description: In the current study, a quantum-cascade-laser-based dual-comb spectrometer (DCS) was used to paint a detailed picture of a 1.0 ms high-temperature reaction between propyne and oxygen. The DCS interfaced with a shock tube to provide pre-ignition conditions of 1225 K, 2.8 atm, and 2% p-C3H4/18% O2/Ar. The spectrometer consisted of two free-running, non-stabilized frequency combs each emitting at 179 wavelengths between 1174 and 1233 cm-1. A free spectral range, f_r, of 9.86 GHz and a difference in comb spacing, Δf_r, of 5 MHz, enabled a theoretical time resolution of 0.2 us but the data was time-integrated to 4 us to improve SNR. The accuracy of the spectrometer was monitored using a suite of independent laser diagnostics and good agreement observed.

Filter-pressed tailings facility design, construction, and operating guidelines

Publisher: name: The University of British Columbia
Year: 2016

description: Filter-pressed tailings facilities have been designed, constructed, and operated since the late 1980 when Greens Creek, Alaska first adopted the method. Currently more and more mining companies are considering filter-pressed tailings management as a way to reduce water consumption and possibly reduce the risk of failure of the tailings facility. This paper describes guidelines for decision making in support of the design, construction, and operation of filter-pressed tailings facilities. The guidelines are based on recent projects on which the authors have worked. The paper emphasizes the need to characterise the site, establish realistic tailings properties, take into account site-specific climate and seismicity, and the possible need to amend tailings to achieve moisture contents that facilitate compaction and strength gain of the tailings. The paper discusses alternate stack geometries that may be required to facilitate construction, achieve moisture control, manage surface water, and limit seepage and groundwater impact. Finally the paper proposes a risk assessment approach to guide selection of tolerable risks that are inevitably involved in all tailings operations—and pursue the goal of a zero-failure operation.
Kolmogorov-Sinai entropy-rate vs. physical entropy

description: This paper elucidates the connection between the KS entropy-rate kappa and the time evolution of the physical or statistical entropy S. For a large family of chaotic conservative dynamical systems including the simplest ones, the evolution of S(t) for far-from-equilibrium processes includes a stage during which S is a simple linear function of time whose slope is kappa. The paper presents numerical confirmation of this connection for a number of chaotic symplectic maps, ranging from the simplest 2-dimensional ones to a 4-dimensional and strongly nonlinear map.

A valid species, Tenthredo (Tenthredella) mordax Konow, 1908.
Types. Tenthredo mordax Konow, 1908: 25–26. Syntype (s) ♀, “ Sikkim ”. Lectotype ♀, hereby designated, (MNCN_ Ent 100205, MNCN Cat. Tipos Nº 8138, Fig. 28, see also http://dx.doi.org/10.6084/m9.figshare.762439). Type locality: India, Sikkim.
Discussion. There is no indication in the original description, how many specimens Konow had to hand. Very likely it was a single female, which is selected here as lectotype. Apparently, after Konow (1908) nobody examined the type. Malaise (1945) followed only the original description, and Saini (207: 132) claimed that the type should be in the SDEI and is lost. The description given by Saini does not completely agree with the type specimen (e.g., several white marks on head and thorax). Possibly he treated a different species under the name T. mordax. Tenthredo mordax may be placed in the subgenus Tenthredella Rohwer, 1910.

description: Emergence of multiple topological phases with a series of Chern numbers, $\pm 1$, $\mp 1$, $\pm 2$, $\mp 2$, $\pm 3$ and $\mp 4$, are observed in a ferromagnetic Kitaev-Heisenberg-spin-anisotropic model on honeycomb lattice with further neighbor interactions in the presence of an external magnetic field. Magnon Chern insulating dispersions of this two-band model are studied by using linear spin-wave theory formulated on the exact ferromagnetic ground state. Magnon edge states are obtained for the respective topological phases along with density of states. A topological phase diagram of this model is presented. Behavior of thermal Hall conductivity for those phases is studied. Sharp jumps of thermal hall conductivity is noted near the vicinity of phase transition points. Topological phases of the Kitaev spin-liquid compounds, $α$-RuCl$_3$, X$_2$IrO$_3$, X = (Na, Li) and CrY$_3$, Y = (Cl, Br, I) are characterized based on this theoretical findings.

description: This paper studies the decay of a large, closed domain wall in a closed universe. Such walls can form in the presence of a broken, discrete symmetry. We study a novel process of quantum decay for such a wall, in which the vacuum fluctuates from one discrete state to another throughout one half of the universe, so that the wall decays into pure field energy. Equivalently, the fluctuation can be thought of as the nucleation of a second closed domain wall of zero size, followed by its growth by quantum tunnelling and its collision with the first wall, annihilating both. We therefore study the 2-wall system coupled to a spherically symmetric gravitational field. We derive a simple form of the 2-wall action, use Dirac quantization, obtain the 2-wall wave function for annihilation, find from it the barrier factor for this quantum tunneling, and thereby get the decay probability. This is the second paper of a series.

Die bestehenden Querverbindungen beziehen sich also auf die mechanisch-thermischen Einwirkungen bei strömenden Medien. Die Beschreibung dieser beiden physikalischen Einflüsse bedient sich dabei bestimmter auf Erfahrung, Experiment und Theorie begründeter Axiome.

Improved Perturbative QCD Approach to the Bottomonium Spectrum

description: Recently it has been shown that the gross structure of the bottomonium spectrum is reproduced reasonably well within the non-relativistic boundstate theory based on perturbative QCD. In that calculation, however, the fine splittings and the S-P level splittings are predicted to be considerably narrower than the corresponding experimental values. We investigate the bottomonium spectrum within a specific framework based on perturbative QCD, which incorporates all the corrections up to O(alpha_S^5 m_b) and O(alpha_S^4 m_b), respectively, in the computations of the fine splittings and the S-P splittings. We find that the agreement with the experimental data for the fine splittings improves drastically due to an enhancement of the wave functions close to the origin as compared to the Coulomb wave functions. The agreement of the S-P splittings with the experimental data also becomes better. We find that natural scales of the fine splittings and the S-P splittings are larger than those of the boundstates themselves. On the other hand, the predictions of the level spacings between consecutive principal quantum numbers depend rather strongly on the scale mu of the operator \propto C_A/(m_b r^2). The agreement of the whole spectrum with the experimental data is much better than the previous predictions when mu \simeq 3-4 GeV for alpha_S(M_Z)=0.1181. There seems to be a phenomenological preference for some suppression mechanism for the above operator.

Numerical model comparison on deformation behavior of a TSF embankment subjected to earthquake loading

Publisher: name: The University of British Columbia
Year: 2016

description: This paper introduces two independent numerical modeling approaches used to investigate the earthquake response of a tailings embankment dam on a foundation consisting of liquefiable alluvial soil. The approaches employ non-linear two-dimensional finite-difference and finite-element numerical schemes along with fully-coupled effective stress constitutive models for liquefaction. Details of the parameters describing each liquefaction constitutive model and results of model calibration against experimental data from liquefaction cyclic triaxial tests are presented. Comparison of numerical results addressing the seismic performance of the analyzed embankment-liquefiable foundation system indicates agreement between the two independent modeling approaches in terms of predicted deformation pattern of the system and magnitude of permanent dam displacement. The study demonstrates that both considered numerical modeling approaches represent a useful and robust tool for analyzing the deformation behavior of tailings dams on liquefiable foundation under seismic conditions.

description: We experimentally realize a highly tunable superfluid oscillator circuit in a quantum gas of ultracold atoms and develop and verify a simple lumped-element description of this circuit. At low oscillator currents, we demonstrate that the circuit is accurately described as a Helmholtz resonator, a fundamental element of acoustic circuits. At larger currents, the breakdown of the Helmholtz regime is heralded by a turbulent shedding of vortices and density waves. Although a simple phase-slip model offers qualitative insights into the circuit's resistive behavior, our results indicate deviations from the phase-slip model. A full understanding of the dissipation in superfluid circuits will thus require the development of empirical models of the turbulent dynamics in this system, as have been developed for classical acoustic systems.

description: Galactic nuclei are important for studies of galaxy evolution, stellar dynamics and general relativity. Many have Supermassive Black Holes (SMBHs) (with one million to one billion times the mass of the sun) that affect the large scale properties of their hosts. They are also the densest known stellar systems, and produce unique electromagnetic and gravitational wave sources via close encounters between stars and compact objects. For example, stars that wander too close to an SMBH are tidally disrupted, producing a bright flare known as a TDE. This thesis investigates the gas and stellar environments in galactic nuclei. In Chapters 2 and 3, we develop an analytic model for the gas environment around quiescent SMBHs. In the absence of large scale inflows, winds from the local stellar population will supply most of the gas. The gas density on parsec scales depends strongly on the star formation history, and can plausibly vary by four orders of magnitude. In Chapter 3, we use this model to constrain the presence of jets in a large sample of TDE candidates. In Chapter 4 we construct observationally motivated models for the distributions of stars and stellar remnants in our Galactic Center. We then calculate rates of various collisional stellar interactions, including the tidal capture of stars by stellar mass black holes. This process produces ~100 black hole LMXBs in the central parsec of the Galaxy (comparable to the number inferred from recent X-ray studies).

description: While fabrication of certain offshore structural cutter ladder components, a situation can arise where the gap may formed due to assembly level exceeded tolerance limit, improper heat or process control during fabrication. This gap will lead to reduce the pretension force and design life of bolt as well matting part hence fatigue failure will happen in the connection due to lack of slip resistance on the joint. The slip resistance and design life can be improved by adding shims on the connection is gaps are presented in the connection. In this research work is mainly focusing on the assembly level gap on cutter ladder lower part and upper part assembly connection, this gap may lead to inadequate design life failure in dynamic load applied on that

description: We consider autonomous Lagrangian systems with two degrees of freedom, having an hyperbolic equilibrium of saddle-saddle type (that is the eingenvalues of the linearized system about the equilibrium are $\pm λ_1, \pm λ_2 $, $λ_1, λ_2 > 0$). We assume that $λ_1 > λ_2$ and that the system possesses two homoclinic orbits. Under a nondegeneracy assumption on the homoclinics and under suitable conditions on the geometric behaviour of these homoclinics near the equilibrium we prove, by variational methods, then they give rise to an infinite family of multibump homoclinic solutions and that the topological entropy at the zero energy level is positive. A method to deal also with homoclinics satisfying a weaker nondegeneracy condition is developed and it is applied, for simplicity, when $λ_1 \approx λ_2$. An application to a perturbation of a uncoupled system is also given.

description: In this Dissertation we explore how the nature of tidal interactions tear gravitationally bound systems apart into distinct morphological and kinematic structures. We use the properties of these structures, persisting for billions of years, to investigate the potential of the Milky Way Galaxy and to disentangle the baryonic evolution of gas in dwarf galaxy interactions. We approach these problems through a combination of observations, and simulations, as well as comparisons between the two.
      In particular, we use the properties of the thin, curved stellar stream emerging from the old, Milky Way globular cluster, Palomar 5 (Pal 5) to show that its mere existence can rule out a moderately triaxial potential model of our Galaxy. Pal 5-like streams on appropriate orbits diffuse much further in space from the orbital path (dubbed “stream-fanning”) in this triaxial potential than in the oblate case. We further show that torques from the Milky Way’s Galactic bar, can create ever-widening gaps in stellar streams. The fact that the bar can create such under densities, demonstrates that we should be careful when interpreting gaps in stellar streams as indirect evidence of the existence of dark matter subhalos in our Galaxy.
      We carry out a systematic study of resolved neutral hydrogen (HI) synthesis maps of 10 interacting dwarf galaxy pairs. The pairs are located in a range of environments and captured at various interaction stages. We find that the neutral gas is extended in the interacting pairs when compared to non-paired analogs, indicating that gas is tidally pre- processed. Additionally, we find that dwarf-dwarf interactions enable the “parking” of gas at large distances to serve as a continual gas supply channel to the dwarfs until accretion by a more massive host.
      We model a specific dwarf pair in our sample, NGC 4490/85, which is an isolated analog of the Magellanic Clouds and is surrounded by a ∼50 kpc extended HI envelope. We use hybrid N-body and test-particle simulations along with a visualization interface to simultaneously reproduce the observed present-day morphology and kinematics. Our numerical results con- firm that encounters between two dwarf galaxies can “park” baryons at very large distances, without the aid of environmental effects. The extended tidal features will continue to evolve over several billion years which will affect the efficiency of gas stripping if such dwarf pairs are accreted by a massive host. In contrast, in isolated environments dwarf-dwarf interactions can create a long-lived supply mode of gas to the merger remnant potentially explaining the population of dwarfs in the field with large gas envelopes, but limited star formation. All of these topics share the common theme of utilizing morphological and kinematic structures left behind from ongoing gravitational interactions on various scales.
A fully (3+1)-D Regge calculus model of the Kasner cosmology

description: We describe the first discrete-time 4-dimensional numerical application of Regge calculus. The spacetime is represented as a complex of 4-dimensional simplices, and the geometry interior to each 4-simplex is flat Minkowski spacetime. This simplicial spacetime is constructed so as to be foliated with a one parameter family of spacelike hypersurfaces built of tetrahedra. We implement a novel two-surface initial-data prescription for Regge calculus, and provide the first fully 4-dimensional application of an implicit decoupled evolution scheme (the ``Sorkin evolution scheme''). We benchmark this code on the Kasner cosmology --- a cosmology which embodies generic features of the collapse of many cosmological models. We (1) reproduce the continuum solution with a fractional error in the 3-volume of 10^{-5} after 10000 evolution steps, (2) demonstrate stable evolution, (3) preserve the standard deviation of spatial homogeneity to less than 10^{-10} and (4) explicitly display the existence of diffeomorphism freedom in Regge calculus. We also present the second-order convergence properties of the solution to the continuum.

Discussion. The taxon belongs to the Megalodontes cephalotes complex, and might be only a very pale form of cephalotes. Hitherto only known from the types, all collected on 7.7. 1902 in Los Molinos near Madrid. This would be the westernmost locality known for cephalotes (except for a specimen from Beges, Cantabria). Very similar pale forms of cephalotes (forma f according to Taeger 2002) are known from the Spanish Pyrenees, but these are less sculptured than mundus. Megalodontes species usually show clear differences in their COI barcodes. Perhaps fresh specimens might help to clarify the status of the taxon.

description: The purpose of this dissertation is to develop the Response Inventory to Stereotype-threatening Environments Questionnaire (RISE-Q), a multidimensional measure of the intentional cognitive and behavioral strategies women in science, technology, engineering, and mathematics (STEM) occupations engage to contend with systemic stereotype threat. Hundreds of studies demonstrate negative effects of stereotype threat relevant to women’s workplace experiences (for a review see Walton, Murphy, & Ryan, 2015). However, most focus on acute processes and effects, those that are immediate and temporary in response to a single cue. Less is known about how individuals respond to the experience of chronic stereotype threat (Block, Koch, Liberman, Merriweather, & Roberson, 2011). This has implications for organizations because it is unlikely stereotype threat is only experienced as an acute state in the workplace (Kalokerinos, von Hippel, & Zacher, 2014), and it is the accumulation of stereotype threat-activating cues that may lead to permanent outcomes (Steele, Spencer, & Aronson, 2002). In order to address this gap and contribute to research on women’s career experiences in STEM (Makarem & Wang, 2019), this dissertation develops the RISE-Q, an inventory of three separate, but related, response pattern scales based on three response patterns previously identified by Block, Cruz, Bairley, Harel-Marian, & Roberson (2019): (1) Fending Off the Threat, (2) Confronting the Threat, and (3) Sustaining Self in the Presence of Threat. Seventy-two items across three response pattern scales were developed and tested in a sample of 726 women who currently work in STEM occupations. Results from Exploratory Factor Analyses (EFAs) of data collected from a Qualtrics Panel sample (n = 378) demonstrated each response pattern scale consisted of four factors reflecting four specific strategies. A series of Confirmatory Factor Analyses (CFAs) using data collected from online “women in STEM” networks (n = 348) provided evidence for moderate model fit for the Fending Off response pattern scale, and good model fit for the Confronting Threat and Sustaining Self scales. Assessments of internal consistency reliabilities for all three response pattern scales and associated subscales demonstrated strong internal consistency. Further analyses provided strong evidence of convergent validity and criterion-related validity for all three scales. Initial results for the RISE-Q are promising. Implications and directions for future research are discussed.

description: The Legendre transform expresses dynamics of a classical system through first-order Hamiltonian equations. We consider coherent state transforms with a similar effect in quantum mechanics: they reduce certain quantum Hamiltonians to first-order partial differential operators. Therefore, the respective dynamics can be explicitly solved through a flow of points in extensions of the phase space. This generalises the geometric dynamics of a harmonic oscillator in the Fock space. We describe all Hamiltonians which are geometrised (in the above sense) by Gaussian and Airy beams and write down explicit solutions for such systems.

description: New sets of CMS underlying-event parameters ("tunes") are presented for the PYTHIA8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-next-to-leading (NNLO) orders in perturbative quantum chromodynamics, and the strong coupling evolution at LO or NLO. Measurements of charged-particle multiplicity and transverse momentum densities at various hadron collision energies are fit simultaneously to determine the parameters of the tunes. Comparisons of the predictions of the new tunes are provided for observables sensitive to the event shapes at LEP, global underlying event, soft multiparton interactions, and double-parton scattering contributions. In addition, comparisons are made for observables measured in various specific processes, such as multijet, Drell-Yan, and top quark-antiquark pair production including jet substructure observables. The simulation of the underlying event provided by the new tunes is interfaced to a higher-order matrix-element calculation. For the first time, predictions from PYTHIA8 obtained with tunes based on NLO or NNLO PDFs are shown to reliably describe minimum-bias and underlying-event data with a similar level of agreement to predictions from tunes using LO PDF sets.

description: Although research speaks to the relationships between stereotype threat and academic performance, and race-based psychosocial variables and academic performance, little research thus far has investigated these variables simultaneously. To address this gap in the literature, the current study examined the impact of a negative stereotype induction on persuasive writing performance and post-task self-perceptions of academic performance in a sample of Black, White, and Hispanic undergraduate students. Unique to the current study is an additional investigation which reviewed the role racial/ethnic centrality plays in the relationship between stereotype threat and writing performance. A researcher generated measure of persuasive writing was administered to assess writing skills, and was scored based on a holistic quality scale with reported efficacy in the literature. Racial/ethnic centrality was assessed via the Multidimensional Inventory of Black Identity, whereas post-task perceptions of academic ability were garnered via a survey used in prior stereotype threat research. Participants were randomly assigned to either a stereotype induced or stereotype not induced condition, and completed study measures either in person, or online. Findings were not indicative of statistically significant differences in persuasive writing scores across experimental conditions; however, race/ethnic and gender differences were noted. Furthermore, Black participants in the stereotype induced condition were found to report more negative self-perceptions of writing ability. Racial/ethnic differences in racial/ethnic centrality were found, with Black and Hispanic participants self-reporting higher racial/ethnic centrality when compared to their White peers. Lastly, a statistically significant interaction effect for racial/ethnic identity by racial/ethnic centrality by stereotype condition was found for persuasive writing performance.
Periodic Orbit theory for Resonant Tunneling Diodes : comparison with quantum and experimental results

description: We investigate whether the quantal and experimental amplitudes of current oscillations of Resonant Tunneling Diodes in tilted fields are obtainable from Periodic Orbit (PO) theories by considering recently proposed PO approaches. We show, for the first time, that accurate amplitudes and frequency shifts for the current oscillations (typically to within a few %) can be obtained from a simple analytical formula both in the stable (torus-quantization) limit and the unstable regimes of the experiments which are dominated by isolated PO's. But we find that the PO approach does not describe quantitatively the dynamically interesting intermediate experimental regimes which appear to be dominated by contributions from complex orbits and multiple non-isolated PO's. We conclude that these regimes will not easily be described by the usual PO approach, even with simple normal forms.

Supersymmetric Seesaw without Singlet Neutrinos: Neutrino Masses and Lepton-Flavour Violation
Creators: name: Rossi, Anna
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We consider the supersymmetric seesaw mechanism induced by the exchange of heavy SU(2)_W triplet states, rather than `right-handed' neutrino singlets, to generate neutrino masses. We show that in this scenario the neutrino flavour structure tested at low-energy in the atmospheric and solar neutrino experiments is directly inherited from the neutrino Yukawa couplings to the triplets. This allows us to predict the ratio of the tau --> mu gamma (or tau --> e gamma) and mu --> e gamma decay rates in terms of the low-energy neutrino parameters. Moreover, once the model is embedded in a grand unified model, quark-flavour violation can be linked to lepton-flavour violation.

Polarisation of high energy gamma-rays after scattering

description: The polarisation of sunlight after scattering off the atmosphere was first described by Chandrasekhar using a geometrical description of Rayleigh interactions. Kosowsky later extended Chandrasekhar's formalism by using Quantum Field Theory (QFT) to describe the polarisation of the Cosmological Microwave Background radiation. Here we focus on a case that is rarely discussed in the literature, namely the polarisation of high energy radiation after scattering off particles. After demonstrating why the geometrical and low energy QFT approaches fail in this case, we establish the transport formalism that allows to describe the change of polarisation of high energy photons when they propagate through space or the atmosphere. We primarily focus on Compton interactions but our approach is general enough to describe e.g. the scattering of high energy photons off new particles or through new interactions. Finally we determine the conditions for a circularly polarised $γ$--ray signal to keep the same level of circular polarisation as it propagates through its environment.

description: The Quillayes sand tailings dam of Los Pelambres mine, a company owned by Antofagasta Minerals, is currently the highest sand tailings dam in Chile. The dam reached its final height of 198m in 2008 after 10 years of construction and operation. Early production at the Quillayes deposit was 114,000 tons of copper ore per day, and increased until finally reaching a production level of 140,000 tons in 2008. Existing topographical conditions provided a relatively low reservoir – dam ratio of 3:1. Therefore, a 70m-high starter embankment dam was needed, as well as high yearly increases in height of the dam during the first years. Most of the time, this required the total production of tailings be cycloned in order to produce the required dam raise sand volumes. During the design stage - originally envisaged for a maximum dam height of 175m - it was possible to test samples of sands obtained from the El Chinche tailings dam that was previously operated at the mine and designed for a much lower mine production level. This allowed for an extensive material testing program on the tailings sands, which included triaxial tests under high confining stresses, considering different densities and fines contents. The success of the Quillayes tailings dam formed the basis for the design and operation of the present tailings dam at the El Mauro mine, which has a tailings sand dam that will have a final height of 237m. This paper presents design considerations for the Quillayes tailings deposit, the water diversion scheme, and the sand tailings dam. Main construction and operational aspects as well as post-operational issues applicable to the deposit and tailings dam are also discussed.

Solitary waves in dispersive evolution equations of Whitham type with nonlinearities of mild regularity

description: We show existence of small solitary and periodic traveling-wave solutions in Sobolev spaces ${\mathrm{H}^s}$, ${ s > 0 }$, to a class of nonlinear, dispersive evolution equations of the form \begin{equation*} u_t + \left(Lu+ n(u)\right)_x = 0, \end{equation*} where the dispersion ${L}$ is a negative-order Fourier multiplier whose symbol is of KdV type at low frequencies and has integrable Fourier inverse ${ K }$ and the nonlinearity ${n}$ is inhomogeneous, locally Lipschitz and of superlinear growth at the origin. This generalises earlier work by Ehrnström, Groves & Wahlén on a class of equations which includes Whitham's model equation for surface gravity water waves featuring the exact linear dispersion relation. Tools involve constrained variational methods, Lions' concentration-compactness principle, a strong fractional chain rule for composition operators of low relative regularity, and a cut-off argument for ${n}$ which enables us to go below the typical ${s > \frac{1}{2}}$ regime. We also demonstrate that these solutions are either waves of elevation or waves of depression when ${ K }$ is nonnegative, and provide a nonexistence result when ${ n }$ is too strong.
