Adjointness in recursion

open access: yesAnnals of Pure and Applied Logic, 1986
In this paper the role of adjointness in understanding properties of computable functionals is described. The author begins by providing a new characterization of the completion functor into complete \(f_ 0\) spaces (defined by Yu. Ershov). The category of complete \(f_ 0\) spaces is shown to be a reflective subcategory of the category of \(f_ 0 ...

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

open access: yesChemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

Geological carbon dioxide storage in the German North Sea: Static‐to‐dynamic capacity refinement for a 10 Mt/y injection scenario

open access: yesDeep Underground Science and Engineering, EarlyView.
This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Criteria of mutual adjointness of proper extensions of linear relations [PDF]

open access: yesМатематичні Студії, 2013
In the paper the role of {an} initial object is played by a~couple$(L,L_0)$ of closed linear relations in a~Hilbert space $H$,such that $L_0 subset L$. Each closed linear relation $L_1(M_1)$such that $L_0 subset L_1 subset L$ (respectively $L^{ast}subset

Quantization of Polaritons Confined in Dielectric Structures

open access: yesLaser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Adjoint and self-adjoint differential operators on graphs

open access: yesElectronic Journal of Differential Equations, 1998
A differential operator on a directed graph with weighted edges is characterized as a system of ordinary differential operators. A class of local operators is introduced to clarify which operators should be considered as defined on the graph.
