Acute and long-term changes in blood flow after ischemic stroke:challenges and opportunities

引用

Neural Regeneration Research 2023年第4期18卷 799-800页

作者： Dino Premilovac Brad A.Sutherland tasmanian School of Medicine College of Health and MedicineUniversity of TasmaniaHobartTASAustralia

The brain has a high metabolic rate and consumes approximately 20% of the total energy in the body at any given time. Although it requires a large amount of energy to function, the brain cannot store significant amounts of energy making it exquisitely dependent on constant nutrient supply via blood flow. When blood flow to the brain is impaired, such as during stroke, there are rapid and severe consequences for the neurons that depend on this constant energy supply.

Strigolactones redefine plant hormones

引用

Science China(Life Sciences) 2016年第10期59卷 1083-1085页

作者： Lu Wang Steven M.Smith School of Biological Sciences University of Tasmania Institute of Genetics and Developmental Biology Chinese Academy of sciences

A commonly accepted view of plant growth hormones is that their interaction with the cognate receptor protein is reversible, so that each hormone molecule can potentially interact multiple times with a receptor and so either amplify the hormone signal or maintain it over an extended period of time. The signal can be ＇cancelled＇ by degrading the hormone. Strigolactones present us with a potentially new paradigm. The receptor is a serine hydrolase-type protein which attacks the strigolactone resulting in covalent modi- fication of the receptor, while at the same time destroying the hormone. Strigolactone is apparently a one-use ＇dispos- able＇ hormone.

Preliminary evidence indicating Dome A (Antarctica) satisfying preconditions for drilling the oldest ice core

引用

Chinese Science Bulletin 2008年第1期53卷 102-106页

作者： XIAO CunDe LI YuanSheng HOU ShuGui lan ALLISON BIAN LinGen REN JiaWen State Key Laboratory of Cryospheric Sciences Cold and Arid Regions Environmental and Engineering Research institute Chinese Academy of Sciences Lanzhou 730000 China Chinese Academy of Meteorological Sciences Beijing 100081 China Polar Research Institute of China Shanghai 200129 China Australian Antarctic Division and Antarctic Climate and Ecosystems CRC Tasmania 7001 Australia

Lowest temperature and snow accumulation rate are preconditions for retrieving the oldest ice core from the polar ice sheets. The 10-m depth firn temperature at Dome A, the summit of the Antarctic Ice Sheet, recorded by an automatic weather station (AWS) was -58.3℃ in 2005 and -58.2℃ in 2006, re-spectively. The 10-m firn temperature is an approximation of the annual mean air temperature (AMAT), and this is the lowest AMAT that has been recorded on the surface of the Earth. The stable isotopic ratios (δ 18O and δ D) of surface snow at Dome A are also lower than at other ice sheet domes along the East Antarctic Ice Divide such as Dome C, Dome F, Dome B and Vostok. These facts indicate that Dome A is the "pole of cold" on the Earth. The total amount of snow accumulation rate in 2005 and 2006 was only 0.16 cm, equaling 0.016 m water equivalent per year, the lowest precipitation ever recorded from Antarctica. Preliminary evidences indicate that Dome A is a candidate site for recovering the oldest ice core.

Constrained coordinated distributed control of smart grid with asynchronous information exchange

作者： Benjamin MILLAR Danchi JIANG Md.Enamul HAQUE School of Engineering&ICT University of TasmaniaHobartAustralia School of Engineering Deakin UniversityMelbourneAustralia

Smart grid constrained optimal control is a complex issue due to the constant growth of grid complexity and the large volume of data available as input to smart device *** this context,traditional centralized control paradigms may suffer in terms of the timeliness of optimization results due to the volume of data to be processed and the delayed asynchronous nature of the data *** address these limits of centralized control,this paper presents a coordinated,distributed algorithm based on distributed,local controllers and a central coordinator for exchanging summarized global state *** proposed model for exchanging global state information is resistant to fluctuations caused by the inherent interdependence between local controllers,and is robust to delays in information *** addition,the algorithm features iterative refinement of local state estimations that is able to improve local controller ability to operate within network *** of the proposed coordinated,distributed algorithm through simulation shows its effectiveness in optimizing a global goal within a complex distribution system operating under constraints,while ensuring network operation stability under varying levels of information exchange delay,and with a range of network sizes.

Journal of Donghua University(English Edition) 2006年第6期23卷 15-19页

作者：袁红春陈莹孙越夫 College of Information Technology Shanghai Fisheries University School of Information Systems University of Tasmania

The massive web-based information resources have led to an increasing demand for effective automatic retrieval of target information for web applications. This paper introduces a web-based data extraction tool that deploys various algorithms to locate, extract and filter tabular data from HTML pages and to transform them into new web-based representations. The tool has been applied in an aquaculture web application platform for extracting and generating aquatic product market information. Results prove that this tool is very effective in extracting the required data from web pages.
