Summary
Measuring interference from prior memories using experience sampling. The project aims to better understand the causes of forgetting in recognition memory. This project will measure participants' experiences using smartphone technology for four weeks before a recognition memory experiment. Similarities between the images in the experiment and images in prior experience can be used to fully specify all interference components within a computational model of recognition memory, leading to a comple ....Measuring interference from prior memories using experience sampling. The project aims to better understand the causes of forgetting in recognition memory. This project will measure participants' experiences using smartphone technology for four weeks before a recognition memory experiment. Similarities between the images in the experiment and images in prior experience can be used to fully specify all interference components within a computational model of recognition memory, leading to a complete model of recognition memory. Better understanding the causes of forgetting in recognition memory could show how interference contributes to memory impairments in ageing, and ultimately Alzheimer’s and other clinical disorders.Read moreRead less

In particular an exciting new class of methods whose computational cost scales linearly with system size. Our goal is to develop scalable parallel implementations of these methods. If realized this will revolutionize computation, enabling first principles calculations on truly nanoscale systems, such as enzymes and molecular electronic devices.Read moreRead less
Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved.

The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including optical masks, near-field optics, detector arrays, multi-photon imaging and digital deconvolution. Selected methods will be demonstrated with practical examples in multi-photon microscopy. Applications in super-high density optical recording will also be studied.Read moreRead less

Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develo ....Towards a high density silicon phase change memory device.

Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develop an entirely new information storage system: a high-density silicon phase change memory. This project aims to study small-scale transformation behaviour in silicon and to design demonstrator memory devices based on both micro-electromechanical systems and solid state technologies.Read moreRead less

This project aims to improve the performance of programming languages used by millions of Australians every day, such as Java, JavaScript and PHP by developing improved memory-management algorithms. These languages use what is referred to as “garbage collection” to ensure memory is managed without data loss, but do so conservatively and consequently cause performance challenges and energy overheads. This project expects to provide these languages with improved memory-management algorithms, and provides researchers and industry with a framework for innovation. This project will enable safe software that is more efficient on today's hardware and able to exploit emerging hardware. This project should lead to better performance and energy savings for server applications, phones, watches, and smart appliances, while ensuring memory safety.Read moreRead less

Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe ....Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe how these connections are recruited during learning and memory, and then to test their function experimentally. The outcomes will extend the known neural circuitry that controls learning by defining how and where these unexplored pathways fit within it; thus advancing knowledge regarding neural regulation of behaviour.

Exploring the nature of lexical representation. In order to comprehend and produce the words that we know, whether in speech or in writing, we must possess mental representations of each of those words (i.e., "lexical" representations). The aim of the proposed research is to elaborate on the nature of these representations in an attempt to understand more fully the cognitive mechanisms involved in proficient language use. The central idea to be explored is that underlying all lexical functioning ....Exploring the nature of lexical representation. In order to comprehend and produce the words that we know, whether in speech or in writing, we must possess mental representations of each of those words (i.e., "lexical" representations). The aim of the proposed research is to elaborate on the nature of these representations in an attempt to understand more fully the cognitive mechanisms involved in proficient language use. The central idea to be explored is that underlying all lexical functioning is an abstract phonological representation that is influenced by orthography. Furthermore, the possibility will be examined that poorer readers possess less abstract representations than do better readers.Read moreRead less
