description: The field of adult-centric brain magnetic resonance (MR) image analysis is well-established, yet research on the pediatric population remains limited. Pediatric brains undergo rapid development and present complex structural and functional attributes, necessitating a customized approach for MR processing and machine learning (ML) analysis. This study introduces a comprehensive processing framework tailored for pediatric (2 to 8 years old) T1-weighted structural brain MR scans, considering several processing steps including skull stripping (SS), registration, bias correction, normalization, resizing, and tissue segmentation, utilizing neuroimaging tools and Python-based libraries (FSL, Freesurfer, SimpleITK, SciPy, etc.). For SS, FSL-BET and SynthStrip are recommended. For registration, an age-specific template selection is recommended to correlate the characteristics of pediatric brains. Bias correction and normalization are desirable for non-uniform and distinct voxel intensities respectively. Depending on the post-processing requirements, resizing and tissue segmentation can be optional, where FSL-FAST was preferred for segmentation under non-artifact conditions. This study incorporated unexposed controls to develop the framework, while prenatal alcohol exposure (PAE) scans were utilized to validate the generalizability of the framework, confirmed by visual inspection as a qualitative approach. Furthermore, deep learning (DL) is applied by utilizing the pre-trained simple fully convolutional network (SFCN) as a transfer learning (TL) approach for extracting features from the processed scans and a newly trained classifier to distinguish between unexposed and PAE participants. The classifier secured the highest sensitivity of 88.47% with 85.04% average accuracy on testing data when considering a balanced dataset with augmentation for both classes. Moreover, this study performed a preliminary explainability analysis using the Grad-CAM method, highlighting various brain regions including corpus callosum, cerebellum, pons, and white matter (WM) as the most important features in the model’s decision-making process. Despite the challenges of constructing DL models for pediatric populations due to the brain’s rapid development, motion artifacts, and insufficient data, this work highlights the potential of TL where data is limited. Furthermore, this study emphasizes preserving a balanced dataset for fair classification and using explainability to clarify the model’s predictions.

description: The objective of Rethinking International Investment Governance is to change the terms of the debate so that societal values and goals are at the center of discussions about each reform proposal and process. This book rethinks international investment law as a key system in global economic governance that should incorporate principles of transparency, participation, reciprocity, accountability, and subsidiarity. It critically evaluates the current system of investment governance in light of those principles and goals. And finally, it proposes possible reforms—including multilateral ones—that would realign the governance of international investment with 21st century goals including reduction of poverty and inequality, and protection of human dignity, the environment and the planet.
Diffusive spin dynamics in ferromagnetic thin films with a Rashba interaction

description: In a ferromagnetic metal layer, the coupled charge and spin diffusion equations are obtained in the presence of both Rashba spin-orbit interaction and magnetism. The mis-alignment between the magnetization and the non-equilibrium spin density induced by the Rashba field gives rise to Rashba spin torque acting on the ferromagnetic order parameter. In a general form, we find that the Rashba torque consists of both in-plane and out-of-plane components, ie $\bm{T}=T_{\bot}\hat{\bm{y}}\times{\hat{\bm m}}+T_{\parallel}{\hat{\bm m}}\times({\hat{\bm y}}\times{\hat{\bm m}})$. Numerical simulations on a two dimensional nano-wire discuss the impact of diffusion on the Rashba torque, which reveals a large enhancement to the ratio $T_{\parallel}/T_{\bot}$ for thin wires. Our theory provides an explanation to the mechanism that drives the magnetization switching in a single ferromagnet as observed in the recent experiments.

description: In this Letter we theoretically study the possibility of total power absorption of light in a planar grid modelled as an effective sheet with zero optical thickness. The key prerequisite of this effect is the simultaneous presence of both resonant electric and magnetic modes in the structure. We show that the needed level of the magnetic mode is achievable using the effect of substrate-induced bianisotropy which also allows the huge local field enhancement at the same wavelength where the maximal absorption holds.

description: The Lanczos process constructs a sequence of orthonormal vectors v_m spanning a nested sequence of Krylov subspaces generated by a hermitian matrix A and some starting vector b. In this paper we show how to cheaply recover a secondary Lanczos process starting at an arbitrary Lanczos vector v_m. This secondary process is then used to efficiently obtain computable error estimates and error bounds for the Lanczos approximations to the action of a rational matrix function on a vector. This includes, as a special case, the Lanczos approximation to the solution of a linear system Ax = b. Our approach uses the relation between the Lanczos process and quadrature as developed by Golub and Meurant. It is different from methods known so far because of its use of the secondary Lanczos process. With our approach, it is now in particular possible to efficiently obtain {\em upper bounds} for the error in the {\em 2-norm}, provided a lower bound on the smallest eigenvalue of $A$ is known. This holds in particular for a large class of rational matrix functions including best rational approximations to the inverse square root and the sign function. We compare our approach to other existing error estimates and bounds known from the literature and include results of several numerical experiments.

description: Children’s knowledge of number sense is foundational to their learning of more advanced mathematics. However, the specific conceptual and procedural skills that are assumed to comprise number sense are not necessarily the same across the fields of mathematics education and psychology (Osana & Proulx, 2018). The lack of consistency in how number sense is understood may influence the collaborative work between school psychologists and teachers who work collaboratively to support children’s mathematics learning. The goal of this study was to identify how school psychologists’ and teachers’ conceptualizations of number sense compare. To identify number sense conceptualizations, 16 participants (n = 8 school psychologists; n = 8 teachers) were presented with vignettes designed to elicit understandings of number sense based on Whitacre et al.’s (2020) notions of Approximate Number Sense (ANS), Early Number Sense (ENS), and Mature Number Sense (MNS), as well as the four grounding metaphors of arithmetic proposed by Lakoff and Núñez (2000). Questions associated with each vignette were used to prompt participants to share which aspect(s) of number sense they noticed. A template approach to thematic analysis was used to analyze interview transcripts. Overall, both similarities and differences were observed between groups. Teachers attended more often to MNS constructs whereas school psychologists noticed ANS constructs of number sense (specifically, innate nature of number sense) more often than teachers. Professional groups similarly attended to ENS constructs of number sense and to the four grounding metaphors of number. Taken together, this research provides support for the need to increase effort to promote a coherent, unitary understanding of number sense across the fields of school psychology and education to better support inter-professional collaboration in support of children’s mathematics learning.

description: An error analysis of approximation of derivatives of the solution to the Cauchy problem for parabolic equations by finite differences is given taking into account that the solution itself is evaluated using weak-sense numerical integration of the corresponding system of stochastic differential equations together with the Monte Carlo technique. It is shown that finite differences are effective when the method of dependent realizations is exploited in the Monte Carlo simulations. This technique is applicable to evaluation of Greeks. In particular, it turns out that it is possible to evaluate both the option price and deltas by a single simulation run that reduces the computational costs. Results of some numerical experiments are presented.

description: Family history, a well-established risk factor for breast cancer, can have both genetic and environmental contributions. Shared environment in families as well as epigenetic changes that also may be influenced by shared genetics and environment may also explain familial clustering of cancers. Epigenetic regulation, such as DNA methylation, can change the activity of a DNA segment without a change in the sequence; environmental exposures experienced across the life course can induce such changes. However, genetic-epigenetic interactions, detected as methylation quantitative trait loci (mQTLs; a.k.a. meQTLs) and haplotype-dependent allele-specific methylation (hap-ASM), can also contribute to inter-individual differences in DNA methylation patterns. To identify differentially methylated regions (DMRs) associated with breast cancer susceptibility, we examined differences in white blood cell DNA methylation in 29 candidate genes in 426 girls (ages 6-13 years) from the LEGACY Girls Study, 239 with and 187 without a breast cancer family history (BCFH). We measured methylation by targeted massively parallel bisulfite sequencing (bis-seq) and observed BCFH DMRs in two genes: ESR1 (Δ4.9%, P = 0.003) and SEC16B (Δ3.6%, P = 0.026), each of which has been previously implicated in breast cancer susceptibility and pubertal development. These DMRs showed high inter-individual variability in methylation, suggesting the presence of mQTLs/hap-ASM. Using single nucleotide polymorphisms data in the bis-seq amplicon, we found strong hap-ASM in SEC16B (with allele specific-differences ranging from 42% to 74%). These findings suggest that differential methylation in genes relevant to breast cancer susceptibility may be present early in life, and that inherited genetic factors underlie some of these epigenetic differences.

description: We report a finite temperature micromagnetic method (FTM) that allows for the calculation of the coercive field of arbitrary shaped magnetic nanostructures at time scales of nanoseconds to years. Instead of directly solving the Landau-Lifshitz-Gilbert equation, the coercive field is obtained without any free parameter by solving a non linear equation, which arises from the transition state theory. The method is applicable to magnetic structures where coercivity is determined by one thermally activated reversal or nucleation process. The method shows excellent agreement with experimentally obtained coercive fields of magnetic nanostructures and provides a deeper understanding of the mechanism of coercivity.

description: Biotechnology governance has garnered significant attention in the last decade. One notable example is the use of genetically modified mosquitoes (GMMs) to control vector-borne diseases (VBDs) such as malaria and dengue fever. While promising, GMMs are controversial. Some scientists and public health agencies support GMMs, however not all groups welcome biotechnology as a disease control measure. To date, most field trials have been met with controversial reception. While extensive literature addresses GMM governance, gaps remain including attention to geographical scale and scientific experts’ perspectives on engagement in governance processes. Considering these gaps, the objective of this thesis is to examine academic debates in GMM governance. Using methods such as a scoping review, and semi-structured qualitative interviews (n = 14), this thesis asks two interrelated questions. Drawing on critical geographies of scale, the first question asks: How is scale represented in the academic literature on GMM governance, and what power dynamics do representations of scale uphold or challenge? Drawing on theories of public engagement in science and technology studies (STS), the second question asks: What perspectives do scientific experts hold regarding public engagement for GMMs? First, key findings reveal that in the academic literature, GMM governance is largely framed through global/local scalar binaries which run the risk of perpetuating historical inequalities between regions and groups in ways that limit the potential for democratic engagement. Second, key findings spotlight how the values and visions of scientific experts, who are at the forefront of GMM development, play a central role in how public engagement unfolds. While participants valued the principle of engagement as an integral part of ethical research, most did not consider integrating engagement into research agenda-setting processes beyond GMM field trials. A critical geography lens provides an opportunity to examine how ideas and values around GMMs are embedded in sociocultural contexts. This research is timely given that these applications are in the early stages of development and oversight frameworks are evolving.

description: We consider the coherent control of a quantum bit by the use of short pulses with finite duration τ_p. By shaping the pulse, we perturbatively decouple the dynamics of the bath from the dynamics of the quantum bit during the pulse. Such shaped pulses provide single quantum bit gates robust against decoherence which are useful for quantum information processing. We extend previous results in two ways: (i) we treat frequency modulated pulses and (ii) we pass from time-independent baths to analytically time-dependent baths. First and second order solutions for π- and π/2-pulses are presented. They are useful in experiments where amplitude modulation is difficult to realize.

description: Background: Rhinitis and conjunctivitis are often linked to asthma development through an allergic pathway. However, runny nose and watery eyes can result from nonallergic mechanisms. These mechanisms can also underlie exercise-induced wheeze (EIW), which has been associated with urgent medical visits for asthma, independent of other indicators of asthma severity or control.
Objective:
To test the hypothesis that rhinitis or watery eyes without cold symptoms (RWWC) in infancy predict development of EIW and urgent respiratory-related medical visits at school age, independent of seroatopy.
Methods:
Within a prospective birth cohort of low-income, urban children (n = 332), RWWC was queried during the first year of life. Relative risks (RRs) for EIW, emergency department (ED) visits, and hospitalizations for asthma and other breathing difficulties at 5 to 7 years of age were estimated with multivariable models. Seroatopy was determined at 7 years of age.
Results:
Infant RWWC was common (49% of children) and predicted school-age EIW (RR, 2.8; P

description: Given a non-rational real space curve and a tolerance $ε>0$, we present an algorithm to approximately parametrize the curve. The algorithm checks whether a planar projection of the space curve is $ε$-rational and, in the affirmative case, generates a planar parametrization that is lifted to an space parametrization. This output rational space curve is of the same degree as the input curve, both have the same structure at infinity, and the Hausdorff distance between them is always finite.
MIL-100(Fe)-Based Composites for Photocatalytic Dye Degradation: Harnessing UV and Visible Light with Enhanced Performance

description: This study explores the photocatalytic degradation efficiencies MIL-100(Fe)-Based composites under both UV and visible light. The synthesized ZnO/MIL-100(Fe), ZnO/Ni@MIL photocatalysts were assessed based on their ability to degrade Rhodamine 6G (R6G), a cationic dye. The main aim of integrating MIL-100(Fe) into ZnO nanoparticles is to enhance the surface area of the photocatalyst to improve adsorption and photocatalytic performance, which is crucial for effective dye degradation. Under UV light, ZnO/MIL-100(Fe) exhibited the highest degradation efficiency, achieving complete degradation within 60 minutes. This exceptional performance is attributed to the enhanced adsorption and charge separation and transfer between ZnO and MIL-100(Fe). ZnO/Ni@MIL-100(Fe) followed closely with a 96% degradation efficiency, highlighting the role of Ni nanoparticles in enhancing photocatalytic performance through improved adsorption kinetics and charge carrier dynamics. Under visible light, ZnO/Ni@MIL-100(Fe) demonstrated the highest efficiency, reaching nearly 98% degradation within 60 minutes following by ZnO/MIL-100(Fe) with 88% degradation efficiency. This superior performance is due to the synergistic effects of enhanced light absorption and electron scavenging of Ni nanoparticles. Both synthesized composites exhibit significantly higher efficiency compared to ZnO NPs, MIL-100(Fe), and Ni@MIL-100(Fe). The findings suggest that ZnO/Ni@MIL-100(Fe) is a highly effective photocatalyst under visible light, while ZnO/MIL-100(Fe) excels under UV light. This study underscores the potential of these composites for practical applications in environmental remediation, driven by their enhanced photocatalytic activities and adsorption properties, primarily due to the increased surface area provided by MOFs.
Language minority students with poor and good reading comprehension : reading-related processes and use of reading strategies
Creators: name: Mazabel Ortega, Silvia
Publisher: name: University of British Columbia
Year: 2012

description: Few studies have focused on the comprehension performance of language minority (LM) students and their findings are mixed. Some studies show that reading comprehension is an area of weakness and academic difficulty for LM students whereas others show the language status does not make a difference in reading comprehension performance. Various sources of difficulty LM students experience in reading comprehension have been described. The primary purpose of this study was to examine the similarities and differences between LM good and poor reading comprehenders in terms of their reading-related linguistic and cognitive skills, and their use of reading strategies. A descriptive multiple-case study comparing three poor reading comprehenders to six good reading comprehenders attending grade 6 and matched by gender, age, school, years of schooling in English, and years living in Canada was conducted. Comparisons were made in relation to their language proficiency, word-level reading skills, verbal working memory, and their use of reading strategies. The results indicated that the LM poor reading comprehenders obtained lower scores in measures of morphological awareness skills, word reading accuracy and efficiency, and vocabulary when compared to the good comprehenders. No differing patterns were found for non-word reading skills, syntactic awareness and working memory. As for the use of reading strategies, the poor and good comprehenders used reading strategies before, during and after a reading activity. The good reading comprehenders tended to use global reading strategies more frequently whereas the poor reading comprehenders tended to use support reading strategies more often. No difference was found between the poor and good comprehenders in the use of problem solving reading strategies. Having an explicit goal to perform after reading did not help the overall reading comprehension performance of participants but it promoted their use of reading strategies. Weaknesses in reading basic skills and higher-order skills seem to be sources of difficulty related to the reading comprehension failures of LM struggling comprehenders in this study. Future research should examine whether and how the direct teaching of morphological skills and strategic reading could help the reading comprehension performance of LM students.

description: The $5 - 20 M_\odot$ dark objects in X-ray binary systems and the $10^5 - 10^9 M_\odot$ dark objects in galactic nuclei are currently thought to be the Kerr black holes predicted by General Relativity. However, direct observational evidence for this identification is still elusive, and the only viable approach to confirm the Kerr black hole hypothesis is to explore and rule out any other possibility. Here we investigate the final stages of the accretion process onto generic compact objects. While for Kerr black holes and for more oblate bodies the accreting gas reaches the innermost stable circular orbit (ISCO) and plunges into the compact object, we find that for more prolate bodies several scenarios are possible, depending on the spacetime geometry. In particular, we find examples in which the gas reaches the ISCO, but then gets trapped between the ISCO and the compact object. In this situation, accretion onto the compact object is possible only if the gas loses additional angular momentum, forming torus-like structures inside the ISCO.

description: Rivers support diverse and dynamic ecosystems worldwide, offering significant societal and economic benefits. However, infrastructure development threatens the ecosystem processes, biodiversity, and services these rivers provide. A new approach that helps maintain the water flow on our planet and restores what was harmed is needed. Urban planners and designers can play a major role in this shift since most harmful human interventions are in our cities. This dissertation follows a practice-based design science research methodology to design a toolkit to be used by urban designers for river interventions, proposing and testing an “Intersectional” design approach as a tool to allow for hearing the hidden voices about how the river is being conceived and bring these voices on board. Beginning with defining the related contexts and affected groups, besides studying similar precedents, the toolkit progresses via a series of analytical tools that illustrate an emergent framework for the ‘the Barada River design exploration exercise’: the re-conceptualization of the Barada River in Damascus as a green integrative spine, an ‘urban living room’ that re-connects the city with its surrounding natural environment, and a catalyst for ecological urban regeneration. Each tool is developed to serve a certain purpose and to allow progression to the subsequent step using the next tool. Then, it integrates all the tools to offer the DAISA toolkit as an answer to the research question. The presented work on the Barada River case can be considered an example of how the toolkit can be used. However, the DAISA toolkit is designed to be flexible and easily modified to tackle other similar case studies.

description: We present the Strong Lensing Legacy Survey - ARCS (SARCS) sample compiled from the final T0006 data release of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) covering a total non-overlapping area of 159 sq.deg. We adopt a semi-automatic method to find gravitational arcs in the survey that makes use of an arc-finding algorithm. The candidate list is pruned by visual inspection and ranking to form the SARCS sample. This list also includes some serendipitously discovered lens candidates. The SARCS sample consists of 127 lens candidates which span arc radii~2"-18" within the unmasked area of ~ 150 sq. deg. Within the sample, 54 systems are promising lenses amongst which, we find 12 giant arcs and 2 radial arc candidates. From our sample, we detect a systematic alignment of giant arcs with the ellipticity of the baryonic component of the lens in concordance with previous studies. The lens redshift distribution corresponding to both the giant arcs and all arcs, estimated from photometric catalogs, peaks at z~0.6. Owing to the large area and depth of the CFHTLS, we find the largest lens sample probing group-scales for the first time. We compare the observed image separation distribution (ISD) of our arcs with theoretical models. A two-component density profile for the lenses which accounts for both the central galaxy and dark matter component is required by the data to explain the observed ISD. Unfortunately, current levels of uncertainties and degeneracies accommodate models both with and without adiabatic contraction. We also show the effects of changing parameters of the model that predict the ISD and that a larger lens sample might constrain relations such as the concentration-mass relation, mass-luminosity relation and slope of the luminosity function.

Respiratory infections--Prevention
Pediatrics

description: In sickle cell disease, respiratory infection and asthma may lead to respiratory complications that are a leading cause of morbidity and mortality. Vitamin D has anti-infective and immunomodulatory effects that may decrease the risk for respiratory infections, asthma, and acute chest syndrome. We conducted a randomized double-blind active-controlled clinical trial to determine whether monthly oral vitamin D3 can reduce the rate of respiratory events in children with sickle cell disease. Seventy sickle cell subjects, ages 3-20 years, with baseline records of respiratory events over 1 year before randomization, underwent screening. Sixty-two subjects with 25-hydroxyvitamin D levels of 5-60 ng/mL were randomly assigned to oral vitamin D3 (100 000 IU or 12 000 IU, n = 31 each) under observed administration once monthly for 2 years. The primary outcome was the annual rate of respiratory events (respiratory infection, asthma exacerbation, or acute chest syndrome) ascertained by the use of a validated questionnaire administered biweekly. Analysis included 62 children (mean age of 9.9 years, 52% female, and predominantly with homozygous HbS disease [87%]) with mean baseline 25-hydroxyvitamin D of 14.3 ng/mL. The annual rates of respiratory events at baseline and intervention years 1 and 2 were 4.34 ± 0.35, 4.28 ± 0.36, and 1.49 ± 0.37 (high dose) and 3.91 ± 0.35, 3.34 ± 0.37, and 1.54 ± 0.37 (standard dose), respectively. In pediatric patients with sickle cell disease, 2-year monthly oral vitamin D3 was associated with a >50% reduction in the rate of respiratory illness during the second year (P = .0005), with similar decreases associated with high- and standard-dose treatment.

description: This study delves into integrating Indigenous cultural values, traditional healing practices, and sustainable architecture to create a comprehensive framework for fostering healing, reconciliation, and empowerment among homeless and vulnerable Indigenous populations in Calgary, Canada. The study adopts a collaborative approach, seeking the wisdom of Indigenous Elders and engaging with members of Siksika Housing to address housing challenges, addiction recovery, and health and emotional well-being. Central to this effort is the development of five Indigenous healing principles derived from Indigenous knowledge and health practices, that serve as design guidelines for Architects and developers for creating an Indigenous Healing Center for Indigenous peoples known as the HT-CIC principles: a holistic approach to healing, traditional healing ways, community relations, Indigenous Ceremonies, and Connection to land. These principles would guide designers to create Healing Centers rooted in Indigenous healing values. The HT-CIC principles are pillars upon which Indigenous Healing and wellness are built, offering pathways toward healing, resilience, and cultural renewal. By embracing these principles, individuals and communities can reclaim their inherent strengths, honor their cultural heritage, and embark on journeys of healing and reconciliation. The study aims not only to alleviate homelessness but also to empower individuals, fostering a holistic journey towards wellness, and self-discovery while promoting Indigenous values within a sustainable built environment.

Changes in Student Well-Being during the First School Year of the COVID-19 Pandemic: Impacts of School Closures and Learning Modality
Creators: name: Anhorn, Ciana Brynn

Subjects: subject: Educational Psychology

description: The COVID-19 pandemic significantly disrupted adolescents’ physical, social, and academic lives. Due to this, how adolescents’ well-being was impacted during the COVID-19 pandemic has been a top priority within research, but results produced have been inconsistent regarding the types of symptoms experienced and the severity. Therefore, the current study aims to answer how adolescent well-being (behavioural concerns and adaptive functioning) was impacted during the first school year of the COVID-19 pandemic, specifically during periods of school closures and in relation to learning modality. The current study used a longitudinal dataset from Alberta, Canada of participants aged 12 to 18, N = 911. At four timepoints between September 2020 and June 2021, students reported information on demographics and learning modality (in-person, virtual, and hybrid). Additionally, youth completed the Behaviour Intervention Monitoring Assessment System (BIMAS-2), a measure of behavioural concerns (negative affect, cognition/attention concerns, conduct behaviours) and adaptive functioning (social and academic functioning). Using LGM and RM MANCOVA/ANCOVA analyses, results indicated that from September 2020 to June 2021 negative affect and cognition/attention concerns increased, albeit scores continued to fall into a non-clinical range. Females endorsed higher rates of all behavioural concerns, and poorer social functioning. Further, students whose parents completed higher levels of education endorsed higher adaptive functioning. School closures had minimal impacts to well-being. Finally, learning modality was not associated with changes in behavioural concerns but receiving in-person education had some effects on social functioning and academic achievement. These results indicate that while there were some decreases in well-being, overall, youth were resilient. This information may be relevant to apply to short-term periods of online/hybrid learning and to use in cases where school closures are required.
Diffusion in sparse networks: linear to semi-linear crossover

description: We consider random networks whose dynamics is described by a rate equation, with transition rates $w_{nm}$ that form a symmetric matrix. The long time evolution of the system is characterized by a diffusion coefficient $D$. In one dimension it is well known that $D$ can display an abrupt percolation-like transition from diffusion ($D>0$) to sub-diffusion (D=0). A question arises whether such a transition happens in higher dimensions. Numerically $D$ can be evaluated using a resistor network calculation, or optionally it can be deduced from the spectral properties of the system. Contrary to a recent expectation that is based on a renormalization-group analysis, we deduce that $D$ is finite; suggest an "effective-range-hopping" procedure to evaluate it; and contrast the results with the linear estimate. The same approach is useful for the analysis of networks that are described by quasi-one-dimensional sparse banded matrices.
