Performance Evaluation of Lightweight Cryptosystems on Varied File Types in Cyber Physical Systems
No full textHospital environments are critical in the cyber world because the technologies used there directly impact patients' vital information and the continuity of healthcare. Digital infrastructures such as electronic health records, medical devices and communication systems pose a high risk to patient safety and data privacy. Therefore, cybersecurity in hospitals is a vital requirement to both protect patient privacy and ensure the uninterrupted continuity of healthcare services. Hospitals need secure and efficient encryption methods to protect patient privacy and meet operational requirements when handling large amounts of sensitive data. Traditional encryption methods pose challenges in terms of resource consumption, especially for devices with limited processing power and memory. This paper investigates ChaCha20 and Salsa20 lightweight encryption algorithms in healthcare based on factors such as processing time, memory usage and file type. Five different scenarios were created that can be encountered in a daily hospital environment. In these scenarios, the performance of lightweight encryption algorithms was analyzed. Instead of determining which algorithm is better, the study aims to show which algorithm gives better results in each scenario. ChaCha20 provides stable and reliable performance for small and medium-sized files in resource-constrained environments. Salsa20 performs well for large files and tasks that require fast processing. While both ciphers work effectively in different hospital environment scenarios, systems with cryptographic accelerators are found to significantly improve the performance and scalability of these algorithms. The findings of the study provide valuable insights for the selection and integration of lightweight encryption solutions suitable for different healthcare needs.https://doi.org/10.35378/gujs.164745

Development of Smart Textile from Sustainable and Antibacterial Poplar Fibers
No full textTextiles have been employed to cover human bodies for thousands of years, and now, scientists are combining textiles with advanced materials and electronic components to come up with wearable smart textile applications. In this study, untraditional and sustainable natural poplar fibers have been utilized to create a capacitive-based sensor. For this purpose, poplar fibers were converted to nonwoven pads via a spray coating method. Subsequently, these pads were coated with silver nanowires through a simple and scalable dip-coating process. The resultant conductive poplar pads were then isolated with a dielectric layer and used as a capacitive sensor. This sensor was integrated with a microcontroller, a GPS module, a Wi-Fi module, and a DC converter. Finally, the entire electronic components were embedded into a t-shirt. The act of gently pressing on a designated area on the t-shirt activates the sensing mechanism, prompting the system to dispatch an e-mail containing the user’s precise location to predetermined contacts, such as relatives, partners, or healthcare providers. The objective of this study is to develop a smart textile solution, especially for elderly individuals living independently with a focus on helping them during emergencies, such as heart attacks or brain hemorrhages. While demonstrating a novel application for the smart textile industry, an environmentally friendly study is also aimed at using sustainable poplar fibers. Moreover, it aims to showcase the bactericidal properties of poplar fibers against bacteria, opening up new possibilities for its usage in various applications in the future.https://doi.org/10.1021/acsomega.4c01149http://dx.doi.org/10.1021/acsomega.4c01149https://doaj.org/article/0247662dd482444b94082099f44677d

Hopf bifurcation in a generalized Goodwin model with delay
No full textGoodwin's model is a cornerstone in the study of dynamical systems within macroeconomics, explaining the interaction between employment ratio and wage share in a closed economy. Analogous to predator-prey dynamics in mathematical economics, the Goodwin model, despite its simplicity, effectively captures the periodic behavior of state variables over specific time intervals. By relaxing the initial assumptions, the model can be adapted to account for more complex economic scenarios. In this article, we study a higher-dimensional extension of the Goodwin model that incorporates variable capacity utilization and capital coefficient alongside employment ratio and wage share. In particular instances, the wage share and employment rate equations decouple from the overall system. For these cases, by incorporating a delay effect in the Phillips curve, we demonstrate that while the equilibrium of the generalized system remains stable within certain parameter domains in the absence of delay, the introduction of delay can induce a Hopf bifurcation, leading to periodic oscillations. We analytically derive the critical delay parameter value that destabilizes the equilibrium point via a Hopf bifurcation.30 pages, 12 figureshttps://doi.org/10.1016/j.matcom.2025.04.012https://dx.doi.org/10.48550/arxiv.2411.16383http://arxiv.org/abs/2411.16383https://zbmath.org/806840
Cratons are not all that stable!
No full textCratons are usually considered ‘old and stable’ geological units and, therefore, the do not receive as much consideration by geophysical data acquisition as active tectonic regions. However, abundant evidence shows that ‘stable’ cratons are modified substantially during their existence as demonstrated by geophysical data imaging cratonic lithosphere in several cases:(1) The Baltic Shield formed during the Svecofennian orogeny c. 1.7 Ga and its western parts were reworked by the Sveconorwegian/Grenvillian orogeny. Recent geophysical interpretations image a large body of crustal material in eclogite facies beneath the present Moho in the central shield. This body probably formed after the initial cratonization (Buntin et al., 2021).(2) The isopycnicity hypothesis proposes that a trade-off between composition and temperature of the lithospheric mantle maintains constant topography in cratons (Jordan, 1978) based on kimberlite data from South Africa. However, gravity data from Siberia shows that kimberlite pipes solely modify cratons in isostatic equilibrium (Artemieva et al., 2019). Therefore, kimberlite sampling is nonrepresentative, and the real composition of most cratonic mantle lithosphere is unknown.(3) Strong seismic anisotropy is observed in many cratons and is commonly attributed to the mantle due to frozen-in lithospheric features or asthenospheric flow. Recently it was demonstrated that a major part of the anisotropy resides in the crust of the Kalahara craton and that the fast axes are parallel to the strike of major dyke swarms and orogenic fabric (Thybo et al., 2019). This finding indicates significant craton modification by magmatic intrusion.(4) Modification by external stresses and induced magmatism may even split existing cratons.  Integrated interpretation of existing data and geodynamic modelling show that a linear sequence of volcanic harrats in the Arabian craton potentially represents the formation of a new plate boundary (Artemieva et al., 2022). It is probable that the extension in the northern Red Sea rift will jump to the volcanic lineament, which eventually will develop into new ocean spreading and effectively split the existing craton.ReferencesArtemieva, I.M.., Thybo, H. & Cherepanova, Y, 2019.
