description: By combining Herschel-SPIRE observations obtained as part of the Herschel Virgo Cluster Survey with 21 cm HI data from the literature, we investigate the role of the cluster environment on the dust content of Virgo spiral galaxies.We show for the first time that the extent of the dust disk is significantly reduced in HI-deficient galaxies, following remarkably well the observed 'truncation' of the HI disk. The ratio of the submillimetre-to- optical diameter correlates with the HI-deficiency, suggesting that the cluster environment is able to strip dust as well as gas. These results provide important insights not only into the evolution of cluster galaxies but also into the metal enrichment of the intra-cluster medium.

Motivation of Mandarin speakers learning Cantonese in a transnational context : multilingualism and investment
Creators: name: Li, Shuang
Publisher: name: University of British Columbia
Year: 2018

description: Globalization has intensified the cross-border mobility of people and languages, which contributes to the number of transnationals and the prevalence of multilingualism. Mandarin and Cantonese are two Chinese varieties and the competition between them has been transported from primarily Chinese-speaking regions to regions outside of Greater China, thereby creating an international issue among these transnational language users. In some overseas Chinese communities, Cantonese used to be the lingua franca but is currently declining and being replaced by Mandarin due to political, economic, cultural, and demographic factors. However, there is a new generation of Mandarin speakers interested in learning Cantonese in some English-dominant locations, such as Vancouver, Canada. In general, Mandarin is the sole official language in Mainland China and Cantonese is defined as a dialect, but this positioning is problematized in different contexts. This thesis will focus on one transnational context to explore the motivation of official-language (Mandarin) speakers to learn a value-declining regional language (Cantonese) in English-dominant Canada. The construct of motivation has been carefully scrutinized in the field of second language acquisition (SLA) in the past decades, but I find there is a huge gap between the research on motivation to learn English and languages other than English (LOTEs). This thesis examines if the English monopoly on motivational theories can be generalized to explain Cantonese learning behaviors among a transnational group of students in a transnational context. Through examining the Cantonese learning process of 61 Mandarin speakers in a Canadian university in both quantitative and qualitative ways, the study reveals that idealized multilingual identities play a significant role in motivating students to pick up Cantonese. Integrative motivation alone fails to capture the motivational features of the Cantonese learners in this study but instrumental motivation together with other intrinsic and extrinsic factors are still functional. Based on this study, instructors should recognize students’ transnational practices and global identities as resources to develop their multi-competence. Another prominent recommendation concerns the availability of formal language education in languages such as Cantonese, which supports the expansion of Cantonese language provision.
The opioid crisis as health crisis, not criminal crisis : implications for the criminal justice system
Creators: name: Hrymak, Haley
Publisher: name: University of British Columbia
Year: 2018

description: The criminal justice system’s response to the opioid crisis exacerbates risks faced by people using drugs and is harmful to public health. Through a literature review, caselaw analysis, and key-informant interviews in the Greater Vancouver area, this thesis analyzes elements of the criminal justice system’s response to the opioid crisis and provides recommendations to reduce harms experienced by people who use drugs and to promote community health and safety. An analysis of the British Columbia fentanyl trafficking sentencing decisions reveals that courts are emphasizing the need for enhanced deterrence as a response to the fentanyl crisis. In the street-level trafficking cases examined, 12 of the 14 people were motivated to traffic in order to support their own addiction. Interviews with 11 people including defence counsel, probation officers, and public interest lawyers and advocates, revealed challenges of working in the criminal justice system during the opioid crisis. Advocates described the main barrier as a fundamental misunderstanding of addiction within the criminal justice system. Advocates shared their insights into ways the criminal justice system can improve its approach. The key recommendation was for actors and policies within the criminal justice system to begin understanding the opioid crisis as a public health crisis and not a criminal crisis. A review of the literature reveals that lengthening custodial sentences for people who are trafficking fentanyl will not deter street-level trafficking. Instead, the court’s punitive approach will increase the number of individuals in custody, and disproportionately impact Indigenous people and those with substance abuse issues. Evidence-based harm reduction practices can be implemented in the justice system to reduce harm, from bail orders to prison conditions. There is a strong need for more rehabilitative options, community supports, and diversion opportunities to address the overrepresentation of people who use substances within custody.

description: Passive early-type galaxies (ETGs) provide an ideal laboratory for studying the interplay between dust formation around evolved stars and its subsequent destruction in a hot gas. Using Spitzer-IRS and Herschel data we compare the dust production rate in the envelopes of evolved AGB stars with a constraint on the total dust mass. Early-type galaxies which appear to be truly passively evolving are not detected by Herschel. We thus derive a distance independent upper limit to the dust grain survival time in the hostile environment of ETGs of < 46 +/- 25 Myr for amorphous silicate grains. This implies that ETGs which are detected at far-infrared wavelengths have acquired a cool dusty medium via interaction. Given likely time-scales for ram-pressure stripping, this also implies that only galaxies with dust in a cool (atomic) medium can release dust into the intra-cluster medium.

description: The neutron star low-mass X-ray binary EXO 0748-676 started a transition from outburst to quiescence in August 2008, after more than 24 years of continuous accretion. The return of the source to quiescence has been monitored extensively by several X-ray observatories. Here, we report on four XMM-Newton observations elapsing a period of more than 19 months and starting in November 2008. The X-ray spectra show a soft thermal component which we fit with a neutron star atmosphere model. Only in the first observation do we find a significant second component above ~ 3 keV accounting for ~ 7 % of the total flux, which could indicate residual accretion. The thermal bolometric flux and the temperature of the neutron star crust decrease steadily by 40 and 10 % respectively between the first and the fourth observation. At the time of the last observation, June 2010, we obtain a thermal bolometric luminosity of 5.6 x 10$^{33}$ (d/7.1 kpc)$^2$ erg s$^{-1}$ and a temperature of the neutron star crust of 109 eV. The cooling curve is consistent with a relatively hot, medium-mass neutron star, cooling by standard mechanisms. From the spectral fits to a neutron star atmosphere model we infer limits for the mass and the radius of the neutron star. We find that in order to achieve self-consistency for the NS mass between the different methods, the value of the distance is constrained to be

Evolution of Cool Close Binaries - Approach to Contact
Creators: name: Stepien, K.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: A set of 27 evolutionary models of cool close binaries was computed under the assumption that their evolution is influenced by the magnetized winds. Initial periods of 1.5, 2.0 and 2.5 d were considered. For each period three values of 1.3, 1.1 and 0.9 solar mass were taken as the initial masses of the more massive components. Here the results of the computations of the first evolutionary phase are presented, which starts from the initial conditions and ends when the more massive component reaches its critical Roche lobe. In all considered cases this phase lasts for several Gyr. For binaries with the higher total mass and/or longer initial periods this time is equal to, or longer than the main sequence life time of the more massive component. For the remaining binaries it amounts to a substantial fraction of this life time. From the statistical analysis of models, the predicted period distribution of detached binaries with periods shorter than 2 d was obtained and compared to the observed distribution from the ASAS data. An excellent agreement was obtained under the assumption that the period distribution in this range is determined solely by the mass and angular momentum loss due to the magnetized winds. This result indicates, in particular, that virtually all cool detached binaries with periods of a few tenths of a day, believed to be the immediate progenitors of W UMa-type stars, were formed from detached systems with periods around 2-3 d and that magnetic braking is the dominant formation mechanism of cool contact binaries. It operates on the time scale of several Gyr rendering them rather old, with age of 6-10 Gyr. The results of the present analysis will be used as input data to investigate the subsequent evolution of the binaries, through the mass exchange phase and contact or semi-detached configuration till the ultimate merging of the components.

Associations of bipolar traits with reward and threat sensitivity and conditioning
Creators: name: Terpstra, Alexander Roy
Publisher: name: University of British Columbia
Year: 2018

description: Bipolar Spectrum Disorders (BSDs) affect 1% of the population and cause significant interpersonal, occupational, and health challenges. Identifying cognitive, affective, and behavioural factors that influence BSD symptoms and related behaviours, consistent with a dimensional approach to psychopathology, may help improve our understanding and treatment of these disorders. Reward and threat sensitivity and learning, for example, are cognitive processes that may be dimensionally related to BSD risk, onset, and course. However, studies exploring reward and threat sensitivity and learning as a function of continuously measured bipolar traits, as opposed to categorical diagnoses or acute symptoms, have mostly employed self-report measures of sensitivity and overlooked classical conditioning. Thus, in this investigation, I explored how bipolar traits in two university student samples related to reward and threat sensitivity and conditioning measured using laboratory tasks. In Study 1, I found that higher self-reported lifetime hypomanic and depressive symptoms significantly predicted sensitivity to incentive reward and a stronger classically conditioned response to a threat-related cue, respectively. In Study 2, I addressed these questions in a larger sample of participants based on three higher-order bipolar traits as predictors of sensitivity and conditioning, variables extracted from measures of lower-order BSD-related traits using principal components analysis. Participants with higher scores for Factor 1, characterized by impulsiveness, low self-control, and low achievement, demonstrated significantly weaker classically conditioned responses to reward- and threat-related cues. Higher Factor 2 scores, indicating greater vulnerability to emotion dysregulation and negative affective responses to stress, significantly predicted greater sensitivity to threat. Finally, higher scores for Factor 3, reflecting a tendency to pursue and engage in stimulating experiences despite potential risks, significantly predicted greater sensitivity to incentive reward and lower susceptibility to forming classically conditioned responses to threat-related cues. These results indicate that bipolar traits may be meaningfully associated with patterns of reward and threat sensitivity and conditioning, associations which may have important implications for predicting and altering maladaptive levels of bipolar traits.

Searching for multi-nucleon processes in neutrino interactions by proton identification in the fine-grained detectors for T2K
Creators: name: Kim, Jiae
Publisher: name: University of British Columbia
Year: 2018

description: T2K is an accelerator-based neutrino experiment designed to observe neutrino oscillations with a baseline of 295 km across Japan from Tokai to Kamioka. Its main goal is to measure oscillation parameters (θ₂₃, Δm²₃₂ and θ₁₃) through νμ (overline{νμ}) disappearance and νe (overline{νe}) appearance channels. It has also begun to provide measurements of CP violation in the neutrino sector combining all four neutrino oscillation channels. However, the precision required for these experiments has resulted in the need to reduce challenging systematic uncertainties. Among all the uncertainties, the largest contribution comes from the neutrino interaction model, where nuclear effects are poorly understood. As neutrinos typically interact on nucleons that are almost always contained within nuclei, one immediately has to confront nuclear effects. Nuclear effects alter the kinematics of out-going particles from neutrino scatterings, and hence affect the neutrino oscillation measurements. Therefore it is crucial to understand the nuclear effects in these neutrino interactions. This dissertation describes the measurement of neutrino-nucleus interactions with no final state pion and at least one final state proton. Differential cross sections are measured as a function of kinematic variables, which utilize both muon and protons. An iterative unfolding technique is used to extract the cross sections. By providing unfolded and efficiency corrected results, this measurement can be more readily compared to theoretical models to allow a better understanding of nuclear effects in neutrino interactions, thereby providing valuable constraints on the systematic uncertainties associated with neutrino oscillation measurements for both T2K and other accelerator-based neutrino experiments.

description: We present a resolved dust analysis of three of the largest angular size spiral galaxies, NGC 4501 and NGC 4567/8, in the Herschel Virgo Cluster Survey (HeViCS) Science Demonstration field. Herschel has unprecedented spatial resolution at far-infrared wavelengths and with the PACS and SPIRE instruments samples both sides of the peak in the far infrared spectral energy distribution (SED).We present maps of dust temperature, dust mass, and gas-to-dust ratio, produced by fitting modified black bodies to the SED for each pixel. We find that the distribution of dust temperature in both systems is in the range ~19 - 22 K and peaks away from the centres of the galaxies. The distribution of dust mass in both systems is symmetrical and exhibits a single peak coincident with the galaxy centres. This Letter provides a first insight into the future analysis possible with a large sample of resolved galaxies to be observed by Herschel.

description: Recently it has become apparent that event-by-event fluctuations in the initial state of hydrodynamical modelling of ultrarelativistic heavy-ion collisions are crucial in order to understand the full centrality dependence of the elliptic flow coefficient v_2. In particular, in central collisions the density fluctuations play a major role in generating the spatial eccentricity in the initial state. This raises the question to what degree high P_T physics, in particular leading-parton energy loss, which takes place in the background of an evolving medium, is sensitive to the presence of the event-by-event density fluctuations in the background. In this work, we report results for the effects of fluctuations on the nuclear modification factor R_AA in both central and noncentral sqrt(s_NN) = 200 GeV Au+Au collisions at RHIC. Two different types of energy-loss models, a radiative and an elastic, are considered. In particular, we study the dependence of the results on the assumed spatial size of the density fluctuations, and discuss the angular modulation of R_AA with respect to the event plane.

description: Graphene has demonstrated great promise for future electronics technology as well as fundamental physics applications because of its linear energy-momentum dispersion relations which cross at the Dirac point. However, accessing the physics of the low density region at the Dirac point has been difficult because of the presence of disorder which leaves the graphene with local microscopic electron and hole puddles, resulting in a finite density of carriers even at the charge neutrality point. Efforts have been made to reduce the disorder by suspending graphene, leading to fabrication challenges and delicate devices which make local spectroscopic measurements difficult. Recently, it has been shown that placing graphene on hexagonal boron nitride (hBN) yields improved device performance. In this letter, we use scanning tunneling microscopy to show that graphene conforms to hBN, as evidenced by the presence of Moire patterns in the topographic images. However, contrary to recent predictions, this conformation does not lead to a sizable band gap due to the misalignment of the lattices. Moreover, local spectroscopy measurements demonstrate that the electron-hole charge fluctuations are reduced by two orders of magnitude as compared to those on silicon oxide. This leads to charge fluctuations which are as small as in suspended graphene, opening up Dirac point physics to more diverse experiments than are possible on freestanding devices.

The data taken on a single-crystalline sample along the orthorhombic crystal axes reveal a pronounced anisotropy, with the largest length changes along the $b$ axis. The large values of the step sizes $Δα$ at the magnetic and superconducting phase transitions provide solid evidence for bulk magnetism and superconductivity. Specific-heat measurements corroborate bulk superconductivity. Thermal-expansion measurements in magnetic fields $B \parallel a,b$ show $Δα$ at $T_C$ grows rapidly, which indicates the character of the ferromagnetic transition becomes first-order-like.

description: We study the evolution of the size - stellar mass relation for a large spectroscopic sample of galaxies in the GOODs North field up to $z \sim 3.5$. The sizes of the galaxies are measured from $\textit{K}_{s}$-band images (corresponding to rest-frame optical/NIR) from the Subaru 8m telescope. We reproduce earlier results based on photometric redshifts that the sizes of galaxies at a given mass evolve with redshift. Specifically, we compare sizes of UV-bright galaxies at a range of redshifts: Lyman break galaxies (LBGs) selected through the U-drop technique ($z \sim 2.5-3.5$), BM/BX galaxies at $z \sim 1.5-2.5$, and GALEX LBGs at low redshift ($z \sim 0.6-1.5$). The median sizes of these UV-bright galaxies evolve as $(1+z)^{-1.11\pm0.13}$ between $z \sim 0.5-3.5$. The UV-bright galaxies are significantly larger than quiescent galaxies at the same mass and redshift by $0.45\pm0.09$ dex. We also verify the correlation between color and stellar mass density of galaxies to high redshifts. The sizes of sub-mm galaxies in the same field are measured and compared with BM/BX galaxies. We find that median half-light radii of SMGs is $2.90 \pm 0.45$ kpc and there is little difference in their size distribution to the UV-bright star forming galaxies.

Drying and co-pelletization of microalgae with sawdust
Creators: name: Hosseinizand, Hasti
Publisher: name: University of British Columbia
Year: 2018

description: Post-harvest handling of microalgae following mechanical dewatering is challenging due to the high moisture content of biomass (about 65-75% wet basis). Therefore, thermal drying is applied to decrease the moisture content to the safe value for storage, handling, and transportation. After drying, handling of dried microalgae powder is still difficult because of its low bulk density and possibility of blocking the flow of material inside handling equipment. Pelletization improves microalgal material characteristics by making high-density and homogenous pellets. The first goal of this research is to study the thin-layer drying mechanism of microalgae Chlorella at the temperature range of 40-140° C. The second goal is to study densification mechanism of pure and mixed microalgae with pine sawdust. The specific species used in this experimental investigation is Chlorella vulgaris. In the studied temperature range, microalgae drying from an initial moisture content of 65% wet basis occurred in the falling-rate period with no constant-rate phase. The results revealed that diffusion is the controlling mechanism in microalgae drying and all the water is entrapped in algal cells. This confirms the industrial experience that further mechanical dewatering to remove water is not effective. It was also understood that although the drying rate at 100-140° C is the highest, 60 and 80° C are the optimum drying temperatures to preserve microalgae surface color and chemical composition. Pelletization of pure Chlorella occurred in two distinct regions of particles’ rearrangement and particles’ deformation. However, there was no clear separation between the two regions when pure sawdust was pelletized. Adding microalgae Chlorella to sawdust resulted in a decrease in densification energy and improvement in pellets’ properties, i.e. higher durability, density, and heating value, lower porosity, moisture adsorption, and pellets’ expansion. The results indicated that adding microalgae to sawdust eliminates the need for high pelletization temperature and force. The temperature of 75° C and maximum force of 2500 N, which are considered as moderate conditions, were adequate for making pellets containing microalgae with desirable characteristics because of the presence of natural binders in microalgae. Working at a low/moderate temperature and force improves the process economics by decreasing energy consumption.

description: FEUTURE Online Paper No. 24

This paper examines whether global security dynamics will act as either centripetal forces to the Turkey-EU relations on threat perceptions and security concerns, keeping the relationship aligned, or whether they will act as centrifugal forces pushing Tukey and the EU further apart on security. More precisely, the paper surveys the roles of (i) the US and NATO, (ii) Russia, and (iii) global security shifts as well as new (in-)security trends in this context. The paper argues that these three groups of global security dynamics will push Turkey-EU relations in a more conflictual direction, if cooperation—often more out of necessity than want—will continue to keep the relationship away from the brink, resulting in a form of conflictual cooperation. The paper concludes with a few initial recommendations.

description: We present the dust properties of a small sample of Virgo cluster dwarf galaxies drawn from the science demonstration phase data set of the Herschel Virgo Cluster Survey. These galaxies have low metallicities (7.8 < 12 + log(O/H) < 8.3) and star-formation rates < 10^{-1} M_{sun}/yr. We measure the spectral energy distribution (SED) from 100 to 500 um and derive dust temperatures and dust masses. The SEDs are fitted by a cool component of temperature T < 20 K, implying dust masses around 10^{5} M_{sun} and dust-to-gas ratios D within the range 10^{-3}-10^{-2}. The completion of the full survey will yield a larger set of galaxies, which will provide more stringent constraints on the dust content of star-forming dwarf galaxies.

description: We report on the correlation between the flux, color and polarization variations on time scales of days--months in blazars, and discuss their universal aspects. We performed monitoring of 42 blazars in the optical and near-infrared bands from 2008 to 2010 using TRISPEC attached to the "Kanata" 1.5-m telescope. We found that 28 blazars exhibited "bluer-when-brighter" trends in their whole or a part of time-series data sets. This corresponds to 88% of objects that were observed for >10 days. Thus, our observation unambiguously confirmed that the "bluer-when-brighter" trend is common in the emission from blazar jets. This trend was apparently generated by a variation component with a constant and relatively blue color and an underlying red component. Prominent short-term flares on time scales of days--weeks tended to exhibit a spectral hysteresis; their rising phases were bluer than their decay phases around the flare maxima. In contrast to the strong flux--color correlation, the correlation of the flux and polarization degree was relatively weak; only 10 objects showed significant positive correlations. Rotations of polarization were detected only in three objects: PKS 1510-089, 3C 454.3, and PKS 1749+096, and possibly in S5 0716+714. We also investigated the dependence of the degree of variability on the luminosity and the synchrotron peak frequency, ν_peak. As a result, we found that lower luminosity and higher ν_peak objects had smaller variations in their amplitudes both in the flux, color, and polarization degree. Our observation suggests the presence of several distinct emitting sources, which have different variation time-scales, colors, and polarizations. We propose that the energy injection by, for example, internal shocks in relativistic shells is a major factor for blazar variations on time scales of both days and months.

Irradiated bilayer graphene

description: We describe the gated bilayer graphene system when it is subjected to intense terahertz frequency electromagnetic radiation. We examine the electron band structure and density of states via exact diagonalization methods within Floquet theory. We find that dynamical states are induced which lead to modification of the band structure. We first examine the situation where there is no external magnetic field. In the unbiased case, dynamical gaps appear in the spectrum which manifest as dips in the density of states. For finite interlayer bias (where a static gap is present in the band structure of unirradiated bilayer graphene), dynamical states may be induced in the static gap. These states can show a high degree of valley polarization. When the system is placed in a strong magnetic field, the radiation induces coupling between the Landau levels which allows dynamical levels to exist. For strong fields, this means the Landau levels are smeared to form a near-continuum of states.

description: Abstract: The variability of climate has profoundly impacted a wide range of macroecological processes in the Late Quaternary. Our understanding of these has greatly benefited from palaeoclimate simulations, however, high-quality reconstructions of ecologically relevant climatic variables have thus far been limited to a few selected time periods. Here, we present a 0.5° resolution bias-corrected dataset of global monthly temperature, precipitation, cloud cover, relative humidity and wind speed, 17 bioclimatic variables, annual net primary productivity, leaf area index and biomes, covering the last 120,000 years at a temporal resolution of 1,000–2,000 years. We combined medium-resolution HadCM3 climate simulations of the last 120,000 years with high-resolution HadAM3H simulations of the last 21,000 years, and modern-era instrumental data. This allows for the temporal variability of small-scale features whilst ensuring consistency with observed climate. Our data make it possible to perform continuous-time analyses at a high spatial resolution for a wide range of climatic and ecological applications - such as habitat and species distribution modelling, dispersal and extinction processes, biogeography and bioanthropology.

description: The origin of the far-infrared emission from the nearby radio galaxy M87 remains a matter of debate. Some studies find evidence of a far-infrared excess due to thermal dust emission, whereas others propose that the far-infrared emission can be explained by synchrotron emission without the need for an additional dust emission component. We present Herschel PACS and SPIRE observations of M87, taken as part of the science demonstration phase observations of the Herschel Virgo Cluster Survey. We compare these data with a synchrotron model based on mid-infrared, far-infrared, submm and radio data from the literature to investigate the origin of the far-infrared emission. Both the integrated SED and the Herschel surface brightness maps are adequately explained by synchrotron emission. At odds with previous claims, we find no evidence of a diffuse dust component in M87, which is not unexpected in the harsh X-ray environment of this radio galaxy sitting at the core of the Virgo Cluster.

description: In this research, the total phenolics, antioxidant activity, and antibacterial susceptibility of Salvia microphylla leaf extracts were studied using solvents of varying polarity (n-hexane, dichloromethane, ethyl acetate, and 80% methanol). Total phenolic content (TPC) and total flavonoid content (TFC) were estimated using the Folin-Ciocalteu and aluminium chloride colorimetric methods, respectively. Phytochemical analysis was conducted using the LC-ESI-MS/MS method. By using the FRAP and DPPH methods, the antioxidant activities were measured spectrophotometrically. The antimicrobial assay was done through the agar-well diffusion method against the Gram-negative and Gram-positive bacteria. All extracts showed potent antimicrobial activity, with the hexane extract displaying strong inhibitory effects. These findings indicate that S. microphylla leaf extracts contain promising bioactive compounds possessing antioxidant and antibacterial properties, suggesting further research to isolate and characterise these bioactive compounds and assess their in vivo effects.
