New approach to stochastic optimal control and applications to economics [PDF]
, 2005 This paper provides new insights into the solution of optimal stochastic control problems by means of a system of partial differential equations, which characterize directly the optimal control.

Axioms, 2022 The paper deals with an application of the direct scheme method, consisting of immediately substituting a postulated asymptotic solution into a problem condition and determining a series of control problems for finding asymptotics terms, for asymptotics ...

Optimal Control of an Obstacle Problem [PDF]
Applied Mathematics and Optimization, 1997 The author investigates optimal control problems governed by variational inequalities, and more, precisely the obstacle problem. Since the author adopts a numerical point of view, he first relaxes the feasible domain of the problem; then using both, mathematical programming methods and penalization methods, the author gets optimality conditions with ...

Novel Spreadsheet Direct Method for Optimal Control Problems
Mathematical and Computational Applications, 2018 We devise a simple yet highly effective technique for solving general optimal control problems in Excel spreadsheets. The technique exploits Excel’s native nonlinear programming (NLP) Solver Command, in conjunction with two calculus worksheet functions ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Nonessential functionals in multiobjective optimal control problems [PDF]
, 2007 We address the problem of obtaining well-defined criteria for multiple criteria optimal control problems. Necessary and sufficient conditions for an objective functional to be nonessential are proved.

ON THE LOCAL CONTROLLABILITY FOR OPTIMAL CONTROL PROBLEMS
Matematički VesnikThe authors consider the control system: \(\overset{.}{x}=f(x,u,t)\), \( x(t_{0})=x_{0}\), \(u(t)\in U(t)\), \(t\in \lbrack t_{0},t_{1}]\), where \(t\) is the time, \(x\in \mathbb{R}^{n}\) a state variable, \(x_{0}\) is fixed, and the control \(u(t)\in U(t)\) for a.a. \(t\in \lbrack t_{0},t_{1}]\). The set-valued mapping \(U:\mathbb{R}\rightrightarrows

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
