Controlled Feeding Facilitates the Development of a Robust Production Process for Terpolymeric Polyhydroxyalkanoates

Biotechnology Journal, Volume 21, Issue 6, June 2026.
Graphical Abstract and Lay Summary Cupriavidus necator NCIMB 11599 was cultivated with a fully automated pH–pO2‑dependent feeding strategy that enables controlled levulinic acid delivery and robust production of PHBVV terpolymer. The process was successfully transferred from 7.5 to 42‑L stirred‑tank reactors, maintaining PHA contents of ∼75% CDW and ...

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 615-632, June 2026.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Multiple Scattering Suppression in Heterogeneous Media: High‐Precision Imaging of Sleeve Grouting Defects Based on Elastic Reverse Time Migration

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.
