Bidiagonal Decompositions and High‐Accuracy Computations for Newton Collocation Matrices

Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.
ABSTRACT We consider a class of collocation matrices A$$ A $$ associated with the Newton basis of the space of polynomials of degree at most n$$ n $$, evaluated at a set of l+1≥n+1$$ l+1\ge n+1 $$ nodes. In the most general setting, we allow n$$ n $$ of these nodes to either coincide with or differ from those defining the Newton basis.

Persistent sheaf Laplacian analysis of protein stability and solubility changes upon mutation

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Genetic mutations frequently disrupt protein structure, stability, and solubility, acting as primary drivers for a wide spectrum of diseases. Despite the critical importance of these molecular alterations, existing computational models often lack interpretability and fail to integrate essential physicochemical interactions.

Monotone Clusters With Ordinal Interpretation

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT There has been a growing demand in various sectors, such as healthcare, finance, and social sciences, for clustering methods that not only find quality clusters in data but also provide inherent order among the clusters for better decision‐making and risk assessment. Traditional clustering methods, though effective at grouping data, often fall

FREQ‐NESS Reveals Age‐Related Differences in Frequency‐Resolved Brain Networks During Auditory Recognition and Resting State

Annals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.
We adapted the FREQ‐NESS pipeline to event‐related MEG data from 140 adults during a melody‐recognition task, revealing an age‐related reorganization of frequency‐specific brain networks. Younger adults showed task‐related reduction in the prominence of alpha networks, whereas older adults maintained prominent slower alpha networks (8.6–10.0 Hz) across

Heteroskedastic Structural Vector Autoregressions Identified via Long‐Run Restrictions

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 834-846, August 2026.
ABSTRACT A central assumption for identifying structural shocks in vector autoregressive (VAR) models via heteroskedasticity is the time‐invariance of the impact effects of the shocks. It is shown how that assumption can be tested when long‐run restrictions based on the cointegration structure of the variables are available for identifying structural ...
