Efficient Scheduling Algorithms for Multicore Cyclic Executives With Precedence and Exclusion Relations

Concurrency and Computation: Practice and Experience, Volume 38, Issue 5, March 2026.
ABSTRACT Cyclic executives (CEs) offer the advantage of ensuring complete determinism with minimal runtime overhead, often making them the preferred choice for safety‐critical real‐time systems. However, generating CEs for multicore processors while addressing task precedence and exclusion relations presents significant challenges.

Evaluating the Limitations of One‐Dimensional High‐Temperature Gas Chromatography ‐ FID for Wax Solution Analysis: A Systematic Study

Journal of Separation Science, Volume 49, Issue 3, March 2026.
ABSTRACT Wax deposition in petroleum systems is intrinsically connected with paraffin wax composition, yet their quantitative characterization by one‐dimensional high‐temperature gas chromatography with flame ionization detection (HTGC–FID), as prescribed by ASTM D5442, remains challenging.

Unraveling the effects of wet and dry areas on carbon emissions in an intermittent Mediterranean stream

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Stream hydrological regimes are increasingly altered by water extraction, land‐use change, and climate change, leading to prolonged streambed desiccation in many regions. These alterations significantly impact biogeochemical processes within stream networks.
