We propose a wider setting for this conjecture.\n  For a hypergraph $H$ let $\\nu^{(m)}(H)$ be the maximal size of a collection\nof edges, no two of which share $m$ or more vertices, and let $\\tau^{(m)}(H)$\nbe the minimal size of a collection $C$ of sets of $m$ vertices, such that\nevery edge in $H$ contains a set from $C$. We conjecture that the maximal ratio\n$\\tau^{(m)}(H)/\\nu^{(m)}(H)$ is attained in hypergraphs for which\n$\\nu^{(m)}(H)=1$. This would imply, in particular, the following generalization\nof Tuza's conjecture: if $H$ is $3$-uniform, then $\\tau^{(2)}(H)/\\nu^{(2)}(H)\n\\le 2$. (Tuza's conjecture is the case in which $H$ is the set of all triples\nof vertices of triangles in the graph). We show that most known results on\nTuza's conjecture go over to this more general setting. We also prove some\ngeneral results on the ratio $\\tau^{(m)}(H)/\\nu^{(m)}(H)$, and study the\nfractional versions and the case of $k$-partite hypergraphs.",

-      "content": "In this dissertation we provide mathematical evidence that the concept of\nlearning can be used to give a new and intuitive computational semantics of\nclassical proofs in various fragments of Predicative Arithmetic.\n  First, we extend Kreisel modified realizability to a classical fragment of\nfirst order Arithmetic, Heyting Arithmetic plus EM1 (Excluded middle axiom\nrestricted to Sigma^0_1 formulas). We introduce a new realizability semantics\nwe call \"Interactive Learning-Based Realizability\". Our realizers are\nself-correcting programs, which learn from their errors and evolve through\ntime.\n  Secondly, we extend the class of learning based realizers to a classical\nversion PCFclass of PCF and, then, compare the resulting notion of\nrealizability with Coquand game semantics and prove a full soundness and\ncompleteness result. In particular, we show there is a one-to-one\ncorrespondence between realizers and recursive winning strategies in the\n1-Backtracking version of Tarski games.\n  Third, we provide a complete and fully detailed constructive analysis of\nlearning as it arises in learning based realizability for HA+EM1, Avigad's\nupdate procedures and epsilon substitution method for Peano Arithmetic PA. We\npresent new constructive techniques to bound the length of learning processes\nand we apply them to reprove - by means of our theory - the classic result of\nGodel that provably total functions of PA can be represented in Godel's system\nT.\n  Last, we give an axiomatization of the kind of learning that is needed to\ncomputationally interpret Predicative classical second order Arithmetic. Our\nwork is an extension of Avigad's and generalizes the concept of update\nprocedure to the transfinite case. Transfinite update procedures have to learn\nvalues of transfinite sequences of non computable functions in order to extract\nwitnesses from classical proofs.",

We identify ~65,000 star-forming regions (i.e., FUV sources),\nmeasure each galaxy's luminosity function, and characterize the relationships\nbetween the luminosity function slope (alpha) and several global galaxy\nproperties. A final sample of 82 galaxies with reliable luminosity functions\nare used to define these relationships and represent the largest sample of\ngalaxies with the largest range of galaxy properties used to study the\nconnection between luminosity function properties and galaxy environment. We\nfind that alpha correlates with global star formation properties, where\ngalaxies with higher star formation rates and star formation rate densities\n(Sigma_SFR) tend to have flatter luminosity function slopes. In addition, we\nfind that neither stochastic sampling of the luminosity function in galaxies\nwith low-number statistics nor the effects of blending due to distance can\nfully account for these trends. We hypothesize that the flatter slopes in high\nSigma_SFR galaxies is due to higher gas densities and higher star formation\nefficiencies which result in proportionally greater numbers of bright\nstar-forming regions. Finally, we create a composite luminosity function\ncomposed of star-forming regions from many galaxies and find a break in the\nluminosity function at brighter luminosities. However, we find that this break\nis an artifact of varying detection limits for galaxies at different distances.",

-      "content": "In this dissertation we provide mathematical evidence that the concept of\nlearning can be used to give a new and intuitive computational semantics of\nclassical proofs in various fragments of Predicative Arithmetic.\n  First, we extend Kreisel modified realizability to a classical fragment of\nfirst order Arithmetic, Heyting Arithmetic plus EM1 (Excluded middle axiom\nrestricted to Sigma^0_1 formulas). We introduce a new realizability semantics\nwe call \"Interactive Learning-Based Realizability\". Our realizers are\nself-correcting programs, which learn from their errors and evolve through\ntime.\n  Secondly, we extend the class of learning based realizers to a classical\nversion PCFclass of PCF and, then, compare the resulting notion of\nrealizability with Coquand game semantics and prove a full soundness and\ncompleteness result. In particular, we show there is a one-to-one\ncorrespondence between realizers and recursive winning strategies in the\n1-Backtracking version of Tarski games.\n  Third, we provide a complete and fully detailed constructive analysis of\nlearning as it arises in learning based realizability for HA+EM1, Avigad's\nupdate procedures and epsilon substitution method for Peano Arithmetic PA. We\npresent new constructive techniques to bound the length of learning processes\nand we apply them to reprove - by means of our theory - the classic result of\nGodel that provably total functions of PA can be represented in Godel's system\nT.\n  Last, we give an axiomatization of the kind of learning that is needed to\ncomputationally interpret Predicative classical second order Arithmetic. Our\nwork is an extension of Avigad's and generalizes the concept of update\nprocedure to the transfinite case. Transfinite update procedures have to learn\nvalues of transfinite sequences of non computable functions in order to extract\nwitnesses from classical proofs.",

The continuum\nemission from the disk at 1.21 mm (source mm1) has a deconvolved size of\n870+/-110 AU x 330+/-300 AU and arises from a structure ~8 M_sun in mass,\ncalculated assuming a dust temperature of 190 K. The first-moment maps,\npixel-to-pixel line modeling, assuming local thermodynamic equilibrium (LTE),\nand position-velocity diagrams of the CH3CN J=13-12 K-line emission all show a\nvelocity gradient along the major axis of the source, coupled with an increase\nin velocity at small radii, consistent with Keplerian-like rotation. The LTE\nline modeling shows that where CH3CN J=13-12 is excited, the temperatures in\nthe disk range from ~70 to at least 300 K and that the H2 column density peaks\nat 2.8x10^24 cm^-2. In addition, we present Atacama Pathfinder Experiment\n(APEX) 12CO observations which show a large-scale outflow from AFGL 4176\nperpendicular to the major axis of mm1, supporting the disk interpretation.\nFinally, we present a radiative transfer model of a Keplerian disk surrounding\nan O7 star, with a disk mass and radius of 12 M_sun and 2000 AU, that\nreproduces the line and continuum data, further supporting our conclusion that\nour observations have uncovered a Keplerian disk around an O-type star.",

-      "content": "Abstract Background Current mesoscale 3D imaging techniques are limited to transparent or cleared samples or require the use of X-rays. This is a severe limitation for many research areas, as the 3D color surface morphology of opaque samples—for example, intact adult Drosophila, Xenopus embryos, and other non-transparent samples—cannot be assessed. We have developed \"ALMOST,\" a novel optical method for 3D surface imaging of reflective opaque objects utilizing an optical projection tomography device in combination with oblique illumination and optical filters. Results As well as demonstrating image formation, we provide background information and explain the reconstruction—and consequent rendering—using a standard filtered back projection algorithm and 3D software. We expanded our approach to fluorescence and multi-channel spectral imaging, validating our results with micro-computed tomography. Different biological and inorganic test samples were used to highlight the versatility of our approach. To further demonstrate the applicability of ALMOST, we explored the muscle-induced form change of the Drosophila larva, imaged adult Drosophila, dynamically visualized the closure of neural folds during neurulation of live Xenopus embryos, and showed the complementarity of our approach by comparison with transmitted light and fluorescence OPT imaging of a Xenopus tadpole. Conclusion Thus, our new modality for spectral/color, macro/mesoscopic 3D imaging can be applied to a variety of model organisms and enables the longitudinal surface dynamics during development to be revealed.",

Due to the broken circular symmetry, hexagons\nprefer to rotate upon sufficiently strong driving.

The districts such as Zeyrek, Vefa, Şehzadebaşı, Fatih, Saraçhane, Aksaray, Laleli, Cerrahpaşa, Atik Ali, Yenikapı and Nişanca were influenced by this fire. Thousands of mansions and houses, hundreds of mils and kilns, mosques, mescids, tekkes, tombs and baths destroyed by burning in the fire. In this study, the information will be given based on sources about how the fire spread, where it effected, which structures it hurt and what the size of the fire was. Furthermore, it will be addressed the socio-economic consequences of the fire in Istanbul.",

This fire started in Cibali district of the Golden Horn and spread to the Marmara coast. One third of Istanbul burned in the fire. The districts such as Zeyrek, Vefa, Şehzadebaşı, Fatih, Saraçhane, Aksaray, Laleli, Cerrahpaşa, Atik Ali, Yenikapı and Nişanca were influenced by this fire. Thousands of mansions and houses, hundreds of mils and kilns, mosques, mescids, tekkes, tombs and baths destroyed by burning in the fire. In this study, the information will be given based on sources about how the fire spread, where it effected, which structures it hurt and what the size of the fire was. Furthermore, it will be addressed the socio-economic consequences of the fire in Istanbul.",

First, we demonstrate the general principle for\nflux quantization. For particles carrying a monopole moment, the interference\ncauses monopole current to oscillate periodically with flux defined as inner\nproduct of field and area, whereas for particles carrying a fixed dipole\nmoment, the dipole current oscillates periodically with flux vector defined as\ncross product of field and trajectory. Our analysis unifies the oscillation of\nmonopole or dipole currents in various devices, such as SQUID and spin-FET,\ninto the same physical picture. Second, we show that interference effects can\nalso happen in open trajectory devices that transport dipole currents, such as\nspin Josephson effect, based on the non-gauge field nature of the interference\neffects of dipole moments. In addition, we propose that the interference effect\nof electric dipoles, known as He-McKellar-Wilkens effect, can be realized by\nthe bilayer exciton condensates observed in semiconductor heterostructure and\nbilayer graphene.",

The training of multi-speaker voice conversion systems requires a large\nnumber of resources, both in training and corpus size. Taco-VC is implemented\nusing a single speaker Tacotron synthesizer based on Phonetic PosteriorGrams\n(PPGs) and a single speaker WaveNet vocoder conditioned on mel spectrograms. To\nenhance the converted speech quality, and to overcome over-smoothing, the\noutputs of Tacotron are passed through a novel speechenhancement network, which\nis composed of a combination of the phoneme recognition and Tacotron networks.\nOur system is trained just with a single speaker corpus and adapts to new\nspeakers using only a few minutes of training data. Using mid-size public\ndatasets, our method outperforms the baseline in the VCC 2018 SPOKE\nnon-parallel voice conversion task and achieves competitive results compared to\nmulti-speaker networks trained on large private datasets.",

-      "content": "Abstract Background Current mesoscale 3D imaging techniques are limited to transparent or cleared samples or require the use of X-rays. This is a severe limitation for many research areas, as the 3D color surface morphology of opaque samples—for example, intact adult Drosophila, Xenopus embryos, and other non-transparent samples—cannot be assessed. We have developed \"ALMOST,\" a novel optical method for 3D surface imaging of reflective opaque objects utilizing an optical projection tomography device in combination with oblique illumination and optical filters. Results As well as demonstrating image formation, we provide background information and explain the reconstruction—and consequent rendering—using a standard filtered back projection algorithm and 3D software. We expanded our approach to fluorescence and multi-channel spectral imaging, validating our results with micro-computed tomography. Different biological and inorganic test samples were used to highlight the versatility of our approach. To further demonstrate the applicability of ALMOST, we explored the muscle-induced form change of the Drosophila larva, imaged adult Drosophila, dynamically visualized the closure of neural folds during neurulation of live Xenopus embryos, and showed the complementarity of our approach by comparison with transmitted light and fluorescence OPT imaging of a Xenopus tadpole. Conclusion Thus, our new modality for spectral/color, macro/mesoscopic 3D imaging can be applied to a variety of model organisms and enables the longitudinal surface dynamics during development to be revealed.",

Pairing\ncorrelations tend to make the large-amplitude nuclear collective motion more\nadiabatic by reducing the effect of those configuration changes. Competition\nbetween pairing and level crossing is thus expected to have a profound impact\non spontaneous fission lifetimes. To elucidate the role of nucleonic pairing on\nspontaneous fission, we study the dynamic fission trajectories of $^{264}$Fm\nand $^{240}$Pu using the state-of-the-art self-consistent framework. We employ\nthe superfluid nuclear density functional theory with the Skyrme energy density\nfunctional SkM$^*$ and a density-dependent pairing interaction. Along with\nshape variables, proton and neutron pairing correlations are taken as\ncollective coordinates. The collective inertia tensor is calculated within the\nnonperturbative cranking approximation.

-      "content": "Collective inertia is strongly influenced at the level crossing at which\nquantum system changes diabatically its microscopic configuration. Pairing\ncorrelations tend to make the large-amplitude nuclear collective motion more\nadiabatic by reducing the effect of those configuration changes. Competition\nbetween pairing and level crossing is thus expected to have a profound impact\non spontaneous fission lifetimes. To elucidate the role of nucleonic pairing on\nspontaneous fission, we study the dynamic fission trajectories of ^264Fm\nand ^240Pu using the state-of-the-art self-consistent framework. We employ\nthe superfluid nuclear density functional theory with the Skyrme energy density\nfunctional SkM^* and a density-dependent pairing interaction. Along with\nshape variables, proton and neutron pairing correlations are taken as\ncollective coordinates. The collective inertia tensor is calculated within the\nnonperturbative cranking approximation. The fission paths are obtained by using\nthe least action principle in a four-dimensional collective space of shape and\npairing coordinates. Pairing correlations are enhanced along the minimum-action\nfission path.

Most current prosody preserving VC systems suffer from target\nsimilarity and quality issues in the converted speech. To address these\nproblems, we first recover initial prosody preserving speech using a Phonetic\nPosteriorgrams (PPGs) based Tacotron synthesizer. Then, we enhance the quality\nof the converted speech using a novel speech-enhancement network, which is\nbased on a combination of phoneme recognition and Tacotron networks. The final\nconverted speech is generated by a Wavenet vocoder conditioned on Mel\nSpectrograms. Given the advantages of a single speaker Tacotron and Wavenet, we\nshow how to adapt them to other speakers with limited training data. We\nevaluate our solution on the VCC 2018 SPOKE task. Using public mid-size\ndatasets, our method outperforms the baseline and achieves competitive results",

According to modern concepts, Fournier's gangrene is one of the rare forms of necrotizing fasciitis of polymicrobial etiology with a primary lesion of the skin, subcutaneous tissue and superficial fascia of the scrotum, penis, and perineum. Fournier's gangrene refers to acute surgical diseases of pyonecrotic nature and is characterized by rapid septic course, high mortality, reaching 80%, in spite of the modern antibiotic therapy advances. Over the last decade the Fournier's gangrene incidence increased in 2.2-6.4 times, due to the increasing number of immunocompromised patients in the population. The disease most often occurs in older men with diabetes, alcoholism and obesity. The Fournier's gangrene occurrence is preceded by different inflammatory diseases of the colon, urinary organs, scrotum and perineum skin. The disease diagnosis in full-scale stage usually is not difficult. In rare cases, namely in the disease early stages, various radiological methods of investigation, laboratory tests and exploratory surgery with affected soft tissues express biopsy are used with differential diagnosis purposes. The cornerstone in the Fournier's gangrene treatment is an emergency surgical intervention in combination with a powerful anti-bacterial and anti-shock therapy. To improve the wound healing course and reduce the septic complications risk, new methods of adjuvant treatments such as hyperbaric oxygen therapy and vacuum therapy are used. Hospitalization duration in Fournier's gangrene is usually lengthy, due to the need to use repeated sanitation necrectomy and reconstructive plastic surgery and are associated with considerable economic costs for treatment. The Fournier's gangrene prognosis depends on the timing of specialized medical care provision and, above all, on the time interval between the disease onset and surgery performing.</jats:p>",

Key challenges include the complex and unpredictable\nnature of the real world in which assistant and service robots operate, the\nlimitations on available V&V techniques when used individually, and the\nconsequent lack of confidence in the V&V results. Our approach, called\ncorroborative V&V, addresses these challenges by combining several different\nV&V techniques; in this paper we use formal verification (model checking),\nsimulation-based testing, and user validation in experiments with a real robot.\nWe demonstrate our corroborative V&V approach through a handover task, the most\ncritical part of a complex cooperative manufacturing scenario, for which we\npropose some safety and liveness requirements to verify and validate. We\nconstruct formal models, simulations and an experimental test rig for the HRI.\nTo capture requirements we use temporal logic properties, assertion checkers\nand textual descriptions. This combination of approaches allows V&V of the HRI\ntask at different levels of modelling detail and thoroughness of exploration,\nthus overcoming the individual limitations of each technique. Should the\nresulting V&V evidence present discrepancies, an iterative process between the\ndifferent V&V techniques takes place until corroboration between the V&V\ntechniques is gained from refining and improving the assets (i.e., system and\nrequirement models) to represent the HRI task in a more truthful manner.\nTherefore, corroborative V&V affords a systematic approach to 'meta-V&V,' in\nwhich different V&V techniques can be used to corroborate and check one\nanother, increasing the level of certainty in the results of V&V.",

-      "content": "We study the averaged action of the Randall-Sundrum model with a time\ndependent metric ansatz. It can be reformulated in terms of a Brans-Dicke\naction with time dependent Newton's constant. We show that the physics of early\nuniverse, particularly inflation, is governed by the Brans-Dicke theory. The\nBrans-Dicke scalar, however, quickly settles to its equilibrium value and\ndecouples from the post-inflationary cosmology. The deceleration parameter is\nnegative to start with but changes sign before the Brans-Dicke scalar settles\nto its equilibrium value. Consequently, the brane metric smoothly exits\ninflation. We have also studied the slow-roll inflation in our model and\ninvestigated the spectra of the density perturbation generated by the radion\nfield and find them consistent with the current observations.",

First, we demonstrate the general principle for\nflux quantization. For particles carrying a monopole moment, the interference\ncauses monopole current to oscillate periodically with flux defined as inner\nproduct of field and area, whereas for particles carrying a fixed dipole\nmoment, the dipole current oscillates periodically with flux vector defined as\ncross product of field and trajectory. Our analysis unifies the oscillation of\nmonopole or dipole currents in various devices, such as SQUID and spin-FET,\ninto the same physical picture. Second, we show that interference effects can\nalso happen in open trajectory devices that transport dipole currents, such as\nspin Josephson effect, based on the non-gauge field nature of the interference\neffects of dipole moments. In addition, we propose that the interference effect\nof electric dipoles, known as He-McKellar-Wilkens effect, can be realized by\nthe bilayer exciton condensates observed in semiconductor heterostructure and\nbilayer graphene.",

These limits are now being extended both to less overweight patients and to patients over 55 years of age. Jejunoileal bypass is the treatment of choice for severely overweight patients in good general condition, allowing them to continue with their eating habits. Gastric bypass is indicated in elderly patients or in patients with previous liver diseases. It should not be performed in younger patients because of the irreversibility of the procedure. A careful postoperative long-term follow-up is necessary to prevent the complications associated with each type of operation.",

In this paper we combine an experimental design for\nmultiple independent detections of the genetic causes of a phenotype, with a\nhigh-throughput sequencing analysis that maximizes sensitivity for\ncomprehensively identifying them. Testing this approach on a set of 24 mutant\nstrains generated for a metabolic phenotype with many known genetic causes, we\nshow that this pathway-based phenotype sequencing analysis greatly improves\nsensitivity of detection compared with previous methods, and reveals a wide\nrange of pathways that can cause this phenotype. We demonstrate our approach on\na metabolic re-engineering phenotype, the PEP/OAA metabolic node in E. coli,\nwhich is crucial to a substantial number of metabolic pathways and under\nrenewed interest for biofuel research. Out of 2157 mutations in these strains,\npathway-phenoseq discriminated just five gene groups (12 genes) as\nstatistically significant causes of the phenotype. Experimentally, these five\ngene groups, and the next two high-scoring pathway-phenoseq groups, either have\na clear connection to the PEP metabolite level or offer an alternative path of\nproducing oxaloacetate (OAA), and thus clearly explain the phenotype. These\nhigh-scoring gene groups also show strong evidence of positive selection\npressure, compared with strictly neutral selection in the rest of the genome.",

-      "content": "We present an approach for the verification and validation (V&V) of robot\nassistants in the context of human-robot interactions (HRI), to demonstrate\ntheir trustworthiness through corroborative evidence of their safety and\nfunctional correctness. Key challenges include the complex and unpredictable\nnature of the real world in which assistant and service robots operate, the\nlimitations on available V&V techniques when used individually, and the\nconsequent lack of confidence in the V&V results. Our approach, called\ncorroborative V&V, addresses these challenges by combining several different\nV&V techniques; in this paper we use formal verification (model checking),\nsimulation-based testing, and user validation in experiments with a real robot.\nWe demonstrate our corroborative V&V approach through a handover task, the most\ncritical part of a complex cooperative manufacturing scenario, for which we\npropose some safety and liveness requirements to verify and validate. We\nconstruct formal models, simulations and an experimental test rig for the HRI.\nTo capture requirements we use temporal logic properties, assertion checkers\nand textual descriptions. This combination of approaches allows V&V of the HRI\ntask at different levels of modelling detail and thoroughness of exploration,\nthus overcoming the individual limitations of each technique. Should the\nresulting V&V evidence present discrepancies, an iterative process between the\ndifferent V&V techniques takes place until corroboration between the V&V\ntechniques is gained from refining and improving the assets (i.e., system and\nrequirement models) to represent the HRI task in a more truthful manner.\nTherefore, corroborative V&V affords a systematic approach to 'meta-V&V,' in\nwhich different V&V techniques can be used to corroborate and check one\nanother, increasing the level of certainty in the results of V&V.",

It can be reformulated in terms of a Brans-Dicke\naction with time dependent Newton's constant. We show that the physics of early\nuniverse, particularly inflation, is governed by the Brans-Dicke theory. The\nBrans-Dicke scalar, however, quickly settles to its equilibrium value and\ndecouples from the post-inflationary cosmology. The deceleration parameter is\nnegative to start with but changes sign before the Brans-Dicke scalar settles\nto its equilibrium value. Consequently, the brane metric smoothly exits\ninflation. We have also studied the slow-roll inflation in our model and\ninvestigated the spectra of the density perturbation generated by the radion\nfield and find them consistent with the current observations.",
