description: BPS monopoles in N=2 SUSY theories may lead to monopole condensation and confinement. We have found that supersymmetric black holes with non-vanishing area of the horizon may stabilize the moduli in theories where the potential is proportional to the square of the graviphoton central charge. In particular, in known models of spontaneous breaking of N=2 to N=1 SUSY theories, the parameters of the electric and magnetic Fayet--Iliopoulos terms can be considered proportional to electric and magnetic charges of the dyonic black holes. Upon such identification the potential is found to be proportional to the square of the black hole mass. The fixed values of the moduli near the black hole horizon correspond exactly to the minimum of this potential. The value of the potential at the minimum is proportional to the black hole entropy.

Louvicourt mine : a recent mine closure case study

description: The Louvicourt sulphide deposit, located 20 km east of Val-d’Or, Quebec, was discovered in 1989. Production of copper and zinc concentrates was initiated in 1994 and ceased in 2005 due to exhaustion of the ore body. The ore and some waste rock from mine development were acid-generating. Early in the mine planning, issues related to protection of the environment and to mine closure were considered. To limit environmental impacts related to acid-generating milling residues, it was decided to take advantage of the paste backfill plant by using 55% of the milling residues to incorporate them in the cemented backfill. The latter was used for ground support in mined stopes. Sub-aqueous disposal of mill tailings (remaining 45%) was selected at the project design stage to inhibit acid generation. An artificial pond was built in a suitable area located 8 km northwest of the mine. The pond is confined by natural topography and dikes. A polishing pond was added to improve final effluent quality. The retained concept involves maintaining the dikes and water cover in perpetuity. As required by the Quebec Environmental Act, an Environmental Site Assessment was completed following mine closure. Based on results obtained at Louvicourt, 76,000 m³ of backfill material around the infrastructures were contaminated by dust containing copper and zinc due to the routine handling of ore, waste and concentrates. In addition, part of a barren waste pile was slightly acid-generating (66,000 m³). The site was rehabilitated in 2007 by excavating and placing these materials in the underground workings and on an existing acid-generating waste rock pile that remains to be remediated by installing an impervious cover. Five years after mine closure, the water quality at the tailings pond is good and meets the requirements defined by Quebec Directive 019 on the mining industry. Water in the polishing pond meets Quebec fresh water quality criteria (acute toxicity). The tailings impoundment system is proving to be very efficient at preventing acid generation. Over the long-term, it is anticipated that some portions of the site can be returned to the crown.

description: Distortions of the $\sqrt3\times\sqrt3$ Sn/Ge(111) and Sn/Si(111) surfaces are shown to reflect a disproportionation of an integer pseudocharge, $Q$, related to the surface band occupancy. A novel understanding of the $(3\times3)$-1U (``1 up, 2 down'') and 2U (``2 up, 1 down'') distortions of Sn/Ge(111) is obtained by a theoretical study of the phase diagram under strain. Positive strain keeps the unstrained value Q=3 but removes distorsions. Negative strain attracts pseudocharge from the valence band causing first a $(3\times3)$-2U distortion (Q=4) on both Sn/Ge and Sn/Si, and eventually a $(\sqrt3\times\sqrt3)$-3U (``all up'') state with Q=6. The possibility of a fluctuating phase in unstrained Sn/Si(111) is discussed.

description: Understanding the determinants of improved agricultural technology adoption is an important component of increasing agricultural productivity and incomes of smallholders to reduce poverty and hunger. In this paper, particular attention is given to the identification and promotion of productivity and resilience enhancing agricultural practices. Although numerous seminal reviews of this literature have been published, most of these were theoretical or conceptual reviews and focus on earlier literature from continents other than Africa, which is the continent facing the biggest productivity challenge now. The authors synthesize the findings of this literature with a focus on Africa using a meta-data set that brings together the results of 168 recently published papers. They find that most of this literature focuses on agronomic practices and that agroforestry and livestock related studies make up less than one fifth of the total published papers. Eleven determinants, primarily those related to information access, wealth indicators and tenure security, are found to increase adoption more than chance would dictate in the literature. The findings provide evidence to support recommendations for future policy and research.
Alternating Weak Automata from Universal Trees

Publisher: name: arXiv
Year: 2019
Subjects: subject: Formal Languages and Automata Theory (cs.FL)

description: An improved translation from alternating parity automata on infinite words to alternating weak automata is given. The blow-up of the number of states is related to the size of the smallest universal ordered trees and hence it is quasi-polynomial, and only polynomial if the asymptotic number of priorities is logarithmic in the number of states. This is an exponential improvement on the translation of Kupferman and Vardi (2001) and a quasi-polynomial improvement on the translation of Boker and Lehtinen (2018). Any slightly better such translation would (if---like all presently known such translations---it is efficiently constructive) lead to algorithms for solving parity games that are asymptotically faster in the worst case than the current state of the art (Calude, Jain, Khoussainov, Li, and Stephan, 2017; Jurdziński and Lazić, 2017; and Fearnley, Jain, Schewe, Stephan, and Wojtczak, 2017), and hence it would yield a significant breakthrough.

description: The Cumulative Drag Index defined recently by Prasanna has been generalised to include the centrifugal acceleration. We have studied the behaviour of the drag index for the Kerr metric and the Neugebauer-Meinel metric representing a self-gravitating rotating disk and their Newtonian approximations. The similarity of the behaviour of the index for a given set of parameters both in the full and approximated forms, suggests that the index characterises an intrinsic property of spacetime with rotation. Analysing the index for a given set of parameters shows possible constraints on them.

description: Objective: The standard of care for cancer-related venous thromboembolism (VTE) has been low molecular weight heparin (LMWH), but oral anticoagulants are also widely prescribed. This study compared VTE-related healthcare resource utilization and costs of cancer patients treated with anticoagulants. Methods: Claims data from Humana Database (January 1, 2013–May 31, 2015) were analyzed. Based on the first anticoagulant received, patients were classified into LMWH, warfarin, or rivaroxaban cohorts. Characteristics were evaluated during the 6 months pre-index date (i.e. the first VTE); VTE-related resource utilization and costs were evaluated during follow-up. Cohorts were compared using rate ratios, and p-values and 95% confidence intervals were calculated. Healthcare costs were evaluated per-patient-per-year (PPPY) and compared using mean cost differences. Results: A total of 2,428 patients (LMWH: n = 660; warfarin: n = 1,061; rivaroxaban: n = 707) were included. Compared to patients treated with LMWH, patients treated with rivaroxaban had significantly fewer VTE-related hospitalizations, hospitalization days, and emergency room and outpatient visits, resulting in an increase of $12,000 VTE-related healthcare costs PPPY with LMWH vs rivaroxaban. Patients treated with rivaroxaban had significantly lower VTE-related resource utilization compared to patients treated with warfarin; however, VTE-related costs were similar between cohorts. The higher drug costs ($1,519) were offset by significantly lower outpatient (−$1,039) and hospitalization costs (−$522) in rivaroxaban relative to the warfarin cohort. Conclusions: Healthcare resource use and costs associated with VTE treatment in cancer patients are highest with LMWH relative to warfarin and rivaroxaban.

Remarks
As currently constituted, approximately 50 species of this genus occur from Mexico through much of South America, as well as in West Indies. See Figs 29–30 for habitus illustrations. However, the genus includes a rather heterogeneous assemblage of species. Future study will likely show that some species are better placed in other genera (for instance Brucita or Metrogaleruca). Also, new genera will likely need to be described to accommodate some of the species.

description: In this thesis, we construct two QCD based energy loss models to perform quantitative analysis of jet quenching observables in ultra-relativistic nucleus-nucleus collisions at RHIC and the LHC.
      We first build up a perturbative QCD based CUJET2.0 jet flavor tomography model that couples the dynamical running coupling DGLV opacity series to bulk data constrained relativistic viscous hydrodynamic backgrounds. It solves the strong heavy quark energy loss puzzle at RHIC and explains the surprising transparency of the quark-gluon plasma (QGP) at the LHC. The observed azimuthal anisotropy of hard leading hadrons requires a path dependent jet-medium coupling in CUJET2.0 that implies physics of nonperturbative origin.
      To explore the nonperturbative chromo-electric and chromo-magnetic structure of the strongly-coupled QGP through jet probes, we build up a new CUJET3.0 framework that includes in CUJET2.0 both Polyakov loop suppressed semi-QGP chromo-electric charges and emergent chromo-magnetic monopoles in the critical transition regime. CUJET3.0 quantitatively describes the anisotropic hadron suppression at RHIC and the LHC. More significantly, it provides a robust connection between the long wavelength "perfect fluidity'' of the QGP and the short distance jet transport in the QGP. This framework paves the way for ``measuring'' both perturbative and nonperturbative properties of the QGP, and more importantly for probing color confinement through jet quenching.
Conformal and Nonconformal Symmetries in 2d Dilaton gravity

description: We study finite-dimensional extra symmetries of generic 2D dilaton gravity models. Using a non-linear sigma model formulation we show that the unique theories admitting an extra (conformal) symmetry are the models with an exponential potential $V \propto e^{βϕ}$ ($ S ={1\over2π} \int d^2 x \sqrt{-g} [ R ϕ+ 4 λ^2 e^{βϕ} ]$), which include the CGHS model as a particular though limiting ($β=0$) case. These models give rise to black hole solutions with a mass-dependent temperature. The underlying extra symmetry can be maintained in a natural way in the one-loop effective action, thus implying the exact solubility of the semiclassical theory including back-reaction. Moreover, we also introduce three different classes of (non-conformal) transformations which are extra symmetries for generic 2D dilaton gravity models. Special linear combinations of these transformations turn out to be the (conformal) symmetries of the CGHS and $V \propto e^{βϕ}$ models. We show that one of the non-conformal extra symmetries can be converted into a conformal one by means of adequate field redefinitions involving the metric and the derivatives of the dilaton. Finally, by expressing the Polyakov-Liouville effective action in terms of an invariant metric, we are able to provide semiclassical models which are also invariant. This generalizes the solvable semiclassical model of Bose, Parker and Peleg (BPP) for a generic 2D dilaton gravity model.

description: A number of detections have been made in the past few years of gravitational waves from compact binary coalescences. While there exist well-understood waveform models for signals from compact binary coalescences, many sources of gravitational waves are not well modeled, including potential long-transient signals from a binary neutron star post-merger remnant. Searching for these sources requires robust detection algorithms that make minimal assumptions about any potential signals. In this paper, we compare two unmodeled search schemes for long-transient gravitational waves, operating on cross-power spectrograms. One is an efficient algorithm first implemented for continuous wave searches, based on a hidden Markov model. The other is a seedless clustering method, which has been used in transient gravitational wave analysis in the past. We quantify the performance of both algorithms, including sensitivity and computational cost, by simulating synthetic signals with a special focus on sources like binary neutron star post-merger remnants. We demonstrate that the hidden Markov model tracking is a good option in model-agnostic searches for low signal-to-noise ratio signals. We also show that it can outperform the seedless method for certain categories of signals while also being computationally more efficient.

Long-term post-closure surface water and groundwater risk management and subsequent water quality trends at the former Sullivan Mine, Kimberley, BC, Canada

Publisher: name: The University of British Columbia

description: The former Sullivan mine was one of the world's largest producers of lead, zinc and silver, officially closing in 2001 after 92 years of active production. The former mine and mill areas contain large impoundments of tailings, waste rock, and other process wastes as a result of historical mining processes. Environmental controls, site assessment and mitigation measures to manage and protect surface water and groundwater quality have been in place since the 1960s. Large-scale characterization of the surface water and groundwater systems was initiated in the mid 1990s. At the same time, incremental efforts to assess and mitigate mining-related impacts to these resources commenced, including: waste impoundment covers, seepage collection systems, mine de-watering, pumping well networks; and groundwater interception barriers, trenches and sand drains. In addition to these mitigation measures, a comprehensive risk assessment was performed culminating in a site-wide Risk Management Plan with annual surface water and groundwater monitoring programs. Long-term post-closure monitoring at a number of surface water and groundwater monitoring locations since 2001 have provided indicators of improving surface water and groundwater quality across both the former mine and mill areas. These long-term trends have confirmed predictions made through conceptual hydrogeological and geochemical models developed after closure. Monitoring in the tailings impoundments indicated loading to groundwater from acid rock drainage and metal leaching impacts in source areas has been reduced. Monitoring in downgradient areas suggested groundwater capture has been successful in reducing off-site loading. Surface water quality has improved in receiving creeks and rivers. In addition to mitigative measures implemented at the site, natural attenuation mechanisms originally predicted by geochemical modelling have also been confirmed by long-term trends in groundwater quality. The phased implementation of mitigation measures combined with targeted site assessment and a carefully defined Risk Management Plan with long-term monitoring have provided a cost-effective and successful solution for post-closure management of surface water and groundwater. Additional site assessment, mitigation measures and improvements to existing environmental controls will continue to be implemented on an as needed basis. Further improvements to groundwater and surface water quality are expected to be observed with planned long-term surface water and groundwater monitoring.

Reversible state changes of classical and quantum systems are shown to be represented by isometric state transformations. An operational distinction between reversible and irreversible dynamics is given and related to the geometric characterisation of the associated state transformations.

description: We have studied the evolution of the Zero-Bias Conductance Peak (ZBCP) splitting under applied magnetic fields in tunneling experiments on Y1Ba2Cu3O7-x(YBCO), and particular its hysteresis. We have been able to distinguish between two possible contributions to the splitting. One of them is connected to Meissner screening currents whose variation in increasing fields is governed by the Bean-Livingston barrier that delays flux entry well above the lower thermodynamical critical field Hc1, up to the fields of the order of the thermodynamical critical field Hc. The other contribution, dominant in (110) oriented films, is seen in decreasing fields where there are no Meissner screening currents, since there is no barrier to flux exit and it may be connected to the magnetic induction in the sample as proposed by Laughlin.

description: The behavior of water confined at the nanoscale plays a fundamental role in biological processes and technological applications, including protein folding, translocation of water across membranes, and water filtration and desalination processes. Remarkably, nanoscale confinement can drastically alter the properties of water. Understanding these changes in the physical behavior of water can provide new insights into many scientific questions and technical challenges.
      This thesis focuses on phase diagrams of water confined by graphene and graphene oxide. First, by performing Molecular Dynamic (MD) simulations, we constructed phase diagrams of water confined by graphene, a hydrophobic smooth surface. We found that the phase behaviors of water confined by graphene are complicated. In the phase diagram, monolayer square ice, bilayer square ice, liquid and vapor phases were presented. The non-monotonic cavitation pressures as a function of walls separations was unexpected. The values of cavitation pressures significantly deviated from the classical prediction for bulk water.
      Next, I moved to water under hydrophilic confinements. The first model used was a hydrophilic graphene-based surface where graphene C-water O interactions were tuned to create a hydrophilic surface but maintaining the geometry of the graphene. The phase diagram of water confined by hydrophilic graphene is presented. The extremely high magnitude of cavitation pressures found in this analysis suggests that energy can be converted efficiently from changes in relative humidity. Furthermore, the oscillation of cavitation pressures as a function of walls separations is relevant to water transportation. By randomly distributing hydroxyl groups on graphene, we saw similar cavitation pressures in a graphene oxide (GO) model.

description: We calculate the two-loop quantum corrections, including the back-reaction of the Hawking radiation, to the one-loop effective metric in a unitary gauge quantization of the CGHS model of 2d dilaton gravity. The corresponding evaporating black hole solutions are analysed, and consistent semi-classical geometries appear in the weak-coupling region of the spacetime when the width of the matter pulse is larger then the short-distance cutoff. A consistent semi-classical geometry also appears in the limit of a shock-wave matter. The Hawking radiation flux receives non-thermal corrections such that it vanishes for late times and the total radiated mass is finite. There are no static remnants for matter pulses of finite width, although a BPP type static remnant appears in the shock-wave limit. Semi-classical geometries without curvature singularities can be obtained as well. Our results indicate that higher-order loop corrections can remove the singularities encountered in the one-loop solutions.

description: Studies of lepton-flavor violation in strangeness-changing ($|ΔS|=1$) transitions have a~long tradition in the kaon sector where they provide some of the strongest limits on physics beyond the standard model. Recent hints of violation of lepton-flavor universality in $B$-meson decays have revived interest in lepton-flavor violation as the two phenomena appear simultaneously in many extensions of the standard model. At the same time, the LHCb experiment has produced new results for the hyperon process $Σ^+\to pμ^+μ^-$ and may be in a position to study other rare hyperon decay modes. With this in mind, we investigate $|ΔS|=1$ hyperon decays into different-flavor lepton pairs $e^\pmμ^\mp$ in a model-independent manner and contrast the coverage of parameter space that can be achieved with what is known from kaon modes. We include a comparison with selected two-body leptonic decays of charged mesons, with $K\to πν\barν$ modes, with $μ\to e$ conversion, and with lepton-flavor violating decays of other neutral mesons, all of which constrain the same parameter space in a complementary~way.

description: We study the spectral properties of discrete one-dimensional Schrödinger operators with Sturmian potentials. It is shown that the point spectrum is always empty. Moreover, for rotation numbers with bounded density, we establish purely $α$-continuous spectrum, uniformly for all phases. The proofs rely on the unique decomposition property of Sturmian potentials, a mass-reproduction technique based upon a Gordon-type argument, and on the Jitomirskaya-Last extension of the Gilbert-Pearson theory of subordinacy.

Perylene-Diimide Helicenes: A New Molecular Architecture for Chiral Electronics

description: Perylene-3,4,9,10-tetracarboxylic diimide (PDI) has emerged as a building block of organic materials for next generation molecular electronics. Intensely absorbing and chemically robust, PDI-based materials often excel as n-type semiconductors in organic field-effect transistors and organic photovoltaic (OPV) cells. Notably, twistacene nanoribbons arising from the iterative fusion of PDI to ethylene have been incorporated into OPV cells with power conversion efficiencies approaching 10%. These PDI-twistacenes adopt various unresolvable isoenergetic conformations in solution, precluding the possibility of optical activity.
      In pursuit of persistent helical chirality in PDI-based nanoribbons, I have prepared and now present naphthyl- and anthracenyl-linked PDI-dimer helicene (NPDH and APDH). Their syntheses entail the cross-coupling of an acene to two PDI subunits, followed by oxidative ultraviolet cyclizations. Straining the polyaromatic surface does not encumber the efficiency of these photocyclizations: they proceed quantitatively, without a trace of the sterically favored regioisomers. We have resolved NPDH and APDH into their constituent enantiomers by chiral high performance liquid chromatography. Solutions of APDH racemize at room temperature, whereas NPDH does not invert at 250 °C. The enantiostability of NPDH arises from the extensive intramolecular overlap of its π-surface. Looking down its stereogenic axis reveals ten pairs of π-bonded atoms eclipse one another. The nearest of these pairs are separated by 3.2 Å, closer than twice the van der Waals radius of the carbon atom. Thus, the naphthyl link of NPDH facilitates intramolecular π-to-π collisions between the PDI subunits. Voltammetric, spectroelectrochemical, and EPR measurements suggest these π-to-π collisions enable through-space electronic delocalization when NPDH is reduced.
      I next report the preparation of a π-helix of helicenes constituted from three PDI monomers and two naphthalene subunits. Two different synthetic routes of alternating cross-couplings and oxidative photocyclizations provided this nanoribbon, naphthyl-fused PDI-trimer helix (NP3H). Remarkably, visible light from household lightbulbs induces these cyclizations, although the final cyclization proceeds more swiftly when on the helix exterior than when within its core. NP3H possesses extraordinary chiroptical properties, exhibiting numerous and incredibly intense electronic circular dichroism (ECD) across the UV-visible range (|Δε| = 820 M-1 cm-1 at 407 nm). The ECD spectrum of NP3H transforms significantly in the presence of a mild reducing agent and visible light. Spectroelectrochemical measurements confirmed that photoinduced electron transfer to the π-helix tunes its absorbance of circularly polarized light.
Information Geometric Complexity of Entropic Motion on Curved Statistical Manifolds under Different Metrizations of Probability Spaces

description: We investigate the effect of different metrizations of probability spaces on the information geometric complexity of entropic motion on curved statistical manifolds. Specifically, we provide a comparative analysis based upon Riemannian geometric properties and entropic dynamical features of a Gaussian probability space where the two distinct dissimilarity measures between probability distributions are the Fisher-Rao information metric and the alpha-order entropy metric. In the former case, we observe an asymptotic linear temporal growth of the information geometric entropy (IGE) together with a fast convergence to the final state of the system. In the latter case, instead, we note an asymptotic logarithmic temporal growth of the IGE together with a slow convergence to the final state of the system. Finally, motivated by our findings, we provide some insights on a tradeoff between complexity and speed of convergence to the final state in our information geometric approach to problems of entropic inference.

description: In this paper, we review the construction of low-dimensional manifolds of reduced description for equations of chemical kinetics from the standpoint of the method of invariant manifold (MIM). MIM is based on a formulation of the condition of invariance as an equation, and its solution by Newton iterations. A review of existing alternative methods is extended by a thermodynamically consistent version of the method of intrinsic low-dimensional manifolds. A grid-based version of MIM is developed, and model extensions of low-dimensional dynamics are described. Generalizations to open systems are suggested. The set of methods covered makes it possible to effectively reduce description in chemical kinetics.

description: Liposome supported peritoneal dialysis is a recently described technique which may eventually be applicable in the clinical scenario of the intoxicated patient. We evaluated the hypothesis that intravenous injection of lipid emulsion (ILE) would augment acidic pH gradient liposome supported peritoneal dialysis (LSPD). Orogastrically amitriptyline dosed rats were treated with either Sodium bicarbonate (NaHCO3) intravenously and standard intraperitoneal dialysate (Group A); NaHCO3 intravenously and LSPD (Group B); or ILE and LSPD (Group C). The primary endpoint was dialysate amitriptyline concentration after a 60 min dwell. Secondary analysis included an estimate of extraction ratio for peritoneal blood flow (ERs). There were significantly higher intraperitoneal concentrations of amitriptyline and ERs in the two groups treated with LSPD (Group B, p = 0.02, Group C, p p > 0.20). LSPD increased the amitriptyline concentration in peritoneal dialysate. No further increase was demonstrated with ILE. This may be either because such an effect is absent, or type II error. Exploratory analysis suggests LSPD may be driven by total rather than free drug concentrations.

Behaviour of the Centrifugal Force and of Ellipticity for a Slowly Rotating Fluid Configuration with Different Equations of State

description: We have evaluated the centrifugal force acting on a fluid element and the ellipticity of the fluid configuration, which is slowly rotating, using the Hartle-Thorne solution for different equations of state. The centrifugal force shows a maximum in every case, whereas the reversal in sign could be seen in only one case, and the system becomes unstable in other cases. The ellipticity as calculated from the usual definition shows maxima, whereas the definition obtained from the equilibration of the inertial forces, shows a negative behaviour, indicating that the system is prolate and not oblate. This prolate shape of the configuration is similar to the one earlier found by Pfister and Braun for a rotating shell of matter, using the correct centrifugal force expression for the interior. The location of the centrifugal maxima gets farther away from the Schwarzschild radius as the equation of state gets softer.
