description: The number and the location of the monopoles observed on the lattice in QCD configurations happens to depend strongly on the choice of the gauge used to expose them, in contrast to the physical expectation that monopoles be gauge invariant objects. It is proved by use of the non abelian Bianchi identities (NABI) that monopoles are indeed gauge invariant, but the method used to detect them depends, in a controllable way, on the choice of the abelian projection. Numerical checks are presented.

description: We have developed high dispersion VPH (volume phase holographic) grisms with zinc selenide (ZnSe) prisms for the cryogenic optical system of MOIRCS (Multi-Object near InfraRed Camera and Spectrograph) for Y-, J-, H- and K- band observations. We fabricated the VPH gratings using a hologram resin. After several heat cycles at between room temperature and 120 K, the VPH gratings were assembled to grisms by gluing with two ZnSe prisms. Several heat cycles were also carried out for the grisms before being installed into MOIRCS. We measured the efficiencies of the VPH grisms in a laboratory, and found them to be 70% - 82%. The performances obtained by observations of MOIRCS with the 8.2 m Subaru Telescope have been found to be very consistent with the results in the laboratory test. This is the first astronomical application of cryogenic VPH grisms.

description: We discuss the large-x behaviour of the splitting functions P_qg and P_gq and of flavour-singlet coefficient functions, such as the gluon contributions C_2,g and C_L,g to the structure functions F_2,L, in massless perturbative QCD. These quantities are suppressed by one or two powers of 1-x with respect to the 1/(1-x) terms which are the subject of the well-known threshold exponentiation. We show that the double-logarithmic contributions to P_qg, P_gq and C_L at order alpha_s^4 can be predicted from known third-order results and present, as a first step towards a full all-order generalization, the leading-logarithmic large-x behaviour of P_qg, P_gq and C_2,g at all orders in alpha_s.

description: We experimentally demonstrate a non-local generation of entanglement from two independent photonic sources in an ancilla-free process . Two bosons (photons) are entangled in polarization space by steering into a novel interferometer setup, in which they have never meet each other. The entangled photons are delivered to polarization analyzers in different sites, respectively, and a non-local interaction is observed. Entanglement is further verified by the way of the measured violation of a CHSH type Bell's inequality with S-values of 2.54 and 27 standard deviations. Our results will shine a new light into the understanding on how quantum mechanics works, have possible philosophic consequences on the one hand and provide an essential element for quantum information processing on the other hand. Potential applications of our results are briefly discussed.

description: Faint Object Camera and Spectrograph (FOCAS) is a versatile common-use optical instrument for the 8.2m Subaru Telescope, offering imaging and spectroscopic observations. FOCAS employs grisms with resolving powers ranging from 280 to 8200 as dispersive optical elements. A grism is a direct-vision grating composed of a transmission grating and prism(s). FOCAS has five grisms with replica surface-relief gratings including an echelle-type grism, and eight grisms with volume-phase holographic (VPH) gratings. The size of these grisms is 110 mm X 106 mm in aperture with a maximum thickness of 110 mm. We employ not only the dichromated gelatin, but also the hologram resin as a recording material for VPH gratings. We discuss the performance of these FOCAS grisms measured in the laboratory, and verify it by test observations, and show examples of astronomical spectroscopic observations.

description: A series of new 2,4-bis[(substituted-aminomethyl)phenyl]quinoline, 1,3-bis[(substituted-aminomethyl)phenyl]isoquinoline, and 2,4-bis[(substituted-aminomethyl)phenyl]quinazoline derivatives was designed, synthesised, and evaluated in vitro against three protozoan parasites (Plasmodium falciparum, Leishmania donovani, and Trypanosoma brucei brucei). Biological results showed antiprotozoal activity with IC50 values in the µM range. In addition, the in vitro cytotoxicity of these original molecules was assessed with human HepG2 cells. The quinoline 1c was identified as the most potent antimalarial candidate with a ratio of cytotoxic to antiparasitic activities of 97 against the P. falciparum CQ-sensitive strain 3D7. The quinazoline 3h was also identified as the most potent trypanosomal candidate with a selectivity index (SI) of 43 on T. brucei brucei strain. Moreover, as the telomeres of the parasites P. falciparum and Trypanosoma are possible targets of this kind of nitrogen heterocyclic compounds, we have also investigated stabilisation of the Plasmodium and Trypanosoma telomeric G-quadruplexes by our best compounds through FRET melting assays.

description: Gradual disruption of the actin cytoskeleton induces a series of structural shape changes in cells leading to a transformation of cylindrical cell extensions into a periodic chain of "pearls". Quantitative measurements of the pearling instability give a square-root behavior for the wavelength as a function of drug concentration. We present a theory that explains these observations in terms of the interplay between rigidity of the submembranous actin shell and tension that is induced by boundary conditions set by adhesion points. The theory allows estimation of the rigidity and thickness of this supporting shell. The same theoretical considerations explain the shape of nonadherent edges in the general case of untreated cells.

The Loss Rank Criterion for Variable Selection in Linear Regression Analysis

Subjects: subject: Methodology (stat.ME)

description: Lasso and other regularization procedures are attractive methods for variable selection, subject to a proper choice of shrinkage parameter. Given a set of potential subsets produced by a regularization algorithm, a consistent model selection criterion is proposed to select the best one among this preselected set. The approach leads to a fast and efficient procedure for variable selection, especially in high-dimensional settings. Model selection consistency of the suggested criterion is proven when the number of covariates d is fixed. Simulation studies suggest that the criterion still enjoys model selection consistency when d is much larger than the sample size. The simulations also show that our approach for variable selection works surprisingly well in comparison with existing competitors. The method is also applied to a real data set.

An exploration of middle-aged and older gay men's health and illness practices
Creators: name: Handlovsky, Ingrid Emilia
Publisher: name: University of British Columbia
Year: 2018

description: Background: Despite a wealth of knowledge that demonstrates middle-aged and older gay men experience substantial health inequities when compared to heterosexual men, little information is available pertaining to the health and illness practices of gay men. Methods: This dissertation includes three qualitative manuscripts with the overarching aim of exploring middle-aged and older gay men’s health and illness practices. Data were collected via conversational interviews with 25 men who self-identified as gay. The first qualitative descriptive manuscript examined how middle-aged and older gay men developed resilience over time to promote health and wellness. Next, a grounded theory was conducted to describe the processes by which middle-aged and older gay men managed their health. The third manuscript involved a qualitative description of how men experienced their mental health and the strategies they used to mitigate the deleterious effects of mental health challenges. Results: The findings from the first manuscript demonstrated that resilience was developed over time by: (1) building and sustaining networks, (2) addressing mental health, and (3) advocating for self. The grounded theory indicated that the core process of health management is overcoming adversity, which is achieved by three overarching and interrelated processes: (1) advocating for health needs, (2) knowing about health issues and treatments, and 3) engaging in health promoting practices. The third manuscript findings yielded three categories as to how mental health was experienced, and how the deleterious effects of mental health challenges were mitigated: (1) gaining new perspectives of mental health over time, (2) reaching out to formal health services for support with mental health challenges, and (3) engaging in practices to maintain and improve psychological well-being. Conclusion: These findings highlight the influence of age and experience, historical and ongoing discrimination, as well as capacity, to middle-aged and older gay men’s health and illness practices. Consequently, meaningful and effective health services must be developed with recognition of men’s strengths and capacities amidst discrimination. Potential approaches to health service development and delivery to improve health outcomes include equity-oriented primary health care, trauma-informed care, social public health approaches and peer-based services and resources.

description: Recent progress in the fabrication of atomically precise quantum wires and quantum dots by cleaved edge overgrowth is reviewed. This technique is based on molecular beam epitaxy along two or three directions in space and is capable of producing low-dimensional structures in which all relevant sizes are controlled on an atomic scale. Different sample structures consisting of isolated quantum dots as well as of linear arrays of coupled quantum dots are studied by micro photoluminescence spectroscopy. Optical emission from zero-dimensional states in these dots is characterized by extremely narrow linewidths of less than 70 eV. Resonant excitation of one of the dot levels in coupled systems leads to emission from all the other levels. As a result of the quantum mechanical coupling of the almost identical dots anti-Stokes luminescence, i.e. thermally activated transfer of oscillator strength from one dot to another, whose emission is slightly higher in energy, is observed.

description: The approximation of the renormalized stress-energy tensor of the quantized massive scalar field in Reissner-Nordström spacetime is constructed. It is achieved by functional differentiation of the first two nonvanishing terms of the Schwinger-DeWitt expansion involving the coincidence limit of the Hadamard-Minakshisundaram-DeWitt-Seely coefficients $[a_{3}]$ and $[a_{4}]$ with respect to the metric tensor. It is shown, by comparison with the existing numerical results, that inclusion of the second-order term leads to substantial improvement of the approximation of the exact stress-energy tensor. The approximation to the field fluctuation, $\langle ϕ^{2} \rangle,$ is constructed and briefly discussed.

description: The differential scanning fluorimetry (DSF) screening of 5.692 fragments in combination with benzenesulfonamide (BSA) against bovine carbonic anhydrase (bCA) delivered >100 hits that either caused, on their own, a significant thermal shift (ΔTm , °C) in the protein melting temperature or significantly influenced the thermal shift observed for BSA alone. Three hits based on 1,2,3-triazole moiety represent the periphery of the recently reported potent inhibitors of hCA II, IX and XII which were efficacious in vivo. Such a re-discovery of suitable BSA periphery essentially validates the new fragment-based approach to the discovery of future CAIs. Structures of other validated fragment hits are reported.

description: Cluster N is a region of the visual forebrain of nocturnally migrating songbirds that supports the geomagnetic compass of nocturnal migrants. Cluster N expresses immediate-early genes (ZENK), indicating neuronal activation. This neuronal activity has only been recorded at night during the migratory season. Night-to-night variation in Cluster N activity in relation to migratory behaviour has not been previously examined. We tested whether Cluster N is activated only when birds are motivated to migrate and presumably engage their magnetic compass. We measured immediate-early gene activation in Cluster N of white-throated sparrows (Zonotrichia albicollis) in three conditions: daytime, nighttime migratory restless, and nighttime resting. Birds in the nighttime migratory restlessness group had significantly greater numbers of ZENK-labelled cells in Cluster N compared to both the daytime and the nighttime resting groups. Additionally, the degree of migratory restlessness was positively correlated with the number of ZENK-labelled cells in the nighttime migratory restless group. Our study adds to the number of species observed to have neural activation in Cluster N and demonstrates for the first time that immediate early gene activation in Cluster N is correlated with the amount of active migratory behaviour displayed across sampled individuals. We conclude that Cluster N is facultatively regulated by the motivation to migrate, together with nocturnal activity, rather than obligatorily active during the migration season.

description: Bioisosteric replacement and scaffold hopping are powerful strategies in drug design useful for rationally modifying a hit compound towards novel lead therapeutic agents. Recently, we reported a series of thienopyrimidinones that compromise dynamics at the p66/p51 HIV-1 reverse transcriptase (RT)-associated Ribonuclease H (RNase H) dimer interface, thereby allosterically interrupting catalysis by altering the active site geometry. Although they exhibited good submicromolar activity, the isosteric replacement of the thiophene ring, a potential toxicophore, is warranted. Thus, in this article, the most active 2-(3,4-dihydroxyphenyl)-5,6-dimethylthieno[2,3-d]pyrimidin-4(3H)-one 1 was selected as the hit scaffold and several isosteric substitutions of the thiophene ring were performed. A novel series of highly active RNase H allosteric quinazolinone inhibitors was thus obtained. To determine their target selectivity, they were tested against RT-associated RNA-dependent DNA polymerase (RDDP) and integrase (IN). Interestingly, none of the compounds were particularly active on (RDDP) but many displayed micromolar to submicromolar activity against IN.

description: In this paper, we consider approximability issues of the following four problems: triangle packing, full sibling reconstruction, maximum profit coverage and 2-coverage. All of them are generalized or specialized versions of set-cover and have applications in biology ranging from full-sibling reconstructions in wild populations to biomolecular clusterings; however, as this paper shows, their approximability properties differ considerably. Our inapproximability constant for the triangle packing problem improves upon the previous results; this is done by directly transforming the inapproximability gap of Haastad for the problem of maximizing the number of satisfied equations for a set of equations over GF(2) and is interesting in its own right. Our approximability results on the full siblings reconstruction problems answers questions originally posed by Berger-Wolf et al. and our results on the maximum profit coverage problem provides almost matching upper and lower bounds on the approximation ratio, answering a question posed by Hassin and Or.

description: A series of bio-organometallic-hydrazones of the general formula [{(η5-C5H4)-C(R)=N–N(H)-C6H4-4-SO2NH2}]MLn(MLn = Re(CO)3, Mn(CO)3, FeCp; R=H, CH3) were prepared by reaction of formyl/acetyl organometallic precursors with 4-hydrazino-benzenesulphonamide. All compounds were characterized by conventional spectroscopic techniques (infra-red, 1H and 13C NMR, mass spectrometry and elemental analysis). Biological evaluation as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors agents was carried out using four human/h) isoforms, hCA I, II, IX and XII. The cytosolic isoforms hCA I and II were effectively inhibited by almost all derivatives with inhibition constants of 1.7–22.4 nM. Similar effects were observed for the tumour-associated transmembrane isoform hCA XII (KIs of 1.9–24.4 nM). hCA IX was less sensitive to inhibition with these compounds. The presence of bio-organometallic or metallo-carbonyl moieties in the molecules of these CAIs makes them amenable for interesting pharmacologic applications, for example for compounds with CO donating properties.

description: The present study explores electronic and structural properties, ionization potential (IP), electron affinity (EA), polarizability (α), chemical potential (μ), hardness (η), softness (S), band gap (ΔE(HOMO-LUMO)) and spectral characteristics of beryllium hydride oligomers by quantum chemical treatment. The discrepancies in the calculated reactive descriptors of molecules are presumably due to variations in electron distribution and spin pairing near Fermi level. The molecules BeH2, Be3H5, Be5H10, Be7H14 and Be9H18 have been found to be more stable than Be2H4, Be4H8, Be6H12, Be8H16 and Be10H20. Ultra-soft pseudopotentials for electron-nuclei interactions with local density approximation (LDA) and generalized gradient approximation (GGA) have been used to understand the nature of bonding in crystalline beryllium hydride. The observed band gap value of crystalline BeH2 is comparable with the band gap value of beryllium hydride oligomers

description: The mass-loss rate of donor stars in cataclysmic variables (CVs) is of paramount importance in the evolution of short-period CVs. Observed donors are oversized in comparison with those of isolated single stars of the same mass, which is thought to be a consequence of the mass loss. Using the empirical mass-radius relation of CVs and the homologous approximation for changes in effective temperature T_2, orbital period P, and luminosity of the donor with the stellar radius, we find the semi-empirical mass-loss rate M2_dot of CVs as a function of P. The derived M2_dot is at ~10^(-9.5)-10^(-10) Msun/yr and depends weakly on P when P > 90 min, while it declines very rapidly towards the minimum period when P < 90 min, emulating the P-T_2 relation. Due to strong deviation from thermal equilibrium caused by the mass loss, the semi-empirical M2_dot is significantly different from, and has a less-pronounced turnaround behavior with P than suggested by previous numerical models. The semi-empirical P-M2_dot relation is consistent with the angular momentum loss due to gravitational wave emission, and strongly suggests that CV secondaries with 0.075 Msun < M_2 < 0.2 Msun are less than 2 Gyrs old. When applied to selected eclipsing CVs, our semi-empirical mass-loss rates are in good agreement with the accretion rates derived from the effective temperatures T_1 of white dwarfs, suggesting that M2_dot can be used to reliably infer T_2 from T_1. Based on the semi-empirical M2_dot, SDSS 1501 and 1433 systems that were previously identified as post-bounce CVs have yet to reach the minimal period.

description: The Sun is an enigmatic star that produces the most powerful explosive events in our solar system – solar flares and coronal mass ejections. Studying these phenomena can provide a unique opportunity to develop a deeper understanding of fundamental processes on the Sun, and critically, to better forecast space weather. The Active Region Classification and Flare Forecasting (ARCAFF) project will develop a beyond state-of-the-art flare forecasting system utilising end-to-end deep learning (DL) models to significantly improve upon traditional flare forecasting capabilities.

The large amount of available space-based solar observations are an ideal candidate for this type of analysis, given DL effectiveness in modelling complex relationships. DL has already been successfully developed and deployed in weather forecasting, financial services, and health care domains but has not been fully exploited in the solar physics domain. ARCAFF will increase the accuracy and timeliness of current operational flare forecast products and create new time series flare forecasts with uncertainties. The forecasts will be benchmarked against current systems using international community standards. The datasets and codes developed for ARCAFF will be made openly available to support further research efforts and encourage their re-use.

This presentation will provide a short overview of the project and present early results from the two ARCAFF topics,

The fractal spatial distribution of stars in open clusters and stellar associations

description: The Interstellar Medium has a fractal structure, in the sense that gas and dust distribute in a hierarchical and self-similar manner. Stars in new-born cluster probably follow the same fractal patterns of their parent molecular clouds. Moreover, it seems that older clusters tend to distribute their stars with radial density profiles. Thus, it is expected that clusters form with an initial fractal distribution of stars that eventually evolves toward centrally concentrated distributions. Is this really the case? This simple picture on to the origin and early evolution of star clusters and associations is very far from being clearly understood. There can be both young clusters exhibiting radial patterns and evolved clusters showing fractal structure. Additionally, the fractal structure of some open clusters is very different from that of the Interstellar Medium in the Milky Way. Here we summarize and discuss observational and numerical evidences concerning this subject.

Emerging scholars' socialization into scholarly publication : negotiating identities and investments in a neoliberal era
Creators: name: Fazel, Ismaeil
Publisher: name: University of British Columbia
Year: 2018

description: Given the paramount importance of publication in academia, socialization of novice scholars into scholarly publication has received increasing scholarly attention. Extant empirical literature has tended to predominantly focus on impediments facing English as an Additional Language (EAL) doctoral students (e.g., Ho, 2017; Li, 2007; Lillis & Curry, 2010) in getting published, although recent research has also attended to issues encountered by Anglophone doctoral students in academic publication (Habibie, 2016). However, there is a paucity of longitudinal research that compares the publication processes and practices of EAL and Anglophone doctoral students. Moreover, little research thus far has compared the perspectives and practices of novices vis-à-vis established scholars in writing for publication. In this 16-month, multiple-case study on four - two Anglophone and two EAL - doctoral students in language education at a Canadian university, questionnaires, multiple semi-structured interviews, submission trajectories, and communications with journal editors and reviewers were used as the chief sources of data. Additionally, 27 editors and editorial boards members of well-known journals in applied linguistics and language education were interviewed to triangulate their perspectives with the experiences of the doctoral students in the study. The data were subject to iterative thematic analysis, and interpreted in light of the theoretical constructs of academic discourse socialization (Duff, 2010), and identity and investment (Darvin & Norton, 2015). Findings indicate that learning how to academically write a paper - i.e., discursive and generic dimensions of writing for publication (e.g., Habibie, 2016; Huang, 2010; Li, 2007) - is arguably important yet not sufficient in getting published. Perhaps more importantly, the findings suggest that navigating today's increasingly digitized terrain of academic publication demands socialization into a set of strategic competencies and tactical sensibilities, including the sensibility of knowing where (and where not) to publish and learning how to navigate and negotiate the process of academic publishing and its inherent complexities.

description: The dual phosphatases CDC25 are involved in cell cycle regulation and overexpressed in many tumours, including melanoma. CDC25 is a promising target for discovering anticancer drugs, and several studies focussed on characterisation of quinonoid CDC25 inhibitors, frequently causing undesired side toxic effects. Previous work described an optimisation of the inhibition properties by naphthylphenylamine (NPA) derivatives of NSC28620, a nonquinonoid CDC25 inhibitor. Now, the CDC25B•inhibitor interaction was investigated through fluorescence studies, shedding light on the different inhibition mechanism exerted by NPA derivatives. Among the molecular processes, mediating the specific and high cytotoxicity of one NPA derivative in melanoma cells, we observed decrease of phosphoAkt, increase of p53, reduction of CDC25 forms, cytochrome c cytosolic translocation and increase of caspase activity, that lead to the activation of an apoptotic programme. A basic knowledge on CDC25 inhibitors is relevant for discovering potent bioactive molecules, to be used as anticancer agents against the highly aggressive melanoma.
title: Rethinking public engagement in the development approvals process

Subjects: subject: City planning--Citizen participation

description: In a report published by the Provincial Government in 2019 public hearings were identified to be hindering the success of the development approvals process. However, public participation is not the issue, it is the systems in place that render it ineffective. Public participation should still be considered an essential part of development planning as it allows opportunities for the public to have a say in how their cities are built. This research aims to identify alternative and supplemental options to improve the public hearing process to better engage the public, while minimizing additional delays or costs. Results from interviews with local government planners and a literature review concluded that public hearings are flawed, but planners want to see them improved upon rather than removed all together. Nine recommendations, along with an Engagement Framework are presented as a deliverable for local government planners to implement improved public engagement.
The synthesis and optimization of functionalized hyperbranched polyglycerols as potential topical hemostatic agents
Creators: name: Liu, Chu
Publisher: name: University of British Columbia
Year: 2018

description: As a classical representative of the hyperbranched polymer family, hyperbranched polyglycerol has been applied in a variety of diagnostics and therapies. After functionalizing the end groups with zwitterionic sulfabetaines (SB) and cationic quaternary amines (QA), the polymer exhibited superior hemagglutination capacity at a concentration ≥ 1 mg/mL and erythrocyte lysis was not observed. The goal in the present work is to use the monomers above to maximize the polymer adhesion to cells while eliminating the membrane damage caused by multivalent polycation exposure. The desired stickiest structure is a novel attractive bioadhesive material which may serve as a future topical hemostatic agent for bleeding wounds, overcoming the limitations of existing products in the market. To this end an optimization was performed on the synthesis scheme to achieve a library of HPG based polymer conjugates with a constant amount of one derivative (SB/QA) and a varied number of the other derivative (QA/SB). The efficacy of sulfabetaine (SB) and quaternary amine (QA) was quantified and different hemagglutination behaviors were displayed. Hemolysis, cytotoxicity and inhibition effects as well as the hydration properties of the polymer conjugates were also evaluated. In the blood aggregation analysis, HPG-SB₃₀-QA₃₀-OH₄₀ and HPG-SB₃₀-QA₄₀-OH₃₀ exhibited strong red blood cells aggregation effects even at a concentration as low as 1mg/mL. Thirty percent of SB also reduced the hemolytic activity to an undetectable level and retained high cell viability in the presence of 30% QA. The bound water of each repeat monomer unit was quantified by differential scanning calorimetry and explained the fouling resistance behavior of the cells. The addition of linear polyglycerol sulfate into the HPG-SB-QA-OH system effectively suppressed the red blood cell aggregation, which indicated the possibility of reversibly applying the materials for hemostasis. Overall, the in vitro studies suggest that the stickiest structure of the designed functionalized HPG is HPG-SB₃₀-QA₃₀-OH₄₀, which is biocompatible and harmless to cells.
