Researchers identify a homozygous SPAG9 gene mutation associated with intellectual disability, progressive cognitive decline, and heterogeneous brain abnormalities. The study provides a unique model for understanding disruptions in cellular transport mechanisms leading to neurodevelopmental and degenerative brain conditions.
A new vehicle allocation strategy for dockless bike-sharing systems at night can improve the balance of urban transportation and reduce traffic congestion. The approach uses a three-way classification method and behavioral decision theory to forecast demand and optimize resource allocation, reducing waste and enhancing system efficiency.
A new model based on the Langevin equation offers insights into exotic nuclei formation, enhancing the production of rare isotopes for scientific and medical applications. The model simplifies complex nuclear reactions by focusing on key physical processes, reducing adjustable parameters and improving energy dissipation predictions.
A novel variant of tissue-like P systems with polarizations is proposed to solve the SAT problem in polynomial time, achieving theoretical feasibility for precise rule control in specific applications.
As stand age increases, Pinus massoniana consistently absorbs bioavailable phosphorus from the soil, reducing soil phosphorus availability. Phosphorus distribution affects various organs in four distinct forms, and resorption influences this process.
Ancient DNA analysis reveals the Viking Age trade routes of walrus ivory, confirming early encounters between European Norse and North American Indigenous peoples. Genetic fingerprinting identified specific Arctic hunting grounds as the source of traded ivory.
