Engaging the Underground: An STS Field in Formation
Engaging Science, Technology, and Society, 2018 Rather than existing a priori, the underground comes to be through interlinked political, economic, cultural, and technoscientific practices and processes.

Proceedings of the 2009 SIAM International Conference on Data Mining, 2009 We introduce the problem of grammar mining, where patterns are context-free grammars, as a generalization of a large number of common pattern mining tasks, such as tree, sequence and itemset mining. The proposed system offers data miners the possibility to specify and explore pattern domains declaratively, in a way which is very similar to the ...

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Energy Procedia, 2012 AbstractWith the mine development and utilization, the mine environment problems and subordinate geology disaster phenomenon it causes have been revealed gradually, some also lead to serious results. Therefore, the balanced relation of “resources mining - environmental protection - mining area sustainable development” is a very important topic of ...
