Níveis de potência muscular em atletas de futebol e futsal em diferentes categorias e posições Levels of muscle power in soccer and futsal athletes of different categories and positions

This study aimed to identify the height obtained in the power of lower limb in soccer and futsal players, comparing the counter movement jump (CMJ) among the modalities, game positions and categories. Took part of the study 61 soccer athletes from under-17, under-20 and professional categories and 28 futsal athletes from the under-20 and professional categories. It was used a piezoelectric force platform Quattro jump. It was used descriptive statistics, student “t” test and analysis of variance set at p < . 05. No significant difference was reported in the CMJ between the soccer and futsal athletes (p = .85). Among the positions adopted by soccer players it was found significant difference (p = .02) only between those in defensive positions and those in the midfield. In the futsal athletes it was not reported significant difference between positions (p = .69). Compared to other categories no significant differences were found, neither in soccer (p = .12) nor in futsal (p = .47). It can be concluded that the soccer and futsal athletes seems to present similar level of muscle power. Those in defensive positions presented higher levels of power when compared to those in the midfield, but in futsal the athletes presented similar power levels. Independent of the category, both soccer and futsal athletes presented similar level of muscle power.
Surface Plasmon Resonance (SPR) Determination of Adenosine Triphosphate (ATP) Using Silver (I) induced Configuration Changes of a Single Stranded DNA Probe with Cytosine (C)

Abstract ATP is related to the occurrence of many diseases, its facile, sensitive and accurate determination in real samples is needed for disease screening and treatment. Although some methods realized the sensitive detection of ATP using the signal amplification of cyclic reactions or nanoparticles, complex experimental processes limit their applications. In this paper, we report a simple surface plasmon resonance (SPR) method based on a single stranded DNA probe. The probe has dual recognition sites of ATP and Ag+; namely the ATP aptamer located in the middle of the probe and five cytosine (C) at both ends of the probe. In the absence of ATP, the probe transforms into a rigid hairpin structure by forming C-Ag+-C structures and produces a large SPR signal. However, once the probe interacts with ATP, three-dimensional structures are formed, and then the Ag+-induced probe configuration change is smaller, resulting in an small SPR signal. The signal difference before and after the probe interacts with ATP is proportional to the analyte concentration. The probe configuration change is in the optimum area for SPR detection, ensuring the sensitive ATP determination. The signal difference has a linear response with the logarithm of ATP concentration from 0.05 to 500 nM with a detection limit of 15 pM. Moreover, the strategy was demonstrated to determine ATP in serum samples with satisfactory recoveries. The results show that this simple and sensitive method has potential applications for clinical ATP determination.
Work Effort in the UK: Trends and Explanations

IZA DP No. 15329 MAY 2022 Work Effort in the UK: Trends and Explanations This paper links detailed 24-hour diary surveys in the United Kingdom (UK) over the last four decades to provide evidence on the increase in work effort in three specific dimensions: timing, nature, and composition. We rule out possible explanations behind these trends, finding that the decrease in the frequency of on-the-job leisure is more pronounced for workers in routine task-intensive occupations. Alternative supplyand demand-side explanations, such as changes in the relative preference for leisure, or the increase in offshoring, or competition for jobs, cannot explain our results. Our findings posit the amount and the frequency of on-the-job leisure as a measure of work effort, and the routine-biased technological change experienced during this period lies at the root of the increase in work effort in the UK.

Pool Compression for Undirected Graphs

We present a new graph compression scheme that intrinsically exploits the similarity and locality of references in a graph by first ordering the nodes and then merging the contiguous adjacency lists of the graph into blocks to create a pool of nodes. The nodes in the adjacency lists of the graph are encoded by their position in the pool. This simple yet powerful scheme achieves compression ratios better than the previous methods for many datasets tested in this paper and, on average, surpasses all the previous methods. The scheme also provides an easy and efficient access to neighbor queries, e.g., finding the neighbors of a node, and reachability queries, e.g., finding if node <inline-formula> <tex-math notation="LaTeX">$u$ </tex-math></inline-formula> is reachable from node <inline-formula> <tex-math notation="LaTeX">$v$ </tex-math></inline-formula>. We test our scheme on publicly available graphs of different sizes and show a significant improvement in the compression ratio and query access time compared to the previous approaches.
Ovulation Enhances Intraperitoneal and Ovarian Seedings of High-Grade Serous Carcinoma Cells Originating from the Fallopian Tube: Confirmation in a Bursa-Free Mouse Xenograft Model

Background: Recently, new paradigms for the etiology and origin of ovarian high-grade serous carcinoma (HGSC) have emerged. The carcinogens released during ovulation transform fallopian tube epithelial cells, exfoliating and metastasizing to the peritoneal organs, including the ovaries. Solid in vivo evidence of the paradigms in a mouse model is urgently needed but is hampered by the differing tubo-ovarian structures. In mice, there is a bursa structure surrounding the distal oviduct and ovary. This, on one hand, prevents the direct influence of ovulatory follicular fluid (FF) on the exfoliated tumor cells. On the other hand, it hinders the seeding of exfoliated tumor cells into the ovary. Methods: In this study, we created a bursa-free mouse xenograft model to examine the effect of superovulation on peritoneal and ovarian metastases of transformed human tubal epithelial cells after intraperitoneal injection in NSG mice. Results: The bursa-free mouse model showed a better effect of ovulation on peritoneal metastasis. In this model, superovulation increased the number of transformed human tubal epithelial cell seedlings after intraperitoneal injection. Compared to the bursa-intact state, bursa-free ovaries were more vulnerable to external tumor seeding in either normal ovulation or superovulation state. Conclusions: This study provides the first in vivo evidence that intraperitoneal spreading of tubal HGSC cells is enhanced by ovulation. This study also demonstrated a mouse model for studying ovary-peritoneum interaction in cancer development.
Hotel offer adjustments for senior citizen guests: perception of Swiss hoteliers

This paper presents the results of a questionnaire-based exploratory survey among hoteliers in Switzerland, measuring their perception of the senior clientele. These hoteliers were also asked about the specific arrangements they have made in the past for the senior customers, as well as the investments they have undertaken. The main finding is that, even though the senior segment is recognised by most hoteliers as being potentially profitable, a less than flattering image of this customer category seems to have dissuaded a great number of Swiss hoteliers from concentrating a lot of effort and resources on adapting their products and services to this customer segment. This bad image (serious physical handicaps, problems in cohabitation with other clients) deserves to be corrected. Besides, the wish of senior tourists for a personalised product and service should be taken into account by Swiss hoteliers in their future investments and offers aimed at the senior guests.
Deep learning with RGB and thermal images onboard a drone for monitoring operations

This article describes the artificial intelligence (AI) component of a drone for monitoring and patrolling tasks associated with disaster relief missions in specific restricted disaster scenarios, as specified by the Advanced Robotics Foundation in Japan. The AI component uses deep learning models for environment recognition and object detection. For environment recognition, we use semantic segmentation, or pixel‐wise labeling, based on RGB images. Object detection is key for detecting and locating people in need. Since people are relatively small objects from the drone perspective, we use both RGB and thermal images. To train our models, we created a novel multispectral and publicly available data set of people. We used a geo‐location method to locate people on the ground. The semantic segmentation models were extensively tested using different feature extractors. We created two dedicated data sets, which we have made publicly available. Compared with the baseline model, the best‐performing model could increase the mean intersection over union (IoU) by 1.3%. Furthermore, we compared two types of person detection models. The first one is an ensemble model that combines RGB and thermal information via “late fusion”; the second one is a 4‐channel model that combines these two types of information in an “early fusion” manner. The results suggest that the 4‐channel model had a 40.6% increase of average precision for stricter IoU values (0.75) compared with the ensemble model and a 5.8% increase in the average precision compared with the thermal model. All models were deployed and tested on the NVIDIA AGX Xavier platform. To the best of our knowledge, this study was the first to use both RGB and thermal data from the perspective of a drone for monitoring tasks.
STRATEGI NAFKAH (LIVELIHOOD) MASYARAKAT PESISIR BERBASIS MODAL SOSIAL

growth) dan mengandalkan mekanisme pasar (market mechanism) untuk menghasilkan pertambahan nilai (surplus value). Proses akumulasi surplus dipengaruhi oleh proses globalisasi, masuknya industri pangan transnasional ke ekonomi nasional, dan oleh penekanan pada ekspor pertanian (dalam arti luas) sebagai motor akumulasi perubahan. Seiring dengan hal tersebut, pemerintah mulai serius melirik pembangunan masyarakat pada wilayah pesisir yang sebelumnya kurang tersentuh. Untuk “mengenjot” pertumbuhan ekonomi dari sektor yang “kaya raya” ini dikembangkanlah modernisasi teknologi penangkapan berlabel “revolusi biru”. Namun sejak program itu bergulir, kehidupan nelayan justru mengalami polarisasi. Bagi nelayan yang memiliki modal cukup, kehadiran teknologi perikanan menjadi semacam berkah tersendiri. Namun bagi nelayan yang miskin dan tidak mampu membeli teknologi, kehadiran teknologi justru dirasakan seperti bencana. Sebab selama ini mereka hanya mengandalkan modal sosial sebagai basis nafkah agar tetap eksis sebagai sebuah komunitas. Tulisan ini merupakan hasil studi pustaka yang dipadu hasil observasi penulis terhadap masyarakat pesisir (nelayan) selama ini, dengan menggunakan analisa deskriptif yang didasarkan pada fakta mengenai strategi nafkah rumah tangga nelayan di Lamongan Jawa Timur. Hasil studi menunjukkan bahwa strategi nafkah berbasis modal sosial bagi nelayan miskn menjadi sumberdaya nyata dalam pengembangan beragam pilihan strategi nafkah. Strategi nafkah dilakukan cenderung tersebar, mengikuti semua peluang mata pencaharian, atau pola nafkah yang berserak. Ini terjadi karena sifat modal alami utamanya adalah laut (open access), yang diperburuk oleh sangat terbtasannya akses bagi mereka terhadap teknologi penangkapan modern sehingga ketidakpastian penghasilan sangat tinggi. Kemiskinan sangat menuntut ketahanan rumahtangga nelayan untuk bertahan hidup, melalui pemanfaatan dan oftimalisasi peran modal sosial sebagai sumberdaya terakhir ketika rumahtangga nelayan kehabisan daya dan amunisi untuk bertahan hidup. Kekuatan modal sosial pada rumahtangga nelayan berupa bounding social capital rumahtangga dan kekerabatan sebagai modal sosial utama. Kemudian bridging social capital merujuk pada pemeliharaan hubungan nelayan dengan juragan dan bank titil/rentenir sebagai asuransi sosial, sementara linking social capital dilakukan kepada penyalur TKI sebagai pemberi modal kerja dan penjamin kepastian kerja. Modal sosial lain yang tak kalah pentingnya bagi mereka perankan adalah jaringan sosial, kepercayaan dan nilai/norma serta adanya resiprositas yang berlaku pada komunitas mereka. Key word : Transformasi, kemiskinan, strategi nafkah (livelihood), dan modal sosial

Existing techniques for this NP-hard problem strive to quickly find a seed set with a <italic>high</italic>, but not necessarily the highest centrality. We propose <monospace>PRESTO</monospace>, a new solution that can efficiently provide both approximate and exact answers to the group closeness maximization problem. <monospace>PRESTO</monospace> continuously calculates the centrality of different seed sets until a time limit is reached or it identifies a seed set with the highest possible centrality. It prioritizes seed sets to quickly find ones that are highly central and thus can be used as accurate approximate answers to the problem. Furthermore, <monospace>PRESTO</monospace> can proactively discard large groups of seed sets that cannot have the highest centrality, thereby drastically speeding up the discovery of approximate and exact answers. In our evaluations, compared to other state-of-the-art solutions, <monospace>PRESTO</monospace> finds seed sets that have up to 39% higher centrality.
Trends of Tropical Cyclone Translation Speed over the Western North Pacific during 1980−2018

Tropical cyclone (TC) translation speed often affects the time of strong wind attacks and precipitation accumulation in the areas that TCs pass through. Therefore, the trend of TC translation speed has important implications for TC-related risks in the current and future climate. In this paper, the trends of TC translation speed over the Western North Pacific (WNP) from 1980 to 2018 are analyzed, and TC lifetime maximum intensity (LMI) is proposed as a factor related to the interdecadal change of translation speed. During the periods with accurate data, 1980–1997 shows a decreasing trend in TC translation speed while an increasing trend was found in 1998–2018. The main lifetime period contributing to a TC translation speed change is before the occurrence of the LMI. The change in the trend is related to both the TC’s characteristics itself and the environmental factors. For the period 1998–2018, an increasing trend of TC intensity has a significant influence on the trend of translation speed. For the environmental factors, a trend of east wind enhancement at and above 500 hPa as the steering flow is found mostly correlated in the active TC region of the WNP with westward translation before reaching LMI, accompanied by a weakening trend of 200–850 hPa vertical wind shear, and an increasing trend of potential intensity.
How cloud infrastructure can be built with low resource across multiple Cloud Platforms

At present, Cloud Computing (CC) has been leading platform over the Internet. Virtualization is one significant part for the growth of cloud computing and to manage infrastructure across multi-cloud vendors. In this research, we study about Docker container and address to achieve high availability by building virtualizaation in cloud infrastructure deployment in multi-cloud framework and to over come the networking issues face by Docker. We focused to manage cloud infrastructure management with less resources and improve the networking server by creating private DNS server which will connect to all the container deploy in different cloud platform. The novel approach we brought, in this research is improvement of the cloud infrastructure management in multi cloud platform. This study is helpful to solve the networking issues in Docker framework. We used private DNS, as a networking server each cloud platform. This it result to improve connectivity among the containers deploy in different cloud vendor. We deploy multiple number of containers which is then connecting to the DNS server. To check the test performance we used YCSB tool. With the implementation of our proposed architecture, results to better performance of the MongoDB. We also test our proposed infrastructure by implementing in three different cloud vendor which prove the best performance of our infrastructure. We achieved, high availability over MongoDB clustered infrastructure when implement and compare among three different cloud platform.
Evolution of Union Wages and Determinants

IZA DP No. 15333 MAY 2022 Evolution of Union Wages and Determinants Labor unions, chiefly through collective organizing and bargaining, almost universally increase the wages of their members, even after controlling for individual, job, firm, and other characteristics that affect pay (Fang and Verma 2002). This earnings advantage of union workers is known as the union wage premium. The premium differs by country, industry, worker, and the estimated wage premium varies by study methodology, among other factors. This chapter explains the premium’s determinants and charts how they have changed over time, leading to a typically reduced wage effect in recent years relative to decades past. Such changes include globalization, technological change and a rise in the skill premium, a shift toward the service industry, less favorable labor law, and possibly increased opposition toward unions. Methodological challenges and empirical techniques are reviewed, and premium estimates by country/region are presented. An average union wage premium of 0-20% is found based on recent research, with considerable variation depending on the methodology and country under study. The literature focuses on several developed countries, and is limited in a number of developing nations, with data availability being the primary reason. Results from the developing world exhibit more variation, but often fall in line with those from developed countries such as the United States. JEL Classification: J31, J33, J51
Psychosocial factors of risk and protection associated with juvenile cyberbullying victimization: results from an international multi-city study (International Self-Report Delinquency Study 3, ISRD3)

The growing use of technologies makes it easy for children and young people to access or produce offensive content, giving rise to a new form of bullying: cyberbullying. Several individual and environmental protection and risk factors are involved with cyberbullying victimization. The present study aims to provide some empirical data that can help in understanding cyberbullying and in the formulation of programmes for its prevention. For this purpose, the data of the ISRD3 (International Self-Report Delinquency Study 3) survey were used. Data show that, for strategies of prevention and intervention to be effective, they should consider multiple systems, such as the family, peers, school and community.
Solid-State Lithium-Ion Batteries as a Method for Doping Halide Perovskites with an In Situ Optical Readout of Dopant Concentration

Controlled doping of halide perovskites is a longstanding challenge for efficient optoelectronic applications. Here, a solid-state lithium-ion battery (LIB) inspired device is used as a method of extrinsically doping a halide perovskite in a controlled and measurable fashion. The Burstein–Moss band gap shift induced by the electronic doping is measured using in situ optical spectroscopy to monitor the fraction of injected charges that successfully n-type dope the perovskite. By comparing the optical and electrochemical readouts of the charge density, we demonstrate a 96% doping efficiency during the insertion process. Subsequent charge removal steps demonstrate only a partial “undoping” of the perovskite, providing insights into the capacity degradation pathways in perovskite LIB electrodes.
Cointegration between Macroeconomic Variables and Stock Market Returns in Nepal

This paper examines the long-run relationship between selected macroeconomic variables and the stock market returns in Nepal over 1995-2020 periods. Based on the ARDL bounds testing approach, the study reveals significant long-run positive impact of real GDP growth, and negative impact of exchange rate and inflation on stock market returns in Nepal. The result of error correction representation shows that any short-run disequilibrium among the variables tends to return to their long-run equilibrium with speed of adjustment of 47.57 percent in a year. The study results imply that policy makers should come up with policies to accelerate the pace of economic growth and should initiate export stimulating policies to ensure the positive impact on stock market. Finally, the study results also suggest that controlled and stabilised interest rate environment enhances depth and breadth of stock market trading by attracting significant number of prospective investors demanding more investments in stock market of Nepal.
Parents' Perception of the Use of Digital Book Reading App in Improving English Skills for Early Childhood

Literature studies have shown benefits of using technology and multimedia to improve children's engagement and interest in learning. However, the use of technology for children is still receiving mixed views from parents. Digital books are an alternative innovation that can be used by parents to improve their children's English skills in a fun way. Incorporated features in digital books such as voiceover, interactivity, and background music can help children improve their vocabulary and comprehension. Digital books are also believed to be able to facilitate children's needs for access to a variety of books that can be read anywhere and anytime. This study focuses on parents’ perception regarding the use of digital book reading applications in improving children’s English skills. This study used a descriptive qualitative method with five parents of children aged 4 - 8 years old who have used a digital book reading application named Vocacio for 14 days. The data in this study is obtained by doing an in-depth interview with the parents. The result of the study shows that parents have mixed perceptions regarding the use of digital book reading applications in improving children’s reading interest, reading comprehension, reading fluency, and English vocabulary.
