description: The study of intracluster light can help us to understand the mechanisms taking place in galaxy clusters, and to place constraints on the cluster formation history and physical properties. However, owing to the intrinsic faintness of ICL emission, most searches and detailed studies of ICL have been limited to redshifts z<0.4.We search for ICL in a subsample of ten clusters detected by the ESO Distant Cluster Survey (EDisCS), at redshifts 0.4

description: The United States, during both the Jimmy Carter and Ronald Reagan administrations, pursued humanitarian relief in the Horn of Africa and East Africa with an eye towards Cold War politics. During the Carter administration the focus was on Ethiopia and the regime of Mengistu Haile Mariam, while during the Reagan administration the United States’ efforts were mainly targeted towards Sudan and the regime of Gaffar Nimeiry. In both instances, the United States was concerned with the politics of the Cold War, trying to create a more positive image of the U.S. abroad by relieving world hunger, while also propping up governments that supported U.S. interests during the Cold War against the Soviet Union.
The Digital Foundation Platform -- A Multi-layered SOA Architecture for Intelligent Connected Vehicle Operating System

description: Legacy AD/ADAS development from OEMs centers around developing functions on ECUs using services provided by AUTOSAR Classic Platform (CP) to meet automotive-grade and mass-production requirements. The AUTOSAR CP couples hardware and software components statically and encounters challenges to provide sufficient capacities for the processing of high-level intelligent driving functions, whereas the new platform, AUTOSAR Adaptive Platform (AP) is designed to support dynamically communication and provide richer services and function abstractions for those resource-intensive (memory, CPU) applications. Yet for both platforms, application development and the supporting system software are still closely coupled together, and this makes application development and the enhancement less scalable and flexible, resulting in longer development cycles and slower time-to-market. This paper presents a multi-layered, service-oriented intelligent driving operating system foundation (we named it as Digital Foundation Platform) that provides abstractions for easier adoption of heterogeneous computing hardware. It features a multi-layer SOA software architecture with each layer providing adaptive service API at north-bound for application developers. The proposed Digital Foundation Platform (DFP) has significant advantages of decoupling hardware, operating system core, middle-ware, functional software and application software development. It provides SOA at multiple layers and enables application developers from OEMs, to customize and develop new applications or enhance existing applications with new features, either in autonomous domain or intelligent cockpit domain, with great agility, and less code through re-usability, and thus reduce the time-to-market.

description: We study the high-luminosity fixed-target neutrino experiments at MiniBooNE, MINOS and T2K and analyze their sensitivity to light stable states, focusing on MeV--GeV scale dark matter. Thermal relic dark matter scenarios in the sub-GeV mass range require the presence of light mediators, whose coupling to the Standard Model facilitates annihilation in the early universe and allows for the correct thermal relic abundance. The mediators in turn provide a production channel for dark matter at colliders or fixed targets, and as a consequence the neutrino beams generated at fixed targets may contain an additional beam of light dark matter. The signatures of this beam include elastic scattering off electrons or nucleons in the (near-)detector, which closely mimics the neutral current scattering of neutrinos. We determine the event rate at modern fixed target facilities and the ensuing sensitivity to sub-GeV dark matter.

description: The codes HiggsBounds and HiggsSignals compare model predictions of BSM models with extended scalar sectors to searches for additional scalars and to measurements of the detected Higgs boson at 125 GeV. We present a unification and extension of the functionalities provided by both codes into the new HiggsTools framework. The codes have been re-written in modern C++ with native Python and Mathematica interfaces for easy interactive use. We discuss the user interface for providing model predictions, now part of the new sub-library HiggsPredictions, which also provides access to many cross sections and branching ratios for reference models such as the SM. HiggsBounds now implements experimental limits purely through json data files, can better handle clusters of BSM particles of similar masses (even for complicated search topologies), and features an improved handling of mass uncertainties. Moreover, it now contains an extended list of Higgs-boson pair production searches and doubly-charged Higgs boson searches. In HiggsSignals, the treatment of different types of measurements has been unified, both in the $χ^2$ computation and in the data file format used to implement experimental results.

description: The properties of electrons in matter are of fundamental importance. They give rise to virtually all molecular and material properties and determine the physics at play in objects ranging from semiconductor devices to the interior of giant gas planets. Modeling and simulation of such diverse applications rely primarily on density functional theory (DFT), which has become the principal method for predicting the electronic structure of matter. While DFT calculations have proven to be very useful to the point of being recognized with a Nobel prize in 1998, their computational scaling limits them to small systems. We have developed a machine learning framework for predicting the electronic structure on any length scale. It shows up to three orders of magnitude speedup on systems where DFT is tractable and, more importantly, enables predictions on scales where DFT calculations are infeasible. Our work demonstrates how machine learning circumvents a long-standing computational bottleneck and advances science to frontiers intractable with any current solutions. This unprecedented modeling capability opens up an inexhaustible range of applications in astrophysics, novel materials discovery, and energy solutions for a sustainable future.

description: High-accuracy multicolor light curves of the binary system HD 189733, which contains an exoplanet, are analyzed. We have determined the radii of the star and the planet in the binary system, as well as the orbital inclination. The limb-darkening coefficients of the stellar disk were obtained in 10 filters in the wavelength interval 5500-10500 AA. The uncertainties of the fitted parameters were estimated using the differential-correction and confidence-area methods. The wavelength dependence of the limb-darkening coefficients is compared to the corresponding theoretical function for a model thin stellar atmosphere. We confirm the wavelength dependence of the exoplanet's radius found by Pont et al. The exoplanet radius increases with decreasing wavelength, which seems to argue for the presence of an atmosphere around the planet.

A bi-isotropic sphere is used as a simple example and its zero-backscattering conditions are studied. A theoretical model of an object composed of three orthogonal chiral particles made of conducting wire is presented as an analog of the zero-backscattering bi-isotropic sphere. A potential application of the object as a receiving antenna or a sensor with the ability to receive power from an arbitrary direction without backscattering is discussed.

The Wasserstein distance of order 1 for quantum spin systems on infinite lattices

description: We propose a generalization of the Wasserstein distance of order 1 to quantum spin systems on the lattice $\mathbb{Z}^d$, which we call specific quantum $W_1$ distance. The proposal is based on the $W_1$ distance for qudits of [De Palma et al., IEEE Trans. Inf. Theory 67, 6627 (2021)] and recovers Ornstein's $\bar{d}$-distance for the quantum states whose marginal states on any finite number of spins are diagonal in the canonical basis. We also propose a generalization of the Lipschitz constant to quantum interactions on $\mathbb{Z}^d$ and prove that such quantum Lipschitz constant and the specific quantum $W_1$ distance are mutually dual. We prove a new continuity bound for the von Neumann entropy for a finite set of quantum spins in terms of the quantum $W_1$ distance, and we apply it to prove a continuity bound for the specific von Neumann entropy in terms of the specific quantum $W_1$ distance for quantum spin systems on $\mathbb{Z}^d$. Finally, we prove that local quantum commuting interactions above a critical temperature satisfy a transportation-cost inequality, which implies the uniqueness of their Gibbs states.

Subhalo abundance matching using progenitor mass at varying redshift: Two modes of stellar mass growth imprinted into the Subaru HSC galaxy clustering

subject: FOS: Physical sciences

description: We propose a novel subhalo abundance matching (SHAM) model that uses the virial mass of the main progenitor of each (sub)halo $M_{\rm prog}$ as a proxy of the galaxy stellar mass $M_*$ at the time of observation. This $M_{\rm prog}$ model predicts the two-point correlation functions depending on the choice of the epoch $z_{\rm prog}$ at which $M_\mathrm{prog}$ is quoted. With $z_{\rm prog}$ as a fitting parameter, we apply the $M_{\rm prog}$ model to the angular correlation functions measured with varying stellar mass thresholds from $M_{*,~{\rm lim}}/(h^{-2}M_\odot)=10^{11}$ to $10^{8.6}$ using a sample of galaxies at $z\simeq0.4$ from the Subaru Hyper Suprime-Cam survey. The $M_{\rm prog}$ model can reproduce the observations very well over $10~h^{-1}{\rm kpc}\textrm{--}10~h^{-1}{\rm Mpc}$. We find that, for the samples of $10^{9.2}\leq M_{*,~{\rm lim}}/(h^{-2}M_\odot)\leq10^{10.2}$, the correlation functions predicted by the widely-used $V_{\rm peak}$ model lack amplitudes at $\lesssim1~h^{-1}{\rm Mpc}$, suggesting that $M_{\rm prog}$ is a better proxy of the galaxy stellar mass than conventional $V_{\rm peak}$. The $z_{\rm prog}$ parameter is highest ($z_{\rm prog}\simeq3$) for intermediate mass galaxies at $M_*\simeq10^{9.9}~h^{-2}M_\odot$, and becomes smaller down to $z_\mathrm{prog}\simeq1$ for both lower- and higher-mass galaxies. We interpret these trends as reflecting the downsizing in the in-situ star formation in lower-mass galaxies and the larger contribution of the ex-situ stellar mass growth in higher-mass galaxies.

A DSP based AC electronic load for unintentional islanding tests
Creators: name: Feng, Wei
Publisher: name: University of British Columbia
Year: 2009

description: The distributed generation (DG) system for the renewable energy resources is being used more and more widely around the world in the past decades. In order to protect the whole power system from the islanding situation, the interface inverters of the DG system have to pass the unintentional islanding test. In this study, a single phase AC electronic load is introduced to simulate the local loads under unintentional islanding conditions. This thesis proposes a proper schematic of the electronic loads based on the H-bridge dc-dc converter and analyzes the performance of this system with PowerSIM. Then, a set of specifications for different ranges of the electronic loads are calculated through theoretical formulas and the PSIM simulations. Meanwhile, the transfer function of the system is also derived to analyze the stability of the PI control system. According to the theoretical analysis and simulations, a control program is implemented based on the Texas Instruments (TI) Digital Signal Processor (DSP) TMS320F2407A for the different kinds of electronic loads. A test circuit is then built to validate the performance of the system. Some experiments are performed for the resitive, inductive and capacitive loads respectively.

description: Motivated by puzzling spin-glass behaviors observed in many pyrochlore-based magnets, effects of magnetoelastic coupling to local lattice distortions were recently studied by the authors for a bond-disordered antiferromagnet on a pyrochlore lattice [Phys. Rev. Lett. 107, 047204 (2011)]. Here, we extend the analyses with focusing on the critical property of the spin-glass transition which occurs concomitantly with a nematic transition. Finite-size scaling analyses are performed up to a larger system size with 8192 spins to estimate the transition temperature and critical exponents. The exponents are compared with those in the absence of the magnetoelastic coupling and with those for the canonical spin-glass systems. We also discuss the temperature dependence of the specific heat in comparison with that in canonical spin-glass systems as well as an experimental result.

description: The cultural process of gold mining is examined within the context of an area which has been subject to continuous gold mining for over a century, the Barkerville area of British Columbia. The physical background of this area and its position in the general history of gold mining are reviewed. The gold mining of the Barkerville area is considered under three time periods, delimited on the bas is of the predominant form of the mining technology employed. Thus the three periods are "the early period," "the hydraulic period," and "the lode mining period." The extent of mining, the form of its technology, the role of the government, t he organisation of the industry, and the effects of the mining on the landscape, are traced for each period. The landscape effects, under the headings of geomorphology, communications and settlements, and vegetation are mapped whenever possible. A comparative assessment of the effects of the various mining techniques is made: hydraulic mining producing the greatest landscape devastation. The recent introduction of a new land use, recreation, into the Barkerville area is considered in the light of its relationship to past gold mining. Current and possible future land use conflicts arising from this new development are indicated and recommendations made for handling them.

description: Participation in technologically-orientated recreational activities has been growing at an unprecedented rate. The number of snowmobiles, the subject of this study, has nearly doubled each year in the last decade. Attempts have been made to provide facilities in a variety of areas, including national parks where such use is inconsistent with general park policy. However, national park administrators, unaware of the characteristics and implications of oversnow vehicle operation, seem to have perceived an obligation to accormnodate the new sport within existing park facilities. Operation of oversnow vehicles in areas and on trails designed for other purposes creates numerous environmental and land-use conflicts. This thesis examines these problems in Banff National Park and Region. The findings of this thesis are based on a review of previous research, detailed trail transects, a photographic record of trail developments, and a mail-in questionnaire. The research reveals that snowmobile operation is: (1) a major cause of vegetation damage and erosion along designated trails; (2) a serious threat to subnivean creatures and other wildlife; and(3) an increasingly annoying management problem on public land. Each of the conflicts are substantially magnified if the trails are subsequently used by other off-the-road vehicles. In Banff National Park, the general land-use policies used to direct and control snowmobiling, have not been effectively applied. All of the trails currently designated for snowmobile use violate policy guidelines as well as the fundamental principles of the National Parks Act. The contradictory application of the policy provides the basis for recommending the withdrawal of oversnow vehicle operation in Banff National Park and similar preserves and rigidly controlling it in all other areas.
EUROMOD HHoT unemployment extensions. Technical report

description: Tax-benefit microsimulation models are typically used to quantify the effect of specific policy changes on the income distribution based on representative micro data. Such analysis evaluates policies by considering how different tax-benefit elements interact based on the personal, household and labour market characteristics of the underlying population. Hypothetical data takes the population structure out of the equation and focuses on model families with concrete specified personal, household and labour market characteristics. This helps to address broader questions of policy design and to compare systemic differences across countries. The focus of this work is the creation of hypothetical information that is usually not available in micro data. More concretely, I improved the simulation of unemployment policies when using hypothetical data by generating more detailed information on the prior work history in the hypothetical household tool HHoT. This information is taken into account through an extension in the EUROMOD tax-benefit microsimulation models.

description: Electron tomography offers important three-dimensional (3D) structural information which cannot be observed by two-dimensional imaging. By combining annular dark field scanning transmission electron microscopy (ADF-STEM) with aberration correction, the resolution of electron tomography has reached atomic resolution. However, tomography based on ADF-STEM inherently suffers from several issues, including a high electron dose requirement, poor contrast for light elements, and artifacts from image contrast nonlinearity. Here, we developed a new method called MultiSlice Electron Tomography (MSET) based on 4D-STEM tilt series. Our simulations show that multislice-based 3D reconstruction can effectively reduce undesirable reconstruction artifacts from the nonlinear contrast, allowing precise determination of atomic structures with improved sensitivity for low-Z elements, at considerably low electron dose conditions. We expect that the MSET method can be applied to a wide variety of materials, including radiation-sensitive samples and materials containing light elements whose 3D atomic structures have never been fully elucidated due to electron dose limitations or nonlinear imaging contrast.

description: We investigate the ground state properties of an ultracold atom system consisting of many-body polarons, quasiparticles formed by impurity atoms in optical lattices immersing in a Bose-Einstein condensate. We find the nearest-neighbor attractive interaction between polarons can give rise to rich physics that is peculiar to this system. In a relatively shallow optical lattice, the attractive interaction can drive the system being in a self-bound superfluid phase with its particle density distribution manifesting a self-concentrated structure. While in a relatively deep optical lattice, the attractive interaction can drive the system forming the Mott-insulator phase even though the global filling factor is not integer. Interestingly, in the Mott-insulator regime, the system can support a series of different Mott-insulators with their effective density manifesting a devil's staircase structure with respect to the strength of attractive interaction. Detailed estimation on relevant experimental parameters shows that these rich physics can be readily observed in current experimental setups.
E-Granary, digital literacy, and the identities of Ugandan students

description: The e-Granary Digital Library, commonly described as “Internet in a box”, is an external hard drive designed for users in poorly resourced communities. “Storing the seeds of knowledge”, the digital library contains vast information resources and can be navigated without Internet connectivity. This qualitative case study, which was conducted from September to December 2008 at the Kyato Community Library in the Ganda District of Uganda, used data collected from questionnaires, observations and interviews to address the following research questions: (i) What are students’ investments in e-Granary and computer technology and how does the development of digital literacy impact student identity? (ii) To what extent do students’ e-Granary digital literacy practices illuminate communalism within African indigenous knowledge? The analysis of my findings is informed by theories of identity (Norton, 2000) as well as discussions of indigeneity in the African context (Kanu, 2006; Dei, 1994, 2002). To address the research questions, the researcher drew on data collected from a group of six secondary school students to identify common themes related to identity, imagined communities, and communalism. The study found that the students were highly invested in ICT and expanded their range of real and imagined identities in relation to their digital literacy practices as they evolved from tutees to information finders and peer tutors. It also found that their digital literacy illuminated practices of communalism in their social setting in terms of knowledge sharing and working together for the betterment of the community. However, the study revealed that challenges in introducing ICT to a rural Ugandan community remain in effect. These include limited and faulty equipment, limited solar power, and inadequate human resources to assist in training and development. The study concludes with a recommendation for more qualitative case studies that will further investigate the home and community digital literacy practices of students, including the usage of cell phones and CDs.

description: Given a Hamiltonian system on a fiber bundle, there is a Poisson covariant formulation of the Hamilton equations. When a Lie group G acts freely, properly, preserving the fibers of the bundle and the Hamiltonian density is G-invariant, we study the reduction of this formulation to obtain an analogue of Poisson-Poincaré reduction for field theories. This procedure is related to the Lagrange-Poincaré reduction for field theories via a Legendre transformation. Finally, an application to a model of a charged strand evolving in an electric field is given.

description: The main object of this dissertation is to study the endomorphism algebra of a vector space with a family of invariant subspaces. Chapter 1 contains basic definitions and results which are used in the subsequent chapters. In particular, it includes a fairly detailed account of tensor products of modules and torsion free abelian groups of rank one. Chapter 2 is devoted to the discussion of the endomorphism algebra of a finite dimensional vector space with a finite set of invariant subspaces which satisfy certain distributivity conditions. Among other results we have established original theorems (2.1) and (2.3). Chapter 3 contains· the discussion of Brenner's five-space theorem (see [4]). Finally in Chapter 4, Brenner and Butler's theorem (see [5]), which proves the existence of a certain class of torsion free abelian groups, is established.

description: The impact of particle-vibration coupling and polarization effects due to deformation and time-odd mean fields on single-particle spectra is studied systematically in doubly magic nuclei from low mass $^{56}$Ni up to superheavy ones. Particle-vibration coupling is treated fully self-consistently within the framework of relativistic particle-vibration coupling model. Polarization effects due to deformation and time-odd mean field induced by odd particle are computed within covariant density functional theory. It has been found that among these contributions the coupling to vibrations makes a major impact on the single-particle structure. The impact of particle-vibration coupling and polarization effects on calculated single-particle spectra, the size of the shell gaps, the spin-orbit splittings and the energy splittings in pseudospin doublets is discussed in detail; these physical observables are compared with experiment. Particle-vibration coupling has to be taken into account when model calculations are compared with experiment since this coupling is responsible for observed fragmentation of experimental levels; experimental spectroscopic factors are reasonably well described in model calculations.

description: A theoretical model of the coherent precession of magnetization excited by a picosecond acoustic pulse in a ferromagnetic semiconductor layer of (Ga,Mn)As is developed. The short strain pulse injected into the ferromagnetic layer modifies the magnetocrystalline anisotropy resulting in a tilt of the equilibrium orientation of magnetization and subsequent magnetization precession. We derive a quantitative model of this effect using the Landau-Lifshitz equation for the magnetization that is precessing in the time-dependent effective magnetic field. After developing the general formalism, we then provide a numerical analysis for a certain structure and two typical experimental geometries in which an external magnetic field is applied either along the hard or the easy magnetization axis. As a result we identify three main factors, which determine the precession amplitude: the magnetocrystalline anisotropy of the ferromagnetic layer, its thickness, and the strain pulse parameters.

description: In the first billion years after the Big Bang, sources of ultraviolet (UV) photons are believed to have ionized intergalactic hydrogen, rendering the Universe transparent to UV radiation. Galaxies brighter than the characteristic luminosity $L^{*}$ do not provide enough ionizing photons to drive this cosmic reionization. Fainter galaxies are thought to dominate the photon budget; however they are surrounded by neutral gas that prevents the escape of the Lyman-$α$ photons, which has been the dominant way to identify them so far. JD1 was previously identified as a triply-imaged galaxy with a magnification factor of 13 provided by the foreground cluster Abell 2744, and a photometric redshift of $z\sim10$. Here we report the spectroscopic confirmation of this very low luminosity ($\sim0.05 L^{*}$) galaxy at $z=9.79$, observed 480 Myr after the Big Bang, by means of the identification of the Lyman break and redward continuum, as well as multiple $\gtrsim4σ$ emission lines, with the Near-InfraRed Spectrograph (NIRSpec) and Near-InfraRed Camera (NIRCam) instruments. The combination of the James Webb Space Telescope (JWST) and gravitational lensing shows that this ultra-faint galaxy ($M_{\rm UV}=-17.35$) -- with a luminosity typical of the sources responsible for cosmic reionization -- has a compact ($\sim$150 pc) and complex morphology, low stellar mass (10$^{7.19}$ M$_\odot$), and subsolar ($\sim$0.6 $Z_{\odot}$) gas-phase metallicity.
