Mechanics of Glenohumeral Instability
Clinics in Sports Medicine, 1991The glenohumeral joint is designed for mobility and is normally lax. It is stabilized in its midrange by its limited joint volume and concavity-compression. It is stabilized at the extremes of motion by its ligaments. An enhanced understanding of these stabilizing mechanisms helps us in the diagnosis and management of glenohumeral instability.

Instability Mechanisms in Cooperative Control
IEEE Transactions on Automatic Control, 2008We consider a motion coordination problem with second order agent dynamics and examine the closed-loop robustness with respect to switching topology, variation of link gain, and unmodeled dynamics. In each case, we illustrate with examples possible instability mechanisms and discuss under what conditions stability is maintained.

Dynamic instabilities as mechanisms for emergence
Developmental Science, 2006AbstractThat competences may emerge given appropriate environmental and behavioral context is a long‐standing theme in developmental research. Work in the motor domain, but also in cognitive development, has made it possible to transform this idea into a mechanistic account closely linked to empirical evidence.

Thermoelasticity and Mechanical Instabilities
1984The objectives of these lectures are: To suggest that time is ripe to revisit the whole field of the mechanical behavior of materials. This is a field relevant for its engineering and technological applications as well as for its economical implications: but the conventional approach to it turns out to be inadequate to face the complexity of the ...

Mechanisms of chromosome instability in cancers
Critical Reviews in Oncology/Hematology, 2006Most tumours arise through clonal selection and waves of expansion of a somatic cell that has acquired genetic alterations in essential genes either controlling cell death or cell proliferation. Furthermore, stability of the genome in cancer cells becomes precarious and compromised because several cancer-predisposing mutations affect genes that are ...
