Muon Radiography as a Novel Tool to Characterize Tailing Storage Facilities

description: We report on the potential of the muon density radiography technique for the in-situ characterization and digital mapping of the distribution of unit weights within tailingsstorage facilities (TSF). Muon radiography or muography is a well-established technique for measuring the bulk density of dense objects across large scales. As with other more conventional nuclear inspection methods, muography is robust, direct, and quantitative. However, in place of the radio-nuclide sources or X-ray tubes used in conventional medical or industrial X-ray applications, muon radiography utilizes the naturally occurring flux of so-called secondary cosmic ray particles (aka muons) originating in the earth’s atmosphere. This background radiation source is not only free and intrinsically safe, but also well-characterized and continuously available everywhere on earth. Muon particles are also highly penetrating and maintain excellent directionality even in the subsurface. This allows muographers to analyze and map the interior of large, dense structures and provide in-situ volumetric density data in a minimally invasive way without the disadvantages of using a dangerous nuclear logging source. In this paper we will show results from high fidelity, fully 3D, nuclear transport calculations to simulate the response and sensitivity of muon radiography sensors placed at different locations, including pre-existing slim boreholes, within an upstream tailings dam. We will compare typical trade-offs between measurement precision, spatial resolution, and measurement time, as a function of different installation set ups, and focus on the practical and urgent issue of quantifying groundwater content and characterizing the location of phreatic surfaces over a dense 3D data grid within a tailings dam. We believe that muography can provide a unique and powerful tool for geophysical characterization of actively managing geotechnical risk in tailing storage facilities, provided that practical installation choices in either existing or ad-hoc boreholes can be made.

Influence of the Suspension Chemical Property on the Differential Settling Behaviour of Copper Tailings Suspension
Creators: name: Li, Yuan

name: Van Zyl, Dirk J. A.
Publisher: name: The University of British Columbia
Year: 2024

description: This paper presents a comprehensive investigation into the differential settling of a copper tailings suspension under varying pH conditions. Batch settling tests and interruptive settling tests were conducted to analyze settling velocities, solids content profiles, and particle size distributions (PSDs) along the settling direction. The results of the conventional batch settling tests revealed that increasing the pH of the suspension influenced the settling velocity of fine particle species contained in the suspension. Solids content profiles and the PSD profiles provided insights into the differential settling behaviour of the suspension. Coarse particles settled at higher velocities, accumulating at the bottom, resulting in higher solids content and larger PSDs in the sediment. The study established a clear link between the suspension’s pH condition and differential settling behaviour. The discussion showed that increasing the pH value enhanced the aggregation degree of the copper tailing suspension, leading to the result that the difference in settling velocities among particle species was reduced, and the segregation of coarse particles was suppressed. Future research should focus on the detailed influence of the pH condition on the settling velocities of coarse particle species, which can be achieved by performing force balance analyses on coarse particle species.

description: We show that in the case of the BFKL pomeron with running coupling the diffusion pattern is strongly modified and is characterised by the sudden tunneling transition to the non-perturbative regime. We suggest that by using the b - expansion method one can suppress the non-perturbative Pomeron and isolate purely perturbative part of the gluon Green's function.

description: This paper targets to juxtapose the points of view of citizens, as be-neficiaries of the European programmes – on the one hand, and of practitio-ners – as designers and experts in charge of implementing the Cohesion Policy programmes – on the other. The study was conducted at the level of a sample consisting of 9 NUTS II regions of the European Union, which were selected to be representative for the com-plex and heterogeneous reality of the EU Cohesion Policy. The analysis of data collected from the case study regions demonstrated that, regardless of the status of the regions (competitiveness or convergence regions), there are overlaps as regards points of view of the two categories of regional actors only for a part of regional priorities. At the same time, the study revealed that the citizens’ trust in the effectiveness of the EU in targeting regional issues is higher in the case of those regional needs that are on the agenda of both categories of regional actors and it drops for those regional issues for which perceptive divergences exist between citizens and practitioners.

description: We analyze the consistency of electroweak breaking within the simplest high-scale Standard Model type-I seesaw mechanism. We derive the full two-loop RGEs of the relevant parameters, including the quartic Higgs self-coupling of the Standard Model. For the simplest case of bare "right-handed" neutrino mass terms we find that, with large Yukawa couplings, the Higgs quartic self-coupling becomes negative much below the seesaw scale, so that the model may be inconsistent even as an effective theory. We show, however, that the "dynamical" type-I high-scale seesaw with spontaneous lepton number violation has better stability properties.

description: These lectures present a survey of recent developments in the area of random matrices (finite and infinite) and random permutations. These probabilistic problems suggest matrix integrals (or Fredholm determinants), which arise very naturally as integrals over the tangent space to symmetric spaces, as integrals over groups and finally as integrals over symmetric spaces. An important part of these lectures is devoted to showing that these matrix integrals, upon apropriately adding time-parameters, are natural tau-functions for integrable lattices, like the Toda, Pfaff and Toeplitz lattices, but also for integrable PDE's, like the KdV equation. These matrix integrals or Fredholm determinants also satisfy Virasoro constraints, which combined with the integrable equations lead to (partial) differential equations for the original probabilities.

description: For many Latino immigrant children the transition from adolescence to adulthood and more specifically from high school to college or the workforce can be a daunting experience. Scholars have identified contextual factors such as family, culture, and access to academic and financial resources contribute significantly to the academic and career decision making of Latino immigrant youths (Chaves et al., 2004). Vocational psychology research literature has been criticized for the exclusion of diverse populations, particularly inner city youth (Medvide & Blustein, 2010) from career development theories. Using consensual qualitative research (CQR), the current study broadens the understanding of the career development of Latino immigrant youth by gathering 15 participant narratives from current NYC high school students. These interviews were audio recorded, transcribed, and analyzed using CQR methods (Hill, Knox, Thompson, Williams, Hess, & Ladany, 2005). The results of the study illustrate how culture, family support, access to financial and academic resources, and perceived barriers impact the career decision-making of Latino immigrant youth. More specifically, results indicate Latino immigrant youth highly value family relationships and teacher support in their career decision-making, and feel these supports are essential for their career success. Additionally, participants’ internalization of their social status and access to financial and academic resources critically influence their career decisions. Recommendations for research and clinical practice were presented with an emphasis on expanding multicultural competency and culturally responsive counseling interventions provided to students and families in order to reinforce students’ academic, social, and cultural strengths.
Automatic Kalman-Filter-based Wavelet Shrinkage Denoising of 1D Stellar Spectra

description: We propose a non-parametric method to denoise 1D stellar spectra based on wavelet shrinkage followed by adaptive Kalman thresholding. Wavelet shrinkage denoising involves applying the Discrete Wavelet Transform (DWT) to the input signal, `shrinking' certain frequency components in the transform domain, and then applying inverse DWT to the reduced components. The performance of this procedure is influenced by the choice of base wavelet, the number of decomposition levels, and the thresholding function. Typically, these parameters are chosen by `trial and error', which can be strongly dependent on the properties of the data being denoised. We here introduce an adaptive Kalman-filter-based thresholding method that eliminates the need for choosing the number of decomposition levels. We use the `Haar' wavelet basis, which we found to be the best-suited for 1D stellar spectra. We introduce various levels of Poisson noise into synthetic PHOENIX spectra, and test the performance of several common denoising methods against our own. It proves superior in terms of noise suppression and peak shape preservation. We expect it may also be of use in automatically and accurately filtering low signal-to-noise galaxy and quasar spectra obtained from surveys such as SDSS, Gaia, LSST, PESSTO, VANDELS, LEGA-C, and DESI.

description: This study describes the employment patterns and work-to-retirement transitions of New Zealanders who were who were born between 1 April 1936 and 31 March 1940 and aged in their 60s during the 1999–2007 period, using longitudinal data from the Linked Employer-Employee Dataset. The study has two main parts. The first part provides an overview of the employment rates and income support patterns of the study population, identifying the main changes that occurred with increasing age, for men and women and for different birth cohorts. This is designed to provide general insights into the employment activity of New Zealanders aged in their 60s, using a data source that has different strengths from the data sources previously available. The second part describes the employment patterns and transitions of the study population. This section is intended to shed light on the types of employment pattern that were ‘typical’ of workers aged in their 60s during 1999-2007. It gives particular attention to the question of whether traditional or phased transitions from work to retirement were more common. The employment rate of the study population declined gradually with each month and year of age, from 60 to 69. There was a sharper fall in the employment rate at 65 years, due to a greater number of people leaving work at this age. The aggregate wage employment rate of men fell by 3.1 percentage points at 65 years, while that of women fell by 1.7 percentage points. Overall, most people did not stop working at their 65th birthday: rather, they stopped working at a wide range of ages. The employment patterns and work histories of study population members were diverse. The majority made at least one transition out of employment prior to their final exit. Among those who continued to work into their mid to late 60s, part-year and parttime employment became increasingly common. Phased transitions from work to retirement were more common than ‘traditional’ retirements involving a single and permanent transition from full-time employment to inactivity.

description: Backaction-evading measurements of mechanical motion can achieve precision below the zero-point uncertainty and quantum squeezing, which makes them a resource for quantum metrology and quantum information processing. We provide an exact expression for the conditional state of an optomechanical system in a two-tone backaction-evading measurement beyond the standard adiabatic approximation and perform extensive numerical simulations to go beyond the usual rotating-wave approximation. We predict the simultaneous presence of conditional mechanical squeezing, intra-cavity squeezing, and optomechanical entanglement. We further apply an analogous analysis to the multimode optomechanical system of two mechanical and one cavity mode and find conditional mechanical Einstein-Podolski-Rosen entanglement and genuinely tripartite optomechanical entanglement. Our analysis is of direct relevance for state-of-the-art optomechanical experiments that have entered the backaction-dominated regime.

description: An explicit isomorphism between the $R$-matrix and Drinfeld presentations of the quantum affine algebra in type $A$ was given by Ding and I. Frenkel (1993). We show that this result can be extended to types $B$, $C$ and $D$ and give a detailed construction for type $C$ in this paper. In all classical types the Gauss decomposition of the generator matrix in the $R$-matrix presentation yields the Drinfeld generators. To prove that the resulting map is an isomorphism we follow the work of E. Frenkel and Mukhin (2002) in type $A$ and employ the universal $R$-matrix to construct the inverse map. A key role in our construction is played by a homomorphism theorem which relates the quantum affine algebra of rank $n-1$ in the $R$-matrix presentation with a subalgebra of the corresponding algebra of rank $n$ of the same type.

description: We use data derived from the Longitudinal Business Database (LBD) to analyse the currency denomination and hedging behaviour of New Zealand merchandise exporters. For instance: In which currencies are New Zealand merchandise exports by country of destination denominated? Do different types of firms (e.g. by size or sector) display different hedging practices? Does the ‘cost’ of hedging (forward points) make any difference to hedging decisions? Is hedging consistent over the exchange rate cycle or do (some) exporters selectively hedge when the exchange rate reaches historical extremes? Has selective hedging been a profitable strategy for New Zealand exporters? Our results have implications for the capability of exporters to handle exchange rate volatility and for the potential impact of exchange rate volatility on exports.
Spherical neutron star collapse toward a black hole in tensor-scalar theory of gravity

description: Complete tensor-scalar and hydrodynamic equations are presented and integrated, for a self-gravitating perfect fluid. The initial conditions describe unstable-equilibrium neutron star configuration, with a polytropic equation of state. They are necessary in order to follow the gravitational collapse (including full hydrodynamics) of this star toward a black hole and to study the resulting scalar gravitational wave. The amplitude of this wave, as well as the radiated energy dramatically increase above some critical value of the parameter of the coupling function, due to the spontaneous scalarization, an effect not present in Brans-Dicke theory. In most cases, the pressure of the collapsing fluid does not have a significant impact on the resulting signal. These kind of sources are not likely to be observed by future laser interferometric detectors (such as VIRGO or LIGO) of gravitational waves, if they are located at more than a few 100 kpc. However, spontaneous scalarization could be constrained if such a gravitational collapse is detected by its quadrupolar gravitational signal, since this latter is quite lower than the monopolar one.

description: The system of $N$ classical particles on the line with the Weierstrass $\wp$ function as potential is known to be completely integrable. Recently D'Hoker and Phong found a beautiful parameterization by the polynomial of degree $N$ of the space of Riemann surfaces associated with this system. In the trigonometric limit of the elliptic potential these Riemann surfaces degenerate into rational curves. The D'Hoker-Phong polynomial in the limit describes the intersection points of the rational curves. We found an explicit determinant representation of the polynomial in the trigonometric case. We consider applications of this result to the theory of Toeplitz determinants and to geometry of the spectral curves. We also prove our earlier conjecture on the asymptotic behavior of the ratio of two symplectic volumes when the number of particles tends to infinity.

description: How do exporting firms manage currency exposures? We examine this issue at the firm level using comprehensive data from the prototype Longitudinal Business Database recently developed by Statistics New Zealand. We use these data to test both optimal and selective hedging theories. Optimal hedging theory hypothesises that firms hedging choices depend on the probability and cost of financial distress, underinvestment risks, scale, managerial risk aversion, information asymmetry, governance, ownership structures and tax rules. Recent literature suggests that some firms vary hedging positions relative to their optimal position in a selective attempt to beat the market . We examine whether hedging behaviour is consistent with hypotheses derived from optimal hedging theories, and test whether hedging positions change (possibly sub-optimally) when the NZD/AUD is perceived to be high or low relative to an historical average. Optimal and selective hedging theories are both supported by the data. Estimation is over July 2000 to March 2007 (monthly) a period during which the NZD/AUD varied substantially, making this a particularly pertinent period to test exporters currency risk management practices.
Jet Quenching in High Energy Heavy Ion Collisions by QCD Synchrotron-like Radiation

description: We consider synchrotron-like radiation in QCD by generalizing Schwinger's treatment of quantum synchrotron radiation in QED to the case of a constant chromomagnetic field. We suggest a novel mechanism for {\em jet quenching} in heavy ion collisions, whereby high-$p_t$ partons get depleted through strong (classical) color fields. The latters are encountered in the color glass condensate or in the form of expanding shells of exploding sphalerons. Unlike bremsstrahlung radiation through multiple soft rescattering, synchrotron radiation converts a jet into a wide shower of soft gluons. We estimate the energy loss through this mechanism and suggest that it contributes significantly to the unexpectedly strong jet quenching observed at RHIC.

description: A technique using layered wavelength shifting, scintillating and non-scintillating films is presented to achieve discrimination of surface $α$ events from low-energy nuclear recoils in liquid argon detectors. A discrimination power greater than $10^{8}$, similar to the discrimination possible for electronic recoils in argon, can be achieved by adding a 50 micron layer of scintillator with a suitably slow decay time, approximately 300 ns or greater, to a wavelength-shifter coated surface. The technique would allow suppression of surface $α$ events in a very large next-generation argon dark matter experiment (with hundreds of square meters of surface area) without the requirement for position reconstruction, thus allowing utilization of more of the instrumented mass in the dark matter search. The technique could also be used to suppress surface backgrounds in compact argon detectors of low-energy nuclear recoils, for example in measurements of coherent neutrino-nucleus scattering or for sensitive measurements of neutron fluxes.

description: [Introduction] Trumpets made of horns and hands cupped around the ear served to amplify sound since the days of hunter gatherers – a precursor to hearing aids of sorts. These devices remained fairly unchanged in principle until the 19th century. Today, hearing aids are much more than devices that simply amplify sound. Today’s hearing aids are complex instruments that combine amplification with cutting edge signal processing to enhance speech, reduce noise, cancel feedback, analyze acoustic environments, and link back to various IoT devices at home. Today, we enjoy miniaturization of electronics ranging from cell phones to pocket speakers. Miniaturization of electronics as we witness today can be attributed to several historical events such as the development of transistors (Mudry, 6) and World War II (Misa, 253). This paper will connect the history of electronics miniaturization and the development of hearing aid technology to argue that there was an inseparable bidirectional relationship between the two domains.
The Catalytic Efficiency and Conformational Dynamics of Escherichia coli DNA Repair Enzyme AlkB

description: Enzymes catalyze specific reactions in almost all cellular processes, including DNA replication and repair, transcription, translation, signal transduction and energy production. Therefore, extensive efforts are underway to understand the functions and mechanisms of these processes. The potential contribution of the conformational dynamics of enzymes to their high catalytic power has received particular attention in the last decades. Studies indicate that protein dynamics are involved in substrate binding and product release; however, the role of dynamics in catalysis is still controversial. Here, we investigate the substrate-dependent dynamic properties of the Escherichia coli AlkB protein, and the role of a specific dynamic transition in the efficiency of the catalytic reaction cycle. AlkB is an iron/2-oxoglutarate (Fe(II)/2OG) dependent dioxygenase, which removes certain cytotoxic alkyl lesions from DNA and RNA bases that are not repaired by other known mechanisms. Using Fe(II) as a cofactor and 2OG and molecular oxygen as co-substrates, AlkB catalyzes a multistep redox reaction in which first, 2OG is oxidized yielding succinate, carbon dioxide and a reactive oxyferryl (Fe(IV)=O) intermediate; second, the alkylated base is hydroxylated by the Fe(IV)=O intermediate, and third, the hydroxylated base spontaneously resolves upon release from the enzyme. Our fluorescence and NMR spectroscopic data demonstrate that a microsecond-tomillisecond timescale conformational transition in the nucleotide recognition lid (NRL) of AlkB regulates the correct sequential order of substrate binding, i.e. Fe(II) and 2OG first, followed by the DNA substrate. By combining isothermal titration calorimetry with NMR, we show that less than 20% of the residues in AlkB become ordered during this conformational transition, indicating that this conformational change is mostly localized to the NRL, while the conformation of the dioxygenase core is minimally altered. In mutant AlkB variants that perturb the dynamics of this transition, 2OG is oxidized generating the Fe(IV)=O intermediate; however, the reaction cycle cannot be completed due to the premature release of the alkylated DNA substrate, leading to uncoupled turnover of 2OG. These data demonstrate that the conformational dynamics control the catalytic efficiency of AlkB. Our results further extend the view on the role of protein dynamics in substrate binding or product release by emphasizing the importance of protein dynamics for coupling sequential sub-reactions in a complex multistep reaction cycle. This finding illustrates a striking example of the relation between protein dynamics and overall enzyme efficiency.

description: Measures of node centrality that describe the importance of a node within a network are crucial for understanding the behavior of social networks and graphs. In this paper, we address the problems of distributed estimation and control of node centrality in undirected graphs with asymmetric weight values. In particular, we focus our attention on $α$-centrality, which can be seen as a generalization of eigenvector centrality. In this setting, we first consider a distributed protocol where agents compute their $α$-centrality, focusing on the convergence properties of the method; then, we combine the estimation method with a consensus algorithm to achieve a consensus value weighted by the influence of each node in the network. Finally, we formulate an $α$-centrality control problem which is naturally decoupled and, thus, suitable for a distributed setting and we apply this formulation to protect the most valuable nodes in a network against a targeted attack, by making every node in the network equally important in terms of α-centrality. Simulations results are provided to corroborate the theoretical findings.

description: Given a bounded valence, bushy tree T, we prove that any cobounded quasi-action of a group G on T is quasiconjugate to an action of G on another bounded valence, bushy tree T'. This theorem has many applications: quasi-isometric rigidity for fundamental groups of finite, bushy graphs of coarse PD(n) groups for each fixed n; a generalization to actions on Cantor sets of Sullivan's Theorem about uniformly quasiconformal actions on the 2-sphere; and a characterization of locally compact topological groups which contain a virtually free group as a cocompact lattice. Finally, we give the first examples of two finitely generated groups which are quasi-isometric and yet which cannot act on the same proper geodesic metric space, properly discontinuously and cocompactly by isometries.

description: Since 1988, LaRonde Gold Mine (LaRonde) has exploited a polymetallic orebody in Quebec, Canada. Slurry tailings are deposited in two tailings storage facilities (TSF) named “Main TSF” and “Extension A4.” At the end of 2022, Main TSF and Extension A4 TSF reached their full storage capacity with slurry tailings deposition. In order to reduce the risks related to the slurry tailings management, LaRonde decided to transition to filtered tailings deposition in October 2022. This is an emerging technology that has been gaining in popularity over the past few years. A new filtered tailings stack with 12 million tons capacity is to be constructed over the existing Extension A4 TSF. The transition to filtered tailings required the commissioning of a filtration plant and the construction of a new water pond. To enable the construction of the filtered tailings stack, it was necessary to place a waste rock platform (bridgelift) over the slurry tailings stored within Extension A4. This paper describes the geotechnical investigations of the foundation soils and the slurry tailings carried out at Extension A4 TSF to support the design of the filtered tailings stack, and the construction, monitoring, and surveillance program implemented as of March 1st, 2023. The paper also discusses the results of large-scale field loading tests completed to verify and inform the design of the filtered tailings stack.
