description: Given the volatility of the stock market and the multitude of financial variables at play, forecasting the value of stocks can be a challenging task. Nonetheless, such prediction task presents a fascinating problem to solve using machine learning. The stock market can be affected by news events, social media posts, political changes, investor emotions, and the general economy among other factors. Predicting the stock value of a company by simply using financial stock data of its price may be insufficient to give an accurate prediction. Investors often openly express their attitudes towards various stocks on social medial platforms. Hence, combining sentiment analysis from social media and the financial stock value of a company may yield more accurate predictions. This thesis proposes a method to predict the stock market using sentiment analysis and financial stock data. To estimate the sentiment in social media posts, we use an ensemble-based model that leverages Multi-Layer Perceptron (MLP), Long Short-Term Memory (LSTM), and Convolutional Neural Network (CNN) models. We use an LSTM model for the financial stock prediction. The models are trained on the AAPL, CSCO, IBM, and MSFT stocks, utilizing a combination of the financial stock data and sentiment extracted from social media posts on Twitter between the years 2015-2019. Our experimental results show that the combination of the financial and sentiment information can improve the stock market prediction performance. The proposed solution has achieved a prediction performance of 74.3%.

description: Objectives: Undertake a scoping review to determine the effectiveness of community-centred interventions designed to improve the mental health and well-being of adults from ethnic minority groups in the UK. Methods: We searched six electronic academic databases for studies published between January 1990 and September 2019: Medline, Embase, PsychINFO, Scopus, CINAHL and Cochrane. For intervention description and data extraction we used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist and Template for Intervention Description and Replication guide. Quality was assessed using Cochrane risk of bias tools. Grey literature results were deemed beyond the scope of this review due to the large number of interventions and lack of available outcomes data. Results: Of 4501 studies, 7 met the eligibility criteria of UK-based community interventions targeting mental health in adults from ethnic minority populations: four randomised controlled trials, one pre/post-pilot study, one cross-sectional study and one ethnographic study. Interventions included therapy-style sessions, peer-support groups, educational materials, gym access and a family services programme. Common components included a focus on tackling social isolation, using lay health workers from within the community, signposting and overcoming structural barriers to access. Four studies reported a statistically significant positive effect on mental health outcomes and six were appraised as having a high risk of bias. Study populations were ethnically heterogeneous and targeted people mainly from South Asia. No studies examined interventions targeting men. Conclusions: There is a paucity of high-quality evidence regarding community-centred interventions focused on improving public mental health among ethnic minority groups. Decision makers need scientific evidence to inform effective approaches to mitigating health disparities. Our next steps are to map promising community activities and interventions that are currently being provided to help identify emerging evidence.
Exploring Prenatal Nutrition Counseling Using a Human Factors Approach
Creators: name: Erbe, Katherine
Publisher: name: University of Illinois at Chicago

description: Abstract
Introduction: Pregnancy people may be uniquely motivated to make positive lifestyle choices, and obstetric providers are positioned to offer support and information. Multiple contextual factors impact prenatal nutrition counseling, yet little is known about the provider-pregnant person interactions during prenatal nutrition counseling. The field of human factors (HF) considers people’s abilities, characteristics, and limitations with the equipment they use, environments in which they function, and jobs they perform. Using a HF approach, this study examined in real-time patient-provider interactions related to prenatal nutrition counseling at the initial prenatal visit.
Methods: A convergent mixed methods longitudinal study using a HF framework was conducted. Initial pregnancy visits among a sample of obstetric providers at two large urban university clinics were observed and audio recorded from January to April 2023. Observed providers were interviewed and surveyed to evaluate their knowledge and practices related to pregnancy nutrition counseling; additional providers completed surveys. Patients were interviewed immediately after the visit to capture their comprehension, understanding, and perspectives related to prenatal nutrition.
Results: Sixteen providers participated in the observations, including seven nurse-midwives (n=7), attending physicians (n=5), and resident physicians (n=4), and a diverse group of pregnant people (n=20) was recruited. Forty-five providers completed surveys. Themes of communication, content, and inconsistencies were identified in how pregnancy nutrition counseling was completed. Providers made efforts to provide patient-centered pregnancy nutrition counseling, but most discussions were brief, generic, and provider-centered. While patients reported satisfaction with their providers and the information received, there were multiple knowledge gaps and missed patient contextual factors.
Discussion: Inadequate provider training and limited time in visits left many gaps in the provision of pregnancy nutrition counseling. A HF framework is a novel approach to investigating how providers approach pregnancy nutrition counseling and may be useful in researching patient-centered approaches to dietary habits that include contextual factors.

description: Reaction paths and classical and quantum trajectories are studied within a generalized Hamilton-Jacobi framework, which allows to put on equal footing topology and dynamics in chemical reactivity problems. In doing so, we show how high-dimensional problems could be dealt with by means of Caratheodory plots or how trajectory-based quantum-classical analyses reveal unexpected discrepancies. As a working model, we consider the reaction dynamics associated with a Mueller-Brown potential energy surface, where we focus on the relationship between reaction paths and trajectories as well as on reaction probability calculations from classical and quantum trajectories.

description: Pregnancy is not a disease or illness, but requires clinical surveillance as life-threatening complications can develop. Preeclampsia, one such potentially serious complication, puts both mother and baby at risk. Self-monitoring blood pressure in the general population is well established, and its potential in pregnancy is currently being explored. In the context of self-monitoring, the information and guidance given to women regarding hypertension, and the literature they themselves seek out during pregnancy, are vital to perceptions of disease risk and subsequent responses to, and management of, any symptoms. Drawing on online, offline, official, and unofficial sources of information, discourses are examined to provide analysis of how self-responsibilization is reflected in contemporary information, advice, and guidance drawn from multiple sources. A paradox emerges between the paternalistic and lay discourses that seek to challenge and regain control. Findings are discussed in the context of Foucault’s governmentality and medical power.
Estimating the relative energetic cost of foraging in Pacific Coast Feeding Group grey whales from biologging data
Creators: name: Colson, Kate M.
Publisher: name: University of British Columbia
Year: 2023

description: Biologging tags that record high-resolution tri-axial accelerometry data are proving to be integral to the study of foraging ecology of large, free-roaming marine mammals, such as whales. They have been applied to a number of baleen whale species that feed pelagically through lunges or ram filtration to quantitatively define behaviours and estimate energetic costs. However, few behavioural ecology studies using accelerometry data have been conducted on grey whales, a unique baleen whale that performs benthic suction feeding. Using suction cup tri-axial accelerometer tag deployments on 10 Pacific Coast Feeding Group (PCFG) grey whales along the Oregon and Washington coasts, I defined signals of foraging behaviour at both the broad state (dive) and foraging tactic (roll event) scales. I then estimated the relative energetic cost of these behaviours using energy expenditure proxies derived from the accelerometry data—Overall Dynamic Body Acceleration (ODBA; ms⁻²), stroke rate (Hz), stroke amplitude (radians per s), and duration of dives with different foraging tactics performed (min). Hidden Markov Models (HMMs) defined three biologically distinct states—forage, search, and transit—using turn angle, dive duration, dive tortuosity and presence of roll events. Classification and Regression Tree (CART) models best defined the foraging tactics of headstands, benthic digs, and side swims using median pitch, depth to body length ratio, and absolute value of the median roll. These definitions of grey whale foraging signals using accelerometry data add to the quantitative descriptions of foraging behaviours previously described for baleen whales. Stroke rate identified foraging and headstanding as being the most energetically costly activities at the broad state and foraging tactic scales. These findings contribute to the foundational understanding of grey whale foraging energetics needed to assess the impacts of various conservation concerns on the fitness and interpret patterns of behaviour choice of this unique group of grey whales.

description: In a previous paper, we have proposed the minimal B-L extended standard model as a phenomenologically viable model that realizes the Coleman-Weinberg-type breaking of the electroweak symmetry. Assuming the classical conformal invariance and stability up to the Planck scale, we will show in this paper that the model naturally predicts TeV scale B-L breaking as well as a light standard-model singlet Higgs boson and light right-handed neutrinos around the same energy scale. We also study phenomenology and detectability of the model at the Large Hadron Collider (LHC) and the International Linear Collider (ILC).

description: Metal atoms in solid and liquid helium-4 have attracted some interest either as a way to keep the atoms in a weakly perturbing matrix, or using them as a probe for the helium host medium. Laser sputtering with nanosecond pulsed lasers is the most often used method for atom production, resulting however in a substantial perturbation of the matrix. We show that a much weaker perturbation can be obtained by using femtosecond laser pulses with energy as low as 10 $μ$J. As an unexpected benefit, the atomic density produced is much higher.

description: To increase the size of the flowers for easy plucking, flower yield, pyrethrins content (%), and elite mutant selection in pyrethrum. To increase pyrethrum production and acclimatize in north Indian plain condition, a genetic improvement program was undertaken to widen the range of variations for size and yield of flowers and pyrethrins content (%) in pyrethrum crop. Pyrethrum seeds of the variety Avadh were irradiated with gamma rays at 20 to 300 Gy doses in Gamma chamber 5000 (cobalt-60 research irradiator). Observations gathered visually in M1 based on vigour, synchronization of flowering, and flower’s size. Out of 90 M2 families, 20 mutants were raised in M3 along with the check-in preliminary evaluation trial. The four promising mutants, 1 (20 Gy-3), 7 (40 Gy-5), 10 (40 Gy-8), 14 (60 Gy19-10) was grown for four years in a bench-scale trial (randomized block design, replicated thrice) to test the yield performance and selection of high yielding elite mutant (s). It has been found that pyrethrum is sensitive to gamma rays irradiation and produced a high range of qualitative and quantitative variations. After massive screening over four years, two promising mutants for high dry flower yield and pyrethrins content, namely 7 (40 Gy-5), and 10 (40GY-8) were isolated. The mutagenesis changed traits mean in positive or negative directions. Pyrethrum plant is highly sensitive to gamma irradiation and produced a high range of variability in the qualitative and quantitative traits. The mutagenesis changed the mean of traits in both positive and negative directions. Due to mutagenic efficacy, two mutants 7 (40 Gy-5), and 10 (40GY-8) were expressed high performance for pyrethrin percent i.e. 87.23 and 59.78% improvement over the check variety ‘Avadh’, with synchronous flowering. These two mutants are in the pipeline for release as a variety for cultivation in the North Indian plains.

Phylogenetic methods for estimating human immunodeficiency virus 1 proviral integration dates

Publisher: name: University of British Columbia
Year: 2023

description: Human immunodeficiency virus 1 (HIV) maintains an ongoing pandemic. Despite combined antiretroviral therapies (cART) that can suppress viral load, halt progression to acquired immunodeficiency syndrome, and reduce morbidity, HIV infection has no durable cure. This is due in part to the existence of HIV proviruses that are integrated in CD4+ T cells in a transcriptionally latent state that can persist in the presence of cART. Forming a complete understanding of the dynamics of this “persistent” or “latent” reservoir is important for developing a durable HIV cure. There are some aspects of the persistent reservoir dynamics that are poorly understood, for example the timing of integration and duration of persistence of latent proviruses. In this thesis, I explore and develop different methods based on phylogenetics to estimate integration dates of proviral sequences. I start by describing a simulation of within-host HIV sequence evolution that includes the HIV persistent reservoir. This simulation is used to assess the accuracy of different integration date estimation methods. Next, I describe a method to estimate integration dates using linear regression on a maximum likelihood phylogeny and its web application implementation. I performed the linear regression on four participant data sets to estimate their proviral integration date distributions. These data included sequences that were collected from cells from different CD4+ T cell subsets. Finally, I explore a Bayesian method that uses a package I created for the software BEAST2 to estimate proviral integration dates. I applied this Bayesian method to one simulated data set and two empirical data sets. Overall, I found varied distributions of HIV integration dates among individuals living with HIV. This suggests that HIV cure interventions may benefit from personalized approaches. The simulations found that the method using Bayesian analysis produced the most accurate results. However, this method produced unrealistic results on some empirical data sets unless care was taken in selecting priors. Developing accurate and adaptable methods to understand the HIV persistent reservoir will assist HIV cure research.

description: We have performed electrical resistivity measurements on single crystal BaFe2As2 under high pressure P up to 16 GPa with a cubic anvil apparatus, and up to 3 GPa with a modified Bridgman anvil cell. The samples were obtained from the same batch, which was grown with a self-flux method. A cubic anvil apparatus provides highly hydrostatic pressure, and a modified Bridgman anvil cell, which contains liquid pressure transmitting medium, provides quasi hydrostatic pressure. For highly hydrostatic pressure, the crystal phase and magnetic transition temperature decreases robustly with P and disappears at around 10 GPa. The superconducting phase appears adjacent to magnetic phase in narrow pressure region between 11 and 14 GPa. The tiny difference of hydrostaticity between the cubic anvil apparatus and modified Bridgman anvil cell induces a drastic effect on the phase diagram of BaFe2As2. This result indicates that small uniaxial stress along c-axis strongly suppresses the structural/antiferromagnetic ordering and stabilizes superconductivity at much lower pressure.

description: We present photometry of WASP-10 during the transit of its short-period Jovian planet. We employed the novel PSF-shaping capabilities the OPTIC camera mounted on the UH 2.2m telescope to achieve a photometric precision of 4.7e-4 per 1.3 min sample. With this new light curve, in conjunction with stellar evolutionary models, we improve on existing measurements of the planetary, stellar and orbital parameters. We find a stellar radius Rstar = 0.698 +/- 0.012 Rsun and a planetary radius Rp = 1.080 +/- 0.020 Rjup. The quoted errors do not include any possible systematic errors in the stellar evolutionary models. Our measurement improves the precision of the planet's radius by a factor of 4, and revises the previous estimate downward by 16% (2.5sigma, where sigma is the quadrature sum of the respective confidence limits). Our measured radius of WASP-10b is consistent with previously published theoretical radii for irradiated Jovian planets.

description: X-ray sources with very few counts can be identified with low-noise X-ray detectors such as ACIS onboard the Chandra X-ray Observatory. These sources are often too faint for parametric spectral modeling using well-established methods such as fitting with XSPEC. We discuss the estimation of apparent and intrinsic broad-band X-ray fluxes and soft X-ray absorption from gas along the line of sight to these sources, using nonparametric methods. Apparent flux is estimated from the ratio of the source count rate to the instrumental effective area averaged over the chosen band. Absorption, intrinsic flux, and errors on these quantities are estimated from comparison of source photometric quantities with those of high S/N spectra that were simulated using spectral models characteristic of the class of astrophysical sources under study. The concept of this method is similar to the long-standing use of color-magnitude diagrams in optical and infrared astronomy, with X-ray median energy replacing color index and X-ray source counts replacing magnitude. Our nonparametric method is tested against the apparent spectra of 2000 faint sources in the Chandra observation of the rich young stellar cluster in the M17 HII region. We show that the intrinsic X-ray properties can be determined with little bias and reasonable accuracy using these observable photometric quantities without employing often uncertain and time-consuming methods of non-linear parametric spectral modeling. Our method is calibrated for thermal spectra characteristic of stars in young stellar clusters, but recalibration should be possible for some other classes of faint X-ray sources such as extragalactic AGN.

description: We study some field representations of vector supersymmetry with superspin Y=0 and Y=1/2 and nonvanishing central charges. For Y=0, we present two multiplets composed of four spinor fields, two even and two odd, and we provide a free action for them. The main differences between these two multiplets are the way the central charge operators act and the compatibility with the Majorana reality condition on the spinors. One of the two is related to a previously studied spinning particle model. For Y=1/2, we present a multiplet composed of one even scalar, one odd vector and one even selfdual two-form, which is a truncation of a known representation of the tensor supersymmetry algebra in Euclidean spacetime. We discuss its rotation to Minkowski spacetime and provide a set of dynamical equations for it, which are however not derived from a Lagrangian. We develop a superspace formalism for vector supersymmetry with central charges and we derive our multiplets by superspace techniques. Finally, we discuss some representations with vanishing central charges.

Utilization of discrete fracture networks for kinematic assessment of bench scale failures in an open pit mining environment
Creators: name: King, Matthew N.T.
Publisher: name: University of British Columbia
Year: 2023

description: In hard rock open pit mining environments the stability conditions of the bench are controlled by the structural discontinuities. Kinematic analyses of rigid blocks provide a prediction of the expected breakback following mining activities. In general, the observed breakback is steeper than that predicted using conventional kinematic analysis methods, which are known to have conservative assumptions such as ubiquity and full continuity of structures. However, this cannot be relied upon in all cases (i.e., exploration projects or mining projects not yet into construction) and design optimization or steepening does not occur until backed by empirical evidence. Utilizing a discrete fracture network (DFN) method involving polyhedral kinematics an attempt is made to see if the steeper observed designs can be predicted using structure that is stochastic and discontinuous. DFNs have limitations due to data uncertainty, in particular to the continuity of structures. Sensitivity assessments of the continuity of structures within a DFN are also investigated. Results of the DFN based kinematic analyses indicate steeper expected breakback angles compared to conventional kinematic analyses, however, the DFN results are inconsistent with the observed breakback conditions. Ultimately the DFN models failed to generate sufficient blocks to represent the actual breakback conditions. Future work is required particularly with regard to determining the validity of a DFN. Simple statistical assessments of DFNs only confirm that the DFN adheres to the input parameters such as orientation, continuity, and spacing. An additional check needs to be performed to assess if the spatial locations of the generated structures matches those of the observed structures. Additionally the potential of progressive failure of key blocks at the bench scale requires further analysis to determine its contribution to breakback of benches in a mining environment.

description: Surface acoustic wave (SAW) propagation is a powerful method to investigate 2D electron systems. We show how SAW observables are influenced by coupling to the 2D massless Dirac electrons of graphene and argue that Landau oscillations can be observed as function of gate voltage for constant field. Contrary to other transport measurements, the zero-field SAW propagation gives the wave vector dependence of graphene conductivity for small wave numbers. We predict a crossover from Schroedinger to Dirac like behaviour as a function of gate voltage, with no attenuation in the latter for clean samples.

description: Phased array feeds (PAFs) for reflector antennas offer the potential for increased reflector field of view and faster survey speeds. To address some of the development challenges that remain for scientifically useful PAFs, including calibration and beamforming algorithms, sensitivity optimization, and demonstration of wide field of view imaging, we report experimental results from a 19 element room temperature L-band PAF mounted on the Green Bank 20-Meter Telescope. Formed beams achieved an aperture efficiency of 69% and system noise temperature of 66 K. Radio camera images of several sky regions are presented. We investigate the noise performance and sensitivity of the system as a function of elevation angle with statistically optimal beamforming and demonstrate cancelation of radio frequency interference sources with adaptive spatial filtering.

description: O artigo tem por objetivo contextualizar e debater o processo de formação do conceito de campesinato e sua "transição" para agricultura familiar. As divergências e convergências no debate teórico metodológico e suas implicações para o avanço de consensos em torno da problemática para conceituar e definir o que vem a ser as populações rurais que se organizam em propriedades familiares. Espaço este que não será lugar exclusivo para o mundo trabalho, mas compartilha trabalho e espaço de vida. Como denominá-los? Quais as implicações dessa denominação? Estas são questões que sempre estão na linha do horizonte para quem mergulha no debate sobre o mundo rural e que são fundamentais para pensar o processo de quem são, onde estão, como vivem, o que produzem, quais as condições para sua reprodução social e como se relacionam com as sociedades envolventes. Portanto, este artigo apresenta e problematiza o debate, que não se esgota, sobre até onde é ou não campesinato, agricultura familiar, agricultura familiar camponesa, agricultura familiar moderna, enfim, e quais os pressupostos que fundamentam tais construções conceituais.

description: Bir medeniyetin veya bir milletin zor zamanlarda yok olmadan kurtulmayı başararak ayakta kalabilmesi ve kritik dönüm noktalarında kendini yenileyebilmesi, geleceğe dönük ütopik vizyonlara bağlıdır. Büyük insanların ütopyaları da büyüktür. Realizmin sınırları içinde mahpus kalanların akıl dışı gördüğü bu ütopyalar, kitlelere son derece cazip gelir ve onları ateşleyerek harekete geçirir. Bu tür ütopyalar sosyal ve siyasi değişimin motorudur. Ali Şeriati, Meşhed radyosunda dini programlar yapması istediğinde, bu teklifi ‘Amerikan tarzı İslam’ söylemini beceremeyeceğini söyleyerek kabul etmemiştir. Bununla neyi kastettiği sorulduğunda, sadece ibadet ve merasimlerin ince noktaları ve ayrıntılarıyla ilgilenen İslam’ı kastettiğini söyler ve ilave olarak ‘bu detayları okumuş, ezberlemiş ve öğrencilerime ezberletmiş olmama rağmen bunların içeriğini hiçbir zaman anlayamadım’ dediği rivayet edilir (s. 93). Bu ve benzeri sıra dışı ve aykırı düşüncelerle Ali Şeriati, İran’da devrimle sonuçlanan sürece ciddi katkıda bulunmuştur.
Characterization and exploitation of host factors to modulate HIV-1 latency

description: Despite decades of research, HIV-1 remains an ever-prevalent burden on global human health. For many, antiretroviral therapy (ART) is capable of controlling viral replication. However, ART is not a cure and must be administered life-long with discontinuation resulting in viral rebound. The persistence of HIV-1 is the result of a fraction of provirus establishing latency early upon infection of T cells. This population of transcriptionally silent provirus are undetectable to the immune system, unaffected by ART, and are capable of spurious reactivation and clonal proliferation. It has been hypothesized that latency modulating compounds may produce a sterilizing cure for HIV-1. In this thesis, I identify and characterize transcriptional regulators of HIV-1 and examine the ability of small molecules that target these factors to affect viral latency. RBE3 and RBE1 are two of the most highly conserved cis-elements in the HIV-1 LTR. Binding of these elements by the RBF-2 complex, composed of TFII-I and a USF1/USF2 heterodimer, is essential for reactivation of latent provirus. In my work, TFII-I recruits TRIM24 to the LTR resulting in stimulated transcriptional elongation. Furthermore, inhibition of the TRIM24 bromodomain by IACS-9571 reversed proviral latency, an effect that was associated with increased TRIM24 LTR occupancy and facilitation of RNAPII elongation. Thus, TRIM24 bromodomain inhibitors such as IACS-9571 represent a novel class of HIV-1 LRAs that are of interest to the “shock and kill” strategy of viral elimination. Several LTR bound sequence-specific transcriptional activators are regulated by the Mediator complex kinase, CDK8/19. Here, I show that chemical inhibition of CDK8/19 kinase activity enforces the establishment of HIV-1 latency and hinders viral reactivation in response to latency reversal agents. Similar to kinase inhibition, genetic ablation of CDK8 promoted latency while also suppressing reactivation to several agonists. As such, CDK8/19 kinase activity is an attractive latency promoting target that may contribute to the development of a “block and lock” functional cure. Collectively, in this thesis I have identified novel regulators of proviral expression for which existing drugs can target to either promote or antagonize HIV-1 latency thus exhibiting therapeutic potential.

Review of Flicker Noise Spectroscopy in Electrochemistry

description: This review presents the fundamentals of Flicker-Noise Spectroscopy (FNS), a general phenomenological methodology in which the dynamics and structure of complex systems, characterized by nonlinear interactions, dissipation, and inertia, are analyzed by extracting information from various signals with stochastically varying components generated by the systems. The basic idea of FNS is to treat the correlation links present in sequences of different irregularities, such as spikes, "jumps", and discontinuities in derivatives of different orders, on all levels of the spatiotemporal hierarchy of the system under study as main information carriers. The tools to extract and analyze the information are power spectra and difference moments (structural functions) of various orders. Presently, FNS can be applied to three types of problems: (1) determination of parameters or patterns that characterize the dynamics or structural features of complex systems; (2) finding precursors of abrupt changes in the state of various complex systems based on a priori information about the dynamics of the systems; and (3) determination of flow dynamics in distributed systems based on the analysis of dynamic correlations in stochastic signals that are simultaneously measured at different points in space. Examples of FNS applications to such problems as parameterization of the images produced with atomic force microscopy (AFM), determination of precursors for electric breakdowns and major earthquakes, and analysis of electric potential fluctuations in electromembrane systems, as well as to some other problems in electrochemistry and medicine are discussed.
