description: We derive a rate of convergence of the Loewner driving function for planar loop-erased random walk to Brownian motion with speed 2 on the unit circle, the Loewner driving function for radial SLE(2). The proof uses a new estimate of the difference between the discrete and continuous Green's functions that is an improvement over existing results for the class of domains we consider. Using the rate for the driving process convergence along with additional information about SLE(2), we also obtain a rate of convergence for the paths with respect to the Hausdorff distance.

Destabilising effect of resistive transverse dampers
Creators: name: Métral, E.
Publisher: name: CERN Yellow Reports: Conference Proceedings
Year: 2020

description: A resistive transverse damper is needed for multi-bunch operation in a machine like the CERN LHC and it is very efficient as it considerably reduces the necessary amount of nonlinearities (from octupoles) needed to reach beam stability through Landau damping. However, a resistive transverse damper also destabilizes the single-bunch motion below the transverse mode coupling instability (TMCI) intensity threshold (for zero chromaticity), introducing a new kind of instability, which has been called “ISR instability” (for Imaginary tune Split and Repulsion). The purpose of this contribution is to explain in detail this new instability mechanism and its mitigation.

description: Transverse head-tail instability is a major limitation for the single-bunch beam current in circular accelerators. Beam-based feedback is one of the potential tools to suppress this type of instability. The feedback systems (transverse dampers) provide active suppression of the beam oscillations by electromagnetic fields, the amplitude of which is calculated in real time from the measured beam position. The effciency of the transverse dampers in combination with various chromaticity settings is discussed.

description: Collective effects in high intensity, high energy particle accelerators and colliders are becoming increasingly important as performance is continuously pushed to the limits. The mitigation of collective effects, in particular coherent beam instabilities, relies heavily on transverse feedback systems. The dimensioning of these feedback systems (i.e. power, bandwidth, pickup and kicker distribution) are key to the systems performance and its effectiveness in combating collective effect limitations. Consequently, their realistic modeling in computer simulation codes is also highly important. In this paper we will briefly outline recent developments in advanced modeling of transverse feedback systems in collective eects using the example of macroparticle simulation codes developed at CERN.

description: Partikelmethoden sind gitterfreie Verfahren zur Lösung partieller Differentialgleichungen. Diese Methoden sind besonders in der numerischen Strömungsmechanik beliebt. Dabei wird das Fluid zunächst räumlich in eine Menge an Partikeln diskretisiert, welche sich mit der Zeit entlang der Lagrangeschen Trajektorien des Fluids bewegen. Die beobachteten Größen des Fluids werden somit mit dem Fluss transportiert. Im Gegensatz zu klassischen, gitterbasierten Verfahren, wie etwa der Finite-Volumen- oder Finite-Elemente-Methode, enthalten die Zeitableitungen der Größen keinen konvektiven Anteil und sind daher einfacher zu berechnen. Aufgrund der Lagrangschen Betrachtungsweise eignen sich diese Methoden im Besonderen für Problemstellungen mit hohen Geschwindigkeiten oder freien Oberflächen. Ein weiterer Vorteil ist, dass einige Erhaltungsgleichungen, wie zum Beispiel die Massenerhaltung, automatisch erfüllt sind. Eines der bekanntesten und ältesten Partikelverfahren ist das Smoothed Particle Hydrodynamics (SPH) Verfahren. Diese Methode ist aufgrund ihrer einfachen Diskretisierungstechnik sehr beliebt, da sie neben den Partikeln nur eine festgelegte Kernfunktion verwendet, welche die Partikel glättet. Trotz einer Vielzahl an Anwendungen und teilweise beeindruckenden Resultaten ist das mathematische Verständnis dieser Methode jedoch noch beschränkt. In dieser Arbeit wird die Konvergenz des SPH Verfahrens untersucht. Hierfür wird das Verfahren auf die Eulergleichungen mit einer speziellen, barotropischen Zustandsgleichung angewendet. Es steht vor allem die Konvergenz des semi-diskreten Problems und die Entwicklung passender Kernfunktionen im Vordergrund. Das Ziel ist es, einen ersten Schritt in Richtung einer allgemeinen Konvergenztheorie für das SPH Verfahren zu geben. Unter Verwendung spezieller Bedingungen an die von dem SPH Verfahren verwendeten Kernfunktion werden Fehlerschranken für einen Energiefehlerterm hergeleitet, aus dem dann die punktweise Konvergenz des Verfahrens gefolgert wird. Dabei wird besonders zwischen dem Glättungsparameter und dem Diskretisierungsparameter unterschieden, um einen expliziten Zu-sammenhang beider Parameter herzuleiten. Aufbauend auf den Wendland Funktionen wird eine Klasse radialer Kernfunktionen mit kompaktem Träger entwickelt, die sowohl die Bedingungen der Theorie als auch numerische Anforderungen erfüllt. Die Theorie wird dann um eine Zeitdiskretisierung erweitert, die die Konvergenz des vollständig diskretisierten Systems demonstrieren soll. Numerische Experimente sollen schließlich die theoretischen Resultate verifizieren.
Towards a disciplined seeing : a study in the work of Heidegger and Rilke
Creators: name: Hingston, Matthew
Publisher: name: University Of Tasmania

description: Topic: Towards a disciplined seeing: A study in the work of Heidegger and Rilke. This paper has two main aims. The first is to examine a fundamental difference in the way of being of humans and that of the natural world. The second is to chart the dangers, responsibilities and possibilities of the human realm conferred by that difference. In order to accomplish these two aims I draw on the philosophical thought of Martin Heidegger and the poetry, prose and correspondence of Rainer Maria Rilke. A desire to approach non-human forms in an intense and sustained manner fires the first intention. The latter, finding its genesis in the knowledge imparted through such encounters, and firmly convinced of both their rarity and importance in the scope of the human domain, is concerned with the difficulties facing the pursuit of such experiences and, once attained, how such encounters can contribute to the protection of these non-human forms. The first part (chapters 2 to 4) is occupied with developing a largely theoretical account of the non-human world and an outline and 'diagnosis' of the problems of the human realm. The last part (chapters 5 and 6) is 'moral' and practical in temper, and moves toward a 'cure' to the difficulties outlined in the first part.

description: This is the second article in which we study the rotating Morse potential model for diatomic molecules using the tridiagonal J-matrix approach. Here, we improve further the accuracy of computing the bound states and resonance energies for this potential model from the poles of the S-matrix for arbitrary angular momentum. The calculation is performed using an infinite square integrable basis that supports a tridiagonal matrix representation for the reference Hamiltonian, which is included in the computations analytically without truncation. Our method has been applied to both the regular and inverted Morse potential with favorable results in comparison with available numerical data. We have also shown that the present method adds few significant digits to the accuracy obtained from the finite dimensional approach (e.g. the complex rotation method). Moreover, it allows us to handle easily both analytic and non-analytic potentials as well as 1/r singular potentials.

Just a nurse : a critical exploration of how general medical nurses regard their practice
Creators: name: Marlow, AH
Publisher: name: University Of Tasmania
Year: 2023

description: It is argued that the provision of fundamental nursing care is the very essence of what it means to be a nurse. However, in contemporary health care contexts the pursuit of increased efficiencies has seen the concern with care diminish. The literature indicates that in these circumstances, the key providers of care to patients in hospitals, general medical nurses, are less than happy with the situation. In part this is reflected in the problems currently facing health care agencies with recruiting and retaining nurses. In a climate where recruitment and retention of experienced nurses is a major political issue, it is interesting to note that within the nursing literature, there is a virtual absence of research which addresses the issues and concerns of nurses who choose to work in a general medical ward setting. In order to begin the process of addressing this hiatus, this study utilized a critical research. method to explore the issues and concerns of five nurses who work as general medical nurses. Consistent with research that has a critical intent, the nurses engaged in 'critical dialogues' which were analysed and developed into a discussion paper. The discussion paper was then returned to the nurses, and the issues raised were subjected to considerable debate when the participants subsequently met as a group. The findings of the research provide keen insights into the experiences, issues and concerns of this group of general medical nurses. They highlight the operation of an array of conflicting interests which negatively impact on the capacity of general medical nurses to provide quality nursing care. Significantly, the perceived lowering of standards of patient care has caused the participants of this study to question their integrity and identity as nurses. However, given the opportunity to engage in a dialogue and to critically reflect on the issues raised, the nurses developed new insights into their situation which affirmed their worth as general medical nurses.

description: Wavelets offer significant advantages for the analysis of problems in quantum mechanics. Because wavelets are localized in both time and frequency they avoid certain subtle but potentially fatal conceptual errors that can result from the use of plane wave or delta function decomposition. Morlet wavelets are particularly well-suited for this work: as Gaussians, they have a simple analytic form and they work well with Feynman path integrals. To take full advantage of Morlet wavelets we need an explicit form for the inverse Morlet transform and a manifestly covariant form for the four-dimensional Morlet wavelet. We supply both here.

description: The main goal of behavioural neuroscience is to better understand the reciprocal relationships between neural activity and animal behaviour to aid in the treatment of a variety of neurological and psychiatric disorders. New breakthrough technologies in neuroscience give new hope for understanding the neural control of behaviour, yet there remains an unmet demand for data analysis as data generation grows. This PhenoSys research aims to investigate behaviour in a stress-free social setting tofacilitate accurate assessment of an individual's cognitive behaviour. The necessity to evaluate activity in the home-cage and behaviour in touch screen expands the analytic pipeline for examined utility of DeepLabCut software. Since PhenoSys gives a daily raw data file at each experiment, the python code is implemented to extract specific changes related to activity monitor. To determine how learning affect behavioural adaptation, DeepLabCut approach is then developed. This cannot be done using traditional behavioural classification methods because of the volume of resources required.This thesis helps to bridge the growing divide between data collection and data analysis in the behaviour neuroscience, which is a crucial step towards understanding the development and treatment of neurological conditions.

description: Many birds in North and South America are experiencing significant decline due to urbanization and climate change resulting in new ecological interactions, outpacing their ability to adapt. The expansion of urban areas and human infrastructure has resulted in the fragmentation and loss of bird habitats. The Bird-Safe City project is an important initiative that seeks to address the decline in bird populations resulting from collisions within the built environment, contributing to a global biodiversity crisis. By providing recommendations to update the existing City of Toronto's Bird-Friendly Development Guidelines, this project aims to incorporate bird-safe design practices into urban planning policies to minimize the impact of urbanization on biodiversity loss. This project's primary objectives include comprehensive research on bird-safe planning and design, a policy scan, and an examination of emerging standards.
Constraints on the presence of water megamaser emission in z~2.5 ultraluminous infrared starburst galaxies

description: We present Expanded Very Large Array and Arecibo observations of two lensed submm galaxies at z~2.5, in order to search for redshifted 22.235 GHz water megamaser emission. Both SMM J14011+0252 and SMM J16359+6612 have multi-wavelength characteristics consistent with ongoing starburst activity, as well as CO line emission indicating the presence of warm molecular gas. Our observations do not reveal any evidence for H2O megamaser emission in either target, while the lensing allows us to obtain deep limits to the H_2O line luminosities, L(H2O) < 7470 Lsun (3-sigma) in the case of SMM J14011+0252, and L(H2O) < 1893 Lsun for SMM J16359+6612, assuming linewidths of 80 km/s. Our search for, and subsequent non-detection of H2O megamaser emission in two strongly lensed starburst galaxies, rich in gas and dust, suggests that such megamaser emission is not likely to be common within the unlensed population of high-redshift starburst galaxies. We use the recent detection of strong H2O megamaser emission in the lensed quasar, MG J0414+0534 at z = 2.64 to make predictions for future EVLA C-band surveys of H2O megamaser emission in submm galaxies hosting AGN.

Analysis of the recreational use of municipal water-supply areas
Creators: name: Moffat, Melvin G.
Publisher: name: University of British Columbia
Year: 2011

description: A questionnaire survey of municipal water-supply agencies British Columbia, Washington, Oregon, and California was conducted for the purpose of comparing present management policies within and among the regions. Regression techniques were employed in an attempt to determine what factors influence the intensity of recreation occurring on a reservoir or watershed. A search of available literature was made to establish the 'facts' regarding water contamination through recreational use, the transmission of disease through water supplies, and the treatment of water to eliminate bacteria and viruses. The costs involved in the use or non-use of domestic water-supply areas for recreation were examined as were the major arguments for and against recreational use of these areas. The analysis of the questionnaire returns showed that in comparison with British Columbia, the States of Washington, Oregon and California all exhibited a higher level of water-supply management. Secondary uses were most prevalent in California and all of the respondents classifying themselves as 'secondary-use' agencies included recreation as one of the uses. In contrast to the situation in Washington and Oregon, and especially in British Columbia, recreational use in California was primarily a regulated use and very often planned and managed in detailed fashion with strict controls. The regression and correlation analysis showed some statistically significant but very weak relationships. The equations produced accounted for very little of the variation in the dependent variable (recreational-use score) and had very large standard errors of estimate. For the systems analyzed, the intensity of recreation occurring on a reservoir or watershed was related to such agency characteristics as present population served, percentage domestic use, degree of water treatment, average percentage of municipally or agency managed lands, average percentages of forest and shrub covered buffer and watershed lands and recreation opportunity in surrounding areas. From the search of pertinent literature and the questionnaire results, it was established that well planned and managed recreation facilities can be operated in conjunction with domestic water-supply facilities and have minimal effects on raw water quality. The potential hazard of disease transmission through the water system was fully recognized; however, water treatment techniques that will reduce this risk to a minimum are presently, available. On the basis of the research carried out in this study it was concluded that when conducted in accord with an ecologically sound management plan, recreation and the production of high quality potable water are indeed mutually compatible land uses.
Propagation of Electromagnetic Waves in Resistive Pair Plasma and Causal Relativistic Magnetohydrodynamics

Publisher: name: arXiv
Year: 2008
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: We investigate the propagation of electromagnetic waves in resistive pair plasmas using a onefluid theory derived from the relativistic two-fluid equations. When the resistivity normalized by the electron/positron inertia variable exceeds a critical value, the dispersion relation for electromagnetic waves shows that the group velocity is larger than the light speed in vacuum. However, in such a case, it also is found that the plasma parameter is less than unity: that is, the electron-positron pair medium no longer can be treated as plasma. Thus the simple two-fluid approximation is invalid. This confirms that superluminal propagation of electromagnetic wave is forbidden in a plasma -- a conclusion consistent with the relativistic principle of causality. As an alternative, we propose a new set of equations for ``causal relativistic magnetohydrodynamics", which both have non-zero resistivity and yet are consistent with the causality principle.

Marine protected areas and marine education : a case study of Tasmania and Victoria
Creators: name: Kasai, R
Publisher: name: University Of Tasmania
Year: 2023

description: Throughout the world, Marine Protected Areas (MPAs) have been declared mainly for biodiversity conservation and scientific purposes. However, the establishment and management of MPAs has not adequately addressed their important educational benefits. Interpretation signs and dive trails can be found at educationally managed MPAs that encourage the public to deepen their knowledge on the relatively undisturbed local marine environment. Education at both school and community levels need long-term commitment, nevertheless it can generate appreciation and support for conserving the marine environment. There are two aims for the thesis: to identify educational policies, strategies and opportunities to promote MPAs in Victoria and Tasmania; and to assess factors that could enhance MPAs for education purposes in Tasmania. In addition, four objectives were identified: to outline the development of MPAs at national and state levels; to review and analyse school and community based marine education programs in Victoria and Tasmania; to conduct a questionnaire and assess the degree of commitment of government and non-governmental organisations to marine education and MPAs; and to identify MPAs that could be used to support marine education for schools and the community. Research questionnaires were distributed to key informants involved in MPAs and marine education in Tasmania and Victoria. The questionnaires were distributed in order to investigate existing marine education policies, strategies and programs, values and use of MPAs for educational purposes, resources for marine educational activities, impediments to their implementation and marine education programs for promoting the development of MPAs. The conclusion shows that despite a recent increase in concern about the marine environment, the development of marine education policy and programs through the declaration of MPAs has been inadequate in Tasmania. The study recommends the designation and expansion of a number of Tasmanian MPAs for educational use.

description: Among the methods for solving ODE-IVPs, the class of General Linear Methods (GLMs) is able to encompass most of them, ranging from Linear Multistep Formulae (LMF) to RK formulae. Moreover, it is possible to obtain methods able to overcome typical drawbacks of the previous classes of methods. For example, order barriers for stable LMF and the problem of order reduction for RK methods. Nevertheless, these goals are usually achieved at the price of a higher computational cost. Consequently, many efforts have been made in order to derive GLMs with particular features, to be exploited for their efficient implementation. In recent years, the derivation of GLMs from particular Boundary Value Methods (BVMs), namely the family of Generalized BDF (GBDF), has been proposed for the numerical solution of stiff ODE-IVPs. In particular, this approach has been recently developed, resulting in a new family of L-stable GLMs of arbitrarily high order, whose theory is here completed and fully worked-out. Moreover, for each one of such methods, it is possible to define a corresponding Blended GLM which is equivalent to it from the point of view of the stability and order properties. These blended methods, in turn, allow the definition of efficient nonlinear splittings for solving the generated discrete problems. A few numerical tests, confirming the excellent potential of such blended methods, are also reported.

Links between ontogeny, chemical and physical characteristics of foliage and mammalian herbivory in Eucalyptus nitens
Creators: name: Loney, Prue Elizabeth
Publisher: name: University Of Tasmania
Year: 2023

description: Throughout plant development from seeds to seedlings, juveniles and mature stages a plant's palatability or resistance to herbivory is likely to change. Such ontogenetic changes can be due to changes in chemical and physical characteristics of the foliage. Consequently, herbivores often prefer to feed on particular plant ontogenetic stages. The research presented in this thesis focuses on the effects of plant ontogeny on chemical and physical characteristics of Eucalyptus nitens foliage, and flow on effects for mammalian herbivory by the common brushtail possum (Trichosurus vulpecula), and the red-bellied pademelon (Thylogale billardierii). My research demonstrates that large changes in foliage chemical and/or physical characteristics occur during the early seedling stage, between young and old leaves within seedlings, and between juvenile and adult leaves within 4-year-old trees. Furthermore, evidence from feeding trials implies that these changes are likely to be associated with changes in mammalian herbivory. No single chemical or physical characteristic of the foliage could explain the patterns of herbivory observed across the onto genetic stages studied. In fact, certain chemical or physical characteristics affected foliage resistance to mammalian herbivores at some ontogenetic stages but not at others. Furthermore, the importance of particular chemical and physical characteristics differed between brushtail possums and pademelons, and under the types of conditions they were offered the foliage (i.e. no-choice and choice trials). Chemical analyses suggested that newly emerged seedlings become more protected from mammalian herbivores as they increased in age, with chemicals known to deter these herbivores (sideroxylonals and cineole) being present in minute quantities at seedling emergence. Within seedlings, pademelons preferred older leaves that contained the lowest concentration of sideroxylonals and cineole, while possums generally preferred young leaves high in sideroxylonals and cineole, but also high in nitrogen. Under choice conditions possums preferred juvenile over adult tree foliage, while under no-choice conditions they consumed as much adult foliage as juvenile. These results suggested that difference in leaf toughness affected feeding preference under choice condition but not under no-choice conditions. Currently ecological and evolutionary theories regarding interactions between plants and herbivores are largely based on studies conducted at a single ontogenetic stage. However, the large effects of ontogeny on the chemical and/or physical characteristics of the foliage and its palatability to herbivores shown in this thesis emphasise Boege and Marquis' (2005) assertion that the role of ontogeny should be an important component in plant defence theories.

description: The Mallows model on $S_n$ is a probability distribution on permutations, $q^{d(π,e)}/P_n(q)$, where $d(π,e)$ is the distance between $π$ and the identity element, relative to the Coxeter generators. Equivalently, it is the number of inversions: pairs $(i,j)$ where $1\leq iπ_j$. Analyzing the normalization $P_n(q)$, Diaconis and Ram calculated the mean and variance of $d(π,e)$ in the Mallows model, which suggests the appropriate $n \to \infty$ limit has $q_n$ scaling as $1-β/n$. We calculate the distribution of the empirical measure in this limit, $u(x,y) dx dy = \lim_{n \to \infty} \frac{1}{n} \sum_{i=1}^{n} δ_{(i,π_i)}$. Treating it as a mean-field problem, analogous to the Curie-Weiss model, the self-consistent mean-field equations are $\frac{\partial^2}{\partial x \partial y} \ln u(x,y) = 2 βu(x,y)$, which is an integrable PDE, known as the hyperbolic Liouville equation. The explicit solution also gives a new proof of formulas for the blocking measures in the weakly asymmetric exclusion process, and the ground state of the $\mathcal{U}_q(\mathfrak{sl}_2)$-symmetric XXZ ferromagnet.

Dirac Mixture Approximation of Multivariate Gaussian Densities

Publisher: name: Karlsruhe
Year: 2009

description: For the optimal approximation of multivariate Gaussian densities by means of Dirac mixtures, i.e., by means of a sum of weighted Dirac distributions on a continuous domain, a novel systematic method is introduced. The parameters of this approximate density are calculated by minimizing a global distance measure, a generalization of the well-known Cram\'{e}r- von Mises distance to the multivariate case. This generalization is obtained by defining an alternative to the classical cumulative distribution, the Localized Cumulative Distribution (LCD). In contrast to the cumulative distribution, the LCD is unique and symmetric even in the multivariate case. The resulting deterministic approximation of Gaussian densities by means of discrete samples provides the basis for new types of Gaussian filters for estimating the state of nonlinear dynamic systems from noisy measurements.
A Class I and Class II Methanol Maser Survey of Extended Green Objects (EGOs) from the GLIMPSE Survey

description: We present the results of a high angular resolution Very Large Array (VLA) Class I 44 GHz and Class II 6.7 GHz methanol maser survey of a sample of ~20 massive young stellar object (MYSO) outflow candidates selected on the basis of extended 4.5 micron emission in Spitzer Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) images. These 4.5 micron-selected candidates are referred to as extended green objects (EGOs), for the common coding of this band as green in three-color IRAC images. The detection rate of 6.7 GHz Class II methanol masers, which are associated exclusively with massive YSOs, towards EGOs is greater than ~64%--nearly double the detection rate of surveys using other MYSO selection criteria. The detection rate of Class I 44 GHz methanol masers, which trace molecular outflows, is ~89% towards EGOs associated with 6.7 GHz methanol masers. The two types of methanol masers exhibit different spatial distributions: 6.7 GHz masers are centrally concentrated and usually coincide with 24 micron emission, while 44 GHz masers are widely distributed and generally trace diffuse 4.5 micron features. We also present results of a complementary James Clerk Maxwell Telescope (JCMT) single-pointing molecular line survey of EGOs in the outflow tracers HCO+(3-2) and SiO(5-4). The HCO+ line profiles and high SiO detection rate (90%) are indicative of the presence of active outflows. No 44 GHz continuum emission is detected at the 5 mJy/beam (5 sigma) level towards 95% of EGOs surveyed, excluding bright ultracompact HII regions as powering sources for the 4.5 micron outflows. The results of our surveys constitute strong evidence that EGOs are young, massive YSOs, with active outflows, presumably powered by ongoing accretion.

Morphological effects of estrogen removal on an estrogen-dependent adrenocortical carcinoma in rats
Creators: name: Nichols, Thomas Matthew
Publisher: name: University of British Columbia
Year: 2011

description: The morphologic effects of estrogen withdrawal from an estrogen-dependent tumor were investigated using light and electron microscopy. Twenty-five male hooded rats received interscapular implants of an estrogen-induced, estrogen-dependent adrenocortical tumor as well as subcutaneous estrone pellets. The tumors were examined when they had reached one and two centimeters in size. The pellets were removed from a second group and the tumors examined when they had decreased to a minimum size. A third group received a second pellet after the tumor had regressed to a minimum size following removal of the first pellet. The primary tumors were characterized by plump, active-looking cells growing usually in a sheet-like pattern. The ultrastructural features of these tumors included large, bizarre mitochondria with tubular cristae, prominent polyribosomal aggregates and Golgi zones as well as fairly frequent centrioles. The regressing tumors consisted of smaller cells growing in a trabecular pattern and heavily infiltrated with eosinophils. The fine structure of the tumor cells consisted of small mitochondria with a dense matrix and a few irregular cristae. Myelin figures and residual bodies were present in significant numbers only in the regressing tumors while (primary)lysosomes were more frequent in the growing tumors. The tumors examined after reimplantation of estrone showed features of the primary growth tumors plus residual foci of regression. It thus appears that estrogen acts as a trophic factor for this experimental tumor much as it does for the uterus. Tumor cells can survive in its absence, but require it for growth. The ultrastructural expression of estrogen administration seen in this study is the proliferation of mitochondria as an energy source and polyribosomes for the production of proteins for endogenous consumption. The removal of estrogen results in a generalized reduction in cellular activity and an accumulation of the products of autophagy. Further work is required to tie in these results with the studies being done on the basic mechanisms of estrogen action at the level of molecular biology.
A comparative study of approaches to learing [i.e. learning] of Chinese background students from mainland China, Hong Kong, Malaysia and Singapore in Australian educational discourse

Publisher: name: University Of Tasmania

description: The aim of this PhD research is to uncover different Chinese nationals' approaches to learning with a view to enhancing their learning efficiency as well as informing approaches to Australian course design and delivery. In a broader sense, this research aims to explore the national identities of Chinese students from differing backgrounds (mainland China, Hong Kong, Malaysia, and Singapore). Quantitative and qualitative approaches were used in this study. 179 Chinese students at two Australian universities participated in the questionnaire of OECD model with a focus on learning strategies, motivation, self-related beliefs and learning preferences. Several students participated individually in an interview. According to the findings, there was a consistency among Chinese students of different regions in their views and behaviours about their approaches to learning in tertiary education in Australia. However there were also some differences in regards to the use of some learning strategies. For example, Mainland Chinese students strongly valued the function of understanding in learning and the use of elaboration strategies. They also showed more instrumental motivation than interest compared to other groups. Hong Kong students strongly favoured memorization strategies in the belief that repetition could improve understanding. The analysis of the interview data gave important insights about their views on learning, national identity, and academic achievement.

description: Stein's method is applied to obtain a general Cramer-type moderate deviation result for dependent random variables whose dependence is defined in terms of a Stein identity. A corollary for zero-bias coupling is deduced. The result is also applied to a combinatorial central limit theorem, a general system of binary codes, the anti-voter model on a complete graph, and the Curie-Weiss model. A general moderate deviation result for independent random variables is also proved.

Heart Surface Motion Estimation Framework for Robotic Surgery Employing Meshless Methods

description: A novel heart surface motion estimation frame- work for a robotic surgery on a stabilized beating heart is proposed. It includes an approach for the reconstruction and prediction of heart surface motion based on a novel physical model of the intervention area described by a distributed- parameter system. Instead of conventional element methods, a meshless method is used for a spatial and temporal decomposi- tion of this system. This leads to a finite-dimensional state-space form. Furthermore, the state of the resulting lumped-parameter system, which provides an approximation of the deflection and velocity of the heart surface, is dynamically estimated under consideration of uncertainties both occurring in the system and arising from noisy camera measurements. By using the estimation results, an accurate reconstruction of heart surface motion for the synchronisation of the surgical instruments is also achieved at occluded or non-measurement points.
