Summary: Pharmacologic knowledge is crucial for pediatricians in conducting PK/PD studies and applying antimicrobial therapies in children. Due to the difficulties in conducting such studies, there is still a lack of antimicrobial PK/PD data in children. Population PK/PD analysis is considered a suitable methodology for conducting PK/PD studies in children with limited blood drug concentration data, and it also has clinical utility in providing individualized optimal dosages for patients with different conditions.

Summary: Inhaled drugs play a crucial role in treating lung pathologies, but difficulties persist in assessing lung concentrations and interpreting their therapeutic action. Understanding the PK/PD relationship is essential for predicting therapeutic effects, but challenges remain due to the complex structure of the lungs and physical interactions with drugs. New methods are improving our understanding of inhaled drugs, but regulatory readiness is still a concern, requiring continued reliance on plasma concentrations as a proxy for lung deposition.

Summary: This work establishes a methodology to estimate the fatigue life of an anisotropic structure under uncertainty for the first time, utilizing the statistical inference of the Equivalent Initial Flaw Size Distribution (EIFSD). The challenges of detecting small cracks and predicting their fatigue propagation are overcome by the concept of the EIFSD, combined with a highly efficient computational tool for fatigue modelling problems: The Dual Boundary Element Method (DBEM). The proposed methodology demonstrates accurate fatigue life estimation with small errors compared to the actual fatigue life.

Summary: This study presents a framework for estimating the initial investment cost and added weight of integrating a structural health monitoring (SHM) system into an aircraft. The framework breaks down the sensorization activities and costs using wired or printed diagnostic film approaches, and considers the difference between manual and remote data acquisition. Based on a case study of a regional aircraft composite fuselage, there is a trade-off between cost and weight for different SHM options. These estimations capture the characteristics of each system and can be used in cost-benefit analyses for selecting the most suitable configuration.

Summary: This paper investigates the influence of internal defects, including active phase texture, CNT agglomerations, and interfacial damage, on the piezoelectric performance of composites. The study reveals that interfacial damage significantly affects the piezoelectric constants related to normal strain modes, while the constants related to shear strain remain unchanged. Near the percolation threshold of CNTs, there is a notable improvement in the piezoelectric response. The optimal texture and CNT volume fraction depend on the presence of interfacial damage.

Summary: This paper presents a Method of Fundamental Solutions (MFS) combined with Erdogan's solutions for Functionally Graded Materials (FGM) to analyze 2D fracture problems under static and dynamic loads. Erdogan derived analytical solutions for a pair of static concentrated forces in an infinite isotropic plate with a straight cut. The contribution of non-homogeneity in equilibrium equations is treated as body forces and requires domain integrals based on Erdogan's fundamental solutions. In dynamic cases, Laplace transformation and Durbin inversion technique are used to determine time-dependent variables such as stress intensity factors. Numerical domain integrals are obtained using the sub-region technique. The accuracy of MFS is demonstrated through four numerical examples and comparisons with different numerical approaches are performed.

Summary: A multiscale method is proposed in this paper for modeling damage evolution at the meso and macro scales in plain woven composites. The method employs an averaging theorem to couple macro and micro-scale simulations, allowing simultaneous computations at both scales. The proposed method addresses computational challenges by using a non-local approach to construct the macro-micro interface and introducing machine learning meta-models to reduce computing effort. Experimental tests and comparison with existing criteria validate the accuracy and applicability of the proposed method.

Summary: Among the Structural Health Monitoring (SHM) systems, Guided Waves (GW) based ones have been increasingly investigated for their reliability in damage detection, low power consumption requirement, and capability in monitoring extended areas with fewer transducers. However, their use in real applications is still challenging. This research focused on the effects of GW propagation mechanisms in a composite plate at an elevated temperature of 65 degrees C using a validated Finite Element (FE) model. The decrease in GW propagation velocity at 65 degrees C was observed.
