possession
possessive constructions

description: This thesis studies possession in Lelepa, a language from the Oceanic subgroup of Austronesian, spoken in Central Vanuatu. Investigating this particular feature of the language was achieved by collecting original data from Lelepa speakers. Language data is presented in the form of interlinearised examples taken from a corpus of texts and elicitation notes. Data was collected between 2006 and 2008 during fieldtrips to Lelepa and Mangaliliu. The core of the study is devoted to the possessive system of Lelepa. Like many other Oceanic languages, Lelepa has direct and indirect possessive constructions. This thesis shows that the direct possessive construction formally consists of a possessed noun to which a possessor suffix attaches. It encodes possession of semantic domains such as body parts, body products, reference kinship terms, items closely associated to the possessor and parts of wholes. Indirect possession is expressed by two distinct subtypes: the free and construct indirect constructions. The free indirect construction has pronominal possessors only, encoded by two distinct pronoun paradigms: general and part-whole possession pronouns. The former pronouns are used for possession of items that normally do not occur in the direct construction, and the latter are used for possession of parts of wholes. The construct indirect construction is characterised by the occurrence of either of two construct suffixes, -n or -g. The -n construct indirect construction has pronominal and nominal possessors, and the same semantic scope as the direct construction. The -g construct indirect construction has nominal possessors only, and the same semantic scope as the free indirect construction with general possession pronouns. This study also demonstrates that free variation between two possessive constructions, the direct construction and the -n construct indirect construction with pronominal possessors, occur in the language, although more work is needed to determine the scope of this feature.

description: We propose periodic Macdonald processes as a $(q,t)$-deformation of periodic Schur processes and a periodic analogue of Macdonald processes. It is known that, in the theory of stochastic processes related to a family of symmetric functions, the Cauchy-like identity gives an explicit expression of a partition function. We compute the partition functions of periodic Macdonald processes relying on the free field realization of the Macdonald theory. We also study several families of observables for periodic Macdonald processes and give formulas of their moments. The technical tool is the free field realization of operators that are diagonalized by the Macdonald symmetric functions, where the operators admit expressions by means of vertex operators. We show that, when we adopt Plancherel specializations, the corresponding periodic Macdonald process is related to a Young diagram-valued periodic continuous process. It is known that, for periodic Schur processes, determinantal formulas are only available when we extend them to take into account the charge. We also consider this kind of shift-mixed periodic Macdonald processes and discuss their Schur-limit.

Studies Toward the Total Synthesis of Panduratin and Bicuculline Natural Products
Creators: name: Pasfield, Luke
Publisher: name: The Australian National University
Year: 2021

description: Please see file attached under "Table of Contents". This thesis describes the total synthesis of racemic panduratin A (8), 4-hydroxypanduratin A (9), nicolaioidesin B (20) (isopanduratin A), 4-hydroxyisopanduratin A (36), panduratin H (17), panduratin I (18) and studies towards synthesis of bicuculline (166). The synthesis of the panduratin family members was achieved after first performing a model synthesis to successfully develop the required synthetic methodology. This involved a Diels-Alder reaction between cinnamaldehyde (48) and butadiene (42) followed by the addition of an organolithium derived from a bromobenzene. This developed methodology allowed the generation of many panduratin analogues as well as several panduratin family members. Some of the analogues were tested against the dengue fever serotype 2 (DEN-2) protease along with 4-hydroxypanduratin A (9). In addition to the synthesis of the panduratin family members and analogues, a regioselectivity study of high pressure Diels-Alder reactions between various cinnamates and E-ocimene (31) was also conducted to elucidate the steric and electronic factors responsible for the regioselectivity. Following this study modified dienes with strong directing groups were synthesised in an attempt to shift the product distribution towards Diels-Alder product where the prenyl group was ortho to the electron withdrawing group of the cinnamate. With respect to the synthesis of bicuculline (166) two approaches were employed. The first approach involved synthesis of a biaryl Z-alkene that could then undergo an intra-molecular tethered aminohydroxylation to afford the core of bicuculline. Biaryl alkene (245) was successfully synthesised through a Sonogashira coupling and subsequent reduction of the alkyne. Studies towards the remaining transformations remain ongoing. The second approach to bicuculline (166) used a Suzuki coupling between MIDA boronate 259 and aryl iodide 230. The trans-alkene 229 was then converted to the epoxide followed by deprotection of the amine to facilitate a ring closure resulting in a crude sample that has been postulated to be bicuculline (166). Investigations into alternative ring closure conditions and purification strategies are ongoing.
Condensation of Tubular D2-branes in Magnetic Field Background

description: It is known that in the Minkowski vacuum a bunch of IIA superstrings with D0-branes can be blown-up to a supersymmetric tubular D2-brane, which is supported against collapse by the angular momentum generated by crossed electric and magnetic Born-Infeld (BI) fields. In this paper we show how the multiple, smaller tubes with relative angular momentum could condense to a single, larger tube to stabilize the system. Such a phenomena could also be shown in the systems under the Melvin magnetic tube or uniform magnetic field background. However, depending on the magnitude of field strength, a tube in the uniform magnetic field background may split into multiple, smaller tubes with relative angular momentum to stabilize the system.

description: Exploiting hyperentanglement of photon pairs, that is, simultaneous entanglement in multiple degrees of freedom(DOFs), increases the dimensionality of Hilbert spaces for quantum information processing. However, generation of hyperentangled photon pairs collinearlly, while produces high brightness, results in a smaller Hilbert space due to the two photons being in the same spatial mode. In this letter, we point out that one can recover the full dimensionality of such hyperentanglement through a simple interference set up, similar to the time-reversed Hong-Ou-Mandel (TR-HOM) process. Different from the standard TR-HOM, we point out a critical phase condition has to be satisfied in order to recover the hyperentanglement. We theoretically analyze the realization of this approach and discuss the feasibility of generating truly hyperentangled photon pairs. Our proposed approach does not require post-selection and hence enables efficient hyper-entangled photon pairs generation for high-dimensional quantum applications.

description: Com o intuito de atender uma demanda interna e externa crescente, a produção de soja tem se expandido. Nos estados do centro-oeste, observa-se que produtores possuem áreas de terra maiores e produzem em maior escala. A evolução dos dados dos censos agropecuários brasileiros mostra uma tendência de redução do número de pequenos estabelecimentos produtores de soja na região sul. Justifica-se assim o objetivo desse estudo de determinar o tamanho ótimo da atividade de produção de soja, a fim de inferir sobre a existência de economias de escala no setor. O referencial teórico é o da teoria da dualidade da função custo e de produção. Os dados foram obtidos através de uma pesquisa de campo, em uma amostra de duzentos e dezoito produtores de soja nos cinco principais estados produtores. As estimativas de economias de escala obtidas apontam uma escala ótima de produção de aproximadamente 9.000 toneladas de soja, que pode ser obtida em propriedades com aproximadamente 3.000 hectares de área de produção de soja. Os resultados sugerem que as economias de escala estejam determinando uma nova configuração para o setor de produção de soja no Brasil.

description: In my first chapter I have given an account of the origins and development of servant types before the seventeenth century. This introductory study makes no pretense of being exhaustive. The comedy servant in the first half of the seventeenth century has been treated in somewhat fuller manner in the second chapter, especially from Pierre Corneille on. The principal subject of this study, however, is the development of servant types from the time of Moliere to that of Lesage, and here I believe I have been as thorough as reasonably possible. Where it was necessary, I have used the resources of a number of libraries, and some plays have been filmed. For information about certain rare plays I have had to depend on secondary sources. The monumental work of Dr. H. C. Lancaster, completed since I began work on this topic, has of course been invaluable in checking the completeness of my coverage as well as for general reference

description: Histone deacetylase 6 (HDAC6) was a potential target for Alzheimer’s disease (AD). In this study, a series of novel oxyevodiamine-based HDAC6 inhibitors with a variety of linker moieties were designed, synthesized and evaluated. Compound 12 with a benzyl linker was identified as a high potent and selective HDAC6 inhibitor. It inhibited HDAC6 with an IC50 value of 6.2 nM and was more than 200 fold selectivity over HDAC1. It also had lower cytotoxicity and higher anti-H2O2 activity in vitro comparing with other derivatives. Compound 12 might be a good lead as novel HDAC6 inhibitor for the treatment of AD.

description: Three new prenylated C6–C3 compounds (1–3), together with two known prenylated C6–C3 compounds (4–5) and one known C6–C3 derivative (6), were isolated from the roots of Illicium brevistylum A. C. Smith. The structures of 1–3 were elucidated by spectroscopic methods including 1D and 2D NMR, HRESIMS, CD experiments and ECD calculations. The structure of illibrefunone A (1) was confirmed by single-crystal X-ray diffraction analysis. All compounds were evaluated in terms of their anti-inflammatory potential on nitric oxide (NO) generation in lipopolysaccharide-stimulated murine RAW264.7 macrophages and murine BV2 microglial cells, antiviral activity against Coxsackievirus B3 (CVB3) and influenza virus A/Hanfang/359/95 (H3N2). Compounds 3 and 4 exhibited potent inhibitory effects on the production of NO in RAW 264.7 cells with IC50 values of 20.57 and 12.87 μM respectively, which were greater than those of dexamethasone (positive control). Compounds 1 and 4–6 exhibited weak activity against Coxsackievirus B3, with IC50 values ranging from 25.87 to 33.33 μM.

description: The classical alternating current optimal power flow problem is highly nonconvex and generally hard to solve. Convex relaxations, in particular semidefinite, second-order cone, convex quadratic, and linear relaxations, have recently attracted significant interest. The semidefinite relaxation is the strongest among them and is exact for many cases. However, the computational efficiency for solving large-scale semidefinite optimization is lower than for second-order cone optimization. We propose a conic relaxation obtained by combining semidefinite optimization with the reformulation-linearization technique, commonly known as RLT. The proposed relaxation is stronger than the second-order cone relaxation and nearly as tight as the standard semidefinite relaxation. Computational experiments using standard test cases with up to 6515 buses show that the time to solve the new conic relaxation is up to one order of magnitude lower than for the chordal relaxation, a semidefinite relaxation technique that exploits the sparsity of power networks.

Simulated payments under 1976 program parameters and stochastic yields are estimated at $300 million, compared with actual payments of $522 million in 1974 and $262 million in 1975. A payment greater than $522 million will probably not occur again under current conditions. The $262 million level is closer to normal expectations. The model also evaluates the impact of revisions in the payment program, as well as the effect of uncertain crop yields.

description: The valence-quark distribution function of the pion has been of interest for decades; particularly, the profile it should adopt when $x\to1$ (the large-$x$ behavior) is subject of a long-standing debate. In the light-front holographic QCD (LFHQCD) approach, this behavior is controlled by the so called reparametrization function, $w_τ(x)$, which is not fully determined from first principles. We show that, owing to the flexibility of $w_τ(x)$, the large-$x$ profile $u^π(x)\sim (1-x)^{2}$ can be contained within the LFHQCD formalism. This is in contrast with a previous LFHQCD study~(Guy F. de Teramond et al., Phys. Rev. Lett., 120(18), 2018) in which $u^π(x)\sim (1-x)^{1}$ is found instead. Given our observations, augmented by perturbative QCD and recent lattice QCD results, we state that the large-$x$ exponent of "2" cannot be excluded.

description: Costs of seven methods of handling beef by retail firms are explored, considering number and size of stores per firm and distance from the packer. The least costly method is centralized cutting into retail cuts by retail firms. Larger store size reduced per unit costs significantly for all systems studied, while number of stores per firm affected costs only slightly.

description: The specific angular momentum of Cold Dark Matter (CDM) halos in a $Λ$CDM universe is investigated. Their dimensionless specific angular momentum $λ'=\frac{j}{\sqrt{2}V_{vir} R{vir}}$ with $V_{vir}$ and $R_{vir}$ the virial velocity and virial radius, respectively depends strongly on their merging histories. We investigate a set of $Λ$CDM simulations and explore the specific angular momentum content of halos formed through various merging histories. Halos with a quiet merging history, dominated by minor mergers and accretion until the present epoch, acquire by tidal torques on average only 2% to 3% of the angular momentum required for their rotational support ($λ'=0.02$). This is in conflict with observational data for a sample of late-type bulgeless galaxies which indicates that those galaxies reside in dark halos with exceptionally high values of $λ' \approx 0.06-0.07$. Minor mergers and accretion preserve or slowly increase the specific angular momentum of dark halos with time. This mechanism is however not efficient enough in order to explain the observed spin values for late-type dwarf galaxies. Energetic feedback processes have been invoked to solve the problem that gas loses a large fraction of its specific angular momentum during infall. Under the assumption that dark halos hosting bulgeless galaxies acquire their mass via quiescent accretion, our results indicate yet another serious problem: the specific angular momentum gained during the formation of these objects is not large enough to explain their observed rotational properties,even if no angular momentum would be lost during gas infall.

An Analytical Process of Spatial Autocorrelation Functions Based on Moran's Index

description: A number of spatial statistic measurements such as Moran's I and Geary's C can be used for spatial autocorrelation analysis. Spatial autocorrelation modeling proceeded from the 1-dimension autocorrelation of time series analysis, with time lag replaced by spatial weights so that the autocorrelation functions degenerated to autocorrelation coefficients. This paper develops 2-dimensional spatial autocorrelation functions based on the Moran index using the relative staircase function as a weight function to yield a spatial weight matrix with a displacement parameter. The displacement bears analogy with time lag of time series analysis. Based on the spatial displacement parameter, two types of spatial autocorrelation functions are constructed for 2-dimensional spatial analysis. Then the partial spatial autocorrelation functions are derived by Yule-Walker recursive equation. The spatial autocorrelation functions are generalized to the autocorrelation functions based on Geary's coefficient and Getis' index. As an example, the new analytical framework was applied to the spatial autocorrelation modeling of Chinese cities. A conclusion can be reached that it is an effective method to build an autocorrelation function based on the relative step function. The spatial autocorrelation functions can be employed to reveal deep geographical information and perform spatial dynamic analysis, and lay the foundation for the scaling analysis of spatial correlation.

description: Similarities between alkali gases in optical lattices with non-integer occupation of the lattice sites and quantum crystals are explored. The analogy with the vacancy liquid (VL) provides an alternative explanation to the Mott transition for the recent experiment on the phase transition in the lattice. The VL can undergo BEC with T_{c} within experimental reach. Direct and vacancy-assisted mechanisms of the band motion for hyperfine impurities are discussed. Large concentration of vacancies can result in the spatial decomposition of the system into pure hyperfine components. Below the vacancy condensation the impurity component resembles 3He in 3He-HeII mixtures.

description: Multiple initial state parton interactions in p(d)+Au collisions are calculated in a Glauber-Eikonal formalism. The convolution of perturbative QCD parton-nucleon cross sections predicts naturally the competing pattern of low-pT suppression due geometrical shadowing, and a moderate-pT Cronin enhancement of hadron spectra. The formal equivalence to recent classical Yang-Mills calculations is demonstrated, but our approach is shown to be more general in the large x>0.01 domain because it automatically incorporates the finite kinematic constraints of both quark and gluon processes in the fragmentation regions, and accounts for the observed spectra in elementary pp-->π+X processes in the RHIC energy range, sqrt{s} = 20-200 GeV. The Glauber-Eikonal formalism can be used as a baseline to extract the magnitude of dynamical shadowing effects from the experimental data at differente centralities and pseudo-rapidities.

description: Technology creates changes in agriculture that all segments of the agricultural community need to consider to anticipate the resulting impacts. Objectives of the research were to project the size and number of farming operations in eastern Washington and to examine the implications for farm size of four-wheeldrive tractor technology. Based on Markov chain projections of farm size, enlargements will occur in farms over 1,000 acres. Use of four-wheel-drive tractors will pressure farming operations larger than 2,000 acres to enlarge further.

description: A continuous stroking sensation on the skin can convey messages or emotion cues. We seek to induce this sensation using a combination of illusory motion and lateral stroking via a haptic device. Our system provides discrete lateral skin-slip on the forearm with rotating tactors, which independently provide lateral skin-slip in a timed sequence. We vary the sensation by changing the angular velocity and delay between adjacent tactors, such that the apparent speed of the perceived stroke ranges from 2.5 to 48.2 cm/s. We investigated which actuation parameters create the most pleasant and continuous sensations through a user study with 16 participants. On average, the sensations were rated by participants as both continuous and pleasant. The most continuous and pleasant sensations were created by apparent speeds of 7.7 and 5.1 cm/s, respectively. We also investigated the effect of spacing between contact points on the pleasantness and continuity of the stroking sensation, and found that the users experience a pleasant and continuous linear sensation even when the space between contact points is relatively large (40 mm). Understanding how sequential discrete lateral skin-slip creates continuous linear sensations can influence the design and control of future wearable haptic devices.

description: We consider Einstein gravity with the addition of $R^2$ and $R^{μν} R_{μν}$ interactions in the context of effective field theory, and the corresponding scattering amplitudes of gravitons and minimally-coupled heavy scalars. First, we recover the known fact that graviton amplitudes are the same as in Einstein gravity. Then we show that all amplitudes with two heavy scalars and an arbitrary number of gravitons are also not affected by these interactions. We prove this by direct computations, using field redefinitions known from earlier applications in string theory, and with a combination of factorisation and power-counting arguments. Combined with unitarity, these results imply that, in an effective field theory approach, the Newtonian potential receives neither classical nor quantum corrections from terms quadratic in the curvature.

description: Membrane transport proteins (MTPs) transfer nutrients, metabolic products and inorganic ions across membranes. Many MTPs are essential for Plasmodium blood infection and gain importance as candidate drug targets in malaria therapy, whereas the physiological functions of many MTPs still remain enigmatic. In this thesis, we applied experimental genetics to determine key characteristics of four selected Plasmodium MTPs, including spatio-temporal expression and phenotypical analysis of knockout mutants. We employed the murine malaria model parasite Plasmodium berghei and in vitro blood cultures of the human malaria parasite Plasmodium falciparum. For this study, we selected one conserved MTP called FT2, which was previously shown to transport folate, a P-type ATPase that is specific for P. falciparum as well as two essential MTPs, CRT and ATP4, with important roles in anti-malarial therapy. These targets exemplify the range of druggable candidates and illustrate the potential and limitations of reverse genetics to decipher their physiological roles for Plasmodium life cycle progression. A combination of transgenic and knockout strategies was applied to the P. berghei folate transporter 2 (FT2). We show that endogenously tagged FT2 localises to the apicoplast membranes, and is broadly expressed throughout the parasite‚Äôs life cycle. Strikingly, in two stages, schizonts and sporozoites, FT2 displays a dual localisation. Analysis of FT2-deficient parasites revealed a severe sporulation defect in the vector; the vast majority of ft2‚Äì oocysts form large intracellular vesicles which displace the cytoplasm. Accordingly, very few sporozoites are generated and these are non-infectious to the mammalian host, resulting in a complete arrest of Plasmodium transmission. A candidate aminophospholipid P-type ATPase, that is encoded by human malaria parasites, but not P. berghei and related Vinckeia parasites, was assessed by a CRISPR/Cas9-mediated gene disruption. Compared to many vital P-type ATPases this gene is dispensable for asexual blood replication. Two MTPs, ATP4 and CRT are prime targets for antimalarial therapies. A comprehensive spatio-temporal expression analysis of transgenic parasites expressing mCherry tagged proteins revealed expression beyond blood infection, indicative of functions in additional parasite stages. Together, the findings of this study contribute towards a better understanding of the roles of the four MTPs based on localisation, expression and functional deletion.
