Introduction Recent successes achieved with reverse shoulder arthroplasty (RSA) have led to an expansion of its indications and an increase in the number of commercially available designs in the global marketplace. Despite these development efforts, little guidance exists regarding reverse shoulder test methods and little published data exists regarding reverse shoulder performance standards. A...

itotic spindle positioning involves a con-formational switch in LGN, the mammalian version of the invertebrate Pins protein, duces a spindle rocking that represents the first genetically manipulable model for studying spindle positioning in vertebrates. The switch operates via the opening of LGN, which can normally fold back onto itself. The unfolding is triggered by binding to either membrane-...

Abstract Studies of rocking motion aim to explain the remarkable earthquake resistance structures. State-of-the-art assessment methods are mostly based on planar models, despite ongoing efforts understand significance three-dimensionality. Impacts essential components motion. We present experimental measurements free-rocking blocks a rigid surface, focusing extreme sensitivity impacts geometric...

This paper illustrates the results of an experimental campaign performed on a scale prototype base dissipator called Mini Tribological ROCKing Seismic Isolation Device. device allows smooth, controlled and damped rocking by means frictional layers viscous elastic springs, which aim at decoupling frequencies superstructure, dissipating energy during motion re-centering system once external actio...

We demonstrate experimentally a gating ratchet with cold rubidium atoms in a driven near-resonant optical lattice. A single-harmonic periodic modulation of the optical potential depth is applied, together with a single-harmonic rocking force. Directed motion is observed as a result of the breaking of the symmetries of the system.

The emergence of microcarrier technology has brought a renewed interest in anchorage-dependent cell culture for high-yield processes. Well-known in vaccine production, microcarrier culture also has potential for application in other fields. In this work, two types of microcarriers were evaluated for small-scale monoclonal antibody (mAb) production by CHOK1 cells. Cultures (5 ml) of microporous ...
