description: Gamma radiation has been shown to have demonstrable effects on some proteins of animal serum. A detailed knowledge of these alterations may contributed to an understanding of post radiation syndrome.The effect of single as well as periodic whole body irradiation on serum proteins as determined by a reliable and reproducible electrophoretic technique have apparently never been investigated. In fact, the effect of ionizing radiation on serum proteins has been little studied.

description: Background: Workplace step count challenges show promise for increasing walking and overall physical activity (PA). Both PA and walking are linked to many positive physical, mental and social health benefits but few studies have investigated the effects of interventions on work-related outcomes. Purpose: The aim of this study was to; 1) describe the process of collecting work-related outcomes as part of a real-world workplace intervention called the Step Count Challenge (SCC), and; 2) report on step counts and work-related outcomes (productivity, perceived stress and work engagement). Methods: This observational study was conducted as part of a four-week national SCC targeting employee from multiple workplaces in Scotland, UK. Participants completed an online survey and reported steps, productivity (HWQ), perceived stress (Cohen Perceived Stress Scale) and work engagement (UWES) on the week prior to the intervention starting (baseline), week 1 and week 4. Process data such as recruitment and retention rates were monitored throughout. Results: Baseline data were reported for 246 participants (mean age 42.5 yrs., 83% female). Preliminary data indicate positive changes in step counts (3558 steps/day by week 4), stress and productivity. However, process data show low uptake to the study (16% of intervention participants) and high drop out across surveys. Conclusion: The findings highlight challenges with conducting research within real-world interventions. The SCC may have a positive change on steps and some work-related outcomes such as stress and productivity. Further investigation into how robust research methods can be delivered without influencing real-world interventions is warranted.

description: In India, there have been controversies surrounding inclusiveness of contract farming arrangements (CFAs). The present paper contributes to the literature on the adoption of CFAs based on the field evidence of white onion and chipgrade potato cultivation in the selected provinces of Western India. Using the cross-sectional research design, primary data was collected from 378 randomly selected farm households using structured schedules along with the discussions with key informants. Descriptive statistics and logit regression results indicate that CFAs were inclusive, as less experienced farmers and farmers with low agricultural asset resource base preferred to cultivate under contract. However, it was found that the wealthier and more experienced farmers were the first ones to join CFAs. Survey results showed that it is generally the farmers who self-select themselves in CFAs. The participation and non-participation in CFAs is not a permanent feature. Farmers decision to contract in the forthcoming season is based on a number of factors viz. agro-climatic conditions, financial position, farmers expectation of returns in the contract and alternatives, theirs and co-farmers past experience. Imperfections in the input and output agricultural markets are the other reasons why farmers feel the need for the CFAs to grow the contract crop. Acknowledgement : This paper is a part of Ph.

description: Examination of the private economics of soil conservation is particularly germane at this time of policy reassessment under the provisions of the Soil and Water Resources Conservation Act of 1977. An understanding of farmers' perceptions of their economic interests is essential in the development of policy instruments that will achieve social objectives. We classify the evidence on the farmer's perspective into (a) what farmers say about soil conservation as indicated in surveys of opinion, (b) the record of what they are doing, and (c) the results of models which purport to show what farmers are, should be, or are going to do. A final section of the paper deals with modeling needs.

description: We study the first occurrences of gaps between primes in the arithmetic progression (P): $r$, $r+q$, $r+2q$, $r+3q,\ldots,$ where $q$ and $r$ are coprime integers, $q>r\ge1$. The growth trend and distribution of the first-occurrence gap sizes are similar to those of maximal gaps between primes in (P). The histograms of first-occurrence gap sizes, after appropriate rescaling, are well approximated by the Gumbel extreme value distribution. Computations suggest that first-occurrence gaps are much more numerous than maximal gaps: there are $O(\log^2 x)$ first-occurrence gaps between primes in (P) below $x$, while the number of maximal gaps is only $O(\log x)$. We explore the connection between the asymptotic density of gaps of a given size and the corresponding generalization of Brun's constant. For the first occurrence of gap $d$ in (P), we expect the end-of-gap prime $p\asymp\sqrt{d}\exp(\sqrt{d/φ(q)})$ infinitely often. Finally, we study the gap size as a function of its index in the sequence of first-occurrence gaps.

description: Objectives: The purpose of this study was to critically examine the qualitative research on experiences of leisure time physical activity (LTPA) for individuals with spinal cord injury (SCI). Meta-study methodology was used as a diagnostic tool to assess the theory, methods and findings of the current literature contributing to the literature by considering both the process and product of this body of research. This meta-study therefore provides a fresh perspective on research in this field. Methods: A comprehensive search of 6 sport and exercise electronic databases and manual journal searches yielded an initial total of 675 peer reviewed articles once duplicates were removed, reduced to 57 papers read in full after analysis of titles and key words. Of these 57 papers, 25 papers were identified as suitable for full based on the inclusion criteria. Studies were reviewed using meta-study methods, comprising analysis of theoretical perspectives, methodologies and findings. Results: Research guided by occupational theory is common in this field, and has contributed by identification of numerous barriers, benefits and facilitators of LTPA for individuals with SCI. More recently, narrative inquiry has revealed health narratives that are associated with SCI, narratives existing in the LTPA environment (chaos, restitution and quest) and exercise narratives restitution, exercise is medicine and exercise is progressive redemption. Conclusion: Theoretical and methodological opportunities were identified for future research that suggest a need for greater attention to be paid to the structural and contextual conditions that shape and influence the physical activity experience.

Fermi-surface topology and renormalization of bare ellipticity in an interacting anisotropic electron gas

description: We investigate effects of electron-electron interactions on the shape of the Fermi surface in an anisotropic two-dimensional electron gas using the `RPA-GW' self-energy approximation. We find that the interacting Fermi surface deviates from an ellipse, but not in an arbitrary way. The interacting Fermi surface has only two qualitatively distinct shapes for most values of $r_s$. The Fermi surface undergoes two distinct transitions between these two shapes as $r_s$ increases. For larger $r_s$, the degree of the deviation from an ellipse rapidly increases, but, in general, our theory provides a justification for the widely used elliptical Fermi surface approximation even for the interacting system since the non-elliptic corrections are quantitatively rather small except for very large $r_s$.

description: Background: Habitual physical activity (hPA) reduces cardiovascular disease (CVD) risk. Carotid-femoral Pulse Wave Velocity (cfPWV) is indicative of CVD risk, however the precise association between hPA and cfPWV is unclear and warrants further investigation. Purpose: To understand the association between hPA and cfPWV in an ostensibly healthy adult population. Methods: Searches were performed in Medline, Web of Science, SPORTDiscus and CINAHL databases to identify observational studies assessing hPA and cfPWV published up to 22/02/2021. All articles were included in the narrative synthesis and vote count analyses. Articles were included in pooled analyses where a standardised association statistic for continuous hPA and cfPWV were reported. Results: Twenty six articles were included detailing 72 analyses. Overall in 47% of analyses a significant negative association was observed between hPA and cfPWV, with no association observed in 53%. Sixteen articles provided sufficient data for meta-analysis, which demonstrated a small, significant, negative correlation between hPA and cfPWV CC= -0.09 (95%CI -0.18, -0.01); P=0.03. Heterogeneity was high at I2=95.10% P<0.001. Sub-group analyses did not change overall findings, however heterogeneity was low, effect size was smaller and 95%CI narrower in articles with device based measurement of hPA and those of a good/fair quality rating. Conclusion: There is a significant negative association between hPA and cfPWV. However, the variation in PA metrics reported and the high heterogeneity within pooled analyses, suggests that findings should be interpreted with a degree of caution. The ability to precisely quantify day-to-day movement behaviours should support future high quality research in this field.

description: We present measurements of the energy loss of pions and electrons in drift chambers operated with a Xe,CO2(15%) mixture. The measurements are carried out for particle momenta from 1 to 6 GeV/c using prototype drift chambers for the ALICE TRD. Microscopic calculations are performed using input parameters calculated with GEANT3. These calculations reproduce well the measured average and most probable values for pions, but a higher Fermi plateau is required in order to reproduce our electron data. The widths of the measured distributions are smaller for data compared to the calculations. The electron/pion identification performance using the energy loss is also presented.

description: Background: Reduced muscular strength has been associated with an increased risk of some site-specific cancers. However, there is a lack of evidence on whether grip strength expressed in absolute or relative terms could predict cancer risk differently. Purpose: Therefore, this study aimed to evaluate the association between absolute and relative grip strength with all-cause and 15 site-specific cancers. Methods: This is a prospective cohort study using data from the UK Biobank. There were 445,552 participants (53.8% women; mean age 56.3) across the UK. The exposure variable was grip strength, in absolute form (kg) and relative to weight, body mass index (BMI), height and body fat mass (BFM), the outcome was incident cancer (fatal and non-fatal). Cox proportional hazard and 95% confidence intervals (CIs). Results: During an 8.8-year follow-up period, 48,886 patients were diagnosed with cancer and 11,560 died from it. Absolute grip strength was inversely associated with five cancer sites including endometrium (HR: 0.74, 95% CI: 0.69; 0.79), gallbladder (HR: 0.81, 95% CI: 0.72; 0.92), liver (HR: 0.86, 95% CI: 0.79; 0.93), kidney (HR: 0.93, 95% CI: 0.88; 0.99), breast cancer (HR: 0.93, 95% CI: 0.91; 0.96), and all-cause cancer (HR: 0.97, 95% CI: 0.95; 0.98). Similar risk estimate for these cancers were observed when grip strength was expressed in relation to body weight, BMI and body fat but not when was expressed relative to height (Figure 1). Conclusions: Absolute grip provide similar risk estimate to those observed for relative grip strength using body weight, BMI and body fat, but not height.

description: We present a novel classification-based algorithm called GeneClass for learning to predict gene regulatory response. Our approach is motivated by the hypothesis that in simple organisms such as Saccharomyces cerevisiae, we can learn a decision rule for predicting whether a gene is up- or down-regulated in a particular experiment based on (1) the presence of binding site subsequences (``motifs'') in the gene's regulatory region and (2) the expression levels of regulators such as transcription factors in the experiment (``parents''). Thus our learning task integrates two qualitatively different data sources: genome-wide cDNA microarray data across multiple perturbation and mutant experiments along with motif profile data from regulatory sequences. Rather than focusing on the regression task of predicting real-valued gene expression measurements, GeneClass performs the classification task of predicting +1 and -1 labels, corresponding to up- and down-regulation beyond the levels of biological and measurement noise in microarray measurements. GeneClass uses the Adaboost learning algorithm with a margin-based generalization of decision trees called alternating decision trees. In computational experiments based on the Gasch S. cerevisiae dataset, we show that the GeneClass method predicts up- and down-regulation on held-out experiments with high accuracy. We explore a range of experimental setups related to environmental stress response, and we retrieve important regulators, binding site motifs, and relationships between regulators and binding sites that are known to be associated to specific stress response pathways. Our method thus provides predictive hypotheses, suggests biological experiments, and provides interpretable insight into the structure of genetic regulatory networks.

description: High-fidelity Bragg pulses are an indispensable tool for state-of-the-art atom interferometry experiments. In this paper, we introduce an analytic theory for such pulses. Our theory is based on the pivotal insight that the physics of Bragg pulses can be accurately described by the adiabatic theorem. We show that efficient Bragg diffraction is possible with any smooth and adiabatic pulse shape and that high-fidelity Gaussian pulses are exclusively adiabatic. Our results give strong evidence that adiabaticity according to the adiabatic theorem is a necessary requirement for high-performance Bragg pulses. Our model provides an intuitive understanding of the Bragg condition, also referred to as the condition on the "pulse area". It includes corrections to the adiabatic evolution due to Landau-Zener processes as well as the effects of a finite atomic velocity distribution. We verify our model by comparing it to an exact numerical integration of the Schrödinger equation for Gaussian pulses diffracting four, six, eight and ten photon recoils. Our formalism provides an analytic framework to study systematic effects as well as limitations to the accuracy of atom interferometers employing Bragg optics that arise due to the diffraction process.

In particular, we found a modest population of RR Lyrae stars tracing the presence of an old stellar component in NGC6822. Measurements of the average luminosity of RR Lyrae stars provide a new independent estimate of the distance to this galaxy based on a Pop.II indicator, (m-M)o=23.36 +/-0.17. In addition, our new data show a significant population of small-amplitude, short-period variable stars filling the instability strip starting at luminosities only a few tenths of a magnitude brighter than the RR Lyrae stars.

description: Eleodes suturalis (Say, 1823)
(Fig. 25, Map 10)
 Diagnosis. Very large, elongate, elytral dorsum flattened and slightly concave, frequently reddish along the suture. Sides of the elytra have an acute, slightly reflexed margin with the surface sulcate. Pronotum deeply concave anteriorly, widest at the middle, lateral margins dilated and reflexed. Profemora are dentate in both sexes. Length: 21–35 mm.
 Distribution. Widely distributed in Texas, Eleodes texanus Horn is a synonym of this species. The types of the latter were collected by LeConte at the ‘‘Ringold Barracks’’ which still exist at Rio Grande City. It is also found in the Great Basin states from North Dakota to Arizona. There are no records for Canada and Mexico. It is one of the false wireworms that are pests because the larvae feed on germinating wheat seeds (Calkins and Kirk 1973).

description: We develop an exact framework to describe the non-Markovian dynamics of an open quantum system interacting with an environment modeled by a generalized spectral density function. The approach relies on mapping the initial system onto an auxiliary configuration, comprising the original open system coupled to a small number of discrete modes, which in turn are each coupled to an independent Markovian reservoir. Based on the connection between the discrete modes and the poles of the spectral density function, we show how expanding the system using the discrete modes allows for the full inclusion non-Markovian effects within an enlarged open system whose dynamics is governed by an exact Lindblad master equation. Initially we apply this result to obtain a generalization of the pseudomode method [B. M. Garraway, Phys. Rev. A 55, 2290 (1997)] in cases where the spectral density function has a Lorentzian structure. For many other types of spectral density function, we extend our proof to show that an open system dynamics may be modeled physically using discrete modes which admit a non-Hermitian coupling to the system, and for such cases determine the equivalent master equation to no longer be of Lindblad form. For applications involving two discrete modes, we demonstrate how to convert between pathological and Lindblad forms of the master equation using the techniques of the pseudomode method.

description: Background: Older people have more leisure time, but many are physically inactive. Momentary feelings of pleasure or happiness and sense of purpose can be sources of intrinsic motivation. This study’s objective was to investigate how the type (sedentary, active) and context (social and environmental) of older peoples’ activities relate to momentary feelings of happiness and purpose to inform intervention and policy design. Methods: Details of activities, contexts and feelings of semi-retired adults (n=67, aged 50-78y) were captured over 7 days using ecological momentary assessment (EMA) via a smart phone app. Participants were prompted six times at random per day resulting in 2,065 valid prompts. Participants wore an Actigraph accelerometer on the waist for 7 days to measure physical activity. Happiness and sense of purpose outcome variables were regressed on EMA- identified activities, context and confounding variables. Results: Sedentary activities were negatively associated with sense of purpose, especially when indoors; however, social sedentary activities (e.g. visiting friends and family) were positively associated with feelings of happiness. Active, social outdoor activities were positively associated with both happiness and sense of purpose. Less sedentary adults were more likely to experience higher happiness and sense of purpose during all activities. Conclusions: Both happiness and sense of purpose could be leveraged to design more effective interventions and policy for older people. Context is important for happiness, and social and outdoor activities are likely to have the widest appeal. The study needs to be replicated in a larger and more representative samples of older people. Funding: None.

description: We present a detailed analytical study of the propagation of ultra high energy (UHE) particles in extragalactic magnetic fields. The crucial parameter which affects the diffuse spectrum is the separation between sources. In the case of a uniform distribution of sources with a separation between them much smaller than all characteristic propagation lengths, the diffuse spectrum of UHE particles has a {\em universal} form, independent of the mode of propagation. This statement has a status of theorem. The proof is obtained using the particle number conservation during propagation, and also using the kinetic equation for the propagation of UHE particles. This theorem can be also proved with the help of the diffusion equation. In particular, it is shown numerically, how the diffuse fluxes converge to this universal spectrum, when the separation between sources diminishes. We study also the analytic solution of the diffusion equation in weak and strong magnetic fields with energy losses taken into account. In the case of strong magnetic fields and for a separation between sources large enough, the GZK cutoff can practically disappear, as it has been found early in numerical simulations. In practice, however, the source luminosities required are too large for this possibility.

description: Many recent breakthroughs in deep learning were achieved by training increasingly larger models on massive datasets. However, training such models can be prohibitively expensive. For instance, the cluster used to train GPT-3 costs over \$250 million. As a result, most researchers cannot afford to train state of the art models and contribute to their development. Hypothetically, a researcher could crowdsource the training of large neural networks with thousands of regular PCs provided by volunteers. The raw computing power of a hundred thousand \$2500 desktops dwarfs that of a \$250M server pod, but one cannot utilize that power efficiently with conventional distributed training methods. In this work, we propose Learning@home: a novel neural network training paradigm designed to handle large amounts of poorly connected participants. We analyze the performance, reliability, and architectural constraints of this paradigm and compare it against existing distributed training techniques.

description: Developmental machine learning studies how artificial agents can model the way children learn open-ended repertoires of skills. Such agents need to create and represent goals, select which ones to pursue and learn to achieve them. Recent approaches have considered goal spaces that were either fixed and hand-defined or learned using generative models of states. This limited agents to sample goals within the distribution of known effects. We argue that the ability to imagine out-of-distribution goals is key to enable creative discoveries and open-ended learning. Children do so by leveraging the compositionality of language as a tool to imagine descriptions of outcomes they never experienced before, targeting them as goals during play. We introduce IMAGINE, an intrinsically motivated deep reinforcement learning architecture that models this ability. Such imaginative agents, like children, benefit from the guidance of a social peer who provides language descriptions. To take advantage of goal imagination, agents must be able to leverage these descriptions to interpret their imagined out-of-distribution goals. This generalization is made possible by modularity: a decomposition between learned goal-achievement reward function and policy relying on deep sets, gated attention and object-centered representations. We introduce the Playground environment and study how this form of goal imagination improves generalization and exploration over agents lacking this capacity. In addition, we identify the properties of goal imagination that enable these results and study the impacts of modularity and social interactions.

description: The impending expiration of the Food and Agriculture Act of 1977 in September 1981, provides a forum for debate regarding the operation and funding of the Food Stamp Program. In the past, a frequent proposal considered in Congress has been the adoption of a categorical or block grant approach to food awsistance programs. This report provides an analysis of changes in benefits and participation under conversion to State administration of a federally funded food stamp program.

description: We investigate the luminous X-ray sources in the Lockman Hole (LH) and the Extended Groth Strip (EGS) detected at 24microns using MIPS and also with IRAC on board Spitzer. We assemble optical/infrared spectral energy distributions (SEDs) for 45 X-ray/24micron sources in the EGS and LH. Only about 1/4 of the hard X-ray/24micron sources show pure type 1 AGN SEDs. More than half of the X-ray/24micron sources have stellar-emission-dominated or obscured SEDs, similar to those of local type 2 AGN and spiral/starburst galaxies. One-third of the sources detected in hard X-rays do not have a 24micron counterpart. Two such sources in the LH have SEDs resembling those of S0/elliptical galaxies. The broad variety of SEDs in the optical-to-Spitzer bands of X-ray selected AGN means that AGN selected according to the behavior in the optical/infrared will have to be supplemented by other kinds of data (e.g., X-ray) to produce unbiased samples of AGN.

description: Background: In Germany, National Recommendations for Physical Activity (PA) and PA Promotion are available since 2016, but their implementation at the local level remains a challenge. The project KOMBINE (Community-based PA promotion to implement the National Recommendations) aims to address this challenge with a focus on health equity. Program Delivery: KOMBINE is based on a transdisciplinary approach and the multi-level model of health promotion. Phase 1 consists of a systematic activation of stakeholders from policy, practice, and research to co-produce an action-oriented framework for community-based PA promotion focusing on health equity. In Phase 2 the framework is implemented in six communities (rural, urban, metropolis) with different levels of community readiness and socioeconomic deprivation. Building on the experiences of phase 2, a KOMBINE-manual is developed in phase 3. Evaluation: A participatory case study design is used with an evaluation of input (e.g., contextual conditions), process (e.g., structural change and development of measures), output (e.g., developed measures and their implementation), outcome (e.g., effects on the individual and population level), and impact (e.g., effects on the structural level). Conclusion: KOMBINE contributes to a deeper understanding of the implementation of National PA recommendations at the local level in Germany and the establishment of structures for sustainable PA promotion with a focus on health equity. Funding: Federal Centre for Health Education (BZgA) on behalf of and with funds from the statutory health insurances in accordance with Para.20a.SGB V within the GKV Alliance for Health (Number: Z2/1.01G/18).
