description: Phosphorene, the 2D material derived from black phosphorus, has recently attracted a lot of interest for its properties, suitable for applications in material science. In particular, the physical features and the prominent chemical reactivity on its surface render this nanolayered substrate particularly promising for electrical and optoelectronic applications. In addition, being a new potential ligand for metals, it opens the way for a new role of the inorganic chemistry in the 2D world, with special reference to the field of catalysis. The aim of this review is to summarize the state of the art in this subject and to present our most recent results in preparation, functionalization and use of phosphorene and its decorated derivatives. In particular, we discuss several key points, which are currently under investigation: the synthesis, the characterization by theoretical calculations, the high pressure behaviour of black phosphorus, as well as decoration with nanoparticles and encapsulation in polymers. Finally, device fabrication and electrical transport measurements are overviewed on the basis of recent literature and new results collected in our laboratories.

description: We construct two classes of exact solutions to the field equations of topologically massive electrodynamics coupled to topologically massive gravity in 2 + 1 dimensions. The self-dual stationary solutions of the first class are horizonless, asymptotic to the extreme BTZ black-hole metric, and regular for a suitable parameter domain. The diagonal solutions of the second class, which exist if the two Chern-Simons coupling constants exactly balance, include anisotropic cosmologies and static solutions with a pointlike horizon.

description: The financial crisis has set new challenges for European integration, including the revision of priorities, principles and mechanisms of micro-prudential supervision of financial markets. Amongst the significant institutional reforms, the intensification of controls on financial markets has been pursued through the establishment of the European Supervisory Authorities in the financial markets (ESAs). This Article aims to analyse the role that these Authorities have been playing in shaping the EU legal order after the financial crisis. As a result of the EMU-related regulation aimed at enhancing EU financial stability after the crisis, the ESAs institutionalise administrative cooperation in micro-prudential supervision. The combination of agencification and crisis management is not new to the development of European integration nor specific to the case of financial markets. Nevertheless, the ESAs represent a peculiar regulatory experience, which share many characteristics of EU agencies, yet move towards an embryonic model of independent regulators. Compared to other EU agencies, in fact, they enjoy wider powers and a much more autonomous status from the Commission. They have acquired highly relevant competences that enhance their role in the internal market regulation. In addition, the CJEU engaged in a partial revision of the interpretative boundaries of the Meroni doctrine concerning the non-delegation of regulatory powers on agencies, allowing the ESAs to exercise some substantive regulatory prerogatives. This Article investigates how these competences affect the EU model of legality, showing to what extent the delegation of powers has changed as a result of the crisis.

description: We show that the codifference is a useful tool in studying the ergodicity breaking and non-Gaussianity properties of stochastic time series. While the codifference is a measure of dependence that was previously studied mainly in the context of stable processes, we here extend its range of applicability to random-parameter and diffusing-diffusivity models which are important in contemporary physics, biology and financial engineering. We prove that the codifference detects forms of dependence and ergodicity breaking which are not visible from analysing the covariance and correlation functions. We also discuss a related measure of dispersion, which is a non-linear analogue of the mean squared displacement.

Britannia Mine hydrology
Creators: name: Zabil, David
name: Lawrence, Gregory A.
Publisher: name: The University of British Columbia
Year: 2009

description: For the purpose of treatment plant design, the hydrology of the Britannia Mine area was investigated. Precipitation data were collected from four precipitation gauges near the Britannia Mine and flow data were collected from the two major outflow points of the mine. The data were analyzed to determine the relationship between precipitation and flow rate. In addition, return period analysis was performed to determine the treatment plant design flow rate. The possibility of storing water inside the mine to attenuate the peak flows and decrease the treatment plant design flow rate was examined. The precipitation/outflow relationship indicated that a complex routing mechanism exists in the mine workings. Groundwater appeared to contribute a significant portion of the total flow rate. Flow peaks were delayed for up to one week before exiting the mine. Forty-two years of record were available to generate return period graphs for mine outflows and precipitation events. There was a strong relationship between the annual precipitation volumes and the annual mine outflow volumes over the period of record. Calculations indicated that the treatment plant design flow rate may be reduced to nearly half of the average annual maximum flow if the mine workings are used as a storage reservoir.

description: The advent of laser cooling and optical manipulation for atomic samples revolutionized atomic physics in 1990’s, allowing the creation of new phases of matter, more accurate atomic clocks, and enabling leading candidates for the first functional quantum computer. This could not have been predicted at the time, and is a testament to the value of fundamental research for its own sake. These same laser cooling techniques are now being applied to simple molecular systems with the same revolutionary potential. In this thesis, I will present a range of experiments exploring these schemes in a new class of molecules, the diatomic alkaline earth hydrides. We present the creation and characterization of a bright beam of cold barium hydride molecules, high precision spectroscopy of these samples, as well as optical deflection and transverse cooling. This represents the first laser cooling of a Hydride molecule. This is a crucial step towards the creation of new cold molecular samples for a variety of scientific applications. In the final chapter, I will change gears, and introduce new ideas for the detection of scalar field dark matter. While this variety of dark matter is typically searched for using atomic clocks, I will show that the same coupling also leads to anomalous acceleration of test masses. This acceleration would be detectable using both a network of precision acceleration sensors known as the IGETS network, and by the LIGO observatory. This new technique will compliment existing search strategies, and has higher sensitivity for a wide region of parameter space.

description: In dense clouds of the interstellar medium, dust grains are covered by ice mantles, dominated by H$_2$O. CO and CO$_2$ are common ice components observed in infrared spectra, while infrared inactive N$_2$ is expected to be present in the ice. Molecules in the ice can be dissociated, react or desorb by exposure to secondary ultraviolet photons. Thus, different physical scenarios lead to different ice mantle compositions. This work aims to understand the behaviour of $^{13}$CO : N$_2$ and $^{13}$CO$_2$ : N$_2$ ice mixtures submitted to ultraviolet radiation in the laboratory. Photochemical processes and photodesorption were studied for various ratios of the ice components. Experiments were carried out under ultra-high vacuum conditions at 12K. Ices were irradiated with a continuous emission ultraviolet lamp simulating the secondary ultraviolet in dense interstellar clouds. During the irradiation periods, fourier-transform infrared spectroscopy was used for monitoring changes in the ice, and quadrupole mass spectrometry for gas-phase molecules. In irradiated $^{13}$CO$_2$ : N$_2$ ice mixtures, $^{13}$CO, $^{13}$CO$_2$, $^{13}$CO$_3$, O$_2$, and O$_3$ photoproducts were detected in the infrared spectra. N$_2$ molecules also take part in the photochemistry, and N-bearing molecules were also detected: NO, NO$_2$, N$_2$O, and N$_2$O$_4$. Photodesorption rates and their dependence on the presence of N$_2$ were also studied. As it was previously reported, $^{13}$CO and $^{13}$CO$_2$ molecules can transfer photon energy to N$_2$ molecules. As a result, $^{13}$CO and $^{13}$CO$_2$ photodesorption rates decrease as the fraction of N$_2$ increases, while N$_2$ photodesorption is enhanced with respect to the low UV-absorbing pure N$_2$ ice.

description: Sussex Archaeological Collections, 140, 41-47
description: Visual inspection of the pipeline easement during construction of a wastewater pipeline north of Itford Farm revealed a number of cut features in the chalk bedrock. Excavation revealed one of the features to be an Early Saxon sunken-floored building (grubenhaus) of fifth- to sixth-century date, from which a small but interesting assemblage of pottery was recovered. A boundary ditch of probable Saxo-Norman date was also investigated. Further features proved to be natural solution hollows in the chalk. No other structures were observed within the easement, but the discovery indicates the longevity of settlement at Itford Farm, and provides an interesting, albeit small-scale, example of shifting settlement patterns within the Ouse Valley.

description: We carry out a systematic study of the thermal conductivity of four single-layer transition metal dichalcogenides, MX$_2$ (M = Mo, W; X = S, Se) from first-principles by solving the Boltzmann Transport Equation (BTE). We compare three different theoretical frameworks to solve the BTE beyond the Relaxation Time Approximation (RTA), using the same set of interatomic force constants computed within density functional theory (DFT), finding that the RTA severely underpredicts the thermal conductivity of MS$_2$ materials. Calculations of the different phonon scattering relaxation times of the main collision mechanisms and their corresponding mean free paths (MFP) allow evaluating the expected hydrodynamic behaviour in the heat transport of such monolayers. These calculations indicate that despite of their low thermal conductivity, the present TMDs can exhibit large hydrodynamic effects, being comparable to those of graphene, especially for WSe$_2$ at high temperatures.

description: We study equations over torsion-free groups in terms of their `t-shape' (the occurences of the variable t in the equation). A t-shape is good if any equation with that shape has a solution. It is an outstanding conjecture that all t-shapes are good. In [Klyachko's methods and the solution of equations over torsion-free groups, l'Enseign. Maths. 42 (1996) 49--74] we proved the conjecture for a large class of t-shapes called amenable. In [Tesselations of S^2 and equations over torsion-free groups, Proc. Edinburgh Maths. Soc. 38 (1995) 485--493] Clifford and Goldstein characterised a class of good t-shapes using a transformation on t-shapes called the Magnus derivative. In this note we introduce an inverse transformation called blowing up. Amenability can be defined using blowing up; moreover the connection with differentiation gives a useful characterisation and implies that the class of amenable t-shapes is strictly larger than the class considered by Clifford and Goldstein.

description: In the context of radio galaxy classification, most state-of-the-art neural network algorithms have been focused on single survey data. The question of whether these trained algorithms have cross-survey identification ability or can be adapted to develop classification networks for future surveys is still unclear. One possible solution to address this issue is transfer learning, which re-uses elements of existing machine learning models for different applications. Here we present radio galaxy classification based on a 13-layer Deep Convolutional Neural Network (DCNN) using transfer learning methods between different radio surveys. We find that our machine learning models trained from a random initialization achieve accuracies comparable to those found elsewhere in the literature. When using transfer learning methods, we find that inheriting model weights pre-trained on FIRST images can boost model performance when re-training on lower resolution NVSS data, but that inheriting pre-trained model weights from NVSS and re-training on FIRST data impairs the performance of the classifier. We consider the implication of these results in the context of future radio surveys planned for next-generation radio telescopes such as ASKAP, MeerKAT, and SKA1-MID.

description: Latent variable models play an important role in psychological and educational measurement, which attempt to uncover the underlying structure of responses to test items. This thesis focuses on the development of statistical learning methods based on latent variable models, with applications to psychological and educational assessments. In that connection, the following problems are considered.
      The first problem arises from a key assumption in latent variable modeling, namely the local independence assumption, which states that given an individual's latent variable (vector), his/her responses to items are independent. This assumption is likely violated in practice, as many other factors, such as the item wording and question order, may exert additional influence on the item responses. Any exploratory analysis that relies on this assumption may result in choosing too many nuisance latent factors that can neither be stably estimated nor reasonably interpreted. To address this issue, a family of models is proposed that relax the local independence assumption by combining the latent factor modeling and graphical modeling. Under this framework, the latent variables capture the across-the-board dependence among the item responses, while a second graphical structure characterizes the local dependence. In addition, the number of latent factors and the sparse graphical structure are both unknown and learned from data, based on a statistically solid and computationally efficient method.
      The second problem is to learn the relationship between items and latent variables, a structure that is central to multidimensional measurement. In psychological and educational assessments, this relationship is typically specified by experts when items are written and is incorporated into the model without further verification after data collection. Such a non-empirical approach may lead to model misspecification and substantial lack of model fit, resulting in erroneous interpretation of assessment results. Motivated by this, I consider to learn the item - latent variable relationship based on data. It is formulated as a latent variable selection problem, for which theoretical analysis and a computationally efficient algorithm are provided.

Dem ÖPNV ermöglichen autonom fahrende Fahrzeuge die Aufstellung eines größeren und für den Fahrgast flexibleren Angebotes sowie einen insgesamt deutlich effizienteren Betrieb. Mögliche Anwendungsszenarien erstrecken sich von autonom fahrenden Linienbussen im Stadtverkehr bis hin zu autonomen On-Demand-Kleinbussen im suburbanen Raum. Hierfür ist eine breitgefächerte Anforderungsdefinition an die automatisierten Fahrzeuge des zukünftigen ÖPNV unerlässlich. Auf Basis dessen ist eine Bewertung von möglichen Anwendungsszenarien und ein Bewerten der Herausforderungen, vor denen diese Fahrzeuge stehen, realisierbar. Aktuell stehen die automatisierten Fahrzeuge für einen Einsatz im ÖPNV noch unbewältigten Herausforderungen gegenüber. In vielen deutschen Städten laufen daher derzeit Testprojekte mit autonom fahrenden Kleinbussen, die erste Erfahrungen im Realbetrieb sammeln. Dabei besteht nicht nur ein Interesse aus fahrzeugtechnischer Sicht, sondern auch ein Interesse von Seiten der ÖPNV-Betreiber, die mit den autonomen Kleinbussen einen neuen, automatisierten ÖPNV einleiten möchten.

description: The development of permanent magnets containing less or no rare-earth elements is linked to profound knowledge of the coercivity mechanism. Prerequisites for a promising permanent magnet material are a high spontaneous magnetization and a sufficiently high magnetic anisotropy. In addition to the intrinsic magnetic properties the microstructure of the magnet plays a significant role in establishing coercivity. The influence of the microstructure on coercivity, remanence, and energy density product can be understood by {using} micromagnetic simulations. With advances in computer hardware and numerical methods, hysteresis curves of magnets can be computed quickly so that the simulations can readily provide guidance for the development of permanent magnets. The potential of rare-earth reduced and free permanent magnets is investigated using micromagnetic simulations. The results show excellent hard magnetic properties can be achieved in grain boundary engineered NdFeB, rare-earth magnets with a ThMn12 structure, Co-based nano-wires, and L10-FeNi provided that the magnet's microstructure is optimized.

description: Virtual (VR) and augmented reality (AR) can bring an added value during the demonstration of knowledge, as for example within an interactive research demo. Callouts are strings of text which are connected by a line to a specific feature of an object. These visual annotations can be used during such demos and can be placed in different kinds of media, such as illustrations, technical drawings, images and videos. Callouts are also used in virtual 3D environments to anchor textual information to a specific point in space. Therefore they can be a valuable tool for virtually demonstrating knowledge. The alignment of callouts in such information rich environments is an elemental factor within the view management of the VR scene. In this paper we propose a concept for interactive microlearning application for knowledge demonstration that uses callouts as a fundamental element. We distinguish three types of interactive callout-representations by their alignment relative to the user, for being static or dynamic in their position and orientation. Within an implementation of the different callout versions we show the feasibility and in a user study we indicate a user-preference towards static positioned callouts.

description: We discuss the geometry of the Marsden-Ratiu reduction theorem for a bihamiltonian manifold. We consider the case of the manifolds associated with the Gel'fand-Dickey theory, i.e., loop algebras over sl(n+1). We provide an explicit identification, tailored on the MR reduction, of the Adler-Gel'fand-Dickey brackets with the Poisson brackets on the MR-reduced bihamiltonian manifold N. Such an identification relies on a suitable immersion of the space of sections of the cotangent bundle of N into the algebra of pseudo differential operators connected to geometrical features of the theory of (classical) W_n algebras.

description: We describe in this article a new code for evolving axisymmetric isolated systems in general relativity. Such systems are described by asymptotically flat space-times which have the property that they admit a conformal extension. We are working directly in the extended `conformal' manifold and solve numerically Friedrich's conformal field equations, which state that Einstein's equations hold in the physical space-time. Because of the compactness of the conformal space-time the entire space-time can be calculated on a finite numerical grid. We describe in detail the numerical scheme, especially the treatment of the axisymmetry and the boundary.

description: Mobile Virtual Reality (VR) has advanced considerably in the last few years, driven by advances in smartphone technology. There are now a number of commercial offerings available, from smartphone powered headsets to standalone units with full positional tracking. Similarly best practices in VR have matured quickly, facilitating comfortable and immersive VR experiences. There remains however many optimisation challenges when working with these devices, as while the need to render at high frame rates is universal, the hardware is limited by both computational power and battery capacity. There is also often a requirement that apps run smoothly across a wide variety of headsets. In this paper, we describe lessons learned in rendering and optimising underwater environments for mobile VR, based on our experience developing the popular aquatic safari application 'Ocean Rift'. We start by analyzing essential best practices for mobile app development, before describing low-cost techniques for creating immersive underwater environments. While some techniques discussed are universal to modern mobile VR development, we also consider issues that are unique to underwater applications.

Lattice QCD Simulations towards Strong and Weak Coupling Limits

description: Lattice gauge theory is a special regularization of continuum gauge theories and the numerical simulation of lattice quantum chromodynamics (QCD) remains as the only first principle method to study non-perturbative QCD at low energy. The lattice spacing a, which serves as the ultraviolet cut off, plays a significant role in determining error on any lattice simulation results. Physical results come from extrapolating a series of simulations with different values for a to a=0. Reducing the size of these errors for non-zero a improves the extrapolation and minimizes the error. In the strong coupling limit the coarse lattice spacing pushes the analysis of the finite lattice spacing error to its limit. Section 4 measures two renormalized physical observables, the neutral kaon mixing parameter BK and the Delta I=3/2 K pi pi decay amplitude A2 on a lattice with coarse lattice spacing of a ~ 1GeV and explores the a^2 scaling properties at this scale. In the weak coupling limit the lattice simulations suffer from critical slowing down where for the Monte Carlo Markov evolution the cost of generating decorrelated samples increases significantly as the lattice spacing decreases, which makes reliable error analysis on the results expensive. Among the observables the topological charge of the configurations appears to have the longest integrated autocorrelation time. Based on a previous work where a diffusion model is proposed to describe the evolution of the topological charge, section 2 extends this model to lattices with dynamical fermions using a new numerical method that captures the behavior for different Fourier modes. Section 3 describes our effort to find a practical renormalization group transformation to transform lattice QCD between two different scales, whose knowledge could ultimately leads to a multi-scale evolution algorithm that solves the problem of critical slowing down. For a particular choice of action, we have found that doubling the lattice spacing of a fine lattice yields observables that agree at the few precent level with direct simulations on the coarser lattice. Section 5 aims at speeding up the lattice simulations in the weak coupling limit from the numerical method and hardware perspective. It proposes a preconditioner for solving the Dirac equation targeting the ensemble generation phase and details its implementation on currently the fastest supercomputer in the world.
Lax pair tensors and integrable spacetimes

description: The use of Lax pair tensors as a unifying framework for Killing tensors of arbitrary rank is discussed. Some properties of the tensorial Lax pair formulation are stated. A mechanical system with a well-known Lax representation -- the three-particle open Toda lattice -- is geometrized by a suitable canonical transformation. In this way the Toda lattice is realized as the geodesic system of a certain Riemannian geometry. By using different canonical transformations we obtain two inequivalent geometries which both represent the original system. Adding a timelike dimension gives four-dimensional spacetimes which admit two Killing vector fields and are completely integrable.

description: Latinx communities in the United States made up 18% of the total population, yet accounted for 33% of COVID-19 morbidity and mortality. This supported the study aim to increase Latinx COVID-19 knowledge and self-efficacy for performing COVID-19 risk reduction mitigation behaviors via dissemination of the new online e-health intervention of the “Our COVID-19 Knowledge Test.” The study recruited online a largely female Latinx adult sample (N=118) with 68.6% born in the U.S. that was well-educated, given a mean education level of a bachelor’s degree; and, a mean annual household income of $50,000 to $99,000. During the pandemic year of 2020, 46.5% of the survey participants experienced moderate to maximum/extreme cultural stress, and moderately high COVID-19 related stress—while 66.9% reported depression, 78.8% anxiety, and 45.2% trauma. Their high rates of COVID-19 depression and anxiety were more than double those rates reported across samples identified globally during the pandemic. They experienced significant declines in their self-rated mental health status and physical health status from pre-pandemic to during the pandemic, high social support, and closest to a good quality of life. Supporting the value of the new “Our COVID-19 Knowledge Test” as a brief online e-health intervention, paired t-tests showed statistically significant increases in self-ratings for both COVID-19 knowledge and self-efficacy for COVID-19 risk reduction behaviors after taking the True-False test. Participants endorsed the dissemination of the new True-False “Our COVID-19 Knowledge Test” with all True answers as a brief online e-health intervention they would recommend to others as a way to learn about COVID-19. Meanwhile, on this True-False test, the sample evidenced very high knowledge of COVID-19. The sample also had a high intention to vaccinate or already vaccinated at 87%. Findings from independent t-tests, Pearson correlations, and regression analyses collectively affirmed the critical importance of having both high knowledge and high self-efficacy for performing preventive behaviors for reducing the risk of COVID-19 transmission, implementing mitigation strategies, and reducing mortality. Implications and recommendations focused on the value of the genre of a True-False test, with all True answers, for disseminating evidence-based information, and countering misinformation during pandemics and public health crises. Finally, the short tools used in this study were recommended for application in future research and as screening tools.
