Partial Exact Controllability of a Nonlinear System

Revista Matemática Complutense, 1995
Let \(\Omega\) be a bounded open set in \(\mathbb{R}^n\) with sufficiently smooth boundary \(\Gamma\) and \(Q = (0,T) \times \Omega\), \(\Sigma = (0,T) \times \Gamma\). Consider the coupled equations: \[ u_{tt} - \Delta u + f(\theta) = 0 \quad \theta_t - \Delta \theta + g(u) = 0 \text{ in }Q \] with initial conditions \(u(0,x) = u_0 (x)\), \(u_t (0,x) =

Controllability of stochastic semilinear systems

Journal of Inequalities and Applications
In this paper, we demonstrate that the exact controllability concept is inappropriate for stochastic systems by proving the nonfulfillment of the coercivity inequality.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

On exact controllability for the Navier-Stokes equations [PDF]

ESAIM: Control, Optimisation and Calculus of Variations, 1998
Summary: We study the local exact controllability problem for the Navier-Stokes equations that describe an incompressible fluid flow in a bounded domain with control distributed in an arbitrary fixed subdomain. The result that we obtain in this paper is as follows.

Exact controllability for a Rayleigh beam with piezoelectric actuator

, 2023
In this paper, exact controllability for a Rayleigh beam with piezoelectric actuator is considered. Controllability results show that the space of controllable initial data depends on the regularity of the control function and the location of the ...

Time-harmonic electromagnetics with exact controllability and discrete exterior calculus

Comptes Rendus. Mécanique, 2023
In this paper, we apply the exact controllability concept for time-harmonic electromagnetic scattering. The problem is presented in terms of the differential forms, and the discrete exterior calculus is utilized for spatial discretization.

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

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.

Exact Controllability for Semilinear Wave Equations

Journal of Mathematical Analysis and Applications, 2000
The authors study the exact controllability of the system \[ {\partial^2 y(t, x) \over \partial t^2} - \Delta y(t, x) = f(y(t, x)) + \chi_\omega(x)u(t, x) \] in an \(n\)-dimensional domain \(\Omega\) with Dirichlet boundary condition, where \(\chi_\omega(x)\) is the characteristic function of a subdomain \(\omega \subseteq \Omega.\) Available results ...
