Evolutionary Mechanisms Of Nanopores And Adsorption Capacity In Shales Under Scco2-Water-Rock Interactions, Feng Guangjun, Wang Meng, Zhu Yanming, Song Yu, Dai Xuguang, Zheng Sijian, Xie Hong, Shang Fuhua

Coal Geology & Exploration

Background Supercritical carbon dioxide (ScCO₂ )-enhanced shale oil and gas recovery serves as an effective approach to geologic CO₂ sequestration. Injecting ScCO₂ into shale reservoirs can trigger complex ScCO₂-water-rock interactions, thereby altering the material composition, nanopore structure, and adsorption capacity of shales. Examining their evolutionary processes represents a critical scientific issue in the evaluation of CO₂ sequestration efficiency. Methods This study investigated the shales of the Longmaxi Formation in the southeastern Chongqing area. Through simulation experiments on ScCO₂-water-rock interactions and by integrating X-ray diffraction (XRD), low-pressure CO₂/N₂ adsorption, fractal …

Agentic Intelligence Under Constraint: Energy, Context, And The Expansion Of Exchange, Nick Loghmani

iSchool - All Scholarship

Recent advances in agentic artificial intelligence have been driven primarily by scale: larger models, increased data, and expanding computational resources. However, rising energy costs, inference latency, and hardware constraints increasingly challenge this trajectory. This paper argues that intelligence—biological or artificial—does not primarily scale through raw computational expansion, but through the management of exchange under constraint. Drawing on cognitive science, systems theory, and prior work on exchange-based models of intelligence, the paper proposes a theoretical framework in which agentic intelligence scales through context management, proceduralization, and the assembly of reusable units of exchange. Unlike approaches that focus solely on model compression …

Furthermore, the platform can offer a scientific basis for formulating related policies and conducting technological R&D.Methods This study proposed and developed a comprehensive evaluation system for …

Nutrition Assistance Programs And Pediatric Weight Outcomes: A Systematic Review, Dan Ferris, Genevieve Davison, Tyler Frank, Amanda Gilbert, Fanice Thomas, Sydney Rothman, Kim Lipsey, Sarah Moreland-Russell

2020-Current year OA Pubs

BACKGROUND/OBJECTIVES: Food insecurity and pediatric obesity have increased concurrently in the U.S., raising questions about the role of Federal Nutrition Assistance Programs (FNAPs) in shaping weight outcomes. This systematic review examined evidence on relationships between FNAP participation and pediatric weight outcomes.

METHODS: Six databases were searched for U.S.-based, peer-reviewed studies published through July 2024 that assessed FNAP participation and pediatric weight outcomes.

RESULTS: Seventy-five studies met the inclusion criteria, and no consistent pattern indicated that any single FNAP or program type (educational setting-based or direct financial support) reliably reduced or increased childhood overweight or obesity risk. Twenty studies found statistically …
