description: Paracrine IL-2 signalling drives the CD8 + T cell expansion and differentiation that allow protection against viral infections, but the underlying molecular events are incompletely understood. Here we show that the transcription factor SRF, a master regulator of cytoskeletal gene expression, is required for effective IL-2 signalling during L. monocytogenes infection. Acting cell-autonomously with its actin-regulated cofactors MRTF-A and MRTF-B, SRF is dispensible for initial TCR-mediated CD8+ T cell proliferation, but is required for sustained IL-2 dependent CD8+ effector T cell expansion, and persistence of memory cells. Following TCR activation, Mrtfab-null CD8+ T cells produce IL-2 normally, but homotypic clustering is impaired both in vitro and in vivo. Expression of cytoskeletal structural and regulatory genes, most notably actins, is defective in Mrtfab-null CD8+ T cells. Activation-induced cell clustering in vitro requires F-actin assembly, and Mrtfab-null cell clusters are small, contain less F-actin, and defective in IL-2 retention. Clustering of Mrtfab-null cells can be partially restored by exogenous actin expression. IL-2 mediated CD8+ T cell proliferation during infection thus depends on the control of cytoskeletal dynamics and actin gene expression by MRTF-SRF signalling.

description: The Cygnus-X star-forming complex is one of the most active regions of low and high mass star formation within 2 kpc of the Sun. Using mid-infrared photometry from the IRAC and MIPS Spitzer Cygnus-X Legacy Survey, we have identified over 1800 protostar candidates. We compare the protostellar luminosity functions of two regions within Cygnus-X: CygX-South and CygX-North. These two clouds show distinctly different morphologies suggestive of dissimilar star-forming environments. We find the luminosity functions of these two regions are statistically different. Furthermore, we compare the luminosity functions of protostars found in regions of high and low stellar density within Cygnus-X and find that the luminosity function in regions of high stellar density is biased to higher luminosities. In total, these observations provide further evidence that the luminosities of protostars depend on their natal environment. We discuss the implications this dependence has for the star formation process.

description: Smart traffic engineering and intelligent transportation services are in increasing demand from governmental authorities to optimize traffic performance and thus reduce energy costs, increase the drivers' safety and comfort, ensure traffic laws enforcement, and detect traffic violations. In this paper, we address this challenge, and we leverage the use of Artificial Intelligence (AI) and Unmanned Aerial Vehicles (UAVs) to develop an AI-integrated video analytics framework, called TAU (Traffic Analysis from UAVs), for automated traffic analytics and understanding. Unlike previous works on traffic video analytics, we propose an automated object detection and tracking pipeline from video processing to advanced traffic understanding using high-resolution UAV images. TAU combines six main contributions. First, it proposes a pre-processing algorithm to adapt the high-resolution UAV image as input to the object detector without lowering the resolution. This ensures an excellent detection accuracy from high-quality features, particularly the small size of detected objects from UAV images. Second, it introduces an algorithm for recalibrating the vehicle coordinates to ensure that vehicles are uniquely identified and tracked across the multiple crops of the same frame. Third, it presents a speed calculation algorithm based on accumulating information from successive frames. Fourth, TAU counts the number of vehicles per traffic zone based on the Ray Tracing algorithm. Fifth, TAU has a fully independent algorithm for crossroad arbitration based on the data gathered from the different zones surrounding it. Sixth, TAU introduces a set of algorithms for extracting twenty-four types of insights from the raw data collected. The code is shared here: https://github.com/bilel-bj/TAU.

description: In this paper, we study the low-energy $d-α$ elastic scattering within the two-body cluster effective field theory (EFT) framework. The importance of the $d(α,α) d$ scattering in the $^6 \textrm{Li} $ production reaction leads us to study this system in an effective way. In the beginning, the scattering amplitudes of each channel are written in a cluster EFT with two-body formalism. Using the effective range expansion analysis for the elastic scattering phase shift of $S$, $P$ and $D$ partial waves, the unknown EFT low-energy coupling constants are determined and the leading and next-to-leading orders EFT results for the phase shift in each channel are presented. To verify the accuracy of the results, we compare experimental phase shift and differential cross section data with obtained results. The accuracy of the EFT results and consistency with the experimental data indicate that the EFT is an effective approach for describing low-energy systems.

description: Die vorliegende Arbeit befasst sich mit der Frage, welche psychosozialen Auswirkungen die COVID19-Pandemie und die zur Eindämmung verordneten Massnahmen auf Einzelpersonen von 25 bis 54 Jahren in der wirtschaftlichen Sozialhilfe haben. Ein Ziel der Sozialen Arbeit ist die berufliche und soziale Integration. Damit dies möglich ist, ist die Gesundheit eines Menschen mit den drei Determinanten bio, psycho und sozial ganzheitlich zu betrachten. Soziale und berufliche Integration ist nur möglich, wenn die Klientel die nötige Unterstützung durch die Professionellen der Sozialen Arbeit erhalten. Mittels Leitfadeninterviews werden sozialhilfebeziehende Personen sowie Professionelle der Sozialen Arbeit in der wirtschaftlichen Sozialhilfe zu Veränderungen in den Beratungen sowie zu Veränderungen im persönlichen Leben der Klientel befragt. Die Interviews werden anhand der zusammenfassenden Inhaltsanalyse ausgewertet. Die Autorin stellt fest, dass die psychosozialen Auswirkungen auf Einzelpersonen in der wirtschaftlichen Sozialhilfe sehr unterschiedlich sind und dass sich der Unterstützungsbedarf im Beratungssetting verändert hat. Die Reaktionen auf die COVID19-Pandemie zeigen von Resignation bis hin zu Verschwörungstheorien alles auf. Grundsätzlich lässt sich aber festhalten, dass die Klientel zufrieden mit den Beratungen im Sozialdienst X sind und die Mehrheit der Klientel keine grossen psychosozialen Auswirkungen, verbunden mit der COVID19-Pandemie, wahrgenommen haben.

description: Energy consumption and energy ananlytics has gained increased focus and consideration in industrial applications especially process lines to upgrade their performance and efficiency in the competitive world. A competent analytics method will be highly advantageous to provide the correct direction of energy saving for an industry. Energy analytics method was introduced into energy consumption time analysis model and is developed in this paper. Energy consumption of a camplate production plant was analysed as a case study. The result shows that energy utilization is dependent on the time of operation of the equipments in the plant. Energy sparing obtained via technical innovation in unit process maybe misplaced due to the expanding time of operation within the plant. Energy loss and the distribution of energy loss in the camplate production plant were analysed and the probable energy saving methods were identified from the results.

description: Background: Microorganisms from multiple taxonomic domains engage in intermicrobial interactions to form communities in all biomes. Even with identical community members, these complex interactions can vary in time, space and due to changes in abiotic factors. The range of in silico, in vitro or in vivo methods used to study these interactions is equally wide, and all of them produce a large amount of data. However, there is no standard to report intermicrobial interactions and a dire need for an open access platform to datasets that support this evidence. Objectives: Improve findability and integration of microbial interactions data by humans and machines by enhancing their description via a set of standardized metadata. Methods: Microbial interaction metadata are specified using the LinkML modeling language to leverage validation capacity and interoperability with published ontologies or existing metadata. Durable hosting is enabled via interconnection to metadata in the knowledge base Wikidata embedded within a user-friendly interface and editing features for both humans and machines. Results: Metadata concerning the interactions themselves, associated community members, their environmental context and evidence methods were formalized by types, expected values, and ontology values where appropriate, to enable comparison between studies. We illustrate this metadata scheme by describing examples of microbial interactions within hosts. Once more microbial interactions are described accordingly, original hypotheses could be drawn and tested by bioinformaticians, network scientists and microbiologists.

description: Radio frequency interference (RFI) is a significant challenge faced by today's radio astronomers. While most past efforts were devoted to cleaning the RFI from the data, we develop a novel method for categorizing and cataloguing RFI for forensic purpose. We present a classifier that categorizes RFI into different types based on features extracted using Principal Component Analysis (PCA) and Fourier analysis. The classifier can identify narrowband non-periodic RFI above 2 sigma, narrowband periodic RFI above 3 sigma, and wideband impulsive RFI above 5 sigma with F1 scores between 0.87 and 0.91 in simulation. This classifier could be used to identify the sources of RFI as well as to clean RFI contamination (particularly in pulsar search). In the long-term analysis of the categorized RFI, we found a special type of drifting periodic RFI that is detrimental to pulsar search. We also found evidences of an increased rate of impulsive RFI when the telescope is pointing toward the cities. These results demonstrate this classifier's potential as a forensic tool for RFI environment monitoring of radio telescopes.

Fluctuations and correlations in nonequilibrium systems

description: Nonequilibrium systems exchange the energy with an environment in the form of work and heat. The work done on a system obeys the fluctuation theorem, while the dissipated heat which differs from the work by the internal energy change does not. We derive the modified fluctuation relation for the heat in the overdamped Langevin system. It shows that mutual correlations among the work, the heat, and the internal energy change are responsible for the different fluctuation property of the work and the heat. The mutual correlation is investigated in detail in a two-dimensional linear diffusion system. We develop an analytic method which allows one to calculate the large deviation function for the joint probability distributions. We find that the heat and the internal energy change have a negative correlation, which explains the reason for the breakdown of the fluctuation theorem for the heat.

description: We present a technique for measuring radio-frequency (RF) electric field strengths with sub-wavelength resolution. We use Rydberg states of rubidium atoms to probe the RF field. The RF field causes an energy splitting of the Rydberg states via the Autler-Townes effect, and we detect the splitting via electromagnetically induced transparency (EIT). We use this technique to measure the electric field distribution inside a glass cylinder with applied RF fields at 17.04 GHz and 104.77 GHz. We achieve a spatial resolution of $\bf{\approx}$100 $\bfμ$m, limited by the widths of the laser beams utilized for the EIT spectroscopy. We numerically simulate the fields in the glass cylinder and find good agreement with the measured fields. Our results suggest that this technique could be applied to image fields on a small spatial scale over a large range of frequencies, up into the sub-THz regime.

description: An experiment was conducted during April to July in 2015 at Jawe and Kerekicho Kebeles in SNNP. The aim was to measure ETc, Kc of Desho grass and oats and vetch fodder crops; and to evaluate the WFD (scheduling tool) in terms of biomass yield and water productivity. The study was among two treatments with three replicated plots at each of the study areas and each plot size prepared was 10 m X 10 m. Data collected during the study were: plant height, soil moisture content of the soil, irrigation depth and biomass yield. To determine the ETc of the fodder crops, water balance method was used. Kc of desho grass and oats & vetch fodder crops were computed from measured ETc and ETo which was calculated from weather data. Seasonal ETc of desho grass and oats and vetch was 206 and 186 mm respectively. Kc values of desho grass at early, vegetative, mid and late stages were 0.4, 0.71, 0.89, and 0.72 respectively whereas for oats & vetch was 0.29, 0.89, 1.01, and 0.71 respectively. Plant height at the mid and late stage for both fodder crops; biomass yield and irrigation water productivity were significantly different at a significant level of (p<=0.05) among treatment plots for both crops. At the mid and late stages of Desho grass, the plant height under WFD treatment was higher than the control treatment by 28% and 23% respectively whereas the plant height of oats and vetch under WFD treatment was higher than the control treatments at the mid and late season by 23% and 9% respectively.

description: Gauge fields coupled to dynamical matter are ubiquitous in many disciplines of physics, ranging from particle to condensed matter physics, but their implementation in large-scale quantum simulators remains challenging. Here we propose a realistic scheme for Rydberg atom array experiments in which a $\mathbb{Z}_2$ gauge structure with dynamical charges emerges on experimentally relevant timescales from only local two-body interactions and one-body terms in two spatial dimensions. The scheme enables the experimental study of a variety of models, including $(2+1)$D $\mathbb{Z}_2$ lattice gauge theories coupled to different types of dynamical matter and quantum dimer models on the honeycomb lattice, for which we derive effective Hamiltonians. We discuss ground-state phase diagrams of the experimentally most relevant effective $\mathbb{Z}_2$ lattice gauge theories with dynamical matter featuring various confined and deconfined, quantum spin liquid phases. Further, we present selected probes with immediate experimental relevance, including signatures of disorder-free localization and a thermal deconfinement transition of two charges.

description: Galactic winds are a common phenomenon in starburst galaxies in the local universe as well as at higher redshifts. Their sources are superbubbles driven by sequential supernova explosions in star forming regions, which carve out large holes in the interstellar medium and eject hot, metal enriched gas into the halo and to the galactic neighborhood. We investigate the evolution of superbubbles in exponentially stratified disks. We present advanced analytical models for the expansion of such bubbles and calculate their evolution in space and time. With these models one can derive the energy input that is needed for blow-out of superbubbles into the halo and derive the break-up of the shell, since Rayleigh-Taylor instabilities develop soon after a bubble starts to accelerate into the halo. The approximation of Kompaneets is modified in order to calculate velocity and acceleration of a bubble analytically. Our new model differs from earlier ones, because it presents for the first time an analytical calculation for the expansion of superbubbles in an exponential density distribution driven by a time-dependent energy input rate. The time-sequence of supernova explosions of OB-stars is modeled using their main sequence lifetime and an initial mass function. We calculate the morphology and kinematics of superbubbles powered by three different kinds of energy input and we derive the energy input required for blow-out as a function of the density and the scale height of the ambient interstellar medium. The Rayleigh-Taylor instability timescale in the shell is calculated in order to estimate when the shell starts to fragment and finally breaks up. Analytical models are a very efficient tool for comparison to observations, like e.g. the Local Bubble and the W4 bubble discussed in this paper, and also give insight into the dynamics of superbubble evolution.

description: Die Omnipräsenz Gottes ist, ausgehend von einigen biblischen Belegstellen, in der mittelalterlichen Scholastik als eine seiner charakteristischen Eigenschaften herausgearbeitet worden. Im Symbol des „Auges Gottes“ ist diese Zuschreibung sinnfällig dargestellt. Die durch digitale Kommunikationstechnologien bewirkte Telepräsenz hat, informatisch betrachtet, damit nichts zu tun. Dennoch konnten Assoziationen zwischen den beiden Themenkreisen nicht ausbleiben. Analogien zwischen der göttlichen und der kybernetischen Allgegenwart drängten sich auf. Die Überwachung im Netz der Informationsgesellschaft erinnert unweigerlich an die uneingeschränkte Sichtbarkeit des Menschenlebens unter dem Blick des Schöpfers. Um diese eigenartige Koinzidenz aufzuklären, werden die separaten Entwicklungen der beiden Motive nachgezeichnet und anschließend aufeinander bezogen. Es zeigt sich, dass ihre Zusammenstellung die Phantasie beflügelt, aber keiner ernsthaften Belastungsprobe standhält.
description: The omnipresence of God was formulated as one of His defining characteristics by scholastics in the Middle Ages based on several references in the Bible. The symbol of the “Eye of God” illustratively encapsulates this attribute. The telepresence afforded by digital communication technologies appears unrelated, from an informatics point of view. Yet, association between the two concepts and spheres did inevitably emerge. Overlapping analogies of divine and cybernetic ubiquity seem inescapable. Online surveillance in the era of information society lends itself to comparison with the all-seeing eye of God looking down on humanity. In order to investigate this mysterious coincidence, both concepts will be traced back to their origin and analysed in relation to each another. The similarities may offer a source of creative inspiration but ultimately do not withstand thorough examination.

description: The study of nuclear generalized parton distributions (GPDs) could be a crucial achievement of hadronic physics since they open new ways to obtain new information on the structure of bound nucleons, in particular, to access the neutron GPDs. Here, the results of calculations of 3He GPDs in Impulse Approximation are presented. The calculation of the sum of GPDs H + E, and "tilde H", with the correct limits, will be shown. These quantities, at low momentum transfer, are largely dominated by the neutron contribution so that 3He is an ideal target for these kind of studies. Nevertheless the extraction of neutron information from future 3He data could be non trivial. A procedure, which takes into account nuclear effects encoded in IA, is presented. The calculation of H,E and "tilde H" allows also to evaluate the cross section asymmetries for deeply virtual compton scattering at Jefferson Lab kinematics. Thanks to these observations, DVCS off 3He could be an ideal process to access the neutron information in the next future.

description: We apply measures of complexity, emergence and self-organization to an abstract city traffic model for comparing a traditional traffic coordination method with a self-organizing method in two scenarios: cyclic boundaries and non-orientable boundaries. We show that the measures are useful to identify and characterize different dynamical phases. It becomes clear that different operation regimes are required for different traffic demands. Thus, not only traffic is a non-stationary problem, which requires controllers to adapt constantly. Controllers must also change drastically the complexity of their behavior depending on the demand. Based on our measures, we can say that the self-organizing method achieves an adaptability level comparable to a living system.

title: Belief networks as complex systems

description: There has been extensive work on understanding belief, from a psychological, philosophical and neurobiological perspective. Meanwhile, artificial intelligence has produced compelling developments that can enrich and update the brain-as-a-computer metaphor and has tried to better
represent beliefs as cognitive probabilistic processes. In parallel, there has been a surge of research in Complexity Sciences, with applications ranging from Medicine to Finance. Some authors have already linked the connected nature of belief to the behaviour of complex networks. We would like to expand this approach to understand belief as a complex system with the main functions of providing a model of the world – including the individual and her surroundings – and producing guidelines for action. The complexsystem perspective allows us to understand some of the properties of belief systems in a comprehensive manner, which many authors have begun to study in isolation. Notably, this provides a framework to study the important phenomena of belief formation and change as processes of emergence and adaptation. In this exploratory paper, we propose an outline for this framework for this study.
description: Glaube wurde bereits vielfach aus psychologischer, philosophischer und neurobiologischer Perspektive untersucht. Inzwischen gab es im Bereich der künstlichen Intelligenz beeindruckende Fortschritte, die die metaphorische Bezeichnung des Gehirns als Computer aktuell und relevant erscheinen lassen und Versuche nahelegen, Glaube als kognitiven probabilistischen Prozess darzustellen. Gleichzeitig wurde die Komplexitätsforschung intensiviert, deren Anwendungen von der Medizin bis zum Finanzbereich reichen. Einige AutorInnen stellten bereits Zusammenhänge zwischen der Natur des Glaubens und dem Verhalten komplexer Netzwerke her. Der Ansatz, Glaube als ein komplexes System zu verstehen, dessen wichtigste Funktionen die Bereitstellung eines Weltmodells – einschließlich des Individuums und seiner Umwelt – und die Erstellung von Handlungsrichtlinien darstellen, soll hier weitergeführt werden. Ein solcher systemtheoretischer Zugang ermöglicht es, einige in der Forschung bislang zumeist isoliert betrachtete Eigenschaften von Glaubenssystemen ganzheitlicher zu verstehen. Insbesondere entwirft dieser Zugang einen Rahmen für die Untersuchung so wichtiger Phänomene wie der Glaubensbildung und der Glaubensänderung als emergente und adaptive Prozesse. Der vorliegende Artikel skizziert den Entwurf eines solchen Rahmens.

description: Very recently, it was pointed out that when basic ideas of the Swampland program are combined with the cosmological hierarchy problem (i.e. the smallness of the dark energy in Planck units) and together are confronted to experiment lead to the prediction of the existence of a single extra-dimension (dubbed the dark dimension) with characteristic length-scale in the micron range. We propose a feasible test procedure to probe the dark dimension using the highest energy cosmic rays.

description: The photoelectrodissolution of n-type silicon constitutes a convenient model system to study the nonlinear dynamics of oscillatory media. On the silicon surface, a silicon oxide layer forms. In the lateral direction, the thickness of this layer is not uniform. Rather, several spatio-temporal patterns in the oxide layer emerge spontaneously, ranging from cluster patterns and turbulence to quite peculiar dynamics like chimera states. Introducing a nonlinear global coupling in the complex Ginzburg-Landau equation allows us to identify this nonlinear coupling as the essential ingredient to describe the patterns found in the experiments. The nonlinear global coupling is designed in such a way, as to capture an important, experimentally observed feature: the spatially averaged oxide-layer thickness shows nearly harmonic oscillations. Simulations of the modified complex Ginzburg-Landau equation capture the experimental dynamics very well.

Status in U.K. – non-native.
The filamentous red alga Dasysiphonia japonica (“siphoned Japan weed”) has been recorded at several sites within Scapa Flow and four locations in the Northern Isles. It was first recorded in 2015 and was common in 2016, mainly in scrape samples. It is considered a fairly new introduction to Orkney; it was first recorded by W. G. Sanderson in 2011, during a survey dive at Gutter Sound, Scapa Flow (specimens identified by C. Moore).
The vector for the introduction to Europe from Japan is considered to be with Pacific oyster, Magallana gigas (Thunberg, 1793), importations (SjØtun et al. 2008) but, within Europe, dispersal has probably been partly through shipping movement (SjØtun et al. 2008). It was first recorded in the U.K. in 1999 at Milford Haven in Wales and in Scotland in 2004 at Alturlie Point, Moray Firth (SjØtun et al. 2008). Since then, it has been recorded in Loch Laxford, Sutherland in 2009 (Moore et al. 2010), Ullapool, Wester Ross in 2010 (Moore et al. 2011) and Shetland (Collin et al. 2015). Want et al. (2017) recorded it growing on renewable energy structures in Orkney.

description: Since 2014, the Fédération Internationale de l'Automobile has prescribed a parallel hybrid powertrain for the Formula 1 race cars. The complex low-level interactions between the thermal and the electrical part represent a non-trivial and challenging system to be controlled online. We present a novel controller architecture composed of a supervisory controller for the energy management, a feedforward cylinder deactivation controller, and a track region-dependent low-level nonlinear model predictive controller to optimize the engine actuators. Except for the nonlinear model predictive controller, the proposed controller subsystems are computationally inexpensive and are real time capable. The framework is tested and validated in a simulation environment for several realistic scenarios disturbed by driver actions or grip conditions on the track. In particular, we analyze how the control architecture deals with an unexpected gearshift trajectory during an acceleration phase. Further, we demonstrate how an increased maximum velocity trajectory impacts the online low-level controller. Our results show a suboptimality over an entire lap with respect to the benchmark solution of 49 ms and 64 ms, respectively, which we deem acceptable. Compared to the same control architecture with full knowledge of the disturbances, the suboptimality amounted to only 2 ms and 17 ms. For all case studies we show that the cylinder deactivation capability decreases the suboptimality by 7 to 8 ms.

description: Fix positive integers $p$ and $q$ with $2 \leq q \leq {p \choose 2}$. An edge-coloring of the complete graph $K_n$ is said to be a $(p, q)$-coloring if every $K_p$ receives at least $q$ different colors. The function $f(n, p, q)$ is the minimum number of colors that are needed for $K_n$ to have a $(p,q)$-coloring. This function was introduced by Erdős and Shelah about 40 years ago, but Erdős and Gyárfás were the first to study the function in a systematic way. They proved that $f(n, p, p)$ is polynomial in $n$ and asked to determine the maximum $q$, depending on $p$, for which $f(n,p,q)$ is subpolynomial in $n$. We prove that the answer is $p-1$.

description: With the resonant magnetic perturbations (RMPs) consolidating as an important tool to control the transport barrier relaxation, the mechanism on how they work is still a subject to be clearly understood. In this work we investigate the equilibrium states in the presence of RMPs for a reduced MHD model using 3D electromagnetic fluid numerical code (EMEDGE3D) with a single harmonic RMP (single magnetic island chain) and multiple harmonics RMPs in cylindrical and toroidal geometry. Two different equilibrium states were found in the presence of the RMPs with different characteristics for each of the geometries used. For the cylindrical geometry in the presence of a single RMP, the equilibrium state is characterized by a strong convective radial thermal flux and the generation of a mean poloidal velocity shear. In contrast, for toroidal geometry the thermal flux is dominated by the magnetic flutter. For multiple RMPs, the high amplitude of the convective flux and poloidal rotation are basically the same in cylindrical geometry, but in toroidal geometry the convective thermal flux and the poloidal rotation appear only with the islands overlapping of the linear coupling between neighbouring poloidal wavenumbers $m$, $m-1$, $m+1$.

description: In competitive sport environments, coaches and sport psychology practitioners work to optimize individual and team performance. One strategy identified as a key to optimal sport performance is athlete self-awareness. This study evaluated the efficacy of a novel, online post-event reflection (PER) tool. Using a mixed methods design, 22 members of a competitive women’s ice hockey team completed the PER across one season. The PER demonstrated efficacy through tailored insight used as a basis for athlete discussions, complementing other performance-related feedback. Follow-up interviews with three team members and the head coach provided additional support for the efficacy of the PER. Lay summary: In competitive sport environments, coaches and sport psychology practitioners work to optimize individual and team performance. This study provides evidence to support the use a novel, online post-event reflection tool by athletes, coaches, and sport psychology practitioners to enhance athlete self-awareness of mental skills and performance. When striving to optimize performance, coaches and sport psychology practitioners should consider strategies to enhance athlete self-awareness The post event reflection (PER) tool is an effective online tool for athletes, coaches, and sport psychology practitioners to enhance athlete self-awareness of mental skills and performance The PER is also a valuable diagnostic tool for coaches and sport psychology practitioners to identify individual athlete and team patterns in mental skills and performance

description: We report the evolution of the electronic structure at the surface of the layered perovskite Sr$_2$RuO$_4$ under large in-plane uniaxial compression, leading to anisotropic $B_{1g}$ strains of ${\varepsilon_{xx}-\varepsilon_{yy}=-0.9\pm0.1\%}$. From angle-resolved photoemission, we show how this drives a sequence of Lifshitz transitions, reshaping the low-energy electronic structure and the rich spectrum of van Hove singularities that the surface layer of Sr$_2$RuO$_4$ hosts. From comparison to tight-binding modelling, we find that the strain is accommodated predominantly by bond-length changes rather than modifications of octahedral tilt and rotation angles. Our study sheds new light on the nature of structural distortions at oxide surfaces, and how targeted control of these can be used to tune density of states singularities to the Fermi level, in turn paving the way to the possible realisation of rich collective states at the Sr$_2$RuO$_4$ surface.
Stochastic Zeroth Order Gradient and Hessian Estimators: Variance Reduction and Refined Bias Bounds

description: We study stochastic zeroth order gradient and Hessian estimators for real-valued functions in $\mathbb{R}^n$. We show that, via taking finite difference along random orthogonal directions, the variance of the stochastic finite difference estimators can be significantly reduced. In particular, we design estimators for smooth functions such that, if one uses $ Θ\left( k \right) $ random directions sampled from the Stiefel's manifold $ \text{St} (n,k) $ and finite-difference granularity $δ$, the variance of the gradient estimator is bounded by $ \mathcal{O} \left( \left( \frac{n}{k} - 1 \right) + \left( \frac{n^2}{k} - n \right) δ^2 + \frac{ n^2 δ^4 }{ k } \right) $, and the variance of the Hessian estimator is bounded by $\mathcal{O} \left( \left( \frac{n^2}{k^2} - 1 \right) + \left( \frac{n^4}{k^2} - n^2 \right) δ^2 + \frac{n^4 δ^4 }{k^2} \right) $. When $k = n$, the variances become negligibly small. In addition, we provide improved bias bounds for the estimators. The bias of both gradient and Hessian estimators for smooth function $f$ is of order $\mathcal{O} \left( δ^2 Γ\right)$, where $δ$ is the finite-difference granularity, and $ Γ$ depends on high order derivatives of $f$. Our results are evidenced by empirical observations.
