Externalizing as a common genetic influence for a broad spectrum of substance use and behavioral conditions: A developmental perspective from the Avon Longitudinal Study of Parents and Children

Addiction, Volume 120, Issue 12, Page 2559-2572, December 2025.
Abstract Background and aims Recent large studies have established the genetic basis of several conceptually linked phenotypes of externalizing. Polygenic risk scores (PRSs) for these constructs are associated with a range of substance use and mental disorder phenotypes but have not been examined with both pharmacological and non‐pharmacological ...

Numerical Representation of Contemporary Atmospheric Δ14CO2: 1. Time‐Varying Global Fluxes and Atmospheric Mass Balance

Global Biogeochemical Cycles, Volume 39, Issue 11, November 2025.
Abstract Precise measurements of 14C:C in atmospheric CO2 (expressed as Δ14C) are increasingly used in contemporary carbon cycle studies as a tracer of various processes, including anthropogenic CO2 emissions from combustion of fossil fuels and cement production.

Carbon costs of different pathways for reducing fire hazard in the Sierra Nevada

Ecological Applications, Volume 35, Issue 7, October 2025.
Abstract Restoring a low‐intensity, frequent‐fire regime in fire‐prone forests offers a promising natural climate solution. Management interventions that include prescribed fire and/or mechanical treatments have effectively reduced fire hazards in the Western United States, yet concerns remain regarding their impact on forest carbon storage. This study

Environmental Impacts of Diverting Crop Residues to Fuel Use [PDF]

, 1997
Shortage of fuel wood has lead many rural people to switch to using agricultural residues as an alternative energy source. However this has not always been met with universal acclaim due to the role of residues as fertilisers.

The ocean carbon sink – impacts, vulnerabilities and challenges [PDF]

, 2014
Carbon dioxide (CO2) is, next to water vapour, considered to be the most important natural greenhouse gas on Earth. Rapidly rising atmospheric CO2 concentrations caused by human actions such as fossil fuel burning, land-use change or cement production ...

Coral Data Reveal the Impact of the Great Acceleration on the Carbon Cycle in the Western Tropical South Atlantic

Paleoceanography and Paleoclimatology, Volume 40, Issue 7, July 2025.
Abstract The Great Acceleration is defined as a series of unprecedented, global human‐driven changes that occurred across socio‐economic and natural compartments of the Earth system after 1950. Among the observed changes, increase in fossil fuel burning has led to a significant accumulation of carbon dioxide (CO2) in the atmosphere.

Computational modeling of dynamic injector response in a Rotating Detonation Engine (RDE)

Applications in Energy and Combustion Science
Rotating Detonation Engines (RDEs) are a form of pressure gain combustion (PGC), offering a promising approach to increase the thermodynamic efficiency of a gas turbine combustor by utilizing a detonation-driven combustion process. In most RDEs, fuel and
