description: In the frequentist program, inferential methods with exact control on error rates are a primary focus. The standard approach, however, is to rely on asymptotic approximations, which may not be suitable. This paper presents a general framework for the construction of exact frequentist procedures based on plausibility functions. It is shown that the plausibility function-based tests and confidence regions have the desired frequentist properties in finite samples---no large-sample justification needed. An extension of the proposed method is also given for problems involving nuisance parameters. Examples demonstrate that the plausibility function-based method is both exact and efficient in a wide variety of problems.

The evolutionary origin of "black" kokanee (Oncorhynchus nerka) and their genetic and phenotypic diversity in the Anderson and Seton lakes system
Creators: name: Moreira, Amanda Leigh
Publisher: name: University of British Columbia
Year: 2014

description: In order to conserve intraspecific biodiversity, it is crucial to identify genetic and phenotypic variation among populations and to understand the evolutionary processes that drive the evolution and persistence of such variation. Oncorhynchus nerka exists as two basic life history forms: the anadromous form, sockeye salmon and the non-anadromous form, kokanee. Unique populations of “black” kokanee are found in Lake Saiko, Japan, and in Anderson Lake and Seton Lake in the southwestern interior of British Columbia. They are distinct from other populations of O. nerka in that “black” kokanee spawn between 20 to 70 meters below the surface of each lake and spawn in the winter or early spring, whereas O. nerka typically spawns in the autumn in streams or shallow lake beaches. Using mitochondrial DNA and nine microsatellite loci, I investigated the evolutionary origin of eastern and western North Pacific populations of “black” kokanee. Both data sets support the hypothesis that “black” kokanee in Anderson Lake, Seton Lake and Lake Saiko have a polyphyletic origin resulting from repeated episodes of parallel evolution. Further, using variation at nine microsatellite loci, I demonstrated that “black” kokanee in the Anderson and Seton lakes system are genetically distinct from sympatric populations of sockeye salmon in Gates and Portage creeks, and that Anderson and Seton lake “black” kokanee are modestly distinct from one another. Anderson and Seton lake “black” kokanee differ dramatically from one another in standard length at maturity, but no differences were found between the two populations in size-adjusted maximum body depth or in gill raker numbers. My results provide an example of parallel evolution in north temperate freshwater fishes as well as evidence of yet another facet of distinctive biodiversity within O. nerka that needs to be recognized and accounted for in conservation planning for the taxon.

description: We introduce a class of functions near zero on the logarithmic cover of the complex plane that have convergent expansions into generalized power series. The construction covers cases where non-integer powers of $z$ and also terms containing $\log z$ can appear. We show that under natural assumptions some important theorems from complex analysis carry over to the class of these functions. In particular it is possible to define a field of functions that generalize meromorphic functions and one can formulate an analytic Fredholm theorem in this class. We show that this modified analytic Fredholm theorem can be applied in spectral theory to prove convergent expansions of the resolvent for Bessel type operators and Laplace-Beltrami operators for manifolds that are Euclidean at infinity. These results are important in scattering theory as they are the key step to establish analyticity of the scattering matrix and the existence of generalized eigenfunctions at points in the spectrum.

Continuous mapping approach to the asymptotics of $U$- and $V$-statistics

Publisher: name: arXiv

Subjects: subject: Statistics Theory (math.ST)

description: We derive a new representation for $U$- and $V$-statistics. Using this representation, the asymptotic distribution of $U$- and $V$-statistics can be derived by a direct application of the Continuous Mapping theorem. That novel approach not only encompasses most of the results on the asymptotic distribution known in literature, but also allows for the first time a unifying treatment of non-degenerate and degenerate $U$- and $V$-statistics. Moreover, it yields a new and powerful tool to derive the asymptotic distribution of very general $U$- and $V$-statistics based on long-memory sequences. This will be exemplified by several astonishing examples. In particular, we shall present examples where weak convergence of $U$- or $V$-statistics occurs at the rate $a_n^3$ and $a_n^4$, respectively, when $a_n$ is the rate of weak convergence of the empirical process. We also introduce the notion of asymptotic (non-) degeneracy which often appears in the presence of long-memory sequences.

description: Despite targeted therapies and immunotherapies have revolutionized the treatment of cancer patients, only a limited number of patients have long-term responses. Moreover, due to differences within cancer patients in the tumor mutational burden, composition of the tumor microenvironment as well as of the peripheral immune system and microbiome, and in the development of immune escape mechanisms, there is no “one fit all” therapy. Thus, the treatment of patients must be personalized based on the specific molecular, immunologic and/or metabolic landscape of their tumor. In order to identify for each patient the best possible therapy, different approaches should be employed and combined. These include (i) the use of predictive biomarkers identified on large cohorts of patients with the same tumor type and (ii) the evaluation of the individual tumor with “omics”-based analyses as well as its ex vivo characterization for susceptibility to different therapies.

description: This paper reports an eight-stage procedure for tagging small specialised corpora with logical relations, grounded in the coding of two corpora of argumentative writing – one learner corpus, and one expert corpus. The tagset was developed out of Rhetorical Structure Theory. Tagging involved adjusting mark-up added by the RST Tool tree diagram program to produce a corpus with cocoa tags easily searchable with KWIC concordancing software. Results show disambiguation of form-function relationships in conjunction and a wide range of types of conjunctive language. Potential further applications in research and teaching are discussed.

description: We establish conceptually important properties of the operator product expansion (OPE) in the context of perturbative, Euclidean $φ^{4}$-quantum field theory. First, we demonstrate, generalizing earlier results and techniques of arXiv:1105.3375, that the 3-point OPE, $< O_{A_1} O_{A_2} O_{A_3} > = \sum_{C} \cal{C}_{A_1 A_2 A_3}^{C} $, usually interpreted only as an asymptotic short distance expansion, actually converges at finite, and even large, distances. We further show that the factorization identity $\cal{C}_{A_1 A_2 A_3}^{B}=\sum_{C}\cal{C}_{A_1 A_2}^{C} \cal{C}_{C A_3}^{B}$ is satisfied for suitable configurations of the spacetime arguments. Again, the infinite sum is shown to be convergent. Our proofs rely on explicit bounds on the remainders of these expansions, obtained using refined versions, mostly due to Kopper et al., of the renormalization group flow equation method. These bounds also establish that each OPE coefficient is a real analytic function in the spacetime arguments for non-coinciding points. Our results hold for arbitrary but finite loop orders. They lend support to proposals for a general axiomatic framework of quantum field theory, based on such `consistency conditions' and akin to vertex operator algebras, wherein the OPE is promoted to the defining structure of the theory.

The targum (1872:Apr.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1872

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Threats on the stability of a financial system may severely affect the functioning of the entire economy, and thus considerable emphasis is placed on the analyzing the cause and effect of such threats. The financial crisis in the current and past decade has shown that one important cause of instability in global markets is the so-called financial contagion, namely the spreading of instabilities or failures of individual components of the network to other, perhaps healthier, components. This leads to a natural question of whether the regulatory authorities could have predicted and perhaps mitigated the current economic crisis by effective computations of some stability measure of the banking networks. Motivated by such observations, we consider the problem of defining and evaluating stabilities of both homogeneous and heterogeneous banking networks against propagation of synchronous idiosyncratic shocks given to a subset of banks. We formalize the homogeneous banking network model of Nier et al. and its corresponding heterogeneous version, formalize the synchronous shock propagation procedures, define two appropriate stability measures and investigate the computational complexities of evaluating these measures for various network topologies and parameters of interest. Our results and proofs also shed some light on the properties of topologies and parameters of the network that may lead to higher or lower stabilities.

description: The study of the partition function in M-theory involves the use of index theory on a twelve-dimensional bounding manifold. In eleven dimensions, viewed as a boundary, this is given by secondary index invariants such as the Atiyah-Patodi-Singer eta-invariant, the Chern-Simons invariant, or the Adams e-invariant. If the eleven-dimensional manifold itself has a boundary, the resulting ten-dimensional manifold can be viewed as a codimension two corner. The partition function in this context has been studied by the author in relation to index theory for manifolds with corners, essentially on the product of two intervals. In this paper, we focus on the case of framed manifolds (which are automatically Spin) and provide a formulation of the refined partition function using a tertiary index invariant, namely the f-invariant introduced by Laures within elliptic cohomology. We describe the context globally, connecting the various spaces and theories around M-theory, and providing a physical realization and interpretation of some ingredients appearing in the constructions due to Bunke-Naumann and Bodecker. The formulation leads to a natural interpretation of anomalies using corners and uncovers some resulting constraints in the heterotic corner. The analysis for type IIA leads to a physical identification of various components of eta-forms appearing in the formula for the phase of the partition function.

description: Zielsetzung Ziel dieser Arbeit war die Untersuchung der Assoziationen zwischen Advanced Glycation End Products (AGEs), ihren löslichen Rezeptoren (sRAGE) und dem Quotient AGE/sRAGE mit aktueller körperlicher Funktionsfähigkeit und Mortalität. Methoden Wir nutzten ordinale logistische Regressionsmodelle zur Untersuchung der Assoziationen zwischen AGEs, sRAGE und AGE/sRAGE mit körperlicher Funktionsfähigkeit und Kaplan-Meyer-Kurven sowie multivariable und zeitabhängige Cox-Regressionsanalysen, um die Assoziationen mit Mortalität zu untersuchen. Ergebnisse Höhere Serum-Konzentrationen von AGEs und dem AGEs/sRAGE Quotienten waren nur bei Frauen mit geringerer körperlicher Funktionsfähigkeit assoziiert. Die Cox-Regressionsanalysen ergaben keine Assoziationen von AGEs, sRAGE oder AGE/sRAGE mit Mortalität. Schlussfolgerungen Wir konnten eine stärkere und geschlechtsspezifische Assoziation des AGE-RAGE Systems mit aktuellen Outcomes im Vergleich zu chronischen Outcomes zeigen.
description: Aims We aimed to investigate the association between AGEs, their soluble receptors (sRAGE) and the AGE/sRAGE ratio with current and chronical outcomes in the general population using the examples of current physical activity and mortality. Methods We used ordinal logistic regression to examine associations between AGEs, sRAGE, and AGE/sRAGE ratio with physical functioning as well as Kaplan-Meyer survival curves and multivariable and time-varying Cox-regression to assess the associations with mortality. Results Higher levels of AGEs and AGE/sRAGE ratio were associated with lower physical functioning only in women. The cox-regression showed no association of AGEs, sRAGE or AGE/sRAGE with mortality. Conclusions We showed a stronger and sex-related association of the AGE-RAGE system with current outcomes than with chronical outcomes.

description: Background: This cross-sectional study examined gender differences in physical activity (PA), body mass index, sedentary behavior (SB), and academic performance (AP) in school-aged children in Qatar. Methods: Fifty-two schoolchildren (age: 11.9 ± 0.6 years) were assigned to gender-adjusted groups (female; n = 29). AP was calculated using the grade point averages (GPA) in Mathematics, Science, and Arabic. Additionally, the Short Form of the International Physical Activity Questionnaire (IPAQ) was utilized. Results: Four parameters (peak height velocity [PHV], science, Arabic, vigorous PA) showed relevant gender effects (p < 0.05 and ηp2 > 0.10). The largest gender effect was calculated for PHV (p < 0.001, ηp2 = 0.45). PHV was markedly higher for males (1.65 ± 0.90) than for females (0.36 ± 0.37). Females showed a higher performance level in science (82.9 ± 8.61 vs. 77.0 ± 8.76) and Arabic (80.9 ± 8.25 vs. 73.0 ± 8.22). A significant gender difference (p = 0.002, ηp2 = 0.18) was evident for vigorous MET-minutes/week (males: 1318 ± 932 vs. females: 646 ± 525). In conclusion, males exhibited the greatest amount of moderate and vigorous PA. Females spent the greatest time sitting. Arabic was different by gender, and science AP was dependent upon gender. Conclusions: These data suggest subjects in middle school are sensitive to gender, but not necessarily influenced by PA or SB at this age. Encouraging a school-based program and an after-school health club characterized by gender sensitive strategies consisting of a health class and physical education curriculum support the unique needs, interests of academic performance, and motor skills to improving health related fitness for girls compared to boys.

Predicting parameters in deep learning
Creators: name: Shakibi, Babak
Publisher: name: University of British Columbia
Year: 2014

description: The recent success of large and deep neural network models has motivated the training of even larger and deeper networks with millions of parameters. Training these models usually requires parallel training methods where communicating large number of parameters becomes one of the main bottlenecks. We show that many deep learning models are over-parameterized and their learned features can be predicted given only a small fraction of their parameters. We then propose a method which exploits this fact during the training to reduce the number of parameters that need to be learned. Our method is orthogonal to the choice of network architecture and can be applied in a wide variety of neural network architectures and application areas. We evaluate this technique using various experiments in image and speech recognition and show that we can only learn a fraction of the parameters (up to 10% in some cases) and predict the rest without a significant loss in the predictive accuracy of the model.

description: Objective: Understanding factors that impaired mental health during the COVID-19 pandemic is extremely relevant in order to mitigate long-term consequences of the pandemic and to promote resilience in future crises. Method: Data were collected in southern Germany in a population-based survey study (CoKoS) with three times of measurement in May 2020, November 2020 and July 2021. Predictors of depressive and anxiety symptoms were measured with a short version of the Patient Health Questionnaire (PHQ-4) in the general population (N = 758) and individuals who were infected with SARS-CoV-2 in the beginning of the pandemic (N = 412). We investigated differences between both samples and how stress components (worry, tension, demands and joy) measured with the Perceived Stress Questionnaire (PSQ) varied with depressive and anxiety symptoms over time. Three linear mixed models (GLMMs) were fitted to predict the PHQ-4 stepwise, including sociodemographic variables and stress (PSQ). Results: Depressive and anxiety symptoms increased from May 2020 to November 2020 and remained stable until July 2021. There were no differences between people with SARS-CoV-2 infection and the general population. Those with a pre-existing disease and lower education reported higher levels of depressive and anxiety symptoms. Stress explained a substantial fraction of variance in depressive and anxiety symptoms. The stress component worry emerged as the strongest predictor of depressive and anxiety symptoms, whereas joy seemed to buffer these symptoms. Conclusions: The results suggest that mitigating people’s worry and increasing joy may promote resilience in future crises. Future studies should assess mental health interventions targeted at vulnerable groups, such as those with lower socioeconomic status and poorer health.

description: Recently there has been a renewed activity in the physics of violations of Lorentz invariance in the neutrino sector. Flavor dependent Lorentz violation, which generically changes the pattern of neutrino oscillations, is extremely tightly constrained by oscillation experiments. Flavor independent Lorentz violation, which does not introduce new oscillation phenomena, is much more weakly constrained with constraints coming from time of flight and anomalous threshold analyses. We use a simplified rotationally invariant model to investigate the effects of finite baselines and energy dependent dispersion on anomalous reaction rates in long baseline experiments and show numerically that anomalous reactions do not necessarily cut off the spectrum quite as sharply as currently assumed. We also present a revised analysis of how anomalous reactions can be used to cast constraints from the observed atmospheric high energy neutrinos and the expected cosmogenic ones.

Development of Ojibwe (Anishinaabemowin) speech phase 1 : developing a word list to evaluate speech development
Creators: name: Kidd, Anne-Marie Elizabeth
Publisher: name: University of British Columbia
Year: 2014

description: First Nations children across Canada and the United States run the risk of being over-diagnosed or misdiagnosed for speech and/or language disorders due in part to a lack of knowledge about the culturally and linguistically relevant speech and language patterns of First Nations communities (Ball,Bernhardt, & Deby, 2007). Some children may speak a dialect of Ojibwe or a First Nations English Dialect influenced by Ojibwe and thus, speech-language pathologists (SLPs) and other educators need to ensure that each child receives linguistically and culturally suitable service. There are no linguistically and culturally relevant tools to assist in assessment and treatment of speech difficulties in Ojibwe-speaking children. This paper provides the first phase in the creation of a tool for speech (phonological) analysis of single-word elicitations from children for the Odawa dialect of Ojibwe. The tool is built on nonlinear phonology, whereby all aspects of the phonological system are represented in a multi-tiered hierarchy allowing for the analysis of speech patterns of both consonants, vowels and their features plus syllable and word structures (Bernhardt, et al., 2010). This paper had two purposes: to better understand the phonological system of this dialect; and to create a word list that could be used to examine the speech development of Odawa-Ojibwe speaking children. The full Ojibwe word list (n=90) consists of three word lists: a basic word list (with representation of most phonemes in all positions and word shapes); Extension A (with larger and more complex multisyllabic words); and Extension B (with smaller words). The phonological data showed some patterns that do not occur in English (or in some dialects of Ojibwe) that SLPs and educators should be aware of when working with this language: vowel syncope, complex consonant clusters; prevalance of nasals; and a fortis/lenis distinction. This paper provides the first phase in the development of an evaluation tool for use with Ojibwe-speaking children, and the template for other word list creations in other First Nations languages/dialects. The word list can be used clinically for descriptive purposes, though more research on use of this word list with children is needed.

Vacuum Stability Conditions From Copositivity Criteria

description: A scalar potential of the form $λ_{ab} ϕ_a^2 ϕ_b^2$ is bounded from below if its matrix of quartic couplings $λ_{ab}$ is copositive -- positive on non-negative vectors. Scalar potentials of this form occur naturally for scalar dark matter stabilised by a $\mathbb{Z}_2$ symmetry. Copositivity criteria allow to derive analytic necessary and sufficient vacuum stability conditions for the matrix $λ_{ab}$. We review the basic properties of copositive matrices and analytic criteria for copositivity. To illustrate these, we re-derive the vacuum stability conditions for the inert doublet model in a simple way, and derive the vacuum stability conditions for the $\mathbb{Z}_2$ complex singlet dark matter, and for the model with both a complex singlet and an inert doublet invariant under a global U(1) symmetry.

Robust dimension free isoperimetry in Gaussian space

Subjects: subject: Probability (math.PR)

description: We prove the first robust dimension free isoperimetric result for the standard Gaussian measure $γ_n$ and the corresponding boundary measure $γ_n^+$ in $\mathbb {R}^n$. The main result in the theory of Gaussian isoperimetry (proven in the 1970s by Sudakov and Tsirelson, and independently by Borell) states that if $γ_n(A)=1/2$ then the surface area of $A$ is bounded by the surface area of a half-space with the same measure, $γ_n^+(A)\leq(2π)^{-1/2}$. Our results imply in particular that if $A\subset \mathbb {R}^n$ satisfies $γ_n(A)=1/2$ and $γ_n^+(A)\leq(2π)^{-1/2}+δ$ then there exists a half-space $B\subset \mathbb {R}^n$ such that $γ_n(AΔB)\leq C\smash{\log^{-1/2}}(1/δ)$ for an absolute constant $C$. Since the Gaussian isoperimetric result was established, only recently a robust version of the Gaussian isoperimetric result was obtained by Cianchi et al., who showed that $γ_n(AΔB)\le C(n)\sqrtδ$ for some function $C(n)$ with no effective bounds. Compared to the results of Cianchi et al., our results have optimal (i.e., no) dependence on the dimension, but worse dependence on $ δ$.

description: Deep saline aquifers are promising geological reservoirs for CO2 sequestration if they do not leak. The absence of leakage is provided by the caprock integrity. However, CO2 injection operations may change the geomechanical stresses and cause fracturing of the caprock. We present a model for the propagation of a fracture in the caprock driven by the outflow of fluid from a low-permeability aquifer. We show that to describe the fracture propagation, it is necessary to solve the pressure diffusion problem in the aquifer. We solve the problem numerically for the two-dimensional domain and show that, after a relatively short time, the solution is close to that of one-dimensional problem, which can be solved analytically. We use the relations derived in the hydraulic fracture literature to relate the the width of the fracture to its length and the flux into it, which allows us to obtain an analytical expression for the fracture length as a function of time. Using these results we predict the propagation of a hypothetical fracture at the In Salah CO2 injection site to be as fast as a typical hydraulic fracture. We also show that the hydrostatic and geostatic effects cause the increase of the driving force for the fracture propagation and, therefore, our solution serves as an estimate from below. Numerical estimates show that if a fracture appears, it is likely that it will become a pathway for CO2 leakage.

description: Diese Arbeit untersucht die wechselseitigen Einflüsse von unterschiedlichen Gewebsfestigkeiten sowie einer variablen MRTF-A-Aktivität auf die Azinibildung von Brustepithelzellen. Humane MCF10A Azini und primäre Organoide aus der Maus wurden auf Matrices verschiedener Festigkeiten (200-4000 Pa) dreidimensional kultiviert. Die Kultur auf fester Collagen-I-Matrix ging mit der Bildung invasiver Protrusionen sowie einer erhöhten MRTF-A-Aktivität in MCF10A Azini einher. Diese festigkeitsabhängige Protrusionsbildung war erstmals auch in murinen Primärorganoiden zu beobachten und konnte in beiden Ansätzen mittels des MRTF-SRF-Inhibitors CCG 203971 partiell aufgehoben werden. Eine MRTF-A-Überexpression in den Primärorganoiden hingegen reduzierte die Protrusionsbildung auf fester Matrix und führte zu einer matrixübergreifenden Füllung der Organoide. Damit gibt diese Arbeit erste Hinweise auf das komplexe Wechselspiel zwischen MRTF-A und Gewebsfestigkeit in Brustazini.
description: In this study we analyzed the mutual interaction of different matrix stiffnesses and MRTF‐A activities on formation and maintenance of mammary acini. Human MCF10A acini and primary organoids isolated from murine mammary glands were cultivated in 3D on soft and stiff matrices (200–4000 Pa) in conjunction with the Rho/MRTF/SRF pathway inhibitor CCG 203971 and genetic activation of MRTF‐A. 3D growth on stiff collagen matrices was accompanied by increased MRTF‐A activity and formation of invasive protrusions in MCF10A acini. Stiffness‐induced protrusion formation was also observed in murine mammary organoids. Acinar outgrowth in both the MCF10A acini and the primary organoids was partially reverted by treatment with CCG 203971. However, genetic activation of MRTF‐A in the primary acini reduced protrusion formation on stiff matrices, whilst it strongly promoted luminal filling matrix‐independently. This work suggests an intricate crosstalk between matrix stiffness and MRTF‐A.

description: This article presents an algorithm that generates a conservative confidence interval of a specified length and coverage probability for the power of a Monte Carlo test (such as a bootstrap or permutation test). It is the first method that achieves this aim for almost any Monte Carlo test. Previous research has focused on obtaining as accurate a result as possible for a fixed computational effort, without providing a guaranteed precision in the above sense. The algorithm we propose does not have a fixed effort and runs until a confidence interval with a user-specified length and coverage probability can be constructed. We show that the expected effort required by the algorithm is finite in most cases of practical interest, including situations where the distribution of the p-value is absolutely continuous or discrete with finite support. The algorithm is implemented in the R-package simctest, available on CRAN.

description: The actin-regulated transcription factor MRTF-A represents a central relay in mechanotransduction and controls a subset of SRF-dependent target genes. However, gain-of-function studies in vivo are lacking. Here we characterize a conditional MRTF-A transgenic mouse model. While MRTF-A gain-of-function impaired embryonic development, induced expression of constitutively active MRTF-A provoked rapid hepatocyte ballooning and liver failure in adult mice. Specific expression in the intestinal epithelium caused an erosive architectural distortion, villus blunting, cryptal hyperplasia and colonic inflammation, resulting in transient weight loss. Organoids from transgenic mice repeatedly induced in vitro showed impaired self-renewal and defective cryptal compartments. Mechanistically, MRTF-A gain-of-function decreased proliferation and increased apoptosis, but did not induce fibrosis. MRTF-A targets including Acta2 and Pai-1 were induced, whereas markers of stem cells and differentiated cells were reduced. Our results suggest that activated MRTF-A in the intestinal epithelium shifts the balance between proliferation, differentiation and apoptosis.
Highly flexible top-emitting phosphorescent organic light emitting diodes (OLEDs)

description: Organic Light Emitting Diodes (OLEDs) have become attractive for flat panel display industry, with applications ranging from mobile phone screens to TVs. They have several advantages over inorganic LEDs such as high contrast ratio, wide viewing angle, faster response time, scalable large area processing and most importantly mechanical flexibility. OLEDs on flexible substrates can endure certain level of mechanical deformation such as bending, rolling or folding without disruption of the performance. The current demonstrated flexibility for OLEDs is up to a few centimeters or millimeters bending radius, depending on the materials, substrates and device structures. More flexible OLEDs with bending radius of curvature on the order of microns will be needed for applications in wearable, roll-up, or foldable displays and bezel-free screens and flexible signage systems. This thesis presents the design, fabrication and characterization of highly flexible and foldable top-emitting OLEDs made on 50 micron thick polyimide (PI) plastic substrates, which can achieve approximately 200 microns bending radius of curvature (folding) without visible damage or impact on emission brightness and uniformity. To the best of our knowledge these are the most flexible phosphorescent OLEDs and first foldable OLEDs ever reported. We believe such flexibility is the benefit of the mechanical stability and low film thickness of the PI substrate. The surface roughness of PI had been the major limitation of its application as OLED substrates, and in this thesis a special side-angle evaporation method is proposed to improve the step coverage of deposited thin films of materials on PI without the requirement of buffer layers. The same method is also proved to be applicable for fabricating OLEDs on much rougher substrates such as Scotch tapes, and fiberglass and transparency sheets. The OLEDs fabricated on above substrates are also presented and characterized.

Meaning-making of historical episodes by the Punjabi-Sikh youth in Vancouver
Creators: name: Srivastava, Shambhavi
Publisher: name: University of British Columbia
Year: 2014

description: This thesis explores the ways in which the youth from the Punjabi-Sikh community in Vancouver, Canada relate to three historical episodes associated with the community, namely, ‘Events of 1984’(The Indian Army’s 1984 attack on the Golden Temple in Amritsar, as well as, the anti-Sikh riots in Delhi, India), ‘Events of 1985’ (The Air India bombings) and the Komagata Maru episode of 1914. Exploring the youth narratives and non-narratives on these violent episodes intrinsically connected with the Sikh diasporic community in Canada, provides for an analysis of the meaning-making processes that the youth engage with to make sense of these episodes. By emphasizing on how the youth remember, what they remember (and what they forget), I draw attention to linkages between these processes of recall and the present day realities of the youth. By juxtaposing the dominant narratives on the episodes with the youth narratives, the research also explores the relationship of these ‘grand’ narratives with the personal narratives of the youth, the space and reception of the contending forms of remembrances of these violent histories, and its effect on present day politics.

description: The B-(curl-)mode of the correlation of galaxy ellipticities (shear) can be used to detect a stochastic gravitational wave background, such as that predicted by inflation. In this paper, we derive the tensor mode contributions to shear from both gravitational lensing and intrinsic alignments, using the gauge-invariant, full-sky results of arXiv:1204.3625. We find that the intrinsic alignment contribution, calculated using the linear alignment model, is larger than the lensing contribution by an order of magnitude or more, if the alignment strength for tensor modes is of the same order as for scalar modes. This contribution also extends to higher multipoles. These results make the prospects for probing tensor modes using galaxy surveys less pessimistic than previously thought, though still very challenging.

description: Introduction: Cardiac resynchronization therapy (CRT) with biventricular pacing (BiV-CRT) is ineffective in approximately one-third of patients. CRT with Conduction system pacing (CSP-CRT) may achieve greater synchronization. We aimed to assess the effectiveness of CRT with His pacing (His-CRT) or left bundle branch pacing (LBB-CRT) in lieu of biventricular CRT. Methods and Results: The PubMed, Embase, Web of Science, Scopus, and the Cochrane Library were systematically searched until August 19, 2023, for original studies including patients with reduced left ventricular ejection fraction (LVEF) who received His- or LBB-CRT, that reported either CSP-CRT success, LVEF, QRS duration (QRSd), or New York Heart Association (NYHA) classification. Effect measures were compared with frequentist network meta-analysis. Thirty-seven publications, including 20 comparative studies, were included. Success rates were 73.5% (95% CI: 61.2–83.0) for His-CRT and 91.5% (95% CI: 88.0–94.1) for LBB-CRT. Compared to BiV-CRT, greater improvements were observed for LVEF (mean difference [MD] for His-CRT +3.4%; 95% CI [1.0; 5.7], and LBB-CRT: +4.4%; [2.5; 6.2]), LV end-systolic volume (His-CRT:17.2mL [29.7; 4.8]; LBB-CRT:15.3mL [28.3; 2.2]), QRSd (His-CRT: –17.1ms [–25.0; –9.2]; LBB-CRT: –17.4ms [–23.2; –11.6]), and NYHA (Standardized MD [SMD]: His-CRT:0.4 [0.8; 0.1]; LBB-CRT:0.4 [–0.7; –0.2]). Pacing thresholds at baseline and follow-up were significantly lower with LBB-CRT versus both His-CRT and BiV-CRT. CSP-CRT was associated with reduced mortality (R = 0.75 [0.61–0.91]) and hospitalizations risk (RR = 0.63 [0.42–0.96]). Conclusion: This study found that CSP-CRT is associated with greater improvements in QRSd, echocardiographic, and clinical response. LBB-CRT was associated with lower pacing thresholds. Future randomized trials are needed to determine CSP-CRT efficacy.
