To Dye or Not to Dye: Unraveling the Impact of Surface Chemistry on Cerium Oxide Nanoparticles–Cell Interactions

open access: yesSmall Science, EarlyView.
Fluorescent dye labeling enables nanoparticle imaging but may subtly alter their surface chemistry and biological behavior. This study compares dye‐labeled and unlabeled cerium oxide nanozymes, revealing changes in cellular uptake kinetics without affecting their final intracellular fate. Combined fluorescence and label‐free electron microscopy imaging

Addressing Complexity in System of Systems With GraphRAG: An AI‐Driven Framework for Dynamic Data Integration

open access: yesSystems Engineering, EarlyView.
ABSTRACT System of Systems (SoS) environments are inherently complex, involving numerous operationally and managerially independent component systems with hidden interdependencies and frequent interactions based on unstructured data. In this paper, we propose using graphical Retrieval‐Augmented Generation (GraphRAG), a tool that combines large language

Mission Aware Cyber‐Physical Security

open access: yesSystems Engineering, EarlyView.
ABSTRACT Perimeter cybersecurity, while essential, has proven insufficient against sophisticated, coordinated, and cyber‐physical attacks. In contrast, mission‐centric cybersecurity emphasizes finding evidence of attack impact on mission success, allowing for targeted resource allocation to mitigate vulnerabilities and protect critical assets.

An Object Oriented Model of a Railway Safety-Related Control System

open access: yesCommunications, 2002
There is a variety of methods and formalisms usable for writing specifications of railway interlocking and signalling systems or their subsystems. To write a consistent technical specification means to make a model with a required level of precision ...

A Bibliometric Review of the INCOSE's Model‐Based Systems Engineering Roadmap

open access: yesSystems Engineering, EarlyView.
ABSTRACT Over the past decade, model‐based systems engineering (MBSE) has gained attention as an approach for managing system complexity, offering a shift from a document‐based to a model‐based approach. The International Council on Systems Engineering (INCOSE) sparked increasing interest when it introduced MBSE and its roadmap as part of its systems ...

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no
