description: The recent success of graph neural networks has significantly boosted molecular property prediction, advancing activities such as drug discovery. The existing deep neural network methods usually require large training dataset for each property, impairing their performances in cases (especially for new molecular properties) with a limited amount of experimental data, which are common in real situations. To this end, we propose Meta-MGNN, a novel model for few-shot molecular property prediction. Meta-MGNN applies molecular graph neural network to learn molecular representation and builds a meta-learning framework for model optimization. To exploit unlabeled molecular information and address task heterogeneity of different molecular properties, Meta-MGNN further incorporates molecular structure, attribute based self-supervised modules and self-attentive task weights into the former framework, strengthening the whole learning model. Extensive experiments on two public multi-property datasets demonstrate that Meta-MGNN outperforms a variety of state-of-the-art methods.

description: We report new measurements and calculations of the non-resonant inelastic x-ray scattering (NRIXS) from Mg and Al for a wide range of momentum transfers, q. Extended oscillations in the dynamic structure factor S(q,w) due to scattering from the 2p and 2s orbitals (i.e. L-edges) are observed out to more than 150 eV past the binding energy. These results are discussed in context of the recently proposed representation of S(q,w) for core shells as an atomic background modulated by interference between different photoelectron scattering paths, in analogy to the standard treatment of extended x-ray absorption fine structure. In agreement with this representation, we find a strong increase in the atomic background with increasing q with a concomitant enhancement in the amplitude of the extended fine structure. This effect should be generic and hence may enable improved measurement of the extended fine structure in a wide range of materials containing low-Z elements.

description: We analyze a recent protocol for the transmission of quantum states via a dual spin chain [Burgarth and Bose, Phys. Rev. A 71, 052315 (2005)] under the constraint that the receiver's measurement strength is finite. That is, we consider the channel where the ideal, instantaneous and complete von Neumann measurements are replaced with a more realistic continuous measurement. We show that for optimal performance the measurement strength must be "tuned" to the channel spin-spin coupling, and once this is done, one is able to achieve a similar transmission rate to that obtained with ideal measurements. The spin chain protocol thus remains effective under measurement constraints.

description: To analyze the correlation between body weight, body mass index (BMI), fat mass (FM), lean mass (LM), and biochemical indicators at various stages of physical training, and to investigate the relationship between bone mineral density (BMD), body composition, and biochemical indicators. This research aims to provide insights for the scientific training of Chinese handicapped snowboarding athletes. Utilizing 12 male athletes from the Chinese National Handicapped Team as participants, this study implemented an eight-week physical training regimen consisting of three phases: endurance training, maximum strength training, and rapid strength training. Body composition and BMD were assessed using dual-energy X-ray absorptiometry. Blood analysis was conducted to measure biochemical indicators such as ferritin (Fer), calcium (Ca), phosphorus (P), magnesium (Mg), and other relevant parameters. Results: 1) The athletes demonstrated an increase in body weight, LM, FM, and BMD. 2) The BMD of the athletes exhibited a moderate inverse correlation with LM and FM in all regions except the trunk and android region, as well as body weight. Additionally, the concentrations of Ca, calcium-phosphorus product (Ca×P), and Fer showed a moderate positive association with the BMD of the athletes.

description: Horizontal deceleration is a common movement in team sports involving rapid velocity changes, and is characterized by high impact forces and loading rates. Dynamic balance is crucial for maintaining a stable posture during horizontal deceleration performance; however, whether lower-limb balance asymmetries would affect horizontal deceleration performance in young athletes is unclear. This study aimed to explore whether the lower-limb asymmetry measured from the Y-balance test affects horizontal deceleration performance at different distances in youth elite basketball players.

description: The task of learning to rank has been widely studied by the machine learning community, mainly due to its use and great importance in information retrieval, data mining, and natural language processing. Therefore, ranking accurately and learning to rank are crucial tasks. Context-Based Information Retrieval systems have been of great importance to reduce the effort of finding relevant data. Such systems have evolved by using machine learning techniques to improve their results, but they are mainly dependent on user feedback. Although information retrieval has been addressed in different works along with classifiers based on Optimum-Path Forest (OPF), these have so far not been applied to the learning to rank task. Therefore, the main contribution of this work is to evaluate classifiers based on Optimum-Path Forest, in such a context. Experiments were performed considering the image retrieval and ranking scenarios, and the performance of OPF-based approaches was compared to the well-known SVM-Rank pairwise technique and a baseline based on distance calculation. The experiments showed competitive results concerning precision and outperformed traditional techniques in terms of computational load.

description: The dynamics of sytems that can be mapped to a four-well problem in the presence of a dissipative environment is examined. The probabilities of finding the systems in one of the four state as a function of time are found in the limit of overdamped oscillations. Also in this limit, the time evolution of the density matrix of a four-well system is found. The diagonals elements are then rederived by considering an infinite chain of wells.

description: With the development of urbanization, the existing space within city schools is increasingly inadequate to meet the growing demand for recess activities. The evidence indicates that environmental cues can prompt individuals to consider becoming more active. Due to the capability of GIS (Geographic Information System) to objectively reflect, analyze, and plan activity spaces, a previous study reported that walking maps based on GIS can prompt the physical activity (PA) levels of community residents. This study aims to investigate the effectiveness of walking maps based on GIS in enhancing PA during unstructured recess among high school students.

description: Non-target screening consists in searching a sample for all present substances, suspected or unknown, with very little prior knowledge about the sample. This approach has been introduced more than a decade ago in the field of water analysis, together with dedicated compound identification tools, but is still very scarce for indoor and atmospheric trace gas measurements, despite the clear need for a better understanding of the atmospheric trace gas composition.For a systematic detection of emerging trace gases in the atmosphere, a new and powerful analytical method is gas chromatography (GC) of preconcentrated samples, followed by electron ionisation, high resolution mass spectrometry (EI-HRMS). In this work, we present data analysis tools to enable automated fragment formula annotation for unknown compounds measured by GC-EI-HRMS. Based on co-eluting mass/charge fragments, we developed an innovative data analysis method to reliably reconstruct the chemical formulae of the fragments, using efficient combinatorics and graph theory. The method does not require the presence of the molecular ion, which is absent in ~40% of EI spectra. Our method has been trained and validated on \textgreater50 halocarbons and hydrocarbons, with 3 to 20 atoms and molar masses of 30 to 330 g mol-1, measured with a mass resolution of approx.~3500. For 90% of the compounds, more than 90% of the annotated fragment formulae are correct. Cases of wrong identification can be attributed to the scarcity of detected fragments per compound or the lack of isotopic constraint (no minor isotopocule detected).Our method enables to reconstruct most probable chemical formulae independently from spectral databases. Therefore, it demonstrates the suitability of EI-HRMS data for non-target analysis and paves the way for the identification of substances for which no EI mass spectrum is registered in databases. We illustrate the performances of our method for atmospheric trace gases and suggest that it may be well suited for many other types of samples. The L-GPL licenced Python code is released under the name ALPINAC for ALgorithmic Process for Identification of Non-targeted Atmospheric Compounds.

description: During exercise, individuals inevitably lose electrolytes and fluids. In such circumstances, simply replenishing water may not maintain the body's fluid balance. Therefore, individuals need to replenish with appropriate sports drinks at the right time. However, research has shown that there are misconceptions or incomplete understandings among the population regarding sports drinks, neglecting the risks they may pose, such as hypertension, tachycardia, and anxiety. It is also important to note that some groups are not suitable for consuming sports drinks. This article will summarize the proven effective ingredients of sports drinks and their proper usage, including timing and quantity. Additionally, it will provide an overview of recent developments in sports drinks and explore the potential of natural beverages such as milk and coconut water as sports drinks. Finally, the article will discuss the current limitations in the design of sports drinks and potential improvement measures.

description: We present results from a weak lensing analysis of the galaxy cluster A1689 (z=0.183) based on deep wide-field imaging data taken with Suprime-Cam on Subaru telescope. A maximum entropy method has been used to reconstruct directly the projected mass distribution of A1689 from combined lensing distortion and magnification measurements of red background galaxies.The resulting mass distribution is clearly concentrated around the cD galaxy, and mass and light in the cluster are similarly distributed in terms of shape and orientation. The azimuthally-averaged mass profile from the two-dimensional reconstruction is in good agreement with the earlier results from the Subaru one-dimensional analysis of the weak lensing data, supporting the assumption of quasi-circular symmetry in the projected mass distribution of the cluster.

Kinetic theory with angle-action variables

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We present a kinetic theory for inhomogeneous systems with weak long-range interactions. Starting from the Klimontovich equation and using a quasilinear theory, we obtain a closed kinetic equation describing the relaxation of the distribution function of the system as a whole due to resonances between different orbits. This equation is written in angle-action variables. It conserves mass and energy and increases the Boltzmann entropy (H-theorem). Using a thermal bath approximation, we derive a Fokker-Planck equation that describes the relaxation of a test particle towards the Boltzmann distribution under the combined effect of diffusion and friction terms. We mention some analogies with the kinetic theory of point vortices in two-dimensional hydrodynamics. We also stress the limitations of our approach and the connection with recent works.

description: High-resolution image segmentation remains challenging and error-prone due to the enormous size of intermediate feature maps. Conventional methods avoid this problem by using patch based approaches where each patch is segmented independently. However, independent patch segmentation induces errors, particularly at the patch boundary due to the lack of contextual information in very high-resolution images where the patch size is much smaller compared to the full image. To overcome these limitations, in this paper, we propose a novel framework to segment a particular patch by incorporating contextual information from its neighboring patches. This allows the segmentation network to see the target patch with a wider field of view without the need of larger feature maps. Comparative analysis from a number of experiments shows that our proposed framework is able to segment high resolution images with significantly improved mean Intersection over Union and overall accuracy.

description: To maximize student participation within school-based physical activity opportunities requires purposeful collaboration among teachers and other community professionals. Teachers using mountain biking in their physical education programs reported students showing interest in biking opportunities outside of physical education (Blevins, 2019). The purpose of this study was to examine the effect of a mountain biking program on middle school students’ motivation in physical education and to participate in extracurricular biking opportunities. The trans-contextual model of motivation (TCM: Hagger et al, 2003) was used as a theoretical model to examine this relationship.
Studies of the immune network based on shape-space and distance coefficient
Creators: name: Royer, Sophie
Publisher: name: University of British Columbia

description: A selective history of immunology is first presented that tells about the development of the theories of “acquired immunity”, from the early observations of the phenomenon of immunity in the Roman times until the long debate ending in the late 1960’s between the proponents of the theories of “cellular immunity” and those of the theories of “humoral immunity”. Some theories of antibody formation are also reviewed up to the “clonal selection theory”. Then the “immune network hypothesis” and some of the models that it engendered are explained, with a focus on a particular model due to Hoffmann and his co-workers: the N-dimensional network model. A short history of the attempts to model the “affinity” distribution and various choices of “connectivity” matrices is presented, focussed on a particular one: a connectivity matrix based on a one-dimensional “shape space”. The ± shape-space ¹, a shape-space formulated by Segel and Perelson, is reviewed and a “new shape-space without shape zero”, the Δ shape-space, is introduced in which “complementarity” relationships between clones differ from the ones in the + shapespace. Some analysis and numerical simulations of the two different versions of shapespace embedded in Hoffmann’s N-dimensional network are shown, which are the first simulations of the model to have ever been be done with non-Boolean affinities. The concept of a “distance coefficient” is reviewed, analyzed and developed further for its use with non-Boolean affinities. The first numerical simulations of the distance coefficients to have ever been done are presented and analyzed, embedded in Hoffmann’s N-dimensional network model with Boolean and non-Boolean affinities. ¹The author’s renaming of the original shape-space of Segel and Perelson.

description: We present population synthesis models designed to represent the star formation histories of L* red sequence galaxies (RSGs). Earlier work has shown that single-burst stellar populations (SSPs) are unable to match Balmer line strengths simultaneously at high and low redshift. We therefore consider alternative star formation histories in which RSGs contain intermediate-aged stars even at late epochs. The models are compared to Balmer Hdelta absorption strengths, U-B color data, and the number density of red sequence galaxies from z=1 to z=0. We find that quenched models (which consist of constant star formation histories truncated at regularly-spaced intervals) average to an RSG population that matches the data well, showing slow evolution in color and Balmer line strength and a rise in number density by a factor of a few after z=1. The data are best fit by a turn-on of quenching at redshifts z=1.5-2.

description: Pitch passing networks, as a critical tool for studying team collaboration and on-field player interaction, have been increasingly utilized in sports science. This study employs Social Network Analysis (SNA) to delve deeper into the impact of situational factors—such as team quality, match outcomes, and match location—on the England Premier League (EPL) pitch passing networks. The use of SNA is motivated by its ability to reveal the intricate patterns of player interactions and tactical execution within a team, offering a nuanced perspective on collective behavior that can inform strategic decisions. The soccer pitch was divided into 49 zones using a 7x7 grid, with each zone identified by an "x-y" coordinate system that designates the lateral and depth positions on the field. Centrality measures, including degree, closeness, and betweenness centrality, were calculated to determine the strategic importance of each zone within the passing network. Statistical tests were utilized to assess the significance of differences in these measures across various match scenarios. Key findings indicate that strong teams have a higher degree and closeness centrality in central zones, particularly in areas closer to the opponent's goal, suggesting a more effective ball distribution and control in these regions. Betweenness centrality analysis revealed that strong teams predominantly exert control in the front middle area and near their own goal, highlighting their ability to dictate play and create goal-scoring opportunities. In contrast, weak teams showed higher betweenness centrality in the midfield's side zones, which may imply a more peripheral approach to creating chances. The study also observed that home teams, regardless of strength, tend to have higher centrality values in offensive zones, which may be attributed to the home-field advantage. In summary, the central and defensive midfield zones are pivotal in soccer strategy, with strong teams capitalizing on these areas for tactical superiority. The insights from this study are invaluable for soccer analysts and coaches seeking to optimize team performance through targeted tactical adjustments.

description: Modern societies are essentially democratic, if by "democracy" we mean the real exercise of power by a people indivisible and divided into classes. On the contrary, a dominant regime has been imposed by a particular social class, which is imposed by violence through constitutionally enshrined institutions and corresponding subjective legal functions. Institutions such as public administration, the military, the state apparatus, the education system, act as decision makers and transmitters in the name of the nation or state, controlling and oppressing the social body. Especially public education appears as a function without obvious common elements with the current political power, but in reality it is one of the most important levers of support, through mechanisms evident in specialized researchers, showing its real functional existence, the control of the social body through disciplinary systems applied to the entire student population throughout the duration of their studies in them, covered by a protective mantle as a transmitter of accumulated human knowledge

description: We investigate the Liouvillian integrability of Hamiltonian systems describing a universe filled with a scalar field (possibly complex). The tool used is the differential Galois group approach, as introduced by Morales-Ruiz and Ramis. The main result is that the generic systems with minimal coupling are non-integrable, although there still exist some values of parameters for which integrability remains undecided; the conformally coupled systems are only integrable in four known cases. We also draw a connection with chaos present in such cosmological models, and the issues of integrability restricted to the real domain.

description: Experimental and theoretical investigations of undulation patterns in high-pressure, inclined layer gas convection at a Prandtl number near unity are reported. Particular focus is given to the competition between the spatiotemporal chaotic state of undulation chaos and stationary patterns of ordered undulations. In experiments a competition and bistability between the two states is observed, with ordered undulations most prevalent at higher Rayleigh number. The spectral pattern entropy, spatial correlation lengths, and defect statistics are used to characterize the competing states. The experiments are complemented by a theoretical analysis of the Oberbeck-Boussinesq equations. The stability region of the ordered undulation as a function of their wavevectors and the Rayleigh number is obtained with Galerkin techniques. In addition, direct numerical simulations are used to investigate the spatiotemporal dynamics. In the simulations both ordered undulations and undulation chaos were observed dependent on initial conditions. Experiment and theory are found to agree well.

description: Although there is growing recognition of the importance of physical literacy on physical activity participation and health, few studies have examined its impact on academic performance, particularly among college students. To further understand the impact mechanism of physical literacy on academic performance, a double mediation model linking physical literacy and academic performance through physical activity and executive function was constructed. Methods: College students (N = 418) from China completed the Perceived Physical Literacy Instrument, International Physical Activity Questionnaire-Short Form, Short Executive Function Scale and reported demographic information and average GPA. Then a partial least squares structural equation model (PLS-SEM) was constructed since the goal of the model is predicting key target constructs. Results: The model has good reliability, convergent and discriminant validity. Physical literacy and physical activity have positive effects on executive function (β = 0.302, p < 0.001; β = 0.152, p < 0.05). Executive function has positive effects on academic performance (β = 0.171, p < 0.05). Physical literacy has a positive impact on physical activity as well (β = 0.315, p < 0.001). The mediation effects of physical activity and executive function were then further demonstrated by multiple linear regression analysis. In addition, significant differences in multiple domains were found in gender, grade, major, and monthly disposable income. Conclusion: Physical literacy, physical activity and executive function are important roles that can positively affect academic performance. Physical activity and executive function are mediating roles between physical literacy and academic performance. This may explain the heterogeneity of findings in previous studies regarding the effects of physical activity on academic performance. More research could develop practical measures for college students to enhance their physical literacy and final realize the improvement of their academic performance.

description: Continuously monitored atomic spin-ensembles allow, in principle, for real-time sensing of external magnetic fields beyond classical limits. Within the linear-Gaussian regime, thanks to the phenomenon of measurement-induced spin-squeezing, they attain a quantum-enhanced scaling of sensitivity both as a function of time, $t$, and the number of atoms involved, $N$. In our work, we rigorously study how such conclusions based on Kalman filtering methods change when inevitable imperfections are taken into account: in the form of collective noise, as well as stochastic fluctuations of the field in time. We prove that even an infinitesimal amount of noise disallows the error to be arbitrarily diminished by simply increasing $N$, and forces it to eventually follow a classical-like behaviour in $t$. However, we also demonstrate that, "thanks" to the presence of noise, in most regimes the model based on a homodyne-like continuous measurement actually achieves the ultimate sensitivity allowed by the decoherence, yielding then the optimal quantum-enhancement. We are able to do so by constructing a noise-induced lower bound on the error that stems from a general method of classically simulating a noisy quantum evolution, during which the stochastic parameter to be estimated -- here, the magnetic field -- is encoded. The method naturally extends to schemes beyond the linear-Gaussian regime, in particular, also to ones involving feedback or active control.

description: I review a recently proposed scaling analysis of hadron suppression in Deeply Inelastic Scattering on nuclear targets measured at the HERMES experiment. The analysis can distinguish 2 competing explanations for the observed suppression, namely, quark radiative energy loss with long hadron formation times, and prehadron nuclear absorption with hadronization starting inside the nucleus. Experimental data are shown to favor short formation times and prehadron absorption.

description: Muscle atrophy is a disease characterized by a decrease in skeletal muscle mass and strength. In recent years, with the aggravation of population aging and the increase of type 2 diabetes, the incidence rate of muscle atrophy has increased year by year. The occurrence of muscle atrophy can be caused by various factors, such as nerve damage, chronic inflammation, metabolic disorders, etc., which seriously reduces the quality of life of the elderly population and chronic disease patients. As a fat soluble hormone, vitamin D not only plays a crucial role in maintaining bone health, but also plays an important role in regulating muscle function and improving muscle atrophy. After being activated by the liver and kidneys in the body, vitamin D binds to the vitamin D receptor (VDR) to regulate muscle protein synthesis and muscle cell energy metabolism. Research has found that patients with muscle atrophy often suffer from vitamin D deficiency and decreased VDR expression, which may be related to a decline in muscle function. In recent years, studies have shown that supplementing with vitamin D can improve muscle atrophy. Exercise training is considered a crucial intervention for improving muscle atrophy. Studies have found that exercise can upregulate the expression of the vitamin D receptor (VDR) in skeletal muscle, which may be a potential mechanism by which exercise ameliorates muscle atrophy. However, the underlying mechanisms through which exercise training combined with vitamin D supplementation may enhance the amelioration of muscle atrophy remain incompletely elucidated. Therefore, this article systematically reviews the literature on the effects of exercise training combined with vitamin D supplementation on muscle atrophy, particularly focusing on the elderly and patients with type 2 diabetes. This review aims to summarize the progress of research in this area and provide a reference for future studies.

Classicality of the heat produced by quantum measurements

description: Quantum measurement is ultimately a physical process, resulting from an interaction between the measured system and a measuring apparatus. Considering the physical process of measurement within a thermodynamic context naturally raises the following question: How can the work and heat be interpreted? In the present paper we model the measurement process for an arbitrary discrete observable as a measurement scheme. Here the system to be measured is first unitarily coupled with an apparatus and subsequently the compound system is objectified with respect to a pointer observable, thus producing definite measurement outcomes. The work can therefore be interpreted as the change in internal energy of the compound system due to the unitary coupling. By the first law of thermodynamics, the heat is the subsequent change in internal energy of this compound due to pointer objectification. We argue that the apparatus serves as a stable record for the measurement outcomes only if the pointer observable commutes with the Hamiltonian and show that such commutativity implies that the uncertainty of heat will necessarily be classical.

description: We propose a new detection technique in the plane based on an isotropic wavelet family. This family is naturally constructed as an extension of the Gaussian-Mexican Hat Wavelet pair and for that reason we call it the Mexican Hat Wavelet Family (MHWF). We show the performance of these wavelets when dealing with the detection of extragalactic point sources in cosmic microwave background (CMB) maps: a very important issue within the most general problem of the component separation of the microwave sky. Specifically, flat two-dimensional simulations of the microwave sky comprising all astrophysical components plus instrumental noise have been analyzed for the channels at 30, 44 and 70 GHz of the forthcoming ESA's Planck mission Low Frequency Instrument (LFI). We adopt up-to-date cosmological evolution models of extragalactic sources able to fit well the new data on high-frequency radio surveys and we discuss our current results on point source detection by comparing them with those obtained using the Mexican Hat Wavelet (MHW) technique, which has been already proven a suitable tool for detecting point sources. By assuming a 5% reliability level, the first new members of the MHWF, at their ``optimal scale'', provide three point source catalogues on half of the sky (at galactic latitude |b|> 30) at 30, 44 and 70 GHz of 639, 387 and 340 extragalactic sources, respectively. The corresponding flux detection limits are 0.38, 0.45 and 0.47 Jy . By using the same simulated sky patches and at the same frequencies as before, the MHW at its optimal scale provides 543, 322 and 311 sources with flux detection limits of 0.44, 0.51 and 0.50 Jy, respectively (5% reliability level). These results show a clear improvement when we use the new members of the MHWF and, in particular, the MHW2 with respect to the MHW.

description: For a graph $G$, its Tutte symmetric function $XB_G$ generalizes both the Tutte polynomial $T_G$ and the chromatic symmetric function $X_G$. We may also consider $XB$ as a map from the $t$-extended Hopf algebra $\mathbb{G}[t]$ of labelled graphs to symmetric functions. We show that the kernel of $XB$ is generated by vertex-relabellings and a finite set of modular relations, in the same style as a recent analogous result by Penaguiao on the chromatic symmetric function $X$. In particular, we find one such relation that generalizes the well-known triangular modular relation of Orellana and Scott, and build upon this to give a modular relation of the Tutte symmetric function for any two-edge-connected graph that generalizes the $n$-cycle relation of Dahlberg and van Willigenburg. Additionally, we give a structural characterization of all local modular relations of the chromatic and Tutte symmetric functions, and prove that there is no single local modification that preserves either function on simple graphs. We also give an expansion relating $XB_G$ to $X_{G/S}$ as $S$ ranges over all subsets of $E(G)$, use this to extend results on the chromatic symmetric function to the Tutte symmetric function, and show that analogous formulas hold for a Tutte quasisymmetric function on digraphs.
