Volcanostratigraphy, age and geologic setting of the Lower-Middle Jurassic Upper Hazelton Group, west-central British Columbia
Creators: name: Gordee, Sarah Marie
Publisher: name: University of British Columbia
Year: 2010

description: Lower and Middle Jurassic Hazelton Group rocks on the southwest margin of the Stikine Terrane (Stikinia) of the Canadian Cordillera are part of a widespread Early-Middle Jurassic arc assemblage. Upper Hazelton Group volcano-sedimentary strata host the world class, precious metal-enriched, polymetallic Eskay Creek volcanogenic massive sulphide (VMS) deposit in northwest Stikinia, as well as a number of epithermal and porphyry deposits in associated subvolcanic intrusions throughout central and northern Stikinia. Large segments of Hazelton Group strata are understudied, despite significant mineral potential. In southwest Stikinia, upper Hazelton Group strata are in part coeval with volcano-sedimentary strata that host the Eskay Creek deposit. The lithologic sequence in southwest Stikinia consists of late Early Jurassic mafic volcanic centre(s) overlain by a Middle Jurassic, sequence of volcanic vent-proximal, felsic volcanic strata, and associated reworked volcanic material. Volcanic textures, sedimentary structures and fossils together indicate dominantly shallow submarine deposition. Lithogeochemical studies indicate a normal, subduction-related affinity for Hazelton Group strata in southwest Stikinia, which contrasts with a more primitive, rift-related(?) affinity for the strata in the Eskay Creek VMS district in northwest Stikinia. Hazelton Group rocks in the Eskay Creek region and coeval rocks in southwest Stikinia were probably deposited within a broad submarine basin in the back-arc region of a Middle Jurassic oceanic island arc. Rocks of the Eskay Creek VMS district were probably deposited in a localised back-arc rift in a relatively deeper marine setting. Despite differences in the depositional environment and tectonic setting of the two regions, volcano-sedimentary sequences in southwest Stikinia demonstrate significant potential for contained VMS mineralisation.
Stochastic Fermi Acceleration of sub-Relativistic Electrons and Its Role in Impulsive Solar Flares

description: We reexamine stochastic Fermi acceleration (STFA) in the low energy (Newtonian) regime in the context of solar flares. The particle energization rate depends a dispersive term and a coherent gain term. The energy dependence of pitch angle scattering is important for determining the electron energy spectrum. For scattering by whistler wave turbulence, STFA produces a quasi-thermal spectrum. A second well-constrained scattering mechanism is needed for STFA to match the observed 10-100keV non-thermal spectrum. We suggest that STFA most plausibly acts as phase one of a two phase particle acceleration engine in impulsive flares: STFA can match the thermal spectrum below 10kev, and possibly the power law spectrum between 10 and 100keV, given the proper pitch angle scattering. However, a second phase, such as shock acceleration at loop tops, is likely required to match the spectrum above the observed knee at 100keV. Understanding this knee, if it survives further observations, is tricky.

Subjects: Resource /Energy Economics and Policy

description: Markets for endangered species potentially generate incentives for both legal supply and poaching. To deter poaching, governments can spend on enforcement or increase legal harvesting to reduce the return from poaching. A leader–follower commitment game is developed to examine these choices in the presence of illegal harvesting and the resulting impacts on species stocks. In addition, current trade restrictions imposed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora are examined. With Cournot conjectures among poachers, the model details the subgame perfect equilibrium interactions between poaching levels, enforcement and legal harvesting.

description: We present the KMOS-CLASH (K-CLASH) survey, a K-band Multi-Object Spectrograph (KMOS) survey of the spatially-resolved gas properties and kinematics of 191 (predominantly blue) H$α$-detected galaxies at $0.2 \lesssim z \lesssim 0.6$ in field and cluster environments. K-CLASH targets galaxies in four Cluster Lensing And Supernova survey with Hubble (CLASH) fields in the KMOS $IZ$-band, over $7'$ radius ($\approx2$-$3$ Mpc) fields-of-view. K-CLASH aims to study the transition of star-forming galaxies from turbulent, highly star-forming disc-like and peculiar systems at $z\approx1$-$3$, to the comparatively quiescent, ordered late-type galaxies at $z\approx0$, and to examine the role of clusters in the build-up of the red sequence since $z\approx1$. In this paper, we describe the K-CLASH survey, present the sample, and provide an overview of the K-CLASH galaxy properties. We demonstrate that our sample comprises star-forming galaxies typical of their stellar masses and epochs, residing both in field and cluster environments. We conclude K-CLASH provides an ideal sample to bridge the gap between existing large integral-field spectroscopy surveys at higher and lower redshifts. We find that star-forming K-CLASH cluster galaxies at intermediate redshifts have systematically lower stellar masses than their star-forming counterparts in the field, hinting at possible "downsizing" scenarios of galaxy growth in clusters at these epochs. We measure no difference between the star-formation rates of H$α$-detected, star-forming galaxies in either environment after accounting for stellar mass, suggesting that cluster quenching occurs very rapidly during the epochs probed by K-CLASH, or that star-forming K-CLASH galaxies in clusters have only recently arrived there, with insufficient time elapsed for quenching to have occured.

description: In order to explain recent experiments reporting a motion of magnetic domain walls (DW) in nanowires carrying a current, we propose a modification of the spin transfer torque term in the Landau-Lifchitz-Gilbert equation. We show that it explains, with reasonable parameters, the measured DW velocities as well as the variation of DW propagation field under current. We also introduce coercivity by considering rough wires. This leads to a finite DW propagation field and finite threshold current for DW propagation, hence we conclude that threshold currents are extrinsic. Some possible models that support this new term are discussed.

description: The present paper demonstrates that treating multidestination trips (MDT) as single‐destination trips does not involve any systematic upward or downward bias in consumer surplus (CS) estimates because the direct negative effect of a price increase (treating MDT as a single‐destination trip) is offset by a shift in the estimated demand curve. Still, ignoring MDT can greatly underestimate or overestimate the CS. In addition, we demonstrate that there is a sound theoretical basis for using preference information for allocating travel costs between different sites included in the MDT package. A novel extreme value approach is proposed, which does not require any overly restrictive assumptions about consumer preferences. This approach is applied to the zonal travel cost model of the Bellenden Ker National Park, Australia. Parametric and non‐parametric estimation techniques are used for calculating CS estimates, and the effects of different MDT treatments and estimation methods are compared.

description: Breaking waves entrain gas beneath the surface. The wave-breaking process energizes turbulent fluctuations that break bubbles in quick succession to generate a wide range of bubble sizes. Understanding this generation mechanism paves the way towards the development of predictive models for large-scale maritime and climate simulations. Garrett et al. (2000) suggested that super-Hinze-scale turbulent breakup transfers entrained gas from large to small bubble sizes in the manner of a cascade. We provide a theoretical basis for this bubble-mass cascade by appealing to how energy is transferred from large to small scales in the energy cascade central to single-phase turbulence theories. A bubble break-up cascade requires that break-up events predominantly transfer bubble mass from a certain bubble size to a slightly smaller size on average. This property is called locality. In this paper, we analytically quantify locality by extending the population balance equation in conservative form to derive the bubble-mass transfer rate from large to small sizes. Using our proposed measures of locality, we show that scalings relevant to turbulent bubbly flows, including those postulated by Garrett et al. (2000) and observed in breaking-wave experiments and simulations, are consistent with a strongly local transfer rate, where the influence of non-local contributions decays in a power-law fashion. These theoretical predictions are confirmed using numerical simulations in Part 2, revealing key physical aspects of the bubble break-up cascade phenomenology. Locality supports the universality of turbulent small-bubble break-up, which simplifies the development of subgrid-scale models to predict oceanic small-bubble statistics of practical importance.

description: A numerical investigation of two-laser photoassociation (PA) spectroscopy on spin-polarized metastable helium (He*) atoms is presented within the context of experimental observation of the least-bound energy level in the scattering potential and subsequent determination of the s-wave scattering length. Starting out from the model developed by Bohn and Julienne [Phys. Rev. A \textbf{60}, (1999) 414], PA rate coefficients are obtained as a function of the parameters of the two lasers. The rate coefficients are used to simulate one- and two-laser PA spectra. The results demonstrate the feasibility of a spectroscopic determination of the binding energy of the least-bound level. The simulated spectra may be used as a guideline when designing such an experiment, whereas the model may also be employed for fitting experimentally obtained PA spectra. In addition, the prospects for substantial modification of the He* scattering length by means of optical Feshbach resonances are considered. Several experimental issues relating to the numerical investigation presented here are discussed.

We vertex dimuons with invariant mass near the Z peak and study the decay length distribution. No evidence of a long-lived component is found, and cross-section limits are presented on a fourth generation quark model.

description: We investigate (non-relativistic) atomic systems interacting with quantum electromagnetic field (QEF). The resulting model describes spontaneous emission of light from a two-level atom surrounded by various initial states of the QEF. We assume, that the quantum field interacts with the atom via the standard, minimal-coupling Hamiltonian, with the $A^2$ term neglected. We also assume, that there will appear at most single excitations (photons). By conducting the analysis on a general level we allow for an arbitrary initial state of the QEF (which can be for instance: the vacuum, the ground state in a cavity, or the squeezed state). We derive a Volterra-type equation which governs the time evolution of the amplitude of the excited state. The two-point function of the initial state of the QEF, integrated with a combination of atomic wavefunctions, forms the kernel of this equation.

description: In strongly coupled supersymmetric SO(N_c) gauge theories with N_f-quarks for N_c-2<=N_f(<=3(N_c-2)/2), their low-energy physics can be described by Nambu-Goldstone superfields associated with dynamical flavor symmetry breaking, which should be compared with the absence of flavor symmetry breaking in the conventional description in terms of magnetic degrees of freedom. The presence of the flavor symmetry breaking is confirmed by the well-known instanton effects in SO(N_c) with N_f=N_c-2, which are also described by our proposed effective superpotential. For N_f>=N_c-1, our effective superpotentials utilize baryonic configurations as well as mesons composed of two quarks. The baryonic configurations are supplied by "diquarks" made of N_c-1 quarks for N_f=N_c-1 and by baryons composed of N_c quarks for N_c>=N_f. It is argued that our effective superpotentials exhibit the holomorphic decoupling property, the anomaly-matching property and correct description of instanton effects in SO(N_c) when N_f-N_c+2 quarks become massive if N_f>=N_c-1.

description: We consider the problem of stabilizing the coherence of a single qubit subject to Markovian decoherence, via the application of a control Hamiltonian, without any additional resources. In this case neither quantum error correction/avoidance, nor dynamical decoupling applies. We show that using tracking-control, i.e., the conditioning of the control field on the state of the qubit, it is possible to maintain coherence for finite time durations, until the control field diverges.

description: We demonstrate radio-frequency tuning of the energy of individual CdTe/ZnTe quantum dots (QDs) by Surface Acoustic Waves (SAWs). Despite the very weak piezoelectric coefficient of ZnTe, SAW in the GHz range can be launched on a ZnTe surface using interdigitated transducers deposited on a c-axis oriented ZnO layer grown on ZnTe containing CdTe QDs. The photoluminescence (PL) of individual QDs is used as a nanometer-scale sensor of the acoustic strain field. The energy of QDs is modulated by SAW in the GHz range and leads to characteristic broadening of time-integrated PL spectra. The dynamic modulation of the QD PL energy can also be detected in the time domain using phase-locked time domain spectroscopy. This technique is in particular used for monitoring complex local acoustic fields resulting from the superposition of two or more SAW pulses in a cavity. Under magnetic field, the dynamic spectral tuning of a single QD by SAW can be used to generate single photons with alternating circular polarization controlled in the GHz range.

description: This study evaluates seven irrigation systems for use in production of grain sorghum and corn. These systems are medium pressure center-pivot (MPCP), low pressure center-pivot (LPCP), low drift nozzle center-pivot (LDN) , low energy precision application center-pivot (LEPA), furrow flood (FF) , surge flood (SF), and subsurface drip (SD). After-tax net present value estimates from investing in and using each system over a 10-year period to produce grain sorghum and corn are compared. The surge flood system, has the highest net returns under typical conditions for irrigation of both grain sorghum and corn. The furrow flood system generates the next highest net returns for both crops, followed by the subsurface drip system. The medium pressure center-pivot system is the least profitable for both crops. Of the center-pivot systems, the low pressure system has the highest net return, but is followed very closely by the low drift nozzle system. The results of the sensitivity analysis indicate that the net return estimates and ranking of the subsurface drip system are very sensitive to the yield response to irrigation. Lower than average crop prices also have a substantial impact on the ranking of this system. The original investment cost is also an important determinant of its net return.
A 1D ocean mixing model of the Strait of Georgia : ecological responses to physical forcing
Creators: name: Collins, A. Kathleen
Publisher: name: University of British Columbia
Year: 2010

description: A coupled biophysical model of the Strait of Georgia, British Columbia, Canada has been developed and successfully predicts the timing of the spring phytoplankton bloom. The physical model is a one dimensional vertical mixing model that is forced with hourly winds, cloud fraction, air temperature, and humidity, daily hydrographic data, and initial profiles of temperature, salinity, and fluorescence. The physical model uses a K Profile Parameterization of the boundary layer, and includes local parameterizations for albedo, cloud filtering, light attenuation, heat and freshwater fluxes. The Fraser River is used to parameterize freshwater flux, horizontal advection, and upwelling. The biological model includes one phytoplankton class (microphytoplankton) and one nutrient source (nitrate). The coupled biophysical model was tested to determine what physical factors are controlling the arrival of the spring bloom. Wind was found to control the timing of the bloom arrival, with strong winds delaying the bloom and weak winds causing the bloom to arrive earlier. Solar irradiance had a small effect on the arrival time and freshwater input (primarily Fraser River discharge) was insignificant to the arrival time of the bloom.

description: In a recent survey of the stellar populations of LINERS and LINER/HII Transition Objects (TOs) we identified a numerous class of nuclei which stand out because of their conspicuous 10^8-9 yr populations. These objects were called ``Young-TOs'', since they all have TO-like emission line ratios. In this paper we investigate the radial variations of spectral properties in Low Luminosity AGN. Our analysis is based on high S/N, 3500-5500 A, long-slit spectra for 47 galaxies. The data probe distances of typically up to 850 pc from the nucleus with a resolution of ~ 100 pc and S/N ~ 30. Stellar population gradients are mapped by the radial profiles of absorption line equivalent widths and colours along the slit. These variations are further analyzed by means of a decomposition of each spectrum in terms of template galaxies representative of very young (<= 10^7 yr), intermediate age (10^8-9 yr) and old (10^10 yr) populations. Our main findings are: (1) Significant stellar population gradients are found almost exclusively in Young-TOs. (2) The intermediate age population of Young-TOs, although heavily concentrated in the nucleus, reaches distances of up to a few hundred pc. (3) Objects with predominantly old populations present spatially homogeneous spectra, be they LINERs or TOs. (4) Young-TOs have much more dust in their central regions than other LLAGN. (5) The B-band luminosities of the central

description: We report optical monitoring observations of 20 high-luminosity AGN, 12 of which are radio-quiet quasars (RQQs). Intra-night optical variability (INOV) was detected for 13 of the 20 objects, including 5 RQQs. The variations are distinctly stronger and more frequent for blazars than for the other AGN classes. By combining these data with results obtained earlier in our program, we have formed an enlarged sample consisting of 9 BL Lacs, 19 RQQs and 11 lobe-dominated radio-loud quasars. The moderate level of rapid optical variability found for both RQQs and radio lobe-dominated quasars argues against a direct link between INOV and radio-loudness. We supplemented the present observations of 3 BL Lacs with additional data from the literature. In this extended sample of 12 well observed BL Lacs, stronger INOV is found for the EGRET detected BL Lacs.

description: Hidden Markov chains are widely applied statistical models of stochastic processes, from fundamental physics and chemistry to finance, health, and artificial intelligence. The hidden Markov processes they generate are notoriously complicated, however, even if the chain is finite state: no finite expression for their Shannon entropy rate exists, as the set of their predictive features is generically infinite. As such, to date one cannot make general statements about how random they are nor how structured. Here, we address the first part of this challenge by showing how to efficiently and accurately calculate their entropy rates. We also show how this method gives the minimal set of infinite predictive features. A sequel addresses the challenge's second part on structure.

description: Observando los patrones de desplazamiento entre el lugar de residencia y el lugar de trabajo en 1115 municipios, se realiza un análisis jerárquico de conglomerados para identificar territorios con un alto nivel de interacción económica (Territorios Funcionales). A su vez, se identifica un gradiente rural-urbano de los territorios en Colombia que incluye desde territorios rurales profundos hasta regiones metropolitanas. Con un total de 438 Territorios Funcionales identificados, se describen las principales características económicas y socio-demográficas, mostrando tanto la tendencia entre los periodos 1993 y 2005, así como algunas diferencias de género. Finalmente, comparamos la definición “oficial” de rural-urbano con el gradiente identificado en este trabajo.

description: Este documento hace un diagnostico multidimensional de las brechas regionales que existen en Colombia a nivel departamental y de su persistencia en el tiempo. Así mismo se estudian las causas de la inequidad regional. La evidencia presentada sugiere que las diferencias institucionales de largo plazo explican las desigualdades regionales actuales. Para el diagnóstico se utiliza un conjunto amplio de variables socioeconómicas incluyendo variables de ingreso y actividad económica, variables de capital humano, medidas de pobreza y desigualdad, variables de comportamiento político, variables de aislamiento geográfico, y variables de esfuerzo o dependencia fiscal. El documento también revisa algunas experiencias internacionales exitosas en la disminución de brechas regionales y plantea algunas sugerencias de política pública para el caso colombiano.

description: El objetivo de este estudio es discutir alternativas de políticas públicas para aumentar el acceso a la tierra y el ingreso de la población rural. Para alcanzar este objetivo, el estudio aborda tres temas. Primero, el estudio describe la estructura de la propiedad rural en Colombia y discute alternativas para incrementar el acceso al uso de la tierra por parte de la población rural. Segundo, se discuten posibles relaciones entre la estructura de tenencia de la tierra, el bienestar de los hogares rurales y las decisiones de producción e inversión. Por último, el estudio describe las experiencias de programas de reformas agrarias en algunos países de América Latina y Colombia. El estudio encuentra que, además de una altísima concentración de la tierra, los mercados de arrendamiento de tierras en Colombia son casi inexistentes, por lo cual el acceso al uso de la tierra es bajo. En segundo lugar, el acceso al uso de la tierra y la formalidad en la propiedad están relacionados con mayores niveles de consumo e inversión productiva en los hogares rurales. Por último, pese a que el acceso a la tierra es determinante en el bienestar, el estudio concluye que programas complementarios, como crédito y asistencia técnica, son determinantes en el bienestar de la población rural.

description: El objetivo de este artículo es investigar la relación entre el conflicto armado y la producción agropecuaria de los pequeños productores colombianos. El efecto de la violencia se desagrega entre los impactos directos (choques violentos) e indirectos (presencia de grupos armados). Las estimaciones muestran que el efecto del conflicto trasciende los impactos directos, pues el control y la presencia de los grupos armados causan miedo e incertidumbre a los hogares, generando modificaciones en sus decisiones productivas. Los hogares que viven en veredas con una alta incidencia de la violencia asignan 19.3 puntos porcentuales menos a cultivos permanentes, 13.7 puntos porcentuales más a transitorios y 14.6 puntos porcentuales más a pastos. La presencia de grupos armados no está relacionada con la decisión de uso de la tierra para cultivos permanentes, pero sí con los transitorios y pastos. Hogares que viven en veredas en las cuales los grupos armados han estado presentes cuatro y seis años de presencia están relacionados con un mayor porcentaje de tierras asignado a pastos de 7.7 y 7.3 puntos porcentuales, respectivamente. Bajo conflicto armado, los hogares se dedican a cultivos de menor rentabilidad e inviertan menos en el predio, generando así menores ingresos. Así, las políticas públicas de posconflicto deben ir más allá de la reconstrucción y restitución de activos. Es fundamental generar condiciones favorables para reducir la incertidumbre, mejorar el imperio de la ley y fortalecer la confianza en el Estado.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Neuropeptide SF (NPSF) is a member of RFamide neuropeptides that play diverse roles in central nervous system. Little is know about the effects of NPSF on brain functions. Antidepressant-like effect of NPSF was studied in modified mice FST. NPSF showed the antidepressant-like effects by decreasing the immobility time and increasing the climbing and swimming time. Furthermore, the involvement of the adrenergic, serotonergic, cholinergic or dopaminergic receptors in the antidepressant-like effect of NPSF was studied in modified mice FST. Mice were pretreated with a non-selective α-adrenergic receptor antagonist phenoxybenzamine, a \b{eta}-adrenergic receptor antagonist, propranolol, a non-selective 5-HT2 serotonergic receptor antagonist, cyproheptadine, nonselective muscarinic acetylcholine receptor antagonist, atropine, or D2, D3, D4 dopamine receptor antagonist, haloperidol. The present results confirmed that the antidepressant-like effect of NPSF is mediated, at least in part, by an interaction of the α-adrenergic, 5-HT2 serotonergic, muscarinic acetylcholine receptors and D2, D3, D4 dopamine receptor in a modified mouse FST.

description: We provide the gauge-invariant expression for large-scale cosmic microwave background temperature fluctuations at second-order in perturbation theory. It enables to unambiguously define the nonlinearity parameter f_NL which is used by experimental collaborations to pin down the level of Non-Gaussianity in the temperature fluctuations. Furthermore, it contains a primordial term encoding all the information about the Non-Gaussianity generated at primordial epochs and about the mechanism which gave rise to cosmological perturbations, thus neatly disentangling the primordial contribution to Non-Gaussianity from the one caused by the post-inflationary evolution.

description: We construct and study rotating axion boson stars (RABSs). These are the spinning generalisations of the spherical gravitating solitons recently introduced in arXiv:1909.05515. RABSs are asymptotically flat, stationary, axially symmetric, everywhere regular solutions of the Einstein-Klein-Gordon theory, in the presence of a periodic scalar potential arising in models of axion-like particles. The potential is characterised by two parameters: the mass of the scalar field $m_a$ and the decay constant $f_a$. We present an overview of the solution space, for different values of $f_a$, and analyse some of their phenomenological properties. For large decay constants the solutions become identical to the standard spinning mini boson stars. For small decay constants, on the other hand, the solutions develop distinctive features. In particular, we analyse their compactness, the emergence of ergoregions, light rings and the distribution of stable and unstable equatorial timelike circular orbits, including the innermost stable circular orbit. We also establish the occurrence of violations of the strong energy condition for physical observers, for some RABSs. We observe some analogy between RABSs and spinning gravitating $Q$-balls.
