MHRC studies lateral frontopolar cortex of human brains to understand human decision-making

Dr Bolton CHAU, Associate Director of the Mental Health Research Centre (MHRC) and Associate Professor in the Department of Rehabilitation Sciences, and his team discovered the function of a lateral frontopolar cortex (FPl), a brain region unique to humans, hence providing important insights as to why humans are capable of generating complex behaviours. The findings have been published in Cell Reports. With the use of brain imaging and artificial intelligence, the team identified that the FPl is involved in digesting complex information during decision-making. The FPI uses a parallel processing mechanism that decomposes high-dimensional choice information into simpler forms and transfers this simplified information to another region, the posterior cingulate cortex, to guide decision-making. The team also received a funding from the Collaborative Research Fund of the Research Grants Council (RGC) to conduct follow-up studies for three years. These studies aim to investigate the specific information represented in the FPl, develop artificial neural networks to reverse-engineer the FPl, and develop effective brain stimulation approaches to modulate the FPl. The studies will be conducted by a team comprising researchers from PolyU, The Chinese University of Hong Kong, Hong Kong Baptist University and the University of Oxford, and will leverage MHRC collaboration platform and the cutting-edge facilities of the University Research Facility in Behavioral and Systems Neuroscience (UBSN).   Read the full paper: https://www.cell.com/cell-reports/fulltext/S2211-1247(23)00566-1

RiFood-developed fungus-based fat replacer enables healthy low-fat indulgences

AkkMore™, a novel formula of fat replacer developed by the Research Institute for Future Food (RiFood), has been used in the production of low-fat food products including low-fat ice cream of 3% fat content. The innovation was developed by the team led by Dr Gail CHANG Jinhui, RiFood Core Member, and was awarded silver medal at the 2022 Special Edition of the Geneva International Exhibition of Inventions. AkkMore™ is produced from natural fungal sources, and has been tested for its effectiveness in bringing a number of health benefits, including preventing obesity and other metabolic diseases, enhancing gut health, modulating the immune response, and reducing anxiety. The research team is now working on “Cream Mate”, an AkkMore™-based cream substitute. Cream Mate enables cream products to contain less fat, to be able to be frozen for long time, and to extend shelf-life while holding sensory appeal comparable to traditional cream. The use of Cream Mate helps reduce calorie and the consumption of dairy products in the desserts, as well as the amount of food waste due to expiration. This helps food producers to make their production more sustainable and economical. In addition, RiFood is collaborating with Hotel ICON on the use of Cream Mate in preparing reduced-fat desserts to be served on the hotel regular menus, which will be available starting in early-June.

Prof. Ioannis BRILAKIS of University of Cambridge to deliver PAIR Distinguished Lecture on built environment digital twinning

PAIR cordially invites you to join our Distinguished Lecture on 8 March 2024 (Friday) at 3:00 p.m.–4:30 p.m. (Hong Kong Time) on the PolyU campus and via Zoom. The lecture titled “Digital Twinning the Built Environment” will be delivered by Prof. Ioannis BRILAKIS, Laing O’Rourke Professor of Civil & Information Engineering and Director of the Construction Information Technology Laboratory, University of Cambridge.    Digital Twinning methods can produce a reliable digital record of the built environment and enable owners to reliably protect, monitor and maintain the condition of their assets. The built environment is comprised of large assets that need significant resource investments to design, construct, maintain and operate them. Improving productivity, i.e., efficiency and effectiveness, and creating new, disruptive ways to address existing problems throughout their lifecycle can generate significant performance improvements in cost, time, quality, safety, sustainability, and resilience metrics for all involved parties. Creating and maintaining an up-to-date electronic record of built environment assets in the form of rich Digital Twins can help generate such improvements.   This talk introduces research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting Digital Twin, automatically extracting defect spatial measurements, and sensor and sensor data modelling. The results of these methods are further exploited through their application in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage.   Prof. Brilakis completed his PhD in Civil Engineering at the University of Illinois, Urbana Champaign in 2005. He then worked as an Assistant Professor at the Departments of Civil and Environmental Engineering, University of Michigan, Ann Arbor (2005-2008) and Georgia Institute of Technology, Atlanta (2008-2012) before moving to Cambridge in 2012 as a Laing O’Rourke Lecturer. He was promoted to Reader in October 2017 and to Professor in 2021. He has also held visiting posts at the Department of Computer Science, Stanford University as a Visiting Associate Professor of Computer Vision (2014) and at the Technical University of Munich as a Visiting Professor, Leverhulme International Fellow (2018-2019), and Hans Fischer Senior Fellow (2019-2023). He is a recipient of the 2022 EC3 Scherer Award, 2022 EC3 Thorpe Medal, 2019 ASCE J. James R. Croes Medal, the 2018 ASCE John O. Bickel Award, the 2013 ASCE Collingwood Prize, the 2012 Georgia Tech Outreach Award, a 2010 NSF CAREER award, and a 2009 ASCE Associate Editor Award.
