An Energy-Efficient, Parallel Neighborhood and Adaptation Functions for Hardware Implemented Self-Organizing Maps Applied in Smart Grid

Smart Grids (SGs) can be successfully supported by Wireless Sensor Networks (WSNs), especially through these consisting of intelligent sensors, which are able to efficiently process the still growing amount of data. We propose a contribution to the development of such intelligent sensors, which in an advanced version can be equipped with embedded low-power artificial neural networks (ANNs), supporting the analysis and the classification of collected data. This approach allows to reduce the energy consumed by particular sensors during the communication with other nodes of a larger WSN. This in turn, facilitates the maintenance of a net of such sensors, which is a paramount feature in case of their application in SG devices distributed over a large area. In this work, we focus on a novel, energy-efficient neighborhood mechanism (NM) with the neighborhood function (NF). This mechanism belongs to main components of self learning ANNs. We propose a realization of this component as a specialized chip in the CMOS technology and its optimization in terms of the circuit complexity and the consumed energy. The circuit was realized as a prototype chip in the CMOS 130 nm technology, and verified by means of transistor level simulations and measurements.
The existence, general decay and blow-up for a plate equation with nonlinear damping and a logarithmic source term

In this paper, we consider a plate equation with nonlinear damping and logarithmic source term. By the contraction mapping principle, we establish the local existence. The global existence and decay estimate of the solution at subcritical initial energy are obtained. We also prove that the solution with negative initial energy blows up in finite time under suitable conditions. Moreover, we also give the blow-up in finite time of solution at the arbitrarily high initial energy for linear damping (i.e. \begin{document}$ m = 2 $\end{document} ).
Rising Stars: Competitive Balance in Five Asian Football Leagues

Abstract Competitive balance (CB) remains a core component of sport economics literature and an important management consideration for league organisers. This paper analyses CB in the ‘big five’ Asian football leagues longitudinally between 1996/97 and 2017/18. Using recognised measures of league concentration and dominance, the results display a mixed picture in respect of CB across the five major leagues in Asian football. The Asian football market has seen positive growth during the last two decades while CB in most of the leagues examined has remained relatively stable. Some significant differences were detected in the levels of concentration between leagues. There was also some variation in terms of some leagues being dominated by a fewer number of teams. However, these two measures of CB (concentration and dominance) were not necessarily correlated with each other. In a broader governance context, questions remain over the potential for further growth in the Asian football market given the dominant market position of the European game.

Corporate Control Around the World

We provide an anatomy of corporate control around the world after tracing controlling shareholders for thousands listed firms from 127 countries between 2004 and 2012. The analysis reveals considerable and persistent differences across and within regions, as well as across legal families. Government and family control is pervasive in civil-law countries. Equity blocks in widely-held corporations are commonplace, but less so in common-law countries. These patterns apply to large, medium, and small listed firms. In contrast, the association between income and corporate control is highly heterogeneous; the correlation is strong among big and especially very large firms, but absent for medium and small listed firms. We then examine the association between corporate control and various institutional features. Shareholder rights against insiders' self-dealing activities correlate strongly with corporate control, though legal formalism and creditor rights less so. Corporate control is strongly related to labor market regulations, concerning, among others, the stringency of employment contracts, the power and extent of unions. The large sample correlations, thus, offer support to both legal origin and political-development theories of financial development.
Circular-Looking Makes Green-Buying: How Brand Logo Shapes Influence Green Consumption

Despite the development of green products, convincing consumers to engage in green consumption is still a difficult task. This research attempts to help solve this problem from the perspective of brand logo design. Specifically, this research explores how circular and angular logo shapes influence green consumption. Three studies provide support for our basic prediction that a circular (vs. angular) logo is more effective in promoting green consumption. Self-construal plays a mediating role in this mechanism. However, the logo shape effect disappears when consumers are primed with high sense of power. When taken together, this research not only has theoretical contributions to green consumption and visual marketing, it also provides practical implications for firms manufacturing green products.
Using social media to improve temporary migrant workers' access to information about their employment rights

The exploitation of temporary migrant workers (TMWs) employed in Australia has been well documented by academics, government enquiries, and the Fair Work Ombudsman [FWO], the Federal government agency responsible for enforcing wage compliance. That exploitation encompasses underpayment of wages through to unpaid wages, and includes exposure to occupational health and safety risks, sexual harassment, overcrowded and unhygienic accommodation facilities, wage deduction scams, and a failure to provide income support to injured TMWs (Doyle and Howes 2015; Australian Senate 2016; FWO 2016; Mares 2016; Underhill and Rimmer 2016; Victorian Government 2016; Berg and Farbenblum 2017; Clibborn 2018; Howe et al. 2018). In horticulture, the rapid increase in TMWs following the expansion of the Working Holiday Visa scheme in 2005, and the expansion in the supply of undocumented workers has combined to produce a workforce which is easily exploited. Rural employment has traditionally been difficult for trade unions to organise, and these difficulties are compounded with TMWs, many of whom face significant language barriers and have a poor understanding of Australian employment rights.
Knowledge, Attitude and Perception of Risk and Preventive Behaviors toward Premarital Sexual Practice among In-School Adolescents

Premarital Sexual Practice (PSP) among adolescents usually involves sexually risky behaviors, such as multiple sexual partners and inconsistent or non-condom use. These behaviors, in combination with other underlining factors, undermine the overall outcomes of Adolescent Sexual and Reproductive Health (ASRH). To assess the adolescents’ knowledge, attitudes and perception of risk and preventive behaviors towards PSP, a school-based analytical cross-sectional study was conducted among a sample of 423 students aged 15 through 19 years. A well-validated anonymous self-administered questionnaire was used for collecting the data, which were analyzed using mean (SD), frequency (%), t-test, ANOVA and multiple regression methods. Participants’ knowledge of risk and preventive behaviors was average, as only 53% of knowledge items were correctly answered. Being a female, of high-income status, in the second study year, perceived susceptibility and perceived severity were significant determinants of knowledge. All measures of perception except perceived self-efficacy were positive determinants of attitude. Being female, in the third study year and of high-income status were determinants of perception as measured by perceived self-efficacy. Therefore, our results suggest that tailored educational programs, with special emphasis on financially disadvantaged male adolescents, are needed to effectively increase adolescents’ knowledge, attitude and perception of risk and protective behaviors towards PSP.
Risk assessment of aflatoxins in food

Abstract EFSA was asked to deliver a scientific opinion on the risks to public health related to the presence of aflatoxins in food. The risk assessment was confined to aflatoxin B1 (AFB1), AFB2, AFG1, AFG2 and AFM1. More than 200,000 analytical results on the occurrence of aflatoxins were used in the evaluation. Grains and grain‐based products made the largest contribution to the mean chronic dietary exposure to AFB1 in all age classes, while ‘liquid milk’ and ‘fermented milk products’ were the main contributors to the AFM1 mean exposure. Aflatoxins are genotoxic and AFB1 can cause hepatocellular carcinomas (HCCs) in humans. The CONTAM Panel selected a benchmark dose lower confidence limit (BMDL) for a benchmark response of 10% of 0.4 μg/kg body weight (bw) per day for the incidence of HCC in male rats following AFB1 exposure to be used in a margin of exposure (MOE) approach. The calculation of a BMDL from the human data was not appropriate; instead, the cancer potencies estimated by the Joint FAO/WHO Expert Committee on Food Additives in 2016 were used. For AFM1, a potency factor of 0.1 relative to AFB1 was used. For AFG1, AFB2 and AFG2, the in vivo data are not sufficient to derive potency factors and equal potency to AFB1 was assumed as in previous assessments. MOE values for AFB1 exposure ranged from 5,000 to 29 and for AFM1 from 100,000 to 508. The calculated MOEs are below 10,000 for AFB1 and also for AFM1 where some surveys, particularly for the younger age groups, have an MOE below 10,000. This raises a health concern. The estimated cancer risks in humans following exposure to AFB1 and AFM1 are in‐line with the conclusion drawn from the MOEs. The conclusions also apply to the combined exposure to all five aflatoxins.

Over the last 20 years due to advancements in the nanotechnology and targeting cell receptors, radionuclide therapies have emerged as a subspecialty of nuclear medicine. Through this article, we would like to briefly describe the evolution of radionuclide therapies and their different clinical applications as personalized medicine.
Debates: Does Information Theory Provide a New Paradigm for Earth Science? Sharper Predictions Using Occam's Digital Razor

Occam's Razor is a bedrock principle of science philosophy, stating that the simplest hypothesis (or model) is preferred, at any given level of model predictive performance. A modern restatement often attributed to Einstein explains, “Everything should be made as simple as possible, but not simpler. ” Using principles from (algorithmic) information theory, both model descriptive performance and model complexity can be quantified in bits. This quantification yields a Pareto‐style trade‐off between model complexity (length of the model program in bits) and model performance (information loss in bits, or the missing information, needed to describe the original observations). Model complexity and performance can be collapsed to one single measure of lossless model size, which, when minimized, leads to optimal model complexity versus loss trade‐off for generalization and prediction. Our view puts both simple data‐driven and complex physical‐process‐based models on a continuum, in the sense that both describe patterns in observed data in compressed form, with different degrees of generality, model complexity, and descriptive performance. Information theory‐based assessment of compression performance with fair and meaningful accounting for model complexity will enable us to best compare and combine the strengths of physics knowledge and data‐driven modeling for a given problem, given the availability of data.
On Geodesic Behavior of Some Special Curves

In this paper, geometric structures on an open subset D ⊆ R 2 are investigated such that the graphs associated with the solutions of some special functions to become geodesics. More precisely, we determine the Riemannian metric g such that Bessel (Hermite, harmonic oscillator, Legendre and Chebyshev) ordinary differential equation (ODE) is identified with the geodesic ODEs produced by the Riemannian metric g . The technique is based on the Lagrangian (the energy of the curve) L = 1 2 ‖ x ˙ ( t ) ‖ 2 , the associated Euler–Lagrange ODEs and their identification with the considered special ODEs.
Effects of dietary protein on growth performance, nutrient utilization, digestive enzymes and physiological status of grey mullet,Mugil cephalusL. fingerlings reared in inland saline water

A 60 days feeding trial was conducted to illustrate the effect of graded levels of protein on the growth and metabolic enzymes of grey mullet (Mugil cephalus L.) fingerlings reared in inland saline water (ISW). Six isoenergetic (16 MJ/kg) and isolipidic (60 g/kg) diets containing 240, 260, 280, 300, 320 and 340 g crude protein (CP)/kg diet were formulated and fed to triplicate. Weight gain %, specific growth rate, protein utilizing efficiency, feed efficiency and RNA:DNA ratio were significantly higher (p .05) variations were observed for lactate dehydrogenase, oxidative stress enzymes, blood parameters and serum osmolality among all the treatment groups, but red blood cell count increases with increasing dietary CP levels. Based on the results, feeding dietary protein level of 300 g CP/kg is economically viable for rearing of grey mullet in ISW.
The olfactory mucosa of river catfish, Eutropiichthys vacha (Hamilton, 1822): Histochemical studies

Miscellany in histochemical peculiarity of the olfactory mucosa was studied for localization of axons, mucopolysaccharides, glycogen, protein and lipid in schilbid catfish, Eutropiichthys vacha (Hamilton, 1822). Silver deposition was detected in the abundance of receptor cells in the olfactosensory epithelium and well as marked in the knob and dendrite process of primary receptor cells. The mucous cells with various stages of maturity containing different degrees of mucopolysaccharides were identified by employing the Periodic Acid Schiff's (PAS) reaction in combination with Alcian Blue (AB) test. This combined test imparted purple colour due to PAS for neutral mucin and blue colour for AB reaction due to the presence of acid mucin exclusively. The results of Best’s carmine test indicated considerable amount of glycogen present in the receptor cells, basal cells and supporting cells in the olfactory mucosa. Basic protein and bound lipid were ascertained in the various cells of the epithelial lining and in blood cells of the central core were discussed with behavioural activities of the fish interested.
The Architecture and Evolution of the Singhbhum Craton

The Singhbhum Craton is built up by successive pulses of discrete granitic magmatism at ~3.52 Ga, ~3.47-3.43 Ga, and ~3.40-3.35 Ga that produced tonalitetrondhjemite-granodiorite (TTG)-type suites and were followed by younger pulses at 3.32-3.35 Ga, and 3.313. 28 Ga producing voluminous granitic-granodioritic magma. There is enough evidence to indicate that continental crust building activity started in the Hadean time and continued through Eoarchean. But the rocks of this period were fully recycled to generate the Paleoarchean and younger crust. The different pulses of granitic magmatism during the Paleoarchean were interspersed with the formation of supracrustal rocks which are now preserved as supracrustal belts peripheral to the craton or as internal screens within the craton. Halfnium isotopic record suggests that the Hadean and Eoarchean granitoids were sourced in an enriched reservoir, probably some form of early mafic protocrust. From ~3.6-3.5 Ga a shift in the isotopic composition of Hf is noticed, marked by upward excursion of εHf(t) plots towards suprachondritic values, signifying that the early mantle reservoir was serially modified by contamination by a juvenile melt derived from a depleted source. This probably signals a change in the geodynamic scenario, major depletion of the mantle and generation of voluminous TTG melts. There are contending hypotheses of plume-driven and subduction-driven mechanisms of continental crust formation. In the Singhbhum Craton during Hadean and Eoarchean times episodic mantle plumes probably operated in a stagnant lid tectonic setting. Repeated plume activities and the formation of oceanic plateaus might have triggered the onset of subduction which at the initial stages might have been of short duration. The transition from plume-driven tectonics to subduction-driven tectonics might have taken place at about 3.5 Ga. The supracrustal belts of the Older Metamorphic Group (OMG) and the Iron Ore Group (IOG) are thought to have formed in supra-subduction settings. Widespread metamorphism and deformation affected the craton during 3.34-3.26 Ga. By 3.1 Ga the Singhbhum Craton had stabilized and emerged as a landmass. Paleosols developed on the surface; rift basins were formed which were receptacles of siliciclastic sediments and mafic volcanics; anorogenic K-feldspar bearing granites were emplaced. Swarms of mafic dykes of Paleoto Meso-Proterozoic age intruded the craton marking a tensional regime that was probably related to the initial stage of basin formation in the North Singhbhum Mobile Belt.
Celestial Spectra Classification Network Based on Residual and Attention Mechanisms

In astronomy, it is important to categorize celestial bodies by classifying collected spectral data. The currently available methods present unsatisfactory spectral classification accuracy and incur high computing costs. We propose a celestial spectral classification network based on a residual and attention based convolutional network (RAC-Net). In this network, convolution operations can extract shallow and deep features of spectral data and classify them without relying on redshifts. The residual mechanism can augment the depth of the network and make training more efficient. The attention mechanism allows the network to focus on specific bands and specific features, rendering the learning more targeted. To evaluate the performance of the RAC-Net, we conducted a comparative test using a celestial spectral data set that consisted of 70,000 spectra collected by the large sky area multi-object fiber spectroscopic telescope. The experimental results showed that the classification accuracy of our network was up to 98.92%. Compared with the leading one-dimensional, convolutional neural network 1D SSCNN model, the RAC-Net presented higher classification accuracy and fewer network parameters.
Perceived Effort, Satisfaction and Performance Times during a Mime and Drama Unit of Study

The objectives of this study were to describe, taking student age into account, the perceived effort, satisfaction, useful time and available time in a mime and drama unit of study in primary education students and also to analyse intersession variability and the association between the different variables. The results of this paper show that students experience a low perceived effort (2.48 ± 2.33 out of 10) but high satisfaction (3.52 ± 2.68 on a -5 to +5-point scale) during mime and drama sessions in the body expression block. Moreover, of the 90 minutes of weekly physical education included in the official syllabus, the average useful time per session was 53.22 ± 10.52 min per week (58% of total time), of which only 27.06 ± 6.97 min (30% of total time) corresponded to the time available, which is far from the recommendations on school-age physical activity.

A Novel Prognostics Approach Using Shifting Kernel Particle Filter of Li-Ion Batteries Under State Changes

Lithium-ion (Li-ion) batteries are used in various applications as the rechargeable power sources. The batteries undergo capacity fade during the repeated charge–discharge cycles, which eventually leads to the end of life (EOL). For the purpose of timely replacement before reaching the EOL, reliable prediction of the remaining useful life (RUL) during the cycles is of great importance. However, there may exist unhealthy batteries exhibiting the change of state at some cycles from those of normal degradation, which leads to their EOL sooner than expected. In this article, we propose a novel prognostic method using the particle filter (PF) that is capable of detecting the point of state change and adapting its algorithm to the new battery degradation pattern. The performance of the proposed method is demonstrated by the case study of Li-ion battery degradation data, comparing with the original PF algorithm. As a result, the proposed method shows better performance in terms of anomaly detection of degradation and adaptability to the new degradation process, which leads to more accurate and reliable RUL prediction.
