description: We develop a stochastic approach to study scalar field fluctuations of the inflaton field in an early inflationary universe with a black-hole (BH), which is described by an effective 4D SdS metric. Considering a 5D Ricci-flat SdS static metric, we implement a planar coordinate transformation, in order to obtain a 5D cosmological metric, from which the effective 4D SdS metric can be induced on a 4D hypersurface. We found that at the end of inflation, the squared fluctuations of the inflaton field are not exactly scale independent and becomes sensitive with the mass of the BH.

description: We study the lepton sector of a four generations model based on the discrete flavor group $A_5$ (the even permutation of five objects). The best features of the three family $A_4$ model survive, including the tribimaximal pattern of three generation neutrino mixings. At leading order the three light neutrino mass relations of $m_{ν_1} = m_{ν_3}$ and $m_{ν_2} = 0$ are predicted. The splitting of the neutrino masses can be naturally obtained as a result of the breaking of $A_{5}$ down to $A_4$ and a degenerate spectrum is preferred in our model. In our $A_5$ model, the electron mass is zero at tree level, but calculable through quantum corrections.

description: Known results on two-dimensional quantum electrodynamics (QED_2) have been used to study the dependence of functional renormalization group equations on renormalization schemes and approximations applied for its bosonized version. It is demonstrated that the singularity of flow equations can be avoided in the optimized and power-law schemes for the bosonized model and the drawback of renormalization on bosonization is shown: it is indicated that renormalization of QED_2 possibly requires interaction terms corresponding to higher frequency modes of its bosonized version.

HP1-mediated transcriptional silencing of ERVs and genes in mouse embryonic stem cells
Creators: name: Jensen, Kristoffer Nyquist
Publisher: name: University of British Columbia
Year: 2020

description: The three mammalian Heterochromatin Protein 1 (HP1) proteins are considered hallmarks of H3K9me3-marked heterochromatin, and are essential for establishing this transcriptionally silent chromatin state genome-wide. They also have a proposed involvement in regulating H3K9me3 levels, based on their interaction with histone lysine methyltransferases. However, they have individually been shown to not be integral for silencing of certain classes of endogenous retroviruses (ERVs). I show that HP1 isoforms in mESCs are functionally redundant and only upon deletion of all three isoforms is there a loss of ERV silencing. I also show that although there are some minor effects on H3K9me3 levels genome-wide following HP1 protein depletion, there are minimal effects on this mark over genes and ERVs, unlike the effects seen on the H3K9me3- and HP1-dependent mark H4K20me3. I also investigate two reported HP1-interacting proteins, AHDC1 and CHAMP1, for their impact on gene regulation and pluripotency maintenance in mESCs. I identify gene promoters where HP1 isoforms are bound independently of H3K9me3, and therefore hypothesize that AHDC1 and CHAMP1 are responsible for HP1 protein recruitment to these promoters via their putative DNA-binding motifs. Both AHDC1 and CHAMP1 have associated severe neurodevelopmental phenotypes when mutated in humans, which could be caused by disruption of HP1-mediated gene silencing and aberrant stem cell differentiation patterns. However, I find no significant effect on gene regulation upon disruption of these two genes in mESCs. I also find no observed effect on cell growth or differentiation potentials of Ahdc1 and Champ1 KO cells. The observed neurodevelopmental phenotypes in humans can therefore not be explained by disruption of HP1-mediated gene silencing in mESCs, although it is still possible they are caused by failure of this mechanism in differentiated cells at later developmental stages.

Superfluid, solid, and supersolid phases of dipolar bosons in a quasi-one-dimensional optical lattice

description: We discuss a model of dipolar bosons trapped in a weakly coupled planar array of one-dimensional tubes. We consider the situation where the dipolar moments are aligned by an external field, and find a rich phase diagram as a function of the angle of this field exhibiting quantum phase transitions between solid, superfluid and supersolid phases. In the low energy limit, the model turns out to be identical to one describing quasi-one-dimensional superconductivity in condensed matter systems. This opens the possibility of using bosons as a quantum analogue simulator of electronic systems, a scenario arising from the intricate relation between statistics and interactions in quasi-one-dimensional systems.

Based on our calculations, we design and synthesize a series of alloys, CoMnGe_{1-x}P_{x}, to experimentally demonstrate the validity of the model. Unusually, we predict and prepare several metamagnets from two ferromagnetic end-members, thus demonstrating a new example of how to vary crystal structure, within the Pnma symmetry group, to provide highly tunable metamagnetism.

description: Bennett and Schumacher's postselected quantum teleportation is a model of closed timelike curves (CTCs) that leads to results physically different from Deutsch's model. We show that even a single qubit passing through a postselected CTC (P-CTC) is sufficient to do any postselected quantum measurement, and we discuss an important difference between "Deutschian" CTCs (D-CTCs) and P-CTCs in which the future existence of a P-CTC might affect the present outcome of an experiment. Then, based on a suggestion of Bennett and Smith, we explicitly show how a party assisted by P-CTCs can distinguish a set of linearly independent quantum states, and we prove that it is not possible for such a party to distinguish a set of linearly dependent states. The power of P-CTCs is thus weaker than that of D-CTCs because the Holevo bound still applies to circuits using them regardless of their ability to conspire in violating the uncertainty principle. We then discuss how different notions of a quantum mixture that are indistinguishable in linear quantum mechanics lead to dramatically differing conclusions in a nonlinear quantum mechanics involving P-CTCs. Finally, we give explicit circuit constructions that can efficiently factor integers, efficiently solve any decision problem in the intersection of NP and coNP, and probabilistically solve any decision problem in NP. These circuits accomplish these tasks with just one qubit traveling back in time, and they exploit the ability of postselected closed timelike curves to create grandfather paradoxes for invalid answers.

A High-Resolution Three-Dimensional Model of the Solar Photosphere Derived from Hinode Observations

Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: A new three-dimensional model of the solar photosphere is presented in this paper and made publicly available to the community. This model has the peculiarity that it has been obtained by inverting spectro-polarimetric observations, rather than from numerical radiation hydrodynamical simulations. The data used here are from the spectro-polarimeter onboard the Hinode satellite, which routinely delivers Stokes I, Q, U and V profiles in the 6302 A spectral region with excellent quality, stability and spatial resolution (approximately 0.3"). With such spatial resolution, the major granular components are well resolved, which implies that the derived model needs no micro- or macro-turbulence to properly fit the widths of the observed spectral lines. Not only this model fits the observed data used for its construction, but it can also fit previous solar atlas observations satisfactorily.

description: A resolution of the St. Petersburg paradox is presented. In contrast to the standard resolution, utility is not required. Instead, the time-average performance of the lottery is computed. The final result can be phrased mathematically identically to Daniel Bernoulli's resolution, which uses logarithmic utility, but is derived using a conceptually different argument. The advantage of the time resolution is the elimination of arbitrary utility functions.

description: The accretion-induced collapse (AIC) of a white dwarf to form a neutron star can leave behind a rotationally supported disk with mass of up to ~ 0.1 M_sun. The disk is initially composed of free nucleons but as it accretes and spreads to larger radii, the free nucleons recombine to form helium, releasing sufficient energy to unbind the remaining disk. Most of the ejected mass fuses to form Ni56 and other iron group elements. We present spherically symmetric radiative transfer calculations of the transient powered by the radioactive heating of this ejecta. For an ejecta mass of 1e-2 M_sun (3e-3 M_sun), the lightcurve peaks after

description: Steeping interest on graphene research in basic sciences and applications emphasizes the need for an economical means of synthesizing it. We report a method for the synthesis of graphene on commercially available stainless steel foils using direct thermal chemical vapor deposition. Our method of synthesis and the use of relatively cheap precursors such as ethanol (CH3CH2OH) as a source of carbon and SS 304 as the substrate, proved to be economically viable. Presence of single- and few-layer graphene was confirmed using confocal Raman microscopy/spectroscopy. X-ray photoelectron spectroscopic measurements were further used to establish the influence of various elemental species present in stainless steel on graphene growth. Role of cooling rate on surface migration of certain chemical species (oxides of Fe, Cr and Mn) that promote or hinder the growth of graphene is probed. Such analysis of the chemical species present on the surface can be promising for graphene based catalytic research.

description: The prehistoric Australian conifer Wollemia nobilis was thought to be extinct until the discovery of living specimens in 1992. Due to its threatened status and restricted distribution, investigations into its metabolic constituents have been limited. Chapter 2 details the phytochemical investigation of Wollemia nobilis. Crude organic extracts from the leaves Wollemia nobilis collected on UBC campus were screened for bioactivity against a series of pathogens. Bioassay guided fractionation led to the isolation and structural elucidation of the novel compound 2.12, which upon examination of the experimental data was found to be the true structure of the previously reported compound wollemolide (2.11). Additionally, two new endoperoxide diterpenoids (2.14 & 2.15), several known compounds new to the Wollemia genus (2.13 & 2.16-2.18), as well as sandaracopimaric acid (2.4) previously reported from Wollemia nobilis were isolated and structurally elucidated. The pure compounds demonstrated no in vitro activity against the screened pathogens Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Candida albicans and methicillin resistant Staphylococcus aureus (MRSA). The Indonesian sponge Petrosia contignata has been the source of several novel bioactive metabolites. Though previously examined, the crude sponge extracts of Petrosia contignata were investigated for less abundant metabolites. Chapter 3 describes the isolation and structural elucidation of the new tetrahydroxylated steroid petrosiasterol (3.9). as well as three known steroids new to the Petrosia genus (3.7, 3.8, & 3.11) and one previously reported from the Petrosia genus (3.10).

We extend the evaluation to non-Abelian gauge groups and multi-flavors. We also compare our results with the volume of the Kahler quotient space inspired by the brane configuration.

description: Context. The trans-neptunian region of the Solar System is populated by a large variety of icy bodies showing great diversity in orbital behavior, size, surface color and composition. One can also note the presence of dynamical families and binary systems. One surprising feature detected in the spectra of some of the largest Trans-Neptunians is the presence of crystalline water-ice. This is the case for the large TNO (136 108) Haumea (2003 EL61). Aims. We seek to constrain the state of the water ice of Haumea and its satellites, and investigate possible energy sources to maintain the water ice in its crystalline form. Methods. Spectro-imaging observations in the near infrared have been performed with the integral field spectrograph SINFONI mounted on UT4 at the ESO Very Large Telescope. The spectra of both Haumea and its larger satellite Hi'iaka are analyzed. Relative astrometry of the components is also performed, providing a check of the orbital solutions and equinox seasons. Results. We describe the physical characteristics of the crystalline water-ice present on the surface of Haumea and its largest satellite Hi'iaka and analyze possible sources of heating to maintain water in crystalline state: tidal dissipation in the system components vs radiogenic source. The surface of Hi'iaka appears to be covered by large grains of water ice, almost entirely in its crystalline form. Under some restricted conditions, both radiogenic heating and tidal forces between Haumea and Hi'iaka could provide the energy sufficient to maintain the ice in its crystalline state. Based on observations collected at the European SouthernObservatory, Paranal, Chile - 60.A-9235

description: Unambiguous detection of the tidal disruption of a star would allow an assessment of the presence and masses of supermassive black holes in quiescent galaxies. It would also provide invaluable information on bulge scale stellar processes (such as two-body relaxation) via the rate at which stars are injected into the tidal sphere of influence of the black holes. This rate, in turn, is essential to predict gravitational radiation emission by compact object inspirals. The signature of a tidal disruption event is thought to be a fallback rate for the stellar debris onto the black hole that decreases as $t^{-5/3}$. This mass flux is often assumed to yield a luminous signal that decreases in time at the same rate. In this paper, we calculate the monochromatic lightcurves arising from such an accretion event. Differently from previous studies, we adopt a more realistic description of the fallback rate and of the super-Eddigton accretion physics. We also provide simultaneous lightcurves in optical, UV and X-rays. We show that, after a few months, optical and UV lightcurves scale as $t^{-5/12}$, and are thus substantially flatter than the $t^{-5/3}$ behaviour, which is a prerogative of the bolometric lightcurve, only. At earlier times and for black hole masses $< 10^7 M_{\sun}$, the wind emission dominates: after reaching a peak of $10^{41}-10^{43}$ erg/s at roughly a month, the lightcurve decreases steeply as $\sim t^{-2.6}$, until the disc contribution takes over. The X-ray band, instead, is the best place to detect the $t^{-5/3}$ "smoking gun" behaviour, although it is displayed only for roughly a year, before the emission steepens exponentially.

Randall-Sundrum Corrections to the Width Difference and CP-Violating Phase in $B^0_s$-Meson Decays

description: We study the impact of the Randall-Sundrum setup on the width difference $ΔΓ_s$ and the CP-violating phase $ϕ_s$ in the $\bar B_s^0$-$B_s^0$ system. Our calculations are performed in the general framework of an effective theory, based on operator product expansion. The result can thus be used for many new physics models. We find that the correction to the magnitude of the decay amplitude $Γ_{12}$ is below 4% for a realistic choice of input parameters. The main modification in the $ΔΓ_s/β_s$-plane is caused by a new CP-violating phase in the mixing amplitude, which allows for a better agreement with the experimental results of CDF and DØfrom $B_s^0\rightarrow J/ψϕ\,$ decays. The best-fit value of the CP asymmetry $S_{ψϕ}$ can be reproduced, while simultaneously the theoretical prediction for the semileptonic CP asymmetry $A_{\rm SL}^s$ can enter the $1σ$ range.

Preparation for and implementation of a physical activity education program (PEP) in a primary care setting
Creators: name: Guzman, Gabriella
Publisher: name: No Publisher Supplied
Year: 2021

description: Background: Physical activity is one of the most important behaviors that humans can engage in to improve their health, yet population rates of physical activity remain considerably low. Additional research on physical activity interventions is necessary, specifically group-based interventions in primary care. Purpose: The purpose of this study was to design and provide an illustration of a group-based physical activity intervention in primary care, called the Physical Activity Education Program (PEP). The aim of Phase 1 was to gather qualitative information from primary care physicians (PCPs) and patients to assist in designing PEP. The aim of Phase 2 was to implement a pilot PEP program and assess its acceptability, feasibility, and impact on physical activity and health outcomes. Methods: PCPs and patients from a family medicine practice (FMMS) were recruited to participate in Phase 1 key informant interviews. The four-week PEP program was implemented in Phase 2. Four patients from FMMS were recruited over the span of a month to participate. The first PEP session occurred in-person, after which the program continued virtually in response to social distancing measures put in place during the COVID-19 pandemic. Case descriptions for each participant were used to illustrate the feasibility, acceptability and impact of PEP. Results: Phase 1 key informant interviews helped design the PEP program. Of the four PEP participants, two (50%) completed the program. The PEP program was found to be very satisfactory by completers; satisfaction was slightly lower among non-completers. Physical activity engagement was shown to increase among completers by the end of PEP; at follow-up, physical activity remained at similar levels or higher. Depressive, anxiety, and somatic symptoms decreased among all participants by the end of PEP; one completer exhibited an increase in symptoms at follow-up. Conclusions: This study indicated that implementing a multi-disciplinary, group-based physical activity intervention in primary care is possible. Although the sample size was very small, the impact that the PEP program has on physical activity and health outcomes is promising. Future research is necessary to better understand the feasibility and acceptability of in-person and virtual group-based physical activity interventions in primary care.

description: MAN1B1-CDG is a multisystem disorder caused by mutations in MAN1B1, encoding the endoplasmic reticulum mannosyl-oligosaccharide alpha-1,2-mannnosidase. A defect leads to dysfunction within the degradation of misfolded glycoproteins. We present two additional patients with MAN1B1-CDG and a resulting defect in endoplasmic reticulum-associated protein degradation. One patient (P2) is carrying the previously undescribed p.E663K mutation. A therapeutic trial in patient 1 (P1) using disulfiram with the rationale to generate an attenuation of translation and thus a balanced, restored ER glycoprotein synthesis failed. No improvement of the transferrin glycosylation profile was seen.

Exploring the interactome of the bacterial Sec translocon
Creators: name: Young, John William
Publisher: name: University of British Columbia
Year: 2024

description: Many periplasmic and extracellular Escherichia coli (E. coli) proteins are transported across the inner bacterial membrane through the highly conserved heterotrimeric SecYEG protein-conducting channel. During post-translational translocation, polypeptide substrates are driven across the membrane through SecYEG by the ATPase SecA, which binds to SecYEG and couples nucleotide hydrolysis to polypeptide movement. In the first part of this thesis, we study the dynamics of SecYEG-SecA interactions. We show that SecA is a highly dynamic enzyme, repeatedly binding to and dissociating from SecYEG during substrate translocation. Using two model Sec-dependent protein substrates, we show that the importance of these dynamics for efficient translocation depends on the length of the translocating protein substrate. In the second part of this thesis, we turn to quantitative proteomics to identify novel interactors of the SecYEG complex. Previous studies have identified and validated a series of membrane embedded interactors of SecYEG using classical detergent-based methods. However, it is possible that other important interactors of the Sec translocon may exist which have not yet been identified by detergent-based proteomic methods - the difficulties of using detergent-based methods to identify and characterize transient interactors of membrane proteins and complexes are well-documented. Here, we employ the peptidisc - a "one-size-fits-all" membrane mimetic - to identify and characterize potentially novel interactors of the Sec translocon in detergent-free conditions. One of the most notable interactions identified in this work is a super-complex between the Sec translocon and the outer membrane embedded Bam complex, which is required for insertion of outer membrane proteins (OMPs). This observation is particularly astonishing and has implications for our understanding of outer membrane protein biogenesis. Finally, we develop a functionalized variant of the peptidisc scaffold and demonstrate its utility for isolation of the membrane proteome. As a simple case study, we employ the functionalized peptidisc scaffold to survey changes in the membrane proteome caused by altered gene expression. Potential future applications of the peptidisc membrane mimetic in the fields of membrane protein biochemistry and membrane proteomics will also be discussed.

description: In this paper we explore the concept of hierarchy as a quantifiable descriptor of ordered structures, departing from the definition of three conditions to be satisfied for a hierarchical structure: {\em order}, {\em predictability} and {\em pyramidal structure}. According to these principles we define a hierarchical index taking concepts from graph and information theory. This estimator allows to quantify the hierarchical character of any system susceptible to be abstracted in a feedforward causal graph, i.e., a directed acyclic graph defined in a single connected structure. Our hierarchical index is a balance between this predictability and pyramidal condition by the definition of two entropies: one attending the onward flow and other for the backward reversion. We show how this index allows to identify hierarchical, anti-hierarchical and non hierarchical structures. Our formalism reveals that departing from the defined conditions for a hierarchical structure, feedforward trees and the inverted tree graphs emerge as the only causal structures of maximal hierarchical and anti-hierarchical systems, respectively. Conversely, null values of the hierarchical index are attributed to a number of different configuration networks; from linear chains, due to their lack of pyramid structure, to full-connected feedforward graphs where the diversity of onward pathways is canceled by the uncertainty (lack of predictability) when going backwards. Some illustrative examples are provided for the distinction among these three types of hierarchical causal graphs.

description: In this work we investigate 1+2 reactions within the framework of the hyperspherical adiabatic expansion method. To this aim two integral relations, derived from the Kohn variational principle, are used. A detailed derivation of these relations is shown. The expressions derived are general, not restricted to relative $s$ partial waves, and with applicability in multichannel reactions. The convergence of the ${\cal K}$-matrix in terms of the adiabatic potentials is investigated. Together with a simple model case used as a test for the method, we show results for the collision of a $^4$He atom on a \dimer dimer (only the elastic channel open), and for collisions involving a $^6$Li and two $^4$He atoms (two channels open).

Measurement of non-commuting spin components using spin-orbit interaction

description: We analyze the physical meaning of a possible experiment aimed at the simultaneous measurement of two non-commuting spin components. We demonstrate that switching of a strong spin-orbit interaction, e.g., in a solid state or a cold-atom system, for a short period of time simulates a simultaneous von Neumann measurement of spin components, $σ_x$ and $σ_y$. By mapping spin dynamics onto coordinate-space motion, such a measurement determines time averages of $σ_x$ and $σ_y$ which, unlike their instantaneous values, may be evaluated simultaneously to an arbitrary accuracy.
