description: With the classical three-dimensional ensemble model, we have investigated the microscopic recollision dynamics in nonsequential double ionization of helium by 800 nm laser pulses at 2.0 PW/cm^2. We demonstrate that the asymmetric energy sharing between the two electrons at recollision plays a decisive role in forming the experimentally observed V-shaped structure in the correlated longitudinal electron momentum spectrum at the high laser intensity [Phys. Rev. Lett. 99, 263003 (2007)]. This asymmetric energy sharing recollision leaves footprints on the transverse electron momentum spectra, which provide a new insight into the attosecond three-body interactions.

description: In this Paper we report the discovery of CXO J122518.6+144545; a peculiar X-ray source with a position 3.6+-0.2",off-nuclear from an SDSS DR7 z=0.0447 galaxy. The 3.6" offset corresponds to 3.2 kpc at the distance of the galaxy. The 0.3-8 keV X-ray flux of this source is 5x10^-14 erg cm^-2 s^-1 and its 0.3-8 keV luminosity is 2.2x10^41 erg/s (2.7x10^41 erg/s; 0.5-10 keV) assuming the source belongs to the associated galaxy. We find a candidate optical counterpart in archival HST/ACS g'-band observations of the field containing the galaxy obtained on June 16, 2003. The observed magnitude of g'=26.4+-0.1 corresponds to an absolute magnitude of -10.1. We discuss the possible nature of the X-ray source and its associated candidate optical counterpart and conclude that the source is either a very blue type IIn supernova, a ULX with a very bright optical counterpart or a recoiling super-massive black hole.

description: We provide an introduction to logarithmic potential theory in the complex plane that particularly emphasizes its usefulness in the theory of polynomial and rational approximation. The reader is invited to explore the notions of Fekete points, logarithmic capacity, and Chebyshev constant through a variety of examples and exercises. Many of the fundamental theorems of potential theory, such as Frostman's theorem, the Riesz Decomposition Theorem, the Principle of Domination, etc., are given along with essential ideas for their proofs. Equilibrium measures and potentials and their connections with Green functions and conformal mappings are presented. Moreover, we discuss extensions of the classical potential theoretic results to the case when an external field is present.
Fixation, transient landscape and diffusion's dilemma in stochastic evolutionary game dynamics

Subjects: subject: Populations and Evolution (q-bio.PE)

description: Agent-based stochastic models for finite populations have recently received much attention in the game theory of evolutionary dynamics. Both the ultimate fixation and the pre-fixation transient behavior are important to a full understanding of the dynamics. In this paper, we study the transient dynamics of the well-mixed Moran process through constructing a landscape function. It is shown that the landscape playing a central theoretical "device" that integrates several lines of inquiries: the stable behavior of the replicator dynamics, the long-time fixation, and continuous diffusion approximation associated with asymptotically large population. Several issues relating to the transient dynamics are discussed: (i) multiple time scales phenomenon associated with intra- and inter-attractoral dynamics; (ii) discontinuous transition in stochastically stationary process akin to Maxwell construction in equilibrium statistical physics; and (iii) the dilemma diffusion approximation facing as a continuous approximation of the discrete evolutionary dynamics. It is found that rare events with exponentially small probabilities, corresponding to the uphill movements and barrier crossing in the landscape with multiple wells that are made possible by strong nonlinear dynamics, plays an important role in understanding the origin of the complexity in evolutionary, nonlinear biological systems.

description: A Hidden Markov Model (HMM) is a common statistical model which is widely used for analysis of biological sequence data and other sequential phenomena. In the present paper we show how HMMs can be extended with side-constraints and present constraint solving techniques for efficient inference. Defining HMMs with side-constraints in Constraint Logic Programming have advantages in terms of more compact expression and pruning opportunities during inference. We present a PRISM-based framework for extending HMMs with side-constraints and show how well-known constraints such as cardinality and all different are integrated. We experimentally validate our approach on the biologically motivated problem of global pairwise alignment.

description: The predictive power of mean-field theory is emphasized by comparing theory with simulations under controlled conditions. The recently developed test-field method is used to extract turbulent transport coefficients both in kinematic as well as nonlinear and quasi-kinematic cases. A striking example of the quasi-kinematic method is provided by magnetic buoyancy-driven flows that produce an alpha effect and turbulent diffusion.

description: We study a spin-gas model, where N_S system qubits are interacting with N_B bath qubits via many-body interactions. We consider multipartite Ising interactions and show how the effect of decoherence depends on the specific coupling between the system and its environment. For instance, we analyze the influence of decohenerce induced by k-body interactions for different values of k. Moreover, we study how the effect of decoherence depends on the correlation between baths that are coupled to different individual system qubit and compare Markovian with non-Markovian interactions. As examples we consider specific quantum many-body states and investigate their evolution under several different decoherence models. As a complementary investigation we study how the coupling to the environment can be employed to generate a desired multipartite state.

description: We have produced a fluid dynamics video with data from Direct Numerical Simulation (DNS) of a jet in crossflow at several low values of the velocity inflow ratio R. We show that, as the velocity ratio R increases, the flow evolves from simple periodic vortex shedding (a limit cycle) to more complicated quasi-periodic behavior, before finally exhibiting asymmetric chaotic motion. We also perform a stability analysis just above the first bifurcation, where R is the bifurcation parameter. Using the overlap of the direct and the adjoint eigenmodes, we confirm that the first instability arises in the shear layer downstream of the jet orifice on the boundary of the backflow region just behind the jet.

Enhancement of dark matter relic density from the late time dark matter conversions

description: We demonstrate that if the dark matter (DM) in the Universe contains multiple components,the interactions between the DM components may induce DM conversions. It is then possible that the lightest DM component with an annihilation cross section much larger than that of the typical weakly interacting massive particle (WIMP) can obtain a relic density in consistent with the cosmological observations, due to an enhancement from the DM conversion process at late time after the thermal decoupling. This provides an alternative source of large boost factor required to explain the excesses reported by the recent DM indirect search experiments.

Investigating the genomic contributions to familial intracranial aneurysms in a First Nation from Northern British Columbia
Creators: name: Newman-Simmons, Avery
Publisher: name: University of British Columbia
Year: 2021

description: INTRODUCTION: Familial intracranial aneurysms (FIA) may present with Mendelian inheritance and an increased risk for first-degree relatives to develop intracranial aneurysms, at a younger age, and with a higher risk of them rupturing in comparison to their sporadic counterparts. However, since genetic research on this non-syndromic condition began in the early 2000’s only a few disease-gene associations have been discovered and much of the aetiology is still missing. Most of these genetic studies have focused primarily on European and East Asian populations although IA has been well documented in Canadian and Greenlandic Inuit. To our knowledge, we are presenting the first extensive whole genome sequencing study on FIA in several First Nation families from a community in Northwestern British Columbia, Canada. METHODS: Whole genome sequencing was completed for 6 affected individuals, selected for having as distant a relationship as possible. To identify single nucleotide variations, small indels, mitochondrial variations, and structural variations that could cause FIA, various filtration strategies which included read depth and genotype quality controls, gnomAD minor allele frequencies, sequence ontology, and allele sharing between five or more participants were used. Filtered variants were subsequently prioritized based on extensive annotation information and biological significance thorough a literature search. RESULTS: We found 25 single nucleotide variations that passed the initial filtration strategy. After prioritization, seven top variant candidates in the HEMK1, CPT1A, LOC105371356, TUSC3, PLCB3, DKK3, and KRT8 genes remained. Extensive annotation and literature search results demonstrated that the PLCB3 p.R874Q missense variant was the strongest among the seven top variant candidates. However, without a population specific variant iv database to permit identification and removal of common population-specific variants no further prioritization could be completed. CONCLUSION: From available data, rare variants were found in this family, but without adequate Indigenous representation in variant databases, interpretation accuracy is limited. Future studies of this family should utilize linkage to localize a single region if possible and also long-read sequencing potentially in order to ensure all variants in a linked region have been identified. The present study has largely ruled out currently known Mendelian disorders associated with intracranial aneurysms.

description: We report a direct lattice calculation of the $K$ to $ππ$ decay matrix elements for both $ΔI=1/2$ and $3/2$ channels on 2+1 flavor, domain wall fermion, $16^3\times32$ lattices with zero $ππ$ relative momentum and $m_π=420$ MeV. All $K^0$ to $ππ$ contractions are carefully listed and calculated. The decay into the isospin zero $ππ$ final state, which receives contributions from the disconnected graphs, is very difficult to calculate, but a clear signal in the similar disconnected $ππ$ correlator can be seen. Preliminary results, some with large errors, will be presented for the various contributions to the renormalized weak matrix elements $A_0$ and $A_2$. We obtain Re$(A_0)$ with $25%$ error in the case of zero momentum on shell decay, and find a factor of 6 enhancement for the $ΔI=1/2$ rule in the $420$ MeV pion system.

description: We report Westerbork Synthesis Radio Telescope and Arecibo Telescope observations of the redshifted satellite OH-18cm lines at $z \sim 0.247$ towards PKS1413+135. The "conjugate" nature of these lines, with one line in emission and the other in absorption, but with the same shape, implies that the lines arise in the same gas. The satellite OH-18cm line frequencies also have different dependences on the fine structure constant $α$, the proton-electron mass ratio $μ= m_p/m_e$, and the proton gyromagnetic ratio $g_p$. Comparisons between the satellite line redshifts in conjugate systems can hence be used to probe changes in $α$, $μ$, and $g_p$, with few systematic effects. The technique yields the expected null result when applied to Cen.A, a nearby conjugate satellite system. For the $z \sim 0.247$ system towards PKS1413+135, we find, on combining results from the two telescopes, that $[ΔG/G] = (-1.18 \pm 0.46) \times 10^{-5}$ (weighted mean), where $G = g_p [μα^2]^{1.85}$; this is tentative evidence (with $2.6 σ$ significance, or at 99.1% confidence) for a smaller value of $α$, $μ$, and/or $g_p$ at z~0.247, i.e. at a lookback time of ~2.9 Gyrs. If we assume that the dominant change is in $α$, this implies $[Δα/α] = (-3.1 \pm 1.2) \times 10^{-6}$. We find no evidence that the observed offset might be produced by systematic effects, either due to observational or analysis procedures, or local conditions in the molecular cloud.

description: Сформулировано направление интенсификации процессов деформирования и повышения эксплуатационных характеристик изделий. Его суть заключается в том, что с помощью оптимизации кристаллографической ориентации структуры конструкционных материалов можно изменять преимущественное развитие деформаций при обработке давлением в пользу тех направлений, которые приведут к повышению предельного формоизменения заготовок, точности геометрических параметров и усталостных характеристик изделий. Приведены теоретические основы проектирования материалов с заданной кристаллографией структуры. Полученные функциональные взаимосвязи позволяют учесть параметры строения металлов и сплавов в технологических расчетах процессов обработки давлением, а главное априорно определить кристаллографию структуры, отвечающую требованиям повышения деформационных возможностей материалов. Рассмотрен пример реализации расчетной кристаллографической ориентации структуры при прокатке высокопрочной ленты из алюминиевого сплава 3104.

description: In chameleon dark energy models, local gravity constraints tend to rule out parameters in which observable cosmological signatures can be found. We study viable chameleon potentials consistent with a number of recent observational and experimental bounds. A novel chameleon field potential, motivated by f(R) gravity, is constructed where observable cosmological signatures are present both at the background evolution and in the growth-rate of the perturbations. We study the evolution of matter density perturbations on low redshifts for this potential and show that the growth index today gamma_0 can have significant dispersion on scales relevant for large scale structures. The values of gamma_0 can be even smaller than 0.2 with large variations of gamma on very low redshifts for the model parameters constrained by local gravity tests. This gives a possibility to clearly distinguish these chameleon models from the Lambda-Cold-Dark-Matter model in future high-precision observations.

description: As the thinnest atomic membrane, graphene presents an opportunity to combine geometry, elasticity and electronics at the limits of their validity. The availability of reliable atomistic potentials for graphene allows unprecedented precise simulations of the mechanical response of atomic membranes. Here we describe the transport and electronic structure in the neighbourhood of conical singularities, the elementary excitations of the ubiquitous wrinkled and crumpled graphene that occur in non-epitaxial suspended samples where shear stresses are unavoidable. We use a combination of atomistic mechanical simulations, analytical geometry and transport calculations in curved graphene, and exact diagonalization of the electronic spectrum to calculate the effects of geometry on electronic structure, transport and mobility in suspended samples. We also point out how the geometry-generated pseudo-magnetic/electric fields might disrupt Landau quantization under a magnetic field.

We use the "strong" nonlinearity to obtain results on existence, shape, stability and dynamics of the soliton. The main result of this paper (Theorem 1) shows that for ε\to0 the orbit of our soliton approaches the orbit of a classical particle in a potential V(x).

description: We explore the possibility of passive error correction in the toric code model. We first show that even coherent dynamics, stemming from spin interactions or the coupling to an external magnetic field, lead to logical errors. We then argue that Anderson localization of the defects, arising from unavoidable fluctuations of the coupling constants, provides a remedy. This protection is demonstrated using general analytical arguments that are complemented with numerical results which demonstrate that self-correcting memory can in principle be achieved in the limit of a nonzero density of identical defects.

The longest timescale X-ray variability reveals an evidence for active galactic nuclei in the high accretion state

description: The All Sky Monitor (ASM) onboard the Rossi X-ray Timing Explorer (RXTE) has continuously monitored a number of Active galactic nuclei (AGNs) with similar sampling rates for 14 years from 1996 January to 2009 December. Utilizing the archival ASM data of 27 AGNs, we calculate the normalized excess variances of the 300-day binned X-ray light curves on the longest timescale (between 300 days and 14 years) explored so far. The observed variance appears to be independent of AGN black hole mass and bolometric luminosity, respectively. According to the scaling relation with black hole mass (and bolometric luminosity) from Galactic black hole X-ray binaries (GBHs) to AGNs, the break timescales which correspond to the break frequencies detected in the power spectral density (PSD) of our AGNs are larger than binsize (300 days) of the ASM light curves. As a result, the singly broken power-law (soft-state) PSD predicts the variance to be independent of mass and luminosity, respectively. Nevertheless, the doubly-broken power-law (hard-state) PSD predicts, with the widely accepted ratio of the two break frequencies, that the variance increases with increasing mass and decreases with increasing luminosity, respectively. Therefore, the independence of the observed variance on mass and luminosity suggests that AGNs should have the soft-state PSDs. If taking into account the scaling of breaking timescale with mass and luminosity synchronously, the observed variances are also more consistent with the soft-state than the hard-state PSD predictions. With the averaged variance of AGNs and the soft-state PSD assumption, we obtain a universal PSD amplitude of $0.030\pm0.022$. By analogy with the GBH PSDs in the high/soft state, the longest timescale variability supports the standpoint that AGNs are scaled-up GBHs in the high accretion state, as already implied by the direct PSD analysis.

description: Objectives: An ethanol extract of the whole plants of Saussurea medusa had been investigated to find novel anti-inflammatory sesquiterpenoids. Methods: Extensive spectroscopic data and chemical methods were applied to elucidate the structures of the compounds. Results: One new megastigmane sesquiterpenoid (1), along with 11 known analogues (2–12), were obtained from S. medusa. All isolates, except compounds 3 and 6, were mentioned from the studied plant for the first time. Compounds 1, 2, 4, 5, 7, 8 and 12 were firstly isolated from the genus Saussurea. Compounds 2, 9 and 10 were found to inhibit the lipopolysaccharide (LPS)-induced release of NO by RAW264.7 cells with IC50 values ranging from 21.1 ± 1.7 to 46.7 ± 1.9 μM. Furthermore, iNOS expression experiment was performed to examine the interactions between the active compounds and the iNOS enzyme.

description: We present a new mechanism for slow-roll inflation based on higher dimensional supersymmetric gauge theory compactified to four dimensions with twisted (supersymmetry breaking) boundary conditions. These boundary conditions lead to a potential for directions in field space that would have been flat were supersymmetry preserved. For field values in these directions much larger than the supersymmetry-breaking scale, the flatness of the potential is nearly restored. Starting in this nearly flat region, inflation can occur as the theory relaxes towards the origin of field space. Near the origin, the potential becomes steep and the theory quickly descends to a confining gauge theory in which the inflaton does not exist as a particle. This confining gauge theory could be part of the Standard Model (QCD) or a natural dark matter sector; we comment on various scenarios for reheating. As a specific illustration of this mechanism, we discuss 4+1 dimensional maximally supersymmetric gauge theory on a circle with antiperiodic boundary conditions for fermions. When the theory is weakly coupled at the compactification scale, we calculate the inflaton potential directly in field theory by integrating out the heavy W-bosons and their superpartners. At strong coupling the model can be studied using a gravity dual, which realizes a new model of brane inflation on a non-supersymmetric throat geometry. Assuming there exists a UV completion that avoids the eta-problem, predictions from our model are consistent with present observations, and imply a small tensor-to-scalar ratio.

The conditional nature of the mammalian hypercapnic ventilatory response : effect of age, state, and temperature
Creators: name: Sprenger, Ryan Joseph
Publisher: name: University of British Columbia
Year: 2021

description: CO₂ is the primary respiratory stimulant under resting conditions in mammals and an elevation in internal or environmental CO₂ causes an increase in ventilation. My thesis focuses on two conditions in which the magnitude of the ventilatory response to excess CO₂ is altered within an animal: postnatal development and hibernation. I first examine the development of the hypercapnic ventilatory response (HCVR) in two fossorial species (golden-Syrian hamsters and 13-lined ground squirrels) to determine if the blunted adult fossorial HCVR is developed or inherited, then raised those species in burrow conditions to determine how peri- and postnatal exposure to burrow conditions affects the adult response. Both species developed their blunted adult HCVR over the first 15 days after birth, and peri- and postnatal exposure to the burrow environment sped up the development of the HCVR (5-10 days) without affecting the adult response. My data suggest that the HCVR is likely genetically determined and strongly influenced by neurochemical development which produces but not regulates the observed patterns in the development of the HCVR. I next examined the relatively elevated HCVR seen in adult hibernating mammals. I found that the HCVR diminishes during a period of CO₂ retention early in entrance into hibernation (where 7% CO₂ does not elicit a ventilatory response) that appears to contribute to metabolic suppression. After, it rises to the elevated HCVR in hibernation (~650% increase to 7% CO₂) tracking the reduction in metabolic rate. In steady state hibernation, the HCVR was elevated and plastic based on changes in metabolic rate, state, and body temperature. On arousal the HCVR is elevated further (~750% increase to 7% CO₂) when the animals are expelling excess CO₂ before falling as metabolic rate rises on arousal. These data suggest that chemoreceptor input, or changes to the integration of that input were altered but I confirm that the locus coeruleus is not involved in the changes in the HCVR during hibernation. Unlike development, CO₂ sensitivity appears to be tightly regulated to facilitate retention or expulsion of CO₂ in hibernation, thus the nature of the changes in CO₂ sensitivity are different between development and hibernation.

description: Content generation in virtual environments is becoming increasingly important with the rise of virtual and augmented reality technologies and growing demand for immersive experiences. This raises a problem of efficient content generation to meet with higher requirements for both the quantity and quality of the contents that could be used inside virtual environments. This dissertation explored the possibilities of formulating design problems as computational problems based on optimization theory in different scenarios, and explored what can be viable application cases, as well as what can be viable cost terms for each application case based on the theory. In total four application scenarios are included. The optimization theory used in this dissertation is the Markov chain Monte Carlo optimization method called “simulated annealing”. By doing this we can transform a design problem to a computation problem and use computational methods to quickly solve the problem and generate content. This dissertation contains the papers published by the author during her Ph.D. Each published article included in this dissertation deals with a specific application case based on optimization theory. The author investigated four distinct application cases. The first case centered on the synthesis of drills for virtual reality racket sports. The second case focused on designing virtual reality game level layouts, based on the layout of a real-world environment. The third case explored collaborative gameplay design, with the aim of synthesizing game levels that require a predetermined degree of collaboration between two players to complete. The aim of the fourth application case was to create virtual reality fire evacuation training drills that could be used for training purposes in simulated environments. Different cost terms are proposed based on different application cases to synthesize contents that align with the design intent.

description: We revisit the phase diagram of the frustrated s=1/2 spin ladder with antiferromagnetic rung and diagonal couplings. In particular, we reexamine the evidence for the columnar dimer phase, which has been predicted from analytic treatment of the model and has been claimed to be found in numerical calculations. By considering longer chains and by keeping more states than in previous work using the density-matrix renormalization group, we show that the numerical evidence presented previously for the existence of the dimerized phase is not unambiguous in view of the present more careful analysis. While we cannot completely rule out the possibility of a dimerized phase in the cross-coupled ladder, we do set limits on the maximum possible value of the dimer order parameter that are much smaller than those found previously.

description: An efficient scheme is proposed to carry out gate operations on an array of trapped Yb$^+$ ions, based on a previous proposal using both electronic and nuclear degrees of freedom in a magnetic field gradient. For this purpose we consider the Paschen-Back regime (strong magnetic field) and employ a high-field approximation in this treatment. We show the possibility to suppress the unwanted coupling between the electron spins by appropriately swapping states between electronic and nuclear spins. The feasibility of generating the required high magnetic field is discussed.

description: We establish global Gaussian estimates for the Green's matrix of divergence form, second order parabolic systems in a cylindrical domain under the assumption that weak solutions of the system vanishing on a portion of the boundary satisfy a certain local boundedness estimate and a local Hölder estimate. From these estimates, we also derive global estimates for the Green's matrix for elliptic systems with bounded measurable coefficients in two dimensional domains. We present a unified approach valid for both the scalar and vectorial cases and discuss several applications of our result.

description: The nucleus-nucleus interaction potential has been studied within the relativistic mean field theory. The systematics of the relativistic effects have been investigated by analyzing the relation between the potential and the bombarding energy as a function of the impact parameter. It is shown that the potential barriers are noticeably sensitive to the bombarding energy for a given impact parameter. At large bombarding energies the slope at the potential edge decreases with the impact parameter. Comparisons with a non-relativistic treatment shows that relativistic effects cannot be ignored at bombarding energies around and larger than 100 MeV/nucleon.
