Brain-to-Brain Coupling Is Associated With the Benefits of Delayed Imitation in Skill Acquisition: An fNIRS Study
1 Introduction Learning by observing and imitating others is a fundamental ability. This process, known as observational learning, allows individuals to acquire new behaviors or skills (Bandura 1977). Many studies in educational psychology have demonstrated the benefits of observational learning, which helps people master motor skills (Francisco et al. 2023), gain knowledge (Zhidan, Williamson, et al. 2015), understand rules (Zhidan, Meltzoff, et al. 2015), and form social attitudes (Skinner et al.
Longitudinal trajectories of internet use, attitudes toward aging, and depression: a latent growth mediation model
Abstract Objectives: Whether Internet use affects depression in older adults in china via aging attitudes remains unclear. Moreover, few longitudinal studies have been conducted. Methods: After excluding missing data, the final sample comprised 4,039 older adults (aged ≥60 years) from the 2018, 2020, and 2023 waves of the China Longitudinal Aging Social Survey (CLASS).
The impact of education on health transitions, life expectancy, and healthy life expectancy among older adults in China - Humanities and Social Sciences Communications
Abstract This paper aims to explore the impact of education on health transitions, Life Expectancy (LE), and Healthy Life Expectancy (HLE) among older adults in China. Data from the Chinese Longitudinal Healthy Longevity Survey were utilized. Multi-state Markov models with continuous time were employed to estimate how education impacts health transitions, HLE, LE and the ratio of HLE to LE (HLE/LE).
Lithography-free, site-controlled germanium quantum dots in silicon nanowires for single-hole transistors operating up to 50 K
Abstract Precise control over quantum dot (QD) position and size is critical for quantum electronics but typically requires complex nanofabrication. Here, we report a step-confined heteroprecursor supply (sc-HPS) strategy for growth of crystalline germanium (c-Ge) QDs at predefined step edges within planar ultrathin silicon nanowire (SiNW) channels, eliminating the need for high-resolution lithography.
Reinforcing the Stability of Cobalt-free Lithium-rich Layered Oxides via Li-poor Ni-rich Surface Transformation
Reinforcing the Stability of Cobalt-free Lithium-rich Layered Oxides via Li-poor Ni-rich Surface Transformation Lithium-rich layered oxides are one of the most promising cathode materials for lithium-ion batteries due to their super-high capacity and low cost. However, the extensive surface destructions, originated from the side reactions between the oxidative surface and the reductive electrolyte, lead to the fast capacity fading along with the inevitable voltage drop.

Room-temperature valleytronic transistor
Abstract Valleytronics, based on the valley degree of freedom rather than charge, is a promising candidate for next-generation information devices beyond complementary metal–oxide–semiconductor (CMOS) technology1,2,3,4.
Highly stretchable graphene nanoribbon springs by programmable nanowire lithography
Abstract Graphene nanoribbons are ideal candidates to serve as highly conductive, flexible, and transparent interconnections, or the active channels for nanoelectronics. However, patterning narrow graphene nanoribbons to <100 nm wide usually requires inefficient micro/nano fabrication processes, which are hard to implement for large area or flexible electronic and sensory applications.
Bottom-up synthetic hierarchical buffer structure of copper silicon nanowire hybrids as ultra-stable and high-rate lithium-ion battery anodes
Silicon (Si) is a promising anode material for next-generation high-energy lithium-ion batteries (LIBs). However, large volume changes and low intrinsic electrical conductivity of silicon materials result in poor cycle performances, especially at a high Si loading. To tackle the two critical problems, we here report an Al2O3 coated hierarchical copper-silicon nanowire structure (HCS NW) using a crossing-interconnected-hierarchical-hollow (CIHH) bottom-up strategy.
