description: The first results from heavy ion collisions at the Large Hadron Collider for charged particle spectra and elliptic flow are compared to an event-by-event hybrid approach with an ideal hydrodynamic expansion. This approach has been shown to successfully describe bulk observables at RHIC. Without changing any parameters of the calculation the same approach is applied to Pb+Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV. This is an important test if the established understanding of the dynamics of relativistic heavy ion collisions is also applicable at even higher energies. Specifically, we employ the hybrid approach with two different equations of state and the pure hadronic transport approach to indicate sensitivities to finite viscosity. The centrality dependence of the charged hadron multiplicity, $p_T$ spectra and differential elliptic flow are shown to be in reasonable agreement with the ALICE data. Furthermore, we make predictions for the transverse mass spectra of identified particles and triangular flow. The eccentricities and their fluctuations are found to be surprisingly similar to the ones at lower energies and therefore also the triangular flow results are very similar. Any deviations from these predictions will indicate the need for new physics mechanisms responsible for the dynamics of heavy ion collisions.

Thermal modification of Western hemlock (Tsuga heterophylla)
Creators: name: Nourian, Sepideh
Publisher: name: University of British Columbia
Year: 2019

description: Thermal modification is a controlled degradation process of wood cell wall material at high temperatures that results in improving some of its properties. This process, albeit quite developed in Europe, is still in its infancy in Canada. So, use of such method might add value to local wood species and thus, allow the development of new products and markets. Western Hemlock (Tsuga heterophylla) is a locally abundant species used mostly in construction, so the development of other uses could bring extra revenues to the industry. This research focuses on exploring thermal treatment levels and their effect on some material properties in order to achieve the optimum combination for hemlock. In this regard, kiln-dried western hemlock boards with two cuts (flatsawn and quartersawn) were subjected to the Thermowood® process at three different maximum treatment temperatures (170, 212, and 230°C) for 2hrs. Samples were cut from both the treated and untreated boards for property evaluation tests including basic density, equilibrium moisture content, water absorption, anti-swelling efficiency, color change, Janka hardness, and dynamic modulus of elasticity. Data analysis revealed that there was no significant difference between the two cuts and temperature was the only factor that affected the wood properties. Basic density, equilibrium moisture content, and water absorption were lower at higher treatment temperatures, while dimensional stability considerably increased. The impact of higher treatment temperatures on hardness and stiffness of samples was hardly noticeable, but it visually influenced the color of samples and made them darker. Within the scope and limitations of this study, the optimum treatment temperature, namely, the one that enables improved dimensional stability and provided a darker color without significantly affecting the wood strength suggested establishing at 212°C. Further research is required to fully determine the performance of thermally modified wood for interior and exterior applications.

description: This paper describes the results of an HST WFPC2 search for star clusters in active star-formation regions of M31. Nine of the clusters were previously cataloged and 77 are new. Our 23 fields cover key areas of the galaxy's recent star formation activity. We provide a catalog of positions and integrated magnitudes in four colors, taken with the 336W, 439W, 555W and 814W filters with the Hubble Space Telescope. A future paper will discuss the results of stellar photometry in some of the clusters in six colors, including two additional uv colors (Bianchi et al. 2010). The integrated magnitudes and colors of the clusters show a range of characteristics, but the mean color is bluer than for previous surveys, reflecting the concentration of our sample on active star forming regions. Absolute magnitudes range from M555 = -10.3 to - 3.5. The observed luminosity function shows a nearly Gaussian distribution with a peak value at M555 = -5.4 and a shoulder of unusually-bright clusters. We look in detail at two of these unusually bright examples, cluster 45 (C410) and cluster 10 (BH05). C410 lies at the core of a bright HII region. Its absolute magnitude is M555 = -10.3. BH05 is a similar object, with an absolute magnitude of M555 = -8.9. These two clusters are among the most luminous young clusters in M31.

description: This document is produced as part of ongoing efforts within WP3 of the EOSC-Nordic project. The task specifically aims at creating a set of tools to support the adoption of EOSC by service providers in the Nordics and Baltics and to allow accessing services as well as provisioning them in a programmatic way. This deliverable is written during a transitional period of EOSC, before the EOSC Future is launched and EOSC Association becomes functional. Both are major factors to further evolve the EOSC ecosystem both in governance and technical level. Due to the EOSC Rules of Participation still being developed, this report builds upon best practice and knowledge gained within the EOSC-Nordic project collaboration. The reader should therefore be aware that some of the approaches taken might become obsolete or incorrect, once the future EOSC Rules of Participation are adapted. The team behind this deliverable will allow for continuous adaptations of operational actions in accordance with the guidelines set out by the EOSC Association. The EOSC-Nordic team plans to summarise the end result in the next iteration of the deliverable during the year 2022.

 It should be highlighted that the current state of affairs with respect to EOSC Sustainability is a significant blocker for the adoption of the programmatic access method, as it typically incurs process change or investments by the service providers. A lack of clarity on mechanisms of EOSC resource usage compensation demotivates service providers to do so. We see clarity on EOSC Sustainability as critical for the success of both EOSC as well as regional EOSC integrators (alias pre-boarding platforms) for programmatic access to EOSC services.

description: The extragalactic background light (EBL) is the relic emission of all processes of structure formation in the Universe. About half of this background, called the Cosmic Infrared Background (CIB) is emitted in the 8-1000 microns range, and peaks around 150 microns. It is due to the dust reemission from star formation processes and AGN emission. The CIB spectral energy distribution (SED) constraints the models of star formation in the Universe. It is also useful to compute the opacity of the Universe to the TeV photons. We present the different types of measurements of the CIB and discuss their strengths and weaknesses. 1. The absolute SED was measured by COBE, and by other experiments. These measurements are limited by the accuracy of the component separation, i.e. the foreground subtraction. 2. Robust lower limits are determined from the extragalactic number counts of infrared galaxies. These lower limits are very stringent up to 100 microns. At larger wavelengths, the rather low angular resolution of the instruments limits strongly the depth of the number counts. The "stacking" method determines the flux emitted at a given wavelength by a population detected at another wavelength, and provides stringent lower limits in the sub-mm range. It is complementary with other methods based on the statistical analysis of the map properties like the P(D) analysis. 3. Finally, upper limits can be derived from the high energy spectra of extragalactic sources. These upper limits give currently good constraints in the near- and mid-IR. Progress have been amazing since the CIB discovery about 15 years ago: the SED is much better known, and most of it can be accounted for by galaxies (directly or indirectly). Prospects are also exciting, with fluctuation analysis with Planck&Herschel, and forthcoming missions.

description: The RGB-Depth (RGB-D) Video Object Segmentation (VOS) aims to integrate the fine-grained texture information of RGB with the spatial geometric clues of depth modality, boosting the performance of segmentation. However, off-the-shelf RGB-D segmentation methods fail to fully explore cross-modal information and suffer from object drift during long-term prediction. In this paper, we propose a novel RGB-D VOS method via multi-store feature memory for robust segmentation. Specifically, we design the hierarchical modality selection and fusion, which adaptively combines features from both modalities. Additionally, we develop a segmentation refinement module that effectively utilizes the Segmentation Anything Model (SAM) to refine the segmentation mask, ensuring more reliable results as memory to guide subsequent segmentation tasks. By leveraging spatio-temporal embedding and modality embedding, mixed prompts and fused images are fed into SAM to unleash its potential in RGB-D VOS. Experimental results show that the proposed method achieves state-of-the-art performance on the latest RGB-D VOS benchmark.

description: Membrane-assisted CO2 liquefaction is a hybrid, two-stage separation process for capturing CO2

from flue gas. The first separation stage consists of a CO2-selective polymeric membrane unit

separating the bulk of CO2 from the flue gas. The resulting permeate on the vacuum side of the

membrane is a crude CO2 product, still containing a considerable fraction of diluents such as

nitrogen, oxygen and water. Before entering the second CO2 separation stage, the permeate is

compressed and dehydrated before it is cooled to around -54°C by recuperative and auxiliary

refrigeration. In two separation stages the CO2 is liquefied and purified for transport and storage.

The gaseous separation product is recycled to the inlet of the membrane unit.

Six different cases have been evaluated. Two different cement plant flue gas compositions have

been considered (with 18 mol% and 22 mol% CO2 concentration respectively), and two main

CO2 capture ratios have been targeted (90 % and 60 %).

A multicomponent membrane model is used to simulate the membrane separation process, and

this has been integrated into the interface of the commercial process simulator Aspen HYSYS.

Global process models for the hybrid membrane-assisted CO2 liquefaction process have been

used in the case studies. The assumed membrane material has a selectivity of 50 for CO2 over

nitrogen, and the total membrane surface areas used in simulations are 228 000 m3 and

152 000 m3 for 90 % and 60 % capture ratio, respectively.

The net electric power requirement for the hybrid CO2 capture process varies between

1066 kJ/kgCO2 for 60 % CO2 capture ratio from the flue gas with 22 mol% CO2 concentration,

and 1458 kJ/kgCO2 for 90 % CO2 capture ratio from the flue gas with 18 mol% CO2 concentration.

The power requirement is in all cases caused mainly by flue gas compression, vacuum pumping

and compression of crude CO2 permeate, and auxiliary refrigeration.

Compared to other end-of-pipe capture technologies, the performance of membrane-based

processes is highly sensitive to CO2 concentration in the flue gas stream. Therefore, in addition

to optimising membrane materials and configurations, it is equally important to reduce the air

ingress to increase CO2 concentrations in the flue gas. This will contribute to improving the

performance of membrane-assisted CO2 liquefaction.

description: We present and analyze the radial luminosity profiles of a sample of 1066 stellar clusters in the Large Magellanic Cloud. By design, this study closely follows the compilation by Hill & Zaritsky of the structural parameters of stellar clusters in the Small Magellanic Cloud. Both King and Elson-Fall-Freeman (EFF) model profiles are fit to V-band surface brightness profiles measured from the Magellanic Cloud Photometric Survey images. We tabulate the concentration, central surface brightness, tidal radii, 90% enclosed luminosity radii (r_{90}), and local background luminosity density. Over two thirds of the clusters in the sample are adequately fit by one or both of these models. One notable and systematic exception, as in the SMC, are those clusters that lack a central brightness concentration, the "ring" clusters. While the bulk properties of the clusters are similar between the LMC and SMC populations, we find that the LMC lacks clusters that are as large, either in terms of core radii or r_{90}, as the largest in the SMC, perhaps a signature of larger tidal stresses in the LMC.

Linking landscape indicators to groundwater nitrate concentrations in a transboundary aquifer
Creators: name: Gallagher, Tanya Louise
Publisher: name: University of British Columbia
Year: 2018

description: Groundwater aquifers provide nearly half the freshwater used in drinking and cooking. However, in the last century, massive transformations of landscapes have produced enduring impacts on natural resources such as groundwater. Excess nitrate contamination of groundwater is a growing health concern, particularly in agricultural regions. Despite its importance, very few studies have quantitatively linked land use land cover (LULC) and groundwater nitrate concentrations. Furthermore, understanding the impacts of LULC on transnational water resources is especially challenging as multi-jurisdictional data disparities and inconsistencies can complicate monitoring efforts. Here, I developed a suite of innovative long-term monitoring approaches and evaluated their utility in a well-studied transnational aquifer where elevated groundwater nitrate concentrations are of concern. My overall objective was to develop approaches for examining LULC impacts to groundwater via two primary components. First, I used remote sensing to examine two decades of LULC change surrounding 11 groundwater dependent cities. Second, I created more localized landscape indicators and evaluated their correspondence to long-term trends in groundwater nitrate concentrations. I examined two nested spatial extents spanning the US-Canada border including: small cities throughout the Greater Abbotsford-Sumas Aquifer region as well as the confined extent of the Abbotsford-Sumas Aquifer (ASA) proper. I integrated a unique combination of historical photography, transnational satellite imagery, and groundwater monitoring wells spanning four decades. Throughout the larger region, I found that landscape evenness increased over time driven by greater forest losses in Canada and greater losses of agricultural land in the USA. Within the localized ASA, I determined that groundwater nitrate concentrations could be explained using landscape features measured within the vicinity of wells. Landscape indicators such as the proportional area of berries, raspberry fields undergoing renovations, as well as forage/pasture were particularly useful. I further determined that long-term trends in nitrate were best explained by historical landscape indicators from two decades prior (as opposed to contemporaneous indicators). Very few studies have examined LULC emphasizing transboundary aquifers and even fewer have quantitatively linked groundwater nitrate concentrations to land use practices. Thus, this work demonstrates a valuable, consistent monitoring approach that is transportable to other regions facing similar challenges.

description: Iodine added to iodide-based ionic liquids leads to extraordinarily efficient charge transport, vastly exceeding that expected for such viscous systems. Using terahertz time-domain spectroscopy, in conjunction with dc conductivity, diffusivity and viscosity measurements we unravel the conductivity pathways in 1-methyl-3-propylimidazolium iodide melts. This study presents evidence of the Grotthuss mechanism as a significant contributor to the conductivity, and provides new insights into ion pairing processes as well as the formation of polyiodides. The terahertz and transport results are reunited in a model providing a quantitative description of the conduction by physical diffusion and the Grotthuss bond-exchange process. These novel results are important for the fundamental understanding of conduction in molten salts and for applications where ionic liquids are used as charge-transporting media such as in batteries and dye-sensitized solar cells.

The mechanical mode is modeled to have fundamental resonance omega_m/2pi of 460 MHz and a quality factor Qm estimated at 12,000. For this slot-type optomechanical cavity, the dispersive coupling gom is numerically computed at up to 940 GHz/nm (Lom of 202 nm) for the fundamental optomechanical mode. Dynamical parametric oscillations for both cooling and amplification, in the resolved and unresolved sideband limit, are examined numerically, along with the displacement spectral density and cooling rates for the various operating parameters.

description: Using Riemann-Stieltjes methods for integrators of bounded $p$-variation we define a pathwise integral driven by a fractional Lévy process (FLP). To explicitly solve general fractional stochastic differential equations (SDEs) we introduce an Ornstein-Uhlenbeck model by a stochastic integral representation, where the driving stochastic process is an FLP. To achieve the convergence of improper integrals, the long-time behavior of FLPs is derived. This is sufficient to define the fractional Lévy-Ornstein-Uhlenbeck process (FLOUP) pathwise as an improper Riemann-Stieltjes integral. We show further that the FLOUP is the unique stationary solution of the corresponding Langevin equation. Furthermore, we calculate the autocovariance function and prove that its increments exhibit long-range dependence. Exploiting the Langevin equation, we consider SDEs driven by FLPs of bounded $p$-variation for $p<2$ and construct solutions using the corresponding FLOUP. Finally, we consider examples of such SDEs, including various state space transforms of the FLOUP and also fractional Lévy-driven Cox-Ingersoll-Ross (CIR) models.

description: The concept of a protein diffusing in its free energy folding landscape has been fruitful for both theory and experiment. Yet the choice of the reaction coordinate (RC) introduces an undesirable degree of arbitrariness into the problem. We analyze extensive simulation data of an alpha-helix in explicit water solvent as it stochastically folds and unfolds. The free energy profiles for different RCs exhibit significant variation, some having an activation barrier, others not. We show that this variation has little effect on the predicted folding kinetics if the diffusivity profiles are properly taken into account. This kinetic quasi-universality is rationalized by an RC rescaling, which, due to the reparameterization invariance of the Fokker-Planck equation, allows the combination of free energy and diffusivity effects into a single function, the rescaled free energy profile. This rescaled free energy indeed shows less variation among different RCs than the bare free energy and diffusivity profiles separately do, if we properly distinguish between RCs that contain knowledge of the native state and those that are purely geometric in nature. Our method for extracting diffusivity profiles is easily applied to experimental single molecule time series data and might help to reconcile conflicts that arise when comparing results from different experimental probes for the same protein.

description: Light-cone gauge superstring theory in noncritical dimensions corresponds to a worldsheet theory with nonstandard longitudinal part in the conformal gauge. The longitudinal part of the worldsheet theory is a superconformal field theory called X^{\pm} CFT. We show that the X^{\pm} CFT combined with the super-reparametrization ghost system can be described by free variables. It is possible to express the correlation functions in terms of these free variables. Bosonizing the free variables, we construct the spin fields and BRST invariant vertex operators for the Ramond sector in the conformal gauge formulation. By using these vertex operators, we can rewrite the tree amplitudes of the noncritical light-cone gauge string field theory, with external lines in the (R,R) sector as well as those in the (NS,NS) sector, in a BRST invariant way.

description: Systematic observations of the magnetically generated fountain pressure in the superfluid $^3$He A$_1$ have been carried out in a newly built apparatus designed to reduce the effect of thermal gradients. In the same apparatus, mechanical pumping and filtering of polarized nuclear spins were realized by the pneumatic pumping action of an electrostatically actuated membrane. In both experiments, the measured induced pressure was observed to decay at all temperatures where the A$_1$ phase appeared in magnetic fields up to 13 T and liquid pressures between 1 and 29 bar. The inferred spin relaxation rate tended to increase as the low temperature phase boundary with the A$_2$ phase (T$_{C2}$) was approached. The increase in spin relaxation rate near T$_{C2}$ can be explained by the presence of a minority spin condensate in the A$_1$ phase as predicted by Monien and Tewordt and by the application of the Leggett-Takagi theory of spin relaxation in superfluid $^3$He.

description: I wake up, log on to Microsoft teams for a revision class or a lecture. I then start going over the notes I was making back in 2017, 2018 and the beginning of this year. On the days of the actual exam, I have to upload my essays to Weblearn; typing out my finals is a strange experience and has changed the nature of the exams. I am relieved they are over, but I'm now aware of how much time I have to fill, reflecting upon how solitary the experience has been, and how I would love to be celebrating the end of my degree with my friends and tutors back in Oxford. I'm lucky that I've been able to keep my mind occupied for the past two months in a safe environment but I am anxious about what world I will be entering.

description: VFTS 682 is located in an active star-forming region, at a projected distance of 29 pc from the young massive cluster R136 in the Tarantula Nebula of the Large Magellanic Cloud. It was previously reported as a candidate young stellar object, and more recently spectroscopically revealed as a hydrogen-rich Wolf-Rayet (WN5h) star. Our aim is to obtain the stellar properties, such as its intrinsic luminosity, and to investigate the origin of VFTS 682. To this purpose, we model optical spectra from the VLT-FLAMES Tarantula Survey with the non-LTE stellar atmosphere code CMFGEN, as well as the spectral energy distribution from complementary optical and infrared photometry. We find the extinction properties to be highly peculiar (RV ~4.7), and obtain a surprisingly high luminosity log(L/Lsun) = 6.5 \pm 0.2, corresponding to a present-day mass of ~150Msun. The high effective temperature of 52.2 \pm 2.5kK might be explained by chemically homogeneous evolution - suggested to be the key process in the path towards long gamma-ray bursts. Lightcurves of the object show variability at the 10% level on a timescale of years. Such changes are unprecedented for classical Wolf-Rayet stars, and are more reminiscent of Luminous Blue Variables. Finally, we discuss two possibilities for the origin of VFTS 682: (i) the star either formed in situ, which would have profound implications for the formation mechanism of massive stars, or (ii) VFTS 682 is a slow runaway star that originated from the dense cluster R136, which would make it the most massive runaway known to date.

description: Whenever a distinct state is immersed in a sea of complicated and dense states, the strength of the distinct state, which we refer to as a doorway, is distributed in their neighboring states. We analyze this mechanism for 2-D billiards with different geometries. One of them is symmetric and integrable, another is symmetric but chaotic, and the third has a capricious form. The fact that the doorway-state mechanism is valid for such highly diverse cases, proves that it is robust.

Visual rhetoric in environmental documentaries

Publisher: name: University of British Columbia
Year: 2018

description: Environmental issues are a growing, global concern. UNESCO (1997) notes the significant role media has in appealing to audiences to act in sustainable ways. Cox (2013) specifically remarks upon the powerful role images play in how viewers can perceive the environment. As we contemplate how best to engage people in reflecting on what it means to live in a sustainable fashion, it is important that we consider the merits of particular rhetorical modes in environmental communication and how those approaches may engender concern or hopelessness, engagement or disengagement. One form of environmental communication that relies heavily on images, and that is growing in popularity, is documentary film. My study examines visual rhetorical modes in environmental documentaries and the types of impact they have on viewers. This study first identifies some dominant visual rhetorical modes through an extensive literature review and discussion of a variety of environmental documentary films. The resulting taxonomy of dominant visual rhetorical modes include: apocalyptic, jeremiad, hopeful, environmental nostalgia, sublime, and environmental melodrama. To explore how viewers react to visual rhetoric, eleven research participants were asked to view a sixty-minute compilation of video clips from various environmental documentaries that employed, to varying degrees, each of the dominant visual rhetorical modes. Using video annotation software, participants were asked to comment at points they felt to be particular striking or evocative. Follow-up interviews were conducted for clarification of participants’ annotations. The data collected and analyzed from participants’ annotations and transcribed interviews revealed that viewers were disengaged with messages of ecological doom. The most powerful rhetorical effect was observed when participants drew personal connections to content of particular video clips, which raised their awareness about certain environmental issues.

description: I review recent results obtained within chiral effective models, on the phase structure of hot quark matter in a strong magnetic background. After a brief introduction, I focus on the results obtained within two chiral models improved with the Polyakov loop. The models differ for the content of interactions, but both of them are tuned to reproduce Lattice QCD thermodynamics at zero and imaginary chemical potential. One of them takes into account an explicit Polyakov loop dependence of the coupling; the other one neglects this contribution, but takes into account multi-quark interactions. A comparison between the phase diagrams of the two models is presented.

The effect of remyelination blockade on axon survival and damage in experimental autoimmune encephalomyelitis
Creators: name: Brown, Douglas Robert
Publisher: name: University of British Columbia

description: Multiple sclerosis is the most common cause of neurologic disability in the developed world. A heterogeneous disease of unknown cause that most often presents in mid life, it is characterized by years of relapsing and remitting symptoms that eventually become progressive. The pathology of Multiple Sclerosis is characterized by resolving and non-resolving neurological deficits caused by axonal dysfunction and degeneration, which are mediated by both inflammation and demyelination. Remyelination is an intrinsic myelin repair mechanism that replaces lost myelin in response to demyelination and mitigates its pathological effects. Experimentally, remyelination has been shown to promote axon survival in inflammatory demyelination contexts, however, it is unknown if blocking remyelination will result in increased axon loss and damage. Determining the importance of remyelination for axon preservation is necessary to determine the efficacy of remyelination therapies. Assessing the effect of blocked remyelination is an important part of this picture. To determine this we used the rodent model of MS, Experimental Autoimmune Encephalomyelitis (EAE), to initiate demyelination, and blocked remyelination by inducibly deleting the gene Myelin Gene Regulatory Factor (Myrf) using the Cre-lox gene editing system. We then assessed axon survival and damage, myelination state, EAE disease severity and progression, microglial activation, and dorsal column size in the lumbar spinal cord of affected mice. We found that blocked remyelination did not affect axon survival or damage, but delayed EAE disease onset, reduced myelin in the ventral white matter and increase activation of microglia in affected areas. Strictly interpreted, our results suggest that remyelination may not be as important for axon survival as hypothesized. However, non-statistically significant trends in the results (Axon Loss p = 0.11 and Axon damage p = 0.15 in ventral/dorsal white matter combined) suggest that the lack of effect seen here may have been due to limitations and unforeseen problems encountered during these experiments. Unfortunately, these casts some doubt on our findings, but may highlight some previously unknown difficulties and effects such as delayed EAE induction and increased disease severity that may have been unintended consequences of the Myrf knock out, indicating that more investigation is warranted.
