description: This article introduces quaternion non-negative matrix factorization (QNMF), which generalizes the usual non-negative matrix factorization (NMF) to the case of polarized signals. Polarization information is represented by Stokes parameters, a set of 4 energetic parameters widely used in polarimetric imaging. QNMF relies on two key ingredients: (i) the algebraic representation of Stokes parameters thanks to quaternions and (ii) the exploitation of physical constraints on Stokes parameters. These constraints generalize non-negativity to the case of polarized signals, encoding positive semi-definiteness of the covariance matrix associated which each source. Uniqueness conditions for QNMF are presented. Remarkably, they encompass known sufficient uniqueness conditions from NMF. Meanwhile, QNMF further relaxes NMF uniqueness conditions requiring sources to exhibit a certain zero-pattern, by leveraging the complete polarization information. We introduce a simple yet efficient algorithm called quaternion alternating least squares (QALS) to solve the QNMF problem in practice. Closed-form quaternion updates are obtained using the recently introduced generalized HR calculus. Numerical experiments on synthetic data demonstrate the relevance of the approach. QNMF defines a promising generic low-rank approximation tool to handle polarization, notably for blind source separation problems arising in imaging applications.

Impact Parameter Space Interpretation for Generalized Parton Distributions

Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The Fourier transform of generalized parton distribution functions at xi=0 describes the distribution of partons in the transverse plane. The physical significance of these impact parameter dependent parton distribution functions is discussed. In particular, it is shown that they satisfy positivity constraints which justify their physical interpretation as a probability density. The generalized parton distribution H is related to the impact parameter distribution of unpolarized quarks for an unpolarized nucleon, H-tilde is related to the distribution of longitudinally polarized quarks in a longitudinally polarized nucleon, and $E$ is related to the distortion of the unpolarized quark distribution in the transverse plane when the nucleon has transverse polarization.

description: Excerpts from the report Preface: The marketing margin for lard, as described in this report, is the difference between the price a hog slaughterer receives for a unit of lard and the price the consumer pays for the same unit of lard in a retail store. Until about 1930, lard commanded a price per pound equal to or more than many other fresh pork products. Since 1930, lard prices have been decreasing in relation to prices of other hog products. Under present market conditions about 7 percent of the wholesale value of all hog products is for lard, while lard represents 15 percent of the wholesale carcass weight. The marketing margins reported are based largely on average wholesale prices for lard at Chicago reported to the Agricultural Marketing Service, and retail prices for 1-pound cartons of lard sold in retail stores, published by the Bureau of Labor Statistics.

description: Let $ Ω\subset R^d $ have finite positive Lebesgue measure, and let $ \mathcal{L}^{2}(Ω) $ be the corresponding Hilbert space of $ \mathcal{L}^{2} $-functions on $ Ω$. We shall consider the exponential functions $ e_λ $ on $ Ω$ given by $ e_λ(x)=e^{i2πλx} $. If these functions form an orthogonal basis for $ \mathcal{L}^{2}(Ω) $, when $ λ$ ranges over some subset $ Λ$ in $ R^d $, then we say that $ (Ω,Λ) $ is a spectral pair, and that $ Λ$ is a spectrum. We conjecture that $ (Ω,Λ) $ is a spectral pair if and only if the translates of some set $ Ω' $ by the vectors of $ Λ$ tile $ R^d $. In the special case of $ Ω=I^d $, the $ d $-dimensional unit cube, we prove this conjecture, with $ Ω'=I^d $, for $ d \leq 3 $, describing all the tilings by $ I^d $, and for all $ d $ when $ Λ$ is a discrete periodic set. In an appendix we generalize the notion of spectral pair to measures on a locally compact abelian group and its dual.

description: We present the discoveries of a brown dwarf and a low mass star from the Kepler and K2 missions. The newly discovered brown dwarf is EPIC 212036875b and the low mass star is KOI-607b. EPIC 212036875b has a mass of $ M_{b}=52.3\pm 1.9M_J$, a radius of $ R_{b}=0.874\pm 0.017R_J$, and orbits its host star in $ P=5.169885 \pm 0.000027$ days. Its host star is a late F-type star with $ M_\star=1.288\pm 0.065M_\odot$, $ R_\star=1.498\pm 0.025R_\odot$, and $ T_{\rm eff}=6238 \pm 60$K. KOI-607b has a mass of $ M_{b}=95.1\pm 3.4M_J$, a radius of $ R_{b}=1.089\pm 0.089R_J$, and an orbital period of $ P=5.89399148 \pm 0.00000060$ days. The primary star in the KOI-607 system is a G dwarf with $ M_\star=0.993\pm 0.052M_\odot$, $ R_\star=0.915\pm 0.031R_\odot$, and $ T_{\rm eff} = 5418\pm 87$K. We also revisit a brown dwarf, CWW 89Ab, that was previously published by Nowak et al. 2017 (under the designation EPIC 219388192b). CWW 89Ab is one of two known transiting brown dwarfs associated with a star cluster, which illustrates the need for more brown dwarfs with accurate masses and radii and reliable age determinations to test theoretical models. We find that the newly discovered brown dwarf, EPIC 212036875b, falls in the middle of the so-called "brown dwarf desert", indicating that EPIC 212036875b is either a particularly rare object, or the brown dwarf desert may not be so dry after all.

Underground Mine Rehabilitation for Closure : A Uranium Case Study
Creators: name: Longo, Sue
name: Crossley, Chloe
Publisher: name: The University of British Columbia
Year: 2024

description: Historical mine sites pose multiple challenges for final closure. Environmental legacies are a common area of concern, but physical stability of the site is equally important for a long-term, walk away solution. This paper will discuss the status of the underground workings of a decommissioned uranium mine and the paste backfill solution that was developed and implemented. Specifically, the physical hazards that are being addressed are near surface hazards e.g. empty underground stopes with thin crown pillars and surface openings to the underground e.g. glory holes and raises. The consequence of not addressing these hazards is potential long-term failure e.g. surface collapse, cracking and subsidence which could have an impact on flora and fauna in the area as well as the nearby local population. Additionally, the impact on the closure of the overall site and the lessons learned during the construction program will be discussed.

The research aimed to examine mental illness and suicide in the context of other distal and proximal factors and stressors. The research demonstrated people exposed to stressors other than mental illness are dying by suicide and this is, at least sometimes, in the absence of any diagnosed mental illness. Additionally, even within the population who have a diagnosed mental illness, the pathways or life trajectories to suicide are complex and varied.

Axial instability of rotating relativistic stars

description: Perturbations of rotating relativistic stars can be classified by their behavior under parity. For axial perturbations (r-modes), initial data with negative canonical energy is found with angular dependence $e^{imϕ}$ for all values of $m\geq 2$ and for arbitrarily slow rotation. This implies instability (or marginal stability) of such perturbations for rotating perfect fluids. This low $m$-instability is strikingly different from the instability to polar perturbations, which sets in first for large values of $m$. The timescale for the axial instability appears, for small angular velocity $Ω$, to be proportional to a high power of $Ω$. As in the case of polar modes, viscosity will again presumably enforce stability except for hot, rapidly rotating neutron stars. This work complements Andersson's numerical investigation of axial modes in slowly rotating stars.

Structure-based Design of Small Molecule Inhibitors of HIV-1 Entry
Creators: Le-Khac, Matthew
Publisher: name: Columbia University
Year: 2013
Subjects: Biochemistry

description: HIV infection begins when gp120 envelope protein on the viral surface binds to the CD4 receptor on the host cell. This initial protein-protein interaction starts the rest of the HIV lifecycle of coreceptor binding, fusion and replication. One of the targets of HIV entry inhibitors is the interaction between CD4 and gp120. A large percentage of CD4-gp120 contacts revolved around a cavity in gp120 in which the PHE43 residue of CD4 caps.
We were able to design and synthesize a progression of small molecule compounds targeting the PHE43CD4 cavity in gp120 based on a previous CD4-mimetic, NBD-556. By either soaking or co-crystallizing the newly designed compounds bound to gp120, we were able to solve four x-ray crystal structures in order to observe the interactions with the binding cavity on the atomic level. Using x-ray crystal structure, isothermal calorimetry and viral binding assay to guide design, we were able to improve the binding affinity more than 30 fold compared to the original NBD-556. Our most potent compound DMJ-II-121-R,R is able to bind to gp120 at a Kd of 0.11 micromolar and specifically block HIV-1 entry at an IC50 of 2.3 micromolar. Along with improved potency, the new design alleviated the agonistic properties of the original NBD-556, which was inducing gp120 to bind to the coreceptors on the host cell instead of blocking the progression of the HIV lifecycle.
In parallel, we also utilized the soakable gp120 crystal system to screen a library of 352 fragments of various shapes using x-ray crystallography to detect and identify two positive hits, benzimidazole and 3-hydroxyphenylacetic acid. The possible leads from the two identified fragments along with our improved potency of NBD-556 based derivatives offer valuable insight to guide us on the development toward a subnanomolar small molecular antagonist of gp120-CD4 binding.

description: This thesis explores habit theory in the realm of sugary drink consumption. Through a narrative review and empirical investigation I found that individuals with a stronger habit of drinking sugary drinks have limited control over their drink behaviour. Nonetheless, when exposed to educational campaigns, they do appear to be able to take control over their drink behaviour and respond to the intervention accordingly. I also found that the two most common measures of habit capture different constructs. Together, this research highlights a number of common assumptions within the habit literature and provides the foundations for more research in this area.

description: We derive a criterion that is convenient for applications and exactly characterizes the test function space on which the operator realization of a given series of Wick powers of a free field is possible. The suggested derivation does not use the assumption that the metric of the state space is positive and can therefore be used in a gauge theory. It is based on the systematic use of the analytic properties of the Hilbert majorant of the indefinite metric and on the application of a suitable theorem on the unconditional convergence of series of boundary values of analytic functions.

description: Gravitational wave astrophysics relies heavily on the use of matched filtering both to detect signals in noisy data from detectors, and to perform parameter estimation on those signals. Matched filtering relies upon prior knowledge of the signals expected to be produced by a range of astrophysical systems, such as binary black holes. These waveform signals can be computed using numerical relativity techniques, where the Einstein field equations are solved numerically, and the signal is extracted from the simulation. Numerical relativity simulations are, however, computationally expensive, leading to the need for a surrogate model which can predict waveform signals in regions of the physical parameter space which have not been probed directly by simulation. We present a method for producing such a surrogate using Gaussian process regression which is trained directly on waveforms generated by numerical relativity. This model returns not just a single interpolated value for the waveform at a new point, but a full posterior probability distribution on the predicted value. This model is therefore an ideal component in a Bayesian analysis framework, through which the uncertainty in the interpolation can be taken into account when performing parameter estimation of signals.

The measured cross-section is compared with the prediction of the PYTHIA MC model. The obtained value of the diquark suppression factor in the Lund string model is different from that obtained in e+e- data. The dependence of the cross-section as a function of the transverse mass M_T is shown to be similar for different hadrons produced in photoproduction at HERA.

description: In this thesis the relationship between the acquisition of novel plants from the wild for use in ornamental horticulture, commonly referred to as Plant Hunting, and access and benefit sharing introduced under the Nagoya Protocol (2010), part of the United Nations Convention on Biological Diversity (CBD), is investigated. The Nagoya Protocol allows for countries to set out terms under which access may be given to their indigenous genetic resources in return for benefits from any research and development of those genetic resources. Many countries also put their own restrictions on the commercialisation of wild plants and seed. The key question that this thesis sets out to address is as follows: 'Plant hunting for commercial horticulture and access and benefit sharing: complementary or competitive uses of wild novel plants?'

description: The digital age has made pornography omnipresent, stimulating, and easily accessible. Sarah Ashton investigated how young women make sense of this phenomenon. Her interviews with women revealed that pornography plays complex, often contradictory, roles in women’s lives, implicated in both beneficial and harmful outcomes. Of particular importance were matters of pleasure, consent, and intimate relationships. The evidence that men’s needs are prioritised over women’s alerts practitioners in public health and psychology to challenge such disparities in their clinical work and public communications. The publications arising from Sarah Ashton’s research include a refinement of the definition of pornography to incorporate consent.

description: The semiclassical collapse of a sphere of quantized dust is studied. A Born-Oppenheimer decomposition is performed for the wave function of the system and the semiclassical limit is considered for the gravitational part. The method of adiabatic invariants for time dependent Hamiltonians is then employed to find (approximate) solutions to the quantum dust equations of motions. This allows us to obtain corrections to the adiabatic approximation of the dust states associated with the time evolution of the metric. The diverse non-adiabatic corrections are generally associated with particle (dust) creation and related fluctuations. The back-reaction due to the dominant contribution to particle creation is estimated and seen to slow-down the collapse.

CPT approach to evaluating flow liquefaction using yield stress ratio
Creators: name: Mayne, Paul W.

Publisher: name: The University of British Columbia
Year: 2024

description: Piezocone penetration testing (CPTu) is a well-utilized tool for geotechnical studies by the mining industry to evaluate the state, strength, and stability of tailings and mine wastes. Of particular concern to tailings are the conditions prone to flow liquefaction which consist of contractive geomaterials that are normallyconsolidated (NC) to lightly-overconsolidated (LOC) silty to sandy soils. Using an established relationship for assessing yield stress (σp', or apparent preconsolidation stress) in terms of the net cone resistance and CPTu material index (Ic), the interpreted profile of yield stress with depth is used to discern the boundaries between contractive and dilative soils within the context of critical state soil mechanics. The methodology is analogous to the concept of state parameter () where the contractive-dilative demarcation is taken theoretically at  = 0. Alternatively, a critical threshold is defined in terms of yield stress ratio (YSR = σp'/σvo') and contractive soils are identified when YSR is less than approximately 3, where σvo' = current effective overburden stress. The YSR method is applied to three case studies, including the recent tailings dam failure near Brumadinho, Brazil in January 2019.

description: The purpose of this document is to gather in one place some basic knowledge about the institutional and economic framework for Community Radio in Ireland, Romania, and Portugal. In particular, we will try to summarize the main rules and regulations
 defining the process to obtain the licenses for broadcasting in these countries and the economic management of stations and sources of income, as well as the main initial costs experienced by the stations of the Grassroots Wavelengths project.
 One of the objectives of the project is to support the communities involved in the definition of station governance strategies. From the beginning, we realized how different institutional and economic frameworks in different contexts have a strong influence on the processes of creation and management of the stations. Therefore, we considered it important to describe these frameworks as simply as possible so that both the actors involved and new communities interested in starting their experience with a community radio could benefit from them.

"Like a Debussy Prelude flowing across the different registers of the piano..." Mathew Lorenson,Realtime,125 September15.

The Fourth Estate is a societal, political or institutional force whose influence is not officially recognised, and is a term often used to refer to the press. It’s original use relates to the three estates of the realm: clergy, nobility and commoners. Australia in particular has seen just how powerful ‘unofficail’ voices can be, through monopolisation of the media, editorialised media reporting and political bias. The Fourth Estate is a work that compares the sonoric qualities of the piano with those of small electronic devices that extend and contrast with it. Small voices that have the ability to change everything. As the Fourth Estate is thought to be an element of society ‘outside’ official recognition, here the electronics attempt to pull the piano into a different sound world outside its usual realm.

 To perform this work you will need the Decibel Score player. Each iteration of the score materials is unique and requires the score player to do this. A digital or hard copy of the score is available from Material Press.

description: This paper presents a novel nonlinear pose filter evolved directly on the Special Euclidean Group SE(3) with guaranteed characteristics of transient and steady-state performance. The above-mention characteristics can be achieved by trapping the position error and the error of the normalized Euclidean distance of the attitude in a given large set and guiding them to converge systematically to a small given set. The error vector is proven to approach the origin asymptotically from almost any initial condition. The proposed filter is able to provide a reliable pose estimate with remarkable convergence properties such that it can be fitted with measurements obtained from low-cost measurement units. Simulation results demonstrate high convergence capabilities and robustness considering large error in initialization and high level of uncertainties in measurements.

description: Tensors, a.k.a. multi-dimensional arrays, arise naturally when modeling higher-order objects and relations. Among ubiquitous applications including image processing, collaborative filtering, demand forecasting and higher-order statistics, there are two recurring themes in general: tensor recovery and tensor decomposition. The first one aims to recover the underlying tensor from incomplete information; the second one is to study a variety of tensor decompositions to represent the array more concisely and moreover to capture the salient characteristics of the underlying data. Both topics are respectively addressed in this thesis.
      Chapter 2 and Chapter 3 focus on low-rank tensor recovery (LRTR) from both theoretical and algorithmic perspectives. In Chapter 2, we first provide a negative result to the  sum of nuclear norms (SNN) model---an existing convex model widely used for LRTR; then we propose a novel convex model and prove this new model is better than the SNN model in terms of the number of measurements required to recover the underlying low-rank tensor. In Chapter 3, we first build up the connection between robust low-rank tensor recovery and the compressive principle component pursuit (CPCP), a convex model for robust low-rank matrix recovery. Then we focus on developing convergent and scalable optimization methods to solve the CPCP problem. In specific, our convergent method, proposed by combining classical ideas from Frank-Wolfe and proximal methods, achieves scalability with linear per-iteration cost.
      Chapter 4  generalizes the successive rank-one approximation (SROA) scheme for matrix eigen-decomposition to a special class of tensors called symmetric and orthogonally decomposable (SOD) tensor. We prove that the SROA scheme can robustly recover the symmetric canonical decomposition of the underlying SOD tensor even in the presence of noise. Perturbation bounds, which can be regarded as a higher-order generalization of the Davis-Kahan theorem, are provided in terms of the noise magnitude.

description: This paper is devoted to an approximation problem for operators in Hilbert space, that appears when one tries to study geometrically the cascade algorithm in wavelet theory. Let $ H $ be a Hilbert space, and let $ π$ be a representation of $ L^\infty(T) $ on $ H $. Let $ R $ be a positive operator in $ L^\infty(T) $ such that $ R(1)=1 $, where $ 1 $ denotes the constant function $ 1 $. We study operators $ M $ on $ H $ (bounded, but non-contractive) such that $ π(f)M=Mπ(f(z^2)) $ and $ M^* π(f)M=π(R^* f) $, $ f \in L^\infty (T) $, where the $ * $ refers to Hilbert space adjoint. We give a complete orthogonal expansion of $ H $ which reduces $ π$ such that $ M $ acts as a shift on one part, and the residual part is $ H^{(\infty)}=\bigcap_n[M^n H] $, where $ [M^n H] $ is the closure of the range of $ M^n $. The shift part is present, we show, if and only if $ \ker(M^*) \neq \{0\} $. We apply the operator-theoretic results to the refinement operator (or cascade algorithm) from wavelet theory. Using the representation $ π$, we show that, for this wavelet operator $ M $, the components in the decomposition are unitarily, and canonically, equivalent to spaces $ L^2(E_n) \subset L^2(R) $, where $ E_n \subset R $, $ n=0,1,2,...,\infty $, are measurable subsets which form a tiling of $ R $; i.e., the union is $ R $ up to zero measure, and pairwise intersections of different $ E_n $'s have measure zero. We prove two results on the convergence of the cascade algorithm, and identify singular vectors for the starting point of the algorithm.

Nonpartonic effects in pion electroproduction in the HERMES kinematical region

description: The presentation is concerned with higher twist corrections of nonpartonic origin to semi-inclusive observables in the kinematical region relevant for the HERMES experiment. We demonstrate a strong impact of the VDM-like interaction and the exclusive production of $ρ^0$ meson on the extraction of the $\bar d - \bar u$ asymmetry from charged pion DIS multiplicities. We also show that it is the exclusive-$ρ^0$ channel which accounts for the experimentally observed effect of the excess of charged over neutral pions produced at large $z$.

description: By different methods we show that for dynamical chaos in the standard map with critical golden curve the Poincaré recurrences P(τ) and correlations C(τ) asymptotically decay in time as P ~ C/τ~ 1/τ^3. It is also explained why this asymptotic behavior starts only at very large times. We argue that the same exponent p=3 should be also valid for a general chaos border.

Generalized Fast-Convolution-based Filtered-OFDM: Techniques and Application to 5G New Radio

description: This paper proposes a generalized model and methods for fast-convolution (FC)-based waveform generation and processing with specific applications to fifth generation new radio (5G-NR). Following the progress of 5G-NR standardization in 3rd generation partnership project (3GPP), the main focus is on subband-filtered cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM) processing with specific emphasis on spectrally well localized transmitter processing. Subband filtering is able to suppress the interference leakage between adjacent subbands, thus supporting different numerologies for so-called bandwidth parts as well as asynchronous multiple access. The proposed generalized FC scheme effectively combines overlapped block processing with time- and frequency-domain windowing to provide highly selective subband filtering with very low intrinsic interference level. Jointly optimized multi-window designs with different allocation sizes and design parameters are compared in terms of interference levels and implementation complexity. The proposed methods are shown to clearly outperform the existing state-of-the-art windowing and filtering-based methods.

Post-Córrego do Feijão : Continued Evolution of Tailings Dam Regulations in Brazil

description: The failure of Dam I at Vale’s Córrego do Feijão iron ore mine near Brumandinho, Brazil, on January 25, 2019, was not only shocking and devastating, but raised the industry’s radar with respect to so-called “inactive” tailings dams. With an anticipated death toll of approximately 270, this failure may be the worst industrial accident in Brazil’s history. Mere days after the failure, new regulations were imposed in the state of Minas Gerais, while a couple of weeks later, more strict regulations were proposed for tailings management within the entirety of Brazil. The public’s trust of the mining industry in Brazil has further degraded because of this failure, and hence the regulatory environment continues to evolve with a corresponding increase in regulatory controls. This paper is a sequel to a paper published in the proceedings of Tailings & Mine Waste ’18, titled “Changes to Tailings Dam Regulation in Brazil in the Aftermath of Failures,” which highlighted the post-Samarco regulatory changes.
