description: We use the data for the Hbeta emission-line, far-ultraviolet (FUV) and mid-infrared 22 micron continuum luminosities to estimate star formation rates averaged over the galaxy lifetime for a sample of about 14000 bursting compact star-forming galaxies (CSFGs) selected from the Data Release 12 (DR12) of the Sloan Digital Sky Survey (SDSS). The average coefficient linking and the star formation rate SFR_0 derived from the Hbeta luminosity at zero starburst age is found to be 0.04. We compare s with some commonly used SFRs which are derived adopting a continuous star formation during a period of ~100 Myr, and find that the latter ones are 2-3 times higher. It is shown that the relations between SFRs derived using a geometric mean of two star-formation indicators in the UV and IR ranges and reduced to zero starburst age have considerably lower dispersion compared to those with single star-formation indicators. We suggest that our relations for determination are more appropriate for CSFGs because they take into account a proper temporal evolution of their luminosities. On the other hand, we show that commonly used SFR relations can be applied for approximate estimation within a factor of ~2 of the averaged over the lifetime of the bursting compact galaxy.

description: Clinical genomics is a system of multiple stakeholders and institutions. Yet, studies focusing on the comparative perspectives of these stakeholders are limited. This study engages four groups of professionals (clinical geneticists, genetic counselors, laboratory professionals, and researchers) working in clinical genomics to investigate their perceptions of the benefits and risks of using genomics in Australian healthcare. The study is underpinned by a risk governance approach. For data collection, qualitative semi-structured interviews were used. Our results show that all professionals unanimously identified that the benefit of clinical genomics lies in improving health outcomes for patients. However, the risks associated with delivering this benefit differed by professional category. We found that the further the profession was from the patient (e.g. researcher) the narrower the perceived risks were amongst the individuals interviewed. However, “privacy” as a perceived risk was ranked highly by all professions indicating a shared desire for responsible data governance practices.
A Phase-Field Model for Fluid-Structure-Interaction

description: In this paper, we develop a novel phase-field model for fluid-structure interaction (FSI), that is capable to handle very large deformations as well as topology changes like contact of the solid to the domain boundary. The model is based on a fully Eulerian description of the velocity field in both, the fluid and the elastic domain. Viscous and elastic stresses in the Navier-Stokes equations are restricted to the corresponding domains by multiplication with their characteristic functions. To obtain the elastic stress, an additional Oldroyd-B - like equation is solved. Thermodynamically consistent forces are derived by energy variation. The convergence of the derived equations to the traditional sharp interface formulation of fluid-structure interaction is shown by matched asymptotic analysis. The model is evaluated in a challenging benchmark scenario of an elastic body traversing a fluid channel. A comparison to reference values from Arbitrary Lagrangian Eulerian (ALE) simulations shows very good agreement. We highlight some distinct advantages of the new model, like the avoidance of re-triangulations and the stable inclusion of surface tension. Further, we demonstrate how simple it is to include contact dynamics into the model, by simulating a ball bouncing off a wall. We extend this scenario to include adhesion of the ball, which to our knowledge, cannot be simulated with any other FSI model. While we have restricted simulations to fluid-structure interaction, the model is capable to simulate any combination of viscous fluids, visco-elastic fluids and elastic solids.

description: Timely effective regulation of genetic advances presents a challenge for justice systems. We used a 51-item battery to examine views on major genetics-related issues of those at the forefront of regulating this area – Supreme Court judges (N = 73). We also compared their views with those of other justice stakeholders (N = 210) from the same country (Romania). Judges showed greater endorsement and less variability in views on the use of genetic data and technologies than the other groups. The agreement among the judges was strikingly strong for some controversial issues, including gene editing; patenting of genetic findings; and the State using genetic information for crime prevention. Judges and other lawyers recognized the need for amending the relevant laws. Without appropriate regulation, genetic science has a risk of propelling inequality rather than fulfilling its promise to improve people’s lives.

description: Collisionless plasmas, mostly present in astrophysical and space environments, often require a kinetic treatment as given by the Vlasov equation. Unfortunately, the six-dimensional Vlasov equation can only be solved on very small parts of the considered spatial domain. However, in some cases, e.g. magnetic reconnection, it is sufficient to solve the Vlasov equation in a localized domain and solve the remaining domain by appropriate fluid models. In this paper, we describe a hierarchical treatment of collisionless plasmas in the following way. On the finest level of description, the Vlasov equation is solved both for ions and electrons. The next courser description treats electrons with a 10-moment fluid model incorporating a simplified treatment of Landau damping. At the boundary between the electron kinetic and fluid region, the central question is how the fluid moments influence the electron distribution function. On the next coarser level of description the ions are treated by an 10-moment fluid model as well. It may turn out that in some spatial regions far away from the reconnection zone the temperature tensor in the 10-moment description is nearly isotopic. In this case it is even possible to switch to a 5-moment description. This change can be done separately for ions and electrons. To test this multiphysics approach, we apply this full physics-adaptive simulations to the Geospace Environmental Modeling (GEM) challenge of magnetic reconnection.

description: The stability of the Maxwellian of the Boltzmann equation with a large amplitude external potential $Φ$ has been an important open problem. In this paper, we resolve this problem with a large $C3-$potential in a periodic box $\mathbb{T}^d$, $d \geq 3$. We use [1] in $L^p-L^{\infty}$ framework to establish the well-posedness and the $L^{\infty}-$stability of the Maxwellian $μ_E(x,v)=\exp\{-\frac{|v|^2}{2}-Φ(x)\}$.

description: DAMPE (DArk Matter Particle Explorer) is a spaceborne high-energy cosmic ray and gamma-ray detector, successfully launched in December 2015. It is designed to probe astroparticle physics in the broad energy range from few GeV to 100 TeV. The scientific goals of DAMPE include the identification of possible signatures of Dark Matter annihilation or decay, the study of the origin and propagation mechanisms of cosmic-ray particles, and gamma-ray astronomy. DAMPE consists of four sub-detectors: a plastic scintillator strip detector, a Silicon-Tungsten tracKer-converter (STK), a BGO calorimeter and a neutron detector. The STK is composed of six double layers of single-sided silicon micro-strip detectors interleaved with three layers of tungsten for photon conversions into electron-positron pairs. The STK is a crucial component of DAMPE, allowing to determine the direction of incoming photons, to reconstruct tracks of cosmic rays and to estimate their absolute charge (Z). We present the in-flight performance of the STK based on two years of in-flight DAMPE data, which includes the noise behavior, signal response, thermal and mechanical stability, alignment and position resolution.

On the Pseudo-Schrödinger Equation approximation of the Transfer-Integral operator for 1-dimensional DNA models

description: The Transfer-Integral (TI) operator is a powerful method to investigate the statistical physics of 1-dimensional models, like those used to describe DNA denaturation. At the cost of a certain number of approximations, the TI equation can be reduced to a Pseudo-Schrödinger Equation (PSE), according to which the DNA sequence is equivalent to a point particle moving in a potential well. In this paper, I check the validity of the standard PSE approximation for two different 1-dimensional DNA models, and show that it fails to provide correct results for both of them. I then propose a generalized PSE, which works well for one of the two models. Finally, I discuss the particle description of DNA denaturation that is derived from this generalized PSE.

Recent trends in cancer screening uptake amongst immigrants in Canada between 2005-2015
Creators: name: Moustaqim-Barrette, Amina
Publisher: name: University of British Columbia

description: INTRODUCTION: In 2016 alone, an estimated 202,400 Canadians developed cancer, and 78,800 died of the disease. In Canada, the use of reliable screening techniques for three types of cancer – breast, cervical, and colorectal – could help decrease cancer burden on a national scale. However, the literature also suggests that cancer screening uptake may be hampered in specific subpopulations, including among Canadian immigrants. The current study seeks to examine the association between immigration and breast, cervical, and colorectal cancer uptake. METHODS: This analysis uses ten years of data, 2005 – 2015, from the Canadian Community Health Survey (CCHS). Survey cycles were pooled to create an average pseudo-population and a bootstrap resampling technique was used to estimate variance. Age and sex-standardized rates were used to examine breast, cervical, and colorectal cancer screening rates between recent immigrants, long-term immigrants, and Canadian-born individuals. Multivariate logistic regression was used to evaluate the impact of immigration status on non-adherence and never screening, as well as to look at differences among immigrant subgroups and between screening years. RESULTS: Results indicate that recent immigrants (residing in Canada for 0 – 9 years) may have higher odds of never screening and non-adherence for breast cancer screening (AOR 2.15 (CI 0.89 – 5.20) and AOR 1.73 (CI 0.90 – 3.33), respectively), for cervical cancer screening (AOR 1.27 (CI 0.70 – 2.29) and AOR 1.47 (CI 0.98 – 2.21), respectively), and for colorectal cancer screening (AOR 1.75 (CI 1.11 – 2.77) and AOR 1.54 (CI 0.98 – 2.44), respectively) compared to Canadian-born individuals, although most results were not statistically significant. Importantly, several sociodemographic factors were significantly associated with never screening and non-adherence, including higher income and higher educational attainment. There was some evidence of differential uptake in immigrants by world region of birth and racial origin. The risk of non-adherence and never-screening among immigrants did not change significantly between 2005 – 2015. CONCLUSIONS: This study indicates that immigrants residing in Canada for 9 years or less are at higher risk of never screening and non-adherence to breast, cervical, and colorectal cancer screening guidelines. This study supports targeted interventions to increase preventative cancer screening use among newcomers to Canada.

description: Autonomous robotic systems are complex, hybrid, and often safety-critical; this makes their formal specification and verification uniquely challenging. Though commonly used, testing and simulation alone are insufficient to ensure the correctness of, or provide sufficient evidence for the certification of, autonomous robotics. Formal methods for autonomous robotics has received some attention in the literature, but no resource provides a current overview. This paper systematically surveys the state-of-the-art in formal specification and verification for autonomous robotics. Specially, it identifies and categorises the challenges posed by, the formalisms aimed at, and the formal approaches for the specification and verification of autonomous robotics.

description: IPT 2019 Problem 2 Yut Technical University of Denmark: When making a choice or playing a game, we employ methods such as tossing a coin, rolling dice, or, throwing a Yut stick. Yut sticks are roughly half-cylindrical in shape and as such it is much easier to bias the outcome of up vs. down than it is for a coin or dice. If the floor is soft, then the stick is likely to have its flat side up, as the round side has a larger surface. If the floor is hard and the stick is ‘rolled’, the stick is likely to have its round side up. How does the probability of the outcomes depend on the relevant parameters?

description: Implementing a managed language efficiently is hard, and it is becoming more difficult as the complexity of both language-level design and machines is increasing. To make things worse, current approaches to language implementations make them prone to inefficiency as well. A high-quality monolithic language implementation demands extensive expertise and resources, but most language implementers do not have those available so their implementations suffer from poor performance. Alternatively, implementers may build on existing frameworks. However, the back-end frameworks often offer abstractions that are mismatched to the language, which either bounces back the complexity to the implementers or results in inefficiency. Want et al. proposed micro virtual machines as a solution to address this issue. Micro VMs are explicitly minimal and efficient. Micro VMs support high-performance implementation of managed languages by providing key abstractions, i.e. code execution, garbage collection, and concurrency. The abstractions are neutral across client languages, and general and flexible to different implementation strategies. These constraints impose interesting challenges on a micro VM implementation. Prior to this work, no attempt had been made to efficiently implement a micro VM. My thesis is that key abstractions provided by a micro virtual machine can be implemented efficiently to support client languages. By exploring the efficient implementation of micro virtual machines, we present a concrete implementation, Zebu VM, which implements the Mu micro VM specification. The thesis addresses three critical designs in Zebu, each mapping to a key abstraction that micro virtual machines provide, and establishes their efficiency: 1) demonstrating the benefits of utilizing a modern language that focuses on safety to implement a high performance garbage collector, 2) analysing the design space of yieldpoint mechanism for thread synchronization, and 3) building a micro compiler under the specific constraints imposed by micro virtual machines, i.e. minimalism, efficiency and flexibility. This thesis is a proof of concept and an initial proof of performance to establish micro virtual machines as an efficient substrate for managed language implementation. It encourages the approach of building language implementations with micro virtual machines, and reinforces the hope that Mu will be a suitable back-end target. The thesis discusses the efficient implementation for micro virtual machines, but illustrates broader topics useful in general virtual machine design and construction.

description: It has long been known that the existence of certain superquantum nonlocal correlations would cause communication complexity to collapse. The absurdity of a world in which any nonlocal binary function could be evaluated with a constant amount of communication in turn provides a tantalizing way to distinguish quantum mechanics from incorrect theories of physics; the statement "communication complexity is nontrivial" has even been conjectured to be a concise information-theoretic axiom for characterizing quantum mechanics. We directly address the viability of that perspective with two results. First, we exhibit a nonlocal game such that communication complexity collapses in any physical theory whose maximal winning probability exceeds the quantum value. Second, we consider the venerable CHSH game that initiated this line of inquiry. In that case, the quantum value is about 0.85 but it is known that a winning probability of approximately 0.91 would collapse communication complexity. We provide evidence that the 0.91 result is the best possible using a large class of proof strategies, suggesting that the communication complexity axiom is insufficient for characterizing CHSH correlations. Both results build on new insights about reliable classical computation. The first exploits our formalization of an equivalence between amplification and reliable computation, while the second follows from an upper bound on the threshold for reliable computation with formulas of noisy XOR and AND gates.

description: In this paper, we investigate how it is possible to define a new class of lattice gauge models based on a dualization procedure of a previous generalization of the Kitaev Quantum Double Models. In the case of this previous generalization that will be used as a basis, it was defined by adding new qudits (which were denoted as matter fields in reference to some works) to the lattice vertices with the intention of, for instance, interpreting its models as Kitaev Quantum Double Models coupled with Potts ones. Now, with regard to the generalization that we investigate here, which we want to define as the dual of this previous one, these new qudits were added to the lattice faces. And as the coupling between gauge and matter qudits of the previous generalization was performed by a gauge group action, we show that the dual behaviour of these two generalizations was achieved by coupling these same qudits in the second one through a gauge group co-action homomorphism. One of the most striking dual aspects of these two generalizations is that, in both, part of the quasiparticles that were inherited from the Kitaev Quantum Double Models become confined when these action and co-action are non-trivial. But the big news here is that, in addition to the group homomorphism (that defines this gauge group co-action) allows us to classify all the different models of this second generalization, this same group homomorphism also suggests that all these models can be interpreted as two-dimensional restrictions of the $ 2 $-lattice gauge theories.

description: This paper studies Emerton's Jacquet module functor for locally analytic representations of p-adic reductive groups. When P is a parabolic subgroup whose Levi factor M is not commutative, we show that passing to an isotypical subspace for the derived subgroup of M gives rise to essentially admissible locally analytic representations of the torus Z(M), which have a natural interpretation in terms of rigid geometry. We use this to extend Emerton's representation-theoretic construction of eigenvarieties by constructing eigenvarieties interpolating automorphic representations whose local components at p are not necessarily principal series.

description: ABRIDGED-This paper presents the first direct estimate of the 3D clustering properties of far-infrared sources up to z~3. This has been possible thanks to the Pacs Evolutionary Probe (PEP) survey of the GOODS South field performed with the PACS instrument onboard the Herschel Satellite. An analysis of the two-point correlation function over the whole redshift range spanned by the data reports for the correlation length, r_0~6.3 Mpc and r_0~6.7 Mpc, respectively at 100um and 160um, corresponding to dark matter halo masses M>~10^{12.4} M_sun. Objects at z~2 instead seem to be more strongly clustered, with r_0~19 Mpc and r_0~17 Mpc in the two considered PACS channels. This dramatic increase of the correlation length between z~1 and z~2 is connected with the presence of a wide, M>~10^{14} M_sun, filamentary structure which includes more than 50% of the sources detected at z~2. An investigation of the properties of such sources indicates the possibility for boosted star-forming activity in those which reside within the overdense environment with respect of more isolated galaxies found in the same redshift range. Lastly, we also present our results on the evolution of the relationship between luminous and dark matter in star-forming galaxies between z~1 and z~2. We find that the increase of (average) stellar mass in galaxies between z~1 and z~2 is about a factor 10 lower than that of the dark matter haloes hosting such objects ([z~1]/[z~2] ~ 0.4 vs M_{halo}[z~1]/M_{halo}[z~2] ~ 0.04). Our findings agree with the evolutionary picture of downsizing whereby massive galaxies at z~2 were more actively forming stars than their z~1 counterparts, while at the same time contained a lower fraction of their mass in the form of luminous matter.

"You're doing it wrong" : skateboarding, gender and the right to the city
Creators: name: Gray, Kerria
Publisher: name: University of British Columbia
Year: 2019

description: My research focuses on skateboarding as a youthful and often gendered means of negotiating public and cultural space. Much of the academic literature sees the act of skateboarding as having transgressive potential in relation to public space. I use this body of work as a starting point from which to explore how class, race, sexuality and especially gender complicate the seemingly progressive relationship between skateboarding and public space. How do those publics who have struggled and continue to struggle for power, safety, and mobility in the public sphere (with a focus on women and non-binary people) engage with this struggle through their participation in skateboarding? And through what means are women and non-binary skaters creating space for themselves within the homogenous and sometimes exclusionary culture of skateboarding itself? Framed through theories of public space (Lefebvre, 1991; Borden, 2001; Mitchell, 1995; Wilson, 1992; Day, 2007) and youth, gender, and resistance (Beal, 1995), my paper explores the contradictory ways that skateboarding both reproduces and provides a means to resist hegemonic discourses. Via an analysis of 10 interviews with skateboarders in Vancouver, BC, a number of media interviews of professional woman skateboarders accessed online, and field observations, I analyze how non-dominant identities find belonging in skateboarding and how skateboarding affects their interactions in and with public space. The women and non-binary skateboarders I spoke with and researched had all at some point overcome external and internalized narratives about women’s limitations when it comes to physical ability and risk, as well as about women’s legitimacy as skateboarders. In conclusion I find that women and non-binary skateboarders negotiate belonging in public space through the use of a variety of gender presentations, the creation of female-only and female-run spaces, the seeking out of female role models, and through the creation and consumption of skateboarding media for and by women.

description: On the search of lightweight lightning protection materials that can be used as part of lightning protection systems, we investigate some types of electroconductive fabrics by applying several lightning impulse currents in laboratory. Samples of four commercially available electroconductive textiles were analyzed, two rip-stop, a plain-weave, a nonwoven, and additionally a carbon-impregnated polymeric film. Under laboratory conditions, each sample was subjected to several lengthwise subsequent lightning-like currents of 8/20 us standard waveform, recording both voltage and current signals. Optical and scanning electron microscope observations were performed after tests, revealing some patterns or morphological changes on the fabric surface. Despite these changes, the investigated conductive textiles withstand the several lightning impulse currents applied. Results suggest that some conductive fabrics could be used in personal mobile shelters, to protect human beings against the earth potential rise caused by a close lightning discharge.

description: A large anomalous Hall effect (AHE) has been observed in ferromagnetic $\textrm{Fe}_3\textrm{Sn}_2$ with breathing kagome bilayers. To understand the underlying mechanism for this, we investigate the electronic structure of $\textrm{Fe}_3\textrm{Sn}_2$ by angle-resolved photoemission spectroscopy (ARPES). In particular, we use both vacuum ultraviolet light (VUV) and soft x ray (SX), which allow surface-sensitive and relatively bulk-sensitive measurements, respectively, and distinguish bulk states from surface states, which should be unlikely related to the AHE. While VUV-ARPES observes two-dimensional bands mostly due to surface states, SX-ARPES reveals three-dimensional band dispersions with a periodicity of the rhombohedral unit cell in the bulk. Our data show a good consistency with a theoretical calculation based on density functional theory, suggesting a possibility that $\textrm{Fe}_3\textrm{Sn}_2$ is a magnetic Weyl semimetal.

description: We report on the study of the linear and circular magneto-gyrotropic photogalvanic effect (MPGE) in GaAs/AlGaAs quantum well structures. Using the fact that in such structures the Landé-factor g* depends on the quantum well (QW) width and has different signs for narrow and wide QWs, we succeeded to separate spin and orbital contributions to both MPGEs. Our experiments show that, for most quantum well widths, the PGEs are mainly driven by spin-related mechanisms, which results in a photocurrent proportional to the g* factor. In structures with a vanishingly small g* factor, however, linear and circular MPGE are also detected, proving the existence of orbital mechanisms.

description: In this paper, we consider the weighted online set k-multicover problem. In this problem, we have a universe V of elements, a family S of subsets of V with a positive real cost for every set in S and a "coverage factor" (positive integer) k. A subset of elements are presented online in an arbitrary order. When each element, say i, is presented, we are also told the collection of all (at least k) sets and their costs to which i belongs and we need to select additional sets from these sets containing i, if necessary, such that our collection of selected sets contains at least k sets that contain the element i. The goal is to minimize the total cost of the selected sets (our algorithm and competitive ratio bounds can be extended to the case when a set can be selected at most a pre-specified number of times instead of just once; we do not report these extensions for simplicity and also because they have no relevance to the biological applications that motivated our work). In this paper, we describe a new randomized algorithm for the online multicover problem based on a randomized version of the winnowing approach of Littlestone. This algorithm generalizes and improves some earlier results by N. Alon, B. Awerbuch, Y. Azar, N. Buchbinder, and J. Naor. We also discuss lower bounds on competitive ratios for deterministic algorithms for general $k$.
