The breakage of bonding between sand particles at a borehole wall usually precedes the borehole failure and it can be considered as a sign that the onset of the borehole collapse is imminent in granular formations.
The onset of rapid collapse of the Thwaites Glacier in West Antarctica is likely within the next 200 to 1000 years.
The impedance shift from the dorsal to ventral lung region during the decremental PEEP steps was due to the onset of more collapse at the dorsal site than at the ventral site at the PEEP levels applied, as shown by the individual impedance changes in the different ROIs.
When the parameters of interest are the onset of plate collapse and the associated fluid channel velocities, coupled CFD CSM simulations provide superfluous information.
The great cities that dominated Petén had fallen into ruin by the beginning of the 10th century with the onset of the Classic Maya collapse.

The paper presents a combined experimental analytical study of the onset of collapse, its localization and the subsequent progressive folding.
The collapse index, I c, shows an increasing trend with each subsequent column removal hence validating the normalized energy-based approach for defining the onset of progressive collapse.

When defining lung collapse, decreases both in oxygenation (first decrease by greater than 10% from a maximum after recruitment) [ 4, 8] and in compliance (maximum compliance) [ 5, 9] during a decremental PEEP trial consistently identified the onset of lung collapse, which in turn defines open-lung PEEP as the end-expiratory pressure before this collapse occurred.
