description: Digital Rock Imaging is constrained by detector hardware, and a trade-off between the image field of view (FOV) and the image resolution must be made. This can be compensated for with super resolution (SR) techniques that take a wide FOV, low resolution (LR) image, and super resolve a high resolution (HR), high FOV image. The Enhanced Deep Super Resolution Generative Adversarial Network (EDSRGAN) is trained on the Deep Learning Digital Rock Super Resolution Dataset, a diverse compilation 12000 of raw and processed uCT images. The network shows comparable performance of 50% to 70% reduction in relative error over bicubic interpolation. GAN performance in recovering texture shows superior visual similarity compared to SRCNN and other methods. Difference maps indicate that the SRCNN section of the SRGAN network recovers large scale edge (grain boundaries) features while the GAN network regenerates perceptually indistinguishable high frequency texture. Network performance is generalised with augmentation, showing high adaptability to noise and blur. HR images are fed into the network, generating HR-SR images to extrapolate network performance to sub-resolution features present in the HR images themselves. Results show that under-resolution features such as dissolved minerals and thin fractures are regenerated despite the network operating outside of trained specifications. Comparison with Scanning Electron Microscope images shows details are consistent with the underlying geometry of the sample. Recovery of textures benefits the characterisation of digital rocks with a high proportion of under-resolution micro-porous features, such as carbonate and coal samples. Images that are normally constrained by the mineralogy of the rock (coal), by fast transient imaging (waterflooding), or by the energy of the source (microporosity), can be super resolved accurately for further analysis downstream.

description: Mestizos have lived on Nicaragua’s Caribbean coast since at least 1894 and been the majority group since at least 1981. However, Nicaragua’s Caribbean coast is frequently imagined as a predominantly black and indigenous space. As renewed interest in mega-development projects, such as the trans-oceanic canal, bring attention to Nicaragua’s Caribbean coast, questions about the autonomy of Afro-descendant and indigenous communities are raised once again. Moreover, as mestizos continue to migrate from the Pacific and central regions of the country towards the Caribbean coast territories, violence has escalated as they attempt to claim lands that have been constitutionally recognized as collectively owned by Afro-descendant and indigenous communities of the Caribbean coast territories. Recently, mestizos on the Caribbean coast have begun to express a racial identity, as “mestizos costeños.” This thesis explores the emergence of this racial articulation by drawing on Stuart Hall’s theory of articulation to analyze the discourses produced about mestizo costeño history and identity in Bluefields, Nicaragua. Using in-depth interviews and participant observation, this thesis examines the discursive elements that mestizos costeños link together to produce these discourses. The thesis argues that to understand how mestizos costeños fit into regional and national politics, we must explore the political work that the discursive linkages do in the articulations they produce. To that end, this thesis examines these articulations and situates them in the context of local, regional, and national politics to gain a broader understanding of the implications of the discourse of mestizo costeño identity for racial politics in Bluefields and the Caribbean coast. The thesis concludes by examining what the case of mestizos costeños in Bluefields has to offer towards understanding the contributions of identity politics to liberalism by considering the ideas of Charles Mills and Creole community leaders from Bluefields
Frequency domain descriptions of linear systems
Creators: name: Parker, Philip
Publisher: name: The Australian National University
Year: 1988
Subjects: subject: Linear systems
subject: Frequency response (Dynamics)
subject: Kalman filtering

description: This thesis begins by applying Lagrange interpolation to linear systems theory. More specifically, a stable, discrete time linear system, with transfer function G(z), is interpolated with an FIR transfer function at n equally spaced points around the unit circle. The L∞ error between the original system and the interpolation is bounded, the bound going to zero exponentially fast as n -> ∞. A similar result applies to unstable systems except that the interpolating function is a non-causal FIR transfer function . The thesis then considers Hilbert transforms from interpolation data. Given the real part of a stable transfer function evaluated at n equally spaced points around the unit circle, the Hilbert transform from interpolation data reconstructs the complete frequency response, real and imaginary parts, at all frequencies, to within a bounded L∞ error. The error bound goes to zero exponentially fast as n -> ∞. Also considered is the gain-phase problem from interpolation data. This is the same as the Hilbert transform from interpolation data, except that magnitude interpolation data instead of real part interpolation data is given. Two constructions for the gain phase problem from interpolation data are given , and L∞ error bounds derived . In both cases, the error bounds go to zero exponentially fast as n -> ∞. Application of Kalman filters to short-time Fourier analysis then follows. This contains a new method in Kalman filtering called covariance setting. The filters derived from covariance setting generalize the discrete Fourier transform. They offer a design trade-off between noise smoothing and transient response time, are recursive, and are of similar computational complexity to the discrete Fourier transform. Combining the Kalman filters for short-time Fourier analysis and Lagrange interpolation gives a new method of adaptive frequency response identification. A feature of this method is the L∞ error bound between the original system and the identified model. Using recent analysis on the inherent frequency weighting in identification algorithms shows the superiority of this new method over previous adaptive frequency response identification schemes. Finally, model reduction for unstable systems is considered. Given an unstable rational function of high McMillan degree, an approximation of lower McMillan degree, but with the same number of unstable poles, is constructed. An L∞ error bound between the original transfer function and approximation is derived. Such an approximation has application to control systems.

description: Proper graph coloring assigns different colors to adjacent vertices of the graph. Usually, the number of colors is fixed or as small as possible. Consider applications (e.g. variants of scheduling) where colors represent limited resources and graph represents conflicts, i.e., two adjacent vertices cannot obtain the same resource. In such applications, it is common that some vertices have preferred resource(s). However, unfortunately, it is not usually possible to satisfy all such preferences. The notion called flexibility was recently defined in [Dvořák, Norin, Postle: List coloring with requests, Journal of Graph Theory 2019]. There instead of satisfying all the preferences the aim is to satisfy at least a constant fraction of the request. Recently, the structural properties of planar graphs in terms of flexibility were investigated. We continue this line of research. Let G be a planar graph with a list assignment L. Suppose a preferred color is given for some of the vertices. We prove that if G is a planar graph without 4-cycles and all lists have size at least five, then there exists an L-coloring respecting at least a constant fraction of the preferences.

description: We study the decoherence process associated with the scattering of stochastic gravitational waves. We discuss the case of macroscopic systems, such as the planetary motion of the Moon around the Earth, for which gravitational scattering is found to dominate decoherence though it has a negligible influence on damping. This contrast is due to the very high effective temperature of the background of gravitational waves in our galactic environment.

Optical and X-ray studies of HEAO-1 X-ray sources

Year: 1988
Subjects: subject: X-ray sources, Galactic

description: Identifications of optical counterparts of the weaker, hard (>2 keV) HEAO-1 X-ray sources continue to be made. In this thesis results are presented of some of this work, with particular emphasis on the follow-up studies of the Galactic sources. An overview of the identification process, including the justification, aims, and methodology is given. A brief historical discussion of other X-ray surveys puts the HEAO-1 mission in perspective; it is the most recent deepest flux limited, unbiased all-sky survey in the 2-10 keV region. The importance of this survey in both the study of newly identified sources, and a wider statistical analysis of the various classes of optical counterpart is highlighted. To date there are -500 optical identifications covering all classes, from nearby stellar sources to extragalactic objects, and the projected number of identifications is expected to exceed -600 by the time the final catalog of counterparts is completed in 1990. Whereas this thesis is primarily concerned with the Galactic sources, the most populous single source of optical counterparts are the active galactic nuclei. A short presentation is given of some initial results in this area. Results of identifications of bright star counterparts, which include both the Be X-ray binary and RS Canum Venaticorum classes, are presented. For the latter it is shown that the usually variable, hard X-ray emission is likely to be a result of enhanced Solar-like flaring activity. The bulk of the work presented in this thesis is the identification and studies of X-ray emitting cataclysmic variables. Detailed optical, and some X-ray observations are presented of three such systems. One of these 1H0542-407, is shown to be a DQ Herculis (or intermediate polar) magnetic variable, with a wealth of optical and X-ray periodicities. These can be explained in terms of the orbital sidebands, with the dominant optical period arising from X-ray reprocessing on the secondary star or accretion disk bulge. Reflection of the harder X-rays (>2 keV) also occurs in this region. Radial velocity variations are seen at both the orbital and spin periods, the latter interpreted as magnetospheric disruption of the inner regions of the accretion disk. Similar velocity variations, on a longer timescale, are also seen in H0534-581, which is also proposed to be a DQ Her system, although the X-ray pulsations are much weaker. Finally the serendipitouslv discovered nova-like cataclysmic variable, LB 1800, which is identified with the transient X-ray source 4U0608-49, is discussed. This binary is a reasonably bright (V-13.5) deep eclipsing (AV-3) system with a relatively long orbital period (-5.6 h). Both the emission line and continuum eclipses have similar morphology, and in particular widths, indicating the radial extent of both emitting regions is equal.

description: The evidence base for public health decision making is limited. This research aimed to determine the strengths and limitations of evaluation practice in Australian health promotion, and identify what needs to be addressed to improve evaluation quality. Over 400 health promotion practitioners participated in interviews or surveys, and program evaluation reports were appraised. Important influences upon evaluation were identified to act within the organisation and prevention system, including leadership, culture, funding, policy and administration. There is opportunity to build evaluation capacity by addressing the pivotal determinants of health promotion evaluation, particularly in organisations that deliver programs on a smaller scale.

Subjects: subject: Inorganic Chemistry
subject: FOS: Chemical sciences

description: Brice Bosnich, an Australian inorganic chemist, graduated from the University of Sydney and obtained his PhD at the Australian National University, Canberra. He then worked successively at University College London, the University of Toronto and the University of Chicago. He had an abiding interest in stereochemistry and its relationship with chemical reactivity, and in the chirality and optical activity of coordination and organometallic complexes, mainly those of the d-block elements. His early studies concerned the topological and conformational behaviour of classical coordination compounds, mainly of cobalt(III), and made extensive use of the technique of circular dichroism. He put this background to elegant use in perhaps his most distinctive work, namely, the design and synthesis of a C2-symmetric ditertiary phosphine, (S,S)-chiraphos, the rhodium(I) complex [Rh{Ph2PCH(CH3)CH(CH3)PPh2}]+ of which catalysed efficiently the homogeneous hydrogenation of prochiral enamides to amino acids in high optical purity. Bosnich traced the high enantioselectivity to the chiral array of P-phenyl substituents that is generated on coordination of (S,S)-chiraphos. In principle, catalytic enantioselective synthesis represents a powerful and economic method of introducing chirality into the synthesis of biologically active molecules, which, since the thalidomide tragedy, are required to be marketed only in optically pure forms. Dissymmetric ligands similar to (S,S)-chiraphos are now routinely employed in this type of synthesis. Bosnich developed several other enantioselective processes based on organo-transition metal chemistry. He also had several quasi-theoretical interests, including the possible use of circular dichroism to determine the absolute configuration of chiral metal complexes, and the development of a molecular mechanics force field for metallocenes. He maintained a strong interest in the properties of multimetallic proteins and devoted much effort to the construction of chiral binucleating ligands. During the 7–8 years before his retirement from the University of Chicago in 2006, he shifted his research to supramolecular recognition by suitably designed metal complexes.

description: Background Adoptive T-cell transfer has become an attractive therapeutic approach for hematological malignancies but shows poor activity against large and heterogeneous solid tumors. Interleukin-12 (IL-12) exhibits potent antitumor efficacy against solid tumors, but its clinical application has been stalled because of toxicity. Here, we aimed to develop a safe approach to IL-12 T-cell therapy for eliminating large solid tumors. Methods We generated a cell membrane-Anchored IL-12 (aIL12), a tumor-Targeted IL-12 (ttIL12), and a cell membrane-Anchored and ttIL-12 (attIL12) and a cell membrane-Anchored and tumor-Targeted ttIL-12 (attIL12) armed T cells, chimeric antigen receptor-T cells, and T cell receptor-T (TCR-T) cells with each. We compared the safety and efficacy of these armed T cells in treating osteosarcoma patient-derived xenograft tumors and mouse melanoma tumors after intravenous infusions of the armed T cells. Results attIL12-T cell infusion showed remarkable antitumor efficacy in human and mouse large solid tumor models. Mechanistically, attIL12-T cells targeted tumor cells expressing cell-surface vimentin, enriching effector T cell and interferon γproduction in tumors, which in turn stimulates dendritic cell maturation for activating secondary T-cell responses and tumor antigen spreading. Both attIL12-and aIL12-T-cell transfer eliminated peripheral cytokine release and the associated toxic effects. Conclusions This novel approach sheds light on the safe application of IL-12-based T-cell therapy for large and heterogeneous solid tumors.
Mochtar Lubis : author, editor, political actor
Creators: name: Hill, David T.
Publisher: name: The Australian National University
Year: 1988

description: This thesis is a biographical study of the Indonesian author and journalist, Mochtar Lubis (from his birth in 1922, to 1982, when he turned 60), examining the nexus between journalism, fiction and politics in his life. It sees Mochtar Lubis as a prism, through which one can view his various milieux -- intellectual, artistic, journalistic and political -- and the national history of the times through which he has lived. Mochtar Lubis has been Indonesia's best known journalist internationally and was for a long time the country's most translated author. This study aims to contribute to our general understanding of the socio-political roles of intellectuals like Mochtar Lubis, in Indonesia in the first instance, but also, by extension, in other Southeast Asian countries. The thesis has been influenced primarily by two main bodies of academic writing: firstly, an ongoing debate regarding the relationship between literature and politics; and, secondly, discussions of the role of Indonesian political intellectuals described variously as secular, liberal, modernising or Westernised. After detailing Mochtar Lubis's early life, the thesis follows his career as a journalist and political activist since 1949. Chief concerns are the political characteristics of Mochtar Lubis as editor of the daily newspaper Indonesia Raya in two periods: 1949-58 and 1968-74. The circumstances leading to his detentions in December 1956 and again in February 1975, and the paper's subsequent closures are examined, as are Mochtar Lubis's responses to his arrests. Attention is given to his move away from political journalism, after 1975, towards cultural and sociological writings, as part of his increasing international activities. The development of his reputation as an author and cultural figure is discussed with reference to the Indonesian cultural politics since 1949. After 1966, Mochtar Lubis has been involved in some of the principal institutions of the national artisitc Establishment as well as various international organisations. Critiques of Mochtar's novels and a major public lecture follow, with emphasis on the insight they provide into his attitudes to his society, its history and its structure. The thesis concludes by locating Mochtar Lubis within his social and political context, with reference to the assessments of other Indonesians and comparisons with his peers, and by reviewing the qualities he has displayed during his political career.

description: A $(0,1)$-matrix has the Consecutive Ones Property (C1P) for the rows if there is a permutation of its columns such that the ones in each row appear consecutively. We say a $(0, 1)$-matrix is nested if it has the consecutive ones property for the rows (C1P) and every two rows are either disjoint or nested. We say a $(0, 1)$-matrix is 2-nested if it has the C1P and admits a partition of its rows into two sets such that the submatrix induced by each of these sets is nested. We say a split graph $G$ with split partition $(K, S)$ is nested (resp.\ 2-nested) if the matrix $A(S, K)$ which indicates the adjacency between vertices in $S$ and $K$ is nested (resp.\ 2-nested). In this work, we characterize nested and 2-nested matrices by minimal forbidden submatrices. This characterization leads to a minimal forbidden induced subgraph characterization for these classes of graphs, which are a superclass of threshold graphs and a subclass of split and circle graphs.

description: The use of the osmotic thermodynamic model, combined with a series of methane and carbon dioxide gas adsorption experiments at various temperatures, has allowed shedding some new light on the fascinating phase behavior of flexible MIL-53(Al) metal-organic frameworks. A generic temperature-loading phase diagram has been derived; it is shown that the breathing effect in MIL-53 is a very general phenomenon, which should be observed in a limited temperature range regardless of the guest molecule. In addition, the previously proposed stress model for the structural transitions of MIL-53 is shown to be transferable from xenon to methane adsorption. The stress model also provides a theoretical framework for understanding the existence of lp/np phase mixtures at pressures close to the breathing transition pressure, without having to invoke an inhomogeneous distribution of the adsorbate in the porous sample.

description: Colleagues often refer to Alan Walker as the Eric Clapton (one of the most influential musicians of the late twentieth century) of palaeoanthropology in recognition of the artistry of his science. His field discoveries filled major gaps in our knowledge of primate evolution, such as elucidating the Miocene world of Proconsul and finding the transitional ‘Black Skull’ of Australopithecus aethiopicus and the skeleton of a Homo erectus boy. In addition to discovering these remarkable fossils, Alan was essential in bringing a palaeobiological approach to the laboratory interpretation of their bony morphology. He used the relationships between form and function in living species as a baseline for understanding the past, he pioneered dental microwear analysis to infer diet and was an early-adopter of the use of microCT to explore the internal structure of primate ear bones. Beyond these scientific accomplishments, however, it was Alan's grace and generosity that truly set him apart from his peers. As the patriarch of an extensive intellectual family of students, postdocs and colleagues, Alan taught by example how to be intellectually creative, brave, meticulous, generous and kind. His legacy will long be felt in both the science and the culture of palaeoanthropology.

description: Mobile Crowd-Sensing (MCS) has appeared as a prospective solution for large-scale data collection, leveraging built-in sensors and social applications in mobile devices that enables a variety of Internet of Things (IoT) services. However, the human involvement in MCS results in a high possibility for unintentionally contributing corrupted and falsified data or intentionally spreading disinformation for malevolent purposes, consequently undermining IoT services. Therefore, recruiting trustworthy contributors plays a crucial role in collecting high-quality data and providing better quality of services while minimizing the vulnerabilities and risks to MCS systems. In this article, a novel trust model called Experience-Reputation (E-R) is proposed for evaluating trust relationships between any two mobile device users in a MCS platform. To enable the E-R model, virtual interactions among the users are manipulated by considering an assessment of the quality of contributed data from such users. Based on these interactions, two indicators of trust called Experience and Reputation are calculated accordingly. By incorporating the Experience and Reputation trust indicators (TIs), trust relationships between the users are established, evaluated and maintained. Based on these trust relationships, a novel trust-based recruitment scheme is carried out for selecting the most trustworthy MCS users to contribute to data sensing tasks. In order to evaluate the performance and effectiveness of the proposed trust-based mechanism as well as the E-R trust model, we deploy several recruitment schemes in a MCS testbed which consists of both normal and malicious users. The results highlight the strength of the trust-based scheme as it delivers better quality for MCS services while being able to detect malicious users.

Accretion processes in AM Herculis systems

description: We begin by presenting a theoretical model for the radial velocity and velocity dispersion of the broad emission line component in AM Herculis systems assuming that it originates mainly in the gas which is diverted out of the orbital plane and funneled on to the white dwarf surface along magnetic field lines. The model is used to locate the line forming region in three AM Her variables using as constraints the radial velocity and velocity dispersion data. This work shows that the material is threaded by the magnetic field in a very azimuthally extended coupling region located 0.5 - 0. 75 of the way between the white dwarf and the inner Lagrange point. This implies that the cyclotron emission region on the stellar surface is extended, probably arc-shaped, and offset from the magnetic pole. Models for cylindrically extended and arc-shaped cyclotron emission regions displaced from the magnetic poles are then generated, taking into account the effects of field spread across the shock. The properties of cylindrically extended models with density and temperature structure and geometrical extension are also investigated. These models are an improvement on previous point source models and have characteristics that are in better overall agreement with the properties of AM Herculis systems. Phas dependent spectropolarimetric observations of VV Puppis which show, for the first time, cyclotron lines from both poles are presented. The rnain and secondary emission regions have fields of 30.5 MG and 56 MG respectively. The observations have been interpreted in terms of a dipole which is offset by ~ 0.1 white dwarf radii from the center of the star in the direction of the dipole axis with the emission regions located near the foot points of closed field lines. Spectroscopic and circular polarization observations of the soft X-ray clipsing binary EXO 033319 - 2554.2 which confirm it as a member of the AM Herculis class are presented. Broad resolvable and variable cyclotron harmonics from both poles are seen during the bright phase corresponding to magn tic fields of 56 MG (main region) and 28 MG (secondary region). As is the case for VV Puppis, the large difference in magnetic field str ngth of the two regions implies a more complex field structure than that of a cent red dipole field distribution, if it is assumed that the regions are connected by closed field lines. U BV RI and long term plate photometry of the faint and highly erratic cataclysmic variable discovered from a sequence of UK Schmidt measurements are presented. We show that this object ( designated Grus Vl) is almost certainly a new AM Herculis variable, and develop a model in which the light curves are explained as originating from two nonpolar cyclotron em1ss1on regions.

description: On any compact Riemannian manifold $(M, g)$ of dimension $n$, the $L^2$-normalized eigenfunctions $\{ϕ_λ\}$ satisfy $||ϕ_λ||_{\infty} \leq C λ^{\frac{n-1}{2}}$ where $-Δϕ_λ = λ^2 ϕ_λ.$ The bound is sharp in the class of all $(M, g)$ since it is obtained by zonal spherical harmonics on the standard $n$-sphere $S^n$. But of course, it is not sharp for many Riemannian manifolds, e.g. flat tori $\R^n/Γ$. We say that $S^n$, but not $\R^n/Γ$, is a Riemannian manifold with maximal eigenfunction growth. The problem which motivates this paper is to determine the $(M, g)$ with maximal eigenfunction growth. Our main result is that such an $(M, g)$ must have a point $x$ where the set ${\mathcal L}_x$ of geodesic loops at $x$ has positive measure in $S^*_x M$. We show that if $(M, g)$ is real analytic, this puts topological restrictions on $M$, e.g. only $M = S^2$ (topologically) in dimension 2 can possess a real analytic metric of maximal eigenfunction growth. We further show that generic metrics on any $M$ fail to have maximal eigenfunction growth. In addition, we construct an example of $(M, g)$ for which ${\mathcal L}_x$ has positive measure for an open set of $x$ but which does not have maximal eigenfunction growth, thus disproving a naive converse to the main result.

Nonlinear second order elliptic equations with Venttsel boundary conditions

Subjects: subject: Boundary value problems

description: This thesis is concerned with second order elliptic equations with cenain second order boundary conditions which are called Venttsel boundary conditions. This sort of boundary condition originally came from probability theory. An example of such a boundary value problem of PDE also arises from a model in three dimensional water wave theory. Venttsel boundary conditions contain Dirichlet, Neumann, oblique and mixed boundary conditions as special cases, and from the probability point of view they are the most general admissible boundary conditions for second order elliptic operators.
Adsorption of interacting self-avoiding trails in two dimensions

description: We investigate the surface adsorption transition of interacting self-avoiding square lattice trails onto a straight boundary line. The character of this adsorption transition depends on the strength of the bulk interaction, which induces a collapse transition of the trails from a swollen to a collapsed phase, separated by a critical state. If the trail is in the critical state, the universality class of the adsorption transition changes; this is known as the special adsorption point. Using flatPERM, a stochastic growth Monte Carlo algorithm, we simulate the adsorption of self-avoiding interacting trails on the square lattice using three different boundary scenarios which differ with respect to the orientation of the boundary and the type of surface interaction. We confirm the expected phase diagram, showing swollen, collapsed, and adsorbed phases in all three scenarios, and confirm universality of the normal adsorption transition at low values of the bulk interaction strength. Intriguingly, we cannot confirm universality of the special adsorption transition. We find different values for the exponents; the most likely explanation is that this is due to the presence of strong corrections to scaling at this point.

description: We present a new class of hermitian one-matrix models originated in the W-infinity algebra: more precisely, the polynomials defining the W-infinity generators in their fermionic bilinear form are shown to expand the orthogonal basis of a class of random hermitian matrix models. The corresponding potentials are given, and the thermodynamic limit interpreted in terms of a simple plasma picture. The new matrix models can be successfully applied to the full bosonization of interesting one-dimensional systems, including all the perturbative orders in the inverse size of the system. As a simple application, we present the all-order bosonization of the free fermionic field on the one-dimensional lattice.

The Aboriginal population of Alice Springs : a demographic study

description: Our knowledge of Aboriginal demography in Australia at a national level is limited by the lack of conformity of the census counts on the size of the population and the unavailability of vital data. Hence, regional and small area studies were found useful to reveal the recent patterns of Aboriginal demography. This study begins with a review of Aboriginal demography at a national level. The distinct demographic characteristics of the Aboriginal population are pointed out in comparison with the total population of the country. The study then focuses on a regional level, Central Australia, for a closer examination of mortality and fertility levels, patterns, trends and differentials. It confirms that the levels of Aboriginal mortality and fertility in Central Australia are substantially higher than those of the total population of the country and are similar to those found for the Aboriginal population elsewhere; however, it registers, for the first time through a single study on a particular population, the occurrence of a process of steady decline in Aboriginal mortality and establishes that this decline in mortality is largely due to the reduction in deaths from diseases of the circulatory and respiratory systems, which are in the meantime still the leading causes of death of the Aboriginal people. Aboriginal fertility was found to be very high in the early ages of childbearing and the observed decline is mostly due to the reduction of fertility of the older women of 30 and over and younger women of 15-19. A detailed study of the demographic characteristics of the Aboriginal population in Alice Springs revealed that while as a whole the characteristics of Alice Springs Aborigines are similar to those of Aborigines elsewhere, different patterns of socio-economic and historical conditions have led to the emergence of two demographically distinct Aboriginal groups in Alice Springs; those Aborigines who live in the town proper and those who live in the town camps. While the majority of those Aborigines who migrated to the town proper came from other urban centres, most of the town campers are rural-urban migrants mostly from ether Aboriginal settlements and stations in Central Australia.
Alternatively spliced variants of the 5’-UTR of the ARPC2 mRNA regulate translation by an internal ribosome entry site (IRES) harboring a guanine-quadruplex motif

description: The 5ʹ-UTR of the actin-related protein 2/3 complex subunit 2 (ARPC2) mRNA exists in two variants. Using a bicistronic reporter construct, the present study demonstrates that the longer variant of the 5ʹ-UTR harbours an internal ribosome entry site (IRES) which is lacking in the shorter one. Multiple control assays confirmed that only this variant promotes cap-independent translation. Furthermore, it includes a guanine-rich region that is capable of forming a guanine-quadruplex (G-quadruplex) structure which was found to contribute to the IRES activity. To investigate the cellular function of the IRES element, we determined the expression level of ARPC2 at various cell densities. At high cell density, the relative ARPC2 protein level increases, supporting the presumed function of IRES elements in driving the expression of certain genes under stressful conditions that compromise cap-dependent translation. Based on chemical probing experiments and computer-based predictions, we propose a structural model of the IRES element, which includes the G-quadruplex motif exposed from the central stem-loop element. Taken together, our study describes the functional relevance of two alternative 5ʹ-UTR splice variants of the ARPC2 mRNA, one of which contains an IRES element with a G-quadruplex as a central motif, promoting translation under stressful cellular conditions
