Final-state interaction effects in charmless Bu,d,s → PP decays are studied. We investigate the B 0 → π+π−, π0π0 rates and the Kπ direct CP violations, which lead to the so-called Kπ puzzle in CP violation. Our main results are as follows: (i) Results are in agreement with data in the presence of FSI. (ii) For B decays, the π+π− and π0π0 rates are suppressed and enhanced respectively by FSI. (i...

Pulses of fine sediment in gravel-bedded rivers can cause extensive fine sediment infiltration (FSI) into void spaces in coarse bed material, potentially altering river morphodynamics and aquatic ecosystems. Previous work suggests a conceptual model of FSI whereby FSI occurs to a limited depth as a function of the relative grain size of bed sediment compared with infiltrating sediment and is in...

in order to evaluation of the relationship among protein markers and traits such as proline content variation, quantum efficiency of photosystem ii and field viability index, 20 genotypes of barely were studied in a randomized complete block design in the greenhouse experiment. plants were transferred to springhouse at the four leaf stage and were located at the temperature of 4°c for three wee...

Static Feature-specific imaging (SFSI) employing a fixed/static measurement basis has been shown to achieve superior reconstruction performance to conventional imaging under certain conditions. In this paper, we describe an adaptive FSI system in which past measurements inform the choice of measurement basis for future measurements so as to maximize the reconstruction fidelity while employing t...

this study investigated the performance and aeroelastic characteristics of a wind turbine blade based on strongly coupled approach (two-way fluid structure interaction) to simulate the transient fsi1 responses of hawt2. aerodynamic response was obtained by 3d cfd-urans approach and structural response was obtained by 3d finite element method. aeroelastic responses of the blade were obtained by ...

In this paper, a general framework for the computational simulation of Fluid-Structure Interaction (FSI) problems involving rigid/flexible solids and multiphase flows is presented. The proposed methodology builds upon the Immersed Structural Potential Method (ISPM) developed by the authors [1, 2] for the simulation of single-phase FSI problems. Several numerical examples are presented to showca...

Aeroelastic simulations of a 2.3 MW wind turbine rotor operating in different complex atmospheric flows are conducted using high fidelity fluid–structure interaction (FSI) simulations. Simpler blade element momentum (BEM) theory based likewise for comparison, and measurements from field experiments used validation the Good agreement is seen between simulated measured forces. It found that flows...

A b s t r a c t We develop the Glauber theory description of final-state interaction (FSI) in quasielastic A(e, e ′ p) scattering. The important new effect is an interaction between the two tra-jectories which enter the calculation of FSI-distorted one-body density matrix and are connected with incoherent elastic rescatterings of the struck proton on spectator nucle-ons. We demonstrate that FSI...
