Study on mechanical properties of steel-wood composite bolt tray under ultimate load

Meikuang Anquan
In order to reduce the damage of dynamic pressure impact to the support system and meet the needs of large deformation roadway, the bearing capacity model of anchor arch steel tray was constructed based on the spherical shell structure theory.

A Modular PLUG‐IN Photosynthetic Chassis With Tunable Thermal Control for Mammalian Systems

Advanced Science, EarlyView.
This work establishes a “plug‐in” chassis compatible with mammalian systems that synchronizes growth, production, and cell‐wall re‐configuration, providing a versatile platform for photosynthetic bioproduction and microalgal synthetic biology. ABSTRACT Microalgae are promising photosynthetic platforms for high‐value compounds, yet their industrial use ...

String Figuring young children's perspectives of quality in English early childhood education and care

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Coexistence, crossover and extirpation in coalescent communities and ecotones

Oikos, EarlyView.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Universal Phase Identification of Block Copolymers From Physics‐Informed Machine Learning

Journal of Polymer Science, Volume 63, Issue 6, Page 1433-1440, 15 March 2025.
ABSTRACT Block copolymers play a vital role in materials science due to their diverse self‐assembly behavior. Traditionally, exploring the block copolymer self‐assembly and associated structure–property relationships involve iterative synthesis, characterization, and theory, which is labor‐intensive both experimentally and computationally.
