description: The most important problem is to built shelters for the disaster victims and urgent buildings like hospitals, crisis administration centers, schools, storages for the materials etc. after the earthquakes on the disaster sites. In this thesis, it will be tried to find fast solutions for the need for housing of the victims. Because it takes time to build buildings for the victims using conventional constructions with reinforced concrete or steel structural materials. Waste of time can risk many people-s life in disaster conditions. However, the most important outcomes of the earthquake are not only the damages in settlements, but also the damages at the transportation systems, electricity systems of the accommodation units and at the power plants and refineries. Because of these reasons, this thesis aims to propose foldable, deployable or mechanical fabric structures in the case of -small tent- without the need for energy. The advantages of such systems are, easy installation without special experts, portable feature, the ease of packaged and the ease of transport. Also, they are light to transport with helicopter or airplanes. As a result the development of such systems will be useful in the earthquake disaster conditions.

description: We find that it is possible to increase sensitivity to low energy physics in a third or fourth DUNE-like module with careful controls over radiopurity and targeted modifications to a detector similar to the DUNE Far Detector design. In particular, sensitivity to supernova and solar neutrinos can be enhanced with improved MeV-scale reach. A neutrinoless double beta decay search with $^{136}$Xe loading appears feasible. Furthermore, sensitivity to Weakly-Interacting Massive Particle (WIMP) Dark Matter (DM) becomes competitive with the planned world program in such a detector, offering a unique seasonal variation detection that is characteristic for the nature of WIMPs.

Verb-noun combinations and their functions in job cover letters : a comparison across three corpora
Creators: name: Everest, Terri Josephine
Publisher: name: University of British Columbia
Year: 2022

description: Words are particular about the company they keep, so educators have long endeavored to crack the collocational code, accelerating SLA. This endeavor is supported by powerful digital tools enabling corpus analysis. Many academic genres have thus been analyzed, phrases linked to moves (functions), and writing roadmaps developed. However, fewer professional genres, notably the job cover letter, have garnered attention. Studies in this “occluded genre” (Swales, 1996, p. 46) usually feature small corpora by EFL writers sharing one L1. Instead, this cross-sectional study compares three English cover letter corpora in an ESL environment: a balanced corpus with samples from books; another NES one; and a third by Canadian immigrants with diverse L1s. After a pilot study, three questions were posed. One categorized move fulfillment by genre-specific verb-noun combinations (VNCs); another identified learners’ lexico-grammatical VNC errors; and a third quantified fulfillment by VNCs versus other lexical means, also identifying obligatory versus optional moves. CLAWS4 POS-tagged corpora, analyzed in Excel (and secondarily AntConc) using Sinclair’s node-collocate approach (1991) with a 4-4 span for VNCs. Lemmatized VNCs were extracted semi-automatically; MI and t- scores determined significance (Hunston, 2002), with t- scores ranking VNCs. Using Swalesian and Bhatian ESP genre analysis, VNCs were categorized into eight moves, adapting Upton and Connor’s (2001) framework. Error analysis addressed verbs, nouns, and other infelicities, paralleling others (e.g., Nesselhauf, 2005). VNCs with (borderline) significance, whether genre-specific or another category (e.g., field-specific) semi-automatically populated Excel sheets in a case (letter) by variable (move) format. Moves unfulfilled by genre-specific VNCs were examined using “intuitive notion of topic” (Brown & Yule, 1983, p. 69) to determine which other means, including structural elements, were instrumental. Regarding outcomes, learners employed more colloquial VNCs in moves. Determiner, verb tense/aspect, and preposition errors predominated. While over half the learners’ genre- specific VNCs were correct, many were fixed phrases. VNCs were integral in move fulfillment; other means still complemented or replaced them. More moves appeared obligatory than optional and some evolving. Learners rarely fulfilled some, perhaps lacking genre awareness. This study concludes with pedagogical recommendations. Future avenues are addressed and facilitated by my corpora, archived at cIRcle.

description: The present work focuses on the development of a lightweight membrane billboard tower as an alternative to the existing outdoor advertising means, an alternative which integrates into the general architecture of a city and enriches the urban aesthetics. In order to underline its utility for the community and draw a comprehensive image of this project, the author has chosen an approach which takes into account several perspectives and has analyzed the project as a result of these perspectives. To this end, the project has been located on a time axis and on a historical background. Further on, the author has placed the lightweight membrane billboard tower in an existing location, the characteristics of which have determined the form, the building solution as well as the possibilities which arise from these. Last but not least, since every project needs financing, an outlook of the possibilities that could be taken into account by a possible investor is given.
Pseudo-Dirac Dark Matter Leaves a Trace

description: Pseudo-Dirac Dark Matter is a viable type of dark matter which originates from a new Dirac fermion whose two Weyl states get slightly split in mass by a small Majorana term. The decay of the heavier to the lighter state naturally occurs over a detectable length scale. Thus, whenever pseudo-Dirac Dark Matter is produced in a collider, it leaves a clear trace: a visible displaced vertex in association with missing energy. Moreover, pseudo-Dirac Dark Matter behaves Dirac-like for relic abundance and Majorana-like in direct detection experiments: it has efficient s-wave annihilations but it lacks of dangerous vector interactions with the quarks in the nuclei. We provide a general treatment using an effective field theory approach, then specializing to the supersymmetric situation of a pseudo-Dirac Bino. The dark matter mass and the mass splitting can be extracted from measurements of the decay length and the invariant mass of the products, even in presence of missing energy.

Oxygen, carbon dioxide and ammonia exchange in the gastrointestinal tract of teleost fish
Creators: name: Jung, Hyewon
Publisher: name: University of British Columbia
Year: 2022

description: The gastrointestinal tract (GIT) of teleost fish is a multifunctional organ system involved in digestion, assimilation of nutrients, immune responses, neuroendocrine functions and osmoregulation. Many of these processes have implications for gas exchange, acid-base regulation and ion regulation. However, there is a current lack of knowledge on the basic physiology of the three respiratory gases - oxygen, carbon dioxide and ammonia - in the GIT. My thesis expands our current understanding of the basic profiles of the three respiratory gases in the GIT lumen, their potential exchange with the vascular system, and the changes associated with feeding. In addition, the potential influence of osmoregulatory functions on these parameters was investigated by conducting a comparative study between freshwater and seawater species; the rainbow trout (Oncorhynchus mykiss) was used as a freshwater model species for in depth investigations and the English sole (Parophrys vetulus) as a comparative seawater species. A combination of in vivo, in situ and in vitro techniques was used to assess these areas at the whole animal, tissue and cellular levels. Based on findings from 5 research chapters, I conclude that both freshwater rainbow trout and seawater English sole have nearly anoxic, hypercapnic and high ammonia environments in the GIT lumen in both fasting and fed conditions. Feeding increases carbon dioxide and ammonia levels, but the GIT epithelia regulates the diffusion of the three respiratory gases into the vascular system regardless of feeding status. The different osmoregulatory requirements in seawater versus freshwater did not greatly affect these conclusions. Furthermore, the intestinal tissues have the capacity to handle and transport two nitrogenous products: urea and ammonia. Throughout the GIT, there were expressions of both a potential NH₄⁺ transporter (NKCC) and NH₃ channels (Rhbg, Rhcg2), but ammonia transport was independent of the PNH3 gradient. The thesis also highlights the importance of the stomach in absorbing ammonia despite a reverse PNH3 gradient at physiologically relevant pH levels.

description: We consider the propagation of wave packets for a one-dimensional nonlinear Schrodinger equation with a matrix-valued potential, in the semi-classical limit. For an initial coherent state polarized along some eigenvector, we prove that the nonlinear evolution preserves the separation of modes, in a scaling such that nonlinear effects are critical (the envelope equation is nonlinear). The proof relies on a fine geometric analysis of the role of spectral projectors, which is compatible with the treatment of nonlinearities. We also prove a nonlinear superposition principle for these adiabatic wave packets.

description: Coherent curvature radiation by charged bunches has been discussed as the radiation mechanism for radio pulsars and fast radio bursts. Important issues for this radiation mechanism include how the bunches form and disperse in the magnetosphere of a pulsar or magnetar. More likely, bunches form and disperse continuously and it remains unclear what the spectral features are for these fluctuating bunches. In this work, we consider that the bunches in a magnetosphere have a formation rate of $λ_B$, a lifetime of $τ_B$, and a typical Lorentz factor of $γ$, and analyze the spectral features of coherent curvature radiation by these fluctuating bunches. We find that the emission spectrum by a single fluctuating bunch is suppressed by a factor of $\sim(λ_Bτ_B)^2$ compared with that of a single persistent bunch, and there is a quasi-white noise in a wider band in the frequency domain. The high-frequency cutoff of the spectrum is at $\sim\max(ω_{\rm peak},2γ^2/τ_B)$, where $ω_{\rm peak}$ is the peak frequency of curvature radiation. If the observed spectrum is not white-noise-like, the condition of $2γ^2λ_B\gtrsim \min(ω_{\rm peak},2γ^2/τ_B)$ would be required. Besides, the radiation by multiple fluctuating bunches along a field line is the incoherent summation of the radiation by single bunches if the bunch separation is longer than the wavelength. Conversely, a coherent summation should be involved. We also discuss the effects of bunch structures and the mechanism of bunch formation and dispersion.

description: Excitons in monolayer transition metal dichalcogenide are endowed with intrinsic valley-orbit coupling between their center-of-mass motion and valley pseudospin. When trapped in a confinement potential, e.g., generated by strain field, we find that intralayer excitons are valley and orbital angular momentum (OAM) entangled. By tuning trap profile and external magnetic field, one can engineer the exciton states at ground state, and realize a series of valley-OAM entangled states. We further show that the OAM of excitons can be transferred to emitted photons, and these novel exciton states can naturally serve as polarization-OAM locked single photon emitters, which under certain circumstance become polarization-OAM entangled, highly tunable by strain trap and magnetic field. Our proposal demonstrates a novel scheme to generate polarization-OAM locked/entangled photons at nanoscale with high degree of integrability and tunability, pointing to exciting opportunities for quantum information applications.

A comprehensive investigation of repetitive head impacts (heading) on brain activity and biomechanics in varsity women's soccer
Creators: name: Kenny, Rebecca A
Publisher: name: University of British Columbia
Year: 2022

description: Soccer players are exposed to a high number of repetitive head impacts (RHIs), which have been hypothesized to lead to cumulative brain trauma. Studies have utilized a variety of methods to estimate exposure to RHIs including self-report, direct observation, modified video analysis and head impact sensors. Such measurements have previously only been done for select events and participants or have relied heavily on memory leading to potential sampling bias and limited understanding of total exposure. Additionally, due to methodological inconsistencies and sex-based differences, previous research has remained inconclusive on potential brain function and health-related changes due to RHIs. This dissertation contains five interconnected studies on female athletes. The first uses encephalography (EEG) and health-related metrics to compare non-contact athletes to soccer players with and without concussions. This chapter establishes that while soccer players without a concussion demonstrate differences to non-contact athletes, they do not demonstrate significant changes compared to soccer players with a concussion. The next chapter demonstrates that soccer players routinely overestimate the number of head impacts experienced in both games and practices. We establish the unreliability of self-report to estimate exposure and suggest video data be used to objectively quantify absolute head exposure. The third chapter is a comprehensive analysis of three years’ worth of video footage to quantify heading frequency. We demonstrate significant inter-player variability withing a single team and demonstrate the necessity of including training sessions, in addition to games, when representing player RHI exposure levels. The fourth chapter quantifies the magnitude of individual head impacts through custom fitted mouthpieces with an accelerometer and gyroscope. We demonstrate which impact scenarios produce the highest kinematics and therefore, which scenarios may pose higher risk. Chapter three and four illustrate the need to study both frequency and magnitude of RHI in research. The final chapter revisits the use of EEG and health-related metrics to evaluate the influence of heading on brain function and behaviour. We demonstrate a potential dose-response between the number of head impacts and resulting changes. Results from these studies contribute to the growing scientific knowledge surrounding RHIs and sets a structure for future quantification of RHIs.

description: Snapshot spectra of a handful of massive young stellar objects (mYSOs) reveal significant variability in line profiles that most likely originate in their circumstellar disk. In two of the mYSOs, the Balmer series, Ca-triplet and Paschen lines show significant change in the disk emission features. In another mYSO the peak-to-peak variation of the double peaked Paschen series changes over time. To our knowledge, this is the first time that spectroscopic variability has been detected in mYSOs. The aim of this project is (i) to measure the amplitude and velocity range of spectral variability of these mYSOs; (ii) to determine the characteristic timescale of this variability; and (iii) to identify the physical origin of this variability. Possible scenarios involve rotating disk structures, a varying accretion flow, and or multiplicity. Characterising the incident rate and extent of variability as well as a timescale associated with this behaviour would be a first step toward systematic spectral variability studies of mYSOs.

Spin vector deviation and the gravitational wave memory effect between two free-falling gyroscopes in the plane wave spacetime

description: In the plane wave spacetime, we find that there will be a precession angle deviation between two free-falling gyroscopes when gravitational waves passed through. This kind of angle deviation is closely related to the well-known standard velocity memory effect. Initial conditions such as the separation velocity or displacement between the two gyroscopes will affect this angle deviation. The evolutions of the angle deviation are calculated for different cases. We find that in some extreme circumstance, the angle deviation's order of magnitude produced by a rotating compact binary source could be $10^{-14}$ rads. Therefore, this memory effect caused by the gravitational wave is likely to be detected in the future.

On Approaching the Ultimate Limits of Photon-Efficient and Bandwidth-Efficient Optical Communication

description: It is well known that ideal free-space optical communication at the quantum limit can have unbounded photon information efficiency (PIE), measured in bits per photon. High PIE comes at a price of low dimensional information efficiency (DIE), measured in bits per spatio-temporal-polarization mode. If only temporal modes are used, then DIE translates directly to bandwidth efficiency. In this paper, the DIE vs. PIE tradeoffs for known modulations and receiver structures are compared to the ultimate quantum limit, and analytic approximations are found in the limit of high PIE. This analysis shows that known structures fall short of the maximum attainable DIE by a factor that increases linearly with PIE for high PIE. The capacity of the Dolinar receiver is derived for binary coherent-state modulations and computed for the case of on-off keying (OOK). The DIE vs. PIE tradeoff for this case is improved only slightly compared to OOK with photon counting. An adaptive rule is derived for an additive local oscillator that maximizes the mutual information between a receiver and a transmitter that selects from a set of coherent states. For binary phase-shift keying (BPSK), this is shown to be equivalent to the operation of the Dolinar receiver. The Dolinar receiver is extended to make adaptive measurements on a coded sequence of coherent state symbols. Information from previous measurements is used to adjust the a priori probabilities of the next symbols. The adaptive Dolinar receiver does not improve the DIE vs. PIE tradeoff compared to independent transmission and Dolinar reception of each symbol.

description: Abstract In this thesis a possibility to outsource the reporting service of radiological institutes on demand was evaluated. The institutes can focus on the examinations, minimize the managerial efforts, eliminate all human resource capacity problems and use our service in cases of medical uncertainty as well. The outsourced radiologist can focus on a subspecialisation. Therefore, faster reading times and a more detailed diagnosis are possible. The patients profit from superior healthcare and the insurance companies from not performed repetitive examinations. To simulate the economical outcome an excel simulation with different adjustable variables was created. The simulation was performed in accordance to the scenario technique, with best, most probable and worst scenario analysis. For this basic case a Market Value Added (MVA) between SFR 4338330.20 and SFR 2380994.18 was shown. The Internal Rate of Return (IRR) was between 694% (best scenario) and 444% (worst scenario). In the second simulation the selling price was reduced to a level of 30% below the competition. In this case the IRR decreased to 350% (best scenario) and 220% (worst scenario). In the last simulation the exchange rate of Euro & Swiss Franc was varied to simulate the project stability on external impact. Thereby, the IRR decreased to 426% (best scenario) and 269% (worst scenario). With this thesis it was shown that from the economical point of view it is profitable to create a company providing outsourcing service to radiological institutes. However, this area is under governmental regulation and legal barriers hinder the creation of the company.

Oscillating behavior of a compartmental model with retarded noisy dynamic infection rate

description: Our study is based on an epidemiological compartmental model, the SIRS model. In the SIRS model, each individual is in one of the states susceptible (S), infected(I) or recovered (R), depending on its state of health. In compartment R, an individual is assumed to stay immune within a finite time interval only and then transfers back to the S compartment. We extend the model and allow for a feedback control of the infection rate by mitigation measures which are related to the number of infections. A finite response time of the feedback mechanism is supposed that changes the low-dimensional SIRS model into an infinite-dimensional set of integro-differential (delay-differential) equations. It turns out that the retarded feedback renders the originally stable endemic equilibrium of SIRS (stable focus) into an unstable focus if the delay exceeds a certain critical value. Nonlinear solutions show persistent regular oscillations of the number of infected and susceptible individuals. In the last part we include noise effects from the environment and allow for a fluctuating infection rate. This results in multiplicative noise terms and our model turns into a set of stochastic nonlinear integro-differential equations. Numerical solutions reveal an irregular behavior of repeated disease outbreaks in the form of infection waves with a variety of frequencies and amplitudes.

description: We present an updated value of the Muonium 1S-2S transition frequency, highlighting contributions from different QED corrections as well as the large uncertainty in the Dirac contribution, stemming from the uncertainty of the electron-to-muon mass ratio. Improving the measurement of this spectral line would allow to extract a more accurate determination of fundamental constants, such as the electron-to-muon mass ratio or, combined with the Muonium hyperfine splitting, an independent value of the Rydberg constant. Furthermore we report on the current status of the Mu-MASS experiment, which aims at measuring the Muonium 1S-2S transition frequency at a 10 kHz uncertainty level.

Gravitational waves from first order phase transitions during inflation

description: We study the production, spectrum and detectability of gravitational waves in models of the early Universe where first order phase transitions occur during inflation. We consider all relevant sources. The self-consistency of the scenario strongly affects the features of the waves. The spectrum appears to be mainly sourced by collisions of bubble of the new phases, while plasma dynamics (turbulence) and the primordial gauge fields connected to the physics of the transitions are generally subdominant. The amplitude and frequency dependence of the spectrum for modes that exit the horizon during inflation are different from those of the waves produced by quantum vacuum oscillations of the metric or by first order phase transitions not occurring during inflation. A moderate number of slow (but still successful) phase transitions can leave detectable marks in the CMBR, but the signal weakens rapidly for faster transitions. When the number of phase transitions is instead large, the primordial gravitational waves can be observed both in the CMBR or with LISA (marginally) and especially DECIGO. We also discuss the nucleosynthesis bound and the constraints it places on the parameters of the models.

description: The dielectric and absorption characteristics of the R-ODFO polyimide film synthesized at the Institute of High Molecular Compounds of the Russian Academy of Sciences were studied. Based on the experimentally measured data of charging currents at temperatures from 25 Â° C to 175 Â° C, an analysis is carried out on the basis of equivalent Voigt and Maxwell schemes. The dielectric Îµ '(Ï), Îµ' '(Ï) characteristics in the low-frequency region are calculated. The temperature dependences of the specific conductivity are obtained. The values of the absorption coefficient and the limiting coefficient are calculated.

description: Features below the first conductance plateau in ballistic quantum point contacts (QPCs) are often ascribed to electron interaction and spin effects within the single mode limit. In QPCs with a highly asymmetric geometry, we observe sharp resonance peaks when the point contacts are gated to the single mode regime, and surprisingly, under certain gating conditions, a complete destruction of the 2e^2/h, first quantum plateau. The temperature evolution of the resonances suggest non-Fermi liquid behavior, while the overall nonlinear characterizations reveal features reminiscent of the 0.7 effect. We attribute these unusual behaviors to the formation of a quasi bound state, which is stabilized by a momentum-mismatch accentuated by asymmetry.
