description: We use supersymmetric generalised unitarity to calculate supercoefficients of box functions in the expansion of scattering amplitudes in N=8 supergravity at one loop. Recent advances have presented tree-level amplitudes in N=8 supergravity in terms of sums of terms containing squares of colour-ordered Yang-Mills superamplitudes. We develop the consequences of these results for the structure of one-loop supercoefficients, recasting them as sums of squares of N=4 Yang-Mills expressions with certain coefficients inherited from the tree-level superamplitudes. This provides new expressions for all one-loop box coefficients in N=8 supergravity, which we check against known results in a number of cases.

Open Source AI in the System of Intellectual Property: A Gentle Introduction
Creators: name: Emanuilov, Ivo
Publisher: name: Zenodo
Year: 2023

description: Open Source AI does not fit well into the system of intellectual property. At best, it is a hybrid combination of IP assets, such as code protected as computer programs, databases protected under sui generic rights, and unprotected facts and data. Open source AI licensing, therefore, does not and cannot work in a similar way as it has for open source software. This presentation discusses the issues with the current draft definition of Open Source AI, which focuses on an operational AI system instead of the raw computational artefacts. It also presents the latest rules on copyright in the AI Act and the exemption of non-high-risk models released under a free and open source licence. The main recommendation for transactional lawyers is to follow established best practice, such as using proven and widely adopted open source licences, even if they do no apply squarely to AI. The main recommendation for the future definition of Open Source AI is to rethink licensing as a reasoning framework and turn to dealing with more vs less restrictive terms of use. In other words, contractual and not IP licensing terms are expected to take centre stage with the adoption of Open Source AI.
Stick-release pattern in stretching single condensed polyelectrolyte toroids

description: Using Langevin dynamics simulations, we study elastic response of single semiflexible polyelectrolytes to an external force pulling on the chain ends, to mimic the stretching of DNA molecules by optical tweezers. The linear chains are condensed by multivalent counterions into toroids. The force-extension curve shows a series of sawtooth-like structure, known as the stick-release patterns in experiments. We demonstrate that these patterns are a consequence of the loop-by-loop unfolding of the toroidal structure. Moreover, the dynamics, how the internal structure of chain varies under tension, is examined. At the first stage of the stretching, the toroidal condensate decreases its size until the loss of the first loop in the toroid and then, oscillates around this size for the rest of the unfolding process. The normal vector of the toroid is pulled toward the pulling-force direction and swings back to its early direction repeatedly when the toroidal chain looses a loop. The results provide new and valuable information concerning the elasticity and the microscopic structure and dynamic pathway of salt-condensed DNA molecules being stretched.

description: Mountain ungulates around the world have been decimated to small, fragmented populations. Restoring these species often is limited by inadequate information on where suitable habitat is found, and which restoration measures would help to increase and link existing populations. We developed an approach to spatially target threat-specific restoration actions and demonstrate it for bezoar goats (Capra aegagrus) in the Caucasus. Using a large occurrence dataset, we identified suitable habitat patches and evaluate them in terms of connectivity, protection status, and competition with other mountain ungulates. We found extant bezoar goat populations to be highly isolated, yet with widespread areas of suitable, unoccupied habitat between them. Many unoccupied habitat patches were well-connected to extant populations, were at least partly protected, and have low potential for competition with other Capra species. This signals substantial pressure on bezoar goats, likely due to poaching, which currently prevents natural recolonization. Our study shows how restoration planning is possible in the face of multiple threats and scarce data. For bezoar goats in the Caucasus, we pinpoint priority patches for specific restoration measures, including reintroductions and anti-poaching action. We highlight that many patches would benefit from multiple interventions and that transboundary restoration planning is needed, a situation likely similar for many mountain ungulates around the world.
Kinematics of OB-associations and the new reduction of the Hipparcos data

description: The proper motions of OB-associations computed using the old (Hipparcos 1997} and new (van Leeuwen 2007) reductions of the Hipparcos data are in a good agreement with each other. The Galactic rotation curve derived from an analysis of line-of-sight velocities and proper motions of OB-associations is almost flat in the 3-kpc neighborhood of the Sun. The angular rotation velocity at the solar distance is Omega_0=31 +/-1 km s-1 kpc-1. The standard deviation of the velocities of OB-associations from the rotation curve is sigma=7.2 km s-1. The distance scale for OB associations (Blaha & Humphreys 1989) should be shortened by 10-20%. The residual velocities of OB-associations calculated for the new and old reductions differ, on average, by 3.5 km s-1. The mean residual velocities of OB-associations in the stellar-gas complexes depend only slightly on the data reduction employed.

description: We present a prototype for the first tracking detector consisting of 250 micron thin scintillating fibers and silicon photomultiplier (SiPM) arrays. The detector has a modular design, each module consists of a mechanical support structure of 10mm Rohacell foam between two 100 micron thin carbon fiber skins. Five layers of scintillating fibers are glued to both top and bottom of the support structure. SiPM arrays with a channel pitch of 250 micron are placed in front of the fibers. We show the results of the first module prototype using multiclad fibers of types Bicron BCF-20 and Kuraray SCSF-81M that were read out by novel 32-channel SiPM arrays from FBK-irst/INFN Perugia as well as 32-channel SiPM arrays produced by Hamamatsu. A spatial resolution of 88 micron +/- 6 micron at an average yield of 10 detected photons per minimal ionizig particle has been achieved.

description: Rapidly rotating neutron stars can be unstable to the gravitational-wave-driven CFS mechanism if they have a neutral point in the spectrum of nonaxisymmetric f-modes. We investigate the frequencies of these modes in two sequences of uniformly rotating polytropes using nonlinear simulations in full general relativity, determine the approximate locations of the neutral points, and derive limits on the observable frequency band available to the instability in these sequences. We find that general relativity enhances the detectability of a CFS-unstable neutron star substantially, both by widening the instability window and enlarging the band into the optimal range for interferometric detectors like LIGO, VIRGO, and GEO-600.

description: Dynamically corrected gates were recently introduced [Khodjasteh and Viola, Phys. Rev. Lett. 102, 080501 (2009)] as a tool to achieve decoherence-protected quantum gates based on open-loop Hamiltonian engineering. Here, we further expand the framework of dynamical quantum error correction, with emphasis on elucidating under what conditions decoherence suppression can be ensured while performing a generic target quantum gate, using only available bounded-strength control resources. Explicit constructions for physically relevant error models are detailed, including arbitrary linear decoherence and pure dephasing on qubits. The effectiveness of dynamically corrected gates in an illustrative non-Markovian spin-bath setting is investigated numerically, confirming the expected fidelity performance in a wide parameter range. Robutness against a class of systematic control errors is automatically incorporated in the perturbative error regime.

Detection and localization of individual free street parking spaces using artificial intelligence and motion estimation
Creators: name: Bazzaza, Tala
Publisher: name: University of British Columbia
Year: 2024

description: Traffic congestion has become a universal phenomenon in metropolitan cities. The prevalence of congested roads not only results in delays, increased fuel consumption, environmental pollution, and a reduced quality of life but also contributes to lowered productivity levels due to the significant time wasted in the search for available parking spaces. Current solutions are either tailored solely for detecting vacant spaces within parking lots or rely on unfeasible street sensors and stationary surveillance cameras, simply falling short in accurately pinpointing individual free street parking spots. In this thesis, we introduce an innovative real-time street parking detection and localization system designed to cater to both human-driven and autonomous vehicles. Our solution is specifically engineered to be integrated into modern vehicles, utilizing the live video feed from the car's built-in navigation and obstacle avoidance cameras. This approach merges convolutional neural networks, video global motion analysis, and a distance measurement technique, enabling accurate detection and precise localization of vacant street parking spaces. Our proposed solution eliminates the influence of car speed, prevents redundant detection of the same parking spot during abrupt stops, and reduces computational costs and complexity. We introduce a unique and comprehensive dataset tailored for this objective, serving as the cornerstone for training and evaluating established object detection network architectures to identify the one that strikes the best balance between accuracy and computational efficiency and thus aligns with the prerequisites of integrating this solution into each vehicle. Performance evaluations confirm the proposed method’s efficacy across all types of scenarios.
Using Dynamic Software to Address Common College Calculus Stumbling Blocks

Year: 2014

description: There are specific topics in college calculus that can be major stumbling blocks for students. Having taught college calculus for four years to over a thousand students, we observed that even the students who have already taken pre-calculus or calculus during their high school careers had common misunderstandings. Students may remember a technique without retaining the understanding of why it can be applied or what it is accomplishing, essentially only having knowledge of a rote procedure. Educators can address these areas of difficulty by regularly utilizing dynamic technologies such as Geometer’s Sketchpad and Desmos in the classroom to fully illustrate calculus concepts. With these tools, teachers can help their students better understand how to reason mathematically in calculus.

description: Los estudios sociales acerca del desarrollo comunitario en América Latina y el Caribe constituyen un campo científico que ha sido poco estudiado y delimitado. La Región ha sido víctima de paradigmas eurocentristas y de la colonialidad del saber. A partir del 2008, con los cambios políticos ocurridos en el continente, se potenciaron políticas sociales con enfoque comunitario. Esta investigación investigación tiene como propósito delimitar la estructura del campo científico de los estudios sociales acerca del desarrollo comunitario en América Latina y el Caribe. El estudio parte de una perspectiva mixta que integra el análisis teórico con la aplicación de instrumentos empíricos. La investigación clasificó como analítico – descriptiva a partir del empleo de una posición intermedia entre el internalismo y el externalismo desde la sociología del conocimiento en combinación con las potencialidades del método bibliométrico. Se identificaron los agentes, capitales en juego, perspectivas teóricas y metodológicas del campo. Se concluyó que el campo científico de los estudios sociales acerca del desarrollo comunitario en la Región se estructura a partir de escasas instituciones, redes y asociaciones profesionales especializadas, mostrando el predominio de enfoques dominantes de la ciencia, siendo consecuente con la dinámica de autoconservación.

description: In this commentary, I aim to describe, contextualise and analyse my artistic practice, and present a cross-section of compositions and improvisations created between 2014- 2017. This includes site-specific compositions I created with installation artist Haroon Mirza, realising the previously lost composition of composer Daphne Oram titled ‘Still Point’, and my live turntable improvisations I create for my NTS Radio shows. I draw attention to my own bespoke techniques and unique methodology within my practice to create new forms of music composition as well as to study perspective both musically and socially. I highlight the important elements of my work including improvisation, untold histories of classical music, collaboration, artistic curation and my own methods of music electronics specifically relating to the turntable. In relation to my turntabling practice, I created my own methods away from any other culture such as hip-hop turntablism, instead focussing on the physicality of sound and the sculpture of the turntable as inspiration for my movement-based techniques. In regards to this, I discuss my strong focus on musicality, away from sound-art. The physicality of sound is also an integral element of my acoustic compositions. In relation to this, I outline the use of innovation in my work including engaging with space and acoustic as a way of creating sonic-sculptures that emphasise the idea of the physicality of sound, which is prevalent in different forms in my acoustic and electronic works. Throughout the commentary I aim to raise questions, and how we as artists have responsibilities to create new forms that are relevant to current social landscapes. Finally, the aim of all the points outlined is to continue to develop my main aim as an artist: The pursuit of truth and understanding on my quest to find “real.”

description: A novel and relatively simple method of production of electrodes for a multi-channel wire gas multiplier is developed. Two modifications of the multipliers have been tested: with a multiplication of electrons between two wire electrodes, MWGEM, and between a wire electrode and continuous anode, MWCAT. For both MWGEM and MWCAT detectors, filled with neon under pressure of 760 Torr and irradiated by beta-particles (Ni-63), the coefficient of proportional multiplication of electrons up to 10000 was obtained. For the MWGEM detector irradiated by alpha-particles (Pu-239), the coefficient of proportional multiplication of 300 was obtained. It is observed, that in contrast to the GEM detectors, produced by perforation of a metal-clad plastic foil, in a MWGEM the discharges do not destroy its electrodes even for the potentials above the threshold of discharges. The results on operation of the MWCAT filled with Ar, Ar+CH4 and Ar+1% Xe are also presented.

In the modern world, sustainable development is one of the most critical matters that society must address.  The hunt for innovative and sustainable solutions has been prompted by the need to lessen our carbon footprint and safeguard resources for future generations. Nano particle prepared via green route is the solution for above mentioned social issue.  In order to prepare sized-controlled Strontium titanate nanoparticle, a perovskite material for energy storage devices, we used green combustion with citrus-limon as the fuel.  PXRD and SEM tools were used to analyze the structural morphology of the as prepared NP's.  Narrow particle size, with blue shift in absorption edge suggest that, method of preparation is a good choice to produce SrTiO3 NP which has enhanced dielectric constant values than other reported method which make use of these particles in Energy storage devices.

description: The physical principles are studied for the optimal design of a quantum multiwell heterostructure working as an electrostatic energy storage device. We performed the search for an optimal multiwell trapping potential for electrons that results in the maximum static palarizability of the system. The response of the heterostructure is modeled quantum mechanically using nonlocal linear response theory. Three main design strategies are identified, which lead to the maximization of the stored energy. We found that the efficiency of each strategy crucially depends on the temperature and the broadening of electron levels. The energy density for optimized heterostructures can exceed the nonoptimized value by a factor more than $400$. These findings provide a basis for the development of new nanoscale capacitors with high energy density storage capabilities.

description: Relativistic models developed for the exclusive and inclusive quasielastic (QE) electron scattering have been extended to charged-current (CC) and neutral-current (NC) neutrino-nucleus scattering. Different descriptions of final-state interactions (FSI) are compared. For the inclusive electron scattering the relativistic Green's function approach is compared with calculations based on the use of relativistic purely real mean field potentials in the final state. Both approaches lead to a redistribution of the strength but conserving the total flux. Results for the differential cross section at different energies are presented. Scaling properties are also analyzed and discussed

description: Preservice teachers often enter teacher education programs with naïve views about mathematics and science as well as the various domains of knowledge needed for effective teaching. A significant body of research has demonstrated that teacher knowledge is multifaceted and consists of both subject matter knowledge and pedagogical content knowledge. In this study, a cohort of preservice elementary teachers participated in an activity involving two components of subject matter knowledge (factual/procedural and conceptual).

High Survival Rates and Associated Factors Among Ebola Virus Disease Patients Hospitalized at Donka National Hospital, Conakry, Guinea
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background—Anecdotal reports suggesting that survival rates among hospitalized patients with Ebola virus disease in Guinea are higher than the 29.2% rate observed in the current epidemic in West Africa. Methods—Survival after symptom onset was determined using Kaplan Meier survival methods among patients with confirmed Ebola virus disease treated in Conakry, Guinea from March 25, 2014, to August 5, 2014. We analyzed the relationship between survival and patient factors, including demographics and clinical features. Results—Of the 70 patients analyzed [mean age ± standard deviation (SD), 34 ± 14.1; 44 were men], 42 were discharged alive with a survival rate among hospitalized patients of 60% (95% confidence interval, 41.5–78.5%). The survival rate was 28 (71.8%) among 39 patients under 34 years of age, and 14 (46.7%) among 30 patients aged 35 years or greater (p = 0.034). The rates of myalgia (3 of 42 versus 7 of 28, p = 0.036) and hiccups (1 of 42 versus 5 of 28, p = 0.023) were significantly lower among patients who survived. Conclusions—Our results provide insights into a cohort of hospitalized patients with Ebola virus disease in whom survival is prominently higher than seen in other cohorts of hospitalized patients.

description: We present an experiment where we tune the decoherence in a quantum interferometer using one of the simplest object available in the physic of quantum conductors : an ohmic contact. For that purpose, we designed an electronic Mach-Zehnder interferometer which has one of its two arms connected to an ohmic contact through a quantum point contact. At low temperature, we observe quantum interference patterns with a visibility up to 57%. Increasing the connection between one arm of the interferometer to the floating ohmic contact, the voltage probe, reduces quantum interferences as it probes the electron trajectory. This unique experimental realization of a voltage probe works as a trivial which-path detector whose efficiency can be simply tuned by a gate voltage.

Optimizing systems to enable genetic engineering of transfusable platelets
Creators: name: Leung, Jerry
Publisher: name: University of British Columbia

description: Platelet transfusions are essential for managing bleeding and hemostatic dysfunction, but may become ineffective during certain circumstances such as in trauma. Optimizing systems that can enhance the hemostatic potential of platelets could lead to increased efficacy of transfusions and improve patient outcomes. Modifying transfusable donor platelets to express therapeutic proteins is the most direct method to enhance platelets. However, no appropriate methods exist for genetically modifying platelets collected from blood donors. This thesis showed that platelet-optimized lipid nanoparticles containing mRNA (mRNA-LNP) enable exogenous protein expression in human and rat platelets. Exogenous protein expression did not appear to require, nor correlate with platelet activation. Transfected platelets retained hemostatic function and accumulated in regions of vascular damage after transfusion into rats with hemorrhagic shock. These results suggest that platelets can be genetically modified without impairing hemostasis, where further optimization can expand the therapeutic potential of platelets. Engineering the platelet precursor cells, megakaryocytes (MKs), can also yield modified platelets, but can only currently be achieved through viral vectors. No methods currently exist to genetically modify MKs with non-viral techniques. mRNA-LNP represent a scalable strategy to transfect and modify MKs with a variety of nucleic acid payloads. This thesis showed that the clinically approved mRNA-LNP can transfect cord-blood derived MKs without affecting MK maturation. Expression of the coagulation factor VII (FVII) also decreased clot time in FVII-deficient plasma when assessed through rotational thromboelastometry. This was the first study to demonstrate LNP transfection of in vitro cultured MKs. Optimizing LNP further can create highly potent systems that may enable improved transfection of both platelets and MKs. This thesis showed that formulating LNP in the presence of high concentration pH 4 buffer can induce “bleb” structures and improve the transfection potency both in vitro and in vivo. Induction of bleb structure and improved potency is dependent on the type of pH 4 buffer employed, and the improved transfection potencies can be partially attributed to enhanced integrity of the encapsulated mRNA. These results suggest that enhanced transfection can be achieved by optimizing formulation parameters to improve mRNA stability through formation of bleb structures.

description: During his 55-year career as a highly distinguished scientist, Duncan Greenwood made a major contribution to the field of soil science and plant nutrition. His early studies on soil aeration revolutionized thinking on the mechanisms by which oxygen influences the activity of microorganisms and their metabolism of organic substances in structured soil. His ideas resulted in the ‘micro-site concept of soil aeration’, which is still widely accepted today. Later he turned his attention to the nutritional requirements of vegetable crops at a time when the horticultural industry was starting to introduce inorganic fertilizers. He developed a novel static model of N, P and K response, which he used to produce the first scientifically based inorganic fertilizer recommendations for 23 different vegetable crops. Not satisfied with this major development, Duncan started to create more sophisticated dynamic models using novel widely applicable relationships that took more account of the effects of weather on nutrient behaviour in the soil and plant. He not only used these to provide important insights into many of the complex interacting processes involved, but also incorporated them into some of the first computer-based decision support systems for practical site-specific fertilizer advice for the vegetable growing industry. The application of these advances had an important effect on the efficiency of crop production and the reduction of associated environmental impacts. Duncan continued to devise new models for nutrient and water use throughout the rest of his career and to explore ways of applying them in different areas of soil and crop science.
Understanding type VI secretion system effector activity and delivery in Acinetobacter baumannii

description: Acinetobacter baumannii is a bacterium that causes severe infections in hospitals. Increasingly, people are not getting the treatment they need, because this bacterium can be resistant to all known antibiotics. We were interested in studying the type VI secretion system, which is a weapon that bacteria use to kill other bacteria. This weapon resembles a bow that can shoot out poison arrows. We believe that understanding how this bow works and the different types of poisons it delivers could be useful for developing new drugs and overcoming antibiotic resistance.
Generic nodeless Larkin Ovchinnikov states due to singlet-triplet mixing

description: Larkin-Ovchinnikov (LO) states typically have a singlet-gap that vanishes along real-space lines. These real-space nodes lead to Andreev midgap states which can serve as a signature of LO pairing. We show that at these nodes, an odd-parity, spin-triplet component is always induced, leading to a nodeless LO phase. We find the two-dimensional weak coupling, clean limit s-wave phase diagram when this spin-triplet part is included. The triplet component is large and increases the stability of the FFLO phase. We also show that the spin-triplet contribution pushes the midgap states away from zero energy. Finally, we show how our results can be explained phenomenologically though Lifshitz invariants. These invariants provide a simple approach to understand the role of unconventional pairing states, spin-orbit coupling, and inhomogeneous mixed singlet-triplet states that are not due to a FFLO instability. We discuss our results in the context of organic superconductors.

description: Increasingly, elementary classroom teachers are being called to teach a myriad of subjects, including visual art, dance, and music. Preservice teachers must be prepared to teach and integrate multiple subjects. To that end, preservice teachers will need experiences in their preparation that help them to see connections across content areas and equip them with the knowledge and skills necessary to plan and teach meaningfully integrated lessons. This paper describes an exploratory experience that afforded preservice teachers an opportunity to explore the connections between music and mathematics during a hands-on drumming lesson.

description: We present Chandra detections of x-ray emission from the AGN in two giant Low Surface Brightness (LSB) galaxies, UGC 2936 and UGC 1455. Their x-ray luminosities are 1.8\times10^{42} ergs/s and 1.1\times10^{40} ergs/s respectively. Of the two galaxies, UGC 2936 is radio loud. Together with another LSB galaxy UGC 6614 (XMM archival data) both appear to lie above the X-ray-Radio fundamental plane and their AGN have black hole masses that are low compared to similar galaxies lying on the correlation. However, the bulges in these galaxies are well developed and we detect diffuse x-ray emission from four of the eight galaxies in our sample. Our results suggest that the bulges of giant LSB galaxies evolve independently of their halo dominated disks which are low in star formation and disk dynamics. The centers follow an evolutionary path similar to that of bulge dominated normal galaxies on the Hubble Sequence but the LSB disks remain unevolved. Thus the bulge and disk evolution are decoupled and so whatever star formation processes produced the bulges did not affect the disks.
