description: Successful football performance primarily depends on the players’ adaptability to uncertainty. In competition, coaches organise players in lines to enhance collective tactical patterns and reduce this uncertainty, whereas, in practice, they design alternative scenarios to modify footballers’ possibilities of (inter)action and compel them to readjust. This study compared the consequences of playing with two balls on the motor behaviour of two academy football teams. Forty-four highly trained, developmental players from U14 and U16 teams of the same club took part in the study, which consisted of two simulated, 60-minute football matches (ten vs ten plus goalkeepers) with all the official regulatory conditions. Both teams used their regular 1-4-4-2 formation. Using a GPS, team lines’ tactical and conditional performances were obtained from positional data. Mann-Whitney U, with Eta squared (η2) effect size, and t-test, with Cohen’s d (Cohen, 1988), were used to check the impact of the extra ball on the distances between lines and the total and high-speed running (above 4.6 m/s for U14, and 4.9 m/s for U16 [Goto et al., 2015]) distances travelled by each line. The following tactical results were found for both categories: the distances between the goalkeepers and the defensive lines were much shorter when playing with two balls (U14: p < .0001; η2 = .163; U16: p < .0001; η2 = .32), while the distances between defensive and mid-fielding lines grew longer (U14: p < .0001; η2 = .164; U16: p < .0001; η2 = .396) with the extra ball. However, the distance between midfielders and strikers decreased trivially for U14 (p = .0008; η2 = .001) and increased moderately for U16 (p < .0001; η2 = .133) during the two-ball condition. In regards to the distances travelled, the midfielders of both teams ran much longer distances at high speed (U14: p = .047; d = 0.85; U16: p = .02; d = 1.09), and the strikers overall (U14: p = .03, d = 1.92; U16: p = .04, d = 1.82) with the extra ball. U16 defenders (p = .02, d = 1.06) and midfielders (p = .02, d = 1.09) also ran much more when playing with two balls. Coaches can use a second ball to break predetermined team formations and challenge defenders and strikers to solve near-to-goal game situations, while midfielders perform more box-to-box transitions to connect with their teammates. The collective uncertainty generated by this extremely odd extra ball can foster adaptability between the members of a line and between the lines, forcing them to deal with more possibilities of (inter)action.

description: Special arithmetic series $f(x)=\sum_{n=0}^{\infty}c_nx^n$, whose coefficients $c_n$ are normally given as certain binomial sums, satisfy "self-replicating" functional identities. For example, the equation $$\frac1{(1+4z)^2}f\biggl(\frac{z}{(1+4z)^3}\biggr)=\frac1{(1+2z)^2}f\biggl(\frac{z^2}{(1+2z)^3}\biggr)$$ generates a modular form $f(x)$ of weight 2 and level 7, when a related modular parametrization $x=x(τ)$ is properly chosen. In this note we investigate the potential of describing modular forms by such self-replicating equations as well as applications of the equations that do not make use of the modularity. In particular, we outline a new recipe of generating AGM-type algorithms for computing $π$ and other related constants. Finally, we indicate some possibilities to extend the functional equations to a two-variable setting.

description: The influence of photon-momentum recoil on adiabatic population transfer in an atomic three-level lambda system is studied. It is shown that the Doppler frequency shifts, due to atomic motion can play an important role in adiabatic population transfer processes of atomic internal states by a pair of laser fields. For the limiting case of slow atoms ( Doppler shift much smaller than the photon recoil energy) the atoms occupy the same target state regardless of the order of switching of laser fields, while for the case of fast atoms interacting with the intuitive sequence of pulses, the target state is the intermediate atomic state. It is shown that these processes are robust with respect to parameter fluctuations, such as the laser pulse area and the relative spatial offset (delay) of the laser beams. The obtained results can be used for the control of temporal evolution of atomic populations in atomic beams by externally adjustable Doppler shifts.

description: Purpose: For those who stutter, verbal communication is typically compromised in social situations. This may attract negative responses from listeners and stigmatization by society. These have the potential to impair health-related quality of life across a range of domains, including qualitative and quantitative impacts on speech output, mental health issues, and failure to attain educational and occupational potential. These systematic reviews were designed to explore this matter using traditional health economics perspectives of utility measures and cost of illness.Method: Studies were included if they involved children, adolescents, or adults with stuttering as a primary diagnosis. The quality of life search strategy identified 2,607 reports, of which three were included in the quality of life analysis. The cost of illness search strategy identified 3,778 reports, of which 39 were included in the cost of illness analysis.Results: Two of the three studies included in the quality of life analysis had a high risk of bias. When measured using utility scores, quality of life for people who stutter was in the range of those reported for chronic health conditions such as diabetes mellitus, cardiovascular disease, and cancer. However, there is little such evidence of quality of life impairment during the preschool years. Studies included in the cost of illness analysis carried considerable risk of bias overall.Conclusions: For people who stutter, there are substantive direct and indirect costs of illness. These include impairment, challenges, and distress across many domains throughout life, including income, education, employment, and social functioning. Evidence of quality of life impairment using utility measures is extremely limited. If this situation is not remedied, the lifetime impairment, challenges, and distress experienced by those who stutter cannot be documented in a form that can be used to influence health policy and health care spending.Supplemental Material S1.

description: When engaging in playful motor experiences, students display all dimensions of their motor conduct, with the emotional dimension being particularly prominent and relevant in the educational context (Lagardera & Lavega, 2004). Unlike sports, traditional games, such as tail tag, offer more diverse and enriching models of human communication (Martínez-Santos et al., 2020). Tail tag, in particular, is characterised by its instability (i.e., alliances, friendships, and antagonisms that change over time) and lack of an interruption mechanism (i.e., a game without memory). Therefore, the aim of the study was to assess the consequences on the emotional dimension of young primary education students during an unstable motor game without memory, such as tail tag. Forty Spanish students from two fifth-grade primary education classes, 16 girls and 24 boys, participated in the study. The students of each class played tail tag for ten uninterrupted minutes in a 15 m × 14 m rectangle. Tail tag is a traditional game based on capturing the other players' tails while keeping their tails safe. After the game, participants were asked to individually declare the emotion they experienced most intensely, choosing one of nine different emotions: four positive ones (joy, humour, affection and happiness) and five negative ones (sadness, fear, anger, shame and rejection), by the Games and Emotions Scale for Children (GES-C). GES-C has been validated in primary school students aged eight to 12 (Alcaraz-Muñoz et al., 2022). Students participated in a familiarisation session before playing tail tag. The chi-square test was used to analyse the frequency of the emotion they experienced most intensely and to compare girls and boys. Emotions declared were not equiprobable: joy, anger and happiness supposed 95% of the most salient, vivid emotions felt by the students (p < .001). Likewise, positive emotions (77.5%) were more intensely felt (p = .001) than negative ones (22.5%). The emotion (p = .45) and the type of emotion (p = .22) most felt by boys and girls were similar. These results suggest that the emotional experience elicited by tail tag (i.e., an unstable motor game without memory) can be predicted to be predominantly positive in primary education students, for both girls and boys and interpreted in relation to the structural traits of the situation generated. Therefore, this information can be utilised by physical education teachers to design teaching strategies that foster pupils’ emotional well-being.

description: We propose a new physical interpretation of the Diophantine equation of $σ_{xy}$ for the Hofstadter problem. First, we divide the energy spectrum, or Hofstadter's butterfly, into smaller self-similar areas called "subcells", which were first introduced by Hofstadter to describe the recursive structure. We find that in the energy gaps between subcells, there are two ways to account for the quantization rule of $σ_{xy}$, that are consistent with the Diophantine equation: Landau quantization of (i) massless Dirac fermions or (ii) free fermions in Hofstadter's butterfly.

description: Ability to apply mathematical knowledge to problem solving is achieved by confronting students with real-life challenges in the context of word problems. Therefore, the ability of students to solve word problems is one of the goals of educational systems. In this regard, the present study sought to identify the challenges of solving the word problems of fractions in students at the end of elementary school. For this purpose, eight boys and girls, volunteerely participated in a study they were interviewed using task-based interview technique and the data collected through six mathematical word problems related to fraction. The data were analysed using inductive content analysis and sub-themes and themes, were explained accordingly. The themes and sub-thems helped to identify 10 main challenges that students were facing while solving fractions’ word problems as major findings of this study. These challenges were changes in sentence structure, computational errors in fractions, misconceptions regarding fraction concept, students’ beliefs about mathematical problems, limited views regarding problem solving, dominance of procedural learning over relational learning, low self-esteem about problem solving and effects of emotional factors in solving problems and conceptual difficulties. Based on these findings, the conclusion is that students face cognitive, emotional and linguistic challenges in solving fraction word problems. Thus the concluding remark is that to help students overcome these challenges, there is a need to make some in further reforms in mathematics curriculum and teaching methods, these challenges should ba considered.

description: Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here we clarify the origin of wetting hysteresis for a liquid front advancing or receding across an isolated defect of nanometric size. Various kinds of chemical and topographical nanodefects are investigated which represent salient features of actual heterogeneous surfaces. The most probable wetting path across surface heterogeneities is identified by combining, within an innovative approach, microscopic classical density functional theory and the string method devised for the study of rare events. The computed rugged free energy landscape demonstrates that hysteresis emerges as a consequence of metastable pinning of the liquid front at the defects; the barriers for thermally activated defect crossing, the pinning force, and hysteresis are quantified and related to the geometry and chemistry of the defects allowing for the occurrence of nanoscopic effects. The main result of our calculations is that even weak nanoscale defects, which are difficult to characterize in generic microfluidic experiments, can be the source of a plethora of hysteretical phenomena, including the pinning of nanobubbles.

description: The two-dimensional dissipative quantum XY model is applicable to the quantum-critical properties of diverse experimental systems, ranging from the superconductor to insulator transitions, ferromagnetic and antiferromagnetic transitions in metals, to the loop-current order transition in the cuprates. We solve the re-expression of this model in terms of topological excitations: vortices and a variety of instantons, by renormalization group methods. The calculations explain the extraordinary properties of the model discovered in Monte-Carlo calculations: the separability of the quantum critical fluctuations (QCF) in space and time, the spatial correlation length proportional to logarithm of the temporal correlation length near the transition from disordered to the fully ordered state, and the occurrence of a phase with spatial order without temporal order. They are intimately related to the flow of the metric of time in relation to the metric of space, i.e. of the dynamical critical exponent $z$. These properties appear to be essential in understanding the strange metallic phase found in a variety of quantum-critical transitions as well as the accompanying high temperature superconductivity.

description: The Kalman filter is an established tool for the analysis of dynamic systems with normally distributed noise, and it has been successfully applied in numerous application areas. It provides sequentially calculated estimates of the system states along with a corresponding covariance matrix. For nonlinear systems, the extended Kalman filter is often used which is derived from the Kalman filter by linearization around the current estimate. A key issue in metrology is the evaluation of the uncertainty associated with the Kalman filter state estimates. The "Guide to the Expression of Uncertainty in Measurements" (GUM) and its supplements serve as the de facto standard for uncertainty evaluation in metrology. We explore the relationship between the covariance matrix produced by the Kalman filter and a GUM-compliant uncertainty analysis. In addition, also the results of a Bayesian analysis are considered. For the case of linear systems with known system matrices, we show that all three approaches are compatible. When the system matrices are not precisely known, however, or when the system is nonlinear, this equivalence breaks down and different results can be reached then. Though for precisely known nonlinear systems the result of the extended Kalman filter still corresponds to the linearized uncertainty propagation of GUM. The extended Kalman filter can suffer from linearization and convergence errors. These disadvantages can be avoided to some extent by applying Monte Carlo procedures, and we propose such a method which is GUM-compliant and can also be applied online during the estimation. We illustrate all procedures in terms of a two-dimensional dynamic system and compare the results with those obtained by particle filtering, which has been proposed for the approximate calculation of a Bayesian solution. Finally, we give some recommendations based on our findings.

description: We calculate the orbital magnetic susceptibility $χ_{\mathrm{orb}}$ for an 8-band tight-binding model of gapless and gapped graphene using Green's functions. Analogously, we study $χ_{\mathrm{orb}}$ for a $\mathrm{MoS_2}$ 12-band model. For both materials, we unravel the character of the processes involved in the magnetic response by looking at the contribution at each point of the Brillouin zone. By this, a clear distinction between intra- and interband excitations is generally possible and we are able to predict qualitative features of $χ_{\mathrm{orb}}$ only through the knowledge of the band structure. The study is complemented by comparing the magnetic response with that of 2-band lattice Hamiltonians which reduce to the Dirac and Bernevig-Hughes-Zhang (BHZ) models in the continuum limit.

description: The Pauli Exclusion Principle (PEP) was introduced by the austrian physicist Wolfgang Pauli in 1925. Since then, several experiments have checked its validity. From 2006 until 2010, the VIP (VIolation of the Pauli Principle) experiment took data at the LNGS underground laboratory to test the PEP. This experiment looked for electronic 2p to 1s transitions in copper, where 2 electrons are in the 1s state before the transition happens. These transitions violate the PEP. The lack of detection of X-ray photons coming from these transitions resulted in a preliminary upper limit for the violation of the PEP of $4.7 \times 10^{-29}$. Currently, the successor experiment VIP2 is under preparation. The main improvements are, on one side, the use of Silicon Drift Detectors (SDDs) as X-ray photon detectors. On the other side an active shielding is implemented, which consists of plastic scintillator bars read by Silicon Photomultipliers (SiPMs). The employment of these detectors will improve the upper limit for the violation of the PEP by around 2 orders of magnitude.

description: For the laser wakefield acceleration, suppression of beam energy spread while keeping sufficient charge is one of the key challenges. In order to achieve this, we propose bichromatic laser ionization injection with combined laser wavelengths of $2.4\rm μm$ and $0.8\rm μm$ for wakefield excitation and for triggering electron injection via field ionization, respectively. A laser pulse at $2.4\rm μm$ wavelength enables one to drive an intense acceleration structure with relatively low laser power. To further reduce the requirement of laser power, we also propose to use carbon dioxide as the working gas medium, where carbon acts as the injection element. Our full three dimensional particle-in-cell simulations show that electron beams at the GeV energy level with both low energy spreads (around one percent) and high charges (several tens of picocoulomb) can be obtained by this scheme with laser parameters achievable in the near future.

description: This article aims to present Paralympic athlete Mario Trindade’s training to become the European Champion at the 100-meter wheelchair race in Berlin 2018. The lack of information on this specific training has impaired the beginning of this journey. However, the daily monitoring of this athlete over 20 years has permitted us to realise that the training methods of athletes with disabilities are not very different from those of others. Thus, it is important to understand the different responses to exercise. The degree of improvement after a training program depends on the characteristics of the vertebral-medullary lesion, the training history, and the training ability of the athlete, which is determined by the amount of active muscle mass available. Considering these aspects, we aim to describe the summer training macrocycle that is developed for the 100 m wheelchair race, which is a combined work developed by a multidisciplinary team. We will start by providing a theoretical background on para-athletics events, specifically wheelchair competitions. Afterwards, we will characterise the athlete and discuss his track and strength training, which prepared him to obtain the gold medal in 2018.

description: In this work we study theoretically the properties of S-F/N-sIS type Josephson junctions in the frame of the quasiclassical Usadel formalism. The structure consists of two superconducting electrodes (S), a tunnel barrier (I), a combined normal metal/ferromagnet (N/F) interlayer and a thin superconducting film (s). We demonstrate the breakdown of a spatial uniformity of the superconducting order in the s-film and its decomposition into domains with a phase shift $π$ . The effect is sensitive to the thickness of the s layer and the widths of the F and N films in the direction along the sIS interface. We predict the existence of a regime where the structure has two energy minima and can be switched between them by an electric current injected laterally into the structure. The state of the system can be non-destructively read by an electric current flowing across the junction.

description: Being aware of the relevance of physical exercise in individuals with Intellectual and Developmental Disabilities (IDD), we intend to conduct a brief review on the importance of regular physical exercise for this population. An approach will be taken in order to acknowledge the barriers to the high rates of sedentary lifestyles in this population, the potential benefits of physical exercise, and the essential aspects for a correct assessment, prescription, and implementation of these programs in the population with IDD, through a reflection supported by scientific evidence. The current overview aims to provide relevant information regarding the health benefits of physical exercise in individuals with IDD, as the basis for QoL promoting more active and healthier lifestyles, namely through structured physical exercise. In addition, it is also a useful tool for consultation by exercise professionals since adjusted indoor and outdoor exercise programs are listed.

description: We present Herschel, ALMA Compact Array (ACA), and Caltech Submillimeter Observatory (CSO) observations of the prestellar core in L1689N, which has been suggested to be interacting with a molecular outflow driven by the nearby solar type protostar IRAS 16293-2422. This source is characterized by some of the highest deuteration levels seen in the interstellar medium. The change in the NH2D line velocity and width across the core provides clear evidence of an interaction with the outflow, traced by the high-velocity water emission. Quiescent, cold gas, characterized by narrow line widths is seen in the NE part of the core, while broader, more disturbed line profiles are seen in the W/SW part. Strong N2D+ and ND3 emission is detected with the ACA, extending S/SW from the peak of the single-dish NH2D emission. The ACA data also reveal the presence a compact dust continuum source, with a mean size of ~1100 au, a central density of (1-2) 10^7 cm-3, and a mass of 0.2-0.4 Msun. The dust emission peak is displaced ~5" to the south with respect to the N2D+ and ND3 emission, as well as the single-dish dust continuum peak, suggesting that the northern, quiescent part of the core is characterized by spatially extended continuum emission, which is resolved out by the interferometer. We see no clear evidence of fragmentation in this quiescent part of the core, which could lead to a second generation of star formation, although a weak dust continuum source is detected in this region in the ACA data.

Linear and nonlinear ion-acoustic waves in non-relativistic quantum plasmas with arbitrary degeneracy

description: Linear and nonlinear ion-acoustic waves are studied in a fluid model for non-relativistic, unmagnetized quantum plasma with electrons with an arbitrary degeneracy degree. The equation of state for electrons follows from a local Fermi-Dirac distribution function and apply equally well both to fully degenerate or classical, non-degenerate limits. Ions are assumed to be cold. Quantum diffraction effects through the Bohm potential are also taken into account. A general coupling parameter valid for dilute and dense plasmas is proposed. The linear dispersion relation of the ion-acoustic waves is obtained and the ion-acoustic speed is discussed for the limiting cases of extremely dense or dilute systems. In the long wavelength limit the results agree with quantum kinetic theory. Using the reductive perturbation method, the appropriate Korteweg-de Vries equation for weakly nonlinear solutions is obtained and the corresponding soliton propagation is analyzed. It is found that soliton hump and dip structures are formed depending on the value of the quantum parameter for the degenerate electrons, which affect the phase velocities in the dispersive medium.

description: We present a numerical study on the light transport properties and statistics of transmission channels in random media with inhomogeneous disorder. For the case of longitudinal inhomogeneity of disorder we find that the statistics of the transmission channels is independent of the inhomogeneity and the system can be equivalent to a counterpart with homogeneous disorder strength, both of which have the same statistical distribution of the transmission channels. However, for the case of transverse inhomogeneity of disorder, such equivalence does not exist, moreover, the transmission eigenvalues are pushed to the two ends of the distribution and the distribution of the total transmission is broadened since the spatial structure gives rise to larger and smaller transmitted incident channels.

Cognitive Stimulation and Dementia: Traditional Interventions vs. Computer-Based Methodologies
Creators: name: Mendes, Liliana
Publisher: name: Motricidade

description: We aim to examine the role of cognitive stimulation interventions applied to healthy older adults or older adults with mild-to-moderate dementia. The most important benefits and differences between using these programs without computerised tasks compared to computer-based assistive technologies are also addressed. We conducted a literature review which includes empirical studies in the cognitive stimulation field, applied to healthy older adults or in participants with some type of dementia. All studies include cognitive stimulation intervention using traditional methods or computer-based assistive technology. We included a total of 35 studies in our review. In general, our findings provide support for applying cognitive stimulation programs, using traditional methods or computer-based assistive technology, specifically for older people with dementia. However, we found heterogeneity regarding methods, design of intervention, and procedures in both types of methodology.

This review adds value towards a systematisation of heterogeneous data existing in this field. However, it remains difficult to perform unbiased comparisons. Future studies should provide a comparative assessment of the effectiveness of cognitive stimulation programs using computer-based assistive technology involving older adults at various stages of dementia, as well as the efficacy and reliability of this type of intervention, practical effects and the potential to delay or prevent dementia.

description: Visually impaired people face important challenges related to orientation and mobility. Indeed, 56% of visually impaired people in France declared having problems concerning autonomous mobility. These problems often mean that visually impaired people travel less, which influences their personal and professional life and can lead to exclusion from society. Therefore this issue presents a social challenge as well as an important research area. Accessible geographic maps are helpful for acquiring knowledge about a city's or neighborhood's configuration, as well as selecting a route to reach a destination. Traditionally, raised-line paper maps with braille text have been used. These maps have proved to be efficient for the acquisition of spatial knowledge by visually impaired people. Yet, these maps possess significant limitations. For instance, due to the specificities of the tactile sense only a limited amount of information can be displayed on a single map, which dramatically increases the number of maps that are needed. For the same reason, it is difficult to represent specific information such as distances. Finally, braille labels are used for textual descriptions but only a small percentage of the visually impaired population reads braille. In France 15% of blind people are braille readers and only 10% can read and write. In the United States, fewer than 10% of the legally blind people are braille readers and only 10% of blind children actually learn braille. Recent technological advances have enabled the design of interactive maps with the aim to overcome these limitations. Indeed, interactive maps have the potential to provide a broad spectrum of the population with spatial knowledge, irrespective of age, impairment, skill level, or other factors. To this regard, they might be an efficient means for providing visually impaired people with access to geospatial information. In this paper we give an overview of our research on making geographic maps accessible to visually impaired people.

description: We present a unified model describing electroweak properties of the pi and rho mesons. Using a general method of relativistic parametrization of matrix elements of local operators, adjusted for the nondiagonal in total angular momentum case, we calculate the rho-meson lepton-decay constant f_rho using the same parameters of free constituent quarks that have ensured exclusively good results for the pi meson previously. The only free parameter, characterizing quark interactions, which include additional spin-spin contribution and hence differ from the $π$-meson case, is fixed by matching the decay constant to its experimental value. The mean square charge radius is calculated, =(0.56+-0.04) fm^2. This result verifies, for the rho-meson case, the conjecture of equality between electromagnetic and strong radii of hadrons tested previously for proton, pi and K mesons.

description: We present a novel hierarchical approach to multi-class classification which is generic in that it can be applied to different classification models (e.g., support vector machines, perceptrons), and makes no explicit assumptions about the probabilistic structure of the problem as it is usually done in multi-class classification. By adding a cascade of additional classifiers, each of which receives the previous classifier's output in addition to regular input data, the approach harnesses unused information that manifests itself in the form of, e.g., correlations between predicted classes. Using multilayer perceptrons as a classification model, we demonstrate the validity of this approach by testing it on a complex ten-class 3D gesture recognition task.
