Insult to Injury: Population Impacts of Sublethal Entanglement and Vessel Strikes of Common Bottlenose Dolphins (Tursiops truncatus) in Barataria Basin, Louisiana, 2011–2023

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Human interactions, specifically fishery entanglements (FI) and vessel strikes (VI), threaten marine mammals, including the Barataria Bay Estuarine System (BBE) Stock of common bottlenose dolphins (Tursiops truncatus). We reviewed whole‐body photographs to estimate the prevalence of sublethal entanglement and vessel strike scars for 227 ...

Reengaging Criminology in Regulation and Governance: A Synergistic Research Agenda on Regulatory Guardianship

Regulation &Governance, Volume 20, Issue 4, Page 1281-1294, October 2026.
ABSTRACT Recent literature calls for scholars to bridge the divide that has emerged between criminology and regulation and governance. In the current work, we propose that criminological opportunity theories provide one fruitful pathway to that end.

Flow Characteristics and Response Surface Methodology‐Based Pressure‐Loss Prediction Models for the Reverse Circulation Converter in Double‐Wall Drill Pipes

Energy Science &Engineering, Volume 14, Issue 9, Page 4282-4299, September 2026.
Flow characteristics and pressure loss mechanisms of a reverse circulation converter in dual‐wall drill pipes are systematically investigated using CFD and response surface methodology. The results reveal the dominant role of inertial dissipation and provide a predictive framework for optimizing converter design and operational parameters. ABSTRACT The

Boron Isotope Evidence for Reduced Ventilation of the Deep Arctic Ocean During the Last Glacial Period

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Understanding the ventilation of the deep ocean, where most ocean carbon is stored, is essential to understanding how changes to ocean carbon budgets contribute to climate change. In the Arctic Ocean, shifts in ice cover, stratification and temperature are likely to impact carbon sequestration in the ocean interior.

Gas kick and lost circulation risk identification method with multi-parameters based on support vector machine for drilling in deep or ultradeep waters

Engineering Science and Technology, an International Journal
In deepwater and ultra-deepwater drilling, formation pressures are complex and the drilling fluid density window is narrow, which makes it prone to well control incidents such as kicks and lost circulation.
