description: Der Bedarf an Mobilität von Menschen und Gütern in einer weltweit wachsenden Zahl von urbanen Ballungsräumen führt in der Fahrzeugsystemtechnik zu den beiden Megatrends Elektrifizierung des Antriebs und autonomes Fahren, deren Industrialisierung neue Systemkomponenten und Technologien verfügbar macht. Dieser Impuls motiviert die Grundidee eines elektromechanischen Fahrwerks für Megacity-Mobilität, um zukünftigen Anforderungen bezüglich Komfort, Manövrierbarkeit und modularer Antriebe zu erfüllen und darüber hinaus den tatsächlichen Transportleistungsvorteil eines Mehrwegeverkehrssystems durch ein hochintegriertes Schienenfahrwerk nutzbar zu machen. Dem integrierten Systementwurf, der Mechanik, Aktorik und Regelung gleichrangig auch für die Fahrwerk-Grundfunktionen nutzt und damit Raum für die neuen Funktionen schafft, geht eine Analyse der zukünftigen Fahrzeuganforderungen sowie heute bekannter Fahrwerklösungen voraus. Zur Bewertung des Fahrwerks mitsamt seines neuartigen Aktors, der Fahrantrieb und Aktivfederung vereint, wird ein detailliertes Gesamtfahrzeug-Simulationsmodell erstellt, das den Nachweis der Konzepteigenschaften in relevanten Fahrmanövern auf der Straße und der Schiene erbringt.

description: We study a synchronization mechanism, based on one-way coupling of all-or-nothing type, applied to coupled map lattices with several different local rules. By analyzing the metric and the topological distance between the two systems, we found two different regimes: a strong chaos phase in which the transition has a directed percolation character and a weak chaos phase in which the synchronization transition occurs abruptly. We are able to derive some analytical approximations for the location of the transition point and the critical properties of the system. We propose to use the characteristics of this transition as indicators of the spatial propagation of chaoticity.

Using Technology to Identify Seepage Flow Paths Through, Under and Around Tailings Impoundments
Creators: name: Blanchard, Ryan
name: Kennedy, Judson
Publisher: name: The University of British Columbia
Year: 2024

description: Tailings impoundments continue to undergo failures at an unacceptably high rate, including failures at operations owned by high profile mining companies, for example the Brumadinho Dam failure in Brazil. These failures are often the result of a combination of design, construction and operation actions that are controlled by humans and must be better coordinated and managed in the future. The consequence of failure can be the discharge of tailings, environmental damage and loss of life. Any additional technology and information that enables an owner of a tailings impoundment to be more certain of its condition, and thereby reduce the risk of failure is of tremendous value to tailings and mine water management. The Magnetometric Resistivity (MMR) method can provide valuable information, and it involves the injection of a low frequency electrical current in the ground between two electrodes generating a magnetic field that can be measured at the ground’s surface with sensitive magnetic sensors. The map of the magnetic field, measured at the frequency of the injected current, can be used in turn to determine the position of the electric current paths in the ground. When the electric current is channelled in conductive paths, the MMR method can be used to identify the location of these paths. Conductive current paths are then interpreted as preferential seepage flow paths. A case study from Recycle Tailings Pond (RTP) at a gold mine in Alaska, USA is also presented. This dam had known seepage problems at the downstream toe of the dam. One grout curtain along the upstream toe of the dam and three smaller curtains that ran parallel to one another near the south abutment were installed to mitigate the seepage. Unfortunately, the seepage issues continued after the grout curtains were installed. A MMR investigation was performed on the tailings dam and the results showed the exact location of a preferential seepage flow path that bypassed the toe grout curtain and flowed through the dam. The remainder of the dam was performing as designed. With this information the client was able to make additional repairs and mitigate the seepage issues.

description: Inertial Confinement Fusion is a promising option to provide massive, clean, and affordable energy for humanity in the future. The present status of research and development is hindered by hydrodynamic instabilities occurring at the intense compression of the target fuel by energetic laser beams. A recent proposal Csernai et al. (2018) combines advances in two fields: detonations in relativistic fluid dynamics and radiative energy deposition by plasmonic nano-shells. The initial compression of the target pellet can be eliminated or decreased, not to reach instabilities. A final and more energetic laser pulse can achieve rapid volume ignition, which should be as short as the penetration time of the light across the target. In the present study, we discuss a flat fuel target irradiated from both sides simultaneously. Here we propose an ignition energy with smaller compression, largely increased entropy and temperature increase, and instead of external indirect heating and huge energy loss, a maximized internal heating in the target with the help of recent advances in nano-technology. The reflectivity of the target can be made negligible, and the absorptivity can be increased by one or two orders of magnitude by plasmonic nano-shells embedded in the target fuel. Thus, higher ignition temperature and radiation dominated dynamics can be achieved. Here most of the interior will reach the ignition temperature simultaneously based on the results of relativistic fluid dynamics. This makes the development of any kind of instability impossible, which up to now prevented the complete ignition of the target.

description: Yang-Mills color fields evolve chaotically in an anisotropically expanding universe. The chaotic behaviour differs from that found in anisotropic Mixmaster universes. The universe isotropizes at late times, approaching the mean expansion rate of a radiation-dominated universe. However, small chaotic oscillations of the shear and color stresses continue indefinitely. An invariant, coordinate-independent characterisation of the chaos is provided by means of fractal basin boundaries.

Structural and functional studies on the regulation of pyruvate carboxylase by the bacterial second messenger cyclic-di-AMP

description: The primary focus of this dissertation is the metabolic enzyme pyruvate carboxylase (PC). The structure and function of this fascinating enzyme has been studies and characterized by many laboratories over many decades. This extensive background is reviewed in Chapter 1, with an overview of the biotin-dependent carboxylase family and a particular focus on PC.  In this dissertation, we primarily use X-ray crystallography to study PC at a structural level. This dissertation is divided into two overarching sections, with the first section (Chapters 2-5) focusing on the bacterial second messenger cyclic-di-AMP (c-di-AMP). This project was initiated by our collaborators in the laboratory of Josh Woodward at the University of Washington, who performed the first screen to identify c-di-AMP binding proteins in the bacterium Listeria monocytogenes. In Chapters 2 and 3, the regulation of PC by c-di-AMP in L. monocytogenes as well as the bacterium Lactococcus lactis is discussed. Crystal structures of the PC from each of these species in complex with cyclic-di-AMP reveal the binding site and give insights into the molecular mechanisms of this regulation. In Chapters 4 and 5, structural studies of other c-di-AMP binding proteins identified in the screen are discussed. The second section (Chapters 6) focuses on a second class of PC enzymes called the two-subunit PCs, which are found in a subset of Gram-negative bacteria. In Chapter 6, the first crystal structure of a two-subunit PC from the bacterium Methylobacillus flagellatus is determined. In collaboration with the Lars Dietrich laboratory at Columbia University, we investigate the physiological function of the two-subunit PC in the pathogen Pseudomonas aeruginosa. A theme which emerges from these studies is that PC is an incredibly diverse enzyme which has been adapted for the peculiar physiological needs of each organism it inhabits. Because PC is found throughout nature in every kingdom of life, further studies of its unique properties and role in each organism are sure to provide more surprising insights in the years to come.

description: The NRC-CISTI library had its beginnings in 1924, when a small resource collection was established to serve the scientific staff of the newly organized laboratories of the National Research Council of Canada. The pioneering chief librarian, Margaret Gill, was appointed in 1928. The first president, Dr. H.M. Tory made it clear from the outset, however, that he intended to create “a library that would serve scientific workers everywhere in Canada.” During her 30 years, Miss Gill built up one of the strongest collections of scientific journals in Canada. NRC and its library moved in 1932 to its new location on Sussex Drive.

Modeling transport and mean age of dense core vesicles in large axonal arbors

description: A model simulating transport of dense core vesicles (DCVs) in type II axonal terminals of Drosophila motoneurons has been developed. The morphology of type II terminals is characterized by the large number of en passant boutons. The lack of both scaled up DCV transport and scaled down DCV capture in boutons results in a less efficient supply of DCVs to distal boutons. Furthermore, the large number of boutons that DCVs pass as they move anterogradely, until they reach the most distal bouton, may lead to the capture of a majority of DCVs before they turn around in the most distal bouton to move in the retrograde direction. This may lead to a reduced retrograde flux of DCVs and a lack of DCV circulation in type II terminals. The developed model simulates DCV concentrations in boutons, DCV fluxes between the boutons, age density distributions of DCVs, and the mean age of DCVs in various boutons. Unlike published experimental observations, our model predicts DCV circulation in type II terminals after these terminals are filled to saturation. This disagreement is likely because experimentally observed terminals were not at steady-state, but rather were accumulating DCVs for later release. Our estimates show that the number of DCVs in the transiting state is much smaller than that in the resident state. DCVs traveling in the axon, rather than DCVs transiting in the terminal, may provide a reserve of DCVs for replenishing boutons after a release. The techniques for modeling transport of DCVs developed in our paper can be used to model the transport of other organelles in axons.

description: Searches for optical transients are usually performed with a cadence of days to weeks, optimised for supernova discovery. The optical fast transient sky is still largely unexplored, with only a few surveys to date having placed meaningful constraints on the detection of extragalactic transients evolving at sub-hour timescales. Here, we present the results of deep searches for dim, minute-timescale extragalactic fast transients using the Dark Energy Camera, a core facility of our all-wavelength and all-messenger Deeper, Wider, Faster programme. We used continuous 20s exposures to systematically probe timescales down to 1.17 minutes at magnitude limits $g > 23$ (AB), detecting hundreds of transient and variable sources. Nine candidates passed our strict criteria on duration and non-stellarity, all of which could be classified as flare stars based on deep multi-band imaging. Searches for fast radio burst and gamma-ray counterparts during simultaneous multi-facility observations yielded no counterparts to the optical transients. Also, no long-term variability was detected with pre-imaging and follow-up observations using the SkyMapper optical telescope. We place upper limits for minute-timescale fast optical transient rates for a range of depths and timescales. Finally, we demonstrate that optical $g$-band light curve behaviour alone cannot discriminate between confirmed extragalactic fast transients such as prompt GRB flashes and Galactic stellar flares.

description: Excerpts from the report Summary: In the past 10 years there has been a sharp upturn nationally in home use of nonfat dry milk, while total use of fresh milk has been relatively stable and consumption of evaporated milk has fallen off markedly. The patterns of milk purchases of 477 families in the Chicago metropolitan area were studied over a 3-year period. Milk purchases of families who used nonfat dry milk were compared with those of families who did not use it. The analyses showed that families who purchased nonfat dry milk increased their total milk product purchases more than families who did not use it. The study also indicated that purchases of nonfat dry milk resulted in increased total milk consumption with little effect on purchases of fresh milk. There was practically no substitution between nonfat dry milk and evaporated and filled milk in the home. Data on purchases of nonfat dry milk, fresh fluid milk, evaporated milk, and filled milk were also analyzed to ascertain relationships between consumption patterns and family characteristics such as income, race, and size of family.
$μ$-term as the origin of baryon and lepton number asymmetry

Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study a possibility of combining an origin of the $μ$-term and the baryon and lepton number asymmetry. If we assume that the $μ$-term is generated through a flat direction of a singlet scalar field, the coherent oscillation of this condensate around its potential minimum can store the global U(1) charge asymmetry. The decay of this condensate can distribute this asymmetry into the lepton and baryon number asymmetry as far as its decay occurs at an appropriate temperature. We examine the compatibility between this scenario and the small neutrino mass generation based on both the ordinary seesaw mechanism and the bilinear R-parity violating terms.

description: Lead Halide Perovskites (LHPs) have emerged as an outstanding optical material, chiefly as attractive options for studies of light emission, due to their high quantum efficiencies, broad wavelength tuneability via chemical substitution, and facile growth conditions. LHPs have also been increasingly considered as an ideal candidate for exploring applications of exciton-polariton condensation, with a recent explosion of research in this area. The physical properties of LHPs are distinct from traditional materials often used to study exciton-polaritons, leading to debates over photo-physical mechanisms of stimulated emission, and interpretation of experimental results. This thesis addresses these debates in two parts, discussing (1) how the relatively low exciton-binding energy and phonon-bottleneck effects often leads to exciton dissociation prior to the laser powers needed to observe stimulated emission, and (2) how the optical birefringence associated with bulk CsPbBr3 at cryogenic temperatures will produce novel optical potentials which amount to a synthetic spin-orbit coupling of exciton-polaritons within a perovskite microcavity. These conclusions are reached by a combination of static and time-resolved spectroscopies, along with polarization-resolved Fourier-imaging optical techniques.

description: A quantum collision model (CM), also known as repeated interactions model, can be built from the standard microscopic framework where a system S is coupled to a white-noise bosonic bath under the rotating wave approximation, which typically results in Markovian dynamics. Here, we discuss how to generalize the CM construction to the case of frequency-dependent system-bath coupling, which defines a class of colored-noise baths. This leads to an intrinsically non-Markovian CM, where each ancilla (bath subunit) collides repeatedly with S at different steps. We discuss the illustrative example of an atom in front a mirror in the regime of non-negligible retardation times.

Structural studies of the yeast transcription termination complex Nrd1-Nab3-Sen1

description: The Nrd1-Nab3-Sen1 (NNS) complex carries out the RNA polymerase II (Pol II) transcription termination of non-coding RNAs (ncRNAs) in yeast, although the detailed interactions among its subunits remain obscure. In this dissertation, we have identified three sequence motifs in Sen1 that mediate direct interactions with the Pol II CTD interaction domain (CID) of Nrd1, determined the crystal structures of these Nrd1 interaction motifs (NIMs) bound to the CID, which elucidated the molecular basis for their recognition by Nrd1 CID, and characterized the interactions in vitro and in yeast. Although the Sen1 NIMs are not essential for supporting viability from the in vivo studies, termination defects were observed from NIM deletions in a reporter assay. In addition, the conservation of Sen1 NIMs suggests these interactions are very likely to promote NNS function.
      This dissertation also describes the structural studies of the flowering time control protein FPA in plants, which regulates the alternative 3’-end processing of the FLOWERING LOCUS C (FLC) antisense RNA. FPA belongs to the split ends (SPEN) family of proteins, which contain N-terminal RNA recognition motifs (RRMs) and a SPEN paralog and ortholog C-terminal (SPOC) domain. The SPOC domain is highly conserved among FPA homologs in plants, but the conservation with the domain in other SPEN proteins is much lower. We have determined the crystal structure of Arabidopsis thaliana FPA SPOC domain at 2.7 Å resolution. Structural and sequence analyses identify a surface patch that is conserved among plant FPA homologs. Mutations of two residues in this surface patch did not disrupt FPA functions, suggesting that either the SPOC domain is not required for the role of FPA in regulating RNA 3’-end formation or the functions of the FPA SPOC domain cannot be disrupted by this combination of mutations.

description: The exact analytical formulas for the transverse momentum distributions of the Bose-Einstein, Fermi-Dirac and Maxwell-Boltzmann statistics of particles with nonzero mass in the framework of the Tsallis normalized and Tsallis unnormalized (also known as Tsallis-1 and Tsallis-2) statistics have been consistently derived. The final exact results were expressed in terms of the series expansions in the integral representation. The zeroth term approximation to both quantum and classical statistics of particles has been introduced. We have revealed that the phenomenological classical Tsallis distribution (widely used in high energy physics) is equal to the distribution of the Tsallis unnormalized statistics in the zeroth term approximation, but the phenomenological quantum Tsallis distributions (introduced by definition on the basis of the generalized entropy of the ideal gas) do not correspond to the distributions of the Tsallis statistics. We have found that in the ranges of the entropic parameter relevant to the processes of high-energy physics ($q<1$ for Tsallis-1 and $q>1$ for Tsallis-2) the Tsallis statistics is divergent. Therefore, to obtain physical results, we have regularized the Tsallis statistics by introducing an upper cut-off in the series expansion. The exact numerical results for the Bose-Einstein, Fermi-Dirac and Maxwell-Boltzmann statistics of particles in the Tsallis normalized and unnormalized statistics have been obtained. We observed that the exact results of the Tsallis statistics strongly enhanced the production of high-$p_{T}$ hadrons in comparison with the usual phenomenological Tsallis distribution function at the same values of $q$. The $q$-duality of the Tsallis normalized and unnormalized statistics for the massive particles was studied.

description: The dynamics of band-gap renormalization and gain build-up in monolayer MoTe$_2$ is investigated by evaluating the non-equilibrium Dirac-Bloch equations with the incoherent carrier-carrier and carrier-phonon scattering treated via quantum-Boltzmann type scattering equations. For the case where an approximately $300$ fs-long high intensity optical pulse generates charge-carrier densities in the gain regime, the strong Coulomb coupling leads to a relaxation of excited carriers on a few fs time scale. The pump-pulse generation of excited carriers induces a large band-gap renormalization during the time scale of the pulse. Efficient phonon coupling leads to a subsequent carrier thermalization within a few ps, which defines the time scale for the optical gain build-up energetically close to the low-density exciton resonance.

description: Graph kernels have become an established and widely-used technique for solving classification tasks on graphs. This survey gives a comprehensive overview of techniques for kernel-based graph classification developed in the past 15 years. We describe and categorize graph kernels based on properties inherent to their design, such as the nature of their extracted graph features, their method of computation and their applicability to problems in practice. In an extensive experimental evaluation, we study the classification accuracy of a large suite of graph kernels on established benchmarks as well as new datasets. We compare the performance of popular kernels with several baseline methods and study the effect of applying a Gaussian RBF kernel to the metric induced by a graph kernel. In doing so, we find that simple baselines become competitive after this transformation on some datasets. Moreover, we study the extent to which existing graph kernels agree in their predictions (and prediction errors) and obtain a data-driven categorization of kernels as result. Finally, based on our experimental results, we derive a practitioner's guide to kernel-based graph classification.

description: Excerpts from the report: Date consumption in the United States averaged approximately 70 million pounds a year in 1954-56, or slightly less than one-half pound per capita. Imports, chiefly from Iraq, provided approximately 60 percent of this amount. The date palm requires a very hot, dry climate which limits the commercial production of dates in the United States principally to certain desert valleys of southern California. The relatively young domestic date industry increased the production of dates rather steadily from 1 million pounds in 1926 to an average of over 40 million pounds in 1955-58. Marketing problems of the date industry have grown more important in recent years as production increased sharply and prices fell. This report presents information on marketing practices and on packing plant organization and costs as a basis for consideration of possible adjustments by members of the industry. The 18 plants supplying information for this study handled 90 percent of the California date crop, with volume per plant varying from less than 10,000 pounds to several million pounds per year. The three largest plants handled approximately 70 percent of the total crop.

description: A major research project to investigate methods to determine the susceptibility of mine tailings to static liquefaction began in late 2017. The project is jointly funded by the Australian Research Council and six industry partners, and has four participating Australian Universities. This paper describes the key objectives of the project and the findings to date. Although the information is preliminary in nature, significant progress has already been made, as summarized in the paper. Field sampling has been completed at six sites designated by sponsoring partners, complemented by CPTu testing. The project includes extensive element testing, calibration chamber testing and geotechnical centrifuge testing using tailings from the sponsor sites recovered during the field work. Additional work includes numerical modeling, focusing on use of the Discrete Element Method for understanding the micromechanical behavior of material in both element tests. A key feature of the project is to improve and validate use of the CPTu for assessing liquefaction susceptibility of tailings. A novel aspect of this project is the investigation of methods for interpretation of CPTu data obtained above the phreatic surface, i.e. within unsaturated material. Preliminary information on some calibration chamber tests on unsaturated tailings from one of the sponsor sites is also presented.

description: Analytical formulas are presented describing a generic singularity inside the static spherically symmetric black holes in the SU(2) Einstein-Yang-Mills-Higgs theories with triplet or doublet Higgs field. The singularity is spacelike and exhibits a `power-low mass inflation'. Alternatively this asymptotic may be interpreted as a pointlike singularity with a non-vanishing shear in the Kantowski-Sachs anisotropic cosmology.

description: Objective: Sleep-related hypermotor epilepsy (SHE) is a sleep-related focal epilepsy which is often misdiagnosed. Despite active pharmacological therapy in the management of this disorder, satisfactory seizure control still cannot be achieved. Therefore, the aim of the present study was to identify this disorder among people who were seeking medical advice at Cairo University Epilepsy Unit (CUEU), characterizing its clinical, electroencephalographic and imaging features besides identifying possible indicators of inadequate seizure control on drug-therapy. Patients and methods: This study was carried out on 26 patients with SHE who were subjected to detailed history taking and examination in addition to home video recording, video electroencephalographic (EEG) monitoring and brain imaging. Ictal semiology and EEGs were reviewed and analyzed by experienced neurologists. Results: SHE is an uncommon sleep-related focal epilepsy. In our series, median age of the patients was 18.5 years. It is characterized by being sporadic, with often frontal lobe seizure onset (14/26, 53.8%) and with occasional occurrence in wakefulness. Adolescence age at disease onset (11 years, 6–15), duration less than 1 min, clustering, lack of auras and often uninformative brain imaging (22/25, 88%) are all documented features. Moreover, it has a relatively poor outcome on pharmacological therapy (16/26, 61.5%). Longer disease duration (>4.5 years) was a significant feature of the patients exhibiting inadequate seizure control. Conclusions: Our data show relatively poor prognosis of SHE on medical therapy. Its outcome is significantly related to disease duration at the time of diagnosis. Abbreviation: SHE = Sleep related hypermotor epilepsy

description: Bestrophins are a family of calcium (Ca²⁺) -activated chloride (Cl⁻) channels (CaCCs) with functional importance in eye physiology. Mutations to the VMD2 gene, which encodes the Best1 protein, cause an array of degenerative eye disorders called bestrophinopathies, which result from aberrant CaCC activity of the Best1 channel in the pigmented epithelium of the retina. While there are four bestrophin paralogs in mammals (Best1-4), the only current structures are of Best1 homologs. The structure of the prokaryotic homolog of Best1 from Klebsiella pneumonia (KpBest) was previously solved in this lab, representing the first structure of a Best1 homolog at the time. This initial study laid the foundational groundwork in the field and contributed significant knowledge to understanding the bestrophin structure-function relationship. Nevertheless, significant questions remain regarding bestrophin function, such as the molecular determinants underlying its Ca²⁺-dependent gating and anion selectivity. This dissertation uses single-particle cryogenic electron microscopy paired with electrophysiology to probe the structure-function relationship of mammalian bestrophins under different buffer conditions and reveals conformational dynamics involved in gating of wild-type channels. Key regions of the channel contributing to its function are described at the atomic level leading to development of a gating model to explain Ca²⁺-dependent activation and inactivation in mammalian bestrophins.

description: We propose a discrete spacetime formulation of quantum electrodynamics in one-dimension (a.k.a the Schwinger model) in terms of quantum cellular automata, i.e. translationally invariant circuits of local quantum gates. These have exact gauge covariance and a maximum speed of information propagation. In this picture, the interacting quantum field theory is defined as a "convergent" sequence of quantum cellular automata, parameterized by the spacetime lattice spacing---encompassing the notions of continuum limit and renormalization, and at the same time providing a quantum simulation algorithm for the dynamics.
