The team proposed a prenatal depression detection method using the semantically enhanced option embedding (SEOE) model to represent questionnaire options. It can quantitatively determine the relationship and patterns between options and depression.

In nature, phenomena involving multiple fluctuations often arise interactively. At the ASDEX Upgrade^*1 experimental device in Germany, two plasma fluctuations driven by energetic particles have been observed in conjunction. Assistant Professor Hao Wang and Professor Yasushi Todo of the National Institute for Fusion Science (NIFS), in collaboration with researchers from the Max Planck Institute for Plasma Physics in Germany, successfully reproduced the coupled generation of the two fluctuations using a simulation code developed at NIFS and performed on a supercomputer. Through detailed analysis, they clarified that as the first fluctuation grew, the distribution function^*2 of the energetic particles was significantly deformed, which caused the second fluctuation to occur in conjunction. Energetic particles and fluctuations are deeply involved in maintaining the high-temperature plasma necessary for the realization of fusion energy. This achievement will greatly contribute to research in these areas.

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion. The DNA-nanoparticle motor uses the "burnt-bridge" Brownian ratchet mechanism. In this type of movement, the motor is being propelled by the degradation (or "burning") of the bonds (or "bridges") it crosses along the substrate, essentially biasing its motion forward.

These nano-sized motors are highly programmable and can be designed for use in molecular computation, diagnostics, and transport. Despite their genius, DNA-nanoparticle motors don't have the speed of their biological counterparts, the motor protein, which is where the issue lies. This is where researchers come in to analyze, optimize, and rebuild a faster artificial motor using single-particle tracking experiment and geometry-based kinetic simulation.

Two of UVA Engineering’s image analysis stars have been tapped by IEEE’s Signal Processing Society to share their expertise and insights with their society colleagues.

Experiments from the Caltech lab of Chiara Daraio, G. Bradford Jones Professor of Mechanical Engineering and Applied Physics and Heritage Medical Research Institute Investigator, have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM (for polycatenated architected materials) could have uses in areas ranging from helmets and other protective gear to biomedical devices and robotics.
