Symmetric and asymmetric Holmboe instabilities in stratified shear flows
Creators: name: Yang, Jiankang
Publisher: name: University of British Columbia
Year: 2022

description: Flows in the oceans and the atmosphere often involve the horizontal shearing of stably stratified density layers. These shear layers are subject to hydrodynamic instabilities that cause the transition from laminar to turbulent flow. When a density interface is sharper than the velocity interface, the Holmboe instability can arise. In this thesis, the dynamics and mixing of the Holmboe instability are investigated theoretically, numerically and in the laboratory. First, the spatial evolution of the Holmboe instability along an arrested salt wedge is investigated both in laboratory experiments and using linear stability analysis. The spatial evolution is dependent on the variation in the mean velocity and density profiles along the length of the salt wedge. The linear stability analysis incorporates this variation and predicts the growth rate, wavelength, phase speed and wave steepness of the Holmboe instability along the length of the salt wedge. These predictions are consistent with the laboratory measurements. The Reynolds stress ellipses associated with Holmboe instabilities are investigated using linear stability analysis, single wavelength simulations, multiple wavelength simulations, and a laboratory experiment. Conventionally, only the statistics of horizontal and vertical velocity perturbation pairs, (u',w'), are used to show the degree of anisotropy in perturbation fields. Here, a theory-based approach is used to investigate this anisotropy. Linear stability analysis predicts the aspect ratio of the major and minor axes and the orientation angle of the Reynolds stress ellipses, and thus predicts the resultant Reynolds stresses. Finally, the influence of initial perturbations on the mixing generated by Holmboe instabilities is examined. Initial perturbations are commonly used in direct numerical simulations to stimulate the shear instability of stratified fluids. The amplitudes of the primary and subharmonic Holmboe modes determine the development of the Holmboe instabilities. The excitation of the subharmonic mode induces the merging of the primary Holmboe mode, and further increases the amplitude of Holmboe waves and the overall mixing.

description: The transition processes from monogenetic volcanoes to composite volcanoes are poorly understood. The Late Pleistocene to Holocene intraplate monogenetic Wulanhada Volcanic Field (WVF) in northern China provides a snapshot of such a transition. Here we present petrographic observations, mineral chemistry, bulk rock major and trace element data, thermobarometry, and a partial melting model for the WVF to evaluate the lithology and partial melting degree of the mantle source, the crystallization conditions, and pre-eruptive magmatic processes occurring within the magma plumbing system. The far-field effect of India-Eurasia collision resulted in a relatively high degree (10 %-20 %) of partial melting of a carbonate-bearing eclogite (~ 3 wt % carbonate; Gt/Cpx ≈ 2 : 8, where Gt denotes garnet and Cpx denotes clinopyroxene) followed by interaction with ambient peridotite. The primary melts ascended to the depth of the Moho (~ 33-36 km depth), crystallized olivine, clinopyroxene and plagioclase at the temperature of 1100-1160 °C with the melt water contents of 1.1 wt %- 2.3 wt %. Part of the primary melt interacted with the lithospheric mantle during ascent, resulting in an increase in the MgO contents and a decrease in the alkaline contents. The modified magma was subsequently directly emplaced into the middle crust (~ 23-26 km depth) and crystallized olivine, clinopyroxene and plagioclase at the temperature of 1100-1160 °C. The primary melts from the same mantle sources migrated upward to the twolevel magma reservoirs to form minerals with complex textures (including reverse and oscillatory zoning and sieve texture). Magma erupted along the NE-SW-striking basement fault and the NW-SE-striking Wulanhada- Gaowusu fault in response to the combined effects of regional tectonic stress and magma replenishment. The crustal magma reservoir in the WVF may represent a snapshot of the transition from monogenetic volcanoes to composite volcanoes. It is possible to form a composite volcano with large magma volumes and complex compositions if the magma is continuously supplied from the source and experiences assimilation and fractional crystallization processes in the magma plumbing system at crustal depth.
PT-Symmetric Sinusoidal Optical Lattices at the Symmetry-Breaking Threshold

description: The $PT$ symmetric potential $V_0[\cos(2πx/a)+iλ\sin(2πx/a)]$ has a completely real spectrum for $λ\le 1$, and begins to develop complex eigenvalues for $λ>1$. At the symmetry-breaking threshold $λ=1$ some of the eigenvectors become degenerate, giving rise to a Jordan-block structure for each degenerate eigenvector. In general this is expected to result in a secular growth in the amplitude of the wave. However, it has been shown in a recent paper by Longhi, by numerical simulation and by the use of perturbation theory, that for a broad initial wave packet this growth is suppressed, and instead a saturation leading to a constant maximum amplitude is observed. We revisit this problem by explicitly constructing the Bloch wave-functions and the associated Jordan functions and using the method of stationary states to find the dependence on the longitudinal distance $z$ for a variety of different initial wave packets. This allows us to show in detail how the saturation of the linear growth arises from the close connection between the contributions of the Jordan functions and those of the neighbouring Bloch waves.

description: Due to its dynamism, Globalisation has impacted every aspect of life across the globe. Whether Nigeria’s educational institutions are prepared or not, the youth, like their peers worldwide are living in an increasingluy globalized world. However, despite its indispensible strategic role in national development, quite iften, when the word globalisation is mentioned, education is not the the first thing that comes to mind. The colllective social oversight has led to misplaced priority in education policies, failing educational system and seeming disconnection from the global community in critical thinking, analytical and problem-solving skills. From a qualitative research orientation, this paper uses critical textual analyses of existing relevant literature to explore globalisation impact on Nigeria’s education. The specific goal her is aimed at crystalizing and highlighting what educators need to do at the local levels to improve the quality of our education and preoovide our citizenry a fair opportunity at competing on the global stage – in all sphere and endeavor. The paper argues that like children everywhere in the world, Nigerian students need the skills to function as global citizens. They need to acquire global competency skills.

description: The suppression of superconductivity by nonmagnetic disorder is investigated systematically in the organic superconductor $κ$-(BEDT-TTF)$_2$Cu(NCS)$_2$. We introduce a nonmagnetic disorder arising from molecule substitution in part with deuterated BEDT-TTF or BMDT-TTF for BEDT-TTF molecules and molecular defects introduced by X-ray irradiation. A quantitative evaluation of the scattering time $τ_{\rm dHvA}$ is carried out by de Haas-van Alphen (dHvA) effect measurement. A large reduction in $T_{\rm c}$ with a linear dependence on $1/τ_{\rm dHvA}$ is found in the small-disorder region below $1/τ_{\rm dHvA} \simeq$ 1 $\times$ 10$^{12}$ s$^{-1}$ in both the BMDT-TTF molecule-substituted and X-ray-irradiated samples. The observed linear relation between $T_{\rm c}$ and $1/τ_{\rm dHvA}$ is in agreement with the Abrikosov-Gorkov (AG) formula, at least in the small-disorder region. This observation is reasonably consistent with the unconventional superconductivity proposed thus far for the present organic superconductor. A deviation from the AG formula, however, is observed in the large-disorder region above $1/τ_{\rm dHvA} \simeq$ 1 $\times$ 10$^{12}$ s$^{-1}$, which reproduces the previous transport study (J. G. Analytis {\it et al.}: Phys. Rev. Lett. {\bf 96} (2006) 177002). We present some interpretations of this deviation from the viewpoints of superconductivity and the inherent difficulties in the evaluation of scattering time.

description: An anisotropic power spectrum will have a clear signature in the 21cm radiation from high-redshift hydrogen. We calculate the expected power spectrum of the intensity fluctuations in neutral hydrogen from before the epoch of reionization, and predict the accuracy to which future experiments could constrain a quadrupole anisotropy in the power spectrum. We find that the Square Kilometer Array will have marginal detection abilities for this signal at z~17 if the process of reionization has not yet started; reionization could enhance the detectability substantially. Pushing to higher redshifts and higher sensitivity will allow highly precise (percent level) measurements of anisotropy.

description: We study hot carrier transport under magnetic fields up to 15 T in suspended graphitic multilayers through differential conductance (dI/dV) spectroscopy. Distinct high-energy dI/dV anomalies have been observed and shown to be related to intrinsic phonon-emission processes in graphite. The evolution of such dI/dV anomalies under magnetic fields is further understood as a consequence of inter-Landau level cyclotron-phonon resonance scattering. The observed magneto-phonon effects not only shed light on the physical mechanisms responsible for high-current transport in graphitic systems, but also offer new perspectives for optimizing performance in graphitic nano-electronic devices.

Superspace Formulation in a Three-Algebra Approach to D=3, N=4,5 Superconformal Chern-Simons Matter Theories

Year: 2010

description: We present a superspace formulation of the D=3, N=4,5 superconformal Chern-Simons Matter theories, with matter supermultiplets valued in a symplectic 3-algebra. We first construct an N=1 superconformal action, and then generalize a method used by Gaitto and Witten to enhance the supersymmetry from N=1 to N=5. By decomposing the N=5 supermultiplets and the symplectic 3-algebra properly and proposing a new super-potential term, we construct the N=4 superconformal Chern-Simons matter theories in terms of two sets of generators of a (quaternion) symplectic 3-algebra. The N=4 theories can also be derived by requiring that the supersymmetry transformations are closed on-shell. The relationship between the 3-algebras, Lie superalgebras, Lie algebras and embedding tensors (proposed in [E. A. Bergshoeff, O. Hohm, D. Roest, H. Samtleben, and E. Sezgin, J. High Energy Phys. 09 (2008) 101.]) is also clarified. The general N=4,5 superconformal Chern-Simons matter theories in terms of ordinary Lie algebras can be rederived in our 3-algebra approach. All known N=4,5 superconformal Chern-Simons matter theories can be recovered in the present superspace formulation for super-Lie-algebra realization of symplectic 3-algebras.

description: "Noise-induced volatility" refers to a phenomenon of increased level of fluctuations in the collective dynamics of bistable units in the presence of a rapidly varying external signal, and intermediate noise levels. The archetypical signature of this phenomenon is that --beyond the increase in the level of fluctuations-- the response of the system becomes uncorrelated with the external driving force, making it different from stochastic resonance. Numerical simulations and an analytical theory of a stochastic dynamical version of the Ising model on regular and random networks demonstrate the ubiquity and robustness of this phenomenon, which is argued to be a possible cause of excess volatility in financial markets, of enhanced effective temperatures in a variety of out-of-equilibrium systems and of strong selective responses of immune systems of complex biological organisms. Extensive numerical simulations are compared with a mean-field theory for different network topologies.

description: If supersymmetry (SUSY) will be discovered, successful models of flavour not only have to provide an explanation of the flavour structure of the Standard Model fermions, but also of the flavour structure of their scalar superpartners. We discuss aspects of such "SUSY flavour" models, towards predicting both flavour structures, in the context of supergravity (SUGRA). We point out the importance of carefully taking into account SUSY-specific effects, such as 1-loop SUSY threshold corrections and canonical normalization, when fitting the model to the data for fermion masses and mixings. This entangles the flavour model with the SUSY parameters and leads to interesting predictions for the sparticle spectrum. We demonstrate these effects by analyzing an example class of flavour models in the framework of an SU(5) Grand Unified Theory with a family symmetry with real triplet representations. For flavour violation through the SUSY soft breaking terms, the class of models realizes a scheme we refer to as "Trilinear Dominance", where flavour violation effects are dominantly induced by the trilinear terms.

description: Several recent studies have reported the detection of an anomalous color spread along the red giant branch (RGB) of some globular clusters (GC) that appears only when color indices including a near ultraviolet band (such as Johnson U or Stromgren u) are considered. This anomalous spread in color indexes such as U-B or c_{y} has been shown to correlate with variations in the abundances of light elements such as C, N, O, Na, etc., which, in turn, are generally believed to be associated with subsequent star formation episodes that occurred in the earliest few 10^{8} yr of the cluster's life. Here we use publicly available u, g, r Sloan Digital Sky Survey photometry to search for anomalous u-g spreads in the RGBs of nine Galactic GCs. In seven of them (M 2, M 3, M 5, M 13, M 15, M 92 and M 53), we find evidence of a statistically significant spread in the u-g color, not seen in g-r and not accounted for by observational effects. In the case of M 5, we demonstrate that the observed u-g color spread correlates with the observed abundances of Na, the redder stars being richer in Na than the bluer ones. In all the seven clusters displaying a significant u-g color spread, we find that the stars on the red and blue sides of the RGB, in (g, u-g) color magnitude diagrams, have significantly different radial distributions. In particular, the red stars (generally identified with the second generation of cluster stars, in the current scenario) are always more centrally concentrated than blue stars (generally identified with the first generation) over the range sampled by the data (0.5r_{h} < r < 5r_{h}), in qualitative agreement with the predictions of some recent models of the formation and chemical evolution of GCs. Our results suggest that the difference in the radial distribution between first and second generation stars may be a general characteristic of GCs.

description: We give some evidences of the AGT-W relation between SU(3) quiver gauge theories and A_2 Toda theory. In particular, we derive the explicit form of 5-point correlation functions in the lower orders and confirm the agreement with Nekrasov's partition function for SU(3)xSU(3) quiver gauge theory. The algorithm to derive the correlation functions can be applied to general n-point function in A_2 Toda theory which will be useful to establish the relation for more generic quivers. Partial analysis is also given for SU(3)xSU(2) case and we comment on some technical issues which need clarification before establishing the relation.

description: This thesis investigates the causes and consequences of regional disparities in Germany and consists of three self-contained essays. Each essay utilizes spatially fine-grained microdata for Germany. They differ in focus and methodology but are all inseparably related through the spatial level of analysis. Chapter one provides introductory remarks. The second chapter studies the relative impact of two distinct local business tax instruments on workers' wages. While the primary contribution is the estimation of the effect of a revenue-neutral substitution between two tax instruments, the chapter provides evidence of the amplification of cross-regional wage disparities through local taxation. The third chapter relates regional unemployment differentials to worker flows, recovers underlying structural variations across regions, and investigates the impact of optimal local labor market policies that attenuate within market inefficiencies and balance the adverse effect of unemployment insurance benefits. The fourth chapter studies the characteristics of individual inter-regional migration decisions of employed workers and examines the relationship between individual earnings gains and location characteristics. Chapter five concludes.

These simulations are the first to include the feedback effects protostellar outflows, as well as protostellar radiative heating and radiation pressure exerted on the infalling, dusty gas. We find that that outflows evacuate polar cavities of reduced optical depth through the ambient core. These enhance the radiative flux in the poleward direction so that it is 1.7 to 15 times larger than that in the midplane. As a result the radiative heating and outward radiation force exerted on the protostellar disk and infalling cloud gas in the equatorial direction are greatly diminished. The simultaneously reduces the Eddington radiation pressure barrier to high-mass star formation and increases the minimum threshold surface density for radiative heating to suppress fragmentation compared to models that do not include outflows. The strength of both these effects depends on the initial core surface density. Lower surface density cores have longer free-fall times and thus massive stars formed within them undergo more Kelvin contraction as the core collapses, leading to more powerful outflows. Furthermore, in lower surface density clouds the ratio of the time required for the outflow to break out of the core to the core free-fall time is smaller, so that these clouds are consequently influenced by outflows at earlier stages of collapse. As a result, outflow effects are strongest in low surface density cores and weakest in high surface density one. We also find that radiation focusing in the direction of outflow cavities is sufficient to prevent the formation of radiation pressure-supported circumstellar gas bubbles, in contrast to models which neglect protostellar outflow feedback.

description: We present a linear scaling formulation for the solution of the all-electron Coulomb problem in crystalline solids. The resulting method is systematically improvable and well suited to large-scale quantum mechanical calculations in which the Coulomb potential and energy of a continuous electronic density and singular nuclear density are required. Linear scaling is achieved by introducing smooth, strictly local neutralizing densities to render nuclear interactions strictly local, and solving the remaining neutral Poisson problem for the electrons in real space. While the formulation includes singular nuclear potentials without smearing approximations, the required Poisson solution is in Sobolev space $H^1$, as required for convergence in the energy norm. We employ enriched finite elements, with enrichments from isolated atom solutions, for an efficient solution of the resulting Poisson problem in the interacting solid. We demonstrate the accuracy and convergence of the approach by direct comparison to standard Ewald sums for a lattice of point charges, and demonstrate the accuracy in all-electron quantum mechanical calculations with an application to crystalline diamond.

description: We compute the characteristic Cartan connection associated with a system of third order ODEs. Our connection is different from Tanaka normal one, but still is uniquely associated with the system of third order ODEs. This allows us to find all fundamental invariants of a system of third order ODEs and, in particular, determine when a system of third order ODEs is trivializable. As application differential invariants of equations on circles in ${\mathbb R}^n$ are computed.

description: We use our new, flux-calibrated stellar population model of absorption-line indices to derive ages, metallicities, and various element abundance ratios from integrated light spectroscopy of galactic globular clusters. The ages agree well with the literature and are all consistent with the age of the universe. There is a considerable scatter, though, and we obtain systematically larger ages than CMD determinations mostly for metal-rich globular clusters. The metallicities agree well with literature values on the Zinn & West scale, if we adopt iron abundance [Fe/H] for those clusters whose ages agree with the CMD ages. It turns out that the derivation of individual element abundance ratios is not reliable at [Fe/H]

Cancer pathways are deranged in Mucopolysaccharidosis
Creators: name: Silva, Gerda Cristal Villalba

Year: 2020

description: Defects in activity of lysosomal hydrolases involved in glycosaminoglycan degradation lead to a group of lysosomal storage diseases called Mucopolysaccharidosis (MPS). In MPS, secondary cell disturbance affects pathways common to cancer. This work aims to investigate the differential expression of cancer pathways in MPS datasets available in public functional genomics data repository, such as GEO (Gene Expression Omnibus) and ArrayExpress. We performed Gene Ontology analysis with QuickGo and KEGG annotations, and the network was constructed with ShinyGo (v0.61) based on hypergeometric distribution followed by FDR correction. We selected 12 datasets, being 2 of MPS I; 1 from MPS II; 1 from MPS IIIA; 3 MPS IIIB; 1 MPS VI; and 4 from MPS VII. The most abundant ontologies found were PI3K−Akt signaling pathway; MAPK signaling pathway; Ras signaling pathway; Rap1 signaling pathway and cAMP signaling pathway. We hypothesize that these signaling pathways are altered because glycosaminoglycans play an essential role in the composition of the extracellular matrix, helping to regulate processes such as metabolic signaling, apoptosis, cell migration, adhesion, and antigen presentation. Understanding these biological processes may help us look for new biomarkers for these rare metabolic diseases.
Normalizing Wastewater Data

Publisher: name: Zenodo
Year: 2023
Subjects: wastewater-based epidemiology

description: The choice of normalization approach is highly-dependent on the presumed environmental effects and practical constraints of the specific wastewater-based epidemiology (WBE) application, and no single answer is best. Presenting data without normalization can also be a valid approach. Normalization refers to the process of adjusting wastewater data so that changes in reported concentrations of a target analyte or biomarker better reflect meaningful changes in the community. Normalization can be used to account for a variety of environmental effects, including in-lab, in-sewer, and in-human effects. In this white paper, we propose a framework for selecting and evaluating normalization approaches for any WBE application. At minimum, a normalization approach must be theoretically justified and logistically practical. Additionally, normalization approaches may provide direct estimates of the effect being accounted for, improve representation of external trends, and/or improve the interpretability of the data. Normalization works by scaling laboratory measurements using either (i) marker normalization, in which markers measured in the same sample as the analyte of interest are used to account for the environmental effects, or
 (ii) metadata normalization, in which metadata derived from the community or other external sources is used to account for effects. Marker normalization can be applied to any wastewater sample regardless of where it was collected and without the need for additional metadata like flow or population, making it an extremely versatile normalization approach. It can address all types of environmental effects, unlike metadata normalization which is limited to in-sewer and in-human effects. However, marker normalization requires additional lab measurements and may therefore be less practical than metadata normalization for some applications.
A multi-scale and GIS-based investigation of climate change effects on urban climate and building energy demand for the city of Stuttgart

description: This paper presents a multi-scale and GIS-based investigation approach whose goal is to quantify the consequences of a climate change scenario (2041-2050) on the energy demand of buildings by comparison to a past scenario (1991-2000) applied to the city of Stuttgart. Energy simulations are made at building scale while taking into account the surrounding urban microclimates. The investigation method combines 1) numerical modelling using TEB and TRNSYS, 2) design of experiments (DOE) statistical analysis for data pre- and post-processing, and 3) GIS techniques. The outcome of the study is the heating and cooling energy demands summed up at city block level and displayed in 2D GIS maps. The results reveal that i) warmer urban microclimates occur, ii) with less heating and more cooling of buildings required if future versus past reference climate data are used. Spatial differences in the results within the city are found depending on the geometrical and thermal characteristics of the individual city blocks and buildings.

description: We theoretically examine the orbital excitations coupled to the spin degree of freedom in the parent state of the iron-arsenide superconductor, based on the calculation in a five-band itinerant model. The calculated Fe $L_3$-edge resonant inelastic x-ray scattering (RIXS) spectra disclose the presence of spin-flip excitations involving several specific orbitals. Magnon excitations predominantly composed of a single orbital component can be seen in experiments, although its spectral weight is smaller than spin-flipped interorbital high-energy excitations. The detailed polarization and momentum dependence is also discussed with predictions for the experiments.
