An Osaka Metropolitan University researcher investigated factors influencing older adults’ acceptance and use of demand-responsive transport (DRT) in Senboku New Town, Osaka. The study found a significant relationship between citizen engagement and behavioral intention to use DRT.

The question of whether piano timbre can be changed according to a pianist’s intent had not been answered in over 100 years.

Using proprietary non-contact sensors capable of measuring key positions at 1000 fps, we measured key movements when professional pianists played using various timbres.

Data science and psychophysical experiments revealed that timbres intended by pianists were perceived by listeners, regardless of whether they had any piano playing experience.

Sounds produced by keystrokes differing only in specific key movement features were perceived as distinct timbres, thereby identifying a causal relationship between key movement and timbre.

The University of Osaka researchers developed a reinforcement learning framework that lets dialogue systems efficiently learn new words while asking fewer questions. This approach enhances user experience and enables future systems to naturally acquire family-specific nicknames and expressions, becoming more familiar companions in everyday life.

Scientists have unveiled a pioneering method that could help farmers reclaim lands blighted by toxic metals and boost the safety of crops grown in contaminated soils. The study, led by a research team in China, reveals that phosphorus-modified biochar, a carbon-rich material derived from apple tree branches, can dramatically reduce the threat posed by heavy metals in agricultural soils near mining areas.

Research has opened the door for coastal wetland restoration projects to potentially earn tradeable biodiversity certificates.
