description: Non-dominant multilingual learners, particularly those who have experienced forced displacement, are often met by educational environments where deficit discourses, monolingual norms and colonial silencing persist. This work examines how co-learners from refugee backgrounds in a multiyear land-based program, Soil Camp, have co-created spaces to challenge dominant norms, power dynamics and colonial histories. Alongside racialized facilitators, the children co-constructed environments that affirmed their multilingual identities and empowered agency within the teaching and learning spaces—a significant shift away from monolingual norms seen in formal schooling and dominant societal settings. Based on video-based interaction analyses, the findings illustrate the transformative power of translanguaging practices that validate multilingual identities and intergenerational knowledge systems, resulting in the co-creation of new social realities for learning, exhibited in moment-to-moment interactions. This work on earth-centered translanguaging practice seeks to connect to silenced intergenerational and new knowledge beyond named languages while attending to historicity and power, transcending human and more-than-human (MTH) divides. Children provided glimpses of their semiotic repertoires through highlighted child-led moments, which foraged new pathways for embodied representations of community, identity and MTH (re)connection. The result is translanguaging spaces where linguistic fluidity and embodied communicative practices sustain (re)connection on and with the land.

description: Background:
Hepatitis B is a viral infection that affects the liver and causes both acute and chronic diseases. It spreads through contact with the blood or other body fluids of an infected person. The best way to prevent hepatitis B is to get vaccinated. Treatment options for chronic hepatitis B include antiviral medications and liver transplantation. Hepatitis B virus can easily pass from a pregnant woman with hepatitis B to her baby at birth. In the Forcibly Displaced Myanmar National's camp, Hepatitis B is affecting more and more mothers and children day by day at an alarming rate.
Objective:
This study aimed to find out the prevalence of Hepatitis B among the pregnant women of Forcibly Displaced Myanmar National people.
Methods:
This was a cross-sectional study conducted on pregnant women who have visited OPD of Maternal and Child Health Care Centre by Human Aid Bangladesh in Balukhali camp 9, Ukhiya, Cox's Bazar. A total of 465 subjects were included in the study. The respondents were interviewed and information was recorded in the questionnaire. The laboratory investigation was done and collected from the patient on spot from the facility. Ethical issues were maintained and the results were obtained to complete the data sheet analyzed by SPSS, Z test, t-test, Chi-Square test.
Results:
A total of 465 respondents were interviewed and tested for hepatitis B infection by HbsAg strip test by ICT method. In the study 53(11.40%) of the respondents were found positive for hepatitis B infection. Most of the respondents were illiterate 153(32.90%). The maximum respondents were in the age range of 16-20 years(61.94%). Very few respondents were known for hepatitis B infection. 24(5.1%) . Among the respondents, 21(4.52%) had a positive partner or family member. Most of the respondents 368(79.14)were not vaccinated.
Conclusion:
The prevalence of Hepatitis B Infection among Pregnant women of Forcibly Displaced Myanmar National is quite high. Lack of knowledge, poverty, lack of vaccination, and violence contributed behind the high rate of Hepatitis B Infection among them.

Self-contained two-layer shallow water theory of strong internal bores

description: We show that interfacial gravity waves comprising strong hydraulic jumps (bores) can be described by a two-layer hydrostatic shallow-water (SW) approximation without invoking additional front conditions. The theory is based on a new SW momentum equation which is derived in locally conservative form containing a free parameter $α.$ This parameter, which defines the relative contribution of each layer to the pressure at the interface, affects only hydraulic jumps but not continuous waves. The Rankine-Hugoniot jump conditions for the momentum and mass conservation equations are found to be mathematically equivalent to the classical front conditions, which were previously thought to be outside the scope of SW approximation. Dimensional arguments suggest that $α$ depends on the density ratio. For nearly equal densities, both layers are expected to affect interfacial pressure with approximately equal weight coefficients, which corresponds to $α\approx0.$ The front propagation velocity for $α=0$ agrees well with experimental and numerical results in a wide range of bore strengths. A remarkably better agreement with high-accuracy numerical results is achieved by $α=\sqrt{5}-2,$ which yields the largest height that a stable gravity current can have.

description: This study examines the complexities of community planning and the significant role of human emotion in the process. Using a practice-based approach, the study explored an innovative codesign strategy as implemented in the Local Area Planning Program (LAP) of The City of Calgary to address these challenges. The LAPs embody a community-led approach to policy and growth planning in established areas, prioritizing emotional co-authorship and the integration of community-specific knowledge in planning. Using a series of semi-structured interviews, six distinguished practitioners provided their diverse perspectives and approaches, with the goal of generating new considerations, tools, and recommendations to integrate into my practice. Applying the LAPs as working models of community connection, this study employed a design science methodology to collect information, reflect, and obtain expert feedback on both practice and design. The aim was to curate a contemporary collection of practice-based tools, strategies, and insights that contribute to The Handbook for Community Connection, a practitioner's guide for fostering emotional connections between communities and the redevelopment process. The Handbook offers a range of practical tools that can fit into a variety of contexts, scales, and available resources, enabling a redefinition of planning processes. The study concludes that by prioritizing empathy and building relationships, redefining planning processes becomes more habitual in practice. Furthermore, continually reflecting on your practice is key to facilitating meaningful connections within community. Relying solely on policy to address societal issues yields limited results; the profession needs a more nuanced and holistic approach. Ultimately, with the study in mind, community planning can be an act of of caring, one that helps to build stronger, more connected, and loving communities.

description: Microarchitectural side channels expose unprotected software to information leakage attacks where a software adversary is able to track runtime behavior of a benign process and steal secrets such as cryptographic keys. As suggested by incremental software patches for the RSA algorithm against variants of side-channel attacks within different versions of cryptographic libraries, protecting security-critical algorithms against side channels is an intricate task. Software protections avoid leakages by operating in constant time with a uniform resource usage pattern independent of the processed secret. In this respect, automated testing and verification of software binaries for leakage-free behavior is of importance, particularly when the source code is not available. In this work, we propose a novel technique based on Dynamic Binary Instrumentation and Mutual Information Analysis to efficiently locate and quantify memory based and control-flow based microarchitectural leakages. We develop a software framework named \tool~for side-channel analysis of binaries which can be extended to support new classes of leakage. For the first time, by utilizing \tool, we perform rigorous leakage analysis of two widely-used closed-source cryptographic libraries: \emph{Intel IPP} and \emph{Microsoft CNG}. We analyze $15$ different cryptographic implementations consisting of $112$ million instructions in about $105$ minutes of CPU time. By locating previously unknown leakages in hardened implementations, our results suggest that \tool~can efficiently find microarchitectural leakages in software binaries.

description: N = 2 Supersymmetric extensions of Galilean conformal algebra (GCA), specified by spin \ell and dimension of space d, are investigated. Duval and Horvathy showed that the \ell = 1/2 GCA has two types of supersymmetric extensions, called standard and exotic. Recently, Masterov intorduced a centerless super-GCA for arbitrary \ell wchich corresponds to the standard extension. We show that the Masterov's super-GCA has two types of central extensions depending on the parity of 2\ell. We then introduced a novel super-GCA for arbitrary \ell corresponding to the exotic extension. It is shown that the exotic superalgebra also has two types of central extensions depending on the parity of 2\ell. Furthermore, we give a realization of the standard and exotic super-GCA's in terms of their subalgebras. Finally, we present a N = 1 supersmmetric extension of GCA with central extensions.

Characteristics of Topside Equatorial Ionospheric Irregularities: An Investigation Using Swarm Echo Measurements
Creators: name: Mohandesi, Ali
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Physics

description: Ionospheric irregularities are a significant source of error in GNSS positioning and navigation as they cause scintillations in trans-ionospheric signals. The elliptical orbit and the high-rate GPS and in-situ irregularity measurements of the Swarm Echo satellite provide a unique opportunity to examine characteristics and distribution of scintillation-causing irregularities. To obtain the results presented in this research, the satellite was re-oriented in 293 sets of novel experiments to make the GAP-O antenna point in the zenith direction. The surface current measurements of the IRM instrument were employed as a measure for in-situ irregularities. In the present thesis, I carried out three studies to investigate distribution, morphology, and scintillation impacts of irregularities that form in the equatorial topside ionosphere during post-sunset hours. The results of the first study show that large-scale ionospheric structures (larger than 80 km) form predominantly below 500 km between 18 and 21 MLT, whereas small-scale irregularities (as small as 160 m) occur at all examined altitudes (330-1280 km) and post-sunset hours (18-24 MLT). The second study presents a novel approach to generate regional maps of small-scale scintillation-producing irregularities using single-satellite observations. I demonstrate that these maps, which are produced using different ionospheric GPS indices, including S4, TEC, and ROTI, can determine the horizontal geo-locations of small-scale irregularities, albeit with large uncertainties in the cross-track direction. The third study presents the spectral characteristics of simultaneous in-situ irregularities and GPS signal intensities. The PSDs of in-situ irregularities show one-component power law behavior, with the most common irregularity spectral index values between 1 and 2. The spectral index for stronger irregularities approaches 1.7. The GPS signal intensity PSDs also obey a power law, with spectral index values within the range of 1.8 and 2.2. Furthermore, the roll-off frequencies obtained from the intensity PSDs are between 0.4 and 2.5 Hz, Which is considerably higher than Fresnel frequencies estimated from ground-based GPS measurements at low latitudes, which fall between 0.2 and 0.45 Hz.

description: Equation of state for systems with particles self-assembling into aggregates is derived within a mesoscopic theory combining density functional and field-theoretic approaches. We focus on the effect of mesoscopic fluctuations in the disordered phase. The pressure -- volume fraction isotherms are calculated explicitly for two forms of the short-range attraction long-range repulsion potential. Mesoscopic fluctuations lead to an increased pressure in each case, except for very small volume fractions. When large clusters are formed, the mechanical instability of the system is present at much higher temperature than found in mean-field approximation. In this case phase separation competes with the formation of periodic phases (colloidal crystals). In the case of small clusters, no mechanical instability associated with separation into dilute and dense phases appears.

description: The effects of synthetic jet actuation on the Kármán vortex formation in the three-dimensional turbulent wake of a cantilevered triangular prism of aspect ratio 4 protruding a thin turbulent boundary layer is investigated experimentally at a Reynolds number of 12000. Results are reported for surface pressure measurement on the leeward face and wake of the obstacle and particle image velocimetry for selected planes in the wake. Synthetic jet is used to excite the flow through two slits spanning the obstacle height along the edges of the leeward face. The mean-field characteristics for the baseflow and actuated flows are characterized and the coherent structures of the flow are identified. It is found that the actuation generally increases the total kinetic energy of turbulent fluctuations (TKE) and the amplitude of the fluctuations due to Kármán shedding. It is shown that the process of vortex formation for the baseflow and actuated flows is qualitatively similar and the cause of shedding frequency shift due to actuation is explained. A self-regulating mechanism is identified in the wake which links the circulation flux in the wake to the streamline curvature and the base pressure. Flow recirculation is shown to have a key role in explaining the wake response to the actuation. It accounts for the increased transfer rate of circulation downstream of the bluff body and affects the base pressure. Forming vortices are observed to reach a saturation level before the shedding in a behavior similar to formation process of vortex rings and vortex lines. A non-dimensional parameter including the effective formation parameters at the moment of shedding is introduced. Similarities between the results observed for the wake of the triangular prism and other geometries suggest a broader relevance of the argument.

description: We construct a theory of holant clones to capture the notion of expressibility in the holant framework. Their role is analogous to the role played by functional clones in the study of weighted counting Constraint Satisfaction Problems. We explore the landscape of conservative holant clones and determine the situations in which a set $\mathcal{F}$ of functions is "universal in the conservative case", which means that all functions are contained in the holant clone generated by $\mathcal{F}$ together with all unary functions. When $\mathcal{F}$ is not universal in the conservative case, we give concise generating sets for the clone. We demonstrate the usefulness of the holant clone theory by using it to give a complete complexity-theory classification for the problem of approximating the solution to conservative holant problems. We show that approximation is intractable exactly when $\mathcal{F}$ is universal in the conservative case.

description: In this paper we consider a class of exactly solvable closed string flux backgrounds that exhibit non-commutativity in the closed string coordinates. They are realized in terms of freely-acting asymmetric Z_N-orbifolds, which are themselves close relatives of twisted torus fibrations with elliptic Z_N-monodromy (elliptic T-folds). We explicitly construct the modular invariant partition function of the models and derive the non-commutative algebra in the string coordinates, which is exact to all orders in α'. Finally, we relate these asymmetric orbifold spaces to inherently stringy Scherk-Schwarz backgrounds and non-geometric fluxes.

description: Conjecturally, the Galois representations that are attached to essentially selfdual regular algebraic cuspidal automorphic representations are Zariski-dense in a polarized Galois deformation ring. We prove new results in this direction in the context of automorphic forms on definite unitary groups over totally real fields. This generalizes the infinite fern argument of Gouvea-Mazur and Chenevier, and relies on the construction of non-classical $p$-adic automorphic forms, and the computation of the tangent space of the space of trianguline Galois representations. This boils down to a surprising statement about the linear envelope of intersections of Borel subalgebras.

description: The learning and usage of an API is supported by documentation. Like source code, API documentation is itself a software product. Several research results show that bad design in API documentation can make the reuse of API features difficult. Indeed, similar to code smells, poorly designed API documentation can also exhibit 'smells'. Such documentation smells can be described as bad documentation styles that do not necessarily produce incorrect documentation but make the documentation difficult to understand and use. This thesis aims to enhance API documentation usability by addressing such documentation smells in three phases. In the first phase, we developed a catalog of five API documentation smells consulting literature on API documentation issues and online developer discussion. We validated their presence in the real world by creating a benchmark of 1K official Java API documentation units and conducting a survey of 21 developers. The developers confirmed that these smells hinder their productivity and called for automatic detection and fixing. In the second phase, we developed machine-learning models to detect the smells using the 1K benchmark, however, they performed poorly when evaluated on larger and more diverse documentation sources. We explored more advanced models; employed re-training and hyperparameter tuning to further improve the performance. Our best-performing model, RoBERTa, achieved F1-scores of 0.71-0.93 in detecting different smells. In the third phase, we first focused on evaluating the feasibility and impact of fixing various smells in the eyes of practitioners. Through a second survey of 30 practitioners, we found that fixing the lazy smell was perceived as the most feasible and impactful. However, there was no universal consensus on whether and how other smells can/should be fixed. Finally, we proposed a two-stage pipeline for fixing lazy documentation, involving additional textual description and documentation-specific code example generation. Our approach utilized a large language model, GPT- 3, to generate enhanced documentation based on non-lazy examples and to produce code examples. The generated code examples were refined iteratively until they were error-free. Our technique demonstrated a high success rate with a significant number of lazy documentation instances being fixed and error-free code examples being generated.

description: In 2021, the Anthologie de la poésie actuelle des femmes au Québec (2021) confirms a hovering intuition: women's poetry is experiencing a meteoric rise in Quebec (Bell and Cormier-Larose, 7). Moreover, as the Gaspar report demonstrates, contemporary women’s poetry rapidly diversifies and includes a plurality of voices (Bell & Cormier- Larose, 2021, 12-13). Among these voices is that of Chloé Savoie-Bernard, who, in her first three collections of poetry, puts forward rebellious, sovereign, and militant female and feminist figures. While, according to Marie-Andrée Bergeron, Chloé Savoie-Bernard is "already one of the most remarkable feminist literary voices of her generation", current scientific research is limited due to the contemporary nature of the work (2019, 38). This thesis therefore focuses on the first three collections of poetry by the Québécois author: Royaume scotch tape (2015), Fastes (2018) and Sainte Chloé de l'amour (2021). The poet brings forth female and feminist figures who embody the spirit of the feminist killjoy as theorized by Sara Ahmed in Living a Feminist Life (2017). The study, divided into three chapters corresponding to the three collections, highlights the particularities of female and feminist figures (often killjoys) through time. They first deconstruct the (fairy)tales that shape and assert identity from childhood while questioning the legacies and heritage they inherit, whether it is that of family, literature, or feminism. Then, they highlight the violence of a patriarchal, heteronormative, and oppressive society that shapes their relationship to their body. They go so far as to use the metaphor of cannibalism to think of the male gaze. They are even killjoys in feminist circles, denouncing “woke-washing” and tokenism. Finally, sisterhood appears as an ideal towards which the author tends, in each collection, as feminist killjoys struggle individually and side-by-side.

description: In this paper, we present a model in which an up-type vector-like quark (VLQ) is charged under a new $U(1)_d$ gauge force which kinetically mixes with the SM hypercharge. The gauge boson of the $U(1)_d$ is the dark photon, $γ_d$. Traditional searches for VLQs rely on decays into Standard Model electroweak bosons $W,Z$ or Higgs. However, since no evidence for VLQs has been found at the Large Hadron Collider (LHC), it is imperative to search for other novel signatures of VLQs beyond their traditional decays. As we will show, if the dark photon is much less massive than the Standard Model electroweak sector, $M_{γ_d}\ll M_Z$, for the large majority of the allowed parameter space the VLQ predominately decays into the dark photon and the dark Higgs that breaks the $U(1)_d$ . That is, this VLQ is a `maverick top partner' with nontraditional decays. One of the appeals of this scenario is that pair production of the VLQ at the LHC occurs through the strong force and the rate is determined by the gauge structure. Hence, the production of the dark photon at the LHC only depends on the strong force and is largely independent of the small kinetic mixing with hypercharge. This scenario provides a robust framework to search for a light dark sector via searches for heavy colored particles at the LHC.

Mercury stabilization using thiosulfate and thioselenate
Creators: name: Ullah, Mohammad Barkat

description: Mercury is commonly present with gold in nature. As a result it has a tendency to follow gold through the cyanide recovery circuit and ends up in the electro-winning cell as elemental mercury. The laws on the sale and international transport of this mercury are changing. Ultimately, it appears that it will be necessary to stabilize and dispose in a stable form. Mercury sulfide (HgS) and mercury selenide (HgSe) have significantly lower solubilities. The concept of using a thiosulfate dissolution/precipitation method to stabilize mercury as mercury sulfide has been investigated. Comparing the solubilities of mercury sulfide and mercury selenide, mercury selenide is much less soluble. For this reason, the second idea in this thesis is to use sodium thioselenate as a source of selenium in mercury solution to produce mercury selenide. To pursue this project, mercury analysis, mercury leaching and mercury precipitation tests were performed at different temperatures and solution conditions. The resulting solutions were analyzed by Atomic Absorption Spectroscopy (AAS) and the solid precipitates were analyzed by X-ray Diffraction. The EDTA titration method for mercury analysis is effective for a simple mercury nitrate solution. If sodium thiosulfate was added in the solution, thiosulfate interfered with the solution and the titration method was not effective. As a result the AAS method was adopted. Red mercury sulfide can be precipitated by simple aging of mercury thiosulfate solution. Parameters such as temperature, pH and thiosulfate concentration have an effect on the rate and extent of mercury sulfide precipitation. With an increase of temperature, thiosulfate concentration and at lower pH, the mercury precipitation rate increases. However at very high temperature such as 70ºC and 80ºC mercury precipitates as a mixture of red and black mercury sulfide. Thioselenate synthesis was attempted from a mixture of sodium sulfite and selenium powder. The reaction between sulfite and elemental selenium was too slow to be useful. The environmental stability of the mercury sulfide precipitates produced from thiosulfate solutions was investigated. Solid Waste Disposal Characterization (SWDC) tests were done to check the precipitation limit for land disposal and Resource Conservation and Recovery Act (RCRA).

description: This research examines how to bridge an existing gap between landscape design and maintenance within the overarching goal of supporting and enhancing ecological function in designed landscapes. Emerging from a practice-based problem, the research solution aims to bring together the working ecosystems of design and maintenance through a process of building strong and effective teams working towards common goals. The UK Design Council’s Double Diamond was used as the guiding framework for the development of the thesis problem and solution. Two research methodologies, Design Science Research and practice-based research were used to identify and solve the problem by generating new knowledge and insights around integrating ecological landscape design and maintenance. Three major components of research were conducted: 1) “On the Ground” interviews, 2) Key Informant interviews, and 3) a Practitioners Precedent review. These were used to inform the research solution, a “Model of Care”. The “Model of Care” is based on the fundamental principles of common values and goals, support structure, knowledge transfer, communication, and capacity-building. To test and describe the solution, four care archetypes were developed: 1) “Self”, 2) “Community”, 3) “Contractor”, and 4) “Staff”. For each of these archetypes, a persona and design fiction narrative were developed to describe how the “Model of Care” could be applied in practice. The research demonstrated how an integrated approach to design and care of landscapes can lead to better outcomes for not only ecologically designed landscapes, but designed landscapes in general. The research also illustrated the value and importance of reflection, innovation, and experimentation within a practice-based context towards solving complex challenges.
Global offensive $k$-alliances in digraphs

description: In this paper, we initiate the study of global offensive $k$-alliances in digraphs. Given a digraph $D=(V(D),A(D))$, a global offensive $k$-alliance in a digraph $D$ is a subset $S\subseteq V(D)$ such that every vertex outside of $S$ has at least one in-neighbor from $S$ and also at least $k$ more in-neighbors from $S$ than from outside of $S$, by assuming $k$ is an integer lying between two minus the maximum in-degree of $D$ and the maximum in-degree of $D$. The global offensive $k$-alliance number $γ_{k}^{o}(D)$ is the minimum cardinality among all global offensive $k$-alliances in $D$. In this article we begin the study of the global offensive $k$-alliance number of digraphs. For instance, we prove that finding the global offensive $k$-alliance number of digraphs $D$ is an NP-hard problem for any value $k\in \{2-Δ^-(D),\dots,Δ^-(D)\}$ and that it remains NP-complete even when restricted to bipartite digraphs when we consider the non-negative values of $k$ given in the interval above. Based on these facts, lower bounds on $γ_{k}^{o}(D)$ with characterizations of all digraphs attaining the bounds are given in this work. We also bound this parameter for bipartite digraphs from above. For the particular case $k=1$, an immediate result from the definition shows that $γ(D)\leq γ_{1}^{o}(D)$ for all digraphs $D$, in which $γ(D)$ stands for the domination number of $D$. We show that these two digraph parameters are the same for some infinite families of digraphs like rooted trees and contrafunctional digraphs. Moreover, we show that the difference between $γ_{1}^{o}(D)$ and $γ(D)$ can be arbitrary large for directed trees and connected functional digraphs.

description: This paper proposes a novel technique to reduce the computational burden associated with the simulation of localised failure. The proposed methodology affords the simulation of damage initiation and propagation whilst concentrating the computational effort where it is most needed, i.e. in the localisation zones. To do so, a local/global technique is devised where the global (slave) problem (far from the zones undergoing severe damage and cracking) is solved for in a reduced space computed by the classical Proper Orthogonal Decomposition, while the local (master) degrees of freedom (associated with the part of the structure where most of the damage is taking place) are fully resolved. Both domains are coupled through a local/global technique. This method circumvents the difficulties associated with model order reduction for the simulation of highly non-linear mechanical failure and offers an alternative or complementary approach to the development of multiscale fracture simulators.

description: We plan to analyse dust extinction in Lyman Break Galaxies (LBGs) by introducing a new and more reliable approach to their selection and to the characterization of their distribution of UV slopes beta, using deep IR images from HST. We exploit deep WFC3 IR observations of the ERS and HUDF fields over GOODS-South, combined with HST-ACS optical data, to select z~4 LBGs through a new (B-V) vs. (V-H) colour diagram. The UV slope of the selected galaxies is robustly determined by a linear fit over their observed I, Z, Y, J magnitudes, coherently with the original definition of beta. The same fit is used to determine their rest-frame UV magnitudes M1600 through a simple interpolation. We estimate the effect of observational uncertainties with detailed simulations that we also exploit, under a parametric maximum-likelihood approach, to constrain the probability density function of UV slopes PDF(beta) as a function of rest-frame magnitude. We find 142 and 25 robust LBGs in the ERS and HUDF fields respectively, limiting our sample to S/N(H)>10 objects. Our newly defined criteria improve the selection of z~4 LBGs and allow us to exclude red interlopers at lower redshift, especially z~3-3.5 objects. We find that z~4 LBGs are characterized by blue UV slopes, suggesting a low dust extinction: all L\simeq-2.1, while brighter objects only are slightly redder ( -1.9). We find an intrinsic dispersion ~ 0.3 for PDF(beta) at all magnitudes. The SFRD at z~4 corrected according to these estimates turns out to be lower than previously found: log(SFRD)\simeq-1.09 M_sun/yr/Mpc^3. Finally, we discuss how the UV slope of z~4 galaxies changes as a function of the dust-corrected UV magnitude (i.e. SFR) showing that most galaxies with a high SFR (> 80 M_sun/yr) are highly extincted objects.
