Localization Model description of interfacial dynamics of free-standing nanoparticles and thin films, and nanoparticle on supporting interacting substrate
Creators: Mahmud, Gazi A
Publisher: name: University of Alberta Library
Year: 2022

Localization model (LM) relates, without any free parameter, slow dynamics of α-relaxation time (τα) to fast dynamics of Debye-Waller Factor (DWF) or ⟨u2⟩, which is the mean square displacement of particles at a caging time on the order of picoseconds. Moreover, localization model can also predict the diffusion coefficient D when combined with the ‘decoupling’ or Fractional Stokes-Einstein (FSE) relation linking τα to D. Recently, this excellent model has been proven to be useful to predict τα and D of Cu-Zr metallic glass with wide range of compositions from ⟨u2⟩ without any free parameter over a wide range of temperature. Later, the same model is tested for crystalline UO2 under superionic conditions. In the present work, we begin with testing LM for free-standing Cu64Zr36 metallic glass thin films (MGTF) of different thicknesses. We tested LM in overall MGTF, in interfacial region of MGTF where particles have higher mobility, and core or inside of MGTF where particles have less mobility. Free surface of crystalline metallic materials has dynamics similar to the amorphous materials. Hence, in addition to MGTF, we tested this model for interfacial regions of free-standing crystalline Cu thin films with different crystallographic orientation of free surface. After successfully testing LM for overall free-standing Cu64Zr36 MGTFs and their interfaces and cores, we continued the usefulness of this model for the interfacial regions, core, and overall of free-standing Cu64Zr36 metallic glass nanoparticles (MGNP) with different sizes and interfacial regions Cu nanoparticles with different sizes. Finally, we tested this model for interfacial regions, both free interface and Cu-C interface region of Cu NP, of Cu nanoparticles supported on interacting graphene substrate with varying interaction strength between Cu atoms of nanoparticle and C atoms of graphene substrate. We found this model to be very useful to estimate slow dynamics of τα and D to the fast dynamics of DWF for all the cases we studied. In addition to the localization model, we conduct detailed study interfacial dynamics of free standing Cu64Zr36 metallic glass thin films and nanoparticles and crystalline Cu thin films and nanoparticles. Especially, we focused on the interfacial dynamics of Cu NP supported on an interactive supporting graphene substrate and the effects of substrate on the overall dynamics of Cu NP. Moreover, we show that Tammann Temperature (TTA), the minimum temperature for free interface to have enhanced mobility of particles, can be obtained from the intersection of extrapolated ⟨u2⟩ curves of core and interface. We found that the supporting graphene substrate lowers both melting temperature and Tammann temperature of supported Cu NP indicating the higher interfacial activities and, as a result, higher catalytic activities of supported Cu NP.

Brownian motors in micro-scale domain: Enhancement of efficiency by noise

description: We study a noisy drive mechanism for efficiency enhancement of Brownian motors operating on the micro-scale domain. It was proven [J. Spiechowicz et al., J. Stat. Mech. P02044, (2013)] that biased noise $η(t)$ can induce normal and anomalous transport processes similar to those generated by a static force $F$ acting on inertial Brownian particles in a reflection-symmetric periodic structure in presence of symmetric unbiased time-periodic driving. Here, we show that within selected parameter regimes, noise $η(t)$ of the mean value $\langle η(t) \rangle = F$ can be significantly more effective than the deterministic force $F$: the motor can move much faster, its velocity fluctuations are much smaller and the motor efficiency increases several times. These features hold true in both normal and absolute negative mobility regimes. We demonstrate this with detailed simulations by resource to generalized white Poissonian noise. Our theoretical results can be tested and corroborated experimentally by use of a setup that consists of a resistively and capacitively shunted Josephson junction. The suggested strategy to replace $F$ by $η(t)$ may provide a new operating principle in which micro- and nanomotors could be powered by biased noise.

Development of cortical anatomical properties from early childhood to early adulthood

description: Human brain matures in temporal and regional heterogeneity, with some areas matured at early adulthood. In this study, the relationship of cortical structural developments between different cortical sheet regions is systematically analyzed using interregional correlation coefficient and network methods. Specifically, 951 longitudinal T1 brain MR images from 445 healthy subjects with ages from 3 to 20 years old are used. The result shows that the development of cortex reaches a turning point at around 7 years of age: a) the cortical thickness reaches its highest value and also the cortical folding becomes stable at this age; b) both global and local efficiencies of anatomical correlation networks reach the lowest and highest values at this age, respectively; and c) the change of anatomical correlation networks reach the highest level at this age, and the convergence of different anatomical correlation networks starts to decrease from this age. These results might inspire more studies on why there exists a turning point at this age from different viewpoints. For example, is there any change of synaptic pruning, or is it related to the starting of school life? And how can we benefit from this in the real life?

description: In the static analysis of functional programs, pushdown flow analysis and abstract garbage collection push the boundaries of what we can learn about programs statically. This work illuminates and poses solutions to theoretical and practical challenges that stand in the way of combining the power of these techniques. Pushdown flow analysis grants unbounded yet computable polyvariance to the analysis of return-flow in higher-order programs. Abstract garbage collection grants unbounded polyvariance to abstract addresses which become unreachable between invocations of the abstract contexts in which they were created. Pushdown analysis solves the problem of precisely analyzing recursion in higher-order languages; abstract garbage collection is essential in solving the "stickiness" problem. Alone, our benchmarks demonstrate that each method can reduce analysis times and boost precision by orders of magnitude. We combine these methods. The challenge in marrying these techniques is not subtle: computing the reachable control states of a pushdown system relies on limiting access during transition to the top of the stack; abstract garbage collection, on the other hand, needs full access to the entire stack to compute a root set, just as concrete collection does. Conditional pushdown systems were developed for just such a conundrum, but existing methods are ill-suited for the dynamic nature of garbage collection. We show fully precise and approximate solutions to the feasible paths problem for pushdown garbage-collecting control-flow analysis. Experiments reveal synergistic interplay between garbage collection and pushdown techniques, and the fusion demonstrates "better-than-both-worlds" precision.

Adolescent Males' Experiences with Physical Activity
Creators: Jennings, Wendy J
Publisher: name: University of Alberta Library
Year: 2022

Abstract

The benefits of long-term physical activity (PA) lead to a sense of well-being that may be developed and nurtured over the formative years, developing strong, healthy individuals who are positive contributors to society. However, youth participation in PA declines in the adolescent years (ParticipACTION, 2020). Due to lower PA rates among female adolescents (ParticipACTION, 2020), research has focused on female participation. As such, less is known on what influences adolescent males and their participation in PA. Additionally, the sedentary behaviour of adolescent males is increasing in concern and the impact of this behaviour on their health (Michael et al., 2020). To address this gap in understanding regarding the low levels of PA among adolescent males and the strategies to help address it, the purpose of the study was to identify and understand the factors that influence adolescent males’ experiences with PA. Using interpretive phenomenological analysis (IPA) (Alase, 2017) twelve Grade 9 male students from one junior high school participated in semi-structured interviews. Following a socio-ecological framework, the following five levels were used to support the development of the interview guide, frame the data for interpretation, and suggest interventions across the multi-layers: (1) Intrapersonal, (2) Interpersonal, (3) Institutional, (4) Community, and (5) Policy (Sallis & Owen, 2015). Using six phases of thematic analysis (Braun & Clarke, 2006; Braun et al., 2016), themes were created within each of the socio-ecological levels. The findings suggest that adolescent males are influenced by their early experiences that will either hinder further participation, or provide the confidence to continue engaging in PA. Adolescent males identified influential factors such as choosing the activity they enjoy with their friends in a space that allows for competition and growth at their skill level.

The factors that participants’ identified as influencing their engagement in PA are important to broaden the understanding for those who work with adolescent males and to better align programs to enhance their experiences.

description: In 2D topological systems chiral edges may exhibit a spectral change due to the formation of a Bose condensate and partial confinement in the bulk according to the topological symmetry breaking (TSB) mechanism. We analyze in detail what happens in the bulk as well as on the edge for a set of simple chiral fractional quantum Hall systems. TSB corresponds to the spontaneous breaking of a global discrete symmetry and therefore to the appearance of domain walls in the bulk and kinks on the edge. The walls are locally metastable and break if a confined particle-hole pair is created.

description: In previous studies on the capacity of orthogonal frequency division multiple access (OFDMA) systems, it is usually assumed that co-channel interference (CCI) from adjacent cells is a Gaussian-distributed random variable. However, very-little work shows that the Gaussian assumption does not hold true in OFDMA systems. In this paper, the statistical property of CCI in downlink OFDMA systems is studied, and spectral efficiency of downlink OFDMA system is analyzed based on the derived statistical model. First, the probability density function (PDF) of CCI in downlink OFDMA cellular systems is studied with the considerations of path loss, multipath fading and Gaussian-like transmit signals. Moreover, some closed-form expressions of the PDF are obtained for special cases. The derived results show that the PDFs of CCI are with a heavy tail, and significantly deviate from the Gaussian distribution. Then, based on the derived statistical properties of CCI, the downlink spectral efficiency is derived. Numerical and simulation results justify the derived statistical CCI model and spectral efficiency.

description: We present a new Chandra X-ray observation of the off-axis galaxy group merger RXJ0751.3+5012. The hot atmospheres of the two colliding groups appear highly distorted by the merger. The images reveal arc-like cold fronts around each group core, produced by the motion through the ambient medium, and the first detection of a group merger shock front. We detect a clear density and temperature jump associated with a bow shock of Mach number M=1.9+/-0.4 ahead of the northern group. Using galaxy redshifts and the shock velocity of 1100+/-300 km/s, we estimate that the merger axis is only 10deg from the plane of the sky. From the projected group separation of 90 kpc, this corresponds to a time since closest approach of 0.1 Gyr. The northern group hosts a dense, cool core with a ram pressure stripped tail of gas extending 100 kpc. The sheared sides of this tail appear distorted and broadened by Kelvin-Helmholtz instabilities. We use the presence of this substructure to place an upper limit on the magnetic field strength and, for Spitzer-like viscosity, show that the development of these structures is consistent with the critical perturbation length above which instabilities can grow in the intragroup medium. The northern group core also hosts a galaxy pair, UGC4052, with a surrounding IR and near-UV ring 40 kpc in diameter. The ring may have been produced by tidal stripping of a smaller galaxy by UGC4052 or it may be a collisional ring generated by a close encounter between the two large galaxies.

Approximation Algorithms for Clustering with Minimum Sum of Radii, Diameters, and Squared Radii
Creators: Jamshidian, Mahya
Publisher: name: University of Alberta Library
Year: 2022

In this study, we present an improved approximation algorithm for three related problems. In the Minimum Sum of Radii clustering problem (MSR), we aim to select

 k balls in a metric space to cover all points while minimizing the sum of the radii. In the Minimum Sum of Diameters clustering problem (MSD), we are to pick k clusters to cover all the points such that sum of diameters of all the clusters is minimized.

At last, in the Minimum Sum of Squared Radii problem (MSSR), the goal is to choose k balls, similar to MSR. However in MSSR, the goal is to minimize the sum of squares of radii of the balls. We present a 3.389-approximation for MSR and a

6.546-approximation for MSD, improving over respective 3.504 and 7.008 developed by Charkar and Panigrahy (2001). In particular, our guarantee for MSD is better than

twice our guarantee for MSR. In the case of MSSR, the best known approximation guarantee is 4 ·(540)^2 based on the work of Bhowmick, Inamdar, and Varadarajan in

their general analysis of the t-Metric Multicover Problem. With our analysis, we get

a 11.078-approximation algorithm for Minimum Sum of Squared Radii.

description: We study surface subgroups of groups acting simply transitively on vertex sets of certain hyperbolic triangular buildings. The study is motivated by Gromov's famous surface subgroup question: Does every one-ended hyperbolic group contain a subgroup which is isomorphic to the fundamental group of a closed surface of genus at least 2? Here we consider surface subgroups of the 23 torsion free groups acting simply transitively on the vertices of hyperbolic triangular buildings of the smallest non-trivial thickness. These groups gave the first examples of cocompact lattices acting simply transitively on vertices of hyperbolic triangular Kac-Moody buildings that are not right-angled. With the help of computer searches we show, that in most of the cases there are no periodic apartments invariant under the action of a genus two surface. The existence of such an action would imply the existence of a surface subgroup, but it is not known, whether the existence of a surface subgroup implies the existence of a periodic apartment. These groups are the first candidates for groups that have no surface subgroups arising from periodic apartments.

description: Diffusion MR imaging has received increasing attention in the neuroimaging community, as it yields new insights into the microstructural organization of white matter that are not available with conventional MRI techniques. While the technology has enormous potential, diffusion MRI suffers from a unique and complex set of image quality problems, limiting the sensitivity of studies and reducing the accuracy of findings. Furthermore, the acquisition time for diffusion MRI is longer than conventional MRI due to the need for multiple acquisitions to obtain directionally encoded Diffusion Weighted Images (DWI). This leads to increased motion artifacts, reduced signal-to-noise ratio (SNR), and increased proneness to a wide variety of artifacts, including eddy-current and motion artifacts, “venetian blind” artifacts, as well as slice-wise and gradient-wise inconsistencies. Such artifacts mandate stringent Quality Control (QC) schemes in the processing of diffusion MRI data. Most existing QC procedures are conducted in the DWI domain and/or on a voxel level, but our own experiments show that these methods often do not fully detect and eliminate certain types of artifacts, often only visible when investigating groups of DWI's or a derived diffusion model, such as the most-employed diffusion tensor imaging (DTI). Here, we propose a novel regional QC measure in the DTI domain that employs the entropy of the regional distribution of the principal directions (PD). The PD entropy quantifies the scattering and spread of the principal diffusion directions and is invariant to the patient's position in the scanner. High entropy value indicates that the PDs are distributed relatively uniformly, while low entropy value indicates the presence of clusters in the PD distribution. The novel QC measure is intended to complement the existing set of QC procedures by detecting and correcting residual artifacts. Such residual artifacts cause directional bias in the measured PD and here called dominant direction artifacts. Experiments show that our automatic method can reliably detect and potentially correct such artifacts, especially the ones caused by the vibrations of the scanner table during the scan. The results further indicate the usefulness of this method for general quality assessment in DTI studies.

description: We study discrete harmonic analysis associated with ultraspherical orthogonal functions. We establish weighted l^p-boundedness properties of maximal operators and Littlewood-Paley g-functions defined by Poisson and heat semigroups generated by certain difference operator. We also prove weighted l^p-boundedness properties of transplantation operators associated to the system of ultraspherical functions. In order to show our results we previously establish a vector-valued local Calderón-Zygmund theorem in our discrete setting.

description: We are concerned with the Umemura polynomials associated with rational solutions of the third Painlevé equation. We extend Taneda's method, which was developed for the Yablonskii-Vorob'ev polynomials associated with the second Painlevé equation, to give an algebraic proof that the rational functions generated by the nonlinear recurrence relation which determines the Umemura polynomials are indeed polynomials. Our proof is constructive and gives information about the roots of the Umemura polynomials.

description: The "linear dual" of a cocomplete linear category $\mathcal C$ is the category of all cocontinuous linear functors $\mathcal C \to \mathrm{Vect}$. We study the questions of when a cocomplete linear category is reflexive (equivalent to its double dual) or dualizable (the pairing with its dual comes with a corresponding copairing). Our main results are that the category of comodules for a countable-dimensional coassociative coalgebra is always reflexive, but (without any dimension hypothesis) dualizable if and only if it has enough projectives, which rarely happens. Along the way, we prove that the category $\mathrm{Qcoh}(X)$ of quasi-coherent sheaves on a stack $X$ is not dualizable if $X$ is the classifying stack of a semisimple algebraic group in positive characteristic or if $X$ is a scheme containing a closed projective subscheme of positive dimension, but is dualizable if $X$ is the quotient of an affine scheme by a virtually linearly reductive group. Finally we prove tensoriality (a type of Tannakian duality) for affine ind-schemes with countable indexing poset.

description: In Quasimodo il costante sguardo letterario al paesaggio mediterraneo, spesso contrassegnato da tratti edenici, si intreccia sovente con quello delle rovine archeologiche greche e magnogreche in cui il filtro classico agisce mitopoieticamente, proponendo originali riscritture, traduzioni e contestualizzazioni dei miti con un’autentica predilezione per quelli di ambientazione siciliana ispirati particolarmente da Ovidio. Gli itinerari testuali orientati verso l’Antico sono spesso contrassegnati dalla constatazione dello iato esistente tra il passato e la contemporaneità.
description: In Quasimodo’s work, the constant literary gaze at the Mediterranean landscape, often marked by Edenic features, is often intertwined with that of the Greek and Magna Graecia archaeological ruins in which the classical filter acts mythopoetically, proposing original rewritings, translations and contextualisations of the myths with an authentic propensity for those set in Sicily, inspired particularly by Ovid. Textual itineraries oriented towards the Ancient are often marked by the acknowledgement of the existing gap between the past and the contemporary.

description: Many large-scale longitudinal imaging studies have been or are being widely conducted to better understand the progress of neuropsychiatric and neurodegenerative disorders and normal brain development. The goal of this article is to develop a multiscale adaptive generalized estimation equation (MAGEE) method for spatial and adaptive analysis of neuroimaging data from longitudinal studies. MAGEE is applicable to making statistical inference on regression coefficients in both balanced and unbalanced longitudinal designs and even twin and familial studies, whereas standard software platforms have several major limitations in handling these complex studies. Specifically, conventional voxel-based analyses in these software platforms involve Gaussian smoothing imaging data and then independently fitting a statistical model at each voxel. However, the conventional smoothing methods suffer from the lack of spatial adaptivity to the shape and spatial extent of region of interest and the arbitrary choice of smoothing extent, while independently fitting statistical models across voxels does not account for the spatial properties of imaging observations and noise distribution. To address such drawbacks, we adapt a powerful propagation–separation (PS) procedure to sequentially incorporate the neighboring information of each voxel and develop a new novel strategy to solely update a set of parameters of interest, while fixing other nuisance parameters at their initial estimators. Simulation studies and real data analysis show that MAGEE significantly outperforms voxel-based analysis.
