description: Background: There is an urgent need to implement effective population-wide interventions which overcome barriers to health-enhancing physical activity for children and adolescents. Policy components: The universal Active Kids voucher program led by the New South Wales (NSW) Government, Australia aims to reduce the cost of registration in structured physical activity programs for all school-enrolled children and adolescents. Evaluation: We used a prospective cohort study, to monitor physical activity and relevant outcomes in 4.5-18-year olds who used an Active Kids voucher. Generalized linear mixed models were used to examine changes from registration to after voucher use at ≤8 weeks, 9-26 weeks and ≥ 6 months. Fifty-three percent (n=671,375) of school-enrolled children in NSW registered in the program during 2018. Cohort participants (n=37,626) were followed up by-proxy using online surveys. After using a voucher, the number of days/week achieving physical activity guidelines increased significantly from 4.0 days/week (95%CI 3.8, 4.2) at registration to 4.9 days/week (95%CI 4.7, 5.1) after 6-months. Increased physical activity was observed across sociodemographic population sub-groups. The voucher-specific activity contributed 42.4% (95%CI 39.3, 45.5) to the total time children participated in structured physical activities outside of school. Children and adolescents who increased to, or maintained, high levels of activity were had social supports for being active, had active parent/caregivers and were happier than their low-active counterparts. Results: In girls, none of the variables included in the model were significantly related to zMR (p>0.05); however, in boys a negative and significant effect of MVPA was observed (b = −0.026; p = 0.011), where those who spent more time in MVPA had a better zMR profile, but no significant effect was observed for LPA or sedentariness. Conclusions: The Active Kids program shows promise as a scaled-up intervention to increase children and adolescents’ physical activity participation. Funding: NSW Government, Office of Sport.

description: Background: Perceived physical competence (PPC) promote physical activity (PA), but the relationship between PPC and the type of PA was not clear. Purpose: To investigate the relationship between PPC and outdoor play (OP) among school-aged children and to identify any sex-specific differences. Methods: Total 288 children (134 girls; mean age 10.6 years) from two elementary schools in Japan were included. OP and PPC were assessed using self-report questionnaires. The children described the time of OP on each weekday and were categorized as “High” if they performed OP for ≥1 h at least three times a week. The questionnaire of PPC comprised 12 questions scored on a five-point scale. Higher scores indicated better PPC, and the summed score was used. Logistic regression analyses were performed after adjusting for age, sex, body mass index, screen time, sports club participation, and the number of friends. Results: Children with higher scores of PPC had a significantly higher probability of being categorized as “High” [crude OR: 1.04; 95% CI: 1.00–1.08, adjusted OR: 1.04; 95% CI: 1.00–1.08]. In stratified analysis by sex, girls with higher scores of PPC had a significantly higher probability of being categorized as “High” [crude OR: 1.08; 95% CI: 1.01–1.15, adjusted OR 1.09; 95% CI: 1.02–1.17]. There was no association between PPC and OP among boys. Conclusion: Especially for girls, improving PPC may promote OP as a voluntary PA. Funding: This research did not receive any specific grant.

description: We analyze the interaction-induced renormalization of single-particle excitations in the two-dimensional Hubbard model at weak coupling using the Wick-ordered version of the functional renormalization group. The self energy is computed for real frequencies by integrating a flow equation with renormalized two-particle interactions. In the vicinity of hot spots, that is points where the Fermi surface intersects the umklapp surface, self energy effects beyond the usual quasi-particle renormalizations and damping occur near instabilities of the normal, metallic phase. Strongly enhanced renormalized interactions between particles at different hot spots generate a pronounced low-energy peak in the imaginary part of the self energy, leading to a pseudogap-like double-peak structure in the spectral function for single-particle excitations.

description: Background: Outdoor play in childhood is important for physical, cognitive, and social development. Outdoor play is thought to be influenced by friends, but the relationship is not clear. Purpose: To investigate the association between peer group size and outdoor play among children aged 9-12 years. Methods: We recruited fourth- to sixth-grade children from two public elementary schools in Kobe, Japan. Children who participated in outdoor play on 3 or more of the 5 weekdays were categorized into “high”. We asked children to nominate up to 10 of their closest friends. And we calculated peer group size as the total number of reciprocal closest friends in each child. Multivariate logistic regression analysis was conducted to investigate the association between peer group size and outdoor play frequency, adjusted for sex, grade, school, body mass index, sports club participation, screen time of using cell phones and screen time of playing video games. Results: The analysis sample comprises 291 children (137 girls, mean age: 10.59 ± 1.02 years). For outdoor play frequency, 114 children (39%) were classified in the “high”. The mean peer group size was 3.90 ± 2.07. Children with larger peer group size had a significantly higher probability of being categorized as “high” (odds ratio: 1.23, 95% confidence interval: 1.09-1.39). Conclusion: This study suggested that encouraging children to interact with each other may promote them to participate in outdoor play. Funding: This research received no specific grant.

description: Lattice deformations act on the low-energy excitations of Dirac materials as effective axial vector fields. This allows to directly detect quantum anomalies of Dirac materials via the response to axial gauge fields. We investigate the parity anomaly in Dirac nodal line semimetals induced by lattice vibrations, and establish a topological piezoelectric effect; i.e., periodic lattice deformations generate topological Hall currents that are transverse to the deformation field. The currents induced by this piezoelectric effect are dissipationless and their magnitude is completely determined by the length of the nodal ring, leading to a semi-quantized transport coefficient. Our theoretical proposal can be experimentally realized in various nodal line semimetals, such as CaAgP and Ca$_{_3}$P${_2}$.

description: A study was undertaken to identify patterns of consumer use of outdoor wood boilers or outdoor wood furnaces (technically referred to as outdoor wood-fired hydronic heaters (OWHHs)) and indoor wood stoves (IWSs) to inform the development of performance testing protocols that reflect real-life operating conditions. These devices are manually fed, and their usage protocols are a function of a number of variables, including user habits, household characteristics, and environmental factors. In this study, researchers logged the stack wall temperatures of 4 OWHH and 20 IWS units in the states of New York and Washington over two heating seasons. Stack wall temperature is an indicator of changes in combustion modes. Two algorithms were developed to identify usage modes and cold and warm start refueling events from the stack wall temperature time series. A linear correlation analysis was conducted to evaluate the effect of heat demand on usage patterns. The results and methods presented here will inform the cataloging of typical operational patterns of OWHHs and IWSs as a step in the development of performance testing procedures that represent actual in-home usage patterns. Implications: Current US regulatory programs for residential wood heating use a certification program to assess emissions and efficiency performance. Testing under this program uses a test that burns 100% of a single, standardized wood fuel charge to assess performance at different steady-state load conditions. This study assessed in-field operational patterns to determine if the current certification approach accurately characterized typical homeowner use patterns. The data from this study can be used to inform revisions to testing methods to increase certification test comparability between lab and field performance.

description: In this investigation optical interactions between electronic-vibrational states of the diatomic N(,2) molecule are studied. As a system of interactions, nitrogen leads to a broader understanding of cascade systems in general. Laser oscillation in N(,2) occurs quite readily in electrical discharges on an ultraviolet and a near infrared system of emission bands, among others. While the mechanisms that produce population inversions for the uv oscillations have previously been established for the most part, the dominant mechanisms for the ir bands were not at all certain. This work sought specific information about N(,2) as a lasing material and clarified that the ir-laser transitions are excited partly through a cascade involving uv-laser transitions. A concise theory of cascade interactions and excitations was developed to predict both spontaneous and stimulated emission strengths. A more sophisticated theory which took the electron-energy distribution of the laser's excitation into account was used to predict spectra. An important outcome of this theoretical and experimental investigation is how well the spectral measurements bear out the theory. The typical 3-level rate-equation theory was extended for a pulsed laser application to a 4-level system including cascade. This research concluded that the Franck-Condon Principle can be a powerful quantitative tool (not simply qualitative) to use in analyzing interactions.

Assuming that $κ\in (0;1/43)$, we show that low-energy states of the system exhibit complete Bose-Einstein condensation by providing explicit bounds on the expectation and on higher moments of the number of excitations.

description: Background: With the economic and social change, participation in occupational and transport-related physical activity is declining among Nepalese adults, highlighting the growing importance of leisure-time physical activity (LTPA). Purpose: To qualitatively explore the socioecological influences upon participation in LTPA among Nepalese adults aged 40 years and above. Methods: A total of 51 adults (30 females and 21 males) participated in one of nine focus groups conducted in Kathmandu, Nepal. Data collection was guided by the social-ecological model of physical activity and analysis was done using the reflexive thematic analysis approach in NVivo 12. Results: Leisure time was mostly spent resting, socialising, or engaging in sedentary activities such as watching television. Individual-level barriers to LTPA participation included lack of knowledge, perceived lack of skill, lack of motivation, considering oneself as sufficiently active and engagement in sedentary screen activities. Family and household responsibilities, lack of support and fear of being judged by community members constituted the interpersonal barriers, while environmental barriers to LTPA included an absence of a supportive social norm, lack of open spaces, weather conditions and perceived lack of safety. Health benefits, prioritising physical activity, social support, provision of group-based activities and age-appropriate public exercise facilities were identified as major facilitators. Conclusion: Critical issues that need to be addressed to increase LTPA among Nepalese adults include traditional gender roles, family and social support, and social norms. Modifications of the built environment, such as public exercise facilities, offer further opportunities and will require coordination beyond the health sector.

description: We propose a scheme for the generation of hybrid states entangling a single-photon time-bin qubit with a coherent-state qubit encoded on phases. Compared to other reported solutions, time-bin encoding makes hybrid entanglement particularly well adapted to applications involving long-distance propagation in optical fibers. This makes our proposal a promising resource for future out-of-the-laboratory quantum communication. In this perspective, we analyze our scheme by taking into account realistic experimental resources and discuss the impact of their imperfections on the quality of the obtained hybrid state.

description: Following rapid expansion of U.S. agricultural exports to Eastern Europe during the seventies, the prospects for continued growth of these exports are examined for the coming 5 years. Because of their overriding share of U.S. agricultural exports to the region, analysis is limited to grains, oilseeds, and oilseed meal. Results indicate a stagnation in U.S. agricultural exports, due to a decline in East European grain imports from their 1979/80 peak.

description: A quantum mechanical analysis of the Josephson phase escape in the presence of both dc and ac bias currents is presented. We find that the potential barrier for the escape of the phase is effectively suppressed as the resonant condition occurs, i.e. when the frequency $ω$ of the ac bias matches the Josephson junction energy level separation. This effect manifests itself by a pronounced drop in the dependence of the switching current $I_s$ on the power $W$ of the applied microwave radiation and by a peculiar double-peak structure in the switching current distribution $P(I_s)$. The developed theory is in a good accord with an experiment which we also report in this paper. The obtained features can be used to characterize certain aspects of the quantum-mechanical behavior of the Josephson phase, such as the energy level quantization, the Rabi frequency of coherent oscillations and the effect of damping.

description: We develop a stochastic description of the topological properties in an interacting Chern insulator. We confirm the Mott transition's first-order nature in the interacting Haldane model on the honeycomb geometry, from a mean-field variational approach, supported by density matrix renormalization group results and Ginzburg-Landau arguments. From the Bloch sphere, we make predictions for circular dichroism of light related to the quantum Hall conductivity on the lattice and in the presence of interactions. This analysis shows that the topological number can be measured from the light response at the Dirac points. Electron-electron interactions can also produce a substantial number of particle-hole pairs above the band gap, which leads us to propose a "stochastic Chern number" as an interacting measure of the topology. The stochastic Chern number can describe disordered situations with a fluctuating staggered potential and we build an analogy between interaction-induced particle-hole pairs and temperature effects. Our stochastic approach is physically intuitive, easy to implement and leads the way to further studies of interaction effects.

description: Purpose: To investigate the variability of daily patterns of park use (PU), leisure-time physical activity (LTPA) and psychological stress; relationships of PU and LTPA with stress; and, whether these relationships are independent. Methods: Singapore citizens/permanent residents 21-75 years-of-age from the Multi-Ethnic Cohort were enrolled into this study. Participants received mobile-Ecological Momentary Assessment (m-EMA) mini-surveys for up to nine days via their smartphone, including questions on PU and LTPA that day, plus perceived stress level that evening. Descriptive statistics summarized participant demographics, day-to-day variation in PU, LTPA and stress. Logistic regression models using generalized estimating equations assessed relationships of PU and LTPA with stress. Interaction effects between PU and LTPA were assessed. Results: From 709 participants, 85.2% (n=605, 4,678 m-EMA responses) were included in analyses - mean age 45.1 years; 53.9% female; 71.9% Chinese. Proportions reporting any stress were highest (39.5%) on Mondays and lowest on Sundays (29.2%), whilst PU and LTPA participation respectively were lowest (22.8%, 30.4%) on Mondays and highest on Saturdays/Sundays (26.5%, 39.2%). PU and LTPA participation (vs. no PU and no LTPA) were both associated with lower evening stress (respectively, Adjusted Odds Ratio (AOR)=0.67; 95% CI=0.58–0.77; AOR=0.73; 95% CI=0.64–0.82). Associations were independent (interaction term between PU and LTPA: p=0.99). Conclusions: Daily PU and LTPA were both associated with reduced evening stress. These associations were independent from each other, suggesting both contribute to reducing psychological stress amongst adults.

description: Preparing the ground state of a given Hamiltonian and estimating its ground energy are important but computationally hard tasks. However, given some additional information, these problems can be solved efficiently on a quantum computer. We assume that an initial state with non-trivial overlap with the ground state can be efficiently prepared, and the spectral gap between the ground energy and the first excited energy is bounded from below. With these assumptions we design an algorithm that prepares the ground state when an upper bound of the ground energy is known, whose runtime has a logarithmic dependence on the inverse error. When such an upper bound is not known, we propose a hybrid quantum-classical algorithm to estimate the ground energy, where the dependence of the number of queries to the initial state on the desired precision is exponentially improved compared to the current state-of-the-art algorithm proposed in [Ge et al. 2019]. These two algorithms can then be combined to prepare a ground state without knowing an upper bound of the ground energy. We also prove that our algorithms reach the complexity lower bounds by applying it to the unstructured search problem and the quantum approximate counting problem.

description: We discuss a simple model for the growth of supermassive black holes (BHs) at the center of spheroidal stellar systems. In particular, we assess the hypotheses that (1) star formation in spheroids and BH fueling are proportional to one another, and (2) the BH accretion luminosity stays near the Eddington limit during luminous quasar phases. With the aid of this simple model, we are able to interpret many properties of the QSO luminosity function, including the puzzling steep decline of the characteristic luminosity from redshift z=2 to to z=0: indeed the residual star formation in spheroidal systems is today limited to a small number of bulges, characterized by stellar velocity dispersions a factor of 2-3 smaller those of the elliptical galaxies hosting QSOs at z > 2. A simple consequence of our hypotheses is that the redshift evolution of the QSO emissivity and of the star formation history in spheroids should be roughly parallel. We find this result to be broadly consistent with our knowledge of the evolution of both the global star formation rate, and of the evolution of the QSO emissivity, but we identify interesting discrepancies at both low and high redshifts, to which we offer tentative solutions. Finally, our hypotheses allow us to present a robust method to derive the duty cycle of QSO activity, based on the observed QSO luminosity function, and on the present-day relation between the masses of supermassive BHs and those of their spheroidal host stellar systems. The duty cycle is found to be substantially less than unity, with characteristic values in the range (3-6)x10^(-3), and we compute that the average bolometric radiative efficiency is epsilon=0.07. Finally, we find that the growth in mass of individual black holes at high redshift (z>2) can be dominated by mergers, and is therefore not necessarily limited by accretion.

description: Background: The ENJOY project (Exercise interveNtion outdoor proJect in the cOmmunitY for older people) is a community research project actively promoting physical activity engagement and well-being through the delivery of an exercise program using outdoor multimodal exercise equipment (the Seniors Exercise Park https://youtu.be/PaYuCMtnlYk). Purpose: This study investigated the impact of the physical activity program, on health, physical function, and falls in older people. Method: Inactive older people (with increased falls risk) were recruited and underwent a 3-month supervised outdoors exercise program followed by 6-month maintenance phase (unstructured physical activity program). Participants’ physical activity, physical function, falls and health related quality of life were assessed at baseline, 3-months and 9-months, with an overall 12-months falls record follow up. Results: Eighty people completed the 3-month intervention, 58 completed the 9-month assessment (due to COVID-19 restrictions), with 54 available for the 12-months falls analysis. A significant improvement in physical activity, physical function (p<0.01), self-rated quality of life (p<0.05), wellbeing (p<0.01), fear of falls (p<0.01), falls risk (p<0.01), depressive symptoms (p=0.01) and loneliness (p=0.03) were reported at 3-months. The improvement in physical activity and physical function was maintained at 9 month. Number of fallers (from 51.8% to 31.4%, p=0.03) and falls incidence (from 42 to 29 falls, p<0.01) were significantly reduced at the 12-months follow up. Conclusion: The Seniors Exercise Park program offers various health and physical benefits, and can be an important public health infrastructure investment in promoting physical activity for older people.

description: A longstanding public interest in the economics of the dairy industry has fostered major research efforts on the local, State, regional, and national levels. Due to the large numbers of publications stemming from the above research efforts, several bibliographies covering the literature have appeared. This bibliography builds on those previous undertakings, but primarily deals with studies concerning public policy issues of the seventies and early eighties. One central topic of research in this area has been the high level of government intervention in the production and distribution of milk and milk products.

description: Nap pods within the university environment are becoming increasingly popular with the intention of providing students an opportunity for rest. However, in order to design optimal nap pods, it is important to analyze the many factors that contribute to the design process, including light, sound, temperature, and aroma. In this study, we chose to explore the effects of lighting colour and intensity on perceptions of comfort in nap pods, with the aim of finding which lighting colours and intensities students would associate with feelings of calmness and sleepiness, and which would be associated with feelings of alertness and wakefulness. This was done through the administration of a survey in which participants rated their feelings of calmness, sleepiness, alertness, and wakefulness after seeing an image of a nap pod in different lighting colour hues and intensity. We found that overall, cool colours with a blueish hue and dim and moderate intensities of brightness were preferred by participants.

description: Let (M('n),g) be a compact connected orientable Riemannian manifold of dimension n,g the fundamental tensor. For 0 (LESSTHEQ) p (LESSTHEQ) n let (DELTA) be the Laplace-Beltrami operator on exterior p-form on M. The set.

The question of how the spectrum of M determines the structure of M has been studied by various authors. It is proved that the asymptotic expansion (the heat expansion). (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). holds, where a(,i,p) are Riemannian invariants. The coefficients a(,0,0), a(,1,0), a(,2,0) have been computed by M. Berger and by McKean and Singer. a(,1,p), a(,2,p) have been computed by V. K. Patodi, and a(,3,0) by T. Sakai.(,). In this dissertation, for various special kinds of manifolds, we write out these coefficients and the coefficients b(,i)(i=1,2,3) of. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). the power series expansion (in normal coordinates) for the volume of a small geodesic ball with center m and radius r computed by A. Gray and L.

We then compute the coefficients a(,3,p) and a(,4,p) for 2-dimensional compact Riemannian manifolds.

description: A study was undertaken to identify patterns of consumer use of outdoor wood boilers or outdoor wood furnaces (technically referred to as outdoor wood-fired hydronic heaters (OWHHs)) and indoor wood stoves (IWSs) to inform the development of performance testing protocols that reflect real-life operating conditions. These devices are manually fed, and their usage protocols are a function of a number of variables, including user habits, household characteristics, and environmental factors. In this study, researchers logged the stack wall temperatures of 4 OWHH and 20 IWS units in the states of New York and Washington over two heating seasons. Stack wall temperature is an indicator of changes in combustion modes. Two algorithms were developed to identify usage modes and cold and warm start refueling events from the stack wall temperature time series. A linear correlation analysis was conducted to evaluate the effect of heat demand on usage patterns. The results and methods presented here will inform the cataloging of typical operational patterns of OWHHs and IWSs as a step in the development of performance testing procedures that represent actual in-home usage patterns. Implications: Current US regulatory programs for residential wood heating use a certification program to assess emissions and efficiency performance. Testing under this program uses a test that burns 100% of a single, standardized wood fuel charge to assess performance at different steady-state load conditions. This study assessed in-field operational patterns to determine if the current certification approach accurately characterized typical homeowner use patterns. The data from this study can be used to inform revisions to testing methods to increase certification test comparability between lab and field performance.

description: Background: Low self-efficacy can cause physical inactivity among older people. Increasing perception of green space is one of the effective approaches to physical activity, but it is not clear among older people with low self-efficacy. Purpose: This study aims to investigate the association between walking and perception of green space among older people with low self-efficacy. Methods: We conducted a cross-sectional study among 104 community-dwelling older people with low self-efficacy (mean age = 79.7 years, 69.2 % females). Low self-efficacy was defined as below the median score on the self-efficacy for exercise scale. Walking was measured using International Physical Activity Questionnaire and “more walking” was defined as ≥150 minutes of walking per week. Perception of green space was measured by an 8-item questionnaire and “high perception of green space” was defined as above the median score. To investigate the association, unadjusted and adjusted logistic regression analysis was used and adjusted the following confounding variables: age, gender, and years of education. Results: Fifty-one participants (49.0%) were “more walking” and 48 participants (46.2%) had “high perception of green space”. Even after adjusted, people with “high perception of green space” was “more walking” (Odds ratio = 3.02, 95% Confidence interval = 1.34-7.08). Conclusion: Our findings suggest that increasing perception of green space may be important to encourage walking among older people with low self-efficacy. Funding: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.

description: ing a components-of-growth approach, this study analyzes factors affecting declining long-term rates of agricultural growth in selected countries of Latin America and Asia. In both regions, the contribution of expanding agricultural land area to crop output growth has significantly declined and the contribution of yield increase has been marginal. However, the relative importance of changes in the cropping pattern has increased moderately over the long term. Prospects for production growth will depend upon the development and adoption of yield-enhancing innovations in Latin America, and a shift to higher value cereals in Asia.
