Oxygen Attachment Dissociation of Protonated Reserpine and Its Analogs
Rapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.ABSTRACT Rationale Carbon–carbon double bonds are ubiquitous structural motifs in natural products and pose a key challenge in locating their presence in analytes via MS‐based methods. Here, we use the alkaloid reserpine as a model system to examine whether OAD reactions can locate quaternary double bonds embedded in fused multicyclic structures ...

AIChE Journal, Volume 72, Issue 7, July 2026.Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1947-1967, 25 July 2026.ABSTRACT Iterative solvers are advantageous for handling nonlinear structural analysis problems. The iterative solvers often require updating the stiffness matrix, which limits their application in static and pseudo‐dynamic hybrid simulations because: (1) updating the stiffness matrix of a system involving a physical specimen is challenging; (2 ...

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver
International Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Forecasting Count Data With Varying Dispersion: A Latent‐Variable Approach
Journal of Forecasting, Volume 45, Issue 4, Page 1985-2000, July 2026.ABSTRACT Count data, such as product sales and disease case counts, are common in business forecasting and many areas of science. Although the Poisson distribution is the best known model for such data, its use is severely limited by its assumption that the dispersion is a fixed function of the mean, which rarely holds in real‐world scenarios.
