Subgrid-scale processes, such as cloud physics, are parameterized and inherently introduce uncertainty into models. Traditionally, the sensitivities of the model state to specific uncertain parameters are quantified through perturbations to a few selected parameters, limited by computational resources. Algorithmic Differentiation (AD) enables the efficient and simultaneous estimation of sensitivities for a large number of parameters, thereby overcoming the previous limitations and significantly enhancing the efficiency of the analysis. This framework provides an objective way to identify processes where more precise representations have the largest impact on model accuracy. AD-estimated sensitivities can also address the underdispersiveness of perturbed ensemble simulations by guiding the parameter selection or the perturbation itself. In our study, we applied AD to 169 uncertain parameters identified in the two-moment microphysics scheme of the numerical weather prediction (NWP) model ICON of the German Weather Service. This application of AD allowed us to evaluate the sensitivities of specific humidity, latent heating, and latent cooling along several thousand warm conveyor belt trajectories. This coherent, strongly ascending Lagrangian flow feature is crucial for the cloud and precipitation structure and the evolution of extratropical cyclones. The quantification of individual parameter sensitivities shows that only 38 parameters are of primary importance for the investigated model state variables. These parameters are associated with rain evaporation, hydrometeor diameter-mass relations, and fall velocities. Moreover, the parameter sensitivities systematically vary with different microphysical regimes, ascent behavior, and ascent stages of the WCB airstream. Finally, several parameters impact an extended region in the extratropical cyclone, illustrating the spatiotemporal consistency of cloud microphysical parameter uncertainty in the applied NWP model and microphysics scheme.</div></div>","PeriodicalId":48907,"journal":{"name":"Journal of Computational Science","volume":"89 ","pages":"Article 102614"},"PeriodicalIF":3.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the benefits, they have privacy and security issues because the communication between patients and service providers takes place generally over public channels. Several user authentication protocols using distributed ledger technology (DLT) have recently been proposed to address these issues in EHSs. However, many are still vulnerable to a single point of failure (SPoF), privacy, and security attacks. Besides, they suffered from high communication and computational costs. Therefore, in this paper, we proposed a user authentication protocol using DLT to avoid these issues. A Burrows-Abadi-Needham (BAN) logic proof method has been used to check the security of the proposed protocol and ensure it achieves the desired security goals. In addition, an informal security analysis has been conducted to verify its important security requirements. A formal security analysis has been performed via the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool and Real-or-Random (ROR) model for further security strength. The results demonstrate that the proposed user authentication protocol is SAFE against all types of Man-in-the-Middle (MitM) attacks, impersonation, replay, and forgery attacks. Finally, performance analysis has been performed and results show that it achieves better performance by consuming 29.63 % and 13.21 % less communication and computational overheads as compared to existing related user authentication protocols. The security and performance analysis make it a more appropriate choice for the EHSs.</div></div>","PeriodicalId":48907,"journal":{"name":"Journal of Computational Science","volume":"89 ","pages":"Article 102617"},"PeriodicalIF":3.1,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144168985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through various case studies involving gravity dams, the computational accuracy and efficiency of different PINN models are compared. The results show the following: (1) The EPINN model demonstrates superior solving capability and computational efficiency—it is approximately 20 times faster than the PINN model—when dealing with complex geometries and boundary conditions. Conversely, the PINN model achieves higher computational accuracy for simpler geometries, with its precision being approximately twice that of the EPINN model.

In particular, the PINN model achieves accurate inversion of material properties via extremely limited data samples, with errors of only 0.46 % for the elastic modulus <em>E</em> and 2.32 % for Poisson's ratio <em>μ</em>.
