Мировые тенденции указывают на изменения в структуре существенных факторов экономики: рост значимости знаний, талантов, уникальных способностей, входящих в понятие когнитивной составляющей результата, особенно применительно к инновационной деятельности. Это означает повышение роли человека и всего того, что способствует развитию его и раскрытию его качеств. Для России проблема в этой области сводится к задачам социального развития, улучшения качества жизни, формирования талантов и привлечения их к инновационной деятельности. Значимость взаимодействий участников инновационной деятельности обусловлена существенным влиянием тесного сотрудничества в создании знаний и технологий в виду углубления междисциплинарной составляющей в генерировании знаний.

description: Graphics Processing Units (GPUs) have revolutionized the HPC landscape. The first generation of exascale supercomputers is currently being built, and most of these systems will have GPUs as their main computing platform. The performance of GPU applications strongly depends on how the software has been optimized for the hardware. There are many different implementations and code optimizations to consider that can also be parameterized, creating vast search spaces that are infeasible to search by hand. As such, automated performance tuning (auto-tuning) techniques are crucial to optimize such applications.

 In this tutorial, you will learn how to use Kernel Tuner, an easy-to-use tool for auto-tuning GPU code using simple Python scripts. Kernel Tuner supports OpenCL, CUDA, C++, and Fortran. We take a step-by-step approach to explain the auto-tuning basics, building up to more complex search spaces with many tunable parameters and inter-dependencies.
title: Professional Doctorate in Sport and Exercise Psychology
Creators: name: Crossen, W
Publisher: name: Liverpool John Moores University
Year: 2021

description: With the recent development in the field of sport psychology professional training, the value of the professional doctorate has become increasingly apparent due to its ability in allowing neophyte practitioners to develop competence required of practitioner psychologists, and translate knowledge in research to the workplace. The present portfolio contains a blend of research and practice components, complimented by significant reflective practice content, to demonstrate the author’s competency in ethics and professional standards, consultancy, research and teaching and training, whilst demonstrating aspects of originality and the generation of new knowledge for the field. The portfolio commences with the author’s reflective accounts across key professional standards, consultancy, research, and dissemination experiences, identifying the meaningful learning experiences that most developed the author both personally and professionally. Following this are three consultancy case studies, which provide an in-depth account of the staged-process the author underwent in the creation, development, and monitoring of an intervention(s) when working with golf, running, and football athletes. Within this, ongoing critical analysis and reflective practice allowed the author to develop an effective, congruent philosophy of practice in humanism and holism, facilitating a more authentic sense of self within their practitioner identity. The portfolio then explores the teaching and training elements of the professional doctorate, including the negotiation of the environment and key stakeholders within the process, the construction of an applied, active learning environment for the teaching of sport psychology, and the key pedagogical frameworks and taxonomies that underpinned the approach. Attention then switches to the research elements of the portfolio, with the systematic review and two empirical papers attempting to bridge the gap between research and practice within the topic of Identity in disability sport, including investigation of the psychological well-being experiences of stakeholders working in Para-Football and the development of a psychological well-being culture. Within this, key ontological and epistemological paradigms enabled the author to navigate a coherent and congruent practitioner–researcher identity. Ultimately, the reflective practice commentary (meta-reflection) provides a summary of the process, with the professional doctorate providing the candidate with an authentic connection between their work and a broader transcendent life purpose beyond the self (Bailey & Madden, 2016).

description: We calculate the masses of the $1^{-+}$ four quark states which decay dominantly into $ρπ$ and $ηπ$ respectively by QCD sum rules approach. We include the zero mode contribution and find it plays an important role in the sum rules. We predict that the masses of the states $ηπ$ and $ρπ$ both are 1.4-1.5 GeV. This is close to the experimental candidates $π_1(1370)$ and $π_1(1440)$.

description: Charge disproportionation (CD) and spin differentiation in Na$_{1/2}$CoO$_2$ are studied using the correlated band theory approach. The simultaneous CD and gap opening seen previously is followed through a first order charge disproportionation transition 2Co$^{3.5+} \to$ Co$^{3+}$+Co$^{4+}$, whose ionic identities are connected more closely to spin (S=0, S=1/2 respectively) than to real charge. Disproportionation in the Co $a_g$ orbital is compensated by opposing charge rearrangement in other 3d orbitals. At the transition large and opposing discontinuities in the (all-electron) kinetic and potential energies are slightly more than balanced by a gain in correlation energy. The CD state is compared to characteristics of the observed charge-ordered insulating phase in Na$_{1/2}$CoO$_2$, suggesting the Coulomb repulsion value $U$ is concentration-dependent, with $U(x=1/2)\simeq$3.5 eV.

description: We studied the insulator-quantum Hall conductor transition which separates the low-field insulator from the quantum Hall state of the filling factor $ν=4$ on a gated two-dimensional GaAs electron system containing self-assembled InAs quantum dots. To enter the $ν=4$ quantum Hall state directly from the low-field insulator, the two-dimensional system undergoes a crossover from the low-field localization to Landau quantization. The crossover, in fact, covers a wide range with respect to the magnetic field rather than only a small region near the critical point of the insulator-quantum Hall conductor transition.

description: In computational fluid dynamics, there is an inevitable trade off between accuracy and computational cost. In this work, a novel multi-fidelity deep generative model is introduced for the surrogate modeling of high-fidelity turbulent flow fields given the solution of a computationally inexpensive but inaccurate low-fidelity solver. The resulting surrogate is able to generate physically accurate turbulent realizations at a computational cost magnitudes lower than that of a high-fidelity simulation. The deep generative model developed is a conditional invertible neural network, built with normalizing flows, with recurrent LSTM connections that allow for stable training of transient systems with high predictive accuracy. The model is trained with a variational loss that combines both data-driven and physics-constrained learning. This deep generative model is applied to non-trivial high Reynolds number flows governed by the Navier-Stokes equations including turbulent flow over a backwards facing step at different Reynolds numbers and turbulent wake behind an array of bluff bodies. For both of these examples, the model is able to generate unique yet physically accurate turbulent fluid flows conditioned on an inexpensive low-fidelity solution.

title: Physiology and molecular genetic regulation of flowering in potential ecotypes of Fragaria vesca selected from the UK
Creators: name: Alsabehi, Rashed Mosaed H.
Publisher: name: University of Reading
Year: 2018

description: Physiological and molecular genetic studies in the model plant Fragaria vesca were conducted to further understand the regulation of flowering in perennial plants. Different populations of F. vesca were collected from sites in the UK with different geographical and environmental conditions. These populations were propagated and studied in a common garden experiment at Reading University. Initial investigation into growth and floral emergence responses were carried out across the whole annual cycle and comparisons were made between three populations and with three different crown sizes. Further experiments were conducted on floral emergence using a single, large, crown size. Variation in floral initiation between populations was investigated and the specific effect of photoperiod on floral induction between representative northern and southern populations was tested in both outdoor and controlled environments. A new, simulated model was developed based on actual environmental measurements and used to test the responses of plants to a compressed annual cycle. Phylogenetic studies using barcoding genes to confirm species identification were carried out and the genetic sequence of a number of key floral genes was compared. Gene expression analysis was carried out for FvCONSTANS, FvFLOWERING LOCUS T1, FvTERMINAL FLOWER1 and FvSUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 in both inductive and non-inductive or selective conditions. Ecotypic variations were apparent between populations and these suggested a potential level of local adaptation. A representative northerly population demonstrated earlier floral induction in longer short day conditions compared to representative southerly populations. The critical day length for short day flowering, therefore, appeared to be longer in the northern populations. A high level of juvenility in seed propagated material made the comparison between these, and vegetative propagated plants, with a view to looking for differential heritability in adaptations, impractical. The new, compressed annual cycle model, based on actual environmental measurements, was run successfully. Differential timings of the peak in FvCO suggested that FvCO was responsive to a short day signal. The patterns of FvFTJ, FvTFLJ and FvSOCJ gene expression were in line with the expression models of floral induction in F. vesca and differences in expression appeared to support that northern and southern populations were differentially sensitive to the shortness of days, suggesting the potential of local adaptation.
title: The perspectives of male academic staff and postgraduate students on the effects of globalisation on higher education and cultural identity: a case study at a college of education in Saudi Arabia
Creators: name: Alsewiket, Ahmad Abdullah
Publisher: name: University of Reading
Year: 2018

description: The philosophy and policy of higher education in Saudi Arabia, since its establishment, have been based on the teachings and ethics of Islam and on the accompanying Islamic values and culture. Higher education thus plays a major role in developing a doctrine of loyalty to God (Allah) and in providing students with Islamic cultural foundations, with the aim of preparing citizens who are scientifically and intellectually qualified to participate in serving their nation. However, globalisation has led to a shift in the goals of higher education and has raised many challenges for universities in the country. How can Saudi Arabia reform and develop its higher education system, achieve economic prosperity and become a global competitor-all while maintaining its traditional role in preserving the country's core cultural values, founded on Islamic principles? This study explores the changing role of higher education in Saudi Arabia, in relation to globalisation and cultural identity, through the perspectives of academic staff and postgraduate students at the College of Education at an 'Academic University ' in Saudi Arabia. The study adopted the interpretive paradigm with an embedded mixed methods design. A case study of one higher education institution was undertaken, and three methods were used to collect data: a survey (n= 140), interviews (n= 15) and documentary review. The study revealed that globalisation has posed many challenges for higher education in Saudi Arabia. It appears that the traditional purposes of higher education institutions have shifted, to some extent. For instance, serving the labour market seems to have become the essence of higher education goals. Responding to issues of globalisation-such as competition and ranking amongst global universities-is now being considered for higher education institutions in Saudi Arabia. Globalisation also seems to have had significant effects on the cultural identity of Saudi society, as can be seen through the increased spread of the English language, which has negatively affected the use of Arabic. Globalisation has played a key role in spreading the Western lifestyle within Saudi society, and within the younger generation in particular. This may be seen as a threat to the society's cultural identity.

description: We examine the spatial determinants of the prevalence of poverty for small spatially defined populations in rural Malawi. Poverty prevalence was estimated using a small-area poverty estimation technique. A theoretical approach based on the risk chain conceptualization of household economic vulnerability guided our selection of a set of potential risk and coping strategies—the determinants of our model—that could be represented spatially. These were used in two analyses to develop global and local models, respectively. In our global model—a spatial error model—only eight of the more than two dozen determinants selected for analysis proved significant. In contrast, all of the determinants considered were significant in at least some of the local models of poverty prevalence. The local models were developed using geographically weighted regression. Moreover, these models provided strong evidence of the spatial nonstationarity of the relationship between poverty and its determinants. That is, in determining the level of poverty in rural communities, where one is located in Malawi matters. This result for poverty reduction efforts in rural Malawi implies that such efforts should be designed for and targeted at the district and subdistrict levels. A national, relatively inflexible approach to poverty reduction is unlikely to enjoy broad success.

description: Using the IRAM Plateau de Bure Interferometer, we have searched for CO(3-2) emission from the dusty Lyman break galaxy Westphal-MD11 at z = 2.98. Our sensitive upper limit is surprisingly low relative to the system's 850 um flux density and implies a far-IR/CO luminosity ratio as elevated as those seen in local ultraluminous mergers. We conclude that the observed dust emission must originate in a compact structure radiating near its blackbody limit and that a relatively modest molecular gas reservoir must be fuelling an intense nuclear starburst (and/or deeply buried active nucleus) that may have been triggered by a major merger. In this regard, Westphal-MD11 contrasts strikingly with the lensed Lyman break galaxy MS1512-cB58, which is being observed apparently midway through an extended episode of more quiescent disk star formation.

The classical limit of non-integrable quantum systems

Publisher: name: arXiv

description: The classical limit of non-integrable quantum systems is studied. We define non-integrable quantum systems as those which have, as their classical limit, a non-integrable classical system. In order to obtain this limit, the self-induced decoherence approach and the corresponding classical limit are generalized from integrable to non-integrable systems. In this approach, the lost of information, usually conceived as the result of a coarse-graining or the trace of an environment, is produced by a particular choice of the algebra of observables and the systematic use of mean values, that project the unitary evolution onto an effective non-unitary one. The decoherence times computed with this approach coincide with those of the literature. By means of our method, we can obtain the classical limit of the quantum state of a non-integrable system, which turns out to be a set of unstable, potentially chaotic classical trajectories contained in the Wigner transformation of the quantum state.

description: [Objectives] The purpose was to investigate the characteristics of soil seed bank of typical plant communities in hilly area of Funiu Mountain. [Methods] The seed density, number of species and species composition of the soil seed bank of typical plant communities such as Themeda japonica, Imperata cylindrica, Vitex negundo, Quercus acutissima, Robinia pseudoacacia, Platycladus orientalis and Populus canadensis in the surface, top 0-5 and top 5-10 cm soil were studied. [Results] The seed reserves of plant communities at different succession stages were (220.00±95.39) – (2 650.00±1 064.52) seeds/m2. A total of 48 species were counted in the seed bank, belonging to 45 genera in 22 families. Total 27 species were identified in the above-ground vegetation, belonging to 25 genera in 14 families. In the shallow soil where the seeds gathered, the seed densities of Imperata cylindrica and Themeda japonica were relatively low. The reserves of plant communities with different naturalness degrees were (403.33±64.29) – (2 110.00±356.79) seeds/m2. A total of 67 species were counted in the seed bank, belonging to 64 genera in 37 families. A total of 45 species were identified in the above-ground vegetation, belonging to 43 genera in 28 families. In the soil layers of 0-5 and 5-10 cm, the seed density of natural secondary Q. acutissima was higher than those of planted P. canadensis, P. orientalis and R. pseudoacacia. In each soil layer, the species number of natural secondary Q. acutissima forest was slightly smaller than those of planted P. canadensis, P. orientalis and R. pseudoacacia forests. [Conclusions] The seeds in the soil seed bank may not completely come from existing above-ground vegetation. Manual assistance is required for vegetation restoration or reconstruction relying on soil seed bank, to ensure the direction of community succession.

description: With prosperity of applications on smartphones, energy saving for smartphones has drawn increasing attention. In this paper we devise Phone2Cloud, a computation offloading-based system for energy saving on smartphones in the context of mobile cloud computing. Phone2Cloud offloads computation of an application running on smartphones to the cloud. The objective is to improve energy efficiency of smartphones and at the same time, enhance the application's performance through reducing its execution time. In this way, the user's experience can be improved. We implement the prototype of Phone2Cloud on Android and Hadoop environment. Two sets of experiments, including application experiments and scenario experiments, are conducted to evaluate the system. The experimental results show that Phone2Cloud can effectively save energy for smartphones and reduce the application's execution time.

description: Motivated by the unconventional properties and rich phase diagram of NaxCoO2 we consider the electronic and magnetic properties of a two-dimensional Hubbard model on an isotropic triangular lattice doped with electrons away from half-filling. Dynamical mean-field theory (DMFT) calculations predict that for negative inter-site hopping amplitudes (t<0) and an on-site Coulomb repulsion, U, comparable to the bandwidth, the system displays properties typical of a weakly correlated metal. In contrast, for t>0 a large enhancement of the effective mass, ferromagnetism and a Curie-Weiss magnetic susceptibility are found in a broad electron doping range. Our observation of Nagaoka ferromagnetism is consistent with the A-type antiferromagnetism (i.e. ferromagnetic layers stacked antiferromagnetically) observed in neutron scattering experiments on NaxCoO2. We propose that `Curie-Weiss metal' phase observed in NaxCoO2 is a consequence of the crossover from ``bad metal'' with incoherent quasiparticles at temperatures T>T* and Fermi liquid behavior with enhanced parameters below T*, where T* is a low energy coherence scale induced by strong local Coulomb electron correlations. We propose a model which contains the charge ordering phenomena observed in the system which, we propose, drives the system close to the Mott insulating phase even at large dopings.

description: We consider the Larkin model of a directed polymer with Gaussian-distributed random forces, with the addition of a resetting process whereby the transverse position of the end-point of the polymer is reset to zero with constant rate $r$. We express the average over disorder of the mean time to absorption by an absorbing target at a fixed value of the transverse position. Thanks to the independence properties of the distribution of the random forces, this expression is analogous to the mean time to absorption for a diffusive particle under resetting, which possesses a single minimum at an optimal value $r^\ast$ of the resetting rate . Moreover, the mean time to absorption can be expanded as a power series of the amplitude of the disorder, around the value $r^\ast$ of the resetting rate. We obtain the susceptibility of the optimal resetting rate to disorder in closed form, and find it to be positive.

Continuum effects on the pairing in neutron drip-line nuclei studied with the canonical-basis HFB method

description: The canonical-basis HFB method provides an efficient way to describe pairing correlations involving the continuum part of the single-particle spectrum in coordinate-space representations. It can be applied to super-conducting deformed drip-line nuclei as easily as to stable or spherical nuclei. This method is applied to a simulation of the approach to the neutron drip line. It turns out that the HFB solution has a stronger pairing and a smaller deformation as the Fermi level is raised. However, such changes are smooth and finite. No divergences or discontinuities of the radius or other quantities are found in the limit of zero Fermi energy. The nuclear density continues to be localized even a little beyond the drip line.

description: We present a theory of single-electron tunneling transport through a ferromagnetic nanoparticle in which particle-hole excitations are coupled to spin collective modes. The model employed to describe the interaction between quasiparticles and collective excitations captures the salient features of a recent microscopic study. Our analysis of nonlinear quantum transport in the regime of weak coupling to the external electrodes is based on a rate-equation formalism for the nonequilibrium occupation probability of the nanoparticle many-body states. For strong electron-boson coupling, we find that the tunneling conductance as a function of bias voltage is characterized by a large and dense set of resonances. Their magnetic field dependence in the large-field regime is linear, with slopes of the same sign. Both features are in agreement with recent tunneling experiments.

Particular attention is given to the effect of participation in marketing and supply cooperatives on the success of small farms. Using modified net farm income per dollar of assets and operator’s labor and management income as measures of success, results show participation in marketing and supply cooperatives is positively correlated with success. Further, analysis findings indicate farm size, controlling for variable and fixed costs, type of ownership, management strategies used, working off the farm, and age of the operator are important factors that influence profitability (modified net farm income per dollar of assets and operator’s labor and management income) and success.

description: Mobile devices have become a popular tool for ubiquitous learning in recent years. Multiple mobile users can be connected via ad hoc networks for the purpose of learning. In this context, due to limited battery capacity, energy efficiency of mobile devices becomes a very important factor that remarkably affects the user experience of mobile learning. Based on the artificial bee colony (ABC) algorithm, we propose a new clustering protocol, namely BeeCup, to save the energy of mobile devices while guaranteeing the quality of learning. The BeeCup protocol takes advantage of biologically-inspired computation, with focus on improving the energy efficiency of mobile devices. It first estimates the number of cluster heads (CHs) adaptively according to the network scale, and then selects the CHs by employing the ABC algorithm. In case some CHs consume energy excessively, clusters will be dynamically updated to keep energy consumption balanced within the whole network. Simulation results demonstrate the effectiveness and superiority of the proposed protocol.

description: In this work we present analytic and numerical treatments of the gravitational wave signal from a pulsar which includes spindown. We consider phase corrections to a received monochromatic signal due to rotational and elliptical orbital motion of the Earth, as well as perturbations due to Jupiter and the Moon. We discuss the Fourier transform of such a signal, which is expressed in terms of well known special functions and lends itself to a tractable numerical analysis.

description: Using results on soft-collinear factorization for inclusive B-meson decay distributions, a systematic study of the partial B->Xs+gamma decay rate with a cut E_gammaXs+gamma branching ratio with E_gamma<1.8 GeV is Br(B->Xs+gamma)=(3.44+-0.53+-0.35)*10^{-4}, where the errors refer to perturbative and parameter uncertainties, respectively. The implications of larger theory uncertainties for New Physics searches are explored with the example of the type-II two-Higgs-doublet model.

title: Sustainability and medicines waste: investigating public attitudes towards the reuse of medicines returned to community pharmacies

description: Introduction The financial cost of medicinal waste in the UK is estimated as £300 million per year for prescribed medicines. Medicines reuse relates to the idea that unused prescribed medicines returned by one patient to a pharmacy can be re-dispensed to another patient as a strategy for reducing medicinal waste in the UK. Aims This thesis aimed to capture people’s beliefs and intentions towards reusing medicines that are returned to the pharmacies, using the Theory of Planned Behaviour (TPB). Methods and analysis The research uses a mixed method study design, using qualitative interviews to identify themes that were then classified using TPB (phase 1), in order to develop and validate a Medicine Reuse Questionnaire (MRQ) (phase 2), which was used to quantify the views of a large sample of respondents drawn from around the UK (phase 3) about medicines reuse. Results and discussions Medicines reuse was defined and people’s ideas about advantages and disadvantages, who might approve or disapprove, and factors that would impede or facilitate reusing medicines were mapped using thematic analysis. The MRQ was valid (confirmatory factor analysis showed the factor loading of all items to be >0.5; the item level content validity index was > 0.8) and reliable (Cronbach’s alpha measuring internal consistency of the direct measures items was >0.7; Pearson’s correlation measuring stability of the indirect measures items was >0.5). A total of 1,003 valid responses were analysed and subjective norms had the strongest positive effect on intentions with standardized path coefficient of 0.55 (p < 0.001, n = 1003). Conclusion This research suggests that people living in the UK have positive intentions and could reuse medicine in the future. However, ensuring safety and quality of medicines that will be offered for reuse is vital for people to agree to reuse medicines in the future.

description: This is the first of a series of articles in which we are going to study the regularized determinants of the Laplacians of Calabi Yau metrics acting on (0,q) forms on the moduli space of CY manifolds with a fixed polarization. It is well known that in case of the elliptic curves the Kronecker limit formula gives an explicit formula for the regularized determinants of the flat metrics with fixed volume on the elliptic curves. The following formula holds in this case; the regularized determinant is the product of the imaginary part of the complex number in the Siegel upper half plane with the Dedekind eta function. It is well known fact that the Dedekind eta function in power 24 is a cusp automorphic form of weight 12 related to the discriminant of the elliptic curve. Thus we can view that the regularized determinant is the norm of a section of some power of the line bundle of the classes of cohomologies of (1,0) forms of the elliptic curves over its moduli space. Our purpose is to generalize this fact in the case of CY manifolds. In this paper we will establish the local analogue of the Kronecker limit formula for CY manifolds.

description: Nonagricultural factors impact land values to cause a divergence of discounted cash rents for agricultural land and land values in Georgia. General economic factors are represented by per capita income in nonmetro areas. Cash rents for cropland and pasture have positive impacts on land values. Nonagricultural factors are stronger influences on land values than are cash rents. Greater effective demand exists for pasture than for cropland because pasture is subject to relatively more pricing pressure in northern counties with higher incomes and population. Increased land values have led to increased net wealth for Georgia agricultural producers.

description: By feeding current into the topmost $\mathrm{Cu_2O_4}$-layer of a mesa etched into the surface of a $\mathrm{Bi_2Sr_2CaCu_2O_{8+x}}$ (BSCCO) single crystal, we measured its superconducting critical value from a sharp upturn or break in current-voltage characteristics of the mesas. From this, we estimate the sheet critical current density of a single $\mathrm{Cu_2O_4}$ plane to be $\sim$\ 0.3-0.7 A/cm at 4.5 K, corresponding to the bulk current density of $2-5\ \mathrm{MA/cm^2}$. These values are among the largest ever measured for BSCCO single crystals, thin films and tapes.

description: Biofuels have been promoted to achieve energy security and as a solution to mitigating climate change. This research presents a framework to examine the extent to which biofuel mandates and subsidies reduce gasoline consumption and their implications for the food and fuel prices. A dynamic, multi-market equilibrium model, Biofuel and Environmental Policy Analysis Model (BEPAM), is used to estimate the effects of these policies on cropland usage between food crops and fuel crops and food and fuel prices, and to analyze the incentives provided by alternative policies for the mix of biofuels from corn and various cellulosic feedstocks that are economically viable over the 2007-2022 period. The provision of biofuel subsidies that accompany the mandate under the Renewable Fuel Standard (RFS) is found to significantly change this mix in favor of cellulosic biofuels produced from high yielding grasses and reduce the adverse impact of the RFS alone on food prices.
