description: Thermoelectrics are promising to address energy issues but their exploitation is still hampered by low efficiencies. So far, much improvement has been achieved by reducing the thermal conductivity but less by maximizing the power factor. The latter imposes apparently conflicting requirements on the band structure: a narrow energy distribution and a low effective mass. Quantum confinement in nanostructures or the introduction of resonant states were suggested as possible solutions to this paradox but with limited success. Here, we propose an original approach to fulfill both requirements in bulk semiconductors. It exploits the highly-directional character of some orbitals to engineer the band-structure and produce a type of low-dimensional transport similar to that targeted in nanostructures, while retaining isotropic properties. Using first-principles calculations, the theoretical concept is demonstrated in Fe$_2$YZ Heusler compounds, yielding power factors 4-5 times larger than in classical thermoelectrics at room temperature. Our findings are totally generic and rationalize the search of alternative compounds with a similar behavior. Beyond thermoelectricity, these might be relevant also in the context of electronic, superconducting or photovoltaic applications.

description: Using a Tecan robotic sample processor and IBM compatible PCs we have developed a flexible, partially automated radioligand binding assay system. It handles pipetting parameters of up to 16 saturation or competition experiments at a time with up to 24 radioligand- or competitor-concentrations in a range over 4 orders of magnitude per experiment. The system provides enough flexibility so that all pipetting parameters including different tube-, rack-sizes, sample volumina and pipetting sequences may be easily adapted to the large variety of experimental requirements in binding assays. It rationalizes and increases assay throughput (up to 70% spare of working time), improves reliance and reproducibility of results. Radioactive exposure is minimized to the time preparing the radioligand working solution and transferring the sample tubes to and from the sample processor. The system has proven effective in various investigations on binding interactions, as well as in clinical studies on receptor expression under physiologic, pathological and therapeutic conditions.

description: Excerpts from the report Introduction: A study team was convened by the USDA Director of Economics, Policy Analysis, and Budget to examine options for improving the flow of U.S. food and agricultural technical assistance resources to developing countries. The team undertook a search of available literature on the subject and interviewed numerous experts to obtain their views. A draft report was circulated widely within USDA for comments, which were considered by the study team in finalizing the report. This paper reviews technical assistance activities of the U.S. Government, discusses the present and future supply/demand scenario for U.S. technical assistance resources, identifies constraints and formulates options for improving the transfer of food and agriculture technology to the developing countries.
description: Little research has been published on the amount or effectiveness of technical assistance programs. Because of its recent work in studying AID-related activities. Development Alternatives, Inc. (DAI) was retained to provide a brief assessment of technical assistance efforts. The DAI report constitutes Appendix 2 of this paper. While the study team does not necessarily endorse all DAI conclusions, they do serve as an additional basis for the assessment contained in this paper.
On-surface radiation condition for multiple scattering of waves

description: The formulation of the on-surface radiation condition (OSRC) is extended to handle wave scattering problems in the presence of multiple obstacles. The new multiple-OSRC simultaneously accounts for the outgoing behavior of the wave fields, as well as, the multiple wave reflections between the obstacles. Like boundary integral equations (BIE), this method leads to a reduction in dimensionality (from volume to surface) of the discretization region. However, as opposed to BIE, the proposed technique leads to boundary integral equations with smooth kernels. Hence, these Fredholm integral equations can be handled accurately and robustly with standard numerical approaches without the need to remove singularities. Moreover, under weak scattering conditions, this approach renders a convergent iterative method which bypasses the need to solve single scattering problems at each iteration. Inherited from the original OSRC, the proposed multiple-OSRC is generally a crude approximate method. If accuracy is not satisfactory, this approach may serve as a good initial guess or as an inexpensive pre-conditioner for Krylov iterative solutions of BIE.

Analysing and Reducing Costs of Deep Learning Compiler Auto-tuning
Creators: name: Borowiec, Damian
Publisher: name: Lancaster University

description: Deep Learning (DL) is significantly impacting many industries, including automotive, retail and medicine, enabling autonomous driving, recommender systems and genomics modelling, amongst other applications. At the same time, demand for complex and fast DL models is continually growing. The most capable models tend to exhibit highest operational costs, primarily due to their large computational resource footprint and inefficient utilisation of computational resources employed by DL systems. In an attempt to tackle these problems, DL compilers and auto-tuners emerged, automating the traditionally manual task of DL model performance optimisation. While auto-tuning improves model inference speed, it is a costly process, which limits its wider adoption within DL deployment pipelines. The high operational costs associated with DL auto-tuning have multiple causes. During operation, DL auto-tuners explore large search spaces consisting of billions of tensor programs, to propose potential candidates that improve DL model inference latency. Subsequently, DL auto-tuners measure candidate performance in isolation on the target-device, which constitutes the majority of auto-tuning compute-time. Suboptimal candidate proposals, combined with their serial measurement in an isolated target-device lead to prolonged optimisation time and reduced resource availability, ultimately reducing cost-efficiency of the process. In this thesis, we investigate the reasons behind prolonged DL auto-tuning and quantify their impact on the optimisation costs, revealing directions for improved DL auto-tuner design. Based on these insights, we propose two complementary systems: Trimmer and DOPpler. Trimmer improves tensor program search efficacy by filtering out poorly performing candidates, and controls end-to-end auto-tuning using cost objectives, monitoring optimisation cost. Simultaneously, DOPpler breaks long-held assumptions about the serial candidate measurements by successfully parallelising them intra-device, with minimal penalty to optimisation quality. Through extensive experimental evaluation of both systems, we demonstrate that they significantly improve cost-efficiency of autotuning (up to 50.5%) across a plethora of tensor operators, DL models, auto-tuners and target-devices.

Wilson loop OPE, analytic continuation and multi-Regge limit
Creators: name: Hatsuda, Yasuyuki
Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We explore a direct connection between the collinear limit and the multi-Regge limit for scattering amplitudes in the N=4 super Yang-Mills theory. Starting with the collinear expansion for the six-gluon amplitude in the Euclidean kinematic region, we perform an analytic continuation term by term to the so-called Mandelstam region. We find that the result coincides with the collinear expansion of the analytically continued amplitude. We then take the multi-Regge limit, and conjecture that the final result precisely reproduces the one from the BFKL approach. Combining this procedure with the OPE for null polygonal Wilson loops, we explicitly compute the leading contribution in the "collinear-Regge" limit up to five loops. Our results agree with all the known results up to four loops. At five-loop, our results up to the next-to-next-to-leading logarithmic approximation (NNLLA) also reproduce the known results, and for the N^3LLA and the N^4LLA give non-trivial predictions. We further present an all-loop prediction for the imaginary part of the next-to-double-leading logarithmic approximation. Our procedure has a possibility of an interpolation from weak to strong coupling in the multi-Regge limit with the help of the OPE.

description: Background/context. Coaching is an effective way to unlock one’s potential to maximise performance. Adoption of coaching in education has grown over the past decade, with positive impact on learners and stakeholders (van Nieuwerburgh & Barr, 2016). Coaching helps improve students’ sense of control over their studies, have better focus and work balance, increase confidence, and develop a wider perspective on issues (Lancer & Eatough, 2018). Integrating coaching into higher education can transform universities by making faculty more learner-centric, thereby raising students’ performance and wellbeing. To achieve this, coach training for faculty is needed. Equipped with a coaching mindset and coaching competencies, faculty can engage in coaching conversations with students. The initiative/practice. For faculty, we have a practice-focused workshop contextualised to educational settings. Participants learn about coaching mindset, coachable moments, and coaching competencies, with practice sessions using coaching scenarios and role plays customised to academic contexts. A quiz is administered to test coaching knowledge. Participants demonstrate their coaching skills with standardised student-actors, with observers present to assess and share individualised feedback. Surveys and reflection exercises are also conducted. Methods of evaluative data collection and analysis. Evaluation on the effectiveness of training programme was conducted, through surveys with 119 educators across different disciplines. Reflection surveys were analysed thematically to identify key learning takeaways. Evidence of outcomes and effectiveness. The surveys indicated significant improvement (p < .001) in coaching mindset after the training. Participants reported several key learnings from the training: coaching conversation frameworks, active listening, asking coaching questions, and solution-focus approach over root cause. Many were able to suggest possible coaching applications when working with students. Beyond coaching workshops, developing an institutional coaching culture can be enhanced through peer learning platforms, such as Coaching Community of Practice and Coaching Circles, creating a coaching knowledge repository, and promoting academic coaching research.

title: Forgotten connections : reviving the concept of upbringing in Scottish child welfare
Creators: name: Smith, Mark
Publisher: name: Strathprints - University of Strathclyde
Year: 2013

description: The concept of upbringing is a central one in social pedagogy. It is also apparent in a Scottish social welfare tradition, most evidently in the 1964 Kilbrandon Report. Kilbrandon's broad understanding of upbringing or social education was, however, subsequently subsumed beneath increasingly compartmentalised and instrumental approaches to child care and education. These fail to adequately understand and, arguably, impede and distort adult responsibility for bringing up children. This article draws on European literature, and particularly the writing of the German social pedagogue Klaus Mollenhauer, to begin to articulate the concept of upbringing, locating it as the central task of child care and education. Bringing up children is identified as, fundamentally, a moral and cultural endeavour, brought about through caring, inter-generational relationships. The article concludes by suggesting that elements within a Scottish tradition and within current policy might be drawn on to support a broad understanding of upbringing.

description: Chemistry as an unconventional computing medium presently lacks a systematic approach to gather, store, and sort data over time. To build more complicated systems in chemistries, the ability to look at data in the past would be a valuable tool to perform complex calculations. In this paper we present the first implementation of a chemical delay line providing information storage in a chemistry that can reliably capture information over an extended period of time. The delay line is capable of parallel operations in a single instruction, multiple data (SIMD) fashion. Using Michaelis-Menten kinetics, we describe the chemical delay line implementation featuring an enzyme acting as a means to reduce copy errors. We also discuss how information is randomly accessible from any element on the delay line. Our work shows how the chemical delay line retains and provides a value from a previous cycle. The system's modularity allows for integration with existing chemical systems. We exemplify the delay line capabilities by integration with a threshold asymmetric signal perceptron to demonstrate how it learns all 14 linearly separable binary functions over a size two sliding window. The delay line has applications in biomedical diagnosis and treatment, such as smart drug delivery.

description: To ascertain the efficiency of different techniques of arthroscopic therapy for gonarthritis and establish the relevance of the extent of chondromalacia, clinical and experimental studies were performed. In principle, the process of chondromalacia determines the course of the disease. Treatment of additional meniscus lesions temporarily leads to better clinical results, but after only a few months the symptoms caused by the arthritic process reappear. Compared with the temporary relief of complaints after debridement and lavage, smoothing with a xenon chloride excimer laser in grade II chondromalacia leads to statistically significantly better clinical results. Scanning electron microscopic studies confirm the extremely good smoothing. These studies permit clear statements as to the various methods of treatment and their application in the different grades of chondromalacia, thus leading to differentiated arthroscopic treatment of degenerative gonarthritis.

description: A closed 6R linkage is generically rigid. Special cases may be mobile. Many families of mobile 6R linkages have been characterised in terms of the invariant Denavit-Hartenberg parameters of the linkage. In other words, many sufficient conditions for mobility are known. In this paper we give, for the first time, equational conditions on the invariant Denavit-Hartenberg parameters that are necessary for mobility. The method is based on the theory of bonds. We illustrate the method by deriving the equational conditions for various well-known linkages (Bricard's line symmetric linkage, Hooke's linkage, Dietmaier's linkage, and recent a generalization of Bricard's orthogonal linkage), starting from their bond diagrams; and by deriving the equations for another bond diagram, thereby discovering a new mobile 6R linkage.

description: Land-use changes have greatly impacted biodiversity and led to new conservation challenges, including greater predation pressure, although this can be difficult to quantify. Here we directly monitor predator encounters in fragmented woodlands by using passive acoustic monitoring (PAM) and a semi-automated assessment protocol to detect functionally referential alarm vocalisations of the noisy miner Manorina melanocephala. We demonstrate that measuring changes in perceived predation pressure, the so-called ‘landscape of fear’, in a prey species across temporal (dawn, midday, dusk across multiple seasons) and spatial scales (small/large fragments and edge/centre locations within fragments) is achievable. Vocalisations linked with ground predator presence were rarer during midday recordings, but more commonly detected from the edge rather than centre of smaller fragments. While the probability of detecting aerial alarm calls directed at flying raptors also increased in edge habitat, aerial alarm detections declined from a dawn peak to a minimum during dusk recordings. These patterns did not simply reflect noisy miner occupancy or different sections of monitored patches, but highlighted higher perceived predation risk along edges, particularly for small patches, demonstrating the nuanced insights that PAM can offer when quantifying animal behaviour.
Universality and Borel Summability of Arbitrary Quartic Tensor Models

description: We extend the study of \emph{melonic} quartic tensor models to models with arbitrary quartic interactions. This extension requires a new version of the loop vertex expansion using several species of intermediate fields and iterated Cauchy-Schwarz inequalities. Borel summability is proven, uniformly as the tensor size $N$ becomes large. Every cumulant is written as a sum of explicitly calculated terms plus a remainder, suppressed in $1/N$. Together with the existence of the large $N$ limit of the second cumulant, this proves that the corresponding sequence of probability measures is uniformly bounded and obeys the tensorial universality theorem.

description: Cetaceans depend highly on acoustic signals, such as whistles, for social communication. Mixed-species associations (MSAs), temporary or long-term encounters between different species, may play an important role on the acoustic dynamics of the species involved. Because of whistles’ communication function, we used these sounds to investigate the acoustic relationships of Tursiops truncatus when involved in different group contexts: in MSAs with two other delphinid species and in single species group. Acoustic recordings of T. truncatus single species groups and in associations with Globicephala melas and Grampus griseus were collected in the Western South Atlantic Ocean through a towed array of hydrophones. A total of 1267 whistles were analysed and acoustical parameters were extracted. To verify the differences among whistles produced in such contexts a support vector machine and random forest analysis were implemented. Both analyses revealed a clear separation of whistles from the single species versus the MSA as well as between both MSAs. The results indicate that interspecific associations may influence the whistle structure and suggests that T. truncatus whistles can be modified during interspecific interactions. These findings are useful to elucidate the possible factors underlying behavioural plasticity and interspecific associations and to understand dolphins’ acoustic communication.

description: Clinical examination still plays an important role in diagnosing meniscal tears. The types of sensitive nerves in the knee joint are responsible for nonspecific pain, which is often correlated with too little specificity in meniscal tests. Ultrasound examination of meniscal structures of the knee joint has been debated extensively in recent years. Criticism of this noninvasive technique was due to small patient groups, improper technical and inaccurate manual standards. Since 1988 ultrasound of the tibial meniscus has become a standard technique in our Department of Orthopaedic Surgery with defined criteria of the intersecting plane and evaluation of ultrasound images. A prospective follow-up study during 6/1988 and 5/1993 including 1186 ultrasound examinations before arthroscopy, was performed. The sensitivity for ultrasound of the lateral meniscus was 58% and for the medial meniscus 83%. Specificity with 98% for the lateral and 90% for the medial meniscus was good. Sonographic detection of meniscal tears depends on the shape and location of meniscal tears. This has been shown by experimental studies in cadavers. A follow-up study including 113 knee joints was performed to prove the value of clinical and ultrasound examination in relation to arthroscopy. The sensitivity of sonography for medial meniscus was 81% and 40% for the lateral meniscus. Although the sensitivity of the clinical examination was 81% (medial) and 47% (lateral), the low specificity of 70% for meniscus tears indicated that it was because of false-positive clinical evaluation of meniscal disorders. In young patients with reflectory muscle spasm and those with acute trauma of the knee joint, clinical examination of the meniscal structures showed poor results. In these cases, too, ultrasound examination showed advantages. Ultrasound of the knee joint meniscus is noninvasive, reproducible and low cost. In cases of uncertain clinical results, ultrasound offers a good opportunity to visualize meniscal disorders.

description: In his 2011 work, Maas has shown that the law of any time-reversible continuous-time Markov chain with finite state space evolves like a gradient flow of the relative entropy with respect to its stationary distribution. In this work we show the converse to the above by showing that if the relative law of a Markov chain with finite state space evolves like a gradient flow of the relative entropy functional, it must be time-reversible. When we allow general functionals in place of the relative entropy, we show that the law of a Markov chain evolves as gradient flow if and only if the generator of the Markov chain is real diagonalisable. Finally, we discuss what aspects of the functional are uniquely determined by the Markov chain.

We also give a partial computation of the cohomology of the braid group with non-abelian coefficients coming from geometric representations. We introduce an interesting class of "sheaves over posets", which we call "weighted sheaves over posets", and use them for explicit computations.

description: In this paper we report a case of osteochondral fracture of the lateral tibial pilon. A young man fell while he was playing soccer. In the following months the ankle was swollen and painful. Later the reason for his ankle pain was clearly visible on the X-ray pictures, which revealed a severe osteochondral fracture of the lateral tibial pilon. We describe the arthroscopic and X-ray grading of osteochondral fractures of the ankle and their treatment.

Tuning antiferromagnetism of vacancies with magnetic fields in graphene nanoflakes

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: Graphene nanoflakes are interesting because electrons are naturally confined in these quasi-zero-dimensional structures, whereas confinement in bulk graphene would require a band gap. Vacancies inside the graphene lattice lead to localized states and the spins of such localized states may be used for spintronics. We perform a tight-binding description of a nanoflake with two vacancies and include a perpendicular magnetic field via a Peierls phase. The tunnel coupling strength and from it the exchange coupling between the localized states can be obtained from the energy splitting between numerically calculated bonding and antibonding energy levels. This allows us to estimate the exchange coupling J, which governs the dynamics of coupled spins. We predict the possibility of switching in situ from J>0 to J=0 by tuning the magnetic field. In the former case, the ground state will be antiferromagnetic with Néel temperatures accessible by experiment.

description: Argument mining is a field in natural language processing that studies the automatic extraction of arguments and the classification of their structure from free text. This is a promising research area with numerous applications, like fact-checking, qualitative assessments of online debates, or analysis of legal documents, but with a set of nontrivial challenges to overcome, the main one being the lack of large language resources for the development of this kind of model. In this work, we propose a research path on a subarea of argument mining that has not been explored as much as some other areas: semi-supervised argument mining. We will explore the adaptation of DISPUTool, a model originally trained on data from the US Presidential Elections Political Debates, to deliberative democracy debates within the ORBIS Project for “augmenting participation, co-creation, trust and transparency in deliberative democracy at all scales”. Our discussion highlights the technical and non-technical challenges of this task and our planned path of action to overcome them.
title: Design Fiction and Participation
title: from Social Dreaming to Speculative Heterotopia
titleType: Subtitle
Creators: name: Darby, Andrew

description: Over the last decade design fiction, the speculative design method, has been cultivated within the design community. It has been increasingly adopted, or at least experimented with, in various areas of government, industry and academia, as new methods to engage with potential futures are sought out. Orienting design practice as an overtly fictive act, design fictions are a form of worldbuilding used variously in the service of rhetoric, innovation and research. The method has been the preserve of designers, researchers and artists working in industry and academia, with a particular nexus between design and HCI. The design fiction works that they create often focus on the normative. Though non-normative perspectives are generally elided in the development of the method, Participatory Design --an approach to design that involves stakeholders as co-creators in design processes-- has, until recently, demonstrated minimal interest in adopting speculative practices. Working from an egalitarian impulse, the thesis explores design fiction as a participatory practice. Taking Research through Design as a methodology, the study offers reflections in, and on, the facilitation and prototyping processes undertaken by the author and others as part of two design projects which worked with older people on government policy in the UK; ProtoPolicy and What If?. Two methods bricolage and black an adapted annotated portfolio were used. The use of bricolage as a method allowed me to develop artefacts as part of an iterative conversation between practice and theory. This process explored and diagrammatically visualised the concept of heterotopia and other relevant theories as a potential theoretical framework supportive of a participatory approach to design fiction. The portfolio gathered together products of the external participatory design fiction projects in a thematic exploration of participation, design fiction and heterotopia. The thesis offers two contributions to knowledge. The first is speculative heterotopia, a theoretical framework to underpin a participatory approach to the design fiction method. The second is a scaffold to guide design facilitators in supporting participants through the possibilities within a design fiction project. The thesis concludes by highlighting issues for facilitators and participant groups created by adopting a participatory approach to design fiction making use of speculative heterotopia.
Good and Evil in Technology as a Question of Christian Values
Creators: name: Schwarz, Hans
Publisher: name: Universität Regensburg
Year: 1979
Subjects: subject: 230 Theologie, Christentum

description: For many years technological progress was perceived as intrinsically good and necessary. Yet more and more people begin to question whether technology and the notion of progress can actually be called good. Some people even wish to do away with the idea of progress altogether and return to a lifestyle of simplicity. Indeed, what is good or evil in technology can neither be discerned in a piecemeal fashion nor can it be defined a priori. It must rather come to focus from the most universal perspective available to us as that which furthers the whole of humanity or detracts from this goal. Since humanity in its fullest sense can be viewed only in the horizon of eschatological perfection provided by Judeo-Christian tradition, good or evil is that which furthers or hinders the realization of the kingdom of God. Technology can then even be an expression of our attempt to respond to the promise of God's kingdom.
Quantum F_un: the q=1 Limit of Galois Field Quantum Mechanics, Projective Geometry, and the Field with One Element

description: We argue that the q=1 limit of Galois Field Quantum Mechanics, which was constructed on a vector space over the Galois Field F_q=GF(q), corresponds to its `classical limit,' where superposition of states is disallowed. The limit preserves the projective geometry nature of the state space, and can be understood as being constructed on an appropriately defined analogue of a `vector' space over the `field with one element' F_1.

description: We consider the three-dimensional incompressible magneto-hydrodynamic system with fractional powers of the Laplacian. We discover a wide range of spaces where the norm inflation occurs and hence small initial data results are out of reach. The norm inflation occurs not only in scaling invariant (critical) spaces, but also in supercritical, and, surprisingly, subcritical ones.

description: The power factor correction of electrical loads is a problem common to all industrial companies. So, in order to utilize a stable and efficient energy to every society power must be managed properly. In most power systems, a poor power factor resulting from an increasing use of inductive loads is often overlooked. A power factor correction unit would allow the system to restore its power factor close to unity for economical operation Laundry and Toilet Soap Factory of Star Soap and Detergent Industry Private Limited Company is located in Akaki-Kallitti Subcity, specifically in front of the place commonly called Wuha Limat. It produces soaps and detergents. The machines the factory uses are inductive operating with total power of 668.11 KW at an average lagging power factor of 0.8 without capacitor bank. This project assessed the power consumption of a Laundry and Toilet Soap Factory of Star Soap and Detergent Industry Private Limited Company and computed the apparent power at 0.8 lagging power factor and at the desired 0.95 power factor using information obtained from the name plates of the inductive loads at the factory. The result showed that at full capacity, for the 131.8638-KVA apparent power reduction/hour due to the power factor correction, there could have been a saving of 607, 628. 3904 KVA/year.
