Some authors refer to the concept of instability also considering the so-called "clinical" or "functional" instability, in which no defect of the body architecture of the lumbar spine, and no excessive detectable translation or rotation are shown.
In order to ascertain the concept of instability, a free text search was conducted on the three keywords (mood, affect and emotion) to identify the most frequently used modifier words up to two words on either side of the keyword.
The search results were manually reviewed by TL, RP and MT and modifier words relevant to the concept of instability (including common misspellings) were selected for inclusion in a gazetteer for each of the three NLP applications (see online supplementary table S1).
The concepts of slope instability and pressure arch are introduced into the shape design of the lower and upper structures respectively.
This follows the wider recognition of a 'new paradigm' for understanding dryland pastoral systems drawing heavily upon concepts of ecosystem instability or 'disequilibrium ecological theory' (Behnke et al. 1993).
Next, we give an overview of the concepts of waves, instabilities, chaos and turbulence in the planetary exoplanetary environment based on our present knowledge of the solar-terrestrial environment.
In 1952, Turing [25] proposed the reaction-diffusion equation and described the concept of Turing instability.
Loder's work has been instrumental in changing our understanding and approach to the management of the condition when he introduced the concept of "slip instability", which was fundamental in better understanding certain aspects of the condition.
Steven Balbus of the University of Oxford and John Hawley of the University of Virginia are sharing the astronomy award for developing the concept of magnetorotational instability, which describes the turbulence of the accretion disks that surround astrophysical objects such as forming stars and supermassive black holes.
Loder's work has been instrumental in changing our understanding and approach to the management of the condition when he introduced the concept of "slip instability" and showed that avascular necrosis (AVN) developed in 47% of unstable slips but none of the stable slips.
