description: The research of the authors investigates an alternative interface for Instant Messaging (IM). This paper presents SWIM (SWinburne Instant Messaging), an IM tool that is developed based on MSN Messenger. SWIM presents an innovative interface design that combines the conventional sequential interface with the adaptive threaded interface. In addition, SWIM supports persistent conversation which facilitates users' participation to a group conversation. The integrated interface and support for persistent conversation allow SWIM to be used both as a convenient tool for social conversation and as an effective tool for task-oriented group discussion. In this paper, we discuss the design approach of SWIM, describe details of our implementation technique, and report a preliminary evaluation of SWIM. The evaluation shows that SWIM holds great promise in supporting group conversation.

description: Despite considerable efforts, our understanding of the organization of higher order chromatin conformations in single cells and how these relate to chromatin marks remains poor. We have earlier invented the Chromatin In Situ Proximity (ChrISP) technique to determine proximities between chromatin fibers within a single chromosome. Here we used ChrISP to identify chromosome 11-specific hubs that are enriched in the H3K9me2 mark and that project toward the nuclear membrane in finger-like structures. Conversely, chromosome 11-specfic chromatin hubs, visualized by the presence of either H3K9me1 or H3K9me3 marks, are chromosome-wide and largely absent at the nuclear periphery. As the nuclear periphery-specific chromatin hubs were lost in the induced reduction of H3K9me2 levels, they likely represent Large Organization Chromatin in Lysine Methylation (LOCK) domains, previously identified by ChIP-seq analysis. Strikingly, the downregulation of the H3K9me2/3 marks also led to the chromosome-wide compaction of chromosome 11, suggesting a pleiotropic function of these features not recognized before. The ChrISP-mediated visualization of dynamic chromatin states in single cells thus provides an analysis of chromatin structures with a resolution far exceeding that of any other light microscopic technique.

description: This paper summarizes present knowledge of the synanthropic nitrophilous communities dominated by tall herbs on the basis of the present Artemisietea vulgaris database. Floristic variability was examined also in detrended correspondence analysis. Each cluster was inspected for its ecological and floristic consistency. The final interpretable solution comprises five clusters. Species to clusters fidelity was calculated using ϕ coefficient. The ecological interpretation of the five groups was based on the average Pignatti indicator values. Groups were compared by using Tukey's honest significant difference test in conjunction with ANOVA. Finally, based on the statistical analysis, we established five alliances: Onopordionacanthii, Matricario-Chenopodion, Dauco-Melilotion, Arctionlappae, and Convolvuloarvensis-Elytrigionrepenti.

WAVELET ANALYSIS
official statistics

description: This thesis examines the issue of detecting components or features within time series data in automatic procedures. We begin by introducing the concept of Wavelets and briefly show their usage as a tool for detection. This leads to our first contribution which is a novel method using wavelets for identifying correlation structures in time series data which are often ambiguous with very different contexts. Using the properties of the wavelet transform we show the ability to distinguish between short memory models with changepoints and long memory models. The next two Chapters consider seasonality within data, which is often present in time series used in Offical Statistics. We first describe the historical evolution of identification of seasonality, comparing and contrasting methodology as it has expanded throughout time. Following this, motivated by the increased use of high-frequency time series in Official Statistics and a lack of methods for identifying low-frequency seasonal components within high-frequency data, we present a method for identifying periodicity in a series with the use of a simple wavelet decomposition. Presented with theoretical results and simulations, we show how the seasonality of a series is uniquely represented within a wavelet transform and use this to identify low frequency components which are often overlooked in favour of a trend, with very different interpretations. Finally, beginning with the motivation of forecasting European Area GDP at the current time point, we show the effectiveness of an algorithm which detects the most useful data and structures for a Dynamic Factor Model. We show its effectiveness in reducing forecasting errors but show that under large scale simulation that the recovery of the true structure over two dimensions is a difficult task. All the chapters of this thesis are motivated by, and give applications to, time series from different areas of Official Statistics.

description: Observing System Simulated Experiments (OSSEs) performed during the 2014 North Atlantic hurricane season quantify ocean observing system impacts with respect to improving ocean model initialisation in coupled tropical cyclone (TC) prediction systems. The suitability of the OSSE system forecast model (FM) with respect to the previously validated Nature Run is demonstrated first. Analyses are then performed to determine the calibration required to obtain credible OSSE impact assessments. Impacts on errors and biases in fields important to TC prediction are first quantified for three major components of the existing operational ocean observing system. Satellite altimetry provides the greatest positive impact, followed by Argo floats and sea surface temperature measurements from both satellite and in-situ systems. The OSSE system is then used to investigate observing system enhancements, specifically regional underwater glider deployments during the 2014 hurricane season. These deployments resulted in modest positive impacts on ocean analyses that were limited by (1) errors in the horizontal structure of the increment field imposed by individual gliders and (2) memory loss in the spreading of these corrections by nonlinear model dynamics. The high-resolution, threedimensional representation of the truth available in OSSE systems allows these issues to be studied without high-density ocean observations.

description: This paper presents the construction and locomotion analysis of the modular robots composed of expandable cubes (E-Cubes). The kinematic properties and experiment research of the assembled modular robots are the main focus of the paper. The E-Cube consisted of only prismatic joints is a cubic module with three degrees of freedom corresponding to three mutually perpendicular directions. The modular robots are constructed by connecting the vertex or edge of the adjacent modules. In this paper, first, the modular robot system including the E-Cube hardware, connection method of modules and a potential binary control strategy is described. And then, the detailed kinematics, stability and motion simulations of three configurations assembled with four modules are analysed. After that, a set of experimental pneumatic-based robotic system is built. At last, the gait experiments of the configurations are carried out to testify the feasibility and validity of design and locomotion functions. The experiment results show the reliability of the mechanical, control and pneumatic systems and the programming and control efficiency of the binary control strategy. As extension, a modular robot with eight modules is assembled, and its different locomotion gaits are simulated accordingly.

description: Neurons communicate via chemical signals called neurotransmitters (NTs). The numerous identified NTs can have very different physiochemical properties (solubility, charge, size etc.), so quantification of the various NT classes traditionally requires several analytical platforms/methodologies. We here report that a diverse range of NTs (e.g. peptides oxytocin and vasopressin, monoamines adrenaline and serotonin, and amino acid GABA) can be simultaneously identified/measured in small samples, using an analytical platform based on Hydrophilic Interaction Liquid Chromatography (HILIC) and high-resolution mass spectrometry (MS).
The highly automated platform is cost-efficient as manual sample preparation steps and one-time-use equipment are kept to a minimum. Zwitter-ionic HILIC stationary phases were used for both on-line solid phase extraction (SPE) and capillary liquid chromatography (cLC); enabling compounds from all NT classes to elute in small volumes producing sharp and symmetric signals, and allowing precise quantifications of small samples (demonstrated with whole blood, 100 microliters per sample). An additional robustness-enhancing feature is automatic filtration/filter back-flushing (AFFL), allowing hundreds of samples to be analyzed without any parts needing replacement (due to e.g. clogged SPE or LC columns).
The platform can be installed by simple modification of a conventional LC-MS system, requiring one additional LC pump and one additional switching valve.

description: This paper describes an experimental study focusing onto the way drivers use the steering wheel while performing a 2D tracking task. The stimulus during this task was a steering wheel angle signal recorded in real situations involving turns and straight lines performed at about 30 km/h. The hand positions of 20 volunteers were recorded in 6 steering scenarios involving 7 road geometries using a 3D motion capture system. The hand movement data were analysed via a descriptive/inferential procedure: each hand was considered using nine indicators – eight membership value averages linked to eight fuzzy angle windows and a frequency value related to the off steering wheel position – while the indicators were investigated using multiple correspondence analysis and non-parametric global and post-hoc tests. Results showed that inter-individual differences were larger than intra-individual differences. Considering 2 × 9 = 18 windows, the inter-individual differences mainly appeared during two main kinds of steering hand strategies: with versus without crossing hands, the latter being the most often used (17 among 20 participants). The intra-individual data showed that some drivers maintained a nearly identical strategy for all road geometries, while other drivers changed their hand position with the direction and/or maximum angle value of the turn.

description: Expected daily FL ranges (length at date) of juvenile Chinook Salmon Oncorhynchus tshawytscha have been used throughout California's Central Valley to identify federally listed winter-run and spring-run juveniles in a mixed four-race stock. Accurate race identification is critical both to species recovery and to management of the water supply for 25 million people and a multibillion-dollar agricultural industry. We used genetic race assignment of 11,609 juveniles sampled over 6 years to characterize the accuracy of the length-at-date approach, specifically by testing two of its central assumptions: (1) juvenile FL distributions do not overlap between races on a daily basis; and (2) the growth rates that are used to project FL at date are accurate. We found that 49% of FLs for genetically identified juveniles occurred outside the expected length-at-date ranges for their respective races, and we observed a high degree of overlap in FL ranges among the four races. In addition, empirical growth rates were well below those from which length-at-date criteria were derived. Given the high degree of FL overlap between races, we conclude that modification of the length-at-date method will not substantially reduce identification error. Thus, we recommend that genetic assignment be used at least as a supplemental approach to improve Central Valley Chinook Salmon race identification, research, and management.Received January 7, 2014; accepted July 22, 2014

description: Autophagy is a bulky catabolic process that responds to nutrient homeostasis and extracellular stress signals and is a conserved mechanism in all eukaryotes. When autophagy is induced, cellular components are sequestered within an autophagosome and finally degraded by subsequent fusion with a lysosome. During this process, the ATG12–ATG5 conjugate requires 2 different binding partners, ATG16L1 for autophagosome elongation and TECPR1 for lysosomal fusion. In our current study, we describe the crystal structures of human ATG5 in complex with an N-terminal domain of ATG16L1 as well as an internal AIR domain of TECPR1. Both binding partners exhibit a similar α-helical structure containing a conserved binding motif termed AFIM. Furthermore, we characterize the critical role of the C-terminal unstructured region of the AIR domain of TECPR1. These findings are further confirmed by biochemical and cell biological analyses. These results provide new insights into the molecular details of the autophagosome maturation process, from its elongation to its fusion with a lysosome.

description: In this thesis, I have described the way in which doctors represented Aboriginal and Torres Strait Islander people in Australian medical journals. I have concentrated on publications in the Medical Journal of Australia before 1970. Such medical representations influenced not only the way doctors reading these journals thought about Indigenous people but continue to influence how all Australians, Indigenous and non-Indigenous, think about Indigenous people and their health. I have explored the researchers' changing ways of writing about race and the ambiguities of how they described Indigenous Australians as sometimes different from and sometimes the same as settler Australians. In contrast to many researchers' views of science as objective, it has been possible to see how this research was influenced by broader social and political forces: from the colonial drive to settle northern Australia, through the changing politics of race, to the dramatic changes in Australian society and Indigenous politics at the end of the 1960s. I also used the medical journals to begin to describe how research was performed in this colonial setting. Many of the researchers, such as John Burton Cleland from Adelaide University, wrote that Aboriginal people passively and powerlessly cooperated with their research. It has been possible to read the accounts written by Cleland and other researchers and begin to see the constrained agency of these same Aboriginal people with their considered participation given in exchange for material goods, medical care and entertainment. The researchers attempted to influence this exchange by using their more powerful political position in the colonial encounter and occasionally deceit. The conclusion describes the implications of this history for present-day Indigenous health research. I encourage the writers of this research to more explicitly acknowledge the historical and political context of their medical research.

description: “Input uncertainty” refers to the (often unmeasured) variability in simulation-based performance estimators that is a consequence of driving the simulation with input models (e.g., fully specified univariate distributions of i.i.d. inputs) that are based on real-world data. In 2012 Ankenman and Nelson presented a quick-and-easy diagnostic experiment to assess the overall effect of input uncertainty on simulation output. When their method reveals that input uncertainty is substantial, then the natural next questions are which input distributions contribute the most to input uncertainty, and from which input distributions would it be most beneficial to collect more data? They proposed a possibly lengthy sequence of additional diagnostic experiments to answer these questions. In this paper we provide a method that obtains an estimator of the overall variance due to input uncertainty, the relative contribution to this variance of each input distribution, and a measure of the sensitivity of overall uncertainty to increasing the real-world sample-size used to fit each distribution, all from a single diagnostic experiment. Our approach exploits a metamodel that relates the means and variances of the input distributions to the mean response of the simulation output, and bootstrapping of the real-world data to represent input-model uncertainty. Further, we investigate whether and how the simulation outputs from the nominal and diagnostic experiments may be combined to obtain a better performance estimator. For the case when the analyst obtains additional real-world data, refines the input models, and runs a follow-up experiment, we analyze whether and how the simulation outputs from all three experiments should be combined. Numerical illustrations are provided.

description: We have investigated the effect of magnetic processing on orientation of gold nanowires (AuNWs) using a strong magnetic field. The results in the extinction spectra due to surface plasmon and SEM images in the presence of magnetic processing (10 T) showed that the long axes of AuNWs in side-by-side aggregation of AuNWs were oriented perpendicular to the magnetic field. On the other hand, in the absence of magnetic processing, random orientation of the side-by-side aggregation of AuNWs was observed. The magnetic orientation of the aggregation is most likely attributable to the anisotropy in the magnetic susceptibilities of the pristine AuNWs.

description: A gold nanoparticle (AuNP)–supported gadolinium complex (RS-Au-L-Gd) catalyst was prepared through simple chelation of GdCl3 to the surface-bound spacer, 1,4,7-tris(carboxymethyl)-10-(11-mercaptoundecyl)-1,4,7,10-tetraazacyclododecane (HSDO3A). This AuNP-supported Gd complex was found to be a highly effective catalyst for the acetylation of various alcohols and phenol in the presence of acetic anhydride. With a loading of 0.4 mol% of RS-Au-L-Gd, the almost complete transformation can be achieved in 60 s under microwave irradiation conditions. This hybrid catalyst was air stable, water soluble, dissolvable in many organic media, and precipitable. It can be readily recycled more than eight times without any significant loss of its catalytic activity.

description: Postures and muscle activity in the upper body were recorded from 50 academics office workers during 2 hours of normal work, categorised by observation into computer work (CW) and three non-computer (NC) tasks (NC seated work, NC standing/walking work and breaks). NC tasks differed significantly in exposures from CW, with standing/walking NC tasks representing the largest contrasts for most of the exposure variables. For the majority of workers, exposure variability was larger in their present job than in CW alone, as measured by the job variance ratio (JVR), i.e. the ratio between min–min variabilities in the job and in CW. Calculations of JVRs for simulated jobs containing different proportions of CW showed that variability could, indeed, be increased by redistributing available tasks, but that substantial increases could only be achieved by introducing more vigorous tasks in the job, in casu illustrated by cleaning.
