An integrated platform for 2‐D and 3‐D optical and electrical mapping of arrhythmias in Langendorff‐perfused rabbit hearts

The Journal of Physiology, EarlyView.
Abstract figure legend Integrated multimodal platform for panoramic cardiac mapping in isolated heart experiments. On the left, an image of the experimental setup during data acquisition showing a Langendorff‐perfused rabbit heart surrounded by three optical cameras (CAM A, B and C) positioned 120° apart, each coupled with high‐power LEDs for panoramic

Flexible cubic spline interpolation [PDF]

, 1972
This report describes a simple, efficient, and flexible program for cubic spline interpolation in one dimension, suitable for inclusion in the ANL Subroutine Library and in an interactive timesharing system. Most of the cubic spline programs already available either restrict the boundary conditions to knowledge of the first derivative at both end ...

Hyperpolarized MRI Detects Increased [1‐13C]Pyruvate Metabolism in Early Liver Regeneration

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Hyperpolarized [1‐13C]pyruvate MRI detected increased pyruvate‐to‐lactate and pyruvate‐to‐alanine exchange during early liver regeneration following 70% partial hepatectomy in rats. These findings support the use of hyperpolarized MRI for noninvasive assessment of regenerative metabolism.

On the Prediction of pDNA Productivity Across Diverse Bioprocesses Using Ensemble Hybrid Models

Biotechnology and Bioengineering, Volume 123, Issue 7, Page 1771-1782, July 2026.
ABSTRACT The global demand for plasmid DNA (pDNA) is rapidly increasing due to its key role in the manufacture of mRNA vaccines and advanced therapy medicinal products (ATMPs). However, the reliance on suboptimal batch and/or fed‐batch processes, as well as the diversity and increasing complexity of plasmid constructs pose significant challenges during

Capturing Aleatoric Uncertainty in Climate Models

Environmetrics, Volume 37, Issue 5, July 2026.
ABSTRACT Internal climate variability arises from the climate system's inherently chaotic dynamics. Quantifying it is essential for climate science, as it enables risk‐based decision‐making and differentiates between externally forced change and internal fluctuations.

Quadratic and cubic spline interpolation

Journal of Approximation Theory, 1984
Let (k,m) denote the class of k degree interpolating polynomial splines whose interpolation conditions are given by mth derivative values. Here we study the (2,0) and (3,1) problems.

Semi‐Automatic Assessment of Crohn's Disease Activity by Combined Analysis of Bowel Lesions and Creeping Fat

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 302-314, July 2026.
ABSTRACT Purpose To develop and evaluate Crohn‐BOOST, an open‐source tool enabling semi‐automatic segmentation of intestinal lesions and creeping fat on magnetic resonance enterography (MR Enterography), and to assess whether quantitative metrics derived from these segmentations relate to radiological disease activity scored with simplified MaRIA ...

Assimilation of Satellite‐Based Forest Biomass, Productivity and Leaf Area Index in a Global Land Model Incorporating Parameter Spatial Variations and Age Effects

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Disturbances profoundly impact forest capacity for sequestering and storing carbon, and the recovery rates after disturbances vary geographically. Many terrestrial carbon models inadequately simulate the effects of forest disturbances on biomass due to their reliance on equilibrium assumptions, the absence of historical disturbance data, as ...

Estimating Distribution Range Shifts of the Japanese Alpine Butterfly Colias palaeno Induced by Historical Climate Fluctuations and the Crucial Role of Its Host Plant

Ecological Research, Volume 41, Issue 4, July 2026.
In this study, we used ecological niche models to quantify historical changes in the estimated distribution ranges of the alpine butterfly Colias palaeno and its host plant Vaccinium uliginosum in Japan. The results showed that temperature and host plant occurrence strongly influence the estimated distribution of C. palaeno.
