Functionalizing carbon nanotubes as a model to study the actin-based mechanism used by baculovirus to enter the cell nucleus
Creators: name: Sadr Karimi, Shaghayegh
Publisher: name: University of British Columbia
Year: 2019

description: The cell nucleus is protected by an impermeable nuclear envelope (NE) containing nuclear pore complexes (NPCs), through which controlled trafficking of molecules between the cytoplasm and the nucleus occurs. Baculovirus nucleocapsids, which are rod-shaped DNA containing capsids, have the ability to cross the NPC to deliver their genome into the nucleus. However, baculovirus nucleocapsids do not have signaling motifs required for conventional signal mediated nuclear import. Furthermore, they are considered to be too large for passive diffusion through the NPC. Recently, our laboratory has proposed that baculovirus nucleocapsids use an unconventional strategy to enter the nucleus via actin propulsion. A Wiskott-Aldrich syndrome protein (WASP)-like protein on one end of the baculovirus nucleocapsid hijacks the actin polymerization machinery of the host cell to promote the formation of actin comet tails that propel the nucleocapsid through the NPC. The main aim of this thesis is to test whether multiwalled carbon nanotubes (MWCNTs), which like baculovirus nucleocapsids are rod-shaped, can enter the nucleus using actin-based propulsion. I have accomplished this by functionalizing MWCNTs, enabling them to induce actin polymerization, similar to baculovirus nucleocapsids. MWCNTs with baculovirus nucleocapsid-like diameters were conjugated to WASP. Successful protein conjugation to MWCNTs was confirmed using immuno-gold electron microscopy. Similar levels of MWCNT-WASP and our corresponding control complex, MWCNT-BSA-Cy3, were present inside HeLa cells; however, their ability to enter the nuclei was significantly different. Nuclear MWCNT-WASP was detected in more than half the cell population. In contrast, MWCNT-BSA-Cy3 was detected in only a few nuclei. Successful nuclear entry of MWCNT-WASP was also detected in semi-permeabilized cells. Moreover, disrupting actin polymerization noticeably decreased nuclear entry of MWCNT-WASP. Furthermore, isolated nuclei were incubated with MWCNT-WASP and G-actin under iii conditions of actin polymerization. Following this, confocal imaging depicted physical depressions of the NE at the sites where MWCNT-WASPs were docked. Taken together, these results indicate that mechanical force generated by actin-based propulsion can drive the nuclear entry of MWCNT-WASP. This supports the conclusion that the baculovirus nucleocapsid uses actin-based propulsion to enter the nucleus through the NPC.

description: Leishmaniasis is a neglected disease caused by the protozoa Leishmania ssp. Environmental differences found by the parasites in the vector and the host are translated into cellular stress, leading to the production of heat shock proteins (Hsp). These are molecular chaperones involved in the folding of nascent proteins as well as in the regulation of gene expression, signalling events and proteostasis. Since Leishmania spp. use Hsp90 to trigger important transitions between their different stages of the life cycle, this protein family becomes a profitable target in anti-parasite drug discovery. In this work, we implemented a multidisciplinary strategy coupling molecular modelling with in vitro assays to identify small molecules able to inhibit Hsp90 from L. braziliensis (LbHsp90). Overall, we identified some compounds able to kill the promastigote form of the L. braziliensis, and to inhibit LbHsp90 ATPase activity.

description: The education system in Canada has represented institutional injustice and oppression for Indigenous people since the government set up the Residential School System in the 1880’s. In the wake of the report released by the Truth and Reconciliation Commission (TRC) in 2015, the concept of cultural safety has become a major component of the institutional justice and oppression conversation when considering K to 12 education in Canadian provinces and territories. While not a new approach to education, Culturally Responsive Schooling and Education (CRS/E) is one approach that has been employed over the years to improve the educational outcomes of Indigenous youth in Canada, the US, and Australia by creating culturally safe spaces. This project offered an opportunity to explore the experiences of Indigenous alumni who attended a CRS during the 1980’s and 1990’s. The participants reflected on both their negative experiences and memories of attending mainstream schools, and the positive impact the CRS/E had on them 30 to 40 years after they graduated. The study findings support the results from research conducted around the world on the impact of racism, and CRS/E systems on Indigenous learners.

description: We analyze the exact formulae for the resistance between two arbitrary notes in a rectangular network of resistors under free, periodic and cylindrical boundary conditions obtained by Wu [J. Phys. A 37, 6653 (2004)]. Based on such expression, we then apply the algorithm of Ivashkevich, Izmailian and Hu [J. Phys. A 35, 5543 (2002)] to derive the exact asymptotic expansions of the resistance between two maximum separated nodes on an $M \times N$ rectangular network of resistors with resistors $r$ and $s$ in the two spatial directions. Our results is $ \frac{1}{s}R_{M\times N}(r,s)= c(ρ)\, \ln{S}+c_0(ρ,ξ)+\sum_{p=1}^{\infty} \frac{c_{2p}(ρ,ξ)}{S^{p}} $ with $S=M N$, $ρ=r/s$ and $ξ=M/N$. The all coefficients in this expansion are expressed through analytical functions. We have introduced the effective aspect ratio $ξ_{eff} = \sqrtρ\;ξ$ for free and periodic boundary conditions and $ξ_{eff} = \sqrtρ\;ξ/2$ for cylindrical boundary condition and show that all finite size correction terms are invariant under transformation $ξ_{eff} \to {1}/ξ_{eff}$.

On the Shannon Cipher System With a Wiretapper Guessing Subject to Distortion and Reliability Requirements

Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences
subject: 94A05

description: In this paper we discuss the processes in the Shannon cipher system with discrete memoryless source and a guessing wiretapper. The wiretapper observes a cryptogram of $N$-vector of ciphered messages in the public channel and tries to guess successively the vector of messages within given distortion level $Δ$ and small probability of error less than $\exp \{-NE\}$ with positive reliability index $E$. The security of the system is measured by the expected number of guesses which wiretapper needs for the approximate reconstruction of the vector of source messages. The distortion, the reliability criteria and the possibility of upper limiting the number of guesses extend the approach studied by Merhav and Arikan. A single-letter characterization is given for the region of pairs $(R_L,R)$ (of the rate $R_L$ of the maximum number of guesses $L(N)$ and the rate $R$ of the average number of guesses) in dependence on key rate $R_K$, distortion level $Δ$ and reliability $E$.

Understanding the Loss of The Commons
Creators: name: Houser, Neil Owen
Publisher: name: Critical Education
Year: 2023

description: The decline of public education and the concomitant loss of the commons are increasingly recognized as significant and interwoven issues. Like other prevailing societal problems, such as the tenacity of institutionalized racism, classism, and patriarchy, these conditions are rooted in the ways growing numbers of people have come to think and act – socially, economically, politically, and intellectually. In a word, they are structural problems. As such, they require educators and others concerned with the health of society and well-being of the planet to address not only the observable symptoms but also the underlying factors that have spawned and perpetuated the systems in the first place. Critical scholars generally understand that problematic structural conditions are produced and maintained by prevailing systems of thought and action, that they evolve within particular social and historical contexts, and that they have often been instituted through oppressive mechanisms of persuasion and control. Less understood are the ways these intersecting systems, contexts, and mechanisms are perpetuated via largely “invisible” perceptual and temporal factors that obscure the processes at play. Understanding the relationships between these various factors is essential to effectively addressing the challenges we face. This paper synthesizes the literature in critical theory, ecological philosophy and living systems theories, Indigenous studies, and the sociology of knowledge to examine these intersecting factors and to consider implications for theory and practice in education.

Real-time applications of synchrophasor-based wide-area measurement systems
Creators: name: Rahmatian, Matin
Publisher: name: University of British Columbia
Year: 2018

description: In this thesis, we focus on two major real-time applications of modern synchrophasor-based wide-area measurement systems , i.e., transient stability assessment (TSA) and fault detection and identification (FDI). First, we develop a tool for real-time TSA based on automatic learning approaches. We use Classification and Regression Tree (CART) as the classification tool and Multivariate Adaptive Regression Splines (MARS) as the regression tool. To train and validate these tools in a practical setting, we conduct test cases on the full Western Electricity Coordinated Council system model, with emphasis on the BC Hydro (BCH) power system. While being mindful of practical field implementations of the proposed methods, our studies assume limited number of phasor measurement units (PMUs) installed, in accordance with existing infrastructure in the BCH system. The trained CART models are tested and show high accuracy rates, and thus, will be able to predict the transient stability issues of the system under study following different contingencies using the synchrophasors obtained from limited number of PMUs in the system. Also, the MARS models, which are proposed to be applied for TSA for the first time, show reasonable prediction accuracy rates. Next, we investigate the possibility of an accurate real-time FDI using synchrophasors received from PMUs installed at the two ends of a transmission line. We apply a new metric called goodness-of- fit (GoF), which is calculated over the time span of measurement and can quantify the credibility of the received synchrophasors. Then, we apply the data to an FDI method to show how accurate and credible the results are. The obtained results show a reasonable relation between the GoF metric, i.e., credibility of the measured sychrophasors, and the accuracy of the obtained results, validating the significance of the proposed method for real-time applications. As it is very rare to have a real power system with all buses and transmission lines equipped with PMUs, we also propose a wide-area real-time FDI approach using a linear observer. Through this wide-area approach, we demonstrate the effectiveness of the proposed method by accurately locating a fault in a small test system.

description: The main purpose of this paper is to show that OADP varieties stand at an important crossroad of various main streets in different disciplines like projective geometry, birational geometry and algebra. This is a good reason for studying and classifying them. Main specific results are: (a) the classification of all OADP surfaces (regardless to their smoothness); (b) the classification of a relevant class of normal OADP varieties of any dimension, which includes interesting examples like lagrangian grassmannians. Following [PR], the equivalence of the classification in (b) with the one of quadro-quadric Cremona transformations and of complex, unitary, cubic Jordan algebras are explained.

description: A general formulation of phase-field models for nonisothermal solidification in multicomponent and multiphase alloy systems is derived from an entropy functional in a thermodynamically consistent way. General expressions for the free energy densities, for multicomponent diffusion coefficients, and for both weak and faceted types of surface energy and kinetic anisotropy are possible. A three-dimensional simulator is developed to show the capability of the model to describe phase transitions, complex microstructure formation, and grain growth in polycrystalline textures.

description: Twisted assemblies of filaments in ropes, cables and bundles are essential structural elements in wide use in macroscopic materials as well as within the cells and tissues of living organisms. We develop the unique, non-linear elastic properties of twisted filament bundles that derive from generic properties of two-dimensional line-ordered materials. Continuum elasticity reveals a formal equivalence between the elastic stresses induced by bundle twist and those induced by the positive curvature in thin, elastic sheets. These geometrically-induced stresses can be screened by 5-fold disclination defects in lattice packing, and we predict a discrete spectrum elastic energy groundstates associated with integer numbers of disclinations in cylindrical bundles. Finally, we show that elastic-energy groundstates are extremely sensitive to defect position in the cross-section, with off-center disclinations driving the entire bundle to buckle, adopting globally writhing configurations.

Polar foliations and isoparametric maps

description: A singular Riemannian foliation $F$ on a complete Riemannian manifold $M$ is called a polar foliation if, for each regular point $p$, there is an immersed submanifold $Σ$, called section, that passes through $p$ and that meets all the leaves and always perpendicularly. A typical example of a polar foliation is the partition of $M$ into the orbits of a polar action, i.e., an isometric action with sections. In this work we prove that the leaves of $F$ coincide with the level sets of a smooth map $H: M\to Σ$ if $M$ is simply connected. In particular, we have that the orbits of a polar action on a simply connected space are level sets of an isoparametric map. This result extends previous results due to the author and Gorodski, Heintze, Liu and Olmos, Carter and West, and Terng.

description: We extend the Carlstrom and Fuerst (American Economic Review, 1997, 87, pp. 893–910) agency cost model of business cycles by including time-varying uncertainty in the technology shocks that affect capital production. We first demonstrate that standard linearization methods can be used to solve the model yet second moments enter the economy’s equilibrium policy functions.We then demonstrate that an increase in uncertainty causes, ceteris paribus, a fall in investment supply. We also show that persistence of uncertainty affects both quantitatively and qualitatively the behaviour of the economy.

description: A form of normalisation is presented for the evaluation of citation data on multidisciplinary research. This method is based on the existing classification according to the publishing journals and not on the classification of output according to ISI subject categories. A publication profile is created for each institution to be investigated. This profile accounts for the weight of publications in a journal, represented by the number of publications as a proportion of the total output of the institution. In accordance with this weight, the citation rate of each journal is compared to a qualified relative indicator. The final result is a relative citation rate J, which is the relative perception of the performance of an institution accounting for its publication and citation habits and makes a transdisciplinary comparison possible.

description: We report the first spectroscopic study using a low temperature near-field scanning optical microscope. We have studied an array of GaAs/AlGaAs cleaved edge overgrowth quantum wires. The three luminescence peaks originate from different structures in the sample: The (001)-oriented multiple quantum wells, the (110)-oriented single quantum well, and the quantum wires. The linewidth of the quantum wire emission is related to roughness in the (110)-oriented single quantum well. Quenching of the multiple quantum wells and single quantum well emission near the quantum wires is attributed to diffusion of photoexcited carriers into the wires.

description: We propose an entanglement mean field theory inspired approach for dealing with interacting classical many-body systems. It involves a coarse-graining technique that terminates a step before the mean field theory: While mean field theory deals with only single-body physical parameters, the entanglement mean field theory deals with single- as well as two-body ones. We improve the theory to a cluster entanglement mean field, that deals with a fundamental unit of the lattice of the many-body system. We apply these methods to interacting Ising spin systems in several lattice geometries and dimensions, and show that the predictions of the onset of criticality of these models are much better in the proposed theories as compared to the corresponding ones in mean field theories.

description: Long-duration gamma-ray bursts (GRBs) provide a premier tool for studying high-redshift star-forming galaxies thanks to their extreme brightness and association with massive stars. Here we use GRBs to study the galaxy stellar mass-metallicity (M*-Z) relation at z~3-5, where conventional direct metallicity measurements are extremely challenging. We use the ISM metallicities of LGRB hosts derived from afterglow absorption spectroscopy (Z~0.01-1 solar), in conjunction with host galaxy stellar masses determined from deep Spitzer 3.6 micron observations of 20 GRB hosts. We detect about 1/4 of the hosts with I-band magnitudes ~ -21.5 to -22.5 AB mag, and place a limit of M > -19 mag on the remaining hosts from a stacking analysis. Using these observations, we present the first rest-frame optical luminosity distribution of long GRB hosts at z>3 and find that it is similar to the distribution of long GRB hosts at z~1. In comparison to Lyman-break galaxies at the same redshift, GRB hosts are generally fainter, but the sample is too small to rule out an overall similar luminosity function. On the other hand, the GRB hosts appear to be more luminous than the population of Lyman-alpha emitters at z~3-4. Using a conservative range of mass-to-light ratios for simple stellar populations (with ages of 70 Myr to ~2 Gyr), we infer the host stellar masses and present mass-metallicity measurements at z~3-5 ( ~ 3.5). We find that the detected GRB hosts, with M*~2e10 solar masses, display a wide range of metallicities, but that the mean metallicity at this mass scale, Z~0.1 solar, is lower than measurements at z<3. Combined with stacking of the non-detected hosts with M*< 3e9 solar masses and Z<0.03 solar, we find evidence for the existence of an M*-Z relation at z~3.5 and continued evolution of this relation to systematically lower metallicities from z~2.

title: One-dimensional chiral topological insulators in ladder models
Creators: name: Hewitt, Tyler

description: The topological insulator state describes a quantum state of matter that hosts topologically protected conductive edge modes, similar to the quantum spin Hall state but without the necessary applied fields. The coupling of topology to condensed matter theory in the context of topological insulators has produced the periodic table of topological insulators and superconductors. The ever popular SSH chain has become the prototypical model for describing simple topological properties in one-dimension. It is widely known that this model, in its modern form, hosts symmetry protected end states that are at zero energy. This model has supported mountains of research. In this thesis we will use two deformed SSH model chains to constuct ladder models that are topological insulators in each of the chiral universality classes (AIII, BDI, CII, DIII, and CI). We systematically construct these models from general forms to specific forms examining their energy and wavefunction spectrums, leading easily to the conclusion of their topological nature. These constructions are motivated by the finding that the winding number has a sign ambiguity. This ambiguity leads to two forms of the chiral symmetry operator and subsequently two forms of the ladder, one adhering to the BDI and CII universality classes, and one for the DIII and CI classes. We are able to analytical derive expressions for the edge states in each chiral class ladder model and demonstrate the symmetry properties of each are encoded in these states. Additionally we show that, as a consequence of the sign ambiguity, for a weak interchain coupling, the winding numbers of the individual chains can be added leading to an index of 2, in the case of the BDI and CII class models, or subtracted giving an index of 0 in the case of the DIII and CI models. The conclusions and properties from this section of work is completely general and applicable to other chiral models. In the final section of research we show via diagrammatic arguments and mean field theory the existence of a Z2 symmetry breaking bond density wave ground state in an SSH-like model with density-density interactions and a reduced filling fraction. The reduced filling fraction stabilizes a topological ground state where interactions would normally not permit one to exist. We further demonstrate this ground state occurs as a result of mean field rather than strong correlation effects. The ground state model turns out to be the noninteracting SSH4 model which we show has quantized Zak phases of individual bands confirming the topological nature of the model in a reduced filling fraction regime.

description: В статье освещаются принципы применения нейролингвистического подхода при изучении структурных особенностей и смыслового кода фразеологических единиц латинского языка с их дальнейшей интерпретацией в русском языке. Эта методика раскрывает механизмы восприятия устойчивых сочетаний любого языка и позволяет перекодировать смысл фразеологизма в языке перевода с учетом особенностей менталитета его носителя. Процесс переключения языковых кодов осуществляется на основе подбора эквивалентных смыслов устойчивых сочетаний. Суть проблемы состоит в том, что, фразеологизмы, возникшие на основе метафоризации, представляют собой маргинальную часть языкового кода, а их смысл не равен сумме смыслов всех компонентов. Данная методика освоения фразеологизмов при изучении иностранного языка уже неоднократно доказала свою эффективность. Она опирается на основные принципы нейропсихолингвистики и демонстрирует особенности применения нейролингвистического подхода к изучению иностранного языка. Эта методика помогает опытным путем найти принципы переключения языковых кодов на основе подбора эквивалентных смыслов устойчивых сочетаний, при невозможности суммировать значения отдельных элементов конструкции. При этом у учащихся формируются и совершенствуются такие общие мыслительные приемы, как анализ, синтез, дифференциация и классификация номинативных единиц разных языков, а также формируется положительная учебная мотивация. Также углубляются знания по истории родного языка и совершенствуются навыки сопоставительного историко-этимологического анализа устойчивых сочетаний.

description: В статье рассматривается актуальная проблема - подготовка воспитанников организации для детей-сирот и детей, оставшихся без попечения родителей, к социальному существованию. Для выявления коммуникативных дефектов и способов их преодоления применяется неклассическая методология. Авторы опираются на интенциональную модель сознания и диалога как средства выявления и коррекции девиаций. Воспитанники учреждений интернатного типа в силу обстоятельств погружены в социум, в котором социальные связи и опыт взаимодействий максимально ограничены и клишированы. Порождаемая этими условиями социальная депривация становится дополнительным осложняющим фактором для формирования социальноадаптивных способностей детей-сирот. В информационном обществе единственным источником опыта взаимодействий в «большом» социуме и материалом для осмысления экзистенциальных проблем становится медийная среда, являющаяся носителем лиминального дискурса. Испробованным методом корректировки мировоззрения и поведения является психодрама. Использование ролевых игр в контексте театральных миниатюр позволяет решать проблему социально-ценностной корректировки сознания и поведения детей. Принципиально новым является учет авторами характера современного дискурсивного контекста - лиминального дискурса.

description: Проблема ограничения прав и свобод стала особенно актуальной в условиях распространения новой коронавирусной инфекции. Отдельным случаем таких ограничений является ограничение прав потребителей туристических услуг по сравнению с порядком, существовавшим до введения «коронавирусных» норм. В частности, в ряде случаев при расторжении договора туристы смогут получить внесенные ими денежные средства лишь по истечении полутора лет после запланированной поездки. В связи с этим представляется необходимым исследовать законность и обоснованность подобных ограничений, их соответствие международным нормам. В статье проанализированы ограничения прав потребителей туристических услуг, на основании чего сделаны предложения по совершенствованию принятых норм и вывод о необходимости ограничений прав в связи с тем, что одновременное обращение в суд значительного числа потребителей приведет к невозможности защиты нарушенных прав потребителей вследствие банкротств предпринимателей и недостаточности их средств для выплат всем потребителям.

description: Осмотр места происшествия по делам о пожарах - это первоочередное, не терпящее отлагательства и незаменимое следственное действие, предоставляющее возможность непосредственного восприятия обстановки места пожара. Обнаружение следов на месте пожара требует высокой квалификации лиц, принимающих участие в данном следственном действии, использования специальных знаний. Надлежащая подготовка к этому следственному действию, обеспечение полноты и объективности осмотра, грамотная фиксация материальной обстановки, следов термического воздействия, а также преступных действий создает предпосылки для проведения качественной работы на месте происшествия и расследования преступления. В статье на основе изучения судебно-следственной практики рассматриваются криминалистические рекомендации по фиксации следовой картины места пожара в протоколе следственного осмотра, отмечены наиболее часто допускаемые следователями и специалистами ошибки и процессуальные нарушения при производстве этого следственного действия.

description: This paper presents a micromechanical study of unsaturated granular media in the pendular regime, based upon numerical experiments using the discrete element method, compared to a microstructural elastoplastic model. Water effects are taken into account by adding capillary menisci at contacts and their consequences in terms of force and water volume are studied. Simulations of triaxial compression tests are used to investigate both macro and micro-effects of a partial saturation. The results provided by the two methods appear to be in good agreement, reproducing the major trends of a partially saturated granular assembly, such as the increase in the shear strength and the hardening with suction. Moreover, a capillary stress tensor is exhibited from capillary forces by using homogenisation techniques. Both macroscopic and microscopic considerations emphasize an induced anisotropy of the capillary stress tensor in relation with the pore fluid distribution inside the material. In so far as the tensorial nature of this fluid fabric implies shear effects on the solid phase associated with suction, a comparison has been made with the standard equivalent pore pressure assumption. It is shown that water effects induce microstrural phenomena that cannot be considered at the macro level, particularly when dealing with material history. Thus, the study points out that unsaturated soil stress definitions should include, besides the macroscopic stresses such as the total stress, the microscopic interparticle stresses such as the ones resulting from capillary forces, in order to interpret more precisely the implications of the pore fluid on the mechanical behaviour of granular materials.

description: PT-symmetric systems can have a real spectrum even when their Hamiltonian is non-hermitian, but develop a complex spectrum when the degree of non-hermiticity increases. Here we utilize random-matrix theory to show that this spontaneous PT-symmetry breaking can occur via two distinct mechanisms, whose predominance is associated to different universality classes. Present optical experiments fall into the orthogonal class, where symmetry-induced level crossings render the characteristic absorption rate independent of the coupling strength between the symmetry-related parts of the system.

description: We consider the contributions of the extra gauge boson Z' to the like sign $τ$ production process $e^-γ\to e^+(μ^+)τ^-τ^-$, induced by the tree-level flavor changing interactions. Since these rare production are far below the observable level in the Standard Model and other popular new physics models such as the minimal supersymmetric model, we find that Z' can give significant contributions to this process, and with reasonable values of the parameters in TC2 models, the cross section can reach several tens of fb and may be detected at the $eγ$ collisions.
