Monetary Policy and Wealth Effects: The Role of Risk and Heterogeneity

The Journal of Finance, Volume 81, Issue 2, Page 1011-1052, April 2026.
ABSTRACT We study the role of asset revaluation in the monetary transmission mechanism. We build an analytical heterogeneous‐agents model with two main ingredients: (i) rare disasters and (ii) heterogeneous beliefs. The model captures time‐varying risk premia and precautionary savings in a setting that nests the textbook New Keynesian model.

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

The Linearized Korteweg–de Vries Equation on the Line With Metric Graph Defects

Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.
ABSTRACT We study the small‐amplitude linearization of the Korteweg–de Vries equation on the line with a local defect scattering waves represented by a metric graph domain adjoined at one point. For a representative collection of examples, we derive explicit solution formulas expressed as contour integrals and obtain existence and unicity results for ...

Travelling wave solutions in a delayed predator-prey diffusion PDE system point-to-periodic and point-to-point waves

IMA Journal of Applied Mathematics, 2011
Summary: We develop a new method of combining the singular limit argument and the singular perturbation technique to establish the existence of the point-to-periodic heteroclinic travelling wave solutions connecting an equilibrium and a periodic travelling wave solution for a delayed predator-prey diffusion partial differential equation (PDE) system ...
