The definition of a transparent software architecture is one of the key issues in the early development phases for complex distributed and reactive software systems. In this paper, we show how to derive an architecture systematically for systems with communication models based on broadcasting. Adequate graphical description techniques for capturing interaction requirements and logical component architectures for broadcasting systems are unavailable so far. We introduce an extension to UML's sequence diagrams to capture broadcasting scenarios. Furthermore, we present methodological steps for constructively deriving structural and behavioral aspects of the architecture under consideration from the captured scenarios.

Recent approvals of RNAi-based medications have rekindled interest in the industry, possibly strengthening the power of the therapeutic platform. Many groundbreaking research endeavors have offered new carrier architectures for carrying nucleic acid payloads. Because nucleic acids are charged negatively, utilizing complementary positively charged compounds sounds like a smart approach. The presence of such a cationic charge in the delivery vector, however, is a serious problem, increasing cytotoxicity. Charge-alteration-based approaches can address the evolving needs of nucleic acid-based therapies. Medication delivery platforms have become significantly smarter and safer.The research focuses on exciting recent advancements in management-switching technology. This study summarizes some of these fascinating possibilities, written by authors with special attention to the underlying physics of charge conversion processes. Charge reversal techniques are fairly new and are still in the early development phases. Translating such ideas would require significant investigation, including studies of safety, efficacy, and immunogenicity using relevant disease models.

Purpose A novel development process aims at finding solutions for lightweight stiffened shell structures and their efficient production. To respect the strong interdependency of structural design and production planning, particularly observed for composite structures, it is of high interest to start considering production effects in early development phases. This integrated approach requires an integrated representation of structure and production. The purpose of this study is to investigate the scope of relevant data and to find a structure for its representation. Design/methodology/approach The development task is analyzed and a system of so-called solution dimensions is presented, which covers all important aspects of stiffened shell structures and their production. An integrated product data model is developed to cover all of the solution dimensions. Findings The product data model consists of five coherent partial models. It is explained how these models are defined and how they are connected to each other. An academic example of an aircraft fuselage panel is used to demonstrate the definition process. It is shown how even complex structural concepts are defined systematically. Practical implications It is explained how this integrated product data model is used in a software project for the development of aircraft fuselage structures. Originality/value The presented approach for the definition and representation of stiffened shell structures enables the developer, e.g. of aircraft fuselage, to respect the crucial criterion of manufacturability from early development phases on. Further, new design approaches, e.g. as inspired by topology optimization, can be considered.
