description: Spatially resolved continuum observations of planet-forming disks show prominent ring and gap structures in their dust distribution. However, the picture from gas observations is much less clear and constraints on the radial gas density structure (i.e. gas gaps) remain rare and uncertain. We want to investigate the importance of thermo-chemical processes for the interpretation of high-spatial-resolution gas observations of planet-forming disks and their impact on derived gas properties. We apply the radiation thermo-chemical disk code ProDiMo (PROtoplanetary DIsk MOdel) to model self-consistently the dust and gas disk of HD 163296, using the DSHARP gas and dust observations. With this model we investigate the impact of dust gaps and gas gaps, considering chemistry and heating/cooling processes, on the observables and the derived gas properties. We find distinct peaks in the radial line intensity profiles of the CO line data of HD 163296 at the location of the dust gaps. Our model indicates that those peaks are not only a consequence of a gas temperature increase within the gaps but are mainly caused by the absorption of line emission from the back side of the disk by the dust rings. For two of the three prominent dust gaps in HD 163296, we find that thermo-chemical effects are negligible for deriving density gradients via measurements of the rotation velocity. However, for the gap with the highest dust depletion, the temperature gradient can be dominant and needs to be considered to derive accurate gas density profiles. Self-consistent gas and dust thermo-chemical modelling in combination with high-quality observations of multiple molecules are necessary to accurately derive gas gap depths and shapes. This is crucial to determine the origin of gaps and rings in planet-forming disks and to improve the mass estimates of forming planets if they are the cause of the gap.

description: The grain boundary (GB) mobility relates GB velocity to the thermodynamic driving forces and is central to our understanding of microstructure evolution in polycrystals. Recent molecular dynamics (MD) and experimental studies have shown that the temperature-dependence of the GB mobility is much more varied than is commonly thought. GB mobility may increase, decrease, remain constant or show multiple peaks with increasing temperature. We propose a mechanistic model for GB migration, based on the formation and migration of line defects (disconnection) within the GB. We implement this model in a kinetic Monte Carlo and statistical mechanics framework; the results capture all of these observed temperature dependencies and are shown to be in quantitative agreement with each other and direct MD simulations of GB migration for a set of specific grain boundaries. Examination of the dependence of GB mobility on disconnection mode and temperature provides new insight into how GBs migrate in polycrystalline materials.

description: The area of organic products every day takes a bigger mature, it is an emergent market that needs to be regulated, which turns this scenario to a complicated adoption due to the lack of uniformity in its different areas such as cultivation, production, transformation and the different processes involved in the value chain of each commercialized products, the existing legislation demands to the producers to obtain different certifications to fulfill each one of the norms that exist in the different regulations in national and international markets. Nowadays, it has been established organic products markets in different parts of Mexico, which conform part of the expansion for production and commercialization of organic products, this contributes to the population to expand their knowledge about this topic, creating a consumerism culture and generating new post-materialist attitudes towards the environmental care. This work gives a real background of how is perceived the selling and consuming organic vegetables market, the knowledge of organic vegetables, the concepts and perceptions that population has about this topic, which is very important since it’s useful to detect opportunity and holding areas, as to give necessary information to take decisions and to implement or not to implement agribusiness, same ones dedicated to commercialization of organic products in Delicias, Chihuahua.
Orthocomplementation and compound systems

description: In their 1936 founding paper on quantum logic, Birkhoff and von Neumann postulated that the lattice describing the experimental propositions concerning a quantum system is orthocomplemented. We prove that this postulate fails for the lattice L_sep describing a compound system consisting of so called separated quantum systems. By separated we mean two systems prepared in different ``rooms'' of the lab, and before any interaction takes place. In that case the state of the compound system is necessarily a product state. As a consequence, Dirac's superposition principle fails, and therefore L_sep cannot satisfy all Piron's axioms. In previous works, assuming that L_sep is orthocomplemented, it was argued that L_sep is not orthomodular and fails to have the covering property. Here we prove that L_sep cannot admit and orthocomplementation. Moreover, we propose a natural model for L_sep which has the covering property.

description: A fault-tolerant quantum processor may be configured using stationary qubits interacting only with their nearest neighbours, but at the cost of significant overheads in physical qubits per logical qubit. Such overheads could be reduced by coherently transporting qubits across the chip, allowing connectivity beyond immediate neighbours. Here we demonstrate high-fidelity coherent transport of an electron spin qubit between quantum dots in isotopically-enriched silicon. We observe qubit precession in the inter-site tunnelling regime and assess the impact of qubit transport using Ramsey interferometry and quantum state tomography techniques. We report a polarization transfer fidelity of 99.97% and an average coherent transfer fidelity of 99.4%. Our results provide key elements for high-fidelity, on-chip quantum information distribution, as long envisaged, reinforcing the scaling prospects of silicon-based spin qubits.

description: A new nonlinear electromagnetic wave mode in a magnetized plasma is predicted. Its existence depends on the interaction of an intense circularly polarized electromagnetic wave with a plasma, where quantum electrodynamical photon--photon scattering is taken into account. This scattering gives rise to a new coupling between the matter and the radiation. Specifically, we consider an electron--positron plasma, and show that the propagation of the new mode is admitted. It could be of significance in pulsar magnetospheres, and result in energy transport between the pulsar poles.

description: Extending the definition of phase-space (Wigner) quantum projectors to thermodynamic ensembles usually results into an efficient platform for quantifying their elementary information content. Given the spectral decomposition profile of a thermalized quantum system, general expressions for the quantum purity quantifier, $\mathcal{P}(β)$, and for phase-space projectors related to the quantum fidelity, $\mathcal{F}(β)$, are explicitly derived in terms of an explicit correspondence with the related partition function, $\mathcal{Z}(β)$. Besides quantifying the storage of information capacity of thermodynamical ensembles, the tools here introduced extend the role of the partition function in expressing the quantum behavior of thermodynamic ensembles.

description: In a ferromagnet, an anomalous-Hall heat current, given by the off-diagonal Peltier term $α_{xy}$, accompanies the anomalous Hall current. By combining Nernst, thermopower and Hall experiments, we have measured how $α_{xy}$ varies with hole density and lifetime $τ$ in $\rm CuCr_2Se_{4-x}Br_x$. At low temperatures $T$, we find that $α_{xy}$ is independent of $τ$, consistent with anomalous-velocity theories. Its magnitude is fixed by a microscopic geometric area ${\cal A}\sim 34 \mathrmÅ^2$. Our results are incompatible with some models of the Nernst effect in ferromagnets.

description: Following the discovery of the Kondo effect the bulk transport and magnetic behavior of the dilute magnetic alloys have been successfully described. In the last fifteen years new directions have been developed as the study of the systems of reduced dimensions and the artificial atoms so called quantum dots. In this review the first subject is reviewed starting with the scanning tunneling microscope (STM) study of a single magnetic impurity. The next subject is the reduction of the amplitude of the Kondo effect in samples of reduced dimension which was explained by the surface magnetic anisotropy which blocks the motion of the integer spin nearby the surface. The electron dephasing and energy relaxation experiments are discussed with the possible explanation including the surface anisotropy, where the situation in cases of integer and half-integer spins is very different. Finally, the present situation of the theory of dynamical structural defects is briefly presented which may lead to two-channel Kondo behavior.

description: The present work assumed as main objective: knowing the production and the marketing of goat meat in a silvopastoral region of the Mixteca Poblana in Mexico. Fifteen Familiar Production Units (FPU) Goat in the study, two spaces known as markets (tianguis) and 12 sale points were used to commercialize goat meat; a structured poll was applied with 75 questions under four productive indicators. The first one concentrated goat FPU general data, the second one concentrated the goat identification and register, the third one concentrated in the goat meat market and commercialization information, and the forth one included production costs, prices/kg meat and saucer, and preference percentages goat meat consumed in the Mixteca region; through the sounding probe in situ method. Finally, it was applied descriptive statistics; using SPSS 10,0 package for Windows. In the results, it was found that 60% of the producers are located in a regime of small property, with 110 populations from 30 to goat/unit of silvopastoral production, 13% of the FPU sell their goats at local and regional market in $600.00, 60% sells in $800.00, 7% in $850.00 and 20% sell in $900.00. The production cost/animal was $ 121. 05, and its net benefit of $ 679.57. The preference of the 100% was for white barbecue, to a cost of $ 200.00/kg. In conclusion, the production and marketing of goat meat in silvopastoral conditions are an option to produce on low costs and to commercialize it like organic product as a future source, because feed costs are reduced with the potential forage tree-shrub type consumed by goats throughout the year.

description: We present a recent Chandra observation of the quiescent low-mass X-ray binary containing a neutron star, located in the globular cluster M30. We fit the thermal emission from the neutron star to extract its mass and radius. We find no evidence of flux variability between the two observations taken in 2001 and 2017, nor between individual 2017 observations, so we analyse them together to increase the signal to noise. We perform simultaneous spectral fits using standard light-element composition atmosphere models (hydrogen or helium), including absorption by the interstellar medium, correction for pile-up of X-ray photons on the detector, and a power-law for count excesses at high photon energy. Using a Markov-chain Monte Carlo approach, we extract mass and radius credible intervals for both chemical compositions of the atmosphere: $R_{\textrm{NS}}=7.94^{+0.76}_{-1.21}$ km and $M_{\textrm{NS}}<1.19$ M$_{\odot}$ assuming pure hydrogen, and $R_{\textrm{NS}}=10.50^{+2.88}_{-2.03}$ km and $M_{\textrm{NS}}<1.78$ M$_{\odot}$ for helium, where the uncertainties represent the 90% credible regions. For H, the small radius is difficult to reconcile with most current nuclear physics models (especially for nucleonic equations of state) and with other measurements of neutron star radii, with recent preferred values generally in the 11-14 km range. Whereas for He, the measured radius is consistent with this range. We discuss possible sources of systematic uncertainty that may result in an underestimation of the radius, identifying the presence of surface temperature inhomogeneities as the most relevant bias. According to this, we conclude that either the atmosphere is composed of He, or it is a H atmosphere with a significant contribution of hot spots to the observed radiation.

We present preliminary results of the analysis of the precise spatial orientation of 38 colonial churches located on the Canary Island of La Gomera (Spain). The sample suggests that, although several churches have a canonical orientation within the solar range, a large proportion of them follow a pattern of orientations that is compatible with the steep orography of the island and, therefore, contrasts with the prescriptions contained in the texts of the early Christian writers.

description: The mean-field study of the stripe phases of t-t'-U Hubbard model confirms formation of the "impurity" subbands of states localized on domain walls. For bond-aligned stripes it is shown that segments of the Fermi surfaces (FS) in antinodal and nodal directions correspond to the "impurity" band or to that delocalized over a whole antiferromagnet domain. This might explain the dichotomy between corresponding quasiparticles in La_{2-x}Sr_xCuO_4. The Fermi surface changes its topology at some doping depending on stripe width. Additional ordering at the domain walls should be supposed to accord the observed 1/8 anomaly and the stripe spacing. It is confirmed also that the diagonal stripes can provide the dielectric state at nonzero doping.

description: Bayesian neural Networks (BNNs) are a promising method of obtaining statistical uncertainties for neural network predictions but with a higher computational overhead which can limit their practical usage. This work explores the use of high performance computing with distributed training to address the challenges of training BNNs at scale. We present a performance and scalability comparison of training the VGG-16 and Resnet-18 models on a Cray-XC40 cluster. We demonstrate that network pruning can speed up inference without accuracy loss and provide an open source software package, {\it{BPrune}} to automate this pruning. For certain models we find that pruning up to 80\% of the network results in only a 7.0\% loss in accuracy. With the development of new hardware accelerators for Deep Learning, BNNs are of considerable interest for benchmarking performance. This analysis of training a BNN at scale outlines the limitations and benefits compared to a conventional neural network.
Step by step eigenvalue analysis with EMTP discrete time solutions
Creators: name: Hollman, Jorge Ariel
Publisher: name: University of British Columbia
Year: 2010

description: The present work introduces a methodology to obtain a discrete time state space representation of an electrical network using the nodal [ G ] matrix of the Electromagnetic Transients Program (EMTP) solution. This is the first time the connection between the EMTP nodal analysis solution and a corresponding state-space formulation is presented. Compared to conventional state space solutions, the nodal EMTP solution is computationally much more efficient. Compared to the phasor solutions used in transient stability analysis, the proposed approach captures a much wider range of eigenvalues and system operating states. A fundamental advantage of extracting the system eigenvalues directly from the EMTP solution is the ability of the EMTP to follow the characteristics of nonlinearities. The system’s trajectory can be accurately traced and the calculated eigenvalues and eigenvectors correctly represent the system’s instantaneous dynamics. In addition, the algorithm can be used as a tool to identify network partitioning subsystems suitable for real-time hybrid power system simulator environments, including the implementation of multi-time scale solutions. The proposed technique can be implemented as an extension to any EMTP-based simulator. Within our UBC research group, it is aimed at extending the capabilities of our real-time PC-cluster Object Virtual Network Integrator (OVNI) simulator.

description: Chromium selenide thin films were grown epitaxially on Al${_2}$O${_3}$(0001) and Si(111)-(7${\times}$7) substrates using molecular beam epitaxy (MBE). Sharp streaks in reflection high-energy electron diffraction and triangular structures in scanning tunneling microscopy indicate a flat smooth film growth along the c-axis, and is very similar to that from a hexagonal surface. X-ray diffraction pattern confirms the growth along the c-axis with c-axis lattice constant of 17.39 Å. The grown film is semiconducting, having a small band gap of about 0.034 eV, as calculated from the temperature dependent resistivity. Antiferromagnetic nature of the film with a Néel temperature of about 40 K is estimated from the magnetic exchange bias measurements. A larger out-of-plane exchange bias, along with a smaller in-plane exchange bias is observed below 40 K. Exchange bias training effects are analyzed based on different models and are observed to be following a modified power-law decay behavior.

description: Inclusive cross-sections for gluon jet production are studied numerically in the perturbative QCD pomeron model for central collisions of identical nuclei at high energies. Two forms for the inclusive cross-sections, with and without emission from the triple pomeron vertex, are compared. The difference was found to reduce to a numerical factor 0.8$÷$ 09 for momenta $k$ below the saturation momentum $Q_s$. Above $Q_s$ no difference was found at all. The gluon spectrum was found to be $\sim A$ for $kQ_s$. At large $k$ the spectrum falls as $1/k^{2.7÷3.3}$ flattening with energy. The multiplicities are proportional to $A$ with a good precision. Their values are high amd grow rapidly with energy.

description: The robust principal component analysis (RPCA) decomposes a data matrix into a low-rank part and a sparse part. There are mainly two types of algorithms for RPCA. The first type of algorithm applies regularization terms on the singular values of a matrix to obtain a low-rank matrix. However, calculating singular values can be very expensive for large matrices. The second type of algorithm replaces the low-rank matrix as the multiplication of two small matrices. They are faster than the first type because no singular value decomposition (SVD) is required. However, the rank of the low-rank matrix is required, and an accurate rank estimation is needed to obtain a reasonable solution. In this paper, we propose algorithms that combine both types. Our proposed algorithms require an upper bound of the rank and SVD on small matrices. First, they are faster than the first type because the cost of SVD on small matrices is negligible. Second, they are more robust than the second type because an upper bound of the rank instead of the exact rank is required. Furthermore, we apply the Gauss-Newton method to increase the speed of our algorithms. Numerical experiments show the better performance of our proposed algorithms.

Subjects: subject: Astrophysics (astro-ph)

description: Positions of High-Mass X-ray Binaries are often known precisely enough to unambiguously identify the optical component, and a number of those stars are monitored by the OGLE and MACHO collaborations. The light curves of two such candidates are examined for evidence of Be star behavior and for periodicity. One of the stars exhibits two periods of 6.833 and 15.586 hours, much shorter and more stable than periods of Be/X-Ray Binaries that are attributed to the Be star's disk, but consistent with short-term Be variability attributed to pulsations. The multiperiodicity is quantified with Fourier techniques and examined for phase stability; a combination of radial and non-radial pulsations is discussed.

description: Wikidata has grown to a knowledge graph with an impressive size. To date, it contains more than 17 billion triples collecting information about people, places, films, stars, publications, proteins, and many more. On the other side, most of the information on the Web is not published in highly structured data repositories like Wikidata, but rather as unstructured and semi-structured content, more concretely in HTML pages containing text and tables. Finding, monitoring, and organizing this data in a knowledge graph is requiring considerable work from human editors. The volume and complexity of the data make this task difficult and time-consuming. In this work, we present a framework that is able to identify and extract new facts that are published under multiple Web domains so that they can be proposed for validation by Wikidata editors. The framework is relying on question-answering technologies. We take inspiration from ideas that are used to extract facts from textual collections and adapt them to extract facts from Web pages. For achieving this, we demonstrate that language models can be adapted to extract facts not only from textual collections but also from Web pages. By exploiting the information already contained in Wikidata the proposed framework can be trained without the need for any additional learning signals and can extract new facts for a wide range of properties and domains. Following this path, Wikidata can be used as a seed to extract facts on the Web. Our experiments show that we can achieve a mean performance of 84.07 at F1-score. Moreover, our estimations show that we can potentially extract millions of facts that can be proposed for human validation. The goal is to help editors in their daily tasks and contribute to the completion of the Wikidata knowledge graph.

description: Berlesia and Katydiseius as separate genera
 The above descriptions, presenting morphological similarities as well as distinctions between Berlesia and Katydiseius, may indicate that the latter taxon is a derivative subset of the former, such that it could be considered as either a subgenus or as fully congeneric with it. A critical missing piece of the puzzle is any knowledge of the male of the monotypic Katydiseius. However, Fain & Lukoschus (1983) described the type species as having a free-living larva with chelicerae nearly as fully developed as in the protonymph, whose chelicerae in turn were not indicated to differ from the deutonymph. A fully developmental ontogenetic sequence of instars may in turn suggest other differences in behavior, including copulation. The life history of species of Berlesia is compacted/shortened, by way of nymphipary and by male copulation with females not yet eclosed from their deutonymphal skins, which may be facilitated by an extremely elongated spermatodactyl of the male. Based on the presence of a free-living and apparently functional larva, such life history compaction is not indicated in Katydiseius nadchatrami. Indeed, the parasitic association of Berlesia species with gryllacridid crickets may differ considerably from that of K. nadchatrami with pseudophylline tettigoniid crickets, such that perhaps males with extremely elongated spermatodactyls adapted for mating with pharate females should not be assumed for the latter. Note also that the deutonymph of K. nadchatrami has an entire dorsal shield like that of the female, rather than the unusual, apomorphic condition of that shield being divided in the deutonymph but entire in the adult of Berlesia species. Unlike that of Berlesia spp., the deutonymph of K. nadchatrami was not noted to have more distinctly developed claws than in other instars; this is notable as it may indicate a difference in phoresy, or even more interestingly in copulatory behavior (see ontogenetic considerations, below). The bulbiform subcapitular and coxal setae in female Berlesia are also apomorphic with respect to the simple form of those setae in Katydiseius. Each genus is diagnosed above with unique apomorphies, with the presence of other, shared apomorphies from which we infer a sister relationship.

description: Step strain experiments and dynamic light scattering measurements are perfomed to characterize the dynamic behavior of an o/w droplet microemulsion into which is incorporated a telechelic polymer. At sufficient droplet and polymer concentrations, above the percolation threshold, the system is viscoelastic and its dynamic structure factor shows up two steps for the relaxation of concentration fluctuations: the fast one is dominated by the diffusion but the slower one is almost independent of the wave vector. The terminal time of the stress relaxation tR and the slow time of the dynamic structure factor tS are both presumably controlled by the residence time of a sticker in a droplet: consistently, tR and tS are of the same order, they both vanishes at the percolation threshold according to power laws but with different exponents. We discuss these features in terms of deviations at the transition, from the usual mean field description of the dynamics of transient networks.

Radial Cutoffs and Holographic Entanglement

description: Tensor networks, $T\bar{T}$, and broader notions of a holographic principle all motivate the idea that some notion of gravitational holography should persist in the presence of a radial cutoff. But in the absence of time-reflection symmetry, the areas of Hubeny-Rangamani-Takayanagi surfaces anchored to the radial cutoff generally violate strong subadditivity, even when the associated boundary regions are spacelike separated as defined by both bulk and boundary notions of causality. We thus propose an alternate definition of cutoff-holographic entropy using a restricted maximin prescription anchored to a codimension 2 cutoff surface. For bulk solutions that respect the null energy condition, we show that the resulting areas satisfy SSA, entanglement wedge nesting, and monogamy of mutual information in parallel with cutoff free results in AdS. These results hold even when the cutoff surface fails to be convex.

description: As a step towards our understanding of galaxy evolution and for testing predictions of cosmological models we started a survey for galaxy clusters intending to identify candidates out to redshifts of ~1.5: HIROCS (= Heidelberg InfraRed/Optical Cluster Survey) is a multi-color survey (B, R, i, z and H) covering 11 square degrees in four fields on the sky. Our survey aims at a 5sigma detection of an L*+1 elliptical galaxy at z = 1.5. Classification of all objects and determination of photometric redshifts is done by the multi-color-classification scheme developed for the CADIS and COMBO-17 surveys. Cluster identification will be done by identifying overdensities in 3D-space (RA, DEC, zphot). First tests of our cluster finding algorithm on fields observed within CADIS and COMBO-17 revealed several cluster candidates.
