Researchers use AI to develop dynamic modeling of brain graphs, capturing dynamics in continuous time for more accurate predictions and personalized treatment of brain diseases. The project aims to track disease development in individual patients and identify biomarkers associated with brain disorders.
GOBI overcomes model-free and model-based inference method limitations by introducing an easily testable condition for a general monotonic ODE model to reproduce time-series data. It successfully infers positive and negative regulations in various networks, distinguishing between direct and indirect causation.
Researchers develop a computational level set method to optimize sensor placement for maximum surveillance in complex environments. The model acknowledges finite range, limited viewing angle, and nonzero failure rate of realistic sensors, yielding accurate sensory constraints and optimal viewing directions.
Linda J.S. Allen, a renowned mathematician at Texas Tech University, has been recognized with the AWM-SIAM Sonia Kovalevsky Lecture award for her significant contributions to ordinary differential equations, difference equations, and stochastic models, particularly in the areas of infectious diseases and ecology.
Gerhard Wanner has been awarded the SIAM's George Pólya Prize for Mathematical Exposition, recognized for his effective communication of deep mathematics in books on numerical ODEs and geometric integration. He received the prize for his cumulative impact on teaching and understanding analysis and geometry.
Steven J. Ruuth, a professor at Simon Fraser University, has made significant contributions to the understanding of numerical solutions for ordinary and partial differential equations. The Germund Dahlquist Prize recognizes his original work on implicit-explicit methods and strong stability of numerical schemes.
Researchers have developed a new approach to solve systems of ordinary differential equations by separating time steps for slowly and rapidly varying components. This method leverages multirate techniques to improve computational efficiency.
