Allowing structures to rock during an earthquake can effectively provide base isolation at a relatively small cost. Rocking limits the shear demand and provides self-centering, but rocking response depends on energy dissipation caused by interaction with soil impacts re-centering. This paper addresses computational modeling of buildings that have either been designed beneath their foundation (f...

The seismic response assessment of rocking systems via Incremental Dynamic Analysis (IDA) is investigated, focusing on the issues that arise in analysis and postprocessing stages. Rocking IDA curves generally differ from those hysteretic structural due to (i) frequent appearance resurrections; (ii) their highly weaving non-monotonic behavior; (iii) overall high variability. Hence, including or ...

This paper investigates both experimentally and theoretically the free rocking of a prismatic block supported by a stationary , horizontal foundation: the block is tilted, almost to the point of overturning, and released from this position. It is shown that the standard mathematical model for this problem is often inaccurate. A critical review of the implicit assumptions behind the standard mod...

Abstract Introduction Passive rhythmic movement–rocking – is found to enhance sleep, particularly in infants and young wild type (WT) mice. Rocking can potentially sleep at all ages, with the added benefit of being non-invasive, easy translate for human use, negligible side effects. Furthermore, enhancement tools should be especially valuable patients disturbances, a pervasive feature age-relat...

Patients who undergo abdominal surgery experience a phenomenon commonly called postoperative ileus (POI). Standard of care requires patients to get out of bed, sit in a chair, and begin ambulating the first postoperative day. No evidence supports standard care activities reduce POI duration. Rocking-chair motion has shown promise in reducing POI duration. Sixty-six participants were randomized ...

The functions of dance and music in human evolution are a mystery. Current research on the evolution of music has mainly focused on its melodic attribute which would have evolved alongside (proto-)language. Instead, we propose an alternative conceptual framework which focuses on the co-evolution of rhythm and dance (R&D) as intertwined aspects of a multimodal phenomenon characterized by the uni...
