Summary: This study adopts a fluid-structure interaction model to investigate the performance of the valve after transcatheter aortic valve replacement (TAVR). By comparing different valve geometries, it was found that a certain model exhibited lower stress on the valve and stent, improving the reliability of the stent design and reducing the risk of thrombosis.

Summary: This paper presents the applications of the arbitrary Lagrangian-Eulerian (ALE) method on the regularized boundary integral method (RBIM) for simulating water wave transformation over complex topography and wave-structure interaction. RBIM computes the singular integrals of the source and doublet functions through coordinate transformation. The ALE approach is adopted to avoid distorted nodal distribution and to conveniently apply free-surface boundary conditions. The numerical method is validated through examples and the advantages of ALE-RBIM over MEL-BEM are shown.

Summary: Fluid-structure-interaction (FSI) modeling is crucial for academic and engineering purposes, but it remains a grand challenge in numerical modeling. This paper presents an effective monolithic approach, called immersed multi-material arbitrary Lagrangian Eulerian material point method (IALEMPM), for FSI problems with multi-material fluid flow and extreme structure deformation. The proposed method tracks interfaces implicitly and implements interface interactions by assembling nodal forces and momenta. Consistent time integration scheme, rezoning phase, and remapping phase are also established for consistent requirements throughout the simulation. Numerical examples demonstrate the effectiveness of IALEMPM in solving complex FSI problems.

Summary: This paper introduces a novel methodology for fluid-structure interaction simulations by integrating skeleton-based structural models with an Arbitrary Lagrangian-Eulerian formulation. The proposed approach enhances the existing models by considering geometric nonlinearity and inelastic material responses. The method is evaluated using benchmark problems and a new benchmark study is defined to evaluate the effects of nonlinearities in FSI simulations.

Summary: This article presents an adjoint fluid-structure interaction system in an arbitrary Lagrangian-Eulerian framework, based on a one-field finite element method. The key feature of this approach is automatic satisfaction of interface conditions and reduced problem size due to solving for only one velocity field. A velocity (and/or displacement)-matching optimization problem is considered by controlling a distributed force, solved using a gradient descent method and a stabilised Barzilai-Borwein method for faster convergence without additional evaluations.

Summary: In this paper, an arbitrary Lagrangian-Eulerian (ALE) framework is introduced into the conserved discrete unified gas-kinetic scheme (CDUGKS) to solve transonic continuum and rarefied gas flows with moving boundary. The proposed ALE-CDUGKS updates both the distribution function and the conservative flow variables, and it shows high computational efficiency for flows in both continuum and rarefied regimes. The method incorporates the potential energy double-distribution-functions framework and the circle equilibrium distribution function model for continuum flows, and introduces unstructured velocity-space mesh technique for rarefied flows to reduce computational load. The capability of the proposed ALE-CDUGKS for solving compressible moving boundary problems with rarefied gas effect is demonstrated through simulations of various test cases.

Summary: The study found that all tested soft contact lens materials exhibited nonlinear behavior under compression loading, showing noticeable changes in stress-strain behavior. The compression modulus of elasticity was on average 2.2 times higher than the tensile modulus of elasticity, and it is recommended to use nonlinear compression-based material models when investigating lens-handling off-eye.

Summary: The study aimed to develop a mild, enzyme-free chemical decellularization method while preserving the biomechanical properties of cartilage. Through experiments on porcine osteochondral tissue, it was found that freezing treatment could effectively decellularize the superficial and middle zones, but not the deep zone. Biomechanical analysis showed that decellularization had an impact on the elastic modulus, but not on other parameters.

Summary: This study presents a comparative methodology for investigating calcium phosphate deposits on different heart valve prostheses in vitro. It was found that decellularized porcine aortic valves showed slightly higher rates of calcification compared to glutaraldehyde-fixed ones, attributed to tissue modifications from the decellularization process. Octacalcium phosphate crystallites were preferentially deposited in high mechanical stress areas, indicating the importance of mechanical forces in tissue mineralization. The in vitro circulatory model developed in this study serves as a valuable pre-screening tool for understanding the calcification process of bioprosthetic and tissue-engineered valves under physiological mechanical load.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
