description: Die Arbeit befasst sich mit der Synthese und spektroskopischer Untersuchung platinmodifizierter Basenpaare bzw. Basentripel und der Untersuchung ihrer Selbst-erkennungseigenschaften unter Ausbildung von Wasserstoffbrücken sowie dem Einsatz dieser Komplexe als potentielle Rezeptormoleküle, die komplementäre Substrat- oder Anionen-moleküle über Wasserstoffbrücken reversibel binden können.Der wichtigste im Rahmen dieser Arbeit verwendete Ligand ist die Modellnukleobase 9-Methylhypoxanthin (9-MeHyp), die neben 9-Methylguanin (9-MeGH) zu den 6-Oxopurin-nukleobasen gehört. Ebenfalls eingesetzt wird die Purinnukleobase 9-Methyladenin (9-MeA) bzw. die Pyrimidinnukleobase 1-Methylcytosin (1-MeC).Im ersten Teil werden mononukleare Homo- bzw. Heteropurin sowie gemischte Purin-Pyrimidin Basenpaare mit der trans-a2Pt2+-Einheit (a=NH3 oder CH3NH2) beschrieben. Die Auswahl der Nukleobase bestimmt die H-Donor-/Akzeptorreihenfolge, so dass die Bildung metallmodifizierter Basenquartetts gebunden über Wasserstoffbrücken erfolgt. Reaktion der dargestellten Modellverbindungen mit Silber führt zu einem geschlossenen tetranuklearen Nukleobasenquartett bzw. einer polymeren Helix.Ausgehend von dem diplatinierten Adeninbaustein trans,trans-[(a2PtCl)2(µ-9-MeA-N7,N1)]2+ (a=NH3 oder CH3NH2) werden Basentripel mit 6-Oxopurinnukleobasen (9-Methyl-guanin und 9-Methylhypoxanthin) synthetisiert und charakterisiert. Untersucht wird dabei die Neigung der neutralen 6-Oxopurinnukleobasen in den Komplexen mit Transplatin Selbstassoziation über Wasserstoffbrücken einzugehen und große Aggregate wie Basen-sextetts oder Meander auszubilden.Der letzte Teil dieser Arbeit behandelt Versuche zum Nachweis der molekularen Erkennung über Wasserstoffbrücken zwischen den synthetisierten mono- bzw. dinuklearen Modellverbindungen und den komplementären Molekülen.

description: Background : The emergence of hyperon degrees of freedom in neutron star matter has been associated to first order phase transitions in some phenomenological models, but conclusions on the possible physical existence of an instability in the strangeness sector are strongly model dependent. Purpose : The purpose of the present study is to assess whether strangeness instabilities are related to specific values of the largely unconstrained hyperon interactions, and to study the effect of the strange meson couplings on phenomenological properties of neutron stars and supernova matter, once these latter are fixed to fulfill the constraints imposed by hypernuclear data. Method : We consider a phenomenological RMF model sufficiently simple to allow a complete exploration of the parameter space. Results : We show that no instability at supersaturation density exists for the RMF model, as long as the parameter space is constrained by basic physical requirements. This is at variance with a non-relativistic functional, with a functional behavior fitted through ab-initio calculations. Once the study is extended to include the full octet, we show that the parameter space allows reasonable radii for canonical neutron stars as well as massive stars above two-solar mass, together with an important strangeness content of the order of 30\%, slightly decreasing with increasing entropy, even in the absence of a strangeness driven phase transition. Conclusions : We conclude that the hyperon content of neutron stars and supernova matter cannot be established with present constraints, and is essentially governed by the unconstrained coupling to the strange isoscalar meson.

description: The COVID-19 pandemic has caused havoc around the globe since 2019 and is considered the largest global epidemic of the twentieth century. Although the first antiviral drug, Remdesivir, was initially introduced against COVID‑19, virtually no tangible therapeutic drugs exist to treat SARS-CoV-2 infection. FDA-approved Paxlovid (Nirmatrelvir supplemented by Ritonavir) was recently announced as a promising drug against the SARS-CoV-2 major protease (Mpro). Here we report for the first time the remarkable inhibitory potentials of lead epigenetic-targeting drugs (epi-drugs) against SARS-CoV-2 Mpro. Epi-drugs are promising compounds to be used in combination with cancer chemotherapeutics to regulate gene expression. The search for all known epi-drugs for the specific inhibition of SARS-CoV-2 Mpro was performed for the first time by consensus (three high-order program) molecular docking studies and end-state free energy calculations. Several epi-drugs were identified with highly comparable binding affinity to SARS-CoV-2 Mpro compared to Nirmatrelvir. In particular, potent histone methyltransferase inhibitor EPZ005687 and DNA methyltransferase inhibitor Guadecitabine were prominent as the most promising epi-drug inhibitors for SARS-CoV-2 Mpro. Long Molecular dynamics (MD) simulations (200 ns each) and corresponding MM-GBSA calculations confirmed the stability of the EPZ005687-Mpro complex with MM-GBSA binding free energy (ΔGbind) −48.2 kcal/mol (EPZ005687) compared to Nirmatrelvir (–44.7 kcal/mol). Taken together, the antiviral activities of the highlighted epi-drugs are reported beyond widespread use in combination with anti-cancer agents. The current findings therefore highlight as yet unexplored antiviral potential of epi-drugs suitable for use in patients struggling with chronic immunosuppressive disorders.

description: Chemiluminescent radiation of the vibrationally and rotationally excited OH radical, which dominates the nighttime near-infrared emission of the Earth's atmosphere in wide wavelength regions, is an important tracer of the chemical and dynamical state of the mesopause region between 80 and 100 km. As radiative lifetimes and rate coefficients for collision-related transitions depend on the OH energy level, line-dependent emission profiles are expected. However, except for some height differences for whole bands mostly revealed by satellite-based measurements, there is a lack of data for individual lines. We succeeded in deriving effective emission heights for 298 OH lines thanks to the joint observation of a strong quasi-2-day wave (Q2DW) in eight nights in 2017 with the medium-resolution spectrograph X-shooter at the Very Large Telescope at Cerro Paranal in Chile and the limb-sounding SABER radiometer on the TIMED satellite. Our fitting procedure revealed the most convincing results for a single wave with a period of about 44 h and a vertical wavelength of about 32 km. The line-dependent as well as altitude-resolved phases of the Q2DW then resulted in effective heights which differ by up to 8 km and tend to increase with increasing vibrational and rotational excitation. The measured dependence of emission heights and wave amplitudes (which were strongest after midnight) on the line parameters implies the presence of a cold thermalized and a hot non-thermalized population for each vibrational level.

description: We propose a new class of metastable dark energy (DE) phenomenological models in which the DE decay rate does not depend on external parameters such as the scale factor or the curvature of the Universe. Instead, the DE decay rate is assumed to be a constant depending only on intrinsic properties of DE and the type of a decay channel, similar to case of the radioactive decay of unstable particles and nuclei. As a consequence, the DE energy density becomes a function of the proper time elapsed since its formation, presumably in the very early Universe. Such a natural type of DE decay can profoundly affect the expansion history of the Universe and its age. Metastable DE can decay in three distinct ways: (i) exponentially, (ii) into dark matter, (iii) into dark radiation. Testing metastable DE models with observational data we find that the decay half-life must be many times larger than the age of the Universe. Models in which dark energy decays into dark matter lead to lower values of the Hubble parameter at large redshifts relative to $Λ$CDM. Consequently these models provide a better fit to cosmological BAO data (especially data from from high redshift quasars) than concordance ($Λ$CDM) cosmology.

Für die Bestimmung der eingesetzten und während der Experimente ge-bildeten Stick-stoffverbindungen wurden Analysenverfahren erarbeitet. Es wurde der Einfluß relevanter Parameter wie z.B. des pH-Wertes, der Art und Konzentration des Photokatalysators, der Struktur der Stickstoffverbindungen auf Abbauraten und Produktbildung bestimmt. Auf der Basis der Abbauversuche wurden mögliche Abbaumechanismen entwickelt. Desweiteren wurden im Rahmen dieser Arbeit die Einsatzmöglichkeiten dotierter und photoplatinierter TiO2 Photo-katalysa-toren studiert. Insbesondere der Einfluß der Dotierung auf die elektronische Struktur des Photo-katalysators wurde sowohl theoretisch als auch experimentell untersucht. Ferner wurden Studien zum Abbau von Stick-stoffver-bindungen mit immobilisierten Photokatalysatoren durchgeführt. Die erzeugten Schichten wurden mittels oberflächenanalytischer Methoden charakterisiert. Im Hinblick auf eine technische Anwendung wurde abschliessend die Kombination der Photokatalyse mit anderen Abwasser-reinigungsverfahren geprüft. Darüberhinaus konnte ein Weg für die Übertragung des Abbau-verfahrens auf reale Bedingungen anhand eines Upscalings und durch Abbauversuche an realen Proben aufgezeigt werden.
description: The possibilities of the photocatalytic degradation of aliphatic and aromatic N-compounds by TiO2 as photocatalyst has been investigated. Different analytical methods for the determination of the used N-Compounds and their breakdown products were developed. The influence of relevant parameters e.g. the pH-Value, kind and concentration of the photocatalyst, structure of the N-compounds on the degradation rates and distribution of the photooxidation products was determined. Based on the obtained results possible degradation mechanisms were developed. Furthermore, the photocatalytic properties of doped and photoplatinized TiO2-powders were studied. Especially the influence of the doping on the electronic structure of the photocatalyst was theoretically and experimentally examined. Moreover, the possibilities of mineralization of N-compounds under use of immobilized pure and doped TiO2-powders were studied. The generated TiO2-coatings were characterized by surface analytical methods. With regard to a technical application the combination of photocatalysis with other wastewater treatment methods was investigated. Beyond that the conclusions drawn from the degradation of model substances showed also to be valid for real waste water samples as experienced from a diluted, liquid bovine manure. An upscaling of the laboratory experiments to pilot-plant scale under use of real solar radiation was realized.

description: This talk is an outline of two closely-related projects to be based at Leiden University over the coming 24 months. Gorwaa (South-Cushitic, Afro-Asiatic), Hadza (isolate), and Ihanzu (Bantu (F-group), Niger-Congo) are three of the least documented languages of the Tanzanian Rift Valley linguistic area. Decreasing numbers (15,000 for Gorwaa in 2017, 650 for Hadza in 2013, and 32,000 for Ihanzu in 1987), environmental change, and the loss of linguistic domains to Swahili all contribute to the endangerment status of these three languages. Building on knowledge gained during previous documentation projects (Gorwaa for Andrew Harvey, and Asimjeeg Datooga for Richard Griscom), the current projects aim to provide equivalent documentation of materials deemed historically and culturally important for the Ihanzu and Hadza, including musical traditions, oral histories, and traditional ecological knowledge. Harvey will employ these materials, supplemented in all three languages with structured elicitation, to form the basis of grammatical analysis comparing specific features present in these languages with the characteristic areal features for the Tanzanian Rift Valley. Griscom, focusing exclusively on Hadza, will conduct detailed sociolinguistic interviews, as well as explore possible regional differences in varieties of Hadza. Both projects will actively involve the language communities by training local speakers in audiovisual language documentation methods, as well as providing funding for them to make extensive recordings of their own languages. This project is based on the assumption that language contact also implies human contact (intermarriage, cultural contact, etc.), and aims to challenge traditional assumptions of the African past as one in which ethnic groups were static, isolated, and primitive, and to suggest alternative African pasts in which African societies are dynamic, innovative, and often more complex than an ethicity-based view of ‘tribe’ allows. Furthermore, it aims to actively involve Africans in this reframing process and to provide a platform for the indigenous peoples of the Rift Valley Area to actively participate in and guide the documentation of their languages.

description: The long-standing problem of time in canonical quantum gravity is the source of several conceptual and technical issues. Here, recent mathematical results are used to provide a consistent algebraic formulation of dynamical symplectic reduction that avoids difficult requirements such as the computation of a complete set of Dirac observables or the construction of a physical Hilbert space. In addition, the new algebraic treatment makes it possible to implement a consistent realization of the gauge structure off the constraint surface. As a consequence, previously unrecognized consistency conditions are imposed on deparameterization -- the method traditionally used to unfreeze evolution in completely constrained systems. A detailed discussion of how the new formulation extends previous semiclassical results shows that an internal time degree of freedom need not be semiclassical in order to define a consistent quantum evolution.

Organotrifluoroborate salts

Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: New types of organotrifluoroborate (RBF3-) salts are described in this thesis, primarily made and studied for the purpose of applying them as electrolytes in electrochemical devices. Electrolytes are an important potential application of ionic liquids (ILs) since their properties are extremely attractive in this role. Their main disadvantage in this application is their typically high viscosity, which limits mass transport rates in the electrolyte media. However, the overall performance of an electrolyte is not solely dependant on the viscosity of the IL. Taking dye-sensitized solar cells (DSSCs) as a currently investigated IL application, overall efficiencies appear to also be dependent on the type of IL. Therefore, the new RBF3- salts were synthesized with the aim of producing salts that could potentially exhibit low viscosity liquids or good conductive solids. The salts were also characterised for their electrolyte properties and those with good potential were further studied with the redox couple triiodide/iodide for use in DSSCs. Tribology studies were carried out for a phosphonium-based RBF3- that showed relatively good potential as a lubricant. The salt also showed improved wear and maintained friction with an increased severity of test condition. The RBF3- ions were also tested for their hydrolytic stability, following a study that revealed the hydrolytic instability of the tetrafluoroborate ion (BF4-). The study involved the use of pH measurement as a primary detection of the anion decomposition in water, from which the by-product is hydrofluoric acid. The result is that the RBF3- ions proved to be more hydrolytically stable to BF4-.
Understanding pantothenate synthetase: mechanism, inhibition and monitoring of enzymatic reactions
Creators: name: Lee, Amanda Elizabeth
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The research described herein is directed towards understanding the enzyme pantothenate synthetase; including monitoring of the enzymatic reaction with fluorescent small-molecule chemosensors and the development of nucleoside-based enzyme inhibitors. Chapters 2 to 4 detail the design, synthesis and evaluation of fluorescent pyrophosphate chemosensors. In Chapter 2, a previously described naphthalene diimide chemosensor 50 was prepared and evaluated. The naphthalene diimide chemosensor 50 demonstrated good selectivity for pyrophosphate when compared with other biologically relevant anions. However, when evaluated in an enzymatic assay it was not sufficiently robust to be applied to real-time monitoring. Chapter 3 details the preparation of two novel anthracene-based chemosensors 61 and 62. These two anthracene-based chemosensors 61 and 62 utilised chelation enhanced fluorescence (CHEF) to generate a high fluorescent output. However, their utility was limited by a lack of selectivity, resulting in difficulties resolving pyrophosphate from structurally related adenosine mono phosphate, diphosphate and triphosphate (AMP, ADP, ATP). Chapter 4 describes the development of two novel core-substituted naphthalene diimide chemosensors 92 and 93, aiming to combine the good selectivity for PPi of the first generation NDI chemosensor with the excellent quantum yields of the second generation anthracene chemosensors. Chemosensors 92 and 93 demonstrated interesting photophysical properties. However, limited solubility in aqueous solution prevented their application to the monitoring of enzymatic reactions. Chapter 5 details the preparation, isolation and purification of the enzyme pantothenate sythetase from E. coli. Furthermore, work toward the preparation of nucleoside-based inhibitors of pantothante synthetase is also described. While the initial route to access the target compounds was unsuccessful, preliminary studies on a revised strategy addressed the shortcomings of the initial approach. Chapter 6 describes the subsequent application of anthracene-based chemosensors 61 and 62 to the detection of zinc in aqueous systems. Chemosensors 61 and 62 provided accurate detection of zinc at environmentally relevant concentrations in the presence of competing analytes. However, they were unable to detect any zinc present in real environmental samples.

description: Micro aerial vehicles (MAVs) are strongly limited in their payload and power capacity. In order to implement autonomous navigation, algorithms are therefore desirable that use sensory equipment that is as small, low-weight, and low-power consuming as possible. In this paper, we propose a method for autonomous MAV navigation and exploration using a low-cost consumer-grade quadrocopter equipped with a monocular camera. Our vision-based navigation system builds on LSD-SLAM which estimates the MAV trajectory and a semi-dense reconstruction of the environment in real-time. Since LSD-SLAM only determines depth at high gradient pixels, texture-less areas are not directly observed so that previous exploration methods that assume dense map information cannot directly be applied. We propose an obstacle mapping and exploration approach that takes the properties of our semi-dense monocular SLAM system into account. In experiments, we demonstrate our vision-based autonomous navigation and exploration system with a Parrot Bebop MAV.

description: Several experimental collaborations worldwide intend to test sterile neutrino models by measuring the disappearance of antineutrinos produced via isotope decay at rest (IsoDAR). The most advanced of these proposals have very similar setups, in which a proton beam strikes a target yielding neutrons which are absorbed by a high isotopic purity 7Li converter, yielding 8Li whose resulting decay yields the antineutrinos. In this note, we use FLUKA and GEANT4 simulations to investigate three proposed modifications of this standard proposal. In the first, the 7Li is replaced with 7Li compounds including a deuterium moderator. In the second, a gap is placed between the target and the converter to reduce the neutron bounce-back. Finally, we consider cooling the converter with liquid nitrogen. We find that these modifications can increase the antineutrino yield by as much as 50 percent. The first also substantially reduces the quantity of high purity 7Li which is needed.

description: Forecasts by the European Centre for Medium-Range Weather Forecasts (ECMWF; EC for short) can provide a basis for the establishment of maritime-disaster warning systems, but they contain some systematic biases.The fifth-generation EC atmospheric reanalysis (ERA5) data have high accuracy, but are delayed by about 5 days. To overcome this issue, a spatiotemporal deep-learning method could be used for nonlinear mapping between EC and ERA5 data, which would improve the quality of EC wind forecast data in real time. In this study, we developed the Multi-Task-Double Encoder Trajectory Gated Recurrent Unit (MT-DETrajGRU) model, which uses an improved double-encoder forecaster architecture to model the spatiotemporal sequence of the U and V components of the wind field; we designed a multi-task learning loss function to correct wind speed and wind direction simultaneously using only one model. The study area was the western North Pacific (WNP), and real-time rolling bias corrections were made for 10-day wind-field forecasts released by the EC between December 2020 and November 2021, divided into four seasons. Compared with the original EC forecasts, after correction using the MT-DETrajGRU model the wind speed and wind direction biases in the four seasons were reduced by 8-11% and 9-14%, respectively. In addition, the proposed method modelled the data uniformly under different weather conditions. The correction performance under normal and typhoon conditions was comparable, indicating that the data-driven mode constructed here is robust and generalizable.

description: This work reports on models described by two real scalar fields coupled with gravity in the five-dimensional spacetime, with a warped geometry involving one infinite extra dimension. Through a mechanism that smoothly changes a thick brane into a hybrid brane, one investigates the appearance of hybrid branes hosting internal structure, characterized by the splitting on the energy density and the volcano potential, induced by the parameter which controls interactions between the two scalar fields. In particular, we investigate distinct symmetric and asymmetric hybrid brane scenarios.

description: We give a proof of existence and uniqueness of viscosity solutions to parabolic quasilinear equations for a fairly general class of nonconvex Hamiltonians with superlinear growth in the gradient variable. The approach is mainly based on classical techniques for uniformly parabolic quasilinear equations and on the Lipschitz estimates proved in [S.N. Armstrong and H.V. Tran, Viscosity solutions of general viscous Hamilton-Jacobi equations, Math. Ann., 361 (2015)], as well as on viscosity solution arguments.

Linking the trophic function of estuaries to characteristics of their catchments

description: Our understanding of the interactions between terrestrial river catchments and estuarine ecology needs to be strengthened. The conversion of natural catchments to human land uses generally increases nutrient inputs to estuaries. Nutrient enrichment can disrupt ecological processes, including primary and secondary production and consumer trophic and population dynamics. These changes can alter the composition and trophic characteristics of consumer assemblages. This thesis details four complementary studies investigating relationships among catchment land use, nutrient loading, the instream consequences of nutrient loading, and the composition, trophic organization and nutritional support of estuarine fish assemblages. The estuary catchments investigated spanned a gradient of land use from highly altered to some largely intact catchments. Catchment land use was associated with the composition of estuarine fish assemblages (Chapter 2). The proportion of demersal species (i.e. species that inhabit the water column near to, and influenced by, the benthos) in fish assemblages was associated negatively with catchment land uses that are expected to increase nutrient loads (e.g. animal production, horticulture, industry and urbanization). My subsequent investigations suggested that this relationship reflected changes in habitat, especially the dominance of macroalgae over seagrass, which is induced by nutrient enrichment (Chapter 5). The proportion of urbanization in catchments was positively related to the nitrogen stable isotope (δ¹⁵N) values of large-bodied fish (Chapter 3). There was no relationship between δ¹⁵N and agricultural land uses, which substantially contribute to nitrogen loads of many Victorian estuaries. The lack of relationships between δ¹⁵N values in estuaries and the extent of agriculture in catchments suggests that bulk δ¹⁵N values are affected by mixing of isotopic sources or by the non-uniformity in nitrogen transformations among catchments distributed over hundreds of kilometres. Nutrient loading to estuaries influenced the trophic organization of fish assemblages (Chapter 4). Greater trophic diversity and less redundancy was seen at moderate to high inorganic nitrogen loading. This relationship may reflect the greater productivity and availability of vegetated demersal habitat. My subsequent investigations showed the contribution of demersal primary producers to fish nutrition did not reflect the relative availabilities of those resources in estuaries, which may be due to hypoxic conditions and habitat structure restricting the trophic transfer of some demersal resources to fish (Chapter 5). Findings from this thesis emphasise the need to integrate more fully the ecology of estuaries with that of their catchments, and then apply this to the management of estuarine ecosystems, particularly in the current era of rapid coastal development.

description: It is indisputable that physical activity is vital for an individual's health and wellness. However, a global prevalence of physical inactivity has induced significant personal and socioeconomic implications. In recent years, a significant amount of work has showcased the capabilities of self-tracking technology to create positive health behavior change. This work is motivated by the potential of personalized and adaptive goal-setting techniques in encouraging physical activity via self-tracking. To this end, we propose UBIWEAR, an end-to-end framework for intelligent physical activity prediction, with the ultimate goal to empower data-driven goal-setting interventions. To achieve this, we experiment with numerous machine learning and deep learning paradigms as a robust benchmark for physical activity prediction tasks. To train our models, we utilize, "MyHeart Counts", an open, large-scale dataset collected in-the-wild from thousands of users. We also propose a prescriptive framework for self-tracking aggregated data preprocessing, to facilitate data wrangling of real-world, noisy data. Our best model achieves a MAE of 1087 steps, 65% lower than the state of the art in terms of absolute error, proving the feasibility of the physical activity prediction task, and paving the way for future research.

description: Understanding the causal influences that hold among parts of a system is critical both to explaining that system's natural behaviour and to controlling it through targeted interventions. In a quantum world, understanding causal relations is equally important, but the set of possibilities is far richer. The two basic ways in which a pair of time-ordered quantum systems may be causally related are by a cause-effect mechanism or by a common cause acting on both. Here, we show a coherent mixture of these two possibilities. We realize this nonclassical causal relation in a quantum optics experiment and derive a set of criteria for witnessing the coherence based on a quantum version of Berkson's effect, whereby two independent causes can become correlated upon observation of their common effect. The interplay of causality and quantum theory lies at the heart of challenging foundational puzzles, including Bell's theorem and the search for quantum gravity.
