description: The Horton and Tokunaga branching laws provide a convenient framework for studying self-similarity in random trees. The Horton self-similarity is a weaker property that addresses the principal branching in a tree; it is a counterpart of the power-law size distribution for elements of a branching system. The stronger Tokunaga self-similarity addresses so-called side branching. The Horton and Tokunaga self-similarity have been empirically established in numerous observed and modeled systems, and proven for two paradigmatic models: the critical Galton-Watson branching process with finite progeny and the finite-tree representation of a regular Brownian excursion. This study establishes the Tokunaga and Horton self-similarity for a tree representation of a finite symmetric homogeneous Markov chain. We also extend the concept of Horton and Tokunaga self-similarity to infinite trees and establish self-similarity for an infinite-tree representation of a regular Brownian motion. We conjecture that fractional Brownian motions are also Tokunaga and Horton self-similar, with self-similarity parameters depending on the Hurst exponent.

Countering Trusting Trust through Diverse Double-Compiling

description: An Air Force evaluation of Multics, and Ken Thompson's famous Turing award lecture "Reflections on Trusting Trust," showed that compilers can be subverted to insert malicious Trojan horses into critical software, including themselves. If this attack goes undetected, even complete analysis of a system's source code will not find the malicious code that is running, and methods for detecting this particular attack are not widely known. This paper describes a practical technique, termed diverse double-compiling (DDC), that detects this attack and some compiler defects as well. Simply recompile the source code twice: once with a second (trusted) compiler, and again using the result of the first compilation. If the result is bit-for-bit identical with the untrusted binary, then the source code accurately represents the binary. This technique has been mentioned informally, but its issues and ramifications have not been identified or discussed in a peer-reviewed work, nor has a public demonstration been made. This paper describes the technique, justifies it, describes how to overcome practical challenges, and demonstrates it.

Single-cell analytics for phospho flow cytometry reveals dynamic interactions between molecular pathways
Creators: name: Huang, Yue
Publisher: name: University of British Columbia
Year: 2021

description: Quantitative analysis of large single-cell measures acquired by phospho flow cytometry typically involves establishing inclusion gate thresholds and combining measures from accepted cells into a single median metric. Though this analysis method is simple, it overlooks the heterogeneity of cell populations and there could be information missing from the single-cell level. Here, we have formulated approaches that can recognize the heterogeneity and extract additional information involving dose-response and interactions between multiple molecules from phospho flow cytometry datasets. Using phospho flow multiplexed sampling of cell physical features, and primary antibodies against protein markers, including GAPDH as a protein expression control, HA tag as an exogenous gene/variant transfection measurement, and 8 antibodies detecting the activation (phosphorylation) states of 8 proteins within conserved molecular pathways, two panels of phospho-specific antibodies were used simultaneously for multiplexed measures in the same cells. Our approach involves single-cell standardization, fitting loess regression, identifying linear domains in dose-response plots, building linear mixed-effects models, and multi-dimensional analyses to detect interactions between phosphorylated protein markers. We demonstrate the utility of this approach by expressing wild-type and 5 variants (4A, D268E, Y138L, P38H, G129E) of PTEN on 8 markers of molecular pathways downstream of PTEN, and we also expressed RHEB WT testing its impact on markers in the shared associated pathways. We succeeded in differentiating subtypes of PTEN loss-of-function variants and were able to predict that PTEN P38H is a loss-of-lipid-phosphatase-function variant. We were also able to infer that pAKT, p4EBP1, pS6, and pCREB are all downstream targets of PTEN regulation while pAKT is between PTEN and p4EBP1, pS6, or pCREB. In conclusion, our results demonstrate dose response and molecular pathway interactions unavailable from reducing population data to single values, and our approach manifests strong promise in variant function measurement and molecular signaling pathway inference.
Light scattering from a magnetically tunable dense random medium with weak dissipation : ferrofluid

description: We present a semi-phenomenological treatment of light transmission through and its reflection from a ferrofluid, which we regard as a magnetically tunable system of dense random dielectric scatterers with weak dissipation. Partial spatial ordering is introduced by the application of a transverse magnetic field that superimposes a periodic modulation on the dielectric randomess. This introduces Bragg scattering which effectively enhances the scattering due to disorder alone, and thus reduces the elastic mean free path towards Anderson localization. Our theoretical treatment, based on invariant imbedding, gives a simultaneous decrease of transmission and reflection without change of incident linear polarisation as the spatial order is tuned magnetically to the Bragg condition, namely the light wave vector being equal to half the Bragg vector (Q). Our experimental observations are in qualitative agreement with these results. We have also given expressions for the transit (sojourn) time of light and for the light energy stored in the random medium under steady illumination. The ferrofluid thus provides an interesting physical realization of effectively a "Lossy Anderson-Bragg" (LAB) cavity with which to study the effect of the interplay of spatial disorder, partial order and weak dissipation on light transport. Given the current interest in propagation, optical limiting and storage of light in ferrofluids, the present work seems topical.

description: We consider Einstein-Maxwell-Kalb-Ramond gravity-matter system in bulk space-time interacting self-consistently with two (widely separated) codimension-one electrically charged lightlike branes. The lightlike brane dynamics is explicitly given by manifestly reparametrization invariant world-volume actions in two equivalent dual to each other formulations (Polyakov-type and Nambu-Goto-type ones) proposed in our previous work. We find an explicit solution of the pertinent Einstein-Maxwell-Kalb-Ramond-lightlike-brane equations of motion describing a "two-throat" wormhole-like space-time consisting of a "left" compactified Bertotti-Robinson universe connected to a "middle" non-compact Reissner-Nordstroem-de-Sitter space-time region, which in turn is connected to another "right" compactified Bertotti-Robinson universe. Each of the lightlike branes automatically occupies one of the "throats", so that they dynamically induce a sequence of spontaneous space-time compactification/decompactification transitions.

description: Let (M,g) be a three-dimensional smooth compact Riemannian manifold such that all geodesics are simple and closed with a common minimal period, such as the 3-sphere S^3 with canonical metric. In this work the global well-posedness problem for the quintic nonlinear Schrödinger equation i\partial_t u+Δu=\pm|u|^4u, u|_{t=0}=u_0 is solved for small initial data u_0 in the energy space H^1(M), which is the scaling-critical space. Further, local well-posedness for large data, as well as persistence of higher initial Sobolev regularity is obtained. This extends previous results of Burq-Gérard-Tzvetkov to the endpoint case.

By using edge recognition the method is designed to locate and identify small features when the STM tip is far above the surface allowing for crash-free search and navigation. The method can be implemented in any STM environment even at low temperatures and in strong magnetic field, with minimal or no hardware modifications.

QCD Corrections to Flavor Changing Neutral Coupling Mediated Rare Top Quark Decays

description: Recently we have presented an analysis of flavor changing neutral coupling mediated radiative top quark decays at next-to-leading order in QCD. In the present paper we provide the details of the calculation of QCD corrections to t-> q gamma and t-> q Z decays within the effective theory approach including operator mixing. In particular, we calculate virtual matrix element corrections and the corresponding bremsstrahlung contributions. In the case of t-> q gamma we study the effects of kinematic cuts on the extracted branching ratios. Analytical formulae are given at all stages of the calculation. We find that the t-> q gamma decay can be used to probe also the effective operators mediating t-> q g processes, since these can naturally contribute 10% or more to the radiative decay, given typical experimental cuts on the decay kinematics at hadron colliders. Conversely, we argue that any positive experimental signal of the t-> q g process would indicate a natural lower bound on t-> q gamma decay rate.

title: Unity within Diverse Multiplicity: masonry, method, and analogy in Byzantine architecture

description: Architecture is a mute medium. It presents neither pictures nor words. Its power is as a medium in which the whole human body is immersed. We spend almost all our time in buildings, yet in everyday life we are usually unconscious of its continuous communication through its forms and materials. This research proposes that load-bearing masonry architecture offers an experience of theology to its builders and visitors. Yet how can one prove this if historical mason-builders never wrote this down? How can one show that building could be a theological medium with a contemplation as potent as any rosary and a mystagogy as valid as any pilgrimage, in harmony with the natu- ral world, and a journey to divine unity? This thesis focuses on the masonry church of Hagia Sophia, Thessaloniki by comparing the three categories of ritual, iconography, and masonry architecture. It is a unique example of a Byz- antine cross-domed church, since it still retains its essential iconography, and in it the early Christian liturgies continue to be celebrated. Primary theological texts from Dionysios the (pseudo) Areopagite to Maxi- mos the Confessor, as well as 6th century literary ekphraseis (eulogies) to other Hagia Sophias, guide this work of comparison and translation. In methodology, two modern philosophers are referenced, Michel Foucault and Gaston Ba- chelard, to illustrate aspects of the above theologians's work for the contempo- rary reader. This thesis translates between these three categories using theoria (theory) and mystagogia, (mystagogy) seeking to infer a masons' guided (mystagogic) method, whereby an intangible, timeless metaphysics could be communicated by the material architecture. This exercise in translation from one medium of expression to another, and from one category of knowledge to another, begins to uncover a language of architectural theory that harmonizes a sense of 'unity within diverse multiplicity' with the material environment. The methodology puts the focus on hands-on experience which could be transferrable to modern masonry and even sustainable technologies, as healing for the individual and the community.

description: The top quark sector is almost decoupled from lighter quark generations due to the fact that $V_{tb}\approx$~1. The current experimental measurements of $V_{tb}$ are compatible with the Standard Model expectations but are still dominated by experimental uncertainties. In this manuscript, a revision of the experimental methods used to measure $V_{tb}$ is given, and a simple method to probe heavy flavor content fraction of top quark events, $R=B(t\rightarrow Wb)/B(t\rightarrow Wq)$, is presented and discussed. Prospects for the measurements at the Large Hadron Collider based on generator level simulations are outlined.

description: We present several applications of the layered electron gas model to electron energy loss spectroscopy of free-standing films consisting of $N$ graphene layers in a scanning transmission electron microscope. Using a two-fluid model for the single-layer polarizability, we discuss the evolution of high-energy plasmon spectra with $N$, and find good agreement with the recent experimental data for both multi-layer graphene with $N<10$, and thick slabs of graphite. Such applications of these analytical models help shed light on several features observed in the plasmon spectra of those structures, including the role of plasmon dispersion, dynamic interference in excitations of various plasmon eigenmodes, as well as the relevance of the bulk plasmon bands, rather than surface plasmons, in classifying the plasmon peaks.

description: In this work, criteria for analyzing game engines were identified to choose an engine as a tool for indie development. The Unity game engine was chosen for development, and a general overview of the engine is provided. The paper describes procedural content generation in games, specifically procedural level generation. Existing methods of procedural level generation are examined (cellular automata method, binary space partitioning method). A method is proposed for combining and modifying existing algorithms to create cave-levels for the game. As a result, a game application is developed for mobile Android devices with customizable procedural level generation, and testing of the games functionality on Android devices of various configurations is performed using the Android Virtual Device emulation program.
Could the Magellanic Clouds be tidal dwarves expelled from a past-merger event occurring in Andromeda?

description: The Magellanic Clouds are often considered as outliers in the satellite system of the Milky Way because they are irregular and gas-rich galaxies. From their large relative motion, they are likely from their first pass near the Milky Way, possibly originating from another region of the Local Group or its outskirts. M31 could have been in a merger stage in its past and we investigate whether or not the Large Magellanic Cloud could have been a tidal dwarf expelled during this event. Such an hypothesis is tested in the frame of present-day measurements and uncertainties of the relative motions of LMC and M31. Our method is to trace back the LMC trajectory using several thousands of different configurations that sample the corresponding parameter space. We find several configurations that let LMC at 50 kpc from M31, 4.3 to 8 Gyrs ago, depending on the adopted shape of the Milky Way halo. For all configurations, the LMC velocity at such a location is invariably slightly larger than the escape velocity at such a radius. The preferred solutions correspond to a spherical to prolate Milky Way halo, predicting a transversal motion of M31 of less than 107 km/s and down to values that are close to zero. We conclude that from present-day measurements, Magellanic Clouds could well be tidal dwarves expelled from a former merger events occurring in M31.

The theory is used to compute the nonlinear response of the film to a static or low-frequency external electric field and to investigate the role of boundary conditions imposed on the metal surface. We find that the sign and magnitude of the nonlinear polarizability depends dramatically on the type of boundary condition used.

description: A quantum field model for Dirac-like tachyons respecting a frame-dependent interpretation rule, and thus inherently breaking Lorentz invariance, is defined. It is shown how the usual paradoxa ascribed to tachyons, instability and acausality, are resolved in this model, and it is argued elsewhere that Lorentz symmetry breaking is necessary to permit perturbative renormalizability and causality. Elimination of negative-normed states results in only left-handed particles and right-handed antiparticles, suitable for describing the neutrino. In this context the neutron beta decay spectrum is calculated near the end point for large, but not ultrarelativistic preferred frame speed, assuming a vector weak interaction vertex.

Early adolescents' perspectives of caring student-teacher relationships : a mixed methods approach
Creators: name: Whitehead, Jenna
Publisher: name: University of British Columbia
Year: 2021

description: For decades, research has documented the importance of caring student-teacher relationships in fostering students’ healthy development. Less attention has been paid, however, to investigating specific qualities of caring student-teacher relationships from the perspective of early adolescents in middle school. Three studies were conducted to address this gap. Study 1 presents the development and validation of the Caring Student-Teacher Relationship (CSTR) scale. An exploratory factor analysis (EFA) was conducted on data from 222 sixth and seventh grade students and a two-factor solution was found: Teacher Support and Attunement and Caring Teacher Qualities. Analyses revealed that the two factors were related in expected directions to existing measures of teacher support, to student and teacher-rated student adjustment, and to teachers’ reports of mindfulness and burnout. Study 2 explored 199 sixth and seventh grade students’ written responses to the question “What are three things that teachers do to show they care?” via a qualitative content analysis. Findings revealed 19 themes; 18 of which were grouped into one of three thematic categories associated with mindful teaching: Calm, Clear, and Kind, and one General Teaching theme. Most students’ responses comprised Kind and Clear themes. Girls’ responses were more likely to include Clear themes compared to boys. Study 3 investigated the congruence of student and teacher reports of their dyadic relationship and the relation of this congruence to students’ school functioning, prosociality, and well-being. A cluster analysis of 219 sixth and seventh graders and their teachers produced four profiles based on the consistency between students’ and teachers’ perceptions of their relationship quality: Congruent–Negative, Congruent–Positive, Incongruent–Student Positive/Teacher Negative, Incongruent–Student Negative/Teacher Positive. Students in the Congruent-Positive group were rated highest on both self- and teacher-reported dimensions of prosociality in contrast to students in other groups. Moreover, groups in which students rated the student-teacher relationship positive regardless of teachers’ ratings of the relationship were highest on school and well-being dimensions. Findings from this research has implications for understanding the nature of student-teacher relationships in early adolescence, particularly in middle school, and the association of these relationships with students’ overall functioning.

Schur-finiteness and endomorphisms universally of trace zero via certain trace relations

description: We provide a sufficient condition that ensures the nilpotency of endomorphisms universally of trace zero of Schur-finite objects in a category of homological type, i.e., a Q-linear tensor category with a tensor functor to super vector spaces. This generalizes previous results about finite-dimensional objects, in particular by Kimura in the category of motives. We also present some facts which suggest that this might be the best generalization possible of this line of proof. To get the result we prove an identity of trace relations on super vector spaces which has an independent interest in the field of combinatorics. Our main tool is Berele-Regev's theory of Hook Schur functions. We use their generalization of the classic Schur-Weyl duality to the "super" case, together with their factorization formula.
Using Indigenous legal processes to strengthen Indigenous jurisdiction : Squamish Nation land use planning and the Squamish Nation assessment of the Woodfibre liquefied natural gas projects
Creators: name: Sankey, Jennifer M.
Publisher: name: University of British Columbia
Year: 2021

description: This dissertation examines how Squamish Nation has created its own legal processes in land use planning and environmental assessment to strengthen its jurisdiction over land, water, and resources in Squamish Nation Territory. It provides a case study of Squamish Nation’s development of the Xay Temíxw Land Use Plan for Forests and Wilderness of Squamish Nation Traditional Territory, its negotiation of an agreement on land use planning with the Province of British Columbia, and its creation of an environmental assessment process (the Squamish Process) to assess liquefied natural gas (LNG) projects being proposed in Howe Sound. The case study reveals Squamish Nation’s motivations for developing the processes; the type of community engagement it used; the perspectives, values, and laws Squamish members brought to their deliberations in the processes; and how Squamish Nation made its final decisions. It illuminates how these processes articulate Squamish legal principles to wider Canadian audiences through the plans, reports and agreements that have emerged from the processes. It also shows how these processes placed pressure on the state, as well as third parties, and how these pressures led to shifts in state/proponent practices and behaviours that have strengthened Squamish Nation jurisdiction. The research suggests that successful implementation of the doctrine of free, prior, and informed consent (FPIC) will be better achieved if Canadian governments shift their focus away from narrow judicial interpretations of the duty to consult, and toward Indigenous-led processes for establishing consent, articulated through Indigenous legal orders.

description: We explore the use of Virtual Reality as a way to simulate field studies via what is known as Virtual Field Studies. This is particularly relevant when inviting participants to the lab is not feasible, or in the case of our work to simulate locomotion in crowded streets from the safety of the lab. We rely on this to assess the effects of four different cues in normalising gait performance in a simulated environment: two baselines from literature (visual and haptic) that have been traditionally explored in the context of a controlled lab environment, and two novel haptic cues that combine temporal and spatial feedback. We compare these in a holistic manner for the first time, capturing not only gait and gaze performance, but usability, perceived workload, and participant preference. Our haptic baseline performed according to the results described in the literature, and together with participants' gaze behaviour and sense of embodiment we start to validate Virtual Field Studies in this domain. We further report that the haptic baseline was the preferred cue by participants, and led to an overall better performance. We conclude with our implementation of GaitWear, a smart watch application that produces this haptic baseline on the fly.

description: On 17 January 2005 two fast coronal mass ejections were recorded in close succession during two distinct episodes of a 3B/X3.8 flare. Both were accompanied by metre-to-kilometre type-III groups tracing energetic electrons that escape into the interplanetary space and by decametre-to-hectometre type- II bursts attributed to CME-driven shock waves. A peculiar type-III burst group was observed below 600 kHz 1.5 hours after the second type III group. It occurred without any simultaneous activity at higher frequencies, around the time when the two CMEs were expected to interact. We associate this emission with the interaction of the CMEs at heliocentric distances of about 25 R\odot. Near-relativistic electrons observed by the EPAM experiment onboard ACE near 1 AU revealed successive particle releases that can be associated with the two flare/CME events and the low-frequency type-III burst at the time of CME interaction. We compare the pros and cons of shock acceleration and acceleration in the course of magnetic reconnection for the escaping electron beams revealed by the type III bursts and for the electrons measured in situ.

Depletion of CCS in a Candidate Warm-Carbon-Chain-Chemistry Source L483

description: We have carried out an observation of the CCS ($J_{N}$=2$_{1}-$1$_{0}$) line with the Very Large Array in its D-configuration toward a protostellar core L483 (IRAS~18140$-$0440). This is a candidate source of the newly found carbon-chain rich environment called "Warm-Carbon-Chain-Chemistry (WCCC)", according to the previous observations of carbon-chain molecules. The CCS distribution in L483 is found to consist of two clumps aligned in the northwest-southeast direction, well tracing the CCS ridge observed with the single-dish radio telescope. The most remarkable feature is that CCS is depleted at the core center. Such a CCS distribution with the central hole is consistent with those of previously observed prestellar and protostellar cores, but it is rather unexpected for L483. This is because the distribution of CS, which is usually similar to that of CCS, is centrally peaked. Our results imply that the CCS ($J_{N}$=2$_{1}-$1$_{0}$) line would selectively trace the outer cold envelope in the chemically less evolved phase that is seriously resolved out with the interferometric observation. Thus, it is most likely that the high abundance of CCS in L483 relative to the other WCCC sources is not due to the activity of the protostar, although it would be related to its younger chemical evolutionary stage, or a short timescale of the prestellar phase.

description: The primary goal of this paper is to provide the evidence that can either prove or falsify the hypothesis that dark matter in the Galactic halo can clump into stellar-mass compact objects. If such objects existed, they would act as lenses to external sources in the Magellanic Clouds, giving rise to an observable effect of microlensing. We present the results of our search for such events, based on the data from the second phase of the OGLE survey (1996-2000) towards the SMC. The data set we used is comprised of 2.1 million monitored sources distributed over an area of 2.4 square degrees. We found only one microlensing event candidate, however its poor quality light curve limited our discussion on the exact distance to the lensing object. Given a single event, taking the blending (crowding of stars) into account for the detection efficiency simulations, and deriving the HST-corrected number of monitored stars, the microlensing optical depth is tau=(1.55+-1.55)10e-7. This result is consistent with the expected SMC self-lensing signal, with no need of introducing dark matter microlenses. Rejecting the unconvincing event leads to the upper limit on the fraction of dark matter in the form of MACHOs to f<20 per cent for deflectors' masses around 0.4 Msun and f<11 per cent for masses between 0.003 and 0.2 Msun (95 per cent confidence limit). Our result indicates that the Milky Way's dark matter is unlikely to be clumpy and form compact objects in the sub-solar-mass range.

description: We performed a highly sensitive search for magnetic fields on a large set of HgMn stars. With the aid of a new polarimeter attached to the HARPS spectrometer at the ESO 3.6m-telescope, we obtained high-quality circular polarization spectra of 41 single and double HgMn stars. Using a multi-line analysis technique on each star, we co-added information from hundreds of spectral lines resulting in significantly greater sensitivity to the presence of magnetic fields, including very weak fields. For the 47 individual objects studied, including 6 components of SB2 systems, we do not detect any magnetic fields at greater than the 3 sigma level. The lack of detection in the circular polarization profiles indicates that if strong fields are present on these stars, they must have complex surface topologies. For simple global fields, our detection limits imply upper limits to the fields present of 2-10 Gauss in the best cases. We conclude that HgMn stars lack large-scale magnetic fields, typical for spotted magnetic Ap stars, sufficient to form and sustain the chemical spots observed on HgMn stars. Our study confirms that in addition to magnetically altered atomic diffusion, there exists another differentiation mechanism operating in the atmospheres of late-B main sequence stars which can compositional inhomogeneities on their surfaces.

description: A system of a particle and a harmonic oscillator, which have pure point spectrum if uncoupled, is known to acquire absolutely continuous spectrum when the particle and the oscillator are coupled by a sufficiently strong point interaction. Here the simple dynamical mechanism underlying this phenomenon is exposed. The energy of the oscillator is proven to exponentially diverge in time, while the spatial probability distribution of the particle collapses into a delta function in the interaction point. On account of this result, a generalized model with many oscillators which interact with the particle at different points is argued to provide a formal model for approximate measurement of position, and collapse of wave packets.
