An error in the computer program which evaluated nucleon spectra following the decay of Λ hypernuclei has been detected. The error affected the final state interaction (FSI) of the nucleons, reducing by a factor ten the nucleon-nucleon (NN) collision probability. When correcting the error, some results and conclusions of Ref. [1] have changed substantially. In this erratum we present the correc...
Abstract. The article presents data on the social characteristics of first sexual intercourse (FSI) among secondary school students in Slovenia, collected as part research project “Sexuality Secondary School Students Slovenia”. results show that for most respondents their FSI was a planned event occurring within an intimate partnership. Protective measures are used to considerable extent. There...
We examine effects of final state interactions (FSI) in kaon decays using a new scheme without the Omnés function, and show that while ∆I = 1/2 rule is impossible to be explained in terms of FSI alone, ′/ ∼ 16.5 × 10−4 is obtained through FSI, if the calculation is concerned only with the CP-violating parts. The ππ contribution to the mL −mS mass difference is shown to be about 14%, if the size...
We discuss the final state interaction effects at high energies via a multichannel N/D method. We find that the 2 by 2 charge–exchange final state interactions typically contribute an enhancement factor of a few times 10−2 in the B meson decay amplitudes, both for the real and the imaginary part. We also make some discussions on the elastic rescattering effects. PACS numbers: 11.55.Fv, 11.80.Gw...
Fluid–structure interaction problems in general are often too complex to solve analytically and so they have to be analyzed by means of experiments or numerical simulation. Studying these phenomena requires modeling of both fluid and structure. Many approaches in computational aero elasticity seek to synthesize independent computational approaches for the aerodynamic and the structural dynamic ...
In this thesis we focus on the numerical analysis and the development of e cient partitioned algorithms for uid-structure interaction (FSI) problems arising in hemodynamics. In particular we consider the mechanical interaction of the blood with the large arteries, with the cardiac valves and with the myocardium. In partitioned FSI procedures the coupling between the uid and the structure can be...
Previously, we introduced a computational procedure based on three-dimensional meshless generalized finite difference (MGFD) method and serial magnetic resonance imaging (MRI) data to quantify patient-specific carotid atherosclerotic plaque growth functions and simulate plaque progression. Structure-only models were used in our previous report. In this paper, fluid-stricture interaction (FSI) w...
Often objects are to be ranked. However, there is no measurable quantity available to express the ranking aim and to quantify it. The consequence is that indicators are selected, serving as proxies for the ranking aim. Although this set of indicators is of great importance for its own right, the most commonly used practice to obtain a ranking is an aggregation method. Any aggregation, however s...
In this talk we deal with the simulation of fluid-structure interaction (FSI) problems in hemodynamics, with the emphasis in data assimilation and simulation in physiological regimes.
Experiments have shown that flow in compliant microchannels can become unstable at a much lower Reynolds number than the corresponding rigid conduit. Therefore, it has been suggested wall's elastic compliance be exploited towards new modalities of microscale mixing. While previous studies mainly focused on local instability induced by fluid--structure interactions (FSIs) system, we derive one-d...
