About the award-receiving projects:
Intracranial Large Artery Atherosclerotic Stroke: Epidemiology, Diagnosis, Pathogenesis, Imaging and Treatment
Stroke is the second leading cause of death in the world. The research team led by Prof. Wong Ka-sing Lawrence confirmed that intracranial large artery disease is the most common cause of stroke in the Chinese population, and for the first time found that artery-to-artery embolism was an important mechanism in stroke patients with large artery disease. Professor Wong’s team performed studies to explore pathogenesis of ischemic stroke, observed postmortem cerebral arteries and compared pathologic findings with clinical MRI results. They also introduced intracranial stenting therapy to Hong Kong with a much lower incidence of intraoperative complications than that of other stroke centres, reaching the world-class standard. Findings of Professor Wong’s original studies have produced over 200 papers in several well-known international medical journals, including a number of SCI papers, which have been cited for over 3,000 times totally.
Neurodynamic Optimization Model Design and Applications
The neurodynamic optimization research aims at building brain-like dynamic models for constructing intelligent systems, contributing to finding optimal solutions for ubiquitous optimization problems in science and engineering. Prof. Wang Jun has made significant contributions in neurodynamic optimization and its applications by developing a complete framework for theoretical analysis and model design which can be applied in scientific computing, data and signal processing, intelligent robots, intelligent control, network flow optimization, and associative memories etc. Over 100 papers about Professor Wang’s research were published in SCI journals and the total number of ISI citations reached over 4,500, well-recognized by many distinguished scholars. Professor Wang was elected IEEE Fellow in 2006, received a 2008-2009 Research Excellence Award from CUHK, a 2009 Natural Science Award (first class) from Shanghai Municipal Government, and the 2011 Outstanding Achievement Award from Asia Pacific Neural Network Assembly.
Iterative Solvers for Toeplitz Systems and their Applications
Toeplitz systems are matrix equations involving Toeplitz matrices. Such systems arise in applications like noise recognition in signal processing, deblurring of pictures in image processing, solution of elliptic partial differential equations, solution of electromagnetic field in integral equations, pricing of financial options in integro-differential equations, and evaluating network loadings in queuing systems. Prof. Chan Hon-fu Raymond has developed superfast iterative solvers for different kinds of Toeplitz systems arising from various applications, overcoming the instability problem and high computational cost in direct solvers, especially for problems in high-dimensional spaces. His techniques and methods have laid down the theoretical foundation and framework for the study of iterative Toeplitz solvers. Prof. Raymond Chan’s research work is highly regarded by his peers and his papers have been cited over 2,000 times (ISI). He has been listed in the ISI Science Citation List of Top 250-Highly Cited Mathematicians in the world since 2004 and, in that particular year, only two mathematicians from mainland China, Hong Kong and Taiwan were on the list. Professor Chan was also the recipient of the Leslie Fox Prize, the Feng Keng Prize of Scientific Computing, and the Morningside Medal of Mathematics.
Novel Echocardiographic Applications for Heart Failure – From Prevention to Treatment
Heart failure has become an important public health issue especially in an ageing society with increasing prevalence of cardiac diseases. Prof. Yu Cheuk-man’s research team demonstrated the superiority of biventricular pacing over conventional right ventricular apical pacing in the prevention of the deterioration of left ventricular systolic function through the first international multicenter clinical trial (PACE) with real-time three-dimensional echocardiography. They established the ‘Yu Index’ that comprehensively elucidated the important role of systolic dyssynchrony in the prevalence, occurrence, progression and prognosis of heart failure. The team also developed a predicting prognosis for patients with heart failure and identified parameters derived from tissue Doppler imaging as new prognosticators. A total of 95 papers have been published in leading peer reviewed journals and cited for over 5,000 times. The results were introduced in various international conferences and a number of innovative findings have been implemented as standard methods in the field.
Study and Application of Magnetic Resonance Molecular Imaging and Functional Imaging
Molecular imaging and functional imaging overcome the limitations of traditional imaging techniques and provide more accurate disease diagnosis and therapeutic response evaluation. The research team led by Prof. Wang Yixiang and Prof. Leung Cham-fai Ken synthesized a number of molecular imaging probes through utilization of new materials and methods. Successful outcomes were achieved in the areas of oncology, cell tracking, cardiovascular and cerebral diseases. The team also combined functional MR imaging with various data processing techniques to systematically study Alzheimer’s disease, depression, Autism Spectrum Disorders (ASD) and their pathogenesis, neuro-imaging and biomarkers to propose methods for early diagnosis and intervention.
Innovations and Technological Advancement in Preventing Peptic Ulcer Bleeding
After a decade of clinical research, the Instituteof Digestive Diseaseat CUHK has revolutionized the management of bleeding peptic ulcers and changed clinical practice worldwide. Innovative treatment solutions include: the use of profound acid suppression with high dose proton pump inhibitors after endoscopic therapy; novel endoscopic treatment for hemostasis of bleeding ulcers as well as trans-arterial embolization to prevent peptic ulcer re-bleeding among high risk patients; and new strategies for preventing re-bleeding among NSAID and aspirin users. These groundbreaking solutions have become new international standards of treatment for bleeding peptic ulcers and the research results were published widely in a number of high impact journals, including New England Journal of Medicine and Lancet, and cited over 1,700 times.

The Higher Education Outstanding Scientific Research Output Awards (Science and Technology) is set up by the MoE to recognize outstanding research projects at all tertiary institutions in mainland China. Since 2009, Hong Kong’s tertiary institutions have been included in the scheme. The award is presented to individuals or units who have made remarkable contributions in the areas of scientific discovery, technological innovation, science and technology advancement and implementation of patented technologies. The Natural Sciences Award honours researchers who have made discoveries in natural science and applied science, or given explanations to natural phenomena and characteristics; the Scientific and Technological Progress Award honours research achievements in applied technologies of natural science.
