In Physics of Fluids, researchers in China focus on enhancing the aerodynamic performance of autonomous vehicles by reducing drag induced by externally mounted sensors such as cameras and light detection and ranging instruments. After establishing an automated computational platform, they combined the experimental design with a substitute model and an optimization algorithm to improve the structural shapes of AV sensors. They then performed simulations of both the baseline and optimized models. After optimizing the design, researchers found a 3.44% decrease in the total aerodynamic drag of an AV.

Researchers from HHMI's Janelia Research Campus and collaborators have developed a new AI method that produces sharp microscopy images throughout a thick biological sample without using adaptive optics, adding additional hardware, or taking more images.

So-called "phantom agents" are suspected pathogens that have been reported in scientific literature going back to the early 1900s with no real evidence they exist. Most of these phantom agents were described before modern molecular techniques, and there are no samples or genome sequences available to study them. Despite the lack of evidence of their existence, the suspected pathogens made their way into international regulations that control the shipment of plant materials. The result is a confusing mix of real and phantom agents on regulatory lists that must be ruled out by the sender before plants can be shipped from country to country. In a Plant Disease article recently published by the American Phytopathological Society, Ioannis Tzanetakis at the Arkansas Clean Plant Center and co-authors from more than 40 countries identify phantom agents in eight crops that still appear on regulated pathogen lists even though there is no way to accurately test for them.

Kyushu University researchers have successfully developed a new ferroelectric optical modulator that can exhibited modulation of up to 170 Gbps—an operating 10 times higher than existing devices—and a transmission rate of more than 300 Gbps. This modulator was made thanks to a new method the team developed that allowed them to grow thin films of ferroelectric crystals on silicon substrates.

On October 2nd (Wednesday), Korea University College of Medicine (Dean: Pyun Sung-Bom) hosted a forum titled “Advancing Healthcare through Innovations in Data and AI in Clinical Informatics and Natural Language Processing” in the 6th-floor lecture hall of the First Medical Building.
