A LABORATORY PROTOCOL FOR THE ANALYSIS OF NATURAL GAS HYDRATES
Creators: name: Lu, Hailong

Publisher: name: The University of British Columbia
Year: 2008

description: For a number of years the NRC group has been working on a laboratory protocol for the analysis of gas hydrate that has been recovered from various natural sites. The expectation was that a comprehensive set of techniques would become available for the general use of hydrate researchers around the world. With the current set of available techniques a good picture of natural gas hydrates can be obtained, although the emerging complexity of the hydrate-mineral system still demands additional work. Here we present a suite of techniques that will take a researcher from preservation techniques to hydrate occurrence, gas/water/sediment ratios, gas and isotope analysis, P-T behaviour, structure, composition, degree of water conversion to hydrate, hydrate homogeneity and decomposition behaviour. As more detailed studies become possible a variety of more subtle features are revealed, for instance the role of minor gas components in hydrate stability, decomposition behaviour and heterogeneity in structure and composition.

description: The energy spectrum of the three-particle Hamiltonian obtained by replacing the two-body trigonometric potential of the Sutherland problem by a three-body one of a similar form is derived. When expressed in appropriate variables, the corresponding wave functions are shown to be expressible in terms of Jack polynomials. The exact solvability of the problem with three-body interaction is explained by a hidden sl(3,\R) symmetry.

description: There have been ample studies of the many phases of H2O in both its solid and low pressure liquid states, and the transitions between them. Using molecular dynamics simulations we address the hitherto unexplored deeply supercritical pressures, where no qualitative transitions are thought to take place and where all properties are expected to vary smoothly. On the basis of these simulations we predict that water at supercritical pressures undergoes a structural crossover across the Frenkel line at pressures as high as 45 times the critical pressure. This provides a new insight into the water phase diagram and establishes a link between the structural and dynamical properties of supercritical water. Specifically, the crossover is demonstrated by a sharp and pronounced at low pressures, and smooth at high pressures, signified by changes in the pair distribution functions and local coordination which coincide with the dynamical transition (the loss of all oscillatory molecular motion) at the Frenkel line on the phase diagram.

description: Micromechanical adhesion force measurements were performed on tetrahydrofuran (THF) hydrate particles in n-decane. The experiments were performed at atmospheric pressure over the temperature range 261–275 K. A scoping study characterized the effects of temperature, anti-agglomerants, and interfacial energy on the particle adhesion forces. The adhesion force between hydrate particles was found to increase with temperature and the interfacial energy of the surrounding liquid. The adhesion force of hydrates was directly proportional to the contact time and contact force. Both sorbitan monolaurate (Span20) and poly-N-vinyl caprolactam (PVCap) decreased the adhesion force between the hydrate particles. The measured forces and trends were explained by a capillary bridge between the particles.

Bulk viscosity of CO$_2$ from Rayleigh-Brillouin lightscattering spectroscopy at 532 nm

description: Rayleigh-Brillouin scattering spectra of CO$_2$ were measured at pressures ranging from 0.5 to 4~bar, and temperatures from 257 to 355~K using green laser light (wavelength 532~nm, scattering angle of 55.7$^\circ$). These spectra were compared to two lineshape models, which take the bulk viscosity as a parameter. One model applies to the kinetic regime, i.e. low pressures, while the second model uses the continuum, hydrodynamic approach and takes the rotational relaxation time as a parameter, which translates into the bulk viscosity. We do not find a significant dependence of the bulk viscosity with pressure or temperature. At pressures where both models apply we find a consistent value of the ratio of bulk viscosity over shear viscosity $η_b/η_s = 0.41 \pm 0.10$. This value is four orders of magnitude smaller than the common value that is based on the damping of ultrasound, and signifies that in light scattering only relaxation of rotational modes matters, while vibrational modes remain 'frozen'.

description: Let $n$ be a positive integer. We introduce a concept, which we call the $n$-filling property, for an action of a group on a separable unital $C^*$-algebra $A$. If $A=C(Ω)$ is a commutative unital $C^*$-algebra and the action is induced by a group of homeomorphisms of $Ω$ then the $n$-filling property reduces to a weak version of hyperbolicity. The $n$-filling property is used to prove that certain crossed product $C^*$-algebras are purely infinite and simple. A variety of group actions on boundaries of symmetric spaces and buildings have the $n$-filling property. An explicit example is the action of $Γ=SL_n({\bf Z})$ on the projective $n$-space.

title: Community Parameters of Auchenorrhyncha (Hemiptera: Insect) Along Altitudinal Gradients in Subtropical and Tropical Rainforests in Australia
Creators: name: Dem, Francesca Florence
Publisher: name: Griffith University
Year: 2016

description: Gradients in altitude are used frequently to understand how species respond to changes in local climatic conditions and are therefore a robust tool for predicting how species and communities in montane environments may respond to changes in climate. It is important that we understand how species richness patterns and interactions are affected by current changes in climate if we are to make sensible predictions about how biodiversity and ecosystem function will be affected by climate change. Further, while studies have shown a strong gradients in species richness and species turnover that accompany altitude, little is known about how species at different heights in forests and how plant-insect herbivore interactions respond to altitude. This challenge has been addressed here by examining the changing distribution patterns of the taxonomic group, Auchenorrhyncha, which are an important group of plant sucking herbivores, with altitude, in vertical forest columns and of their associated host plants. Herbivorous insects, including leafhoppers and planthoppers interact with their host plants in complex networks, but relatively little is known about how these relationships will be and are being affected by changes in climate. In order to determine how altitudinal changes in climatic conditions affect distribution patterns of Auchenorrhyncha, I quantified these communities along two altitudinal gradients, one in eastern Australian subtropical rainforest and the other in northern Australian tropical rainforest.

description: We revisit Matui-Sato's notion of property (SI) for C*-algebras and C*-dynamics. More specifically, we generalize the known framework to the case of C*-algebras with possibly unbounded traces. The novelty of this approach lies in the equivariant context, where none of the previous work allows one to (directly) apply such methods to actions of amenable groups on highly non-unital C*-algebras, in particular to establish equivariant Jiang-Su stability. Our main result is an extension of an observation by Sato: For any countable amenable group $Γ$ and any non-elementary separable simple nuclear C*-algebra $A$ with strict comparison, every $Γ$-action on $A$ has equivariant property (SI). A more general statement involving relative property (SI) for inclusions into ultraproducts is proved as well. As a consequence we show that if $A$ also has finitely many rays of extremal traces, then every $Γ$-action on $A$ is equivariantly Jiang-Su stable. We moreover provide applications of the main result to the context of strongly outer actions, such as a generalization of Nawata's classification of strongly outer automorphisms on the (stabilized) Razak-Jacelon algebra.

 Records from India. ASSAM: Ghorajan, Hiragota, Akhepeti, Bamoni— Sharma & Sharma (2008); ODISHA: Cuttack— Sharma (1987); GENERAL RECORD: Naidu & Rao (2004).
 Habitat (as in Indian records). Freshwater; among aquatic vegetation.
 Distribution. Published records of this species are from the USA and India.
 Remarks. The species derives its name from the cyan colour of the gut, very likely due to the cyanobacteria on which it feeds on. The bluish colouration was reported in the original description of the species by Brunson (1950), and has been recently observed in specimens from the US collected by Dr. Bas Kooijmanone (see picture at http://www.gastrotricha.unimore.it/picturegallery.htm). One of us (MAT) has seen gastrotrichs with a bluish gut content during his expedition in South Africa (e.g., Todaro et al. 2013); size and general appearance of the South African specimens are very similar to the American species (MAT, unpublished). Gastrotrich specimens identified as C. gastrocyaneus have been found twice in India, respectively by Sharma (1987) and Sharma & Sharma (2008). Surprisingly neither Sharma & Sharma (1990) nor Purushothaman (2017) did mention this species name in their lists of freshwater Gastrotricha from India.
 Morphometric data provided for the Indian specimens are very scanty and the authors never mentioned these gastrotrichs to have a cyan-coloured intestine, which is a trademark trait for the species. Because of the poor morphological data and in the absence of any reference to the colour of their gut, we consider the identification performed so far of these Indian specimens to be unreliable; consequently, C. gastrocyaneus should not be considered part of the Indian fauna.

description: Convection-dominated accretion flows (CDAF) are expected to have a shallower density profile and a higher radiation efficiency as compared to advection-dominated accretion flows (ADAF). Both solutions have been developed to account for the observed properties of the low luminosity, high temperature X-ray sources believed to involve accretion onto massive black holes. Self-similar CDAFs also have steeper poloidal density gradients and temperatures close to the virial temperature. All these characteristics make CDAFs more capable of producing polar outflows driven by Compton heating as compared to other classical accretion disks. We investigate the conditions for producing such outflows in CDAFs and look for the mass accretion rate, or, equally, the luminosity of CDAFs for which such outflows will exist. When the electron temperature saturates around 10^11 K at the inner region, polar outflows are probable for 8x10^-7

description: We devise a geometric description of bounded systems at criticality in any dimension $d$. This is achieved by altering the flat metric with a space dependent scale factor $γ(x)$, $x$ belonging to a general bounded domain $Ω$. $γ(x)$ is chosen in order to have a scalar curvature to be constant and negative, the proper notion of curvature being -- as called in the mathematics literature -- the fractional Q-curvature. The equation for $γ(x)$ is found to be the Fractional Yamabe Equation (to be solved in $Ω$) that, in absence of anomalous dimension, reduces to the usual Yamabe Equation in the same domain. From the scale factor $γ(x)$ we obtain novel predictions for the scaling form of one-point correlation functions. A (necessary) virtue of the proposed approach is that it encodes and allows to naturally retrieve the purely geometric content of two-dimensional boundary conformal field theory. From the critical magnetization profile in presence of boundaries one can extract the scaling dimension of the order parameter, $Δ_ϕ$. For the 3D Ising model we find $Δ_ϕ=0.518142(8)$ which favorably compares (at the fifth decimal place) with the state-of-the-art estimate. A nontrivial prediction is the structure of two-point correlators at criticality. They should depend on the fractional Q-hyperbolic distance calculated from the metric, in turn depending only on the shape of the bounded domain and on $Δ_ϕ$. Numerical simulations of the 3D Ising model on a slab geometry are found to be in agreement with such predictions.

description: Asymmetric energy exchange interactions, also known as Hatano-Nelson type couplings, enable the study of non-Hermitian physics and associated phenomena like the non-Hermitian skin effect and exceptional points (EP). Since these interactions are by definition non-reciprocal, there have been very few options for real-space implementations in integrated photonics. In this work, we show that real-space asymmetric couplings are readily achievable in integrated photonic systems through time-domain dynamic modulation. We experimentally study this concept using a two-resonator photonic molecule produced in a lithium niobate on insulator platform that is electro-optically modulated by rf stimuli. We demonstrate the dynamic tuning of the Hatano-Nelson coupling between the resonators, surpassing the asymmetry that has been achieved in previous work, to reach an EP for the first time. We are additionally able to flip the relative sign of the couplings for opposite directions by going past the EP. Using this capability, we show that the through-chain transport can be configured to exhibit both giant (60 dB) optical contrast as well as photonic gyration or non-reciprocal pi phase contrast.

description: In the context of D-dimensional Euclidean gravity, we define the natural generalisation to D-dimensions of the self-dual Yang-Mills equations, as duality conditions on the curvature 2-form of a Riemannian manifold. Solutions to these self-duality equations are provided by manifolds of SU(2), SU(3), G_2 and Spin(7) holonomy. The equations in eight dimensions are a master set for those in lower dimensions. By considering gauge fields propagating on these self-dual manifolds and embedding the spin connection in the gauge connection, solutions to the D-dimensional equations for self-dual Yang-Mills fields are found. We show that the Yang-Mills action on such manifolds is topologically bounded from below, with the bound saturated precisely when the Yang-Mills field is self-dual. These results have a natural interpretation in supersymmetric string theory.

description: Recent developments and widespread in wireless sensor network have led to many routing protocols, many of these protocols consider the efficiency of energy as the ultimate factor to maximize the WSN lifetime. The quality of Service (QoS) requirements for different applications of wireless sensor networks has posed additional challenges. Imaging and data transmission needs both QoS aware routing and energy to ensure the efficient use of sensors. In this paper, we propose an Efficient, Energy-Aware, Least Cost, (ECQSR) quality of service routing protocol for sensor networks which can run efficiently with best-effort traffic processing. The protocol aims to maximize the lifetime of the network out of balancing energy consumption across multiple nodes, by using the concept of service differentiation, finding lower cost by finding the shortest path using nearest neighbor algorithm (NN), also put certain constraints on the delay of the path for real-time data from where link cost that captures energy nodes reserve, energy of the transmission, error rate and other parameters. The results show that the proposed protocol improves the network lifetime and low power consumption.

Electronic and optical properties of titanate-based oxide heterostructures

Publisher: name: Columbia University
Year: 2014
Subjects: Physics

description: In this thesis we study properties of transition metal oxide heterostructures and superlattices, including electronic structures, optical responses, and metal-insulator transitions.
      We start with a general discussion of the properties of transition metal oxides, primarily ABO₃ (A: rare earth ion, B: transition metal, O:oxygen) perovskites. We introduce the effect of A-site substitution on the electronic and magnetic properties in bulk perovskites, followed by the basic properties of oxide heterostructures and superlattices composed of two different ABO₃ perovskites focusing on the metal insulator transitions and properties of the interface electron gas.
      Next, we present calculations of the charge density profile, subband occupancy and ellipsometry spectra of the electron gas at the LaAlO₃/SrTiO₃ interface. The calculations employ self-consistent Hartree and random phase approximations. We discuss the dependence of spatial structure and subband occupancy on the magnitude of the polarization charge at the interface and spatial structure of the dielectric constant. The response to applied AC electric fields is calculated and the results are presented in terms of the ellipsometry angles. Our results show a dip in the ellipsometry spectrum near the longitudinal optic phonon frequency of the SrTiO₃ and a peak at higher energy, which are related to the in-plane Drude response and the out-of-plane plasmon excitation, respectively. The relation of the features to the subband occupancies and the in-plane conductivities is given.
      We conclude with the study of thickness dependent metal-insulator transitions in superlattices composed of Mott insulating GdTiO₃ and band insulating SrTiO₃ using a first-principles GGA+U method. The structural and metal-insulator phase diagrams with respect to the number of unit cells, n, of SrTiO₃ and on-site correlation U are presented, showing that there are two different insulating phases for n>1 and n=1. For superlattices with n>1 the insulating phase involves both charge and orbital ordering with associated structures in Ti-O bond lengths but for n=1 superlattices, we find an insulating phase driven by orbital ordering within the quasi one-dimensional bonding bands across the SrO layer. The inconsistencies with experiment suggests the importance of the many-body correlations.

description: Form factors for local spin operators of the XXZ Heisenberg spin-1/2 finite chain are computed. Representation theory of Drinfel'd twists for the sl2 quantum affine algebra in finite dimensional modules is used to calculate scalar products of Bethe states (leading to Gaudin formula) and to solve the quantum inverse problem for local spin operators in the finite XXZ chain. Hence, we obtain the representation of the n-spin correlation functions in terms of expectation values(in ferromagnetic reference state) of the operator entries of the quantum monodromy matrix satisfying Yang-Baxter algebra. This leads to the direct calculation of the form factors of the XXZ Heisenberg spin-1/2 finite chain as determinants of usual functions of the parameters of the model. A two-point correlation function for adjacent sites is also derived using similar techniques.

description: En este texto se presentan y analizan algunas de las conceptualizaciones sobre las múltiples desigualdades en el pensamiento social latinoamericano en las décadas de los años sesenta y setenta del siglo XX. Estas ideas tienen una doble inserción: por un lado, están enraizadas en tradiciones académicas y en discusiones teórico- conceptuales; por el otro, tienen un fuerte anclaje en el propio movimiento de los actores y en la inserción sociopolítica de las y los propios/as analistas. En ese momento histórico, la preocupación de analistas y de gobernantes estaba centrada en la cuestión del “desarrollo”. En este marco, el texto presenta una cuestión específica que se inscribe en el campo de las ideas de la época: la manera en que las y los analistas de la época discutieron e interpretaron la interrelación entre lo que consideraban la dimensión central de las desigualdades sociales – las clases sociales – y otras dimensiones y clivajes sociales, fundamentalmente el género (Saffioti, Larguía), la “raza” (Fernandes) y la etnicidad (Stavenhagen)

description: The interest in two-dimensional materials and materials physics has grown dramatically over the past decade. The family of two-dimensional materials, which includes graphene, transition metal dichalcogenides, phosphorene, hexagonal boron nitride, etc., can be fabricated into atomically thin films since the intralayer bonding arises from their strong covalent character, while the interlayer interaction is mediated by weak van der Waals forces. Among them, molybdenum disulfide (MoS₂) has attracted much interest for its potential applications in opto-electronic and valleytronics devices. Previously, much of the experimental studies have concentrated on optical and transport measurements while neglecting direct experimental determination of the electronic structure of MoS₂, which is crucial to the full understanding of its distinctive properties. In particular, like other atomically thin materials, the interactions with substrate impact the surface structure and morphology of MoS₂, and as a result, its structural and physical properties can be affected.
      In this dissertation, the electronic structure and surface structure of MoS₂ are directly investigated using angle-resolved photoemission spectroscopy and cathode lens microscopy. Local-probe angle-resolved photoemission spectroscopy measurements of monolayer, bilayer, trilayer, and bulk MoS₂ directly demonstrate the indirect-to-direct bandgap transition due to quantum confinement as the MoS₂ thickness is decreased from multilayer to monolayer. The evolution of the interlayer coupling in this transition is also investigated using density functional theory calculations. Also, the thickness-dependent surface roughness is characterized using selected-area low energy electron diffraction (LEED) and the surface structural relaxation is investigated using LEED I-V measurements combined with dynamical LEED calculations. Finally, bandgap engineering is demonstrated via tuning of the interlayer interactions in van der Waals interfaces by twisting the relative orientation in bilayer-MoS₂ and graphene-MoS₂-heterostructure systems.

description: The need for efficient, cheap, and durable semiconductors for photovoltaic and optoelectronic applications has spurred a number of dramatic recent developments in semiconductor quantum physics. Aided by advanced synthetic and characterization techniques, the development of high-quality, nano-structured, tunable materials has resulted in the observation of many novel phenomena. The goal of this thesis is to develop and apply methods in theoretical condensed matter science to the study of these promising materials.
      In Chapter 1 I explore methylammonium lead iodide (MAPbI3), a paradigmatic hybrid organic-inorganic perovskite system. To explain charge carrier dynamics in this material, I develop a microscopic tight-binding model. The average band structure is calculated and the magnitude of the temperature-dependent band gap opening and Urbach energy is quantified. The charge carrier mobility is calculated within a linear response formalism and its temperature dependence is characterized. Overall, the fully ab initio model is found to explain several non-trivial experimental phenomena while making minimal assumptions concerning the nature of the electron-phonon coupling and the character of the nuclear motion in these materials.
      In Chapters 2 and 3, I turn to the subject of atomically-thin transition metal dichalcogenides. I improve upon past variational calculations of exciton and trion binding energies in these materials by applying diffusion Monte Carlo to exactly calculate exciton, trion, and biexciton binding energies within an effective few-body Hamiltonian. Carriers are assumed to experience two-body interactions of the Keldysh type that have been parameterized previously from electronic structure calculations. The structures of the exact ground state wavefunctions are calculated and compared to those of the previous variational trial wavefunctions. Next, I calculate the doping dependence of the rate of exciton and trion elastic scattering with free electrons within first-order time-dependent perturbation theory. The calculation provides the first theoretical estimate of the intrinsic trion linewidth in these materials.
      Finally, in Chapter 4, I study variants of the GW approximation to the one-particle Green's function for calculating correlation energies and spectral weights for the three-dimensional homogeneous electron gas. By relating the cumulant generating function to the improper GW self-energy, I develop a new cumulant-based GW approximation. The approach is compared to existing methods first via solution of a simple linearly-coupled electron phonon model and later through application to the electron gas problem.

description: In recent years, several close post-common-envelope eclipsing binaries have been found to show cyclic eclipse timing variations (ETVs). This effect is usually interpreted either as the gravitational interaction among circumbinary bodies and the host binary -- known as the light travel time (LTT) effect -- or as the quadrupole moment variations in one magnetic active component -- known as Applegate mechanism. In this study, we present an analysis of the ETV and the magnetic cycle of the close binary KIC 10544976. This system is composed of a white dwarf and a red dwarf in a short orbital period (0.35 days) and was monitored by ground-based telescopes between 2005 and 2017 and by the Kepler satellite between 2009 and 2013. Using the Kepler data, we derived the magnetic cycle of the red dwarf by two ways: the rate and energy of flares and the variability due to spots. Both methods resulted in a cycle of ~600 days, which is in agreement with magnetic cycles measured for single low-mass stars. The orbital period of KIC 10544976 shows only one long-term variation which can be fitted by an LTT effect with period of ~16.8 yr. Hence, one possible explanation for the ETVs is the presence of a circumbinary body with minimal mass of ~13.4 M_Jup. In the particular scenario of coplanarity between the external body and the inner binary, the third body mass is also ~13.4 M_Jup. In this case, the circumbinary planet must either have survived the evolution of the host binary or have been formed as a consequence of its evolution.

 Records from India. ANDHRA PRADESH: Kadapa (= Cuddapah), Visakhapatnam— Naidu (1962), Rao & Mohan (1987); GENERAL RECORD: Naidu & Rao (2004), Purushothaman (2017).
 Habitat (as in Indian records). Freshwater; among filamentous algae.
 Distribution. Originally described from Austria, the species has been found later on throughout Europe, in north America and in India.
 Remarks. The species has been reported to be highly variable in size, with the total length ranging from 90 to 190 μm. Zelinka (1889) originally indicated a total length of 95-145 μm. The specimens first recorded from India by Naidu (1962) measured 80-100 μm in total length, so ranking among the smallest of its kind. Future analysis based on molecular data should confirm or disprove the taxonomic status of disjunct populations, especially the American and Indian forms of this species.

description: In this paper we present an explicit (rank one) function transform which contains several Jacobi-type function transforms and Hankel-type transforms as degenerate cases. The kernel of the transform, which is given explicitly in terms of basic hypergeometric series, thus generalizes the Jacobi function as well as the Bessel function. The kernel is named the Askey-Wilson function, since it provides an analytical continuation of the Askey-Wilson polynomial in its degree. In this paper we establish the $L^2$-theory of the Askey-Wilson function transform, and we explicitely determine its inversion formula.

description: Trotz ähnlicher Ausgangsbedingungen bestehen zwischen den postsozialistischen neuen Mitgliedsstaaten, die im Zuge der beiden Osterweiterungsrunden 2004 und 2007 der EU beitraten, signifikante Unterschiede hinsichtlich der Implementierung von EU-Gemeinschaftsrecht. In dieser Arbeit werden die Ursachen für (non-)compliance mit EU-Recht während der postaccession period durch Anwendung der drei Theorieansätze enforcement, anagement und legitimacy untersucht. Die Ergebnisse der empirischen Analyse zeigen, dass olitische Macht und die Unterstützung euroskeptischer Parteien Einfluss auf das compliance- Verhalten der neuen Mitgliedsstaaten haben. Administrative Effizienz lässt sich hingegen erst nach einem Vergleich der postsozialistischen Länder mit den Staaten der Süderweiterung als ursächlich für (non-)compliance festlegen, während wirtschaftliche Macht durch Einbeziehen der südeuropäischen Mitgliedsstaaten an Erklärungskraft verliert.
A conjectural generating function for numbers of curves on surfaces

description: I give a conjectural generating function for the numbers of $δ$-nodal curves in a linear system of dimension $δ$ on an algebraic surface. It reproduces the results of Vainsencher for the case $δ\le 6$ and Kleiman-Piene for the case $δ\le 8$. The numbers of curves are expressed in terms of five universal power series, three of which I give explicitly as quasimodular forms. This gives in particular the numbers of curves of arbitrary genus on a K3 surface and an abelian surface in terms of quasimodular forms, generalizing the formula of Yau-Zaslow for rational curves on K3 surfaces. The coefficients of the other two power series can be determined by comparing with the recursive formulas of Caporaso-Harris for the Severi degrees in $¶_2$. We verify the conjecture for genus 2 curves on an abelian surface. We also discuss a link of this problem with Hilbert schemes of points.
