Air quality and visibility in southwestern British Columbia during forest fire smoke events
Creators: name: Keane, Jenna Christine
Publisher: name: University of British Columbia
Year: 2012

description: In recent years, the frequency of forest fires has been increasing in western North America. With an increase in forest fire activity, attention has been drawn to the negative effects forest fire smoke has on air quality and visibility. This study quantifies the relationship between smoke, air quality and visibility. Determining how much smoke produced by forest fires influences air quality and visibility will improve air quality forecasting. This study was conducted from 2007 through 2011 during the fire season (April - October) in southwestern British Columbia, focusing on the Georgia Basin airshed. A host of tools were used to determine how air quality and visibility were influenced by forest fire smoke. Satellite Fire Detection from National Oceanic and Atmospheric Administration (NOAA)’s, National Geophysical Data Centre(NDGC) was used to determine on which days during the four year period smoke was present in southwestern British Columbia. To determine where smoke particles were transported from, NOAA’s HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used. Backward trajectories were computed from Vancouver International Airport on days which smoke was present. PM₂.₅ (particles with a diameter less than 2.5 microns) and O₃ (ozone) concentrations were examined at twelve locations. Gases and aerosols produced by forest fires are known to degrade visibility. A semi-automated approach was used to calculate visibility using digital images. Southwestern British Columbia's air quality and visibility was negatively influenced by smoke. Up to 30% of summer days in the Georgia Basin airshed were influenced by smoke. The summer of 2009 experienced the most smoke days. Smoke and aerosol concentrations were largely influenced by dominating weather patterns. Two weather patterns dominate in the Georgia Basin airshed on smoke days. One pattern creates favourable conditions to produce forest fires and the other is likely to transport smoke from the interior of British Columbia into the Georgia Basin airshed. Concentrations of fine particulate matter increased on average by 5 µgm⁻³ and ozone increased by 7 ppb when smoke was present. Visual range (VR) decreased on average by 60 km and estimated extinction values increased during smoke events.

description: We study the effect of thermal fluctuations on the topological stability of chiral p-wave superconductors. We consider two models of superconductors: spinless and spinful with a focus on topological properties and Majorana zero-energy modes. We show that proliferation of vortex-antivortex pairs above the Kosterlitz-Thouless temperature T_KT drives the transition from a thermal Quantum Hall insulator to a thermal metal/insulator, and dramatically modifies the ground-state degeneracy splitting. Therefore, in order to utilize 2D chiral p-wave superconductors for topological quantum computing, the temperature should be much smaller than T_KT. Within the spinful chiral p-wave model, we also investigate the interplay between half-quantum vortices carrying Majorana zero-energy modes and full-quantum vortices having trivial topological charge, and discuss topological properties of half-quantum vortices in the background of proliferating full-quantum vortices.

description: Characters from medieval and Renaissance chivalric texts have been given tangible form through the centuries not only in operatic, melo-dramatic, theatrical and, more recently, cinematic adaptations, but also in popular performance traditions such as Sicilian puppet theater (opera dei pupi) and the folk operas (maggi epici) of the Tuscan-Emilian Apennines. This essay traces the reimagining of a sampling of non-Christian characters and non-European places from Matteo Maria Boiardo’s Orlando Innamorato and Ludovico Ariosto’s Orlando Furioso by a number of contemporary puppet theater and maggio companies. My contention is that an examination of select scenes available online, in conjunction with a close reading of the original episodes, may help students think more deeply about perennial issues addressed in the two poems—related to gender roles, the foreign and religious Other, violence, and political power—that continue to be relevant today.

description: The desire to stay connected to one another over large distances has guided decades of telepresence research. Most focuses on stationary solutions that can deliver high-fidelity telepresence experiences, but these are usually impractical for the wider population who cannot afford the necessary proprietary equipment or are unwilling to regress to non-mobile communication. In this paper we present Mobileportation, a nomadic telepresence prototype that takes advantage of recent developments in mobile technology to provide immersive experiences wherever the user desires by allowing for seamless transitions between ego- and exocentric views within a mutually shared three-dimensional environment. The results of a user study are also discussed that show Mobileportation's ability to induce a sense of presence within this environment and with the remote communication partner, as well as the potential of this platform for future telepresence research.

description: We present 3D adaptive mesh refinement MHD simulations of an isolated galaxy cluster that include injection of kinetic, thermal, and magnetic energy via a central active galactic nucleus (AGN) in order to study and evaluate the role that AGN may play in producing the observed cluster-wide magnetic fields. Using the MHD solver in FLASH 3.3, we compare several sub-resolution approaches to the evolution of AGN, specifically focusing on large-scale jet and bubble models. We examine the effects of magnetized outflows on the accretion history of the black hole and cluster thermodynamic properties, discuss the ability of various models to magnetize the cluster medium, and assess the sensitivity of these models to their underlying subgrid parameters. We find that magnetized jet-based models suffer a severe reduction in accretion rate compared to hydrodynamic jets; however, bubble models remain largely unaffected. While both jets and sporadically-placed bubbles have difficulty reproducing the observed strength and topology of cluster magnetic fields, models based on centrally-located bubbles come closest to observations. Finally, whereas jet models are relatively insensitive to changes in their subgrid parameters, the accretion rate and average magnetic field produced by the bubbles vary by as much as an order of magnitude depending on the grid resolution and accretion strength.

description: On March 24, 2014, the Columbia Global Policy Initiative hosted over forty academics, youth activists, policy-makers, practitioners, and civil society representatives at Columbia University in New York City for an in-depth discussion on the marginalization and inequality facing youth worldwide. The conference brought together the diverse experiences and research findings of individuals around the world on youth issues, which often do not have a policy space in which to interact. The issues included human rights and justice; political participation and decision-making; gender and health inequalities; and employment, education, and migration opportunities. Conference participants examined the topics in the context of youth development, empowerment, and equality within society. The event was co-sponsored by the Office of the UN Secretary-General’s Envoy on Youth. The event was followed by a high-level policy dialogue at the UN on March 25, 2014 with member-states, agencies, civil society, and youth representatives.
The $μν$SSM with an extra U(1)

description: The $μν$SSM solves the $μ$ problem of the MSSM and generates correct neutrino masses by simply using right-handed neutrinos. This mechanism implies that only dimensionless trilinear terms, breaking R-parity, are present in the superpotential. We present an extension of the $μν$SSM with an extra U(1) gauge symmetry. We use the extra U(1) charges of the matter fields to forbid the presence in the superpotential of renormalizable and non-renormalizable baryon number violating operators, the trilinear operator producing a domain wall problem, and bilinear operators such as the $μ$ term and the Majorana masses. We apply the anomaly cancellation conditions associated to the extra U(1), to constrain the values of the U(1) charges. We find that six assignments of the U(1) charges to the matter fields are viable, once extra matter is introduced. In particular, three generations of vector-like color triplets and $SU(2)_L$ doublets, as well as six Standard Model singlets are necessary. Electroweak symmetry breaking is viable in the model, with wide regions of the parameter space fulfilling the experimental constraints on the existence of a new gauge boson $Z'$. Neutrinos and the extra gaugino mix with the MSSM neutralinos, producing a generalized see-saw matrix that can reproduce the experimental results on neutrino masses. Finally, we have estimated the tree-level upper bound on the lightest Higgs mass, finding that it can be as large as about 120 GeV.

Exploring the interaction environment of blood cells : proteomic analysis of platelet releasate and platelet-monocyte interaction

Publisher: name: University of British Columbia

description: Platelet-monocyte aggregates circulating in the blood are found to play an important role in cardiovascular disease, the most common cause of death in Canada, and are now an established early marker of acute events. Upon stimulation, monocytes transmigrate across the endothelial layer into the intima where they take up oxidized low density lipoproteins (LDL) and differentiate into macrophages, and are then incorporated into atherosclerotic plaques. Upon plaque rupture, which accounts for the majority of fatal cardiovascular incidents, platelets are exposed to a variety of agonists such as collagen and mildly oxidized LDL. We used dimethyl labeling quantitative proteomics approach to determine the relative abundance of platelet releasate (Rel) proteins from platelets activated with thrombin, collagen or Lysophosphatidic acid (LPA; the most potent platelet activator found in mildly oxidized LDL). Using the different agonists led to releasates with unique protein compositions. In addition, we analyzed the relative abundance of protein in releasate free of microparticles (Rel-MP) when using the different agonists. Flow cytometry and proteomics studies showed that thrombin, collagen or LPA activated platelets not only produce different number of platelet microparticles (MP), but that these MP have different proteome profiles. We studied the effects of combining agonists by activating platelets with thrombin plus collagen or a subthreshold concentration of collagen plus LPA. Through biologic functional studies we saw that the Rel, Rel-MP or MP from the platelets activated with the different agonists lead to different degree of THP-1 cell migration. We added the contents released from thrombin activated platelets to a human monocytic cell line THP-1, in order to find the proteins which are responsible for THP-1 cell stimulation. Based on the increased expression of proteins such as integrin β1, we found that, adding platelet releasate induces a pro-inflammatory state in THP-1 cells and prime them for transmigration. Therefore, we have taken considerable strides towards uncovering the effect of platelet activation on monocyte protein expression. The findings may aid in discovery of drug targets for prevention of inappropriate platelet activation and platelet-monocyte aggregate formation, in order to dampen the effects of these events in contributing to cardiovascular disease.

description: Supermassive black holes exist in the centers of galaxies, including Milky Way, but there is no compelling theory of their formation. Furthermore, observations of quasars imply that supermassive black holes have already existed at some very high redshifts, suggesting the possibility of their primordial origin. In a class of well-motivated models, inflationary epoch could include two or more periods of inflation dominated by different scalar fields. The transition between such periods of inflation could enhance the spectrum of density perturbations on some specific scale, which could lead to formation of primordial black holes with a very narrow range of masses of the order of 10^5 solar masses. These primordial black holes could have provided the requisite seeds for the observed population of supermassive black holes.

description: Ten years after the Responsibility to Protect (RtoP) was unanimously adopted by the General Assembly in 2005, the international community is still faced with challenges of ensuring that genocide, crimes against humanity, war crimes, and ethnic cleansing are never again committed. In light of RtoP’s 10th anniversary and ongoing situations of mass atrocities around the world, the Columbia University Global Policy Initiative (CGPI) and the International Relations Research Center at the University of São Paulo (NUPRI) organized a two-day conference in April 2015 on Responsibility while Protecting: Implementation Mechanisms and the Future of the Responsibility to Protect. The conference brought together key academic, UN, and governmental voices. Ambassador Antonio de Aguiar Patriota, Permanent Representative of Brazil to the UN, and Dr. Jennifer Welsh, Special Adviser to the UN Secretary-General on the Responsibility to Protect, presented keynote speeches. Topics under consideration included the Brazilian concept of Responsibility while Protecting (RwP), what happened to RtoP after the 2011 Libya intervention, how RwP has changed RtoP, how we can improve effective implementation of RtoP, and finally what the future of RtoP and atrocity prevention holds. The conference’s three panels and two keynote speeches are detailed in the report as well as recommendations to improve understanding and implementation of atrocity prevention and response.

description: The robustness to different sources of error of the scheme for non-adiabatic holonomic gates proposed in [New J. Phys. {\bf 14}, 103035 (2012)] is investigated. Open system effects as well as errors in the driving fields are considered. It is found that the gates can be made error resilient by using sufficiently short pulses. The principal limit of how short the pulses can be made is given by the breakdown of the quasi-monochromatic approximation. A comparison with the resilience of adiabatic gates is carried out.

We show that constraints derived on the mass of the lightest h0 and the CP-odd A0 bosons from these searches are covering a broader fraction of the SUSY parameter space compared to searches for strongly interacting supersymmetric particle partners. We discuss the implications of a mass determination in the range 123 < Mh < 127 GeV, inspired by the intriguing hints reported by the ATLAS and CMS collaborations, as well as those of a non-observation of the lightest Higgs boson on MSSM scenarios not excluded at the end of 2012 by LHC and direct dark matter searches and their implications on LHC SUSY searches.

description: The Hodge numbers of generic elliptically fibered Calabi-Yau threefolds over toric base surfaces fill out the "shield" structure previously identified by Kreuzer and Skarke. The connectivity structure of these spaces and bounds on the Hodge numbers are illuminated by considerations from F-theory and the minimal model program. In particular, there is a rigorous bound on the Hodge number h_{21} <= 491 for any elliptically fibered Calabi-Yau threefold. The threefolds with the largest known Hodge numbers are associated with a sequence of blow-ups of toric bases beginning with the Hirzebruch surface F_{12} and ending with the toric base for the F-theory model with largest known gauge group.

description: The ability to resolve all processes which drive galaxy formation is one of the most fundamental goals in extragalactic astronomy. While star formation rates and the merger history are now measured with increasingly high certainty, the role of gas accretion from the intergalactic medium in supplying gas for star formation still remains largely unknown. We present in this paper indirect evidence for the accretion of gas into massive galaxies with initial stellar masses M_*>10^{11} M_sol and following the same merger adjusted co-moving number density at lower redshifts during the epoch 1.5 < z < 3, using results from the GOODS NICMOS Survey (GNS). We show that the measured gas mass fractions of these massive galaxies are inconsistent with the observed star formation history for the same galaxy population. We further demonstrate that this additional gas mass cannot be accounted for by cold gas delivered through minor and major mergers. We also consider the effects of gas outflows and gas recycling due to stellar evolution in these calculations. We argue that to sustain star formation at the observed rates there must be additional methods for increasing the cold gas mass, and that the likeliest method for establishing this supply of gas is by accretion from the intergalactic medium. We calculate that the average gas mass accretion rate into these massive galaxies between 1.5 < z < 3.0, is \dot{M} = 96+/-19 M_sol/yr after accounting for outflowing gas. We show that during this epoch, and for these very massive galaxies, 49+/-20% of baryonic mass assembly is a result of gas accretion and unresolved mergers. However, 66+/-20% of all star formation in this epoch is the result of gas accretion. This reveals that for the most massive galaxies at 1.5< z< 3 gas accretion is the dominant method for instigating new stellar mass assembly.

We find a qualitative agreement of the momentum resolved spectral function with angle-resolved photoemission spectra (ARPES) and former LDA+DMFT results. As a correction to LDA+DMFT, we observe more pronounced coherent peaks below the Fermi level, as indicated by ARPES experiments. In addition, we resolve the spectral functions in the ${\bf K}_{0}=(0,0,0)$ and ${\bf K}_{1}=(π,π,π)$ sectors of DCA, where band insulating and metallic phases coexist. Our approach can be applied to correlated compounds where not only local quantum fluctuations but also spatial fluctuations are important.

description: No abstracts are to be cited without prior reference to the author.Skates and rays (Rajidae) are vulnerable to overfishing because they are long-lived, slow-growing, late to mature, have protracted breeding cycles, and produce few young. Their large size, morphology, and aggregating behaviour also make them susceptible to capture in mixed demersal fisheries, and several species are also taken in targeted fisheries (using longline, gillnet, or trawl). The abundance and diversity of the skate community around the British Isles has changed over the course of the last 100 years. Some of the larger bodied species (e.g. white skate) have disappeared, while the smaller bodied species (e.g. spotted and thornback rays) have healthier populations. Research has also demonstrated that some species have very patchy distributions, and locally abundant species may be prone to depletion. Current management regulations for skates include a minimum landing size (in some inshore waters of England and Wales) and quotas, and some species are currently designated as prohibited species that cannot be retained. The efficacy of these and other potential measures is highly dependent on discard survival. Here we review the evolution of skate fisheries around the British Isles, discard and retention patterns of skates in selected UK fisheries, the recent introduction of management actions and discuss the merits of these and other potential measures in light of our current knowledge of discard survival.

description: No abstracts are to be cited without prior reference to the author.Porbeagle shark is one of the top marine predators in the North Atlantic. Little is known about its biology, abundance, or spatial ecology in this region, however. Here we present results on the migration and behaviour of three porbeagles tagged with archival pop-up tags off the northwest coast of Ireland that reveal important information on winter diving and migratory behaviour. One shark migrated over 2400 km to the northwest of Morocco, residing around the Bay of Biscay for approximately 30 days. The other two sharks remained more localized in offshelf regions around the Celtic Sea/Bay of Biscay and off western Ireland. The sharks occupied a broad vertical depth range (0–700 m) and temperature range (c. 9–17°C), with notable variations in diving behaviour between individuals. There were distinct day–night differences in depth distribution with each shark positioned predominantly higher in the water column during the night-time than during the day. Night-time depth distribution also appeared to be driven by the lunar cycle during broad-scale migration through oceanic waters. A 29.7-day cycle (a lunar ”month”) in night-time depth distribution was observed for one shark, and moon phase and night-time depth distribution was negatively correlated. Our results demonstrate that porbeagle sharks occupy and traverse regions of high fishing activity where they are potentially vulnerable to population depletion. Such large-scale movement outside the ICES area underlines the need for international coordination in assessment and management.

description: We present a new model for Ellipsoidal Variations Induced by a Low-Mass Companion, the EVIL-MC model. We employ several approximations appropriate for planetary systems to substantially increase the computational efficiency of our model relative to more general ellipsoidal variation models and improve upon the accuracy of simpler models. This new approach gives us a unique ability to rapidly and accurately determine planetary system parameters. We use the EVIL-MC model to analyze Kepler Quarter 0-2 (Q0-2) observations of the HAT-P-7 system, an F-type star orbited by a nearly Jupiter-mass companion. Our analysis corroborates previous estimates of the planet-star mass ratio q = (1.10 +/- 0.06) x 10^(-3), and we have revised the planet's dayside brightness temperature to 2680 +10/-20 K. We also find a large difference between the day- and nightside planetary flux, with little nightside emission. Preliminary dynamical+radiative modeling of the atmosphere indicates this result is qualitatively consistent with high altitude absorption of stellar heating. Similar analyses of Kepler and CoRoT photometry of other planets using EVIL-MC will play a key role in providing constraints on the properties of many extrasolar systems, especially given the limited resources for follow-up and characterization of these systems. However, as we highlight, there are important degeneracies between the contributions from ellipsoidal variations and planetary emission and reflection. Consequently, for many of the hottest and brightest Kepler and CoRoT planets, accurate estimates of the planetary emission and reflection, diagnostic of atmospheric heat budgets, will require accurate modeling of the photometric contribution from the stellar ellipsoidal variation.

description: In a number of recent experiments with microwave high quality superconducting coplanar waveguide (CPW) resonators an anomalously weak power dependence of the quality factor has been observed. We argue that this observation implies that the monochromatic radiation does not saturate the Two Level Systems (TLS) located at the interface oxide surfaces of the resonator and suggests the importance of their interactions. We estimate the microwave loss due to interacting TLS and show that the interactions between TLS lead to a drift of their energies that result in a much slower, logarithmic dependence of their absorption on the radiation power in agreement with the data.

description: It is well known that the vacuum in the Einstein gravity, which is linear in the Riemann curvature, is trivial in the critical (2+1=3) dimension because vacuum solution is flat. It turns out that this is true in general for any odd critical $d=2n+1$ dimension where $n$ is the degree of homogeneous polynomial in Riemann defining its higher order analogue whose trace is the nth order Lovelock polynomial. This is the "curvature" for nth order pure Lovelock gravity as the trace of its Bianchi derivative gives the corresponding analogue of the Einstein tensor \cite{bianchi}. Thus the vacuum in the pure Lovelock gravity is always trivial in the odd critical (2n+1) dimension which means it is pure Lovelock flat but it is not Riemann flat unless $n=1$ and then it describes a field of a global monopole. Further by adding Lambda we obtain the Lovelock analogue of the BTZ black hole.

Hypoxia tolerance in fishes : cardiorespiratory performance and metabolism
Creators: name: Speers-Roesch, Ben

description: Cardiac failure occurs in most vertebrates including humans following even short hypoxia exposure due to an inability to match cardiac energy demand to the limited energy supply. In contrast, hypoxia-tolerant ectothermic vertebrates show the remarkable ability to maintain cardiac energy balance and stable cardiac function during prolonged exposure to severe hypoxia (cardiac hypoxia tolerance, CHT). I investigated how CHT is achieved and its relationship to whole-animal hypoxia tolerance using measurements at multiple physiological levels in two study models: 1) tilapia, a hypoxia-tolerant teleost, and 2) a two-species comparison of elasmobranchs with different hypoxia tolerance. I tested the hypothesis that CHT depends upon the depression of cardiac power output (PO) (i.e., cardiac energy demand) to a level lower than the cardiac maximum glycolytic potential (MGP). All species showed a hypoxic PO depression via bradycardia and my work generally supports this hypothesis. However, in tilapia, hypoxic PO depression is not necessarily required to maintain cardiac energy balance, contrary to previous suggestions, because of an exceptionally high MGP. Thus, in certain species, PO depression may primarily benefit CHT by minimizing fuel use and waste production. I also tested the hypothesis that greater hypoxia tolerance is associated with enhanced hypoxic O₂ supply and consequently enhanced cardiovascular function (i.e., less PO depression and improved cardiac energy balance). My work on elasmobranchs supported this hypothesis and also suggested a role for strategic cardiac O₂ supply via O₂ sparing resulting from metabolic rate depression (MRD) in non-essential tissues. Finally, my work on elasmobranchs showed that critical oxygen tension (Pcrit) predicts hypoxic blood O₂ transport, supporting the use of Pcrit as an indicator of hypoxia tolerance. Next, I tested the hypothesis that hypoxic PO depression is associated with the depression of whole-animal O₂ consumption rate below Pcrit. I found that this occurred in all species, suggesting that modulation of peripheral demand for blood flow (e.g., via MRD) may influence CHT. Finally, my work on in vivo and in situ cardiac responses in tilapia provided little evidence for the hypothesis that hypoxic modulation of aerobic energy production pathways, including provision of aerobic fuels (specifically, fatty acids), contributes to CHT.

description: In a recent paper Bonitz, Pehlke and Schoof [1], hereafter referred to as BPS, have raised some points against the newly found Shukla-Eliasson attractive potential [2,3], hereafter refererred to as SEAP, around a stationary test charge in a quantum plasma [2,3]. Our objective here is to discuss the inappropriateness of BPS reasoning concerning the applicability of the linearized quantum hydrodynamic theory, as well as to point out the shortcomings in BSP's arguments and to suggest for rescuing the BSP's density functional theory and simulations which have failed to produce results that correctly match with that of Shukla and Eliasson [2,3].

description: Randomness is known to affect the dynamical behaviour of many systems to a large extent. In this paper we investigate how the nature of randomness affects the dynamics in a zero temperature quench of Ising model on two types of random networks. In both the networks, which are embedded in a one dimensional space, the first neighbour connections exist and the average degree is four per node. In the random model A, the second neighbour connections are rewired with a probability $p$ while in the random model B, additional connections between neighbours at Euclidean distance $l ~ (l >1)$ are introduced with a probability $P(l) \propto l^{-α}$. We find that for both models, the dynamics leads to freezing such that the system gets locked in a disordered state. The point at which the disorder of the nonequilibrium steady state is maximum is located. Behaviour of dynamical quantities like residual energy, order parameter and persistence are discussed and compared. Overall, the behaviour of physical quantities are similar although subtle differences are observed due to the difference in the nature of randomness.

description: Research has signaled the need for reformed biosimilar policy frameworks that adopt a behavioral approach, are informed by consensus-generating strategies and thus better align with the requirements of local healthcare communities. Through a series of co-creation workshops, the current study explores the feasibility of applying learnings from Collective Action Theory to formulate evidence-based multistakeholder-supported policy recommendations. Insights from the conducted workshops indicate that future policy frameworks would benefit from: 1) a working system of incentives and rewards aligned with stakeholder needs; 2) evaluating the cost-benefit balance for stakeholders prior to policy implementation; 3) involving multistakeholder panels in policy co-design; 4) adopting a long-term vision; 5) fostering coordination at the interface between levels of governance; 6) defining shared goals and efficient systems to monitor policy compliance; and 7) using policy outcome data to adapt current policy frameworks based on evolving needs. The incorporation of these elements to policies is expected to help prioritize long-term sustainable solutions, and balance short-term gains and long-term objectives in biosimilar markets. This study constitutes a first approach to developing multistakeholder-supported principles for sustainable biosimilar markets. This is a necessary step toward generating stakeholders’ consensus on biosimilar policies.
