description: The eigenvectors for graph $1$-Laplacian possess some sort of localization property: On one hand, any nodal domain of an eigenvector is again an eigenvector with the same eigenvalue; on the other hand, one can pack up an eigenvector for a new graph by several fundamental eigencomponents and modules with the same eigenvalue via few special techniques. The Courant nodal domain theorem for graphs is extended to graph $1$-Laplacian for strong nodal domains, but for weak nodal domains it is false. The notion of algebraic multiplicity is introduced in order to provide a more precise estimate of the number of independent eigenvectors. A positive answer is given to a question raised in [{\sl K.~C. Chang, Spectrum of the $1$-Laplacian and Cheeger constant on graphs, J. Graph Theor., DOI: 10.1002/jgt.21871}], to confirm that the critical values obtained by the minimax principle may not cover all eigenvalues of graph $1$-Laplacian.

Moving the goalposts: the transformation of television sport in the UK (1992-2014)
Creators: name: Milne, Michael
Publisher: name: University of Westminster
Year: 2014

description: Despite its prominence and popularity, television sport remains an underresearched area in media studies and is a subject that lacks a ready-made theoretical context. Consequently, a political economy approach - including ideas about value, commodification, transformations, power-relationships and the emergence of a profit-motivated sport-media-corporate axis – is used to answer 3 primary questions: 1) Whilst sports and broadcasting systems in the US and UK started from diametrically opposed positions post-World War II, why have the similarities between them, including a more overtly consumer-oriented approach in the UK, become the most noticeable features? 2) How do three often unseen upstream pre-production processes – technology, broadcasting rights and regulation - increasingly influence what television sport looks and sounds like, where it can be seen and who can see it? 3) How are upstream pre-production processes manifest downstream on the supply side in terms of (a) broadcasters (including who provides sports media) and (b) independent sports television production, including the day-to-day work of sports producers and directors? Two critical perspectives are added: 1) the central role of sports federations, ranging from the “peculiar economics of sport” (Neale, 1964) through to federation run host broadcast operations for major events; and, 2) a relevant micro-level analysis of downstream supply-side activities following the trickle down effect of significant upstream transformations. This new perspective complements the big picture often favoured by political economists. It is argued that important transformations in technology, broadcasting rights and regulation have radically changed the television sport landscape in the UK since 1992. How these factors have evolved goes a long way to explain (a) what sport we see on television, (b) where we can see it and (c) what the final output looks and sounds like. The battle to control broadcasting rights and subsequent television output is set against the increasing commercialisation of sport and the marketisation of broadcasting.

description: Messenger RNA (mRNA) therapeutics have recently demonstrated high clinical potential with the accelerated approval of SARS-CoV-2 vaccines. To fulfill the promise of unprecedented mRNA-based treatments, the development of safe and efficient carriers is still necessary to achieve effective delivery of mRNA. Herein, we prepared mRNA-loaded nanocarriers for enhanced in vivo delivery using biocompatible block copolymers having functional amino acid moieties for tunable interaction with mRNA. The block copolymers were based on flexible poly(ethylene glycol)-poly(glycerol) (PEG-PG) modified with glycine (Gly), leucine (Leu) or tyrosine (Tyr) via ester bonds to generate block catiomers. Moreover, the amino acids can be gradually detached from the block copolymers after ester bond hydrolyzation, avoiding cytotoxic effects. When mixed with mRNA, the block catiomers formed narrowly distributed polymeric micelles with high stability and enhanced delivery efficiency. Particularly, the micelles based on tyrosine-modified PEG-PG (PEG-PGTyr), which formed a polyion complex (PIC) and π–π stacking with mRNA, displayed excellent stability against polyanions and promoted mRNA integrity in serum. PEG-PGTyr-based micelles also increased the cellular uptake and the endosomal escape, promoting high protein expression both in vitro and in vivo. Furthermore, the PEG-PGTyr-based micelles significantly extended the half-life of the loaded mRNA after intravenous injection. Our results highlight the potential of PEG-PGTyr-based micelles as safe and effective carriers for mRNA, expediting the rational design of polymeric materials for enhanced mRNA delivery.

description: Measurement of $Z$ bosons produced in association with charm jets $(Zc)$ in proton-proton collisions in the forward region provides a direct probe of a potential non-perturbative (intrinsic) charm component in the proton wave function. We provide a detailed study of the potential to measure $Zc$ production at the LHCb experiment in Runs 2 and 3 of the LHC. The sensitivity to valence-like (sea-like) intrinsic charm is predicted to be $\langle x \rangle_{\rm IC} \gtrsim 0.3\%(1\%)$. The impact of intrinsic charm on Higgs production at the LHC, including $Hc$, is also discussed in detail.

The effect of scene content on image quality
Creators: name: Oh, Kyung
Publisher: name: University of Westminster
Year: 2014

description: Device-dependent metrics attempt to predict image quality from an ‘average signal’, usually embodied on test targets. Consequently, the metrics perform well on individual ‘average looking’ scenes and test targets, but provide lower correlation with subjective assessments when working with a variety of scenes with different than ‘average signal’ characteristics. This study considers the issues of scene dependency on image quality. This study aims to quantify the change in quality with scene contents, to research the problem of scene dependency in relation to devicedependent image quality metrics and to provide a solution to it. A novel subjective scaling method was developed in order to derive individual attribute scales, using the results from the overall image quality assessments. This was an analytical top-down approach, which does not require separate scaling of individual attributes and does not assume that the attribute is not independent from other attributes. From the measurements, interval scales were created and the effective scene dependency factor was calculated, for each attribute. Two device-dependent image quality metrics, the Effective Pictorial Information Capacity (EPIC) and the Perceived Information Capacity (PIC), were used to predict subjective image quality for a test set that varied in sharpness and noisiness. These metrics were found to be reliable predictors of image quality. However, they were not equally successful in predicting quality for different images with varying scene content. Objective scene classification was thus considered and employed in order to deal with the problem of scene dependency in device-dependent metrics. It used objective scene descriptors, which correlated with subjective criteria on scene susceptibility. This process resulted in the development of a fully automatic classification of scenes into ‘standard’ and ‘non-standard’ groups, and the result allows the calculation of calibrated metric values for each group. The classification and metric calibration performance was quite encouraging, not only because it improved mean image quality predictions from all scenes, but also because it catered for nonstandard scenes, which originally produced low correlations. The findings indicate that the proposed automatic scene classification method has great potential for tackling the problem of scene dependency, when modelling device-dependent image quality. In addition, possible further studies of objective scene classification are discussed.
title: Crows' nests on power poles : finding a solution
Creators: name: McIvor, Guillam E.

description: Crows (Corvus cornix and C. corone) nest on power-poles throughout northern Scotland causing interruptions to electricity that cost the electricity provider more than £250,000 annually. I aimed to establish what factors influence the nest site selection of crows in the islands of Orkney to help determine ways to reduce pole nesting by these birds. Crows preferred nest sites in trees that were coniferous, tall, mature, densely grouped, and far from occupied houses. However, when such trees were scarce, the number of occupied houses was high, and there were no cliffs within 1km, crows were more likely to nest on power-poles. I found that the fitting of a Firefly diverter at sites where nests were removed was ineffective at deterring rebuilding, but rebuilding was less likely to occur the later in the season that nests were removed. Nests in the middle phase of construction were the most likely to be rebuilt. Making an appropriate decision as to when to remove a crow nest, therefore, would seem more effective for deterring nest rebuilding than is the fitting of Firefly diverters. Nest removal also reduced the level of pole nesting both within years and between years. Furthermore, planned interruptions led to fewer customers losing power and to a twelve-fold reduction in the number of minutes that customers were without power, relative to unplanned power-cuts caused by nests. I also attempted to determine the efficacy of providing alternative nesting platforms and of insulating the live wires on transformer boxes, but I collected too few data to confirm if either of these might reduce the number of power-cuts caused by crows' nests. As both nest platforms and insulation remain in place, however, data collected from these sites in the future may allow confirmation (or not) as to their value.
Evaluation of changes in image appearance with changes in displayed image size

description: This research focused on the quantification of changes in image appearance when images are displayed at different image sizes on LCD devices. The final results provided in calibrated Just Noticeable Differences (JNDs) on relevant perceptual scales, allowing the prediction of sharpness and contrast appearance with changes in the displayed image size. A series of psychophysical experiments were conducted to enable appearance predictions. Firstly, a rank order experiment was carried out to identify the image attributes that were most affected by changes in displayed image size. Two digital cameras, exhibiting very different reproduction qualities, were employed to capture the same scenes, for the investigation of the effect of the original image quality on image appearance changes. A wide range of scenes with different scene properties was used as a test-set for the investigation of image appearance changes with scene type. The outcomes indicated that sharpness and contrast were the most important attributes for the majority of scene types and original image qualities. Appearance matching experiments were further conducted to quantify changes in perceived sharpness and contrast with respect to changes in the displayed image size. For the creation of sharpness matching stimuli, a set of frequency domain filters were designed to provide equal intervals in image quality, by taking into account the system’s Spatial Frequency Response (SFR) and the observation distance. For the creation of contrast matching stimuli, a series of spatial domain S-shaped filters were designed to provide equal intervals in image contrast, by gamma adjustments. Five displayed image sizes were investigated. Observers were always asked to match the appearance of the smaller version of each stimulus to its larger reference. Lastly, rating experiments were conducted to validate the derived JNDs in perceptual quality for both sharpness and contrast stimuli. Data obtained by these experiments finally converted into JND scales for each individual image attribute. Linear functions were fitted to the final data, which allowed the prediction of image appearance of images viewed at larger sizes than these investigated in this research.
Gravitation Due to Scalar Potentials and Black Holes

description: This paper argues that the universe possesses two scalar potentials similar to those proposed by E.T. Whittaker in which waveforms travel longitudinally. It is proposed that these scalar potentials form through black holes, creating normal transverse electromagnetic radiation as well as gravity. This opens up new avenues for understanding the universe and black holes while applying parsimonious explanations to dark matter theories. Charge is envisioned as a widespread mechanical intermediate in the form of the scalar potentials, thus implying that the universe is similar to an atom. A new speed limit is determined and the critical MOND acceleration is derived using the Rydberg constant.

Structure-function studies of the Parkinsonism-linked protein DJ-1
Creators: name: Puno, Marc
Publisher: name: University of Westminster
Year: 2014

description: DJ-1 is a multifunctional protein linked to familial Parkinson’s disease. DJ-1 has been suggested to exert its cytoprotective function, in part, by acting as a copper carrier that can sequester the reactive metal and/or provide the copper cofactor for the activation of the Cu-Zn superoxide dismutase (SOD1). Using absorption spectroscopy and mass spectrometry, we found that DJ-1 binds one Cu(I) ion per DJ-1 homodimer. The structure of Cu(I)-bound DJ-1 reveals a new biscysteinate metal binding motif formed by juxtaposed Cys-53 at the homodimer interface. We calculated a subfemtomolar dissociation constant (Kd = 6.41 x 10-16 M) for Cu(I) that supports the physiological intracellular retention of the metal. Cu(I)-bound DJ-1 was not capable of interacting and activating SOD1 in vitro. We posit that DJ-1 sequester copper to protect against metal-induced cytotoxicity. Our results illuminate the molecular basis on how disease-linked mutations that impairs homodimerisation could disrupt the metal binding site. In the second part of this dissertation, we sought to determine the impact of a Parkinsonism-linked A107P mutation on DJ-1 structure and glyoxalase activity. The A107P variant abrogates the ability of DJ-1 to protect against glyoxal-induced cytotoxicity and carboxymethyllysine protein modification. A crystal structure of DJ-1 C106S variant with glycerol and sulphate bound in the active site suggests that Ala-107 is critical for the stabilization of the transition state of the nucleophilic addition step. In our hands, the protein levels of DJ-1 A107P mutant in SH-SH5Y cells were ostensibly similar to the wild-type level but reduced levels were found in HEK 293E and MEF cells. Using CD and NMR spectroscopy, we found that the structural defect caused by the mutation extends beyond the active site. The A107P mutation resulted in a remarkable misfolding of the protein providing a basis for the reduced intracellular protein level and the abrogation of enzymatic activity.

description: We study the bifurcation diagram of the Rössler system. It displays the various dynamical regimes of the system (stable or chaotic) when a parameter is varied. We choose a diagram that exhibits coexisting attractors and banded chaos. We use the topological characterization method to study these attractors. Then, we details how the templates of these attractors are subtemplates of a unique template. Our main result is that only one template describe the topological structure of height attractors. This leads to a topological partition of the bifurcation diagram that gives the symbolic dynamic of all bifurcation diagram attractors with a unique template.

description: Background. Despite major efforts in research, practice, and policy, racial and ethnic disparities in health and healthcare persist in the United States. Interventions in collaboration with governmental public health may provide ways to address these persistent racial and ethnic health and healthcare disparities and improve health outcomes, but there has not been a comprehensive review of health equity interventions performed in collaboration with public health agencies. Methods. This scoping review includes intervention studies from Ovid MEDLINE, PsycINFO, and Academic Search Premier, published between 2017 and 2023. The search strategy used terminology focused on four concepts: race/ethnicity, equity, health departments, and epidemiologic studies. Results. This review indicated that health equity interventions involving public health agencies focused on the following categories: 1) access to care, 2) health behavior, 3) infectious disease testing, 4) preventing transmission, and 5) cancer screening. Critical strategies included in interventions for reaching racialized populations included using community settings, mobile clinics, social media/social networks, phone-based interventions, community-based workers, health education, active public health department involvement, and structural/policy change. Conclusions. This scoping review aims to provide an evidence map to inform public health agencies, researchers, and funding agencies on gaps in knowledge and priority areas for future research, and to identify existing health equity interventions that could be considered for implementation by public health leaders and policymakers.

The chamber assembly time has been reduced by a factor of seven to one working day and the sense wire positioning accuracy improved by a factor of two to better than ten microns. Two sMDT chambers have been installed in ATLAS in 2014 to improve the momentum resolution in the barrel part of the spectrometer. The construction of an additional twelve chambers covering the feet regions of the ATLAS detector has started. It will be followed by the replacement of the MDT chambers at the ends of the barrel inner layer by sMDTs improving the Performance at the high expected background rates and providing space for additional RPC trigger chambers.

description: We obtained high-speed photometry of the disintegrating planetesimals orbiting the white dwarf WD1145+017, spanning a period of four weeks. The light curves show a dramatic evolution of the system since the first observations obtained about seven months ago. Multiple transit events are detected in every light curve, which have varying durations(~3-12min) and depths (~10-60%). The time-averaged extinction is ~11%, much higher than at the time of the Kepler observations. The shortest-duration transits require that the occulting cloud of debris has a few times the size of the white dwarf, longer events are often resolved into the superposition of several individual transits. The transits evolve on time scales of days, both in shape and in depth, with most of them gradually appearing and disappearing over the course of the observing campaign. Several transits can be tracked across multiple nights, all of them recur on periods of ~4.49h, indicating multiple planetary debris fragments on nearly identical orbits. Identifying the specific origin of these bodies within this planetary system, and the evolution leading to their current orbits remains a challenging problem.

description: In line with social exchange theory, this case study explores how a previously indifferent and unsympathetic local community participates in the conservation of Touran National Park through community-based tourism. An in-depth analysis of local community members, local authorities, and NGOs revealed that due to changes in society's socio-cultural structure, the community’s awareness of conservation has significantly increased and resulted in active participation in natural and cultural heritage. The findings provide an alternative to social exchange theory, suggesting that benefits should generally outweigh human social interaction and behaviour calculus costs. Furthermore, rural youth and women have become much more prominent despite many public participation dilemmas and rigid government structures. Finally, theoretical and practical implications for future research are discussed.

description: The original Parrondo game, denoted as AB3, contains two independent games: A and B. The winning or losing of A and B game is defined by the change of one unit of capital. Game A is a losing game if played continuously, with winning probability $p=0.5-ε$, where $ε=0.003$. Game B is also losing and it has two coins: a good coin with winning probability $p_g=0.75-ε$ is used if the player`s capital is not divisible by $3$, otherwise a bad coin with winning probability $p_b=0.1-ε$ is used. Parrondo paradox refers to the situation that the mixture of A and B game in a sequence leads to winning in the long run. The paradox can be resolved using Markov chain analysis. We extend this setting of Parrondo game to involve players with one-step memory. The player can win by switching his choice of A or B game in a Parrondo game sequence. If the player knows the identity of the game he plays and the state of his capital, then the player can win maximally. On the other hand, if the player does not know the nature of the game, then he is playing a (C,D) game, where either (C=A, D=B), or (C=B,D=A). For player with one-step memory playing the AB3 game, he can achieve the highest expected gain with switching probability equal to $3/4$ in the (C,D) game sequence. This result has been found first numerically and then proven analytically. Generalization to AB mod($M$) Parrondo game for other integer $M$ has been made for the general domain of parameters $p_b

Post-9/11 US civil-military relations and control of military strategy during Operation Iraqi Freedom

description: Current understanding of the post-9/11 US civil-military power relationship is clouded by the existence of various competing propositions as to whether civilian policymakers, military leaders or a combination of both have had the greatest influence in determining military strategy in Iraq. Motivated by the empirical and theoretical deficiencies of the post-9/11 US civil-military relations literature, this thesis traces the evolution of the shifting power relationship between civilian policymakers and military leaders in the formulation and implementation of US military strategy during Operation Iraqi Freedom (OIF) and explores the circumstances within which different balances of civil-military power occur. Using the policymaking process as an analytical framework, OIF is deconstructed into a series of decision points from 2001 to 2008 and the relative balance of civil-military power is identified at each according to one of five variations: Civilian Dominance; Shared Dominance Civilian; Shared Dominance; Shared Dominance Military; or Military Dominance. Using both qualitative and quantitative research methods, the thesis tests and explores the importance of six independent variables in explaining variations in the relative balance of civil-military power: civil-military preference divergence; civilian assertiveness; military assertiveness; civilian unity; military unity; and information advantage. In presenting a comprehensive analysis of civil-military power relations throughout OIF, the thesis offers a more nuanced response to the question of who controls US military strategy and demonstrates which independent variables hold the greatest potential for explaining variations in the relative balance of civil-military power. Analysis of the relationships between the dependent and independent variables reveals associations of varying strengths, thereby both confirming and challenging a number of the assumptions contained within the existing literature. By rooting contemporary research in the broader study of US civil-military relations, the thesis provides empirical clarity to the post-9/11 period as well as offering theoretical insight into the civil-military relationship beyond the limits of OIF.

description: The spin Seebeck effect (SSE) refers to the generation of a spin current as a result of a temperature gradient in magnetic materials including insulators. The SSE is applicable to thermoelectric generation because the thermally generated spin current can be converted into a charge current via spin-orbit interaction in conductive materials adjacent to the magnets. The insulator-based SSE device exhibits unconventional characteristics potentially useful for thermoelectric applications, such as simple structure, device-design flexibility, and convenient scaling capability. In this article, we review recent studies on the SSE from the viewpoint of thermoelectric applications. Firstly, we introduce the thermoelectric generation process and measurement configuration of the SSE, followed by showing fundamental characteristics of the SSE device. Secondly, a theory of the thermoelectric conversion efficiency of the SSE device is presented, which clarifies the difference between the SSE and conventional thermoelectric effects and the efficiency limit of the SSE device. Finally, we show preliminary demonstrations of the SSE in various device structures for future thermoelectric applications and discuss prospects of the SSE-based thermoelectric technologies.

Social media: digital content creation and sharing. A study of adults
Creators: name: Riley, Tim
Publisher: name: University of Westminster

description: In the first few years of the 21st Century, access to and use of Web 2.0 digital technologies by everyday, non-professional web users increased considerably in the UK. Today anyone of any age with access to a computer, digital tools and an internet connection can engage in social media dialogues as creators and publishers of digital content. This practice is no longer the preserve of the professional. Many academics and media commentators see this as a significant shift from the way individuals traditionally receive and ‘passively’ consume media to a position where they are more actively, responsively and inclusively engaged. In the last fifteen years much research has been concerned with the online actives of children and young people. Several web commentators have written with enthusiasm of the ‘net generation’ and ‘digital natives’. However, little research has been conducted into the digital and online engagement of adult web users. This study investigates how adults aged 18-28, 40-50 and +65 create, publish and share content online. Content creation, in the context of this project, is defined as an arrangement of visual and/or audio material that requires some element of composition or editing. Through the use of qualitative interviews this research provides an insight into the practices of these three age ranges of adults who use digital technology and the internet to create and share their content. The study addresses how they use content sharing to communicate online and their motivations for engaging in these practices. Issues of this kind are of importance for individuals’ selfexpression and participation in an increasingly digitalised world. The research found that participants from all age groups often used both digital and analogue technologies side-by-side and this helped, rather than hindered, their ability to create and share content. Several participants, particularly the over-65s, revealed that digital technologies were enablers that unlocked suppressed behaviour and creative desires. Artistic self-expression, personal achievement, affiliation to others and receiving recognition and feedback were all given as motivational reasons for creating and sharing content across the age spectrum. The research findings offer an alternative to the over-simplistic and sometimes polemical perception that the so-called ‘digital generation’ are more digitally adept and literate than older internet users.

description: Multiplex networks are representations of multilayer interconnected complex networks where the nodes are the same at every layer. They turn out to be good abstractions of the intricate connectivity of multimodal transportation networks, among other types of complex systems. One of the most important critical phenomena arising in such networks is the emergence of congestion in transportation flows. Here we prove analytically that the structure of multiplex networks can induce congestion for flows that otherwise will be decongested if the individual layers were not interconnected. We provide explicit equations for the onset of congestion and approximations that allow to compute this onset from individual descriptors of the individual layers. The observed cooperative phenomenon reminds the Braess' paradox in which adding extra capacity to a network when the moving entities selfishly choose their route can in some cases reduce overall performance. Similarly, in the multiplex structure, the efficiency in transportation can unbalance the transportation loads resulting in unexpected congestion.

description: Topological solitons are relevant in several areas of physics [1]. Recently, these configurations have been investigated in contexts as diverse as hydrodynamics [2], Bose-Einstein condensates [3], ferromagnetism [4], knotted light [5] and non-abelian gauge theories [6]. In this paper we address the issue of wave propagation about a static Hopf soliton in the context of the Nicole model. Working within the geometrical optics limit we show that several nontrivial lensing effects emerge due to nonlinear interactions as long as the theory remains hyperbolic. We conclude that similar effects are very likely to occur in effective field theories characterized by a topological invariant such as the Skyrme model of pions.
