Abstract Quasi-free scattering of electrons and protons has been extensively utilized in the past to study single-particle structure nuclei, clustering light short-range correlated nucleon–nucleon pairs nuclei. Recently, this approach applied inverse kinematics using hydrogen targets. The characteristic features reaction experimental challenges advantages inverse-kinematics experiments are summ...

Particle segregation is common in natural and industrial processes involving flowing granular materials. Complex, seemingly contradictory, phenomena have been observed for different boundary conditions forcing. Using discrete element method simulations, we show that of a single particle intruder can be described unified manner across flow configurations. A scaling relation the net force obtaine...

objectives: the purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (sis) and thirteen persons without it. methods: values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior tipp...

Abstract We review some older and more recent results concerning the energy particle distribution in ground states of heavy Coulomb systems. The reviewed are asymptotic nature: they describe properties many-particle systems limit a large number particles. Particular emphasis is put on models that take relativistic kinematics into account. While non-relativistic typically rather well understood,...

BACKGROUND Wear-related failures and instabilities are frequent failure mechanisms of total knee replacements. High-conforming designs may provide additional stability for the joint. This study analyzes the effects of a ligamentous insufficiency on the stability and the wear behavior of a high-conforming knee design. METHODS Two simulator wear tests were performed on a high-conforming total k...

Flapping wings are important in many biological and bioinspired systems. Here, we investigate the fluid mechanics of flapping wings that possess a single flexible hinge allowing passive wing pitch rotation under load. We perform experiments on an insect-scale (≈1 cm wing span) robotic flapper and compare the results with a quasi-steady dynamical model and a coupled fluid–structure computational...

During my fellowship, I was incorporated into the image group on the “Human Motion Imitation” (HUMIM) project. This project consists in proposing a human motion model implying different mathematical techniques. Consequently, this project implies different skills in computer science, human physiology, mechanics and physics, optimisation’s problems, differential geometry and statistics, and requi...
