Abstract:

Solid state synthesis of layered, rotationally disordered intergrowths consisting of rock salt (MX) and hexagonal (TX2) constituents in various sequences [(MX)1+δ]m[TX2]n is carried out by developing structural and compositional prototypes of the desired product, using fine control of the elemental reactants and then annealing at low temperature to facilitate self-assembly. (M = Sn, La, Eu; T = V, Mo.) The remarkable rotational disorder in these systems - in contrast to traditional misfits - and their proven applications in thermal, electrical and thermoelectric disciplines make them a useful group of materials for demonstrating control of reaction pathways of solid state reactions using low temperatures and short times. The synthesized materials are structurally characterized using X-ray diffraction (XRD), X-ray reflectivity (XRR), and Scanning Transmission Electron Microscopy (STEM). Electrical characterization is carried out on patterned samples using the Van der Pauw method of resistivity and the Hall effect method. Composition of the samples is determined using wavelength dispersive electron probe microanalysis (EPMA). Time domain thermoreflectance is used to determine the cross plane thermal conductivity. The family of [(SnSe)1.05]m(MoSe2)n (m = n = 1, 2, 3, 4), which possess the same composition but different unit cell thicknesses, shows that there is no correlation between c-axis unit cell thickness and cross plane thermal conductivity. The family of structural isomers [(SnSe)1.05]4[MoSe2]4, [(SnSe)1.05]3[MoSe2]3[(SnSe)1.05]1[MoSe2]1, [(SnSe)1.05]3[MoSe2]2[(SnSe)1.05]1[MoSe2]2, [(SnSe)1.05]2[MoSe2]3[(SnSe)1.05]2[MoSe2]1,[(SnSe)1.05]2[MoSe2]1[(SnSe)1.05]1[MoSe2]2[(SnSe)1.05]1[MoSe2]1 and [(SnSe)1.05]2[MoSe2]2[(SnSe)1.05]1[MoSe2]1[(SnSe)1.05]1[MoSe2]1 have the same c-axis lattice thickness and absolute composition but have different numbers of [(SnSe)1.05]/[MoSe2] interfaces. Thermal conductivity studies carried out on these showed no correlation with the interface density. (LaSe1-x)1.17(VSe2-y)n (n = 2, 3, 4) feature a family of compounds that self-assemble at higher than usual temperatures. They form non-stoichiometric moieties with unique structural proclivities including La vacancies and V interstitials compared to other ferecrystals or previous misfits. The designable electrical properties show evidence of charge transfer. (EuSe)1+δ(VSe2)n (n = 1, 2, 3) is a family of materials that complements the investigation of Ln-based ferecrystals. They show evidence of multiple M oxidation states. These compounds highlight the use of rational design of structure and composition to tune properties. This dissertation includes previously published and unpublished co-authored material.

Abstract:

In this thesis, we study certain non-perturbative aspects of N=1 gauge theories. We show how to compute the expectation values of chiral operators (i.e. those that preserve the anti-chiral supercharges) exactly from a first-principle approach based on the path integral over the microscopic fields.

The text is divided into two parts. The first one consists of an original introduction to the tools that underlie the researches and results obtained during this thesis. After a general introduction, we present some methods to obtain exact results. Covered topics include instantons, N=2 supersymmetry and localization,N=1 supersymmetry and holomorphy, and finally the Dijgraaf-Vafa matrix model formalism and the perturbative generalized Konishi anomaly equations. These preliminaries were chosen to enlighten the presentation of our results. A brief overview of our results is then. This includes localization in some N=1 gauge theories, its applications to the computation of chiral correlators as well as a non-perturbative discussion of the generalized Konishi equations and of the Dijkgraaf-Vafa glueball superpotential. We insist on the ideas and the results, postponing the details for the second part, which consists of a faithful reproduction of the papers published during this thesis and in which the author has been involved. /

Dans cette thèse, nous étudions certains aspects non-perturbatifs des théories de jauge supersymétriques N=1. Plus précisemment, nous montrons comment les valeurs moyennes des opérateurs chiraux (qui préservent la moitié des supercharges) dans les vides quantiques peuvent être calculées sans approximations, à partir d'une approche basée sur l'intégrale fonctionnelle sur les champs microscopiques.

Ce mémoire est divisé en deux parties. La première consiste en une introduction à l'approche microscopique des théories de jauge supersymétriques. Une grande fraction de celle-ci est dédiée à la présentation des concepts et méthodes qui sont à la base du développement de ce formalisme et de nos recherches. Ceci inclut les instantons, la supersymétrie N=2 et la localisation dans l'intégrale fonctionnelle, la supersymétrie N=1 et l'holomorphie, et enfin l'approche de Dijkgraaf-Vafa basée sur un modèle de matrices et les équations d'anomalie généralisées de Konishi. Ensuite, nous présentons le formalisme microscopique et les résultats obtenus durant cette thèse. Nous expliquons comment utiliser la technique de localisation dans certaines théories de jauge N=1 et comment l'appliquer au calcul des valeurs moyennes des opérateurs chiraux. Nous discutons également de façon non-perturbative les équations d'anomalie généralisées de Konishi et le superpotentiel de Dijkgraaf-Vafa. La plupart des résultats exacts connus dans les théories de jauge N=1 sont reproduits, dont la condensation des gluinos et la brisure de la symétrie chirale.

Nous insistons sur les idées et les résultats plutôt que sur les détails techniques. Ceux-ci sont décrits dans la seconde partie de ce mémoire, qui consiste en une reproduction fidèle des travaux publiés durant cette thèse.

Abstract:

The main focus of this thesis is to study the physical characteristics of the N-terminus of human XAF1 protein, a 17kD protein named NTA1, by biophysical methods. Structural studies of the N-terminus of XAF1 serves as a base for the studies of the structure and function relationship of the N-terminus, and the same maybe true for the full length XAF1. Bioinformatics analysis shows that NTA1 shares high sequence identity with the TRAF-type zinc finger domain-containing protein 1 (TRAFD1) and FLN29. Protein structure prediction has been performed on NTA1 by the I-TASSER web server. The prediction result suggests that NTA1 is a structure that consists of α-helices which are joined by flexible linkers. The loose structure shown by I-TASSER is expected to have high solvent accessibility. This coincides with the deuterium exchange data. In addition, by the CD approach, NTA1 was estimated to contain high α-helix content. This result is consistent with the bioinformatics prediction and the secondary structure obtained from the chemical shift index method as well. The physical characterizations of NTA1 showed that NTA1 is a loosely packed protein; and the five zinc ions are bound in the protein structure. Based on the chemical shifts of β-carbons, the Cysteine residues Cys8, Cys11, Cys34, Cys37, Cys50, Cys59, Cys62, Cys86, Cys89 and Cys115 showed a significantly downfield shift, they are probably involved in the zinc ions coordination. The dynamic property of NTA1 was investigated by NMR techniques. Backbone dynamics of NTA1 reveal that NTA1 does not have a typical spherical structure, it is anisotropic. Residues corresponding to the zinc finger regions in the predicted structure show large R2/R1 and S2 values, while regions shown to be flexible linkers in the 3D structure prediction show small R2/R1 and S2 values. Thus, the protein structure homology modeling data are supported by the backbone dynamics data.

Abstract:

Preview benefits (PBs) from two words to the right of the fixated one (i.e., word N+2)and associated parafoveal-on-foveal effects are critical for proposals of distributed lexical processing during reading. This experiment examined parafoveal processing during reading of Chinese sentences, using a boundary manipulation of N+2-word preview with low- and high-frequency words N+1. The main findings were (a) an identity PB for word N+2 that was (b) primarily observed when word N+1 was of high frequency (i.e., an interaction between frequency of word N+1 and PB for word N+2), and (c) a parafoveal-on-foveal frequency effect of word N+1 for fixation durations on word N. We discuss implications for theories of serial attention shifts and parallel distributed processing of words during reading.

Abstract:

Let X be the affine flag manifold of Lie type A_{n-1}^(1) where n ≥ 3 and let W_{aff} be the associated affine Weyl group. The moment graph for X encodes the torus fixed points (which are elements of the affine Weyl group W_{aff} and the torus stable curves in X. Given a fixed point u ∈ Waff and a degree d = (d_0, d_1, ..., d_{n−1}) ∈ Z^{n≥0}, the combinatorial curve neighborhood is the set of maximal elements in the moment graph of X which can be reached from u′ ≤ u by a chain of curves of total degree ≤ d. In this thesis we give combinatorial formulas and algorithms for calculating these elements.
Doctor of Philosophy
The study of curves on flag manifolds is motivated by questions in enumerative geometry and physics. To a space of curves and incidence conditions one can associate a combinatorial object called the ‘combinatorial curve neighborhood’. For a fixed degree d and a (Schubert) cycle, the curve neighborhood consists of the set of all elements in the Weyl group which can be reached from the given cycle by a path of fixed degree in the moment graph of the flag manifold, and are also Bruhat maximal with respect to this property. For finite dimensional flag manifolds, a description of the curve neighborhoods helped answer questions related to the quantum cohomology and quantum K theory rings, and ultimately about enumerative geometry of the flag manifolds. In this thesis we study the situation of the affine flag manifolds, which are infinite dimensional. We obtain explicit combinatorial formulas and recursions which characterize the curve neighborhoods for flag manifolds of affine Lie type A. Among the conclusions, we mention that, unlike in the finite dimensional case, the curve neighborhoods have more than one component, although all components have the same length. In general, calculations reflect a close connection between the curve neighborhoods and the Lie combinatorics of the affine root system, especially the imaginary roots.

Abstract:

Thesis (MScEng (Process Engineering))--Stellenbosch University, 2008.
Developments in the field of liquid detergents and cosmetics have increased the demand for surfactants, processing aids and emollients. Alcohols are often used in liquid products where they serve as solvents for the detergent ingredients, adjust the viscosity and prevent product separation. Industrial scale oxygenation of the alkane to the alcohol is often incomplete, resulting in a significant amount of residual alkane. Application of these alcohols often requires a low residual alkane content and a post-production separation process is thus required. Traditional separation methods such as distillation and crystallisation are not technically viable as crossover melting and boiling points prevent the successful implementation of such processes and it is envisaged to use supercritical extraction to separate a mixture of n-alkanes and 1- alcohols. The project scope revolves around a product stream consisting of detergent range alcohols and corresponding n-alkanes that need to be separated. To model such a system, a typical detergent range alkane – alcohol feed with an average of 13 carbon atoms was selected, although a large number of the molecules have between 12 and 14 carbon atoms each. Generally the presence of the hydroxyl group as well as an increase in the number of carbon atoms decreases the solubility in supercritical solvents [17]-[19]. The most difficult separation will therefore be that of the alcohol with the least number of carbon atoms, that is 1-dodecanol (alcohol with 12 carbon atoms, CH3-(CH2)9-CH2-OH ) and the alkane with the most number of carbon atoms, that is n-tetradecane (alkane with 14 carbon atoms, CH3-(CH2)12-CH3 ). To model the system, it is assumed that the hydrocarbon backbone is linear and the alcohol is primary. Therefore 1-dodecanol and n-tetradecane are used. If it is possible to separate 1-dodecanol and ntetradecane with the use of supercritical fluids, it should be possible to separate an industrial mixture. The deliverables of this study are: a comparison of the high pressure solubility of n-tetradecane and 1-dodecanol with a selection of possible solvents; a selection of potential solvents to be tested on a pilot plant to confirm practical separation. From the literature and measured phase equilibria, all three solvents (carbon dioxide, ethane and propane) have the ability to distinguish (based on a difference in the pressure required for solubility) between 1-dodecanol and n-tetradecane. Both carbon dioxide and ethane have favourable temperature considerations. Propane has superior solubility of n-tetradecane and 1- dodecanol. Carbon dioxide demonstrates the highest selectivity. Pilot plant experiments have shown that both carbon dioxide and ethane have the ability to separate a 50-50% (mass percentage) mixture of 1-dodecanol and n-tetradecane. Both solvents perform at their best at low temperatures. Carbon dioxide shows the best results at low temperature and conditions of reflux. The highlight of pilot plant experiments with supercritical carbon dioxide is achieving a selectivity of 16.4 with the mass percentage of n-tetradecane at 5% and 82% for the bottoms and overheads product respectively. Very good separation is achieved using supercritical ethane as solvent even without reflux. Attention is drawn to pilot plant experiments where the selectivity is as high as 82 with the mass percentage of n-tetradecane in the bottoms and overheads product at 1% and 82% respectively. It is recommended to measure ternary phase equilibria for the system n-tetradecane, 1-dodecanol and carbon dioxide/ethane to establish the interaction between n-tetradecane and 1-dodecanol. The measured binary phase equilibrium data need to be expanded to include the vapour mass fraction composition in the isothermal solubility data.

Abstract:

The drug, N,N bis (ethylene)-P (1-adamantyl) phosphonic diamide inhibits focus formation of Rous Sarcoma Virus in tissue culture. Transformation of chick cells was inhibited when the drug was added to chick cells prior to infection. The drug did not inhibit the transformation of Normal Rat Kidney Cells infected with RSV, when the cells were grown at non-permissive temperatures and shifted to permissive temperatures upon addition of the drug. Nor did the drug revert cells transformed at permissive temperatures. These studies indicated that the inhibition of RSV is in the early stage of viral growth, possible penetration or uncoating.

Abstract:

Orbital degrees of freedom play vital role in prompting novel phenomena in ruthenium based Ruddlesden-Popper compounds through coupling of orbits to spin and lattice. Physical properties are then particularly susceptible to small perturbations by external magnetic fields and/or slight structural changes. Current study pertains to the impact when a more-extended 4d Ruthenium ion is replaced by a less-extended 3d Chromium ion. Perovskite CaRuO3 (n=∞) is characterized by borderline magnetism and non- Fermi liquid behavior – common occurrences in quantum critical compounds. Remarkably, Cr substitution as low as x=0.05 abruptly drives CaRu1−xCrxO3 from a paramagnetic state to an itinerant ferromagnetic state (MS~0.4μB/f.u.), where TC=123K for x=0.22. The Cr-driven magnetism is highly anisotropic suggesting an important role of spin-orbit coupling. Unlike other chemical substitutions in the compound, Cr does not induce any Metal-Insulator transition that is expected to accompany the magnetic transition. The results indicate a coupling of Ru-4d and Cr-3d electrons that is unexpectedly favorable for itinerant ferromagnetism, which often exists delicately in the ruthenates. Bilayered Ca3Ru2O7 (n=2), an abode of huge anisotropy, exhibits a wide range of physical properties – Colossal Magnetoresistance occurring only when the spin polarized state is avoided, Antiferromagnetic-Metallic (AFM-M) state, Quantum Oscillations (periodic in 1/B and in B) that are highly angular dependent, to mention a few. Experimental results obtained so far provide a coherent picture illustrating that orbital order and its coupling to lattice and spin degrees of freedom drive the exotic electronic and magnetic properties in this Mott-like system. Transport and thermodynamic studies on Ca3(Ru1-xCrx)2O7 (0 ≤ x ≤ 0.20) reveal that AFM-M region is broadened with x that ultimately reaches 70K for x=0.20 (~8K for x=0). In this region, electron transport is enhanced and inhibited when B is applied along crystal’s respective axes, confirming an intrinsic half-metallic behavior. Moreover, the difference in coercivities of Ru and Cr magnetic ions pave way for the first-ever observation of a strong spin-valve effect in bulk material, a quantum phenomenon so far realized only in multilayer thin films or heterostructures. This discovery opens new avenues to understand the underlying physics of spin-valves and fully realize its potential in practical devices.

Abstract:

The methylation at the α-N-terminal amines of proteins that start with a canonical motif X-P-K (X=A/P/S) has been a known modification for nearly four decades. In 2010, protein α-N-terminal methyltransferase 1 (NTMT1/NRMT1) was identified as the first enzyme responsible for this modification. NTMT2 was discovered as a second member belonging to this family, but it was reported as a mono-methylase. The identification of RCC1, retinoblastoma (Rb) protein, centromere protein-A/B (CENP-A/B), and DNA damaged-binding protein 2 (DDB2) as new NTMT1 substrates revealed NTMT1’s biological significance in mitosis, cell-cycle regulation, centromere formation, and damaged DNA repair, respectively. Although significant progress had been made, a clear understanding of how NTMT1 recognizes substrates remains to be determined. Also, there is no specific small molecule inhibitor for NTMT1. To fill these gaps, we first established a fluorescence-based assay for kinetic characterization of NTMT1. Subsequently, ternary complex crystal structures of NTMT1 were obtained to illustrate the structural basis for enzyme-substrate interactions. The structures of the enzyme-substrate complex coupled with mutagenesis, binding, and enzymatic studies demonstrated the key elements involved in interaction with its substrates. In the meantime, we utilized computational studies and fluorescence assays for novel small molecule discovery. Lastly, we closely monitored the substrates’ methylation progression by NTMT1 and NTMT2 in parallel using a MALDI-MS based assay. Our results indicated that NTMT1 follows a Bi-Bi mechanism, and its methylation proceeds in a distributive pattern. Furthermore, NTMT1 was identified has broad substrate specificity beyond its canonical motif X-P-K (X=A/P/S), since X can be any amino acid except D/E and the third amino acids can also be R. We had also discovered an inhibitor that targets the substrate binding site of NTMT1 with IC50 = 7 µM. Lastly, our methylation progression studies has demonstrated that NTMT2 can also di-, tri-methylate certain substrates although its methylation rate is lower than NTMT1. Overall, this project has laid the foundation for further investigation of N-terminal methylation in terms of functions, mechanisms, and inhibitor design.

Abstract:

In this work, we study the time evolution of systems containing a large number of particles interacting via a $1/r$ binary interaction potential, such as Coulombian and self-gravitating systems. In particular, we study the effect on the dynamics of the Holtsmark-Chandrasekhar theory, which describes the static fluctuations of the total force field around the Vlasov mean-field. We derive these effects by developing a new perturbative theory using the fundamental representation of Statistical Mechanics :The BBGKY hierarchy. This leads to a modification of the Vlasov equation by an additional term involving a fractional Laplacian to the power $3/4$ in velocity space, and a fractional iterated time integral of order $1/2$. We show that one of the consequences of this new term for spatially homogeneous systems is the appearance in the velocity distribution of long tails in $v^{-5/2}$. By extension, similar behaviors can be expected for weakly inhomogeneous systems. These long tails correspond to a universal mechanism related to the divergence of the interaction potential in $1/r$. More specifically, they are induced by the long tails of the total force field distribution as described by the Holtsmark-Chandrasekhar theory. Such a result cannot be obtained from theories based on the weak-coupling between particles, which lead to the Vlasov term, and, the Landau collision operator at the next order. We verify numerically these results by means of molecular dynamics simulations. We study the evolution of the velocity distributions for times very short compared to the violent relaxation time. In this particular time regime, we find, as expected, power laws in $v^{alpha}$ for the velocity distribution tail. In particular, when the regularization parameter of the interaction potential tends to $0$, the exponent in the power law indeed tends from below toward the theoretically predicted value $alpha=-5/2$.

Abstract:

The HIV-1 surface glycoprotein, gp120, is made of a rapidly mutating protein core and an extensive carbohydrate shield which are, respectively, encoded by the viral genome and synthesised by the host cell. In contrast to host cell glycoproteins however, gp120 contains a population of unprocessed oligomannose-type glycans that interact with host lectins, promote HIV infection, and alter cell signalling. They also form the basis of the epitopes of several broadly neutralising antibodies isolated against HIV, making them a key feature for immunogen design. The mechanistic basis of how HIV glycans are differentially processed by the host cell was demonstrated on a recombinant gp120 model, suggesting that steric occlusion within the patch of densely packed glycans lead to lack of processing by ER and Golgi α-mannosidases. Furthermore, an elevated level of oligomannose-type glycans was evidenced on gp120 isolated from HIV-1_JRCSF virions produced in PBMCs, compared to recombinant material (respectively ~79% and ~29% of total N-linked glycans), along with a subset of highly processed and sialylated, bi-, tri- and tetra-antennary complex-type glycans, which could be involved in direct interaction with key host cell immune receptors and strongly suppress both antibody and T-cell immune responses. The effect of variation in viral production systems was analysed, with envelope glycoprotein derived from pseudoviral particles produced in HEK 293T cells exhibiting predominantly an oligomannose population (98%), compared to gp120 isolated from a single-plasmid infectious molecular clone (56%). Finally, mutation of one or several glycosylation site(s), known to be required for oligomannose-restricted neutralizing antibodies, was shown to induce a subtle redistribution within the oligomannose series whilst maintaining overall oligomannose levels. The gp120 glycan profile is therefore robust to mutations and also remarkably similar across primary viral isolates from Africa, Asia and Europe and consequently represents an attractive target for vaccine development.

Abstract:

The present paper examines the N₁ by N₁ construction using corpus linguistic methodology.The distribution of types of the construction that occur more than once either unhyphenated or hyphenated in any subcorpus of the British National Corpus accessed through the BrighamYoung University interface is examined. Written and spoken language as well as variousgenres are compared. Hyphenation is also investigated. A collocation analysis of some typesof the construction is further carried out and it is concluded that the N₁ by N₁ construction canbe part of the on a N₁ by N₁ basis construction. Results from the quantitative analysis as wellas the qualitative discussion suggest that the N P N construction may be undergoinglexicalisation starting as an adverbial and moving to functioning as a premodifier. Thissuggestion is indicated through complementary diachronic searches in the Oxford EnglishDictionary. It is also indicated that the construction may follow a development pattern similarto that of N₁to N₁. The notion of construction is discussed in relation to the N₁ by N₁ construction, and a hierarchical view of constructions is proposed as a solution to some of theproblems with the term.

Abstract:

In the presented work, first principle studies on electronic structure, stability, and magnetic properties of metal chalcogenide, CrnTem clusters have been carried out within a density functional framework using generalized gradient functions to incorporate the exchange and correlation effects. The energetic and electronic stability was investigated, and it was found that they are not always correlated as seen in the cluster Cr6Te8 which has smaller gap between its HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital) and a high electron affinity of 3.39 eV indicating lower electronic stability whereas higher fragmentation energy indicating energetic stability. The high electron affinity shows that the stability of Cr6Te8 cluster can be enhanced by adding charge donating ligands including PEt3 to form stable Cr6Te8(PEt3)6 clusters as seen in experiments. The other cluster of interest was Cr4Te6 in which energetic stability was accompanied with electronic inertness marked by its large HOMO-LUMO gap, non-magnetic ground state and high fragmentation energy.

Abstract:

A 13C and 6Li variable temperature NMR study of 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates formed from reacting 2-ethyl-1-butanol with 2-ethylbutyllithium in two O/Li ratios of 0.2/1 and 0.8/1. The 0.2/1 sample resulted in two 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates and seven lithium hydride/lithium 2-ethyl-1-butoxide mixed aggregates. The lithium hydride mixed aggregates were also studied using selective 1H decoupling experiments. The 0.8/1 sample resulted in six 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates and five lithium hydride/lithium 2-ethyl-1-butoxide mixed aggregates. A low temperature 13C NMR spectroscopy study of n-pentyllithium indicated three aggregates, most likely a hexamer, an octamer, and a nonamer. A low temperature 13C NMR study of an 0.2/1 O/Li ratio sample of n-pentyllithium mixed with 1-pentanol resulted in three n-pentyllithium/lithium n-pentoxide aggregates mixed aggregates along with the three n-pentyllithium aggregates. 13C NMR data for this mixture gave inconclusive results whether or not lithium hydride/lithium alkoxide mixed aggregates were present in the sample.

Abstract:

Stochastic processes are used to study the dynamics of evolution in finite, structured populations. Simulations of such processes provide a useful tool for their study, but are currently limited by computational speed and memory bottlenecks, even when naively parallelized. This thesis proposes two novel parallelization methods for simulating a particular class of evolutionary processes known as "games on graphs." The theoretical speed-up and scalability of these methods is analyzed across various parameters. A novel approximate parallel method is also proposed, which allows for further speed-up at the expense of some accuracy. Discussion of implementation considerations follows, and a resulting implementation in Python is used to provide empirical performance results which match closely with theoretical ones. Applications are suggested for a variety of open problems in biology, behavioral economics, political science, and linguistics.
