Characterization of Dolomite Reservoir Pore‐Throat Structure Based on Cast Thin Section Image Analysis and Fractal Theory: A Case Study of Middle Jurassic Dolomite in the Southern Depression of Qiangtang Basin, Northern Tibetan Plateau, China

Energy Science &Engineering, EarlyView.
The pore throat structure of the dolomite reservoir of the Buqu Formation in the Middle Jurassic in the Qiangtang Basin was evaluated by using the cast thin section image method combined with fractal theory. The results were combined with the reservoir space formation process to discuss the possible controlling factors of pore formation.

Signal design and analysis for cell identification in Sub-THz OFDM systems

ICT Express
Here we propose a new signal set design for physical cell identification (PCI) in sub-THz OFDM systems. We also derive useful properties of proposed signal set, which can be employed to assign PCI and reduce interference.

Integrative cross‐tissue analysis unveils complement‐immunoglobulin augmentation and dysbiosis‐related fatty acid metabolic remodeling during mammalian aging

iMeta, EarlyView.
Our study provides a comprehensive multi‐omics profile of aging, integrating proteomic, metabolomic, and metagenomic analyses across diverse tissues and plasma. We identified the synergistic amplification of the circulating complement system and tissue‐wide immunoglobulin accumulation as key molecular drivers of inflammaging.
