Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?

Journal of Financial Research, Volume 49, Issue 1, Page 228-252, Spring 2026.
Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...

Environmental Gradients Decouple Demographic and Adaptive Connectivity in a Highly Mobile Coastal Marine Species

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Understanding how eco‐evolutionary processes shape genetic variation and persistence in marine species with highly variable recruitment dynamics and dispersal potential remains a fundamental challenge, particularly when considering the interplay between gene flow and local adaptation.

Multivariate Generalization of the Confluent Hypergeometric Function Kind 1 Distribution

International Journal of Mathematics and Mathematical Sciences, 2008
The confluent hypergeometric function kind 1 distribution with the probability density function (pdf) proportional to x_−1F11(α;β;−x),  x>0 occurs as the distribution of the ratio of independent gamma and beta variables.

The potato cyst nematode Globodera pallida overcomes major potato resistance through selection on standing variation at a single locus

New Phytologist, Volume 249, Issue 6, Page 3039-3059, March 2026.
Summary Globodera pallida poses a major threat to potato production, with management strategies primarily relying on genetic resistance. However, increasing virulence in field populations across Western Europe raises major concerns for G. pallida control.

Exotic Genetic Lineages Rapidly Replace Established Exserohilum turcicum Populations in the Swiss Rhine Valley

Plant Pathology, Volume 75, Issue 2, March–April 2026.
A metagenomic survey of northern corn leaf blight in Swiss maize revealed a temporal shift from a dominant European clonal lineage to genetically diverse tropical lineages between 2016–2017 and 2021–2022. Pool sequencing enabled cost‐effective monitoring and highlights changing pathogen epidemiology relevant for durable maize resistance breeding ...

Insights into glandular trichome biology from analysis of organ‐specific gene expression programmes in cannabis, hop and tomato

The Plant Journal, Volume 125, Issue 6, March 2026.
Significance Statement This study of three glandular trichome‐producing species (cannabis, hop and tomato) defines tissue‐specific transcriptomic atlases for five organs (trichome, flower, leaf, stem and root), providing co‐expression and gene regulatory networks and identifying candidate regulators of specialised metabolism in trichomes of each ...

On moments of the derivative of CUE characteristic polynomials and the Riemann zeta function

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract We study the derivative of the characteristic polynomial of N×N$N \times N$ Haar‐distributed unitary matrices. We obtain new explicit formulae for complex‐valued moments when the spectral variable is inside the unit disc, in the limit N→∞$N \rightarrow \infty$.

Self-Similar Solutions of a Multidimensional Degenerate Partial Differential Equation of the Third Order

Mathematics
When studying the boundary value problems’ solvability for some partial differential equations encountered in applied mathematics, we frequently need to create systems of partial differential equations and explicitly construct linearly independent ...

INTEGRALS OF CONFLUENT HYPERGEOMETRIC FUNCTIONS

Tamkang Journal of Mathematics, 1990
The moments of the weight functions $w(x)=e^{-x}x^\mu(\ln x)^\rho$, $\rho=0, 1, 2$, on $[0, \infty)$ with respect to the Confluent Hypergeometric function $\phi(a - n, c;x)$, $n = 0, 1, 2, \cdots$, are explicitly evaluated.
