A weighted relative isoperimetric inequality in convex cones
Creators: name: Indrei, Emanuel
Publisher: name: arXiv
Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: A weighted relative isoperimetric inequality in convex cones is obtained via the Monge-Ampere equation. The method improves several inequalities in the literature, e.g. constants in a theorem of Cabre--Ros--Oton--Serra. Applications are given in the context of a generalization of the log-convex density conjecture due to Brakke and resolved by Chambers: in the case of $α-$homogeneous ($α>0$), concave densities, (mod translations) balls centered at the origin and intersected with the cone are proved to uniquely minimize the weighted perimeter with a weighted mass constraint. In particular, if the cone is taken to be $\{x_n>0\}$, reflecting the density, balls intersected with $\{x_n>0\}$ remain (mod translations) unique minimizers in the $\mathbb{R}^n$ analog in the case when the density vanishes on $\{x_n=0\}$.

description: In this paper, we explore the relativistic quantum motion of spin-zero scalar charge-free particles influenced by rainbow gravity's (RG's) in Bonnor-Melvin magnetic space-time, a four-dimensional solution featuring a positive cosmological constant. We solve the Klein-Gordon equation in this scenario by using two sets of rainbow function: (i) $f(χ)=\frac{1}{(1-β\,χ)}$,\,\, $h(χ)=1$ and (ii) $f(χ)=\frac{1}{(1-β\,χ)}=h(χ)$, where $0 < χ\left(=\frac{|E|}{E_p}\right) \leq 1$ with $E_p$ being the Planck's energy, $E$ is the particle's energy, and $β$ is the rainbow parameter. Furthermore, we study the relativistic quantum oscillator through the Klein-Gordon oscillator equation in the same Bonnor-Melvin magnetic space-time under RG effects. Employing the first pair of rainbow function, we obtain an approximate eigenvalue solution of the quantum oscillator fields. Notably, we demonstrate that the relativistic energy profile of scalar and oscillator particles are influenced by the topology of the geometry and the cosmological constant which is related with the magnetic field strength lies along the symmetry axis. Additionally, we see the impact of rainbow parameter on these approximate relativistic energy profiles in both quantum systems.

title: The development of ‘drama’ in YouTube discourse
Creators: name: Pihlaja, Stephen
Publisher: name: The Open University
Year: 2012

description: This thesis presents a systematic discourse analysis of sustained antagonistic debate—called 'drama'—on the video-sharing website, YouTube. Following a two-year observation of a YouTube community of practice discussing Christianity and atheism, 20 video 'pages' (including talk from videos and text comments) from a drama event were identified and transcribed, producing a 86,859 word corpus comprising 136 minutes of video talk and 1,738 comments. Using metaphor-led discourse analysis (Cameron & Maslen, 2010b) of the total corpus, metaphor vehicles were identified, coded, and grouped by semantic and narrative relationships to identify systematic use and trace the development of discourse activity. Close discourse analysis of a subset of the corpus was then employed to investigate membership categorisation (Housley & Fitzgerald, 2002), impoliteness (Culpeper, 2011), and positioning (Harré & van Langenhove, 1998), providing a systematic description of different factors contributing to the emergence of 'drama'. Analysis shows that 'drama' developed when negative views of one user's impolite words exposed the different expectations of other users about acceptable YouTube interaction. Hyperbolic, metaphorical language derived from the Bible and narratives about tragic historical events often exaggerated, escalated, and extended negative evaluations of others. Categories like 'Christian' were used dynamically to connect impolite words and actions of individuals to social groups, thereby also extending negative evaluations. With implications for understanding 'flaming' and transgression of social norms in web 2.0 environments, this thesis concludes that inflammatory language led to 'drama' because: (1) users had diverse expectations about social interaction and organisation, (2) users drew upon the Bible's moral authority to support opposing actions, and (3) the online platform's technical features afforded immediate reactions to non-present others. The 'drama' then developed when users' responses to one another created both additional topics for antagonistic debate and more disagreement about which words and actions were acceptable.

description: We have calculated the evolution of cosmic ray (CR) modified astrophysical shocks for a wide range of shock Mach numbers and shock speeds through numerical simulations of diffusive shock acceleration (DSA) in 1D quasi- parallel plane shocks. The simulations include thermal leakage injection of seed CRs, as well as pre-existing, upstream CR populations. Bohm-like diffusion is assumed. We model shocks similar to those expected around cosmic structure pancakes as well as other accretion shocks driven by flows with upstream gas temperatures in the range $T_0=10^4-10^{7.6}$K and shock Mach numbers spanning $M_s=2.4-133$. We show that CR modified shocks evolve to time-asymptotic states by the time injected particles are accelerated to moderately relativistic energies ($p/mc \gsim 1$), and that two shocks with the same Mach number, but with different shock speeds, evolve qualitatively similarly when the results are presented in terms of a characteristic diffusion length and diffusion time. For these models the time asymptotic value for the CR acceleration efficiency is controlled mainly by shock Mach number. The modeled high Mach number shocks all evolve towards efficiencies $\sim 50$%, regardless of the upstream CR pressure. On the other hand, the upstream CR pressure increases the overall CR energy in moderate strength shocks ($M_s \sim {\rm a few}$). (abridged)

description: We study the future prospects of the 21cm forest observations on the axion-like dark matter when the spontaneous breaking of the global Peccei-Quinn (PQ) symmetry occurs after the inflation. The large isocurvature perturbations of order unity sourced from axion-like particles can result in the enhancement of minihalo formation, and the subsequent hierarchical structure formation can affect the minihalo abundance whose masses can exceed ${\cal O}(10^4) M_{\odot}$ relevant for the 21cm forest observations. We show that the 21cm forest observations are capable of probing the axion-like particle mass in the range $10^{-18}\lesssim m_a \lesssim 10^{-12}$ eV for the temperature independent axion mass. For the temperature dependent axion mass, the zero temperature axion mass scale for which the 21cm forest measurements can be affected is extended further to as big as of order $10^{-6}$ eV.

description: Vacuum electrical breakdowns, also known as vacuum arcs, are a limiting factor in many devices that are based on application of high electric fields near their component surfaces. Understanding of processes that lead to breakdown events may help mitigating their appearance and suggest ways for improving operational efficiency of power-consuming devices. Stability of surface performance at a given value of the electric field is affected by the conditioning state, i.e. how long the surface was exposed to this field. Hence, optimization of the surface conditioning procedure can significantly speed up the preparatory steps for high-voltage applications. In this article, we use pulsed dc systems to optimize the surface conditioning procedure of copper electrodes, focusing on the effects of voltage recovery after breakdowns, variable repetition rates as well as long waiting times between pulsing runs. Despite the differences in the experimental scales, ranging from $10^{-4}$ s between pulses, up to pulsing breaks of $10^5$ s, the experiments show that the longer the idle time between the pulses, the more probable it is that the next pulse produces a breakdown. We also notice that secondary breakdowns, i.e. those which correlate with the previous ones, take place mainly during the voltage recovery stage. We link these events with deposition of residual atoms from vacuum on the electrode surfaces. Minimizing the number of pauses during the voltage recovery stage reduces power losses due to secondary breakdown events improving efficiency of the surface conditioning.

description: In this letter, we explore the bandstructure effects on the performance of ballistic silicon nanowire transistors (SNWTs). The energy dispersion relations for silicon nanowires are evaluated with an sp3d5s* tight binding model. Based on the calculated dispersion relations, the ballistic currents for both n-type and p-type SNWTs are evaluated by using a semi-numerical ballistic model. For large diameter nanowires, we find that the ballistic p-SNWT delivers half the ON-current of a ballistic n-SNWT. For small diameters, however, the ON-current of the p-type SNWT approaches that of its n-type counterpart. Finally, the carrier injection velocity for SNWTs is compared with those for planar metal-oxide-semiconductor field-effect transistors, clearly demonstrating the impact of quantum confinement on the performance limits of SNWTs.

title: An Investigation Into The Blogging Practices Of Academics And Researchers
Creators: name: Heap, Tania Patricia
Publisher: name: The Open University

description: This research project investigated the experiences of academics and researchers using blogs to support their practice. The three research questions were: to identify the academics' and researchers' motivations for beginning and maintaining a blog, the contribution of blogging to their learning in the profession, and the challenges experienced. The research questions were investigated using several methods. Five datasets were collected from 26 participants. A questionnaire was first administered to collect background information about the bloggers, and was analysed quantitatively. Then, an initial unstructured interview of one open-ended question was conducted by email. The unstructured interview was analysed using descriptive phenomenology. A follow-on semi-structured interview was conducted and analysed by applying thematic analysis. Blog content was collected in parallel: textual extracts were analysed using discourse analysis and visual extracts by applying thematic/saliency analysis. Results revealed varied reasons for beginning a blog. For example, the blog can be used as a repository of 'half-baked' ideas. Blogging contributed to the academics' and researchers' learning in the profession in multiple ways. Academic bloggers, for example, can quickly reach a wider audience compared to other forms of academic publishing. Among the challenges, there were concerns over managing confidential information in public, and intellectual property issues. Regarding the methodological contribution of the research, suggestions on strategies for mixing and matching different research methods for data collection and analysis have been provided. An empirically-grounded framework of blog use in academia and research has been derived based on research findings and scholarship models in the literature. The framework describes how characteristics of digital scholarship such as openness and sharing, are manifested through blogging. The framework can be used to guide academics and researchers who are interested in taking up blogging as a scholarly practice. Finally, empirically-grounded guidelines on using blogs in academia and research have been derived. The guidelines were evaluated by four practitioners. Future work includes recruiting more practitioners to evaluate the guidelines.

description: The D_s^+ pi^0 and D_s^{*+} gamma decays of the D_{s0}^+(2317) are studied by assigning it to various charmed strange scalar mesons. As a result, it is found that its assignment to an iso-triplet four-quark meson is favored by the severest experimental constraint on the ratio of the rates for these decays, while assigning it to an I=0 state (a four-quark or a conventional {c\bar{s}}) is inconsistent with this constraint.

description: We study the pentaquark $uudd\bar s$ with $J=3/2$ and I=1 ($Θ^{++}$) in the QCD sum rule approach. We derive the QCD sum rules for positive and negative parity states of the pentaquark. The QCD sum rule predicts that there exists $Θ^{++}$ with negative parity and its mass is $1.5\sim1.6$ GeV. The negative parity $Θ^{++}$ can be extremely narrow, since it lies much below the $ΔK$ threshold and the decay into $KN$ state is strongly suppressed due to the $D$-wave centrifugal barrier. Also, the possibility of the existence of the $Θ^{++}$ with positive parity is not excluded. Although it nearly degenerates with the negative parity state, it may be broader than the negative parity state.

description: Background Fluoridation of public water systems is known as a safe and effective strategy for preventing dental caries based on evidence from non-randomized studies. Yet 110 million Americans do not have access to a fluoridated public water system and many others do not drink tap water. This article describes the study protocol for the first randomized controlled trial (RCT) of fluoridated water that assesses its potential dental caries preventive efficacy when delivered in bottles. Methods waterBEST is a phase 2b proof-of-concept, randomized, quadruple-masked, placebo-controlled, parallel-group trial designed to estimate the potential efficacy of fluoridated versus non-fluoridated bottled water to prevent dental caries incidence in the first 4 years of life. Two hundred children living in eastern North Carolina, USA, and aged 2–6 months at screening are being allocated at random in a 1:1 ratio to receive fluoridated (0.7 mg/L F) or non-fluoridated bottled water sourced from two local public water systems. Throughout the 3.5-year intervention, study water is delivered monthly in 5-gallon bottles to each child’s home with instructions to use it whenever the child consumes water as a beverage or in food preparation. Parents are interviewed quarterly to monitor children’s water consumption and health. At annual visits, the presence of dental caries is evaluated with a dental screening examination. Clippings from fingernails and toenails are collected to quantify fluoride content as a biomarker of total fluoride intake. The primary endpoint is the number of primary tooth surfaces decayed, missing, or filled due to dental caries measured by the study dentist near the time of the child’s fourth birthday. Tooth decay is assessed at the threshold of macroscopic enamel loss. For the primary aim, a least-squares, generalized linear model will estimate efficacy and its one-tailed, upper 80% confidence limit. Discussion waterBEST is the first evaluation of a randomized intervention of fluoridated drinking water in bottles to prevent dental caries in the primary dentition. This innovative method of delivering fluoridated water has the potential to prevent early childhood caries in a large segment of the US population that currently does not benefit from fluoridated public water.Trial registration ClinicalTrials.gov NCT04893681.

description: We visualize the Fermi-Pasta-Ulam-Tsingou (FPUT) recurrence in a classical Heisenberg ferromagnetic (HF) spin chain by exploiting its gauge eq uivalence to the nonlinear Schrödinger equation (NLSE). We discuss two types of spatially periodic breather excitations in the spin chain, that are associated with: (I) Akhmediev breather, and (II) Galilean transformed Akhmediev breather. The recurrence in the former is exact in the sense that the initial and final states are identical. In the later, the spin chain undergoes an additional global rotation during the rec urrence process, which makes the initial and final states distinguishable. Both the complex solutions (I) and (II) nevertheless show a definit e phase shift during the recurrence process. A one-to-one correspondence between HF spin chain and the NLSE seems missing by virtue of the clo seness of the FPUT recurrence.

description: We show that the perturbation of the Su-Schrieffer-Heeger chain by a localized lossy defect leads to higher-order exceptional points (HOEP). Depending on the location of the defect, third- and fourth- order exceptional points (EP3 \& EP4) appear in the space of Hamiltonian parameters. On the one hand, they arise due to the non-Abelian braiding properties of exceptional lines (EL) in parameter space. Namely, the HOEPs lie at intersections of mutually non-commuting ELs. On the other hand, we show that such special intersections happen due to the fact that the delocalization of edge states, induced by the non-Hermitian defect, hybridizes them with defect states. These can then coalesce together into an EP3. When the defect lies at the midpoint of the chain, a special symmetry of the full spectrum can lead to an EP4. In this way, our model illustrates the emergence of interesting non-Abelian topological properties in the multiband structure of non-Hermitian perturbations of topological phases.

Creators: name: Iacovides, Ioanna
Publisher: name: The Open University
Year: 2012

description: This thesis investigates the relationships between motivation, engagement and informal learning, with respect to digital games and adult players. Following the reconceptualisation of motivation and engagement (as forms of micro and macro level involvement respectively) three linked studies were conducted. In the first study, 30 players were interviewed via email about their gaming experiences. The resulting set of learning categories and themes drew attention to learning on a game, skill and personal level, which arose from micro-level gameplay and macro-level interaction with wider communities and resources. The second investigation consisted of eight case studies that examined how involvement and learning come together in practice. Participants were observed in the lab during two gameplay sessions and kept gaming diaries over a three week period. A method for categorising game-play breakdowns and breakthroughs (relating to action, understanding and involvement) was developed in order to analyse several hours of gameplay footage. The previous categories and themes were also applied to the data. The findings suggested a relationship between macro-involvement and player identity, which was further investigated by a third survey study (with 232 respondents). The survey helped to establish a link between identity, involvement, and learning; the more strongly someone identifies as a gamer, the more likely they are to learn from their involvement in gaming practice. Four main contributions are presented: (1) an empirical account of how informal learning occurs as a result of micro and macro-involvement within a gaming context, (2) an in-depth understanding of how breakdowns and breakthroughs relate to each other during play, (3) a set of categories that represent the range of learning experienced by players, and (4) a consideration of the role player identity serves with respect to learning and involvement.

description: The rapid adoption of artificial intelligence (AI) and machine learning (ML) has generated growing interest in understanding their environmental impact and the challenges associated with designing environmentally friendly ML-enabled systems. While Green AI research, i.e., research that tries to minimize the energy footprint of AI, is receiving increasing attention, very few concrete guidelines are available on how ML-enabled systems can be designed to be more environmentally sustainable. In this paper, we provide a catalog of 30 green architectural tactics for ML-enabled systems to fill this gap. An architectural tactic is a high-level design technique to improve software quality, in our case environmental sustainability. We derived the tactics from the analysis of 51 peer-reviewed publications that primarily explore Green AI, and validated them using a focus group approach with three experts. The 30 tactics we identified are aimed to serve as an initial reference guide for further exploration into Green AI from a software engineering perspective, and assist in designing sustainable ML-enabled systems. To enhance transparency and facilitate their widespread use and extension, we make the tactics available online in easily consumable formats. Wide-spread adoption of these tactics has the potential to substantially reduce the societal impact of ML-enabled systems regarding their energy and carbon footprint.

The transition to parenthood and the effects of unfulfilled expectations
Creators: name: Nazarinia, Roudi
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to evaluate the effects of mother's unfulfilled childcare and household labour expectations on their marital quality across the transition to parenthood. While including the nature of the childbirth experience. Findings from the 61 first-time mothers who volunteered for this study have shown three patterns of marital change across the transition to parenthood. Mothers have shown negative change in marital quality, no change in marital quality and positive change in marital quality. Unfulfilled childcare and household labour expectations both have a negative effect on the change in mothers' marital quality but neither of these factors affects this change as greatly as mothers' reports of stress during their childbirth experience. The more stressful a mother perceived her childbirth experience the more likely she was to have shown negative change in her marital quality.

description: The muLan experiment at the Paul Scherrer Institute will measure the lifetime of the positive muon with a precision of 1 ppm, giving a value for the Fermi coupling constant G_F at the level of 0.5 ppm. Meanwhile, by measuring the observed lifetime of the negative muon in pure hydrogen, the muCap experiment will determine the rate of muon capture, giving the proton's pseudoscalar coupling g_p to 7%. This coupling can be calculated precisely from heavy baryon chiral perturbation theory and therefore permits a test of QCD's chiral symmetry.

title: Alienation and Educational Inclusion: a mixed methods study of teaching and learning with contemporary art in the Level 1 university curriculum
Creators: name: Perryman, Leigh-Anne
Publisher: name: The Open University
Year: 2011

description: UNESCO (2006b) proclaims that ‘Arts Education is a universal human right’. However, art educators have observed that Western visual arts education is still dominated by a culturally exclusive canon of artworks which some students find alienating and irrelevant. Calls to abandon the canon in the name of inclusion have been made by school arts educators and research in secondary schools has shown that including contemporary art in the curriculum can empower and engage learners. However, inclusive visual arts curriculum development in higher education is infrequently explored. This thesis is intended to address such imbalance. It reports the findings of a mixed methods study exploring the impact of adults’ affective and cognitive responses to art on their learning. A questionnaire and interviews were used to gather information about Open University undergraduates’ responses to contemporary and non-contemporary artworks and their experiences of studying a visual arts module featuring meta-cognitive scaffolding and guided reflection. Quantitative and qualitative analysis of the data indicated that while the Western canon has the power to exclude, replacing canonical works with contemporary art is not a ‘one size fits all’ solution to achieving educational inclusion. Rather, it appears there is an age and experience-related divide in adults’ affective and cognitive responses to art. Younger, and art-trained adults often relish studying provocative, emotionally potent and offensive contemporary artworks, especially works addressing topics they feel are personally relevant. In contrast, some older adults’ cynical preconceptions about contemporary art’s unworthiness for serious study, and preferences for visually pleasing, inoffensive artworks, can prevent productive engagement with contemporary art. However, the study findings suggest that meta-cognitive scaffolding can offer a structure within which students can reflect on and make sense of their responses to contemporary art, while also developing the skills to interpret works with unstable and controversial meanings.

description: A new transient regime in the relaxation towards absolute equilibrium of the conservative and time-reversible 3-D Euler equation with high-wavenumber spectral truncation is characterized. Large-scale dissipative effects, caused by the thermalized modes that spontaneously appear between a transition wavenumber and the maximum wavenumber, are calculated using fluctuation dissipation relations. The large-scale dynamics is found to be similar to that of high-Reynolds number Navier-Stokes equations and thus to obey (at least approximately) Kolmogorov scaling.

description: Quadratic discriminant analysis (QDA) is a widely used classification technique. Based on a training dataset, each class in the data is characterized by an estimate of its center and shape, which can then be used to assign unseen observations to one of the classes. The traditional QDA rule relies on the empirical mean and covariance matrix. Unfortunately, these estimators are sensitive to label and measurement noise which often impairs the model's predictive ability. Robust estimators of location and scatter are resistant to this type of contamination. However, they have a prohibitive computational cost for large scale industrial experiments. We present a novel QDA method based on a recent real-time robust algorithm. We additionally integrate an anomaly detection step to classify the most atypical observations into a separate class of outliers. Finally, we introduce the label bias plot, a graphical display to identify label and measurement noise in the training data. The performance of the proposed approach is illustrated in a simulation study with huge datasets, and on real datasets about diabetes and fruit.

description: Isolated horizon conditions specialized to spherical symmetry can be imposed directly at the quantum level. This answers several questions concerning horizon degrees of freedom, which are seen to be related to orientation, and its fluctuations at the kinematical as well as dynamical level. In particular, in the absence of scalar or fermionic matter the horizon area is an approximate quantum observable. Including different kinds of matter fields allows to probe several aspects of the Hamiltonian constraint of quantum geometry that are important in inhomogeneous situations.

description: We have experimentally demonstrated pumping of Cooper pairs in a single-island mesoscopic structure. The island was connected to leads through SQUID (Superconducting Quantum Interference Device) loops. Synchronized flux and voltage signals were applied whereby the Josephson energies of the SQUIDs and the gate charge were tuned adiabatically. From the current-voltage characteristics one can see that the pumped current increases in 1e steps which is due to quasiparticle poisoning on the measurement time scale, but we argue that the transport of charge is due to Cooper pairs.

title: Supporting Location Privacy Management through Feedback and Control
Creators: name: Jędrzejczyk, Łukasz
Publisher: name: The Open University

description: Participation in modern, socially-focused digital systems involves a large degree of privacy management, i.e. controlling who may access what information under what circumstances. Effective privacy management (control) requires that mobile systems’ users be able to make informed privacy decisions as their experience and knowledge of a system progresses. By informed, we mean users be aware of the actual information flow. Moreover, privacy preferences vary across the context and it is hard to define privacy policy that reflects the dynamic nature of our lives. This research explores the problem of supporting awareness of information flow and designing usable interfaces for maintaining privacy policies ad-hoc. We borrow from the world of Computer Supported Collaborative Work (CSCW) and propose to incorporate social translucence, a design approach that “supports coherent behaviour by making participants and their activities visible to one another”. We use the characteristics of social translucence, namely visibility, awareness and accountability in order to introduce social norms in spatially dispersed systems. Our research is driven by two questions: (1) how can artifacts from real world social interaction, such as responsibility, be embedded into mobile interaction; and (2) can systems be designed in which both privacy violations and the burden of privacy management is minimized. The contributions of our work are: (1) an implementation of Buddy Tracker, privacy-aware location-sharing application based on the social translucence; (2) the design and evaluation of the concept of real-time feedback as a means of incorporating social translucence in location-sharing scenarios; and finally (3) a novel interface for ad-hoc privacy management called Privacy-Shake. We explore the role of real-time feedback for privacy management in the context of Buddy Tracker. Informed by focus group discussions, interviews, surveys and two field trials of Buddy Tracker we found that when using a system that provided real-time feedback, people were more accountable for their actions and reduced the number of unreasonable location requests. From our observations we develop concrete design guidelines for incorporating real-time feedback into information sharing applications in a manner that ensures social acceptance of the technology.

description: To reduce the impact of communicable diseases like COVID-19, collective action is required and likely to be susceptible to normative influence as well as whether people are more or less collectively oriented. We extend the theory of normative social behavior (TNSB) to account for group orientation and predict the relationships between social norms and physical distancing behaviors. Using a rolling cross-sectional design during 17 weeks of the pandemic, a national sample of US residents from 20 states (N = 8,778) participated in the study. The findings show that perceived descriptive norms, injunctive norms, and group orientation are significantly associated with physical distancing. The descriptive norm-behavior relationship and injunctive norm-behavior relationship are moderated by group orientation and the other predicted moderators in the TNSB. The findings extend the TNSB and highlight the need to understand social norms and group orientation in formative research for health communication campaigns designed to promote prevention behaviors.

description: We report on the impact of nonlinear four-magnon scattering on magnon transport in microstructured Co25Fe75 waveguides with low magnetic damping. We determine the magnon propagation length with microfocused Brillouin light scattering over a broad range of excitation powers and detect a decrease of the attenuation length at high powers. This is consistent with the onset of nonlinear four-magnon scattering. Hence, it is critical to stay in the linear regime, when deriving damping parameters from the magnon propagation length. Otherwise, the intrinsic nonlinearity of magnetization dynamics may lead to a misinterpretation of magnon propagation lengths and, thus, to incorrect values of the magnetic damping of the system.
