description: The identification and use of rock glaciers and related deposits as paleoclimatic indicators have been problematic to date because of an over-dependence on surface morphology as the basis for discrimination among forms. Accordingly, the objectives of this research are threefold: firstly, to distinguish between rock glaciers and similar alpine deposits by their sedimentological properties; secondly, to demonstrate the sequential development of a rock glacier-like feature through the Holocene; and, finally, to synthesize the above objectives in order to develop a model for the complex genesis of one such feature over time. Mount Assiniboine Provincial Park was chosen for study on the basis of the presence of a range of contrasting glacial and peri g lacial landforms within a relatively small area. Of these landforms, a rock glacierlike feature was investigated because pre-field and early field investigation suggested the possible complex manner in which it had evolved. Methods for the analysis of the surface morphology, relative degree of plant cover, sorting, and chemical and mechanical weathering were employed to establish the relative ages of the different areas of the landforrn. Mechanical, statistical and graphical techniques were used to analyze the nature and distribution of the sediments and, therefore, to infer the processes involved in the formation of the feature. The surface sediments of a talus slope, a complex ablation feature with certain rock glacier characteristi c s and an ice-cored mora ine were also sampled to provide basic sedimentological information for contrast with the rock glacier-like landform during the multiple discriminant analysis. The following are the primary conclusions of the study: four periods of Holocene glacial/periglacial activity apparently led to the present configuration of the rock glacier-like feature. The events appear to correspond with the three Neoglacial advances recognized in the Rocky Mountains of the United States (e.g., the Gannet Peak, the Audubon and the Triple Lakes) and the early Holocene Chateau Lake Louise Event of the Canadian Rockies. The two oldest zones of the feature seem to have been affected by rock glacier transport and deposition, whereas the younger areas were probably the scene of glacial erosion and deposition. It appears that rock glacier transport affects the nature and distribution of sediments differently than does the ablation of debris on ice-cored moraines, the former display ing crude sorting and orientation, while the latter apparently has more random distribution and orientation patterns.

description: We present the results of Monte Carlo simulation for a Kondo lattice model in which itinerant electrons interact with Ising spins with spin-ice type easy-axis anisotropy on a pyrochlore lattice. We demonstrate the efficiency of the truncated polynomial expansion algorithm, which enables a large scale simulation, in comparison with a conventional algorithm using the exact diagonalization. Computing the sublattice magnetization, we show the convergence of the data with increasing the number of polynomials and truncation distance.

The acoustic radiation force on a spherical thermoviscous particle in a thermoviscous fluid including scattering and microstreaming

description: We derive general analytical expressions for the time-averaged acoustic radiation force on a small spherical particle suspended in a fluid and located in an axisymmetric incident acoustic wave. We treat the cases of the particle being either an elastic solid or a fluid particle. The effects of particle vibrations, acoustic scattering, acoustic microstreaming, heat conduction, and temperature-dependent fluid viscosity are all included in the theory. Acoustic streaming inside the particle is also taken into account for the case of a fluid particle. No restrictions are placed on the widths of the viscous and thermal boundary layers relative to the particle radius. We compare the resulting acoustic radiation force with that obtained from previous theories in the literature, and we identify limits, where the theories agree, and specific cases of particle and fluid materials, where qualitative or significant quantitative deviations between the theories arise.

Universal values, coping strategies, and motive images of astronauts at the International Space Station
Creators: name: Brcic, Jelena
Publisher: name: University of British Columbia
Year: 2009

description: Value hierarchies, coping patterns, and motivations of International Space Station (ISS) astronauts were examined in the present set of studies. Thematic content analysis was applied for references to above psychosocial markers in narratives (media interviews, journals, and oral histories) of 46 astronauts from the ISS expeditions. Results revealed that the five most mentioned universal values were identified as Achievement, Security, Benevolence, Universalism, and Self Direction. In regards to coping strategies, astronauts are more likely to use problem-oriented than emotion-oriented strategies. The top three coping strategies astronauts relied on were Seeking Social Support, Planful Problem Solving, and reference to Luck. In addition, astronauts were most likely to seek support in the form of personal information from their crew and ground control. Astronauts were most likely to be motivated by Achievement followed by Affiliation and Power. The role of leadership aboard the station was also examined. It was concluded that commanders were most likely assuming the supportive leadership role. The findings have important implications in understanding crew relations prior to and during the mission.

description: We describe a new method to search for metal-poor candidates from the Hamburg/ESO objective-prism survey (HES) based on identifying stars with apparently strong CH G-band strengths for their colors. The hypothesis we exploit is that large over-abundances of carbon are common among metal-poor stars. The selection was made by considering two line indices in the 4300A region, applied directly to the low-resolution prism spectra. This work also extends a previously published method by adding bright sources to the sample. The spectra of these stars suffer from saturation effects, compromising the index calculations and leading to an undersampling of the brighter candidates. Visual inspection and classification of the spectra from the HES plates yielded a list of 5,288 new metal-poor candidates, which are presently being used as targets for medium-resolution spectroscopic follow-up. Estimates of the stellar atmospheric parameters, as well as carbon abundances, are now available for 117 of the first candidates, based on follow-up medium-resolution spectra obtained with the SOAR 4.1m and Gemini 8m telescopes. We demonstrate that our new method improves the metal-poor star fractions found by our pilot study by up to a factor of three in the same magnitude range, as compared with our pilot study based on only one CH G-band index. Our selection scheme obtained roughly a 40% success rate for identification of stars with [Fe/H] < -1.0; the primary contaminant is late-type stars with near solar abundances and, often, emission line cores that filled in the CaII K line on the prism spectrum. Because the selection is based on carbon, we greatly increase the numbers of known CEMP stars from the HES with intermediate metallicities -2.0 < [Fe/H] < -1.0, which previous survey efforts undersampled. There are eight newly discovered stars with [Fe/H] < -3.0 in our sample, including two with [Fe/H] < -3.5.

description: The temperature dependence of the chiral condensate in isospin-symmetric nuclear matter at varying baryon density is investigated using thermal in-medium chiral effective field theory. This framework provides a realistic approach to the thermodynamics of the correlated nuclear many-body system and permits calculating systematically the pion-mass dependence of the free energy per particle. One- and two-pion exchange processes, $Δ(1232)$-isobar excitations, Pauli blocking corrections and three-body correlations are treated up to and including three loops in the expansion of the free energy density. It is found that nuclear matter remains in the Nambu-Goldstone phase with spontaneously broken chiral symmetry in the temperature range $T\lesssim 100\,$MeV and at baryon densities at least up to about twice the density of normal nuclear matter, $2ρ_0 \simeq 0.3\, $fm$^{-3}$. Effects of the nuclear liquid-gas phase transition on the chiral condensate at low temperatures are also discussed.

description: Airway-related quantitative imaging biomarkers (QIB) are crucial for examination, diagnosis, and prognosis in lung diseases, while the manual delineation of airway structures is unduly burdensome [1, 2]. Several efforts have been made to improve the performance of automatic airway modelling [3-7]; however, current datasets only focus on
 diseases that have minor tracheal changes and do not incorporate complex pulmonary diseases. For instance, the honeycombing within the lung tissue in patients with fibrotic lung disease makes the annotation much more complicated and error-prone. To bridge this gap, 285 cases (235 from patients with fibrotic lung disease and 50 from patients with COVID-19) were collected and included in this challenge. The airway structures were meticulously annotated by three experienced radiologists. Competitors are first encouraged to devise automatic airway segmentation models with high robustness and generalization abilities, followed by exploring the most correlated QIB of mortality prediction. This challenge is an open-call challenge and new submissions are allowed after the conference. [1] T. M.

description: As established by scanning tunneling microscopy (STM) cleaved surfaces of the high temperature superconductor YBa$_2$Cu$_2$O$_{7-δ}$ develop charge density wave (CDW) modulations in the one-dimensional (1D) CuO chains. At the same time, no signatures of the CDW have been reported in the spectral function of the chain band previously studied by photoemission. We use soft X-ray angle resolved photoemission (SX-ARPES) to detect a chain-derived surface band that had not been detected in previous work. The $2k_\textup{F}$ for the new surface band is found to be 0.55\,Å$^{-1}$, which matches the wave vector of the CDW observed in direct space by STM. This reveals the relevance of the Fermi surface nesting for the formation of CDWs in the CuO chains in YBa$_2$Cu$_2$O$_{7-δ}$. In agreement with the short range nature of the CDW order the newly detected surface band exhibits a pseudogap, whose energy scale also corresponds to that observed by STM.

description: This paper addresses multi-user quantum key distribution networks, in which any two users can mutually exchange a secret key without trusting any other nodes. The same network also supports conventional classical communications by assigning two different wavelength bands to quantum and classical signals. Time and code division multiple access (CDMA) techniques, within a passive star network, are considered. In the case of CDMA, it turns out that the optimal performance is achieved at a unity code weight. A listen-before-send protocol is then proposed to improve secret key generation rates in this case. Finally, a hybrid setup with wavelength routers and passive optical networks, which can support a large number of users, is considered and analyzed.

description: We discuss in detail the dependence of the Gallium Anomaly on the detection cross section. We provide updated values of the size of the Gallium Anomaly and find that its significance is larger than about $5σ$ for all the detection cross section models. We discuss the dependence of the Gallium Anomaly on the assumed value of the half life of ${}^{71}\text{Ge}$, which determines the cross sections of the transitions from the ground state of ${}^{71}\text{Ga}$ to the ground state of ${}^{71}\text{Ge}$. We show that a value of the ${}^{71}\text{Ge}$ half life which is larger than the standard one can reduce or even solve the Gallium Anomaly. Considering the short-baseline neutrino oscillation interpretation of the Gallium Anomaly, we show that a value of the ${}^{71}\text{Ge}$ half life which is larger than the standard one can reduce the tension with the results of other experiments. Since the standard value of the ${}^{71}\text{Ge}$ half life was measured in 1985, we advocate the importance of new measurements with modern technique and apparatus for a better assessment of the Gallium Anomaly.

description: Bipolar molecular outflows have been observed and studied extensively in the past, but some recent observations of periodic variations in maser intensity pose new challenges. Even quasi-periodic maser flares have been observed and reported in the literature. Motivated by these data, we have tried to study situations in binary systems with specific attention to the two observed features, i.e., the bipolar flows and the variabilities in the maser intensity. We have studied the evolution of spherically symmetric wind from one of the bodies in the binary system, in the plane of the binary. Our approach includes the analytical study of rotating flows with numerical computation of streamlines of fluid particles using PLUTO code. We present the results of our findings assuming simple configurations, and discuss the implications.

description: We study two-dimensional (2D) Dirac fermions in the presence of a periodic mass term alternating between positive and negative values along one direction. This scenario could be realized for a graphene monolayer or for the surface states of topological insulators. The low-energy physics is governed by chiral Jackiw-Rebbi modes propagating along zero-mass lines, with the energy dispersion of the Bloch states given by an anisotropic Dirac cone. By means of the transfer matrix approach, we obtain exact results for a piece-wise constant mass superlattice. On top of Bloch states, two different classes of boundary and/or interface modes can exist in a finite-size geometry or in a nonuniform electrostatic potential, respectively. We compute the dispersion relation for both types of boundary and interface modes, which originate either from states close to the superlattice Brillouin zone (BZ) center or, via a Lifshitz transition, from states near the BZ boundary. In the presence of a potential step, we predict that the interface modes, the Bloch wave functions, and the electrical conductance will sensitively depend on the step position relative to the mass superlattice.

Optimisation of ITER Nb3Sn CICCs for coupling loss, transverse electromagnetic load and axial thermal contraction

description: The ITER cable-in-conduit conductors (CICCs) are built up from sub-cable bundles, wound in different stages, which are twisted to counter coupling loss caused by time-changing external magnet fields. The selection of the twist pitch lengths has major implications for the performance of the cable in the case of strain sensitive superconductors, i.e. Nb3Sn, as the electromagnetic and thermal contraction loads are large but also for the heat load from the AC coupling loss. Reduction of the transverse load and warm-up cool-down degradation can be reached by applying longer twist pitches in a particular sequence for the sub-stages, offering a large cable transverse stiffness, adequate axial flexibility and maximum allowed lateral strand support. Analysis of short sample (TF conductor) data reveals that increasing the twist pitch can lead to a gain of the effective axial compressive strain of more than 0.3 % with practically no degradation from bending. For reduction of the coupling loss, specific choices of the cabling twist sequence are needed with the aim to minimize the area of linked strands and bundles that are coupled and form loops with the applied changing magnetic field, instead of simply avoiding longer pitches. In addition we recommend increasing the wrap coverage of the CS conductor from 50 % to at least 70 %. The models predict significant improvement against strain sensitivity and substantial decrease of the AC coupling loss in Nb3Sn CICCs, but also for NbTi CICCs minimization of the coupling loss can be achieved. Although the success of long pitches to transverse load degradation was already demonstrated, the prediction of the combination with low coupling loss needs to be validated by a short sample test.

Range wars : ranching and pest eradication on British Columbia's Interior Plateau
Creators: name: Thistle, John
Publisher: name: University of British Columbia
Year: 2009

description: Range Wars examines the environmental history of pest eradication in western North American grasslands in the late 19th and 20th centuries. Using British Columbia as a case study, the dissertation examines two closely related wars waged by ranchers and range managers against creatures they considered pests. In the first part of the study the analysis focuses on the ecological problem of grasshopper plagues and the ways in which a campaign organized to eradicate them worked to expose and exacerbate economic divisions among immigrant ranchers. Next, the study recounts a war with 'wild horses' that also served to dispossess indigenous people and discredit their competing claims to to land. Both wars aimed to accommodate cattle in increasingly degraded grasslands but the problem of range degradation went largely unsolved. By focusing on the broader social and ecological dimensions of pest eradication the study provides new perspective on North America's environmental past.

description: We propose a broad class of $d$-dimensional conformal field theories of $SU(N)$ adjoint scalar fields generalising the 4$d$ Fishnet CFT (FCFT) discovered by Ö. Gürdogan and one of the authors as a special limit of $γ$-deformed $\mathcal{N}=4$ SYM theory. In the planar $N\to\infty $ limit the FCFTs are dominated by the ``fishnet" planar Feynman graphs. These graphs are explicitly integrable, as was shown long ago by A. Zamolodchikov. The Zamolodchikov's construction, based on the dual Baxter lattice (straight lines on the plane intersecting at arbitrary slopes) and the star-triangle identities, can serve as a ``loom" for ``weaving" the Feynman graphs of these FCFTs, with certain types of propagators, at any $d$. The Baxter lattice with $M$ different slopes and any number of lines parallel to those, generates an FCFT consisting of $M(M-1)$ fields and a certain number of chiral vertices of different valences with distinguished couplings. These non-unitary, logarithmic CFTs enjoy certain reality properties for their spectrum due to a symmetry similar to the PT-invariance of non-hermitian hamiltonians proposed by C. Bender. We discuss in more detail the theories generated by a loom with $M=2,3,4$, and the generalisation of the loom FCFTs for spinning fields in 4$d$.

Bulk reconstruction of AdS$_{d+1}$ metrics and developing kinematic space

description: The metrics of the global, Poincaré, and Rindler AdS$_{d+1}$ are explicitly reconstructed with given lightcone cuts. We first compute the metric up to a conformal factor with the lightcone cuts method introduced by Engelhardt and Horowitz. While a general prescription to determine the conformal factor is not known, we recover the factor by identifying the causal information surfaces from the lightcone cuts and finding that they are minimal. In addition, we propose a new type of kinematic space as the space of minimal surfaces in AdS$_{d+1}$, where a metric is introduced as a generalization of the case of $d=2$. This metric defines the set of bulk points, which is equivalent to that of lightcone cuts. Some other properties are also studied towards establishing a reconstruction procedure for general bulk metrics.

description: An enhanced concentration of 60Fe was found in a deep ocean's crust in 2004 in a layer corresponding to an age of ~2 Myr. The confirmation of this signal in terrestrial archives as supernova-induced and detection of other supernova-produced radionuclides is of great interest. We have identified two suitable marine sediment cores from the South Australian Basin and estimated the intensity of a possible signal of the supernova-produced radionuclides 26Al, 53Mn, 60Fe and the pure r-process element 244Pu in these cores. A finding of these radionuclides in a sediment core might allow to improve the time resolution of the signal and thus to link the signal to a supernova event in the solar vicinity ~2 Myr ago. Furthermore, it gives an insight on nucleosynthesis scenarios in massive stars, the condensation into dust grains and transport mechanisms from the supernova shell into the solar system.

description: A radial velocity study of the cataclysmic variable ES Dra (PG 1524+622) is presented. ES Dra is found to have an orbital period of 0.17660 \pm 0.00006 d (4.2384 \pm 0.0014 h). The mass-losing secondary star of ES Dra is detectable in the spectrum, and it has a spectral type of M2 \pm 1. From this, we estimate the absolute magnitude of ES Dra during our spectroscopic observations to have been MR = 6.5 \pm 0.5, and its distance to be 720 \pm 150 pc. The long-term light curve of ES Dra compiled by the American Association of Variable Star Observers (AAVSO) shows that ES Dra is a Z Cam star, which between 1995 and 2009 spent most of its time in standstill.

description: In this paper, two fatigue lifetime prediction models are tested on TiAl intermetallic using results from uniaxial low-cycle fatigue tests. Both assessments are based on dissipated energy but one of them considers a hydrostatic pressure correction. This work allows to confirm, on this kind of material, the linear nature, already noticed on silicon molybdenum cast iron, TiNi shape memory alloy and 304L stainless steel, of dissipated energy, corrected or not with hydrostatic pressure, according to the number of cycles to failure. This study also highlights that, firstly, the dissipated energy model is here more adequate to estimate low-cycle fatigue life and that, secondly, intrinsic parameters like microstructure as well as extrinsic parameters like temperature or strain ratio have an impact on prediction results.

description: Cooling and Entanglement in optomechanical systems coupled through radiation pressure and photothermal force is studied. To develop the photothermal model, we derive an expression for deformation constant of the force. Exploiting linearized quantum Langevin equations we investigate dynamics of such systems. According to our analysis, in addition to separate action of radiation pressure and photothermal force, their cross correlation effect plays an important role in dynamics of the system. We also achieve an exact relation for the phonon number of the mechanical resonator in such systems, and then we derive an analytical expression for it at weak coupling limit. At strong coupling regime, we show that utilizing the photothermal pressure makes the ground state cooling more approachable. The effect of photothermal force on the optomechanical entanglement is investigated in detail. According to our exact numerical and approximate analytical studies, even though the photothermal force is naturally a dissipative force, it can improve the optomechanical entanglement both quantitatively and qualitatively.

Hydro-system related mortality and in-lake behaviour of migrating adult sockeye salmon in the Seton-Anderson Watershed, British Columbia
Creators: name: Roscoe, David William
Publisher: name: University of British Columbia
Year: 2009

description: Pacific salmon carry out long distance spawning migrations from ocean feeding grounds to natal freshwater streams. Because many salmon rivers are dammed, fishways are required to enable individuals to pass through dams and reach upstream spawning areas. However, many fishways are ineffective, preventing or delaying upstream passage, suggesting a need to monitor and evaluate these facilities. I conducted a literature review of studies evaluating the effectiveness of fishways to assess what taxa and life-stages have been studied, the questions asked during evaluation, and how these varied by time or geographic location. The majority of studies focused on adult fishes (68%) and the order Salmoniformes (58%). Many studies evaluated exogenous mechanisms of passage failure, such as environmental or structural factors (69%). Few studies examined endogenous (i.e. physiological) factors or post-passage consequences, information that is necessary to understand passage failure and inform mitigation strategies. A field study was carried out to evaluate the impact of a dam and fishway on the spawning migrations of sockeye salmon in the Seton-Anderson watershed in British Columbia. I used acoustic telemetry, non-lethal biopsies, and an experimental approach, releasing fish either up- or down-stream of the dam and comparing behaviour and mortality between the two groups. Fishway passage efficiency was 80% and most failure was associated with failing to locate the entrance. Attraction to the fishway entrance varied with water discharge volume from the dam, with the longest delays and highest failure rate at the highest discharge. Fish released downstream of the dam suffered higher mortality in lakes upstream of the fishway (27%) compared to fish released downstream of the dam (7%), suggesting post-passage consequences that reduce survival. Sockeye migrating through two thermally stratified lakes upstream of the dam were used as models to investigate the hypothesis that temperatures selected by sockeye salmon are related to an individual’s reproductive status and energy reserves. As predicted, I found that energy and estradiol were positively related to thermal experience. Sockeye salmon with low energy and advanced reproductive status may have selected cooler temperatures in order to reduce metabolic energy expenditure and avoid over-ripening of gametes.
Exotic bound states of two baryons in light of chiral effective field theory

description: Baryon-baryon bound states in the strangeness S=-2, S=-3, and S=-4 sectors are considered. In particular, the dependence of the corresponding binding energies on the quark mass (or equivalently the pion mass) is explored in the framework of chiral effective field theory, in order to connect with current lattice QCD calculations. For a bound state in the Xi-Xi 1S0 channel, predicted by our leading-order effective field theory interaction, binding energies are inferred that are roughly in line with a recent lattice QCD result at meson and baryon masses that correspond to those in the lattice simulation. With regard to the so-called H-dibaryon it is shown that the SU(3) breaking effects induced by the differences of the pertinent two-baryon thresholds (Lambda-Lambda, Xi-N, Sigma-Sigma) have a very pronounced impact on its binding energy. A bound H-dibaryon as found in two lattice calculations could be shifted above the Lambda-Lambda or even above the Xi-N threshold for physical masses of the involved baryons.

description: We present a computational approach to simulate local contrast observed in Field Ion Microscopy (FIM). It is based on density-functional theory utilizing the Tersoff-Hamann approach as done in Scanning Tunneling Microscopy (STM). A key requirement is the highly accurate computation of the surface states' wave-function tails. To refine the Kohn-Sham states from standard iterative global solvers we introduce and discuss the EXtrapolation of Tails via Reverse integration Algorithm (EXTRA). The decaying tails are obtained by reverse integration (from outside in) using a Numerov-like algorithm. The starting conditions are then iteratively adapted to match the values of plane-wave Kohn-Sham wave functions close to the surface. We demonstrate the performance of the proposed algorithm by analysing and showing the chemical contrast for Ta at Ni surface.

description: We study an upper bound on masses of additional scalar bosons from the electroweak precision data and theoretical constraints such as perturbative unitarity and vacuum stability in the two Higgs doublet model taking account of recent Higgs boson search results. If the mass of the Standard-Model-like Higgs boson is rather heavy and is outside the allowed region by the electroweak precision data, such a discrepancy should be compensated by contributions from the additional scalar bosons. We show the upper bound on masses of the additional scalar bosons to be about 2 $(1)$ TeV for the mass of the Standard-Model-like Higgs boson to be 240 $(500)$ GeV.

Late Wisconsin ice movements and deglaciation: in the N.E. Porcupine Hills area, Alberta

description: The study of a 1476 km2 area located in the N.E. Porcupine Hills of Southwest Alberta, has provided most evidence for the movement and retreat of two Late Wisconsinan ice masses; the hybrid Marguerite (western) and Lochend (eastern) ice sheets. Although most evidence is given for the last glaciation, information is cited which relates to the earlier eastern Labuma and Maunsell advances of glacial Events Three and Two age respectively. No deposits from earlier western incursions of ice have been found, though it is known from mapping in an adjacent area to the west (Waters, 1975) that such advances entered that area. _x000D_ Evidence relating to the Labuma advance consists of the high level igneolis and metamorphic erratics. Maunsell deposits are much more coherent and may be found in a small zone in the southwest portion of the area. Hybrid Marguerite till displays mixed characteristics, though on the basis of pebble lithology it can easily be differentiated from the eastern tills in the area. The hybrid Marguerite glacier undoubtedly assimilated foreign eastern material as it flowed southwards over areas previously traversed by Laurentide advances. It was deflected southwards by the Lochend ice sheet which lay to the east of the mountains. Laboratory analyses confirm the eastern origin of the Lochend till. Both ice masses are considered to have been coeval. _x000D_ During deglaciation, which was effected by both ice stagnation and orderly re treat, a large proglacial lake (Lake Eden) was impounded in the area for which two still-stands have been recognized. An efficient system of meltwater channels formed at this time as the lake was drained. From 14c dates given by various researchers (e.g. Harris and Boydell, 1972) the area most probably became free of ice during the very early Holocene.
