Industry Portfolio Volatility Connections and Industry Portfolio Returns

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper tracks dynamic connections that form among daily US industry portfolio return volatilities using a Bayesian time‐varying parameter VAR model. Market participants often focus on sectors to filter vast amounts of information, and this focus results in cross‐industry return predictability. We characterise connections that form over the

Artificial intelligence–driven decoupling structure–activity relationship for lithium‐ion batteries

InfoScience, EarlyView.
Artificial intelligence can efferently accelerate the high‐throughput screening of battery materials, the analysis of multiphase mechanisms, and the precise prediction of capacity and cycle life. This review systematically summarizes the applications of machine learning (ML) in decoupling the complex structure‐activity relationships of lithium‐ion ...

Facet‐engineered BiSI nanorods for intelligent distinguishing detection of NO2/H2S mixed gas

InfoMat, EarlyView.
Mixed toxic gases such as NO2 and H2S can threaten safety in coal mines and industrial settings, but it is still difficult to monitor them accurately with a simple sensor. In this work, we improved a BiSI‐based room‐temperature gas sensor through crystal facet engineering and combined it with machine learning so that one sensor could distinguish mixed ...

Evaluating Water–Energy–Food Nexus Strategies to Address Resource Scarcity in the Crocodile River Catchment, South Africa

Irrigation and Drainage, EarlyView.
ABSTRACT The water–energy–food (WEF) nexus approach highlights the interdependence of water, energy and food resources, all of which play central roles in agriculture, especially irrigation. A WEF nexus lens was applied to Mpumalanga's Crocodile River catchment, a vital irrigation area that significantly contributes to South Africa's staple food ...

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.
