description: We explore scalar radiation from neutron star-black hole binaries in scalar-tensor theories with kinetic screening ($K$-essence). Using 3+1 numerical relativity simulations in the decoupling limit, we investigate scalar dipole and quadrupole radiation for different values of the strong coupling constant $Λ$. Our results show that kinetic screening effectively suppresses the scalar dipole radiation as $Λ$ decreases. This is validated by comparing to analytic predictions for the screening of dipole scalar emission, with which our numerical results show good agreement. However, our numerical simulations show that the suppression of scalar quadrupole radiation is less efficient, even when the screening radius exceeds the wavelength of the emitted radiation. In fact, the dependence of the scalar quadrupole amplitude on $Λ$ flattens out for the smallest $Λ$ that we can simulate, and the quadrupole amplitude is suppressed only by a factor $\lesssim 3$ relative to the Fierz-Jordan-Brans-Dicke case. Overall, our study shows that scalar quadrupole radiation from mixed binaries may be used to place constraints on $K$-essence theories with next-generation gravitational-wave detectors.

description: Photon-counting computed tomography (PCCT) marks a significant advancement over conventional energy-integrating detector (EID) CT systems. This review highlights PCCT's superior spatial and contrast resolution, reduced radiation dose, and multi-energy imaging capabilities, which address key challenges in radiotherapy, such as accurate tumor delineation, precise dose calculation, and treatment response monitoring. PCCT's improved anatomical clarity enhances tumor targeting while minimizing damage to surrounding healthy tissues. Additionally, metal artifact reduction (MAR) and quantitative imaging capabilities optimize workflows, enabling adaptive radiotherapy and radiomics-driven personalized treatment. Emerging clinical applications in brachytherapy and radiopharmaceutical therapy (RPT) show promising outcomes, although challenges like high costs and limited software integration remain. With advancements in artificial intelligence (AI) and dedicated radiotherapy packages, PCCT is poised to transform precision, safety, and efficacy in cancer radiotherapy, marking it as a pivotal technology for future clinical practice.

description: The goal of the acoustic scene classification (ASC) task is to classify recordings into one of the predefined acoustic scene classes. However, in real-world scenarios, ASC systems often encounter challenges such as recording device mismatch, low-complexity constraints, and the limited availability of labeled data. To alleviate these issues, in this paper, a data-efficient and low-complexity ASC system is built with a new model architecture and better training strategies. Specifically, we firstly design a new low-complexity architecture named Rep-Mobile by integrating multi-convolution branches which can be reparameterized at inference. Compared to other models, it achieves better performance and less computational complexity. Then we apply the knowledge distillation strategy and provide a comparison of the data efficiency of the teacher model with different architectures. Finally, we propose a progressive pruning strategy, which involves pruning the model multiple times in small amounts, resulting in better performance compared to a single step pruning. Experiments are conducted on the TAU dataset. With Rep-Mobile and these training strategies, our proposed ASC system achieves the state-of-the-art (SOTA) results so far, while also winning the first place with a significant advantage over others in the DCASE2024 Challenge.

description: We work out the unfolded formulation of the fields in the non-linear realisation of $E_{11}$. Using the connections in this formalism, we propose, at the linearised level, an infinite number of first-order duality relations between the dual fields in $E_{11}$. In this way, we introduce extra fields that do not belong to $E_{11}$ and we investigate their origin. The equations of motion of the fields are obtained by taking derivatives and higher traces of the duality relations.

Front-wheel friction drive electric bicycle motor

description: Many cyclists are seeking easy solutions to bring electric power to their bikes. Having an electric motor that can be switched on to get a boost going uphill, to go faster, or to simply take a break from pedaling can be very useful. With these motivations, we sought to develop a front-wheel friction-drive motor system that could be easily mounted and removed from any adult-sized road bike. The objective was to develop an easily mountable solution containing the motor, controller, battery pack, and throttle that could be installed within minutes. Friction-drive motors are a cheaper, lighter alternative to the more common hub motors that must be permanently attached to the wheel of the bike. Indeed, the motor mechanism component of our design weighs 1.45 kg, and the total weight of our design does not exceed 3 kg (depending on the size of battery pack used). The design of our solution was based on goal of keeping the installation as simple as possible, whilst ensuring that the mechanism could tolerate the strong rotational forces introduced by the motor. Our solution mounts at the handlebars by means of two snap-on clamps, as well as at the fender holes, located at the hub of the front wheel of the bicycle. The design can be adjusted at two locations: by changing the angle between a horizontal and a vertical cantilever, as well as by changing the height of the supporting rods. The motor is attached to a pivot point, such that is has sufficient room to engage and disengage with the front tire. Blocker pieces are located strategically to ensure that the motor does not swing too far back and get stuck in the wheel. The mechanical aspect of our solution has proven to be successful. We were able to mount the mechanism to five different bicycles, all of which varied greatly in handlebar shape and tire size. In all these cases, our solution was easily installed in under two minutes. Installing a user-friendly throttle proved to be very challenging. The most successful attempt entailed running the controller by means of a purchased servo tester circuit; however, our throttle setup was not functioning in time for us to do test ride our solution. We therefore cannot present meaningful results as the electrical efficiency of our system. We recommend three important actions to be taken to ensure that our solution be safe and fully-functional. First, all electrical parts should be protected in a water-proofed enclosure. Secondly, a push button throttle should be installed along with the servo tester circuit. Finally, we recommend that an emergency brake be installed to ensure the safety of the user in the case where the throttle or controller fails.

description: We extend the equivalence by Cockett and Garner between restriction monoids and ample categories to the setting of Boolean range semigroups which are non-unital one-object versions of range categories. We show that Boolean range semigroups are equivalent to ample topological categories where the range map $r$ is open, and étale Boolean range semigroups are equivalent to biample topological categories. These results yield the equivalence between étale Boolean range semigroups and Boolean birestriction semigroups and a characterization of when a Boolean restriction semigroup admits a compatible cosupport operation. We also recover the equivalence between Boolean birestriction semigroups and biample topological categories by Kudryavtseva and Lawson. Our technique builds on the usual constructions relating inverse semigroups with ample topological groupoids via germs and slices.

Publisher: name: The University of British Columbia

description: This report details the results of student work on an underwater remote operated vehicle (ROV) used to view sponge life on the sea floor of the Howe Sound (a depth of ~850ft). The ROV is to be ergonomically viable for operation by a single, or pair or researchers, as well as economical. This project is a continuation of work completed by a previous student team who produced a simple, incomplete, prototype. The ROV is not completed but significant advancements have been made. The project is currently a mechanical shell approximately 1m³ and weights 30kg (this includes electronic components) and several primary electrical systems. The mechanical shell has been extensively upgraded and remade to better fulfill the design requirements. One of the ROV’s defining characteristics is a pressure equalization system that allows deep diving without use of heavy and expensive structural supports. It works by connecting all water tight areas of the ROV to a SCUBA regulator and air tank. This passively maintains the air pressure ambient to the water thus greatly reducing the forces on the unit. Key mechanical features such at the pressure equalization systems, and leak free housings have been tested successfully. The PES is found to consume ~2.6 ft³ over a 15 min dive reaching 51 ft and back to the surface then 133ft and back to the surface. This confirms the model which predicts ~2.5 ft³ consumed. The major electrical systems have been designed, built and tested including the power, motor control and camera systems. The other defining characteristic is the single cable tether system which will carry all signals to and from the unit as well as power. This system has been successfully tested using AC video signal coupled with high voltage DC power. To improve the design t is recommended to clean up the wiring and mounting of the electrical systems as well as construct and test the LED lighting system. The mechanical design can be improved by strengthening some of the connections and supports as well as several wire ports need to added to integrate the required battery housing and electrical systems.

description: This study examines the role of trade unions and works councils in the context of labor migration in the West German shipbuilding industry from 1960 to 1983. Within two decades, originally booming and large shipyards were hit by an economic crisis with severe implications on the employment of migrant labor. Our findings, based on 29 oral history interviews with former staff of three leading shipyards and archival sources, show that although integration efforts existed, trade unions did not address emerging structural and subjective disadvantages and exclusions of workers with a migrant background. We identify discriminatory experiences, migratory agency and diverse union actor’s initiatives from below that have not been documented before.

description: We present the noncanonical Hamiltonian structure of the relativistic Euler equations for a perfect fluid in Minkowski spacetime. By identifying the system's noncanonical Poisson bracket and Hamiltonian, we show that relativistic fluid flows preserve helicity and enstrophy as conserved quantities in three-dimensional and two-dimensional cases, respectively. This holds when the fluid follows a relativistic $γ$-barotropic equation of state, which generalizes the classical barotropic condition. Furthermore, we demonstrate that these conserved quantities are Casimir invariants associated with the noncanonical Poisson structure. These findings open new avenues for applying Hamiltonian theory to the study of astrophysical fluids and relativistic plasmas.

description: Using the example of the Weimarer Republik, the author describes and evaluates different forms of protest by the unemployed, including organizing attempts within the workers movement and self-organization. Until now, such activities from the Weimar and other periods have hardly been taken notice of as a genuine part of the workers movement; they have simply been forgotten. However, insistence on autonomous organization and demonstrations of unusual headstrongness led to the development of a movement of the unemployed, the historical significance of which is gradually becoming discernible.

description: We consider an extended model with two real scalar fields, $ϕ(x,t)$ and $χ(x,t)$. The first sector is controlled by the sine-Gordon superpotential, while the second field is submitted to the $χ^4$ one. The fields mutually interact via a nontrivial coupling function $f(χ)$ that also changes the kinematics of $ϕ$. We briefly review the implementation of the Bogomol'nyi-Prasad-Sommerfield (BPS) prescription. We then solve the resulting BPS equations for two different interactions $f$. The first one leads to a single kink-kink configuration, while the second one gives rise to a inhomogeneous sine-Gordon kink lattice. We study the linear stability of these new solutions, focusing on their translational modes. We also explore how the strength of the mutual interaction affects the BPS profiles. In particular, we show that a homogeneous lattice with identical kinks is attained in the regime of extremely strong interactions.

Dorothea Biaback Anong situates her analysis of the German seasonal work regime before and during the pandemic within the long history of seasonal work migration to and within Germany. In doing so, she identifies continuities beyond the changes induced by the pandemic. Drawing on migration studies literature, the author discusses her central observation that the economic interest in migrant labor and the national-conservative interest in restricting migration—interests that otherwise conflict strongly in the political discourse on migration— merge and mutually reinforce each other in the political negotiations around seasonal migrant workers in agriculture.

Examining the sustainability of lawns on campus
Creators: name: Gray, Emily
Publisher: name: The University of British Columbia
Year: 2013

description: This report explores whether lawns can be considered a sustainable landscaping option in a campus setting. This was completed through an analysis of each of the three spheres of sustainability: environmental, social, and economic, in addition to a consideration of the use of lawns at specific universities. The following conclusions were generated: i. Campus lawns can be considered sustainable if they are managed in an environmentally conscious and sensitive manner at low levels of maintenance. • Recommendation: Manage lawns at a Level 4: “Open Space/Play” maintenance level as defined by the B.C. Landscape Standards. • Recommendation: Conduct future research to determine the balance between sustainable management practices and optimal lawn health. ii. Lawns provide an important environmental benefit through the sequestration of carbon. However, their low biodiversity and high water consumption must be considered in maintenance practices. • Recommendation: Allow dormancy in summer months or implement a rainwater collection program to supplement irrigation. • Recommendation: Use lawns in conjunction with pockets of trees and native vegetation to support biodiversity. iii. Socially, lawns are very sustainable because of their canonical place in campus landscaping. Examining the Sustainability of Lawns on Campus Emily Gray 3 iv. Economically, lawns can be considered sustainable because of their longevity and the low level of maintenance complexity they require. v. The use of lawns at the University of Washington and Simon Fraser University provides insights as to the environmental and social benefits of lawns. • Recommendation: Consider the environmental benefits that lawns provide in terms of stromwater filtration and the impact of this at the University of British Columbia.

description: Next-generation gravitational wave (GW) observatories, such as the Einstein Telescope (ET) and Cosmic Explorer, will observe binary neutron star (BNS) mergers across cosmic history, providing precise parameter estimates for the closest ones. Innovative wide-field observatories, such as the Vera Rubin Observatory, will quickly cover large portions of the sky with unprecedented sensitivity to detect faint transients. This study aims to assess the prospects for detecting optical emissions from BNS mergers with next-generation detectors, considering how uncertainties in neutron star (NS) population properties and microphysics may affect detection rates. Starting from BNS merger populations exploiting different NS mass distributions and equations of state (EOSs), we model the GW and kilonova (KN) signals based on source properties. We model KN ejecta through numerical-relativity informed fits, considering the effect of prompt collapse of the remnant to black hole and new fitting formulas appropriate for more massive BNS systems, like GW190425. We include optical afterglow emission from relativistic jets consistent with observed short gamma-ray bursts. We evaluate the detected mergers and the source parameter estimations for different geometries of ET, operating alone or in a network of current or next-generation GW detectors. Finally, we estimate the number of detected optical signals simulating realistic observational strategies by the Rubin Observatory. ET as a single observatory will enable the detection of about ten to a hundred KNe per year by the Rubin Observatory. This improves by a factor of about 10 already when operating in the network with current GW detectors. Detection rate uncertainties are dominated by the poorly constrained local BNS merger rate, and depend to a lesser extent on the NS mass distribution and EOS.

description: Cosmic (super)strings offer promising ways to test ideas about the early universe and physics at high energies. While in field theory constructions their tension is usually assumed to be constant (or at most slowly-varying), this is often not the case in the context of String Theory. Indeed, the tensions of both fundamental and field theory strings within a string compactification depend on the expectation values of the moduli, which in turn can vary with time. We discuss how the evolution of a cosmic string network changes with a time-dependent tension, both for long-strings and closed loops, by providing an appropriate generalisation of the Velocity One Scale (VOS) model and its implications. The resulting phenomenology is very rich, exhibiting novel features such as growing loops, percolation and a radiation-like behaviour of the long string network. We conclude with a few remarks on the impact for gravitational wave emission.

description: The Indian summer monsoon (ISM) and associated monsoon intraseasonal oscillations (MISOs) influence the billions of people living in the Indian subcontinent. This study explores the role of autoconversion parameterization in microphysical schemes for the simulation of MISO with the coupled climate model, e.g., the Climate Forecast System version 2 (CFSv2), by conducting sensitivity experiments in two resolutions (~100 km and ~38 km). Results reveal that the modified autoconversion parameterization better simulates the active-break spells of the ISM rainfall. The main improvements include the contrasting features of rainfall over land and ocean and the MISO index, representing MISO periodicity. The improvements are qualitatively and quantitatively more significant in the higher-resolution simulations, particularly regarding rainfall spatial patterns over the Indian subcontinent during active spells. The MISO monitoring index in the revised CFSv2 also shows improvement compared to the control run. This study concludes that proper autoconversion parameterization in the coupled climate model can lead to enhanced representation of active/break spells and sub-seasonal variability of ISM.

description: In his essay, Helmut Dietrich discusses current EU strategies for the repression of refugee assistance: on the one hand, the humanitarian-based criminalization of suspected boat drivers accused of smuggling and endangering human lives, and on the other, the formation of a kind of enemy criminal law against a solidary refugee monitoring that draws attention to the silent mass deaths in the Mediterranean and is increasingly being fought with paramilitary and intelligence methods. The unfettered and lawless prosecution of so-called boat drivers has now led to the emergence of a large new prison population in Greece, and the anti-terrorist charges and investigations against solidarity-based transnational grassroots initiatives are unprecedented in Europe. Helmut Dietrich proposes two responses to these criminalizations: developing an everyday political as well as social attention to “boat drivers” imprisoned in Southern Europe, and countering the criminalization of supporters on the EU periphery with refusal and protests in the EU centers.

description: In this article, we analyze the history of the 1929 crisis, and its political-economic outcome, with emphasis on employment fluctuations in Roosevelt’s New Deal in the USA and the country’s entry into World War II; the Spanish revolution, the French popular front and the civil war and the rise of Nazi-fascism as a product of the defeat of social revolutions. The absence of support on the part of the USSR and the social democracy for the revolutionary projects of the 30s of the 20th century contributed to this defeat; it resulted from the militant support of the German industrial and financial sector for this Nazi project, and of the inaction, if not active complicity, of social democracy and its alliances with semi-Bonapartist powers before Hitler’s rise to power. Its outcome was the greatest tragedy in human history.

description: Segmentation of cardiac magnetic resonance images (MRI) is crucial for the analysis and assessment of cardiac function, helping to diagnose and treat various cardiovascular diseases. Most recent techniques rely on deep learning and usually require an extensive amount of labeled data. To overcome this problem, few-shot learning has the capability of reducing data dependency on labeled data. In this work, we introduce a new method that merges few-shot learning with a U-Net architecture and Gaussian Process Emulators (GPEs), enhancing data integration from a support set for improved performance. GPEs are trained to learn the relation between the support images and the corresponding masks in latent space, facilitating the segmentation of unseen query images given only a small labeled support set at inference. We test our model with the M&Ms-2 public dataset to assess its ability to segment the heart in cardiac magnetic resonance imaging from different orientations, and compare it with state-of-the-art unsupervised and few-shot methods. Our architecture shows higher DICE coefficients compared to these methods, especially in the more challenging setups where the size of the support set is considerably small.

description: Developing efficient path integral (PI) methods for atomistic simulations of vibrational spectra in heterogeneous condensed phases and interfaces has long been a challenging task. Here, we present the h-CMD method, short for hybrid centroid molecular dynamics, that combines the recently introduced fast quasi-CMD (f-QCMD) method with fast CMD (f-CMD). In this scheme, molecules that are believed to suffer more seriously from the curvature problem of CMD, e.g., water, are treated with f-QCMD, while the rest, e.g., solid surfaces, are treated with f-CMD. To test the accuracy of the newly introduced scheme, the infrared spectra of the interfacial D2O confined in the archetypal ZIF-90 framework are simulated using h-CMD compared to a variety of other PI methods, including thermostatted ring-polymer molecular dynamics (T-RPMD) and partially adiabatic CMD as well as f-CMD and experiment as reference. Comparisons are also made to classical MD, where nuclear quantum effects are neglected entirely. Our detailed comparisons at different temperatures of 250-600 K show that h-CMD produces O-D stretches that are in close agreement with the experiment, correcting the known curvature problem and red-shifting of the stretch peaks of CMD. h-CMD also corrects the known issues associated with too artificially dampened and broadened spectra of T-RPMD, which leads to missing the characteristic doublet feature of the interfacial confined water, rendering it unsuitable for these systems. The new h-CMD method broadens the applicability of f-QCMD to heterogeneous condensed phases and interfaces, where defining curvilinear coordinates for the entire system is not feasible.

description: The PTGL web server provides a database of protein secondary structure topologies. It is based on protein ligand graphs computed by the VPLG software. The PTGL uses a graph-based model to describe the structure of proteins on the super-secondary structure level. This web server allows you to search for protein motifs which can be detected in the graphs. It also provides standardized 2D visualizations of protein graphs and folding graphs. In contrast to the manually curated CATH and SCOP databases, the method used by this server is fully automated. Similar servers, which also support substructure search, include ProSMoS and Pro-Origami.

description: Criticism of neoliberal globalisation has become associated with xenophobia, racism and nationalism, enabling far-right populist demagogues such as Marine Le Pen and Donald Trump to exploit working-class discontent with globalisation. Yet less than two decades ago a radical left-wing movement was seriously challenging globalisation and demonstrating that critique of corporate globalisation was compatible with internationalism and working-class solidarity across national borders. Where was labour in this important movement? Did unions participate in blockading the citadels of corporate power? Evidence from case studies of four mobilisations (Seattle November-December 1999, Melbourne September 2000, Québec City April 2001 and Genoa July 2001) suggests strong working-class involvement, especially of white-collar workers from the public sector, and important contributions from union activists and particular radical unions as organisations. However, trade union officials often preferred union contingents keep a safe distance from centres of action. Significant conflicts were apparent within unions between class-conscious activists, who wished to embrace the growing left-wing movement against globalisation, and more conservative officials. It confirmed the truism of union movement scholarship: the problem of full-time bureaucracies with interests distinct from those of rank-and-file workers; and the existence of the “universal tension” between the contradictory elements of “movement” and “organisation.” Ambivalence and prevarication did not present the union movement in the best possible light to workers angry and distressed by the effects of globalisation. Did the hesitant role played by unions in alter-globalisation campaigns contribute to union decline and prepare the ground for right-wing populist opposition to globalisation? Was this a lost moment for labour?

Possible options for reuse and recycling of end-of-life waste glass from deconstruction projects

Publisher: name: The University of British Columbia

description: Construction and demolition waste accounts for 20-30% of the waste in Canadian landfills. Of this, glass makes up about 1%. This number is comparatively small, but represents an extremely recyclable material that frequently ends up in landfills simply because there is little to no infrastructure in place that can accept it. The most important thing is to establish this infrastructure, whether it be in current glass recycling facilities or a deconstruction hub. Until this happens, the opportunity to recycle the glass is lost. While the best option is to reuse, this is often difficult with the glass from deconstruction, which is largely constituted of windows. These single pane windows are not energy efficient and cannot be effectively used in their current state. Therefore, the best option is to recycle the glass. Many of these options involve crushing the glass into cullet or fine aggregates. Some fields in which glass can be recycled include soil applications, construction and road building, and art and decoration. Currently, there are no options for obtaining residual materials from the glass if it cannot be reused or recycled. While most of this glass will likely come from deconstruction projects in the future, there is also some that comes from renovation projects and new construction. A deconstruction hub would greatly increase the amount of glass that is recycled, when paired with proper education on the subject. It is also important to gain higher levels of participation in deconstruction, which could be achieved by providing incentives like tax credits, and by mandating waste diversion minimums.

description: Masses of the singly heavy baryons (SHBs), composed of a heavy quark and a light diquark, are studied from the viewpoints of heavy-quark spin symmetry (HQSS) and chiral-symmetry restoration at finite temperature. We consider the light diquarks with spin-parity $J^P=0^\pm$ and $1^\pm$. Medium corrections to the SHBs are provided through the diquarks whereas the heavy quark is simply regarded as a spectator. The chiral dynamics of the diquark are described by the Nambu-Jona-Lasinio (NJL) model having (pseudo)scalar-type and (axial)vector-type four-point interactions and the six-point ones responsible for the $U(1)_A$ axial anomaly. The divergences are handled by means of the three-dimensional proper-time regularization with both ultraviolet and infrared cutoffs included, in order to eliminate unphysical imaginary parts. As a result, the mass degeneracies between the parity partners of all the SHBs are predicted in accordance with the chiral restoration. In particular, the HQS-doublet SHBs exhibit clear mass degeneracies due to the absence of the direct anomaly effects. We also predict a mass degeneracy of $Σ_c$ and $Ω_c$ above the pseudocritical temperature $T_{\rm pc}$ of chiral restoration, which results in a peculiar mass hierarchy for positive-parity HQS-doublet SHBs where $Ξ_c'$ becomes heavier than $Ω_c$ Besides, it is found that the decay width of $Σ_c\toΛ_cπ$ vanishes above $T_{\rm pc}$ reflecting a closing of the threshold. The predicted modifications of masses and decay widths of the SHBs are expected to provide future heavy-ion collision experiments and lattice simulations with useful information on chiral dynamics of the diquarks.
