Model evolution and system evolution

open access: yesJournal of Computer Science and Technology, 2000
In this paper we define an evolution mechanism with formal semantics using the metamodeling methodology [Geisler et al.98] based on dynamic logic. A remarkable feature of the metamodeling methodology is the ability to define the relation of intentional ...

Evolution of adrenoleukodystrophy model systems [PDF]

open access: yesJournal of Inherited Metabolic Disease, 2021
AbstractX‐linked adrenoleukodystrophy (ALD) is a neurometabolic disorder affecting the adrenal glands, testes, spinal cord and brain. The disease is caused by mutations in the ABCD1 gene resulting in a defect in peroxisomal degradation of very long‐chain fatty acids and their accumulation in plasma and tissues. Males with ALD have a near 100% life‐time

Monotone iterative technique for non-autonomous semilinear differential equations with nonlocal condition

open access: yesDemonstratio Mathematica, 2019
The objective of this article is to discuss the existence and uniqueness of mild solutions for a class of non-autonomous semilinear differential equations with nonlocal condition via monotone iterative method with upper and lower solutions in an ordered ...

Global Existence and Stability for Neutral Functional Evolution Equations with State-Dependent Delay

open access: yesNonautonomous Dynamical Systems, 2014
In this paper we prove the global existence and attractivity of mild solutions for neutral semilinear evolution equations with state-dependent delay in a Banach space.

Characterization and genomic analysis of an oceanic cyanophage infecting marine Synechococcus reveal a novel genus

open access: yesFrontiers in Microbiology, 2023
Cyanophages play a crucial role in the biogeochemical cycles of aquatic ecosystems by affecting the population dynamics and community structure of cyanobacteria. In this study, a novel cyanophage, Nanhaivirus ms29, that infects Synechococcus sp. MW02 was

Boundary Conditions for the Einstein Evolution System [PDF]

open access: yes, 2004
New boundary conditions are constructed and tested numerically for a general first-order form of the Einstein evolution system. These conditions prevent constraint violations from entering the computational domain through timelike boundaries, allow the ...
