Constructing, presenting, and expressing self on social network sites : an exploratory study in Chinese university students’ social media engagement
Creators: name: Guo, Yu
Publisher: name: University of British Columbia
Year: 2015

description: During past few years, social media, particularly social network sites (SNS) have emerged and attracted an increasing number of young people. SNS is a significant venue for youth to construct their identities through the interaction with their peers. Most current literature, available in English, focuses on the experiences of youth with SNS who live in Western societies. This exploratory study explores how undergraduates at universities in China construct, present and express their identity on SNS in relation to others. Five semi-structured interviews were conducted with college students to capture their lived experience with SNS. I drew on concepts of identity, subjectivity and dramaturgy and literature that examine tensions between concepts of collectivism and individualism in China. This study concludes that: Firstly, SNS provides a space for young people to explore and perform themselves towards what they see as their ideal self. However it does not mean young people can construct a brand new identity without the intervention of their offline identity. How they construct themselves and how they are constructed occurs in relation to their offline friendship circle as to the discursive world they live within. Participants spoke about the tensions in trying to balance collectivistic culture and individualistic culture, which influenced participants' sense of self and the way they presented themselves on SNS. Young people are deeply involved in their online presence and reality, and so both discursive worlds influence who they think they are in relation to others. Secondly, SNS is a “front stage” for young people to deliberately present themselves and manage the impression they gave to others. Both written texts and visualized pictures afford young people to “give” or “give off” their performance to their online audience (Goffman, 1959, p. 3). However on SNS the boundary between “front stage” and “back stage” is blurred and it is difficult for participants to keep track of different online and offline connections and, based on this, what to post. The study points to the importance of understanding SNS use within the particularities of cultural contexts.

description: In this paper, we investigate two new candidate transmission schemes, Non-Orthogonal Frequency Reuse (NOFR) and Beam-Hoping (BH). They operate in different domains (frequency and time/space, respectively), and we want to know which domain shows overall best performance. We propose a novel formulation of the Signal-to-Interference plus Noise Ratio (SINR) which allows us to prove the frequency/time duality of these schemes. Further, we propose two novel capacity optimization approaches assuming per-beam SINR constraints in order to use the satellite resources (e.g. power and bandwidth) more efficiently. Moreover, we develop a general methodology to include technological constraints due to realistic implementations, and obtain the main factors that prevent the two technologies dual of each other in practice, and formulate the technological gap between them. The Shannon capacity (upper bound) and current state-of-the-art coding and modulations are analyzed in order to quantify the gap and to evaluate the performance of the two candidate schemes. Simulation results show significant improvements in terms of power gain, spectral efficiency and traffic matching ratio when comparing with conventional systems, which are designed based on uniform bandwidth and power allocation. The results also show that BH system turns out to show a less complex design and performs better than NOFR system specially for non-real time services.

Multisyllabic word production of school-aged children with and without protracted phonological development
Creators: name: Mason, Glenda
Publisher: name: University of British Columbia
Year: 2015

description: Few studies exist concerning multisyllabic word development, yet researchers suggest that evaluation of long words is essential for phonological assessment of school-aged children (e.g. Holm, Farrier, & Dodd, 2008; James, 2006). Furthermore, multisyllabic word (MSW) production may be related to literacy development (Carroll & Snowling, 2004). The goal of this thesis therefore was to further study the phonological acquisition of MSWs. The dissertation begins with a meta-analysis (Chapter 2) that examines factors related to word level literacy skills in children with and without protracted phonological development (PPD). Fifty-two eligible studies were evaluated that had measured at least one word level literacy construct. Sixty-four independent samples were generated for evaluation of: Phonological awareness, Decoding, Fluency, Nonword decoding and Spelling. A mean mixed weighted d was compared on the Q-statistic using a random effects model. MSW evaluation was a relevant moderator of literacy for children with PPD as expected and motivated the remainder of the thesis. A pilot study (Chapter 3) evaluated a new MSW metric based on nonlinear phonological and language processing frameworks. Six MSWs were analyzed for ten English-speaking typically developing (TD) 5-year-olds, and eight French-speaking 3- to 4-year-olds with PPD. Mismatches were tallied and ranked, and compared with tallies from Phonological Mean Length of Utterance (Ingram, 2002) and Percent Consonants Correct (Shriberg, Austin, Lewis, McSweeny, & Wilson, 1997). The number of different ranks was significant and systematically higher with the new metric. Chapter 4 examines production of 20 MSWs in three sub-studies: (a) longitudinal: 44 TD children at ages 5 and 8 to 10 years; (b) cross-sectional by age: twelve age-matched 8- to 10-year-olds with and without PPD; and (c) cross-sectional by group: 62 TD 5-year-olds and the 12 8- to 10-year-olds with PPD. Lexical and phonological tallies decreased significantly between ages 5 and 8 years for the TD children. The 8- to 10-year-olds with PPD showed overall scores equivalent to those of the TD 5-year-olds although some different mismatch (error) patterns. In summary, the thesis further examines the link between MSWs and literacy and provides both a new whole-word metric for MSWs and phonological data for school-aged children.

On multidimensional cosmological solutions with scalar fields and 2-forms corresponding to rank-3 Lie algebras: acceleration and small variation of G

description: By means of a simple model we investigate the possibility of an accelerated expansion of a 3-dimensional subspace in the presence of the variation of the effective 4-dimensional constant obeying the experimental constraint. Multidimensional cosmological solutions with m 2-form fields and l scalar fields are presented. Solutions corresponding to rank-3 Lie algebras are singled out and discussed. Each of solutions contain two factor spaces: one-dimensional space M_1 and Ricci-flat space M_2. A 3-dimensional subspace of M_2 is interpreted as "our" space. We show that there exists a time interval where accelerated expansion of our 3D space is compatible with a small enough variation of the effective gravitational constant G(τ). This interval contains τ_0 which is the point of minimum of G(τ) (here τis the synchronous time variable). Special solutions with three phantom scalar fields are analyzed. It is shown that in the vicinity of the point τ_0 the time variation of G(τ) decreases in the sequence of Lie algebras A_3, C_3 and B_3 when the solutions with asymptotically power-law behavior of scale-factors for τ\to \infty are considered. Exact solutions with asymptotically exponential accelerated expansion of 3D space are also considered.

description: Inversion of NASA Operation IceBridge airborne gravity over the Abbot Ice Shelf in West Antarctica for subice bathymetry defines an extensional terrain made up of east-west trending rift basins formed during the early stages of Antarctica/Zealandia rifting. Extension is minor, as rifting jumped north of Thurston Island early in the rifting process. The Amundsen Sea Embayment continental shelf west of the rifted terrain is underlain by a deeper, more extensive sedimentary basin also formed during rifting between Antarctica and Zealandia. A well-defined boundary zone separates the mildly extended Abbot extensional terrain from the deeper Amundsen Embayment shelf basin. The shelf basin has an extension factor, b, of 1.5–1.7 with 80–100 km of extension occurring across an area now 250 km wide. Following this extension, rifting centered north of the present shelf edge and proceeded to continental rupture. Since then, the Amundsen Embayment continental shelf appears to have been tectonically quiescent and shaped by subsidence, sedimentation, and the advance and retreat of the West Antarctic Ice Sheet. The Bellingshausen Plate was located seaward of the Amundsen Sea margin prior to incorporation into the Antarctic Plate at about 62 Ma. During the latter part of its independent existence, Bellingshausen plate motion had a clockwise rotational component relative to Antarctica producing convergence across the north-south trending Bellingshausen Gravity Anomaly structure at 94°W and compressive deformation on the continental slope between 94°W and 102°W. Farther west, the relative motion was extensional along an east-west trending zone occupied by the Marie Byrd Seamounts.
Health implications of food away from home consumption : a marketing and policy analysis
Creators: name: Ghotbi, Sina
Publisher: name: University of British Columbia
Year: 2015

description: This thesis provides two independent empirical quantitative studies on consumer decision-making in the context of food-away-from-home consumption, and examines important public policy and marketing issues. We first study whether meals with diet carbonated soft drinks (CSD) have more calories than meals with regular CSD by investigating an individual-level meal consumption panel dataset between 2000 and 2007 at a major fast-food chain in Canada. This study is motivated by the debate on the effectiveness of diet CSD on weight loss and is the first to provide field-based evidence, supported by within subject variation, on the harm and benefit of diet drinks in terms of caloric consumption within a meal. We find no increase in total calories consumed during a meal, and most diet CSD drinkers also exhibit a reduction in total calories. Looking more narrowly at the food calories in a meal we find that young males are the only group who have more food calories when they choose a diet drink, yet the extra food calories do not exceed the calories saved by consuming diet rather than regular CSD. In the second study, using an individual-level panel dataset on food consumed in all restaurants in Canada, we examine the effect of media coverage of multiple instances of Bovine Spongiform Encephalopathy (BSE – mad cow disease) on the decision to dine out and, once in a restaurant, whether to order beef. We find that when media coverage of BSE crises is high, people eat out less often, decrease the number of beef orders when eating out, and increase the ordering of other products. Interestingly, we find that these effects only hold for well-known, national chain restaurants and not for local restaurants. We develop and implement a modified double-hurdle model that explicitly takes into account participation (i.e., dine out) and consumption (e.g., number of beef orders) information in estimation of the model. This work extends the product harm crises literature to the case of industry level crises and the context of restaurants. The thesis concludes with a brief chapter on limitations and extensions of the research.

description: Comparison with theory of Casimir force measurements are used to test the gravity force law at ranges from 0.1 to 10 micrometers. The interest of such tests depends crucially on the theoretical evaluation of the Casimir force in realistic experimental configurations. We present the scattering approach which is nowadays the best tool for such an evaluation. We then describe the current status of the comparisons between theory and experiments.

Studies toward the identification of the origin of assembly on cucumber necrosis virus RNA and encapsidation of host RNA
Creators: name: Ghoshal, Kankana
Publisher: name: University of British Columbia
Year: 2015

description: Assembly is one of the major steps in the virus multiplication cycle. Recognition of viral RNA by coat protein (CP) is one means to ensure specific packaging of viral RNA over host RNA for the production of infectious virus particles. Viral RNAs possess specific sequences and/or structures [origin of assembly sequences (OASs)] which serve as high-affinity binding sites for the CP. In this thesis, I aimed to identify the OAS of Cucumber necrosis virus (CNV). Serendipitously, it was found that besides viral RNA, CNV also encapsidates host RNAs albeit to a lower level (~0.1%). Therefore, I extended my research to characterize the host RNAs present in CNV virions and in virus-like particles (VLPs) formed during agro-infiltration with CP. Characterization of encapsidated RNAs showed that both CNV virions and VLPs contained a variety of host RNA species, the most predominant being chloroplast encoded RNAs. Remarkably, certain retrotransposon or retrotransposon-like sequences were among the most efficiently encapsidated nuclear encoded RNAs, indicating that CNV virions may possibly serve as a vehicle for horizontal transmission of retrotransposons to new hosts and thereby significantly influence genome evolution. To my knowledge, this is the first report of a plant virus encapsidating retrotransposon-like sequences and complements the recent findings that Flock house virus, a small icosahedral insect virus, also encapsidates retrotransposons. Interestingly, analysis of the relative encapsidation efficiency of CP mRNA in VLPs was found to be high, indicating that the CNV CP ORF may contain an OAS(s). Towards the identification of an OAS in CNV RNA, a 1.2 kb segment encompassing the 3’ terminus of the replicase ORF and 800 nt of the CP ORF was found to stimulate encapsidation of heterologous chimeric viral RNA during co-infection with CNV. However, smaller portions of this region failed to facilitate encapsidation. Interestingly, two chimeric viral RNAs expressing CNV CP were efficiently encapsidated suggesting that the CP ORF may contain an OAS(s). This result raises the possibility that the microenvironment where virus replication and encapsidation occurs may play a role in the specificity of encapsidation, supporting the involvement of multiple factors in the specificity of CNV RNA assembly.

description: NEWSERA Blueprints for citizen science communication (#citscicomm) with and for quadruple helix stakeholders (citizens and society at large, academic scientists, public sector and policymakers, industry and SMES) and science and data journalists is an instrument that can serve a general audience, including those who are planning to start a citizen science (CS) project, those who want to improve and/or rethink their communication strategies in order to increase specific target audiences, or those who want to enlarge their scope of action by involving the different actors of the quadruple helix model and the media. The road for CS projects establishment and sustainability is long and there are many barriers to be faced. But you are not alone! Together with 39 CS projects from Italy, Spain and Portugal, the NEWSERA Pilots, we have tested the NEWSERA methodology for the co-design, implementation, iterative assessment and validation of communication strategies directed to each of the quadruple helix stakeholders and science and data journalists. This was performed through our #CitSciComm Labs, dedicated to each individual stakeholder, consisting of three rounds of workshops, replicated in each of the participating countries, throughout three years. In this series of five blueprints, NEWSERA brings the learnings of this co-created process together with our pilots, invited stakeholders and science communication experts (NEWSERA Sounding Board) that was complemented with mentoring, capacity building and networking sessions, generating knowledge, recommendations and useful resources. In this blueprint, dedicated to industry and SMEs as target stakeholder, you will find, more in depth, the importance to address this stakeholder, good practices on the co-design of targeted communication plans, elements of co-design, mutual benefits of CS project-stakeholder, and indicators. Furthermore, a description and details of messages, innovative tools, channels and specific case-studies from the NEWSERA Pilots are included. Finally, we shared a series of recommendations to efficiently engage with quadruple helix stakeholders and science and data journalists for wider impact and ensure replicability of the NEWSERA findings and science communication strategies in citizen science projects and beyond.
Antimicrobial efficacy of different calcium hydroxide containing preparations against biofilms at different stages of biofilm development

Publisher: name: University of British Columbia
Year: 2015

description: Objective: To quantify and assess the antibacterial effect of different medicaments on young and aged biofilms, and to modify the medicaments in order to increase their antibacterial effect. Hypotheses: Microbes in aged biofilms grown from a mixture of oral bacteria are more resistant to the antimicrobial activity of calcium hydroxide than microbes in young biofilms. Biofilms are less resistant to calcium hydroxide combined with other antimicrobial agents than to pure calcium hydroxide. Methodology: Collagen coated hydroxyapatite disks were immersed in plaque suspension solution and incubated for one and three weeks to grow young and aged biofilms, respectively. The tested medicaments were calcium hydroxide, iodine potassium iodide, cetrimide, and the following combinations: iodine potassium iodide + cetrimide, calcium hydroxide, calcium hydroxide + iodine potassium iodide, calcium hydroxide + cetrimide, calcium hydroxide + iodine potassium iodide + cetrimide. After exposure to the medicaments for one day, one week, and two weeks, biofilms on disks were stained with a LIVE/DEAD viability stain and imaged using confocal laser scanning microscopy. The three-dimensional reconstructions of the images were done and proportions of green and red fluorescence were measured and statistically analyzed. Results: Aged biofilms were thicker than the young biofilms. All tested medicaments showed reduced antibacterial activity on the aged biofilms compared to young biofilms. Combining iodine potassium iodide to cetrimide had an additive effect and mixed with calcium hydroxide showed stronger antibacterial effect than calcium hydroxide alone. Conclusions: Aged biofilms are more resistant to antibacterial agents than young biofilms. Combining iodine potassium iodide and cetrimide to calcium hydroxide resulted in an antibacterial effect that was stronger than using calcium hydroxide alone.

description: Simple vacuum evaporation technique for deposition of dyes on various solid surfaces has been developed. The method is compatible with conventional solvent-free nanofabrication processing enabling fabrication of nanoscale optoelectronic devices. Thin films of fluorescein were deposited on glass, fluorine-tin-oxide (FTO) coated glass with and without atomically layer deposited (ALD) nanocrystalline 20 nm thick anatase TiO2 coating. Surface topology, absorption and emission spectra of the films depends on their thickness and the material of supporting substrate. On a smooth glass surface the dye initially formes islands before merging into a uniform layer after 5 to 10 monolayers. On FTO covered glass the absorption spectra are similar to fluorescein solution in ethanol. Absorption spectra on ALD-TiO2 is red shifted compared to the film deposited on bare FTO. The corresponding emission spectra at λ = 458 nm excitation show various thickness and substrate dependent features, while the emission of films deposited on TiO2 is quenched due to the effective electron transfer to the semiconductor conduction band.

Hows, whys and but-fors : theorizing, comparing and solution finding within the principle of material contribution to risk in the law of negligence
Creators: name: Caunt, Lachlan
Publisher: name: University of British Columbia
Year: 2015

description: This thesis will provide a significant and original contribution to the scholarship on tort causation. Material contribution to risk is a principle of tort causation; yet has never been applied. It may potentially violate all of the principles that underpin tort causation, whatever those principles may be. Alternately, it may simply be another conventional adaptation of tort causation to avoid manifest injustice. The supposition is that it will fall somewhere between. This thesis contributes to the literature converting this supposition into knowledge. This thesis has three parts. The first seeks to do what few in tort writing do: craft a methodology. The first part compares and contrasts the theory that underpins tort law, the law of negligence, and finally, the theory of causation. Any choice in the latter part of the article is obviously conditioned on which theory explains the actual benefits and harms of such a choice. The second part uses comparison to determine where the Canadian law of material contribution to risk currently rests. By showing the fundamental dissimilarities between the Canadian and UK jurisprudence, this part shows that the two jurisdictions are, and should continue to be, unique. The third part considers two areas of material contribution to risk that are fundamentally unclear. Firstly, circumstances in which material contribution to risk can apply in lieu of the de facto but-for test are, at best, transparent. This section is termed the ‘trigger’ section—and probes when material contribution to risk can be applied instead of the de facto but-for test. Secondly, who is liable for what under material contribution to risk is also unclear. This section is termed apportionment—and determines which liability rule should determine which defendant should be liable for what share of the damages. This thesis makes an original contribution to the literature by defining the underlying theory of causation in negligence through the application of robust methodology; defining the Canadian law of material contribution to risk; and finally, establishing both what the trigger is, and what apportionment should be, in relation to material contribution to risk.

The intensity, impulsiveness and energetics of these events are investigated. We find that, on the average, flares associated both with type IIs and CMEs are more impulsive and more energetic than flares associated with type IIs only (without CME reported), as well as flares accompanied by type IV continua but not type II shocks. From the last two classes, flares with type II bursts (without CMEs reported) are the shortest in duration and the most impulsive.

description: Complex networks can often be decomposed into less complex sub-networks whose structures can give hints about the functional organization of the network as a whole. However, these structural motifs can only tell one part of the functional story because in this analysis each node and edge is treated on an equal footing. In real networks, two motifs that are topologically identical but whose nodes perform very different functions will play very different roles in the network. Here, we combine structural information derived from the topology of the neuronal network of the nematode C. elegans with information about the biological function of these nodes, thus coloring nodes by function. We discover that particular colorations of motifs are significantly more abundant in the worm brain than expected by chance, and have particular computational functions that emphasize the feed-forward structure of information processing in the network, while evading feedback loops. Interneurons are strongly over-represented among the common motifs, supporting the notion that these motifs process and transduce the information from the sensor neurons towards the muscles. Some of the most common motifs identified in the search for significant colored motifs play a crucial role in the system of neurons controlling the worm's locomotion. The analysis of complex networks in terms of colored motifs combines two independent data sets to generate insight about these networks that cannot be obtained with either data set alone. The method is general and should allow a decomposition of any complex network into its functional (rather than topological) motifs as long as both wiring and functional information is available.

description: Due to its high potential for the formation of carbon-carbon bonds, Michael addition reaction is one of the closest reactions to the heart of synthetic organic chemists. Electrochemistry presents a very stimulating and divergent resource for selective oxidation and reduction in organic chemistry, generating activated species, for example radical anions or radical cations. In this review, we try to underscore usefulness of electrogenerated Michael addition reaction with the hope of encouraging synthetic organic chemists to contemplate it, as an efficient and green strategy when it is required in their designed multi-step reaction pathways.
Sociocultural determinants of HIV vulnerabilities among ethnic and religious minority men who have sex with men in North China
Creators: name: Pan, Stephen Warren
Publisher: name: University of British Columbia
Year: 2017

description: BACKGROUND: In China, 29% of new HIV cases are among men who have sex with men (MSM). Sociocultural factors may be influencing the HIV vulnerabilities of certain ethnic and religious minority MSM, but little such research exists in China. This dissertation seeks to understand how ethnicity and religion are shaping HIV vulnerabilities and testing among MSM in China. METHODS: Data were collected in three phases in Beijing and Tianjin, China from January 2013 – April 2014. Participants were self-identified MSM over 18 years old. In phase one, in-depth qualitative interviews were conducted with MSM of various ethnic and religious affiliations (n=41). Interview transcripts were analysed using an interpretive thematic approach. In phase two, findings from phase one informed the design of a structured questionnaire, which was pilot tested in two feedback sessions (n=8). In phase three, the structured questionnaire was used in a clinic-based cross-sectional survey (n=400). Statistical tests were conducted to assess if HIV infection, vulnerability, and testing were correlated with: ethnic and religious affiliation, acculturation, religiosity, and ethnic and religious discrimination. Inter-ethnic and inter-religious sexual partnerships were also assessed. Homonegativity was also assessed as a possible mediating variable between: (a) ethnicity and religion and (b) HIV-related outcomes. RESULTS: Ethnic and religious affiliations profoundly influenced individuals’ social reference groups. Religious social norms, codes of sexual morality, and beliefs in supernatural interventions appear to be inhibiting same-sex sexual behaviours among religious MSM, especially Muslims. Buddhists and ethnic minorities of South China had higher odds of various HIV vulnerabilities. Religiosity appears to have both positive and deleterious influences on HIV vulnerability. Sexual minority religious organisations can provide unique social support. Buddhists, Muslims, and ethnic Hui were more likely to report sex with their own religious and ethnic peers. Homonegativity did not account for any associations between ethnicity and religion and HIV-related outcomes. CONCLUSION: This dissertation is the first study to explicitly explore the intersectionality of ethnicity, religion, sexuality, and HIV vulnerability in China. Findings highlight the ethnic and religious diversity among MSM in China and its salience for HIV prevention. Public health models of conceptualizing ethnocultural difference in China should be re-examined.

Developing a novel heterogeneous three electrode system for a PDMS-based microfluidic electrochemical sensor

description: Biosensors have seen an increased use in recent years as an in situ testing device for various industries such as agriculture, environmental sustainability, food, health, etc. On-site testing devices have an advantage over traditional testing system because they can be used for real-time monitoring and improving the accuracy of time-sensitive detection results. Out of all the industries, the health industry benefits most from in situ devices as point-of-care diagnostic devices. Point-of-care devices are useful tools to quickly diagnose diseases and direct patients’ course of treatment in low-income countries with few resources. In 2014 there were approximately 9.6 million global cases of tuberculosis (TB) and 1.5 million deaths due to TB (caused by the infection of Mycobacterium Tuberculosis [MTB]). Globally, this made TB the second most common cause of death by an infection disease in 2014. With a rising incidence of multi drug-resistant and extensive drug-resistant TB, TB is again becoming a global issue that wealthy countries will likely be unable to ignore. Since transmission is commonly through airborne particulates, early diagnosis and correct treatment of TB are fundamental to not only preventing the spread of the disease, but also eradicating it. Currently, the screening and detection tools that lower resource countries have are limited. Although the MTB genome has been sequenced since 1998, cost-effective, point-of-care, gene-based detection technology has had limited development. Since the integration of MEMS technology to biologically relevant needs in the late 90s there has been much development in creating small, portable detection systems for point-of-care use. Furthermore, this work details the development of a novel heterogeneous 3-material 3-electrode electrochemical sensor in a PDMS based bonded device. This sensor was developed with the intention of integration into a biosensor system. The final 3-electrode system was composed of 3 different materials: Au counter electrode, carbon working electrode, and Ag/AgCl reference electrode. The 3 material 3-electrode system was tested as an electrochemical system by detection of aqueous 5 μM carminic acid in room temperature and post 65◦C heating conditions. Parallel work was done to develop a robust, leak-free bonding method that survived 65◦C heating conditions and preserved electrochemical functionality.

description: Ice shelves play key roles in stabilizing Antarctica’s ice sheets, maintaining its high albedo and returning freshwater to the Southern Ocean. Improved data sets of ice shelf draft and underlying bathymetry are important for assessing ocean–ice interactions and modeling ice response to climate change. The long, narrow Abbot Ice Shelf south of Thurston Island produces a large volume of meltwater, but is close to being in overall mass balance. Here we invert NASA Operation IceBridge (OIB) airborne gravity data over the Abbot region to obtain sub-ice bathymetry, and combine OIB elevation and ice thickness measurements to estimate ice draft. A series of asymmetric fault-bounded basins formed during rifting of Zealandia from Antarctica underlie the Abbot Ice Shelf west of 94°W and the Cosgrove Ice Shelf to the south. Sub-ice water column depths along OIB flight lines are sufficiently deep to allow warm deep and thermocline waters observed near the western Abbot ice front to circulate through much of the ice shelf cavity. An average ice shelf draft of ~200m, 15% less than the Bedmap2 compilation, coincides with the summer transition between the ocean surface mixed layer and upper thermocline. Thick ice streams feeding the Abbot cross relatively stable grounding lines and are rapidly thinned by the warmest inflow. While the ice shelf is presently in equilibrium, the overall correspondence between draft distribution and thermocline depth indicates sensitivity to changes in characteristics of the ocean surface and deep waters.
The Trace Anomaly and Dynamical Vacuum Energy in Cosmology

description: The trace anomaly of conformal matter implies the existence of massless scalar poles in physical amplitudes involving the stress-energy tensor. These poles may be described by a local effective action with massless scalar fields, which couple to classical sources, contribute to gravitational scattering processes, and can have long range gravitational effects at macroscopic scales. In an effective field theory approach, the effective action of the anomaly is an infrared relevant term that should be added to the Einstein-Hilbert action of classical General Relativity to take account of macroscopic quantum effects. The additional scalar degrees of freedom contained in this effective action may be understood as responsible for both the Casimir effect in flat spacetime and large quantum backreaction effects at the horizon scale of cosmological spacetimes. These effects of the trace anomaly imply that the cosmological vacuum energy is dynamical, and its value depends on macroscopic boundary conditions at the cosmological horizon scale, rather than sensitivity to the extreme ultraviolet Planck scale.

description: We describe a simple randomized benchmarking protocol for quantum information processors and obtain a sequence of models for the observable fidelity decay as a function of a perturbative expansion of the errors. We are able to prove that the protocol provides an efficient and reliable estimate of an average error-rate for a set operations (gates) under a general noise model that allows for both time and gate-dependent errors. We determine the conditions under which this estimate remains valid and illustrate the protocol through numerical examples.

Characterization of novel therapeutic targets in chronic myeloid leukemia
Creators: name: Rothe, Katharina
Publisher: name: University of British Columbia

description: The identification of BCR-ABL1 as the key molecular event in chronic myeloid leukemia (CML) has revolutionized treatment opportunities for early phase patients. Imatinib mesylate (IM) and other ABL1 tyrosine kinase inhibitors (TKIs) have been introduced into the clinic with remarkable effects. However, initial and acquired resistance, relapse and in particular, the persistence of CML stem cells upon TKI therapy represent critical challenges and warrant the identification of predictive biomarkers and novel, distinct targets for improved treatment strategies. In this work, I investigated how CML stem and progenitor cells survive TKI therapy through intrinsic and bone marrow (BM) niche-associated mechanisms. I revealed that the core autophagy protease ATG4B, and the focal adhesion protein and serine/threonine kinase Integrin-linked kinase (ILK) play crucial roles in CML, and that they can be successfully targeted with small molecule inhibitors. By comparing the expression of various core autophagy genes and proteins, ATG4B was identified as potential biomarker in CML to predict IM-responders versus IM-nonresponders prior to the initiation of therapy. Furthermore, my studies illustrated that deregulation of ATG4B is critical to autophagy, survival and growth of CML stem and progenitor cells. Inhibition or suppression of ATG4B decreased CML cell viability significantly and sensitized leukemic cells to TKI treatment highlighting ATG4B as a novel target in CML. ILK was identified as a differentially expressed gene between CD34⁺ CML patient cells and healthy donors by RNA-sequencing (RNA-seq) analysis, and the importance of the ILK protein and its kinase functions in mediating TKI responses and resistance in CML stem and progenitor cells was demonstrated by ILK inhibitor (QLT0267) and ILK suppression studies. Moreover, various in vitro and in vivo assays showed that the simultaneous kinase inhibition of ILK and BCR-ABL1 is effective in targeting both leukemic stem and progenitor cells, including quiescent CML cells, and in the presence of stromal cells of the BM microenvironment that make TKI monotherapies ineffective. Overall, these studies provide the first evidence of the importance of ATG4B and ILK in CML, and their potential as novel therapeutic targets for improved combination treatments with TKIs to specifically eliminate CML stem and progenitor cells.

description: Electron transport properties of titanium nanowires were experimentally studied. Below the effective diameter $\lesssim$ 50 nm all samples demonstrated a pronounced broadening of the $R(T)$ dependencies, which cannot be accounted for thermal flcutuations. An extensive microscopic and elemental analysis indicates the absence of structural or/and geometrical imperfection capable to broaden the the $R(T)$ transition to such an extent. We associate the effect with quantum flucutuations of the order parameter.
