description: We present a first-principles framework to investigate the electron scattering channels and transport properties for polar material by combining the exact solution of linearized electron-phonon (e-ph) Boltzmann transport equation in its integral-differential form associated with the e-ph coupling matrices obtained from polar Wannier interpolation scheme. No ad hoc parameter is required throughout this calculation, and GaAs, a well-studied polar material, is used as an example to demonstrate this method. In this work, the long-range and short-range contributions as well as the intravalley and intervalley transitions in the e-ph interactions (EPIs) have been quantitatively addressed. Promoted by such mode-by-mode analysis, we find that in GaAs, the piezoelectric scattering is comparable to deformation-potential scattering for electron scatterings by acoustic phonons in EPI even at room temperature and makes a significant contribution to mobility. Furthermore, we achieved good agreements with experimental data for the mobility, and identified that electrons with mean free paths between 130 and 210 nm contribute dominantly to the electron transport at 300 K. Such information provides deeper understandings on the electron transport in GaAs, and the presented framework can be readily applied to other polar materials.

description: This work analyses the dynamical properties of periodically-driven band models. Focusing on the case of Bose-Einstein condensates, and using a meanfield approach to treat inter-particle collisions, we identify the origin of dynamical instabilities arising due to the interplay between the external drive and interactions. We present a widely-applicable generic numerical method to extract instability rates, and link parametric instabilities to uncontrolled energy absorption at short times. Based on the existence of parametric resonances, we then develop an analytical approach within Bogoliubov theory, which quantitatively captures the instability rates of the system, and provides an intuitive picture of the relevant physical processes, including an understanding of how transverse modes affect the formation of parametric instabilities. Importantly, our calculations demonstrate an agreement between the instability rates determined from numerical simulations, and those predicted by theory. To determine the validity regime of the meanfield analysis, we compare the latter to the weakly-coupled conserving approximation. The tools developed and the results obtained in this work are directly relevant to present-day ultracold-atom experiments based on shaken optical lattices, and are expected to provide an insightful guidance in the quest for Floquet engineering.

description: This paper investigates a pursuit-evasion game with a single pursuer and evader in a bounded environment, inspired by observations of predation attempts by lionfish (Pterois sp.). The pursuer tracks the evader with a pure pursuit strategy while using an additional bioinspired tactic to trap the evader, i.e. minimize the evader’s escape routes. Specifically, the pursuer employs symmetric appendages inspired by the large pectoral fins of lionfish, but this expansion increases its drag and therefore its work to capture the evader. The evader employs a bioinspired randomly-directed escape strategy to avoid capture and collisions with the boundary. Here we investigate the trade-off between minimizing the work to capture the evader and minimizing the evader’s escape routes. By using the pursuer’s expected work to capture as a cost function, we determine when the pursuer should expand its appendages as a function of the relative distance to the evader and the evader’s proximity to the boundary. Visualizing the pursuer’s expected work to capture everywhere in the bounded domain, yields additional insights about optimal pursuit trajectories and illustrates the role of the boundary in predator-prey interactions.

description: The charged particle multiplicity ($n_{ch}$) and pseudorapidity density $(dn_{ch}/dη)$ are key observables to characterize the properties of matter created in heavy ion collisions. The dependence of these observables on collision energy and the collision geometry are a key tool to understand the underlying particle production mechanism. Recently a lot of focus has been made on asymmetric and deformed nuclei collisions since these collisions can provide a deeper understanding about the nature of quantum chromodynamics (QCD). On phenomenological perspective a unified model which describes the experimental data coming from various kind of collision experiments, is much needed to provide the physical insights about the production mechanism. In this paper, we have calculated the charged hadron multiplicities for nucleon-nucleus (such as proton-lead $(p-Pb)$ and asymmetric nuclei collisions like deutron-gold $(d-Au)$, and copper-gold $(Cu-Au)$ within a new version of wounded quark model (WQM) and shown their variation with respect to centrality. Further we have used a suitable density function within our WQM to calculate pseudorapidity density of charged hadrons at mid-rapidity in the collisions of deformed uranium nuclei. We found that our model with suitable density functions describes the experimental data for symmetric, asymmetric and deformed nuclei collisions simultaneously over a wide range of collision energy.

The added value of speech technology in clinical care of patients with dysarthria

description: Adults with dysarthria frequently face social, psychological, and daily communication problems, negatively impacting their well-being. Therefore, they should have access to an early diagnosis and therapy. Through decades, acoustic data has potentially been used for objective evaluations of speech disorders, providing scientific and engineering insight. Considering the adverse effects of disordered articulation and prosody on communication and quality of life, the overall aim of this thesis is to contribute to the clinical care and well-being of patients with dysarthria through the development of signal-processing techniques and speech technology in general. This research increases the existing knowledge about behavioural treatments of articulation in this population and extends the understanding of prosodic mechanisms and strategies through emerging techniques which include acoustically based methods. Concerning articulation, a clinically valuable set of exercises has been developed for direct and intensive therapy according to the principles of motor learning for speech rehabilitation. Also, a comprehensive and hierarchically structured training method for articulation has been designed. The intensive articulation therapy based on this methodology has proven to be feasible and effective for improving speech intelligibility in subjects with chronic or progressive dysarthria. The methodology and exercise material were incorporated into a Virtual Articulation Therapist (VAT), which also includes visual and auditory cues of the target utterance and provides adequate and relevant feedback to end users. The VAT offers clear applicability in the medical management of patients with dysarthria, is well accepted by end-users and has an added value for the current Flemish healthcare situation. Concerning prosody, a new acoustically-based multidimensional approach has been developed for the objective assessment and more comprehensive characterization of sentence accent in atypical prosody of speakers with dysarthria. The clinically usable set of newly detected acoustic features correlating with accent, combines different measures of F0, intensity and duration within an utterance. The developed automatic algorithm can accurately predict accented and unaccented syllables in healthy and dysarthric speech of Germanic languages like English and Dutch comparable in accentuation patterns. A cross-population study validates the detailed set of acoustic descriptors of accent production, which shows high reliability. In addition, it provides an objective description of the strategies used for accentuation across different severities of the speech impairment. The introduced speech technology provides the speech therapist with an objective and automatic measure of sentence accent, supporting the understanding of atypical prosody production and helping make informed clinical decisions and select more tailored therapy approaches.

description: We study closed photon orbits in spherically-symmetric static solutions of supergravity theories, a Horndeski theory, and a theory of quintessence. These orbits lie in what we shall call a photon sphere (anti-photon sphere) if the orbit is unstable (stable). We show that in all the asymptotically flat solutions we examine that admit a regular event horizon, and whose energy-momentum tensor satisfies the strong energy condition, there is one and only one photon sphere outside the event horizon. We give an example of a Horndeski theory black hole (whose energy-momentum tensor violates the strong energy condition) whose metric admits both a photon sphere and an anti-photon sphere. The uniqueness and non-existence also holds for asymptotically anti-de Sitter solutions in gauged supergravity. The latter also exhibit the projective symmetry that was first discovered for the Schwarzschild-de Sitter metrics: the unparameterised null geodesics are the same as when the cosmological or gauge coupling constant vanishes. We also study the closely related problem of accretion flows by perfect fluids in these metrics. For a radiation fluid, Bondi's sonic horizon coincides with the photon sphere. For a general polytropic equation of state this is not the case. Finally we exhibit counterexamples to a conjecture of Hod's.

description: Most studies of disease spreading consider the underlying social network as obtained without the contagion, though epidemic influences people's willingness to contact others: A "friendly" contact may be turned to "unfriendly" to avoid infection. We study the susceptible-infected disease-spreading model on signed networks, in which each edge is associated with a positive or negative sign representing the friendly or unfriendly relation between its end nodes. In a signed network, according to Heider's theory, edge signs evolve such that finally a state of structural balance is achieved, corresponding to no frustration in physics terms. However, the danger of infection affects the evolution of its edge signs. To describe the coupled problem of the sign evolution and disease spreading, we generalize the notion of structural balance by taking into account the state of the nodes. We introduce an energy function and carry out Monte Carlo simulations on complete networks to test the energy landscape, where we find local minima corresponding to the so-called jammed states. We study the effect of the ratio of initial friendly to unfriendly connections on the propagation of disease. The steady state can be balanced or a jammed state such that a coexistence occurs between susceptible and infected nodes in the system.

description: Caloric cooling enlisting solid-state refrigerants is potentially a promising eco-friendly alternative to conventional cooling based on vapor compression. The most common refrigerant materials for elastocaloric cooling to date are Ni-Ti based superelastic shape memory alloys. Here, we have explored tuning the operation temperature range of Ni50.8Ti49.2 for elastocaloric cooling. In particular, we have studied the effect of thermal treatments (a.k.a. aging) on the transformation temperature, superelasticity, and elastocaloric effects of Ni50.8Ti49.2 shape memory alloy tubes. The isothermal compressive test revealed that the residual strain of thermally-treated Ni-Ti tubes at room temperature approaches zero as aging time is increased. Short-time aging treatment at 400 ◦C resulted in good superelasticity and elastocaloric cooling performance with a large tunable austenite finish (Af) temperature range of 24.7 ◦C, as determined from the Af temperature of the samples that were aged 5–120 min. The main reason of the property change is the formation of a different amount of Ni4Ti3 precipitates in the NiTi matrix. Our findings show that it is possible to tailor the Af temperature range for development of cascade elastocaloric cooling systems by thermally treating a starting single composition Ni-Ti alloy.

description: The advent of abundant on-board sensors and electronic devices in vehicles populates the paradigm of participatory sensing to harness crowd-sourced data gathering for intelligent transportation applications, such as distance-to-empty prediction and eco-routing. While participatory sensing can provide diverse driving data, there lacks a systematic study of effective utilization of the data for personalized prediction. There are considerable challenges on how to interpolate the missing data from a sparse dataset, which often arises from participatory sensing. This paper presents and compares various approaches for personalized vehicle energy consumption prediction, including a blackbox framework that identifies driver/vehicle/environment-dependent factors and a collaborative filtering approach based on matrix factorization. Furthermore, a case study of distance-to-empty prediction for electric vehicles by participatory sensing data is conducted and evaluated empirically, which shows that our approaches can significantly improve the prediction accuracy.

title: Efficacy Appeals in the High-Stakes Classroom: Re-Examining Teachers' use of Test Preparation Strategies
Creators: name: Wilkinson, H
Publisher: name: Liverpool John Moores University

description: The ways in which teachers communicate to students about exams has been found to have a significant impact on student outcomes such as student engagement and motivation, and academic performance. However, research has predominantly centred on the use of communications which highlight the negative consequences of failure in order to motivate students. The present research begins by exploring the variety of ways in which teachers communicate to students about exams through observational analysis of 30 lessons with students undertaking the GCSE syllabus. Findings from this initial study led to the focus on the use of teachers’ efficacy communications; namely statements from teachers which provide students with an action to follow which will help them to achieve their target grade. Study Two presents the theoretical development of this concept, and the creation of a questionnaire to measure this phenomenon: the Teacher’s use of Efficacy Appeals in the Classroom prior to High-stakes Exams (TEACHE). Cognitive pre-testing is utilised, and the reliability and validity of data obtained from the TEACHE is explored through data collected from 236 Year 10 students. The refinement of the TEACHE following these processes is documented. Study Three deploys multi-level structural equation modelling with data collected from 1062 Year 10 students from seven schools in the North of England to explore how fear and efficacy appeals used by teachers are appraised by students and how this impacts students’ levels of engagement. Students’ views of their relationship with their teacher and how this relates to fear and efficacy appraisal and engagement are also explored. Students’ appraisal of fear and efficacy communications were found to relate to aspects of their engagement. Students’ levels of self-efficacy and response efficacy relating to efficacy appeal communications were found to impact their engagement, however frequency of these communication was not found to significantly impact; indicating a similar appraisal-based model of efficacy appeals as seen in the fear appeal literature. Teacher-student relationship was not found to have a moderating role between either fear or efficacy appeals and student engagement. Class-level effects were observed in relation to fear appeal communications, but not efficacy appeals or teacher-student relationships. Two significant cross-level interactions were identified when exploring class-level fear appeal frequency, but none for efficacy appeals. Results are discussed in line with previous literature. Limitations of the research are considered along with practical implications for teachers and educators, and considerations for future research.

description: A key challenge encountered by printed electronics is that the conductivity of sintered metal nanoparticle (NP) traces is always several times smaller than the bulk metal conductivity. Identifying the relative roles of the voids and the residual polymers on NP surfaces in sintered NP traces, in determining such reduced conductivity, is essential. In this paper, we employ a combination of electron microscopy imaging and detailed simulations to quantify the relative roles of such voids and residual polymers in the conductivity of sintered traces of a commercial (Novacentrix) silver nanoparticle-based ink. High resolution transmission electron microscopy imaging revealed details of the morphology of the inks before and after being sintered at 150 °C. Prior to sintering, NPs were randomly close packed into aggregates with nanometer thick polymer layers in the interstices. The 2D porosity in the aggregates prior to sintering was near 20%. After heating at 150 °C, NPs sintered together into dense aggregates (nanoaggregates or NAgs) with sizes ranging from 100 to 500 nm and the 2D porosity decreased to near 10%. Within the NAgs, the NPs were mostly connected via sintered metal bridges, while the outer surfaces of the NAgs were coated with a nanometer thick layer of polymer. Motivated by these experimental results, we developed a computational model for calculating the effective conductivity of the ink deposit represented by a prototypical NAg consisting of NPs connected by metallic bonds and having a polymer layer on its outer surface placed in a surrounding medium. The calculations reveal that a NAg that is 35%–40% covered by a nanometer thick polymeric layer has a similar conductivity compared to prior experimental measurements. The findings also demonstrate that the conductivity is less influenced by the polymer layer thickness or the absolute value of the NAg dimensions. Most importantly, we are able to infer that the reduced value of the conductivity of the sintered traces is less dependent on the void fraction and is primarily attributed to the incomplete removal of the polymeric material even after sintering.

description: During the Covid-19 pandemic, Sweden soon found itself alone and heavily criticised for its internationally deviant strategy. Why did this approach nevertheless receive widespread public support in Sweden? This article develops and tests a novel rally around the flag (RRTF) theory, which places national identity centre stage. In contrast to previous work, the article differentiates between national pride, national chauvinism, uncritical patriotism, national attachment, and ethnic nationhood conception – expecting only the first three of these to be related to supporting the Swedish Covid approach. Survey data from a politically representative sample of Swedes support the expectations. It is concluded that the popular support for the ‘Swedish experiment’ is to be understood as an RRTF – although in this case the flag was ‘unwaved’. This suggests that even national identities that draw their pride from institutional rather than cultural superiority lend themselves to RRTF processes.

description: Erwerbsarbeit verändert sich derzeit organisatorisch wie inhaltlich in starkem Maße. Kriterien dafür, was heute gute Arbeit ist, können nicht einfach aus der traditionellen industriellen Arbeit in neue Formen von Dienstleistungs-, Wissens- und freiberuflicher Arbeit übertragen werden. Das vorzustellende Forschungsprojekt ermittelt Merkmale guter Arbeit durch den Vergleich verschiedener Formen von Tätigkeit aus der subjektiven Sicht der Arbeitenden. In einer explorativen Studie wurden mit Hilfe narrativer Grid-Interviews die subjektiven Repräsentationen zum Thema Arbeit bei frei-gemeinnützig (ehrenamtlich) tätigen Menschen untersucht. Dabei wurde die Erfahrung frei-gemeinnütziger Tätigkeit mit den Erfahrungen in anderen Formen der Arbeitstätigkeit kontrastiert. Dabei wurden insbesondere Gemeinsamkeiten und Unterschiede in der Wahrnehmung von freiwilliger Arbeit und Erwerbsarbeit herausgearbeitet. Es zeigt sich, aus welchen subjektiven und biographischen Motiven heraus Menschen einer frei-gemeinnützigen Arbeit nachgehen. Auch das Verhältnis verschiedener Arbeitstätigkeiten zu den Idealvorstellungen von Arbeit ist aufschlussreich und wird dargestellt.

description: We present an efficient implementation of dynamically pruned quantum dynamics, both in coordinate space and in phase space. We combine the ideas behind the biorthogonal von Neumann basis (PvB) with the orthogonalized momentum-symmetrized Gaussians (Weylets) to create a new basis, projected Weylets, that takes the best from both methods. We benchmark pruned dynamics using phase-space-localized PvB, projected Weylets, and coordinate-space-localized DVR bases, with real-world examples in up to six dimensions. We show that coordinate-space localization is most important for efficient pruning and that pruned dynamics is much faster compared to unpruned, exact dynamics. Phase-space localization is useful for more demanding dynamics where many basis functions are required. There, projected Weylets offer a more compact representation than pruned DVR bases.

The author suggests that the palpable anger collectively felt and expressed as a community has propelled a host of social-political actions to dismantle anti-Black systems of oppression, including within academia. She highlights that the scholarship on Black youth development has driven innovations in theory and methodology that have influenced the field of developmental science broadly and recommends future research areas for consideration.

description: BSC is one of the management tools that help an organization to achieve its vision by aligning the organization's strategic goals to every employee's activity. As one of governmental financial institutions, DBE has implemented BSC in 2010. While implementing BSC, the Bank has faced a number of challenges. This study focused on investigating the challenges and prospects that DBE faces in general and the credit process in particular. To collect data interview and questionnaire have been used and the method used is descriptive method. The questionnaires are prepared for 51 credit process employees and 110 bank's credit customers. The interview is for the top management official of the bank who works in credit area and support credit area. Out of the administered questionnaire, only 23 employees and 50 customers managed to return. The results that come out of the questionnaires and interview is analyzed using descriptive method of analysis and presented in the form of tables and graphs. The finding shows that the major challenges that DBE faces is emanated from lack of commitment of top management officials , lack of understanding of the tool, early cascading and considering the tool more as a tool of measurement rather than a tool for strategic management. However; the tool is also helps the organization by increasing the organization performance, by communicating the organization mission, vision and strategic objective to employees, by creating team spirit and others. So to avoid the challenges it is recommended that the Bank should give training about the tool, the Bank should define the measurements, and after being sure that the metrics measure the activities of the business units and the selected measure is easily quantifiable then attaching it with benefits will be wise in order to achieve what is set in the future

description: Individual tree detection (ITD) and crown delineation are two of the most relevant methods for extracting detailed and reliable forest information from LiDAR (Light Detection and Ranging) datasets. However, advanced computational skills and specialized knowledge have been normally required to extract forest information from LiDAR. The development of accessible tools for 3D forest characterization can facilitate rapid assessment by stakeholders lacking a remote sensing background, thus fostering the practical use of LiDAR datasets in forest ecology and conservation. This paper introduces the treetop application, an open-source web-based and R package LiDAR analysis tool for extracting forest structural information at the tree level, including cutting-edge analyses of properties related to forest ecology and management. We provide case studies of how treetop can be used for different ecological applications, within various forest ecosystems. Specifically, treetop was employed to assess post-hurricane disturbance in natural temperate forests, forest homogeneity in industrial forest plantations and the spatial distribution of individual trees in a tropical forest. treetop simplifies the extraction of relevant forest information for forest ecologists and conservationists who may use the tool to easily visualize tree positions and sizes, conduct complex analyses and download results including individual tree lists and figures summarizing forest structural properties. Through this open-source approach, treetop can foster the practical use of LiDAR data among forest conservation and management stakeholders and help ecological researchers to further understand the relationships between forest structure and function.

description: We report studies of the interaction of six acyclic CB[n]-type receptors toward a panel of drugs of abuse by a combination of isothermal titration calorimetry and 1H NMR spectroscopy. Anthracene walled acyclic CB[n] host (M3) displays highest binding affinity toward methamphetamine (Kd=15 nM) and fentanyl (Kd=4 nM). Host M3 is well tolerated by Hep G2 and HEK 293 cells up to 100 μM according to MTS metabolic and adenylate kinase release assays. An in vivo maximum tolerated dose study with Swiss Webster mice showed no adverse effects at the highest dose studied (44.7 mg kg−1). Host M3 is not mutagenic based on the Ames fluctuation test and does not inhibit the hERG ion channel. In vivo efficacy studies showed that pretreatment of mice with M3 significantly reduces the hyperlocomotion after treatment with methamphetamine, but M3 does not function similarly when administered 30 seconds after methamphetamine.
Bias Cancellation in One-Determinant Fixed-Node Diffusion Monte Carlo: Insights from Fermionic Occupation Numbers

description: Accuracy of the fixed-node diffusion Monte Carlo (FN-DMC) depends on the node location of the best available trial state $Ψ_T$. The practical FN-DMC approaches available for large systems rely on compact yet effective $Ψ_T$s containing explicitly correlated single Slater determinant (SD). However, SD nodes may be better suited to one system than to another, which may possibly lead to inaccurate FN-DMC energy differences. It remains a challenge, how to estimate inequivalency or appropriateness of SDs. Here we use the differences of a measure based on Euclidean distance between the natural orbital occupation number (NOON) vector of the Slater determinant (SD) from the exact solution in the NOON vector space, that can be viewed as a measure of SD inequivalency and a measure of the expected degree of nondynamic-correlation-related bias in FN-DMC energy differences. This is explored on a set of small noncovalent complexes and covalent bond breaking of Si$_2$ vs. N$_2$. It turns out that NOON-based measures well reflect the magnitude and sign of the bias present in the data available, thus providing new insights to the nature of bias cancellation in SD FN-DMC energy differences.

General formalism for Fourier based Wave Front Sensing: application to the Pyramid wave front sensors

description: In this article, we compare a set of Wave Front Sensors (WFS) based on Fourier filtering technique. In particular, this study explores the "class of pyramidal WFS" defined as the 4 faces pyramid WFS, all its recent variations (6, 8 faces, the flattened PWFS, etc.) and also some new WFSs as the flattened cone WFS or the 3 faces pyramid WFS. In the first part, we describe such a sensors class thanks to the optical parameters of the Fourier filtering mask and the modulation parameters. In the second part, we use the unified formalism to create a set of performance criteria: size of the signal on the detector, efficiency of incoming flux, sensitivity, linear range and chromaticity. In the third part, we show the influence of the previous optical and modulation parameters on these performance criteria. This exhaustive study allows to know how to optimize the sensor regarding to performance specifications. We show in particular that the number of faces has influence on the number of pixels required to do the wave front sensing but no influence on the sensitivity and linearity range. To modify these criteria, we show that the modulation radius and the apex angle are much more relevant. Moreover we observe that the time spent on edges or faces during a modulation cycle allows to adjust the trade-off between sensitivity and linearity range.

description: We establish two complementarity relations for the relative entropy of coherence in quantum information processing, i.e., quantum dense coding and teleportation. We first give an uncertaintylike expression relating local quantum coherence to the capacity of optimal dense coding for bipartite system. The relation can also be applied to the case of dense coding by using unital memoryless noisy quantum channels. Further, the relation between local quantum coherence and teleportation fidelity for two-qubit system is given.

description: We consider the production of a pseudo-scalar particle $A$ at the LHC, and present accurate theoretical predictions for its inclusive cross section in gluon fusion. The prediction is based on combining fixed-order perturbation theory and all-order threshold resummation. At fixed order we include the exact next-to-next-to-leading order (NNLO) plus an approximate next-to-next-to-next-to-leading order (N$^3$LO$_{\rm A}$) which is based on the recent computation at this order for the scalar case. We then add threshold resummation at next-to-next-to-next-to leading logarithmic accuracy (N$^3$LL$^\prime$). Various forms of threshold resummation are considered, differing by the treatment of subleading terms, allowing a robust estimate of the theoretical uncertainties due to missing higher orders. With particular attention to pseudo-scalar masses of $200$ GeV and $750$ GeV, we also observe that perturbative convergence is much improved when resummation is included. Additionally, results obtained with threshold resummation in direct QCD are compared with analogous results as computed in soft-collinear effective theory, which turn out to be in good agreement. We provide precise predictions for pseudo-scalar inclusive cross section at $13$ TeV LHC for a wide range of masses. The results are available through updated versions of the public codes ggHiggs and TROLL.
