description: Background and purpose: Glioblastoma (GBM) patients face a strongly unfavorable prognosis despite multimodal therapy regimens. However, individualized mortality prediction remains imprecise. Harnessing routine radiation planning cranial computed tomography (CT) scans, we assessed cervical body composition measures as novel biomarkers for overall survival (OS) in GBM patients. Materials and methods: We performed threshold-based semi-automated quantification of muscle and subcutaneous fat cross-sectional area (CSA) at the levels of the first and second cervical vertebral body. First, we tested this method’s validity by correlating cervical measures to established abdominal body composition in an open-source whole-body CT cohort. We then identified consecutive patients undergoing radiation planning for recent GBM diagnosis at our institution from 2010 to 2020 and quantified cervical body composition on radiation planning CT scans. Finally, we performed univariable and multivariable time-to-event analyses, adjusting for age, sex, body mass index, comorbidities, performance status, extent of surgical resection, extent of tumor at diagnosis, and MGMT methylation. Results: Cervical body composition measurements were well-correlated with established abdominal markers (Spearman’s rho greater than 0.68 in all cases). Subsequently, we included 324 GBM patients in our study cohort (median age 63 years, 60.8% male). 293 (90.4%) patients died during follow-up. Median survival time was 13 months. Patients with below-average muscle CSA or above-average fat CSA demonstrated shorter survival. In multivariable analyses, continuous cervical muscle measurements remained independently associated with OS. Conclusion: This exploratory study establishes novel cervical body composition measures routinely available on cranial radiation planning CT scans and confirms their association with OS in patients diagnosed with GBM.

Cultura e ideias do liberalismo

description: A emergência do liberalismo enquanto regime político pode considerar-se o ponto culminante de um longo processo cultural, marcado pela complexidade decorrente em grande parte da diversidade de facetas que o caracterizam. Sendo a ideia de liberdade a ideia fulcral, entendida no sentido de ser livre como no de libertação, implicava simultaneamente a situação do indivíduo e da sociedade face ao poder. Implicava igualmente a reflexão do modelo aristotélicas veiculado pela Igreja Católica e comummente aceite e a sua substituição pelo modelo jus-naturalista e, consequentemente, a substituição da mundivivência teológica laica no entendimento do homem, do mundo e da vida. E significava por fim a valorização da temporalidade como o tempo próprio do ser e da vida humana e, daí do lugar onde ambos se projectam. O presente texto pretende apresentar traços as incidências destas mutações, desde o momento de ruptura representado pelos teóricos da Escola Alemã de Direito Natural até ao contributo de Krauser e seus discípulos.

description: We analyze a single-channel seismic (SCS) reflection profile that completely crosses the zone of deformed oceanic lithosphere in the central Indian Ocean at 78.8” E. By summing the apparent shortening on all seismically resolvable faults (throws > ~ 10 m), we find that 11.2 + 2 km of shortening has occurred at this longitude during the past 7.5 m.y. This estimate, together with the 27 ± 5 km of shortening previously estimated from a multichannel seismic (MCS) profile farther east at 81.5° E, are consistent with the west-to-east increase in shortening predicted by Euler poles which treat the Indian and Australian plates as separate tectonic units. Our result therefore provides direct evidence from the deformation itself that the compression of oceanic lithosphere in the central Indian Ocean, originally regarded as ‘intraplate’, is better described as constituting part of a broad boundary zone between distinct Indian and Australian plates. We also examine the size statistics of faults revealed in SCS and MCS profiles running nearly normal to the deformation trends in the longitude band 78.8°E - 81.5°E. The N-S extent of the deformation does not change appreciably over these longitudes. We find that the average fault spacing remains constant at about 7 km, whereas the mean throw increases systematically from west to east (~ 74 m to ~ 177 m). Basically the contribution of ‘small’ faults (those with throws of l0 - 50 m) decreases systematically across the deforming region (i.e., with increasing amount of shortening). This suggests that the deformation occurs by reactivation of a select fault population, that these faults continue to add displacement with time and that relatively few new faults are initiated. We also infer from the fault size statistics that the contribution to the deformation of faults below the resolution of the seismic methods (~ 10 m for SCS and ~ 50 m for MCS) is likely to be quite limited.
The molecular evolution of floral colour shifts in Lathyrus L. (Fabaceae)
Creators: name: Xue, Xinxin
Publisher: name: University of British Columbia
Year: 2016

description: In this thesis, I used Lathyrus to study floral colour evolution. My work builds on that of pioneer geneticists who used the sweet pea (Lathyrus odoratus) for research in early 20th century England. They used the rich horticultural resource of inbred cultivars for genetic study. More recently, studies on flavonoid biochemistry and the phylogenetics of Lathyrus lend tools to place the colour shifts in an evolutionary and molecular context. In chapter 2, I show that the A1 locus is a missense mutation (332 G/A) in the substrate recognition site (SRS1) of flavonoid 3’,5’-hydroxylase (F3’5’H) and is associated with the pink mutant cultivar ‘Painted Lady’ (‘PL’). This single base pair substitution in the mutant F3’5’H is speculated to toggle the enzyme from primary F3’5’H activity to a relatively efficient F3’H, as shown in a heterologous transformation in Arabidopsis PAP1D (a mutant line that produces anthocyanin constitutively). In chapter 3, I constructed a multi-species coalescent tree using Bayesian inference and reconstructed the ancestral states for floral colour, life history trait (perennial or annual) and floral pattern. The ancestral states for Lathyrus are anthocyanin rich (AR), annual and concolourous. However, no correlation was found between the life history trait (which is linked to breeding systems) and the loss of anthocyanin colour in the petal, when corrected for phylogenetic independence. This suggests that in Lathyrus, autogamous species are as colourful as allogamous ones even though the latter are expected to need greater floral display. In chapter 4, I found that the lack of expression in dihydroflavonol reductase (DFR) was associated with a white mutant cultivar ‘Mrs Collier’ (‘MC’) of L. odoratus via a trans-regulatory machinery. Two transcription factors, the sweet pea orthologues of AN2 (MYB) and AN1 (bHLH) were also not expressed although neither was associated with the white phenotype in an F2-cosegregation analysis. This DFR silencing was also observed in another white mutant of the domesticated grass pea (L. sativus). In contrast, when unpigmented wild species originate under natural selection, DFR expression, if at all affected, is lowered rather than fully silenced, likely due to pleiotropic effects.

description: Data-driven newsvendor methods offer promising solutions for estimating replenishment quantity within complex markets by leveraging demand-related features. However, most features utilized by these methods rely on manual selection, and some important unobservable features cannot be thoroughly utilized. These issues might result in the loss of some crucial information, thus incurring considerable cost in these decision-making results, meaning that there is still much room for improvement. To remedy this, we propose a time series imaging-based deep learning method, which automatically extracts crucial features alongside those selected manually. This method maximizes the advantages of time series imaging, convolutional neural networks, bidirectional long short-term memory networks, and multilayer perceptron networks. Experiments with four diverse product time series and real-world data show that our approach reduces the average newsvendor problem cost by 16.33% to 33.43% compared to the best benchmark, highlighting its robustness. Additionally, each component within our method significantly contributes to decision-making.

description: Along-axis gradients in mantle Bouguer anomalies (MBAs) were calculated for detailed gravity surveys at the Southwest, Central, and Southeast Indian ridges with half-spreading rates of 0.9, 2.3, and 3.1 cm/yr, respectively. MBA gradients at the very slow spreading Southwest Indian Ridge are 0.4–0.7 mGal/km, similar to the gradients found at the slow-spreading Mid-Atlantic Ridge, whereas gradients at the Central Indian and Southeast Indian ridges are 0.2– 0.35 mGal/km. The results of this study, when combined with other published data, show that axial MBA gradients at ridge segments with an axial high are about 0.1 mGal/km, independent of spreading rate. Gradients at segments with a median valley are higher and generally decrease with increasing spreading rate. The spreading-rate–independent MBA gradient at ridge segments with an axial high represents the mantle gravity signal due to the focusing of upwelling within segments. The larger gravity gradients at segments with an axial valley result from the superposition of intra-segment variations in crustal thickness on this mantle signal. The consistent relation between along-axis MBA gradient and across-axis axial morphology suggests that the axial morphology is related to the efficiency of along-axis transport of melt.
The Shanghai Manhua Society : a history of early Chinese cartoonists, 1918-1938
Creators: name: Stember, Nick
Publisher: name: University of British Columbia
Year: 2016

description: Towards the end of the 19th century, the first illustrated pictorials began to appear in China. Satirical cartoons found their way into Chinese newspapers and magazines over the following decades, as print technology gradually improved. By the 1910s illustrated pictorials began to proliferate, along with the first examples of humor magazines, a trend which would continue through the 1920s. By the early 1930s, China had over two dozen magazines dedicated to satirical comics, or manhua, as they came to be known. This study looks at the Manhua Society, a group of semi-professional cartoonists whose members were active in Shanghai from roughly 1918 to 1938. By pooling their resources and working under a common banner, the Manhua Society members were not only able to find employment, but also to step into the role of publishers themselves, financed by day jobs in advertising and education. This study reconstructs the history of the society using oral histories, academic studies, and primary source materials (translating many previously unavailable in English). It focuses on eight key members of the Manhua Society: Ye Qianyu, Ji Xiaobo, Ding Song, Zhang Guangyu, Lu Shaofei, Wang Dunqing, Huang Wennong, and Hu Xuguang. These men saw their careers transformed by a series of escalating military conflicts: the May 4 Movement of 1919, the Zhili-Anhui War of 1920, the first Zhili-Fengtian War of 1922, the Jiangsu-Zhejiang War and second Zhili-Fengtian War of 1924, the May 30 Movement of 1925, the Northern Expedition of 1926-1928, including the Shanghai Massacre of 1927, and the first Japanese invasions of Shanghai in 1932 and 1937. Their stories show how the history of Chinese comics was shaped by individuals, as well as organizations. Although this industry was crippled by the Japanese invasion of Shanghai in 1937, the same cartoonists would go on to work in the propaganda offices of World War II, the Chinese Civil War, and the Cold War. In tracing the origins of the Manhua Society, therefore, I argue that it influenced not only the development of cartooning and comics in the Republican era, but also the visual culture of the PRC.

description: Cyanophycin (multi-l-arginyl-poly-l-aspartic acid; also known as cyanophycin grana peptide [CGP]) is a biopolymer that could be used in various fields, for example, as a potential precursor for the synthesis of polyaspartic acid or for the production of CGP-derived dipeptides. To extend the applications of this polymer, it is therefore of interest to synthesize CGP with different compositions. A recent re-evaluation of the CGP synthesis in 'C. glutamicum' has shown that 'C. glutamicum' is a potentially interesting microorganism for CGP synthesis with a high content of alternative amino acids. This study shows that the amount of alternative amino acids can be increased by using mutants of 'C. glutamicum' with altered amino acid biosynthesis. With the DM1729 mutant, the lysine content in the polymer could be increased up to 33.5 mol%. Furthermore, an ornithine content of up to 12.6 mol% was achieved with ORN2(Pgdh4). How much water-soluble or insoluble CGP is synthesized is strongly related to the used cyanophycin synthetase. CphADh synthesizes soluble CGP exclusively. However, soluble CGP could also be isolated from cells expressing CphA6308Δ1 or CphA6308Δ1_C595S in addition to insoluble CGP in all examined strains. The point mutation in CphA6308Δ1_C595S partially resulted in a higher lysine content. In addition, the CGP content could be increased to 36% of the cell dry weight under optimizing growth conditions in 'C. glutamicum' ATCC13032. All known alternative major amino acids for CGP synthesis (lysine, ornithine, citrulline, and glutamic acid) could be incorporated into CGP in 'C. glutamicum'.

description: Event-by-event fluctuations of initial QCD-matter density produced in heavy-ion collisions at RHIC enhance the production of thermal photons significantly in the region $2 \le p_T \le 4$ GeV/$c$ compared to a smooth initial-state averaged profile in the ideal hydrodynamic calculation. This enhancement is a an early time effect due to the presence of hotspots or over-dense regions in the fluctuating initial state. The effect of fluctuations is found to be stronger in peripheral than in central collisions.

description: Energy consumption and delay incurred in packet delivery are the two important metrics for measuring the performance of geographic routing protocols for Wireless Adhoc and Sensor Networks (WASN). A protocol capable of ensuring both lesser energy consumption and experiencing lesser delay in packet delivery is thus suitable for networks which are delay sensitive and energy hungry at the same time. Thus a smart packet forwarding technique addressing both the issues is thus the one looked for by any geographic routing protocol. In the present paper we have proposed a Fermat point based forwarding technique which reduces the delay experienced during packet delivery as well as the energy consumed for transmission and reception of data packets.

Although it has generally been thought that they are accelerated in the shock waves associated with powerful supernova explosions-for which there have been recent claims of evidence-the mystery is far from resolved. In fact, we may be on the wrong track altogether in looking for isolated regions of cosmic-ray acceleration.

description: Chromatin bridges connecting the two segregating daughter nuclei arise from chromosome fusion or unresolved interchromosomal linkage. Persistent chromatin bridges are trapped in the cleavage plane, triggering cytokinesis delay. The trapped bridges occasionally break during cytokinesis, inducing DNA damage and chromosomal rearrangements. Recently, Caenorhabditis elegans LEM-3 and human TREX1 nucleases have been shown to process chromatin bridges. Here, it is shown that ANKLE1 endonuclease, the human ortholog of LEM-3, accumulates at the bulge-like structure of the midbody via its N-terminal ankyrin repeats. Importantly, ANKLE1-/- knockout cells display an elevated level of G1-specific 53BP1 nuclear bodies, prolonged activation of the DNA damage response, and replication stress. Increased DNA damage observed in ANKLE1-/- cells is rescued by inhibiting actin polymerization or reducing actomyosin contractility. ANKLE1 does not act in conjunction with structure-selective endonucleases, GEN1 and MUS81 in resolving recombination intermediates. Instead, ANKLE1 acts on chromatin bridges by priming TREX1 nucleolytic activity and cleaving bridge DNA to prevent the formation of micronuclei and cytosolic dsDNA that activate the cGAS-STING pathway. It is therefore proposed that ANKLE1 prevents DNA damage and autoimmunity by cleaving chromatin bridges to avoid catastrophic breakage mediated by actomyosin contractile forces.

description: A recent Hydrosweep survey of the Wilkes transform system, the second-fastest-slipping transform on the mid-ocean ridge system, shows it to be a highly complex and continually evolving plate boundary. An area ~50 km2 north of the eastern part of the Wilkes transform appears to be rotating counterclockwise in accordance with the theory of edge-driven microplate kinematics. We have called this region a "nannoplate" to distinguish it both as a separate small area of lithosphere between the Pacific and Nazca plates and as a smaller and less stable phenomenon than a microplate.

This is done from first principles using a two-particle Hamiltonian for both an harmonic oscillator and Coulomb binding potential. In the high frequency limit, the response function falls off as 1/ω^2 whilst at low frequencies it tends to a constant value.

description: The muon detection system of the Compact Muon Solenoid experiment at the CERN Large Hadron Collider is based on different technologies for muon tracking and triggering. In particular, the muon system in the endcap disks of the detector consists of Resistive Plate Chambers for triggering and Cathode Strip Chambers for tracking. At present, the endcap muon system is only partially instrumented with the very forward detector region remaining uncovered. In view of a possible future extension of the muon endcap system, we report on a feasibility study on the use of Micro-Pattern Gas Detectors, in particular Gas Electron Multipliers, for both muon triggering and tracking. Results on the construction and characterization of small tripleGas Electron Multiplier prototype detectors are presented.

description: We introduce a regularized anisotropic modified Cam-clay (MCC) model which captures the size-dependent anisotropic elastoplastic responses for clay, mudstone, shales, and sedimentary rock. By homogenizing the multiscale anisotropic effects induced by clay particle aggregate, clusters, peds, micro-fabric, and mineral contact across length scales, we introduce two distinctive anisotropic mechanisms for the MCC model at the material point and mesoscale levels. We first employ a mapping that links the anisotropic stress state to a fictitious isotropic principal stress-space to introduce anisotropy at the material point scale. Then, the mesoscale anisotropy is introduced via an anisotropic regularization mechanism. This anisotropic regularization mechanism is triggered by introducing gradient-dependence of the internal variables through a penalty method such that the resultant gradient-enhanced plastic flow may exhibit anisotropic responses non-coaxial to the stress gradient of the yield function.

Plastid genome evolution in partially and fully mycoheterotrophic eudicots
Creators: name: Darby, Hayley
Publisher: name: University of British Columbia
Year: 2016

description: Plastid-genome evolution following photosynthesis loss is characterized by substantial change, contrasting with strong conservation in most photosynthetic land plants. Common features of reduced plastid genomes across diverse heterotrophic lineages point to a predictable trajectory of genome degradation, but this has been only partly tested. Here I document the molecular evolution of plastid genomes belonging to several mycoheterotroph lineages in Ericaceae, Gentianaceae and Polygalaceae, which include several independent origins of mycoheterotrophy in eudicot angiosperms that span different time scales since photosynthesis loss. I used next-generation and Sanger sequencing techniques to assemble complete plastomes or gene sets for comparative analyses of gene content and genome structure, and phylogenomic inference. I also sequenced several partially mycoheterotrophic and fully autotrophic relatives. Patterns of gene loss in mycoheterotroph plastomes are generally consistent with a previously hypothesized trajectory of change, starting with the loss of plastid NAD(P)H dehydrogenase before full loss of photosynthesis, and ending (here) with substantial reduction in genes involved in the translation apparatus and other nonphotosynthetic functions. Several retentions (delayed losses) of subunit genes for plastid-encoded polymerase, plastid ATP synthase and Rubisco are also consistent with hypothesized secondary (nonphotosynthetic) functions for these complexes. Two within-genus comparisons (for Epirixanthes in Polygalaceae and Voyria in Gentianaceae) demonstrate substantially different levels of genome degradation, consistent with heterogeneity in rates of genome change after a given origin of full mycoheterotrophy. Mycoheterotrophs in two families (Ericaceae, Polygalaceae) have extensive genome rearrangement compared to most land plants, contrasting with near colinearity in mycoheterotrophic members of Gentianaceae (despite sometimes extensive genome reduction in the latter). However, these contrasting patterns are apparently not associated with transitions to mycoheterotrophy, as photosynthetic relatives in Ericaceae and Polygalaceae are also substantially rearranged—or with inverted repeat loss (evident in Epirixanthes pallida, Polygalaceae), as autotrophic Polygala retains its inverted repeats. Phylogenomic inferences of core eudicot phylogeny made using the retained genes are generally well supported and robust to a variety of phylogenetic approaches, and are also congruent with recent phylogenetic studies in each mycoheterotrophic family.

description: Motivated by the Golub–Heath–Wahba formula for ridge regression, we first present a new leave-one-out lemma for the kernel support vector machines (SVM) and related large-margin classifiers. We then use the lemma to design a novel and efficient algorithm, named “magicsvm,” for training the kernel SVM and related large-margin classifiers and computing the exact leave-one-out cross-validation error. By “magicsvm,” the computational cost of leave-one-out analysis is of the same order of fitting a single SVM on the training data. We show that “magicsvm” is much faster than the state-of-the-art SVM solvers based on extensive simulations and benchmark examples. The same idea is also used to boost the computation speed of the V-fold cross-validation of the kernel classifiers.

description: We use the variational method for the Sturm-Liouville eigenvalue problem to analytically calculate some properties of holographic superconductors with Gauss-Bonnet gravity in probe limit. By studying the holographic p-wave and s-wave superconductors in (3+1)-dimensional boundary field theories, it is found that near the critical temperature, the critical exponent of the condensation is 1/2 which is the universal value in mean-field theory. We also find that when Gauss-Bonnet coefficients grow bigger the operators on the boundary field theory will be harder to condense. These are in good agreement with the numerical results.

description: We propose a finite elements algorithm to solve a fourth order partial differential equation governing the propagation of time-harmonic bending waves in thin elastic plates. Specially designed perfectly matched layers are implemented to deal with the infinite extent of the plates. These are deduced from a geometric transform in the biharmonic equation. To numerically illustrate the power of elastodynamic transformations, we analyse the elastic response of an elliptic invisibility cloak surrounding a clamped obstacle in the presence of a cylindrical excitation i.e. a concentrated point force. Elliptic cloaking for flexural waves involves a density and an orthotropic Young's modulus which depend on the radial and azimuthal positions, as deduced from a coordinates transformation for circular cloaks in the spirit of Pendry et al. [Science {\bf 312}, 1780 (2006)], but with a further stretch of a coordinate axis. We find that a wave radiated by a concentrated point force located a couple of wavelengths away from the cloak is almost unperturbed in magnitude and in phase. However, when the point force lies within the coating, it seems to radiate from a shifted location. Finally, we emphasize the versatility of transformation elastodynamics with the design of an elliptic cloak which rotates the polarization of a flexural wave within its core.

description: Detailed bathymetric data from a Hydrosweep multibeam sonar survey of a 250 km-long portion of the 'superfast'- spreading southern East Pacific Rise crest and flanks show that the along-axis variation in morphology and axial depth differs significantly from that observed at the fast-spreading northern East Pacific Rise. While the deep mantle upwelling pattern is similar under the northern and southern East Pacific Rise, our observations require that the connectivity of the shallow, subcrestal plumbing system be more efficient beneath the 'super-fast' spreading southern East Pacific Rise than beneath the slower spreading northern East Pacific Rise.

On multidimensional analogs of Melvin's solution for classical series of Lie algebras

description: A multidimensional generalization of Melvin's solution for an arbitrary simple Lie algebra $\cal G$ is presented. The gravitational model contains n 2-forms and $l \geq n$ scalar fields, wheren is the rank of $\cal G$. The solution is governed by a set of n functions obeying n ordinary differential equations with certain boundary conditions. It was conjectured earlier that these functions should be polynomials (the so-called fluxbrane polynomials). A program (in Maple) for calculating of these polynomials for classical series of Lie algebras is suggested (see Appendix). The polynomials corresponding to the Lie algebra D_4 are obtained. It is conjectured that the polynomials for A_n-, B_n- and C_n-series may be obtained from polynomials for D_{n+1}-series by using certain reduction formulas.

description: The inner silicon detector of the Compact Muon Solenoid experiment (CMS) at CERN's LHC consists of 16588 modules. Charged-particle tracks in the detector are used to improve the accuracy to which the position and orientation of the modules is known. This contribution focuses on the Millepede-II algorithm, one of the two alignment algorithms used by CMS. Recently an advanced track model has been introduced into the CMS alignment procedure, which is based on the "Broken Lines" model and is able to take multiple Coulomb scattering in the detector material properly into account. We show the unique approach needed for solving the alignment problem in a reasonable amount of time. Emphasis is given to the mathematical treatment of the problem.

description: Crystallization and vitrification of tetrahedral liquids are important both from a fundamental and a technological point of view. Here, we study via extensive umbrella sampling Monte Carlo computer simulations the nucleation barriers for a simple model for tetrahedral patchy particles in the regime where open tetrahedral crystal structures (namely cubic and hexagonal diamond and their stacking hybrids) are thermodynamically stable. We show that by changing the angular bond width, it is possible to move from a glass-forming model to a readily crystallizing model. From the shape of the barrier we infer the role of surface tension in the formation of the crystalline clusters. Studying the trends of the nucleation barriers with the temperature and the patch width, we are able to identify an optimal value of the patch size that leads to easy nucleation. Finally, we find that the nucleation barrier is the same, within our numerical precision, for both diamond crystals and for their stacking forms.

Infinitesimal Liouville currents, cross-ratios and intersection numbers

description: Many classical objects on a surface S can be interpreted as cross-ratio functions on the circle at infinity of the universal covering. This includes closed curves considered up to homotopy, metrics of negative curvature considered up to isotopy and, in the case of interest here, tangent vectors to the Teichmüller space of complex structures on S. When two cross-ratio functions are sufficiently regular, they have a geometric intersection number, which generalizes the intersection number of two closed curves. In the case of the cross-ratio functions associated to tangent vectors to the Teichmüller space, we show that two such cross-ratio functions have a well-defined geometric intersection number, and that this intersection number is equal to the Weil-Petersson scalar product of the corresponding vectors.

Migration, health, and physical activity : perspectives of skilled immigrant women
Creators: name: Lee, Donna Sau-Yung
Publisher: name: University of British Columbia

description: The Healthy Immigrant Effect refers to the phenomenon of declining health among immigrants after relocating to Western countries, including Canada (Newbold, 2006). Health can be defined in holistic terms as physical, mental and social well-being, and the role of publicly-delivered physical activity opportunities is often overlooked when considering the health of recent immigrant women. Instead of conceptualizing health as a result of individual choices, this study drew on an intersectional approach to understanding how three social determinants of health (SDH), migration, socioeconomic status, and gender, are interrelated and mutually reinforcing (Hankivsky & Christoffersen, 2008). The purpose was to better understand how these three SDH influence the health of women who recently immigrated to Canada, and how their participation in community-based physical activity may (or may not) be affected. Qualitative interviews were conducted with women who recently immigrated to Canada as skilled workers (n = 18, <5 years in Canada, 18+ years old) from a number of different countries and who resided in one community in the Metro Vancouver Area. Data were coded using ATLAS.ti and attention was paid as to how participants discussed health and physical activity in relation to migration, gender and socioeconomic status. A majority of study participants defined health as a balance of physical and mental health. For women who found difficulty securing stable employment and income, who had difficulties communicating in English, and/or who had limited social support, particularly their mental health was negatively affected due to their expectation and need to be employed in Canada. Community-based physical activity was often sought out as an avenue to promote physical and mental health, as well as to build social networks; however, participation in opportunities and such sought-after benefits were not always possible. Thus, it is recommended that providers of community-based physical activity address issues such as affordability, lack of women-only opportunities, accounting for the gap in local knowledge and language facility, and facilitating social and intercultural opportunities through physical activity.

description: The design of protocols to suppress the propagation of viral infections is an enduring enterprise, especially hindered by limited knowledge of the mechanisms through which extinction of infection propagation comes about. We here report on a mechanism causing extinction of a propagating infection due to intraspecific competition to infect susceptible hosts. Beneficial mutations allow the pathogen to increase the production of progeny, while the host cell is allowed to develop defenses against infection. When the number of susceptible cells is unlimited, a feedback runaway co-evolution between host resistance and progeny production occurs. However, physical space limits the advantage that the virus can obtain from increasing offspring numbers, thus infection clearance may result from an increase in host defenses beyond a finite threshold. Our results might be relevant to better understand propagation of viral infections in tissues with mobility constraints, and the implications that environments with different geometrical properties might have in devising control strategies.

The significance of using the Newcomb-Benford law as a test of nuclear half-life calculations

description: Half-life number sequences collected from nuclear data charts are found to obey the Newcomb-Benford law. Based on this fact, it has been suggested recently, that this law should be used to test the quality of nuclear decay models. In this paper we briefly recall how, when and why the Newcomb-Benford law can be observed in a set of numbers with a given probability distribution. We investigate the special case of nuclear half-lives, and show that the law provides no additional clue in understanding decay half-lives. Thus, it can play no significant role in testing nuclear decay theories.
