Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Accurately predicting solute transport remains a central challenge in hydrogeology due to limited data and multiscale subsurface heterogeneity. Fractional Brownian motion (fBm) is widely used to model the logarithm of hydraulic conductivity fields.

Computational study of permeability in cardboard coating layers
AIChE Journal, Volume 72, Issue 7, July 2026.Abstract We develop a virtual material structure model based on a combination of tessellations and Gaussian random fields for a coating layer of paperboard used for packaging and designed to facilitate printing on the surface. To fit the model to tomographic image data acquired using combined focused ion beam and scanning electron microscopy (FIB‐SEM),

On circulant weighing matrices
Australas. J Comb., 1998 A circulant weighing matrix \(W\) of order \(n\) with weight \(k\) is a square matrix of order \(n\) with elements from \(\{0,1,-1\}\) such that \(WW'= kI_n\) and in which each row (except the first row) is obtained by its preceding row by a right cyclic shift. Necessary conditions for the existence of such matrices are obtained and several of them are

A Preconditioned Majorization‐Minimization Method for ℓ2$$ {\ell}^2 $$‐ℓq$$ {\ell}^q $$ Minimization
Numerical Linear Algebra with Applications, Volume 33, Issue 3, June 2026.ABSTRACT The need to minimize a linear combination of an expression that involves an ℓq$$ {\ell}^q $$‐norm of a linear transformation of the computed solution and the ℓ2$$ {\ell}^2 $$‐norm of the residual error arises in image restoration as well as in statistics.

Interpolation with circular basis functions [PDF]
, 2006 In this paper we consider basis function methods for solving the problem of interpolating data over distinct points on the unit circle. In the special case where the points are equally spaced we can appeal to the theory of circulant matrices which ...

International Journal of Cancer, Volume 158, Issue 10, Page 2771-2783, 15 May 2026.What's New? Circulating nuclear DNA (cir‐nDNA)‐based assessment of minimal residual disease (MRD) offers powerful post‐surgery prognostic insight for stage III colon cancer (CC). Sparse knowledge of post‐surgical variations and origins in cir‐nDNA, however, has limited its clinical application.
