description: In this contribution we summarize recent progress in understanding the shear viscosity of strongly correlated dilute Fermi gases. We discuss predictions from kinetic theory, and show how these predictions can be tested using recent experimental data on elliptic flow. We find agreement between theory and experiments in the high temperature regime $T\gg T_F$, where $T_F$ is the the temperature where quantum degeneracy effects become important. In the low temperature regime, $T\sim T_F$, the strongest constraints on the shear viscosity come from experimental studies of the damping of collective modes. These experiments indicate that $η/s\lsim 0.5\hbar/k_B$, where $η$ is the shear viscosity and $s$ is the entropy density.

description: The European Space Agency's Rosetta spacecraft, en route to a 2014 encounter with comet 67P/Churyumov-Gerasimenko, made a gravity assist swing-by of Mars on 25 February 2007, closest approach being at 01:54UT. The Alice instrument on board Rosetta, a lightweight far-ultraviolet imaging spectrograph optimized for in situ cometary spectroscopy in the 750-2000 A spectral band, was used to study the daytime Mars upper atmosphere including emissions from exospheric hydrogen and oxygen. Offset pointing, obtained five hours before closest approach, enabled us to detect and map the HI Lyman-alpha and Lyman-beta emissions from exospheric hydrogen out beyond 30,000 km from the planet's center. These data are fit with a Chamberlain exospheric model from which we derive the hydrogen density at the 200 km exobase and the H escape flux. The results are comparable to those found from the the Ultraviolet Spectrometer experiment on the Mariner 6 and 7 fly-bys of Mars in 1969. Atomic oxygen emission at 1304 A is detected at altitudes of 400 to 1000 km above the limb during limb scans shortly after closest approach. However, the derived oxygen scale height is not consistent with recent models of oxygen escape based on the production of suprathermal oxygen atoms by the dissociative recombination of O2+.

description: Previous work has shown that robot navigation systems that employ an architecture based upon the idiotypic network theory of the immune system have an advantage over control techniques that rely on reinforcement learning only. This is thought to be a result of intelligent behaviour selection on the part of the idiotypic robot. In this paper an attempt is made to imitate idiotypic dynamics by creating controllers that use reinforcement with a number of different probabilistic schemes to select robot behaviour. The aims are to show that the idiotypic system is not merely performing some kind of periodic random behaviour selection, and to try to gain further insight into the processes that govern the idiotypic mechanism. Trials are carried out using simulated Pioneer robots that undertake navigation exercises. Results show that a scheme that boosts the probability of selecting highly-ranked alternative behaviours to 50% during stall conditions comes closest to achieving the properties of the idiotypic system, but remains unable to match it in terms of all round performance.

description: We present a method for subtracting point sources from interferometric radio images via forward modeling of the instrument response and involving an algebraic nonlinear minimization. The method is applied to simulated maps of the Murchison Wide-field Array but is generally useful in cases where only image data are available. After source subtraction, the residual maps have no statistical difference to the expected thermal noise distribution at all angular scales, indicating high effectiveness in the subtraction. Simulations indicate that the errors in recovering the source parameters decrease with increasing signal-to-noise ratio, which is consistent with the theoretical measurement errors. In applying the technique to simulated snapshot observations with the Murchison Wide-field Array, we found that all 101 sources present in the simulation were recovered with an average position error of 10 arcsec and an average flux density error of 0.15%. This led to a dynamic range increase of approximately 3 orders of magnitude. Since all the sources were deconvolved jointly, the subtraction was not limited by source sidelobes but by thermal noise. This technique is a promising deconvolution method for upcoming radio arrays with a huge number of elements, and a candidate for the difficult task of subtracting foreground sources from observations of the 21 cm neutral Hydrogen signal from the epoch of reionization.

description: Software development increasingly became part of the daily work of many researchers in science and engineering. They are faced with software engineering challenges for which they are not trained. In 2005, the German Aerospace Center (DLR) started the "DLR Software Engineering Initiative" to support their researchers addressing these challenges. One of the initiative’s core element is to setup and establish an active software engineering community within DLR. Improving the activities of the DLR software engineering initiative is an ongoing challenge. For this purpose, a good understanding of the software engineering community within DLR is required. We present insights about the DLR software engineering community through an analysis of the participation at the annual software engineering knowledge exchange workshops. These workshops can be considered as the annual software engineering community event and offer therefore a good starting point to analyze the community. The results show that the analyzed active part of the community consists of a small, stable core group, some non-regular visitors, and one-time participants. Participants from nearly all DLR locations attend the workshops. Most participants of the workshop series originate from large research-oriented DLR sites. The workshop topic seems to influence the workshop attendance. The results indicate that we need to do the ongoing topic specialization carefully to cultivate the established core member group.

description: Hundreds of gamma-ray burst (GRB) optical light curves have been measured since the discovery of optical afterglows. However, even after nearly 7 years of operation of the Swift Observatory, only a handful of measurements have been made soon (within a minute) after the gamma ray signal. This lack of early observations fails to address burst physics at short time scales associated with prompt emissions and progenitors. Because of this lack of sub-minute data, the characteristics of the rise phase of optical light curve of short-hard type GRB and rapid-rising GRB, which may account for ~30% of all GRB, remain practically unknown. We have developed methods for reaching sub-minute and sub-second timescales in a small spacecraft observatory. Rather than slewing the entire spacecraft to aim the optical instrument at the GRB position, we use rapidly moving mirror to redirect our optical beam. As a first step, we employ motorized slewing mirror telescope (SMT), which can point to the event within 1s, in the UFFO Pathfinder GRB Telescope onboard the Lomonosov satellite to be launched in Nov. 2011. UFFO's sub-minute measurements of the optical emission of dozens of GRB each year will result in a more rigorous test of current internal shock models, probe the extremes of bulk Lorentz factors, provide the first early and detailed measurements of fast-rise GRB optical light curves, and help verify the prospect of GRB as a new standard candle. We will describe the science and the mission of the current UFFO Pathfinder project, and our plan of a full-scale UFFO-100 as the next step.

description: A simple and novel method to fabricate and miniaturize surface and sub-surface micro-structures and micro-patterns in glassy carbon is proposed and demonstrated. An aqueous resorcinol-formaldehyde (RF) sol is employed for micro-molding of the master-pattern to be replicated, followed by controlled drying and pyrolysis of the gel to reproduce an isotropically shrunk replica in carbon. The miniaturized version of the master-pattern thus replicated in carbon is about one order of magnitude smaller than original master by repeating three times the above cycle of molding and drying. The micro-fabrication method proposed will greatly enhance the toolbox for a facile fabrication of a variety of Carbon-MEMS and C-microfluidic devices.

Relational Nations : trading and sharing ethos for Indigenous food sovereignty on Vancouver Island.
Creators: name: Manson, Johnnie
Publisher: name: University of British Columbia
Year: 2016

description: This thesis explores how Indigenous conceptualizations of being and place influence the food trading and sharing behavior of Indigenous people on Vancouver Island. Chapter 1 utilizes critical theory to explore how historically and contemporarily Indigenous nations and people practiced a relational politics where political activity and subjectivity is nested within the tenets of relationality, respect, beneficial reciprocity, and responsibility. Chapter 1 demonstrates that Canada utilized science and rationalism to assert sovereignty and jurisdiction over Indigenous lands, nations, and people. This process altered Indigenous conceptualizations of political subjectivity. Chapter 1 conducts a theoretical exegesis of state conceptualizations of sovereignty, which reveals how food-based politics can be alternately conceptualized and enacted. That is, I argue for a relational politics oriented explicitly towards recognizing, learning from, and incorporating the concerns of the most vulnerable members of Indigenous communities – human and nonhuman – as a mechanism for relational self-determination. In Chapter 2 I analyze the trading and sharing practices of 14 Indigenous people in rural and urban Vancouver Island using an Indigenous research paradigm, qualitative research methods, and critical theory as a mode of analysis. Chapter 2 demonstrates that Indigenous trading and sharing behavior is influenced by ancestral conceptualizations of place and that enactment of these place-based worldviews changes to fit the social context in which Indigenous people find themselves. Indigenous trading and sharing behavior enables Indigenous people to fulfill relational obligations to community, each other, and their non-human kin. Hence, food trading and sharing is a mechanism for relational politics and is used by Indigenous traders and sharers to engage with, cope, and overcome dominant conceptualizations of political subjectivity. In Chapter 3, I reflect on what I have learned from Indigenous traders and sharers, and situate their stories and propositions within a broader dialogue with Indigenous and non-Indigenous social theorists on the meaning of relationships, value, and political subjectivity.

Our results show that one can control properties of nonlinear optical absorption and nonlinear optical rectification of a nanoring by tuning outer and inner radius.

description: This research investigated the simulation model behaviour of a traditional and combined discrete event as well as agent based simulation models when modelling human reactive and proactive behaviour in human centric complex systems. A departmental store was chosen as human centric complex case study where the operation system of a fitting room in WomensWear department was investigated. We have looked at ways to determine the efficiency of new management policies for the fitting room operation through simulating the reactive and proactive behaviour of staff towards customers. Once development of the simulation models and their verification had been done, we carried out a validation experiment in the form of a sensitivity analysis. Subsequently, we executed a statistical analysis where the mixed reactive and proactive behaviour experimental results were compared with some reactive experimental results from previously published works. Generally, this case study discovered that simple proactive individual behaviour could be modelled in both simulation models. In addition, we found the traditional discrete event model performed similar in the simulation model output compared to the combined discrete event and agent based simulation when modelling similar human behaviour.

description: Swimming microorganisms rely on effective mixing strategies to achieve efficient nutrient influx. Recent experiments, probing the mixing capability of unicellular biflagellates, revealed that passive tracer particles exhibit anomalous non-Gaussian diffusion when immersed in a dilute suspension of self-motile Chlamydomonas reinhardtii algae. Qualitatively, this observation can be explained by the fact that the algae induce a fluid flow that may occasionally accelerate the colloidal tracers to relatively large velocities. A satisfactory quantitative theory of enhanced mixing in dilute active suspensions, however, is lacking at present. In particular, it is unclear how non-Gaussian signatures in the tracers' position distribution are linked to the self-propulsion mechanism of a microorganism. Here, we develop a systematic theoretical description of anomalous tracer diffusion in active suspensions, based on a simplified tracer-swimmer interaction model that captures the typical distance scaling of a microswimmer's flow field. We show that the experimentally observed non-Gaussian tails are generic and arise due to a combination of truncated Lévy statistics for the velocity field and algebraically decaying time correlations in the fluid. Our analytical considerations are illustrated through extensive simulations, implemented on graphics processing units to achieve the large sample sizes required for analyzing the tails of the tracer distributions.

description: In this article, a novel fluorescent probe 2-[4-(4-Amino-benzenesulfonyl)-phenyl]-6-bromo-benzo[de]isoquinoline-1,3-dione (L) based on aggregation-caused quenching (ACQ)-type naphthalimide was designed and synthesized, which adopt twisted molecular conformation. The probe exhibited high sensitivity and selectivity for 2,4,6-trinitrophenol (TNP) in aqueous medium. In addition, the fluorescence changes induced by TNP exhibit a sharp contrast where the visual fluorescence color of L changed from grass yellow to blackish green under UV-lamp irradiation upon the addition of TNP to L solution. The detection limit of L for TNP could reach as low as 0.127 μM. The emission quenching mechanisms of the sensing properties of L toward TNP were preliminarily studied as well. These results demonstrate that L can serve as an excellent sensor for TNP through a luminescence quenching process.

description: We present the first 2.5-D MHD simulations of protostellar jets that include both the region in which the jet is launched magnetocentrifugally at scale lengths $<0.1$ AU, and where the propagating jet is observed at scale lengths $>10^3$ AU. These simulations, performed with the new AMR-MHD code AZEuS, reveal interesting relationships between conditions at the disc surface, such as the magnetic field strength, and direct observables such as proper motion, jet rotation, jet radius, and mass flux. By comparing these quantities with observed values, we present direct numerical evidence that the magnetocentrifugal launching mechanism is capable, by itself, of launching realistic protostellar jets.

Novel antimicrobial peptide coating to prevent catheter-associated urinary tract infections
Creators: name: Lo, Joey Chor Yee
Publisher: name: University of British Columbia
Year: 2016

description: Introduction: Urinary catheters provide ideal surfaces for bacterial biofilm formation, being a major factor for hospital-acquired infections. With increased antibiotic resistance, there is a push for non-antibiotic-based measures to prevent catheter-associated urinary tract infections (CAUTI). I pursue the use of polymer-linked, broad-spectrum, host-defense-based antimicrobial peptides (AMPs) as novel catheter coatings. Here, I present the efficacy of tethered AMPs against common uropathogens both in vitro and in vivo. Materials and Methods: Peptides E6, Tet20, Tet26, and Kai13 were linked to surfaces using polymer brushes PDMA, PMPC, and PMPDSAH. All peptides were chosen based on their antimicrobial activity and biocompatibility as suggested by previously published papers. Antimicrobial activity of each coating was determined in vitro via colony counts 6 hours post-exposure to uropathogens. The in vivo efficacy of AMP coatings was also tested using a clinically relevant CAUTI mouse model; bladders of mice were catheterized percutaneously under ultrasound guidance, and 50 μL of 5E+5 CFU/mL P. aeruginosa was instilled. Indwelling polyurethane catheters and urine were collected after 7 days for examination of bacterial adherence and growth. Results: The most effective peptide-brush combination was E6-PDMA, decreasing bacterial adhesion and planktonic growth by up to 94.1% and 63.8%, respectively based on in vitro data. In vivo results look even more promising; the coating decreased bacterial adhesion by up to 99.9958% and planktonic growth by 99.8660% in comparison to untreated mice. Conclusions: Based on our in vitro and in vivo data, E6-PDMA coatings may effectively prevent CAUTI. Further testing of these novel coatings against more common uropathogens as well as tests to confirm the safety of such coatings will be important.

description: In this paper we consider the eigenvalue problem consisting of the equation -u" = \la r u, \quad \text{on $(-1,1)$}, where $r \in C^1[-1,1], \ r>0$ and $\la \in \R$, together with the multi-point boundary conditions u(\pm 1) = \sum^{m^\pm}_{i=1} \al^\pm_i u(η^\pm_i), where $m^\pm \ge 1$ are integers, and, for $i = 1,...,m^\pm$, $\al_i^\pm \in \R$, $η_i^\pm \in [-1,1]$, with $η_i^+ \ne 1$, $η_i^- \ne -1$. We show that if the coefficients $\al_i^\pm \in \R$ are sufficiently small (depending on $r$) then the spectral properties of this problem are similar to those of the usual separated problem, but if the coefficients $\al_i^\pm$ are not sufficiently small then these standard spectral properties need not hold. The spectral properties of such multi-point problems have been obtained before for the constant coefficient case ($r \equiv 1$), but the variable coefficient case has not been considered previously (apart from the existence of `principal' eigenvalues). Some nonlinear multi-point problems are also considered. We obtain a (partial) Rabinowitz-type result on global bifurcation from the eigenvalues, and various nonresonance conditions for existence of general solutions and also of nodal solutions --- these results rely on the spectral properties of the linear problem.

description: Citrus trees can be reproduced through both seeds and vegetative methods. The majority of citrus species, such as mandarins, sweet oranges, limes, lemons, grapefruits, tangerines, and tangelos, are polyembryonic, while temple and pummelo are monoembryonic. While nucellar seedlings from polyembryonic citrus species remain true to their type, vegetative propagation is the preferred method to ensure consistent quality, regular fruit production, and early maturity. In some regions like the NEH and Coorg regions of India, seedlings are used for limes and mandarins. Limes and lemons are typically propagated through cuttings or layering. However, in most areas, citrus trees are created by budding a desired scion variety onto a selected seedling rootstock, which provides disease resistance, high yield, and a long tree lifespan.

description: We prove approach to thermal equilibrium for the fully Hamiltonian dynamics of a dynamical Lorentz gas, by which we mean an ensemble of particles moving through a $d$-dimensional array of fixed soft scatterers that each possess an internal harmonic or anharmonic degree of freedom to which moving particles locally couple. We establish that the momentum distribution of the moving particles approaches a Maxwell-Boltzmann distribution at a certain temperature $T$, provided that they are initially fast and the scatterers are in a sufficiently energetic but otherwise arbitrary stationary state of their free dynamics--they need not be in a state of thermal equilibrium. The temperature $T$ to which the particles equilibrate obeys a generalized equipartition relation, in which the associated thermal energy $k_{\mathrm B}T$ is equal to an appropriately defined average of the scatterers' kinetic energy. In the equilibrated state, particle motion is diffusive.
Cannabis use and perpetration of intimate partner violence : testing a spurious effects model
Creators: name: Crosby, Kimberly Anne
Publisher: name: University of British Columbia
Year: 2016

description: This thesis examined the plausibility of a spurious effects model of the cannabis and intimate partner violence relationship in undergraduate students (Study 1), inpatients in a residential addictions treatment facility (Study 2), and discharged civil psychiatric patients (Study 3). The primary aim of the studies was to examine the cannabis-IPV association while accounting for problematic alcohol use and psychopathic personality traits. Using bootstrap procedures, the studies examined the independent association of cannabis with perpetration of physical assault and psychological aggression, accounting for problematic alcohol use and psychopathic personality. In general, across three studies, the results do not support a direct association between cannabis and perpetration of aggression against an intimate partner. Across all three studies, frequency of cannabis use was not related to perpetration of intimate partner violence. In Study 1, cannabis evinced a trend to be associated with perpetration of IPV; however this association was accounted by both problematic alcohol use and by psychopathic personality traits. In Study 2 and Study 3, cannabis demonstrated no univariate association or even a trend with perpetration of IPV, and no association when accounting for alcohol use and psychopathy, and spurious effects could not be investigated. Overall, the findings suggest potential partial support for the existence of a spurious-effects conceptualization of the relationship between cannabis and perpetration of IPV, and suggest further research is required to characterize the relationship in a variety of populations.

description: This paper deals with iteration stable (STIT) tessellations, and, more generally, with a certain class of tessellations that are infinitely divisible with respect to iteration. They form a new, rich and flexible class of spatio-temporal models considered in stochastic geometry. The martingale tools developed in \cite{STP1} are used to study second-order properties of STIT tessellations. Firstly, a general formula for the variance of the total surface area of cell boundaries inside a convex observation window is shown. This general expression is combined with tools from integral geometry to derive explicit exact and asymptotic second-order formulae in the stationary and isotropic set-up, where a family of chord-power integrals plays an important role. Also a general formula for the pair-correlation function of the surface measure is found.

description: Maternal health, the topic of the CWP Forum on which this report is based, is a vital concern for all societies around the world. The wellbeing of pregnant women and mothers, and the care they receive before, during, and after delivery, is integral to the health of every mother and child, and to the families and communities to which they belong. Yet while significant progress has been made in improving maternal health over the last several decades, in recent years the rate of progress in a number of countries has slowed considerably or even regressed. Meanwhile, gaps in access to high quality maternal health care – not only between regions and countries, but also within countries – are growing.

On January 29, 2019, CWP invited approximately 35 experts from inside and outside of Columbia University who represent a range of substantive and institutional perspectives, to deepen our understanding of why it has proven so challenging to achieve global health targets for maternal health, discuss the root causes of the problem, and identify ways in which we might substantially improve maternal health outcomes. Out of nearly 20 ideas proposed and described in this report, three will now be developed further by CWP as potential projects, based on the recommendations of experts at the Forum. Many of the remaining proposals will be pursued through other channels and as they are, CWP will work to foster their development and track their impact.

description: (1) Background: The prognosis of cancer is dependent on immune cells in the tumor microenvironment (TME). The protein S100A9 is an essential regulator of the TME, associated with poor prognosis. In this study, we evaluated early therapy effects on the TME in syngeneic murine breast cancer via S100A9-specific in vivo imaging. (2) Methods: Murine 4T1 cells were implanted orthotopically in female BALB/c mice (n = 59). Tumor size-adapted fluorescence imaging was performed before and 5 days after chemo- (Doxorubicin, n = 20), anti-angiogenic therapy (Bevacizumab, n = 20), or placebo (NaCl, n = 19). Imaging results were validated ex vivo (immunohistochemistry, flow cytometry). (3) Results: While tumor growth revealed no differences (p = 0.48), fluorescence intensities (FI) for S100A9 in Bevacizumab-treated tumors were significantly lower as compared to Doxorubicin (2.60 vs. 15.65 AU, p < 0.0001). FI for Doxorubicin were significantly higher compared to placebo (8.95 AU, p = 0.01). Flow cytometry revealed shifts in monocytic and T-cell cell infiltrates under therapy, correlating with imaging. (4) Conclusions: S100A9-specific imaging enables early detection of therapy effects visualizing immune cell activity in the TME, even before clinically detectable changes in tumor size. Therefore, it may serve as a non-invasive imaging biomarker for early therapy effects.

description: Within the variational approach of Bose liquids we analyze the g.s. energy of charge neutral alpha matter at $T$=0. As a prerequisite for such calculation we take from the literature or propose new $\alp-\alp$ potentials that are particularly suitable for this task, i.e. posses a repulsive core and/or reproduce the low energy scattering data and the resonance properties of the $\alp-\alp$ system. The alpha matter EOS is then obtained with the HNC method using Pandharipande-Bethe correlation derived variationally in the lowest order expansion of the energy functional or a simple gaussian function with a healing range determined by the normalization of the radial distribution function in the lowest order. We show that saturation is achieved only via repulsive and shallow potentials that are not consistent with the scattering and resonance constraints.

Kink oscillations of flowing threads in solar prominences

description: Recent observations by Hinode/SOT show that MHD waves and mass flows are simultaneously present in the fine structure of solar prominences. We investigate standing kink magnetohydrodynamic (MHD) waves in flowing prominence threads from a theoretical point of view. We model a prominence fine structure as a cylindrical magnetic tube embedded in the solar corona with its ends line-tied in the photosphere. The magnetic cylinder is composed of a region with dense prominence plasma, which is flowing along the magnetic tube, whereas the rest of the flux tube is occupied by coronal plasma. We use the WKB approximation to obtain analytical expressions for the period and the amplitude of the fundamental mode as functions of the flow velocity. In addition, we solve the full problem numerically by means of time-dependent simulations. We find that both the period and the amplitude of the standing MHD waves vary in time as the prominence thread flows along the magnetic structure. The fundamental kink mode is a good description for the time-dependent evolution of the oscillations, and the analytical expressions in the WKB approximation are in agreement with the full numerical results. The presence of flow modifies the period of the oscillations with respect to the static case. However, for realistic flow velocities this effect might fall within the error bars of the observations. The variation of the amplitude due to the flow leads to apparent damping or amplification of the oscillations, which could modify the real rate of attenuation caused by an additional damping mechanism.

description: We report on a novel non-invasive method to determine the normal mode frequencies of ion Coulomb crystals in traps based on the resonance enhanced collective coupling between the electronic states of the ions and an optical cavity field at the single photon level. Excitations of the normal modes are observed through a Doppler broadening of the resonance. An excellent agreement with the predictions of a zero-temperature uniformly charged liquid plasma model is found. The technique opens up for investigations of the heating and damping of cold plasma modes, as well as the coupling between them.

description: We conclude our analysis of bubble divergences in the flat spinfoam model. In [arXiv:1008.1476] we showed that the divergence degree of an arbitrary two-complex Gamma can be evaluated exactly by means of twisted cohomology. Here, we specialize this result to the case where Gamma is the two-skeleton of the cell decomposition of a pseudomanifold, and sharpen it with a careful analysis of the cellular and topological structures involved. Moreover, we explain in detail how this approach reproduces all the previous powercounting results for the Boulatov-Ooguri (colored) tensor models, and sheds light on algebraic-topological aspects of Gurau's 1/N expansion.

description: We present a method, based on the positive weight next-to-leading-order matching formalism (POWHEG), to simulate photon production processes at next-to-leading-order (NLO). This technique is applied to the simulation of diphoton production in hadron-hadron collisions. The algorithm consistently combines the parton shower and NLO calculation, producing only positive weight events. The simulation includes both the photon fragmentation contribution and a full implementation of the truncated shower required to correctly describe soft emissions in an angular-ordered parton shower.
