Faculty of Engineering and Information Sciences - Papers: Part B

The identification of protein-protein interaction (PPI) is one of the most important tasks to understand the biological functions and disease mechanisms. Although numerous databases of biological interactions have been published in debt to advanced high-throughput technology, the study of inter-species protein-protein interactions, especially between human and bacterium pathogens, remains an active yet challenging topic to harness computational models tackling the complex analysis and prediction tasks. In this paper, we comprehensively revisit the prediction task of human-bacterium protein-protein interactions (HB-PPI), which is a first ever endeavour to report an empirical evaluation in learning and predicting HB-PPI based on machine learning models. …

Leveraging Smote In A Two-Layer Model For Prediction Of Protein-Protein Interactions, Huaming Chen, Lei Wang, Chi-Hung Chi, Jun Shen

Faculty of Engineering and Information Sciences - Papers: Part B

The research of the mechanisms of infectious diseases between host and pathogens remains a hot topic. It takes stock of the interactions data between host and pathogens, including proteins and genomes, to facilitate the discoveries and prediction of underlying mechanisms. However, the incomplete protein-protein interactions data impediment the advances in this exploration and solicit the wet-lab experiments to examine and verify the latent interactions. Although there have been numerous studies trying to leverage the computational models, especially machine learning models, the performances of these models were not good enough to produce high-fidelity candidates of interactions data due to the nature …

A Theoretical Model For Total Suction Effects By Tree Roots, Udeshini Pathirage, Buddhima Indraratna, Muditha Pallewattha, Ana Heitor

Faculty of Engineering and Information Sciences - Papers: Part B

Strengthening soft and weak soil by way of root reinforcement is a well-known strategy that is adopted worldwide. In Australia, native gum trees remain evergreen throughout the year and have been utilised to stabilise transportation corridors by way of reinforcement provided by the roots and the suction generated within the root domain as a function of evapotranspiration through the canopy. A mature gum tree can induce a missive total suction pressure exceeding 30MPa through its root water and solute uptake in terms of matric plus osmotic suction. This cumulative effect of matric and osmotic suctions contributes to the overall shear …

Healing At Home: Developing A Model For Ambulatory Alcohol "Detox" In An Aboriginal Community Controlled Health Service, Jonathan Brett, Angela Dawson, Rowena G. Ivers, Leanne Lawrence, Sarah Barclay, Kate M. Conigrave

Faculty of Science, Medicine and Health - Papers: part A

Indigenous Peoples who have been colonized typically face a greater burden of injury, disease, and social disruption associated with alcohol use (Kirmayer, Brass, & Tait, 2000). However, they often also encounter many barriers to accessing treatment for alcohol use disorders (Gray, Stearne, Wilson, & Doyle, 2010). Aboriginal and Torres Strait Islander Australians (here described as Aboriginal Australians) experience 3-8 times the prevalence of alcohol-related illness, injury, and death than the general population (Calabria, Doran, Vos, Shakeshaft, & Hall, 2010). But their barriers to treatment access for alcohol dependence include transport difficulties, fear of discrimination, and lack of culturally secure services …

Faculty of Engineering and Information Sciences - Papers: Part B

Statistical shape modelling is an efficient and robust method for medical image segmentation in computer-aided diagnosis. The key step in building a statistical shape model is to find corresponding landmarks in each instance of a training set. In this paper, a novel landmark correspondence estimation method that uses edge collapse surface simplification and the sphere registration is proposed. All the landmarks are selected and transformed by spherical conformal mapping from the instances of the training set and the associated correspondence are automatically found on the spheres.

An Integrated Model Of Staff Education And Service Support To Strengthen The Efficacy Of Technology-Based Crisis Services, Taneile Kitchingman, Peter Caputi, Ian G. Wilson, Alan Woodward

Faculty of Social Sciences - Papers (Archive)

Paper presented at the National Suicide Prevention Conference, 24-27 July 2016, Canberra, Australia.

Within Australia, non-clinical telephone and online crisis support services provide readily accessible support without the requirement of referral. Research shows that up to one third of callers to crisis lines and half of all visitors to crisis chat services may be suicidal at the time of contact. Research also shows that contact with these services reduces caller suicidality and facilitates engagement with necessary intervention. The number of contacts to crisis support services in Australia is increasing. An increase in contacts to technology-based crisis services highlights the need …
