description: Model matter agglomerations, with temperature as leading control parameter, have been considered, and some of their characteristics have been studied. The primary interest has been focused on the grain volume fluctuations, the magnitude of which readily differentiates between two commonly encountered types of matter agglomeration/aggregation processes, observed roughly for high- and low-density matter organizations. The two distinguished types of matter arrangements have been described through the (entropic) potential driving system. The impact of the potential type on the character of matter agglomeration has been studied, preferentially for (low density) matter agglomeration for which a logarithmic measure of its speed has been proposed. A common diffusion as well as mechanical relaxation picture, emerging during the mature growing stage, has been drawn using a phenomenological line of argumentation. Applications, mostly towards obtaining soft agglomerates of so-called jammed materials, have been mentioned.

description: We have performed precision laser spectroscopy on individual 6He (t1/2 = 0.8 s) atoms confined and cooled in a magneto-optical trap, and measured the isotope shift between 6He and 4He to be 43,194.772 +/- 0.056 MHz for the 2 3S1 - 3 3P2 transition. Based on this measurement and atomic theory, the nuclear charge radius of 6He is determined, for the first time in a method independent of nuclear models, to be 2.054 +/- 0.014 fm. The result is compared with the values predicted by a number of nuclear structure calculations, and tests their ability to characterize this loosely bound, halo nucleus.

description: How long antihydrogen atoms linger in the ALPHA magnetic trap is an important characteristic of the ALPHA apparatus. The initial trapping experiments in 2010 [1] were conducted with 38 detected antiatoms confined for 172 ms and in 2011 [2] with seven for 1000 s. Long confinement times are necessary to perform detailed frequency scans during spectroscopic measurements. An analysis carried out, using machine learning methods, on more than 1000 antiatoms confined for several hours in the ALPHA-2 magnetic trap, yields a preliminary lower limit to the lifetime of 66 hours. Hence this observation suggests that the measured confinement time of antihydrogen is extended by more than two orders of magnitude. [1] Andresen, G. B. et al.

description: This paper is an English perspective on the Liang study (2006) into educational contexts for schooling in science; the linkage between teachers’ understanding of the Nature of Science (NoS) and their effectiveness as educators. The work reflects on the basic training received by pre-service teachers in secondary science at the University of London (UEL), and a number of interventions introduced to enhance their awareness and discrimination of NoS. The study is a three-year longitudinal design and intended to probe trainee teachers’ perceptions of NoS. It explores how these notions may be affected by the training experienced in both the university and school placement in the context of the new Science National Curriculum for Schools (England).

description: We have analyzed a single vortex at T=0 in a 3D superfluid atomic Fermi gas across a Feshbach resonance. On the BCS side, the order parameter varies on two scales: $k_{F}^{-1}$ and the coherence length $ξ$, while only variation on the scale of $ξ$ is seen away from the BCS limit. The circulating current has a peak value $j_{max}$ which is a non-monotonic function of $1/k_F a_s$ implying a maximum critical velocity $\sim v_F$ at unitarity. The number of fermionic bound states in the core decreases as we move from the BCS to BEC regime. Remarkably, a bound state branch persists even on the BEC side reflecting the composite nature of bosonic molecules.

description: We present a search for anisotropic cosmic birefringence in 500 deg$^2$ of southern sky observed at 150 GHz with the SPTpol camera on the South Pole Telescope. We reconstruct a map of cosmic polarization rotation anisotropies using higher-order correlations between the observed cosmic microwave background (CMB) $E$ and $B$ fields. We then measure the angular power spectrum of this map, which is found to be consistent with zero. The non-detection is translated into an upper limit on the amplitude of the scale-invariant cosmic rotation power spectrum, $L(L+1)C_L^{αα}/2π< 0.10 \times 10^{-4}$ rad$^2$ (0.033 deg$^2$, 95% C.L.). This upper limit can be used to place constraints on the strength of primordial magnetic fields, $B_{1 \rm Mpc} < 17 {\rm nG} $ (95% C.L.), and on the coupling constant of the Chern-Simons electromagnetic term $g_{aγ} < 4.0 \times 10^{-2}/H_I $ (95% C.L.), where $H_I$ is the inflationary Hubble scale. For the first time, we also cross-correlate the CMB temperature fluctuations with the reconstructed rotation angle map, a signal expected to be non-vanishing in certain theoretical scenarios, and find no detectable signal. We perform a suite of systematics and consistency checks and find no evidence for contamination.

description: Human head pose estimation is an essential problem in facial analysis in recent years that has a lot of computer vision applications such as gaze estimation, virtual reality, and driver assistance. Because of the importance of the head pose estimation problem, it is necessary to design a compact model to resolve this task in order to reduce the computational cost when deploying on facial analysis-based applications such as large camera surveillance systems, AI cameras while maintaining accuracy. In this work, we propose a lightweight model that effectively addresses the head pose estimation problem. Our approach has two main steps. 1) We first train many teacher models on the synthesis dataset - 300W-LPA to get the head pose pseudo labels. 2) We design an architecture with the ResNet18 backbone and train our proposed model with the ensemble of these pseudo labels via the knowledge distillation process. To evaluate the effectiveness of our model, we use AFLW-2000 and BIWI - two real-world head pose datasets. Experimental results show that our proposed model significantly improves the accuracy in comparison with the state-of-the-art head pose estimation methods. Furthermore, our model has the real-time speed of $\sim$300 FPS when inferring on Tesla V100.

description: In the presence of an external field, the imposition of specific boundary conditions can lead to interesting new manifestations of the Casimir effect. In particular, it is shown here that even a single conducting plate may experience a non-zero force due to vacuum fluctuations. The origins of this force lie in the change induced by the external potential in the density of available quantum states.

description: Increases in petroleum prices have affected the prices of its derived products. In addition, the interest in issues related to the environment and energy security at world-wide level has been increased. All of these factors have contributed to the development of alternative fuel such as the ethanol, biodiesel and natural gas. This study analyzes the main agricultural products used to produce biodiesel, their production costs and the utilization of those inputs in other industries. This study will also include a brief summary of different legislations in those countries under analysis. On the other hand, we will find break-even points and apply a sensibility analysis associated with distinct scenarios in terms of input-output prices.

description: This paper explores how trainee teachers in physical education (PE) are supported in their use of information communication technology (ICT) during their school-based experiences. The data were collected from within the context of a higher education institution (HEI) and school partnership in the South East of England. All of the schools approached had previously worked, or were working, with trainee teachers from the University of East London (UEL). These data were initially collected by using questionnaires sent out to 100 PE teachers. Following initial analysis of these data, three semi-structured interviews were carried out with the hope of developing ICT provision within the HEI and discovering how best to support school-based mentors and trainees. There was evidence of lots of good examples of work within the partnership but little to support the fact that teachers were sharing this. It is clear that, in this particular case, the potential of the use of ICT in PE has not been unlocked by the profession as yet.

description: The profitability of a production system of oyster mushrooms was evaluated under conditions of greenhouse with a surface of 112 m2 located in San Salvador Chachapa, pertaining to the municipality of Amozoc de Mota in the state of Puebla. The indicators of economic evaluation were used: net present value (NPV), relation benefit-cost (B/C), relation net benefitinvestment (N/K) and internal rate of return (IRR) to make the yield analysis. The results obtained for a period of 5 years were: NPV = 50.098,46, B/C = 1, 04, N/K = 1.23 and IRR = 11.82. With base in these indicators, one concluded that the project is viable from the economic point of view. In accordance with analysis, profitability of project of investment is excellent and the production system of oyster mushrooms under conditions of greenhouse has good perspectives of commercialization.

We study both the special and general relativistic corrections to lasing in such dense axion clusters as they evolve in static spacetimes. Our main results are rate equations for the evolution of axion and photon number densities that include these corrections. We use Schwarzschild spacetime as a detailed example.

description: As part of a large Spitzer/MIPS GTO program, we have searched for infrared excesses due to debris disks toward 26 FGK field stars known from radial velocity (RV) studies to have one or more planets. While none of these stars show excesses at 24um, we have detected 70um excesses around 6 stars at the 3-sigma confidence level. The excesses are produced by cool material (< 100 K) located beyond 10 AU, well outside the "habitable zones" of these systems and consistent with the presence of Kuiper Belt analogues with ~100 times more emitting surface area than in our own planetary system. These planet-bearing stars are, by selection for RV studies, typically older than 1 Gyr, and the stars identified here with excesses have a median age of 4 Gyr. We find a preliminary correlation of both the frequency and the magnitude of dust emission with the presence of known planets. These are the first stars outside the solar system identified as having both well-confirmed planetary systems and well-confirmed IR excesses.

description: Extensive ejidal cattle in northern México has developed due adequate water soil and climate conditions; nevertheless, in the past few years a natural resources harm has been observed as well as a trend of emigration of the population. The methodology utilized in this paper was supported in a pool to ejidal cattle producers of the San Luis del Cordero County in the state of Durango, by means of stratified random sampling based on the number of cows. Results have shown that producers owning less than 20 cows depend mostly on remittances from emigrants. This group of producers also are less organized and with less technology for the agricultural and cattle activities. This study presents a characterization of the ejidal cattle production system identifying the main factors that limits this activity. It is concluded that the ejidal cattle located in the middle part of the Occidental Sierra Madre survive due the remittances of emigrants and that the economical growth of this people is more limited by natural causes rather than economical since the people is getting older and the forage availability is diminishing.

description: We show that six-dimensional supergravity models admit nonsingular solutions in the presence of flat three-brane sources with positive tensions. The models studied in this paper are nonlinear sigma models with the target spaces of the scalar fields being noncompact manifolds. For the particular solutions of the scalar field equations which we consider, only two brane sources are possible which are positioned at those points where the scalar field densities diverge, without creating a divergence in the Ricci scalar or the total energy. These solutions are locally invariant under 1/2 of D=6 supersymmetries, which, however, do not integrate to global Killing spinors. Other branes can be introduced by hand by allowing for local deficit angles in the transverse space without generating any kind of curvature singularities.

description: There is something about a change of UK government that often seems to trigger a bout of reforming zeal on the part of new ministers to effect perceived ‘improvements’ in the English education system. Modification – radical or otherwise – seems to be endemic, perhaps because education always has been (and probably will continue to be) a contested concept. At present (2011), there are new initiatives to effect changes across all formal education sectors, from early childhood through to higher education. Among these are two that have a particular impact on my own professional life in the worlds of music education and teacher education, namely the review of the National Curriculum (NC) and the introduction of a so-called ‘English Baccalaureate’.

description: The purpose of this research is to know the meaning, which the diverse social groups attribute to a new technology, with the assumption that for the group that work planting, the seeding device represents the accomplishment of their work with greater rapidity and exactitude, whereas for the owner it represents savings in the production process. In order to attain this goal one begins with a concept of technology, which is understood as the application of the scientific method to the procedures of manufacture and development of administrative processes in companies. In addition, one considers that the technological innovation is the creative activity that is set to create wealth and social welfare through technology. Whereas social construction of technology can be contemplated as a common frame of meaning related to a technology in particular, which is shared among several social groups and that, in addition, guides and gives form to the development of the devices. After gathering data and analyzing the answers of the users of the multiple fine grain planting machines, the social construction that took place in relation to its use could be appreciated, since there were points of converging meaning for the actors involved in the use of this technology.

description: We present a benchmark test suite and an automated machine learning procedure for evaluating supervised machine learning (ML) models for predicting properties of inorganic bulk materials. The test suite, Matbench, is a set of 13 ML tasks that range in size from 312 to 132k samples and contain data from 10 density functional theory-derived and experimental sources. Tasks include predicting optical, thermal, electronic, thermodynamic, tensile, and elastic properties given a materials composition and/or crystal structure. The reference algorithm, Automatminer, is a highly-extensible, fully-automated ML pipeline for predicting materials properties from materials primitives (such as composition and crystal structure) without user intervention or hyperparameter tuning. We test Automatminer on the Matbench test suite and compare its predictive power with state-of-the-art crystal graph neural networks and a traditional descriptor-based Random Forest model. We find Automatminer achieves the best performance on 8 of 13 tasks in the benchmark. We also show our test suite is capable of exposing predictive advantages of each algorithm - namely, that crystal graph methods appear to outperform traditional machine learning methods given ~10^4 or greater data points. The pre-processed, ready-to-use Matbench tasks and the Automatminer source code are open source and available online (http://hackingmaterials.lbl.gov/automatminer/). We encourage evaluating new materials ML algorithms on the MatBench benchmark and comparing them against the latest version of Automatminer.

description: Adolescent girls and young women (AGYW) in sub-Saharan Africa face unique barriers to contraceptive access and lack AGYW-centered contraceptive decision-support resources. To empower AGYW to make informed choices and improve reproductive health outcomes, we developed a tablet-based application to provide contraceptive education and decision-making support in the pharmacy setting - a key source of contraceptive services for AGYW - in Kenya. We conducted workshops with AGYW and pharmacy providers in Kenya to gather app feedback and understand how to integrate the intervention into the pharmacy setting. Our analysis highlights how intermediated interactions - a multiuser, cooperative effort to enable technology use and information access - could inform a successful contraceptive intervention in Kenya. The potential strengths of intermediation in our setting inform implications for technological health interventions in intermediated scenarios in \lrem{LMICs}\ladd{low- and middle-income countries}, including challenges and opportunities for extending impact to different populations and integrating technology into resource-constrained healthcare settings.

description: A comprehensive economic impact assessment using input-output methods is developed to account for localized spending activities and distributions of residual earning to member owners by cooperatives. The framework is applied to agricultural supply, service, marketing, farm credit, and rural electric cooperatives doing business in New York State. Detailed spending patterns from cooperative survey data reveal that agricultural cooperatives in the state have higher levels of localized spending when compared to average industry firms using aggregate industry data and equivalent levels of direct industry output. Accordingly, total economic impacts for these cooperatives; i.e., the direct, indirect, and induced effects, are larger. Overall, agricultural cooperatives contribute 7%, 3%, and 10% more total impact with respect to jobs, labor income, and output in New York State. Limitations to the enumeration of total impact to local economies are discussed and directions for future research that encompass more than current economic impacts are proposed

description: Mushrooms are one of the organisms the nature that have a great capacity to adapt and develop in different weather conditions and in different agricultural environments. Mushrooms also make an important contribution to the satisfaction of some human necessities by the input of nutritional and medicinal products due to a wide diversity of properties that they posses. In addition, its production generates incomes and employment, for these reasons, the farming of mushrooms is a very important activity socially, economical and ecologically. In Yucatán, the farming of the mushroom “Pleurotus ostreatus “represents an option for the sustainable development of poor rural communities. Based on the previous assumptions, the objective of the present work was to describe the consumption of mushrooms in the city of Mérida, Yucatán, México, through the perspective of two types of retailers: supermarkets and restaurants. The information could be used to facilitate successful access to the market for the mushroom producers. A cross-sectional descriptive study with a quantitative approach was done, in which the sample was formed by 15 supermarkets and 28 restaurants. The techniques of direct observation and interview were used. Based on the obtained result, which concludes that the acceptance of the mushroom “pleurotus ostreatus” is growing among the yucatecan population and represents a good option for the sustainable development of the small producers.
Place, (cyber) space and being: the role of student voice in informing the un-situated learning of trainee teachers

description: This article explores the ambiguities and ontological insecurities of pre-service trainee teachers as they prepare to enter training for work in the post-compulsory sector in the UK. Adopting a contextual sensitivity which explores the role of location in teachers’ professional learning, it makes problematic the anxieties and un-situated learning of trainees as they begin to boundary-shift professional identities at the very start of a PGCE programme. Contextualised by the hyper-rapid and intensified spatiality of teaching, learning and training in east London, the article explores the polycontexual realities of entering a newly drawn professional field in a global metropolis. Trainees’ identity formation and lived experiences are captured by means of a digital ethnographic approach. The adoption of student voice research – as a teaching and reflection tool – is tempered against trainee teachers’ own uncertain, (re)forming and emerging reflective voices captured through an ethnographic sensibility.

description: This article aims to consider the relative virtues of ICT and/or computing in schools, and present the findings from some research conducted in April/May 2011, with Postgraduate Certificate of Education (PGCE) and Graduate Teacher Programme (GTP) ICT students and ICT teacher colleagues in a sample of the University of East London’s partner secondary schools (educating children from the ages of 11 to 16 and, if a sixth form exists, 11 to 18). The research was to discover what subject knowledge capacity East London ICT teacher contemporaries had to develop and deliver a more computing-based curriculum, and thus perhaps move their pupils beyond a more traditional ICT curriculum.

description: The prevailing methodologies for visualizing AI risks have focused on technical issues such as data biases and model inaccuracies, often overlooking broader societal risks like job loss and surveillance. Moreover, these visualizations are typically designed for tech-savvy individuals, neglecting those with limited technical skills. To address these challenges, we propose the Atlas of AI Risks-a narrative-style tool designed to map the broad risks associated with various AI technologies in a way that is understandable to non-technical individuals as well. To both develop and evaluate this tool, we conducted two crowdsourcing studies. The first, involving 40 participants, identified the design requirements for visualizing AI risks for decision-making and guided the development of the Atlas. The second study, with 140 participants reflecting the US population in terms of age, sex, and ethnicity, assessed the usability and aesthetics of the Atlas to ensure it met those requirements. Using facial recognition technology as a case study, we found that the Atlas is more user-friendly than a baseline visualization, with a more classic and expressive aesthetic, and is more effective in presenting a balanced assessment of the risks and benefits of facial recognition. Finally, we discuss how our design choices make the Atlas adaptable for broader use, allowing it to generalize across the diverse range of technology applications represented in a database that reports various AI incidents.

description: The degree of entanglement in an open quantum system varies according to how information in the environment is read. A measure of this contextual entanglement is introduced based on quantum trajectory unravelings of the open system dynamics. It is used to characterize the entanglement in a driven quantum system of dimension $2\times\infty$ where the entanglement is induced by the environmental interaction. A detailed mechanism for the environment-induced entanglement is given.

Regeneration and small tree height increment in the interior Douglas-fir zone of the Rocky Mountain trench
Creators: name: Froese, Katrina
Publisher: name: University of British Columbia
Year: 2009

description: Data were collected in the Kootenay Dry Mild Interior Douglas-fir subzone variant (IDFdm2) of the Interior Douglas-fir biogeoclimatic ecological classification zone, Invermere Forest District. A total of 111 plots were sampled for plot-level data; 25 of these were subsampled for additional substrate information and spatially mapped. Objectives were to: 1) examine the explanatory ability of modelling techniques based on plot-level predictors and 2) examine the utility of spatial and substrate data for improving our knowledge of understory stand dynamics. The utility of imputation techniques as a method of predicting regeneration abundance was examined using the full data set. Imputation techniques performed moderately well. Subsampled data were used to examine regeneration abundance relative to substrate availability and spatial and aspatial competition and release indices. Substrate abundance was demonstrated to vary by moisture condition, as did substrate suitability for regeneration. Spatial indices showed interesting patterns between germinants and competition indices, and established regeneration and release indices. The spatial relationship between localized aggregations of regeneration and overstory trees, examined using Ripley's K(t) point pattern analysis, provided statistically significant results, but trends were generally inconsistent and could not be explained by available information. The utility of regression-based modelling as a method of predicting small tree height increment was examined using the full data set. Height increment models performed reasonably well. Small sample sizes were a limitation for some species. Subsampled data were used to examine spatial competition and release indices for model improvement. Spatial indices showed little potential for improvements over aspatial, plot-level indices, but provided an indication of the type of competition affecting small tree height increment. Both regeneration imputation and regression-based height increment modeling performed well, even with small data sets. Additional data for more sparsely sampled species are desirable. Further focus on substrate conditions and their effect on regeneration, within a multivariate context and for all species, is warranted. Subsurface properties are an unexplored avenue that merits investigation, since the analysis points to below-ground competition for resources. Finally, spatial tools may be more illustrative if data are gathered for both horizontal and vertical structures, or at larger scales.

description: This research describes and analyzes the commercial actions being conducted in six groups of producers bee located on the periphery of the state capital of Puebla, Mexico. We study the guidelines that have developed around the marketing as a discipline dedicated to analysis and implications of commercial actions, taking as a hub consumer preferences. There is some use of marketing tools in selling practices carried out by small groups of producers of honey, with the implementation of factor analysis. We found that the actions that develop commercial producers and honey producers are limited to continue with their daily practice of selling what they produce rather than mainstream approach mercadológico to produce what consumers are willing to buy and pay. The orientation of marketing that is focused primarily applied to the production phase, to ensure the acquisition of its product and promoting its sale, even without incorporating current trends show that the needs and preferences of consumers and the market where participating.

description: We derive the close, kinematic pair fraction and merger rate up to z ~ 1.2 from the initial data of the DEEP2 Redshift Survey. Assuming a mild luminosity evolution, the number of companions per luminous galaxy is found to evolve as (1+z)^{m}, with m = 0.51+-0.28; assuming no evolution, m = 1.60+-0.29. Our results imply that only 9% of present-day $L^{*}$ galaxies have undergone major mergers since z ~ 1.2 and that the average major merger rate is about 4* 10^{-4} h^{3} Mpc^{-3} Gyr^{-1} for z ~ 0.5 - 1.2. Most previous studies have yielded higher values.

description: Two-dimensional (2D) materials are outstanding platforms for exotic physics and emerging applications by forming interfaces. In order to efficiently take into account the substrate screening in the quasiparticle energies of 2D materials, several theoretical methods have been proposed previously, but only applicable to interfaces of two systems' lattice constants with certain integer proportion. In this work, we analytically showed the equivalence and distinction among different approximate methods for substrate dielectric matrices. We evaluated the accuracy of these methods, by applying them to calculate quasi-particle energies of hexagonal boron nitride interface systems (heterojunctions and bilayers), and compared with explicit interface calculations. Most importantly, we developed an efficient and accurate interpolation technique for dielectric matrices that made quasiparticle energy calculations possible for arbitrarily mismatched interfaces, which is extremely important for practical applications.
