Analytical Ultracentrifugation in Aotearoa: A Brief History of the Technique and its Place Among Other Tools Used to Investigate Biomolecular Interactions

Journal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.
Analytical ultracentrifugation (AUC) is a powerful and versatile tool for studying biomolecular interactions. The purpose of this commentary is to provide foundational knowledge of the technique and its uses through the presentation of two case studies in which AUC provides key data to answer research questions.

Rapid and efficient quality control analysis of isolated mitochondria by interferometric light microscopy

VIEW, Volume 7, Issue 4, August 2026.
Mitochrial transplantation is a promising therapy to restore energy in damaged cells, but it lacks fast and reliable methods to assess mitochondrial quality before use. In this study, we used a label‐free imaging technique called interferometric light microscopy to rapidly measure the size and concentration of isolated mitochondria.

Integrating experimental and observational approaches facilitates scaling species interactions to biodiversity patterns

Functional Ecology, Volume 40, Issue 8, Page 2421-2435, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract To investigate how niche and fitness differences determine the outcome of species interactions and shape local biodiversity patterns, research has typically focused on either simplified experimental systems that test specific mechanisms or observational studies where ...

Fractional Gaussian Noise: Projections, Prediction, Norms

Fractal and Fractional
We examine the one-sided and two-sided (bilateral) projections of an element of fractional Gaussian noise onto its neighboring elements. We establish several analytical results and conduct a numerical study to analyze the behavior of the coefficients of ...

The Debt‐Equity Spread

The Journal of Finance, Volume 81, Issue 4, Page 2005-2062, August 2026.
ABSTRACT We propose a measure of the valuation gap between debt and equity—debt‐equity spread (DES)—based on the difference between actual and equity‐implied credit spreads. DES predicts cross‐sectional stock and bond returns in opposite directions.

Integral inequality approach to existence and approximate controllability of higher-order Hilfer fractional stochastic inclusions with impulses and jumps

Journal of Inequalities and Applications
This paper presents an analytical investigation of a new class of higher-order Hilfer fractional stochastic differential inclusions with order α ∈ ( 1 , 2 ) $\alpha \in (1,2)$ and type β ∈ [ 0 , 1 ) $\beta \in [0,1)$ . The proposed framework incorporates

Combined phylogenetic and geographic data can predict plant–pest interactions with high accuracy

New Phytologist, Volume 251, Issue 4, Page 2107-2123, August 2026.
Schematic overview of the study pipeline. Summary Non‐native plant pests can pose major threats to biodiversity, with destructive ecological and economic consequences. The ability to predict future threats would allow limited resources to be concentrated on managing the most serious risks. We built a Bayesian model to predict hosts at risk from Agrilus,

Confidence Intervals for Price Discovery

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 742-764, August 2026.
ABSTRACT This paper discusses asymptotic and bootstrap confidence intervals for multivariate permanent‐transitory decompositions of cointegrated vector autoregressive I(1) systems, with a focus on price discovery. Alternative estimators of the permanent components are compared in terms of efficiency also under separable linear restrictions on the ...

Inference on Common Trends in a Cointegrated Nonlinear SVAR

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 658-676, August 2026.
ABSTRACT We consider the problem of performing inference on the number of common stochastic trends when data is generated by a cointegrated CKSVAR (a two‐regime, piecewise affine SVAR; Mavroeidis, 2021), using a modified version of the Breitung (2002) multivariate variance ratio test that is robust to the presence of nonlinear cointegration (of a known
