description: The collision and thus separation of two symmetrical, laminar, steady planar wall jets of a Newtonian fluid with uniform properties at arbitrarily large Reynolds number (Re) poses a long-standing problem in boundary layer theory and beyond. In its to date most celebrated form, it was posed first by Stewartson (Boundary Layer Research: IUTAM Symposium Freiburg/Br., 1958) as the equatorial collision of the meridional flow past a sphere (body of revolution, generally) due to its rotation in an unbounded, otherwise quiescent environment. The asymptotic flow structure put forward originally consists essentially of an Euler region governing the separation of the viscous sublayer underneath. Even though indicated intuitively back then, this structure can be shown rigorously as inconsistent with the branching of the incident wall jet, which is inevitably controlled by viscous-inviscid interaction of double-deck type. This mechanism was proposed to be at play already by Smith & Duck (Q. J. Mech. Appl. Math., 30 (2), 1977). In turn, they predicted much larger recirculation eddies and the absence of the Euler region. Despite its rationally founded preference, this self-consistent structure was never detected in the numerical solutions of the full Navier-Stokes equations (NSE), which raised a quite recent controversy. We aim at resolving this by demonstrating that the flow detaches in an eddy-free manner for large but finite values of Re, whereas it is either intrinsically unsteady or unstable for even larger ones and presumably undergoes quickly laminar-turbulent transition. To this end, we obtained accurate transient numerical solutions of the NSE and performed an asymptotic analysis, amongst others devoted to the stability of the structure by Smith & Duck. These preliminary findings also tie in with well-understood analogous situations in the theory of external high-Re flows. Remarkably, the recirculation eddies indeed appear for a fraction of time, which points to a too short transient period in the recent numerical studies and might explain their partial favouritism of Stewartson's structure.

description: Civic participation serves as a cornerstone of democratic governance, encompassing diverse activities aimed at addressing communal challenges and influencing governmental actions. This study delves into the nexus between social media usage among youth and their offline engagement in civic activities within Tanzania during non-election periods. Drawing on insights from Barrett and Brunton-Smith (2014), Verba et al. (1978), Nah and Yamamoto (2017), and Gil de Zuniga et al. (2016), the research underscores the transformative potential of civic participation in nurturing collective identity, mutual respect, and social responsibility—foundational elements of a vibrant civil society. By exploring the role of social media platforms as facilitators of youth civic engagement, the study illuminates the dynamics shaping contemporary civic activism and its implications for democratic governance. Through empirical analysis and theoretical frameworks, the research elucidates the mechanisms through which social media usage influences offline civic participation among Tanzanian youth, offering valuable insights into the evolving landscape of civic engagement in non-election contexts.

description: We address the cross effects between mechanical strains and magnetic fields on the plastic response of magnetoelastic amorphous solids. It is well known that plasticity in non-magnetic amorphous solids under external strain $γ$ is dominated by the co-dimension 1 saddle-node bifurcation in which an eigenvalue of the Hessian matrix vanishes at $γ_P$ like $\sqrt{γ_P-γ}$. This square-root singularity determines much of the statistical physics of elasto-plasticity, and in particular that of the stress-strain curves under athermal-quasistatic conditions. In this Letter we discuss the much richer physics that can be expected in magnetic amorphous solids. Firstly, magnetic amorphous solids exhibit co-dimension 2 plastic instabilities, when an external strain and an external magnetic field are applied simultaneously. Secondly, the phase diagrams promise a rich array of new effects that have been barely studied; this opens up a novel and extremely rich research program for magnetoplastic materials.

description: We performed univariate and multivariate discriminant analysis of FDG-PET scans to evaluate their ability to identify Alzheimer's disease (AD). FDG-PET scans came from two sources: 17 AD patients and 33 healthy elderly controls were scanned at the University of Michigan; 102 early AD patients and 20 healthy elderly controls were scanned at the Technical University of Munich, Germany. We selected a derivation sample of 20 AD patients and 20 healthy controls matched on age with the remainder divided into 5 replication samples. The sensitivity and specificity of diagnostic AD-markers and threshold criteria from the derivation sample were determined in the replication samples. Although both univariate and multivariate analyses produced markers with high classification accuracy in the derivation sample, the multivariate marker's diagnostic performance in the replication samples was superior. Further, supplementary analysis showed its performance to be unaffected by the loss of key regions. Multivariate measures of AD utilize the covariance structure of imaging data and provide complementary, clinically relevant information that may be superior to univariate measures.

description: We have fabricated c-axis point contact junctions between high-quality LiFeAs single crystals and Pb or Au tips in order to study the nature of the superconducting order parameter of LiFeAs, one of the few stoichiometric iron-based superconductors. The observation of the Josephson current in c-axis junctions with a conventional s-wave superconductor as the counterelectrode indicates that the pairing symmetry in LiFeAs is not pure d-wave or pure spin-triplet p-wave. A superconducting gap is clearly observed in point contact Andreev reflection measurements performed on both Pb/LiFeAs and Au/LiFeAs junctions. The conductance spectra can be well described by the Blonder-Tinkham-Klapwijk model with a lifetime broadening term, resulting in a gap value of \approx 1.6 meV (2Δ/kBTC \approx 2.2).

description: Background: Positron emission tomography (PET) is a molecular imaging technology that enables in vivo quantification of metabolic activity or receptor density, among other applications. Examples of applications of PET imaging in neuroscience include studies of neuroreceptor/neurotransmitter levels in neuropsychiatric diseases (e.g., measuring receptor expression in schizophrenia) and of misfolded protein levels in neurodegenerative diseases (e.g., beta amyloid and tau deposits in Alzheimer’s disease). Assessment of a PET tracer’s test-retest properties is an important component of tracer validation, and it is usually carried out using data from a small number of subjects.

Results: Here, we investigate advantages and limitations of test-retest metrics that are commonly used for PET brain imaging, including percent test-retest difference and intraclass correlation coefficient (ICC). In addition, we show how random effects analysis of variance, which forms the basis for ICC, can be used to derive additional test-retest metrics, which are generally not reported in the PET brain imaging test-retest literature, such as within-subject coefficient of variation and repeatability coefficient. We reevaluate data from five published clinical PET imaging test-retest studies to illustrate the relative merits and utility of the various test-retest metrics. We provide recommendations on evaluation of test-retest in brain PET imaging and show how the random effects ANOVA based metrics can be used to supplement the commonly used metrics such as percent test-retest.

Conclusions: Random effects ANOVA is a useful model for PET brain imaging test-retest studies. The metrics that ensue from this model are recommended to be reported along with the percent test-retest metric as they capture various sources of variability in the PET test-retest experiments in a succinct way.

description: INTRODUCTION: The Dependence Scale (DS) was designed to measure dependence on others among patients with Alzheimer's disease (AD). The objectives of this research were primarily to strengthen the psychometric evidence for the use of the DS in AD studies. METHODS: Patients with mild to moderately severe AD were examined in 3 study databases. Within each data set, internal consistency, validity, and responsiveness were examined, and structural equation models were fit. RESULTS: The DS has strong psychometric properties. The DS scores differed significantly across known groups and demonstrated moderate to strong correlations with measures hypothesized to be related to dependence (|r| >/= .31). Structural equation modeling supported the validity of the DS concept. An anchor-based DS responder definition to interpret a treatment benefit over time was identified. DISCUSSION: The DS is a reliable, valid, and interpretable measure of dependence associated with AD and is shown to be related to--but provides information distinct from--cognition, functioning, and behavior.
Mechanism of deposition and functional characterization of the histone variant H2A.Z in Saccharomyces cerevisiae
Creators: name: Wang, Yijun
Publisher: name: University of British Columbia
Year: 2012

description: Eukaryotic DNA is packaged into the cell nucleus together with histones and other proteins as a complex called chromatin. The dynamic structure of chromatin is crucial for genome regulation and is created by a variety of mechanisms including post-translational modifications, ATP-dependent remodeling, and replacement by histone variants. My dissertation investigates the structure and function of central players in the biology of histone H2A.Z, an important and yet enigmatic variant of H2A. Unlike H2A, which is deposited randomly in the genome, H2A.Z is deposited to specific locations by its dedicated ATP-dependent complex SWR1-C. One subunit that belongs to SWR1-C is Yaf9, which contains the conserved yet largely unexplored YEATS domain. Here, I established the conservation of YEATS domain function from yeast to human. I determined that the three-dimensional structure of the Yaf9 YEATS domain from Saccharyomyces cerevisiae was highly similar to that of the histone chaperone Asf1, a similarity that extended to an ability of Yaf9 to bind histones H3 and H4 in vitro. In addition, I found that the Yaf9 YEATS domain was required for H2A.Z deposition at specific promoters. Focusing on the histone variant itself, I explored the precise features required for H2A.Z to function and specify its unique identity from canonical H2A. I specifically studied the C-terminal docking domain, an area of significant structural and sequence variation between H2A.Z and H2A. I determined that the last 20 amino acids of H2A.Z was required for its chromatin-anchoring ability and functions in vivo, even though it was not required for SWR1-C interaction. Furthermore, I demonstrated that M6, a region in the docking domain that diverged considerably from H2A, was required but not sufficient for H2A.Z–specific functions, including binding to SWR1-C. Finally, I found that the M6 region was both required and sufficient for binding to the H2A.Z-specific histone chaperone Chz1. In summary, my dissertation contributes to our understanding of the structure and function of the Yaf9 YEATS domain in the context of H2A.Z deposition, as well as the distinct regions of the H2A.Z C-terminal docking domain that are either required for its function or confer its uniqueness.

description: Ultracold polar molecules in multilayered systems have been experimentally realized very recently. While experiments study these systems almost exclusively through their chemical reactivity, the outlook for creating and manipulating exotic few- and many-body physics in dipolar systems is fascinating. Here we concentrate on few-body states in a multilayered setup. We exploit the geometry of the interlayer potential to calculate the two- and three-body chains with one molecule in each layer. The focus is on dipoles that are aligned at some angle with respect to the layer planes by means of an external eletric field. The binding energy and the spatial structure of the bound states are studied in several different ways using analytical approaches. The results are compared to stochastic variational calculations and very good agreement is found. We conclude that approximations based on harmonic oscillator potentials are accurate even for tilted dipoles when the geometry of the potential landscape is taken into account.

description: The gas-liquid phase transition of the three-dimensional Lennard-Jones particles system is studied by molecular dynamics simulations. The gas and liquid densities in the coexisting state are determined with high accuracy. The critical point is determined by the block density analysis of the Binder parameter with the aid of the law of rectilinear diameter. From the critical behavior of the gas-liquid coexsisting density, the critical exponent of the order parameter is estimated to be $β= 0.3285(7)$. Surface tension is estimated from interface broadening behavior due to capillary waves. From the critical behavior of the surface tension, the critical exponent of the correlation length is estimated to be $ν= 0.63 (4)$. The obtained values of $β$ and $ν$ are consistent with those of the Ising universality class.

description: As clinical and cognitive neurosciences mature, the need for sophisticated neuroimaging analysis becomes more apparent. Multivariate analysis techniques have recently received increasing attention because they have attractive features that cannot be easily realized by the more commonly used univariate, voxel-wise, techniques. Multivariate approaches evaluate correlation/covariance of activation across brain regions, rather than proceeding on a voxel-by-voxel basis. Thus, their results can be more easily interpreted as a signature of neural networks. Univariate approaches, in contrast, cannot directly address functional connectivity in the brain. Apart from this conceptual difference, the covariance approach can also result in greater statistical power when compared with univariate techniques, which are forced to employ very stringent, and often overly conservative, corrections for voxel-wise multiple comparisons. Multivariate techniques also lend themselves much better to prospective application of results from the analysis of one dataset to entirely new datasets. We provide two examples that illustrate different uses of multivariate techniques in cognitive and clinical neuroscience. We hope this contribution helps facilitate wider dissemination of these techniques in the research community

description: Global Citizenship Education (GCE) has received increasing attention as a means of supporting children and young people in developing their knowledge and understanding of multiple global issues (Bourn, 2015; Fricke & Gathercole, 2015). Despite this increasing prominence, it is apparent that GCE remains a highly contested notion (Marshall, 2005; Hartung, 2017; Jooste & Heleta, 2017). The report draws on an analysis of nine Global Citizenship Education teacher education programmes across four EU countries: Austria, Czech Republic, Ireland and Italy. The methodology adopted is a multiple-site case study design (Yin, 2014), using ethnography as main method. The research employed a qualitative framework, seeking a description of practices and meaning making to behavioural patterns. Within each country, the research focused on an analysis of two typologies of settings: a) a training course for in-service primary school teachers organized by the project partner in the framework of the project, b) a training course organized by a different organization on themes related to Global Citizenship Education. The selection of the second setting was based on extreme case sampling. This setting was selected for being as different as possible from the initial one, in terms of approach, goals, teachers’ trainers and organization (but on the same or related theme). The theoretical assumption behind this choice is that being organized by a different institution the ideas behind course implementation are more likely to be different.
Based on this the report argues that the teacher education programmes examined present an argument as to how teacher education programmes at the focus of this research present a transformational approach to GCE, where the concepts of critical thinking and self-reflection are perceived as the foundations towards action for a more just and sustainable world. This conception echoes aspects of Freirean pedagogy, itself an important GCE theoretical framework (Scheunpflug & Asbrand, 2006). However, less evident was the ‘critical’ approach to GCE, illustrated in the work of Andreotti (2006).

description: A nano-scale metallic grain in which the single-particle dynamics are chaotic is described by the so-called universal Hamiltonian. This Hamiltonian includes a superconducting pairing term and a ferromagnetic exchange term that compete with each other: pairing correlations favor minimal ground-state spin, while the exchange interaction favors maximal spin polarization. Of particular interest is the fluctuation-dominated regime where the bulk pairing gap is comparable to or smaller than the single-particle mean level spacing and the Bardeen-Cooper-Schrieffer theory of superconductivity breaks down. Superconductivity and ferromagnetism can coexist in this regime. We identify signatures of the competition between superconductivity and ferromagnetism in a number of quantities: ground-state spin, conductance fluctuations when the grain is weakly coupled to external leads and the thermodynamic properties of the grain, such as heat capacity and spin susceptibility.

description: OBJECTIVES: Decline in cognitive control is one of the primary cognitive changes in normal aging. Reaching a consensus regarding the nature of these age-related changes, however, is complicated by the complexity of cognitive control as a construct. METHODS: Healthy older and younger adults participated in a multifactorial test of cognitive control. Within participants, the procedure varied as a function of the amount contextual load, episodic load, and response-conflict load present. RESULTS: We found that older adults showed impaired performance relative to younger adults. We also found, however, that the response selection process underlying the response-conflict manipulation was a major moderator of age-related differences in both the contextual and episodic load conditions-suggesting a hierarchical organization. DISCUSSION: These findings are consistent with previous findings, suggesting that deficits in cognitive control in older adults are directly related to the resolution of response-conflict and that other apparent deficits may be derivative upon the more basic response-conflict related deficit.

description: We investigate spectral quantities of quantum graphs by expanding them as sums over pseudo orbits, sets of periodic orbits. Only a finite collection of pseudo orbits which are irreducible and where the total number of bonds is less than or equal to the number of bonds of the graph appear, analogous to a cut off at half the Heisenberg time. The calculation simplifies previous approaches to pseudo orbit expansions on graphs. We formulate coefficients of the characteristic polynomial and derive a secular equation in terms of the irreducible pseudo orbits. From the secular equation, whose roots provide the graph spectrum, the zeta function is derived using the argument principle. The spectral zeta function enables quantities, such as the spectral determinant and vacuum energy, to be obtained directly as finite expansions over the set of short irreducible pseudo orbits.

description: Activity of inhibitory neuron with delayed feedback is considered in the framework of point stochastic processes. The neuron receives excitatory input impulses from a Poisson stream, and inhibitory impulses from the feedback line with a delay. We investigate here, how does the presence of inhibitory feedback affect the output firing statistics. Using binding neuron (BN) as a model, we derive analytically the exact expressions for the output interspike intervals (ISI) probability density, mean output ISI and coefficient of variation as functions of model's parameters for the case of threshold 2. Using the leaky integrate-and-fire (LIF) model, as well as the BN model with higher thresholds, these statistical quantities are found numerically. In contrast to the previously studied situation of no feedback, the ISI probability densities found here both for BN and LIF neuron become bimodal and have discontinuity of jump type. Nevertheless, the presence of inhibitory delayed feedback was not found to affect substantially the output ISI coefficient of variation. The ISI coefficient of variation found ranges between 0.5 and 1. It is concluded that introduction of delayed inhibitory feedback can radically change neuronal output firing statistics. This statistics is as well distinct from what was found previously (Vidybida & Kravchuk, 2009) by a similar method for excitatory neuron with delayed feedback.

Cerebrovascular disease--Risk factors
Cognition

description: We investigated the relationship between risk factors for cerebrovascular disease and cognitive function in 249 stroke-free community volunteers (age, 70.8±6.7 years; education, 12.3±4.6 years) who were given tests of memory, language, visuospatial, abstract reasoning, and attentional skills. Using logistic regression analyses, we examined hypertension, diabetes mellitus, myocardial infarction, angina, hypercholesterolemia, and cigarette smoking as potential correlates of performance within these cognitive domains. Controlling for demographic factors within the logistic models, diabetes mellitus was a significant independent correlate of abstract reasoning deficits (odds ratio, 10.9; 95% confidence interval, 2.2 to 54.9) and visuospatial dysfunction (odds ratio, 3.5; confidence interval, 1.2 to 10.7), while hypercholesterolemia was a significant independent correlate of memory dysfunction (odds ratio, 3.0; confidence interval, 1.4 to 6.6). Prolonged exposure to vascular risk factors such as diabetes mellitus and hypercholesterolemia may lead to atherosclerotic disease, possibly resulting in "silent" infarctions or impaired cerebral blood flow and a decline in cognitive functioning.
Role of non-decay fungi on the weathering of wood
Creators: name: Hernandez, Vicente
Publisher: name: University of British Columbia
Year: 2012

description: In this thesis I hypothesized that the graying of wood exposed outdoors is due to the presence of melanized fungi that are relatively resistant to UV-light. To test this hypothesis I examined the color and chemical changes at wood surfaces exposed to the weather and filtered solar radiation, isolated and identified fungi colonizing wood samples by DNA analysis and microscopy and examined the survival, growth and melanin production of staining fungi under UV, visible or no light. The ability of isolated fungi to decay wood was also tested by evaluating changes in the microstructure, mechanical, viscoelastic and chemical properties of spruce and lime wood incubated with fungi. Finally, I tested a novel non-biocidal approach to reduce the staining of wood by fungi, which employed melanin biosynthesis inhibitors (MBIs). My results support the general hypothesis (above) and reveal that weathered wood surfaces are grayed by the interactive effects of solar radiation and fungal colonization. UV-radiation increased the production of melanin by the fungus most frequently isolated from weathered wood (Aureobasidium pullulans), which leads to darker weathered wood surfaces. Decay tests showed that species of Cladosporium, Coniochaeta, Epicoccum, Lewia, Mollisia and Phialocephala, were able to degrade wood tissues. In artificial media, MBIs in combination with UV-radiation blocked the growth of staining fungi, but at wood surfaces MBIs reduced fungal staining irrespective of the type of light that samples were exposed to. I conclude that UV-radiation and melanized fungi interact to influence the color of weathered wood surfaces. Degradation of wood by surface fungi is possible, but the extent of damage probably depends on the presence of conditions that favor microbial decay. Finally, the use of MBIs is a promising approach to control graying of weathered wood surfaces, but further research is required to optimize the treatments and test them outdoors.

description: We show that under the presence of a static magnetic field the photon eigen-frequencies of a circular gyromagnetic cylinder experience a splitting that is proportional to the angular momentum density of light at the cylinder surface. Such a splitting of the photonic states is similar to the Zeeman splitting of electronic states in atoms. This leads to some unusual decoupling properties of these non-degenerate photonic angular momentum states, which are demonstrated through numerical simulations.

On the dynamics of classicalization

description: We discuss the mechanism through which classicalization may occur during the collapse of a spherical field configuration modelled as a wavepacket. We demonstrate that the phenomenon is associated with the dynamical change of the equation of motion from a second-order partial differential equation of hyperbolic to one of elliptic type. Within this approach, we rederive the known expression for the classicalization radius. We also find indications that classicalization is associated with the absence of wave propagation at distances below the classicalization radius and the generation of shock fronts. The full quantitative picture can be obtained only through the numerical integration of a partial differential equation of mixed type.

Mussaenda vidalii

description: Mussaenda vidalii Elmer, LPB 3 (1911) 993. Materials examined. Table 2. Small shrub about 1 m high. Leaves ovate, 2–2.5 × 1.2–1.5 cm, membranous, densely hirsute on both sides especially on the venations. Inflorescences terminal, spreading corymbs. Calyx with a single swollen lobe (calycophyll), white, broadly ovate, 6–8 × 3–8 cm, sparsely pubescent. Corolla infundibular, lobes 4–6 mm, tube 2–3 cm, orange to yellow. Fruits ellipsoid, 1–2 cm, with dense warts. This species is often observed on secondary forests or in open-regrowth forests of Eastern Samar. While the type specimen of M. vidalii is described as a scandent shrub, most collections of this species are represented by erect shrubs or small trees. In their revision, Alejandro et al. (2015), they noted phenotypic variability of the habit of this species, which ranges from scandent shrubs to small, erect shrubs or trees.

description: The level density of 2+ states in 40Ca has been extracted in the energy region of the isoscalar giant quadrupole resonance (ISGQR) from a fluctuation analysis of high energy-resolution p,p') data taken at incident energies of 200 MeV at the K600 magnetic spectrometer of iThemba LABS, South Africa. Quasi-free scattering cross sections were calculated to estimate their role as a background contribution to the spectra and found to be small. The shape of the background was determined from the discrete wavelet transform of the spectra using a biorthogonal wavelet function normalized at the lowest particle separation threshold. The experimental results are compared to widely used phenomenological and microscopic models.

description: Recent studies suggest that individual hippocampal subregions perform distinct cognitive operations and are differentially targeted by aging and disease. Although originally developed to assess global hippocampal function, whether performance on standard memory tests used in neuropsychological batteries is associated with individual hippocampal subregions remains unknown. Here we addressed this issue by imaging 210 neuropsychologically characterized subjects using a high-resolution variant of functional magnetic resonance imaging that generates maps reflective of basal hippocampal metabolism. Regression analysis revealed memory tests that differentially associate with two hippocampal subregions, the entorhinal cortex (EC) and the dentate gyrus (DG). Whereas performance on the delayed retention component of the Selective Reminding Test was associated with the EC, performance on the recognition component of the Benton Visual Retention Test (BVRT) was associated with the DG. Furthermore, elevation in blood glucose, previously shown to target the DG, was found to correlate selectively with the recognition component of the BVRT. These findings provide further evidence that the hippocampal subregions perform distinct roles, and, interpreted in the context of previous neuropsychological and imaging studies, confirm that aging and Alzheimer's disease target different hippocampal subregions.
