Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,

Dynamic Mode Decomposition (DMD) for Low‐Latency Real‐Time Cardiac MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 623-634, August 2026.
ABSTRACT Purpose To demonstrate dynamic mode decomposition (DMD) for high spatiotemporal low‐latency online reconstruction in 2D real‐time cardiac MRI. Methods DMD was applied to 2D spiral balanced steady state free precession (bSSFP) real‐time adult and fetal cardiac MRI at 0.55 T, with data from 10 healthy adult volunteers (3F/7M; age: 21–49; BMI: 20–

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

open access: yesInternational 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 House Prices: The Role of Market Interconnectedness

open access: yesJournal of Forecasting, Volume 45, Issue 4, Page 1847-1877, July 2026.
ABSTRACT While the existing research uncovers interconnections between various housing markets, it largely ignores the question of whether such linkages can improve house price predictions. To address this issue, we proceed in two steps. First, we forecast disaggregated house price growth rates from Australia and China to determine whether ...

Decoding the Structural Complexity of Fungal α‐ and β‐Glucan Matrix via Statistical Analysis of Solid‐State NMR Chemical Shifts

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Solid‐state NMR combined with principal component analysis enables quantitative classification of fungal α‐ and β‐glucan architectures in intact cell walls, revealing conserved triple‐helical β‐1,3‐glucan conformations across species and predominantly bundled‐sheet α‐1,3‐glucan assemblies with condition‐dependent polymorphism. Statistical clustering of

Capital in Motion: Synthesizing the Circulation and Reproduction in a Multi‐Sector Growth Model

open access: yesMetroeconomica, Volume 77, Issue 3, Page 274-288, July 2026.
ABSTRACT This paper analyzes Capital in Motion (CIM) in a capitalist economy, based on Karl Marx's Capital, Volume 2. It examines the circuit of capital, distinguishing between stock and flow variables, and integrates a multi‐sector growth model that combines the circuit and turnover of capital with the reproduction scheme.

Actuation of Cell Layers in Three Dimensions

open access: yesAdvanced Materials, Volume 38, Issue 34, 17 June 2026.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the

Using Principal Components Analysis to Visualize Motion and Mitigate Artifacts in Dynamic Optical Coherence Tomography

open access: yesJournal of Biophotonics, Volume 19, Issue 6, June 2026.
We demonstrate that Principal Component Analysis (PCA) can be used in dynamic OCT to substantially reduce artifacts from strong specular reflections, isolate movement within the sample, and create thin, histology‐like images, thereby avoiding the need for complex, time‐consuming techniques used in clinical histopathology.

Quality Assessment and Predictive Modeling of Chickpea, Lentil and Camelina Yield: Effects of Nitrogen, Irrigation, Rainfed Conditions, and Intercropping Using Machine Learning Approaches

open access: yesLegume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Given increasing water scarcity, the need to reduce chemical inputs, and the growing demand for nutritionally valuable vegetable oils, identifying sustainable cropping systems for camelina production has become increasingly important. This study aimed to evaluate the combined effects of nitrogen application, irrigation regimes (irrigated and ...
