Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

Contractive Multivariate Zipper Fractal Interpolation Functions

Results in Mathematics
AbstractIn this paper we introduce a new general multivariate fractal interpolation scheme using elements of the zipper methodology. Under the assumption that the corresponding Read-Bajraktarevic operator is well-defined, we enlarge the previous frameworks occurring in the literature, considering the constitutive functions of the iterated function ...

Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Nonlinear Fractal Interpolation Functions Induced by General Integral Contractions

Fractal and Fractional
The development of fractal set theory has been strongly driven by the introduction of new classes of fractal sets, among which the attractors of iterated function systems (IFSs) play a central role.

Correlation Properties of Heart Rate Variability for Exercise Intensity Monitoring and Prescription During Constant‐Load Cycling: A Comparison With Traditional Physiological Variables

European Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT This study investigated the applicability of the short‐term scaling exponent alpha 1 of detrended fluctuation analysis (DFA‐a1) as a marker of internal load during constant‐load cycling. The aim was to explore DFA‐a1 dynamics across the moderate, heavy, and severe intensity domains and assess its utility for both monitoring and prescribing ...

Nonlinear Fractal Interpolation Functions Under Integral-Type Contractive Conditions

Fractal and Fractional
Given a finite set of interpolation data {(xi,yi)∈I×R,i=0,1,…,N}, I=[x0,xN], we construct a class of nonlinear fractal interpolation functions whose graphs are realized as attractors of appropriately defined iterated function systems.

SLAMS‐2.0: A Stochastic, Lagrangian Particle‐Resolving Modeling Framework for Investigating the Biological Carbon Pump

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Sinking biogenic particles drive the ocean biological carbon pump (BCP), yet the processes governing their formation, transformation, and fate remain poorly constrained and are difficult to represent with existing modeling frameworks. Traditional approaches either resolve particle populations as bulk distributions or simulate individual ...

Phospholipid Monolayers and Vesicular Membranes Show Only Minor Structural Changes After Interaction With α$\alpha$‐Synuclein at Low and Physiological Concentrations

ChemPhysChem, Volume 27, Issue 20, 28 October 2026.
The interaction of α$\alpha$‐synuclein with lipid membranes in the synapse is intensively discussed in view of pathologies of neurodegeneration. By X‐ray diffraction from monolayer, lipid vesicles, and synaptic vesicles at different α$\alpha$‐synuclein concentrations, structural changes of the membrane can be probed in response to the interaction.
