description: Thermoelectrics are promising by directly generating electricity from waste heat. However, (sub-)room-temperature thermoelectrics have been a long-standing challenge due to vanishing electronic entropy at low temperatures. Topological materials offer a new avenue for energy harvesting applications. Recent theories predicted that topological semimetals at the quantum limit can lead to a large, non-saturating thermopower and a quantized thermoelectric Hall conductivity approaching a universal value. Here, we experimentally demonstrate the non-saturating thermopower and quantized thermoelectric Hall effect in the topological Weyl semimetal (WSM) tantalum phosphide (TaP). An ultrahigh longitudinal thermopower Sxx= 1.1x10^3 muV/K and giant power factor ~525 muW/cm/K^2 are observed at ~40K, which is largely attributed to the quantized thermoelectric Hall effect. Our work highlights the unique quantized thermoelectric Hall effect realized in a WSM toward low-temperature energy harvesting applications.

description: We interpret the Holographic Conjecture in terms of quantum bits (qubits). N-qubit states are associated with surfaces that are punctured in N points by spin networks' edges labeled by the spin-1/2 representation of SU(2), which are in a superposed quantum state of spin "up" and spin "down". The formalism is applied in particular to de Sitter horizons, and leads to a picture of the early inflationary universe in terms of quantum computation. A discrete micro-causality emerges, where the time parameter is being defined by the discrete increase of entropy. Then, the model is analysed in the framework of the theory of presheaves (varying sets on a causal set) and we get a quantum history. A (bosonic) Fock space of the whole history is considered. The Fock space wavefunction, which resembles a Bose-Einstein condensate, undergoes decoherence at the end of inflation. This fact seems to be responsible for the rather low entropy of our universe.

description: Estimating Wasserstein distances between two high-dimensional densities suffers from the curse of dimensionality: one needs an exponential (wrt dimension) number of samples to ensure that the distance between two empirical measures is comparable to the distance between the original densities. Therefore, optimal transport (OT) can only be used in machine learning if it is substantially regularized. On the other hand, one of the greatest achievements of the OT literature in recent years lies in regularity theory: Caffarelli showed that the OT map between two well behaved measures is Lipschitz, or equivalently when considering 2-Wasserstein distances, that Brenier convex potentials (whose gradient yields an optimal map) are smooth. We propose in this work to draw inspiration from this theory and use regularity as a regularization tool. We give algorithms operating on two discrete measures that can recover nearly optimal transport maps with small distortion, or equivalently, nearly optimal Brenier potentials that are strongly convex and smooth. The problem boils down to solving alternatively a convex QCQP and a discrete OT problem, granting access to the values and gradients of the Brenier potential not only on sampled points, but also out of sample at the cost of solving a simpler QCQP for each evaluation. We propose algorithms to estimate and evaluate transport maps with desired regularity properties, benchmark their statistical performance, apply them to domain adaptation and visualize their action on a color transfer task.

Not just a recreational activity: giving artmaking the place it deserves in early childhood classrooms

description: Visual arts are languages young children use to communicate their experience and knowledge, express thoughts and feelings and interpret the world that surrounds them. As a spontaneous and uncoded language, artmaking has many advantages over verbal language. Among others, it offers vital opportunities to young learners to effectively construct meaning and concepts, appropriate new knowledge and improve their communicative and linguistic abilities. Acknowledging that visual languages feature prominently in the computer age that young learners grow up, this article considers artmaking as something more than a recreational activity and discusses how it can be used as tool for learning and teaching in early childhood. Being informed by the socio-cultural approaches, the authors analyse cases from practice and argue how it can be integrated in different areas of the curriculum, while they suggest ways to make it integral part of the classroom culture.

description: We present a comprehensive photometric and spectroscopic analysis of the short-period ($\sim$5.32 hours) and low-mass eclipsing binary TMTSJ0803 discovered by Tsinghua-Ma Huateng Telescope for Survey (TMTS). By fitting the light curves and radial velocity data with the Wilson--Devinney code, we find that the binary is composed of two late spotted active M dwarfs below the fully convective boundary. This is supported by the discovery of a significant Balmer emission lines in the LAMOST spectrum and prominent coronal X-ray emission. In comparison with the typical luminosity of rapidly rotating fully convective stars, the much brighter X-ray luminosity ($L_{X}/L_{\rm{bol}} = 0.0159 \pm 0.0059$) suggests the stellar magnetic activity of fully convective stars could be enhanced in such a close binary system. Given the metallicity of [M/H] = $-$ 0.35 dex as inferred from the LAMOST spectrum, we measure the masses and radii of both stars to be $M_{1} = 0.169 \pm 0.010~M_{\odot}$, $M_{2} = 0.162 \pm 0.016~M_{\odot}$, $R_{1} = 0.170 \pm 0.006~R_{\odot}$, and $R_{2} = 0.156 \pm 0.006~R_{\odot}$, respectively. Based on the luminosity ratio from the light curve modeling, the effective temperatures of two components are also estimated. In comparison with the stellar evolution models, the radii and effective temperatures of two components are all below the isochrones. The radius deflation might be mainly biased by a small radial velocity (RV) data or (and) a simple correction on RVs, while the discrepancy in effective temperature might be due to the enhanced magnetic activity in this binary.

description: A group of new zwitterion based ionic liquid crystals (ILCs) have been synthesized. Depending on the counter anion (mesylate or hydrogen sulfate) the phase behavior of the resulting ILCs is quite different. Mesylate based ILCs show complex phase behavior with multiple phases depending on the alkyl chain length. In contrast, hydrogen sulfate based systems always exhibit Colr phases irrespective of the alkyl chain length. The latter show much larger ILC mesophase windows and are thermally stable up to ca. 200 °C. All ILCs show reasonable ionic conductivities of up to 10-4 S cm-1 at elevated temperatures, making these ILCs candidates for intermediate temperature ionic conductors.

description: Calibration models have been developed for determination of trace elements, silver for instance, in soil using laser-induced breakdown spectroscopy (LIBS). The major concern is the matrix effect. Although it affects the accuracy of LIBS measurements in a general way, the effect appears accentuated for soil because of large variation of chemical and physical properties among different soils. The purpose is to reduce its influence in such way an accurate and soil-independent calibration model can be constructed. At the same time, the developed model should efficiently reduce experimental fluctuations affecting measurement precision. A univariate model first reveals obvious influence of matrix effect and important experimental fluctuation. A multivariate model has been then developed. A key point is the introduction of generalized spectrum where variables representing the soil type are explicitly included. Machine learning has been used to develop the model. After a necessary pretreatment where a feature selection process reduces the dimension of raw spectrum accordingly to the number of available spectra, the data have been fed in to a back-propagation neuronal networks (BPNN) to train and validate the model. The resulted soilindependent calibration model allows average relative error of calibration (REC) and average relative error of prediction (REP) within the range of 5-6%.

Perceptions held by teachers in designing and evaluating visual activities in preschool education: the assessment of “beauty” as a standard
Creators: name: DOKA, ANTIGONI
Publisher: name: Educational Journal of the University of Patras UNESCO Chair
Year: 2017
Subjects: Art education, didactics, aesthetics and education

description: Visual activities in schools and especially in preschool education are quite often designed, implemented and evaluated by definitions relating to categories of “beauty”, as these are understood in every case. Consequently, the evaluation and feedback on an act of teaching are primarily assessed on the basis of an aesthetic quality. This accordingly creates a condition that defines the method for teaching visual education, and also influences the development of specific aesthetic criteria in children through their gradual adaption to a specified standard. On the basis of this approach a formulaic perception regarding art and its teaching is to be found, whereby the work of art is defined on the basis of its form, which must comply to specific criteria with universal validity. Our aim is to investigate the aspects and the extent of this specific practice, and its impact upon the features and quality of the available activities; to determine the extent to which it is a conscious choice on the part of teachers and to what degree it is associated with the theoretical approaches of visual education. Our methodology is based upon interviews conducted with teachers that are active in the broader Patras region. These interviews were open-ended, and the interviewees were permitted to deviate by expounding their personal views and considerations.

Action Principle in Nonequilibrium Statistical Dynamics
Creators: name: Eyink, Gregory L.
Publisher: name: arXiv
Year: 1996
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: We introduce a variational method for approximating distribution functions of dynamics with a ``Liouville operator'' $\hL,$ in terms of a {\em nonequilibrium action functional} for two independent (left and right) trial states. The method is valid for deterministic or stochastic Markov dynamics, and for stationary or time-dependent distributions. A practical Rayleigh-Ritz procedure is advanced, whose inputs are finitely-parametrized ansatz for the trial states, leading to a ``parametric action'' for their evolution. The Euler-Lagrange equations of the action principle are Hamiltonian in form (generally noncanonical). This permits a simple identification of fixed points as critical points of the parametric Hamiltonian. We also establish a variational principle for low-order statistics, such as mean values and correlation functions, by means of {\em least effective action.} The latter is a functional of the given variable, which is positive and convex as a consequence of Hölder realizability inequalities. Its value measures the ``cost'' for a fluctuation from the average to occur and in a weak-noise limit it reduces to the Onsager-Machlup action. In general, the effective action is shown to arise from the nonequilibrium action functional by a constrained variation. This result provides a Rayleigh-Ritz scheme for calculating just the desired low-order statistics, with internal consistency checks less demanding than for the full distribution.

description: Klassenungleichverteilung ist eine große Herausforderung in der Klassifikation. Wenn Daten eine Klassenungleichverteilung aufweisen, erzielen einzelne Klassifikationsmodelle oft eine unzureichende Vorhersagegenauigkeit. Um dieses Problem zu lösen, können spezielle Ensemble-Methoden angewendet werden. Ein Ensemble ist eine Kombination aus mehreren einzelnen Klassifikationsmodellen. Da die Erstellung eines Ensembles jedoch komplex ist, werden häufig Automated Machine Learning (AutoML) Frameworks eingesetzt. Diese erlauben das automatisierte Erstellen eines Ensembles. Obwohl bereits einige Ensemble-Methoden zur Behandlung von Klassenungleichverteilung in der Literatur existieren, werden diese kaum im Kontext von AutoML-Frameworks betrachtet. Vor diesem Hintergrund wird in dieser Arbeit ein Ansatz zur Erweiterung eines bestehenden AutoML-Frameworks vorgestellt, um das Problem der Klassenungleichverteilung zu behandeln. Dafür umfasst der Beitrag dieser Arbeit Folgendes: Analyse und Identifizierung von Ensemble-Methoden zur Behandlung von Klassenungleichverteilung, die für die Integration in das AutoML-Framework geeignet sind. Erstellung eines Konzepts zur Integration der identifizierten Methoden in das AutoML-Framework. Evaluation des Konzepts anhand acht Echtweltdatensätzen, die eine Klassenungleichverteilung aufweisen. Die Ergebnisse der Evaluation zeigen hierbei eine Verbesserung der Vorhersagegenauigkeit auf ungleich verteilten Daten sowie eine erhöhte Diversität der erstellten Ensembles.

description: The questions asked by the teacher in class are varied. Some questions require a simple recall of information, others stimulate reasoning. The various reasons for questioning and the combination of activities in the class can guide the discussion and help teachers to develop explanatory approaches which are appropriate in various situations in the classroom, in the laboratory or on the terrain. We examine, here, the teacher’s questions in a geological practical session at the ST4 level (master level in Earth Sciences). The analytical grid for these questions was pre-established. Reasons behind the questioning may be conceptual, empirical, pedagogic or value- or transfer-orientated. Does the interaction between these questions lead to scientific problems?

description: Total Quality Management (TQM) has been subjected to definitional ambiguities among scholars and practitioners in the sense that there is a lack of consensus as to the exact meaning of the term. While some authors contend that TQM is a set of management values, others conceptualise it as a strategy and philosophy. Notwithstanding the foregoing, TQM is acknowledged as a critical, comprehensive and complex management topic which based on a large number of principles embraces all aspects of the organisation as well as its customers and suppliers. Despite a plethora of TQM research studies; there is an evident scarcity in scholarly literature about the hierarchical nature of TQM drivers and enablers. The paucity of research on how TQM drivers and enablers influence each other, and how they, individually or collectively, influence organisational outcomes is surprising in light of the widespread adoption of TQM. In the Australian context, TQM is deployed widely through compliance with: (1) the international management standard ISO 9001, or (2) through an elemental approach as promoted by many of the TQM practitioners, consultants and professed experts in the field, or (3) by alignment with the prize-criteria Australian Business Excellence Framework (ABEF), or more often, some combination of all three approaches. In view of the above, this research study reports on a critical investigation of the hierarchical nature of TQM drivers and enablers. A review of the literature identified 16 drivers and enablers group elements (attributes), which positively influence organisational outcomes. The study adopted Interpretive Structural Modelling (ISM) to help structure the collective knowledge of a group of TQM experts (via a pilot study) in order to construct a hierarchical network representation of the complex pattern of the contextual relationship among all pairs of identified drivers and enablers. Eleven experts from differing organisations in industry, academia and the government participated in this pilot study. The collective views and responses were developed into an online Research Questionnaire, which 159 respondents from differing Australian organisations completed.

description: Single bubble sonoluminescence is understood in terms of a shock focusing towards the bubble center. We present a mechanism for significantly enhancing the effect of shock focusing, arising from the storage of energy in the acoustic modes of the gas. The modes with strongest coupling are not spherically symmetric. The storage of acoustic energy gives a framework for understanding how light intensities depend so strongly on ambient gases and liquids and suggests that the light intensities of successive flashes are highly correlated.

description: Unternehmen der industriellen Produktion befinden sich in einem turbulenten Umfeld, in dem interne und externe Wandlungstreiber eine ständige Adaption fordern. Neue Technologien wie die additive Fertigung liefern wichtige Impulse für ein Unternehmen und bedingen gleichzeitig große Hürden bei der Integration in bestehende Fertigungsstrukturen. Trotz intensiver Forschungsbemühungen liegen additive Technologien mit metallischen Werkstoffen hinter ihren Erwartungen an Qualität und Reproduzierbarkeit zurück. Die grundsätzlich abweichenden peripheren Prozesse und die kurze Dauer der Existenz stellen zusätzliche Herausforderungen an die weitere Entwicklung. Vor diesem Hintergrund liegt die Zielsetzung dieser Arbeit in der Entwicklung eines rekursiven Modells zur Bestimmung der Prozess- und Wirkzusammenhänge in der additiven Fertigung mit metallischen Werkstoffen. Durch die Anpassung an das laser- und pulverbettbasierte selektive Schmelzen wird die Tiefe des Prozessverständnisses erweitert. Die systematische Vorgehensweise sieht eine Modularisierung entlang der Prozessketten vor, ausgehend vom Produktlebenszyklus bis zum Prozessursprung, um eine Untersuchung der Einflussfaktoren auf vielen Ebenen zu ermöglichen. Abschließend werden die gewonnenen Erkenntnisse entlang der Prozessketten zurück projiziert, um sicherzustellen, dass die Auswirkungen der neuen Erkenntnisse nachvollzogen werden können. Zur Validierung wurde die Modularisierung für das selektive Schmelzen bis zum Prozessursprung durchgeführt, Untersuchungen mittels molekulardynamischer Simulation ausgeführt und die Ergebnisse rekursiv auf übergeordnete Prozessebenen übertragen.

description: Cancer is a group of complex diseases characterized by the uncontrolled growth and division of abnormal cells that can affect virtually any tissue or organ in the body. Together, these diseases continue to challenge medical science and impact millions of lives worldwide. Despite substantial progress in cancer treatments, the quest for better therapies, and ultimately for a cure for all forms of cancer remains elusive. As cancer drug discovery enters an era of precision medicine, cyanobacteria offer a promising source of new drugs. Their biodiversity provides a vast reservoir of pharmacologically active metabolites, whilst their ability to thrive in diverse ecological niches suggests untapped natural resources. The present study attempted to improve the knowledge of anti-proliferative potential, cytotoxicity, relative safety and anticancer properties of relatively poorly studied cyanobacteria species and to verify their suitability for chemotherapeutic treatments of treat some cancers.

description: Environment perception is the task for intelligent vehicles on which all subsequent steps rely. A key part of perception is to safely detect other road users such as vehicles, pedestrians, and cyclists. With modern deep learning techniques huge progress was made over the last years in this field. However such deep learning based object detection models cannot predict how certain they are in their predictions, potentially hampering the performance of later steps such as tracking or sensor fusion. We present a viable approaches to estimate uncertainty in an one-stage object detector, while improving the detection performance of the baseline approach. The proposed model is evaluated on a large scale automotive pedestrian dataset. Experimental results show that the uncertainty outputted by our system is coupled with detection accuracy and the occlusion level of pedestrians.

description: Recent advances in pressure coring techniques, such as the HYACINTH and IODP PCS pressure cores deployed during Expedition 1 of the India National Gas Hydrate Program using the JOIDES Resolution have enabled the recovery of fine grained sediments with intact gas hydrates contained within the sediments. This has provided the opportunity to study the morphology of gas hydrates within fine grained sediments which until now has been hindered due to the long transit times during core recovery leading to the dissociation of the gas hydrates. Once recovered from the seafloor, rapid depressurization and subsequent freezing of the cores in liquid nitrogen has enabled the near complete fine fracture filling nature of the gas hydrates to be largely preserved. High resolution X-ray CT (computer tomography), which has a pixel resolution of approx. 0.07mm, has been used to provide detailed images showing the 3-dimensional distribution of hydrates within the recovered fine grained sediments. Results have shown that in fine grained sediments gas hydrates grow along fine fracture faults within the sediment. Although the fractures were predominantly sub-vertical and continuous through the cores, stranded fractures were also observed suggesting that hydrate formation is episodic. However, within the cores open voids were observed which were not evident in low resolution CT images taken before the depressurization step suggesting that during depressurization either finely disseminated gas hydrate was dissociated or that gas exsolving from solution created these voids in the sample prior to freezing in liquid nitrogen. These detailed observations of gas hydrate in fine grained sediments will help us understand the differing morphology of gas hydrates in sediments. They also show that sample disturbance is still a major concern and further techniques are required to restrict these effects so that meaningful laboratory tests can be undertaken on recovered samples.
Tailoring ink-substrate interactions via thin polymeric layers for high-resolution printing

description: The surface properties of a substrate are among the most important parameters in the printing technology of functional materials, determining not only the printing resolution but also the stability of the printed features. This paper addresses the wetting difficulties encountered during inkjet printing on homogeneous substrates as a result of improper surface properties. We show that the wetting of a substrate and, consequently, the quality of the printed pattern, can be mediated through the deposition of polymeric layers that are a few nanometers thick. The chemical nature of the polymers determines the surface energy and polarity of the thin layer. Some applications, however, require a rigorous adjustment of the surface properties. We propose a simple and precise method of surface-energy tailoring based on the thermal decomposition of poly(methyl methacrylate) (PMMA) layers. A smooth transition in the wetting occurs when the thickness of the PMMA layer approaches zero, probably due to percolating the underlying surface of the substrate, which enables the inkjet printing of complex structures with a high resolution. In particular, the wetting of three substrate-ink systems was successfully adjusted using the thin polymeric layer: (i) a tantalum-oxide-based ink on indium-tin-oxide-coated glass, (ii) a ferroelectric lead zirconate titanate ink on a platinized silicon substrate, and (iii) a silver nanoparticle ink on an alumina substrate.
Incorporating elements of heuristic research in teaching Anthropology

Subjects: Anthropology, teaching, heuristic research

description: An examination is presently attempted of whether anthropological teaching may to some extent blend well with elements of heuristic research. Since heuristic research gives emphasis to personal involvement and focuses on queries pertinent to the individual, it could possibly enhance the usefulness of any anthropological knowledge a student receives. Such an approach would perhaps be more fitting for teaching at a university level, providing an interesting add-on to anthropology courses that are not addressed to would-be anthropologists.

description: In this chapter we consider different approximations for the one-dimensional one-phase Stefan problem corresponding to the fusion process of a semi-infinite material with a temperature boundary condition at the fixed face and non-linear temperature-dependent thermal conductivity. The knowledge of the exact solution of this problem, allows to compare it directly with the approximate solutions obtained by applying the heat balance integral method, an alternative form to it and the refined balance integral method, assuming a quadratic temperature profile in space. In all cases, the analysis is carried out in a dimensionless way by the Stefan number (Ste) parameter.

description: Random networks with complex topology are common in Nature, describing systems as diverse as the world wide web or social and business networks. Recently, it has been demonstrated that most large networks for which topological information is available display scale-free features. Here we study the scaling properties of the recently introduced scale-free model, that can account for the observed power-law distribution of the connectivities. We develop a mean-field method to predict the growth dynamics of the individual vertices, and use this to calculate analytically the connectivity distribution and the scaling exponents. The mean-field method can be used to address the properties of two variants of the scale-free model, that do not display power-law scaling.

description: We define Hochschild and cyclic homologies for bornological coarse spaces: for a fixed field $k$ and group $G$, these are lax symmetric monoidal functors $\mathcal{X}HH_{k}^G$ and $\mathcal{X}HC_{k}^G$ from the category of equivariant bornological coarse spaces $G\mathbf{BornCoarse}$ to the cocomplete stable $\infty$-category of chain complexes $\mathbf{Ch}_\infty$. We relate these equivariant coarse homology theories to coarse algebraic $K$-theory $\mathcal{X} K^G_{k}$ and to coarse ordinary homology $\mathcal{X} H^G$ by constructing a trace-like natural transformation $\mathcal{X} K_{k}^G\to \mathcal{X} H^G$ that factors through coarse Hochschild (or cyclic) homology. We further compare the forget-control map for coarse Hochschild homology with the associated generalized assembly map.

Petri Nets Based on Lawvere Theories

description: We give a definition of $\mathsf{Q}$-net, a generalization of Petri nets based on a Lawvere theory $\mathsf{Q}$, for which many existing variants of Petri nets are a special case. This definition is functorial with respect to change in Lawvere theory, and we exploit this to explore the relationships between different kinds of $\mathsf{Q}$-nets. To justify our definition of $\mathsf{Q}$-net, we construct a family of adjunctions for each Lawvere theory explicating the way in which $\mathsf{Q}$-nets present free models of $\mathsf{Q}$ in $\mathsf{Cat}$. This gives a functorial description of the operational semantics for an arbitrary category of $\mathsf{Q}$-nets. We show how this can be used to construct the semantics for Petri nets, pre-nets, integer nets, and elementary net systems.

METHANE BUDGET OF A LARGE GAS HYDRATE PROVINCE OFFSHORE GEORGIA, BLACK SEA

description: The Batumi Seep Area, offshore Georgia, Black Sea, has been intensively cored (gravity cores and TV-guided multi-cores) to investigate the methane turnover in the surface sediments. The seep area is characterized by vigorous methane gas bubble emanations. Geochemical analyses show a microbial origin of the methane and a shallow fluid source. Anaerobic methane oxidation rapidly consumes the SO4 2- within the top 5-20 cm, but significant upward fluid advection is not indicated by the porewater profiles. Hence, the Batumi Seep Area must be dominated by methane gas seepage in order to explain the required CH4 flux from below. 1-D transport-reaction modelling constrains the methane flux needed to support the observed SO4 2- flux as well as the rate of near-surface hydrate formation. The model results correlate well with the hydro-acoustic backscatter intensities recorded and mapped bubble release sites using the sonar of a ROV.
