description: This paper presents a new video question answering task on screencast tutorials. We introduce a dataset including question, answer and context triples from the tutorial videos for a software. Unlike other video question answering works, all the answers in our dataset are grounded to the domain knowledge base. An one-shot recognition algorithm is designed to extract the visual cues, which helps enhance the performance of video question answering. We also propose several baseline neural network architectures based on various aspects of video contexts from the dataset. The experimental results demonstrate that our proposed models significantly improve the question answering performances by incorporating multi-modal contexts and domain knowledge.

description: We apply the Smaller ALignment Index (SALI) method to a 4--dimensional mapping of accelerator dynamics in order to distinguish rapidly, reliably and accurately between ordered and chaotic motion. The main advantage of this index is that it tends {\it exponentially} to zero in the case of chaotic orbits, while it fluctuates around non--zero values in the case of quasiperiodic trajectories. Thus, it avoids the notorious ambiguities concerning the eventual convergence of (maximum) Lyapunov exponents to (positive) non-zero values. Exploiting the different behavior of SALI in these two cases we produce phase space `charts' where regions of chaos and order are clearly identified. Evaluating the percentage of chaotic and escaping orbits as a function of the distance from the origin we are able to estimate rapidly and accurately the boundaries of the {\it dynamical aperture} of a proton beam, passing repeatedly through an array of magnetic focusing elements.

description: A theoretical model based on the molecular interactions between a growing tumor and a dynamically evolving blood vessel network describes the transformation of the regular vasculature in normal tissues into a highly inhomogeneous tumor specific capillary network. The emerging morphology, characterized by the compartmentalization of the tumor into several regions differing in vessel density, diameter and necrosis, is in accordance with experimental data for human melanoma. Vessel collapse due to a combination of severely reduced blood flow and solid stress exerted by the tumor, leads to a correlated percolation process that is driven towards criticality by the mechanism of hydrodynamic vessel stabilization.

Problems with Lorentz Violation Originating From a Cosmologically Varying Pseudoscalar Field

description: Lorentz- and CPT-violating models of electrodynamics with Chern-Simons terms are typically plagued by various sorts of instabilities. However, when the Chern-Simons term arises from a slow time variation in a pseudoscalar field with an axion-like electromagnetic coupling, the total energy of the theory is bounded below. We examine the behavior of such a theory, finding that in a systematic power series expansion of the magnetic and pseudoscalar fields, singularities appear in the field profiles. Some of the questionable behavior can be cured by taking a fully nonperturbative approach, but other problematic terms remain. This may be an indication that Cerenkov-like radiation will automatically carry away energy from a moving charge, preventing a charge from moving with uniform velocity over extended distances.

description: We report additional experimental evidences about the presence of an universal behavior in the Field-Temperature Phase Diagram of Type II Superconductors. This behavior is characterized by a phase transition in the vortex matter between the disordered and the Bragg Glass phase. The experimental detection of a Peak Effect phenomenon has been proved to be strictly connected to the existence of this phase transition. In this paper, we show the first observation of a Peak Effect in the compound Nb3Sn, by using 1st harmonics of the AC magnetic susceptibility. Peak Effect has been detected at fields between 3T and 13T, whereas it is not observable at higher fields. This seems to be in contrast with the theoretical predictions of such a phase transition at all fields. Nevertheless, by measuring the 3rd harmonics of the AC susceptibility, this phase transition has been detected up to our highest available field (19 T), thus demonstrating the necessity of the higher harmonics analysis in studying these topics and moreover proving the validity of the theoretical predictions.

description: Capturing the shape and spatially-varying appearance (SVBRDF) of an object from images is a challenging task that has applications in both computer vision and graphics. Traditional optimization-based approaches often need a large number of images taken from multiple views in a controlled environment. Newer deep learning-based approaches require only a few input images, but the reconstruction quality is not on par with optimization techniques. We propose a novel deep learning architecture with a stage-wise estimation of shape and SVBRDF. The previous predictions guide each estimation, and a joint refinement network later refines both SVBRDF and shape. We follow a practical mobile image capture setting and use unaligned two-shot flash and no-flash images as input. Both our two-shot image capture and network inference can run on mobile hardware. We also create a large-scale synthetic training dataset with domain-randomized geometry and realistic materials. Extensive experiments on both synthetic and real-world datasets show that our network trained on a synthetic dataset can generalize well to real-world images. Comparisons with recent approaches demonstrate the superior performance of the proposed approach.

description: The Wide-Field Infrared Survey Telescope (WFIRST) will answer fundamental questions about the evolution of dark energy over time and expand the catalog of known exoplanets into new regions of parameter space. Using a Hubble-sized mirror and 18 newly developed HgCdTe 4K x 4K photodiode arrays (H4RG-10), WFIRST will measure the positions and shapes of hundreds of millions of galaxies, the light curves of thousands of supernovae, and the microlensing signals of over a thousand exoplanets toward the bulge of the Galaxy. These measurements require unprecedented sensitivity and characterization of the Wide Field Instrument (WFI), particularly its detectors. The WFIRST project undertook an extensive detector development program to create focal plane arrays that meet these science requirements. These prototype detectors have been characterized and their performance demonstrated in a relevant space-like environment (thermal vacuum, vibration, acoustic, and radiation testing), advancing the H4RG-10's technology readiness level (TRL) to TRL-6. We present the performance characteristics of these TRL-6 demonstration devices.

description: We present the evolutionary models of metal-free stars in the mass range from 0.8 to 1.2 Msun with up-to-date input physics. The evolution is followed to the onset of hydrogen mixing into a convection, driven by the helium flash at red giant or asymptotic giant branch phase. The models of mass M >= 0.9 Msun undergo the central hydrogen flash, triggered by the carbon production due to the 3-alpha reactions. We find that the border of the off-center and central ignition of helium core flash falls between 1.1 and 1.2 Msun; the models of mass M <= 1.1 Msun experience the hydrogen mixing at the tip of red giant branch while the models of M = 1.2 Msun during the helium shell flashes on the asymptotic giant branch. The equation of state for the Coulomb liquid region, where electron conduction and radiation compete, is shown to be important since it affects the thermal state in the helium core and influences the red giant branch evolution. It is also found that the non-resonant term of 3-alpha reactios plays an important role, although it has negligible effect in the evolution of stars of younger populations. We compare our models with the computations by several other sets of authors, to confirm the good agreement except for one study which finds the helium ignition much closer to the center with consequences important for subsequent evolution.

description: From general arguments, that are valid for spin models with sufficiently short-range interactions, we derive strong constraints on the excitation spectrum across a continuous phase transition at zero temperature between a magnetic and a dimerized phase, that breaks the translational symmetry. From the different symmetries of the two phases, it is possible to predict, at the quantum critical point, a branch of gapless excitations, not described by standard semi-classical approaches. By using these arguments, supported by intensive numerical calculations, we obtain a rather convincing evidence in favor of a first-order transition from the ferromagnetic to the dimerized phase in the two-dimensional spin-half model with four-spin ring-exchange interaction, recently introduced by A.W. Sandvik et al. [Phys. Rev. Lett. 89, 247201 (2002)].

In this note, we present a fractional version of Haemers' bound on the Shannon capacity of a graph, which is originally due to Blasiak. This bound is a common strengthening of both Haemers' bound and the fractional chromatic numberof a graph. We show that this fractional version outperforms any bound on the Shannon capacity that could be attained through Haemers' bound. We show also that this bound is multiplicative, unlike Haemers' bound.With Boris Bukh.In IEEE Transactions on Information Theory, vol. 65, no. 6, pp. 3340{3348, Jun. 2019.
Inverting the Turan problem. Classical questions in extremal graph theory concern the asymptotics of ex(G;H) where H is a ?fixed family of graphs and G = Gn is taken from a "standard" increasing sequence of host graphs (G1;G2; : : : ) most often Kn or Kn;n. Inverting the question, we can instead ask how large e(G) can be with respect to ex(G;H). We show that the standard sequences indeed maximize e(G) for some choices of H, but not for others. Many interesting questions and previous results arise very naturally in this context, which also, perhaps unusually, gives rise to sensible extremal questions concerning multigraphs and non-uniform hypergraphs.With Joe Briggs.In Discrete Mathematics, vol. 342, no. 7, pp. 1865{1884, Jul. 2019.

description: In recent years, algorithm research in the area of recommender systems has shifted from matrix factorization techniques and their latent factor models to neural approaches. However, given the proven power of latent factor models, some newer neural approaches incorporate them within more complex network architectures. One specific idea, recently put forward by several researchers, is to consider potential correlations between the latent factors, i.e., embeddings, by applying convolutions over the user-item interaction map. However, contrary to what is claimed in these articles, such interaction maps do not share the properties of images where Convolutional Neural Networks (CNNs) are particularly useful. In this work, we show through analytical considerations and empirical evaluations that the claimed gains reported in the literature cannot be attributed to the ability of CNNs to model embedding correlations, as argued in the original papers. Moreover, additional performance evaluations show that all of the examined recent CNN-based models are outperformed by existing non-neural machine learning techniques or traditional nearest-neighbor approaches. On a more general level, our work points to major methodological issues in recommender systems research.

description: A computer model can be used for predicting an output only after specifying the values of some unknown physical constants known as calibration parameters. The unknown calibration parameters can be estimated from real data by conducting physical experiments. This paper presents an approach to optimally design such a physical experiment. The problem of optimally designing physical experiment, using a computer model, is similar to the problem of finding optimal design for fitting nonlinear models. However, the problem is more challenging than the existing work on nonlinear optimal design because of the possibility of model discrepancy, that is, the computer model may not be an accurate representation of the true underlying model. Therefore, we propose an optimal design approach that is robust to potential model discrepancies. We show that our designs are better than the commonly used physical experimental designs that do not make use of the information contained in the computer model and other nonlinear optimal designs that ignore potential model discrepancies. We illustrate our approach using a toy example and a real example from industry.

description: We investigate the fermionic one-loop cross section for the two photon annihilation of Kaluza-Klein (KK) dark matter particles in a model of universal extra dimensions (UED). This process gives a nearly mono-energetic gamma-ray line with energy equal to the KK dark matter particle mass. We find that the cross section is large enough that if a continuum signature is detected, the energy distribution of gamma-rays should end at the particle mass with a peak that is visible for an energy resolution of the detector at the percent level. This would give an unmistakable signature of a dark matter origin of the gamma-rays, and a unique determination of the dark matter particle mass, which in the case studied should be around 800 GeV. Unlike the situation for supersymmetric models where the two-gamma peak may or may not be visible depending on parameters, this feature seems to be quite robust in UED models, and should be similar in other models where annihilation into fermions is not helicity suppressed. The observability of the signal still depends on largely unknown astrophysical parameters related to the structure of the dark matter halo. If the dark matter near the galactic center is adiabatically contracted by the central star cluster, or if the dark matter halo has substructure surviving tidal effects, prospects for detection look promising.

description: Spectroscopy of doubly magic $^{132}_{50}$Sn$_{82}$ has been performed with the GRIFFIN spectrometer at TRIUMF-ISAC following the $β$ decay of $^{132}_{49}$In$_{83}$. The analysis has allowed for the placement of a total of 70 transitions and 29 excited states in $^{132}$Sn. Detailed spectroscopy has also been performed on $^{131}$Sb, resulting from the $β$ decay of $^{131}$Sn, produced from the $β$-delayed neutron decay of $^{132}$In. Measurement of $γ$-rays in both $^{131}$Sn and $^{131}$Sb has led to the determination of the $β$-delayed neutron emission probability, $P_{n}$, from $^{132}$In. This is the first time the $P_{n}$ has been measured for this nucleus using $γ$ spectroscopy, and the new value of 12.3(4)% is consistent with the most recent $β-n$ counting experiment. Additionally, $γ$-$γ$ angular correlations have been performed in $^{132}$Sn, supporting the spin assignments of several excited states. Novel ab initio calculations are presented which describe several of the excited states, and these are compared to the experimental spectrum.

description: This paper analyzes the strategic alliance between Swine Raisers Cooperative from Encantado - RS (Cosuel) and Tetra Park the processing unit of sterilized box milk (Long Life Milk). As academic interesting topics, the following issues were studied: the environment before, during and after the alliance, taking as theoretical base the work of Yoshino and Rangan (1996); the perception of the managers and associates regarding the changes which occurred in the cooperative taking as theoretical base the works of Mintzberg, Ahlstrand & Lampel (2000); and, additionally, a double complexity model was applied, taking as theoretical base the works of Pedrozo (1995). Also was explored the cultural change which took place in the cooperative as a whole (rural property, industry and the final consumer), and made it possible for Cosuel to develop competitive actions with limited financial aid and actions.

description: Managers craft strategies that, if successfully implemented, can improve profitability and financial performance over time. Can firms repeat their performance over time? If so, then a manager who crafted a successful strategy could expect her/his firm to achieve greater profitability relative to other firms within its industry. The objective of this study was to compare business performance (accounting profitability) for publicly traded and cooperatively-owned food and agribusiness firms. We used the Standard and Poors Compustat database using the methodology of McGahan and Porter's paper which used on 4,112 manufacturing firms. Return on investment for each SIC code in each year was calculated. A regression equation with return on investment as the dependent variable and the average returns on the right hand side were used in a weighted least squares regression. The data was broken out into processing, wholesaling, restaurants, and retail supermarkets. Industry effects are greatest across all business segments and the processing sector. The retail supermarket sector has had relatively stable profits due to both industry and firm effects over time. This would suggest that the retail industry structure is conducive to stable profits and that firms within the industry are able to differentiate themselves, which also contributes to permanence of profits. Our results suggest that industry structure does not contribute to stable profits in the wholesale and restaurant sector. Industry effects are more persistent than corporate effects. These implications are also of interest to land grant universities. Agribusiness economics research and extension programs exist at many land grant universities to educate producers and management about producer-owned businesses. Finally, persistence of profitability in certain firms has long been noted by economists. Further research is needed on identifying characteristics of those firms that contribute to their persistent profits.

description: The present paper focuses on the perceived quality of information exchange between government and business (G2B) in the field of environmental reporting in the Dutch agrifood industry. It seems most important for environmental performance enhancement (a concept that includes the quality of information given to stakeholders in our view) that companies are entangled in a network of intermediary institutions (branch organizations, covenants, existence of chain leaders etc.). It seems that that these mediating institutions are very instrumental in translating the governmental message to the companies. The companies choose the (related to the development of internal care) improvement of electronic reporting as the most promising innovation for the G2B communication. This shows that the companies still have a long way to go towards chain oriented care systems.

description: The new generation of telecommunication systems must provide acceptable data rates and spectral efficiency for new applications. Recently massive MIMO has been introduced as a key technique for the new generation of telecommunication systems. Cell-free massive MIMO system is not segmented into cells. Each BS antennas are distributed throughout the environment and each user is served by all BSs, simultaneously. In this paper, the performance of the multiuser cell-free massive MIMO-system exploying space-time block codes in the uplink, and with linear decoders is studied. An Inverse matrix approximation using Neumann series is proposed to reduce the computational and hardware complexity of the decoding in the receiver. For this purpose, each user has two antennas, and also for improving the diversity gain performance, space-time block codes are used in the uplink. Then, Neumann series is used to approximate the inverse matrix in ZF and MMSE decoders, and its performance is evaluated in terms of BER and spectral efficiency. In addition, we derive lower bound for throughput of ZF decoder. The simulation results show that performance of the system , in terms of BER and spectral efficiency, is better than the single-antenna users at the same system. Also, the BER performance in a given system with the proposed method will be close to the exact method.

description: While a growing body of literature finds positive impacts of Start-Up Subsidies (SUS) on labor market outcomes of participants, little is known about how the design of these programs shapes their effectiveness and hence how to improve policy. As experimental variation in program design is unavailable, we exploit the 2011 reform of the current German SUS program for the unemployed which strengthened case-workers’ discretionary power, increased entry requirements and reduced monetary support. We estimate the impact of the reform on the program’s effectiveness using samples of participants and non-participants from before and after the reform. To control for time-constant unobserved heterogeneity as well as differential selection patterns based on observable characteristics over time, we combine Difference-in-Differences with inverse probability weighting using covariate balancing propensity scores. Holding participants’ observed characteristics as well as macroeconomic conditions constant, the results suggest that the reform was successful in raising employment effects on average. As these findings may be contaminated by changes in selection patterns based on unobserved characteristics, we assess our results using simulation-based sensitivity analyses and find that our estimates are highly robust to changes in unobserved characteristics. Hence, the reform most likely had a positive impact on the effectiveness of the program, suggesting that increasing entry requirements and reducing support in-creased the program’s impacts while reducing the cost per participant.

description: The competitiveness of the agribusiness sector is critical to the social and economic sustainability of regional Australia, where agribusiness is directly responsible for one in five jobs (DNRE, 2002). Although it is recognised that environmental issues must be considered in order to 'sustain' the natural resources used to produce food, this paper focuses on the social and economic issues relating to sustainability (Cocklin et at., 2001). Social sustainability has only recently been upheld as an aim of agricultural and regional policy in Australia, however, it has typically been considered less important than economic and ecological sustainability (Cocklin et al., 2001). In rural Australia, social sustainability is typically reflected in the maintenance of social networks among residents of a rural area, the viability of the rural towns and the associated provision of infrastructure, facilities and services. The State Government of Victoria is actively encouraging the development and maintenance of sustainable networks of agribusiness-related entities in regional and rural Victoria. The Victoria Agribusiness Networks program is an example of how government is engaging agribusiness communities in regional Victoria.

description: We consider a holographic dark energy model, in which both the CC energy density rho_Lambda and the Newton constant G_N are varying quantities, to study the problem of setting an effective field-theory IR cutoff. Assuming that ordinary matter scales canonically, we show that the continuity equation univocally fixes the IR cutoff, provided a law of variation for either rho_Lambda or G_N is known. Previous considerations on holographic dark energy disfavor the Hubble parameter as a candidate for the IR cutoff (for spatially flat universes), since in this case the ratio of dark energy to dark matter is not allowed to vary, thus hindering a deceleration era of the universe for the redshifts z>=0.5. On the other hand, the future event horizon as a choice for the IR cutoff is being favored in the literature, although the `coincidence problem' usually cannot be addressed in that case. We extend considerations to spatially curved universes, and show that with the Hubble parameter as a choice for the IR cutoff one always obtains a universe that never accelerates or a universe that accelerates all the time, thus making the transition from deceleration to acceleration impossible. Next, we apply the IR cutoff consistency procedure to a RG running CC model, in which the low-energy variation of the CC is due to quantum effects of particle fields having masses near the Planck scale. We show that bringing such a model in full accordance with holography amounts to having such an IR cutoff which scales as a square root of the Hubble parameter. We find that such a setup, in which the only undetermined input represents the true ground state of the vacuum, can give early deceleration as well as late time acceleration. The possibility of further improvement of the model is also briefly indicated.

description: Purpose: Macrostructural narrative analyses are important clinical measures, revealing age-related declines and disorder-related impairments in the accuracy, completeness, logical sequencing, and organization of content. The current study aims to provide preliminary data on typical aging and psychometric evidence supporting multilevel Main Concept, Sequencing, and Story Grammar (MSSG) analyses that capture these aspects of narratives.Method: Transcripts of Cinderella narratives for 92 healthy control participants stratified across four age brackets from the online database AphasiaBank were coded by Richardson and Dalton (2016) for main concept (MC) analysis. In the current study, MSSG analyses were completed for (a) logical sequencing, independently and in combination with MC accuracy and completeness (MC + sequencing), and (b) story grammar organization (i.e., inclusion of episodic components and complexity of episodes). Interrater agreement (99%–100%) revealed highly reliable scoring.Results: Descriptive statistics for the typically aging sample are presented for sequencing, MC + sequencing, total episodic components, and episodic complexity. Scores for participants over 60 years of age were lower (poorer) than scores for those 20–59 years of age, supporting the construct validity of score use for identifying age-related declines in performance.Conclusions: This study’s novel MSSG analyses of narrative production efficiently assess the logical sequencing and story grammar organization of content in healthy controls. Preliminary reliability and validity evidence support the use of all scores to measure age-related changes in narrative macrostructure. Data from this typically aging sample provide a foundation for future research and clinical assessment aimed at quantifying narrative deficits in adults with communication disorders.

description: Large genetic diversity exists in Lupinus albus L. expressed by its morphological and agronomical traits. The aim of this study was to assess the genetic diversity of ten white lupin accessions regarding components of productivity and biological traits. Two years trial was carried out on the experimental field of Institute of plant genetic resources during the period 2018-2019. The traits were evaluated using the International Lupinus albus descriptor; the degree of earliness - by Kuzmova, 2002. Based on agro-morphological traits the studied accessions were grouped into two clusters. The first cluster included only one accession. The second claster was divided into two sub-clusters. The first sub-cluster included three genotypes which differed significantly from the remaining ones by its tall plants, high first formed pods and a big number of grains per plant. The second sub-cluster included six accessions possessing medium-high to short stem and medium-large to large grains. The studied traits were combined into two main clusters. The largest Euclidean distance had between vegitation period and other studied traits. According to the degree of earliness, the lupen genotypes were clustered into three groups - ultra-early, early and late. The BGR 3086 accession was selected also as an ultra-early variety with 1.00 coefficient of earliness together with two other genotypes - selected to the early group with a coefficient of earliness 1.60. Genetically distant genotypes will be involved in the breeding programs for effective combining the important features into a new genotype.

description: The Protocol resulting from the 1997 Conference of Parties in Kyoto finally set emission caps for several developed countries and introduced the possibility of market creation mechanisms on carbon emission trading. The Clean Development Mechanism (CDM) was then created for emission trading between countries with caps and those with no caps. The CDM market will pursue the opportunities for lowest costs on carbon reductions available in each country with no emission target, as is the case of Brazil. The positive differentials of Brazil will only be realized if there is, mainly in national terms, a favorable atmosphere to the development of new business and the proper importance to the environmental commitments of reduction of the greenhouse effect. The excess of bureaucracy and governmental controls added to the lack of a policy and of a clear institutional guidance of support to the consistent initiatives of CDM projects. They are decisive obstacles for the achievement of the potentialities and for a good position of Brazil in the trade of CERs. Making use of the teachings of Nobel Prize Ronald Coase, this paper has as a goal to show the necessary institutional conditions for Brail to make use of the development from this market.

description: The paper studies valuation ratios of food companies that were part of mergers & acquisitions (M&A) involving at least one French company during the 1996-2001 period. Results converge to value the food company 1.1 to 1.4 times its turnover. There is no significant difference of "valuation to turnover" ratios among M&A involving only French firms and M&A involving companies from different countries. Corporate valuation may differ according to food sub-sector.
