Surface Chemical Analysis of Plastic Materials by X‐Ray Photoelectron Spectroscopy: Understanding Weathering, Fragmentation and Contaminant Uptake in Marine Environments

Macromolecular Materials and Engineering, EarlyView.
This Perspective demonstrates how X‐ray photoelectron spectroscopy (XPS) uncovers surface chemical changes in plastics, providing insight into weathering‐driven fragmentation and contaminant adsorption. The Perspective underscores XPS's pivotal role in elucidating fragmentation mechanisms, predicting pollutant–plastic interactions, and guiding ...

Machine Learning for Predictive Modeling in Nanomedicine‐Based Cancer Drug Delivery

Med Research, EarlyView.
The integration of AI/ML into nanomedicine offers a transformative approach to therapeutic design and optimization. Unlike conventional empirical methods, AI/ML models (such as classification, regression, and neural networks) enable the analysis of complex clinical and formulation datasets to predict optimal nanoparticle characteristics and therapeutic

An Exact Method for Reliable Shortest Path Problems With Correlation

Networks, EarlyView.
ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for

Lions as Bone Accumulators? Exploring Multi‐Predator Contributions to the Olduvai Carnivore Site (OCS) (Tanzania) Through AI and Metric Analyses

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...
