The adoption of axially oriented line illumination patterns for fluorescence excitation in small animals for fluorescence surface imaging (FSI) and fluorescence optical tomography (FOT) is being investigated. A trimodal single-photon-emission-computed-tomography/computed-tomography/optical-tomography (SPECT-CT-OT) small animal imaging system is being modified for employment of point- and line-l...

The term ‘‘floating shoulder ’’ was introduced by Herscovici in 1992 [1], charactered by ipsilateral scapular neck and clavicular shaft fractures. The definition of ‘floating shoulder’’ has been criticized by many authors, and the widely accepted definition is a double disruption of the superior suspensory shoulder complex (SSSC) [2-5]. SSSC is a bony/soft tissue structure, playing important ro...

We perform a stability analysis for a fluid-structure interaction (FSI) problem in which a spherical elastic shell or membrane is immersed in a 3D viscous, incompressible fluid. The shell is an idealized structure having zero thickness, and has the same fluid lying both inside and outside. The problem is formulated mathematically using the immersed boundary framework in which Dirac delta functi...

Many hadron production reactions give rise to significant ⊥ single-spin asymmetries (SSA) which persist at high energies. For example, hyperons produced in hadronic collisions typically show a large polarization perpendicular to the production plane. More recently, the HERMES collaboration found a significant SSA (left-right asymmetry in the transverse momentum distribution of the produced meso...

This work presents recent advances in visualizing multi-physics, fluid-structure interaction (FSI) phenomena in cerebral aneurysms. Realistic FSI simulations produce very large and complex data sets, yielding the need for parallel data processing and visualization. Here we present our efforts to develop an interactive visualization tool which enables the visualization of such FSI simulation dat...

The objective of the study is to investigate numerically the fluid-structure interactions (FSI) in a patient-specific arteriovenous fistula (AVF) and analyze the degree of complexity that such a numerical simulation requires to provide clinically relevant information. The reference FSI simulation takes into account the non-Newtonian behavior of blood, as well as the variation in mechanical prop...

Static feature-specific imaging (SFSI), where the measurement basis remains fixed/static during the data measurement process, has been shown to be superior to conventional imaging for reconstruction tasks. Here, we describe an adaptive approach that utilizes past measurements to inform the choice of measurement basis for future measurements in an FSI system, with the goal of maximizing the reco...

We develop a numerical method for simulating coupled interactions of complex floating structures with large-scale ocean waves and atmospheric turbulence. We employ an efficient large-scale model to develop offshore wind and wave environmental conditions, which are then incorporated into a high resolution two-phase flow solver with fluid-structure interaction (FSI). The large-scale wind-wave int...

This study aims to investigate appropriate treatment methods for floating shoulder injury (FSI). Fiftysix FSI patients treated from February 2006 to August 2014 were enrolled, and divided into three groups: a nonsurgical treatment group (Group A), a surgical treatment with single clavicular fixation group (Group B), and a surgical treatment with combined clavicular and scapular fixation group (...

The study of pion production and the effects final state interactions (FSI) are important for data analysis in all neutrino experiments. For energies at which current experiments being operated, a significant contribution to is made by resonance process. After its production, if absorbed nuclear matter, event may become indistinguishable from quasi-elastic scattering process acts as background....
