Versatile and Highly Efficient MRI Simulation of Arbitrary Motion in KomaMRI
Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1791-1803, March 2026.ABSTRACT Purpose To extend the KomaMRI simulator with motion capabilities that enable the simulation of both simple, parametrizable motion patterns and arbitrarily complex spin trajectories. Additionally, we introduce a novel file format for storing and sharing dynamic digital phantoms.

Optimal Control Applications and Methods, Volume 47, Issue 2, Page 498-510, March/April 2026.Optimal control combines state and adjoint equations, which yield the state (x$$ x $$) and adjoint (lambda) variables as a function of the control variables (u$$ u $$). This structure allows us to design strategies for iteratively updating the control variable, based on conjugate gradient (CG) or GMRES algorithms.

Optimal Control Applications and Methods, Volume 47, Issue 2, Page 570-588, March/April 2026.Implicit third‐order Peer two‐step methods that are superconvergent for variable stepsizes have the potential to significantly improve the efficiency of solving large‐scale ODE‐constrained optimal control problems. These include real‐world applications in medical treatment planning for prostate cancer, such as the design of effective three‐dose drug ...

Control Effectiveness of Vortex Generators in High‐Speed Flows in Off‐Design Conditions
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT In aerospace transportation and propulsion systems, shock‐induced flow separation has strong detrimental effects on the aerodynamic behavior and performance. To alleviate these effects, separation control is necessary. A commonly pursued approach uses vortex generators (VG) of different design to increase the momentum transfer within the ...

Methods Based on Polynomial Chaos for Quadratic Delay Differential Equations With Random Parameters
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT We consider systems of delay differential equations (DDEs), including a single delay and a quadratic right‐hand side. In a system, parameters are replaced by random variables to perform an uncertainty quantification. Thus the solution of the DDEs becomes a random process, which can be represented by a series of the generalised polynomial chaos.

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.Abstract Gelatinous zooplankton (GZ) have been proposed as a potentially important but largely overlooked contributor to the biological carbon pump. However, estimates of GZ‐derived carbon transfer efficiency to the ocean floor reflect uncertainties in key parameters that govern carbon export, leading to contrasting interpretations of the role of GZ in

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract Mangrove forests provide effective coastal protection by attenuating wave energy, yet quantifying wave‐vegetation interactions remains challenging due to vertically heterogeneous root structures and variable submergence conditions. This study advances phase‐resolving wave–vegetation modeling by integrating realistic, depth‐dependent Rhizophora
