description: The potential of circulating antideuterons ($\mathrm{\overline{d}}$) in the AD/ELENA facility at CERN is under active investigation. Approximately 100 $\mathrm{\overline{d}}$ per bunch could be delivered as a $100\,\mathrm{keV}$ beam based on measured cross-sections. These $\mathrm{\overline{d}}$ could be further decelerated to $12\,\mathrm{keV}$ using the GBAR scheme, enabling the synthesis of antideuterium ($\mathrm{\overline{D}}$) via charge exchange with positronium, a technique successfully demonstrated with $6\,\mathrm{keV}$ antiprotons for antihydrogen production. The AD/ELENA facility is currently studying the possibility of increasing the $\mathrm{\overline{d}}$ rate using an optimized new target geometry. Assuming this is feasible, we propose further enhancing the anti-atom production by using laser-excited positronium in the $2P$ state within a cavity, which is expected to increase the $\mathrm{\overline{D}}(2S)$ production cross-section by almost an order of magnitude for $\mathrm{\overline{d}}$ with $2\,\mathrm{keV}$ energy. We present the projected precision for measuring the antideuterium Lamb shift and extracting the antideuteron charge radius, as a function of the beam flux.

description: Hybrid Mamba-Transformer networks have recently garnered broad attention. These networks can leverage the scalability of Transformers while capitalizing on Mamba's strengths in long-context modeling and computational efficiency. However, the challenge of effectively pretraining such hybrid networks remains an open question. Existing methods, such as Masked Autoencoders (MAE) or autoregressive (AR) pretraining, primarily focus on single-type network architectures. In contrast, pretraining strategies for hybrid architectures must be effective for both Mamba and Transformer components. Based on this, we propose Masked Autoregressive Pretraining (MAP) to pretrain a hybrid Mamba-Transformer vision backbone network. This strategy combines the strengths of both MAE and Autoregressive pretraining, improving the performance of Mamba and Transformer modules within a unified paradigm. Experimental results show that the hybrid Mamba-Transformer vision backbone network pretrained with MAP significantly outperforms other pretraining strategies, achieving state-of-the-art performance. We validate the method's effectiveness on both 2D and 3D datasets and provide detailed ablation studies to support the design choices for each component.

Furthering Understanding of Neutral Rock Drainage Geochemistry Through Reactive Transport Modelling
Creators: name: Matlock, Blaise
Publisher: name: The University of British Columbia
Year: 2023

description: Mines generate millions of tonnes of waste rock over their lifespan, most of which will be stored in large piles exposed to the environment. Weathering of these waste rock piles over decades to millennia will release heavy metals and metalloids into the environment, potentially causing significant long-term environmental contamination. This is particularly a concern for waste rock with a high sulphide content, as oxidation of sulphidic waste rocks releases acidity and significant quantities of metals and metalloids. One inexpensive, simple, and effective method of contaminant attenuation in waste rock piles is the strategic layering of different waste rock types. This method utilizes geochemical processes that rely on the order infiltrating water encounters waste rock to minimize effluent contaminant concentrations. However, many geochemical mechanisms governing order-of-encounter effects are poorly understood. To develop a better understanding of the processes affecting metal and metalloid release and attenuation under neutral pH conditions and particularly of order-of-encounter effects, a reactive transport model was developed using MIN3P for the stacked waste rock barrels previously studied by Hirsche (2012) at the Antamina mine, Peru. A secondary objective of this model was to determine whether the geochemical mechanisms posited by Hirsche (2012) could explain the observed effluent lead, molybdenum, and zinc concentrations. The reactive transport model was also applied to the data-scarce Phu Thap Fah mine, Thailand, which has an extensive history of environmental contamination, to identify orders-of-encounter that could reduce effluent contaminant concentrations. Simulation results indicate that the reactive transport model is able to capture the main geochemical processes governing metal release and attenuation at Antamina, although the model has several limitations and did not predict all observed order-of-encounter effects. Some critical findings of the model are that silicate formation, as posited by Hirsche (2012), could explain the observed concentrations of zinc at Antamina, that copper surface complexation could be an important copper attenuation process at Antamina, and that lead and arsenic could be co-precipitating as the mineral mimetite (Pb5(AsO4)3Cl) at Antamina. When applied at Phu Thap Fah, the reactive transport model identified that layering sulphidic waste rock above calcite above gossan could result in improved effluent quality over the current waste rock management system. However, these results must be viewed with caution, since experimental data or field observations were not available to constrain the model.

description: Efficient and accurate measurement of the bi-directional reflectance distribution function (BRDF) plays a key role in high quality image rendering and physically accurate sensor simulation. However, obtaining the reflectance properties of a material is both time-consuming and challenging. This paper presents a novel method for minimizing the number of samples required for high quality BRDF capture using a gonio-reflectometer setup. Taking an image of the physical material sample as input a lightweight neural network first estimates the parameters of an analytic BRDF model, and the distribution of the sample locations. In a second step we use an image based loss to find the number of samples required to meet the accuracy required. This approach significantly accelerates the measurement process while maintaining a high level of accuracy and fidelity in the BRDF representation.

The space of quantum observables

description: Given a set of self-adjoint operators {Oi} n i=1 acting on some Hilbert space H, we aim to characterize the space of allowable quantum expectation values, {(⟨O1⟩ρ, ...,⟨On⟩ρ)|ρ ∈ D} ⊂ R n where D is the set of density operators. Our study constrains the problem by considering maximum entropy states and a central theme in our work is finding geometrical characterization of this space of expectation values. In this project, we have proven a number of general results in this direction including a complete description of the space of expectation values for commuting operators and 2 × 2 operators. We also prove generalizations of classical results from statistical mechanics as well as discuss how the generalized uncertainty principle could be used in our geometrical characterization. Finally, we apply the concepts of this thesis to the energy and pressure calculations of a special type of fermion lattice.

description: We experimentally determine the bounds of the magnetic-field-induced superconducting and magnetic phases near the crystalline $b$ axis of uranium ditelluride (UTe$_2$). By measuring the magnetoresistance as a function of rotation angle and field strength in magnetic fields as large as 41.5 T, we have studied these boundaries in three dimensions of magnetic field direction. The phase boundaries in all cases obey crystallographic symmetries and no additional symmetries, evidence against any symmetry-breaking quadrupolar or higher magnetic order. We find that the upper critical field of the zero-field superconducting state is well-described by an anisotropic mass model. In contrast, the angular boundaries of the $b$-axis-oriented field-reentrant superconducting phase are nearly constant as a function of field up to the metamagnetic transition, with anisotropy between the $ab$ and $bc$ planes that is comparable to the angular anisotropy of the metamagnetic transition itself. We discuss the relationship between the observed superconducting boundaries and the underlying $\mathbf{d}$ vector that represents the spin-triplet order parameter. Additionally, we report an unexplained normal-state feature in resistance and track its evolution as a function of field strength and angle.

description: Magnetoelectric coupling is crucial for uncovering fundamental phenomena and advancing technologies in high-density data storage and energy-efficient devices. The emergence of altermagnets, which unify the advantages of ferromagnets and antiferromagnets, offers unprecedented opportunities for magnetoelectric coupling. However, electrically tuning altermagnets remains an outstanding challenge. Here, we demonstrate how this challenge can be overcome by using antiferroelectricity and ferroelectricity to modulate the spin splitting in altermagnets, employing a universal, symmetry-based design principle supported by an effective model. We introduce an unexplored class of multiferroics: antiferroelectric altermagnets (AFEAM), where antiferroelectricity and altermagnetism coexist in a single material. From first-principles calculations, we validate the feasibility of AFEAM in well-established van der Waals metal thio(seleno)phosphates and perovskite oxides. We reveal the design of AFEAM ranging from two-dimensional monolayers to three-dimensional bulk structures. Remarkably, even a weak electric field can effectively toggle spin polarization in the AFEAM by switching between antiferroelectric and ferroelectric states. Our findings not only enrich the understanding of magnetoelectric coupling but also pave the way for electrically controlled spintronic and multiferroic devices.

description: JWST has revealed an abundance of compact, red objects at $z\approx5-8$ dubbed "little red dots" (LRDs), whose SEDs display a faint blue UV continuum followed by a steep rise in the optical. Despite extensive study of their characteristic V-shaped SEDs, the nature of LRDs remains unknown. We present a new analysis of the NIRSpec/PRISM spectrum of A2744-QSO1, a triply imaged LRD at $z=7.04$ from the UNCOVER survey. The spectrum shows a strong Balmer break and broad Balmer emission lines, both of which are difficult to explain with models invoking exclusively AGN or stellar contributions. Our fiducial model decomposes the spectrum into a post-starburst galaxy dominating the UV-optical continuum and a reddened AGN being sub-dominant at all wavelength and contributing at $\sim20\%$ level. However, our most credible model infers a stellar mass of $M_\star\approx 4\times10^9\,\mathrm{M_\odot}$ within a radius of $r_\mathrm{e}<30\,$pc, driving its central density to the highest among observations to date. This high central density could be explained if A2744-QSO-1 is the early-forming core of a modern-day massive elliptical galaxy that later puffed up via the inside-out growth channel. The models also necessitate an unusually steep dust law to preserve the strong break strength, though this steepness may be explained by a deficit of large dust grains. It is also probable that these challenges reflect our ignorance of A2744-QSO1's true nature. Future variability and reverberation mapping studies could help disentangle the galaxy and AGN contribution to the continuum, and deeper redder observations could also unveil the dust properties in LRDs.

description: The First Nations Health Authority (FNHA) created the We All Take Care of the Harvest (WATCH) Project to address seafood safety, security, and sovereignty among First Nations (FNs) Territories in response to growing concerns over the impacts of climate change on shellfish harvesting. In its pilot phase, the WATCH Project is investigating climatic shellfish harvesting closure trends in four FNs Territories in British Columbia (BC): Gitga’at First Nation, Klahoose First Nation, Malahat First Nation, and Tseshaht First Nation. The data necessary to investigate these trends, however, has been historically difficult to access because the data is collected and managed by various Canadian federal government departments. This report presents a preliminary analysis of the relationships between shellfish harvesting area biotoxin closures administered by Fisheries and Oceans Canada (DFO), environmental variables, and Canadian Food Inspection Agency (CFIA) marine biotoxin data from 2016 to 2022. For the purposes of this study, the environmental variables of interest include Pacific Decadal Oscillation (PDO), Oceanic Niño Index (ONI), Sea Surface Temperature (SST), and salinity. The marine biotoxins include those associated with amnesic shellfish poisoning (ASP), diarrhetic shellfish poisoning (DSP), and paralytic shellfish poisoning (PSP).

description: We present the emergence of topological phase transition in the minimal model of two dimensional rock-paper-scissors cycle in the form of a doublet chain. The evolutionary dynamics of the doublet chain is obtained by solving the anti-symmetric Lotka-Volterra equation. We show that the mass decays exponentially towards edges and robust against small perturbation in the rate of change of mass transfer, a signature of a topological phase. For one of the configuration of our doublet chain, the mass is transferred towards both edges and the bulk is gaped. Further, we confirm this phase transition within the framework of topological band theory. For this we calculate the winding number which change from zero to one for trivial and a non-trivial topological phases respectively.

description: A standard method to reduce the linewidth of semiconductor lasers involves the use of external optical feedback (EOF). However, feedback powers less than 1 % usually trigger coherence collapse (CC), leading to chaotic laser dynamics and linewidth broadening. This paper explores a method to mitigate CC through precise tuning of the feedback polarization depending on the feedback power. We report a semiconductor laser with a sub-100 Hz intrinsic linewidth, achieved via EOF. The laser features a U-shaped cavity with two sampled grating distributed Bragg reflectors (SG-DBRs), enabling broad tunability across a 42 nm wavelength range (1513-1555 nm). By injecting optical feedback into both sides of the laser cavity via an external fiber-based cavity, we reduce the intrinsic linewidth by more than three orders of magnitude, from MHz to sub-kHz across the laser's tuning range. By dynamically tuning the polarization, we demonstrate sub-100 Hz intrinsic linewidths at feedback powers up to 10 %, marking an improvement over prior studies where CC limited performance.

description: During the rapid changes occurring in human societies during the current century due to the rapid advancement in information and communication technology, it has become difficult to dispense with these tools in many fields of human life, including education. This field has sought to keep pace with these advancements and changes by adopting new scientific methods that align with the requirements of these changes. One of those methods is distance learning, which represents an advanced form of education. This type of education has contributed to solving many educational challenges due to its characteristics and advantages. It has also provided new opportunities for both students and teachers alike. However, this type of education is not without its fair share of challenges that it has encountered. This research aims to shed light on the challenges of distance learning of the Arabic language, especially in Africa. The Arabic language is taught and used in many African countries due to the cultural and historical influence of the Arab world in the region. In addition to the religious importance of the language in Islam, however, there are challenges facing the process of learning and teaching the Arabic language in those communities. The research also aims to propose some solutions that help overcome some of these challenges.

description: Event-based visual odometry is a specific branch of visual Simultaneous Localization and Mapping (SLAM) techniques, which aims at solving tracking and mapping subproblems (typically in parallel), by exploiting the special working principles of neuromorphic (i.e., event-based) cameras. Due to the motion-dependent nature of event data, explicit data association (i.e., feature matching) under large-baseline view-point changes is difficult to establish, making direct methods a more rational choice. However, state-of-the-art direct methods are limited by the high computational complexity of the mapping sub-problem and the degeneracy of camera pose tracking in certain degrees of freedom (DoF) in rotation. In this paper, we tackle these issues by building an event-based stereo visual-inertial odometry system on top of a direct pipeline. Specifically, to speed up the mapping operation, we propose an efficient strategy for sampling contour points according to the local dynamics of events. The mapping performance is also improved in terms of structure completeness and local smoothness by merging the temporal stereo and static stereo results. To circumvent the degeneracy of camera pose tracking in recovering the pitch and yaw components of general 6-DoF motion, we introduce IMU measurements as motion priors via pre-integration. To this end, a compact back-end is proposed for continuously updating the IMU bias and predicting the linear velocity, enabling an accurate motion prediction for camera pose tracking. The resulting system scales well with modern high-resolution event cameras and leads to better global positioning accuracy in large-scale outdoor environments. Extensive evaluations on five publicly available datasets featuring different resolutions and scenarios justify the superior performance of the proposed system against five state-of-the-art methods.

description: This work introduces Transformer-based Off-Policy Episodic Reinforcement Learning (TOP-ERL), a novel algorithm that enables off-policy updates in the ERL framework. In ERL, policies predict entire action trajectories over multiple time steps instead of single actions at every time step. These trajectories are typically parameterized by trajectory generators such as Movement Primitives (MP), allowing for smooth and efficient exploration over long horizons while capturing high-level temporal correlations. However, ERL methods are often constrained to on-policy frameworks due to the difficulty of evaluating state-action values for entire action sequences, limiting their sample efficiency and preventing the use of more efficient off-policy architectures. TOP-ERL addresses this shortcoming by segmenting long action sequences and estimating the state-action values for each segment using a transformer-based critic architecture alongside an n-step return estimation. These contributions result in efficient and stable training that is reflected in the empirical results conducted on sophisticated robot learning environments. TOP-ERL significantly outperforms state-of-the-art RL methods. Thorough ablation studies additionally show the impact of key design choices on the model performance.

Creators: name: Egamberdiyeva, Husnora
Publisher: name: Zenodo
Year: 2025

description: This study investigates strategies for differentiation and inclusion designed to address the varied learning needs of students in English as a Foreign Language (EFL) classrooms. Recognizing that EFL learners represent a spectrum of linguistic proficiency, cultural backgrounds, learning styles, and educational experiences, this research explores the challenges teachers face in creating equitable learning environments that promote the success of all students. The study employs a mixed-methods approach, combining quantitative data on student performance and engagement with qualitative data from teacher interviews and classroom observations. The findings reveal the effectiveness of specific differentiated instruction techniques, such as tiered assignments, flexible grouping, and personalized learning plans, in meeting individual student needs. Moreover, the research highlights the importance of culturally responsive teaching practices and inclusive classroom management strategies in fostering a sense of belonging and promoting active participation among all learners. This thesis emphasizes the need for ongoing professional development and systemic support to empower EFL teachers to effectively implement differentiation and inclusion, ultimately advocating for a more equitable and effective EFL learning experience for all students. The research concludes by providing recommendations for teacher training programs and classroom practices.
Streets-Tian Conjecture holds for 2-step solvmanifolds

description: A Hermitian-symplectic metric is a Hermitian metric whose Kähler form is given by the $(1,1)$-part of a closed $2$-form. Streets-Tian Conjecture states that a compact complex manifold admitting a Hermitian-symplectic metric must be Kählerian (i.e., admitting a Kähler metric). The conjecture is known to be true in dimension $2$ but is still open in dimensions $3$ or higher. In this article, we confirm the conjecture for all 2-step solvmanifolds, namely, compact quotients of 2-step solvable Lie groups by discrete subgroups. In the proofs, we adopted a method of using special {\em non-unitary} frames, which enabled us to squeeze out some hidden symmetries to make the proof go through. Hopefully the technique could be further applied.

Roots of Belonging : Dis/connection of an Immigrant Child

description: Leaving a home to set up a new home elsewhere is as much a source of excitement as it is a source of sorrow. We often end up in a double-bind of experiencing sadness for leaving behind people we love and cherish, and also struggling with the loneliness of social isolation and cultural adjustment in a new environment. This is especially difficult for children who, while culturally and linguistically adjusting, also end up shouldering the domestic load of being the liaison between their families and the outside world. And sometimes, all it takes is that one serendipitous encounter with that one individual who helps change perspectives, provides assurances, and gives confidence to the immigrant child to know how to find a niche for themselves in this new cultural environment. If you had been in a similar situation, who was that one person for you – or perhaps it was a group of people? And what changes occurred as a result of that encounter? Read through Maya’s beautifully illustrated story of just such an encounter and I dare you to not feel like smiling at the end.

description: LiDAR (Light Detection and Ranging) has become an essential part of the remote sensing toolbox used for biosphere monitoring. In particular, LiDAR provides the opportunity to map forest leaf area with unprecedented accuracy, while leaf area has remained an important source of uncertainty affecting models of gas exchanges between the vegetation and the atmosphere. Unmanned Aerial Vehicles (UAV) are easy to mobilize and therefore allow frequent revisits to track the response of vegetation to climate change. However, miniature sensors embarked on UAVs usually provide point clouds of limited density, which are further affected by a strong decrease in density from top to bottom of the canopy due to progressively stronger occlusion. In such a context, discriminating leaf points from wood points presents a significant challenge due in particular to strong class imbalance and spatially irregular sampling intensity. Here we introduce a neural network model based on the Pointnet ++ architecture which makes use of point geometry only (excluding any spectral information). To cope with local data sparsity, we propose an innovative sampling scheme which strives to preserve local important geometric information. We also propose a loss function adapted to the severe class imbalance. We show that our model outperforms state-of-the-art alternatives on UAV point clouds. We discuss future possible improvements, particularly regarding much denser point clouds acquired from below the canopy.

description: Kitaev quantum spin liquids (KSLs) in layered honeycomb magnets are known to host Majorana quasiparticles, whose excitations depend strongly on the direction of the applied magnetic field. In the high-field phase of $α$-RuCl$_3$, specific heat measurements have revealed characteristic field-angle dependence of low-energy excitations consistent with the Kitaev model, providing bulk evidence for the KSL state. Here we present low-temperature measurements of specific heat $C(T)$ for another KSL candidate $\textrm{Na}_2\textrm{Co}_2\textrm{Te}\textrm{O}_6$ (NCTO) under field rotation within the honeycomb plane. Above the critical field of antiferromagnetic order, the field-angle dependence of $C/T$ exhibits minima along the bond directions, contrasting with the maxima observed in the KSL state of $α$-RuCl$_3$. Our analysis indicates nodeless, fully-gapped excitations, which are inconsistent with the angle-dependent Majorana excitations with gapless nodes predicted by the Kitaev model. These findings suggest that low-energy excitations in NCTO are governed by gapped magnon excitations rather than Majorana quasiparticles, providing thermodynamic evidence against a KSL state.

description: This paper presents a new method for learning dissipative Hamiltonian dynamics from a limited and noisy dataset. The method uses the Helmholtz decomposition to learn a vector field as the sum of a symplectic and a dissipative vector field. The two vector fields are learned using two reproducing kernel Hilbert spaces, defined by a symplectic and a curl-free kernel, where the kernels are specialized to enforce odd symmetry. Random Fourier features are used to approximate the kernels to reduce the dimension of the optimization problem. The performance of the method is validated in simulations for two dissipative Hamiltonian systems, and it is shown that the method improves predictive accuracy significantly compared to a method where a Gaussian separable kernel is used.

description: The STS detector in the CBM experiment delivers data via multiple e-links connected to GBTX ASICs. In the process of data aggregation, that data must be received, combined into a smaller number of streams, and packed into so-called microslices containing data from specific periods. The aggregation must consider data randomization due to amplitude-dependent processing time in the FEE ASICs and different occupancy of individual e-links. During the development of the STS readout, the continued progress in the available technology affected the requirements for data aggregation, its architecture, and algorithms. The contribution presents considered solutions and discusses their properties.
