Management of Refractory and Difficult‐To‐Treat Inflammatory Bowel Disease: An Expert Opinion Review

JCC Plus, Volume 1, Issue 5, September 2026.
This expert opinion offers a practical framework for refractory and difficult‐to‐treat IBD: confirm inflammation objectively, distinguish pharmacologic from structural and functional disease, and then escalate. Across ten clinical questions, the evidence is often limited to case series, and the resulting statements are identified as expert opinion ...

Comparison Between Respiratory‐Triggered and Free‐Breathing Signal Acquisition Methods for Single‐Voxel Phosphorus Magnetic Resonance Spectroscopy of the Liver on a Clinical System

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 702-711, September 2026.
ABSTRACT Background The optimal protocol for clinical liver 31P‐magnetic resonance spectroscopy (MRS) remains unclear. Single‐voxel 31P‐MRS using image‐selected in vivo spectroscopy (ISIS) employs respiratory‐triggering (RT) or free‐breathing (FB) acquisition.

A PDES method preserving boundaries on dense disparity map reconstruction

, 2008
Over smoothness restricts the application of PDEs in the field of dense disparity map reconstruction, because disparity map reconstruction usually requires preserving discontinuousness in some areas such as the boundaries of objects.

Nitric Oxide in Cancer: Mechanisms, Dual Role, and Therapeutic Strategies

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Nitric oxide exerts concentration‐dependent dual roles in cancer, functioning as either a tumor promoter or suppressor. This review comprehensively examines NO's multifaceted regulation of tumor biology, including S‐nitrosylation signaling, metabolic reprogramming, immunemodulation, and therapy resistance, and highlights emerging therapeutic strategies

General introduction to "KAM for PDEs"

, 2019
It is well known that the phase space of a finite dimensional integrable system is filled by invariant tori; KAM theory ensures that most of them persist under small perturbation.

Accurate and Efficient Data‐Driven Partitioned Scheme for Coupled Heterogeneous Numerical Models

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT Heterogeneous numerical models (HNMs) combine conventional discretization modules such as finite elements with nonconventional data‐driven and reduced‐order modules. HNMs can improve computational efficiency and enable simulations of multi‐physics systems in which one or more constituent components lack first‐principles descriptions and must ...

Toward Robust Optimal Control of Chromatographic Separation Processes With Controlled Flow Reversal

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT Column liquid chromatography is an important technique applied in the production of biopharmaceuticals, specifically for the separation of biological macromolecules such as proteins. When setting up process conditions, it is crucial that the purity of the product is sufficiently high, even in the presence of perturbations in the process ...

Model Predictive Control of Gas Networks Based on Port‐Hamiltonian Formulations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT To efficiently compute optimal compressor actions in gas networks, we investigate port‐Hamiltonian models consisting of linear and a nonlinear model assumptions. The control actions are derived via adjoint‐based gradients that incorporate the constraints of the underlying optimization problem. We then present results from the implementation of
