Optimal Reinsurance-Investment Problem under Mean-Variance Criterion with n Risky Assets
Discrete Dynamics in Nature and Society, 2020 Based on the mean-variance criterion, this paper investigates the continuous-time reinsurance and investment problem. The insurer’s surplus process is assumed to follow Cramér–Lundberg model.

Neuroprotection, EarlyView.Abstract Aim Aromatase is the key enzyme in the biosynthesis of 17β‐estradiol, the most potent estrogen, which has pleiotropic neuroprotective properties. Aromatase levels increase in the brain after stroke, and its gene variants increase susceptibility to stroke. This study aims to determine whether aromatase overexpression improves stroke outcome and

Collision Avoidance Problem of Ellipsoid Motion
Mathematics, 2022 This paper studies the problem of target control and how a virtual ellipsoid can avoid the static obstacle. During the motion to the target set, the virtual ellipsoid can achieve a motion under collision avoidance by keeping the distance between the ...

HJB-POD Feedback Control for Navier-Stokes Equations [PDF]
, 2016 In this report we present the approximation of an infinite horizon optimal control problem for the evolutive Navier-Stokes system. The method is based on a model reduction technique, using a POD approximation, coupled with a Hamilton-Jacobi equation which characterizes the value function of the corresponding control problem for the reduced system ...

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 583-595, March 2025.ABSTRACT Prior pharmacokinetic (PK) analysis revealed that increased alpha‐1‐acid glycoprotein (AAG) levels are associated with decreased imatinib unbound fraction in coronavirus disease 2019 (COVID‐19) patients. This study aimed to investigate the PK of total and unbound concentrations of imatinib and the metabolite N‐desmethyl imatinib in ...

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.Radiofrequency amplification by stimulated emission of radiation (RASER) of solutes was achieved via parahydrogen‐induced polarization (PHIP) and polarization transfer from the produced hyperpolarization donors to solutes via the intermolecular nuclear Overhauser effect (NOE).

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT In this paper, we consider the optimal control problem for an unknown continuous‐time nonlinear system, and present a framework that integrates model‐based and model‐free methods to solve it. Each approach offers distinct advantages: model‐based techniques provide offline synthesis and data efficiency, while model‐free procedures excel at ...
