description: We report on a capacitance study of dual gated bilayer graphene. The measured capacitance allows us to probe the electronic compressibility as a function of carrier density, temperature, and applied perpendicular electrical displacement D. As a band gap is induced with increasing D, the compressibility minimum at charge neutrality becomes deeper but remains finite, suggesting the presence of localized states within the energy gap. Temperature dependent capacitance measurements show that compressibility is sensitive to the intrinsic band gap. For large displacements, an additional peak appears in the compressibility as a function of density, corresponding to the presence of a 1-dimensional van Hove singularity (vHs) at the band edge arising from the quartic bilayer graphene band structure. For D > 0, the additional peak is observed only for electrons, while D < 0 the peak appears only for holes. This asymmetry that can be understood in terms of the finite interlayer separation and may be useful as a direct probe of the layer polarization.

description: Single-field slow-roll inflation with a non-vacuum initial state has an enhanced bispectrum in the local limit. We numerically calculate the local-type fNL signal in the CMB that would be measured for such models (including the full transfer function and 2D projection). The nature of the result depends on several parameters, including the occupation number N_k, the phase angle θ_k between the Bogoliubov parameters, and the slow-roll parameter ε. In the most conservative case, where one takes θ_k \approx η_0 k (justified by physical reasons discussed within) and ε\lesssim 0.01, we find that 0 < fNL < 1.52 (ε/0.01), which is likely too small to be detected in the CMB. However, if one is willing to allow a constant value for the phase angle θ_k and N_k=O(1), fNL can be much larger and/or negative (depending on the choice of θ_k), e.g. fNL \approx 28 (ε/0.01) or -6.4 (ε/0.01); depending on ε, these scenarios could be detected by Planck or a future satellite. While we show that these results are not actually a violation of the single-field consistency relation, they do produce a value for fNL that is considerably larger than that usually predicted from single-field inflation.

description: Verizon Media (VZM) native advertising is one of VZM largest and fastest growing businesses, reaching a run-rate of several hundred million USDs in the past year. Driving the VZM native models that are used to predict event probabilities, such as click and conversion probabilities, is OFFSET - a feature enhanced collaborative-filtering based event-prediction algorithm. In this work we focus on the challenge of predicting click-through rates (CTR) when we are aware that some of the clicks have short dwell-time and are defined as accidental clicks. An accidental click implies little affinity between the user and the ad, so predicting that similar users will click on the ad is inaccurate. Therefore, it may be beneficial to remove clicks with dwell-time lower than a predefined threshold from the training set. However, we cannot ignore these positive events, as filtering these will cause the model to under predict. Previous approaches have tried to apply filtering and then adding corrective biases to the CTR predictions, but did not yield revenue lifts and therefore were not adopted. In this work, we present a new approach where the positive weight of the accidental clicks is distributed among all of the negative events (skips), based on their likelihood of causing accidental clicks, as predicted by an auxiliary model. These likelihoods are taken as the correct labels of the negative events, shifting our training from using only binary labels and adopting a binary cross-entropy loss function in our training process. After showing offline performance improvements, the modified model was tested online serving VZM native users, and provided 1.18% revenue lift over the production model which is agnostic to accidental clicks.

Health system integration and equity-based services to support women who experience marginalization and IPV
Creators: name: Davila Lara, G. Yazmin
Publisher: name: University of British Columbia
Year: 2022

description: In 2015, the WHO released a call to action to stop violence against women. This call to action has been translated into initiatives to improve health and social policies and services. Health system integration, defined as the process to improve healthcare performance, can better organize and integrate the care of people, especially those experiencing inequities. For women who experience marginalization and intimate partner violence (IPV), health system integration has the potential to address inequities. This dissertation involved three phases to illuminate how health system integration and equity-based services can support women who experience marginalization and IPV. Phase 1 (Scoping Review), involved a comprehensive review of Canadian literature on health system integration and equity-based services to meet women’s needs. Phase 2 (Policy Analysis), involved the analysis of publicly available documents for the design and delivery of services related to the care for women in British Columbia (BC). Phase 3 (Discussion Session), involved a virtual session with women and relevant contributors to gather their insights, and develop recommendations for action in the Southern Interior of BC. Results demonstrated: a) services based on health equity limited social exclusion by supporting women’s healing processes; b) understanding the diversity of the needs of multiple groups of women is essential for women-centred care; c) providers often did not recognize the complexity of women’s experiences and reproduced systemic violence; d) a cross-sectoral approach facilitated the approval of policy actions related to care for women in BC. Key recommendations included: implementing a formal process of integrating women’s voices and direction in the design of policies and services locally, provincially, and nationally; and reinforcing trauma- and violence-informed care across sectors and levels of care. To limit further inequities, community-based approaches that consider preventive actions are fundamental to challenge violence, and enhancements in housing, justice, and financial supports are needed.

description: We consider random walks in random Dirichlet environment (RWDE) which is a special type of random walks in random environment where the exit probabilities at each site are i.i.d. Dirichlet random variables. On ${\mathbb Z}^d$, RWDE are parameterized by a 2d-uplet of positive reals called weights. In this paper, we characterize for $d\ge 3$ the weights for which there exists an absolutely continuous invariant probability for the process viewed from the particle. We can deduce from this result and from [27] a complete description of the ballistic regime for $d\ge 3$.

Cerebral and peripheral vascular responses to hypercapnia
Creators: name: Carr, Jordan Mark John Ramone
Publisher: name: University of British Columbia
Year: 2022

description: During hypercapnia (elevated partial pressure of arterial CO₂; PaCO₂) cerebral blood flow (CBF) is elevated in order to maintain pH in the cerebral tissues; mean arterial pressure (MAP), minute ventilation (Vᴇ), and heart rate also increase. The shearing force caused by blood flowing through arteries also influences haemodynamics in the vasculature throughout the body, in a regionally varied manner. These PaCO₂, MAP, and shear stress-mediated responses are becoming relatively well understood, though the integration of such responses in both cerebral and peripheral vasculatures simultaneously has mostly been ignored. As hypercapnia causes both cerebral and systemic effects, which are inextricably connected, this thesis compared and contrasted hypercapnic-mediated responses between the cerebral and peripheral vasculatures, with recourse to the various influences of shear stress, MAP, and Vᴇ. Study one examined vascular responses to shear stress in cerebral and peripheral conduit arteries, comparing these against the hypercapnia-mediated response in the cerebral vasculature. The findings revealed that neither brachial artery shear-mediated vasodilation nor CBF reactivity to CO₂ were correlated with cerebral shear-mediated function. In Study two, via retrospective analyses, we assessed the within-test stability of CBF responses to CO₂ using dynamic end-tidal forcing, demonstrating that CBF responses to CO₂ do not fluctuate unless the CO₂ stimulus does. Study three investigated the influence of acute reductions in arterial oxygen (O₂) content on CBF responses to PaCO₂. Here, acute anemia elevated basal CBF which maintained cerebral O₂ delivery and elevated cerebral CO₂ washout. Study 4A assessed the peripheral vascular response to hypercapnia while accounting for the influences of shear stress and sympathetic nervous adrenergic activity (which controls MAP). We found that peripheral vascular responses to hypercapnia are suppressed by adrenergic innervation. Study 4B then extended these findings to address the influence of adrenergic activity on cerebral shear-mediated and hypercapnic responses, and found that, unlike peripheral vascular responses, α1-adrenoreceptors do not influence the cerebral blood flow response to CO₂, but may cause internal carotid artery (ICA) vascular restraint. In summary, the regionally heterogenous blood flow and vasodilator responses to both hypercapnia and shear stress are indicative of the differential balance of end-organ perfusion requirements and conduit artery vasodilator reserve. This dissertation advances our knowledge of the integration of hypercapnia, shear stress, and sympathetic nervous activity in healthy humans.

description: Shear induced orientational ordering of asymmetric elongated particles is investigated experimentally. Corn grains and pegs with one end sharpened are studied using X-ray Computed Tomography (CT) during quasistatic shearing and silo discharge. We show that asymmetries can be detected in the orientational distributions of the particles, which are related to the modulated rotation of the particles during shear flow. Namely, when the particles rotate in a plane that is not horizontal, they spend more time with the sharper (lighter) end pointing up, which can be explained using energetic arguments. We quantify the resulting asymmetry of the orientational distribution in a split bottom Couette cell and in a silo discharge process.

description: We analyze the spontaneous magnetization reversal of supported monoatomic chains of finite length due to thermal fluctuations via atomistic spin-dynamics simulations. Our approach is based on the integration of the Landau-Lifshitz equation of motion of a classical spin Hamiltonian at the presence of stochastic forces. The associated magnetization lifetime is found to obey an Arrhenius law with an activation barrier equal to the domain wall energy in the chain. For chains longer than one domain-wall width, the reversal is initiated by nucleation of a reversed magnetization domain primarily at the chain edge followed by a subsequent propagation of the domain wall to the other edge in a random-walk fashion. This results in a linear dependence of the lifetime on the chain length, if the magnetization correlation length is not exceeded. We studied chains of uniaxial and tri-axial anisotropy and found that a tri-axial anisotropy leads to a reduction of the magnetization lifetime due to a higher reversal attempt rate, even though the activation barrier is not changed.

description: Yahoo's native advertising (also known as Gemini native) serves billions of ad impressions daily, reaching a yearly run-rate of many hundred of millions USD. Driving the Gemini native models that are used to predict both click probability (pCTR) and conversion probability (pCONV) is OFFSET - a feature enhanced collaborative-filtering (CF) based event prediction algorithm. \offset is a one-pass algorithm that updates its model for every new batch of logged data using a stochastic gradient descent (SGD) based approach. Since OFFSET represents its users by their features (i.e., user-less model) due to sparsity issues, rule based hard frequency capping (HFC) is used to control the number of times a certain user views a certain ad. Moreover, related statistics reveal that user ad fatigue results in a dramatic drop in click through rate (CTR). Therefore, to improve click prediction accuracy, we propose a soft frequency capping (SFC) approach, where the frequency feature is incorporated into the OFFSET model as a user-ad feature and its weight vector is learned via logistic regression as part of OFFSET training. Online evaluation of the soft frequency capping algorithm via bucket testing showed a significant 7.3% revenue lift. Since then, the frequency feature enhanced model has been pushed to production serving all traffic, and is generating a hefty revenue lift for Yahoo Gemini native. We also report related statistics that reveal, among other things, that while users' gender does not affect ad fatigue, the latter seems to increase with users' age.

description: KASCADE-Grande, the extension of the multi-detector setup of KASCADE, was devoted to measure the properties of extensive air showers initiated by high-energy cosmic rays in the primary energy range of 1 PeV up to 1 EeV. The observations of the energy spectrum and mass composition of cosmic rays contribute with great detail to the understanding of the transition from galactic to extragalactic origin of cosmic rays, and furthermore to validate the properties of hadronic interaction models in the air shower development. Although the experiment is fully dismantled, the analysis of the entire KASCADE-Grande data set continues. We have recently investigated the impact of different post-LHC hadronic interaction models, QGSJETII-04, EPOS-LHC, Sibyll 2.3d, on air shower predictions in terms of the reconstructed spectra of heavy and light primary masses, including systematic uncertainties. In addition, the conversely discussed evolution of the muon content of high-energy air showers in the atmosphere is compared with the predictions of different interaction models. In this contribution, the latest results from the KASCADE-Grande measurements will be discussed.

description: With the goal of giving evidence for the theoretical consistency of the Horava Theory, we perform a Hamiltonian analysis on a classical model suitable for analyzing its effective dynamics at large distances. The model is the lowest-order truncation of the Horava Theory with the detailed-balance condition. We consider the pure gravitational theory without matter sources. The model has the same potential term of general relativity, but the kinetic term is modified by the inclusion of an arbitrary coupling constant lambda. Since this constant breaks the general covariance under space-time diffeomorphisms, it is believed that arbitrary values of lambda deviate the model from general relativity. We show that this model is not a deviation at all, instead it is completely equivalent to general relativity in a particular partial gauge fixing for it. In doing this, we clarify the role of a second-class constraint of the model.

Conservation constrained : protecting British Columbia's endangered caribou in a political-economy of extraction
Creators: name: DiSilvestro, Adriana Maria
Publisher: name: University of British Columbia
Year: 2022

description: Intensifying resource extraction poses an existential threat to the world’s biodiversity. This threat is exemplified in the case of British Columbia’s (BC) endangered woodland caribou herds (Rangifer tarandus), which are facing extirpation due to extraction-driven habitat destruction, primarily from oil & gas development and forest harvest. Notably, the decline of BC’s caribou is occurring despite the fact that they are both federally protected under the Species at Risk Act (SARA), and subject to a number of intensive conservation initiatives. In this thesis, I explore how caribou declines are occurring despite existing legal protections by examining how the province’s apparent economic reliance on resource extraction shapes available conservation solutions. To do so, I conduct a two part inquiry using a combination of Critical GIS and policy and textual analysis. First, I quantify the extent to which the province subsidizes oil & gas activities in federally designated critical caribou habitat. Then, I examine the province's dominant conservation solution to caribou endangerment, wolf culling, and unpack its relationship to BC’s extractive regime. Ultimately I find that from 2019-2021, subsidized oil & gas activities were occurring in critical caribou habitat. Additionally, drawing from existing literature on socio-ecological fixes, I demonstrate that because the provincial wolf cull does not challenge the root cause of defaunation, yet fulfills the state’s mandate for conservation action, it ultimately works to sustain the extractive status quo. Overall, this work demonstrates that the apparent economic imperative of resource extraction in British Columbia both undercuts the potential for comprehensive solutions to caribou declines, such as habitat protection, and constrains the realm of possible interventions to those that do not inhibit further extraction. In doing so this research contributes to questions of how global defaunation continues to accelerate despite an increase in legal mechanisms designed to protect vulnerable species and ecosystems.

description: We investigate the time-dependent fluctuations of the electric current injected from a reservoir with a non-equilibrium spin accumulation into a mesoscopic conductor. We show how the current noise power directly reflects the magnitude of the spin accumulation in two easily noticeable ways. First, as the temperature is lowered, the small-bias noise saturates at a value determined by the spin accumulation. Second, in the presence of spin-orbit interactions in the conductor, the current noise exhibits a sample-dependent mesoscopic asymmetry under reversal of the electric current direction. These features provide for a purely electric protocol for measuring spin accumulations.

description: We study a model of consensus decision making, in which a finite group of Bayesian agents has to choose between one of two courses of action. Each member of the group has a private and independent signal at his or her disposal, giving some indication as to which action is optimal. To come to a common decision, the participants perform repeated rounds of voting. In each round, each agent casts a vote in favor of one of the two courses of action, reflecting his or her current belief, and observes the votes of the rest. We provide an efficient algorithm for the calculation the agents have to perform, and show that consensus is always reached and that the probability of reaching a wrong decision decays exponentially with the number of agents.

description: Aim: To illuminate the lived experiences of Indonesian nurses who previously worked as caregivers in Japanese residential care facilities, by exploring the journey of becoming returnees. Background: The creation of bilateral agreements between Indonesia and Japan has facilitated the movement of Indonesian nurses to work as caregivers in Japan since 2008. While this decision raised concerns with regard to the degradation of nursing skills, little is known about this issue from the perspective of nurse returnees and how the experience affects their life. Method: A hermeneutic phenomenological method was employed for this study. A purposive sample of 15 Indonesian nurse returnees participated in this study. Semi-structured interviews were conducted in four of Indonesia's provinces between August and October 2015. Data were analysed thematically, supported by QSR NVIVO 10 software. Findings: Four key themes emerged from the data analysis: (i) returning home; (ii) going back to zero; (iii) walking through a difficult journey; and (iv) overcoming barriers. These findings described the lived experiences of nurse returnees when they got back to the country of origin. Conclusion: Indonesian nurse returnees experienced deskilling and struggled to re-enter the nursing profession or to find other non-nursing jobs. The significant impact of this migration on individual nurses with regard to maximizing the benefits of return migration deserves further investigation. Implication for nursing and health policy: The Indonesian government, jointly with other stakeholders, should develop a brain gain strategy to align returnees’ expertise with the needs of the national labour market. The public-private partnership should be strengthened to utilize returnees in healthcare services.

description: In this paper we investigate undirected discrete graphical tree models when all the variables in the system are binary, where leaves represent the observable variables and where all the inner nodes are unobserved. A novel approach based on the theory of partially ordered sets allows us to obtain a convenient parametrization of this model class. The construction of the proposed coordinate system mirrors the combinatorial definition of cumulants. A simple product-like form of the resulting parametrization gives insight into identifiability issues associated with this model class. In particular, we provide necessary and sufficient conditions for such a model to be identified up to the switching of labels of the inner nodes. When these conditions hold, we give explicit formulas for the parameters of the model. Whenever the model fails to be identified, we use the new parametrization to describe the geometry of the unidentified parameter space. We illustrate these results using a simple example.

description: With 87-Sr atoms confined in a one dimensional optical lattice, the frequency of the optical clock transition 5s^2 ^1S_0 - 5s5p ^3P_0 has been determined to be 429 228 004 229 872.9(5) Hz. The transition frequency was measured with the help of a fs-frequency comb against one of PTB's H-masers whose frequency was measured simultaneously by the PTB Cs fountain clock CSF1. The Sr optical frequency standard contributes with a fractional uncertainty of 1.5 10^-16 to the total uncertainty. The agreement of the measured transition frequency with previous measurements at other institutes supports the status of this transition as secondary representation of the second with the currently smallest uncertainty.

description: Account Management System is a software developed for daily student attendance in schools, colleges, and institutes. If facilitates to access the attendance information of a particular student in a particular class. The information is sorted by the operators, which will be provided by the teacher for a particular class. This system will also help in evaluating attendance eligibility criteria of a student. In the present system, all work is done on paper. The whole session attendance is stored in the register and at the end of the session the reports are generated and the students who don’t have 75% attendance get a notice. The existing system is not user-friendly because the retrieval of data is very slow and data is not maintained efficiently. We require more calculations to generate the report so it is generated at the end of the session. And the students do not get a single chance to improve their attendance. All calculations to generate report are done manually so there is a greater chance of errors. The existing system requires a lot of paperwork. Loss of even a single register/record led to a difficult situation because all the papers are needed to generate the reports. Every work is done manually so we cannot generate the report in the middle of the session or as per the requirement because it is very time-consuming. The proposed system is user-friendly because the retrieval and storing of data is fast and data is maintained efficiently. Moreover, the graphical user interface is provided in the proposed system, which provides the user to deal with the system very easily. Reports can be easily generated in the proposed system so the user can generate their port as per the requirement (monthly) or in the middle of the session. User can give the notice to the students so he/she becomes regular.

Linear Stability Analysis and the Speed of Gravitational Waves in Dynamical Chern-Simons Modified Gravity

description: We perform a linear stability analysis of dynamical Chern-Simons modified gravity in the geometric optics approximation and find that it is linearly stable on the backgrounds considered. Our analysis also reveals that gravitational waves in the modified theory travel at the speed of light in Minkowski spacetime. However, on a Schwarzschild background the characteristic speed of propagation along a given direction splits into two modes, one subluminal and one superluminal. The width of the splitting depends on the azimuthal components of the propagation vector, is linearly proportional to the mass of the black hole, and decreases with the third inverse power of the distance from the black hole. Radial propagation is unaffected, implying that as probed by gravitational waves the location of the event horizon of the spacetime is unaltered. The analysis further reveals that when a high frequency, pure gravitational wave is scattered from a black hole, a scalar wave of comparable amplitude is excited, and vice-versa.

description: Edwin Hubble is often credited with discovering the expanding Universe based on spectra taken by him. This statement is incorrect and we feel that it is the responsibility of those who are aware of the historical facts to set the record straight.

description: The partition function of N=6 supersymmetric Chern-Simons-matter theory (known as ABJM theory) on S^3, as well as certain Wilson loop observables, are captured by a zero dimensional super-matrix model. This super-matrix model is closely related to a matrix model describing topological Chern-Simons theory on a lens space. We explore further these recent observations and extract more exact results in ABJM theory from the matrix model. In particular we calculate the planar free energy, which matches at strong coupling the classical IIA supergravity action on AdS_4 x CP^3 and gives the correct N^{3/2} scaling for the number of degrees of freedom of the M2 brane theory. Furthermore we find contributions coming from world-sheet instanton corrections in CP^3. We also calculate non-planar corrections, both to the free energy and to the Wilson loop expectation values. This matrix model appears also in the study of topological strings on a toric Calabi-Yau manifold, and an intriguing connection arises between the space of couplings of the planar ABJM theory and the moduli space of this Calabi-Yau. In particular it suggests that, in addition to the usual perturbative and strong coupling (AdS) expansions, a third natural expansion locus is the line where one of the two 't Hooft couplings vanishes and the other is finite. This is the conifold locus of the Calabi-Yau, and leads to an expansion around topological Chern-Simons theory. We present some explicit results for the partition function and Wilson loop observables around this locus.

description: During recent years, there here has been a boom in terms of deep learning use for handwriting analysis and recognition. One main application for handwriting analysis is early detection and diagnosis in the health field. Unfortunately, most real case problems still suffer a scarcity of data, which makes difficult the use of deep learning-based models. To alleviate this problem, some works resort to synthetic data generation. Lately, more works are directed towards guided data synthetic generation, a generation that uses the domain and data knowledge to generate realistic data that can be useful to train deep learning models. In this work, we combine the domain knowledge about the Alzheimer's disease for handwriting and use it for a more guided data generation. Concretely, we have explored the use of in-air movements for synthetic data generation.
TUMOR TARGETING VIA INTEGRIN LIGANDS: SYNTHESIS AND BIOLOGICAL EVALUATION OF RGD PEPTIDOMIMETIC-DRUG CONJUGATES

description: Peptides and peptidomimetics bearing the Arg-Gly-Asp peptide sequence have been demonstrated to bind with high affinity to ?v?3 Integrin, a heterodimeric transmembrane receptor overexpressed in several tumor cells. For these reasons, integrin ligands have been coupled to a variety of anticancer drugs, aiming at the selective delivery of the payload at the tumor site. This PhD work describes the conjugation of the peptidomimetic ?v?3 Integrin ligand cyclo[DKP-RGD] to different anticancer drugs (i.e. paclitaxel, daunorubicin and camptothecin) through peptide and disulfide linkers. The resulting small molecule-drug conjugates (SMDCs) are selective ?v?3 binders and are able to release the drug upon exposure to lysosomal enzymes (e.g. cysteine proteases) or intracellular reducing agents (e.g. glutathione). Cell proliferation assays against isogenic human cancer cells expressing ?v?3 at different levels (?v?3 +/?v?3 ?) have been performed to evaluate the selective cytotoxic activity of RGD-based SMDCs against integrin-positive cancer cells. Fairly effective integrin targeting was displayed by the cyclo[DKP-RGD]-Val-Ala-PTX conjugate (compound 80), which was found to differentially inhibit proliferation in antigen-positive CCRF CEM ?v?3 versus antigen-negative isogenic CCRF-CEM cells. Next-generation cyclo[DKP-RGD]-Drug conjugates were prepared, aiming at improving the targeting effect shown by the cyclo[DKP-RGD]-Val-Ala-PTX conjugate as well as to deeply analyze the SMDC?s interactions with cancer cells.

description: We consider a queueing network in which there are constraints on which queues may be served simultaneously; such networks may be used to model input-queued switches and wireless networks. The scheduling policy for such a network specifies which queues to serve at any point in time. We consider a family of scheduling policies, related to the maximum-weight policy of Tassiulas and Ephremides [IEEE Trans. Automat. Control 37 (1992) 1936--1948], for single-hop and multihop networks. We specify a fluid model and show that fluid-scaled performance processes can be approximated by fluid model solutions. We study the behavior of fluid model solutions under critical load, and characterize invariant states as those states which solve a certain network-wide optimization problem. We use fluid model results to prove multiplicative state space collapse. A notable feature of our results is that they do not assume complete resource pooling.
