Title: Early Detection in Cognitive Aging: Neuropsychology as the Foundation for AI-Enabled Precision Brain Health.
Abstract
As the global population ages, dementia has emerged as a critical medical challenge, making the early detection of dementia or the identification of high-risk individuals before symptoms appear a key concern in both clinical practice and research. Additionally, effectively enhancing cognitive function in older adults is vital for improving quality of life. In this context, precision health, a rapidly advancing field, offers promising solutions. In this talk, I will present insights from our research team’s work on applying neuropsychological approaches to early detection and intervention in dementia within the framework of precision health. The discussion will focus on three key areas: examining the influence of various dementia risk factors on disease progression and their implications for early clinical detection; implementing behavioral interventions to enhance cognitive functions in older adults; and leveraging technology to facilitate cognitive assessment and interventions.
Short bio:
Yu-Ling Chang, Ph.D., is a Distinguished Professor in the Department of Psychology and the Graduate Institute of Brain and Mind Sciences at National Taiwan University (NTU). She is also affiliated with the Department of Neurology at NTU Hospital and serves as Director of the Imaging Center for Integrated Body, Mind, and Culture Research. Her research integrates neuropsychological assessment, multimodal brain imaging, and AI/advanced analytics to characterize heterogeneity in cognitive aging and to advance early detection and precision approaches to dementia risk. She has received several prestigious honors, including the National Science and Technology Council (Taiwan) Outstanding Research Award and the Ta-You Wu Memorial Award. She also serves in editorial leadership roles, including as an Associate Editor for Biological Psychology, the Journal of Alzheimer’s Disease, and Archives of Clinical Neuropsychology.
Title: On Some Ultra-Sharp Bounds in Queueing Systems
Abstract:
The talk introduces two new classes of ultra-sharp bounds in queueing systems. The first is specific to the G/G/1 queue, with possibly correlated inter-arrivals; the main result is an exact expression for the distribution of the delay in terms of a series, whose terms are subject to elementary integration. Remarkably, the first few terms are sufficient to render ultra-sharp bounds improving upon state-of-the-art bounds by orders of magnitude. The second new class of bounds is specific to a tandem queueing network with general (i.e., not necessarily Poisson) arrivals and light-tailed service times. Besides showing for the first time that the end-to-end delay distribution is subject to a polynomial-exponential structure, explicit bounds computed in some special cases are shown to improve upon state-of-the-art results by many orders of magnitude.
