description: We study the Tevatron search potential for minimal supergravity (mSUGRA) and find two observables which reveal complementary information on the mSUGRA parameter space: the ``gold-plated'' decays of charginos/neutralinos to trilepton final states and the rare decay B_s-> mu^+ mu^-. For the universal gaugino mass, M_{1/2} below 250 GeV and for the universal scalar fermion mass, M_0 outside of 200-370 GeV we face a ``no-lose'' situation for the Tevatron: If tan(beta) < 30, the Tevatron has a chance to see the trilepton events but not B_s -> mu^+ mu^- during Run IIa, whereas for larger tan(beta) the trilepton events become invisible (at least with an integrated luminosity of 2 fb^{-1}) while B_s -> mu^+ mu^- is enhanced to an observable level. For this study we perform an updated analysis of the trilepton signature which includes the full set of the decay matrix elements and spin correlations. This leads to a new, more promising search reach for the Tevatron.

description: In this article we prove two formulas for the topological entropy of an F-optical Hamiltonian flow induced by a C^{\infty} Hamiltonian, where F is a Lagrangian distribution. In these formulas, we calculate the topological entropy as the exponential growth rate of the average of the determinant of the differential of the flow, restricted to the Lagrangian distribution or to a proper modification.

description: Joint deconvolution and segmentation of ultrasound images is a challenging problem in medical imaging. By adopting a hierarchical Bayesian model, we propose an accelerated Markov chain Monte Carlo scheme where the tissue reflectivity function is sampled thanks to a recently introduced proximal unadjusted Langevin algorithm. This new approach is combined with a forward-backward step and a preconditioning strategy to accelerate the convergence, and with a method based on the majorization-minimization principle to solve the inner nonconvex minimization problems. As demonstrated in numerical experiments conducted on both simulated and in vivo ultrasound images, the proposed method provides high-quality restoration and segmentation results and is up to six times faster than an existing Hamiltonian Monte Carlo method.

International tailings failures and best available technology
Creators: name: Boswell, Jeremy

Publisher: name: The University of British Columbia
Year: 2017

description: Recent events in western Canada within the last year have focused our attention as geotechnical engineers within the mining industry: • A plunging oil price against a backdrop of already depressed mining commodity prices has applied pressure to the process of tailings and geotechnical design. • We witnessed one of the largest tailings failures worldwide ever (in terms of volume), after which the Expert Panel who were appointed to investigate the failure concluded that the “dominant contribution to the failure resides in the design.” This is perhaps an important time for us to pause and reflect on our work in tailings engineering, with a somewhat broader international perspective, and to ponder a few questions: 1. What were some of the salient tailings failures around the world over the past 50 years? 2. What are the leading mechanisms of failure for tailings facilities? 3. In response to the call for the adoption of Best Available Technology, how do we define Best Available Technology (BAT) for the tailings industry? 4. What foundational principles might point us to BAT? 5. What tailings technologies should we be considering more closely, and how could these technologies be applied to reduce our exposure to risk? 6. What changes could be made to introduce and advance best available technology in all aspects of tailings engineering? In this paper the authors offer their insights in reply to the questions posed above.

description: Das Lob bei Festen der Erinnerung ist immer am richtigen Platze, ist es doch der einzig mögliche Ausdruck des Glücks, der Dankbarkeit, der Anerkennung für geleistete Dienste, für das gegebene Vorbild, für erwiesene Menschlichkeit, für die Übertragung von Generation zu Generation eines großen nachahmungswürdigen Beispiels das wir feiern, in der Hoffnung uns auch selbst daran zu bilden und erbauen. Es ist das Setzen eines Denkmals, einer der schönsten Aufgaben der Kunst die leider jetzt nicht oft gewürdigt wird, weil man glaubt, daß Denkmäler, die ja ihrer Natur entsprechend, rühmliches über den Gegenstand ihrer Verherrlichung aussagen, lügen. Doch dem ist nicht so. Sie rühmen ja nur was sie zeigen und lügen oder betrügen nur dann wenn das, was sie zeigen nicht schön und lobenswert, sondern nur eitel und keck oder gar unmenschlich ist, auch dann wenn die Künstler und ihr Publikum eben gerade das Unmenschliche für lobenswert halten und das Häßliche, die Härte, für Tapferkeit ausgeben. Es mag ja sein, daß sie es nicht besser wissen und wir müssen alle in Demut einsehen, daß wir, wenn wir Werturteile fallen, uns irren können, ja zum unweigerlichen Irrtum verurteilt wären, wenn uns nicht, aus dem großen Schatz der Vergangenheit, Kunst und Geschichte Vorbilder zeigten, die uns besser begreifen lassen, was die Kultur des verdienten Ruhmes und der Liebe uns zu bieten hat und wir erkennen, wie sehr wir diesem historischen Betrachten das, wenn wir einmal mit ihm angefangen haben, uns nicht mehr los läßt, für die Gestaltung unseres eigenen Lebens in Dankbarkeit verpflichtet sind.

description: Given a vector bundle $E$ on a smooth projective curve or surface $X$ carrying the structure of a $V$-twisted Hitchin pair for some vector bundle $V$, we observe that the associated tautological bundle $E^{[n]}$ on the punctual Hilbert scheme of points $X^{[n]}$ has an induced structure of a $((V^\vee)^{[n]})^\vee$-twisted Hitchin pair, where $(V^\vee)^{[n]}$ is a vector bundle on $X^{[n]}$ constructed using the dual $V^\vee$ of $V$. In particular, a Higgs bundle on $X$ induces a logarithmic Higgs bundle on the Hilbert scheme $X^{[n]}$. We then show that the known results on stability of tautological bundles and reconstruction from tautological bundles generalize to tautological Hitchin pairs.

A non-intrusive reduced-order modeling method using polynomial chaos expansion

description: We propose a non-intrusive reduced-order modeling method based on proper orthogonal decomposition (POD) and polynomial chaos expansion (PCE) for stochastic representations in uncertainty quantification (UQ) analysis. Firstly, POD provides an optimally ordered basis from a set of selected full-order snapshots. Truncating this optimal basis, we construct a reduced-order model with undetermined coefficients. Then, PCE is utilized to approximate the coefficients of the truncated basis. In the proposed method, we construct a PCE using a non-intrusive regression-based method. Combined with the model reduction ability of POD, the proposed method efficiently provides stochastic representations in UQ analysis. To investigate the performance of the proposed method, we provide three numerical examples, i.e., a highly nonlinear analytical function with three uncertain parameters, two-dimensional (2D) heat-driven cavity flow with a stochastic boundary temperature, and 2D heat diffusion with stochastic conductivity. The results demonstrate that the proposed method significantly reduces the computational costs and storage requirements that arise due to high-dimensional physical and random spaces. While demonstrating a similar accuracy with that of the classical full-PCE in predicting statistical quantities. Furthermore, the proposed method reasonably predict the outputs of the full order model using only a few snapshots.

description: Viruses require a host cell to replicate and proliferate; upon infection they appropriate host resources and molecular machines. Specifically, viruses use ribosomes of the host to translate the information in their genome. Some viruses with single-stranded RNA genomes contain highly structured non-coding regions of RNA called internal ribosome entry sites (IRESs) which are used to hijack the host’s ribosomes through a non-canonical cap-independent initiation pathway. Canonical translation initiation is a highly complex and regulated process: at least a dozen translation factors are necessary, and it is the rate-limiting step in eukaryotic translation. Viruses containing an IRES forgo canonical eukaryotic translation initiation factors and bypass some steps of canonical translation initiation by mimicking part of the host’s initiation machinery. The simplest among these IRESs are found in the intergenic region (IGR) of viruses in the family Dicistroviridae. These type IV IRESs from dicistroviruses have been structurally characterized in great detail in using the cricket paralysis virus (CrPV) and Israeli Acute Paralysis Virus (IAPV). To better understand how structure affects the function of these type IV IRESs, using single-particle cryo-electron microscopy (cryo-EM), we have characterized a recently discovered IRES found in the IGR of the genome of Nedicistrovirus (NediV). Four complexes that represent each step in the alternative translation initiation mechanism were prepared and analyzed to solve the 3D structure and characterize the mechanism by which the NediV-IRES captures host ribosomes. With this, we were able to understand how the shorter stem-loop V (SL-V) of NediV-IRES impacts the well-characterized interaction of SL-V with eukaryotic small subunit ribosomal protein 25 (eS25) (Landry et al., 2009), which is important for the IRES:40S complex formation. This shortened stem-loop has been shown to fold in a way that does not support stable binding to the small ribosomal subunit (40S) and subsequent recruitment of the large ribosomal subunit (60S). NediV-IRES, rather, relies on direct recruitment of the 80S ribosome, which has been seen more commonly at low concentrations of Mg²⁺ for CrPV-IRES (Petrov et al., 2016). Solved structures also suggest that upon loading, NediV-IRES skips the first eEF2-dependent pseudo-translocation step necessary to bind to the ribosomal P site without the need of eEF2. Because of their simplicity, these type IV IRESs represent a robust potential tool for cell-free and vector-driven translation. Due to these structural and mechanistic differences observed, we propose that NediV-IRES, along with the NediV-like Antarctic picorna-like virus 1 (APLV-1)-IRES (Lu, 2019), represents a novel type IV IRES subclass.

description: Many temporary facilities are required during on-site construction operations of most projects. They must be situated in convenient locations as ease of access can have a significant impact on the efficiency and safety of the construction project. The feasible locations and layouts that satisfy all specified conditions and constraints can still be very large in number; thus, optimal layout planning can be very challenging, even for experienced engineers. A model for solving the construction site layout problem (CSLP) is proposed. A grid system is implemented to simulate sites and facilities more realistically. This model incorporates an algorithm that imitates and calculates the distances of typical travel paths of workers between a pair of facilities during construction operations. In addition, Particle Swarm Optimisation is adopted to solve the problem model. The prototype program was developed and tested on a real construction project case. The results show that the model was able to lay out the site efficiently and optimally. The resulting layouts were better than those from engineers and conventional distance calculation methods.

Thirteen toroidal states with spin $I$ ranging from 0 to 56$\hbar$ are obtained, and their stabilities against particle emissions are studied by analyzing the density distributions and potentials. The excitation energies of the toroidal states at $I=28$, 36, 44$\hbar$ reasonably reproduce the observed three resonances extracted from the 7-$α$ de-excitation of $^{28}$Si. The $α$ clustering of these toroidal states is supported by the $α$-localization function.

description: IoT Edge intelligence requires Convolutional Neural Network (CNN) inference to take place in the edge devices itself. ARM big.LITTLE architecture is at the heart of prevalent commercial edge devices. It comprises of single-ISA heterogeneous cores grouped into multiple homogeneous clusters that enable power and performance trade-offs. All cores are expected to be simultaneously employed in inference to attain maximal throughput. However, high communication overhead involved in parallelization of computations from convolution kernels across clusters is detrimental to throughput. We present an alternative framework called Pipe-it that employs pipelined design to split convolutional layers across clusters while limiting parallelization of their respective kernels to the assigned cluster. We develop a performance-prediction model that utilizes only the convolutional layer descriptors to predict the execution time of each layer individually on all permitted core configurations (type and count). Pipe-it then exploits the predictions to create a balanced pipeline using an efficient design space exploration algorithm. Pipe-it on average results in a 39% higher throughput than the highest antecedent throughput.

Mutagenesis

description: Most eukaryotic pre-mRNAs undergo 3′-end cleavage and polyadenylation prior to their export from the nucleus. A large number of proteins in several complexes participate in this 3′-end processing, including cleavage and polyadenylation specificity factor (CPSF) in mammals. The CPSF can be further divided into two sub-complexes: mPSF (mammalian polyadenylation specificity factor) which recognizes the AAUAAA polyadenylation signal (PAS) in the pre- mRNA, and mCF (mammalian cleavage factor) which cleaves the RNA. mPSF consists of CPSF160, CPSF30, WDR33, and hFip1. This thesis shows that AAUAAA PAS is recognized with ∼3 nM affinity by the CPSF160–WDR33–CPSF30 ternary complex, while the proteins alone or the binary complexes do not bind the PAS with high affinity. Furthermore, it is shown that mutations of residues in CPSF30 that have van der Waals interactions with the bases of the PAS lead to a sharp reduction in the affinity. Finally, variations of the AAUAAA or removing the bases downstream also reduce the binding significantly. This thesis goes on to characterize the structure of the CPSF30—hFip1 complex, which was not observed in the previous EM structures of the mPSF. It was known that CPSF30 ZF4–ZF5 recruits the hFip1 subunit of CPSF, although the details of this interaction have not been characterized. Here we report the crystal structure of human CPSF30 ZF4–ZF5 in complex with residues 161–200 of hFip1 at 1.9 Å. Unexpectedly, the structure reveals one hFip1 molecule binding to each ZF4 and ZF5, with a conserved mode of interaction. Mutagenesis studies confirm that the CPSF30–hFip1 complex has 1:2 stoichiometry in vitro. Mutation of each binding site in CPSF30 still allows one copy of hFip1 to bind, while mutation of both sites abrogates binding. Our fluorescence polarization binding assays show that ZF4 has higher affinity for hFip1, with a Kd of 1.8 nM. We also demonstrate that two copies of the catalytic module of poly(A) polymerase (PAP) are recruited by the CPSF30–hFip1 complex in vitro, and both hFip1 binding sites in CPSF30 can support polyadenylation.

description: The deposition of conventional thickened tailings across the international mining industry has encountered many operational challenges over the years. These include variation in feed, solids content, beach establishment, stability and capacity constraints, drainage, consolidation, supernatant and fines. High quality design and operation of thickeners can prevent many of the problems encountered in tailings deposition. However, despite their best efforts, tailings managers still encounter significant challenges during deposition. This paper outlines the elements of a successful thickened tailings deposition plan and describes some of the interventions available to the tailings designer or operator, which have been successfully implemented as remedies. These include control of slurry relative density, elimination of excess water, development of a conservative deposition cycle which takes account of weather, discharge control, drainage and decanting techniques, and planning for off-specification events. It also presents potential issues with thickener implementation within the Oil Sands industry due to the nature of feed and material variability, difficulties in depositing material in the short term and long term and drying material efficiently.

description: Public sector housing is important. Its particular importance in Glasgow derives from the fact that over 57% of households in the City are Local Authority tenants. This thesis examines a new project being set up by Glasgow District Council in three high stress areas of its housing stock. The project, called the Community Ownership Programme, is the first of its kind in Scotland. It involves the formation of par-value housing co-operatives by the tenants, who will purchase their houses collectively from the Council and subsequently manage them along co-operative lines. The study begins with a brief chapter establishing the general context of the public sector in Britain, touching briefly on housing policies at a national level. Against this background. Chapter 2 examines the problems of difficult-to-let estates, their characterising factors and some fundamental causes. It then goes on to discuss some significant reports in this field and the remedial action they suggest. Finally some conclusions are drawn about future policies. Chapter 3 brings this discussion down to the local context. The twofold nature of Glasgow's housing problem is described, setting the scene for the next chapter. Against this framework. Chapter 4 examines the influences actually brought to bear in shaping the Community Ownership Programme, focussing particularly on the way in which the District Council have drawn on the resources and experience available to develop a new model to improve public sector housing. In Chapter 5, this model is discussed in detail. Par-value cooperatives are described, as are the three main factors involved - the tenants, the dwellings and finance. Finally the legal and financial procedures of establishing a co-operative are examined. Three detailed case studies are then presented in Chapter 6. In each of these, a preliminary sketch is given of the background, followed by a narrative account of the development of the co-operative and the proposed improvements. In Chapter 7 an attempt is made to tackle the difficult question of evaluation. Chapter 8 brings together and reviews some of the findings of the case studies in relation to the future development of the co-operatives. The analysis focusses particularly on two variables which are critical to the expansion of the project, namely community action capacity and continued political feasibility. This is followed by some concluding remarks.

description: A More flavored Higgs boson arises when the flavor structure encoded in SUSY extensions of the SM is transmited to the Higgs sector. The flavor-Higgs transmition mechanism can have a radiative or mixing origin, as it is illustrated with several examples, and can produce interesting Higgs signatures that can be probed at future high-energy colliders. Within the MSSM, the flavor mediation mechanism can be of radiative type, as it is realized trhough gaugino-slepton loops, which transmit the flavor structture of the soft-breaking sector to the Higgs bosons. In particular we focus on evaluating the contributions from the general trilinear terms to the lepton flavor violating Higgs (LFV) vertices. On the other hand, as an example of flavor mediation through mixing, we discuss an E_6 inspired multi-Higgs model, with an abelian flavor symmetry, where LFV as well as lepton flavor conserving Higgs effects are found to arise, though in this case at tree-level. We find that Tevatron and LHC can provide information on the flavor structure of these models through the detection of the LFV higgs mode h-> tau+mu, while NLC can perform high-precision measurements of the LFC mode h-> tau tau.

description: A measurement is presented of electroweak (EW) production of a W boson in association with two jets in proton-proton collisions at $\sqrt{s} =$ 13 TeV. The data sample was recorded by the CMS Collaboration at the LHC and corresponds to an integrated luminosity of 35.9 fb$^{-1}$. The measurement is performed for the $\ellν$jj final state (with $\ellν$ indicating a lepton-neutrino pair, and j representing the quarks produced in the hard interaction) in a kinematic region defined by invariant mass $m_\mathrm{jj}$ $>$ 120 GeV and transverse momenta $p_\mathrm{T j}$ $>$ 25 GeV. The cross section of the process is measured in the electron and muon channels yielding $σ_\mathrm{EW}$(Wjj) = 6.23 $\pm$ 0.12 (stat) $\pm$ 0.61 (syst) pb per channel, in agreement with leading-order standard model predictions. The additional hadronic activity of events in a signal-enriched region is studied, and the measurements are compared with predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. Limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are $-$2.3 $

description: For a quantum Lie algebra $Γ$, let $Γ^\wedge$ be its exterior extension (the algebra $Γ^\wedge$ is canonically defined). We introduce a differential on the exterior extension algebra $Γ^\wedge$ which provides the structure of a complex on $Γ^{\wedge}$. In the situation when $Γ$ is a usual Lie algebra this complex coincides with the "standard complex". The differential is realized as a commutator with a (BRST) operator $Q$ in a larger algebra $Γ^\wedge[Ω]$, with extra generators canonically conjugated to the exterior generators of $Γ^{\wedge}$. A recurrent relation which defines uniquely the operator $Q$ is given.

description: IEA Wind Task 19 considers wind turbine performance testing in icing climates as a keyelement to mitigate risks when developing wind farms in cold climates and for acceleratingwind turbine technology improvements in cold climate conditions. The first edition of thePerformance Warranty guidelines for wind turbines in icing climates was published in May2018. The aim of this second edition is to present and further detail the most promisingavailable options on how wind turbines with icing climate adaptations can be warranted andtested with affordable and reasonably accurate test methods.It is recommended that an ice protection system (“IPS”) should be considered as part of theprocurement process within the turbine contract and to include a turbine performance warrantyfor icing climates. The IPS should be viewed as an integral sub-system of the turbine, subjectto similar level of expectations and service as for any other sub-system in the wind turbine andas such should carry the same warranty protection as the turbine (e.g., related to productperformance and availability).A turbine performance warranty for a wind turbine in icing climate should define a test methoddesigned for measuring a clearly defined performance criteria within the IPS’s operationalenvelope at reasonable cost, accuracy and test duration. The performance criteria may differdepending on the chosen test method. Consequences for failed tests should be aimed firstly atrectifying and improving turbine performance and secondly at providing liability coverage.Three different turbine-level IPS performance test methods have been identified as the mostpromising and commonly used in the industry. The three turbine performance warranty testsare:

 

The turbine self-comparison test – self-comparison of a test turbines performanceduring icing events and outside of icing events .

The side-by-side comparison test – comparison of two or more turbines positioned insimilar locations, with similar wind and icing climate, where one wind turbine is runwith an active IPS and the other with a deactivated IPS.

The power performance test – similar to IEC 61400-12, based on the standard powercurve testing standard.
Structural Studies of the Integrator Complex -- pre-UsnRNA 3'-end Processing Machinery

description: The Integrator complex (INT) is a metazoan-specific group of proteins associated with RNA polymerase II (Pol II) that has important functions in the 3'-end processing of noncodng RNAs, including uridine-rich small nuclear RNA (UsnRNA) and enhancer RNA (eRNA). Recently, INT has also been reported to be involved in Pol II transcriptional regulation of protein-encoding genes. INT contains at least 14 subunits, but the function of each subunit is difficult to predicted, because most subunits lack identifiable domains and display little similarity with other proteins. The endonuclease activity of INT is carried out by its subunit 11 (IntS11), which belongs to the metallo--lactamase superfamily and is a paralog of CPSF-73, the endonuclease for pre-mRNA 3'-end processing. IntS11 forms a stable complex with INT subunit 9 (IntS9) through their C-terminal domains (CTDs). This dissertation describes the crystal structure of the IntS9-IntS11 CTD complex at 2.1-Å resolution and summaries the structure-based biochemical and functional studies. The complex is composed of a continuous nine-stranded -sheet with four strands from IntS9 CTD and five from IntS11 CTD. Highly conserved residues are located in the interface between the two CTDs. The structural observations on the complex are confirmed by yeast two-hybrid assays and coimmunoprecipitation experiments. Functional studies demonstrate that the Int9-IntS11 interaction is crucial for proper INT function in snRNA 3'-end processing.
      The dissertation also presents the structural studies of a newly found mammalian mRNA deNADding enzyme, Nudt12. We determined the crystal structure of mouse Nudt12 in complex with the deNADding product AMP and three Mg2+ ions at 1.6-Å resolution. The structure provides exquisite insights into the molecular basis of the deNADding activity within the NAD pyrophosphate. Previous studies have reported that NAD-capped mRNAs in mammalian cells are hydrolyzed by the DXO deNADding enzyme. Together with biochemical and functional studies, we demonstrate that Nudt12 is a second mammalian deNADding enzyme structurally and mechanistically distinct from DXO and targets different RNAs.

description: We consider the following eigenvalue optimization problem: Given a bounded domain $Ω\subset\R^n$ and numbers $α\geq 0$, $A\in [0,|Ω|]$, find a subset $D\subsetΩ$ of area $A$ for which the first Dirichlet eigenvalue of the operator $-Δ+ αχ_D$ is as small as possible. We prove existence of solutions and investigate their qualitative properties. For example, we show that for some symmetric domains (thin annuli and dumbbells with narrow handle) optimal solutions must possess fewer symmetries than $Ω$; on the other hand, for convex $Ω$ reflection symmetries are preserved. Also, we present numerical results and formulate some conjectures suggested by them.

description: Strain engineering of graphene takes advantage of one of the most dramatic responses of Dirac electrons enabling their manipulation via strain-induced pseudo-magnetic fields. Numerous theoretically proposed devices, such as resonant cavities and valley filters, as well as novel phenomena, such as snake states, could potentially be enabled via this effect. These proposals, however, require strong, spatially oscillating magnetic fields while to date only the generation and effects of pseudo-gauge fields which vary at a length scale much larger than the magnetic length have been reported. Here we create a periodic pseudo-gauge field profile using periodic strain that varies at the length scale comparable to the magnetic length and study its effects on Dirac electrons. A periodic strain profile is achieved by pulling on graphene with extreme (>10%) strain and forming nanoscale ripples, akin to a plastic wrap pulled taut at its edges. Combining scanning tunneling microscopy and atomistic calculations, we find that spatially oscillating strain results in a new quantization different from the familiar Landau quantization observed in previous studies. We also find that graphene ripples are characterized by large variations in carbon-carbon bond length, directly impacting the electronic coupling between atoms, which within a single ripple can be as different as in two different materials. The result is a single graphene sheet that effectively acts as an electronic superlattice. Our results thus also establish a novel approach to synthesize an effective 2D lateral heterostructure - by periodic modulation of lattice strain.
