description: Generalizing over temporal variations is a prerequisite for effective action recognition in videos. Despite significant advances in deep neural networks, it remains a challenge to focus on short-term discriminative motions in relation to the overall performance of an action. We address this challenge by allowing some flexibility in discovering relevant spatio-temporal features. We introduce Squeeze and Recursion Temporal Gates (SRTG), an approach that favors inputs with similar activations with potential temporal variations. We implement this idea with a novel CNN block that uses an LSTM to encapsulate feature dynamics, in conjunction with a temporal gate that is responsible for evaluating the consistency of the discovered dynamics and the modeled features. We show consistent improvement when using SRTG blocks, with only a minimal increase in the number of GFLOPs. On Kinetics-700, we perform on par with current state-of-the-art models, and outperform these on HACS, Moments in Time, UCF-101 and HMDB-51.

description: Collection of samples was carried near river Kuzha in nature reserve Shulgan-Tash by Laboratory of animal ecology and biomonitoring «EFA» in year 2017. In course of research, 20 taxons of macroinvertebrates of river Kuzha were determined: Ephemeroptera (dayfly), Plecoptera (stonefly) both in larval stage, which are the significant indicators of eutrophication level. Preliminary conclusion was made: life-sustaining activity of European beaver is making noticeable difference in life-sustaining activity of zoobenthos, even though beaver’s habitat development is low in this area, thus increasing percent of nonrheophilic species.

description: We investigate magnetization dynamics in asymmetric interlayer exchange coupled Py/Ru/Py trilayers using both vector network analyzer-based and electrically detected ferromagnetic resonance techniques. Two different ferromagnetic resonance modes, in-phase and out-of-phase, are observed across all three regimes of the static magnetization configurations, through antiparallel alignment at low fields, the spin-flop transition at intermediate fields, and parallel alignment at high fields. The nonmonotonic behavior of the modes as a function of the external field is explained in detail by analyzing the interlayer exchange and Zeeman energies and is found to be solely governed by the interplay of their dynamical components. In addition, the linewidths of both modes were determined across the three regimes and the different behaviors of the linewidths versus external magnetic field are attributed to mutual spin pumping induced in the samples. Interestingly, the difference between the linewidths of the out-of-phase and in-phase modes decreases at the spin-flop transition and is reversed between the antiparallel and parallel aligned magnetization states.

description: Let $X_n,...,X_1$ be i.i.d. random variables with distribution function $F$. A statistician, knowing $F$, observes the $X$ values sequentially and is given two chances to choose $X$'s using stopping rules. The statistician's goal is to stop at a value of $X$ as small as possible. Let $V_n^2$ equal the expectation of the smaller of the two values chosen by the statistician when proceeding optimally. We obtain the asymptotic behavior of the sequence $V_n^2$ for a large class of $F$'s belonging to the domain of attraction (for the minimum) ${\cal D}(G^α)$, where $G^α(x)=[1-\exp(-x^α)]{\bf I}(x \ge 0)$. The results are compared with those for the asymptotic behavior of the classical one choice value sequence $V_n^1$, as well as with the ``prophet value" sequence $V_n^p=E(\min\{X_n,...,X_1\})$.

From Process Consultation to a Clinical Model of Development Practice

Subjects: Community/Rural/Urban Development

description: This paper argues that two related concepts, process consultation and, in particular, the clinical perspective, developed by the organisational psychologist Edgar Schein, can improve the understanding, teaching and conduct of development practice. Process consultation - which is more than just the application of so called process approaches - and the clinical perspective are described, and the case for them is put, in relation to contrasts with ethnography and action research and in the light of contemporary debates about development studies and practice. Five particular aspects of the clinical model - the primacy of the "helpful intervention", the subservience of science to helping, its client centredness, it recognition of interventionists' financial and political status, and its overt normativeness are seen as particularly relevant to development practice. In conclusion, the clinical model is seen to pose four challenges for development studies - the creation of development's own theory of practice, the establishment of rigorous practitioner training programmes, the consequent institutional change, and an acknowledgement of the implications of development studies' disciplinary biases.

In particular, symmetric cumulants are considered. It is demonstrated also that statistical fluctuations due to a finite number of particles per event practically do not play a role for higher order PCA-based cumulants.

description: Lack of skills is arguably one of the most important determinants of high levels of unemployment and poverty. In response, policymakers often initiate vocational training programs in effort to enhance skill formation among the youth. Using a regression-discontinuity design, we examine a large youth training intervention in Nepal. We find, twelve months after the start of the training program, that the intervention generated an increase in non-farm employment of 10 percentage points (ITT estimates) and up to 31 percentage points for program compliers (LATE estimates). We also detect sizeable gains in monthly earnings. Women who start self-employment activities inside their homes largely drive these impacts. We argue that low baseline educational levels and non-farm employment levels and Nepal's social and cultural norms towards women drive our large program impacts. Our results suggest that the program enables otherwise underemployed women to earn an income while staying at home - close to household errands and in line with the socio-cultural norms that prevent them from taking up employment outside the house.

description: The article deals with the issues of investment activity in the dairy cattle industry. Taking into account the strategy of livestock development in the Ivanovo region and the priority of dairy cattle breeding in the agriculture of the region, our Department together with the Ministry of agriculture of Russia, have significantly increased the targets of the state program for the production of milk and dairy herd productivity. The task is to increase milk production by at least 80% to 275,000 tons, which will be solved through the construction of new dairy complexes, the effective use of livestock, the retrofitting of dairy farms, increasing state support and the development of dairy processing. Grouping of districts of the Ivanovo region on economic development of production and sale of dairy products showed that only 3 districts of the region are the most stable. Gavrilovo-Posadskiy, Rodniki and Shuya areas are sustainable because they have enterprises that are actively engaged in investments in the industry, as well as the production and marketing of milk and dairy products. Restriction of activity of the enterprises which are in the territory of the Ivanovo region making the forged production and containing substitutes of dairy fats of a vegetable origin. Quality control should ensure the interests of consumers and improve the competitiveness of the dairy industry as a whole.

description: We present a theoretical study of the structure and functionality of ferroelastic domain walls in tungsten trioxide, WO$_3$. WO$_3$ has a rich structural phase diagram, with the stability and properties of the various structural phases strongly affected both by temperature and by electron doping. The existence of superconductivity is of particular interest, with the underlying mechanism as of now not well understood. In addition, reports of enhanced superconductivity at structural domain walls are particularly intriguing. Focusing specifically on the orthorhombic $β$ phase, we calculate the structure and properties of the domain walls both with and without electron doping. We use two theoretical approaches: Landau-Ginzburg theory, with free energies constructed from symmetry considerations and parameters extracted from our first-principles density functional calculations, and direct calculation using large-scale, GPU-enabled density functional theory. We find that the structure of the $β$-phase domain walls resembles that of the bulk tetragonal $α_1$ phase, and that the electronic charge tends to accumulate at the walls. Motivated by this finding, we perform ab initio computations of electron-phonon coupling in the bulk $α_1$ structure and extract the superconducting critical temperatures , $T_c$, within Bardeen-Cooper-Schrieffer theory. Our results provide insight into the experimentally observed unusual trend of decreasing Tc with increasing electronic charge carrier concentration.

description: In this paper the dependence of wealth distribution and the velocity of money on the required reserve ratio is examined based on a random transfer model of money and computer simulations. A fractional reserve banking system is introduced to the model where money creation can be achieved by bank loans and the monetary aggregate is determined by the monetary base and the required reserve ratio. It is shown that monetary wealth follows asymmetric Laplace distribution and latency time of money follows exponential distribution. The expression of monetary wealth distribution and that of the velocity of money in terms of the required reserve ratio are presented in a good agreement with simulation results.

description: To be able to finance their physical assets and working capital costs, business schools mainly raise funds from any or a combination of the following: direct funding by the public sector or the government; income from providing educational services; debt (bank and bond); equity by private owners; public-private partnerships; research grants; and private sector endowment funds. This is a financing decision. But, it is the capital budgeting decision that matters! Business schools have to yield positive economic rates of return to become viable and attractive investment propositions; they must also yield positive non-pecuniary benefits. This paper provides a selective survey of the evidence on the core question of the rate of return to university education, and points out policy implications for business school education in Africa.

description: In spite of the apparent similarity of micro-branching instabilities in different brittle materials, we propose that the physics determining the typical length- and time-scales characterizing the post-instability patterns differ greatly from material to material. We offer a scaling theory connecting the pattern characteristics to material properties (like molecular weight) in brittle plastics like PMMA, and stress the fundamental differences with patterns in glass which are crucially influenced by 3-dimensional dynamics. In both cases the present ab-initio theoretical models are still too far from reality, disregarding some fundamental physics of the phenomena.

description: The newly observed $D_{sJ}^*$ family containing $D_{sJ}^{*}(2317)$, $D_{sJ}(2460)$ and $D_{sJ}(2632)$ attracts great interests. Determining their structure may be important tasks for both theorists and experimentalists. In this work we use the heavy quark effective theory (HQET) and a non-relativistic model to evaluate the production rate of $D_{sJ}^{*}(2317)$ from the decays of $ψ(4415)$, and we find that it is sizable and may be observed at BES III and CLEO, if it is a p-wave excited state of $D_s(1968)$. Unfortunately, the other two members of the family cannot be observed through decays of charmonia, because of the constraints from the final state phase space.

INFLUENCE OF INACTIVATED TOXINS OF E.COLI ON PHAGOCYTIC PROPERTIES OF NEUTROPHILIC GRANULOCYTES

description: The mechanisms of activation of the immune defense of a macro-organism in response to the ingestion of pathogens of infectious genesis are of practical interest for medicine and veterinary science, in particular, for developing and improving biological drugs for treatment and prevention. Given the relevance of the problem of the efficiency of preventive vaccination of colibacillosis in animals, the most promising areas in biotechnology are singled out, and they include the creation of immune preparations based on toxoid components of E. coli. This way, the effectors of innate immunity — neutrophilic granulocytes — come to the forefront of the immune response, and the scenario of the immune response to antigenic irritation will largely depend on their regulatory function. In this regard, the aim of our research was to study functional parameters of neutrophils under antigenic load, in this case – inactivated toxins of E. coli. White rats were used for biological research, and their blood was taken on the 1st, 3rd, 5th, and 7th days after the immunization performed with the toxoid components of E. coli to study the phagocytic activity of neutrophils, their capturing and digesting ability, and in order to determine the index of completion of phagocytosis. In the course of the experiment, it was found that, generally, E. coli toxins activate phagocytic immunity in vaccinated rats. At the same time, a preparation containing LT, ST, STX-toxins of E. coli stimulates the phagocytic activity of neutrophilic granulocytes in the first days after administration in comparison with separate use of toxins. The digesting and capturing ability of neutrophils was most pronounced on the third day of the research. Afterwards, there was a decrease in the functional activity of cells.

description: We study the phase structure of four-dimensional N=1 super Yang-Mills theories realized on D6-branes wrapping the RP^3 of a Z_2 orbifold of the deformed conifold. The non-trivial fundamental group of RP^3 allows for the gauge group to be broken to various product groups by Z_2 Wilson lines. We study the classical moduli space of theories in various pictures related by dualities including an M-theory lift. The quantum moduli space is analyzed in a dual IIB theory, where a complex curve contained in the target space plays a key role. We find that the quantum moduli space is made up of several branches, characterized by the presence or absence of a low energy U(1) gauge symmetry, which are connected at points of monopole condensation. The resulting picture of the quantum moduli space shows how the various gauge theories with different product gauge groups are connected to one another.

description: The outbreak of COVID-19 disease caused more than 100,000 deaths so far in the USA alone. It is necessary to conduct an initial screening of patients with the symptoms of COVID-19 disease to control the spread of the disease. However, it is becoming laborious to conduct the tests with the available testing kits due to the growing number of patients. Some studies proposed CT scan or chest X-ray images as an alternative solution. Therefore, it is essential to use every available resource, instead of either a CT scan or chest X-ray to conduct a large number of tests simultaneously. As a result, this study aims to develop a deep learning-based model that can detect COVID-19 patients with better accuracy both on CT scan and chest X-ray image dataset. In this work, eight different deep learning approaches such as VGG16, InceptionResNetV2, ResNet50, DenseNet201, VGG19, MobilenetV2, NasNetMobile, and ResNet15V2 have been tested on two dataset-one dataset includes 400 CT scan images, and another dataset includes 400 chest X-ray images studied. Besides, Local Interpretable Model-agnostic Explanations (LIME) is used to explain the model's interpretability. Using LIME, test results demonstrate that it is conceivable to interpret top features that should have worked to build a trust AI framework to distinguish between patients with COVID-19 symptoms with other patients.

description: While many studies have estimated the impacts of air pollution on crop yields on experimental plots, few have estimated these impacts under actual farm production conditions. This study econometrically estimates the impact of air pollution on corn and soybean yields, controlling for weather, soil quality and management practices, using farm-level data for the eastern United States. Ozone pollution was found to reduce yields for both crops. The mean elasticity of yield with respect to ozone exposure was -0.19 for corn and -0.54 for soybeans. The benefits of ozone standards to protect crops, measured in terms of crop revenues, range from $17 to $82 million depending on the stringency of the standard. Over 85 percent of the revenue gains are captured by three states: Maryland, North Carolina, and Virginia.
Klein-Nishina Effects in the Spectra of Non-Thermal Sources Immersed in External Radiation Fields

description: We study Klein-Nishina (KN) effects in the spectrum produced by a steady state, non-thermal source where rapidly accelerated electrons cool by emitting synchrotron radiation and Compton upscattering ambient photons produced outside the source. We focus on the case where the radiation density inside the source exceeds that of the magnetic field. We show that the KN reduction in the electron Compton cooling rate causes the steady-state electron spectrum to harden at energies above γ_{KN}, where γ_{KN}= 1/4ε_0 and ε_0=hν_0/m_ec^2 is the characteristic ambient photon energy. The source synchrotron spectrum thus shows a high-energy ``bump'' or excess even though the electron acceleration spectrum has no such excess. In contrast, the low-energy Compton gamma-ray spectrum shows little distortion because the electron hardening compensates for the KN decline in the scattering rate. For sufficiently high electron energies, however, Compton cooling becomes so inefficient that synchrotron cooling dominates -- an effect omitted in most previous studies. The hardening of the electron distribution thus stops, leading to a rapid decline in Compton gamma-ray emission, i.e., a strong spectral break whose location does not depend on the maximum electron energy. This break can limit the importance of Compton gamma-ray pair production on ambient photons and implies that a source's synchrotron luminosity may exceed its Compton luminosity even though the source magnetic field energy density is smaller than the ambient radiation energy density. We discuss the importance of these KN effects in blazars, micro-quasars, and pulsar binaries.

description: Transport phenomena play a crucial role in modern physics and applied sciences. Examples include the dissipation of energy across a large system, the distribution of quantum information in optical networks, and the timely modeling of spreading diseases. In this work, we experimentally prove the feasibility of disordered quantum walks to realize a quantum simulator that is able to model general subdiffusive phenomena, exhibiting a sublinear spreading in space over time. Our experiment simulates such phenomena by means of a finely controlled insertion of various levels of disorder during the evolution of the walker, enabled by the unique flexibility of our setup. This allows us to explore the full range of subdiffusive behaviors, ranging from anomalous Anderson localization to normal diffusion.

description: The role of health knowledge in consumer use of nutritional labels on food packages is explored using data from the 1995 Diet and Health Knowledge Survey. Two types of label use models, a binary choice label use model and a level of label use model, are employed with particular attention given to the endogeneity of health knowledge. The binary choice model is concerned with factors affecting the probability of label use. The level of label use model deals with factors affecting the number of food products in which label use occurred. The results show that health knowledge has a significant role in increasing label use.

Both random intrinsic curvature and inhomogeneous bending rigidity are found to result in a remarkably wide distribution of cyclization probabilities. For short DNA segments, the range of the distribution reaches several orders of magnitude for even completely random sequences. The ensemble averaged values of the cyclization probability are also calculated, and the connection to the recent experiments is discussed.

A longitudinal study of the role of phonological awareness in early reading development in English speaking (L1) and English as a second-language speaking (ESL) students
Creators: name: Hoption, Claire Audrey
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the role phonological processing (PP) skills play in identifying English as a Second language (ESL) students at risk of early reading failure compared to native English speaking (L1) students at risk of early reading failure. This study also examined whether early PP skills continue to be good predictors of reading ability for L1 and ESL learners over time. This 4 year longitudinal study began in 1996 with three grades of participants Junior Kindergarteners, Senior Kindergarteners, and Grade 1 students. There were 156 ESL students and 195 L1 students in 1996, and among the ESL participants, the two most predominant languages were Punjabi and Chinese. Students were further classified as either reading disabled (RD) or normal achieving readers (NA) based on their scores on a reading measure. All students were given tasks to assess their word reading, phonological awareness, syntactic awareness, spelling and working memory skills in English over the years, although in some years certain groups of participants were administered additional and different tasks depending on their grade level. For example, math tasks were administered only to grade 3 and 4 children in 1999. Although there were a few observable differences on some of the measures between the two language groups, this study found no significant differences in early reading development between L1 and ESL learners overall. In addition, this study found evidence of a positive and stable relationship between PP skills and reading ability in ESL and L1 students.

description: A new technology of basic tillage for the production of crops in dry farming. The technology includes a combination of loosening, chiseling, mixing the soil with mulching the surface of the arable land. The technical characteristic of the developed tillage implements aggregated with tractors of traction classes 3 and 5 is given. It is established that the use of frontal plows PBFR improves the performance of arable units, allowing to improve the quality of the main tillage in comparison with the known General purpose ploughshares PLN and PBS.

description: We propose an eclipsing light-curve diagnosis for black-hole accretion flows. When emission from an inner accretion disk around a black hole is occulted by a companion star, the observed light curve becomes asymmetric at ingress and egress on a time scale of 0.1-1 seconds. This light-curve analysis provides a means of verifying the relativistic properties of the accretion flow, based on the special/general relativistic effects of black holes. The ``skewness'' for the eclipsing light curve of a thin disk is $\sim 0.08$, whereas that of a slim disk is $\sim 0$, since the innermost part is self-occulted by the disk's outer rim.

description: We study non-equilibrium dynamics induced by a sudden quench of strongly correlated Hamiltonians with all-to-all interactions. By relying on a Sachdev-Ye-Kitaev (SYK) based quench protocol, we show that the time evolution of simple spin-spin correlation functions is highly sensitive to the degree of locality of the corresponding operators, once an appropriate set of fundamental fields is identified. By tracking the time-evolution of specific spin-spin correlation functions and their decay, we argue that it is possible to distinguish between operator hopping and operator growth dynamics; the latter being a hallmark of quantum chaos in many-body quantum systems. Such observation, in turn, could constitute a promising tool to probe the emergence of chaotic behavior, rather accessible in state-of-the-art quench setups.

description: There is a substantial controversy in the economics literature over the magnitude of the expenditure elasticity for food grain in China that is caused, to a large extent, by whether time-series or cross-section data are used in the analysis. A set of reasonable elasticities for a complete demand system is estimated by using a panel of county level data in Guangdong Province for the last ten years. The results show that food grain has a small positive income elasticity, implying that food grain is not an inferior good in China. The reason that consumption per capita has not increased during a period of rapid economic growth in income is that the relative prices of the food and non-food substitutes for food grain have decreased.

Non-linear Osmotic Brush Regime: Simulations and mean-field theory

description: We investigate polyelectrolyte brushes in the osmotic regime using both theoretical analysis and molecular dynamics simulation techniques. In the simulations at moderate Bjerrum length, we observe that the brush height varies weakly with grafting density, in contrast to the accepted scaling law, which predicts a brush thickness independent of the grafting density. We show that such behavior can be explained by considering lateral electrostatic effects (within the non-linear Poisson-Boltzmann theory) combined with the coupling between lateral and longitudinal degrees of freedom due to the conserved polymer volume (which are neglected in scaling arguments). We also take the non-linear elasticity of polyelectrolyte chains into consideration, which makes significant effects as chains are almost fully stretched in the osmotic regime. It is shown that all these factors lead to a non-monotonic behavior for the brush height as a function of the grafting density. At large grafting densities, the brush height increases with increasing the grafting density due to the volume constraint. At small grafting densities, we obtain a re-stretching of the chains for decreasing grafting density, which is caused by lateral electrostatic contributions and the counterion-condensation process at polyelectrolyte chains. These results are obtained assuming all counterions to be trapped within the brush, which is valid for sufficiently long chains of large charge fraction.

Mugideiriflora portugallica

description: Mugideiriflora portugallica E.M.FRIIS, P.R.CRANE et K.R.PEDERSEN, 2020
Text-fig. 2a, b
Description and remarks. Mugideiriflora portugallica is based on a single small, partly abraded, early anthetic flower (Text-fig. 2a) that has a multiparted perianth, androecium and gynoecium and was recovered from the Catefica mesofossil flora (for a full description and discussion of the species see Friis et al. 2020a). Additional specimens are preserved at very early developmental stages. The receptacle is slightly concave, but with a short conical apex in the gynoecial region (Text-fig. 2a). There are about 50 laminar tepals, 50 stamens and more than 50 carpels, all apparently in a spiral arrangement (Text-fig. 2b).
Affinity and other occurrences. Phylogenetic assessment suggests that Mugideiriflora portugallica is closely related to members of extant Austrobaileyales, although a possible affinity with members of extant Magnoliales cannot be excluded (Friis et al. 2020a).
Mugideiriflora portugallica is currently known only from the Catefica mesofossil flora where it is recorded from samples collected near the base of the exposure.

description: This paper examines the impacts of the Northeast Interstate Dairy Compact (Compact) on the Women, Infants and Children (WIC) program using an autoregressive-moving average (ARMA) model and data from Boston and Hartford. While the results for Boston indicate that the difference between the net fluid milk price paid by WIC program and the forecasted fluid milk price with no Compact in effect was not significant over the period of July 1997 to June 1998, the results for Hartford suggest that the net price paid by WIC was significantly greater than the forecasted price with no Compact in effect over the same period. A similar analysis of the changes in markups suggests that the increase in the net fluid milk price paid by the WIC program in Hartford was largely due to increased markups.

description: The most important task at all stages of development of modern agriculture is to increase the yield and quality of grain. Plant growth regulators can play an important role in this. In this paper, the influence of winter wheat seed treatment with fungicide Polaris and the use оf Melafen growth regulator in winter wheat crops in the Ufa region of the Republic of Bashkortostan are considered. Treatment of seeds with fungicide Polaris in combination with preparations for the care of crops provided a yield of 58.9-68.7 centner/ha. The use of Melafen growth regulators in the experiment in the Ufa region of the Republic of Bashkortostan affected the increase in crop yield to 63.6-74.1 centner/ha, depending on the processing scheme used.

description: Coset methods are used to construct the action describing the dynamics associated with the spontaneous breaking of the local supersymmetries. The resulting action is an invariant form of the Einstein-Hilbert action, which in addition to the gravitational vierbein, also includes a massive gravitino field. Invariant interactions with matter and gauge fields are also constructed. The effective Lagrangian describing processes involving the emission or absorption of a single light gravitino is analyzed.
