Cost-Effective Bad Synchrophasor Data Detection Based on Unsupervised Time Series Data Analytics

description: In modern smart grids deployed with various advanced sensors, e.g., phasor measurement units (PMUs), bad (anomalous) measurements are always inevitable in practice. Considering the imperative need for filtering out potential bad data, this paper develops a novel online bad PMU data detection (BPDD) approach for regional phasor data concentrators (PDCs) by sufficiently exploring spatial-temporal correlations. With no need for costly data labeling or iterative learning, it performs model-free, label-free, and non-iterative BPDD in power grids from a new data-driven perspective of spatial-temporal nearest neighbor (STNN) discovery. Specifically, spatial-temporally correlated regional measurements acquired by PMUs are first gathered as a spatial-temporal time series (TS) profile. Afterwards, TS subsequences contaminated with bad PMU data are identified by characterizing anomalous STNNs. To make the whole approach competent in processing online streaming PMU data, an efficient strategy for accelerating STNN discovery is carefully designed. Different from existing data-driven BPDD solutions requiring either costly offline dataset preparation/training or computationally intensive online optimization, it can be implemented in a highly cost-effective way, thereby being more applicable and scalable in practical contexts. Numerical test results on the Nordic test system and the realistic China Southern Power Grid demonstrate the reliability, efficiency and scalability of the proposed approach in practical online monitoring.

description: We analyze the theoretical framework of a shape optimization problem for a microchannel cooling system. To this end, a cost functional based on the tracking of absorbed energy by the cooler as well as some desired flow on a subdomain of the cooling system is introduced. The flow and temperature of the coolant are modeled by a Stokes system coupled to a convection diffusion equation. We prove the well-posedness of this model on a domain transformed by the speed method. Further, we rigorously prove that the cost functional of our optimization problem is shape differentiable and calculate its shape derivative by means of a recent material derivative free adjoint approach.

description: This paper continue earlier investigations on the decay of Burgers turbulence in one dimension from Gaussian random initial conditions of the power-law spectral type $E_0(k)\sim|k|^n$. Depending on the power $n$, different characteristic regions are distinguished. The main focus of this paper is to delineate the regions in wave-number $k$ and time $t$ in which self-similarity can (and cannot) be observed, taking into account small-$k$ and large-$k$ cutoffs. The evolution of the spectrum can be inferred using physical arguments describing the competition between the initial spectrum and the new frequencies generated by the dynamics. For large wavenumbers, we always have $k^{-2}$ region, associated to the shocks. When $n$ is less than one, the large-scale part of the spectrum is preserved in time and the global evolution is self-similar, so that scaling arguments perfectly predict the behavior in time of the energy and of the integral scale. If $n$ is larger than two, the spectrum tends for long times to a universal scaling form independent of the initial conditions, with universal behavior $k^2$ at small wavenumbers. In the interval $2

description: Globally is wasted about one third of total food produced per year. The losses are borne along the entire food chain from “farm to fork”. The phenomenon requires an analysis and monitoring of the impact due to continuous development of food sector. Food losses and its waste have an impact on the sustainability of food systems in all three dimensions: economic, social and environmental. Irrational use of food beyond the amount of losses, is a threat to our environment because of excessive consumption of natural resources and is a causes of unmet nutritional needs of societies. The aim of the study was to determine the causes of losses and wastage in the food chain and categorization as well as taking into account recovery capabilities. As follows from the analysis presented in the work some of the reasons for food losses and waste are well known, possible limitations. Therefore, we should seek ways of recovering of food products and using them as intended. One way may be the transfer of food for social purposes, which also affects the sustainability of development in this sector due to social aspects.

A General Theory of Non-equilibrium Dynamics of Lipid-protein Fluid Membranes

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We present a general and systematic theory of non-equilibrium dynamics of multi-component fluid membranes, in general, and membranes containing transmembrane proteins, in particular. Developed based on a minimal number of principles of statistical physics and designed to be a meso/macroscopic-scale effective description, the theory is formulated in terms of a set of equations of hydrodynamics and linear constitutive relations. As a particular emphasis of the theory, the equations and the constitutive relations address both the thermodynamic and the hydrodynamic consequences of the unconventional material characteristics of lipid-protein membranes and contain proposals as well as predictions which have not yet been made in already existed work on membrane hydrodynamics and which may have experimental relevance. The framework structure of the theory makes possible its applications to a range of non-equilibrium phenomena in a range of membrane systems, as discussions in the paper of a few limit cases demonstrate.

description: The magnetic properties of the first odd-member antiferromagnetic ring comprising eight chromium(III) ions, S=3/2 spins, and one nickel(II) ion, S=1 spin, are investigated. The ring possesses an even number of unpaired electrons and a S=0 ground state but, due to competing AF interactions, the first excited spin states are close in energy. The spin frustrated ring is visualized by a Moebius strip. The ?knot? of the strip represents the region of the ring where the AF interactions are more frustrated. In the particular case of this bimetallic ring electron paramagnetic resonance (EPR) has unambiguously shown that the frustration is delocalized on the chromium chain, while the antiparallel alignment is more rigid at the nickel site.

description: Probabilistic convolutional neural networks, which predict distributions of predictions instead of point estimates, led to recent advances in many areas of computer vision, from image reconstruction to semantic segmentation. Besides state of the art benchmark results, these networks made it possible to quantify local uncertainties in the predictions. These were used in active learning frameworks to target the labeling efforts of specialist annotators or to assess the quality of a prediction in a safety-critical environment. However, for instance segmentation problems these methods are not frequently used so far. We seek to close this gap by proposing a generic method to obtain model-inherent uncertainty estimates within proposal-free instance segmentation models. Furthermore, we analyze the quality of the uncertainty estimates with a metric adapted from semantic segmentation. We evaluate our method on the BBBC010 C.\ elegans dataset, where it yields competitive performance while also predicting uncertainty estimates that carry information about object-level inaccuracies like false splits and false merges. We perform a simulation to show the potential use of such uncertainty estimates in guided proofreading.

They offer a compact device footprint, very high versatility, large numbers of wavelengths, and wide Nyquist bands. Here, we review recent progress on Kerr microcomb-based photonic RF and microwave reconfigurable filters, based both on transversal filter methods and on RF to optical bandwidth scaling. We compare and contrast results achieved with wide comb spacing combs (200GHz) with more finely spaced (49GHz) microcombs. The strong potential of optical micro-combs for RF photonics applications in terms of functions and integrability is also discussed.

They aimed initial identifi cation of cows reaction on changing of THI, which are likened to temperature and humidity conditions of air. The subjected cows characterize with high productivity, exceeding 40kg of milk per day, independently from lactation stages. The results display that the day s production of raw milk, as well as fat and protein content, do not only depend on lactation stage but also on the value of THI factors. Higher THI is accompanied by loss in the weight of milk and drop in its technological utility. The climate warming may escalate the risk of production loss during the heats.

Considerations are based on a new direct method, exploiting \textit{almost orthogonality} of Birkhoff's solutions of the equation $l(y)=λy$, which was discovered earlier by the author.

Cue-recognition mechanisms and person perception
Creators: name: Park, Justin H.
Publisher: name: University of British Columbia
Year: 2010

description: Our different responses to different individuals depend on psychological mechanisms that detect specific kinds of people and produce context-appropriate cognitions and emotions. These mechanisms often respond to heuristic cues (e.g., symmetry) that may signal some underlying information (e.g., health). Many cue-recognition mechanisms may be usefully understood as evolved adaptations that served specific functions in ancestral environments. These mechanisms may operate in a wide range of situations in contemporary contexts, which may help us better understand many aspects of social cognition. In this dissertation, I describe mechanisms of kin recognition and parasite recognition, and I describe empirical studies that tested some of the implications of these mechanisms. One study tested the hypothesis that attitude similarity may serve as a heuristic kinship cue. The results showed that the perception of an attitudinally similar other may activate kinship-relevant cognitions, which may enhance prosocial motivations. A second study tested the hypothesis that physical disabilities may serve as a heuristic parasite cue. Although the results showed that disabilities may activate disease-relevant cognitions, the evidence for the hypothesis was not strong. Finally, a set of studies tested the hypothesis that obesity may serve as a heuristic parasite cue. The results showed that people may be especially motivated to avoid physical (versus nonphysical) contact with obese individuals; that chronically heightened concerns about parasites are positively correlated with dislike of fat people; and that the perception of obesity may activate disease-relevant cognitions, especially when the threat of parasites has been made salient. I discuss some of the broader implications as well as the methodological limitations.

description: The COVID-19 pandemic presents global challenges transcending boundaries of country, race, religion, and economy. The current gold standard method for COVID-19 detection is the reverse transcription polymerase chain reaction (RT-PCR) testing. However, this method is expensive, time-consuming, and violates social distancing. Also, as the pandemic is expected to stay for a while, there is a need for an alternate diagnosis tool which overcomes these limitations, and is deployable at a large scale. The prominent symptoms of COVID-19 include cough and breathing difficulties. We foresee that respiratory sounds, when analyzed using machine learning techniques, can provide useful insights, enabling the design of a diagnostic tool. Towards this, the paper presents an early effort in creating (and analyzing) a database, called Coswara, of respiratory sounds, namely, cough, breath, and voice. The sound samples are collected via worldwide crowdsourcing using a website application. The curated dataset is released as open access. As the pandemic is evolving, the data collection and analysis is a work in progress. We believe that insights from analysis of Coswara can be effective in enabling sound based technology solutions for point-of-care diagnosis of respiratory infection, and in the near future this can help to diagnose COVID-19.

description: We investigate the time autocorrelation of the molecular magnetization $M(t)$ for three classes of magnetic molecules (antiferromagnetic rings, grids and nanomagnets), in contact with the phonon heat bath. For all three classes, we find that the exponential decay of the fluctuations of $M(t)$, associated with the irreversible exchange of energy with the heat bath, is characterized by a single characteristic time $τ(T,B)$ for not too high temperature $T$ and field $B$. This is reflected in a nearly single-lorentzian shape of the spectral density of the fluctuations. We show that such fluctuations are effectively probed by NMR, and that our theory explains the recent phenomenological observation by Baek et al. (PRB70, 134434) that the Larmor-frequency dependence of $1/T_1$ data in a large number of AFM rings fits to a single-lorentzian form.

Evidence for electroweak production of four charged leptons and two jets in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Evidence is presented for the electroweak (EW) production of two jets (jj) in association with two Z bosons and constraints on anomalous quartic gauge couplings are set. The analysis is based on a data sample of proton-proton collisions at $\sqrt{s} = $ 13 TeV collected with the CMS detector in 2016-2018, and corresponding to an integrated luminosity of 137 fb$^{-1}$. The search is performed in the fully leptonic final state ZZ $\to$ $\ell\ell\ell'\ell'$, where $\ell,\ell' = $ e, $μ$. The EW production of two jets in association with two Z bosons is measured with an observed (expected) significance of 4.0 (3.5) standard deviations. The cross sections for the EW production are measured in three fiducial volumes and the result is $σ_{\mathrm{EW}}$(pp $\to$ ZZjj $\to$ $\ell\ell\ell'\ell'$jj) = 0.33 $^{+0.11}_{-0.10}$ (stat) $^{+0.04}_{-0.03}$ (syst) fb in the most inclusive volume, in agreement with the standard model prediction of 0.275 $\pm$ 0.021 fb. Measurements of total cross sections for jj production in association with two Z bosons are also reported. Limits on anomalous quartic gauge couplings are derived in terms of the effective field theory operators T0, T1, T2, T8, and T9.

description: The article presents the results of a study which aims to determine the effect of the number of industrial vertical linkages and participation in the supply chain on innovation activity of food industry in western Poland. The main research hypothesis is the assumption that innovation processes in food industry are strongly determined by the intensity and nature of the linkages and membership in the supply chain. The scope of the survey relates to innovation in food industry, concerns innovation at the company level and takes into account the diffusion to the “new to the company”. Innovative activities are divided into three general groups including: expenditure on research and development and investments in fi xed assets not used so far (such as: buildings, premises and land, machinery and equipment, computer software), implementation of new products and processes, and innovative collaboration. The survey covers 422 industrial enterprises. The methodological part of the study uses probit modelling that enables to identify the probability of occurrence of innovation activity.
Globular cluster systems and galaxy formation

description: Globular clusters are compact, gravitationally bound systems of up to a million stars. The GCs in the Milky Way contain some of the oldest stars known, and provide important clues to the early formation and continuing evolution of our Galaxy. More generally, GCs are associated with galaxies of all types and masses, from low-mass dwarf galaxies to the most massive early-type galaxies which lie in the centres of massive galaxy clusters. GC systems show several properties which connect tightly with properties of their host galaxies. For example, the total mass of GCs in a system scales linearly with the dark matter halo mass of its host galaxy. Numerical simulations are at the point of being able to resolve globular cluster formation within a cosmological framework. Therefore, GCs link a range of scales, from the physics of star formation in turbulent gas clouds, to the large-scale properties of galaxies and their dark matter. In this Chapter we review some of the basic observational approaches for GC systems, some of their key observational properties, and describe how GCs provide important clues to the formation of their parent galaxies.

description: The main purpose of the article is to present economic and legal aspects of payment backlogs in commercial transactions. In terms of economic aspects, the study focuses on the structure and cycle diversity of corporate receivables, payment terms and the scale of losses caused by late payments in the chosen European countries. The analysis was based on the data presented in the reports of the multinational information agency Intrum Justitia. The study shows that paying credibility in European countries is strongly diversifi ed. The most reliable and favourable situation regarding the analysed aspect should be enjoyed by the Scandinavian countries, Finland, Island and Switzerland. In turn, the least stable situation and gravest problems relating paying credibility occurred in the Southern European countries, especially in Greece, Bosnia and Herzegovina, Portugal, Croatia, Bulgaria, Serbia, Romania and Cyprus. The legal aspects of the payment backlogs were analysed on the ground of both EU and domestic law. The brief characteristics of both Directive 2000/35/EC of 29.6.2000 on combating late payment in commercial transactions and Directive 2011/7/EU of 16.02.2011 on combating late payment in commercial transactions was presented in the article. Furthermore, the article contains a brief analysis of the domestic Act of 8.03.2013 – Payments Terms in Commercial Transaction.

description: Sterile neutrinos coupling only to third-generation fermions are attractive dark matter candidates. In an EFT approach we demonstrate that they can generate the observed relic density without violating constraints from direct and indirect detection. Such an EFT represents a gauged third-generation $B-L$ model, as well as third-generation scalar or vector leptoquarks. LHC measurements naturally distinguish the different underlying models.

description: Monte Carlo techniques based on indivisible energy packets are described for computing light curves and spectra for 3-D supernovae. The radiative transfer is time-dependent and includes all effects of O(v/c). Monte Carlo quantization is achieved by discretizing the initial distribution of 56Ni into radioactive pellets. Each pellet decays with the emission of a single energy packet comprising gamma-ray photons representing one line from either the 56Ni or the 56Co decay spectrum. Subsequently, these energy packets propagate through the homologously-expanding ejecta with appropriate changes in the nature of their contained energy as they undergo Compton scatterings and pure absorptions. The 3-D code is tested by applying it to a spherically-symmetric SN in which the transfer of optical radiation is treated with a grey absorption coefficient. This 1-D problem is separately solved using Castor's co-moving frame moment equations. Satisfactory agreement is obtained. The Monte Carlo code is a platform onto which more advanced treatments of the interactions of matter and radiation can be added. Some of these have already been developed and tested in previous papers and are summarized here.

description: The Advanced Molybdenum-based Rare process Experiment (AMoRE) searches for neutrino-less double-beta (0ν\b{eta}\b{eta}) decay of 100Mo in enriched molybdate crystals. The AMoRE crystals must have low levels of radioactive contamination to achieve low background signals with energies near the Q-value of the 100Mo 0ν\b{eta}\b{eta} decay. To produce low-activity crystals, radioactive contaminants in the raw materials used to form the crystals must be controlled and quantified. 100EnrMoO3 powder, which is enriched in the 100Mo isotope, is of particular interest as it is the source of 100Mo in the crystals. A high-purity germanium detector having 100% relative efficiency, named CC1, is being operated in the Yangyang underground laboratory. Using CC1, we collected a gamma spectrum from a 1.6-kg 100EnrMoO3 powder sample enriched to 96.4% in 100Mo. Activities were analyzed for the isotopes 228Ac, 228Th, 226Ra, and 40K. They are long-lived naturally occurring isotopes that can produce background signals in the region of interest for AMoRE. Activities of both 228Ac and 228Th were < 1.0 mBq/kg at 90% confidence level (C.L.). The activity of 226Ra was measured to be 5.1 \pm 0.4 (stat) \pm 2.2 (syst) mBq/kg. The 40K activity was found as < 16.4 mBq/kg at 90% C.L.

description: The effects of salt stress on the morphology, growth and physiology of Amaronthus dubious [eallaloo] and Capsicum chinense [var. scotch bonnet pepper] were investigated. Various concentrations of sea salt have been used to obtain different salinity levels ofthe soil from 0 to 10 dS m-I • Low levels of salinity at 2 dS m" actually enhanced the growth ofthe plants as measured by the shoot height. Concentrations higher than this inhibited the growth of callaloo. For pepper, salinity level of 4.0 dS rn" was also not that inhibitory. However, salt levels above that level inhibited growth and the older leaves first turned yellowish in colour. There was a positive correlation between the increase in the level ofproline in the plant tissues and salt concentration. Proline content was higher in the shoot than the root. Soluble carbohydrates increased with increasing salinity levels in both callaloo and pepper. The protein levels decreased with increasing salinity levels in eallaloo but remained unchanged in pepper. The activity ofthe enzyme nitrate reductase was inhibited above concentrations of4.0 dS. rn' in both plants and the inhibition was severe in the roots. The results indicate that eallaloo is more sensitive to salt stress than scotch bonnet pepper and slightly different mechanisms are involved in the salt tolerance in callaloo and pcpper.

description: Schwinden als eine Volumenänderung des porösen Baustoffs, die nicht durch eine Lastwirkung, sondern durch die Änderung des Wasserhaushaltes verursacht ist, spielt eine wichtige Rolle im Betonbau. Das Schwinden von Beton wurde in vielen Arbeiten untersucht, wobei meistens eine Längenänderung oder Spannung infolge von Schwinden gemessen wurde. Die Frage, wie groß die Kräfte die das Schwinden verursachen sind, bleibt jedoch ungeklärt. Ziel der Arbeit ist deshalb eine Messvorrichtung herzustellen, die diese Kräfte direkt messen kann, um neue Erkenntnisse im Hinblick auf die dadurch entstehende Rissgefahr zu erlangen. In mehreren experimentellen Versuchsreihen wurden erstmals verschiedene Varianten der Messvorrichtung getestet, bis eine wiederholbare Messung möglich war. Die Einflüsse der Zementsorten auf die Schwindkräfte konnten mit dieser Messmethode charakterisiert werden. Dabei wurden neben der Druckfestigkeit im Rahmen der Versuchsreihen auch der Elastizitätsmodul und eine Struktur des Zementsteins an der Bruchfläche untersucht und interpretiert.
description: Shrinkage as a change in volume of the porous material that is not caused by a load, but by the change of the water balance, plays an important role in concrete construction. Current research has focused on length elongation or tension of concrete during the process of shrinkage. The question of the influencing forces has not been researched until now. Aim of this thesis is to develop an direct measurement mechanism of the shrinkage forces. Gathering knowledge in danger of crack initiation is the major goal. In many experimental runs several types of measurement devices are testest until a repeatable result is reached. This specific measurement method characterizes the influences of cement types on the shrinkage forces. The studies analyzes the pressure resistance, elastic modulus and the structure of the cement stone on the fractured surface.

description: We reconsider the unified model of gravitation and Yang--Mills interactions proposed by Chakraborty and Peldán, in the light of recent formal developments in loop quantum gravity. In particular, we show that one can promote the Hamiltonian constraint of the unified model to a well defined anomaly-free quantum operator using the techniques introduced by Thiemann, at least for the Euclidean theory. The Lorentzian version of the model can be consistently constructed, but at the moment appears to yield a correct weak field theory only under restrictive assumptions, and its quantization appears problematic.

description: Peanut plants, cvs 'Georgia Red' (GARBO) andNew Improved Spanish (NISP), were grown in polyvinyl chloride (PVC-I) trays using the nutrient film technique to study pod and seed yield for NASA's Advanced Life Support (ALS) program. Four 14-day-old seedlings each of both genotypes were transplanted into each of two growth trays (0.15 x 0.15 x 1.2 m), allotting 0.045 m2 per plant for growth. Plants were grown in reach-in growth chambers with a diurnal temperature of28/22°C, relative hwnidity of70 +5%, 12/12 h photoperiod, irradiance at canopy Icvel of 600 ?mol m-2 s-I, and a C02 concentration of 700 ?mol mol-L A modified half Hoagland nutrient solution was used. Solution pH was adjusted manually and ranged between 6.4 and 6.7, by additions of 1M NaOIl or HCI. Solution electrical conductivity (EC) ranged between 1100 and 1200 ?S em-I. All plants were harvested after 120 days. Total mean plant fresh weight was 546.5 g and 769.0 g per tray, respectively, for Georgia Red and New Improved Spanish. The total number ofpods and pod fresh weight per tray averaged 152 and 190 g forGR and 138 and 154 g for NISP, while seed dry mass averaged 70 g and 81 gper tray, respectively, for GAREO and NIS. The harvest index was 0.39 for GR and 0.36 for NISP. Seed yield was equivalent to or exceeded that of field-grown peanuts. Generally, the proximate nutrient composition was similar to that of field-grown peanuts. The results demonstrate that the nutrient film technique CBLn be used for peanut production with acceptable yields.
