Generalized covering designs and clique coverings

, 2011
Inspired by the "generalized t-designs" defined by Cameron [P. J. Cameron, A generalisation of t-designs, Discrete Math. 309 (2009), 4835--4842], we define a new class of combinatorial designs which simultaneously provide a generalization of both ...

Characterization of Microplastics in Human Gastric Cancer and Control Tissues and Analysis of Associated Genetic Features

Advanced Healthcare Materials, EarlyView.
This study characterizes the presence of microplastics in human normal gastric, para‐tumor, and gastric tumor tissue and confirms the association between microplastic exposure and lymph node metastasis in gastric cancer. This study explores the transcriptomic changes induced by microplastic exposure, laying the foundation for further investigation into

Colloid‐Mediated Synthesis of Hierarchically Porous Amorphous Catalyst for Durable Industrial‐Scale Water Electrolysis

Advanced Materials, EarlyView.
A colloid‐mediated electroless plating (CMEP) strategy is proposed to fabricate hierarchically porous, amorphous Fe‐doped NiWB electrocatalysts under ambient conditions. The in situ formation of Fe‐W‐O colloidal species guides the formation of robust, porous catalyst layers with excellent mass transfer and durability, sustaining 500 mA cm−2 for 2000 h,
