description: The magnetic field of complete spin polarization is calculated in a disorderless single-valley strongly-interacting 2D electron system. In the metallic region above the Wigner-Mott transition, non-equilibrium spin states are predicted, which should give rise to hysteresis in the magnetization.
A Standard Law for the Equatorward Drift of the Sunspot Zones

description: The latitudinal location of the sunspot zones in each hemisphere is determined by calculating the centroid position of sunspot areas for each solar rotation from May 1874 to June 2011. When these centroid positions are plotted and analyzed as functions of time from each sunspot cycle maximum there appears to be systematic differences in the positions and equatorward drift rates as a function of sunspot cycle amplitude. If, instead, these centroid positions are plotted and analyzed as functions of time from each sunspot cycle minimum then most of the differences in the positions and equatorward drift rates disappear. The differences that remain disappear entirely if curve fitting is used to determine the starting times (which vary by as much as 8 months from the times of minima). The sunspot zone latitudes and equatorward drift measured relative to this starting time follow a standard path for all cycles with no dependence upon cycle strength or hemispheric dominance. Although Cycle 23 was peculiar in its length and the strength of the polar fields it produced, it too shows no significant variation from this standard. This standard law, and the lack of variation with sunspot cycle characteristics, is consistent with Dynamo Wave mechanisms but not consistent with current Flux Transport Dynamo models for the equatorward drift of the sunspot zones.

description: We develop statistical methods for identifying star streams in the halo of the Milky Way galaxy that exploit observed spatial and radial velocity distributions. Within a great circle, departures of the observed spatial distribution from random provide a measure of the likelihood of a potential star stream. Comparisons between the radial velocity distribution within a great circle and the radial velocity distribution of the entire sample also measure the statistical significance of potential streams. The radial velocities enable construction of a more powerful joint statistical test for identifying star streams in the Milky Way halo. Applying our method to halo stars in the Hypervelocity Star (HVS) survey, we detect the Sagittarius stream at high significance. Great circle counts and comparisons with theoretical models suggest that the Sagittarius stream comprises 10% to 17% of the halo stars in the HVS sample. The population of blue stragglers and blue horizontal branch stars varies along the stream and is a potential probe of the distribution of stellar populations in the Sagittarius dwarf galaxy prior to disruption.

So do the model parameters $c_α$, $α$ and $c_{4}$. Moreover, we show that the Weyl coupling parameter $γ$ and the model parameters $c_α$, $α$, $c_{4}$ which together control the size and strength of the conductivity coherence peak and the ratio of gap frequency over critical temperature $ω_{g}/T_{c}$.

description: Precision studies of top quark properties are currently underway at the LHC and Tevatron colliders with the prospect of probing anomalous t-W -b interactions. In the mean time, recent experimental results for the B_{d,s} - \bar{B}_{d,s} oscillation observables, the branching ratio B_s->μ^+μ^-, as well as the forward - backward asymmetry in B->K\starl^+l^-, accompanied by the accurate theoretical predictions for the relevant observables obtained within the SM motivate a combined study of these observables in the presence of anomalous t - W - b vertices. We investigate contributions of such anomalous couplings to the B->X_s l^+l^- decay mode, and combining them with the modifications of the B_{d,s} - \bar{B}_d,s, B->X_sγ observables, we determine indirect bounds on the real and imaginary parts of the anomalous t - W - b interactions. We find these to be mostly superior to present direct constraints coming from top decay and production measurements at the LHC and Tevatron. Finally, we predict the allowed effects in the branching ratios of the B_s->μ^+μ^- and B->K^{(*)}ν\barν, as well as the forward-backward asymmetry in B->K^*l^+l^-. We find that improved knowledge of these observables in the future could further constrain some of the anomalous tWb interactions.

description: In 1999, the Centre Street Bridge in Calgary was rehabilitated. The City of Calgary took the initiative to use the opportunity to test the performance of glass fibre reinforced polymer (GFRP) as a reinforcement material instead of steel rebar. GFRP was incorporated into a single span with the other spans still conventionally reinforced. This allowed a comparison between the performance of the GFRP reinforcing and standard steel rebar. An extensive monitoring programme was developed to provide the needed comparisons and monitor whether any problems developed with the GFRP. The objectives of the research described in this thesis were to conduct the comparison of the GFRP reinforcing to the steel, to conduct a comparison of sensor types and a monitoring system prototype whilst evaluating their potential as structural health monitoring and damage detection tools and finally to conduct an assessment of various structural health monitoring methods, and the needs and criteria necessary for health monitoring programmes. The project involved establishing an extensive sensing system on the Centre Street Bridge, gathering and analysing continuous data from the bridge and conducting controlled tests on the bridge. A model bridge was built in the structures laboratory of Dalhousie University and tested in various states of damage to help with the assessment of modal-based damage detection techniques that may be applicable to the Centre Street Bridge. Finite element models were constructed for both bridges to help with analysis and comparison of data. The results of the Centre Street Bridge Project have proven that GFRP and steel are performing similarly and adequately. Damage detection and long term monitoring will not be possible for the Centre Street Bridge with the sensing system in place. Sensors used on the bridge are neither very reliable nor protected adequately for durability. Damage detection techniques require more investigation and careful design. Structural health monitoring programmes require in-depth consideration before implementation and must account for both technical and non-technical issues.

description: We derive the relativistic kinetic equation for Compton scattering of polarized radiation in strong magnetic field using the Bogolyubov method. The induced scattering and the Pauli exclusion principle are taken into account. The electron polarization is also considered in the general form of the kinetic equation. The special forms of the equation for the cases of the non-polarized electrons, the rarefied electron gas and the two polarization mode description of radiation are found. The derived equations are valid for any photon and electron energies and the magnetic field strength below about 10^{16} G. These equations provide the basis for formulation of the equation for polarized radiation transport in atmospheres and magnetospheres of strongly magnetized neutron stars.

Electromechanical Impedance-Based Structural Health Monitoring for Damage Detection in Steel Structures

Publisher: name: Zenodo
Year: 2022

description: In 2018, part of the Morandi bridge in Italy collapsed and 43 people were killed, only because of a defect that could have been detected.
 To prevent such failures, implementing a structural health monitoring technique that secures the safety of life, property, and environment, is of great importance. If an appropriate method is used for damage detection, the infrastructure’s operational cost will be reduced since a low-cost repair can be scheduled timely.
 The electromechanical impedance-based method is a technique that can detect very small damages, like fatigue cracks, in steel infrastructure. In this online and in-situ method, a small, low-cost, and lightweight piezoelectric transducer is surface-mounted on a host structure.
 Opposite to the available solutions including acoustic emission, guided wave, and fiber optic sensing, the EMI method has clear advantages for fatigue crack monitoring:
 - It is an active technique and thus allows permanent monitoring.
 - The required hardware is very affordable for industries.
 - Piezoelectric transducers exhibit very good durability and survivability against temperature cycling and environmental exposure.
 - It can be applied to complex structures, e.g., a heavy-lifting crane.
 - The PZT sensors can be installed remotely from the crack location.
 The electromechanical impedance-based method does not require any shutdown of infrastructures. Therefore, they can have improved efficiency.
 Under the support of the Industrial Research Fund (IOF) of UGent, a project is initiated to further develop the EMI method towards a robust technology or industrial application. First, the effects of environmental and operational factors on the performance of the EMI method will studied for the sake of a technological proof-of-concept. The second goal is to build up a (wireless) measurement node system. Eventually, the ambition is to open a new horizon in EMI applications by integrating decision-making strategies for integrity analysis and maintenance planning of infrastructures.

description: Folding a sheet of paper along a curve can lead to structures seen in decorative art and utilitarian packing boxes. Here we present a theory for the simplest such structure: an annular circular strip that is folded along a central circular curve to form a three-dimensional buckled structure driven by geometrical frustration. We quantify this shape in terms of the radius of the circle, the dihedral angle of the fold and the mechanical properties of the sheet of paper and the fold itself. When the sheet is isometrically deformed everywhere except along the fold itself, stiff folds result in creases with constant curvature and oscillatory torsion. However, relatively softer folds inherit the broken symmetry of the buckled shape with oscillatory curvature and torsion. Our asymptotic analysis of the isometrically deformed state is corroborated by numerical simulations which allow us to generalize our analysis to study multiply folded structures.

description: Inference for causal effects can benefit from the availability of an instrumental variable (IV) which, by definition, is associated with the given exposure, but not with the outcome of interest other than through a causal exposure effect. Estimation methods for instrumental variables are now well established for continuous outcomes, but much less so for dichotomous outcomes. In this article we review IV estimation of so-called conditional causal odds ratios which express the effect of an arbitrary exposure on a dichotomous outcome conditional on the exposure level, instrumental variable and measured covariates. In addition, we propose IV estimators of so-called marginal causal odds ratios which express the effect of an arbitrary exposure on a dichotomous outcome at the population level, and are therefore of greater public health relevance. We explore interconnections between the different estimators and support the results with extensive simulation studies and three applications.

description: We provide an overview of some biomedical technologies able to relieve everyday impairments in neurological patients. Two literature searches from 2009 to 2020 were conducted using PubMed, Embase, Cinahl and Scopus. The studies meeting the criteria for eligibility constituted 224 of the 6257 identified studies. The first literature search resulted in the identification of 53 different neurological impairments. The following impairments were selected as the most general: six motor (walking/gait abnormality, paralysis/paresis, hypertonia, dystonia, tremor and ataxia), three cognitive (memory, attention/concentration and executive dysfunction), two sensory (visual and hearing impairments) and three uncategorized impairments (communication impairments, sleep abnormalities and seizures/epilepsies). The second literature search resulted in the identification of 22 biomedical technologies able to compensate or rehabilitate the neurological impairments. This review identified some of the common neurological impairments across diseases and showed that technology can be beneficial for neurological patients by helping them with everyday living. The review also found that different aspects such as personal aspects of the intended users (e.g., impairments) and physical and environmental context of the task play an essential role in the usefulness of the technology.Implications for rehabilitationNeurological diseases are globally the leading cause of disability, whereby there is a great need for rehabilitation of neurological impairments.Assistive technology can compensate for permanent impairments or be used in rehabilitation as an alternative to usual therapy or an adjunct to increase overall therapy time.This study provides an overview of existing assistive technology and how patients with neurological impairments can benefit from technology.

description: This discussion piece examines the role that New Zealand played in the global media narrative about Covid-19 responses. The New Zealand Government’s response in general, and Prime Minister Jacinda Ardern’s leadership in particular, came to stand as an example of functional governance to a world experiencing the accelerating fragmentation of Western neo-liberal geo-political economy. The ‘spectacle of competence’ that has characterized Ardern’s leadership is bound up in a pre-existing set of political fault lines that the pandemic has served to amplify. New Zealand’s geo-political cultural position, and the competence (both spectacular and actual) that its leadership has come to represent reveal something of the fracture of political economy of the global North and West, not least because the construction of New Zealand as representing a successful ‘Western’ response is geographically, economically and culturally inaccurate. Contrasting the New Zealand government’s pandemic response to the failed responses of Western models of governance, this piece argues that Jacinda Ardern’s leadership is important, not because it represents an example of Western success but rather because it represents a departure from the deadly consequences of neo-liberal norms.

description: For any (n+1)-dimensional weight vector χ of positive integers, the weighted projective space P(χ) is a projective toric variety, and has orbifold singularities in every case other than CP^n. We study the algebraic topology of P(χ), paying particular attention to its localisation at individual primes p. We identify certain p-primary weight vectors π for which P(π) is homeomorphic to an iterated Thom space over S^2, and discuss how any P(χ) may be reconstructed from its p-primary factors. We express Kawasaki's computations of the integral cohomology ring H^*(P(χ);Z) in terms of iterated Thom isomorphisms, and recover Al Amrani's extension to complex K-theory. Our methods generalise to arbitrary complex oriented cohomology algebras E^*(P(χ)) and their dual homology coalgebras E_*(P(χ)), as we demonstrate for complex cobordism theory (the universal example). In particular, we describe a fundamental class in Ω^U_{2n}(P(χ)), which may be interpreted as a resolution of singularities.

description: The Ricci tensor (Ric) is fundamental to Einstein's geometric theory of gravitation. The 3-dimensional Ric of a spacelike surface vanishes at the moment of time symmetry for vacuum spacetimes. The 4-dimensional Ric is the Einstein tensor for such spacetimes. More recently the Ric was used by Hamilton to define a non-linear, diffusive Ricci flow (RF) that was fundamental to Perelman's proof of the Poincare conjecture. Analytic applications of RF can be found in many fields including general relativity and mathematics. Numerically it has been applied broadly to communication networks, medical physics, computer design and more. In this paper, we use Regge calculus (RC) to provide the first geometric discretization of the Ric. This result is fundamental for higher-dimensional generalizations of discrete RF. We construct this tensor on both the simplicial lattice and its dual and prove their equivalence. We show that the Ric is an edge-based weighted average of deficit divided by an edge-based weighted average of dual area -- an expression similar to the vertex-based weighted average of the scalar curvature reported recently. We use this Ric in a third and independent geometric derivation of the RC Einstein tensor in arbitrary dimension.

description: A new Particle-in-Cell (PIC) method, that conserves energy exactly, is presented. The particle equations of motion and the Maxwell's equations are differenced implicitly in time by the midpoint rule and solved concurrently by a Jacobian-free Newton Krylov (JFNK) solver. Several tests show that the finite grid instability is eliminated in energy conserving PIC simulations, and the method correctly describes the two-stream and Weibel instabilities, conserving exactly the total energy. The computational time of the energy conserving PIC method increases linearly with the number of particles, and it is rather insensitive to the number of grid points and time step. The kinetic enslavement technique can be effectively used to reduce the problem matrix size and the number of JFNK solver iterations.

description: This article considers the creation of an exhibition at the National Library of New Zealand. Specifically, this project was a collaborative endeavour between the School of Design at Victoria University of Wellington and the National Library, aimed at utilising new technologies and traditional archival research to bring forgotten and rarely accessed data back to life in a public exhibition. From the outset this project sought to combine the best of both new educational technologies (augmented reality) with tactile, physical materials (created using laser cutting and 3D printing) that the public could handle and use in a way that would break down the barriers between exhibition objects and resurrected archival data. The result was an interactive exhibition focused upon the emergence of Wellington as a city and the growth of its waterfront over the last century and a half. The design research project took place between November 2016 and February 2017 and resulted in a project exhibition open to the public running from May 2017 to February 2018. The principle supervisors were Leon Gurevitch and Tim Miller with a research team of three research assistants (Stefan Peacock, Alasdair Tarry and Louis ElwoodLeach).

description: One of the main milestones in the study of opto- and electro-mechanical systems is to certify entanglement between a mechanical resonator and an optical or microwave mode of a cavity field. In this work, we show how a suitable time-periodic modulation can help to achieve large degrees of entanglement, building upon the framework introduced in [Phys. Rev. Lett. 103, 213603 (2009)]. It is demonstrated that with suitable driving, the maximum degree of entanglement can be significantly enhanced, in a way exhibiting a non-trivial dependence on the specifics of the modulation. Such time-dependent driving might help experimentally achieving entangled mechanical systems also in situations when quantum correlations are otherwise suppressed by thermal noise.

Seismic imaging using matched filters for operator weighting

description: Given a particular statistical measure of signal to noise (S/N), the 'matched filter' is an ideal linear filter for maximizing the S/N ratio of a signal amongst random, white noise. A matched filter approach to event detection in prestack migration is proposed, where 'signal' is defined as a particular amplitude variation with offset (AVO) reflection coefficient surface, and all other AVO response surfaces are considered 'noise'. Matched filtering of the prestack data with the signal illuminates reflection events whose AVO response curve matches that of the signal; other reflection energy is suppressed. Matched filter imaging enhances the detection of Class 2 AVO events, and results in an overall S/N improvement over conventional P-SV wave prestack migration.

description: Stroke is the main cause of long-term disability and happens mostly in the older population. Stroke affected patients experience either of the cognitive, visual or motor losses and recovery requires time and patience as they have to do physical exercises every day and at times repetitively. There are various types of stroke rehabilitation exercises focussing on technological solutions that include therapies performed using games. Motion-based games are popular in encouraging participants to perform repetitive tasks without being getting bored. Therefore, in this study, we have explored studies that included the use of games for stroke rehabilitation to understand the design principles and characteristics of the games used for these purposes. A number of medical respositories were searched for relevant articles in a window of 2008-2018. 18 studies were chosen for the scoping review depending on the inclusion criteria, and design principles used in these studies are analysed and evaluated. We present main findings from our review concerning the attributes of existing games for stroke rehabilitation such as meaningful play, handling of failures, emphasising challenge, and the value of feedback. We conclude with a list of design recommendations that future serious game developers can consider while designing interfaces for stroke patients.Implications for RehabilitationThis review exhibits that the usage of gaming technologies is a very effective interactive mechanism for stroke based rehabilitation.Further our review also shows that serious games provide an avenue and opportunity for customized and highly contextualized gameplayOur review also suggests that effective features to incorporate into serious games for rehabilitation includes; facilitating challenge and recovery from errors.

description: Exponential families are a particular class of statistical manifolds which are particularly important in statistical inference, and which appear very frequently in statistics. For example, the set of normal distributions, with mean μ and deviation σ, form a 2-dimensional exponential family. In this paper, we show that the tangent bundle of an exponential family is naturally a Kahler manifold. This simple but crucial observation leads to the formalism of quantum mechanics in its geometrical form, i.e. based on the Kahler structure of the complex projective space, but generalizes also to more general Kahler manifolds, providing a natural geometric framework for the description of quantum systems. Many questions related to this "statistical Kahler geometry" are discussed, and a close connection with representation theory is observed. Examples of physical relevance are treated in details. For example, it is shown that the spin of a particle can be entirely understood by means of the usual binomial distribution. This paper centers on the mathematical foundations of quantum mechanics, and on the question of its potential generalization through its geometrical formulation.

description: Η εκτεταμένου φάσματος β-λακταμάσες (ESBL), είναι ένζυμα που έχουν την ικανότητα να αδρανοποιούν τα β-λακταμικά αντιβιοτικά και κωδικοποιούνται από γονίδια χρωμοσωμιακής ή πλασμιδιακής προέλευσης. Η παραγωγή τους, αποτελεί τον κύριο μηχανισμό αντοχής της οικογένειας των Εντεροβακτηριοειδών. Τα στελέχη E. coli και Klebsiella spp. που ανήκουν στην οικογένεια αυτή, αποτελούν συχνό αίτιο ουρολοιμώξεων με πολλά από αυτά να ενοχοποιούνται για την παραγωγή ESBL. Η συνεχής εμφάνιση λοιμώξεων από στελέχη που παράγουν ESBL προκαλεί έντονη ανησυχία στην Ιατρική κοινότητα, καθώς συμβάλλει στην εξάπλωση της αντιμικροβιακής αντοχής και περιορίζει τις θεραπευτικές επιλογές για την αντιμετώπισή της. Σκοπός λοιπόν της παρούσας διπλωματικής, είναι η ανίχνευση εκτεταμένου φάσματος β-λακταμασών (ESBL) σε στελέχη E. coli και Klebsiella από καλλιέργειες ούρων ασθενών της κοινότητας της Βορείου Ελλάδος.
description: Extended-spectrum b-lactamases (ESBLs), are enzymes that confer resistance to b-lactam antibiotics and genes of plasmid or chromosomal origin encode them. Their production is the main resistance mechanism of the Enterobacteriaceae family. Strains that belong to this family are a frequent cause of urinary tract infections, with many of them being blamed for ESBL production. The continuous emergence of infections by ESBL-producing strains is a cause of great concern in the medical community, as it contributes to the spread of antimicrobial resistance and the limitation of therapeutic options. Based on the above, we understand that continuous antimicrobial resistance surveillance is needed to reduce the spread of resistant strains. For this reason, in recent years the medical community has undertaken various surveillance studies to address the significant threat posed by antimicrobial resistance. So, the purpose of this dissertation is the detection of ESBL in E. coli and Klebsiella strains isolated from urine cultures of community patients of Northern Greece.

description: In this work, we introduce a novel class of adaptive Monte Carlo methods, called adaptive independent sticky MCMC algorithms, for efficient sampling from a generic target probability density function (pdf). The new class of algorithms employs adaptive non-parametric proposal densities which become closer and closer to the target as the number of iterations increases. The proposal pdf is built using interpolation procedures based on a set of support points which is constructed iteratively based on previously drawn samples. The algorithm's efficiency is ensured by a test that controls the evolution of the set of support points. This extra stage controls the computational cost and the convergence of the proposal density to the target. Each part of the novel family of algorithms is discussed and several examples are provided. Although the novel algorithms are presented for univariate target densities, we show that they can be easily extended to the multivariate context within a Gibbs-type sampler. The ergodicity is ensured and discussed. Exhaustive numerical examples illustrate the efficiency of sticky schemes, both as a stand-alone methods to sample from complicated one-dimensional pdfs and within Gibbs in order to draw from multi-dimensional target distributions.

description: This summary is a short overview of a roundtable discussion that took place at the Renaissance Society of America on the topic of the structure and organization of a Digital Humanities curriculum. I invited two representatives of European and two of US curricula, which were split up respectively into one for Digital Art History and one for general Digital Humanities: Leif Isaksen (Professor of Digital Humanities, Exeter), Peter Bell (Junior professor for Digital Humanities, with a focus on Digital Art History, Erlangen-Nürnberg), Hannah Jacobs (Digital Humanities Specialist in the Wired! Lab for Digital Art & Visual Culture, Duke University), and Ashley Sanders Garcia (Vice Chair of the Digital Humanities Program, UCLA). Both of the European cases are recent implementations of new curricula, whereas the US-American had established courses. While established studies do exist in Europe, as for example at the University of London, they are still quite rare.

description: Charm and beauty production are probed with the ALICE experiment at the LHC by studying the single lepton transverse momentum distribution (electrons at mid-rapidity, muons at large-rapidities) and D mesons reconstructed in their hadronic decays. The differential production cross sections in proton proton interactions show a good agreement with perturbative QCD calculations at both sqrt(s) = 2.76 and 7 TeV. The measurements in lead lead reactions at sqrt(s_{NN})= 2.76 TeV evidence a reduction (or suppression) of the production rate at intermediate and high pt in the most central collisions with respect to the rate in proton proton interactions.

description: In this work we present the results of the bulk magnetization measurements in a superconducting state of single crystals of Ba$_{0.65}$Na$_{0.35}$Fe$_2$As$_2$. The isothermal magnetic field ($H||c$ axis) dependent magnetization ($M$) loops exhibit a second peak (SP) or `fishtail effect', as well as remarkable flux jumps at low temperatures. The critical current density $J_c$ obtained from the $M(H)$ loops is rather high, of the order of 10$^6$ A/cm$^2$. The analysis of the temperature and field dependent $J_c$ implies that high $J_c$ is mainly due to collective (weak) pinning of vortices by dense microscopic point defects with some contribution from a strong pinning mechanism. Pronounced magnetic instabilities in terms of flux jumps depend strongly on temperature as well on the field sweep rate. The field for first flux jump as calculated from an adiabatic model, however, is much lower than the experimentally observed values, and this enhanced stability is attributed to a flux creep phenomenon. The analysis of field dependent magnetic relaxation data additionally supports a collective pinning model. The data further suggests that SP in M(H) is likely related to crossover in creep dynamics from elastic to plastic mechanism. We have constructed the vortex phase diagram on field-temperature plane.

description: Factorization of the incompressible Stokes operator linking pressure and velocity is revisited. The main purpose is to use the inverse of the Stokes operator with a large time step as a preconditioner for Newton and Arnoldi iterations applied to computation of steady three-dimensional flows and to study of their stability. It is shown that the Stokes operator can be inversed within an acceptable computational effort. This inverse includes fast direct inverses of several Helmholtz operators and iterative inverse of the pressure matrix. It is shown, additionally, that fast direct solvers can be attractive for the inverse of the Helmholtz and Laplace operators on fine grids and at large Reynolds numbers, as well as for other problems where convergence of iterative methods slows down. Implementation of the Stokes operator inverse to time-stepping-based formulation of the Newton and Arnoldi iterations is discussed.
