description: We calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. The novel aspect of our calculations is that they are carried out to second order in the lattice spacing, O(a^2). We employ the Wilson/clover action for massless fermions (also applicable for the twisted mass action in the chiral limit) and the Symanzik improved action for gluons. Our calculations have been carried out in a general covariant gauge. Results have been obtained for several popular choices of values for the Symanzik coefficients (Plaquette, Tree-level Symanzik, Iwasaki, TILW and DBW2 action). We pay particular attention to $ΔF=2$ operators, both Parity Conserving and Parity Violating ($F$ stands for flavour: S, C, B). We study the mixing pattern of these operators, to O(a^2), using the appropriate projectors. Our results for the corresponding renormalization matrices are given as a function of a large number of parameters: coupling constant, clover parameter, number of colors, lattice spacing, external momentum and gauge parameter. The O(a^2) correction terms (along with our previous O(a^2) calculation of $Z_Ψ$) are essential ingredients for minimizing the lattice artifacts which are present in non-perturbative evaluations of renormalization constants with the RI'-MOM method. A longer write-up of this work, including non-perturbative results, is in preparation together with members of the ETM Collaboration.

description: In this work, we present (hemi)spherical atomic force microscopy (AFM) sensors for the detection of hydrogen peroxide. Platinum-black (Pt-B) was electrodeposited onto conductive colloidal AFM probes or directly at recessed microelectrodes located at the end of a tipless cantilever, resulting in electrocatalytically active cantilever-based sensors that have a small geometric area but, due to the porosity of the films, exhibit a large electroactive surface area. Focused ion beam-scanning electron microscopy tomography revealed the porous 3D structure of the deposited Pt-B. Given the accurate positioning capability of AFM, these probes are suitable for local in situ sensing of hydrogen peroxide and at the same time can be used for (electrochemical) force spectroscopy measurements. Detection limits for hydrogen peroxide in the nanomolar range (LOD = 68 ± 7 nM) were obtained. Stability test and first in situ proof-of-principle experiments to achieve the electrochemical imaging of hydrogen peroxide generated at a microelectrode and at photocatalytically active structured poly(heptazine imide) films are demonstrated. Force spectroscopic data of the photocatalyst films were recorded in ambient conditions, in solution, and by applying a potential, which demonstrates the versatility of these novel Pt-B-modified spherical AFM probes.
Investigations of cataract genetics
Creators: name: Burdon, Kathryn Penelope
Publisher: name: University Of Tasmania

description: Familial cataract is a heterogeneous disorder, characterised by opacity of the lens from an early age, often leading to blindness or severe visual disability. Approximately 20% of congenital cataracts are inherited and can occur in isolation or as part of over 200 genetic disorders. Many inherited cataracts also have an age of onset during childhood and as such are not truly congenital, but have similar aetiologies. There have been fourteen genes identified for isolated familial cataract, but many of the molecular causes remain unknown. Forty-five pedigrees with various forms of familial cataract have been collected from south-eastern Australia. This collection includes 40 with autosomal inheritance, four with X-linked inheritance and one with Nance-Horan Syndrome (NHS), an X-linked syndrome involving congenital cataract, dental abnormalities and mental retardation. Linkage studies of the large pedigree with Nance-Horan Syndrome lead to the refinement of the critical region for this disorder to 1.3 Mb through informative recombination events. Coding regions of all six characterised genes in the region were screened for mutations and shown not to be involved. A novel candidate gene was identified in the draft human genome sequence using gene prediction programs, EST information and comparison with other genomes available in public databases, and the genomic structure of the gene was determined experimentally. The gene was subsequently found to be expressed in all human tissues examined, including tissues affected by NHS such as eye and brain. Additional NHS pedigrees were ascertained and mutations of this novel gene were identified by direct sequencing in five of the six NHS pedigrees. All mutations caused severe truncation of the predicted protein and were not identified in controls. Hence, this novel gene, although its function remains unknown, is believed to be causative for Nance-Horan Syndrome. Analysis of known cataract genes and loci by both linkage analysis and mutation detection techniques in pedigrees with autosomal dominant congenital cataract revealed three mutations in previously known cataract genes. These mutations segregate with the cataract phenotype and are thought to be responsible for the cataract observed in these pedigrees. In addition, linkage analysis in one large pedigree has excluded linkage to most known loci, providing evidence for the existence of an additional locus for isolated congenital cataract. In summary, the molecular defect was determined in three large pedigrees with isolated autosomal dominant congenital cataract, and a novel gene was identified and shown to cause Nance-Horan Syndrome.

description: This proof-of-principle study presents the ability of the recently developed iLovEnose to measure ultratrace levels of volatile organic compounds (VOCs) in simulated human breath based on the combination of multiple gas sensors. The iLovEnose was developed by our research team as a test bed for gas sensors that can be hosted in three serially connected compact low-volume and temperature-controlled compartments. Herein, the eNose system was equipped with conventional semiconducting metal oxide (MOX) gas sensors using a variety of base technologies providing 11 different sensor signals that were evaluated to determine six VOCs of interest at eight low to ultralow concentration levels (i.e., ranging from 3 to 0.075 ppm) at humid conditions (90% rh at 22 °C). The measurements were randomized and performed four times over a period of 2 weeks. Partial least-squares regression analysis was applied to estimate the concentration of these six analytes. It was shown that the iLovEnose system is able to discriminate between these VOCs and provide reliable quantitative information relevant for future applications in exhaled breath analysis as a diagnostic disease detection or monitoring device.

description: We consider a class of ordinary differential equations describing one-dimensional quasiperiodically forced systems in the presence of large damping. We give a fully constructive proof of the existence of response solutions, that is quasi-periodic solutions which have the same frequency vector as the forcing. This requires dealing with a degenerate implicit function equation: we prove that the latter has a unique solution, which can be explicitly determined. As a by-product we obtain an explicit estimate of the minimal size of the damping coefficient.

Immune-regulatory genes in amoebic gill disease : potential for immunomodulation
Creators: name: Bridle, Andrew Roderick
Publisher: name: University Of Tasmania
Year: 2023

description: Amoebic Gill Disease (AGD) is the most significant health problem affecting Atlantic salmon, Salmo salar, culture in Tasmania, Australia. Caused by the ectoparasite Neoparamoeba sp., AGD is an emerging disease in several other countries (USA, Ireland, France, Spain, Chile, New Zealand) and affects several other cultured fish species (rainbow trout, Oncorhynchus mykiss, coho salmon, Oncorhynchus kisutch, turbot, Scophthalmus maximus). AGD and the cost of treatment, freshwater bathing, have negatively impacted on the production of Atlantic salmon in Tasmania. Consequently, alternative AGD management strategies are required. Thus an understanding of the disease processes associated with AOD pathology and the immune response to AGD is essential to the development of alternative AGD management strategies. Therefore, the immune response to AGD was partially characterised using molecular techniques, and the potential use of immunostimulants to reduce the impact of AGD on the Tasmanian salmonid industry was assessed. The transcriptional profile of selected immune-regulatory genes in the gill, liver and anterior kidney of experimentally infected Atlantic salmon and rainbow trout was assessed using semi-quantitative RT-PCR and quantitative real-time RT-PCR. Atlantic salmon interleukin-10 (IL-1)3) was shown to be up-regulated in the gills at 14 d post-inoculation (p.i.). In rainbow trout the expression of IL-1(3 and inducible nitric oxide synthase (iNOS) mRNA was significantly up-regulated in the gills at both 7 and 14 d p.i., while interleukin-8 was significantly up-regulated in the liverof AGD-affected trout at 7 d p.i. mRNA transcripts were localised by in situ hybridisation to pavement epithelial cells lining the primary and secondary lamellae of AGD-affected and control Atlantic salmon gills. These data demonstrated the involvement of the immune response to AGD at the molecular level and indicated the significance of the response at the site of infection. Intraperitoneal administration of immunostimulatory CpG oligodeoxynucleotides increased the resistance of Atlantic salmon to AGD. However, oral administration of 0-glucans, a well-known and potentially more cost-effective immunostimulant, was unable to enhance resistance to AGD. Nonetheless, a group of Atlantic salmon were able to survive an experimental AGD challenge. These findings allowed a preliminary AGD infection model to be proposed, and further our knowledge of the fish immune response to parasitic infection. The implications of this research show the potential for an effective immunological-based AGD management strategy such as use of a vaccine, immunostimulants or a selective breeding program.

Coherence and pairing in a doped Mott insulator: Application to the cuprates

description: The issues of single particle coherence and its interplay with singlet pairing are studied within the slave boson gauge theory of a doped Mott insulator. Prior work by one of us (T. Senthil, arXiv:0804.1555) showed that the coherence scale below which Landau quasiparticles emerge is parametrically lower than that identified in the slave boson mean field theory. Here we study the resulting new non-fermi liquid intermediate temperature regime characterized by a single particle scattering rate that is linear in temperature ($T$). In the presence of a d-wave pair amplitude this leads to a pseudogap state with $T$ dependent Fermi arcs near the nodal direction. Implications for understanding the cuprates are discussed.

Nonextensive quantum method for itinerant-electron ferromagnetism: Fractorization approach

description: Magnetic and thermodynamical properties of itinerant-electron (metallic) ferromagnets described by the Hubbard model have been discussed with the use of the generalized Fermi-Dirac (GFD) distribution for nonextensive quantum systems. We have derived the GFD distribution within the superstatistics, which is equivalent to that obtained by the maximum-entropy method to the Tsallis entropy with the factorization approimation. By using the Hartree-Fock approximation to the electron-electron interaction in the Hubbard model, we have calculated magnetic moment, energy, specific heat and Curie-Weiss-type spin susceptibility, as functions of the temperature and entropic index $q$ expressing the degree of the nonextensivity: $q=1.0$ corresponds to the Boltzmann-Gibbs statistics. It has been shown that with increasing the nonextensivity of $| q-1 |$, the temperature dependence of magnetic moment becomes more significant and the low-temperature electronic specific heat is much increased. This is attributed to enlarged Stoner excitations in the GFD distribution, which is elucidated by an analysis with the use of the generalized Sommerfeld expansion. We discuss the difference and similarity between the effects of the nonextensivity on metallic and insulating ferromagnets.

description: Spin chains have been proposed as quantum wires for information transfer in solid state quantum architectures. We show that huge gains in both transfer speed and fidelity are possible using a minimalist control approach that relies only a single, local, on-off switch actuator. Effective switching time sequences can be determined using optimization techniques for both ideal and disordered chains. Simulations suggest that effective optimization is possible even in the absence of accurate models.

description: Shapes of planar lipid monolayer domains at the air-water interface are theoretically and numerically investigated by minimizing the formation energy of the domains which consist of the surface energy, line tension energy, and dipole electrostatic energy. The shape equation which describes boundary curves of the domains at equilibrium state is derived from the first order variation of the formation energy. A relaxation method is proposed to find the numerical solutions of the shape equation. The theoretical and numerical results are in good agreement with previous experimental observation. Some new shapes not observed in previous experiments are also obtained, which awaits experimental confirmation in the future.

Black brane entropy and hydrodynamics: the boost-invariant case

description: The framework of slowly evolving horizons is generalized to the case of black branes in asymptotically anti-de Sitter spaces in arbitrary dimensions. The results are used to analyze the behavior of both event and apparent horizons in the gravity dual to boost-invariant flow. These considerations are motivated by the fact that at second order in the gradient expansion the hydrodynamic entropy current in the dual Yang-Mills theory appears to contain an ambiguity. This ambiguity, in the case of boost-invariant flow, is linked with a similar freedom on the gravity side. This leads to a phenomenological definition of the entropy of black branes. Some insights on fluid/gravity duality and the definition of entropy in a time-dependent setting are elucidated.

description: We present results obtained from extensive near-infrared spectroscopic and photometric observations of nova V574 Pup during its 2004 outburst. The observations were obtained over four months, starting from 2004 November 25 (four days after the nova outburst) to 2005 March 20. The near-IR JHK light curve is presented - no evidence is seen from it for dust formation to have occurred during our observations. In the early decline phase, the JHK spectra of the nova are dominated by emission lines of hydrogen Brackett and Paschen series, OI, CI and HeI. We also detect the fairly uncommon Fe II line at 1.6872 micron in the early part of our observations. The strengths of the HeI lines at 1.0830 micron and 2.0585 micron are found to become very strong towards the end of the observations indicating a progression towards higher excitation conditions in the nova ejecta. The width of the emission lines do not show any significant change during the course of our observations. The slope of the continuum spectrum was found to have a lambda^{-2.75} dependence in the early stages which gradually becomes flatter with time and changes to a free-free spectral dependence towards the later stages. Recombination analysis of the HI lines shows deviations from Case B conditions during the initial stages. However, towards the end of our observations, the line strengths are well simulated with case B model values with electron density n_e = 10^{9-10} cm^{-3} and a temperature equal to 10^4 K. Based on our distance estimate to the nova of 5.5 kpc and the observed free-free continuum emission in the later part of the observations, we estimate the ionized mass of the ejecta to be between 10^{-5} and 10^{-6} solar-mass.

The philosophy of comparative philosophy
Creators: name: Cook, BG
Publisher: name: University Of Tasmania
Year: 2023

description: Comparative philosophy is becoming an increasingly important method for understanding ourselves and those around us. At a time when the world's traditions and the great thinkers from the history of humanity are available at our fingertips like never before, comparative philosophy provides the tools to understand how humanity has differed between cultures and across time while simultaneously bringing to light those elements we have in common. While comparative philosophy is well established, its method has never been clearly outlined and comparative philosophers have relied on rusted and dull tools. The aim of this work is to outline a comparative methodology that overcomes the issues of relativity and objectivity, both of which threaten to undermine the comparative enterprise. Replacing these is perspectivism, the principles of which are outlined throughout this work, the only alternative that provides comparative philosophy with a set of tools suited specifically for its method of analysis. This work has a tiered structure with each chapter focusing on one aspect of the new methodology while resting on all that precedes it. The largest portion of this dissertation deals with the work of Nagarjuna and Nietzsche and, while the areas of comparison between these thinkers vary, it should be remembered that the structure of this work is set out to emphasise and aid in the understanding of the proposed method of comparative philosophy. With this method, comparative philosophy may proceed like never before, that is, with all the tools necessary to adequately fulfil its function.
Vortex-vortex interaction in thin superconducting films

Publisher: name: arXiv
Year: 2009
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The properties of vortices in superconducting thin films are revisited. The interaction between two Pearl vortices in an infinite film is approximated at all distances by a simple expression. The interaction of a vortex with a regular lattice of real or image vortices is given. The two spring constants are calculated that one vortex in the vortex lattice feels when the surrounding vortices are rigidly pinned or are free. The modification of these London results by the finite size of real films is obtained. In finite films, the interaction force between two vortices is not a central force but depends on both vortex positions, not only on their distance. At the film edges the interaction energy is zero and the interaction force is peaked. Even far from the edges the vortex interaction considerably deviates from the Pearl result and is always smaller than it.

To identify alien or potentially harmful fouling hydroid species in a marine aquaculture facility in Taranto (Italy), a study on the succession of the assemblages of these organisms was conducted on 36 panels immersed in April 2013 next to a fish cage. Three panels were analyzed for each combination of depth (0.2 m, 3 m, and 6 m) and immersion time (3, 6, 9, and 12 months); the hydrozoans growing on the surface of each panel were identified and their surface was estimated and analyzed with multivariate techniques. Species richness, frequency and biomass increased with time, paralleling the overall increase in structural complexity of the fouling assemblages. Medusa production was observed from locally abundant colonies of some species, potentially representing a nuisance for cultured fish through contact-driven envenomations and gill disorders. Several species were observed growing in epibiosis on alien invertebrates. The implications of these findings are discussed in light of the intense traffic of ships in the Port of Taranto.

description: No abstracts are to be cited without prior reference to the author. Cod Gadus morhua, harp seals Pagophilus groenlandicus and common minke whales Balaenoptera acutorostrata are the most conspicuous apex predators in the Barents Sea ecosystem. They mainly feed on fish and crustaceans such as krill, amphipods and shrimp. A recent study, where the competition between NEA cod, minke whales and sea birds was studied, suggests that cod and minke whales have a significant diet overlap and that the overlap increases with changes in the abundance of herring and krill. Given that cod and minke whales share both habitat and prey with the harp seals during their most intensive feeding period (summer/autumn) it is highly likely that they compete for food.

description: No abstracts are to be cited without prior reference to the author. The short-beaked common dolphin (Delphinus delphis) is the most abundant small cetacean in the north eastern Atlantic and in some regions by-catch is considered to be unsustainable. To help inform conservation measures, population models are needed to explore how the population will react under different scenarios. In order to build a population model, mortality-at-age curves derived from stranding data were constructed, using a Siler model fitted to the total observed dataset. Due to the paucity of data for the youngest age classes, a separate model was fit to a subset of the data that did not include the youngest age classes. Finally, a Heligman-Pollard model was fitted to the second subset of data as well, taking into account the proportion of by-caught dolphins in the sample. The survivorship curves for the Siler models reported that a median of 30% of the females achieve maturity when we used the total observed data set but only the 18% if we remove the youngest ages. The Heligman-Pollard model showed a more realistic shape since by-catch mortality was taken into account. The results of this model show an effective growth of 0.912 which indicate a population decline, likely due to high rates of by-catch.

description: No abstracts are to be cited without prior reference to the author. As it is known that in the Barents Sea hit content of sea surface layers beginning from 2000 to present can be defined as high and anomaly high level particularly in last 7 years. This caused of marine mammals great changes distribution, numbers and species structure here. In carrying out of research increasing of marine mammals numbers and regions meeting who inhabit in the Barents Sea all year around was brought. Increasing of time presence for animals who observe here periodically was recorded here also. Under that in our opinion climate change greatly influence to marine mammals distribution, numbers and species structure in the Barents Sea, and it can influence also to fish stocks as top predators. This reason in the paper will be presented results which in annual joint RussianNorwegian ecosystem survey in the Barents Sea about marine mammals distribution, numbers and species structure by specialist from PINRO and Institute of Marine Research from Bergen (IMR) accordingly were got.

description: We propose a generalized feedback model and compressive sensing based opportunistic feedback schemes for feedback resource reduction in MIMO Broadcast Channels under the assumption that both uplink and downlink channels undergo block Rayleigh fading. Feedback resources are shared and are opportunistically accessed by users who are strong, i.e. users whose channel quality information is above a certain fixed threshold. Strong users send same feedback information on all shared channels. They are identified by the base station via compressive sensing. Both analog and digital feedbacks are considered. The proposed analog & digital opportunistic feedback schemes are shown to achieve the same sum-rate throughput as that achieved by dedicated feedback schemes, but with feedback channels growing only logarithmically with number of users. Moreover, there is also a reduction in the feedback load. In the analog feedback case, we show that the propose scheme reduces the feedback noise which eventually results in better throughput, whereas in the digital feedback case the proposed scheme in a noisy scenario achieves almost the throughput obtained in a noiseless dedicated feedback scenario. We also show that for a fixed given budget of feedback bits, there exist a trade-off between the number of shared channels and thresholds accuracy of the feedback SINR.

description: C points, that is isolated points of circular polarization in transverse fields of varying polarization, are classified morphologically into three distinct types, known as lemons, stars and monstars. These morphologies are interpreted here according to two natural parameters associated with the singularity, namely the anisotropy of the C point, and the polarization azimuth on the anisotropy axis. In addition to providing insight into singularity morphology, this observation applies to the densities of the various morphologies in isotropic random polarization speckle fields.

description: Upcoming ground and space based observatories such as the DES, the LSST, the JDEM concepts and the SKA, promise to dramatically increase the size of strong gravitational lens samples. A significant fraction of the systems are expected to be time delay lenses. Many of the existing lensing degeneracies become less of an issue with large samples since the distributions of a number of parameters are predictable, and can be incorporated into an analysis, thus helping to lessen the degeneracy. Assuming a mean galaxy density profile that does not evolve with redshift, a Lambda-CDM cosmology, and Gaussian distributions for bulk parameters describing the lens and source populations, we generate synthetic lens catalogues and examine the relationship between constraints on the Omega_m - Omega_Lambda plane and H_0 with increasing lens sample size. We find that, with sample sizes of ~400 time delay lenses, useful constraints can be obtained for Omega_m and Omega_Lambda with approximately similar levels of precision as from the best of other methods. In addition, sample sizes of ~100 time delay systems yield estimates of H_0 with errors of only a couple of percent, exceeding the level of precision from current best estimates such as the HST Key Project. We note that insufficient prior knowledge of the lens samples employed in the analysis, via under or overestimates in the mean values of the sample distributions, results in broadening of constraints. This highlights the need for sound prior knowledge of the sample before useful cosmological constraints can be obtained from large time delay samples (abridged).

Are galactic coronae thermally unstable?

description: A substantial fraction of the baryons of disk galaxies like the Milky Way is expected to reside in coronae of gas at the virial temperature. This is the only realistic reservoir of gas available to feed star formation in the disks. The way this feeding occurs depends crucially on whether galactic coronae can fragment into cool clouds via thermal instability. Here I summarize arguments suggesting that galactic coronae are not prone to thermal instability, and I briefly discuss the implications for galaxy-formation models and for the origin of the high-velocity clouds of the Milky Way.

title: The effect of immunogenetic variability on human health: bioinformatics investigations from different perspectives
Creators: name: Takeshita, LYC
Publisher: name: University of Liverpool Repository
Year: 2018

description: The high level of diversity exhibited by genes coding for molecules involved in the immune system are critically involved with several aspects of human health. The ability of the immune system to recognize foreign pathogens or abnormal cells, while tolerating itself is achieved through a balance of various components and receptors in the immune system. Individual genotypes of immune genes such as HLA and KIR fine-tune this balance. Variability in those genes lead to diversity in the response to foreign molecules, and can also lead to intolerance to self-molecules in the form of autoimmune responses. Several past studies have found HLA and KIR polymorphisms to be associated with susceptibility or protection to a range of diseases and hypersensitivity to drugs. HLA has also a major role in transplantation, where transplanted tissues need to be as similar as possible to avoid rejection. The work described in this thesis contributes towards the knowledge of immunogenetic implications in associations with diseases, transplantation and adverse reactions to drugs using different bioinformatics approaches. First, it provides bioinformatics resources for a better understanding of the impact of immunogenetic diversity on human health in the form of two public databases, alongside with insights obtained through the analysis of their contents. The KIR and Disease Database (KDDB), described in Chapter 2, stores disease associations with KIR genes expressed in natural killer cells. The data within KDDB has been analysed to uncover trends within studies, in terms of the sets of KIR genes associated with susceptibility to, or protection from, auto-immune diseases, infectious diseases, pregnancy complications and cancer. The HLA Epitope Frequency Database (EpFreq-DB), described in Chapter 3, stores population frequencies of HLA epitopes, which are structural units on the surface of HLA molecules that have been increasingly associated with improvements in transplantation matching. An analysis has been performed to demonstrate global differences in the carriage of particular epitopes, and the potential functional consequences of using epitope mapping, instead of the more traditional allele matching for transplantation scenarios. Lastly, it investigates the molecular mechanisms underlying the association HLA polymorphisms with severe hypersensitivity caused by the anti- retroviral drug nevirapine, using molecular docking approaches. Developments described in this thesis contribute to better understanding of the influence of immune variability in human health and provides necessary knowledge to advances in personalized medicine.

description: The paper contains a brief review of recent results on hidden symmetries in higher dimensional black hole spacetimes. We show how the existence of a principal CKY tensor (that is a closed conformal Killing-Yano 2-form) allows one to generate a `tower' of Killing-Yano and Killing tensors responsible for hidden symmetries. These symmetries imply complete integrability of geodesic equations and the complete separation of variables in the Hamilton-Jacobi, Klein-Gordon, Dirac and gravitational perturbation equations in the general Kerr-NUT-(A)dS metrics. Equations of the parallel transport of frames along geodesics in these spacetimes are also integrable.
