description: Let G be a universal Chevalley group over an algebraically closed field and U^- be the subalgebra of Dist(G) generated by all divided powers X_{α,m} with α<0. We conjecture an algorithm to determine if Fe^+_ω\ne0, where F\in\U^-, ωis a dominant weight and e^+_ωis a highest weight vector of the Weyl module Δ(ω). This algorithm does not use bases of Δ(ω) and is similar to the algorithm for irreducible modules that involves stepwise raising the vector under investigation. For an arbitrary G, this conjecture is proved in one direction and for G of type A in both.
The crystallisation history of normal mid-ocean ridge basalts from the Eastern Pacific Ocean and implications for the composition of primary mid-ocean ridge magmas : evidence from mineralogy, pillow-rim glasses and melt inclusion studies
Creators: name: McNeill, Andrew
Publisher: name: University Of Tasmania
Year: 2023

description: An understanding of MORB petrogenesis requires compositional data on primary melts, as these provide direct information on the PT-conditions and mechanisms of mantle melting and melt segregation beneath mid-ocean ridges. The reconstruction of primary melts from the compositions of erupted liquids (pillow-rim glasses) requires an understanding of the early crystallisation history of the primary melts. As recent models of MORB petrogenesis imply that not only early crystallisation, but, also extensive mixing of primary melts occurs, information on the early stages of evolution of the primary melts is even more crucial. Such information may be preserved by early formed phenocrysts and can be obtained by studying these phenocrysts and their melt inclusions. However, the ability of melt inclusions to preserve the compositions of trapped liquids needs to be examined (e.g., homogenised melt inclusions in cotectic phenocrysts should have the same compositions, and those trapped during a period of fractionation, as recorded by the pillow-rim glasses, should have compositions similar to the glasses). The three MORB suites described in this thesis are from ODP/DSDP Holes 896A and 504B, Costa Rica Rift, and Sample D9-1 from the Gorda Ridge, in the east Pacific Ocean. Compositional and textural variations of phenocrysts (olivine, plagioclase and spine!) have been used to interpret the crystallisation history for each suite and, together with pillow-rim glass compositions, form the basis for interpreting the compositional variations of melt inclusions. Samples from the Costa Rica Rift and the Gorda Ridge have phenocryst assemblages dominated by calcic plagioclase (>An\\(_{88}\\)) with lesser olivine (

Small semigroup related structures with infinite properties
Creators: name: Jackson, MG
Publisher: name: University Of Tasmania
Year: 2023

description: In mathematics, one frequently encounters constructions of a pathological or critical nature. In this thesis we investigate such structures in semigroup theory with a particular aim of finding small, finite, examples with certain associated infinite characteristics. We begin our investigation with a study of the identities of finite semigroups. A semigroup (or the variety it generates) whose identities admit a finite basis is said to be finitely based. We find examples of pairs of finite (aperiodic) finitely based semigroups whose direct product is not finitely based (answering a question of M. Sapir) and of pairs of finite (aperiodic) semigroups that are not finitely based whose direct product is finitely based. These and other semigroups from a large class (the class of finite Rees quotients of free monoids) are also shown to generate varieties with a chain of finitely generated supervarieties which alternate between being finitely based and not finitely based. Furthermore it is shown that in a natural sense, \almost all\" semigroups from this class are not finitely based. Not finitely based semigroups that are locally finite and have the property that every locally finite variety containing them is also not finitely based are said to be inherently not finitely based. We construct all minimal inherently not finitely based divisors in the class of finite semigroups and establish several results concerning a fundamental example with this property; the six element Brandt semigroup with adjoined identity element B. 1/2. We then find the first examples of finite semigroups admitting a finite basis of identities but generating a variety with uncountably many subvarieties (indeed with a chain of subvarieties with the same ordering as the real numbers). For some well known classes a complete description of the members with this property are obtained and related examples and results concerning joins of varieties are also found. A connection between these results and the construction of varieties with decidable word problem but undecidable uniform word problem is investigated. Finally we investigate several embedding problems not directly concerned with semigroup varieties and show that they are undecidable. The first and second of these problems concern the fundamental relations of Green; in addition some small examples are found which exhibit unusual related properties and a problem of M. Sapir is solved. The third of the embedding problems concerns the potential embeddability of finite semigroup amalgams. The results are easily extended to the class of rings."

A Metric and Optimisation Scheme for Microlens Planet Searches

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: OGLE III and MOA II are discovering 600-1000 Galactic Bulge microlens events each year. This stretches the resources available for intensive follow-up monitoring of the lightcurves in search of anomalies caused by planets near the lens stars. We advocate optimizing microlens planet searches by using an automatic prioritization algorithm based on the planet detection zone area probed by each new data point. This optimization scheme takes account of the telescope and detector characteristics, observing overheads, sky conditions, and the time available for observing on each night. The predicted brightness and magnification of each microlens target is estimated by fitting to available data points. The optimisation scheme then yields a decision on which targets to observe and which to skip, and a recommended exposure time for each target, designed to maximize the planet detection capability of the observations. The optimal strategy maximizes detection of planet anomalies, and must be coupled with rapid data reduction to trigger continuous follow-up of anomalies that are thereby found. A web interface makes the scheme available for use by human or robotic observers at any telescope. We also outline a possible self-organising scheme that may be suitable for coordination of microlens observations by a heterogeneous telescope network.

description: Recently, it has been shown that spin nematic (quadrupolar) or higher multipolar correlation functions exhibit a quasi long-range order in the wide region of the field-induced Tomonaga-Luttinger-liquid (TLL) phase in spin-1/2 zigzag chains. In this paper, we point out that the temperature dependence of the NMR relaxation rate 1/T_1 in these multipolar TLLs is qualitatively different from that in more conventional TLLs of one-dimensional quantum magnets (e.g., the spin-1/2 Heisenberg chain); 1/T_1 decreases with lowering temperature in multipolar TLL. We also discuss low-energy features in spin dynamical structure factors which are characteristic of the multipolar TLL phases.

Publisher: name: arXiv
Year: 2023
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: Venn Prediction (VP) is a new machine learning framework for producing well-calibrated probabilistic predictions. In particular it provides well-calibrated lower and upper bounds for the conditional probability of an example belonging to each possible class of the problem at hand. This paper proposes five VP methods based on Neural Networks (NNs), which is one of the most widely used machine learning techniques. The proposed methods are evaluated experimentally on four benchmark datasets and the obtained results demonstrate the empirical well-calibratedness of their outputs and their superiority over the outputs of the traditional NN classifier.

description: In the future of higher education, student learning will become more virtual and group-oriented, and this new reality of academic learning comes with challenges. Positive social interactions in virtual synchronous student learning groups are not self-evident but need extra support. To successfully support positive social interactions, the underlying group processes, such as collaborative group engagement, need to be understood in detail, and the important question arises: How can collaborative group engagement be assessed in virtual group learning settings? A promising methodological approach is the observation of students’ non-verbal behavior, for example, in videoconferences. In an exploratory field study, we observed the non-verbal behavior of psychology students in small virtual synchronous learning groups solving a complex problem via videoconferencing. The groups were videorecorded to analyze possible relations between their non-verbal behaviors and to rate the quality of collaborative group engagement
Optimising deployment of Pinus radiata : an evaluation of methods for the propagation of cuttings and the estimation of genetic parameters to quantify gains from deploying with stecklings
Creators: name: McGranahan, Michelle Frances
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis investigates current and potential deployment strategies using stecldings of Pinus radiata. The investigations showed that the growth of stecldings at 9 months of age was influenced by the age of the stock plant from which they were propagated, the genotype, an interaction between these two effects, and stock plant source. Stock plants raised from seed showed the fastest growth rates and produced cuttings that also showed the fastest growth rates. Growth of stecldings declined with increasing stock plant age (2 to 5 years). It was also shown for most traits that estimates of genetic variance and heritabilities were similar for seedlings and stecldings propagated from 2 year-old stock plants, with very high genetic correlations between these propagule types. However inflated estimates of genetic variance and heritability were found for two out of three traits measured in stecklings propagated from 6 year-old stock plants. This was attributed to either dominance effects or propagation effects common to a fullsib family, C-effects. Also poor correspondence between the performances of seedlings and stecklings propagated from 6 year-old stock plants was found for one trait.Deployment of families as stecklings based on the performances of seedlings is viable for cuttings that come from young stock plants (up to 2 years of age). By comparison, the use of stecklings from older stock plants may bias the estimates of genetic merit in P. radiata and result in yields which differ from those expected from breeding programs. Age-age correlations were highest when comparing traits measured at later ages, between 6 and 11 years of age, rather than between 9 months and 6 years of age and 9 months and 11 years of age. It could not be shown whether selection of superior families can be carried out at an earlier age than is currently employed. The study also indicates that the deployment strategy for P. radiata which will provide the grower the highest potential economic benefit is clonal forestry. Two modelled scenarios predicted genetic gains of a clonal forestry deployment strategy to be at least 50 % greater than a family forestry deployment strategy.
Ordered States and Nonlinear Large-Scale Excitations in a Plane Magnet with Spin s=1

description: We study ordered states and topological excitations in a quasi-two-dimensional magnet, modeled by a square lattice with spins $s {=} 1$ at all sites, and the Hamiltonian with biquadratic exchange interaction between nearest neighbor sites. We propose two effective Hamiltonians for description of large-scale excitations in the two-dimensional case. They describe excitations of the mean field in a nematic phase and a mixed ferromagnetic-nematic phase. It is shown that the effective Hamiltonians are minimized on configurations with fixed topological charge. These topological excitations can arise at low temperatures and cause a destruction of a long-range order in the two-dimensional system.

description: Obsolete devices add to the rising levels of electronic waste, a major environmental concern, and a contributing factor to climate change. In recent years, device manufacturers have established environmental commitments and launched initiatives such as supporting the recycling of obsolete devices by making more ways available for consumers to safely dispose of their old devices. However, little support is available for individuals who want to continue using legacy or 'end-of-life' devices and few studies have explored the usefulness of these older devices, the barriers to their continued use and the associated user experiences. With a human-computer interaction lens, this paper reflects on device usefulness as a function of utility and usability, and on the barriers to continued device use and app installation. Additionally, the paper contributes insights from a sequel study that extends on prior work evaluating app functionality of a 'vintage' Apple device with new empirical data on app downloadability and functionality for the same device when newly classified as 'obsolete'. A total of 230 apps, comprising the top 10 free App Store apps for each of 23 categories, were assessed for downloadability and functionality on an Apple iPad Mini tablet. Although only 20 apps (8.7%) could be downloaded directly onto the newly obsolete device, 143 apps (62.2%) could be downloaded with the use of a different non-legacy device. Of these 163 downloadable apps, 131 apps (com-prising 57% of all 230 apps and 80.4% of the downloadable apps) successfully installed, opened, and functioned. This was a decrease of only 4.3% in functional apps (of the 230 total apps) compared to the performance of the device when previously classified as 'vintage'.

Simulation of growth, yield and management of aspen
Creators: name: Bella, Imre E
Publisher: name: University of British Columbia
Year: 2011

description: A semi-stochastic model was developed to simulate tree growth and stand yield information required for managing aspen (Populas tremuloides (Michx.)). The model is based upon new approaches for evaluating inter-tree competition effects, representing actual tree spatial arrangement, defining interactions between increments of height and d.b.h. and competition measures, and representing random components of variation in tree growth and mortality. In building the model, components of tree growth and mortality were identified and described mathematically or represented directly in the computer. Inter-tree competition, the most important component in the model, was extensively studied. The maximum zone of influence of a tree was derived from estimates of fully open grown crown width. A new hypothesis was advanced and mathematically expressed to describe competition effects on tree growth by exponential terms of ratios based on relative tree size. The model simulates height increments as if each tree was dominant or open-growing. The rate of height growth is a function of site quality. Simulated "potential" height increment is reduced, according to the tree's competitive status, to obtain height increment. D.b.h. increment is based on data from open grown aspen then reduced in proportion to tree competition. Reductions from the maximum rate of growth are based on tree growth and mortality expected in normal aspen stands. In the model mortality is directly related to the tree's competitive status and inversely to its current increment, including random variation, in relation to a specified threshold value. The model was calibrated with data from a normal stand growing on an above average aspen site in Saskatchewan. Input data were from a suitable permanent sample plot having fairly uniform clonal structure. After a few calibration runs and model refinements, simulated stand growth statistics showed satisfactory correspondence with actual growth on the permanent sample plot, and with comparable yield table statistics. Simulations were made also for normal stands growing on poor sites and on the best sites in the same region. The model was generally satisfactory and could replace normal yield tables. After certain extensions, the revised model also simulated growth and development of initially open stands reasonably well. The model also was used to simulate aspen stand growth and productivity in terms of tree component dry matter weights for normal stands on average sites with weight regressions determined in an associated study. For maximum production of wood fibre, the optimum rotation was 33 years for either volume or weight. Although tested only for pure aspen stands, the model can be modified for use with other species. With further refinement, it may be possible also to simulate the growth of mixed stands and uneven-aged stands.
The influence of age, sex and coeducation on gender cleavage and friendship quality during childhood and adolescence
Creators: name: Leeson, S
Publisher: name: University Of Tasmania
Year: 2023

description: The review aims to outline the theoretical background, methodological issues and the grade-related and sex differences in two main research areas of children's friendship, namely friendship choice and friendship quality. Gender cleavage is the propensity of children to choose, and rate more positively friends of the same-gender. Theoretical accounts of the establishment and maintenance of gender cleavage have focused largely on individual-level factors as the driving force behind this phenomenon and to a lesser extent, group processes. This review argues that, at a broader level, it is possible that environmental factors such as the gender composition of the school might influence gender cleavage. Friendship quality research investigates the thoughts, feelings and concepts children and adolescents have about their friends. Research within this area has concentrated on same-gender friendships and little research has been carried out in relation to children's and adolescent's perceptions of their opposite-gender peers compared to their same-gender peers. Friendship qualities in opposite-gender peers have also not been widely or systematically examined across sex or age. As in the gender cleavage research it is important to investigate how ideas of friendship quality may be related to oppositegender and same-gender friendship choices in gendered school environments. The review concludes that the two major areas of friendship research namely friendship choice and quality have developed separately and that there may be important connections between children's expectations and their actual friendship choices.

description: The reality and convexity of the effective potential in quantum field theories has been studied extensively in the context of Euclidean space-time. It has been shown that canonical and path-integral approaches may yield different results, thus resolving the `convexity problem'. We discuss the transferral of these treatments to Minkowskian space-time, which also necessitates a careful discussion of precisely which field configurations give the dominant contributions to the path integral. In particular, we study the effective potential for the N=1 linear sigma model.

description: Since smart cities aim at becoming self-monitoring and self-response systems, their deployment relies on close resource monitoring through large-scale urban sensing. The subsequent gathering of massive amounts of data makes essential the development of event-filtering mechanisms that enable the selection of what is relevant and trustworthy. Due to the rise of mobile event producers, location information has become a valuable filtering criterion, as it not only offers extra information on the described event, but also enhances trust in the producer. Implementing mechanisms that validate the quality of location information becomes then imperative. The lack of such strategies in cloud architectures compels the adoption of new communication schemes for Internet of Things (IoT)-based urban services. To serve the demand for location verification in urban event-based systems (DEBS), we have designed three different fog architectures that combine proximity and cloud communication. We have used network simulations with realistic urban traces to prove that the three of them can correctly identify between 73% and 100% of false location claims.

description: We consider the use of a running measure of power spectrum disorder to distinguish between the normal sinus rhythm of the heart and two forms of cardiac arrhythmia: atrial fibrillation and atrial flutter. This spectral entropy measure is motivated by characteristic differences in the spectra of beat timings during the three rhythms. We plot patient data derived from ten-beat windows on a "disorder map" and identify rhythm-defining ranges in the level and variance of spectral entropy values. Employing the spectral entropy within an automatic arrhythmia detection algorithm enables the classification of periods of atrial fibrillation from the time series of patients' beats. When the algorithm is set to identify abnormal rhythms within 6 s it agrees with 85.7% of the annotations of professional rhythm assessors; for a response time of 30 s this becomes 89.5%, and with 60 s it is 90.3%. The algorithm provides a rapid way to detect atrial fibrillation, demonstrating usable response times as low as 6 s. Measures of disorder in the frequency domain have practical significance in a range of biological signals: the techniques described in this paper have potential application for the rapid identification of disorder in other rhythmic signals.

Heavy metals and stormwater : an investigation of Hobart, Tasmania, Australia
Creators: name: Lee Wan Aik, D
Publisher: name: University Of Tasmania

description: Stormwater quality in the City of Hobart has been examined by past local studies. However, heavy metals were not critically examined in those studies. This research was undertaken to determine the levels of heavy metals discharged by three major rivulets namely, Sandy Bay Rivulet, Hobart Rivulet and New Town Rivulet into the Derwent Estuary. Nine stormwater samples were collected through grab sampling during the first-flush period at three rivulet sites, including street runoff and stormwater in the suburbs. The sampling period took place from October 2001 till February 2002. Levels of pH and total suspended solids (TSS) concentrations were measured. Levels of heavy metals such as Al, Cd, Cr, Co, Cu, Fe, Mn, Ni, Pn and Zn were determined using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP) in the laboratory. Total metals concentrations, sediment and dissolved heavy metals were calculated and compared against international and national standards. In addition, studies from past stormwater studies, including local studies were used as a benchmark in this study. Results show metals like Cu, Ni and Zn were found mainly in dissolved form while Pb, Al and Fe were mainly in particulate matter. High levels of dissolved Cu and Zn are found in Hobart and New Town Rivulets. Distribution and levels of heavy metals are found to be highly dependent on landuse across the three rivulets' catchments. High levels of Al and Fe were found to their abundance in the Earth's crust. High levels of Mn in Sandy Bay Rivulet were due to geologic makeup of Sandy Bay region. Other metals, excluding Cu, Pb and Zn are found to be within guidelines. Non-point sources such as residential areas and point sources have been identified as potential sources of metals. Zn concentrations are significantly higher than Pb and Cu. Heavy metals in street runoff sample reveal higher levels of Cu, Ni and Zn than Atlanta streets. Comparison with local studies reveal an increase in TSS in Sandy Bay Rivulet, increass in Zn levels in Hobart Rivulet and an overall higher level of heavy metals in stormwater sediment as compared to sediments in the Derwent Estuary. It is recommended reduction measures like efficient sediment traps should be installed at three rivulets, as well as source reduction programs to be adopted by the state government or local councils to curb the level of sedimentation, as well as the amount of heavy metals contaminated sediment from entering the Derwent Estuary.
Probing neutron correlations through nuclear break-up

description: The effect of initial correlations between nucleons on the nuclear break-up mechanism is studied. A quantum transport theory which extends standard mean-field approach is developed to incorporate short range pairing correlation as well as direct nucleon-nucleon collisions. A time evolution of the nuclear break-up from a correlated system leading to the emission of two particles to the continuum is performed. We show that initial correlations have strong influence on relative angles between particles emitted in coincidence. The present qualitative study indicates that nuclear break-up might be a tool to infer the residual interaction between nucleons in the nuclear medium.

description: Two approaches to describe the thermodynamics of a subsystem that interacts with a thermal bath are considered. Within the first approach, the mean system energy $E_{S}$ is identified with the expectation value of the system Hamiltonian, which is evaluated with respect to the overall (system+bath) equilibrium distribution. Within the second approach, the system partition function $Z_{S}$ is considered as the fundamental quantity, which is postulated to be the ratio of the overall (system+bath) and the bath partition functions, and the standard thermodynamic relation $E_{S}=-d(\ln Z_{S})/dβ$ is used to obtain the mean system energy. % ($β\equiv 1/(k_{B}T)$, $k_{B}$ is the Boltzmann constant, %and $T$ is the temperature). Employing both classical and quantum mechanical treatments, the advantages and shortcomings of the two approaches are analyzed in detail for various different systems. It is shown that already within classical mechanics both approaches predict significantly different results for thermodynamic quantities provided the system-bath interaction is not bilinear or the system of interest consists of more than a single particle. Based on the results, it is concluded that the first approach is superior.

description: With the rise of two-dimensional (2D) materials, unique properties that are completely distinct from bulk counterparts continue to emerge at low-dimensional scales, presenting numerous opportunities and challenges. It also provides a new perspective for the study of transition metal system. Here, based on density functional theory (DFT), the physical properties of 2D monolayer LiV2S4 have been studied. Remarkable changes have been observed, i.e., vanadium dimerization, ferromagnetism, charge distribution and metal-insulator transition (MIT). It is argued that the electronic instability leads to the V dimerization which further lifts the degeneracy of charge distribution and stabilizes the charge and spin ordering state.

description: Predictions of analytical models for hadronisation, namely the dispersive model, the shape function and the single dressed gluon approximation, are compared with moments of hadronic event shape distributions measured in \epem annihilation at centre-of-mass energies between 14 and 209 GeV. In contrast to Monte Carlo models for hadronisation, analytical models require to adjust only two universal parameters, the strong coupling and a second quantity parametrising nonperturbative corrections. The extracted values of as are consistent with the world average and competitive with previous measurements. The variance of event shape distributions is compared with predictions given by some of these models. Limitations of the models, probably due to unknown higher order corrections, are demonstrated and discussed.
