description: Semiconductor manufacturing is on the cusp of a revolution: the Internet of Things (IoT). With IoT we can connect all the equipment and feed information back to the factory so that quality issues can be detected. In this situation, more and more edge devices are used in wafer inspection equipment. This edge device must have the ability to quickly detect defects. Therefore, how to develop a high-efficiency architecture for automatic defect classification to be suitable for edge devices is the primary task. In this paper, we present a novel architecture that can perform defect classification in a more efficient way. The first function is self-proliferation, using a series of linear transformations to generate more feature maps at a cheaper cost. The second function is self-attention, capturing the long-range dependencies of feature map by the channel-wise and spatial-wise attention mechanism. We named this method as self-proliferation-and-attention neural network. This method has been successfully applied to various defect pattern classification tasks. Compared with other latest methods, SP&A-Net has higher accuracy and lower computation cost in many defect inspection tasks.

Cost Uniqueness: An Alternative Lens for Examining Cost Behavior

subject: Firm Value
subject: Accounting

description: Cost information is a critical input required for profit analysis, earnings estimation, and firm valuation by capital market participants (Banker and Chen 2006; Weiss 2010; Ciftci et al. 2016). Conventional methods of understanding cost behavior seek to separate costs based on their movements relative to production volume. In a set of three essays, I investigate an alternative lens for examining cost behavior. In my approach, I seek to separate cost movements driven by firm-specific factors from movements that are common to industry or market peers. I refer to this as “cost uniqueness”. In the first of my essays, I describe this new construct of cost uniqueness, and I identify a method to empirically measure this new construct. Firm-specific cost variations are of special interest because costs reflect the inner workings of the firm that are opaque to investors. To establish the importance of measuring cost uniqueness, I investigate the effects of cost uniqueness on information uncertainty for external users by looking at the forecasting difficulty faced by financial analysts. In my second essay, I conduct an exploratory investigation into the forces that potentially drive some firms to be more unique than others. I organize my search around three distinct forces that can shape costs, namely, internal firm characteristics, external environment, and manager-specific characteristics. Within these three dimensions, I specifically examine various factors pertaining to the incentives and capabilities of firms to operate distinctively from their peers. In my third essay, I delve into some of the implications of cost uniqueness for firms. I examine the relationship between cost uniqueness and firm value to assess whether cost uniqueness is driven by managers’ value-enhancing activities or by value-destroying activities. I also investigate what measures a firm can take to mitigate the information uncertainty associated with cost uniqueness. Specifically, I examine whether firms increase their disclosure of cost items to help outsiders unpack cost uniqueness.

description: We propose ClipFace, a novel self-supervised approach for text-guided editing of textured 3D morphable model of faces. Specifically, we employ user-friendly language prompts to enable control of the expressions as well as appearance of 3D faces. We leverage the geometric expressiveness of 3D morphable models, which inherently possess limited controllability and texture expressivity, and develop a self-supervised generative model to jointly synthesize expressive, textured, and articulated faces in 3D. We enable high-quality texture generation for 3D faces by adversarial self-supervised training, guided by differentiable rendering against collections of real RGB images. Controllable editing and manipulation are given by language prompts to adapt texture and expression of the 3D morphable model. To this end, we propose a neural network that predicts both texture and expression latent codes of the morphable model. Our model is trained in a self-supervised fashion by exploiting differentiable rendering and losses based on a pre-trained CLIP model. Once trained, our model jointly predicts face textures in UV-space, along with expression parameters to capture both geometry and texture changes in facial expressions in a single forward pass. We further show the applicability of our method to generate temporally changing textures for a given animation sequence.

description: Recently, the LHAASO collaboration has observed the gamma rays of energies up to ten TeV from the gamma-ray burst GRB221009A, which has stimulated the community of astronomy, particle physics and astrophysics to propose various possible interpretations. In this paper, we put forward a viable scenario that neutrinos are produced together with TeV photons in the gamma-ray burst and gradually decay into the axion-like particles, which are then converted into gamma rays in the galactic magnetic fields. In such a scenario, the tension between previous axion-like particle interpretations and the existing observational constraints on the relevant coupling constant and mass can be relaxed.

Characterization of Stability of Non-Negative Matrix Factorization Models: An Application to Single-Cell Data
Creators: name: Liu, Alexander EJ
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Statistics
subject: FOS: Mathematics

description: The non-negative matrix factorization (NMF) is a powerful machine learning technique used in mathematics, computer science, and data science. This technique has applications in a wide range of fields including recommender systems, image processing, signal processing, machine learning and genetics. Recently, NMF has gained popularity in the analysis of single-cell gene expression data to identify cell types and gene expression patterns. In this thesis, we have studied the NMF, its rank estimation, classification, and stability using both simulated data and real single-cell gene expression data. We have designed two simulated data sets with desired features and tested two seeding methods, eight NMF algorithms and five rank estimation criteria. Additionally, a real single-cell gene expression data has been used to further characterize the NMF algorithms. We have also investigated the stability of NMF, first over the sample size consideration and then on initialization. The detailed conditions that have been revealed by this thesis may generate practical impact in directing the appropriate use of NMF in analyzing single-cell gene expression data.

description: [Abridged] We report Warm Spitzer full-orbit phase observations of WASP-12b at 3.6 and 4.5 micron. We are able to measure the transit depths, eclipse depths, thermal and ellipsoidal phase variations at both wavelengths. The large amplitude phase variations, combined with the planet's previously-measured day-side spectral energy distribution, is indicative of non-zero Bond albedo and very poor day-night heat redistribution. The transit depths in the mid-infrared indicate that the atmospheric opacity is greater at 3.6 than at 4.5 micron, in disagreement with model predictions, irrespective of C/O ratio. The secondary eclipse depths are consistent with previous studies. We do not detect ellipsoidal variations at 3.6 micron, but our parameter uncertainties -estimated via prayer-bead Monte Carlo- keep this non-detection consistent with model predictions. At 4.5 micron, on the other hand, we detect ellipsoidal variations that are much stronger than predicted. If interpreted as a geometric effect due to the planet's elongated shape, these variations imply a 3:2 ratio for the planet's longest:shortest axes and a relatively bright day-night terminator. If we instead presume that the 4.5 micron ellipsoidal variations are due to uncorrected systematic noise and we fix the amplitude of the variations to zero, the best fit 4.5 micron transit depth becomes commensurate with the 3.6 micron depth, within the uncertainties. The relative transit depths are then consistent with a Solar composition and short scale height at the terminator. Assuming zero ellipsoidal variations also yields a much deeper 4.5 micron eclipse depth, consistent with a Solar composition and modest temperature inversion. We suggest future observations that could distinguish between these two scenarios.

description: As the demand for higher data throughput in coherent optical communication systems increases, we need to find ways to increase capacity in existing and future optical communication links. To address the demand for higher spectral efficiencies, we apply end-to-end optimization for joint geometric and probabilistic constellation shaping in the presence of Wiener phase noise and carrier phase estimation. Our approach follows state-of-the-art bitwise auto-encoders, which require a differentiable implementation of all operations between transmitter and receiver, including the DSP algorithms. In this work, we show how to modify the ubiquitous blind phase search (BPS) algorithm, a popular carrier phase estimation algorithm, to make it differentiable and include it in the end-to-end constellation shaping. By leveraging joint geometric and probabilistic constellation shaping, we are able to obtain a robust and pilot-free modulation scheme improving the performance of 64-ary communication systems by at least 0.1bit/symbol compared to square QAM constellations with neural demappers and by 0.05 bit/symbol compared to previously presented approaches applying only geometric constellation shaping.

description: In a companion paper, Murtagh (2012), we discussed how Matte Blanco's work linked the unrepressed unconscious (in the human) to symmetric logic and thought processes. We showed how ultrametric topology provides a most useful representational and computational framework for this. Now we look at the extent to which we can find ultrametricity in text. We use coherent and meaningful collections of nearly 1000 texts to show how we can measure inherent ultrametricity. On the basis of our findings we hypothesize that inherent ultrametricty is a basis for further exploring unconscious thought processes.

description: Our cells and organs need oxygen to function. However, in some disorders such as stroke, heart disease and cancer, our tissues are deprived of oxygen. This lack of oxygen, known as hypoxia, leads to the tissue damage and deregulation that characterizes these diseases. Understanding how tissues respond to low oxygen is therefore an important question in health research. While extensive studies have identified hypoxic responses in cell culture, they leave open the question of how tissues and organisms deal with hypoxia. This is important since tissue-to-tissue crosstalk often underlies hypoxic responses in animals. In their natural ecology, Drosophila have evolved to grow on rotting, fermenting food rich in microorganisms – an environment characterized by low ambient oxygen. Hence, they provide an excellent genetic model system to study how hypoxia influences physiology and development. Here I describe a mechanism for hypoxia tolerance in female Drosophila involving the cytokine Unpaired 3 (Upd3), a JAK/STAT pathway ligand and fly interleukin-6 homolog. I found that Upd3 whole-animal null mutant females, but not males, had reduced survival in hypoxia, indicating that the requirement for Upd3 signaling in hypoxia tolerance is sexually dimorphic. Using tissue-specific RNAi-mediated knockdown, I show that these survival effects require Upd3 production in the enterocyte cells of the fly intestine. I also identified transcription factors, Sima/HIF-1α and Yorkie/YAP, as regulators of Upd3 induction. I showed that intestinal Yorkie signaling was required for part of the Upd3 induction in hypoxia and that fat body Sima/HIF-1α, the classic hypoxia-induced factor required for low oxygen survival, acts non-autonomously to restrain excess intestinal Upd3 levels. I demonstrated that part of the lethality seen in whole-body Sima mutants could be rescued by lowering Upd3 levels. Furthermore, I identified that the gut derived Upd3 targets the fat body to modulate glycolysis which is a necessary adaptation in hypoxia to promote tolerance. These findings suggest Upd3 signaling must be tightly regulated in hypoxia: induction of Upd3 is required to mediate survival in low oxygen, but excessive Upd3 production can lead to a ‘cytokine-storm’-like response which can cause lethality. Previous studies have demonstrated a link between HIF-1α and immune system modulation, thereby already implicating a role of hypoxia in immunity. However, with my discovery that gut derived Upd3 is upregulated in hypoxia and is restrained by fat body Sima/HIF-1α, I have uncovered a role for tissue-to-tissue communication in mediating hypoxia tolerance.

description: To my knowledge, there is not a statistical method that can perform Bayesian variable selection in a setting where there is a semi-continuous response with a non-linear relationship to predictor variables. I have developed a two-part model to accommodate a semi-continuous response, that uses Gaussian processes to capture the non-linear relationship between input variables and outcomes. Bayesian variable selection is induced in both parts of the model through the construction of the kernel matrices. I have employed the Nystr\"{o}m approximation for kernel matrices to reduce the computational complexity that occurs when working with kernel matrices and large sample sizes. I perform simulation studies and determine my method is competitive in prediction and variable selection with methods such as elastic net, and other methods that capture non-linearity such as random forests, and gradient boosted trees. In addition, I apply my method to a coronary artery disease (CAD) dataset from the Duke Database for Cardiovascular Disease (DDCD) to determine key gene expression features associated with the CAD index, a measure of CAD severity.

description: A Rayleigh-type surface acoustic wave (SAW) is used in various fields as classical and quantum information carriers because of its surface localization, high electrical controllability, and low propagation loss. Coupling and hybridization between the SAW and other physical systems such as magnetization, electron charge, and electron spin are the recent focuses in phononics and spintronics. A precise measurement of the surface wave amplitude is often necessary to discuss the coupling strengths. However, there are only a few such measurement techniques and they generally require a rather complex analysis. Here we develop and demonstrate a straightforward measurement technique that can quantitatively characterize the SAW. The technique optically detects the surface waving due to the coherently driven SAW by the optical path modulation. Furthermore, when the measurement system operates in the shot-noise-limited regime, the surface slope and displacement at the optical spot can be deduced from the optical path modulation signal. Our demonstrated technique will be an important tool for SAW-related research.

Publisher: name: University of British Columbia
Year: 2012

description: The purpose of this study was to identify, categorize and describe the insider’s perspective on what helps and what hinders sustainability of School-wide Positive Behavioural Interventions and Supports (PBIS). Seventeen participants involved in sustaining PBIS over several years were interviewed and asked what events significantly affected the durable long term implementation of PBIS. Two hundred and twenty eight critical events were recorded and sorted into emergent unitary clusters based on content analysis. These categories then underwent rigorous reliability and validity checks including expert analysis, interrater agreement, and participant feedback. This process yielded 13 categories used to comprehensively represent the participants’ experience of sustainability: PBIS Teams, Continuous Teaching, Focus on Positives, Staff Ownership, Administrative Involvement, Adaptation, Community of Practise, Use of Data, Involving New Personnel, Access to External Expertise, Priority, Staff Turnover, and Conflict of Personal Beliefs/Mistaken Beliefs.

description: The practice of clinical pastoral care, otherwise termed spiritual care or chaplaincy, in North American and European hospitals provides a case study to explore the historic and ongoing tension between religious worldviews and its others. The tension between religion and modernity, scientific rationalism, secularity, and humanism, among others, have all been presented in dichotomous and hierarchical either/or terms to justify a social imaginary that sees religion in decline. I will argue, firstly, that the very construction of ‘religion and …’ signifies a particular understanding of religion’s nature and role in the episteme of contemporary western societies; and secondly, that in this context, what we mean by religion is currently in flux, that is, ‘religion’ is currently undergoing a significant transformation. Ultimately, I will argue that the transformational potential of religion is not merely its ability to evolve along epistemic shifts but its ability to redescribe the relations between disparate domains. It is within this discursive space that a focus on clinical pastoral care/chaplaincy in modern healthcare contexts provides a particularly appropriate lens through which to reveal the fissures, transformations, and potential for redescription of religion in the 21st century and to begin to imagine its role in mapping the ecological networks between disparate domains. In modern healthcare settings, the role of clinical pastoral care is positioned at a nexus between the patient body, religious or spiritual needs, and a set of totalising secular, materialist, and scientistic discourses. A superficial consideration which assumes these narratives to be incompatible will be challenged by a more nuanced analysis showing the mutual imbrication and necessary tension between such worldviews. In this sense my proposed thesis is part of a broader phenomenological analysis of the current constructions of the nature and role of religion in secular society.

description: In this work, we show that by combining quantum metrology and networking tools, it is possible to extend the baseline of an interferometric optical telescope and thus improve diffraction-limited imaging of point source positions. The quantum interferometer is based on single-photon sources, linear optical circuits, and efficient photon number counters. Surprisingly, with thermal (stellar) sources of low photon number per mode and high transmission losses across the baseline, the detected photon probability distribution still retains a large amount of Fisher information about the source position, allowing for a significant improvement in the resolution of positioning point sources, on the order of 10 μas. Our proposal can be implemented with current technology. In particular, our proposal does not require experimental optical quantum memories.

Impact of abdominal compression on heart and stomach motion for stereotactic arrhythmia radioablation

Subjects: subject: Biophysics--Medical

description: Stereotactic arrhythmia radioablation (STAR) is a promising novel treatment using radiotherapy to treat heart arrhythmias, particularly ventricular tachycardia. Similar to other radiotherapy techniques, the cardiac and respiratory-induced motion throughout the treatment of the target and surrounding organs-at-risk is a common concern for treatment planning and delivery; this may lead to increased radiation exposure to healthy tissue, causing negative side-effects if proper management or mitigation is not considered. Reducing respiratory-induced motion of targets via abdominal compression (AC) is well established as an effective target motion management method for liver patients, which can lead to reduced healthy tissue exposure. However, AC has yet to be studied for its effect on the respiratory-induced motion of cardiac structures. Furthermore, the impact of AC on the motion of the stomach, the primary organ-at-risk for STAR, is also undocumented. The purpose of this thesis is to evaluate motion differences of STAR targets between patients treated with AC against those without (free-breathing) using relative centre of mass translations of contoured cardiac structures as well as the stomach. Motion comparisons were performed in magnitude and range of motion in the three cardinal directions to evaluate the effect of AC on anisotropic treatment margins. The relative motion of potential target locations and the stomach were evaluated to observe possible treatment volume overlap with the stomach, which could cause stomach overexposure. This research indicates that AC has a patient-specific effect on STAR target motion and does not significantly affect the likelihood of stomach overlap with the treatment volume. The primary contribution of this thesis is to recommend that AC not be employed as a respiratory motion management method during future STAR treatments.

description: We study exact correlation functions of N=4 SYM at zero coupling. It has been known that it is convenient to label local gauge invariant operators by irreducible representations of symmetric groups/Brauer algebras. We first review the construction of representation bases from the viewpoint of the enhanced symmetry structure of the free theory. We present a basis of multi-matrix models using elements of Brauer algebras, generalising our previous construction for two matrices. We will compute multi-point functions of the basis with the exact N-dependence. In particular we study three-point functions of a class of BPS operators, and we find that they are given by a branching rule of the Brauer algebra. The three-point functions take a factorised form if representations on the operators satisfy a relation.

description: With the growing importance of diversifying perspectives which frame the security and intelligence field, this study set out to explore the relationship between gender representation and Master’s level intelligence curricula. The purpose was to identify what, if any, examples of gender representation exist using intelligence studies curricula. Using a qualitative explicit content analysis, this research used NVivo to analyze 20 Master’s level course syllabi from Canada, Australia, the United Kingdom, and the United States. It was found that the concept of gender is not explicitly addressed in Master’s level syllabi across Canada, the United States, United Kingdom and Australia. These findings demonstrate three clear takeaways. Firstly, it can be established that while gender itself might not be explicitly addressed, diversity may appear as a substitute theme to encompass the broader attempt to include varied perspectives in intelligence studies syllabi. Secondly, the absence of gender included shows that the structure of the majority of course syllabi, either intentionally or unintentionally, adhere to a predominantly traditional masculine approach. Finally, the findings demonstrate that the lack of inclusion of gender is a common phenomenon across intelligence studies syllabi.

description: A well-established, comprehensive 3-D numerical modulation model is applied to simulate galactic protons, electrons and positrons from May 2011 to May 2015, including the solar magnetic polarity reversal of Solar Cycle 24. The objective is to evaluate how these simulations compare with corresponding AMS observations for 1.0-3.0 GV, and what underlying physics follows from this comparison in order to improve our understanding on how the major physical modulation processes change, especially particle drift, from a negative to a positive magnetic polarity cycle. Apart from their local interstellar spectra, electrons and positrons differ only in their drift patterns, but they differ with protons in other ways such as their adiabatic energy changes at lower rigidity. In order to complete the simulations for oppositely charged particles, antiproton modeling results are obtained as well. Together, the observations and the corresponding modeling indicate the difference in the drift pattern before and after the recent polarity reversal and clarify to a large extent the phenomenon of charge-sign dependence during this period. The effect of global particle drift became negligible during this period of no well-defined magnetic polarity. The resulting low values of all particles' MFPs during the polarity reversal contrast their large values during solar minimum activity, and as such expose the relative contributions and effects of the different modulation processes from solar minimum to maximum activity. We find that the drift scale starts recovering just after the polarity reversal, but the MFPs keep decreasing or remain unchanged for some period after the polarity reversal.

description: We present the first weak-lensing-based scaling relation between galaxy cluster mass, M_wl, and integrated Compton parameter Y_sph. Observations of 18 galaxy clusters at z~0.2 were obtained with the Subaru 8.2-m telescope and the Sunyaev-Zel'dovich Array. The M_wl-Y_sph scaling relations, measured at Delta=500, 1000, and 2500 rho_c, are consistent in slope and normalization with previous results derived under the assumption of hydrostatic equilibrium (HSE). We find an intrinsic scatter in M_wl at fixed Y_sph of 20%, larger than both previous measurements of M_HSE-Y_sph scatter as well as the scatter in true mass at fixed Y_sph found in simulations. Moreover, the scatter in our lensing-based scaling relations is morphology dependent, with 30-40% larger M_wl for undisturbed compared to disturbed clusters at the same Y_sph at r_500. Further examination suggests that the segregation may be explained by the inability of our spherical lens models to faithfully describe the three-dimensional structure of the clusters, in particular, the structure along the line-of-sight. We find that the ellipticity of the brightest cluster galaxy, a proxy for halo orientation, correlates well with the offset in mass from the mean scaling relation, which supports this picture. This provides empirical evidence that line-of-sight projection effects are an important systematic uncertainty in lensing-based scaling relations.

description: The emergence of advanced technologies has increased the need for fast and efficient mobile communication that can facilitate transferring large amounts of data and simultaneously serve multiple users. Future wireless systems will rely on millimeter-wave frequencies, enabled by recent silicon hardware advancements. High-frequency millimeter-wave technology and low-noise receiver front ends and amplifiers are key for improved performance and energy efficiency. This thesis proposes two LNA topologies that offer wide input-power-matched bandwidths and low noise figures, eliminating the need for complex matching networks at the LNA input. These topologies use intrinsic feedback through gate-drain networks and/or the resistance of the SOI-transistor back-gate terminal to achieve the real part of the input impedance. The two LNAs are experimentally demonstrated with two 22-nm FDSOI LNAs. One LNA, matched with the assistance of the gate-drain network, exhibits a bandwidth ranging from 7.7-33.3 GHz, which is further improved to 6-38.7 GHz through the application of the back-gate-resistance method. The two LNAs have noise-figure minima of 1.8 and 1.9 dB, maximum gains of 14.7 and 15.6 dB, and maximum IP1dBs of -9.1 and -7.8 dBm while consuming 10 and 7.8 mW of power and occupying 0.04 and 0.03 mm^2 of active areas, respectively. This thesis also presents the first experimental demonstration of noise/distortion (ND) shaping beamformer. The NDs originating in the receiver itself are spatio-temporally shaped away from the beamformer region of support, thereby permitting their suppression by the beamformer. The demonstrator is a 24.3-28.7 GHz, 79.28 mW 4-port receiver for a 4-element antenna array implemented in 22-nm FDSOI CMOS. When shaping was enabled, the concept demonstrator provided average improvements to the NF and IP1dB of 1.6 dB and 2.25 dB, respectively (compared to a reference design), and achieved NF=2.6 dB and IP1dB=-18.7dBm while consuming 19.8 mW/channel.

description: Scattering amplitudes in three-dimensional N=6 Chern-Simons theory are shown to be non-invariant with respect to the free representation of the osp(6|4) symmetry generators. At tree and one-loop level these "anomalous" terms occur only for non-generic, singular configurations of the external momenta and can be used to determine the form of the amplitudes. In particular we show that the symmetries predict that the one-loop six-point amplitude is non-vanishing and confirm this by means of an explicit calculation using generalized unitarity methods. We comment on the implications of this finding for any putative Wilson loop/amplitude duality in N=6 Chern-Simons theory.

description: We derive the most general homogeneous and isotropic teleparallel geometries, defined by a metric and a flat, affine connection. We find that there are five branches of connection solutions, which are connected via several limits, and can further be restricted to the torsion-free and metric-compatible cases. We apply our results to several classes of general teleparallel gravity theories and derive their cosmological dynamics for all five branches. Our results show that for large subclasses of these theories the dynamics reduce to that of closely related metric or symmetric teleparallel gravity theories, while for other subclasses up to two new scalar degrees of freedom participate in the cosmological dynamics.

Electrochemical and Raman investigation of pyrite and chalcopyrite oxidation
Creators: name: Eghbalnia, Maziar
Publisher: name: University of British Columbia

description: The electrochemical behavior of chalcopyrite and pyrite in acidic ferric solutions was investigated using leaching experiments, electrochemical techniques and micro Raman spectroscopy. The investigation of pyrite-assisted leaching of chalcopyrite concentrate in iron sulfate showed that the catalytic effect of pyrite varies depending on the source of the sample. Cyclic voltammetry using solid paraffin carbon paste electrode demonstrated that the ability of chalcopyrite to reduce ferric ions declines with time spent in the leaching reactor. Single particle microelectrode technique was employed to investigate the electrochemical and semiconducting properties of different pyrite samples by means of cyclic voltammetry, electrochemical impedance spectroscopy and Mott-Schottky methods. Cyclic voltammetry showed a difference in the magnitude of the ferric reduction reaction peaks. An equivalent analogue circuit was used to model the impedance spectra, which led to the conclusion that pyrite samples with lower charge transfer resistance are better catalysts for ferric reduction. Micro Raman investigation revealed that elemental sulfur and intermediate products of pyrite oxidation form on the surface of the effective pyrite sample, while sulfur alone forms on the surface of less effective pyrite. Gold and silver nanoparticles were deposited on pyrite at ambient temperature from colloidal solutions. The modified pyrite was investigated using Electrochemical Impedance Spectroscopy. The results revealed a decrease in charge transfer resistance for the redox couple associated with the modified pyrite. It is concluded that the inconsistencies observed in the kinetics of chalcopyrite leaching in pyrite-assisted leaching are due to erratic electrocatalytic behavior of pyrite samples from different geographical locations with various chemical compositions. The concordance between observations of sluggish charge transfer between energy levels in pyrite and electrolyte in less effective pyrite samples in the leaching experiments strengthens the hypothesis that charge transfer between pyrite and the redox couple in solution is the key step in the process.
