description: We introduce a new interacting particles model with blocking and pushing interactions. Particles evolve on the positive line jumping on their own volition rightwards or leftwards according to geometric jumps with parameter q. We show that the model involves a Pieri-type formula for the orthogonal group. We prove that the two extreme cases - q=0 and q=1 - lead respectively to a random tiling model studied by Borodin and Kuan and to a random matrix model.

description: Single and double electromagnetically induced transparency (EIT) in a medium, consisting of four-level atoms in the inverted-Y configuration, are discussed using mechanical and electrical analogies. A three coupled spring-mass system subject to damping and driven by an external force is used to represent the four-level atom mechanically. The equations of motion of this system are solved analytically, which revealed single and double EIT. On the other hand, three coupled RLC circuits are used, as the electrical analog, to explore and experimentally demonstrate single and double EIT. The simplicity of these two models makes this experiment appropriate for undergraduate students and easy to incorporate into a college physics laboratory.

description: The present article is devoted to studying the categorical relationships between the categories of Hopf trusses, weak twisted post-Hopf algebras, introduced by Wang (2023), and weak twisted relative Rota-Baxter operators. The latter objects are a generalisation of the relative Rota-Baxter operators defined by Li-Sheng-Tang (2024), where the Rota-Baxter condition is modified through a cocycle. Under certain conditions, this work shows that the three aforementioned categories are equivalent.
Intra-operative ultrasound-based augmented reality for laparoscopic surgical guidance
Creators: name: Singla, Rohit Kumar
Publisher: name: University of British Columbia
Year: 2017

description: Laparoscopic partial nephrectomy involves the complete resection of a kidney tumour, while minimizing healthy tissue excised, and under a time constraint before irreparable kidney damage occurs. The surgeon must complete this operation in a reduced sensory environment with poor depth perception, limited field of view, and little or no haptic feedback. For endophytic tumours (grows inwards), this is particularly difficult. In order to assist the surgeon, augmented reality can provide intra-operative guidance. Intra-operative ultrasound is low cost, non-ionising, and real-time. This has tremendous potential to guide the surgeon. This thesis details the development of three intra-operative augmented reality systems from a single framework, with augmentations all based on intra-operative ultrasound. The systems were all developed on the da Vinci Surgical System, using it as a development and testing platform. All systems leverage a single fiducial marker called the Dynamic Augmented Reality Tracker which can track the local surface and create a tumour-centric paradigm. A 3D ultrasound volume is reconstructed using a tracked ultrasound transducer. A tumour model is then extracted via manual segmentation of the volume. The three systems were developed and evaluated in simulated robot-assisted partial nephrectomies. The first system shows the feasibility of providing continuous ultrasound-based guidance during excision and achieves a system error of 5.1 mm RMS. Improving on this, the second system demonstrates clinically acceptable system error of 2.5 ± 0.5 mm. The second system significantly reduced healthy tissue excised from an average of 30.6 ± 5.5 cm³ to 17.5 ± 2.4 cm³ (p < 0.05) and reduced the depth from the tumor underside to cut from an average of 10.2 ± 4.1 mm to 3.3 ± 2.3 mm (p < 0.05). The third system is a novel intra-corporeal projector-based system that assists in determining the initial angle of resection. This system is evaluated in a surgeon study with a total of 32 simulated operations and addresses the limitations of conventional augmentations from the laparoscope's point of view. All three systems show their potential benefits in improving laparoscopic surgery with minimal additional hardware. With such image-guidance systems, the widespread adoption of laparoscopic surgery can be facilitated, improving patient care.

Unification of Dark Matter and Dark Energy in a Modified Entropic Force Model

description: In Verlinde's entropic force scenario of gravity, Newton's laws and Einstein equations can be obtained from the first pinciples and general assumptions. However, the equipartition law of energy is invalid at very low temperatures. We show clearly that the threshold of the equipartition law of energy is related with horizon of the universe. Thus, a one-dimension Debye (ODD) model in the direction of radius of the modified entropic force (MEF) maybe suitable in description of the accelerated expanding universe. We present a Friedmann cosmic dynamical model in the ODD-MEF framework. We examine carefully constraints on the ODD-MEF model from the Union2 compilation of the Supernova Cosmology Project (SCP) collaboration, the data from the observation of the large-scale structure (LSS) and the cosmic microwave background (CMB), i.e. SNe Ia+LSS+CMB. The combined numerical analysis gives the best-fit value of the model parameters $ζ\simeq10^{-9}$ and $Ω_{m0}=0.224$, with $χ_{min}^2=591.156$. The corresponding age of the universe agrees with the result of D. Spergel {\it et al.}\cite{Spergel2003} at 95% confidence level. The numerical result also yields an accelerated expanding universe without invoking any kind of dark energy. Taking $ζ(\equiv 2πω_D/H_0)$ as a running parameter associated with the structure scale $r$, we obtain a possible unified scenario of the asymptotic flatness of the radial velocity dispersion of spiral galaxies, the accelerated expanding universe and the Pioneer 10/11 anomaly in the entropic force framework of Verlinde.

description: The graph-theoretic Ramsey numbers are notoriously difficult to calculate. In fact, for the two-color Ramsey numbers $R(m,n)$ with $m,n\geq 3$, only nine are currently known. We present a quantum algorithm for the computation of the Ramsey numbers $R(m,n)$. We show how the computation of $R(m,n)$ can be mapped to a combinatorial optimization problem whose solution can be found using adiabatic quantum evolution. We numerically simulate this adiabatic quantum algorithm and show that it correctly determines the Ramsey numbers R(3,3) and R(2,s) for $5\leq s\leq 7$. We then discuss the algorithm's experimental implementation, and close by showing that Ramsey number computation belongs to the quantum complexity class QMA.

description: Landauer's erasure principle exposes an intrinsic relation between thermodynamics and information theory: the erasure of information stored in a system, S, requires an amount of work proportional to the entropy of that system. This entropy, H(S|O), depends on the information that a given observer, O, has about S, and the work necessary to erase a system may therefore vary for different observers. Here, we consider a general setting where the information held by the observer may be quantum-mechanical, and show that an amount of work proportional to H(S|O) is still sufficient to erase S. Since the entropy H(S|O) can now become negative, erasing a system can result in a net gain of work (and a corresponding cooling of the environment).

description: We study the locus of intermediate Jacobians of cubic threefolds within the moduli space of complex principally polarized abelian fivefolds, and its generalization to arbitrary genus - the locus of abelian varieties with a singular odd two-torsion point on the theta divisor. Assuming that this locus has expected codimension (which we show to be true for genus up to 5), we compute the class of this locus, and of is closure in the perfect cone toroidal compactification, in the Chow, homology, and the tautological ring. We work out the cases of genus up to 5 in detail, obtaining explicit expressions for the classes of the closures of the locus of products of an elliptic curve and a hyperelliptic genus 3 curve, in moduli of principally polarized abelian fourfolds, and of the locus of intermediate Jacobians in genus 5. In the course of our computation we also deal with various intersections of boundary divisors of a level toroidal compactification, which is of independent interest in understanding the cohomology and Chow rings of the moduli spaces.

description: Improving the speed and fidelity of quantum logic gates is essential to reach quantum advantage with future quantum computers. However, fast logic gates lead to increased leakage errors in superconducting quantum processors based on qubits with low anharmonicity, such as transmons. To reduce leakage errors, we propose and experimentally demonstrate two new analytical methods, Fourier ansatz spectrum tuning derivative removal by adiabatic gate (FAST DRAG) and higher-derivative (HD) DRAG, both of which enable shaping single-qubit control pulses in the frequency domain to achieve stronger suppression of leakage transitions compared to previously demonstrated pulse shapes. Using the new methods to suppress the $ef$-transition of a transmon qubit with an anharmonicity of -212 MHz, we implement $R_X(π/2)$-gates achieving a leakage error below $3.0 \times 10^{-5}$ down to a gate duration of 6.25 ns without the need for iterative closed-loop optimization. The obtained leakage error represents a 20-fold reduction in leakage compared to a conventional Cosine DRAG pulse. Employing the FAST DRAG method, we further achieve an error per gate of $(1.56 \pm 0.07)\times 10^{-4}$ at a 7.9-ns gate duration, outperforming conventional pulse shapes both in terms of error and gate speed. Furthermore, we study error-amplifying measurements for the characterization of temporal microwave control pulse distortions, and demonstrate that non-Markovian coherent errors caused by such distortions may be a significant source of error for sub-10-ns single-qubit gates unless corrected using predistortion.

description: Located along the western escarpment of the Superstition Mountains in Central Arizona, Hieroglyphic Canyon contains numerous petroglyphs associated with a perennial or nearly perennial spring, a large dry-laid wall, bedrock mortars, and artifact scatters. Evidence indicates that the area was used as a base camp by family groups of prehistoric and early historic Indians who hunted desert bighorn sheep and deer, and gathered wild plant foods. Although design elements depicting big game are predominant at the site, none of the animals show dart or arrow wounds. In addition, few of the animals are shown in wounded, dying, or dead positions. The absence of patterns normally associated with hunting magic raises several important questions about such interpretations at rock art sites. It is argued that many of the petroglyphs are the result of efforts to insure continued availability of big game animals in the area around the site, while other designs are associated with rituals and activities largely unrelated to hunting big game. This paper suggests that the site documents a gradual change in the subsistence patterns of the groups responsible for producing the petroglyphs. Results of the analysis of this large rock art site serve to emphasize the critical need to consider rock art within the context of the total site environment, both natural and cultural, and within a broader regional context. Further, rock art cannot be adequately understood unless the associated cultural features and artifacts form an integral part of the anthropological interpretation.

description: We report the final results of the Phase II SIMPLE measurements, comprising two run stages of 15 superheated droplet detectors each, the second stage including an improved neutron shielding. The analyses includes a refined signal analysis, and revised nucleation efficiency based on reanalysis of previously-reported monochromatic neutron irradiations. The combined results yield a contour minimum of σ_{p} = 4.2 x 10^-3 pb at 35 GeV/c^2 on the spin-dependent sector of WIMP-proton interactions, the most restrictive to date from a direct search experiment and overlapping for the first time results previously obtained only indirectly. In the spin-independent sector, a minimum of 3.6 x 10^-6 pb at 35 GeV/c^2 is achieved, with the exclusion contour challenging the recent CoGeNT region of current interest.

description: Wireless baseband processing (WBP) is a key element of wireless communications, with a series of signal processing modules to improve data throughput and counter channel fading. Conventional hardware solutions, such as digital signal processors (DSPs) and more recently, graphic processing units (GPUs), provide various degrees of parallelism, yet they both fail to take into account the cyclical and consecutive character of WBP. Furthermore, the large amount of data in WBPs cannot be processed quickly in symmetric multiprocessors (SMPs) due to the unpredictability of memory latency. To address this issue, we propose a hierarchical dataflow-driven architecture to accelerate WBP. A pack-and-ship approach is presented under a non-uniform memory access (NUMA) architecture to allow the subordinate tiles to operate in a bundled access and execute manner. We also propose a multi-level dataflow model and the related scheduling scheme to manage and allocate the heterogeneous hardware resources. Experiment results demonstrate that our prototype achieves $2\times$ and $2.3\times$ speedup in terms of normalized throughput and single-tile clock cycles compared with GPU and DSP counterparts in several critical WBP benchmarks. Additionally, a link-level throughput of $288$ Mbps can be achieved with a $45$-core configuration.

description: A low-background germanium spectrometer has been installed and is being operated in an ultra-low background shield (the Gator facility) at the Gran Sasso underground laboratory in Italy (LNGS). With an integrated rate of ~0.16 events/min in the energy range between 100-2700 keV, the background is comparable to those of the world's most sensitive germanium detectors. After a detailed description of the facility, its background sources as well as the calibration and efficiency measurements are introduced. Two independent analysis methods are described and compared using examples from selected sample measurements. The Gator facility is used to screen materials for XENON, GERDA, and in the context of next-generation astroparticle physics facilities such as DARWIN.

description: The Vaccine Adverse Event Reporting System (VAERS) was created by the Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) to receive reports about adverse events that may be associated with vaccines. No prescription drug or biological product, such as a vaccine, is completely free from side effects. Vaccines protect many people from dangerous illnesses, but vaccines, like drugs, can cause side effects, a small percentage of which may be serious. VAERS is used to continually monitor reports to determine whether any vaccine or vaccine lot has a higher than expected rate of events. Doctors and other vaccine providers are encouraged to report adverse events, even if they are not certain that the vaccination was the cause. Since it is difficult to distinguish a coincidental event from one truly caused by a vaccine, the VAERS database will contain events of both types. This dataset is downloaded from VAERS datasets and for more details on the dataset refer to the User Guide.

description: Over the course of the last seven to ten years, archaeologists working in different parts of the south central desert of Arizona have begun the documentation of Community Complexes. This is a general term for a range of phenomena which lie somewhere on the scale between community patterns and settlement patterns. This is a discussion of settlement structure rather than style, and not all researchers will be comfortable with this orientation. I readily violate and ignore many long standing culture-history distinctions, not to mention state and national boundaries. I argue that these Classic Period Community Complexes represent an infrastructure which was adopted across a wide portion of southern Arizona and New Mexico, cutting across a number of ceramic and architectural traditions, just as in prehistoric times it undoubtedly cut across a number of ethnic and social traditions. What is important is that the people of these southern deserts adopted this infrastructure, and there is a very definite northern limit to its use as an organizational scheme. It is important to understand why this structure developed, how it functioned, why it did not extend further north, and why it ceased to operate at about A.D. 1400.
Charge-selective transparent conductors for solution-processed organic solar cells
Creators: name: Rahmanian, Rowshan
Publisher: name: University of British Columbia

description: Organic solar cells (OSCs) become increasingly popular for harvesting solar energy, due to their potential for low-cost manufacturing and mechanical flexibility. As the efficiency of laboratory-scale devices increases, developing materials and processes that would enable low-cost roll-to-roll fabrication of such devices gains increasing research interest. In order to promote OSCs as a viable substitute for silicon-based solar cells, it is necessary to synthesize materials that can offer high performances, roll-to-roll processability, and potential for flexibility, via processes that are scalable, and do not rely heavily on costly fabrication conditions, such as high temperature, vacuum processing, or inert atmospheres. This research is focused on two related aspects within this goal. The first part of the research concerns the fabrication of highly stretchable transparent conductive electrodes (TCEs) as replacement for conventional indium tin oxide (ITO) TCEs. Sparse meshes of metallized polyacrylonitrile nanofibers (NFs) fabricated via the scalable electrospinnig method are used to realize TCEs with performances comparable to ITO electrodes (sheet resistance, Rs, of 155 Ω/□, with transparency, T, of 95%) and with unprecedented electromechanical stretchability (only 56% increase in resistance at 100% strain). Furthermore, by incorporating the metallized NFs into matrices of solution-processed, charge-selective layers, composite charge-selective TCEs are fabricated. Annealed at the appropriate temperature, these charge-selective TCEs achieve performances superior to ITO and on a par with the uncoated NF TCEs. Using ZnO as the matrix, electron-selective composite TCEs with Rs = 23 Ω/□ at T = 95% are fabricated. Using MoO₃, hole-selective TCEs with Rs = 35.5 Ω/□ at T = 94% are obtained. The second part of the research, involves the fabrication of OSCs using a scalable, low-temperature spray-coating process in air. By employing an accelerated air drying post-deposition stage, we were able to achieve large-area pinhole-free coatings of P3HT:PCBM layers with sub-nanometer surface roughness, through single-pass spray-coating at 25 °C substrate temperature. OSCs fabricated in air through this process, achieve power conversion efficiencies up to 2.57%, comparable to the reference devices fabricated via spin-coating in nitrogen atmosphere. The introduced process is successfully used to fabricate fully-sprayed, as well as large-area OSCs.

description: During last two decades it has been discovered that the statistical properties of a number of microscopically rather different random systems at the macroscopic level are described by {\it the same} universal probability distribution function which is called the Tracy-Widom (TW) distribution. Among these systems we find both purely methematical problems, such as the longest increasing subsequences in random permutations, and quite physical ones, such as directed polymers in random media or polynuclear crystal growth. In the extensive Introduction we discuss in simple terms these various random systems and explain what the universal TW function is. Next, concentrating on the example of one-dimensional directed polymers in random potential we give the main lines of the formal proof that fluctuations of their free energy are described the universal TW distribution. The second part of the review consist of detailed appendices which provide necessary self-contained mathematical background for the first part.

description: We present parallel algorithms for constructing and traversing sparse octrees on graphics processing units (GPUs). The algorithms are based on parallel-scan and sort methods. To test the performance and feasibility, we implemented them in CUDA in the form of a gravitational tree-code which completely runs on the GPU.(The code is publicly available at: http://castle.strw.leidenuniv.nl/software.html) The tree construction and traverse algorithms are portable to many-core devices which have support for CUDA or OpenCL programming languages. The gravitational tree-code outperforms tuned CPU code during the tree-construction and shows a performance improvement of more than a factor 20 overall, resulting in a processing rate of more than 2.8 million particles per second.

description: Using large scale real-time lattice simulations, we calculate the baryon asymmetry generated at a fast, cold electroweak symmetry breaking transition. CP-violation is provided by the leading effective bosonic term resulting from integrating out the fermions in the Minimal Standard Model at zero temperature, and performing a covariant gradient expansion [1]. This is an extension of the work presented in [2]. The numerical implementation is described in detail, and we address issues specifically related to using this CP-violating term in the context of Cold Electroweak Baryogenesis. The results support the conclusion of [2], that Standard Model CP-violation may be able to reproduce the observed baryon asymmetry in the Universe in the context of Cold Electroweak Baryogenesis.

Finding QWAMQWƏMT : re-storying post-secondary education for Aboriginal people
Creators: name: Chenoweth, John Alexander
Publisher: name: University of British Columbia
Year: 2017

description: Aboriginal people face numerous challenges in post-secondary education. In this research, I identify the shortcomings evidenced in the educational system in relation to Indigenous identity and epistemology, external Aboriginal policy, Indigenous control of education, and Indigenous community. Additionally, I examine the realities of Aboriginal people who have paused-out and then return to school, and what factors influence their successful educational experiences. I use a syilx Indigenous systems-based pedagogy embedded in a traditional story as my primary theoretical framework. The Four Chiefs story is a syilx Okanagan construct that serves as the model with four oppositional concepts to address community-based questions. This is the basis of enowkinwixw, a syilx-based governance decision-making process. I survey 60 students from across the province who attended the Nicola Valley Institute of Technology. Questions relate to a student’s experience in the K-12 system, the transition to post-secondary, and actualities while attending NVIT. Analysis indicates that shortcomings in the educational system relate to a lack of acknowledgement of Indigenous identity. Aboriginal students return to school for economic reasons and concern for future generations. A balance of encouragement and support from outside and within the educational system lead to a fulfilling educational experience. Without the Indigenous Community realizing how important it is to take control and reorganize how it re-imagines the educational experience of its Aboriginal students, nothing will change. This Study demonstrates that the Four Chiefs model is an appropriate and useful tool to re-imagine Aboriginal post-secondary education. It is a holistic approach to illuminate the many educational challenges faced by Indigenous students as part of their Indigenous community.

description: Diabetes mellitus (DM) predisposes patients to vascular complications. Retinal images and vasculature reflect the body's micro- and macrovascular health. They can be used to diagnose DM complications, including diabetic retinopathy (DR), neuropathy, nephropathy, and atherosclerotic cardiovascular disease, as well as forecast the risk of cardiovascular events. Artificial intelligence (AI)-enabled systems developed for high-throughput detection of DR using digitized retinal images have become clinically adopted. Beyond DR screening, AI integration also holds immense potential to address challenges associated with the holistic care of the patient with DM. In this work, we aim to comprehensively review the literature for studies on AI applications based on retinal images related to DM diagnosis, prognostication, and management. We will describe the findings of holistic AI-assisted diabetes care, including but not limited to DR screening, and discuss barriers to implementing such systems, including issues concerning ethics, data privacy, equitable access, and explainability. With the ability to evaluate the patient's health status vis a vis DM complication as well as risk prognostication of future cardiovascular complications, AI-assisted retinal image analysis has the potential to become a central tool for modern personalized medicine in patients with DM.
