description: Statistical mechanics provides an elegant explanation to the appearance of coherent structures in two-dimensional inviscid turbulence: while the fine-grained vorticity field, described by the Euler equation, becomes more and more filamented through time, its dynamical evolution is constrained by some global conservation laws (energy, Casimir invariants). As a consequence, the coarse-grained vorticity field can be predicted through standard statistical mechanics arguments (relying on the Hamiltonian structure of the two-dimensional Euler flow), for any given set of the integral constraints. It has been suggested that the theory applies equally well to geophysical turbulence; specifically in the case of the quasi-geostrophic equations, with potential vorticity playing the role of the advected quantity. In this study, we demonstrate analytically that the Miller-Robert-Sommeria theory leads to non-trivial statistical equilibria for quasi-geostrophic flows on a rotating sphere, with or without bottom topography. We first consider flows without bottom topography and with an infinite Rossby deformation radius, with and without conservation of angular momentum. When the conservation of angular momentum is taken into account, we report a case of second order phase transition associated with spontaneous symmetry breaking. In a second step, we treat the general case of a flow with an arbitrary bottom topography and a finite Rossby deformation radius. Previous studies were restricted to flows in a planar domain with fixed or periodic boundary conditions with a beta-effect. In these different cases, we are able to classify the statistical equilibria for the large-scale flow through their sole macroscopic features. We build the phase diagrams of the system and discuss the relations of the various statistical ensembles.

description: Software product line (SPL) scoping is an important phase when planning for product line adoption. An SPL scope specifies: (1) the extent of the domain supported by the product line, (2) portfolio of products in the product line and (3) list of assets to be developed for reuse across the family of products. An important challenge with SPL scope planning is how estimates may affect the robustness of plans. Scope plans are usually based on estimates about the state of the market and the engineering capabilities of the development team. These estimates are prone to inaccuracy due to the uncertainty in the environment or the measurement accuracy. Therefore, plans based on these estimates may lose optimality or even become infeasible when estimates are inaccurate. To address the above, we propose to include uncertainty as part of the SPL scoping model. Plans developed in consideration of uncertainty would be more robust against possible fluctuations in estimates. In this research, a method to incorporate uncertainty in scoping optimization and its application to generate robust solutions is proposed. We capture uncertainty as part of the formulation and model scoping optimization as a multi-objective problem with profit and stability as fitness functions. More specifically, profit stability and feasibility stability are considered to represent uncertainty concerns. To measure the effectiveness of our proposal and evaluate its validity, a number of different experiments are conducted. Results show that, compared to other scope optimization approaches, both profit stability and feasibility stability are improved while maintaining near-optimal performance for profit objective. Also, generated results consist of solutions with trade-offs between profit and stability, providing the decision maker with enhanced decision support. Multi-objective optimization with stability consideration for SPL scoping provides project managers with a robust and flexible way to address uncertainty in the process of SPL scoping.

description: Upper Cretaceous strata outcropping in the vicinity of Laguna Figueroa, southern Chile record the sedimentary processes of a deep-water, slope channel depositional setting within the Magallanes foreland basin. The strata investigated is exposed over a 6 km long by 100 m thick depositional dip-oriented outcrop, which is cross cut by numerous gullies that provide strike perspectives. Measured sections, paleoflow measurements, photomosaic interpretations, and geo-referenced stratigraphic surfaces are used to construct a 3-D digital outcrop-based model that consists of a hierarchy of channelform sedimentary bodies. Five mappable channel elements, 10-20 m thick, comprise a single 60 m thick channel complex. The succession of channel element deposits transition from laterally offset to more vertically aligned down-slope over 2 km. Similar architectural transitions are common to conduits that transect topographically complex slope systems on numerous continental margins, including petroliferous regions of west Africa and the Nile Delta.

description: This article is an attempt to provide a self consistent picture, including existence analysis and numerical solution algorithms, of the mathematical problems arising from modeling photocurrent transients in Organic-polymer Solar Cells (OSCs). The mathematical model for OSCs consists of a system of nonlinear diffusion-reaction partial differential equations (PDEs) with electrostatic convection, coupled to a kinetic ordinary differential equation (ODE). We propose a suitable reformulation of the model that allows us to prove the existence of a solution in both stationary and transient conditions and to better highlight the role of exciton dynamics in determining the device turn-on time. For the numerical treatment of the problem, we carry out a temporal semi-discretization using an implicit adaptive method, and the resulting sequence of differential subproblems is linearized using the Newton-Raphson method with inexact evaluation of the Jacobian. Then, we use exponentially fitted finite elements for the spatial discretization, and we carry out a thorough validation of the computational model by extensively investigating the impact of the model parameters on photocurrent transient times.

description: Teams continue to increase in popularity within the workplace given their potential for levels of performance above that possible with individuals alone. Due to an ever-changing workforce, teams are susceptible to membership change, defined in this study as current members leaving the team and new members joining. In order to succeed, teams must adapt. This study investigated the role of Behavioural Integration (BI) in differentiating between teams on team performance, satisfaction and perceptions of learning. Using multilevel growth modeling, results indicated that guests’ BI was not a reliable predictor of team performance, however, it was positively related to the starting intercept for satisfaction. Supplemental analyses identified individual’s perceptions of social identity and psychological safety as significantly reliable predictors of subsequent individual perceptions of BI. The implications of these results are discussed, as well as an in-depth look at Behavioral Integration as a future mediator in our current team process models.

description: We demonstrate that long-range interactions can cause, as time evolves, consecutive reversals of directed currents for dilute ensembles of particles in driven lattices. These current-reversals are based on a general mechanism which leads to an interaction-induced accumulation of particles in the regular regions of the underlying single-particle phase space and to a synchronized single-particle motion as well as an enhanced efficiency of Hamiltonian ratchets.

description: A Reunião de Reflexão sobre Financiamento da Inovação Disruptiva teve como objetivo debater possíveis formas de avaliação e de financiamento dos medicamentos de grau de inovação disruptiva que assegurem o seu rápido e efetivo acesso ao mercado e aos doentes. De facto, novas opções terapêuticas em determinadas áreas podem constituir uma verdadeira quebra com práticas do passado. Esquemas de tratamento, progressão das doenças e características epidemiológicas podem ser absolutamente revolucionados quando surja uma opção terapêutica que mude radicalmente o curso natural da evolução da doença. São estes casos que entendemos que justificam repensar todo o sistema de avaliação, e também de financiamento, de modo a otimizar todo o benefício potencial que o SNS e os cidadãos podem extrair de determinado fármaco que apresente as características atrás descritas.
No decorrer da reunião foram debatidos alguns aspetos relativos aos constrangimentos e estrangulamentos no atual sistema de avaliação e financiamento, tendo sido sugeridas diversas melhorias ao funcionamento do sistema.
A reunião contou com a participação ativa e a opinião de todos os intervenientes. Este documento foi objeto de revisão e aprovação por parte dos participantes na reunião, tendo sido a sua redação final o resultado da discussão presencial e de um processo de consulta posterior realizado com o objetivo de elaborar um documento consensual.

description: We present the Hit Backspace Once More (HBOM) method for correcting a measurement for the effect of an imperfect detector. The HBOM method is a model-independent and potentially data-driven technique that repeatedly applies a parameterisation of the detector effect to observed data. The correction is determined by extrapolating the data so-obtained to a detector effect of zero. We demonstrate this technique using the two particle correlation function, which is an observable that can otherwise be difficult to correct for systematic shifts introduced by the detector.

Titin Regulation of Active and Passive Force in Skeletal Muscle

Year: 2015
Subjects: subject: Engineering--Biomedical
subject: Muscle
subject: Titin

description: History dependent properties of muscle contraction such as force enhancement and force depression are not readily explainable by contemporary theories describing how muscles function. The lack of clear mechanistic understanding makes these phenomena difficult to reconcile within the current muscle framework of the sliding filament and crossbridge theories. Experimental evidence has been mounting however, to overturn this antiquated two filament (actin and myosin) based paradigm for one that incorporates a third filament called titin which may serve to explain history dependence. Evidence now suggests that titin can increase its stiffness in response to contractile conditions, thus being critically involved in both passive (low calcium) and active (high calcium) muscle function. The mechanisms behind this are still debated, but two potential ideas for titin based force regulation during active stretch are: (A) an increase in the inherent stiffness of the molecular chain through calcium binding to titin immunoglobulin (Ig) domains or (B) a decrease in titin’s elastic length via transient attachment to actin. Our Ig domain work indicated that calcium had a biochemical effect that further manifested in a mechanical stiffening when Ig domains were stretched with an atomic force microscope in the presence of calcium. The magnitude of this calcium stiffening was about 20 % which lends support to this titin-based stiffening being important for active muscle contraction. Titin-actin interaction was investigated by fluorescently labeling sites on titin within muscle myofibrils where this interaction was speculated to occur. Upon muscle activation, no titin-actin interaction was seen, but rather unexpectedly a titin myosin interaction consistently developed. This led to the formulation of our Titin Entanglement Hypothesis based on observations of entangled I-band titin segments with myosin crossbridges during periods of spatial overlap between the two. This rendered the spring abbreviated and thus able to generate more force upon active stretch, until a release threshold was reached. This entanglement mechanism along with calcium stiffening of Ig domains has the potential to explain the history dependent properties mentioned above, and may serve to help understand the role of titin in active muscle contraction.

description: Published data from long-term observations of a strip of sky at declination +5 degrees carried out at 7.6 cm on the RATAN-600 radio telescope are used to estimate some statistical properties of radio sources. Limits on the sensitivity of the survey due to noise imposed by background sources, which dominates the radiometer sensitivity, are refined. The vast majority of noise due to background sources is associated with known radio sources (for example, from the NVSS with a detection threshold of 2.3 mJy) with normal steep spectra (α = 0.7-0.8, S \propto ν^{- α}), which have also been detected in new deep surveys at decimeter wavelengths. When all such objects are removed from the observational data, this leaves another noise component that is observed to be roughly identical in independent groups of observations. We suggest this represents a new population of radio sources that are not present in known catalogs at the 0.6 mJy level at 7.6 cm. The studied redshift dependence of the number of steep-spectrum objects shows that the sensitivity of our survey is sufficient to detect powerful FRII radio sources at any redshift, right to the epoch of formation of the first galaxies. The inferred new population is most likely associated with low-luminosity objects at redshifts z < 1. In spite of the appearance of new means of carrying out direct studies of distant galaxies, searches for objects with very high redshifts among steep and ultra-steep spectrum radio sources remains an effective method for studying the early Universe.

description: We study the existence and stability of multibreathers in Klein-Gordon chains with interactions that are not restricted to nearest neighbors. We provide a general framework where such long range effects can be taken into consideration for arbitrarily varying (as a function of the node distance) linear couplings between arbitrary sets of neighbors in the chain. By examining special case examples such as three-site breathers with next-nearest-neighbors, we find {\it crucial} modifications to the nearest-neighbor picture of one-dimensional oscillators being excited either in- or anti-phase. Configurations with nontrivial phase profiles, arise, as well as spontaneous symmetry breaking (pitchfork) bifurcations, when these states emerge from (or collide with) the ones with standard (0 or $π$) phase difference profiles. Similar bifurcations, both of the supercritical and of the subcritical type emerge when examining four-site breathers with either next-nearest-neighbor or even interactions with the three-nearest one-dimensional neighbors. The latter setting can be thought of as a prototype for the two-dimensional building block, namely a square of lattice nodes, which is also examined. Our analytical predictions are found to be in very good agreement with numerical results.

description: Naphthenic acids (NAs), carboxylic acids with large aliphatic tail groups, are an important class of oil sands tailings pond toxins. In this study, the effects of a mixture of model NAs on the pond snail Lymnaea stagnalis were examined during various life stages. Hatching rate was progressively affected over a range of 20-75 mg/L NAs, while embryo somatic growth was progressively affected over a range of 30-75 mg/L NAs. My data also provides evidence that NA molecular geometry is a factor in selective permeability of NAs into Lymnaea’s gelatinous egg masses. Adult survival, growth, feeding, fecundity and behavior were progressively affected over a range of 10-50 mg/L NAs, but not at 0.1-4 mg/L NAs. Taken together, my data support the conclusion that low molecular weight NAs have a negative impact on various physiological and behavioral aspects of this freshwater gastropod that escalates over a range of environmentally realistic doses.

description: Abstract

The aim of this study is to identify and evaluate existing research on nutritional interventions for individuals with Autism Spectrum Disorder (ASD). The study followed the research approach for conducting an integrative review. Two researchers independently searched the PubMed, Scopus and Google Scholar databases for relevant literature. Using carefully developed search terms, 102 articles were selected from these databases. After reading the full text of 67 articles, the reviewers selected 33 studies that were eligible for inclusion.  Based on the findings of this review, individuals with ASD have been treated with various nutritional interventions, including gluten-free, casein-free diets, ketogenic diets, specific carbohydrate diets, prebiotics and probiotic supplements, as well as vitamins and minerals. These interventions have resulted in improvements in cognition, sociability, and behavioral symptoms associated with ASD. Furthermore, these interventions also resulted in improvements in gastrointestinal symptoms, adaptive functioning, sensory profiles, quality of life, nutritional status, emotional, and intellectual aspects of life for individuals with ASD. Whereas the existing literature suggests potential benefits, further research is needed to clearly understand the effectiveness and potential risks associated with these nutritional interventions among individuals with ASD. The authors highlighted the research and clinical implications of nutritional interventions when working with individuals with ASD.
Automatic 3D Building Model Generation by Integrating LiDAR and Aerial Images Using a Hybrid Approach

description: The development of sensor technologies and the increase in user requirements have resulted in many different approaches for efficient building model generation. Three-dimensional building models are important in various applications, such as disaster management and urban planning. Despite this importance, generation of these models lacks economical and reliable techniques which take advantage of the available multi-sensory data from single and multiple platforms. Therefore, this research develops a framework for fully-automated building model generation by integrating data-driven and model-driven methods as well as exploiting the advantages of images and LiDAR datasets. The building model generation starts by employing LiDAR data for building detection and approximate boundary determination. The generated building boundaries are then integrated into a model-based image processing strategy, because LiDAR derived planes show irregular boundaries due to the nature of LiDAR point acquisition. The focus of the research is generating models for the buildings with right-angled-corners, which can be described with a collection of rectangles (e.g., L-shape, T-shape, U-shape, gable roofs, and more complex building shapes which are combinations of the aforementioned shapes), under the assumption that the majority of the buildings in urban areas belong to this category. Therefore, by applying the Minimum Bounding Rectangle (MBR) algorithm recursively, the LiDAR boundaries are decomposed into sets of rectangles for further processing. At the same time the quality of the MBRs are examined to verify that the buildings, from which the boundaries are generated, are buildings with right-angled-corners. These rectangles are preliminary model primitives. The parameters that define the model primitives are adjusted using detected edges in the imagery through the least-squares adjustment procedure, i.e., model-based image fitting. The level of detail in the final Digital Building Model is based on the number of recursions during the MBR processing, which in turn are determined by the LiDAR point density. The model-based image fitting refines the search space and resolves the matching ambiguities in multiple images, which results in higher quality boundaries. This research thus develops an approach which not only automates the building model generation, but also improves the accuracy of the building model itself.

description: We present the results from a detailed analysis of photometric and spectrophotometric data on five Seyfert 1 galaxies observed as a part of a recent reverberation mapping program. The data were collected at several observatories over a 140-day span beginning in 2010 August and ending in 2011 January. We obtained high sampling-rate light curves for Mrk 335, Mrk 1501, 3C120, Mrk 6, and PG2130+099, from which we have measured the time lag between variations in the 5100 Angstrom continuum and the H-beta broad emission line. We then used these measurements to calculate the mass of the supermassive black hole at the center of each of these galaxies. Our new measurements substantially improve previous measurements of MBH and the size of the broad line-emitting region for four sources and add a measurement for one new object. Our new measurements are consistent with photoionization physics regulating the location of the broad line region in active galactic nuclei.

description: This report is relevant for the integration of knowledge and actions of all three stakeholders’ groups. It contains a Data collating plan which documents the choices made to allow collating data from different data sources.This data collating plan feeds into the broader objectives of task 4.2 which is: Evaluating and selecting open access data sources useful for farmers, actors in the value chains and policy makers and to inform farm management and policy and investment decisions related to soil, land health, climate, biodiversity and sustainable farming.The aim is to create a central space where relevant data on agroforestry can easily be found and accessed, through permanent links. The Tools and data catalogue is available on the DigitAF website: https://digitaf.eu/tools-and-data-catalogue/ and will be updated and populated with more datasets until the end of the project and beyond. The Data Catalogue will include: 1) regional agroforestry data with data on agroforestry systems, practices, tree and crop species; 2) data applicable on a wider scale, for instance spatial and biophysical databases containing data on e.g. land cover, soil, climate, erosion, wetness, or nutrient loads, 3) a catalogue of agroforestry-related projects (see image on first page). The DigitAF Data Catalogue is the result of a collaboration across multiple work packages. Early 2023, DigitAF project partners made a first inventory of potentially interesting datasets relevant for agroforestry. This inventory listed 71 data source topics or real existing datasets which would be important for the living labs involved in the project or for completing a specific project task. Hereafter, datasets have been added to complete ongoing project work focusing on e.g. agri-environmental indices (Kay et al. 2024) and Trees Outside Forests (WP1). In addition, datasets related to biodiversity, greenhouse gas emissions, carbon and soil health (WP3) have been added to the catalogue. Identifying datasets and making the data open access by uploading to the DigitAF Data Catalogue will continue until the end of the project in collaboration with all project partners, living lab leaders and members, tool developers and a wider community of interest (researchers, farm advisors, farmers).

description: The purpose of this study is to help uncover reasons for women’s low participation rates in the field of skilled trades and apprenticeship in Canada. This thesis analyzes data gained through life history interviews with six recently graduated female apprentices, with the objective being to gain their insights on which experiences and factors may have helped contribute to their successes. This thesis offers an analysis of apprenticeship as a gendered space and process of work-related learning. Framed by concepts developed by Pierre Bourdieu, the findings suggest that the structure of the field of skilled trades and apprenticeship acts to reproduce gender through expected, or “taken-for-granted” characteristics of successful apprentices. The findings also depict skilled trades and apprenticeship as a field dominated by men and masculinity, but one in which the female apprentice can successfully practice by exhibiting a culturally-appropriate vocational habitus while maximizing field-specific capitals.
Radio frequency heating pre-treatment of sub-alpine fir to improve kiln drying
Creators: name: Abubakari, Alhassan
Publisher: name: University of British Columbia
Year: 2010

description: The objective of the study was to reveal the effect of RF heating at different power densities and time combinations as pre-conventional kiln treatment on the drying characteristics and quality of sub-alpine fir lumber. As a consequence of this objective, the study hypothesis was formulated as: “if RF heating improves the permeability of sub-alpine fir, then upon kiln drying, final moisture content variability between and within lumbers as well as drying defects will decrease”. In this research, thirteen groups of one meter long, 51 x 102 mm sub-alpine fir lumbers were RF heated with two power densities (27 and 72 kW/m³) and eight time combinations (15, 30, 45, 60, 75, 90, 105 and 120 minutes), but all to the same final temperature level (100°C) before kiln drying in a two-phase experimental design. Two groups (one for each phase) served as controls. Permeability tests were also performed in the second phase of the study. The effect of RF heating on permeability, drying rates, moisture content gradient, final moisture content variability between pieces and drying defects was evaluated and analyzed. Treatment effect on total energy consumption (sum of RF heating and kiln drying energies) was also assessed to ascertain the feasibility of applying this technology in industrial setting. Data analysis revealed in phase 1 that, not all treatments reduced moisture content variability within and between specimens and improved drying rates above and below fiber saturation point, compared to the control. Defect appearance also did not significantly reduce, and all except two treatments increased total energy consumption. In phase 2 however, permeability improved in all except one treatment but was found not to be statistically significant. Treatments also improved moisture gradient as well as drying rates above and below fiber saturation point but the moisture gradient was found not to be statistically significant. Compared to the control, not all treatments reduced moisture content variability between wood samples. Defects did not significantly improve between treatments and control, and total energy consumption was relatively higher in treatments. Results obtained within the limitations of this study led to the rejection of the hypothesis.

description: Excitation energies and transition probabilities of the first $2^+$ excitations in even tin and lead isotopes as well as the quadrupole moments of odd neighbors of these isotopes are calculated within the self-consistent Theory of Finite Fermi Systems based on the Energy Density Functional by Fayans et al. The effect of the density dependence of the effective pairing interaction is analyzed in detail by comparing results obtained with volume and surface pairing. The effect is found to be noticeable. For example, the $2^+$-energies are systematically higher at 200-300 keV for the volume paring as compared with the surface pairing case. But on the average both models reasonably agree with the data. Quadrupole moments of odd-neutron nuclei are very sensitive to the single-particle energy of the state $λ$ under consideration due to the Bogolyubov factor ($u^2_λ-v^2_λ$). A reasonable agreement with experiment for the quadrupole moments has been obtained for the most part of odd nuclei considered. The method used gives a reliable possibility to predict quadrupole moments of unstable odd nuclei including very neutron rich ones.

description: The mechanisms underlying tissue regeneration span a broad spectrum of distinct yet interconnected biological processes that are largely modulated by tissue resident stem cells and the host immune system. In the skin, epithelial stem cells, the adjacent mesenchyme, and resident immune cells play important roles in regulating adult hair follicle (HF) regeneration. Previous work has uncovered distinct hair follicle stem cell (HFSC) populations responsible for maintaining the epithelial compartments of the HF. However, the cellular dynamics within the mesenchymal compartments of the HF (the dermal sheath and dermal papilla) are less understood. Indeed, how these specialized inductive cells are maintained over successive cycles of regeneration and degeneration is an unresolved question. Through in vivo fate mapping of adult HF dermal sheath (DS) cells, I found that a subset of DS cells is retained following each hair cycle, exhibit self-renewal, and repopulate the DS and dermal papilla (DP) with new cells. In vivo clonal analysis of DS cells revealed that individual DS cells exhibited bipotency and self-renewal, thus providing evidence for the existence of a stem cell within the adult HF mesenchyme. Ablating bipotent HF dermal stem cells (hfDSCs) retarded hair regrowth and altered hair type specification. This work has valuable implications toward restoration of hair growth after injury, disease and aging. Immune cells integral players during wound healing and tissue regeneration. The HF affords a unique model to gain insight into the cellular and molecular mechanisms by which cutaneous macrophages influence stem cell function during tissue regeneration. I took advantage of wound-induced hair growth (WIHG), a phenomenon by which skin injury triggers regeneration of surrounding HFs, to explore the relationship between wound macrophages, HFSCs, and tissue regeneration. Using a variety of transgenic approaches, I show that 8-10 days after injury, CD11b+ CX3CR1hi CCR2+ Ly6Clo macrophages increase the perifollicular concentrations of TGF1, activate epithelial stem/progenitors within the secondary hair germ and ultimately stimulate HF regeneration. Furthermore, WIHG was abolished in mice deficient for CX3CR1 but not CCR2. These findings identify a novel mechanism by which anti-inflammatory macrophages stimulate HFSCs to trigger HF regeneration in response to skin injury.

description: Electron-phonon coupling is central to many condensed matter phenomena. Harnessing these effects for novel material functionality in materials always involves non-equilibrium electronic states, which in turn alter quasi-free-carrier density and screening. Thus, gaining a fundamental understanding of the interplay of carrier screening and electron-phonon coupling is essential for advancing ultrafast science. Prior works have mainly focused on the impact of carrier screening on electronic structure properties. Here we investigate the non-equilibrium lattice dynamics of MoS2 after a photoinduced Mott transition. The experimental data are closely reproduced by ab-initio ultrafast dynamics simulations. We find that the non-thermal diffuse scattering signals in the vicinity of the Bragg peaks, originating from long-wavelength phonon emission, can only be reproduced upon explicitly accounting for the screening of electron-phonon interaction introduced by the Mott transition. These results indicate the screening influences electron-phonon coupling, leading to a suppression of intravalley phonon-assisted carrier relaxation. Overall, the combined experimental and computational approach introduced here offers new prospects for exploring the influence of screening of the electron-phonon interactions and relaxation pathways in driven solids.

description: Active Galactic Nuclei (AGN) are some of the most luminous and extreme environments in the Universe. The central engines of AGN, believed to be super-massive black-holes, are fed by accretion discs threaded by magnetic fields within a dense magneto-ionic medium. We report our findings from polarimetric Very-long-baseline Interferometry (VLBI) observations of quasar NRAO150 taken in October 2022 using a combined network of the Very Long Baseline Array (VLBA) and Effelsberg 100-m Radio Telescope. These observations are the first co-temporal multi-frequency polarimetric VLBI observations of NRAO150 at frequencies above 15GHz. We use the new VLBI polarization calibration procedure, GPCAL, with polarization observations of frequencies of 12GHz, 15GHz, 24GHz, and 43GHz of NRAO150. From these observations, we measure Faraday rotation. Using our measurement of Faraday rotation, we also derive the intrinsic electric vector position angle (EVPA0) for the source. As a complementary measurement we determine the behavior of polarization as a function of observed frequency. The polarization from NRAO150 only comes from the core region, with a peak polarization intensity occurring at 24GHz. Across the core region of NRAO150 we see clear gradients in Faraday rotation and EVPA0 values that are aligned with the direction of the jet curving around the core region. We find that for the majority of the polarized region the polarization fraction is greater at higher frequencies, with intrinsic polarization fractions in the core 3%. The Faraday rotation gradients and circular patterns in EVPA0 are strong evidence for a helical/toroidal magnetic field, and the presence of low intrinsic polarization fractions indicate that the polarized emission and hence the helical/toroidal magnetic field, occur within the innermost jet.

description: This thesis is mainly concerned with a two-state regime switching model with two Ornstein-Uhlenbeck processes and its application to modelling natural gas prices. We start from analyzing Hamilton's (2005) model, a two-state regime switching model in a discrete time setting, and his recursive filtering approach to parameter calibration. Then we discuss the efficiency of models by adding seasonality to the long term mean. We also develop a recursive Bayesian filtering approach and compare it with Hamilton's (2005) filtering approach. This Bayesian calibration approach is applicable to regime switching models in both discrete and continuous time settings.

description: With adaptive optics imaging at Keck observatory, we have discovered a substellar companion to the F6 Pleiades star HD 23514, one of the dustiest main-sequence stars known to date (L_{IR}/L_{*}~2%). This is one of the first brown dwarfs discovered as a companion to a star in the Pleiades. The 0.06 M$_\odot$ late-M secondary has a projected separation of ~360 AU. The scarcity of substellar companions to stellar primaries in the Pleiades combined with the extremely dusty environment make this a unique system to study.

description: We present general methods to exactly calculate mean-first passage quantities on self-similar networks defined recursively. In particular, we calculate the mean first-passage time and the splitting probabilities associated to a source and one or several targets; averaged quantities over a given set of sources (e.g., same-connectivity nodes) are also derived. The exact estimate of such quantities highlights the dependency of first-passage processes with respect to the source-target distance, which has recently revealed to be a key parameter to characterize transport in complex media. We explicitly perform calculations for different classes of recursive networks (finitely ramified fractals, scale-free (trans)fractals, non-fractals, mixtures between fractals and non-fractals, non-decimable hierarchical graphs) of arbitrary size. Our approach unifies and significantly extends the available results in the field.
