Genetic association studies have identified 44 common genome-wide significant risk loci for late-onset Alzheimer's disease (LOAD). However, LOAD genetic architecture and prediction are unclear. Here we estimate the optimal P-threshold (P
The Australian Imaging, Biomarkers and Lifestyle (AIBL) Study commenced in 2006 as a prospective study of 1,112 individuals (768 cognitively normal (CN), 133 with mild cognitive impairment (MCI), 211 Alzheimer's disease dementia (AD)) an 'Inception cohort' who underwent detailed ssessments every 18 months. Over the past decade, additional 1247 subjects have been added 'Enrichment (as 10 April 2019). Here we provide overview these Inception Enrichment cohorts more than 8,500 person-years...
Aging and Alzheimer's disease (AD) are associated with progressive brain disorganization. Although structural asymmetry is an organizing feature of the cerebral cortex it unknown whether continuous age- AD-related cortical degradation alters asymmetry. Here, in multiple longitudinal adult lifespan cohorts we show that higher-order regions exhibiting pronounced at age ~20 also asymmetry-loss across lifespan. Hence, accelerated thinning (previously) thicker homotopic hemisphere a aging. This...
Camera tracking is a fundamental requirement for video-based augmented reality applications. The ability to accurately calculate the intrinsic and extrinsic camera parameters each frame of video sequence essential if synthetic objects are be integrated into image data in believable way. In this paper, we present an accurate reliable approach calibration off-line We first describe improved feature algorithm, based on widely used Kanade-Lucas-Tomasi tracker. Estimates inter-frame motion guide...
Abstract Generating accurate radiosity solutions of very complex environments is a time‐consuming problem. We present rapid hierarchical algorithm that enables such to be computed quickly and efficiently. Firstly, new technique for bounding the error in transfer between surfaces discussed, incorporating bounds on form factors, visibility, irradiance, reflectance over textured surfaces. This then applied problem clusters surfaces, leading fast, practical clustering builds previous work...
This paper describes a publicly available virtual reality (VR) system, GNU/MAVERIK, which forms one component of complete 'VR operating system'. We give an overview the architecture MAVERIK, and show how it is designed to use application data in intelligent way, via simple, yet powerful, callback mechanism supports object-oriented framework classes, objects methods. Examples are given illustrate different uses typical performance levels.
We propose a new algorithm that uses consumer-level graphics hardware to render shadows cast by synthetic objects and real lighting environment. This has immediate benefit for interactive Augmented Reality applications, where must be accurately merged with images. show how soft direct indirect illumination sources may generated composited into background image at rates. describe the of light (and hence shadow) affecting each point in an can efficiently encoded using hierarchical shaft-based...
Clinical research studies offer many challenges for their supporting information systems. AIBL assembled 1112 participants who volunteered crucial a comprehensive study on neurodegenerative diseases. This paper discusses the shortcomings of clinical trial management system chosen to record results study. A set guidelines was devised and critique five systems ensued. OpenClinica selected as most appropriate option. The main contribution this is: (i) proposing determine appropriateness Trial...
Abstract Alzheimer’s Disease (AD) is the most common form of dementia, characterised by extracellular amyloid deposition as plaques and intracellular neurofibrillary tangles tau protein. As no current clinical test can diagnose individuals at risk developing AD, aim this project to evaluate a blood-based biomarker panel identify who carry risk. We analysed levels 22 biomarkers in clinically classified healthy controls (HC), mild cognitive impairment (MCI) participants from well Australian...
We present a new approach to radiosity simulation that uses perceptually‐based measures control the generation of view‐independent solutions. This enables computational effort be moved away from areas are deemed have visually insignificant effect on solution's appearance, into those more noticeable. achieve this with an a‐priori estimate real‐world adaptation luminance, and use tone‐reproduction operator transform luminance values display colours during solution process. The distance between...

Photometric reconstruction is the process of estimating illumination and surface reflectance properties an environment, given a geometric model scene set photographs its surfaces. For mixed-reality applications, such data required if synthetic objects are to be correctly illuminated or light sources used re-light scene. Current methods limited in practical situations which they can applied, due fact that radiometric models provided by user must complete, position (and some cases, intensity)...
There are many real-world applications of Virtual Reality that require the construction complex and accurate three-dimensional models, suitably structured for interactive manipulation. In this paper, we present semi-automatic methods allow such environments to be quickly easily built from photographs taken with uncalibrated cameras, illustrate techniques by application problem scene-of-crime reconstruction.
A large scale, long term clinical study faced significant quality issues with its medications use data which had been collected from participants using paper forms and manually entered into a capture system. method was developed that automatically mapped 72.2% of the unique medication names for to AMT SNOMED CT-AU Ontoserver, terminology server ontologies. These initial results are promising and, further improvements algorithms evaluation, expected greatly improve analysis gathered study.
We report a qualitative study of navigation, wayfinding, and place experience within virtual city. “Cityscape” is environment (VE), partially algorithmically generated intended to be redolent the aggregate forms real cities. In present study, we observed interviewed participants during following exploration desktop implementation Cityscape. A number emergent themes were identified are presented discussed. Observing interaction with city suggested continuous relationship between worlds....
