For hadronic two-body decays of charmed mesons involving η or η′, resonance-induced finalstate interactions (FSI) that mimic the W -exchange or the W -annihilation topology can play an essential role. In particular, the decays D0 → Kη′ and D+ → π+η, which are largely suppressed in the absence of FSI, are enhanced dramatically by resonant FSI. It is stressed that the effect of resonant FSI is ne...

The fluid/structure interaction (FSI) investigations of stacked chip in encapsulation process of moulded underfill packaging using the two-way Coupling method with ANSYS Fluent and ANSYS Structural solvers are presented. The FSI study is executed with different aspect ratio of stacked chip on the mould filling during the encapsulation process. The simulation results in the FSI study is well val...

Parallel overlapping Schwarz preconditioners are considered and applied to the structural block in monolithic fluid-structure interaction (FSI). The two-level overlapping Schwarz method uses a coarse level based on energy minimizing functions. Linear elastic as well as nonlinear, anisotropic hyperelastic structural models are considered in an FSI problem of a pressure wave in a tube. Using our ...

Aseismic safety of dam involves people’s lives and properties, even has a great impact on national economic development. The key to this project is to have a fairly complete fluid-structure interaction (FSI) theory and a calculation method with a good accuracy. Therefore, focused on the FSI dynamic problem of gravity dam under seismic action, this paper presented the non-linear 2.5D dynamic the...

We discuss all contributions from Zweig-rule-satisfying SU(3)-symmetric inelastic FSI-induced corrections in B decays to ππ, πK, KK̄, πη(η′), and Kη(η′) . It is shown how all of these FSI corrections lead to a simple redefinition of the amplitudes, permitting the use of a simple diagram-based description, in which, however, weak phases may enter in a modified way. The inclusion of FSI correction...

A free semigroup with involution (FSI) is essentially the set of words over a given alphabet plus an operator which reverses words. The paper introduces equations in FSI and show that they are the right objects to deal with when studying the complexity of equations in free groups. On these lines, we generalize to FSI several results valid for word equations, like the overlapping lemma, the 2O(|...

The characteristics of physiological blood flow in human carotid arterial bifurcation model have been numerically studied using a fully coupled fluid-structure interaction (FSI) analysis. This computational model with the fluid-structure interaction is constructed to investigate the flow characteristics and wall shear stress in the carotid artery. As the flow begins to decelerate after the peak...

This retrospective study aimed at assessing the reliability of morphometric measurements performed on the frontal sinus using the frontal sinus index (FSI) for sex determination on cranio-facial and sinuses CBCT scans. 77 CBCT explorations were performed by Planmeca 3D Mid (Planmeca, Helsinki, Finland) and Romexis 3.6 software (Planmeca, Helsinki, Finland) on adult individuals. The FSI was dete...

The modeling of neutrino-nucleus interactions constitutes a challenging source systematic uncertainty for the extraction precise values neutrino oscillation parameters in long-baseline accelerator experiments. To improve such and minimize corresponding uncertainties, new generation detectors is being developed, which aim to measure complete final state particles resulting from interactions. In ...

The paper presents an application of the FSI technique to determine hemodynamics in the abdominal aorta (AA). To establish boundary conditions for the FSI study, MR anatomical data and 4D MRI velocity-mapping data (in three blood flow velocity directions and time) were collected to acquire realistic geometry of the AA and blood velocity. The mechanical parameters of the patient-specific aortic ...
