description: Ultrafast lasers are an increasingly important tool to control and stabilize emergent phases in quantum materials. Among a variety of possible excitation protocols, a particularly intriguing route is the direct light-engineering of microscopic electronic parameters, such as the electron hopping and the local Coulomb repulsion (Hubbard $U$). In this work, we use time-resolved x-ray absorption spectroscopy to demonstrate the light-induced renormalization of the Hubbard $U$ in a cuprate superconductor, La$_{1.905}$Ba$_{0.095}$CuO$_4$. We show that intense femtosecond laser pulses induce a substantial redshift of the upper Hubbard band, while leaving the Zhang-Rice singlet energy unaffected. By comparing the experimental data to time-dependent spectra of single- and three-band Hubbard models, we assign this effect to a $\sim140$ meV reduction of the onsite Coulomb repulsion on the copper sites. Our demonstration of a dynamical Hubbard $U$ renormalization in a copper oxide paves the way to a novel strategy for the manipulation of superconductivity, magnetism, as well as to the realization of other long-range-ordered phases in light-driven quantum materials.

description: The recently proposed optical elements containing semitransparent wavelike films embedded into the transparent material are investigated. Such optical elements do not distort a wave transmitted through them. Novel optical elements can be fabricated using well-known embossing methods. Their possible applications are discussed. The optical elements containing holographic wavelike films can be used for color holography, for augmented reality wearable glasses, as a beam combiner for head-up displays. The optical elements containing diffuse wavelike films can be used as an alternative for tinted car windows, instead of mirror-glass windows in high-rise buildings, for shop-windows, for one-way privacy windows, for printing images on eyeglasses. The scheme of a waveguide display with a single-layer holographic wavelike films is analyzed. The feasibility of the proposed applications is verified by estimation of the optical elements parameters and computer simulation, and measurements conducted on an experimental specimen.

description: We describe the QUaD experiment, a millimeter-wavelength polarimeter designed to observe the Cosmic Microwave Background (CMB) from a site at the South Pole. The experiment comprises a 2.64 m Cassegrain telescope equipped with a cryogenically cooled receiver containing an array of 62 polarization-sensitive bolometers. The focal plane contains pixels at two different frequency bands, 100 GHz and 150 GHz, with angular resolutions of 5 arcmin and 3.5 arcmin, respectively. The high angular resolution allows observation of CMB temperature and polarization anisotropies over a wide range of scales. The instrument commenced operation in early 2005 and collected science data during three successive Austral winter seasons of observation.

This paper proposes a practical power flow solution framework employing a set of droop equations that govern voltage and phase angle of DERs and, along with the system frequency, to directly solve the power flow of a multi-phase multi-wire unbalanced islanded microgrid.
Recent advances in inverter-based distributed energy resources (DERs) allow microgrids to operate in grid-connected and islanded modes with ease. However, determining a steady-state load flow solution of a real-world unbalanced and islanded three-phase microgrid remains a challenge. Existing methods are either unsuitable, labor-intensive or computationally demanding for a long-term analysis of islanded microgrids. To address these issues, we propose a practical solution framework that employs externally-updated system frequency, power quantities, and droop characteristics governing the voltage and phase angle of DERs in every iteration as inputs to an off-the-shelf open-source multi-phase, multi-wire, unbalanced power flow software tool to solve an islanded-microgrid power flow. Using our framework, users only need to implement a set of droop equations and update system variables. The power flow solution is accomplished entirely by an off-the-shelf power flow tool, e.g., OpenDSS. Our proposed framework can model a microgrid of any arbitrary configuration and operating condition. We demonstrate and validate the proposed method's efficacy by comparing its results with those modeled using a time-domain simulation with PSCAD/EMTDC. Finally, an example of a quasi-static time-series study is presented to better illustrate the application of such a tool.

This paper describes the recently developed network of six magnetometers in the US state of Texas.
Monitoring the elements associated with geomagnetic disturbances (GMDs), such as the earth's magnetic field, can help mitigate their negative impacts on the power grid. While there are existing magnetometers monitoring this in certain locations, they are currently sparse and have several gaps in coverage such as the southern US region. This paper describes the recently developed network of six magnetometers in the US state of Texas. Aspects such as the site selection, physical description of a magnetometer station, and data communication are described. Data quality is tested using correlation analysis among these magnetometers and pre-existing magnetic observatories. A real-time magnetic field data streaming and visualization setup is developed, with provisions to make the data available to researchers and industry.

In this paper, a novel safe reinforcement learning-based resilient proactive scheduling strategy is proposed for commercial buildings subject to extreme weather events.
It is a crucial yet challenging task to ensure commercial load resilience during high-impact, low-frequency extreme events. In this paper, a novel safe reinforcement learning (SRL)-based resilient proactive scheduling strategy is proposed for commercial buildings (CBs) subject to extreme weather events. It deploys the correlation between different CB components with demand response capabilities to maximize the customer comfort levels while minimizing the energy reserve cost. It also develops an SRL-based algorithm by combining deep-Q-network and conditional-value-at-risk methods to handle the uncertainties in the extreme weather events such that the impact from extreme epochs in the learning process is greatly mitigated. As a result, an optimum control decision can be derived that targets proactive scheduling goals, where exploration and exploitation are considered simultaneously. Extensive simulation results show that the proposed SRL-based proactive scheduling decisions can ensure the resilience of a commercial building while maintaining comprehensive comfort levels for the occupants.

This paper presents a novel dynamic programming technique for the determination of optimal investment decisions to improve power distribution system reliability metrics.
This paper presents a novel dynamic programming (DP) technique for the determination of optimal investment decisions to improve power distribution system reliability metrics. This model is designed to select the optimal small-scale investments to protect an electrical distribution system from disruptions. The objective is to minimize distribution system reliability metrics: System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI). The primary input to this optimization model is years of recent utility historical outage data. The DP optimization technique is compared and validated against an equivalent mixed integer linear program (MILP). Through testing on synthetic and real datasets, both approaches are verified to yield equally optimal solutions. Efficiency profiles of each approach indicate that the DP algorithm is more efficient when considering wide budget ranges or a larger outage history, while the MILP model more efficiently handles larger distribution systems. The model is tested with utility data from a distribution system operator in the U.S. Results demonstrate a significant improvement in SAIDI and SAIFI metrics with the optimal small-scale investments.

description: A comparison of the 2MASS flux dipole to the CMB dipole can serve as a method to constrain a combination of the cosmological parameter Omega_m and the luminosity bias of the 2MASS survey. For this constraint to be as tight as possible, it is necessary to maximize the correlation between the two dipoles. This can be achieved by optimizing the survey window through which the flux dipole is measured. Here we explicitly construct such a window for the 2MASS survey. The optimization in essence reduces to excluding from the calculation of the flux dipole galaxies brighter than some limiting magnitude K_min of the near-infrared K_s band. This exclusion mitigates nonlinear effects and shot noise from small scales, which decorrelate the 2MASS dipole from the CMB dipole. Under the assumption of negligible shot noise we find that the optimal value of K_min is about five. Inclusion of shot noise shifts the optimal K_min to larger values. We present an analytical formula for shot noise for the 2MASS flux dipole, to be used in follow-up work with 2MASS data. The misalignment angle between the two dipoles is a sensitive measure of their correlation: the higher the correlation, the smaller the expectation value of the angle. A minimum of the misalignment is thus a sign of the optimal gravity window. We model analytically the distribution function for the misalignment angle and show that the misalignment estimated by Maller et al. is consistent with the assumed underlying model (though it is greater than the expectation value). We predict with about 90% confidence that the misalignment will decrease if 2MASS galaxies brighter than K_min = 5 mag are excluded from the calculation of the flux dipole. This prediction has been indirectly confirmed by the results of Erdogdu et al. (ABRIDGED)

description: In dieser Arbeit werden das Tragverhalten und die Tragfähigkeit von stabilitätsgefährdeten Bauteilen mit doppeltsymmetrischen I-Querschnitten untersucht. Es werden mehrere Bemessungskonzepte für den Stabilitätsnachweis Biegedrillknicken unter Berücksichtigung von geometrischen Ersatzimperfektionen und Schnittgrößen nach Theorie II. Ordnung entwickelt. Anhand von numerischen Simulationen zahlreicher physikalischer Traglastversuche mit Hilfe der geometrisch und materiell nichtlinearen Berechnung unter Berücksichtigung von geometrischen Imperfektionen und Eigenspannungen werden das nichtlineare Tragverhalten und darauf einflussnehmende Faktoren eingehend analysiert. Besonderer Fokus wird auf den Traglasteinfluss von Imperfektionen gelegt, die jedes reale Bauteil aufweist und in einem idealisierten FE-Modell durch repräsentative Imperfektionsannahmen abgebildet werden. Auf Grundlage von numerisch erzielten Traglasten werden erforderliche geometrische Ersatzimperfektionen abgeleitet. Durch umfangreiche Parameterstudien werden die wesentlichen Zusammenhänge zwischen den erforderlichen Ersatzimperfektionsgrößen und verschiedenen Parametern, wie z.B. die Querschnittsgeometrie, die Bauteilschlankheit, die Beanspruchungsart, Stahlsorte, die Imperfektionsform und die beim Querschnittsnachweis angewendete Interaktionsbeziehung identifiziert. Basierend darauf wurden Bemessungskonzepte für zwei unterschiedliche Imperfektionsformen entwickelt, die mit den Regelungen des Eurocode 3-1-1 konform sind.

Суть такого метода заключается во включении процентных выплат в расходы организации для снижения налоговой базы по налогу на прибыль. В данной статье были рассмотрены основные методы борьбы налоговых органов РФ с подобным способом снижения налоговой нагрузки при помощи правила тонкой капитализации, а также приведена судебная практика. В конце статьи сделан вывод, что при решении дел, имеющих признаки тонкой капитализации, важно обращать внимание на конкретные детали каждого спора, а не руководствоваться исключительно формальным подходом.

description: As a distributed learning approach, federated learning trains a shared learning model over distributed datasets while preserving the training data privacy. We extend the application of federated learning to parking management and introduce FedParking in which Parking Lot Operators (PLOs) collaborate to train a long short-term memory model for parking space estimation without exchanging the raw data. Furthermore, we investigate the management of Parked Vehicle assisted Edge Computing (PVEC) by FedParking. In PVEC, different PLOs recruit PVs as edge computing nodes for offloading services through an incentive mechanism, which is designed according to the computation demand and parking capacity constraints derived from FedParking. We formulate the interactions among the PLOs and vehicles as a multi-lead multi-follower Stackelberg game. Considering the dynamic arrivals of the vehicles and time-varying parking capacity constraints, we present a multi-agent deep reinforcement learning approach to gradually reach the Stackelberg equilibrium in a distributed yet privacy-preserving manner. Finally, numerical results are provided to demonstrate the effectiveness and efficiency of our scheme.

description: Abstract

This study investigates the relationship between learning Braille with social inclusion and levels of independence. It also aims to raise awareness for the importance of pre-Braille learning and appropriate support for all learners, specifically those with special educational needs and disabilities (SEND). Participants range from children and young people (CYP) with visual impairments (VI) and/or SEND, to adults supporting learners with such difficulties.

Interviews were conducted with adult participants and a simplified questionnaire using a Likert scale questionnaire style approach was used with the CYP participants. The questionnaire was presented to participants with a selection of relatable faces to point to, indicating their level or agreement or disagreement. Alongside the empirical data gathered for this study, autoethnography was used to explore and provide an in-depth insight into the rationale and background for study, offering relevant and personal experience of living, learning, and teaching with a VI. An analysis of the findings demonstrates a link between implementing Braille from an early age and the impact upon levels of independence, as well as the positive effects upon social inclusion.The research process also highlights the need for a tactile pre-Braille learning system, aimed at supporting early years learners and SEND learners facing difficulties with touch sensitivity and fine motor skills. The study introduces a new learning system called ‘PRIOR’, which takes a simplified and enlarged tactile shape approach of Braille letter dot formations, enabling learners to grasp letters shapes independently or with support and explore then in their own unique ways. A recommendation from this study is that further research be conducted into the effectiveness of using a tactile simplified Braille letter shape approach, and to what extend this system can aid learners into becoming future Braille users.

Year: 2020

This Tutorial Slide Presentation: Medium voltage (MV) switchgear is a key element of the electrical energy distribution system. The Digital Switchgear concept, at the MV distribution level, presents many operational advantages and is inherently safe. It is based on the combination of technologies such as current and voltage sensors and IEC 61850 incorporated into modern numerical IEDs. When these technologies are combined in an optimal way the advantages of digital switchgear include increased safety, space, weight and energy savings, flexibility towards changing load flows, the ability to more easily handle last minute load changes, quicker delivery times and the possibility of late customization. In this tutorial, we will cover the background and characteristics of Digital Switchgear and contrast it with conventional switchgear. Two key component technologies, current and voltage sensors and IEC 61850 based protection and control will be covered in detail. The practical experiences gained from the early projects in the field will be presented.

We study in detail the pattern produced by adding grains on a two-dimensional square lattice with directed edges (each site has two arrows directed inward and two outward), starting with a periodic background with half the sites occupied. The size of the pattern formed scales with the number of grains added $N$ as $\sqrt{N}$. We give exact characterization of the asymptotic pattern, in terms of the position and shape of different features of the pattern.

description: Reliable measurement of droplet/bubble size and velocity distributions in dense flows is desired in a variety of research fields, both for laboratory and industrial use. A new type of single-mode monofiber optical probe manufactured by A2 Photonic Sensors is introduced in this paper: it combines traditional phase detection with the collection of a Doppler signal returned by an incoming gas-liquid interface to provide information on residence times, drop concentration and velocity, which afford then drop chords and liquid flux measurements. Compared with classical optical probes, that new sensor does not require any calibration. The purpose of the present work is to test this technique in assisted atomization in order to provide a mean for spray characterization and ultimately to improve our understanding of atomization mechanisms. The probe has been tested downstream of a coaxial air-assisted atomizer operated at liquid velocity =. to. / , and gas velocity from = to about /. We first analyzed raw signals in various flow conditions. It happens that, when increasing the gas velocity and the number density of drops, the signal experiences very strong fluctuations of the gas level, making the identification of individual droplets more difficult. That leads us to develop a new signal processing routine specifically adapted to such complex working conditions. At = / and for three liquid flow rates, the spatial integration of local liquid fluxes represents 92 to 99% of the injected liquid flow rate. These good results demonstrate that the Doppler probe provides reliable statistics on drops velocity and size.
Assessment of Measurement-Based Phase Identification Methods

The primary contributions of this paper are: i) A comparison of six state-of-the-art phase identification algorithms; ii) An additional set of results obtained from a real AMI data set; iii) A comprehensive literature review of the current state-of-the-art in phase identification methods.
The task of determining the phase connection of customers, known as phase identification, is crucial to obtain accurate distribution system models. This paper starts with a thorough literature review of the existing phase identification methods, which are broadly divided into three categories: hardware-based, real power-based, and voltage-based methods. This is followed by multiple case studies assessing the accuracy of six real power- and voltage-based phase identification algorithms on four realistic distribution test systems. Synthetic load profiles along with network models are used to quantify accuracy of each method for different scenarios: varying advanced metering infrastructure (AMI) coverage, number of initially mislabeled customer phases, number of available samples, and measurement noise. A case study using a real AMI data set, including field verification, is also provided. Finally, several aspects key to accurate phase identification are discussed in detail.

description: This paper explores the design of an interactive installation in a science center which facilitates an embodied experience with satellite data. This addresses a central concern for experience design in museums, which is the question of how to integrate technologies well in the visitor experience, sometimes referred to as "experience blend". We present the design and evaluation of a visualization triggered by movement in a physical staircase to let visitors explore data about satellites at different orbits. The evaluation demonstrates strong experience blend, and points towards similar design opportunities for other institutions interested in finding new uses for mundane pathways through their buildings.

description: We observe stationary random tessellations $X=\{Ξ_n\}_{n\ge1}$ in $\mathbb{R}^d$ through a convex sampling window $W$ that expands unboundedly and we determine the total $(k-1)$-volume of those $(k-1)$-dimensional manifold processes which are induced on the $k$-facets of $X$ ($1\le k\le d-1$) by their intersections with the $(d-1)$-facets of independent and identically distributed motion-invariant tessellations $X_n$ generated within each cell $Ξ_n$ of $X$. The cases of $X$ being either a Poisson hyperplane tessellation or a random tessellation with weak dependences are treated separately. In both cases, however, we obtain that all of the total volumes measured in $W$ are approximately normally distributed when $W$ is sufficiently large. Structural formulae for mean values and asymptotic variances are derived and explicit numerical values are given for planar Poisson--Voronoi tessellations (PVTs) and Poisson line tessellations (PLTs).

description: The Magellanic Clouds (MCs) offer an outstanding variety of young stellar associations, in which large samples of low-mass stars (with masses less than 1 solar mass) currently in the act of formation can be resolved and explored sufficiently with the Hubble Space Telescope. These pre-main sequence (PMS) stars provide a unique snapshot of the star formation process, as it is being recorded for the last 20 Myr, and they give important information on the low-mass Initial Mass Function (IMF) of their host environments. We present the latest results from observations with the Advanced Camera for Surveys (ACS) of such star-forming regions in the MCs, and discuss the importance of Hubble}for a comprehensive collection of substantial information on the most recent low-mass star formation and the low-mass IMF in the MCs.

description: Cet article vise à identifier les causes de la gestion inefficace des eaux pluviales dans la commune de Nzinda et à analyser les conséquences de ce déséquilibre environnemental. Les auteurs proposent des techniques durables pour lutter contre le ruissellement et l'érosion, ainsi qu'un plan de réaménagement et de gestion des eaux pluviales. La méthodologie comprend deux phases : d'abord, une enquête auprès de 396 parcelles pour recueillir les stratégies de gestion des eaux pluviales de la population, et ensuite des observations sur le terrain concernant les caniveaux, collecteurs, égouts et ravins. Les données ont été traitées avec Microsoft Excel 2019 et SPSS 26, et des cartes thématiques ont été créées avec ArcMap 10.8, QGIS Desktop 3.36 et Google Earth Pro. Les résultats montrent que parmi les 396 parcelles étudiées, 52 % des maisons n'ont pas de gouttières, 46 % n'ont pas de système de stockage, et 47 % n'ont pas de sol recouvert. La commune dispose de 21 caniveaux, 2 collecteurs et 3 égouts, souvent mal entretenus et sous-dimensionnés. Cela a conduit à la formation de 49 ravins actifs, causant une érosion sur 341 977 m², soit l'équivalent de 855 parcelles de 400 m². Environ 12 698 484 m³ de terre ont été érodés, représentant une perte de plus de 19 047 726 tonnes, entraînant des dommages environnementaux significatifs.
Computer simulation of phytoplankton and nutrient dynamics in an enclosed marine ecosystem
Creators: name: Carruthers, Alan Boyd
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents a quantitative model of interactions among phytoplankton, nutrients, bacteria and grazers in an enclosed marine ecosystem. The enclosed system was a 23 m deep, 9.6 m diameter column of surface water in Saanich Inlet, British Columbia. Dynamics of large- and small-celled diatoms and flagellates in response to observed irradiance and zooplankton numbers and observed or simulated nitrogen and silicon concentrations were modelled over a simulated 76-day period between July 12 and September 26. The model's predictions poorly matched the observed events in Controlled Experimental Ecosystem 2 (CEE2), but nevertheless provided some important insights into system behavior. Ciliate grazing probably prevented small-celled phytoplankton from increasing to large concentrations in CEE2. By virtue of their tremendous numbers, colourless flagellates were potentially the most important grazers on bacteria, much more important than larvaceans or metazoan larvae. Whereas small-celled phytoplankton were limited by grazers, large phytoplankton dynamics were not markedly affected by grazing. The average observed rate of 14C fixation in the surface 8 m was roughly consistent with an interpretation in which artificial additions of nitrogen contributed 62% of inferred net uptake of nitrogen by phytoplankton, mixing from subsurface water contributed 18%, bacterial remineralization 12%, and zooplankton excretion 9%. However, independent observations of rapid activity by microheterotrophs (presumably bacteria) suggested that 1*C fixation considerably underestimated net primary production. This yielded an alternative interpretation in which nutrient additions contributed 46% of inferred net uptake of nitrogen in the surface layer, mixing 13%, bacteria 35%, and zooplankton 7%. Dissolution of silica was responsible for the observed accumulation of silicic acid below 8 m depth in CEE2, but the importance of silica dissolution as a source of Si for diatom growth in the surface 8 m is uncertain. The model's major failing was its assumption of unchanging maximum growth rates of phytoplankton, and unchanging rates of exudation, sinking, and respiration. Physiological parameter values which accounted for the huge bloom of Stephanopyxis in CEE2 could not account for the ensuing collapse. Traditional modelling assumptions of slowly changing internal physiology, although adequate for marine systems dominated by physical factors such as seasonality or water movement, cannot capture the behavior of biologically dominated systems like the enclosed system considered here.

description: Despite the great popularity of virtual screening of existing compound libraries, the search for new potential drug candidates also takes advantage of generative protocols, where new compound suggestions are enumerated using various algorithms. To increase the activity potency of generative approaches, they have recently been coupled with molecular docking, a leading methodology of structure-based drug design. In this review, we summarize progress since docking-based generative models emerged. We propose a new taxonomy for these methods and discuss their importance for the field of computer-aided drug design. In addition, we discuss the most promising directions for further development of generative protocols coupled with docking.
Holographic Heat Engines Coupled with Logarithmic $U(1)$ Gauge Theory

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this paper we study a new class of holographic heat engines via charged AdS black hole solutions of Einstein gravity coupled with logarithmic nonlinear $U(1)$ gauge theory. So, Logarithmic $U(1)$ AdS black holes with a horizon of positive, zero and negative constant curvatures are considered as a working substance of a holographic heat engine and the corrections to the usual Maxwell field are controlled by non-linearity parameter $β$. The efficiency of an ideal cycle ($η$), consisting of a sequence of isobaric $\to$ isochoric $\to$ isobaric $\to$ isochoric processes, is computed using the exact efficiency formula. It is shown that $η/η_{C}$, with $η_{C}$ the Carnot efficiency (the maximum efficiency available between two fixed temperatures), decreases as we move from the strong coupling regime ($β\to 0$) to the weak coupling domain ($β\to \infty$). We also obtain analytic relations for the efficiency in the weak and strong coupling regimes in both low and high temperature limits. The efficiency for planar and hyperbolic logarithmic $U(1)$ AdS black holes is computed and it is observed that efficiency versus $β$ behaves in the same qualitative manner as the spherical black holes.

description: To study the microscopic electronic and magnetic interactions in the substoichiometric iron chalcogenide FeSe$_{1-x}$ which is observed to superconduct at x~1/8 up to $T_c$=27 K, we use first principles methods to study the Se vacancy in this nearly magnetic FeSe system. The vacancy forms a ferrimagnetic cluster of eight Fe atoms, which for the ordered x=1/8 alloy leads to half metallic conduction. Similar magnetic clusters are obtained for FeTe$_{1-x}$ and for BaFe$_2$As$_2$ with an As vacancy, although neither of these are half metallic. Based on fixed spin density results, we suggest the low energy excitations in FeSe$_{1-x}$ are antiparamagnon-like with short correlation length.
