description: We address the problem of modeling termination resistances which are largely responsible for the uneven distribution of currents in superconducting cables. For such purpose we present three DC models. In a first model a 0D circuit-like approach considering a continuous E-J relationship is presented. A second model uses the 2D H-Formulation of Maxwell's equations, with a new contribution to the electric field term that takes into account the voltage drop due to termination resistances. A third model, based on the 3D H-Formulation of Maxwell's equations, uses a novel technique to simulate both the termination resistances and the superconducting cable within a compact framework that calculates both contributions using two non-connected domains. Advantages and disadvantages of each model are discussed. Particular applications for which a given model is best fitted are also considered. The models' predictions are in good agreement with experimental results for a stacked-tape cable composed of 4 HTS tapes. Overall, this work presents a palette of three different numerical tools for calculating the current distribution in cables composed of multiples tapes, where the termination resistance is also taken into account. The choice of one model over another depends on the particular application and on the degree of precision needed

description: We hypothesize that if election results are manipulated or forged, then, due to the well-known human attraction to round numbers, the frequency of reported round percentages can be increased. To test this hypothesis, we analyzed raw data from seven federal elections held in the Russian Federation during the period from 2000 to 2012 and found that in all elections since 2004 the number of polling stations reporting turnout and/or leader's result expressed by an integer percentage (as opposed to a fractional value) was much higher than expected by pure chance. Monte Carlo simulations confirmed high statistical significance of the observed phenomenon, thereby suggesting its man-made nature. Geographical analysis showed that these anomalies were concentrated in a specific subset of Russian regions which strongly suggests its orchestrated origin. Unlike previously proposed statistical indicators of alleged electoral falsifications, our observations can hardly be explained differently but by a widespread election fraud.

New Trends in Parallel and Distributed Simulation: from Many-Cores to Cloud Computing

description: Recent advances in computing architectures and networking are bringing parallel computing systems to the masses so increasing the number of potential users of these kinds of systems. In particular, two important technological evolutions are happening at the ends of the computing spectrum: at the "small" scale, processors now include an increasing number of independent execution units (cores), at the point that a mere CPU can be considered a parallel shared-memory computer; at the "large" scale, the Cloud Computing paradigm allows applications to scale by offering resources from a large pool on a pay-as-you-go model. Multi-core processors and Clouds both require applications to be suitably modified to take advantage of the features they provide. In this paper, we analyze the state of the art of parallel and distributed simulation techniques, and assess their applicability to multi-core architectures or Clouds. It turns out that most of the current approaches exhibit limitations in terms of usability and adaptivity which may hinder their application to these new computing architectures. We propose an adaptive simulation mechanism, based on the multi-agent system paradigm, to partially address some of those limitations. While it is unlikely that a single approach will work well on both settings above, we argue that the proposed adaptive mechanism has useful features which make it attractive both in a multi-core processor and in a Cloud system. These features include the ability to reduce communication costs by migrating simulation components, and the support for adding (or removing) nodes to the execution architecture at runtime. We will also show that, with the help of an additional support layer, parallel and distributed simulations can be executed on top of unreliable resources.

description: In this paper we analyze the large-time behavior of the augmented Burgers equation. We first study the well-posedness of the Cauchy problem and obtain $L^1$-$L^p$ decay rates. The asymptotic behavior of the solution is obtained by showing that the influence of the convolution term $K*u_{xx}$ is the same as $u_{xx}$ for large times. Then, we propose a semi-discrete numerical scheme that preserves this asymptotic behavior, by introducing two correcting factors in the discretization of the non-local term. Numerical experiments illustrating the accuracy of the results of the paper are also presented.

description: Air pollution is a major health risk factor worldwide. Regular short- and long-time exposures to ambient particulate matter (PM) promote various diseases and can lead to premature death. Therefore, in Germany, air quality is assessed continuously at approximately 400 measurement sites. However, knowledge about this intermediate distribution is either unknown or lacks a high spatial–temporal resolution to accurately determine exposure since commonly used chemical transport models are resource intensive. In this study, we present a method that can provide information about the ambient PM concentration for all of Germany at high spatial (100 m × 100 m) and hourly resolutions based on freely available data. To do so we adopted and optimised a method that combined land use regression modelling with a geostatistical interpolation technique using ordinary kriging. The land use regression model was set up based on CORINE (Coordination of Information on the Environment) land cover data and the Germany National Emission Inventory. To test the model’s performance under different conditions, four distinct data sets were used. (1) From a total of 8760 (365 × 24) available h, 1500 were randomly selected. From those, the hourly mean concentrations at all stations (ca. 400) were used to run the model (n = 566,326). The leave-one-out cross-validation resulted in a mean absolute error (MAE) of 7.68 μg m−3 and a root mean square error (RMSE) of 11.20 μg m−3. (2) For a more detailed analysis of how the model performs when an above-average number of high values are modelled, we selected all hourly means from February 2011 (n = 256,606). In February, measured concentrations were much higher than in any other month, leading to a slightly higher MAE of 9.77 μg m−3 and RMSE of 14.36 μg m−3, respectively. (3) To enable better comparability with other studies, the annual mean concentration (n = 413) was modelled with a MAE of 4.82 μg m−3 and a RMSE of 6.08 μg m−3. (4) To verify the model’s capability of predicting the exceedance of the daily mean limit value, daily means were modelled for all days in February (n = 10,845). The exceedances of the daily mean limit value of 50 μg m−3 were predicted correctly in 88.67% of all cases. We show that modelling ambient PM concentrations can be performed at a high spatial–temporal resolution for large areas based on open data, land use regression modelling, and kriging, with overall convincing results. This approach offers new possibilities in the fields of exposure assessment, city planning, and governance since it allows more accurate views of ambient PM concentrations at the spatial–temporal resolution required for such assessments.

description: Analysis of random censored life-time data along with some related stochastic covariables is of great importance in many applied sciences like medical research, population studies and planning etc. The parametric estimation technique commonly used under this set-up is based on the efficient but non-robust likelihood approach. In this paper, we propose a robust parametric estimator for the censored data with stochastic covariates based on the minimum density power divergence approach. The resulting estimator also has competitive efficiency with respect to the maximum likelihood estimator under pure data. The strong robustness property of the proposed estimator with respect to the presence of outliers is examined and illustrated through an appropriate simulation study in the context of censored regression with stochastic covariates. Further, the theoretical asymptotic properties of the proposed estimator are also derived in terms of a general class of M-estimators based on the estimating equation.

description: We provide two examples of smooth projective surfaces of tame CM type, by showing that any parameter space of isomorphism classes of indecomposable ACM bundles with fixed rank and determinant on a rational quartic scroll in projective 5-space is either a single point or a projective line. For surfaces of minimal degree and wild CM type, we classify rigid Ulrich bundles as Fibonacci extensions. For the rational normal scrolls S(2,3) and S(3,3), a complete classification of rigid ACM bundles is given in terms of the action of the braid group in three strands.

The congruence $η^{\ast}$ on semigroups

Publisher: name: arXiv
Year: 2014
Subjects: subject: Group Theory (math.GR)

description: In this paper we define a congruence $η^{\ast}$ on semigroups. For the finite semigroups $S$, $η^{\ast}$ is the smallest congruence relation such that $S/η^{\ast}$ is a nilpotent semigroup (in the sense of Malcev). In order to study the congruence relation $η^{\ast}$ on finite semigroups, we define a $\textbf{CS}$-diagonal finite regular Rees matrix semigroup. We prove that, if $S$ is a $\textbf{CS}$-diagonal finite regular Rees matrix semigroup then $S/η^{\ast}$ is inverse. Also, if $S$ is a completely regular finite semigroup, then $S/η^{\ast}$ is a Clifford semigroup. We show that, for every non-null principal factor $A/B$ of $S$, there is a special principal factor $C/D$ such that every element of $A\setminus B$ is $η^{\ast}$-equivalent with some element of $C\setminus D$. We call the principal factor $C/D$, the $η^{\ast}$-root of $A/B$. All $η^{\ast}$-roots are $\textbf{CS}$-diagonal. If certain elements of $S$ act in the special way on the $\textbf{R}$-classes of a $\textbf{CS}$-diagonal principal factor then it is not an $η^{\ast}$-root. Some of these results are also expressed in terms of pseudovarieties of semigroups.

description: The domain of outer communication of five-dimensional asymptotically flat stationary spacetimes may possess non-trivial 2-cycles. We discuss how this may lead to a gross violation of black hole uniqueness, beyond the existence of black rings, even for solutions with two commuting rotational symmetries. We illustrate this with a simple example in minimal supergravity; a four parameter family of supersymmetric black hole solutions, with spherical horizon topology and a 2-cycle in the exterior. We show there are black holes in this family with identical conserved changes to the BMPV black hole, thereby demonstrating black hole non-uniqueness in this context. We find a decoupling limit of this family of black holes that yields spacetimes asymptotic to the near-horizon geometry of a BMPV black hole which contain a black hole and an exterior 2-cycle.

description: An identifying code of a graph is a subset of its vertices such that every vertex of the graph is uniquely identified by the set of its neighbours within the code. We show a dichotomy for the size of the smallest identifying code in classes of graphs closed under induced subgraphs. Our dichotomy is derived from the VC-dimension of the considered class C, that is the maximum VC-dimension over the hypergraphs formed by the closed neighbourhoods of elements of C. We show that hereditary classes with infinite VC-dimension have infinitely many graphs with an identifying code of size logarithmic in the number of vertices while classes with finite VC-dimension have a polynomial lower bound. We then turn to approximation algorithms. We show that the problem of finding a smallest identifying code in a given graph from some class is log-APX-hard for any hereditary class of infinite VC-dimension. For hereditary classes of finite VC-dimension, the only known previous results show that we can approximate the identifying code problem within a constant factor in some particular classes, e.g. line graphs, planar graphs and unit interval graphs. We prove that it can be approximate within a factor 6 for interval graphs. In contrast, we show that on C_4-free bipartite graphs (a class of finite VC-dimension) it cannot be approximated to within a factor of c.log(|V|) for some c>0.

description: Classical mechanics, relativity, electrodynamics and quantum mechanics are often depicted as separate realms of physics, each with its own formalism and notion. This remains unsatisfactory with respect to the unity of nature and to the necessary number of postulates. We uncover the intrinsic connection of these areas of physics and describe them using a common symplectic Hamiltonian formalism. Our approach is based on a proper distinction between variables and constants, i.e. on a basic but rigorous ontology of time. We link these concept with the obvious conditions for the possibility of measurements. The derived consequences put the measurement problem of quantum mechanics and the Copenhagen interpretation of the quantum mechanical wavefunction into perspective. According to our (onto-) logic we find that spacetime can not be fundamental. We argue that a geometric interpretation of symplectic dynamics emerges from the isomorphism between the corresponding Lie algebra and the representation of a Clifford algebra. Within this conceptional framework we derive the dimensionality of spacetime, the form of Lorentz transformations and of the Lorentz force and fundamental laws of physics as the Planck-Einstein relation, the Maxwell equations and finally the Dirac equation.

We pay particular attention to the maximally unipotent case, where $β_{1}=\ldots=β_{n}=1$, and present a theorem that enables us to determine the form of the corresponding monodromy matrices in the case where $(X-e^{-2πiα_{1}})\cdots (X-e^{-2πiα_{n}})$ is a product of cyclotomic polynomials.

description: We introduce a family of domino tilings that includes tilings of the Aztec diamond and pyramid partitions as special cases. These tilings live in a strip of $\mathbb{Z}^2$ of the form $1 \leq x-y \leq 2\ell$ for some integer $\ell \geq 1$, and are parametrized by a binary word $w\in\{+,-\}^{2\ell}$ that encodes some periodicity conditions at infinity. Aztec diamond and pyramid partitions correspond respectively to $w=(+-)^\ell$ and to the limit case $w=+^\infty-^\infty$. For each word $w$ and for different types of boundary conditions, we obtain a nice product formula for the generating function of the associated tilings with respect to the number of flips, that admits a natural multivariate generalization. The main tools are a bijective correspondence with sequences of interlaced partitions and the vertex operator formalism (which we slightly extend in order to handle Littlewood-type identities). In probabilistic terms our tilings map to Schur processes of different types (standard, Pfaffian and periodic). We also introduce a more general model that interpolates between domino tilings and plane partitions.

description: Evidence‐based psychological treatments for trichotillomania (TTM) can be effective; however, relapse is common and consumers have indicated poor satisfaction with treatment outcomes. The aim of this study was to identify participants' perspectives of critical factors associated with short‐ and long‐term recovery following their brief, intensive peer‐support retreat for TTM. A mixed methods longitudinal design was used to evaluate a 3‐day residential peer‐support retreat attended by eight women who self‐referred into the retreat. Semi‐structured interviews were conducted at post‐retreat (n = 6) and 12‐month follow‐up (n = 5). Self‐report measures of symptom severity, mood and quality of life were completed at baseline (n = 7), post‐retreat (n = 6), 6‐month follow‐up (n = 5) and 12‐month follow‐up (n = 5). An inductive thematic analysis was performed to identify themes within the interview transcripts. Quantitative outcome data was used to confirm, challenge, provide context for, and link qualitative findings within the broader literature. Quantitative outcome data demonstrated reduced TTM severity from baseline to post‐retreat. By 6‐month follow‐up, symptoms had relapsed to baseline levels. Participants' perspectives of factors associated with recovery immediately after the retreat included group‐based processes (e.g., sharing, normalisation, safety, and enhanced motivation/accountability) and individual processes (e.g., readiness for change, self‐regulation skills). The qualitative and quantitative data conveyed similar outcomes at both post‐retreat and 12‐month follow‐up. Brief, immersive peer‐support retreats for TTM may facilitate equivalent symptom reductions as longer, therapist‐delivered cognitive behavioural treatments for some individuals.

description: To a pair of elliptic curves, one can naturally attach two K3 surfaces: the Kummer surface of their product and a double cover of it, called the Inose surface. They have prominently featured in many interesting constructions in algebraic geometry and number theory. There are several more associated elliptic K3 surfaces, obtained through base change of the Inose surface; these have been previously studied by Kuwata. We give an explicit description of the geometric Mordell-Weil groups of each of these elliptic surfaces in the generic case (when the elliptic curves are non-isogenous). In the non-generic case, we describe a method to calculate explicitly a finite index subgroup of the Mordell-Weil group, which may be saturated to give the full group. Our methods rely on several interesting group actions, the use of rational elliptic surfaces, as well as connections to the geometry of low degree curves on cubic and quartic surfaces. We apply our techniques to compute the full Mordell-Weil group in several examples of arithmetic interest, arising from isogenous elliptic curves with complex multiplication, for which these K3 surfaces are singular.

description: The efficacy of mindfulness‐based interventions for post‐traumatic stress disorder has not been demonstrated clearly nor have processes of change been examined extensively in the context of post‐traumatic stress. Decreases in trauma‐related rumination is one possible mechanism underlying the positive effect of mindfulness on reducing post‐trauma symptomatology. The present study investigated whether brief mindfulness training reduced post‐traumatic intrusions, testing the mediating role of trauma‐related rumination. Sixty female university students viewed a film clip depicting scenes of physical and sexual violence. They then listened to a short audio of either a mindfulness or relaxation exercise and were instructed to use the respective techniques to manage film‐related rumination in‐session and over the following week. The mindfulness induction decreased vividness of intrusions, but not intrusion frequency or associated distress, nor post‐traumatic stress symptoms or film‐related rumination. No mediation of film‐related rumination was found. Preliminary evidence was found for the effect of mindfulness training on reducing vividness of trauma intrusions, but not intrusion frequency or associated distress. However, the current study failed to observe increases in mindfulness following brief training. Despite this, trait mindfulness predicted lower levels of post‐traumatic stress symptoms. Future research should examine whether trauma‐related rumination constitutes a process of change using more intensive training of mindfulness‐based interventions for post‐traumatic stress disorder. Theoretical and clinical implications are discussed.

description: We present a new method for inferring complexity properties for a class of programs in the form of flowcharts annotated with loop information. Specifically, our method can (soundly and completely) decide if computed values are polynomially bounded as a function of the input; and similarly for the running time. Such complexity properties are undecidable for a Turing-complete programming language, and a common work-around in program analysis is to settle for sound but incomplete solutions. In contrast, we consider a class of programs that is Turing-incomplete, but strong enough to include several challenges for this kind of analysis. For a related language that has well-structured syntax, similar to Meyer and Ritchie's LOOP programs, the problem has been previously proved to be decidable. The analysis relied on the compositionality of programs, hence the challenge in obtaining similar results for flowchart programs with arbitrary control-flow graphs. Our answer to the challenge is twofold: first, we propose a class of loop-annotated flowcharts, which is more general than the class of flowcharts that directly represent structured programs; secondly, we present a technique to reuse the ideas from the work on tructured programs and apply them to such flowcharts. The technique is inspired by the classic translation of non-deterministic automata to regular expressions, but we obviate the exponential cost of constructing such an expression, obtaining a polynomial-time analysis. These ideas may well be applicable to other analysis problems.

description: The study examined the impact of Chief Executive Officer (CEO) characteristics on corporate tax planning of listed financial service firms in Nigeria from 2018-2022. The specific objective was to ascertain the impact of CEO age on corporate tax planning of listed firms in Nigeria; examine the influence of CEO tenure on corporate tax planning of listed firms in Nigeria and to investigate the impact of CEO financial expertise on corporate tax planning of listed firms in Nigeria. The study employed the ex post factor research design and descriptive and inferential statistics were employed to summarize and draw inference on the population studied. The ordinary least square was used to estimate the model of the study. The result of the analysis revealed that CEO age and CEO financial expertise have positive impact on corporate tax planning of listed financial firms in Nigeria. The study also found that CEO tenure have negative impact on corporate tax planning of listed financial firms in Nigeria. The study recommended that firms in the financial sector should sustain the policy of employing CEOs that are above 50 years, because they have the experience in handling tax related issues.

description: Recent craving research has focused on individuals' beliefs about cravings. Yet, measures about craving beliefs have rarely been compared with other craving belief measures or measures of craving itself. We aimed to develop a craving metacognition measure with a simple factor structure that could be used by people with a range of alcohol use patterns. This article introduces the Craving Metacognition Scale, a measure of individuals' craving metacognitions. Items were generated based on specific beliefs and attitudes related to craving and drinking, sourced from existing questionnaires and edited to emphasise metacognitive appraisal. Two samples tested the scale: one of individuals seeking treatment for alcohol use issues (n = 115) and the other of undergraduate students who drank regularly (n = 92). The items were refined based on contribution to the total score and divergence from existing measures. The final 13‐item scale showed strong internal consistency (α = .93) and good convergence with existing measures, such as the Jellinek Alcohol Craving Questionnaire‐now (Pearson's r = .698) and the Metacognition Questionnaire for Alcohol Abusers subscales (between r = .602 and r = .811). The Craving Metacognition Scale shows preliminary evidence of psychometric validity. It has a simple factor structure that measures craving metacognitions reported by individuals with a range of drinking habits.

title: An Investigation into the Effects of Classroom Acoustics on Teachers’ Voices
Creators: name: Durup, N D
Publisher: name: London South Bank University

description: The acoustic design of classrooms has traditionally focused on pupils hearing the
teacher. There is a need for guidance on the consideration of voice ergonomics for
teachers in classroom design.
This project undertook measurements of teachers’ voices in classrooms with different
acoustic properties to examine possible relationships between voice parameters and
classroom acoustics. The mean voice level measured was classified as ‘loud’ (based on
guidance values) and the participants spoke for a large proportion of the day (average
21%).
Those teaching in rooms with higher unoccupied noise levels spoke with a higher
sound level. There was a significant, moderate, positive correlation between voice
levels in female participants and the unoccupied noise levels in the same region of the
noise spectrum as the fundamental frequency of the female voice. There were signs of
a similar relationship for male participants. This indicated that the control of low
frequency noise levels and reverberation times (not currently covered by schools
guidance documents in England) may be important in reducing voice levels and the
associated vocal risks.
An online survey was also undertaken which gathered 153 responses and included
questions on voice problems, voice training, classroom acoustics and general health.
The respondents reported a number of interesting findings. 66% reported having
experienced voice problems, with many continuing to work despite these problems. A
relatively small proportion of respondents had received voice training (41%), and many
reported shouting or raising their voice.
There were greater rates of reported voice problems in teachers of young children and
those teaching in open plan classrooms. Subjectively the main acoustic issues for
teachers were inadequate internal sound insulation and excessive reverberation.
External noise intrusion was not reported as significant.

description: Clinical placement is an essential aspect of student training in professional postgraduate psychology. However, students can be exposed to risk during clinical placement. Further, anecdotal evidence suggests that barriers may hinder formal reporting of adverse events occurring during placement. The objective of this study was to investigate the incidence and nature of psychology students' exposure to risk during clinical placement. This study also sought to explore key stakeholders' perceptions of risks to students engaging in placement. A sequential explanatory mixed‐method design was utilised. The quantitative element of the study involved a questionnaire capturing the experiences of 70 students currently undertaking clinical psychology placement in healthcare services within Australia. This was followed by qualitative semi‐structured interviews with 10 industry‐based stakeholders associated with clinical placements across seven Australian universities. Preliminary evidence indicates that psychology students can experience adverse events while on clinical placement, and that industry‐based stakeholders can also encounter professional risk resulting from student contact. Low uptake of formal incident reports among students was demonstrated. The quality of risk‐related training was shown to vary across the industry, indicating a need for streamlined training approaches to risk management. Finally, strategies to support students and supervisors were raised. Novice students may be inadequately prepared for the risks arising in unpredictable clinical placement milieu. They may also be unaware of their rights and avenues for reporting. Further support and resources designed to equip health services and universities for student exposure to risk during placement is warranted.

title: Investigation of a new clinical
method of measuring amplitude of
accommodation
Creators: name: Burns, D H
Publisher: name: London South Bank University
Year: 2017

description: Amplitude of Accommodation (AoA) is the extent of the eye’s ability to accommodate, or
focus over a range of distances. This thesis describes the mechanism of accommodation
and reviews the literature concerning the measurement of accommodation’s amplitude,
its maximum range. The reasons for measuring the amplitude of accommodation, in
routine clinical practice, are outlined. The aim of this study is to investigate the accuracy
of a new clinical method of measuring amplitude of accommodation and to compare it to
the prevalent method.
Methods by which the amplitude of accommodation has been measured clinically are
described and compared. Each method has inherent sources of error and these are
examined individually to show how they affect the results of measurement. The new
method of measurement, developed by the author, is introduced. Its basis, which may
lead to a redefinition of amplitude of accommodation, is explained and contrasted with
the rationale of existing methods. Experimental work is reported comparing accuracy of
measurement using the new method (the TRU) with that of the prevalent method (Push-
Up with the RAF Rule). Two techniques for using the TRU, distance-measurement and
acuity-measurement, were examined and distance-measurement was shown to be more
precise.
The method-comparison was by repeated measures of results with both methods and
with those of an objective reference method, the WAM-5500 autorefractor. The estimated
95% limits of agreement between the two test methods spanned 6.36 D (dioptres). The
disparity of results appeared due more to differences between the test methods’ trueness
than their precision. The RAF Rule gave results that averaged 2.10 D higher than results
with the TRU and 2.19 D higher than results with the WAM-5500 autorefractor.
Measurements of AoA with the autorefractor were 67% more repeatable than
measurements with the TRU and 114% more repeatable than measurements with the
RAF Rule, although of questionable trueness.
The estimated 95% limits of agreement of reproducibility between sessions spanned
6.57D for the established method but 2.89 D for the new method, and reproducibility
between investigators similarly spanned 5.10 D for the established method and 2.56 D
for the new method.
The significance of these findings for clinical vision science is discussed and examined
in the light of theoretical considerations of each method’s validity. Suggestions are made
for improving the accuracy of measurement of the amplitude of accommodation, which
should improve the reliability of normative values in current clinical use.
