The method in this study was a descriptive method with a quantitative approach with the aim to determine the effect of the variables studied. The population in this study were all Civil Servants covered by Disperkimtan Sulsel, amounting to 135 people. While the sample used in this study amounted to 134 people. Data collection techniques using survey methods through observation, questionnaires, and literature study. Data analysis was performed using SPSS ( Statistical Package for the Social Science) version 25. The results of this study indicated that direct incentives and work environment have a positive and significant effect on job satisfaction and employee performance in Disperkimtan South Sulawesi. There was no positive and significant effect between incentives on performance through job satisfaction as an intervening variable. While job satisfaction as an intervening variable that mediates between work environment and performance has no positive and significant effect. In this case, job satisfaction weakened the influence of the work environment on the performance of civil servants.
Linear Viscoelastic and Dielectric Properties of Strongly Hydrogen-Bonded Polymers near the Sol–Gel Transition

Linear viscoelastic and dielectric measurements were conducted for a model associating polymer system, n-butyl acrylate (PnBA)-based copolymers containing 2-ureido-4[1H]-pyrimidinone (UPy) groups as stickers. The number of stickers per chain was varied from less than one to more than two, which covered a sol-to-gel transition region. Fitting the linear viscoelasticity (LVE) to an analytical model developed in our previous study, we found necessity of distinguishing the intra- and interchain association in the model, with only the latter contributing to the gel formation. For the PnBA-Upy sample slightly above the gel point, the relaxation processes due to the Rouse motion and the sticker dissociation were commonly detected in the same range of T covering from 20 to 60 °C. This feature enabled us to make the time–temperature superposition separately for respective relaxation processes, and two sets of shift factors, reflecting the temperature dependence of the Rouse time τ0 and dissociation time τs, were o.
Characterization of TiB2 reinforced aluminum matrix composite synthesized by in situ stir casting method

In this study, TiB2 reinforced Al-matrix composite was fabricated by in situ stir casting route, and the effect of processing parameters was investigated. X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) equipped with energy-dispersive X-ray spectroscopy (EDX) were used to study the composition and microstructure of the samples. Finally, to investigate the tribological and electrochemical behavior of the samples, wear tests (pin-on-disk) and potentiodynamic polarization tests (PDP) were used, respectively. Results showed that by increasing stirring time, both tribological and mechanical behavior of the samples improved. Also, it was found that by increasing the stirring speed of the melt to 180 rpm, the mechanical and tribological behavior of the samples improved, and by further increasing the stirring speed to 300 rpm, they were decreased. Consequently, samples containing lower than 7 wt. % TiB2 showed better metallurgical properties, due to lack of agglomeration.

Aplicação de Filtro Harmônico Ativo em Plataforma Laboratorial Destinada a Estudos de Qualidade da Energia Elétrica

The concern regarding power quality has attracted the attention of several segments of the electricity sector, with special emphasis on harmonic distortions due to the exponential increase of nonlinear devices at all levels of electric systems. However, since the presence of harmonics is a potential cause of problems to the equipment of the electrical system, its mitigation is essential for the proper functioning of its installations. Therefore, among the existing mitigation strategies, the use of passive filters is the most widespread, although some factors have led to the development of harmonic compensation technologies via active filters practically and commercially. Therefore, due to the relevance of harmonic mitigation in industrial environments, this work aims at demonstrating harmonic distortion mitigations, didactically, by connecting a prototype of an active filter to a laboratory structure representative of an industrial electric system developed to carry out studies and research in power quality. Resumo: A preocupação com a qualidade da energia tem atraído a atenção dos diversos segmentos do setor elétrico, com especial ênfase às distorções harmônicas, dado o exponencial crescimento de dispositivos não lineares nos diversos níveis dos sistemas elétricos. Porém, como a presença de harmônicos é um potencial causador de problemas aos equipamentos do sistema elétrico, sua mitigação é essencial para o adequado funcionamento de suas instalações. Para tanto, entre as estratégias de mitigação existentes, a utilização de filtros passivos é a mais largamente difundida, embora alguns fatores têm levado ao desenvolvimento das tecnologias de compensação harmônica via filtros ativos, de forma prática e comercial. Assim sendo, devido à relevância da mitigação harmônica em ambientes industriais, este trabalho objetiva demonstrar a mitigação de distorções harmônica, de forma didática, pela conexão de um protótipo de filtro ativo a uma estrutura laboratorial representativa de um sistema elétrico industrial desenvolvida para realização de estudos e pesquisas em qualidade da energia.
Ambiente obesogênico universitário: achados de uma cidade brasileira

Introduction: The environment may influence negatively the quality of individuals’ food consumption, constituting the so-called obesogenic environments. The aim of the study was to evaluate the types of food retailers and the availability of foods according to the degree of industrial processing, inside and around the Federal University of Juiz de Fora, at Juiz de Fora, Brazil. Methods: This exploratory study evaluated all food retailers located within a buffer with a 500 meters radius. Data of latitude and longitude of the establishments and information about the sold foods were collected. The establishments were grouped according to their characteristics and the processing level of the most part of the marketed foods. Fisher's exact test were used to test the association between the type of Bianca Elidia Sodré, Maria Alvim Leite, Mirella Lima Binoti | Ambiente obesogênico universitário: achados de uma cidade brasileira de grande porte R.

Conclusion: It is observed that the food environment in which students and university employees are exposed can be characterized with a low nutritional quality.
A Novel Layer Sharing-based Incremental Learning via Bayesian Optimization

Incremental learning means the methodology that continuously uses sequential input data to extend the existing network’s knowledge. The layer sharing algorithm is one of the representative methods which leverages general knowledge by sharing some initial layers of the existing network. In this algorithm, estimating how much initial convolutional layers of the existing network can be shared as the fixed feature extractors for incremental learning should be solved. However, the existing algorithm selects the sharing configurations through not a proper optimization strategy but a brute force manner. Accordingly, it has to search for all possible sharing layer cases, leading to high computational complexity. To solve this problem, we firstly define this problem as a discrete combinatorial optimization problem. However, this problem is a non-convex and non-differential optimization problem which can not be solved using the gradient descent algorithm or other convex optimization methods, even though these are the powerful optimization techniques. Thus, we propose a novel efficient incremental learning algorithm based on Bayesian optimization, which guarantees the global convergence in a non-convex and non-differential optimization problem. And the proposed algorithm can adaptively find the optimal number of sharing layers via adjusting the threshold accuracy parameter in the proposed loss function. The proposed method produces the global optimal sharing layer number in only 6 iterations without searching for all possible layer cases in experimental results. Hence, the proposed method can find the global optimal sharing layer and achieve both high combined accuracy and low computational complexity.
Sarcasm Detection Using Multi-Channel Attention Based BLSTM On News Headline

Sarcasm is often used to express a negative opinion using positive or intensified positive words in social media. This intentional ambiguity makes sarcasm detection, an important task of sentiment analysis. Detecting a sarcastic tone in natural language hinders the performance of sentiment analysis tasks. The majority of the studies on automatic sarcasm detection emphasize on the use of lexical, syntactic, or pragmatic features that are often unequivocally expressed through figurative literary devices such as words, emoticons, and exclamation marks. In this paper, we introduce a multi-channel attention-based bidirectional long-short memory (MCAB-BLSTM) network to detect sarcastic headline on the news. Multi-channel attention-based bidirectional long-short memory (MCAB-BLSTM) proposed model was evaluated on the news headline dataset, and the results-compared to the CNN-LSTM and Hybrid Neural Network were excellent.
Impacto da Penetração em Larga Escala de Microgeradores na Proteção de Sobrecorrente em Sistemas de Distribuição

With the increasing in distributed generation, the protection of distribution systems, previously planned for unidirectional power flow, need more attention. This paper proposes the analysis of the maximum number of distributed microgenerators connected at the low voltage network that does not influence the coordination of the medium voltage protection system. In this approach, the photovoltaic panels (inverter-based generators) and the wind generators (asynchronous generators), will be considered separately. The maximum number of generators connected was estimated considering the short-circuit model provided by IEC 60909 standard and compared with simulations performed by DIgSILENT PowerFactory software. Finally, the estimate proved to be effective in predicting the maximum power injection of distributed microgeneration, maintaining the regular operation of the protection system analyzed. The maximum number of solar microgenerators connected in parallel was over five times higher than the number of wind microgenerators. This indicated that the photovoltaic panels only will impact the protection system when applied in large scale, like an equivalent among several consumers. Resumo: Com o aumento da geração distribúıda, a proteção dos sistemas de distribuição, previamente planejados para fluxo de potência unidirecional, precisam de maior atenção. Este artigo propõe a análise do número máximo de microgeradores distribúıdos conectados em baixa tensão que não influenciam a coordenação do sistema de proteção em média tensão. Para isso, serão considerados separadamente geradores fotovoltaicos (geradores baseados em inversores) e eólicos (geradores asśıncronos). O número máximo de geradores distribúıdos foi estimado considerando o modelo de curto-circuito apresentado pela norma IEC 60909 e posteriormente comparados com simulações realizadas no software DIgSILENT PowerFactory. Por fim, a estimativa realizada provou ser eficaz na predição da máxima injeção de potência dos microgeradores distribúıdos, mantendo a operação adequada do sistema de proteção em média tensão. Dessa forma, observou-se que o número máximo de microgeradores solares em paralelo foi mais de cinco vezes superior ao de microgeradores eólicos, indicando que os painéis fotovoltaicos somente impactarão o sistema de proteção quando aplicados em larga escala.
Leaky-Wave Antennas for 5G/B5G Mobile Communication Systems: A Survey

Since leaky-wave antennas (LWAs) have the advantages of high directivity, low loss and structural simplicity, LWAs are very suitable for designing millimeter-wave (mmW) antennas. The purpose of this paper is to review the latest research progress of LWAs for 5G/ B5G mobile communication systems. Firstly, the conventional classification and design methods of LWAs are introduced and the effects of the phase constant and attenuation con‐ stant on the radiation characteristics are discussed. Then two types of new LWAs for 5G/ B5G mobile communication systems including broadband fixed-beam LWAs and frequencyfixed beam-scanning LWAs are summarized. Finally, the challenges and future research di‐ rections of LWAs for 5G/B5G mobile communication systems are presented.
Moiré Chiral Metamaterials

Plasmonic chiral metamaterials are promising for applications in chiral sensors and photonic devices due to their strong optical chirality and light–matter interactions at the subwavelength scale. However, most of current plasmonic chiral metamaterials rely on local structural chirality or site‐specific symmetry breaking, which has limited their optical activity, tunability, and scalable fabrication for practical applications. Here, this paper reports a new type of chiral metamaterials consisted of two layers of identical achiral Au nanohole arrays stacked into moiré patterns. The chiroptical responses of the moiré chiral metamaterials can be precisely tuned by the in‐plane rotation between the two layers of nanohole arrays. Furthermore, the moiré chiral metamaterials are applied to achieve label‐free enantiodiscrimination of biomolecules and drug molecules at the picogram level. With their ultrathin thickness (≈70 nm, which is only ≈1/10 of the operation wavelength), strong chirality, and high tunability, the moiré chiral metamaterials will advance a variety of photonic and optoelectronic applications.
A Time to Plot, A Time to Reap: Coups, Regime Changes, and Inequality

ABSTRACT A vast economic literature examines the welfare gains and distributional consequences of economic reforms, while much less is generally known on the relationship of inequality and forced regime changes. Some studies analyze how economic inequality impacts the likelihood of coups, but the distributional outcomes of such events have been largely ignored to date. Employing novel data, we find that successful coups have a significant positive impact on the consumption shares of the lowest quintile and a strong negative impact on the highest quintile, as compared to the inexistent redistribution that results from failed coups. In addition, the redistributive effect is stronger for military coups, as compared to civilian coups, and effects seem to be substantially driven by coups against democratic regimes. Despite their negative impact on overall growth and per capita income, our results show that forced regime changes, as compared to non-successful attempts, reduce inequality at a short notice. This may partially explain their continued popularity in highly unequal developing countries.
