Optimal Portfolio Choice With Cross‐Impact Propagators

Mathematical Finance, EarlyView.
ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...

P2X3 receptor antagonism improves hindlimb blood flow during exercise in a conscious ovine model of hypertensive heart failure with preserved ejection fraction

The Journal of Physiology, EarlyView.
Abstract figure legend A preclinical large‐animal model of hypertensive heart failure with preserved ejection fraction (HFpEF) was used to examine the role of purinergic P2X3 receptor signalling during treadmill exercise. Animals were instrumented with either thoracic cardiac output and coronary flow probes or abdominal renal and hindlimb blood flow ...

Inverse problems for semilinear elliptic PDE with a general nonlinearity a(x,u)$a(x,u)$

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This article studies the inverse problem of recovering a nonlinearity in an elliptic equation Δu+a(x,u)=0$\Delta u + a(x,u) = 0$ from boundary measurements of solutions. Previous results based on first‐order linearization achieve this under a sign condition on ∂ua(x,u)$\partial _u a(x,u)$, and results based on higher order linearization ...

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Numerical solution of nonlinear Volterra–Fredholm integral equations using hybrid of block-pulse functions and Taylor series

Alexandria Engineering Journal, 2013
A numerical method based on an NM-set of general, hybrid of block-pulse function and Taylor series (HBT), is proposed to approximate the solution of nonlinear Volterra–Fredholm integral equations. The properties of HBT are first presented.

Selective Packaging of miR‐22 and miR‐29 Orthologues into Extracellular Vesicles of the Porcine Whipworm Trichuris Suis

Journal of Extracellular Vesicles, Volume 15, Issue 9, September 2026.
ABSTRACT Helminths modulate host immunity, and in this respect, the porcine whipworm Trichuris suis has been explored clinically as an immunotherapy for inflammatory diseases. T. suis secretes a complex mixture of excretory/secretory products (ESP), including extracellular vesicles (EVs), nanosized membranous particles with bioactive cargoes of lipids,
