aesthetic property of apparel products. This mixed-methods research identified the mental images consumers have as the prototypes of the apparel categories of pants, jackets, and shirts. This study contributes to the aesthetics, clothing and textiles, and product design literatures by offering insights into the aesthetic property of typicality from the perspective of the consumer. Findings guide apparel brands seeking to further incorporate the aesthetic concept of typicality into their product designs.

description: Stencil loops are a common motif in computations including convolutional neural networks, structured-mesh solvers for partial differential equations, and image processing. Stencil loops are easy to parallelise, and their fast execution is aided by compilers, libraries, and domain-specific languages. Reverse-mode automatic differentiation, also known as algorithmic differentiation, autodiff, adjoint differentiation, or back-propagation, is sometimes used to obtain gradients of programs that contain stencil loops. Unfortunately, conventional automatic differentiation results in a memory access pattern that is not stencil-like and not easily parallelisable. In this paper we present a novel combination of automatic differentiation and loop transformations that preserves the structure and memory access pattern of stencil loops, while computing fully consistent derivatives. The generated loops can be parallelised and optimised for performance in the same way and using the same tools as the original computation. We have implemented this new technique in the Python tool PerforAD, which we release with this paper along with test cases derived from seismic imaging and computational fluid dynamics applications.

description: V838 Mon is marking one of the most mysterious stellar outbursts on record. The spectral energy distribution of the progenitor resembles an under-luminous F main sequence star (at V=15.6 mag), that erupted into a cool supergiant following a complex and multi-maxima lightcurve (peaking at V=6.7 mag). The outburst spectrum show BaII, LiI and lines of several s-elements, with wide P-Cyg profiles and a moderate and retracing emission in the Balmer lines. A light-echo discovered expanding around the object helped to constrain the distance (d=790+/-30 pc), providing M_V=+4.45 in quiescence and M_V=-4.35 at optical maximum (somewhat dependent on the still uncertain E(B-V)=0.5 reddening). The general outburst trend is toward lower temperatures and larger luminosities, and continuing so at the time of writing. The object properties conflict with a classification within already existing categories: the progenitor was not on a post-AGB track and thus the similarities with the born-again AGB stars FG Sge, V605 Aql and Sakurai's object are limited to the cool giant spectrum at maximum; the cool spectrum, the moderate wind velocity (500 km/sec and progressively reducing) and the monotonic decreasing of the low ionization condition argues against a classical nova scenario. The closest similarity is with a star that erupted into an M-type supergiant discovered in M31 by Rich et al. (1989), that became however much brighter by peaking at M_V=-9.95, and with V4332 Sgr that too erupted into an M-type giant (Martini et al. 1999) and that attained a lower luminosity, closer to that of V838 Mon. M31-RedVar, V4332 Sgr and V838 Mon could be manifestations of the same and new class of astronomical objects.

description: The evolution of contact binary star systems in mass asymmetry (transfer) coordinate is considered. The orbital period changes is explained by an evolution in mass asymmetry towards the symmetry (symmetrization of binary system). It is predicted that a decreasing and an increasing orbital periods are related, respectively, with the non-overlapping and overlapping stage of the binary star during its symmetrization. A huge amount of energy $ΔU\approx 10^{41}$ J is converted from the potential energy into internal energy of the stars during the symmetrization. As shown, the merger of stars in the binary systems, including KIC 9832227, is energetically an unfavorable process. The sensitivity of the calculated results to the values of total mass and orbital angular momentum is analyzed.

description: A collaborative study was conducted to understand the correlation between pigments purity profile (primary aromatic amine content of the pigments) and the behaviour of these PAAs during cold water extraction (CWE) tests according to EN 645. From a selection of organic pigments based on seven colour indexes (PR122, PR184, PO13, PY74, PY111, PY138 and PY155), the pigment purity profile was established according to European Resolution AP (89) 1, then mono-pigmented inks were prepared and napkins printed with these inks. In a second step, cold water extraction and PAA determination were performed by two independent laboratories. In one laboratory, an analytical method based on LC-MS/MS was used, whereas in the other laboratory a method based on LC-HRMS using Orbitrap technology was developed for the simultaneous analysis of 35 PAAs. Good qualitative results were obtained if we consider that at significant levels the PAAs were positively detected in both laboratories, except for 3-amino-4-methoxybenzanilide and 8-amino-2-methyl-quinoline, for which inter-laboratory differences were observed. It was also shown that no contamination from unexpected PAAs was detected. The comparison between pigment analysis and CWE results shows that if the pigment purity profile is of major importance, other parameters such as pigment surface treatment, ink grinding process or ink formulation could have an important influence on the CWE results. For such sensitive applications, for example napkins or other Food Contact Materials (FCM), it is therefore recommended not only to select a pigment with a good purity profile but also to test the pigment in the final application. Finally, this work highlights the difficulty of validating a product on a single analysis and shows the importance of a multilevel global assessment on worst case application.

description: The sEEnergies project is based on the concept of Energy Efficiency First Principle and is aimed at the identification of energy efficiency potentials on which the future European energy system should be designed. In two earlier deliverables (D2.1 and D2.3), the energy savings of the Energy-efficiency scenario compared to a business-as-usual trajectory have been assessed. The present deliverable, D2.4, discusses additional environmental and social impacts of the measures included in the Energy-efficiency scenario. For each impact category, the causal mechanisms producing the impact are briefly described. For some of the impacts, quantitative assessments of the impacts compared to a business-as-usual trajectory have also been made. However, for most impact categories, only qualitative descriptions have been possible.
Interaction-dependent anisotropy of fractional quantum Hall states

description: A fractional quantum Hall (FQH) system with broken rotational symmetry exploits its geometric degree of freedom to minimize its ground state energy. The mass anisotropy of bare particles interacting isotropically is partially inherited by the many-body FQH state, and the extent to which it does so depends on the type of interaction, filling fraction and ground state phase. Using numerical infinite density matrix renormalization group simulations, we investigate the transference of elliptical ($C_2$-symmetric) anisotropy from the band mass of the bare particles to the FQH states, for various power law interactions. We map out the response of FQH states to small anisotropy as a function of power law exponent, filling, and statistics (bosonic or fermionic) of the constituents. Interestingly, we find a non-analyticity in the linear response of the FQH state at a special filling-dependent value of the power law exponent, above which the interaction effectively becomes zero-range (point-like). We also investigate the the effect of $C_4$-symmetric band distortions, where we observe a strikingly different dependence on filling.

description: We theoretically investigate the noise of a single-electron transistor in the regime of large quantum fluctuation of charge out of equilibrium. We show that the charge noise is suppressed due to the charge renormalization caused by the quantum fluctuation. However the fluctuation is not strong enough to wash out the charge quantization. We find that the renormalization effect reduces the performance of a single-electron electrometer.

We study expressions of the form \[ \sum_{k \text{mod} a} \prod_{j=1}^d \cot^{(m_j)} π(\frac{k a_j}{a} + z_j ) . \] Here the sum is taken over all k mod a for which the summand is not singular. These Dedekind cotangent sums generalize and unify various arithmetic sums introduced by Dedekind, Rademacher, Apostol, Carlitz, Zagier, Berndt, Meyer, Sczech, and Dieter. Generalized Dedekind sums appear in various areas such as analytic and algebraic number theory, topology, algebraic and combinatorial geometry, and algorithmic complexity. We prove reciprocity laws, Petersson-Knopp identities, and computability statements for the Dedekind cotangent sums.

description: Unsupervised near-duplicate detection has many practical applications ranging from social media analysis and web-scale retrieval, to digital image forensics. It entails running a threshold-limited query on a set of descriptors extracted from the images, with the goal of identifying all possible near-duplicates, while limiting the false positives due to visually similar images. Since the rate of false alarms grows with the dataset size, a very high specificity is thus required, up to $1 - 10^{-9}$ for realistic use cases; this important requirement, however, is often overlooked in literature. In recent years, descriptors based on deep convolutional neural networks have matched or surpassed traditional feature extraction methods in content-based image retrieval tasks. To the best of our knowledge, ours is the first attempt to establish the performance range of deep learning-based descriptors for unsupervised near-duplicate detection on a range of datasets, encompassing a broad spectrum of near-duplicate definitions. We leverage both established and new benchmarks, such as the Mir-Flick Near-Duplicate (MFND) dataset, in which a known ground truth is provided for all possible pairs over a general, large scale image collection. To compare the specificity of different descriptors, we reduce the problem of unsupervised detection to that of binary classification of near-duplicate vs. not-near-duplicate images. The latter can be conveniently characterized using Receiver Operating Curve (ROC). Our findings in general favor the choice of fine-tuning deep convolutional networks, as opposed to using off-the-shelf features, but differences at high specificity settings depend on the dataset and are often small. The best performance was observed on the MFND benchmark, achieving 96\% sensitivity at a false positive rate of $1.43 \times 10^{-6}$.

Three-Dimensional Magnetohydrodynamic Simulations of Spherical Accretion

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

description: We present three-dimensional numerical magnetohydrodynamic simulations of radiatively inefficient spherical accretion onto a black hole. The simulations are initialized with a Bondi flow, and with a weak, dynamically unimportant, large-scale magnetic field. The magnetic field is amplified as the gas flows in. When the magnetic pressure approaches equipartition with the gas pressure, the field begins to reconnect and the gas is heated up. The heated gas is buoyant and moves outward, causing line stretching of the frozen-in magnetic field. This leads to further reconnection, and more heating and buoyancy-induced motions, so that the flow makes a transition to a state of self-sustained convection. The radial structure of the flow changes dramatically from its initial Bondi profile, and the mass accretion rate onto the black hole decreases significantly. Motivated by the numerical results, we develop a simplified analytical model of a radiatively inefficient spherical flow in which convective transport of energy to large radii plays an important role. In this "convection-dominated Bondi flow" the accretion velocity is highly subsonic and the density varies with radius as ~R^{-1/2} rather than the standard Bondi scaling ~R^{-3/2}. We estimate that the mass accretion rate onto the black hole is significantly less than the Bondi accretion rate. Convection-dominated Bondi flows may be relevant for understanding many astrophysical phenomena, e.g. post-supernova fallback and radiatively inefficient accretion onto supermassive black holes, stellar-mass black holes and neutron stars.

description: The Masters Hypothesis is the claim that unprecedented buying pressure in recent years from commodity index investors created massive bubbles in food and energy prices. A number of recent studies investigate the empirical relationship between index investment and price movements in agricultural futures markets. One line of research uses time-series regression tests, such as Granger causality tests, to investigate the relationship between price movements and index positions. This research provides little evidence in support of the Masters Hypothesis in agricultural futures markets. A second line of research uses cross-sectional regression tests and studies in this area provide very limited evidence in favor of the Masters Hypothesis for agricultural futures markets. A third line of research investigates whether there is a significant relationship between commodity index trading and the difference, or spread, between futures prices of different contract maturities. These studies report a range of results depending on the type of test. However, the bulk of the evidence indicates either no relationship or a negative relationship, which is once again inconsistent with the Masters Hypothesis. Overall, this growing body of literature fails to find compelling evidence that buying pressure from commodity index investment in recent years caused a massive bubble in agricultural futures prices. The Masters Hypothesis is simply not a valid characterization of reality.

 Type species Sphex nigerrima Scopoli, 1763, designated by ICZN (1973).
 Remarks. This is one of the most species-rich genera in Pompilinae. It has a cosmopolitan distribution with six subgenera found in the Neotropics (Evans 1966). Four of these (Anoplius Dufour, 1834, Arachnophroctonus Howard, 1901, and Notiochares Banks, 1917) have been reported for the Dominican Republic (Wasbauer & Kimsey 1985; Evans 1966; Snelling & Torres 2004). Except for Anoplius, these subgenera have a tarsal comb, and each has a single species record from the Dominican Republic.

description: We present a Catalog of high proper motion (HPM) stars detected in the foreground of central parts of the Magellanic Clouds. The Catalog contains 2161 objects in the 4.5 square degree area towards the LMC, and 892 HPM stars in the 2.4 square degree area towards the SMC. The Catalog is based on observations collected during four years of the OGLE-II microlensing survey. The Difference Image Analysis (DIA) of the images provided candidate HPM stars with proper motion as small as 4 mas/yr. These appeared as pseudo-variables, and were all measured astrometrically on all CCD images, providing typically about 400 data points per star. The reference frame was defined by the majority of background stars, most of them members of the Magellanic Clouds. The reflex motion due to solar velocity with respect to the local standards of rest is clearly seen. The largest proper motion in our sample is 363 mas/yr. Parallaxes were measured with errors smaller than 20% for several stars.

 Delacampius hirtus: STEHLÍK & KERZHNER (1999): 122 (generic placement); CASSIS & GROSS (2002): 625 (catalogue, distribution, ecology).
 Type material examined. HOLOTYPE: ♀, AUSTRALIA: NORTHERN TERRITORY: Darwin (BMNH).
 Taxonomic note. Reexamination of the holotype revealed that this species does not belong to the genus Delacampius, but to Tauberella Schmidt, 1932, sharing the following essential characters of the latter genus: callar lobe distinctly hairy and strongly gibbous with ornamental impressions, and strongly constricted basally compared with the pronotal lobe; the latter without lateral margins. Thus, we establish the following new combination: Tauberella hirta (Blöte, 1933) comb. nov.
 Comparative note. CASSIS & GROSS (2002) mentioned that Delacampius hirtus also occurs in New Guinea. However, the New Guinea Tauberella belongs to another species, T. papuensis Schmidt, 1932. Both species differ in the following characters: T. papuensis (Fig. 23) has the corium blackish brown except the costal margin, the adjacent part of the corial cleft and a narrow stripe parallel with the apical margin of the corium pale, impressions on the callar lobe are more distinct, and the pubescence slightly shorter than in T. hirta. In T. hirta (Fig. 22), the corium is pale with the median black spot coalescent with the black stripe running along the claval suture.
 Distribution. Australia, Northern Territory (BLÖTE 1933, CASSIS & GROSS 2002).

description: A QuEChERS multi-residue GC-MS/MS method was developed for determining 160 pesticides in fresh edible snails. The method was validated according to the EU guidance SANTE/12682/2019. Twenty-seven different pesticides were quantified in the 824 samples analysed. Of these, 22.09% contained pesticide residues; in one case six different pesticides. The most frequently quantified pesticides were chlorpyrifos (108 samples), cypermethrin (50), difenoconazole (24), oxyfluorfen (13), lambda-cyhalothrin (12), tetraconazole and azoxystrobin (7). Other pesticides were found in <5 samples. Of the samples containing residues, 154 exceeded the EU legal limit. However, the estimated daily intake of pesticide residues showed that snail consumption does not represent appreciable risks to consumer health.

description: Silver (E174) is authorised as a food additive in the EU. The unknown particle size distribution of E174 is a specific concern for the E174 risk assessment. This study characterised the fraction of silver (nano)particles in 10 commercially available pristine E174 food additives and 10 E174-containing products by transmission electron microscopy (TEM) and single-particle inductively coupled plasma-mass spectrometry (spICP-MS). TEM analysis showed that all samples contained micrometre-sized flakes and also a fraction of (nano)particles. Energy-dispersive X-ray spectroscopy (EDX) and electron diffraction confirmed that the (nano)particles and micrometre-sized flakes consisted of silver. A higher amount of (nano)particles was observed in the products than in the food additives. In addition, the surface of the micrometre-sized flakes was rougher in products. The median of the minimum external dimension, assessed as minimal Feret diameter, of the fraction of (nano)particles determined by quantitative TEM analysis was 11 ± 4 nm and 18 ± 7 nm (overall mean ± standard deviation), for food additives and products, respectively. Similar size distributions were obtained by spICP-MS and TEM, considering the limit of detection of spICP-MS. The median of the equivalent spherical diameter of the fraction of (nano)particles determined by spICP-MS was 19 ± 4 nm and 21 ± 2 nm (overall mean ± standard deviation), for food additives and products, respectively. In all samples, independent of the choice of technique, the nano-sized particles represented more than 97% (by number) of the silver particles, even though the largest mass of silver was present as flakes.

description: Multispectral person detection aims at automatically localizing humans in images that consist of multiple spectral bands. Usually, the visual-optical (VIS) and the thermal infrared (IR) spectra are combined to achieve higher robustness for person detection especially in insufficiently illuminated scenes. This paper focuses on analyzing existing detection approaches for their generalization ability. Generalization is a key feature for machine learning based detection algorithms that are supposed to perform well across different datasets. Inspired by recent literature regarding person detection in the VIS spectrum, we perform a cross-validation study to empirically determine the most promising dataset to train a well-generalizing detector. Therefore, we pick one reference Deep Convolutional Neural Network (DCNN) architecture and three different multispectral datasets. The Region Proposal Network (RPN) originally introduced for object detection within the popular Faster R-CNN is chosen as a reference DCNN. The reason is that a stand-alone RPN is able to serve as a competitive detector for two-class problems such as person detection. Furthermore, current state-of-the-art approaches initially apply an RPN followed by individual classifiers. The three considered datasets are the KAIST Multispectral Pedestrian Benchmark including recently published improved annotations for training and testing, the Tokyo Multi-spectral Semantic Segmentation dataset, and the OSU Color-Thermal dataset including recently released annotations. The experimental results show that the KAIST Multispectral Pedestrian Benchmark with its improved annotations provides the best basis to train a DCNN with good generalization ability compared to the other two multispectral datasets. On average, this detection model achieves a log-average Miss Rate (MR) of 29.74 % evaluated on the reasonable test subsets of the three datasets.

description: We used a thermodynamic integration scheme, which is specifically designed for disordered systems, to compute the interfacial free energy of the solid-liquid interface in the hard-sphere model. We separated the bulk contribution to the total free energy from the interface contribution, performed a finite-size scaling analysis and obtained for the (100)-interface $γ=0.591(11)k_{B}Tσ^{-2}$.

description: Making use of a unique tenant-landlord matched data from the Tigray region of Ethiopia, we are able to show how strategic response of tenants - to varying economic and tenure security status of the landlords - is important in explaining productivity differentials of sharecroppers. The results show that sharecroppers’ yield are significantly lower on plots leased from landlords who are non-kin; female; with lower income generating opportunity; and tenure insecure households, than on plots leased from landlords with contrasting characteristics. While, on aggregate, the result shows no significant efficiency loss on kin-operated sharecropped plots, a more decomposed analyses indicate strong evidences of Marshallian inefficiency on kin-operated plots leased from landlords with weaker bargaining power and higher tenure insecurity. This study, thus, shows how failure to control for such heterogeneity of landowners' characteristics can explain the lack of clarity in the existing empirical literature on the extent of moral hazard problems in sharecropping contracts.

description: Robots and artificial machines have been captivating the public for centuries, depicted first as threats to humanity, then as subordinates and helpers. In the last decade, the booming exposure of humans to robots has fostered an increasing interest in soft robotics. By empowering robots with new physical properties, autonomous actuation, and sensing mechanisms, soft robots are making increasing impacts on areas such as health and medicine. At the same time, the public sympathy to robots is increasing. However, there is still a great need for innovation to push robotics towards more diverse applications. To overcome the major limitation of soft robots, which lies in their softness, strategies are being explored to combine the capabilities of soft robots with the performance of hard metallic ones by using composite materials in their structures. After reviewing the major specificities of hard and soft robots, paths to improve actuation speed, stress generation, self-sensing and actuation will be proposed. Innovations in controlling systems, modeling, and simulation that will be required to use composite materials in robotics will be discussed. Finally, based on recently developed examples, the elements needed to progress toward a new form of artificial life will be described.

description: This paper deals with prediction of transient instability on 132kV grid network from Afam to Port Harcourt mains injection substation in Nigeria by determining the dynamic response of the generators on the system during fault conditions using Trapezoidal numerical technique.  The network’s data collected from Transmission Company of Nigeria were used as input to perform transient stability simulation in Electrical Transient Analyzer Program (ETAP 19.1) environment, so as to investigate the differential change in generator rotor angles, change in generator bus voltage and frequency of the system. Numerical techniques were deployed with circuit breaker and relay time setting (0.00, 0.02, 0.04, 0.06, 0.08, 0.10, 0.12, 0.14, 0.16, and 0.18.0.2s), when balanced 3 phase fault was initiated with the aim of determining the critical clearing angle (CCA) and critical clearing time (CCT) of the transmission grid. The results obtained shows that Trapezoidal rule numerical technique is stable, accurate, has a fast response time of 0.02s, lower percentage error of 5.6% and a stable critical clearing angle of 35.480. The Trapezoidal rule numerical technique is better when used compared to modified Euler method in sustaining stability during transient disturbance to the network under investigation when in operation
