Deep CPTs to Characterize Mine Tailings at Pinto Valley

description: The Pinto Valley mine in Arizona utilizes upstream construction to contain tailings consisting of predominately sand and silt to a maximum height of about 172 meters (m). Characterization of the in-situ tailings to full depth is key to understanding the overall behaviour of the facility. Previous investigations of the tailings from the dam crest using conventional surface core penetration testing (CPT) to a maximum depth of around 100 m or less was limited due to the dense upper sand tailings combined with accumulated push-rod friction. To fully characterize the complete tailings profile, an innovative technique was used incorporating a combination of conventional truck-mounted surface CPT pushed to refusal, followed by a rotary drill rig using incremental wireline CPT (Raptor-CPT) to greater depths. This paper describes the incremental drilling and Raptor-CPT method that was able to achieve a final depth of 172 m, possibly the deepest onland CPT on record. Specifically, the wireline method allowed for rapid deployment of the cone down-hole without the need for push rods from the surface as the cone is latched into the bottom of the drill string. Additional benefits and testing on site included seismic measurements and the ability to take samples of the tailings for further laboratory testing. The wireline CPT borehole served a dual purpose by installing an 8- level nested set of vibrating wire piezometers for on-going monitoring.

description: Excerpts from the report: Farmers market most of their peanuts during a 2-month period following harvest and field curing. Shellers, crushers , and other dealers or handlers (including Commodity Credit Corporation) then store this crop as farmers stock for periods ranging usually from 2 to 8 months. This crop is usually stored in the areas where produced. Storage of farmers stock peanuts presents several economic problems such as excessive loss of weight and quality due to loss of moisture, kernel damage, and insects and rodents. The immediate problem is to determine the changes in quantity and quality of peanuts occurring during storage and the extent of the loss due to the various factors. This study was designed to evaluate the economic significance of changes in quantity and quality of farmers stock peanuts occurring during storage under varying conditions.
Expectation value of $\mathrm{T}\overline{\mathrm{T}}$ operator in curved spacetimes

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the expectation value of the $\mathrm{T}\overline{\mathrm{T}}$ operator in spacetimes with constant curvature. We define an diffeomorphism invariant biscalar whose coinciding limit gives the expectation value of the $\mathrm{T}\overline{\mathrm{T}}$ operator. We show that this biscalar is a constant in flat spacetime, which reproduces Zamolodchikov's result in 2004. For spacetimes with non-zero curvature, we show that this is no longer true and the expectation value of the $\mathrm{T}\overline{\mathrm{T}}$ operator depends on both the one-point and two-point functions of the stress-energy tensor.

description: We prove a conjecture of Hutchings and Lee relating the Seiberg-Witten invariants of a closed 3-manifold X with b_1 > 0 to an invariant that `counts' gradient flow lines--including closed orbits--of a circle-valued Morse function on the manifold. The proof is based on a method described by Donaldson for computing the Seiberg-Witten invariants of 3-manifolds by making use of a `topological quantum field theory,' which makes the calculation completely explicit. We also realize a version of the Seiberg-Witten invariant of X as the intersection number of a pair of totally real submanifolds of a product of vortex moduli spaces on a Riemann surface constructed from geometric data on X. The analogy with recent work of Ozsvath and Szabo suggests a generalization of a conjecture of Salamon, who has proposed a model for the Seiberg-Witten-Floer homology of X in the case that X is a mapping torus.

description: Violent intergroup conflicts are often motivated by commitments to abstract ideals such as god or nation, so-called ‘sacred’ values that are insensitive to material trade-offs. There is scant knowledge of how the brain processes costly sacrifices for such cherished causes. We studied willingness to fight and die for sacred values using fMRI in Barcelona, Spain among supporters of a radical Islamist group. We measured brain activity in radicalized individuals as they indicated their willingness to fight and die for sacred and non-sacred values, and as they reacted to peers' ratings for the same values. We observed diminished activity in dorsolateral prefrontal cortex (dlPFC), inferior frontal gyrus, and parietal cortex while conveying willingness to fight and die for sacred relative to non-sacred values—regions that have previously been implicated in calculating costs and consequences. An overlapping region of dlPFC was active when viewing conflicting ratings of sacred values from peers, to the extent participants were sensitive to peer influence, suggesting that it is possible to induce flexibility in the way people defend sacred values. Our results cohere with a view that ‘devoted actors’ motivated by an extreme commitment towards sacred values rely on distinctive neurocognitve processes that can be identified.
The Willingness of Young Engineers to Assume the Role of EOR for TSFs

Year: 2023

description: This paper presents the results of a structured questionnaire completed anonymously in June 2023 by 164 young tailings engineers to gauge their willingness to assume the role of Engineer of Record (EoR) for Tailings Storage Facilities (TSFs). Given the memory of catastrophic failures of such structures in various parts of the world over the last decade, and the implications for personal liability, the influence on young engineers has been speculated on but not quantified. This paper provides insight into the perceived barriers both real and misunderstood, that influence young engineers’ willingness to become EoRs. The barriers identified in this survey included professional liability, the demand for experience, fear of legal action, educational requirements, personal risk aversion, regulatory compliance, understanding of the EoR role, and levels of support provided by employers. Perhaps contrary to expectations, the paper finds that many young, qualified tailings engineers are willing to assume the EoR role and presents a call to the industry to address the challenges identified and to promote the development of young tailings engineers into qualified EoRs.
Surface expression of a wall fountain: application to subglacial discharge plumes

description: We use laboratory experiments and theoretical modeling to investigate the surface expression of a subglacial discharge plume, as occurs at many fjords around Greenland. The experiments consider a fountain that is released vertically into a homogeneous fluid, adjacent either to a vertical or a sloping wall, that then spreads horizontally at the free surface before sinking back to the bottom. We present a model that separates the fountain into two separate regions: a vertical fountain and a horizontal, negatively buoyant jet. The model is compared to laboratory experiments that are conducted over a range of volume fluxes, density differences, and ambient fluid depths. It is shown that the non-dimensionalised length, width, and aspect ratio of the surface expression are dependent on the Froude number, calculated at the start of the negatively buoyant jet. The model is applied to observations of the surface expression from a Greenland subglacial discharge plume. In the case where the discharge plume reaches the surface with negative buoyancy the model can be used to estimate the discharge properties at the base of the glacier.

Organisers & Speakers: Frances Madden - The British Library, Helena Cousijn - DataCite, Paolo Manghi - ISTI-CNR, Jessica Parland-von Essen - CSC, Ivo Wijnbergen. WORKSHOP ABSTRACT You are probably familiar with persistent identifiers like the DOI (digital object identifier) for publications and datasets. But do you know how they can make a researcher’s life easier? In this workshop you will explore the identifier landscape and we hope that afterwards you will engage others to use and benefit from persistent identifiers (PIDs). Persistent identifiers are at the heart of the FAIR principles and are becoming increasingly important in all research workflows.
 The organising European projects OpenAIRE, FREYA and FAIRsFAIR are all involved in strengthening the role that PIDs can play in linking researchers, research outputs, and research information. This is essential for open science, and as such PIDs are an instrument in good research practice. In this workshop you’ll hear about: Different types of PIDs such as DOIs, ORCID iDs and some emerging identifiers So-called research graphs, which make connections between research objects easy to understand, find and track; and why they aren’t perfect yet… The (new) questions PIDs and PID graphs allow you to answer How you can develop a PID policy for your institution Where to find information and training materials about PIDs As it is a workshop, we’ll move quickly from presentations to action. The attendees will discuss concrete benefits of PIDs for their community or organisation and start to design/draft an approach for how to promote PIDs. That means you’ll go home with a concrete action plan.

description: Special fibrations of toric varieties have been used by physicists, e.g. the school of Candelas, to construct dual pairs in the study of Het/F-theory duality. Motivated by this, we investigate in this paper the details of toric morphisms between toric varieties. In particular, a complete toric description of fibers - both generic and non-generic -, image, and the flattening stratification of a toric morphism are given. Two examples are provided to illustrate the discussions. We then turn to the study of the restriction of a toric morphism to a toric hypersurface. The details of this can be understood by the various restrictions of a line bundle with a section that defines the hypersurface. These general toric geometry discussions give rise to a computational scheme for the details of a toric morphism and the induced fibration of toric hypersurfaces therein. We apply this scheme to study the family of 4-dimensional elliptic Calabi-Yau toric hypersurfaces that appear in a recent work of Braun-Candelas-dlOssa-Grassi. The Maple codes that are employed for the computation are provided. Some directions for future work are listed in the end.

Thus, gravitational waves can be probed by a graviton-magnon detector which measures resonance fluorescence of magnons. Searching for gravitational waves with a wave length $λ$ by using a ferromagnetic sample with a dimension $l$, the sensitivity of the graviton-magnon detector reaches spectral densities, around $5.4 \times 10^{-22} \times (\frac{l}{λ/2π})^{-2} \ [{\rm Hz}^{-1/2}]$ at 14 GHz and $8.6 \times 10^{-21} \times (\frac{l}{λ/2π})^{-2} \ [{\rm Hz}^{-1/2}]$ at 8.2 GHz, respectively.

description: The final state interaction in DIS of leptons off a nucleus A, due to the propagation of the struck nucleon debris and its hadronization in the nuclear environment is considered. The effective cross section of such a partonic system with the nucleons of the medium and its time dependence are estimated on the basis of a model which takes into account the production of hadrons due to the breaking of the color string and to gluon radiation. It is shown that the details of the propagation of the partonic system in the nuclear environment can be thoroughly investigated by the semi-inclusive process A(e,e'(A-1))X, in which the scattered lepton is detected in coincidence with the nucleus (A-1) in low energy and momentum states. The rescattering of the struck nucleon debris with the medium damps and distorts the momentum distributions of (A-1) in a way which is very sensitive to the details of effective cross section of the debris. The total cross section of the process on ^4He, ^16O, and ^40Ca, related to the probability that after a target nucleon experiences a DIS process, the recoiling (A-1) nucleus remains intact, is evaluated, and the distorted momentum distribution of the recoiling (A-1) system is obtained. It is shown that both quantities are very sensitive to the details of the early stage of hadronization of the nucleon debris in the nuclear medium.

description: This research study is drawing upon the cultural-historical theory of Vygotsky to examine English speech development as higher mental function. English as Foreign Language teaching strategies were investigated in Saudi primary schools to find better ways of teaching English through social interaction and communication. It is important for English speech development that the present form of the student interacts with a developed form of English speech in English activities which moves forward the process of development. The teacher can create conditions for English speech development and understand the students' level of English speech then engage them in several social situations. This study declares that there is an interrelated relationship between the processes of English language acquisition and English speech development.

description: Conformal surface parameterization is useful in graphics, imaging and visualization, with applications to texture mapping, atlas construction, registration, remeshing and so on. With the increasing capability in scanning and storing data, dense 3D surface meshes are common nowadays. While meshes with higher resolution better resemble smooth surfaces, they pose computational difficulties for the existing parameterization algorithms. In this work, we propose a novel parallelizable algorithm for computing the global conformal parameterization of simply-connected surfaces via partial welding maps. A given simply-connected surface is first partitioned into smaller subdomains. The local conformal parameterizations of all subdomains are then computed in parallel. The boundaries of the parameterized subdomains are subsequently integrated consistently using a novel technique called partial welding, which is developed based on conformal welding theory. Finally, by solving the Laplace equation for each subdomain using the updated boundary conditions, we obtain a global conformal parameterization of the given surface, with bijectivity guaranteed by quasi-conformal theory. By including additional shape constraints, our method can be easily extended to achieve disk conformal parameterization for simply-connected open surfaces and spherical conformal parameterization for genus-0 closed surfaces. Experimental results are presented to demonstrate the effectiveness of our proposed algorithm. When compared to the state-of-the-art conformal parameterization methods, our method achieves a significant improvement in both computational time and accuracy.

description: In this paper we deal with singular varieties of bounded mean curvature in the viscosity sense. They contain all varifolds of bounded generalized mean curvature. In the first part we investigate the second-order properties of these varieties, obtaining results that are new also in the varifold's setting. In particular we prove that the generalized normal bundle of these varieties satisfies a natural Lusin (N) condition, which allows to extend the classical Coarea formula for the Gauss map of smooth varieties, and to introduce for all integral varifolds of bounded mean curvature a natural definition of second fundamental form, whose trace equals the generalized varifold mean curvature. In the second part, we use this machinery to extend a sharp geometric inequality of Almgren to all compact varieties of bounded mean curvature in the viscosity sense and we characterize the equality case. As a consequence we formulate sufficient conditions to conclude that the area-blow-up set is empty for sequences of varifolds whose first variation is controlled.

title: The Contextualization of Myth: Identification of Myth in the Propagation of Narrative Across Generational Boundaries
Creators: name: Ponthieux, Joseph G.
Publisher: name: Old Dominion University Libraries
Year: 2021

description: This thesis demonstrates the unique correlation between myth and the propagation of narrative across generational boundaries. It argues that myth occurs in the intersection of belief, semiotics, and context, and further enables a way of re-encoding a narrative with a dual contextuality. This dual context preserves a narrative’s literal context while endowing it with a new or modified myth context and affords the audience a selection of choices for how to receive a narrative experienced as myth. To demonstrate this correlation a Myth Context Reception Model is designed for the purpose of identifying ascendent, obscure or emergent myths evident in an audience’s reception of narrative, as a result the paradoxical human beliefs and behaviors the audience imposes upon narratives appropriated as myth. Three over-arching narratives, classical myth, Santa Claus, and Batman are then evaluated as exemplars, using the procedures defined by the model, to demonstrate that myth can influence the propagation of a narrative across many generations and in ways we might not expect. And to show that myth is a powerful a rhetoric that is stealthily obscure, remarkably ubiquitous, and resilient. Even in the modern day.

description: In two dimensions, non-trivial topology and enhanced correlation lead to amazing physical phenomena. Graphene offers a high-quality, ultra-tunable and integratable two dimensional electron system in the study of interacting and topological quantum fluids. In this thesis we studied in detail various emergent quantum phenomena of electron fluids due to both strong in-plane and out-of-plane interaction between electrons in single and multi-layer graphene systems. Using magnetoresistance measurement in the corbino disk geometry, we manged to quantitatively measure the viscosity of electrons in monolayer and bilayer graphene as a function of carrier density and temperature. We demonstrated a crossover between degenerate Fermi liquid and non-degenerate electron-hole liquid. In the quantum Hall regime, we applied the corbino geometry as a probe of the incompressible sample bulk, improving significantly the resolution of fragile quantum Hall states compared to Hall bar devices. The improved resolution enables quantitative studies over a much broader parameter space in both singlelayer and multi-layer graphene system. In double-layer graphene where two vertically stacked graphene layers are in close proximity but electrically separated by a thin hBN tunnel barrier, we observed sequence of FQHS which can be perfectly described by two-component composite fermion theory. Using a combination of different measurement configuration, we found evidence for a novel type of two-component non-abelian FQHS. At \nu = 1 in double-layer graphene where ground states of indirect excitons occur, we mappped out the entire phase diagram. We realized BEC-BCS crossover in the exciton condensation phase tunable with both magnetic field and electrostatic gating. At small exciton filling fraction, we discovered Wigner crystal of excitons. Lastly, we realized a strongly correlated triple-layer quantum Hall system with independent control of carrier density in each layer and demonstrated three-layer coherent quantum Hall effect at total integer filling fraction and possibly fractional filling fraction.

description: P/Q-type voltage-gated calcium channels (CaV2.1) are expressed in both central and peripheral nervous systems, where they play a critical role in neurotransmitter release. Mutations in the pore-forming α1 subunit of CaV2.1 can cause neurological disorders such as episodic ataxia type 2, familial hemiplegic migraine type 1 and spinocerebellar ataxia type 6. Interestingly, a 190-kDa fragment of CaV2.1 was found in mouse brain tissue and cultured mouse cortical neurons, but not in heterologous systems expressing full-length CaV2.1. In the brain, the 190-kDa species is the predominant form of CaV2.1, while in cultured cortical neurons the amount of the 190-kDa species is comparable to that of the full-length channel. The 190-kDa fragment contains part of the II-III loop, repeat III, repeat IV and the C-terminal tail. A putative complementary fragment of 80-90 kDa was found along with the 190-kDa form. Moreover, preliminary data show that the abundance of the 190-kDa species and the 80-90-kDa species relative to the full-length channel is upregulated by increased intracellular Ca²⁺ concentration.
      Truncation mutations in the P/Q-type calcium channel have been found to cause the neurological disease episodic ataxia type 2. Some of the disease-causing truncations resemble the 190-kDa truncated channel that we found. Three pairs of truncated versions of CaV2.1 were engineered to resemble putative products of proteolytic cleavage in the three intracellular loops. Electrophysiological properties of these truncated channels were studied. The truncated channel corresponding to the N-terminal fragment produced by cleavage in the II-III loop has a suppressive effect on full-length P/Q channel currents, resembling the effects of several truncation mutants that cause episodic ataxia type 2. The complementary pair of truncated channels created by a truncation site in the I-II loop forms a functional channel when coexpressed. These results shed light on the functional effects of proteolytic cleavage in the intracellular loops of the P/Q channel.

description: In the conventional adiabatic regularization the vacuum ultraviolet divergences of a quantum field in curved spacetime are removed by subtracting the $k$-mode of the stress tensor to the 4th-order. For a scalar field in de Sitter space, we find that the 4th-order regularized spectral energy density is negative. Moreover, the 2nd-order regularization for minimal coupling ($ξ=0$) and the 0th-order regularization for conformal coupling ($ξ=\frac16$) yield a positive and UV-convergent spectral energy density and power spectrum. The regularized stress tensor in the vacuum is maximally symmetric and can drive inflation, while its $k$-modes representing the primordial fluctuations are nonuniformly distributed. Conventional regularization of a Green's function in position space is generally plagued by a log IR divergence. Only in the massless case with $ξ=0$ or $\frac16$, we can directly regularize the Green's functions and obtain vanishing results that agree with the adiabatic regularization results. In this case, the regularized power spectrum and stress tensor are both zero, and no trace anomaly exists. To overcome the log IR divergence problem in the massive cases with $ξ=0$ and $\frac16$, we perform Fourier transformation of the regularized power spectra and obtain the regularized analytical Green's functions which are IR- and UV-convergent.

description: The new complex materials have wide applications in next generation technologies in industrial fields such as electronics, energy production, environment engineering, etc. Understanding their structure is the key in keeping developing new materials and improving their performance. As they are more and more complex in different length scale, new methods that utilize information from different sources and be able to provide complex structural information are on the horizon of this new era.
      In this thesis, we developed new methods that process the mixed data and provide the extra information that people are interested in. First one is extending the computed tomography technique with other analysis method including texture analysis and Pair Distribution Function (PDF) method. The new methods enable us to study the coupling of desired structural properties, such as texture and local local structure of nano-particles, at meso-scale. For example, by applying the texture-CT analysis on the LiCoO₂ coin cell, we found the texture of LiCoO₂ particles was quite inhomogeneous. By combining PDF and CT method, we successfully studied the catalyst reaction and the participle size distribution in industrial catalyst. Second one is a new method of obtaining reliable anomalous differential Pair Distribution Function (adPDF) by using diffraction data sets in wide energy range and an ad-hoc algorithm that perform the data correction automatically. The new method was demonstrated using both simulated data and real experimental data.

description: Recently the background independent nonperturbative quantization technique has been extended to theories of gravity and the corresponding quantum effective cosmology has been derived, which provides us with necessary avenue to explore the pre-inflationary dynamics. Brans-Dicke loop quantum cosmology (BDLQC) is one such theory whose effective background dynamics is considered in this article. Starting with a quantum bounce, we explore the pre-inflationary dynamics of a universe sourced by a scalar field with the Starobinsky potential in BDLQC. Our study is based on the idea that though Einstein's and Jordan's frames are classically equivalent up to a conformal transformation in Brans-Dick theory, it is not true after quantization. Taking the Jordan frame as the physical one we explore in detail the bouncing scenario which is followed by a phase of slow roll inflation. The three phases of the evolution of the universe namely, bouncing, transition from quantum bounce to classical universe and the slow roll inflation, are noted for an initially kinetic energy dominated bounce. In addition, to be consistent with observational data, we also find out the allowed data space of initial conditions that would produce 60 e-folds of expansion during the slow roll inflation.

description: This work explores the potential of deformation assessment in assessing the performance of a tailings storage facility (TSF) during construction and operation. The studied TSF has a maximum height of 35 m from toe to crest. It was constructed in four stages, beginning with a 20 m-high starter dam, followed by three 5-m-upstream raises. Shortly after the construction of the first raise was completed, surface cracking was observed at the crest of the starter dam and downstream slope. After the cracks were detected, additional instrumentation was installed to monitor displacements and crack progression within the TSF during the operation and construction of the following three raises. To provide confirmation of the conceptual explanation for the observed cracking and deformation pattern, a series of numerical simulations were completed using a two-dimensional finite element software. Initially, a simplified model with fewer variables was developed to provide a qualitative understanding of the physical phenomenon. Later, a detailed analysis was conducted with the aim of reproducing the recorded displacements quantitatively. This paper summarizes the results of these simulations and their comparison with field observations and monitoring.

description: The mating of budding yeast depends on chemotropism, a fundamental cellular process. The two yeast mating types secrete peptide pheromones that bind to GPCRs on cells of the opposite type. Cells find and contact a partner by determining the direction of the pheromone source and polarizing their growth toward it. Actin-directed secretion to the chemotropic growth site (CS) generates a mating projection. When pheromone-stimulated cells are unable to sense a gradient, they form mating projections where they would have budded in the next cell cycle, at a position called the default polarity site (DS). Numerous models have been proposed to explain yeast gradient sensing, but none address how cells reliably switch from the intrinsically determined DS to the gradient-aligned CS, despite a weak spatial signal. Here we demonstrate that, in mating cells, the initially uniform receptor and G protein first polarize to the DS, then redistribute along the plasma membrane until they reach the CS. Our data indicate that signaling, polarity, and trafficking proteins localize to the DS during assembly of what we call the gradient tracking machine (GTM). Differential activation of the receptor triggers feedback mechanisms that bias exocytosis upgradient and endocytosis downgradient, thus enabling redistribution of the GTM toward the pheromone source. The GTM stabilizes when the receptor peak centers at the CS and the endocytic machinery surrounds it. A computational model simulates GTM tracking and stabilization and correctly predicts that its assembly at a single site contributes to mating fidelity.

description: Reconnection processes of twin-chains are systematically studied in the quadratic twist map. By using the reversibility and symmetry of the mapping, the location of the indicator points is theoretically determined in the phase space. The indicator points enable us to obtain useful information about the reconnection processes and the transition to global chaos. We succeed in deriving the general conditions for the reconnection thresholds. In addition, a new type of reconnection process which generates shearless curves is studied.
