Discovering Disease Associated Gene-Gene Interactions: A Two SNP Interaction Analysis Framework
Creators: name: Antoniades, A.
Publisher: name: Zenodo
Year: 2011

description: Most common diseases have a heritable component that is influenced by mutations on multiple loci, and by interactions between loci and with the environment. However, traditional genetic analysis techniques have focused on single locus effects. This is mostly due to the polynomial increase in computational capacity needed to attempt multi-loci interaction analyses, and the anticipated loss of power due to multiple testing. In this dissertation, a framework for performing a complete two single nucleotide polymorphism (SNP) interaction analysis of high dimensionality genome wide association scans (GWAS) is presented. The implementation of the framework utilizes diverse distributed computational resources to overcome the bottlenecks of each resource, harvesting enough capacity to analyze any of the GWAS in existence today within a reasonable time frame. Algorithmic approaches are proposed to improve the efficiency of the framework and improve its computational performance so that a brute force attack on the problem can be performed. The data is encoded in binary using a lossless algorithm that significantly reduces its size. Computationally efficient data mining measures for the Omnibus and Epistatic interaction effects are proposed and compared to traditional statistical techniques. An algorithm is proposed that optimizes the analyses of multiple response variables within the same GWAS. GenMSA, a multiple sclerosis (MS) dataset, is analyzed using the proposed framework with top results tested for replication using ANZgene, an independent MS, dataset. Some of the top results replicated, implicating SNPs in a region of known association to MS providing evidence to the validity of the proposed framework. Top results are further examined through a proposed approach that enables drilling into these results and studying correlation coefficient between each of the genotype combinations of the SNP and the signal level to each of the main and epistatic effects.

Interacting Markov chain Monte Carlo methods for solving nonlinear measure-valued equations
Creators: name: Del Moral, Pierre

Publisher: name: arXiv
Year: 2010
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We present a new class of interacting Markov chain Monte Carlo algorithms for solving numerically discrete-time measure-valued equations. The associated stochastic processes belong to the class of self-interacting Markov chains. In contrast to traditional Markov chains, their time evolutions depend on the occupation measure of their past values. This general methodology allows us to provide a natural way to sample from a sequence of target probability measures of increasing complexity. We develop an original theoretical analysis to analyze the behavior of these iterative algorithms which relies on measure-valued processes and semigroup techniques. We establish a variety of convergence results including exponential estimates and a uniform convergence theorem with respect to the number of target distributions. We also illustrate these algorithms in the context of Feynman-Kac distribution flows.

description: Utilizing a newly compiled data set, this article demonstrates that some election pledges made by the transnational Europarties are included among the European Commission priorities issued during the pre-legislative stage. The data set consists of 597 promises made by four transnational Europarties during the 2004 and 2009 European Parliament (EP) elections and of 698 subsequent Commission legislative intentions. Focusing on the time periods during the Barroso presidencies, the article’s findings suggest that (1) decision-making rules in the EP help us understand which transnational pledges are included in Commission priorities and (2) promises by two Europarties, such as the European People’s Party and the European Liberal and Democrat Party, are more likely to be considered by the Commission than those of other Europarties. Our results speak to scholarly debates on the place of the Europarties in the European Union inter-institutional relations and more broadly on the democratic legitimacy of the Union.

description: The trimuon signature appears in leptonic decays of charginos and neutralinos and potentially has only a small SM background in comparison with other SUSY searches. This allows to perform SUSY searches without requiring cuts on missing transverse energy or the number of jets and their energies, which are prone to large uncertainties during the first year of operation. This signature also allows for a data driven efficiency and background estimation from SM signatures with fake and prompt muons.

description: We study the relationship between the gas column density (Sigma_HI) and the star formation rate surface density (Sigma_SFR) for a sample of extremely small (M_B ~ -13, Delta V_50 ~ 30 km/s) dwarf irregular galaxies. We find a clear stochasticity in the relation between the gas column density and star formation. All gas with Sigma_HI >~ 10 M_sun/pc^2 has some ongoing star formation, but the fraction of gas with ongoing star formation decreases as the gas column density decreases, and falls to about 50% at Sigma_HI ~ 3 M_sun/pc^2. Further, even for the most dense gas, the star formation efficiency is at least a factor of ~ 2 smaller than typical of star forming regions in spirals. We also find that the ratio of H-alpha emission to FUV emission increases with increasing gas column density. This is unlikely to be due to increasing dust extinction because the required dust to gas ratios are too high. We suggest instead that this correlation arises because massive (i.e. H-alpha producing) stars are formed preferentially in regions with high gas density.

description: We address the issue of setting up generic non-Gaussian initial conditions for N-body simulations. We consider inflationary-motivated primordial non-Gaussianity where the perturbations in the Bardeen potential are given by a dominant Gaussian part plus a non-Gaussian part specified by its bispectrum. The approach we explore here is suitable for any bispectrum, i.e. it does not have to be of the so-called separable or factorizable form. The procedure of generating a non-Gaussian field with a given bispectrum (and a given power spectrum for the Gaussian component) is not univocal, and care must be taken so that higher-order corrections do not leave a too large signature on the power spectrum. This is so far a limiting factor of our approach. We then run N-body simulations for the most popular inflationary-motivated non-Gaussian shapes. The halo mass function and the non-linear power spectrum agree with theoretical analytical approximations proposed in the literature, even if they were so far developed and tested only for a particular shape (the local one). We plan to make the simulations outputs available to the community via the non-Gaussian simulations comparison project web site http://icc.ub.edu/~liciaverde/NGSCP.html.

description: Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the lubricant-substrate interaction) confined between two solids. At low driving velocities the system demonstrates stick-slip motion. The lubricant may or may not be melted during sliding, thus exhibiting either the "liquid sliding" (LS) or the "layer over layer sliding" (LoLS) regimes. The LoLS regime mainly operates at low sliding velocities. We investigate the dependence of friction properties on the misfit angle between the sliding surfaces and calculate the distribution of static frictional thresholds for a contact of polycrystalline surfaces.

description: We compare calcium ion signaling ($\mathrm {Ca}^{2+}$) between two exposures; the data are present as movies, or, more prosaically, time series of images. This paper describes novel uses of singular value decompositions (SVD) and weighted versions of them (WSVD) to extract the signals from such movies, in a way that is semi-automatic and tuned closely to the actual data and their many complexities. These complexities include the following. First, the images themselves are of no interest: all interest focuses on the behavior of individual cells across time, and thus, the cells need to be segmented in an automated manner. Second, the cells themselves have 100$+$ pixels, so that they form 100$+$ curves measured over time, so that data compression is required to extract the features of these curves. Third, some of the pixels in some of the cells are subject to image saturation due to bit depth limits, and this saturation needs to be accounted for if one is to normalize the images in a reasonably unbiased manner. Finally, the $\mathrm {Ca}^{2+}$ signals have oscillations or waves that vary with time and these signals need to be extracted. Thus, our aim is to show how to use multiple weighted and standard singular value decompositions to detect, extract and clarify the $\mathrm {Ca}^{2+}$ signals. Our signal extraction methods then lead to simple although finely focused statistical methods to compare $\mathrm {Ca}^{2+}$ signals across experimental conditions.

title: Living standards within households : learning from non-monetary indicators
Creators: name: Cantillon, Sara
Publisher: name: University of Kent
Year: 2021

description: This dissertation focuses on the distribution of resources within Irish households and the implications of that distribution for the living standards of different household members. Inmost research on living standards, income inequality and poverty, the assumption is made that individuals living in the same household have the same standard of living. If however, different individuals within households actually experience different levels of well-being, this could have major implications for our understanding of poverty. In particular, conventional practice could lead to the extent and nature of gender differences in the experience of poverty being understated, to poverty for some children being obscured, and to the capacity of policy to improve living standards being seriously impaired. Non-monetary indicators of living standards and deprivation are increasingly being used in measuring household poverty. This study demonstrates their use in exploring differences in living standards within households. The aim of the present study was to develop a set of indicators suitable for the investigation of differences in living standards within the household - both differences between adults in a given household, and between adults and children - and to apply these indicators empirically to Ireland. This involved first designing a module of survey questions and refining them through focus group discussions with women experiencing poverty and social exclusion. The resulting set of questions was then included in the 1999 round of the Living in Ireland Survey. Research has then been carried out on the responses to this innovative set of specially-designed questions, focused on bringing out the scale and nature of differences within the household and teasing out the influences on the intra-household distribution of resources. In particular it looked at the role a woman's independent income might play and also at the impact of the presence of another adult at the interview. The results are revealing both in the specific Irish context and more broadly, from a methodological and substantive point of view.
Gaussian Regularized Sliced Inverse Regression

description: Sliced Inverse Regression (SIR) is an effective method for dimension reduction in high-dimensional regression problems. The original method, however, requires the inversion of the predictors covariance matrix. In case of collinearity between these predictors or small sample sizes compared to the dimension, the inversion is not possible and a regularization technique has to be used. Our approach is based on a Fisher Lecture given by R.D. Cook where it is shown that SIR axes can be interpreted as solutions of an inverse regression problem. In this paper, a Gaussian prior distribution is introduced on the unknown parameters of the inverse regression problem in order to regularize their estimation. We show that some existing SIR regularizations can enter our framework, which permits a global understanding of these methods. Three new priors are proposed leading to new regularizations of the SIR method. A comparison on simulated data is provided.

Operational modal analysis, model updating and response prediction bridge under the 2014 Napa Earthquake
Creators: name: Alcazar Pastrana, Omar
Publisher: name: University of British Columbia
Year: 2016

description: Bridges constitute a critical and important part of the infrastructure of many cities’ transportation network. They are expensive to build and maintain, and the consequences of a sudden failure are very severe. Therefore, bridges are expected to have a high degree of reliability, which means that they have to perform above a life safety criterion under earthquake excitations. In a continuous effort to improve design guidelines, it is imperative to understand the behavior of existing bridges that are subjected to severe shaking. For this reason, continuous monitoring of bridges has become essential: not only to help determine if a bridge has been damaged but also to understand their response to strong earthquake motions. The work reported here includes an in-depth analysis of the behavior of the Vallejo- Hwy 37 Napa River Bridge during the 2014 California, Napa earthquake (M 6.0). The bridge located in Vallejo California connects Sears Point Road and Mare Island to Vallejo. It was built in 1967. The bridge was instrumented with 12 accelerometers on the superstructure and 3 accelerometers at a free-field site. An analysis of the recorded data of the accelerometers on the superstructure was carried out to determine the maximum displacement at mid-span, and to get the fundamental frequencies of the bridge during the excitation. A finite element (FE) model was developed based on the as-built drawings and model updaitng was perform. Finally, the updated model was used with the recorded ground motion of the 2014 Napa Earthquake to perform a time history analysis. The results were compared to the recorded data of the sensors located on the bridge. The peak displacement at mid-span in the longitudinal and transverse directions of the FE had a good match to the recorded peak displacement. It can be concluded that the updated FE model can capture the peak displacement at the bridge mid-span. It also shows that having a strong motion network can help engineers to better understand the behavior of structures under earthquake loading, by looking at the recorded data and identifying peak values of acceleration, velocity and displacement.

description: Background: Many advanced practice nursing programs incorporate interprofessional collaboration into the curriculum. Few combine intraprofessional collaboration between nurse practitioner (NP) students of different population foci. Telephone triage is a skill that is rarely covered in NP education. Description: We describe a simulation program in which family nurse practitioner (FNP) students collaborate with psychiatric mental health nurse practitioner (PMHNP) students in a drug-seeking telephone triage scenario. The patient was portrayed by an improvisational actor. Forty-seven FNP students and 14 PMHNP students participated in the scenario. Outcome: Students reported that the telephone triage scenario was useful and that they would be more likely to both collaborate with and refer patients to NPs from the other specialties. Conclusions: With some modifications, combining FNP and PMHNP students in a telephone triage simulation scenario is beneficial to both groups of students.
Land use regression modelling of NO₂, NO, PM₂.₅ and black carbon in Hong Kong
Creators: name: Lee, Martha
Publisher: name: University of British Columbia
Year: 2016

description: Land use regression (LUR) modelling is a common method for estimating pollutant concentrations. This project created two-dimensional LUR models for nitrogen dioxide (NO₂), nitric oxide (NO), fine particulate matter (PM₂.₅), and black carbon (BC) for Hong Kong, a prototypical high-density high-rise city. Two sampling campaigns (April-May and November-January) were carried out in Hong Kong. Measurements of NO₂ and NO (2-3-week averaged) and PM₂.₅ and BC (24-hour averaged) were adjusted for instrument bias and temporal variation, and offered to multiple linear regression models along with 365 potential geospatial predictor variables. Variables were created from a number of geospatial metrics including land use and traffic variables (road length, average annual daily traffic [AADT], traffic loading [AADT * road length]). Measurement averaged across both campaigns were: a) NO₂ (M = 106 μg/m³, SD = 38.5, N = 95), b) NO (M = 147 μg/m³, SD = 88.9, N = 40), c) PM₂.₅ (M = 35 μg/m³, SD = 6.3, N = 64), and BC (M = 10.6 μg/m³, SD = 5.3, N = 76). Thirty-six LUR models were created (4 pollutants * 3 combined and separate sampling campaigns * 3 traffic variable type). The annual (combined values from both campaigns) road length models were selected as preferred models based on data reliability and overall model fit. Road length, car park density, and land use types were commonly selected predictors in the final preferred models. The preferred models had the following parameters: a) NO₂ (R² = 0.46, RMSE = 28 μg/m³) b) NO (R² = 0.50, RMSE = 62 μg/m³), c) PM₂.₅ (R² = 0.59; RMSE = 4 μg/m³), and d) BC (R² = 0.50, RMSE = 4 μg/m³). NO₂ predictions were strongly influenced by traffic and higher around Kowloon and northern Hong Kong Island. PM₂.₅ predictions had a strong northwest (high) to southeast (low) gradient. BC had a similar gradient and high predictions around the port. This matched with existing literature of spatial variation and sources in Hong Kong. Spatial patterns varied by pollutant. The success of this modelling suggests LUR modelling is appropriate in high-density high-rise cities.

description: In this paper, auto-associative models are proposed as candidates to the generalization of Principal Component Analysis. We show that these models are dedicated to the approximation of the dataset by a manifold. Here, the word "manifold" refers to the topology properties of the structure. The approximating manifold is built by a projection pursuit algorithm. At each step of the algorithm, the dimension of the manifold is incremented. Some theoretical properties are provided. In particular, we can show that, at each step of the algorithm, the mean residuals norm is not increased. Moreover, it is also established that the algorithm converges in a finite number of steps. Some particular auto-associative models are exhibited and compared to the classical PCA and some neural networks models. Implementation aspects are discussed. We show that, in numerous cases, no optimization procedure is required. Some illustrations on simulated and real data are presented.

description: Controlling the depolarization of light is a long-standing open problem. In recent years, many demonstrations have used the polarization of single photons to encode quantum information. The depolarization of these photons is equivalent to the decoherence of the quantum information they encode. We present schemes for building various depolarizing channels with controlled properties using birefringent crystals. Three such schemes are demonstrated and their effects on single photons are shown by quantum process tomography to be in good agreement with a theoretical model.

This same field of 40' by 40' is covered in all four IRAC bands as well as the longer wavelength MIPS bands (70 and 160um). The r' imaging covers 0.8 deg2 down to 25.5 magnitudes, and overlaps with most of the MIPS field of view. The J, H, Ks images cover the cluster core and roughly half of the filament galaxies, which extend towards the neighboring cluster, Abell 1770. This first, in a series of papers on Abell 1763, discusses the data reduction methods and source extraction techniques used for each dataset. We present catalogs of infrared (IR) sources (with 24 and/or 70um emission) and their corresponding emission in the optical (u', g', r', i', z'), and Near- to Far-IR (J, H, Ks, IRAC, and MIPS 160um). We provide the catalogs and reduced images to the community through the NASA/IPAC Infrared Science Archive (IRSA).

description: Background: Transitioning from a Master of Science degree to a Doctorate of Nursing Practice degree in a Family Nurse Practitioner program presents a challenge in course sequencing. If DNP coursework is placed after concurrent clinical and didactic courses, students will encounter situations in clinical that they have not studied in the didactic arena (increasing preceptor burden) and complete their clinicals a year before graduation. We adopted a front-loaded course sequence, placing didactic management courses before the start of clinical courses. However, students would now be exposed to didactic management content a year before beginning clinical. Methods: To enhance readiness for clinicals, we implemented a program, “Conquering Clinical,” which included a full day of simulation that reviewed four scenarios frequently encountered in primary care. Results: The students reported feeling both more confident and more competent in conducting a primary care encounter. Conclusion: A preclinical preparation program is beneficial to both students and preceptors.

description: We have measured the oscillator strength and quantum efficiency of excitons confined in large InGaAs quantum dots by recording the spontaneous emission decay rate while systematically varying the distance between the quantum dots and a semiconductor-air interface. The size of the quantum dots is measured by in-plane transmission electron microscopy and we find average in-plane diameters of 40 nm. We have calculated the oscillator strength of excitons of that size and predict a very large oscillator strength due to Coulomb effects. This is in stark contrast to the measured oscillator strength, which turns out to be much below the upper limit imposed by the strong confinement model. We attribute these findings to exciton localization in local potential minima arising from alloy intermixing inside the quantum dots.

title: Tree structures in the geometric representation theory of quivers
Creators: name: Weist, Thorsten
Publisher: name: Bergische Universität Wuppertal

description: One of the major goals in the representation theory of quivers is the classification of isomorphism classes of representations of arbitrary quivers and the homomorphism spaces between them. Whence the classification problem is solved for representations of quivers of Dynkin type and those of extended Dynkin type, it is regarded as very hard for the remaining wild quivers. One of the main aims of this habilitation is to make a contribution to geometric representation theory with focus on wild quivers. Thereby, tree structures happen to play an important role. We concentrate on three aspects. The first one contributes to the mentioned classification problem in such a way that we introduce methods which can be used to construct isomorphism classes of indecomposable representations which can be described by as many parameters as predicted by Kac's Theorem. Often tree modules serve as a skeleton in this construction and the investigations raise hope that, at least for a certain class of roots, further considerations can lead to a normal form for indecomposable quiver representations. Geometric considerations build the bridge to the second, cohomological, aspect. Maybe the main knowledge gained in this theory throughout the last years is that the Euler characteristic of moduli spaces of stable quiver representations can be obtained in a purely combinatorial way when counting certain trees. But this is not the end of the story as there is an equivalent formula in the theory of Gromov-Witten invariants counting rational curves on weighted projective planes. In a sense, it turns out that in the theory of Gromov-Witten invariants certain tropical curves, whose underlying graphs are also trees, play the role of torus fixed points of moduli spaces. The third aspect is on the investigation of quiver Grassmannians attached to representations of extended Dynkin quivers of type D. We show that every quiver Grassmannian admits a cell decomposition into affine spaces. As we can associate a tree with each cell, the Euler characteristic is already given by its number. This can be used to obtain an explicit description of the generating functions of the Euler characteristics. These generating functions are then again important in the theory of cluster algebras as they can be used to determine the corresponding cluster variables.

description: The spin Seebeck effect (SSE) is known as the generation of 'spin voltage' in a magnet as a result of a temperature gradient. Spin voltage stands for the potential for spins, which drives a spin current. The SSE is of crucial importance in spintronics and energy-conversion technology, since it enables simple and versatile generation of spin currents from heat. The SSE has been observed in a variety of materials ranging from magnetic metals and semiconductors to magnetic insulators. However, the mechanism, the long-range nature, of the SSE in metals is still to be clarified. Here we found that, using a Ni81Fe19/Pt bilayer wire on an insulating sapphire plate, the long-range spin voltage induced by the SSE in magnetic metals is due to phonons. Under a temperature gradient in the sapphire, surprisingly, the voltage generated in the Pt layer is shown to reflect the wire position, although the wire is isolated both electrically and magnetically. This non-local voltage is direct evidence that the SSE is attributed to the coupling of spins and phonons. We demonstrate this coupling by directly injecting sound waves, which realizes the acoustic spin pumping. Our finding opens the door to "acoustic spintronics" in which phonons are exploited for constructing spin-based devices.

description: Tutte’s embedding theorem states that every 3-connected graph without a K5- or K3,3-minor (i.e., a planar graph) is embedded in the plane if the outer face is in convex position and the interior vertices are convex combinations of their neighbors. We show that this result extends to simply connected tetrahedral meshes in a natural way: for the tetrahedral mesh to be embedded if the outer polyhedron is in convex position and the interior vertices are convex combination of their neighbors it is sufficient (but not necessary) that the graph of the tetrahedral mesh contains no K6 and no K3,3,1, and all triangles incident on three boundary vertices are boundary triangles.
Spitzer observations of Abell 1763 - II: Constraining the nature of activity in the cluster-feeding filament with VLA and XMM-Newton data

description: The Abell 1763 superstructure at z=0.23 contains the first galaxy filament to be directly detected using mid-infrared observations. Our previous work has shown that the frequency of starbursting galaxies, as characterized by 24μm emission is much higher within the filament than at either the center of the rich galaxy cluster, or the field surrounding the system. New VLA and XMM-Newton data are presented here. We use the radio and X-ray data to examine the fraction and location of active galaxies, both active galactic nuclei (AGN) and starbursts. The radio far-infrared correlation, X-ray point source location, IRAC colors, and quasar positions are all used to gain an understanding of the presence of dominant AGN. We find very few MIPS-selected galaxies that are clearly dominated by AGN activity. Most radio selected members within the filament are starbursts. Within the supercluster, 3 of 8 spectroscopic members detected both in the radio and in the mid-infrared are radio-bright AGN. They are found at or near the core of Abell 1763. The five starbursts are located further along the filament. We calculate the physical properties of the known wide angle tail (WAT) source which is the brightest cluster galaxy (BCG) of Abell 1763. A second double lobe source is found along the filament well outside of the virial radius of either cluster. The velocity offset of the WAT from the X-ray centroid, and the bend of the WAT in the intracluster medium (ICM) are both consistent with ram pressure stripping, indicative of streaming motions along the direction of the filament. We consider this as further evidence of the cluster-feeding nature of the galaxy filament.

description: The key to the transformation of resource-based rural economy lies in the land use transition, which has important theoretical and practical significance for the reconstruction of rural values and the promotion of rural revitalization. Taking Taolingou Village in Yangquan City, Shanxi Province as an example, on the basis of expounding the concept and connotation of land use transition, this paper analyzes the evolution trend of resource-based rural land use transition, explores the driving force of resource-based rural land use transition and clearly puts forward the measures to strengthen the transformation of resource-based rural land use in the context of rural revitalization. The analysis shows that the land use of Taolingou Village is transforming towards the trend of sustainability, putting people first and multi-function, which is consistent with the strategic goal of rural revitalization; The driving force of land use transition in Taolingou Village includes four aspects, namely, industrial structure, economic factors, development policy and contradiction between human and land; Adjusting and optimizing the industrial structure, protecting the ecological environment, perfecting relevant policies and regulations, and controlling the overall population are the effective measures for Taolingou Village to realize the land use transition. This case study is expected to provide a useful reference for the land use transition in other resource-based rural areas.

description: In this Letter, we investigate the stability of the statistical equilibrium of spherically symmetric collisionless self-gravitating systems. By calculating the second variation of the entropy, we find that perturbations of the relevant physical quantities should be classified as long- and short-range perturbations, which correspond to the long- and short-range relaxation mechanisms, respectively. We show that the statistical equilibrium states of self-gravitating systems are neither maximum nor minimum, but complex saddle-point entropy states, and hence differ greatly from the case of ideal gas. Violent relaxation should be divided into two phases. The first phase is the entropy-production phase, while the second phase is the entropy-decreasing phase. We speculate that the second-phase violent relaxation may just be the long-wave Landau damping, which would work together with short-range relaxations to keep the system equilibrated around the saddle-point entropy states.
