AI now assists pathologists in detecting cancerous cells and making accurate diagnoses.   AI diagnosis models achieve accuracy rates of 96.0% and 95.3% when used to classify histopathological images of gastric and colorectal endoscopic biopsy specimens, respectively, into three classes. They are currently in service, assisting pathologists in the field, as the core components of a post-analytic daily quality-...

Cancer survival correlates with lymphocyte counts in chemoradiotherapy   Investigations into lymphocyte dynamics, i.e., depletion and recovery, during radiotherapy have revealed a strong correlation with the survival of patients undergoing concurrent chemoradiotherapy and adjuvant immunotherapy. Voxel-based analysis further indicates a high correlation between the radiation dose to large vessels and lymphopen...

Highly reliable dynamic memristor for artificial neurons and neuromorphic computing   Professor Shinhyun Choi’s group has developed a dynamic memristor crossbar array with high reliability, enabling a memristor-based neuromorphic computing system for energy-efficient artificial intelligence.   Article | Fall 2022     A memristor is an emerging memory device that stores information us...

Now you can see floral scents!   Optical interferometry visualizes how often a lily emits volatile organic compounds (VOCs) (here, referred to as floral scents). We find that lily flowers emit volatile compounds discontinuously, with pulses observed approximately every 10 to 50 min.   Article | Fall 2022     In nature, plants have been evolving for hundreds of millions of years. It has bee...

Sensing accident-prone features in urban scenes for proactive driving and accident prevention   This work proposes an attentive driving system based on visual notifications for proactive accident prevention. Context-specific accident-prone features are identified and drivers are notified of the detected accident-prone features in a proposed head-up display to enhance their decision-making.   Article ...

Can AI empower college students to be their own health agent?   Many college students report that they experience varying levels of stress throughout their college experience. Researchers study how an algorithmic stress prediction system can promote mental health for college students suffering from stress and depression.   Article | Fall 2022     One in four Koreans suffers from mental hea...
