description: We investigate the relation between the asymptotic circular velocity, V_c, and the central stellar velocity dispersion, sigma_c, in galaxies. We consider a new sample of high surface brightness spiral galaxies (HSB), low surface brightness spiral galaxies (LSB), and elliptical galaxies with HI-based V_c measurements. We find that: 1) elliptical galaxies with HI measurements fit well within the relation; 2) a linear law can reproduce the data as well as a power law (used in previous works) even for galaxies with sigma_c < 70 km/s; 3) LSB galaxies, considered for the first time with this respect, seem to behave differently, showing either larger V_c values or smaller sigma_c values.

description: We study the dynamics of a two-level quantum system interacting with an external electromagnetic field periodic and quasiperiodic in time. The quantum evolution is described exactly by the classical equations of motion of a gyromagnet in a time-dependent magnetic field. We prove that this classical system is integrable as a consequence of the underlying unitary quantum dynamics. As a consequence, for the periodic case: i) rigorous assessment of the validity of the rotating-wave approximation (RWA) becomes possible even beyond the assumptions of resonance and weak coupling (the latter conditions are also shown to follow from the method of averaging); ii) we determine conditions for the realization of the quantum NOT operation beyond the RWA, by means of classical stroboscopic maps. The results bear upon areas as diverse as quantum optics, nuclear magnetic resonance, and quantum computation.

description: Nuclear density functional theory is the prevalent theoretical framework for accurately describing nuclear properties at the scale of the entire chart of nuclides. Given an energy functional and a many-body scheme (e.g., single- or multireference level), the predictive power of the theory depends strongly on how the parameters of the energy functionals have been calibrated with experimental data. Expanded algorithms and computing power have enabled recent optimization protocols to include data in deformed nuclei in order to optimize the coupling constants of the energy functional. The primary motivation of this work is to test the robustness of such protocols with respect to some of the technical and numerical details of the underlying calculations, especially when the calibration explores a large parameter space. To this end, we quantify the effect of these uncertainties on both the optimization and statistical emulation of composite objective functions. We also emphasize that Bayesian calibration can provide better estimates of the theoretical errors used to define objective functions.

description: Recent experiments on two-dimensional (2D) electron systems have found a sharp increase in the effective mass of electrons with decreasing electron density. In an effort to understand this behavior we employ the many-body theory to calculate the quasiparticle effective mass in 2D electron systems. Because the low density regime is explored in the experiments we use the $GWΓ$ approximation where the vertex correction $Γ$ describes the correlation effects to calculate the self-energy from which the effective mass is obtained. We find that the quasiparticle effective mass shows a sharp increase with decreasing electron density. Disorder effects due to charged impurity scattering plays a crucial role in density dependence of effective mass.

description: The formal definition of limit is one mathematical idea that gives difficulties to most students. Therefore, it is necessary to provide engaging activity in order to construct the students' understanding about the definition. This study aims to shed light on designing activities with dynamic geometry software to facilitate the students in discovering the formal definition of limit. Forty-eight students participated in the study. Both quantitative and qualitative data were collected from the students' responses in and attitudes toward the activities. The students' responses were gathered directly by using the dynamic geometry software whereas an online questionnaire was used to collect the students' attitudes. The results of the study then presented in this paper. Further, a set of suggestions in designing and implementing dynamic geometry environments to foster students' understanding about formal definition of limit was also proposed.

description: Due to delays in the adaptation of production or delivery rates, supply chains can be dynamically unstable with respect to perturbations in the consumption rate, which is known as "bull-whip effect". Here, we study several conceivable production strategies to stabilize supply chains, which is expressed by different specifications of the management function controlling the production speed in dependence of the stock levels. In particular, we will investigate, whether the reaction to stock levels of other producers or suppliers has a stabilizing effect. We will also demonstrate that the anticipation of future stock levels can stabilize the supply system, given the forecast horizon is long enough. To show this, we derive linear stability conditions and carry out simulations for different control strategies. The results indicate that the linear stability analysis is a helpful tool for the judgement of the stabilization effect, although unexpected deviations can occur in the non-linear regime. There are also signs of phase transitions and chaotic behavior, but this remains to be investigated more thoroughly in the future.

The N-th power (N>1) of the differential of this graded q-differential algebra is equal to zero. We use our approach to construct the graded q-differential algebra in the case of a reduced quantum plane which can be endowed with a structure of a graded algebra. We consider the differential d satisfying d to power N equals zero as an analog of an exterior differential and study the first order differential calculus induced by this differential.

description: In this work we present a general machine learning based scheme to optimize experimental control. The method utilizes the neural network to learn the relation between the control parameters and the control goal, with which the optimal control parameters can be obtained. The main challenge of this approach is that the labeled data obtained from experiments are not abundant. The central idea of our scheme is to use the active learning to overcome this difficulty. As a demonstration example, we apply our method to control evaporative cooling experiments in cold atoms. We have first tested our method with simulated data and then applied our method to real experiments. We demonstrate that our method can successfully reach the best performance within hundreds of experimental runs. Our method does not require knowledge of the experimental system as a prior and is universal for experimental control in different systems.

description: The present study is a continuation of a previous one on "hyperelliptic" axisymmetric equilibria started in [Tasso and Throumoulopoulos, Phys. Plasmas 5, 2378 (1998)]. Specifically, some equilibria with incompressible flow nonaligned with the magnetic field and restricted by appropriate side conditions like "isothermal" magnetic surfaces, "isodynamicity" or P + B^2/2 constant on magnetic surfaces are found to be reducible to elliptic integrals. The third class recovers recent equilibria found in [Schief, Phys. Plasmas 10, 2677 (2003)]. In contrast to field aligned flows, all solutions found here have nonzero toroidal magnetic field on and elliptic surfaces near the magnetic axis.

description: Перед агропромышленным комплексом Казахстана стоят кардинальные задачи по устойчивому развитию и наращиванию сельскохозяйственного производства, увеличению выпуска экспортоориентированной, конкурентоспособной продукции и обеспечению продовольственной безопасности страны. Сегодня для решения поставленных задач перед АПК страны принята Государственная программа развития АПК на 2017–2021 годы и внедряются в производство новые Законы «О сельскохозяйственных кооперативах», «О пастбищах» и др. Особое внимание в этих документах уделяется созданию крупных товарных хозяйств на основе кооперации. Анализ современного состояния развития сельского хозяйства в республике показал, что мелкие крестьянские хозяйства, состоящие из одной семьи или из группы людей, слабо оснащенные материально-техническими средствами, в одиночестве без объединений общих сил не в состоянии вести расширенное производство и установить межотраслевые связи в процессе производства и переработки. Эти хозяйства не в состоянии самостоятельно решать проблемы повышения конкурентоспособности производимой ими продукции, внедрения инноваций, поставок безопасных для здоровья населения продуктов питания и лишены возможности получать услуги высококвалифицированных специалистов. Основными сдерживающими факторами развития кооперативного движения в республике являются недостаточные меры государственной поддержки сельского хозяйства, кадрового обеспечения, несовершенство правого законодательства, налогообложения и отсутствие механизмов организации взаимоотношений внутри кооператива. Для реализации поставленных выше задач перед АПК страны, необходимо объединить мелкие крестьянские хозяйства в крупные сельскохозяйственные кооперативы по производству, переработке, хранению, транспортировке и сбыту сельскохозяйственной продукции.

description: В условиях развития глобального экономического кризиса проблемы занятости населения, безработицы и мобильности трудовых ресурсов в Казахстане приобретают все большую актуальность и всегда находятся в центре внимания научной, общественной, политической и хозяйственной деятельности соответствующих ведомств, организаций и предприятий. В кризисный период в целях защиты граждан от безработицы государством была разработана стратегия, которую можно условно охарактеризовать, как «стратегия выживания». Данная стратегия направлена на реализацию государственных программ: создания социальных рабочих мест, переобучения и переподготовки специалистов, и организации молодежной практики. В исследовании проводилось интервью с работниками акиматов, сельскохозяйственных ведомств, сельскими предпринимателями и представителями несельскохозяйственного бизнеса в Южно-Казахстанской области (ЮКО). Основными направлениями развития несельскохозяйственного бизнеса в сельской местности ЮКО являются переработка сельскохозяйственного сырья и продукции, торговозакупочная деятельность, общественное питание в сельских населенных пунктах (придорожные магазины и кафе) и их бытовое обслуживание, строительство жилых и производственных построек, производство товаров народных промыслов, транспортные услуги. Развитие несельскохозяйственного бизнеса на селе будет содействовать диверсификации хозяйственной деятельности в сельской экономике, расширению источников формирования доходной базы местных бюджетов, повышению устойчивости развития сельских территорий в части расширения масштабов занятости и развития самозанятости сельского населения, а также повышению уровня его жизни.

description: We studied the computational properties of an attractor neural network (ANN) with different network topologies. Though fully connected neural networks exhibit, in general, a good performance, they are biologically unrealistic, as it is unlikely that natural evolution leads to such a large connectivity. We demonstrate that, at finite temperature, the capacity to store and retrieve binary patterns is higher for ANN with scale--free (SF) topology than for highly random--diluted Hopfield networks with the same number of synapses. We also show that, at zero temperature, the relative performance of the SF network increases with increasing values of the distribution power-law exponent. Some consequences and possible applications of our findings are discussed.

description: Additive manufacturing (AM) of components using material extrusion (MEX) offers the potential for the integration of functions through the use of multi-material design, particularly through the use of electrically conductive composites in the design of sensors, actuators, and electrical connections. However, there is a significant gap in the availability of electrical composite properties, which is essential for informed design in mechatronic product development. This study addresses this gap by systematically evaluating the resistivity of 14 commercially available filaments as unprocessed feedstock, extruded fibers, and fabricated MEX-structures. The analysis of the MEX-structures considers the impact of anisotropic electrical properties induced by the path planning inherent to AM. The results demonstrate that composites containing fillers with a high aspect ratio, such as carbon nanotubes (CNT) and graphene, significantly enhance conductivity and improve the reproducibility of MEX structures. Notably, the extrusion of filaments into MEX structures generally led to an increase in resistivity; however, composites with CNT or graphene exhibited less reduction in conductivity and lower variability compared to those containing only carbon black (CB) or graphite. These findings underscore the importance of filler selection and composition in optimizing the electrical performance of MEX structures.
title: Exploring the Impact of the Glory and Dismay Football Literacies Programme on Hard-to-Reach Adult Learners
Creators: name: Player, John
Publisher: name: The Open University
Year: 2010

description: This thesis aims to contribute to the field of New Literacy Studies by giving voice to the experience of learners involved in a situated pedagogy, namely the Glory and Dismay Football Literacy Programme (GDFLP). This programme evinces the view that reluctant adult learners will engage in literacy learning programmes if such programmes have a direct bearing on learners' interests, concerns and lives. The thesis describes the nature of the specific GDFLP programme and explores the impact of this programme on learners' lives and literacy practices. As the coordinator and a tutor on the GDFLP, this thesis also reflects some of the complexity I experienced in managing a combined teacher and academic researcher positioning. My key research question is 'what are the learners' experiences of the GDFLP?', underpinned by a set of sub questions including one which is at the centre of much debate around literacy teaching, that is, 'what is the impact of the GDFLP on adult learners' functional and critical literacy acquisition?' To answer these research questions I adopt a qualitative case study approach. Primary data includes semi-structured interviews and participant observations recorded over a period of 12 weeks. Secondary data includes existing material generated by the GDFLP. The key findings presented in the thesis are in the form of six case studies at the centre of which are learners' narratives about their learning and literacy experiences and which are complemented by understandings drawn from my participant observations and engagement with academic literature. The representational aim is to 'give voice' to the learners' educational and literacy journey, particularly their engagement with the GDFLP. I draw on critical discourse analysis, literacy studies and some aspects of narrative analysis and sociolinguistics. The case study approach provides a framework to explore how learners are subjected to a discursive formation that suffuses working-class Scottish football culture. This thesis explores how learners are made 'subjects', investigating how learners 'partially consent' to the interests of others with much more power. As an educator working for Community Learning and Development, City of Edinburgh Council with the Adult Learning Project (ALP) in Edinburgh, influenced by Paulo Freire, I examine how critical literacy pedagogy, enacted in the GDFLP, seeks to and succeeds in addressing such inequities. This thesis is motivated by a desire to do something about the structural inequalities to which the learners are subjected and to provide academic evidence for the social practice approach to adult literacy teaching currently advocated by the Scottish Government.
Perspective: Strongly correlated and topological states in [111] grown transition metal oxide thin films and heterostructures

description: We highlight recent advances in the theory, materials fabrication, and experimental characterization of strongly correlated and topological states in [111] oriented transition metal oxide thin films and heterostructures, which are notoriously difficult to realize compared to their [001] oriented counterparts. We focus on two classes of complex oxides, with the chemical formula ABO3 and A2B2O7, where the B sites are occupied by an open-shell transition metal ion with a local moment, and the A sites are typically a rare earth. The [111] oriented quasi-two-dimensional lattices derived from these parent compound lattices can exhibit peculiar geometries and symmetries, namely, a buckled honeycomb lattice, as well as kagome and triangular lattices. These lattice motifs form the basis for emergent strongly correlated and topological states expressed in exotic magnetism, various forms of orbital ordering, topological insulators, topological semimetals, quantum anomalous Hall insulators, and quantum spin liquids. For transition metal ions with high atomic number, spin-orbit coupling plays a significant role and may give rise to additional topological features in the electronic band structure and in the spectrum of magnetic excitations. We conclude the Perspective by articulating open challenges and opportunities in this actively developing field.

The Fermi surface we observe is essentially that expected of nearly-free electrons - establishing Ag5Pb2O6 as the first known example of a monovalent, nearly-free electron superconductor at ambient pressure.

description: Detecting and modelling the reprocessed hard X-ray emission component in the accretion flow, so-called reflection spectrum is a main tool to estimate black hole spins in a wide range of astrophysical black holes regardless of their mass or distance. In this work, we studied the X-ray spectra of the Seyfert I galaxy III Zw 2 using multi-epoch XMM-Newton, NuSTAR and Suzaku observations. The X-ray spectra exhibit a soft-excess below 1 keV and a prominent excess at the location of the broad Fe Kα line at 6.4 keV. To account for these spectral features, we have fitted the spectra with multiple models including an ionized partially covering absorber and an accretion disk reflection model. To fully resolve the reflection component, we analyzed jointly the XMM-Newton and NuSTAR observations taken in 2017 and archival XMM-Newton data from 2000. Assuming the reflection scenario, the resulting model fits support a rapidly spinning black hole (a > 0.98) in this radio-intermediate source. The X-ray spectra in 2000 and 2017 are remarkably similar with the only difference in the reflection fraction, possibly due to a change in the geometry of the accretion flow. However, the Suzaku observation is markedly different, and we suggest this could be an effect of a jet contribution in the X-ray band, which is supported by the elevated radio flux during this observation.

description: Liquid scintillator (LS) is widely used in various neutrino oscillation experiments, in particular, the reactor neutrino experiments. The complex absorption and re-emission processes of optical photons are known to be an important source of the non-linear and non-uniform response of LS detectors. Precise simulation of light propagation in LS is highly desirable to model the detector response and reduce the systematic errors. In this paper, we develop a novel optical model which can completely deal with the competitive photon absorption and subsequent re-emission processes of the LS components. It allows to directly plug in the laboratory measurements of the LS components to model any LS composition. Extensive measurements have been performed to obtain the essential optical parameters for this model. We validate the model with a bench-top experiment featuring a small LS volume. Furthermore, we demonstrate that for any given detector geometry, this model provides the capability of optimizing the LS recipe to maximize the light collection. It is valuable for designing future LS-based detectors and improving the agreement between Monte Carlo and data for current neutrino experiments.

title: Ultracold Rydberg Atoms

description: This thesis presents a new experimental facility that has been developed in the course of the PhD of the author together with the experimental measurements of the dipole moments for transitions between 5P3/2 and nD5/2 states in Rb atoms, where 20 ≤ n ≤ 48. A laser cooling setup for rubidium atoms was designed and built that allows to produce 3 x 10 atoms at temperature of few microkelvins. A laser system for coherent excitation to Rydberg states was realised that exploits a two-photon ladder excitation scheme. Such setup allowed to directly measure transition dipole moments from the first excited state to high n Rydberg states. The electromagnetically induced transparency and Autler-Townes splitting phenomena were exploited in order to obtain the values of the dipole moments, which were found to be in an excellent agreement with the theoretical values calculated using the quasiclassical approach by our collaborators in Novosibirsk. To the author's knowledge, these are the first direct measurements of such dipole moments. The data shown in the thesis proves the reliability of the measurement method. The obtained results are extremely useful to validate theoretical models and gain insight in the physics of the interactions that will be an object of subsequent studies. The methods presented in the dissertation will be used in the future to detect in a non-destructive way Rydberg-Rydberg interactions within mesoscopic samples.

description: We studied Zn-substitution effect on the high-T_c superconductors, underdoped La_{2-x}Sr_xCu_{1-y}Zn_yO_4 (x=0.10; y=0, 0.01, 0.02), optimally doped (x=0.15; y=0, 0.02), and overdoped (x=0.20; y=0, 0.03, 0.06) in a temperature range of T=4.2-300 K, using Cu nuclear quadrupole resonance (NQR) spin-echo technique. We found full disappearance of the Cu NQR signals for the Zn-substituted, Sr-underdoped x=0.10 samples below about 40 K, partial disappearance for the Sr-optimally doped ones below about 50 K, but not for the overdoped x=0.20 ones. From the Zn-doping, the Sr-doping and the temperature dependence of the wipeout effect, we associate the wipeout effect with Zn-induced Curie magnetism or its extended glassy charge-spin stripe formation.

A simple way for students to visualize cellular respiration : Adapting the board game MousetrapTM to model complexity

description: Lecture-based introductory biology courses are typically content-heavy as instructors strive to provide students with foundational knowledge in a broad range of topics. One topic traditionally covered is cellular respiration, the series of enzymatic reactions that results in the formation of ATP, the energy currency in cells, from carbohydrates. Cellular respiration is often difficult for students in these classes because the topic is both complex and ‘invisible’ – the students can’t observe the process. In an attempt to overcome these difficulties and enhance student learning, we describe how the board game Mousetrap™ (Hasbro, Milton Bradley) can be adapted to model cellular respiration. Mousetrap™ is ideal for this adaptation due to its 3-dimensionality, the necessary assembly of its 3D components and the interdependence of its 3D components. In the classroom, the pieces of the game are re-assigned into the three stages of cellular respiration (glycolysis, Krebs Cycle, electron transport chain); after each stage is discussed in lecture, students assemble that part of the board game. By the end of class, the game is completely assembled, providing students with a workable model of the entire cellular respiration pathway. Students then trigger the mousetrap to visualize the complete, dynamic process and ‘make ATP’ (i.e., catch the mouse). Mousetrap™ serves as a dynamic, interactive, active learning tool that helps students build a basic, but accurate model for cellular respiration that can be used as a scaffold for subsequent upper-level courses or for more complex discussions related to fermentation, toxicology, and/or enzymatic regulation.

description: Bryophyte flora of Kosovo is underexplored. The number of taxa reported is still very low compared with the neighboring countries from one side, and the presence of two important mountain massifs in Kosovo (Bjeshkët e Nemuna/Prokletije and Shar/Šar Mountains) from the other side. Bjeshkët e Nemuna (BN) is made up of many large mountains located in three different countries (Albania, Kosovo and Montenegro) of the Balkan Peninsula. The knowledge of bryoflora of BN is better known for Albania and Montenegro, with recent publications for both countries, whereas there is only one publication for Kosovo. In this context, the results from two field trips (in 2015 and 2019) carried on in various localities (Lagjia e Kaprojve, Reka e Allagës, Liqenat, Bogë and Hajla) in the BN Mountains are presented here. Altogether, 1140 moss specimens were examined, which comprise about 130 taxa. Thirteen species are new records for Kosovo: Calliergonella lindbergii, Campyliadelphus chrysophyllus, Cyrtomnium hymenophylloides, Dialytrichia mucronata, Dicranella varia, Grimmia anodon, G, donniana, Hypnum andoi, Pleuridium acuminatum, Polytrichum strictum, Schistidium helveticum, S. rivulare and Sphagnum centrale. In addition, two taxa are new at the variety level: Hedwigia ciliata var. leucophaea and Syntrichia ruralis var. ruraliformes. Several species have conservation value in the European context; they are red-list candidate species: Brachythecium geheebii, Encalypta affinis, Racomitrium ericoides, Schistidium papillosum, S. helveticum and Sphagnum centrale.

description: Background and Aim: Mutans streptococci are the main cause of tooth decay. Application of natural materials as mouthwash has been effective in reducing the bacterial count. This study aimed to assess the antimicrobial effects of rose water and pomegranate vinegar in comparison with Persica mouthwash on two oral bacteria responsible for tooth decay.Materials and Methods: Strongly adherent strains of Streptococcus mutans and Streptococcus sobrinus were selected for this in vitro study. Antimicrobial effects ofpomegranate vinegar and rose water on microbial count in the biofilm and adhesion potential of bacteria were evaluated by microtiter plate method. Also, the well-platetechnique was used to assess the effect of rose water and pomegranate vinegar in comparison with Persica mouthwash on bacterial growth and proliferation. The obtained resulted were analyzed by one-way ANOVA and Tukey’s post hoc test using Graph Pad Prism version 5 software. Level of significance was set at P=0.05 with 95% confidence interval.Results: Pomegranate vinegar, rose water and Persica decreased plaque formation by S. mutans by 93%, 80% and 68%, respectively. These values for the S. sobrinus were 92%, 57% and 48%, respectively (all Ps<0.001). Pomegranate vinegar was more effective than the other two materials (P<0.001). However, none of these materials eliminated the biofilm. Pomegranate vinegar and Persica mouthwash inhibited the growth of the afore-mentioned bacteria.Conclusion: Within the limitations of this study, it seems that pomegranate vinegar and rose water have the potential to prevent or control the proliferation of S. mutans and S.sobrinus.

description: Black-box neural network models are widely used in industry and science, yet are hard to understand and interpret. Recently, the attention mechanism was introduced, offering insights into the inner workings of neural language models. This paper explores the use of attention-based neural networks mechanism for estimating feature importance, as means for explaining the models learned from propositional (tabular) data. Feature importance estimates, assessed by the proposed Self-Attention Network (SAN) architecture, are compared with the established ReliefF, Mutual Information and Random Forest-based estimates, which are widely used in practice for model interpretation. For the first time we conduct scale-free comparisons of feature importance estimates across algorithms on ten real and synthetic data sets to study the similarities and differences of the resulting feature importance estimates, showing that SANs identify similar high-ranked features as the other methods. We demonstrate that SANs identify feature interactions which in some cases yield better predictive performance than the baselines, suggesting that attention extends beyond interactions of just a few key features and detects larger feature subsets relevant for the considered learning task.
