description: The mobility of p-type nanowires (NWs) of diameters of D=12nm down to D=3nm, in [100], [110], and [111] transport orientations is calculated. An atomistic tight-binding model is used to calculate the NW electronic structure. Linearized Boltzmann transport theory is applied, including phonon and surface roughness scattering (SRS) mechanisms, for the mobility calculation. We find that large mobility enhancements (of the order of 4X) can be achieved as the diameter of the [110] and even more that of the [111] NWs scales down to D=3nm. This enhancement originates from the increase in the dispersion curvatures and consequently the hole velocities as the diameter is scaled. This benefit over compensates the mobility reduction caused by SRS as the diameter reduces. The mobility of the [100] NWs, on the other hand, is the lowest compared the other two NW orientations, and additionally suffers as the diameter scales. The bandstructure engineering techniques we describe are a generic feature of anisotropic bulk bands, and can be also applied to 2D thin-body-layers as well as other channel materials.

description: We report on the optical characterization of site-controlled InP/GaInP quantum dots (QDs). Spatially resolved low temperature cathodoluminescence proves the long-range ordering of the buried emitters, revealing a yield of ∼90% of optically active, positioned QDs and a strong suppression of emitters on interstitial positions. The emission of single QDs shows a pronounced degree of linear polarization along the [0,−1,1] crystal axis with an average degree of polarization of 94%. Photon correlation measurements of the emission from a single QD indicate the single-photon character of the exciton and biexciton emission lines as well as the cascaded nature of the photon pair.

description: Sky coverage is one of the most important pieces of information about astronomical observations. We discuss possible representations, and present algorithms to create and manipulate shapes consisting of generalized spherical polygons with arbitrary complexity and size on the celestial sphere. This shape specification integrates well with our Hierarchical Triangular Mesh indexing toolbox, whose performance and capabilities are enhanced by the advanced features presented here. Our portable implementation of the relevant spherical geometry routines comes with wrapper functions for database queries, which are currently being used within several scientific catalog archives including the Sloan Digital Sky Survey, the Galaxy Evolution Explorer and the Hubble Legacy Archive projects as well as the Footprint Service of the Virtual Observatory.

description: We search for the signature of an isotropic stochastic gravitational-wave background in pulsar timing observations using a frequency-domain correlation technique. These observations, which span roughly 12 yr, were obtained with the 64-m Parkes radio telescope augmented by public domain observations from the Arecibo Observatory. A wide range of signal processing issues unique to pulsar timing and not previously presented in the literature are discussed. These include the effects of quadratic removal, irregular sampling, and variable errors which exacerbate the spectral leakage inherent in estimating the steep red spectrum of the gravitational-wave background. These observations are found to be consistent with the null hypothesis, that no gravitational-wave background is present, with 76 percent confidence. We show that the detection statistic is dominated by the contributions of only a few pulsars because of the inhomogeneity of this data set. The issues of detecting the signature of a gravitational-wave background with future observations are discussed.

We include into consideration high-$K$ isomers that very likely form at the SDO shape. Although half-lives $T_{1/2}\lesssim10^{-5}$ s are calclulated or estimated for even-even spin zero systems, decay hindrances known for high-$K$ isomers suggest that some SDO superheavy nuclei may be detectable by the present experimental technique.

Genomic differentiation of Northern Goshawks in coastal British Columbia
Creators: name: Askelson, Kenneth K.
Publisher: name: University of British Columbia
Year: 2019

description: Understanding the process by which populations become genetically differentiated from one another has been a central goal of population genetics since its inception. With the loss of biodiversity across the globe, we lose information regarding how populations of organisms separate and become genetically distinct. An organism that exemplifies this issue is a subspecies of the Northern Goshawk (Accipiter gentilis laingi; hereafter simple “laingi”) which is classified as Threatened in coastal British Columbia under the Species at Risk Act (Canada) and the Endangered Species Act (USA). Using genotyping-by-sequencing (GBS) data across thousands of SNPs (single nucleotide polymorphisms), we investigate the genetic differentiation of this subspecies and infer the processes governing its distinctiveness. We find that Northern Goshawks on the archipelago of Haida Gwaii are distinct from other populations, clearly separating in principal component analyses, and have a wider distribution of FST and DXY when compared to other populations. In other populations, we recovered weak differentiation ranging from coastal BC to Maine; these populations likely represent the other North American subspecies Accipiter gentilis atricapillus (hereafter, simply “atricapillus”). The second phase of our research was to clarify the range of the laingi subspecies, which previously had been under debate. By selecting laingi-informative single nucleotide polymorphisms (SNPs) from our sequencing data we were able to develop SNP genotyping assays that allowed for the inclusion of hundreds of additional low-quality samples. Using these assays, we find that laingi goshawks are largely restricted to Haida Gwaii. Additionally, we wanted to understand the processes driving differentiation in Haida Gwaii and gene flow between other populations and Haida Gwaii. We found that even though Haida Gwaii is a small population, strong selection is likely shaping the genome. By jointly analyzing our GBS and genotyping data we find that gene flow between Haida Gwaii and other populations is likely low. This thesis contributes to knowledge of a Threatened bird of prey and more generally to how evolutionary distinctness evolves in geographically separated populations of organisms.

description: We consider the problem of stochastic exit from a planar domain, whose boundary is an unstable periodic orbit, and which contains a stable periodic orbit. This problem arises when investigating the distribution of noise-induced phase slips between synchronized oscillators, or when studying stochastic resonance far from the adiabatic limit. We introduce a simple, piecewise linear model equation, for which the distribution of first-passage times can be precisely computed. In particular, we obtain a quantitative description of the phenomenon of cycling: The distribution of first-passage times rotates around the unstable orbit, periodically in the logarithm of the noise intensity, and thus does not converge in the zero-noise limit. We compute explicitly the cycling profile, which is universal in the sense that in depends only on the product of the period of the unstable orbit with its Lyapunov exponent.

These $μ$-constrained representations determine a C*-algebra $A_μ$ for each $μ\in[0,4]$. We prove that these C*-algebras form a continuous bundle of C*-algebras over $[0,4]$ and calculate their K-groups.

description: We present initial results on some of the properties of open clusters NGC 6791 and NGC 6819 derived from asteroseismic data obtained by NASA's Kepler mission. In addition to estimating the mass, radius and log g of stars on the red-giant branch of these clusters, we estimate the distance to the clusters and their ages. Our model-independent estimate of the distance modulus of NGC 6791 is (m-M)_0= 13.11\pm 0.06. We find (m-M)_0= 11.85\pm 0.05 for NGC 6819. The average mass of stars on the red-giant branch of NGC 6791 is 1.20 \pm 0.01 M_sun, while that of NGC 6819 is 1.68\pm 0.03M_sun. It should be noted that we do not have data that cover the entire red-giant branch and the actual mass will be somewhat lower. We have determined model-dependent estimates of ages of these clusters. We find ages between 6.8 and 8.6 Gyr for NGC 6791, however, most sets of models give ages around 7Gyr. We obtain ages between 2 and 2.4 Gyr for NGC 6819.

Linear magnetoresistance in commercial n-type silicon due to inhomogeneous doping

description: Free electron theory tells us that resistivity is independent of magnetic field. In fact, most observations match the semiclassical prediction of a magnetoresistance that is quadratic at low fields before saturating. However, a non-saturating linear magnetoresistance has been observed in exotic semiconductors such as silver chalcogenides, lightly-doped InSb, N-doped InAs, MnAs-GaAs composites, PrFeAsO, and epitaxial graphene. Here we report the observation of a large linear magnetoresistance in the ohmic regime in commonplace commercial n-type silicon wafer. It is well-described by a classical model of spatially fluctuating donor densities, and may be amplified by altering the aspect ratio of the sample to enhance current-jetting: increasing the width tenfold increased the magnetoresistance at 8 T from 445 % to 4707 % at 35 K. This physical picture may well offer insights into the large magnetoresistances recently observed in n-type and p-type Si in the non-ohmic regime.

A Game Theoretical Approach to Modeling Full-Duplex Information Dissemination

Subjects: subject: Computer Science and Game Theory (cs.GT)

description: One major function of social networks (e.g., massive online social networks) is the dissemination of information such as scientific knowledge, news, and rumors. Information can be propagated by the users of the network via natural connections in written, oral or electronic form. The information passing from a sender to a receiver intrinsically involves both of them considering their self-perceived knowledge, reputation, and popularity, which further determine their decisions of whether or not to forward the information and whether or not to provide feedback. To understand such human aspects of the information dissemination, we propose a game theoretical model of the two-way full duplex information forwarding and feedback mechanisms in a social network that take into account the personalities of the communicating actors (including their perceived knowledgeability, reputation, and desire for popularity) and the global characteristics of the network. The model demonstrates how the emergence of social networks can be explained in terms of maximizing game theoretical utility.

description: We compute new chemical profiles for the core and envelope of white dwarfs appropriate for pulsational studies of ZZ Ceti stars. These profiles are extracted from the complete evolution of progenitor stars, evolved through the main sequence and the thermally-pulsing asymptotic giant branch (AGB) stages, and from time-dependent element diffusion during white dwarf evolution. We discuss the importance of the initial-final mass relationship for the white dwarf carbon-oxygen composition. In particular, we find that the central oxygen abundance may be underestimated by about 15% if the white dwarf mass is assumed to be the hydrogen-free core mass before the first thermal pulse. We also discuss the importance for the chemical profiles expected in the outermost layers of ZZ Ceti stars of the computation of the thermally-pulsing AGB phase and of the phase in which element diffusion is relevant. We find a strong dependence of the outer layer chemical stratification on the stellar mass. In particular, in the less massive models, the double-layered structure in the helium layer built up during the thermally-pulsing AGB phase is not removed by diffusion by the time the ZZ Ceti stage is reached. Finally, we perform adiabatic pulsation calculations and discuss the implications of our new chemical profiles for the pulsational properties of ZZ Ceti stars. We find that the whole $g-$mode period spectrum and the mode-trapping properties of these pulsating white dwarfs as derived from our new chemical profiles are substantially different from those based on chemical profiles widely used in existing asteroseismological studies. Thus, we expect the asteroseismological models derived from our chemical profiles to be significantly different from those found thus far.

description: The condensations composing coronal rain, falling down along loop-like structures observed in cool chromospheric lines such as H$α$ and \ion{Ca}{2} H, have long been a spectacular phenomenon of the solar corona. However, considered a peculiar sporadic phenomenon, it has not received much attention. This picture is rapidly changing due to recent high resolution observations with instruments such as \textit{Hinode}/SOT, CRISP of \textit{SST} and \textit{SDO}. Furthermore, numerical simulations have shown that coronal rain is a loss of thermal equilibrium of loops linked to footpoint heating. This result has highlighted the importance that coronal rain can play in the field of coronal heating. In this work, we further stress the importance of coronal rain by showing the role it can play in the understanding of the coronal magnetic field topology. We analyze \textit{Hinode}/SOT observations in the \ion{Ca}{2} H line of a loop in which coronal rain puts in evidence in-phase transverse oscillations of multiple strand-like structures. The periods, amplitudes, transverse velocities and phase velocities are calculated, allowing an estimation of the energy flux of the wave and the coronal magnetic field inside the loop through means of coronal seismology. We discuss the possible interpretations of the wave as either standing or propagating torsional Alfvén or fast kink waves. An estimate of the plasma beta parameter of the condensations indicates a condition that may allow the often observed separation and elongation processes of the condensations. We also show that the wave pressure from the transverse wave can be responsible for the observed low downward acceleration of coronal rain.

description: In this paper, we present a study into the learning experience as users learn to use interactive artifacts. This learning experience both evolves over the entire time that a user uses an artifact and is personally meaningful for its users. It is defined by the intentional relations that users have with artifacts as well as how users negotiate their use. In this paper, we summarize this study and early findings into these factors to understand the “learning-in-use” of an interactive artifact. This paper contributes to our understanding of how we learn to use interactive artifacts and how users’ relationships with artifacts evolve over time.

description: The combined effect of frustration and correlation in electrons is a matter of considerable interest of late. In this context a Falicov-Kimball model on a triangular lattice with two localized states, relevant for certain correlated systems, is considered. Making use of the local symmetries of the model, our numerical study reveals a number of orbital ordered ground states, tuned by the small changes in parameters while quantum fluctuations between the localized and extended states produce homogeneous mixed valence. The inversion symmetry of the Hamiltonian is broken by most of these ordered states leading to orbitally driven ferroelectricity. We demonstrate that there is no spontaneous symmetry breaking when the ground state is inhomogeneous. The study could be relevant for frustrated systems like $GdI_2$, $NaTiO_2$ (in its low temperature C2/m phase) where two Mott localized states couple to a conduction band.

description: The first decades of the XXI century were marked by the active development of information and communication technologies, including in electoral and political spheres. The COVID-19 pandemic has given a powerful additional impetus to these processes. The practice has become ahead of regulation, both nationally and internationally. The lack of unifi ed legal enactments regulating the digitalization of socially significant procedures (primarily in the electoral sphere) is a constraining factor in the development of political processes of a new reality. The author is sure that it is necessary to unite the efforts of legislators, relevant public and international organizations to develop improved rules for political life of society in the digital environment, where the balance of guaranteed rights and freedoms of citizens will be maintained, on the one hand, and a high level of security, reliability and effi ciency of new technologies, on the other hand.

description: We present a new adaptive kernel density estimator based on linear diffusion processes. The proposed estimator builds on existing ideas for adaptive smoothing by incorporating information from a pilot density estimate. In addition, we propose a new plug-in bandwidth selection method that is free from the arbitrary normal reference rules used by existing methods. We present simulation examples in which the proposed approach outperforms existing methods in terms of accuracy and reliability.

Cholesterol metabolism as a target in castration-resistant prostate cancer
Creators: name: Gordon, Jacob
Publisher: name: University of British Columbia

description: Despite clinical benefits of existing prostate cancer treatments, patients continue to develop therapeutic resistance. Persistence of androgen receptor pathway activity is attributed to several mechanisms associated with resistance, including intratumoral androgen receptor agonist synthesis from the precursor cholesterol. Cholesterol has been correlated to poor outcomes in patients and clinically the use of cholesterol synthesis inhibitors, statins, improves prostate cancer survival. The expression of the high-density lipoprotein-cholesterol receptor, scavenger receptor B1 (SR-B1), is elevated in castration-resistant prostate cancer models and has been linked to poor survival of patients. The overarching hypothesis of this thesis is that cholesterol modulation, through either synthesis or uptake inhibition, will impact essential signaling processes impeding the proliferation of prostate cancer. Clinically statin use was found to improve the overall survival of metastatic castration-resistant prostate cancer patients receiving the androgen synthesis inhibitor abiraterone. In vivo experiments demonstrated the ability of statins to impede post-castration biochemical recurrence and reduce tumor growth and androgen receptor agonist synthesis in LNCaP-derived xenograft tumors. SR-B1 was found to be overexpressed in clinical samples from both local and metastatic prostate cancer. Antagonism of SR-B1 in steroid responsive C4-2 cells decreased cholesterol uptake and growth and induced cell cycle arrest. Initially attributed to an observed decrease in de novo steroid synthesis and androgen receptor activity, the inability of exogenous steroid to restore cellular proliferation or androgen receptor activity indicated steroid independent cellular arrest. As such, cellular stress and nutrient deprivation responses were assessed and SR-B1 antagonism was found to induce both autophagy and endoplasmic reticulum stress markers. Given the steroid-independent manner of SR-B1 antagonism mediated cellular arrest, the effects of SR-B1 antagonism on androgen independent PC-3 cells was assessed and found to result in robust cellular death in vitro and decreased growth of xenograft tumors. These findings demonstrate that the reduction of cellular cholesterol availability can impede prostate cancer proliferation through both decreased steroid-synthesis and steroid-independent mechanisms providing a potential therapeutic target for the treatment of prostate cancer.

description: Со второй половины XX в. политические партии как социально-политический институт оказались в состоянии глобального кризиса, проявлениями которого стали снижение численности их членов и падение уровня доверия им. Целью исследования является анализ факторов, влияющих на уровень доверия политическим партиям в странах Европейского Союза, задачами – выявление данных факторов и определение наличия корреляции между ними и уровнем доверия политическим партиям. В рамках настоящего исследования в качестве показателей, коррелирующих с уровнем доверия партиям в общеевропейском масштабе, рассматриваются уровень доверия национальному правительству, национальному парламенту, а также уровень экономического развития. Исследование опирается на сравнительный и статистический методы. Источником анализа являются данные социологических опросов о доверии политическим партиям, публикуемые на официальном сайте Европейской комиссии по итогам опросов населения в рамках исследования «Евробарометр» за период с 2000 г. по настоящее время. В качестве зависимой переменной выступает уровень доверия политическим партиям, определяемый в процентах от числа респондентов, доверяющих данному социальному институту. Проведенный анализ позволяет утверждать, что наиболее низкий уровень доверия политическим партиям характерен для стран, которые имеют низкий уровень доверия национальным правительству и парламенту, а также для государств, где длительное время существовали недемократические режимы. Также уровень доверия политическим партиям коррелирует с уровнем экономического развития, но степень его корреляции ниже по сравнению с другими рассмотренными показателями. Уровень доверия политическим партиям ниже среднеевропейского характерен главным образом для стран, сравнительно недавно ставших на путь демократии – Прибалтики, Восточной и Южной Европы.

description: It has been known since many decades that galaxy interactions can induce star formation (hereafter SF) enhancements and that one of the driving mechanisms of this enhancement is related to gas inflows into the central galaxy regions, induced by asymmetries in the stellar component, like bars. In the last years many evidences have been accumulating, showing that interacting pairs have central gas-phase metallicities lower than those of field galaxies, by {\sim} 0.2-0.3 dex on average. These diluted ISM metallicities have been explained as the result of inflows of metal-poor gas from the outer disk to the galaxy central regions. A number of questions arises: What's the timing and the duration of this dilution? How and when does the SF induced by the gas inflow enrich the circumnuclear gas with re-processed material? Is there any correlation between the timing and strength of the dilution and the timing and intensity of the SF? By means of Tree-SPH simulations of galaxy major interactions, we have studied the effect that gas inflows have on the ISM dilution, and the effect that the induced SF has, subsequently, in re-enriching the nuclear gas. In this contribution, we present the main results of this study.

description: The mechanical vapor recompression is an efficient process to decrease energy consumption of drying processes. In order to use the mechanical vapor recompression (MVR) in residential clothe dryers, the volumetric Turbivo technology is used to design a dry water vapor compressor. The Turbivo volumetric machine is composed mainly of a rotor with one blade, a stator, and a mobile oscillating thrust. The advantages of Turbivo(R) technology are the absence of contact between rotor and stator as well as the oil-free operation. A model of the Turbivo compressor, including kinematic, dynamic, and thermodynamic analysis is presented. The compressor internal tightness is ensured by a surface treatment of the compressor components. Using the model, a water vapor Turbivo compressor of 12m3/h and compression ratio of 5 has been sized and realized. The compressor prototype will be tested on a dedicated test bench to characterize its volumetric and isentropic efficiencies.

description: One of the most striking manifestations of orderly behavior emerging out of complex interactions in any astrophysical system is the 11-year cycle of sunspots. However, direct sunspot observations and reconstructions of long-term solar activity clearly exhibit amplitude fluctuations beyond the decadal timescale -- which may be termed as supradecadal modulation. Whether this long-term modulation in the Sun's magnetic activity results from nonlinear mechanisms or stochastic perturbations remains controversial and a matter of active debate. Utilizing multi-millennial scale kinematic dynamo simulations based on the Babcock-Leighton paradigm -- in the likely (near-critical) regime of operation of the solar dynamo -- we demonstrate that this supradecadal modulation in solar activity cannot be explained by nonlinear mechanisms alone; stochastic forcing is essential for the manifestation of observed long-term fluctuations in the near-critical dynamo regime. Our findings substantiate some independent observational and theoretical investigations, and provide additional insights into temporal dynamics associated with a plethora of natural phenomena in astronomy and planetary systems arising from weakly nonlinear, non-deterministic processes.

description: Using some modification of the standard fermion technique we derive factorized formula for spin operator matrix elements (form-factors) between general eigenstates of the Hamiltonian of quantum Ising chain in a transverse field of finite length. The derivation is based on the approach recently used to derive factorized formula for Z_N-spin operator matrix elements between ground eigenstates of the Hamiltonian of the Z_N-symmetric superintegrable chiral Potts quantum chain. The obtained factorized formulas for the matrix elements of Ising chain coincide with the corresponding expressions obtained by the Separation of Variables Method.

description: A so far not considered energy loss mechanism in suspended micro- and nanoresonators due to noncontact acoustical energy loss is investigated theoretically. The mechanism consists on the conversion of the mechanical energy from the vibratory motion of the resonator into acoustic waves on large nearby structures, such as the substrate, due to the coupling between the resonator and those structures resulting from the Casimir force acting over the separation gaps. Analytical expressions for the resulting quality factor Q for cantilever and bridge micro- and nanoresonators in close proximity to an underlying substrate are derived and the relevance of the mechanism is investigated, demonstrating its importance when nanometric gaps are involved.
Real-time computer vision in software using custom vector overlays

Publisher: name: University of British Columbia

description: Real-time computer vision places stringent performance requirements on embedded systems. Often, dedicated hardware is required. This is undesirable as hardware development is time-consuming, requires extensive skill, and can be difficult to debug. This thesis presents three case studies of accelerating computer vision algorithms using a software-driven approach, where only the innermost computation is performed with dedicated hardware. As a baseline, the algorithms are initially run on a scalar host processor. Next, the software is sped up using an existing vector overlay implemented in the FPGA fabric, manually rewriting the code to use vectors. Finally, the overlay is customized to accelerate the critical inner loops by adding hardware-assisted custom vector instructions. Collectively, the custom instructions require very few lines of RTL code compared to what would be needed to implement the entire algorithm in dedicated hardware. This keeps design complexity low and yields a significant performance boost. For example, in one system, we measured a performance advantage of 2.4× to 3.5× over previous state-of-the-art dedicated hardware systems while using far less custom hardware
