description: We introduce the Tesler polytope Tes_n(a_1,a_2,...,a_n), whose integer points are the Tesler matrices of size n with nonnegative integer hook sums a_1,a_2,...,a_n. We show that Tes_n(a) is a flow polytope and therefore the number of Tesler matrices is counted by the type A_n Kostant partition function evaluated at (a_1,a_2,...,a_n,-a_1-...-a_n). We describe the faces of this polytope in terms of "Tesler tableaux" and characterize when the polytope is simple. We prove that the h-vector of Tes_n(a) when all a_i>0 is given by the Mahonian numbers and calculate the volume of Tes_n(1,1,...,1) to be a product of consecutive Catalan numbers multiplied by the number of standard Young tableaux of staircase shape.

Characterizing the stabilization size for semi-implicit Fourier-spectral method to phase field equations
Creators: name: Li, Dong

Publisher: name: arXiv

Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: Recent results in the literature provide computational evidence that stabilized semi-implicit time-stepping method can efficiently simulate phase field problems involving fourth-order nonlinear dif- fusion, with typical examples like the Cahn-Hilliard equation and the thin film type equation. The up-to-date theoretical explanation of the numerical stability relies on the assumption that the deriva- tive of the nonlinear potential function satisfies a Lipschitz type condition, which in a rigorous sense, implies the boundedness of the numerical solution. In this work we remove the Lipschitz assumption on the nonlinearity and prove unconditional energy stability for the stabilized semi-implicit time-stepping methods. It is shown that the size of stabilization term depends on the initial energy and the perturba- tion parameter but is independent of the time step. The corresponding error analysis is also established under minimal nonlinearity and regularity assumptions.

description: During the last two decades, great efforts have been devoted to the calculation of the local theta correspondence for reductive dual pairs. However, uniform formulas remain elusive for real dual pairs of type I. The purpose of this paper is twofold: to formulate an explicit version of induction principle for dual pairs $(O(p,q),Sp(2n,\mathbb{R}))$ with $p + q$ even, and to apply it to obtain a complete and explicit description of the local theta correspondence when $p + q = 4$. Our approach is very elementary by analysis on the infinitesimal characters and K-types under the correspondence.

description: Problem solving tasks are one of the topics of investigation within the field of STEM and educational engineering involving children. However, young children have received much more little attention. Accordingly, this paper explores the issues discussed by preschool children during engineering activities. We focus on the issues participants discuss during three building problem solving proposed to preschool children at a kindergarten. The activities were audio-video recorded and the argumentative discussions were identified and transcribed. The argumentative analysis focused on different elements, such as the issuesoccurring in each argumentative episode, the standpoints, the arguments, and the argumentative structure. In particular, to explore the issues and their role in problem solving activities, three illustrative cases are presented. The findings show, from an argumentative perspective, a variety of issues explored by children in solving problems around building tasks. The task presented by the adult as a building activity represents something more for the participant children: for example, the children focus on the technical components to overcome possible obstacles, they refer to the collaboration with peers, to the possession of objects or to the utility of the working activities. As preschool children’s engineering work appears as a complex activity, the present study highlights the value of analyzing the issues that are discussed by preschool children during building activities.

description: Image denoising algorithms are evaluated using images corrupted by artificial noise, which may lead to incorrect conclusions about their performances on real noise. In this paper we introduce a dataset of color images corrupted by natural noise due to low-light conditions, together with spatially and intensity-aligned low noise images of the same scenes. We also introduce a method for estimating the true noise level in our images, since even the low noise images contain small amounts of noise. We evaluate the accuracy of our noise estimation method on real and artificial noise, and investigate the Poisson-Gaussian noise model. Finally, we use our dataset to evaluate six denoising algorithms: Active Random Field, BM3D, Bilevel-MRF, Multi-Layer Perceptron, and two versions of NL-means. We show that while the Multi-Layer Perceptron, Bilevel-MRF, and NL-means with soft threshold outperform BM3D on gray images with synthetic noise, they lag behind on our dataset.

The special case of eventually periodic operators solves an open problem of Simon [25, D.2.7]. We also solve the inverse resonance problem: it is shown that an operator is completely determined by the set of its eigenvalues and resonances, and we provide necessary and sufficient conditions on their configuration for such an operator to exist.

Higgs-like mechanism for spontaneous spacetime symmetry breaking

Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: The study of spontaneous breakdown of spacetime symmetries leads to the discovery of another type of Higgs mechanism operating in a chiral SU(2) model. Some of the Nambu-Goldstone vector mesons emergent from simultaneous violations of gauge and Lorentz symmetries are, in this case, absorbed by a left-handed doublet and endow one of the fermions with a right-handed state, while another part becomes emergent as photons. Accordingly, this mechanism allows a chiral fermion to acquire a mass, and it may enable the emergent theory to reproduce the electromagnetism equivalent to the QED sector in the standard theory. It is also mentioned that the "fermion-boson puzzle" known in the presence of a 't Hooft--Polyakov monopole does not exist in our theory.

description: Capillary glass viscometers are widely used and their method is well established worldwide for traceable measurement of the kinematic viscosity to the SI units. However, this technique does not allow in-line measurement of the dynamic viscosity in flow applications, which is important for the process-oriented information about the dynamic viscosity of the liquid. The micro pipe viscometers enable the characterization of liquids under flow conditions and the direct calibration of devices that measure dynamic viscosity under flow conditions or investigation of the influence of dynamic viscosity on the performance of flow devices. This report describes the primary standards developed by NEL, RISE and METAS based on micro pipe viscometers for the in-line measurement of the dynamic viscosities. Their stated measurement uncertainties have been validated by the measurements of the dynamic viscosity of the liquids A – H and their consistency has been demonstrated in this report.
title: Kitchen-table UK charities funding educational projects in sub-Saharan Africa: issues of sustainability
Creators: name: FitzGerald, J R S
Publisher: name: London South Bank University
Year: 2018

description: My research addresses the question:
How can UK kitchen-table charities that focus their efforts on educational projects in sub-Saharan Africa mitigate factors that negatively affect the sustainability of their work?
Kitchen-table charities are managed by volunteers that meet in the home of one of the trustees, usually around the kitchen table. My professional experience as a founder member and Chair of Trustees of a kitchen-table charity, whose mission is to provide secondary education in a remote area of Tanzania, is integral to this research. Despite the contribution of small charities to the funding of education at grass-roots level in sub-Saharan Africa, research into their experiences and challenges appears non-existent.
My study has three objectives: to identify issues that affect the long-term sustainability of kitchen-table charities, to investigate and record ways of building resilience to these issues and to produce an original research information booklet, based on my findings, as a practical tool for practitioners.
I adopted action research as the methodological framework and used grounded theory as my analytical approach to the data. Key findings have been drawn from the generation of sub-categories that I connected to core-categories and include: lack of an exit plan; problems relevant to management at a distance; corruptive practices in-country; no succession plan. Issues of sustainability can be mitigated with increased awareness and thought for the preparedness of problems.
My research has shown that small charities encounter common issues relating to sustainability. I devised a template based on an action research model to assist with problem-solving and forward planning strategies. This template is included in a Research Information Booklet entitled A Practitioner’s Handbook (Appendix 1). The booklet contains the findings of my research and has been welcomed by the participants and other interested trustees.

description: Diluted mean-field models are graphical models in which the geometry of interactions is determined by a sparse random graph or hypergraph. Based on a nonrigorous but analytic approach called the "cavity method", physicists have predicted that in many diluted mean-field models a phase transition occurs as the inverse temperature grows from $0$ to $\infty$ [Proc. National Academy of Sciences 104 (2007) 10318-10323]. In this paper, we establish the existence and asymptotic location of this so-called condensation phase transition in the random hypergraph $2$-coloring problem.

description: One-dimensional time-reversal invariant topological superconducting wires of the symmetry class DIII exhibit exotic physics which can be exploited to realize the set of universal operations in topological quantum computing. However, the verification of DIII-class physics in conventional condensed matter materials is highly nontrivial due to realistic constraints. Here we propose a symmetry-protected hard-core boson simulator of the one-dimensional DIII topological superconductor. By using the developed dispersive dynamic modulation approach, not only the faithful simulation of this new type of spinful superconducting chains is achieved, but also a set of universal quantum gates can be realized with the computational basis formed by the degenerate ground states that are topologically protected against random local perturbations. Physical implementation of our scheme based on a Josephson quantum circuit is presented, where our detailed analysis pinpoints that this scheme is experimentally feasible with the state-of-the-art technology.

Drivers for inter-city innovation networks across Chinese cities: Modelling physical versus intangible effects
Creators: name: Scherngell, Thomas
Publisher: name: Zenodo
Year: 2022

description: This study aims to explore the role of intangible drivers in the formation of inter-city innovation network in developing countries like China. We mobilize original data on inter- city innovation networks reflected in co-patents collected for the time period 2007-2018. A network analytical approach is used to explore the evolution of the innovation networks, while we specify spatial interaction models to estimate the relationship between collaboration intensity and intangible characteristics of the cities. The initial results are promising. First, ICT gap among cities has negative effect, while the ICT development itself shows prominent role in promoting cross-region innovation collaboration. Second, the study reveals the existence of preferential attachment; the network structure has an increasingly positive effect. The result has great importance for analysing future innovation collaboration pattern in China. As the Chinese government has launched a wave of digital infrastructure construction since 2020. Especially, it pays much attention to the balanced development of digitalization in western regions. In 2022, China approved the construction of eight national computing hubs, of which five hubs are located in the western region. ICT development will reshape Chinese economic geography in the near future. The balanced development of ICT may give periphery regions more opportunities to access external knowledge. Apart from this, the network structural effect gives some thinking on how to change the unbalanced collaboration among regions in China. Like what is happening in some leading regions like Yangtze River Delta, local government should take more measures to build cross-region innovation platforms and construct cooperation framework agreements to promote coordinated regional innovation.

description: Applications of the Hückel (tight binding) model are ubiquitous in quantum chemistry and solid state physics. The matrix representation of this model is isomorphic to an unoriented vertex adjacency matrix of a bipartite graph, which is also the Laplacian matrix plus twice the identity. In this paper, we analytically calculate the determinant and, when it exists, the inverse of this matrix in connection with the Green's function, $\mathbf{G}$, of the $N\times N$ Hückel matrix. A corollary is a closed form expression for a Harmonic sum (Eq. 12). We then extend the results to $d-$dimensional lattices, whose linear size is $N$. The existence of the inverse becomes a question of number theory. We prove a new theorem in number theory pertaining to vanishing sums of cosines and use it to prove that the inverse exists if and only if $N+1$ and $d$ are odd and $d$ is smaller than the smallest divisor of $N+1$. We corroborate our results by demonstrating the entry patterns of the Green's function and discuss applications related to transport and conductivity.

Multi-locality and fusion rules on the generalized structure functions in two-dimensional and three-dimensional Navier-Stokes turbulence
Creators: name: Gkioulekas, Eleftherios
Publisher: name: arXiv
Year: 2014
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: Using the fusion rules hypothesis for three-dimensional and two-dimensional Navier-Stokes turbulence, we generalize a previous non-perturbative locality proof to multiple applications of the nonlinear interactions operator on generalized structure functions of velocity differences. We shall call this generalization of non-perturbative locality to multiple applications of the nonlinear interactions operator "multilocality". The resulting cross-terms pose a new challenge requiring a new argument and the introduction of a new fusion rule that takes advantage of rotational symmetry. Our main result is that the fusion rules hypothesis implies both locality and multilocality in both the IR and UV limits for the downscale energy cascade of three-dimensional Navier-Stokes turbulence and the downscale enstrophy cascade and inverse energy cascade of two-dimensional Navier-Stokes turbulence. We stress that these claims relate to non-perturbative locality of generalized structure functions on all orders, and not the term by term perturbative locality of diagrammatic theories or closure models that involve only two-point correlation and response functions.

description: Quantum technology promises revolutionary advantages in information processing and transmission compared to classical technology; however, determining which specific resources are needed to surpass the capabilities of classical machines often remains a nontrivial problem. To address such a problem, one first needs to establish the best classical solutions, which set benchmarks that must be beaten by any implementation claiming to harness quantum features for an enhanced performance. Here we introduce and develop a self-contained formalism to obtain the ultimate, generally probabilistic benchmarks for quantum information protocols including teleportation and approximate cloning, with arbitrary ensembles of input states generated by a group action, so-called Gilmore-Perelomov coherent states. This allows us to construct explicit fidelity thresholds for the transmission of multimode Gaussian and non-Gaussian states of continuous variable systems, as well as qubit and qudit pure states drawn according to nonuniform distributions on the Bloch hypersphere, which accurately model the current laboratory facilities. The performance of deterministic classical procedures such as square-root measurement strategies is further compared with the optimal probabilistic benchmarks, and the state-of-the-art performance of experimental quantum implementations against our newly derived thresholds is discussed. This work provides a comprehensive collection of directly useful criteria for the reliable certification of quantum communication technologies.

title: Ein linguistischer Vergleich der deutschen und chinesischen Fernsehwerbung
Creators: name: Xu, Ying
Publisher: name: UNSPECIFIED
Year: 2020

description: In Zeiten der Globalisierung setzen international agierende Unternehmen Werbemaßnahmen weltweit ein. Um erfolgreiche internationale Werbekampagnen zu erzielen, werden nicht nur Informationen über angebotene Produkte über die Werbung vermittelt, sondern Produkt- und Markenimages mittels emotionaler Mehrwerte etabliert. Diese sind jedoch in hohem Grade kulturspezifisch, was die Bewerbung globaler Marken vor eine Herausforderung stellt. Hieraus resultiert die Forschungsfrage der vorliegenden Arbeit, nämlich inwiefern sich in internationaler Werbung Kulturspezifika vs. Merkmale von Standardisierung niederschlagen. Die Antwort wird in der vorliegenden Arbeit über einen kontrastiven Vergleich deutscher und chinesischer Fernsehwerbung aus linguistischer Perspektive gegeben. Die exemplarische Untersuchung basiert auf internationalen Fernsehwerbungen, in denen die gleichen oder gleichartigen Markenartikel des täglichen Gebrauchs beworben werden, d.h. auf deutsch-chinesischen Spot-Paaren. Dabei werden sowohl bildliche Darstellung als auch sprachliche Formen analysiert. Die Bildanalyse befasst sich mit der Inszenierung der Drehorte und den auftretenden Personen. Der Vergleich der deutschen und chinesischen Werbesprache bezieht sich auf die lexikalische und syntaktische Ebene sowie auf textsortenspezifische Sprachstile. Dabei werden Gemeinsamkeiten als Formen von Standardisierung von Werbeaktivitäten und Unterschiede auf Basis sprachlicher Gesetzmäßigkeiten und soziokultureller Hintergründe erklärt. Die Ergebnisse zeigen, dass international agierende Unternehmen eine Werbestandardisierung in Deutschland und China anstreben, um ein global standardisiertes Produkt- oder Markenimage aufzubauen. Die ebenfalls herausgearbeiteten Merkmale von Differenzierung in der deutschen und chinesischen Fernsehwerbung sind nicht zwangsläufig als Ausdruck von Kulturgebundenheit zu betrachten, sondern können auch effizienten persuasiven Werbestrategien im internationalen Kontext geschuldet sein. Sie lassen sich nicht nur auf kulturelle Hintergründe der deutschen und chinesischen Gesellschaft zurückführen, sondern verweisen auch auf das jeweilige aktuelle gesellschaftliche Umfeld und kulturellen Wandel.

description: We study the hydrodynamic and the hydrostatic behavior of the Simple Symmetric Exclusion Process with \emph{slow boundary}. The term \emph{slow boundary} means that particles can be born or die at the boundary sites, at a rate proportional to $N^{-θ}$, where $θ> 0$ and $N$ is the scaling parameter. In the bulk, the particles exchange rate is equal to $1$. In the hydrostatic scenario, we obtain three different linear profiles, depending on the value of the parameter $θ$; in the hydrodynamic scenario, we obtain that the time evolution of the spatial density of particles, in the diffusive scaling, is given by the weak solution of the heat equation, with boundary conditions that depend on $ θ$. If $θ\in(0,1)$, we get Dirichlet boundary conditions, (which is the same behavior if $θ=0$, see \cite{f}); if $θ=1$, we get Robin boundary conditions; and, if $θ\in(1,\infty)$, we get Neumann boundary conditions.

Topology morphing in composite helical lattices
Creators: name: Carey, Seán
Publisher: name: University of Limerick
Year: 2022
Subjects: Engineering

description: Morphing composite structures present a departure from traditional engineering structures due to their inherent shape changing nature, which can be tailored and optimised in order to reduce structural mass whilst maintaining and even increasing structural stiffness, where desirable. This thesis describes two such morphing structures, the bistable composite helix and the multistable composite cylindrical lattice. While the two structures are similar in composition, both consisting of carbon fibre reinforced polymer strips manufactured to an initial curvature and constrained to a smaller curvature, introducing prestress, they differ in the method in which they are fastened and hence their method of morphing. The bistable composite helix structure consists of composite strips joined by rigid spokes, fixing the helix to a constant radius, thus, as the helix morphs, its radius remains constant and its twist varies. The cylindrical lattice however comprises composite strips, fastened to each other, in a manner whereby as the lattice deploys, its radius decreases and its twist remains constant. The analytical modelling capabilities of both structures is enhanced upon by incorporating thermal strain to the strain energy profile, which allows the morphing behaviour of these structures to be more accurately predicted. Finite element analysis and experimental testing of both structures are performed in order to test the validity of the analytical models developed. This improvement of the modelling capabilities facilitates further morphing behaviours to be enabled within these structures. This thesis focuses on developing a topological morphing mechanism within the composite cylindrical lattice structure. Mechanical fasteners are replaced with permanent magnets in order to enable a reconfigurable joint within the cylindrical lattice structure, hence introducing manually actuated topological morphing. This mechanism is further developed by replacing a set of permanent magnets with electromagnets in order to introduce semi-autonomy of morphing to the system. Extensive characterisation of the cylindrical lattice is performed, focusing on the site of topology morphing, and on the structure globally both pre- and post-topology change, through experimental testing and finite element analysis in order to represent the effects of topology morphing on the cylindrical lattice.

description: The effect of Planck scale quantum geometrical effects on measurements with interferometers is estimated with standard physics, and with a variety of proposed extensions. It is shown that effects are negligible in standard field theory with canonically quantized gravity. Statistical noise levels are estimated in a variety of proposals for non-standard metric fluctuations, and these alternatives are constrained using upper bounds on stochastic metric fluctuations from LIGO. Idealized models of several interferometer system architectures are used to predict signal noise spectra in a quantum geometry that cannot be described by a fluctuating metric, in which position noise arises from holographic bounds on directional information. Predictions in this case are shown to be close to current and projected experimental bounds.

description: Background The aim of this study was to analyze the shoulder functional profile (rotation range of motion [ROM] and strength), upper and lower body performance, and throwing speed of U13 versus U15 male handball players, and to establish the relationship between these measures of physical fitness and throwing speed. Methods One-hundred and nineteen young male handball players (under (U)-13 (U13) [n = 85]) and U15 [n = 34]) volunteered to participate in this study. The participating athletes had a mean background of sytematic handball training of 5.5 ± 2.8 years and they exercised on average 540 ± 10.1 min per week including sport-specific team handball training and strength and conditioning programs. Players were tested for passive shoulder range-of-motion (ROM) for both internal (IR) and external rotation (ER) and isometric strength (i.e., IR and ER) of the dominant/non-dominant shoulders, overhead medicine ball throw (OMB), hip isometric abductor (ABD) and adductor (ADD) strength, hip ROM, jumps (countermovement jump [CMJ] and triple leg-hop [3H] for distance), linear sprint test, modified 505 change-of-direction (COD) test and handball throwing speed (7 m [HT7] and 9 m [HT9]). Results U15 players outperformed U13 in upper (i.e., HT7 and HT9 speed, OMB, absolute IR and ER strength of the dominant and non-dominant sides; Cohen’s d: 0.76–2.13) and lower body (i.e., CMJ, 3H, 20-m sprint and COD, hip ABD and ADD; d: 0.70–2.33) performance measures. Regarding shoulder ROM outcomes, a lower IR ROM was found of the dominant side in the U15 group compared to the U13 and a higher ER ROM on both sides in U15 (d: 0.76–1.04). It seems that primarily anthropometric characteristics (i.e., body height, body mass) and upper body strength/power (OMB distance) are the most important factors that explain the throw speed variance in male handball players, particularly in U13. Conclusions Findings from this study imply that regular performance monitoring is important for performance development and for minimizing injury risk of the shoulder in both age categories of young male handball players. Besides measures of physical fitness, anthropometric data should be recorded because handball throwing performance is related to these measures.

description: We describe a system to transport and identify barium ions produced in liquid xenon, as part of R&D towards the second phase of a double beta decay experiment, nEXO. The goal is to identify the Ba ion resulting from an extremely rare nuclear decay of the isotope $^{136}$Xe, hence providing a confirmation of the occurrence of the decay. This is achieved through Resonance Ionization Spectroscopy (RIS). In the test setup described here, Ba ions can be produced in liquid xenon or vacuum and collected on a clean substrate. This substrate is then removed to an analysis chamber under vacuum, where laser-induced thermal desorption and RIS are used with time-of-flight (TOF) mass spectroscopy for positive identification of the barium decay product.

description: We give a necessary and sufficient condition for extremality of a supermodular function based on its min-representation by means of (vertices of) the corresponding core polytope. The condition leads to solving a certain simple linear equation system determined by the combinatorial core structure. Our result allows us to characterize indecomposability in the class of generalized permutohedra. We provide an in-depth comparison between our result and the description of extremality in the supermodular/submodular cone achieved by other researchers.
TASEP on parallel tracks: effects of mobile bottlenecks in fixed segments

description: We study the flux of totally asymmetric simple exclusion processes (TASEPs) on a twin co-axial square tracks. In this biologically motivated model the particles in each track act as mobile bottlenecks against the movement of the particles in the other although the particle are not allowed to move out of their respective tracks. So far as the outer track is concerned, the particles on the inner track act as bottlenecks only over a set of fixed segments of the outer track, in contrast to site-associated and particle-associated quenched randomness in the earlier models of disordered TASEP. In a special limiting situation the movement of particles in the outer track mimic a TASEP with a "point-like" immobile (i.e., quenched) defect where phase segregation of the particles is known to take place. The length of the inner track as well as the strength and number density of the mobile bottlenecks moving on it are the control parameters that determine the nature of spatio-temporal organization of particles on the outer track. Variation of these control parameters allow variation of the width of the phase-coexistence region on the flux-density plane of the outer track. Some of these phenomena are likely to survive even in the future extensions intended for studying traffic-like collective phenomena of polymerase motors on double-stranded DNA.

description: At the start of the PARSEC project the Data Strand wanted to get an ‘entry profile’: a picture of current data activity of the team members and their experience with tools along the data lifecycle. In the case of a synthesis group, where re-use of existing data is the standard, some of the traditional research life cycle steps are missed (e.g. Michener, 2012), a simplified data lifecycle being more relevant. In this project we wish to periodically review the status of • understanding and awareness of the wider data landscape, and • use of tools both across the whole group (synthesis and data strands), which will help us gauge group development. This will enable us, at an individual level to: (i) respond to needs, such as provide training opportunities, and (ii) most effectively capitalise on the skillsets in the group.

description: We examine the hypothesis that inflation is primarily driven by vacuum energy at a scale indicated by gauge coupling unification. Concretely, we consider a class of hybrid inflation models wherein the vacuum energy associated with a grand unified theory condensate provides the dominant energy during inflation, while a second "inflaton" scalar slow-rolls. We show that it is possible to obtain significant tensor-to-scalar ratios while fitting the observed spectral index.
