Physiological and physical effects associated with task constraints, pitch size, and floater player participation in U-12 1 × 1 soccer small-sided games

Purpose. The study aim was to analyse 1 × 1 small-sided games (SSGs) with and without floating players, in different pitch sizes. Methods. Ten U-12 soccer players were divided into 2 groups. Group 1 ( n = 4) performed 1 × 1 SSG and group 2 ( n = 6) performed 1 × 1 + 1 SSG. Field sizes of 5 × 10 m (SSG1), 10 × 15 m (SSG2), and 15 × 20 m (SSG3) were used, all with small goals. The studied variables were heart rate (HR), total distance, explosive distance (> 12 km/h), accelerations, decelerations, maximum sprint, player load (PL) intensity and volume. The data were collected through WIMU PROTM and analysed with IbM SPSS Statistics. Descriptive analyses and comparisons between the effects of internal and external PL and SSG were performed with the Mann-Whitney U test. Results. Increasing the pitch size in 1 × 1 and 1 × 1 + 1 SSGs led to raised total distance, maximum sprint, and PL. In 1 × 1 and 1 × 1 + 1 SSGs, the time practice was predominantly associated with HR max intervals above 90%. Statistically sig ni ficant differences were observed between 1 × 1 and 1 × 1 + 1 SSGs in explosive distance (SSG2: 46.40 ± 5.07 / 28.99 ± 4.93, p = 0.02, ES( r ) = 0.82), PL intensity (SSG2: 2.03 ± 0.11 / 1.78 ± 0.12, p = 0.02, ES( r ) = 0.82), HR max (SSG1: 189.50 ± 1.91 / 199.50 ± 2.38, p = 0.01, ES( r ) = 0.82), and HR mean (SSG1: 174.50 ± 3.31 / 181.75 ± 2.21, p = 0.01, ES( r ) = 0.82). Floating players’ physical and physiological demands were lower compared with the other athletes. Conclusions. The pitch size influences the physiological and physical response of young soccer players in SSGs. The demand of 1 × 1 SSG is higher compared with 1 × 1 + 1. Floating player participation could result in a fruitful strategy to adjust the training intensity of specific soccer players.
Adaptive Partial Offloading and Resource Harmonization in Wireless Edge Computing-Assisted IoE Networks

Wireless backhaul is considered a portable and cost-effective solution for deploying small cell-assisted communications in mobile Internet of Everything (IoE) networks. In this system, the wireless backhaul between a central gNodeB (gNB) and small cell base stations (SBSs) shares the frequency spectrum with the wireless fronthaul between the SBSs and user devices. In these circumstances, efficient edge computing deployment requires joint optimization of wireless resource harmonization and partial offloading scheduling to accommodate heterogeneous IoE services. Therefore, in this study, we formulate the system model as a Markov decision process (MDP) to minimize the weighted sum of computation overheads in terms of the latency and energy costs of all user equipment (UE) where network dynamics are considered in the system state. Consequently, an actor–critic reinforcement learning algorithm, i.e., a deep deterministic policy gradient (DDPG)-based algorithm with replay memory technique, is proposed to realize an adaptive offloading decision scheme and optimal wireless resource harmonization between the backhaul and fronthaul. Extensive simulation results reveal that the proposed algorithm reliably converges and provides approximately 70%, 55%, 36%, and 11% lower total computation overhead than UE execution, random, MEC execution, and DQN-based schemes, respectively.
Coffee by-products as the source of antioxidants: a systematic review

Background: Solid waste from coffee depulping process threatens the organism in environment as it produces organic pollutants. Evidence suggested that coffee by-product could valorize owing to its potential as antioxidant sources. The aim of this systematic review was to evaluate antioxidant activity of coffee by-products obtained from different coffee variants (arabica and robusta) and processing methods. Methods: The systematic review was conducted as of May 29, 2021 for records published within the last ten years (2011–2021) using seven databases: Embase, Medline, BMJ, Web of Science, Science Direct, Cochrane, and PubMed. Data on type of specimen, processing methods, and antioxidant activities were collected based on PRISMA guidelines. Results: Our data suggested that aqueous extract was found to be the most common processing method used to obtain the antioxidant from various coffee by-products, followed by methanol and ethanol extract. A variety of antioxidant properties ranging from strong to low activity was found depending on the variety, type of coffee by-products (cascara, pulp, husk, silverskin, and parchment), and processing technique. Fermentation employing proper bacteria was found effective in improving the yield of bioactive compounds resulting in higher antioxidant capacity. Applications in feedstuffs, foods, beverages, and topical formulation are among the potential utilization of coffee by-products. Conclusion: Coffee by-products contain bioactive compounds possessing antioxidant properties which could be used as additives in foods, beverages, and cosmetics. In particular, their benefits in skin care products require further investigation.
RPS9 promotes the progression of NSCLC via activation Stat3 and Erk signaling pathways

Background: Non-small cell lung cancer (NSCLC) accounts for the largest pathological type of lung cancers, and it is characterized by high incidence and poor prognosis. However, the molecular mechanisms involved in development and progression of NSCLC are not well elucidated. In this study, we aimed to explore the role and regulatory mechanism of RPS9 in NSCLC. Materials and methods: The RPS9 expression in NSCLC tissues and cell lines was assessed by qRT-PCR and western blot. Knockdown of RPS9 induced by RNA interference (RNAi) method in PC9, A549 and H1299 cells. Overexpression of RPS9 induced by transient transfection in H292 cells. Cell proliferation, colony formation, metastasis and apoptosis abilities were determined by CCK-8 assay, colony formation assay, transwell assay and flow cytometry, respectively. The host signaling pathways affected by RPS9 were screened by antibody library and proved by western blot. Results: RPS9 was significantly upregulated in NSCLC tissues and cell lines. Overexpression of RPS9 predicted poor prognosis of NSCLC patients. Knockdown of RPS9 obviously repressed cell proliferation, metastasis, and induced apoptosis. Mechanistically, suppression of RPS9 inhibited the expression level of phosphorylation of Stat3 and Erk. Conclusion: Our study clarified that knockdown of RPS9 inhibits the progression of NSCLC via inactivation Stat3 and Erk signaling pathways.
L2 French learning by Eritrean refugee speakers of Tigrinya

Abstract This study reports data on 47 Tigrinya speaking Eritrean refugees learning French. L2 French proficiency is assessed through the placement test Ev@lang, a standardized grammar test, and fine corpus analyses. Analysis of individual factors shows that, whereas school education, number of years in Switzerland, and French classes attended play no role in proficiency, age penalizes learning and, critically, multilingualism facilitates it. Corpus analyses replicate difficulties commonly reported in the literature with root infinitives, determiner omission and gender errors. Productions also depart from previous reports as we observed a low rate of subject drop, a high rate of gender errors involving animate nouns, and the overuse of the feminine, in line with Tigrinya grammar. Finally, our data provide preliminary evidence of the validity of Ev@lang in assessing French proficiency in refugees, an issue which is becoming critical with the increased role of language skills in European asylum policies.
Real-Time Analysis of Hand Gesture Recognition with Temporal Convolutional Networks

In recent years, the successful application of Deep Learning methods to classification problems has had a huge impact in many domains. (1) Background: In biomedical engineering, the problem of gesture recognition based on electromyography is often addressed as an image classification problem using Convolutional Neural Networks. Recently, a specific class of these models called Temporal Convolutional Networks (TCNs) has been successfully applied to this task. (2) Methods: In this paper, we approach electromyography-based hand gesture recognition as a sequence classification problem using TCNs. Specifically, we investigate the real-time behavior of our previous TCN model by performing a simulation experiment on a recorded sEMG dataset. (3) Results: The proposed network trained with data augmentation yields a small improvement in accuracy compared to our existing model. However, the classification accuracy is decreased in the real-time evaluation, showing that the proposed TCN architecture is not suitable for such applications. (4) Conclusions: The real-time analysis helps in understanding the limitations of the model and exploring new ways to improve its performance.
A Person-Centered Approach to Sustaining a Lean Environment - Job Design for Self-Efficacy

Abstract : Toyota credits its team members for the success and sustenance of the Toyota Production System. The power of a highly skilled and motivated workforce is a significant competitive advantage for any company, in any industry. Toyota's team members collectively make hundreds of thousands of improvements to their work every year, reducing costs, reducing cycle times, and improving working conditions. Drawing on old and new research, this paper poses a theoretical explanation for why employees get involved and stay involved in transformational activities in organizations. It will explore relationships between corporate belief systems, job and employee satisfaction, and individual self-efficacy and then offer a way for companies to apply all of these theoretical ideas through two practical tools.
Uptake and translocation of foliar applied phosphite and its effect on growth and development in cool season turfgrass

Abstract Phosphate (PO4 3-, Pi) is the sole phosphorus (P) containing compound utilized for plant growth, leading to the widespread use of Pi containing fertilizers. An alternative form of P, phosphite (PO3 3-, Phi) has increasingly been used in many crop systems, including amenity turfgrass, not only as a nutrient source but also as a pesticide and biostimulant. There are, however, conflicting reports of the efficacy and benefits of Phi as a source of P. This study was conducted to determine the rate of uptake, translocation and fate of Phi when applied as a foliar treatment to amenity turfgrass, and to assess its role as a source of P nutrition, determining the effect Phi treatments have on turfgrass growth, P deficiency responses, tissue and soil P accumulations. Analysis of Phi treated turfgrass using High Performance Ion Chromatography determined that Phi is rapidly taken up and translocated, that sequential Phi treatments lead to cumulative increases in meristematic tissues, an increase in soil P levels and no in planta conversion to Pi. In P sufficient rootzones (> 35 ppm), foliar applied Phi increased biomass in shoot, crowns, and roots, but also led to a reduction in root to shoot ratios. In phosphorus deficient rootzones (< 5 ppm), foliar applied Phi led to growth reductions in leaf, crown and root, and repression of P deficiency responses.

Synthesis and Antibacterial Properties of Oligomeric Dehydrogenation Polymer from Lignin Precursors

The lignin precursors of coniferin and syringin were synthesised, and guaiacyl-type and guaiacyl-syringyl-type oligomeric lignin dehydrogenation polymers (DHP and DHP-GS) were prepared with the bulk method. The carbon-13 nuclear magnetic resonance spectroscopy showed that both DHP-G and DHP-GS contained β-O-4, β-5, β-β, β-1, and 5-5 substructures. Extraction with petroleum ether, ether, ethanol, and acetone resulted in four fractions for each of DHP-G (C11–C14) and DHP-GS (C21–C24). The antibacterial experiments showed that the fractions with lower molecular weight had relatively strong antibacterial activity. The ether-soluble fractions (C12 of DHP-G and C22 of DHP-GS) had strong antibacterial activities against E. coli and S. aureus. The C12 and C22 fractions were further separated by preparative chromatography, and 10 bioactive compounds (G1–G5 and GS1–GS5) were obtained. The overall antibacterial activities of these 10 compounds was stronger against E. coli than S. aureus. Compounds G1, G2, G3, and GS1, which had the most significant antibacterial activities, contained β-5 substructures. Of these, G1 had the best antibacterial activity. Its inhibition zone diameter was 19.81 ± 0.82 mm, and the minimum inhibition concentration was 56.3 ± 6.20 μg/mL. Atmospheric pressure chemical ionisation mass spectrometry (APCI-MS) showed that the antibacterial activity of G1 was attributable to a phenylcoumarin dimer, while the introduction of syringyl units reduced antibacterial activity.
Perceptions and Profiles of Young People Regarding Spa Tourism: A Comparative Study of Students from Granada and Aachen Universities

Spa tourism has undergone important changes in recent decades, actively embracing wellness and wellbeing. However, this transition is taking place in different ways in Europe, and this has led to varying perceptions of thermalism that have little to do with its original conception. The main aim of this study was to analyse current perceptions of spa tourism amongst university students, so as to identify profiles and compare the differences between two study cases: Granada (Spain) and Aachen (Germany). For this purpose, we applied a methodology that combines artificial intelligence techniques with questionnaires containing both quantitative and qualitative variables. This enabled us to identify and characterize a series of profiles, so as to acquire detailed knowledge of the perceptions of these students regarding spa tourism in Granada and Aachen. On the basis of the results, the interviewees were grouped together into seven profiles from which we deduced that young Germans from Aachen visit spas more frequently and have a more realistic perception of the thermal sector than young Spanish people from Granada. This situation could limit present and future demand for spas in southern Spain. With this in mind, in this paper we present an updated assessment of the demand for spas amongst university students, in order to design effective geomarketing strategies in two cities with long spa traditions.
Reduced Expression of Annexin A6 Induces Metabolic Reprogramming That Favors Rapid Fatty Acid Oxidation in Triple-Negative Breast Cancer Cells

Simple Summary The expression status of Annexin A6 (AnxA6) has been shown to influence tumor growth, metastasis, and resistance to therapeutic intervention, but the contribution of this tumor suppressor in the metabolic adaptation of basal-like (AnxA6-low) versus mesenchymal-like (AnxA6-high) TNBC subsets remains unclear. The downregulation of AnxA6 in TNBC cells attenuated mitochondrial respiration, glycolytic flux, and cellular ATP production capacity, resulting in a quiescent metabolic phenotype. The overexpression or chronic lapatinib induced the expression of AnxA6 in AnxA6-low TNBC cells and reversed the quiescent phenotype to a more lipogenic/glycolytic phenotype. Interestingly, AnxA6-depletion was associated with rapid fatty acid uptake and oxidation (lypolytic metabolic phenotype) but decreased lipid droplet accumulation. Our data suggest that the expression status of AnxA6 in TNBC cells is associated with distinct metabolic adaptations of basal-like and mesenchymal-like TNBC subsets in response to cellular stress and/or therapeutic intervention. Abstract The ability of cancer cells to alter their metabolism is one of the major mechanisms underlying rapid tumor progression and/or therapeutic resistance in solid tumors, including the hard-to-treat triple-negative breast cancer (TNBC) subtype. Here, we assessed the contribution of the tumor suppressor, Annexin A6 (AnxA6), in the metabolic adaptation of basal-like (AnxA6-low) versus mesenchymal-like (AnxA6-high), as well as in lapatinib-resistant TNBC cells. Using model basal-like and mesenchymal-like TNBC cell lines, we show that TNBC cells also exhibit metabolic heterogeneity. The downregulation of AnxA6 in TNBC cells generally attenuated mitochondrial respiration, glycolytic flux, and cellular ATP production capacity resulting in a quiescent metabolic phenotype. We also show that AnxA6 depletion in mesenchymal-like TNBC cells was associated with a rapid uptake and mitochondrial fatty acid oxidation and diminished lipid droplet accumulation and altered the lipogenic metabolic phenotype of these cells to a lypolytic metabolic phenotype. The overexpression or chronic lapatinib-induced upregulation of AnxA6 in AnxA6-low TNBC cells reversed the quiescent/lypolytic phenotype to a more lipogenic/glycolytic phenotype with gluconeogenic precursors as additional metabolites. Collectively, these data suggest that the expression status of AnxA6 in TNBC cells underlies distinct metabolic adaptations of basal-like and mesenchymal-like TNBC subsets in response to cellular stress and/or therapeutic intervention and suggest AnxA6 as a biomarker for metabolic subtyping of TNBC subsets.
Enhancing the Electrochemical Performance of Ni-Rich LiNi0.88Co0.09Al0.03O2 Cathodes through Tungsten-Doping for Lithium-Ion Batteries

The tungsten-doped (0.5 and 1.0 mol%) LiNi0.88Co0. 09Al0.03O2 (NCA) cathode materials are manufactured to systematically examine the stabilizing effect of W-doping. The 1.0 mol% W-doped LiNi0.88Co0. 09Al0.03O2 (W1.0-NCA) cathodes deliver 173.5 mAh g−1 even after 100 cycles at 1 C, which is 95.2% of the initial capacity. While the capacity retention of NCA cathodes cycled in identical conditions is 86.3%. The optimal performances of the W1.0-NCA could be ascribed to the suppression of impendence increase and the decrease in anisotropic volume change, as well as preventing the collapse of structures during cycling. These findings demonstrate that the W-doping considerably enhances the electrochemical performance of NCA, which has potential applications in the development of Ni-rich layered cathode materials that can display high capacity with superior cycling stability.
Stages, Periods, and Radiocarbon: 14C Dating in the Archaeology of the Central Andes

Some of the earliest archaeological materials radiocarbon-dated were from the Central Andes, and archaeologists from the region were also involved in early efforts at meta-analysis of assemblages of radiocarbon dates and Bayesian chronological modeling. Nevertheless, regional chronological schema still vary surprisingly little from their pre-radiocarbon antecedents. As a result, significant scope for increasing the impact of radiocarbon dates, as well as making their use more robust and transparent, remains. Improved use of radiocarbon dates has the potential to reconfigure Central Andean chronologies, suiting them better to addressing many of the questions that archaeologists wish to ask. With this in mind, I here review the history of use of 14C dating in the archaeology of the Central Andes, before focusing on practical issues that confront archaeologists working in the region as they both employ 14C dates and seek to be informed and critical consumers of published 14C dates and chronologies.
Learning-based localization in wireless and sensor networks

Accurately tracking mobile devices in wireless and sensor networks using received-signal-strength (RSS) values is a useful task in robotics and activity recognition. It is also a difficult task since radio signals usually attenuate in a highly nonlinear and uncertain way in a complex environment where client devices may be moving. Many existing RSS localization systems suffer from the following problems: first, many of them are inaccurate. Second, to increase their accuracy, many require costly manual calibration. Third, many of them cannot cope with changing data as users move in a dynamic environment. In this thesis, we will describe our learning-based solution using kernels, manifolds and graph Laplacian for solving the these problems. We will demonstrate the effectiveness of our algorithms for tracking static and mobile devices in complex indoor environments using wireless local area network, wireless sensor networks and radio frequency identification networks with much less calibration effort.
Tolerance Screening for Phytophthora capsici and Fusarium solani f. sp. cucurbitae in Cucurbita spp. and Gene Expression Responses in Mutant Families

Cucurbita species can be affected by soil-borne pathogens, such as Phytopthora capsici and Fusarium solani f. sp. cucurbitae (Fsc). Diverse commercial and conserved lines of Cucurbita spp. were tested. C. pepo subsp. pepo genotypes showed the highest susceptibility to both pathogens. The tolerance to P. capsici and Fsc was then screened in a zucchini mutant population. Two M3 mutant lines (Cp107 and Cp116) with a high occurrence of tolerant individuals to Phytophthora capsici were obtained from a screening of 160 M2 mutant lines. The M3 lines presented higher tolerance than the background MUCU-16. Furthermore, in the inoculated samples, both mutants overexpressed CpDEF and expressed more CpPAL and CpChiIV than the susceptible control. It has been previously shown that this expression pattern could be associated with tolerance in the P. capsici - Cucurbita spp. pathosystem. The M3 lines obtained could be applied in breeding programs, as they are likely to be compatible with the highly susceptible C. pepo subsp. pepo genotype.
Excellent Energy Storage Performance in Bi(Fe0.93Mn0.05Ti0.02)O3 Modified CaBi4Ti4O15 Thin Film by Adjusting Annealing Temperature

Dielectric capacitors with ultrahigh power density are highly desired in modern electrical and electronic systems. However, their comprehensive performances still need to be further improved for application, such as recoverable energy storage density, efficiency and temperature stability. In this work, new lead-free bismuth layer-structured ferroelectric thin films of CaBi4Ti4O15-Bi(Fe0.93Mn0.05Ti0.02)O3 (CBTi-BFO) were prepared via chemical solution deposition. The CBTi-BFO film has a small crystallization temperature window and exhibits a polycrystalline bismuth layered structure with no secondary phases at annealing temperatures of 500–550 °C. The effects of annealing temperature on the energy storage performances of a series of thin films were investigated. The lower the annealing temperature of CBTi-BFO, the smaller the carrier concentration and the fewer defects, resulting in a higher intrinsic breakdown field strength of the corresponding film. Especially, the CBTi-BFO film annealed at 500 °C shows a high recoverable energy density of 82.8 J·cm−3 and efficiency of 78.3%, which can be attributed to the very slim hysteresis loop and a relatively high electric breakdown strength. Meanwhile, the optimized CBTi-BFO film capacitor exhibits superior fatigue endurance after 107 charge–discharge cycles, a preeminent thermal stability up to 200 °C, and an outstanding frequency stability in the range of 500 Hz–20 kHz. All these excellent performances indicate that the CBTi-BFO film can be used in high energy density storage applications.
