description: A technique which is known as Sumudu Transform Method (STM) is studied for the construction of solutions of a most general form of delay differential equations of pantograph type. This is a pioneer study on using the STM to construct the solutions of delay differential equations of pantograph type with variable coefficients. We obtain the exact and approximate solutions of nonlinear problems with multiproportional delays and variable coefficients. The strength of STM is illustrated in reducing the complex computational work as compared to the well-known methods. This paper shows how to succinctly identify the Lagrange multipliers for nonlinear delay differential equations with variable coefficients, using the STM. The potency and suitability of the STM are exhibited by giving expository examples. The solutions of nonlinear Volterra integro-differential equations of pantograph type are also obtained.

description: An analytic model a la Middleton of the impulsive noise component in the data of interferometric gravitational wave detectors is proposed, based on an atomic representation of glitches. A fully analytic characterization of the coherent network data analysis algorithm proposed by Rakhmanov and Klimenko is obtained, for the simplest relevant case of triggered detection of unmodeled gravitational wave bursts, using the above noise model. The detector's performance is evaluated under a suitable central-limit hypothesis, and the effects of both the noisiness of the pseudo-templates, and the presence of the impulsive noise component are highlighted.

description: Die ZBW – Leibniz-Informationszentrum Wirtschaft befasst sich schon etliche Jahre im Rahmen von angewandter Forschung mit der Entwicklung von Machine-Learning-Methoden für die Automatisierung der Inhaltserschließung. Die so entstandenen prototypischen Lösungen mussten jedoch noch in produktive Dienste überführt werden, die sich für den durchgängigen Betrieb eignen und mit den anderen Erschließungs- und Metadatenverarbeitungsprozessen der ZBW sinnvoll verzahnt werden können. Hierfür wurde die Automatisierung der Inhaltserschließung (AutoSE) 2019 zu einer Daueraufgabe erklärt und für den Aufbau einer geeigneten Software-Architektur eine Pilotphase gestartet, die bis 2024 laufen soll. Ergebnisse aus der parallel dazu fortgeführten wissenschaftlichen Methodenentwicklung fließen kontinuierlich über Experimentier- und Testphasen in das produktive System ein. Wir berichten über die bereits erreichten Meilensteine, schildern exemplarisch technische und konzeptionelle Herausforderungen, die auf dem Weg dahin überwunden werden mussten, und skizzieren die weiteren Schritte bis zum Ende der Pilotphase.

description: The paper reports a computational study of the quantum entanglement in V12 cluster molecular magnet. The low-temperature properties of the system are modelled with anisotropic quantum Heisenberg model on a tetramer of spins $S=1/2$ in the external magnetic field. The two-spin entanglement is quantified using the concurrence, whereas the fidelity serves as a measure of four-spin entanglement. The analytic and numerical results are derived and discussed, emphasizing the importance of real-space and spin-space interaction anisotropy and the role of quantum level crossings in the entanglement description in V12.

description: Many seemingly different macroscopic systems (magnets, ferroelectrics, CDW, vortices,..) can be described as generic disordered elastic systems. Understanding their static and dynamics thus poses challenging problems both from the point of view of fundamental physics and of practical applications. Despite important progress many questions remain open. In particular the temperature has drastic effects on the way these systems respond to an external force. We address here the important question of the thermal effect close to depinning, and whether these effects can be understood in the analogy with standard critical phenomena, analogy so useful to understand the zero temperature case. We show that close to the depinning force temperature leads to a rounding of the depinning transition and compute the corresponding exponent. In addition, using a novel algorithm it is possible to study precisely the behavior close to depinning, and to show that the commonly accepted analogy of the depinning with a critical phenomenon does not fully hold, since no divergent lengthscale exists in the steady state properties of the line below the depinning threshold.

description: Sparse neural networks are becoming increasingly important as the field seeks to improve the performance of existing models by scaling them up, while simultaneously trying to reduce power consumption and computational footprint. Unfortunately, most existing methods for inducing performant sparse models still entail the instantiation of dense parameters, or dense gradients in the backward-pass, during training. For very large models this requirement can be prohibitive. In this work we propose Top-KAST, a method that preserves constant sparsity throughout training (in both the forward and backward-passes). We demonstrate the efficacy of our approach by showing that it performs comparably to or better than previous works when training models on the established ImageNet benchmark, whilst fully maintaining sparsity. In addition to our ImageNet results, we also demonstrate our approach in the domain of language modeling where the current best performing architectures tend to have tens of billions of parameters and scaling up does not yet seem to have saturated performance. Sparse versions of these architectures can be run with significantly fewer resources, making them more widely accessible and applicable. Furthermore, in addition to being effective, our approach is straightforward and can easily be implemented in a wide range of existing machine learning frameworks with only a few additional lines of code. We therefore hope that our contribution will help enable the broader community to explore the potential held by massive models, without incurring massive computational cost.

description: Gridded precipitation products (GPPs) can provide precipitation data at high spatial coverage and resolution; however, no assessment has been conducted on the performance of GPPs in drought monitoring for Iran’s major basins. In this study, the accuracy of three GPPs, i.e. the Global Precipitation Climatology Centre (GPCC), Climatic Research Unit (CRU), and Climate Prediction Centre (CPC), was evaluated to derive the nonparametric Standardized Precipitation Index (SPI) for the period 1987–2016. Six common statistical metrics and typical drought event characteristic criteria, including drought area and drought class identification, were used to measure the performance of the GPPs. The results indicate that GPCC was the best dataset, with high correlation, small errors, and high detectability. The results also revealed a slight difference between the GPPs regarding the correct diagnosis of the drought classes. The findings of this study can help decision makers to effectively use GPPs in drought monitoring for Iran.

description: Shorter product life cycles and increasing individualization of production leads to an increased reconfiguration demand in the domain of industrial automation systems, which will be dominated by cyber-physical production systems in the future. In constantly changing systems, however, not all configuration alternatives of the almost infinite state space are fully understood. Thus, certain configurations can lead to process instability, a reduction in quality or machine failures. Therefore, this paper presents an approach that enhances an intelligent Digital Twin with a self-organized reconfiguration management based on adaptive process models in order to find optimized configurations more comprehensively.

description: Young stellar objects are observed to have large X-ray fluxes and are thought to produce commensurate luminosities in energetic particles (cosmic rays). This particle radiation, in turn, can synthesize short-lived radioactive nuclei through spallation. With a focus on $^{26}$Al, this paper estimates the expected abundances of radioactive nulcei produced by spallation during the epoch of planet formation. In this model, cosmic rays are accelerated near the inner truncation radii of circumstellar disks, $r_{\scriptstyle X}\approx0.1$ AU, where intense magnetic activity takes place. For planets forming in this region, radioactive abundances can be enhanced over the values inferred for the early solar system (from meteoritic measurements) by factors of $\sim10-20$. These short-lived radioactive nuclei influence the process of planet formation and the properties of planets in several ways. The minimum size required for planetesimals to become fully molten decreases with increasing levels of radioactive enrichment, and such melting leads to loss of volatile components including water. Planets produced with an enhanced radioactive inventory have significant internal luminosity which can be comparable to that provided by the host star; this additional heating affects both atmospheric mass loss and chemical composition. Finally, the habitable zone of red dwarf stars is coincident with the magnetic reconnection region, so that planets forming at those locations will experience maximum exposure to particle radiation, and subsequent depletion of volatiles.

description: One of the roadblocks for training generalist robotic models today is heterogeneity. Previous robot learning methods often collect data to train with one specific embodiment for one task, which is expensive and prone to overfitting. This work studies the problem of learning policy representations through heterogeneous pre-training on robot data across different embodiments and tasks at scale. We propose Heterogeneous Pre-trained Transformers (HPT), which pre-train a large, shareable trunk of a policy neural network to learn a task and embodiment agnostic shared representation. This general architecture aligns the specific proprioception and vision inputs from distinct embodiments to a short sequence of tokens and then processes such tokens to map to control robots for different tasks. Leveraging the recent large-scale multi-embodiment real-world robotic datasets as well as simulation, deployed robots, and human video datasets, we investigate pre-training policies across heterogeneity. We conduct experiments to investigate the scaling behaviors of training objectives, to the extent of 52 datasets. HPTs outperform several baselines and enhance the fine-tuned policy performance by over 20% on unseen tasks in multiple simulator benchmarks and real-world settings.

description: In this note, we prove triviality and nonexistence results for gradient Ricci soliton warped metrics. The proofs stem from the construction of gradient Ricci solitons that are realized as warped products, from which we know that the base spaces of these products are Ricci-Hessian type manifolds. We study this latter class of manifolds as the most appropriate setting to prove our results.

description: This work describes the rescue and enhancement of several thousand spectrophotometric plates from the La Plata Observatory. These plates and their attached handwritten documents, date from the beginning of the 20th century and contain information on observations made at different observatories around the world. Due to their fragility and the inevitable deterioration produced by the passage of time, they are being cleaned up, recovered and digitized. The information contained in the plates has a high scientific value and, based on a comparison of an old spectrum with a current one, part of the history of the star can be reconstructed. Through the ReTrOH project, we seek to translate the document into an appropriate format, preserve and disseminate that knowledge, and also recover the scientific project and the historical and personal context of the observers. The digitized spectra are available in the virtual repository (SEDICI) of the UNLP.

description: The present study aims to illustrate the efficacy of socio-hydrology in understanding the interaction between coupled human and water systems for sustainable water resource management. Future Land use land cover (LULC) growth is projected under four scenarios – business as usual (BAU), sustainable growth (SG), exponential growth (EG-1 and EG-2), and combined sustainable and economic growth (CS-EG) – for the Subarnarekha basin of India. The associated impacts of the scenarios on hydrological processes are simulated using an integrated modelling system that combines a physically based distributed hydrological model (MIKE SHE/MIKE HYDRO RIVER) and a spatially explicit integrated LULC change model (multilayer perceptron Markov model). The magnitudes of different hydrological variables suggest SG as the most favourable scenario. In contrast, the CS-EG scenario is the most plausible scenario based on the signal-to-noise ratio. The findings may provide valuable knowledge for future LULC planning in the basin. The study suggests incorporating a citizen science approach in LULC planning to reflect local preferences in the decision making process.

description: As climate changes, perennial headwater streams could become intermittent and intermittent rivers could dry more often due to more severe droughts. A modelling framework supported by field observations was applied to assess the probability of drying in headwaters at the regional scale (PD) under climate change. Empirical relationships between severity of low flows and observed proportions of no-flow states have been calibrated for 22 hydro-ecoregions under present conditions. These relationships were applied using daily discharge data on a large set of gauging stations simulated by the Modèle du Génie Rural à 6 paramètres Journalier (GR6J) hydrological model under Representative Concentration Pathway (RCP) RCP2.6 and RCP8.5 emission scenarios. The results suggest a more contrasting spatial pattern in the future than under current conditions. Noteworthy changes include increases in drying extent and duration, particularly in regions with historically high probabilities of drying and changes in seasonality in Alpine regions. Aquatic ecosystems will experience unprecedented hydrological conditions, which might lead to losses of ecosystem functions.

description: Ratgebermedien sind nahezu allgegenwärtig. In Buchform, im Zeitschriftenformat und auch im Internet bieten sie potentiellen Rezipientinnen und Rezipienten vielfältige Appelle und Strategien zur Optimierung des eigenen Verhaltens oder des Verhaltens anderer hinsichtlich Gesundheit, Pflege, Erziehung, Glück, Erfolg, Sich-Kleiden, Styling, Beauty, gesundem Kochen und zahlreichen weiteren Themen. Ratgebermedien existieren jedoch nicht nur für erwachsene Personengruppen wie Eltern oder Lehrkräfte, sondern auch für Kinder. Im Vergleich zur Elternratgeberforschung bilden das Angebot von Ratgebermedien für Kinder und ihre Inanspruchnahme durch Kinder bislang allerdings ein Forschungsdesiderat. Diesem Zustand begegnet der vorliegende Beitrag durch eine qualitative Explorationsstudie, in der die Inanspruchnahme von Ratgebermedien bei sechs- bis dreizehnjährigen Kindern hinsichtlich der medialen Formate und Themen untersucht wurde. Hierfür wurden neben vier Expertinnengesprächen 30 Interviews mit Kindern im Alter von sechs bis 13 Jahren inhaltsanalytisch ausgewertet. Die Ergebnisse zeigen, dass in der mittleren Kindheit eine hohe thematische Vielfalt an Anleitungen, Ratschlägen und Tipps mittels verschiedener Medien in Anspruch genommen wird. Von den Ergebnissen ausgehend werden Ausblicke für die künftige Erforschung von Ratgeberangeboten für Kinder herausgearbeitet.

description: Tiantian Tangs Beitrag untersucht die multiple Bedeutung des Spurbegriffs zwischen Spurenlesen bzw. Spürsinn und fasst so den medientheoretischen Stand der gegenwärtigen Dinge zusammen. Dabei wird aus bildungswissenschaftlicher Sicht betont, dass Spuren auch angesichts des digitalen Fußabdrucks gerade in einer vernetzten Wissens- und Informationsgesellschaft nicht einfach auf ein ihnen Dahinterliegendes bezogen sind, sondern vielmehr auf weitere Spuren verweisen. Gerade angesichts der Diskussionen zu Poststrukturalismus und Postmoderne kann mithin festgehalten werden, das Spuren sich vielmehr verspuren, als dass sie im polizeilichen Sinne auf Täterinnen und Täter bezogen sind. Dabei wird auch herausgearbeitet, wie angesichts von Informatik und mithin Algorithmik ein zeitgemäßer Spurbegriff modelliert und angewendet werden kann, um (mediale) Bildungsprozesse beschreiben zu können.

Aesthetic Practices of the New Right – Fake and Post-Truth as a challenge for transgressive art and cultural practices
Creators: name: Bempeza, Sofia
Publisher: name: Media Impulses
Year: 2020

description: New concepts of authoritarian (affective) populisms and right-wing extremisms challenge democratic politics within their strategic critiques of so called multiculturalism, modern cosmopolitanism and democratic liberalism; hence the politics of the New Right use aesthetic practices in an attempt to resonate within subcultures but also to reach the cultural mainstream and broader publics (see digital culture wars). The fusion of right-wing (post-truth) politics, subversive tactics and popular cultures is already in progress. Therefore the essay analyses on the one hand non-conforming and transgressive aesthetics within the context of New Right movements active in Europe (example: the Identitarians) and traces their histories (example: Casa Pound). On the other hand it discusses artistic positions that employ methods like subversive affirmation and over-identification and analyses more thoroughly the Viennese feminist group Burschenschaft Hysteria. Considering the popular and/or transgressive aesthetic practices of the New Right (and the Alt-Right) we can critically review artistic and cultural practices, which use appropriation, mimicking, fakes and over-identification as methods to distort sociopolitical phenomena. What are the current (political) possibilities of mimetic and transgressive art/cultural practices? How to avoid post-ironic confinements, nihilistic reactionary trends and the risk of becoming immune or getting neutralized? In what extend those art/cultural practices can advance their cause of complexity and ambivalence so as to go beyond simplistic relativism, post-ironic confinements and nihilistic reactionary trends?

Optimum turnout spacing on forest haul roads
Creators: name: Anderson, Dennis Ivar
Publisher: name: University of British Columbia
Year: 2010

description: Mathematical models are developed to determine the optimum spacing of turnouts and to predict the time lost due to the acceleration and deceleration of the vehicle and the time the vehicle spends in the. turnout. Previous articles have not completely defined a method of deriving or measuring the delay in the turnout attributable to turnout spacing. The concept of the expected F-factor, a measurement of the expected delay in the turnout, is introduced. The expected F-factor is the expected distance the loaded vehicle is from the empty vehicle, once the empty vehicle has come to a complete halt in the turnout, divided by the turnout spacing. . Two forms of the expected F-factor equation were developed. The results shew that the total expected delay time attributable to turnout spacing may be a significant part of the travel empty time (i.e., 20 percent) but its significance is reduced when compared to the round trip time. The optimum turnout spacing model is concerned with minimizing the sum of the turnout construction and maintenance costs and the cost of delays attributable to turnout spacing.. If the results of the optimum turnout spacing model are used in the initial design of the.road network then the total potential savings can be important. Implementation of the optimum turnout spacing model can be achieved with the .utilization of tables. These tables can be utilized as a guide in the design and construction of forest haul roads.
The Distances of SNRs Kes 69 and G21.5-0.9 from HI and 13CO Spectra

description: We obtain new HI and $^{13}$CO images around Supernova Remnants (SNR) Kes 69 and G21.5-0.9. By comparing HI spectra with $^{13}$CO emission spectra, we significantly revise the kinematic distance for Kes 69 to $\sim$ 5.5 kpc, which was 11.2 kpc, and refine the kinematic distance for G21.5-0.9 to ~4.8 kpc. For Kes 69, the highest velocity of absorption is ~86 km/s and a prominent HI emission feature at ~ 112 km/s has no respective absorption. These new results suggest that Kes 69 is associated with a newly detected extended 1720 MHz OH maser at velocity of ~85 km/s that originates from within the bright southern radio shell of Kes 69. For G21.5-0.9, the highest velocity of absorption is ~67 km/s. The HI absorption spectra of the nearby bright source PMN J1832-1035 and of Kes 69 show a common absorption feature at velocity of ~69 km/s, which is not seen for G21.5-0.9. The resulting velocity of ~68 km/s gives the best distance estimate of ~4.8 kpc for G21.5-0.9 and associated young pulsar J1833-1034.

description: Hypothesis Control of capillary flow through porous media has broad practical implications. However, achieving accurate and reliable control of such processes by tuning the pore size or by modification of interface wettability remains challenging. Here we propose that the flow of liquid by capillary penetration can be accurately adjusted by tuning the geometry of porous media and develop numerical method to achieve this. Methodologies On the basis of Darcys law, a general framework is proposed to facilitate the control of capillary flow in porous systems by tailoring the geometric shape of porous structures. A numerical simulation approach based on finite element method is also employed to validate the theoretical prediction. Findings A basic capillary component with a tunable velocity gradient is designed according to the proposed framework. By using the basic component, two functional capillary elements, namely, (i) flow amplifier and (ii) flow resistor, are demonstrated. Then, multi functional fluidic devices with controllable capillary flow are realized by integrating the designed capillary elements. All the theoretical designs are validated by numerical simulations. Finally, it is shown that the proposed model can be extended to three dimensional designs of porous media
Character change in the major plays of Jean Genet
Creators: name: Clark, Valerie Stuart
Publisher: name: University of British Columbia
Year: 2010

description: In Jean Genet's three major plays, "The Balcony", "The Blacks" and "The Screens", there is a predominating emphasis on the manipulation of dramatic identities. This study traces Genet's changing and developing use of the dramatic convention of character change as a means of character development. Two characters are drawn from each play for examination from the point of view of character change. Character in the drama is identity in action and true change in a character's dramatic identity must be accompanied by the dissolution, or death of the first identifying action and the appearance or rebirth of a new. The form of death can vary and the new identity can manifest itself in different ways, but all character changes must be accomplished through some form of dramatic death and rebirth. In "The Balcony" character change is purely a mechanical intervention by the playwright, signalled to the audience by different costumes and new names. In "The Blacks" the staging of the character changes is more literal and concrete, and carries some of the serious intent of ritual. Finally, in "The Screens" character changes grow more organically from the situations and from the evolving needs of the characters. Dramatic life in Genet includes death, and the deaths of characters in these plays is most often a transition into the state of living death. As the plays progress, death is made more and more prominent until in "The Screens" it is of equal importance with life. Revolution is a social version of death and rebirth and is structurally parallel to the process of character change. The repetitious aspect of revolution as it is used in these plays also echoes the death/rebirth metaphor of character change. It is with the main character in The Screens that Genet is finally able to successfully interlock the themes of death and revolution. Said is the most well-developed character found in Genet's work. Genet's development as a dramatist led from purely schematic character changes to the organic, subtle evolution of characterization in Said. This study shows that Said's struggle for hieratic status through character change is integrated with the plot of The Screens, making Said the perfect embodiment of Genet's world view expressed through drama. Genet was gradually able to integrate plot with character development—one of the most important accomplishments in his playwriting. But character change is the essential mode of character development in "The Balcony", "The Blacks" and "The Screens", creating wider dramatic possibilities, carrying events forward, giving shape to the action and determining the shape of the plays.

description: Nutrition standards for the USDA’s National School Lunch program were updated in 2012, with changes requiring more fruit and vegetables. Most of the foods served in school meals come from commercial sources, but USDA also offers foods to schools in a program called USDA Foods. This report examines changes in food choices in the USDA Foods program during 2006–17 in response to revised nutrition standards. The report finds that the value of fresh fruits and vegetables ordered from USDA Foods and distributed by the U.S. Department of Defense DoD Fresh program rose from 5 to 15 percent of the value of all USDA Foods orders.
