description: Detailed applications of minisuperspace methods are presented and compared with results obtained in recent years by means of causal dynamical triangulations (CDTs), mainly in the form of effective actions. The analysis sheds light on conceptual questions such as the treatment of time or the role and scaling behavior of statistical and quantum fluctuations. In the case of fluctuations, several analytical and numerical results show agreement between the two approaches and offer possible explanations of effects that have been seen in causal dynamical triangulations but whose origin remained unclear. The new approach followed here suggests `CDT experiments' in the form of new simulations or evaluations motivated by theoretical predictions, testing CDTs as well as the minisuperspace approximation.

description: Starting from Ooguri's construction for $BF$ theory in three (and four) dimensions, we show how to construct a well defined theory with an infinite number of degrees of freedom. The spin network states that are kept invariant by the evolution operators of the theory are exact solutions of the Hamiltonian constraint of quantum gravity proposed by Thiemann. The resulting theory is the first example of a well defined, finite, consistent, spin-foam based theory in a situation with an infinite number of degrees of freedom. Since it solves the quantum constraints of general relativity it is also a candidate for a theory of quantum gravity. It is likely, however, that the solutions constructed correspond to a spurious sector of solutions of the constraints. The richness of the resulting theory makes it an interesting example to be analyzed by forthcoming techniques that construct the semi-classical limit of spin network quantum gravity.

description: Inspired by the discrete evolution implied by the recent work on loop quantum cosmology, we obtain a discrete time description of usual quantum mechanics viewing it as a constrained system. This description, obtained without any approximation or explicit discretization, mimics features of the discrete time evolution of loop quantum cosmology. We discuss the continuum limit, physical inner product and matrix elements of physical observables to bring out various issues regarding viability of a discrete evolution. We also point out how a continuous time could emerge without appealing to any continuum limit.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this research note we introduce a new approximation of photon geodesics in Schwarzschild spacetime which is especially useful to describe highly bent trajectories, for which the angle between the initial emission position and the line of sight to the observer approaches $π$: this corresponds to the points behind the central mass of the Schwarzschild metric with respect to the observer. The approximation maintains very good accuracy overall, with deviations from the exact numerical results below $1\%$ up to the innermost stable circular orbit (ISCO) located at $6~GM/c^2$.

The nature of linguistic short-term memory and children's comprehension of spoken and written language
Creators: name: Schaefer, Heiko Ulrich
Publisher: name: Canberra, ACT : The Australian National University
Year: 1981
Subjects: subject: Short-term memory
subject: Comprehension
subject: Reading

description: Comprehension of natural language suffers at input rates above the normal speech range. If the same were true for very slow input, this would have important implications for certain types of readers. Slow reading rates exceeding the temporal capacity of a hypothesized short-term memory (STM) store, believed to play a central role in the processing of sentences, has been blamed for observed comprehension deficits in slow readers. A study involving several groups of slow-reading children showed that good comprehension can be achieved even if the hypothesized limits of the STM store are exceeded. The results of the study can be explained in terms of alternate models of sentence processing which (a) redefine the conventional view of a largely passive STM, strictly limited in capacity and function, into STM as a working space with considerable flexibility and semantic processing capability, or (b) models which are based on a more unitary view of memory and information processing with no need for a separate STM, or where something like a STM is retained but with a less crucial importance for language processing. The results also indicate that theorists and practitioners in fields outside psychology should exercise caution in extrapolating findings from experimental psychology involving atypical material and settings to tasks and situations requiring natural language processing such as in the reading and comprehension of meaningful prose in everyday life.

The emergence of the novel in modern Indonesian and Malaysian literature : a comparative study
Creators: name: Wahab, Abdul
Publisher: name: The Australian National University
Year: 1984
Subjects: subject: Indonesian fiction History and criticism
subject: Malaysian fiction History and criticism

description: The purpose of this study is to trace the emergence of the novel in the modern literature of Indonesia and Malaysia, to compare the literary backgrounds that inspired the birth of the genre, and to survey the characteristics of the early novels of each region, which resulted from their different historical backgrounds. This study begins with the fact that the emergence of the novel in the modern literature of both countries resulted from direct and continued contact between the two countries with the West. Each of the country's relations with the West was through different European powers, Indonesia with the Dutch and Malaysia with the British, and this is reflected in differences in the mode of emergence and characteristics of the early novels in both countries. Nevertheless, since the two countries were part of the Malay Archipelago and the people had a shared ethnic and cultural past, the early novels of both countries portray the same traditional influences. Since the concept of the novel was taken from the West, the study begins with a general description of the novel as understood in European literature. The study takes a historical perspective by first examining the narrative forms in the literature of the Archipelago, as represented by selected traditional Malay hikayat. The study then discusses personal contacts between local and European individuals which resulted in the emergence of a transitional prose form. The contact between locals and Europeans increased after 1824 when the Archipelago was divided into British and Dutch spheres of influence. The introduction of the printing press and the British and Dutch education systems were crucial in infleuncing the various types of prose narrative forms which preceded the novel. The study then focusses on these transitional prose forms in both the Indies and the Malay Peninsula. An analysis is made of the content and form of pre-novels and early novels in each area. The conclusion shows the similarities and differences in the nature of the birth and the form of the novel in both areas. The early novels in both the Indies and the Malay Peninsula, now known as Indonesia and Malaysia respectively, became the basis of the novels in their modern literature.
Hǒ Nansǒrhǒn and Her Hansi : a study of the life and the work of Hǒ Nansǒrhǒn, a poetess of the late sixteenth century, in Yi dynasty Korea

subject: Women poets, Chinese BiographyKorea

description: The poetess, Ho Nansorhon, lived and wrote her poetry during the reign of King Sonja. This period of the Yi dynasty witnessed the Confucianization of society to its greatest degree, with the inflexibility of the system and its concomitant sanctions severely restricting the lives of Yi dynasty women, especially warren of the yangban class, to which Nansorhon belonged. Nansorhon was born into a celebrated family of high and distinguished lineage. As a girl she was reputedly vivacious, with an obvious talent for learning the Chinese classics. She was fortunate in having gifted brothers, who later were acclaimed as being amongst the foremost writers and poets of the period. The late sixteenth century was also the golden age of hansi, a time when disillusionment with Confusian literary values emerged and the ideals of the literati-officials came under scrutiny. From this discontent, the influence of the Sung poetic convention was replaced by the T'ang poetic traditions. A group called Sam-Tang siin fully exercised the new tradition, displacing the longstanding attitude that poetry should remain as the pastime of the cultured man. This group expounded that the study and writing of poetry should exist as a lifelong discipline of writers, for whom literature must be their main concern. Importantly, one of the group, Yi Tal, was the Ho family tutor and it was he and Nansorhon's brother, Ho Pong, who significantly influenced her literary activities.

description: It is argued that a fundamental time asymmetry could arise from the global structure of the space manifold. The proposed mechanism relies on the CPT anomaly of certain chiral gauge theories defined over a multiply connected space manifold. The resulting time asymmetry (microscopic arrow of time) is illustrated by a simple thought experiment. The effect could, in principle, play a role in determining the initial conditions of the big bang.

Investigating changes in regional brain temperature in patients suffering ischaemic stroke

Subjects: Stroke

description: Stroke is a leading cause of death and disability around the world. Current acute treatments are potentially dangerous and must typically be delivered within a very limited time window to be effective. Current research into ischaemic stroke includes the search for novel therapeutic agents, as well as for techniques that may help identify patients likely to benefit from potentially dangerous therapies such as thrombolysis, or extend the time window within which these therapies are likely to be effective. Brain temperature is potentially significant in all three of these avenues of investigation. Hypothermia may be neuroprotective in its own right and may extend the time window for effective treatment with existing medications. Conversely, elevated temperature may exacerbate ischaemic injury and thus worsen a patient’s prognosis. However, measuring localised brain temperature, as opposed to body temperature, is extremely difficult. In this thesis two tools are developed with which to investigate regional brain temperature in patients suffering ischaemic stroke. A method of Magnetic Resonance Thermography (MRT), which provides a method for measuring regional brain temperature non-invasively, is developed using readily available medical imaging technology and allows estimation of temperature in healthy volunteers with an accuracy of ±1.3°C. This tool is not yet sensitive enough for routine clinical use but has the potential to be developed further. A Finite Element Model (FEM) is developed to simulate heat exchange in the stroke-affected brain. This model is validated against experimental data from the literature and is found to be valid for normal tissue, but underestimate temperature changes in ischaemic tissue. The potential implications of this finding are discussed; in particular, it appears that the changes to the process of heat exchange in ischaemic brain tissue are more complex than previously thought.
Estimating future primary school enrolments for Nepal
Creators: name: Dangol, Bishnu Dass S
Publisher: name: The Australian National University
Year: 1984
Subjects: subject: Education, Primary Nepal

description: This study identifies the Government's efforts at different points in time towards the qualitative and quantitative improvement of the Nepalese Education System. More stress is given to studying the New Education System regarding the level and organization of the system with its aims and objectives. The literacy rate, enrolment ratio, pupil-school ratio and pupil-teacher ratio have been analysed by sex and region. Nepalese education is characterised by sex and areal differentials in enrolment, literacy rate and by a high dropout rate, particularly when pupils are promoted from grade one to two. The study highlights some of the causes of such a high dropout rate. The study provides two series of projections of population from the year 1981 to 2001 at intervals of 5 years and the corresponding school age population under the plausible assumptions of fertility and mortality. Nepal's rapid population growth, inherent in the existing high fertility and declining mortality, has tended to produce more children of school age and this study tries to find out whether or not the present education system will be able to absorb the probable growth of children in the future. Because of the paucity of data on key items such as age specific enrolments and the numbers of dropouts and repeaters, future school enrolments have been estimated by adopting the ratio method rather than the cohort method. Finally the requirement for teachers and school places in the near future are considered.
Third-order structure functions for isotropic turbulence with bidirectional energy transfer

Publisher: name: arXiv
Year: 2019
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We derive and test a new heuristic theory for third-order structure functions that resolve the forcing scale in the scenario of simultaneous spectral energy transfer to both small and large scales, which can occur naturally in rotating stratified turbulence or magnetohydrodynamical~(MHD) turbulence, for example. The theory has three parameters, namely the upscale/downscale energy transfer rates and the forcing scale, and it includes the classic inertial range theories as local limits. When applied to measured data, our global-in-scale theory can deduce the energy transfer rates using the full range of data, therefore it has broader applications compared with the local theories, especially in the situations where the data is imperfect. In addition, because of the resolution of forcing scales, the new theory can detect the scales of energy input, which was impossible before. We test our new theory with a two-dimensional simulation of MHD turbulence.

description: Considering transformations in the basis of fundamental fields on a principal fiber bundle, without modification in the space-time sector, we construct an algebra GA, which we call Glashow algebra. The structure constants of this algebra depend on a mixing angle. The Lagrangian of the gauge theory of electroweak interactions without masses is obtained using a representation of GA which is the transformed of the adjoint representation of the direct product of SU(2) and U(1), and does not coincide with the adjoint representation of GA. The mixing angle is automatically present in the theory if GA is used.

Regional fertility variations in Kenya

Subjects: subject: Fertility, Human Kenya
subject: Kenya Population

description: This study is based on the Kenya Fertility Survey of 1977/78 which was carried out as part of the World Fertility Survey by the Kenyan Central Bureau of Statistics. The study had four primary objectives. First, to examine regional fertility variations in the mean number of children ever born in Kenya by five broad regions; namely Nairobi, Central/Rift valley, Coast, Nyanza/'Western and Eastern according to selected intermediate and socio-economic variables. Secondly, to examine whether fertility in Kenya would be lower in regions that are not mainly agricultural, which include, Nairobi and the Coast. Thirdly, to test the validity of any existing differentials, and to explore the factors generating such differences and the mechanisms through which these factors operate. And fourthly, to investigate the main factors that have been outlined in previous studies to be responsible for the relatively low fertility in the Coast. Fertility differentials were examined in terms of selected proximate and socio-economic factors of ever married women in five broad regions. The study also has built up "Multiple Classification Analysis (MCA)" models for the national sample and separately for the different broad regions. The descriptive analysis revealed that regional fertility variations in Kenya are limited. However, the Coast has relatively lower fertility compared to other regions. Mean number of children ever born is higher in Central/Rift Valley and Nyanza/Western regions. The MCA showed that age at first marriage is the most important factor affecting fertility in Kenya.

To calculate the local temperatures and heat currents we find the stationary state by solving a system of algebraic equations.

description: Prediction in complex systems at criticality is believed to be very difficult, if not impossible. Of particular interest is whether earthquakes, whose distribution follows a power law (Gutenberg-Richter) distribution, are in principle unpredictable. We study the predictability of event sizes in the Olmai-Feder-Christensen model at different proximities to criticality using a convolutional neural network. The distribution of event sizes satisfies a power law with a cutoff for large events. We find that prediction decreases as criticality is approached and that prediction is possible only for large, non-scaling events. Our results suggest that earthquake faults that satisfy Gutenberg-Richter scaling are difficult to forecast.

The demographic consequences of the evolution of Russian society : B.C. - 1914 A.D
Creators: name: Sherlaimoff, Tatiana
Publisher: name: The Australian National University
Year: 1979
Subjects: subject: Soviet Union Population
subject: Soviet Union History
subject: Soviet Union Social conditions

description: This thesis attempts an investigation of the demographic consequences of the changing Russian society over the period beginning with the first signs of Homo Sapiens on Russian territory to the end of the Imperial period in 1914. The aim is to discern trends in the growth and structure of the population, as well as accounting for the specific changes in the context of economic, social, political and environmental factors. The study covers the period up to the reign of Peter the Great in the second chapter, concentrating thereafter on the Imperial era, particularly the late nineteenth century. The population of St Petersburg provides an interesting case study of a major city in Imperial Russia. The major findings of the study are that Russia, more than any other country, seems to have been afflicted by a continuous cycle of harvest failure, famine, disease, epidemic, which together with constant internal struggles and wars, prevented population growth of a respectable level until the eighteenth century. The massive size of the country in the latter centuries of the study acted unfavourably on the development of the country, and therefore a hurdle to impovement in the quality of life. Russia appears to resemble the countries of today's developing world rather than the countries of Western Europe, with which it is commonly compared. This thesis does not employ any complex demographic techniques, nor any of the fashionable models of the moment. However, it does hope to present a framework for future studies of Russian historical demography and to glimpse a picture of the patterns of growth and composition of population over time. It is emphasised that the thesis takes neither a Marxist nor Imperialist line.

Self-consistent quantum-kinetic theory for interplay between pulsed-laser excitation and nonlinear carrier transport in a quantum-wire array
Creators: name: Gulley, Jeremy R.
name: Huang, Danhong
Publisher: name: arXiv

description: We propose a self-consistent many-body theory for coupling the ultrafast dipole-transition and carrier-plasma dynamics in a linear array of quantum wires with the scattering and absorption of ultrashort laser pulses. The quantum-wire non-thermal carrier occupations are further driven by an applied DC electric field along the wires in the presence of resistive forces from intrinsic phonon and Coulomb scattering of photo-excited carriers. The same strong DC field greatly modifies the non-equilibrium properties of the induced electron-hole plasma coupled to the propagating light pulse, while the induced longitudinal polarization fields of each wire significantly alters the nonlocal optical response from neighboring wires. Here, we clarify several fundamental physics issues in this laser-coupled quantum wire system, including laser influence on local transient photo-currents, photoluminescence spectra, and the effect of nonlinear transport in a micro-scale system on laser pulse propagation. Meanwhile, we also anticipate some applications from this work, such as specifying the best combination of pulse sequence through a quantum-wire array to generate a desired THz spectrum and applying ultra-fast optical modulations to nonlinear carrier transport in nanowires.
How the Geometric Calculus Resolves the Ordering Ambiguity of Quantum Theory in Curved Space

description: The long standing problem of the ordering ambiguity in the definition of the Hamilton operator for a point particle in curved space is naturally resolved by using the powerful geometric calculus based on Clifford Algebra. The momentum operator is defined to be the vector derivative (the gradient) multiplied by $-i$; it can be expanded in terms of basis vectors $γ_μ$ as $p = -i γ^μ\p_μ$. The product of two such operators is unambiguous, and such is the Hamiltonian which is just the D'Alambert operator in curved space; the curvature scalar term is not present in the Hamiltonian if we confine our consideration to scalar wave functions only. It is also shown that $p$ is Hermitian and self-adjoint operator: the presence of the basis vectors $γ^μ$ compensates the presence of $\sqrt{|g|}$ in the matrix elements and in the scalar product. The expectation value of such operator follows the classical geodetic line.

description: The geometrical picture of gauge theories must be enlarged when a gauge potential ceases to behave like a connection, as it does in electroweak interactions. When the gauge group has dimension four, the vector space isomorphism between spacetime and the gauge algebra is realized by a tetrad-like field. The object measuring the deviation from a strict bundle structure has the formal behavior of a spacetime connection, of which the deformed gauge field-strength is the torsion. A generalized derivative emerges in terms of which the two Bianchi identities are formally recovered. Effects of gravitational type turn up. The dynamical equations obtained correspond to a broken gauge model on a curved spacetime.

description: Hydra has a tubular bilayered epithelial body column with a dome-shaped head on one end and a foot on the other. Hydra lacks a permanent mouth: its head epithelium is sealed. Upon neuronal activation, a mouth opens at the apex of the head which can exceed the body column diameter in seconds, allowing Hydra to ingest prey larger than itself. While the kinematics of mouth opening are well characterized, the underlying mechanism is unknown. We show that Hydra mouth opening is generated by independent local contractions that require tissue-level coordination. We model the head epithelium as an active viscoelastic nonlinear spring network. The model reproduces the size, timescale, and symmetry of mouth opening. It shows that radial contractions, travelling inwards from the outer boundary of the head, pull the mouth open. Nonlinear elasticity makes mouth opening larger and faster, contrary to expectations. The model correctly predicts changes in mouth shape in response to external forces. By generating innervated:nerve-free chimera in experiments and simulations, we show that nearest-neighbour mechanical signalling suffices to coordinate mouth opening. Hydra mouth opening shows that in the absence of long-range chemical or neuronal signals, short-range mechanical coupling is sufficient to produce long-range order in tissue deformations.

description: We consider sufficient conditions of local removability of coincidences of maps f,g:N->M, where M,N are manifolds with dimensions dimN>dimM. The coincidence index is the only obstruction to the removability for maps with fibers either acyclic or homeomorphic to spheres of certain dimensions. We also address the normalization property of the index and coincidence-producing maps.
