Subjects: subject: Konferenzschrift

description: High-dimensional problems appear naturally in various scientific areas. Two primary examples are PDEs describing complex processes in computational chemistry and physics, and stochastic/ parameter-dependent PDEs arising in uncertainty quantification and optimal control. Other highly visible examples are big data analysis including regression and classification which typically encounters high-dimensional data as input and/or output. High dimensional problems cannot be solved by traditional numerical techniques, because of the so-called curse of dimensionality. Rather, they require the development of novel theoretical and computational approaches to make them tractable and to capture fine resolutions and relevant features. Paradoxically, increasing computational power may even serve to heighten this demand, since the wealth of new computational data itself becomes a major obstruction. Extracting essential information from complex structures and developing rigorous models to quantify the quality of information in a high dimensional setting constitute challenging tasks from both theoretical and numerical perspective. The last decade has seen the emergence of several new computational methodologies which address the obstacles to solving high dimensional problems. These include adaptive methods based on mesh refinement or sparsity, random forests, model reduction, compressed sensing, sparse grid and hyperbolic wavelet approximations, and various new tensor structures. Their common features are the nonlinearity of the solution method that prioritize variables and separate solution characteristics living on different scales. These methods have already drastically advanced the frontiers of computability for certain problem classes. This workshop proposed to deepen the understanding of the underlying mathematical concepts that drive this new evolution of computational methods and to promote the exchange of ideas emerging in various disciplines about how to treat multiscale and high-dimensional problems.

description: Starting from the requirement of distinguishability of two atoms by their positions, it is shown that photon recoil has a strong influence on finite-time disentanglement and in some cases prevents its appearance. At near-field inter atomic distances well localized atoms, with maximally one atom being initially excited, may suffer disentanglement at a single finite time or even at a series of equidistant finite times, depending on their mean inter atomic distance and their initial electronic preparation.

Efficient simulation of non-crossing fibers and chains in a hydrodynamic solvent
Creators: name: Padding, J. T.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: An efficient simulation method is presented for Brownian fiber suspensions, which includes both uncrossability of the fibers and hydrodynamic interactions between the fibers mediated by a mesoscopic solvent. To conserve hydrodynamics, collisions between the fibers are treated such that momentum and energy are conserved locally. The choice of simulation parameters is rationalised on the basis of dimensionless numbers expressing the relative strength of different physical processes. The method is applied to suspensions of semiflexible fibers with a contour length equal to the persistence length, and a mesh size to contour length ratio ranging from 0.055 to 0.32. For such fibers the effects of hydrodynamic interactions are observable, but relatively small. The non-crossing constraint, on the other hand, is very important and leads to hindered displacements of the fibers, with an effective tube diameter in agreement with recent theoretical predictions. The simulation technique opens the way to study the effect of viscous effects and hydrodynamic interactions in microrheology experiments where the response of an actively driven probe bead in a fiber suspension is measured.

description: In this note, we apply a special metric ansatz to simplify the equations of motion for gravitational systems. Then we construct charged brane solutions in $D=n+p+2$ dimensions which have spherical symmetry of $S^n$ and translational symmetry along $p$ directions. They are characterized by mass density, uniform tension and electric/magnetic charges, and nonsingular only for specific tension. In particular, we find the limits and the coordinate transformations which reduce the charged brane solutions to $M2$- and $M5$-branes. We also obtain the regularity condition for an electrically charged two-brane solution which has two tensions.

description: Quantum field theory (QFT) may be considered one of the most fundamental frameworks of theoretical physics. Quantum Electrodynamics (QED) is the part of QFT that describes the interaction between matter and light. Although it is one of the experimentally best tested theories, it yet faces many open mathematical questions and challenges. The mathematical rigorous framework of QED and the implications deriving from it is the topic of Workshop 1737 held at MFO from September 11 through 15, 2017, bringing together mathematicians and theoretical physicists to discuss topics such as high- and low-energy QED, external field QED, quantum optics, many-boson and many-fermion systems, transport properties in condensed matter.
Mini-Workshop: MASAs and Automorphisms of C*-Algebras

description: The main aim of this workshop was to study maximal abelian *-subalgebras of C*-algebras from various points of view. A chief motivation is the UCT problem, which asks whether all separable nuclear C*-algebras satisfy the universal coefficient theorem of Rosenberg and Schochet. The connection, in terms of existence of invariant Cartan MASAs for certain *-automorphisms of the Cuntz algebra, has been brought up only very recently; it opens up a line of new perspectives on pressing questions in the structure and classification theory of simple nuclear C*-algebras and their automorphism groups, which has made giant leaps forward in the past five years. Connections to other areas, in particular von Neumann algebras and coarse geometry, have been explored as well.

description: Charge Coupled Devices (CCDs) have been successfully used in several high energy physics experiments over the past two decades. Their high spatial resolution and thin sensitive layers make them an excellent tool for studying short-lived particles. The Linear Collider Flavour Identification (LCFI) Collaboration has been developing Column-Parallel CCDs for the vertex detector of a future Linear Collider which can be read out many times faster than standard CCDs. The most recent studies are of devices designed to reduce both the CCD's intergate capacitance and the clock voltages necessary to drive it. A comparative study of measured Charge Transfer Inefficiency values between our previous and new results for a range of operating temperatures is presented.

description: There are several flavors of positivity in Algebraic Geometry. They range from conditions that determine vanishing of cohomology, to intersection theoretic properties, and to convex geometry. They offer excellent invariants that have been shown to govern the classification and the parameterization programs in Algebraic Geometry, and are finer than the classical topological ones. This mini-workshop aims to facilitate research collaboration in the area, strengthening the relationship between various positivity notions, beyond the now classical case of divisors/line bundles.

description: A collisionless plasma is modeled by the Vlasov-Poisson system in one-dimension. A fixed background of positive charge, dependent only upon velocity, is assumed and the situation in which the mobile negative ions balance the positive charge as x tends to positive or negative infinity. Thus, the total positive charge and the total negative charge are infinite. In this paper, the charge density of the system is shown to be compactly supported. More importantly, both the electric field and the number density are determined explicitly for large values of x.

description: One of the biggest mysteries in the modern cosmology and galaxy formation is the hideout of the 'missing baryons'. The leading theory of galaxy formation predicts that a huge amount of baryons resides around galaxies extending out to their virial radii in the form of diffuse and hot gas of $10^6-10^7\,$K, which is also known as the major component of the circumgalactic medium (CGM). Studies by various groups via different techniques, however, have not reached a consensus on the role of CGM in accounting for the missing baryons, with the estimated contribution ranging from a minor fraction to enclosing the baryon budget of the galaxy. In this work we attempt to measure the mass of missing baryons in CGM with a novel method based on the gamma-ray observations of the extended halo of the Andromeda Galaxy. Since cosmic-ray particles that are generated inside the galaxy will eventually escape to the CGM, they will produce gamma-ray emission via the proton-proton collision with CGM. Different from some traditional measurements which are sensitive only to gas in certain specific temperature range, the hadronic gamma-ray flux is sensitive to baryonic gases in all phases and does not rely on the metallicity in the halo. Our result suggests that the total baryon mass contained within the virial radius is less than $(1.4-5)\times 10^{10}M_\odot$ according to the gamma-ray observation. It implies that the CGM of Andromeda Galaxy may not account for more than $30\%$ of the missing baryons, but the result is subject to uncertainties from the diffusion coefficient of the CRs in the halo as well as the stellar mass and dark matter halo mass of the galaxy. This method will become more constraining provided better understandings on these issues and more sensitive gamma-ray telescopes in the future.

Can immobile magnetic vortex nucleate a vortex-antivortex pair?

description: It is shown that under the action of rotating magnetic field an immobile vortex, contrary to a general belief, can nucleate a vortex-antivortex pair and switch its polarity. Two different kinds of OOMMF micromagnetic modeling are used: (i) the original vortex is pinned by the highly--anisotropic easy-axes impurity at the disk center, (ii) the vortex is pinned by artificially fixing the magnetization inside the vortex core in the planar vortex distribution. In both types of simulations a dip creation with a consequent vortex-antivortex pair nucleation is observed. Polarity switching occurs in the former case only. Our analytical approach is based on the transformation to the rotating frame of reference, both in the real space and in the magnetization space, and on the observation that the physical reason for the dip creation is softening of the dipole magnon mode due to magnetic field rotation.

Client characteristics of the Family Service Centres of Greater Vancouver

Publisher: name: University of British Columbia
Year: 2011

description: The Family Service Centres of Greater Vancouver Area is composed of a Main and branch offices. At this time, the Agency is asking whether the service delivery patterns in the Main and branch offices match the characteristics of their respective clients. As a result, this study was undertaken with the following general hypotheses: that there are significant differences between the Main Office, North Shore and Burnaby branches of the Family Service Centres of Greater Vancouver in the characteristics of those requesting service, the nature of their request and the type of approach to the Agency. A cross-sectional survey was made of all persons approaching the Main, Burnaby and North Shore offices during a four week period in October/November, 1967. A data schedule was used by intake personnel to secure information on the total of 411 approaches. Information regarding four variables was sought—socioeconomic status, family life stage, request for service, and type of approach. The Blishen Occupational Class Scale and the Duvall Family Life Stages were used as models. A computer was used in analysing the data. The findings revealed that there were some differences between the three offices in the four variables tested, and that the differences were most marked in socioeconomic class. The general hypothesis was therefore accepted. Further, it was found that generally, the clients came from the lower socioeconomic classes, and that they were child rearing families. Strikingly few aged persons approached the Agency for service. Information/referral was the most requested service in the total sample, and self-referral was found to be the most common type of approach. It is concluded that the Agency should consider varying the service delivery patterns to meet the unique constellation of needs of the clients approaching each office. There are implications also for a general evaluation of services in relation to client characteristics as well as for further research.

Caregivers’ engagement with online support
Creators: name: Barraclough, Johanna
Publisher: name: Lancaster University
Year: 2021

description: This thesis is comprised of a research paper, a literature review and a critical appraisal of the research process. The research paper investigates the use of a digital health intervention (DHI) by relatives of people with psychosis or bipolar disorder, with the aim of identifying the factors which impact their engagement. Individual interviews were conducted with participants, recruited through NHS Early Intervention in Psychosis services in the UK. An inductive thematic analysis resulted in three themes: (i) motivation to understand and be understood; (ii) personal relevance sustains engagement; and (iii) usability and interaction enhance engagement. The findings indicated that clinical support from a trusted source was critical to engagement. Participants also appreciated the opportunity to relate to relatives facing similar challenges in order to access support and learn new strategies. This implied that the development and implementation of DHIs should include input from caregivers to ensure content and delivery reflect the needs of the intended user. The literature review identified and synthesised the findings of 34 qualitative studies about how caregivers of people with physical or mental health conditions engaged with online peer support. Thematic synthesis resulted in two overarching themes which represent the function of online peer support for the participants: (i) meeting caregivers’ needs for a new type of sustaining friendship; and (ii) creating a space to express uncomfortable emotions. Caregivers’ engagement with flexible, emotionally supportive and reciprocal interaction online was underpinned by experiential similarity. Online peer support offered a safe space to express emotions away from the caregiving relationship and has potential to meet caregivers’ needs for support. The critical appraisal reflects on the findings of the research paper and the literature review, focussing on limitations; opportunities for future research; and the impact of reflexivity on the research process.

Double Au rows on Si(553) surface

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: A new structural model of Au induced Si(553) surface is proposed. The model accounts for recently experimentally found value of the Au coverage, i.e. 0.48 monolayer, which suggests formation of two gold chains on each Si(553) terrace. The resulting structural model, like the models of other vicinal Si surfaces, features the honey-comb chain, but there is no buckling at step edge, which is observed on Si(335)-Au and Si(557)-Au surfaces. The present model is more stable than the models with single Au chain only, and agrees very well with existing experimental data. In particular, calculated band structure, featuring two metallic bands coming from hybridization of the gold in both chains with neighboring Si atoms, perfectly matches the photoemission data. Moreover, theoretical scanning tunneling microscopy topography remains in excellent agreement with the experiment.

description: Principal component analysis (PCA) is a well-established research approach extensively utilised in the quantitative social sciences. The primary objective of the present study is to devise and evaluate a novel methodology that effectively addresses the mathematical and statistical treatment of spatio-temporal dependencies among multivariate datasets within PCA. This approach builds upon recent advancements in multifunctional PCA. The study aims to optimise the product of the variance of functional principal components and the Moran’s I index, thereby enhancing the analytical framework. Both simulation studies and a real example show that positive spatio-temporal principal components should be constructed using a distance-based spatial weight matrix, and negative ones using a border-length-based spatial weight matrix.

description: This deliverable describes the outcomes of the first 18 months of work on the NanoCommons Ontology, which builds on and expands the FP7-funded eNanoMapper ontology. With significantly fewer resources dedicated to ontologies than the eNanoMapper project had, the NanoCommons project has taken over the continued development of the eNanoMapper ontology, and the managed release of updated versions at regular intervals. NanoCommons has made two major releases of the ontology in a period of 18 months, based on needs from other NanoSafety Cluster projects and efforts, like Nanoreg2, Gracious, ACENano, the USA NIKC project, and the Malta Initiative.
 This deliverable introduces the history of the eNanoMapper ontology, how the NanoCommons project has taken over release management, the recent updates to the development of the ontology and updates to the content of the ontology. It also describes our efforts for continued dissemination of the ontology to support others in utilisation of the ontology to support interlinking of datasets from different projects and sources and the collaboration with other projects with specific ontology work packages or tasks to guarantee a harmonized approach. Significant work went into maintenance of the ontology, requiring updates in third-party ontologies, updating the hosting of the ontology, and exploration of current needs from other European, American and international projects, and the integration of an ontology mapping tool for integration of datasets into the NanoCommons Knowledgebase. This deliverable also summarizes new dissemination and networking activities, consisting of both physical meetings and online tutorials, and an outlook of the upcoming work resulting from gaps identified in the reported initial ontology, which includes the need to add definitions to many of the terms, and to adjust the organisation of some of the terms based on user feedback.

description: A "folklore conjecture, probably due to Tutte" (as described in [P.D. Seymour, Sums of circuits, Graph theory and related topics (Proc. Conf., Univ. Waterloo, 1977), pp. 341-355, Academic Press, 1979]) asserts that every bridgeless cubic graph can be embedded on a surface of its own genus in such a way that the face boundaries are cycles of the graph. In this paper we consider closed 2-cell embeddings of graphs and show that certain (cubic) graphs (of any fixed genus) have closed 2-cell embedding only in surfaces whose genus is very large (proportional to the order of these graphs), thus providing plethora of strong counterexamples to the above conjecture. The main result yielding such counterexamples may be of independent interest.
title: Curating Time, Contingency, Anachronism, Flirtation
Creators: name: Lopez Zambrano, Paula
Publisher: name: Goldsmiths, University of London
Year: 2021

description: This thesis is about curating and temporal paradoxes, resistances and perversions in relation to contingency, anachronism and flirtation. It is a theoretical and practical investigation, which considers the poetic and political potential of these three temporalities, incorporating them as mode of curatorial research. Contingency in institutional management processes, anachronism in curatorial narratives, flirtation in encounters in exhibitions, are regularly perceived as accidents to be evaded, outdated premises, or trivial and insignificant social behaviours. They are disregarded by dominant orders because they detach from control procedures, normativity and systems of power. Nevertheless, they remain in the domain of power even as their opposites. My project investigates the conceptual counter-power of these temporalities to intervene with time-scales and agendas that frame and define the concept of temporality in curating. It explores critical and creative strategies to suspend, anachronize and pervert material and symbolic orders inscribed in curatorial chronological apparatuses. The proposal is to re-create the suspended state of Being and not-Being of contingency, to reenact the ontological out-of-jointness of anachronism, to re-stage the oscillation of flirtatious encounters, thus to materialise places of encounter between theory, art, and people. It intends to transfer the discursive significations of these temporalities from avoided, reproved and diminished domains into intensified and embellished written and exhibited embodied metaphors of time. The intention is to flirt with the possibility of giving life to them for short moments, blinks or disjunctures of chronological time.

description: Topical phenomena in high-energy physics related to collision experiments of heavy nuclei ("Little Bang") and early universe cosmology ("Big Bang") involve far-from-equilibrium dynamics described by quantum field theory. One example concerns the role of plasma instabilities for the process of thermalization in heavy-ion collisions. The reheating of the early universe after inflation may exhibit rather similar phenomena following a tachyonic or parametric resonance instability. Certain universal aspects associated to nonthermal fixed points even quantitatively agree, and considering these phenomena from a common perspective can be fruitful.

description: Spatial GARCH models, like all other spatial econometric models, require the definition of a suitable weight matrix. This matrix implies a certain structure for spatial interactions. GARCH-type models are often applied to financial data because the conditional variance, which can be translated as financial risks, is easy to interpret. However, when it comes to instantaneous/spatial interactions, the proximity between observations has to be determined. Thus, we introduce an estimation procedure for spatial GARCH models under unknown locations employing the proximity in a covariate space. We use one-year stock returns of companies listed in the Dow Jones Global Titans 50 index as an empirical illustration. Financial stability is most relevant for determining similar firms concerning stock return volatility.
Ballistic-Ohmic quantum Hall plateau transition in graphene pn junction
Creators: name: Low, Tony

description: Recent quantum Hall experiments conducted on disordered graphene pn junction provide evidence that the junction resistance could be described by a simple Ohmic sum of the n and p mediums' resistances. However in the ballistic limit, theory predicts the existence of chirality-dependent quantum Hall plateaus in a pn junction. We show that two distinctively separate processes are required for this ballistic-Ohmic plateau transition, namely (i) hole/electron Landau states equilibration and (ii) valley iso-spin dilution of the incident Landau edge state. These conclusions are obtained by a simple scattering theory argument, and confirmed numerically by performing ensembles of quantum magneto-transport calculations on a 0.1um-wide disordered graphene pn junction within the tight-binding model. The former process is achieved by pn interface roughness, where a pn interface disorder with a root-mean-square roughness of 10nm was found to suffice under typical experimental conditions. The latter process is mediated by extrinsic edge roughness for an armchair edge ribbon and by intrinsic localized intervalley scattering centers at the edge of the pn interface for a zigzag ribbon. In light of these results, we also examine why higher Ohmic type plateaus are less likely to be observable in experiments.

The Importance of Binary Gravitational Microlensing Events Through High-Magnification Channel

description: We estimate the detection efficiency of binary gravitational lensing events through the channel of high-magnification events. From this estimation, we find that binaries in the separations ranges of 0.1 < s < 10, 0.2 < s < 5, and 0.3 < s < 3 can be detected with ~ 100% efficiency for events with magnifications higher than A=100, 50, and 10, respectively, where s represents the projected separation between the lens components normalized by the Einstein radius. We also find that the range of high efficiency covers nearly the whole mass-ratio range of stellar companions. Due to the high efficiency in wide ranges of parameter space, we point out that majority of binary-lens events will be detected through the high-magnification channel in lensing surveys that focus on high-magnification events for efficient detections of microlensing planets. In addition to the high efficiency, the simplicity of the efficiency estimation makes the sample of these binaries useful in the statistical studies of the distributions of binary companions as functions of mass ratio and separation. We also discuss other importance of these events.

description: The spatial Durbin model (SDM) is one of the most widely used models in spatial econometrics. It originated as a generalisation of the spatial error model (SEM) under a non-linear parametric restriction (see Anselin (1988, pp. 110–111)). This restriction should be tested to select an appropriate model between SDM and SEM. Perhaps, due to the complexity of executing a test for a non-linear hypothesis, this restriction is rarely tested in practice, though see Burridge (1981), Mur and Angulo (2006) and LeSage and Pace (2009, p. 164). This paper considers an alternative linear hypothesis to test the suitability of the SDM. To achieve this, we first use Rao’s score (RS) testing principle and then Bera and Yoon (1993)’s methodology to robustify the original RS tests. The robust tests that require only ordinary least squares (OLS) estimation are able to identify the specific source(s) of departure(s) from the baseline linear regression model. An extensive Monte Carlo study provides evidence that our suggested tests possess excellent finite sample properties, both in terms of size and power. Our empirical illustrations, with two real data sets, attest that the tests developed in this paper could be very useful in judging the suitability of the SDM for the spatial data in hand.
Assessing Socio-Economic Factors Influencing Household Vulnerability to Climate Change in Kaskazini (A) District, Zanzibar

description: Climate change is a time ticking bomb that for far too long humanity has paid lip-service to its redress. The reverberating consequences have been causing devastating losses, driving inequalities and exacerbating vulnerabilities calling for prudent interventions. Addressing vulnerability requires quality information and although there is extensive literature on vulnerability to climate change globally, information on what influences household vulnerability from the socio-economic paradigm in Zanzibar is dearthful. This study sought to fill this void by investigating the socio-economic factors that influence household vulnerability to the impacts of climate change in Kaskazini (A) district, Zanzibar. The research adopted a descriptive research methodology with quantitative methods to collect data from household heads. Collected data were augmented with data collated from a review of documentaries and case studies. Findings reveal that due to low education and poor access to information, perceptions on climate change, variability, and its causes are daunting. Additionally, a higher household population that is dependent on natural resources and climate-sensitive sectors indicated a higher sensitivity to the impacts of climate change. Moreover, a lack of ownership of physical assets compromise the local’s ability to secure loans and credit services to cushion themselves against climate-related shocks. In addition to low income, lack of safety nets and marginalization in decision-making characterize the island. This study recommends that investment in education, diversification of livelihoods as well as easing access to livelihood assets is necessary. To complement this, climate change information should be made accessible, in a timely and inclusive manner.

description: Nuclear stopping in the heavy ion collisions over a beam energy range from SIS, AGS up to SPS is studied in the framework of the modified UrQMD transport model, in which mean field potentials of both formed and "pre-formed" hadrons (from string fragmentation) and medium modified nucleon-nucleon elastic cross sections are considered. It is found that the nuclear stopping is influenced by both the stiffness of the equation of state and the medium modifications of nucleon-nucleon cross sections at SIS energies. At the high SPS energies, the two-bump structure is shown in the experimental rapidity distribution of free protons, which can be understood with the consideration of the "pre-formed" hadron potentials.
