, 2004 Collapsing over variables is a necessary procedure in much empirical research. Consequences are yet not always properly evaluated. In this paper, different definitions of collapsibility (simple, strict, strong, etc.) and corresponding necessary and sufficient conditions are reviewed and evaluated.

Evaluation of Aeolian Sand Collapsibility Based on Physical Indicators in the Mu Us Desert, China
Applied SciencesThe collapsibility of aeolian sand has hindered the development of oil and gas resources and the construction of oil and gas stations in the Mu Us Desert. This study considered aeolian sand on the southern edge of the Mu Us Desert as the research object.

Knots in Collapsible and Non-Collapsible Balls [PDF]
The Electronic Journal of Combinatorics, 2013 We construct the first explicit example of a simplicial 3-ball $B_{15,66}$ that is not collapsible. It has only 15 vertices. We exhibit a second 3-ball $B_{12,38}$ with 12 vertices that is collapsible and not shellable, but evasive. Finally, we present the first explicit triangulation of a 3-sphere $S_{18, 125}$ (with only 18 vertices) that is not ...

Effect of Adding Fine Gravel and Cement on Settlement of Sabkha Soil [PDF]
Engineering and Technology Journal, 2012 Sabkha soil is one of the many types of collapsible soils and in turn is on of the many types of problematic soils. This soil is totally having good engineering properties when dry ,i.e ,moderately bearing capacity with low settlement .But once are ...

Application of sand drain immersion tests on collapsible loess
Yantu gongcheng xuebao, 2018 With the further development of China's western development strategy, more and more projects are constructed in collapsible loess area. The loess area is characterized by wide distribution, large thickness and different strong collapsibilities and ...

, 2022 Contemporary rates of biodiversity decline emphasize the need for reliable ecological forecasting, but cur-rent methods vary in their ability to predict the declines of real-world populations. Acknowledging that stress acts at the individual level, and that it is the sum of these individual-level effects which drives popu-lations to collapse, shifts ...

, 2006 A description in the Jacobs and Langen domain is a set of sharing groups where each sharing group is a set of program variables. The presence of a sharing group in a description indicates that all the variables in the group can be bound to terms that contain a common variable. The expressiveness of the domain, alas, is compromised by its intractability.

Collapsibility and microscopic mechanism of intact loess at different depths in Xining area
Yantu gongcheng xuebao, 2019 The collapsibility of the intact loess at different depths in Xining area is studied through the laboratory immersion compression tests. Combined with the scanning electron microscopy (SEM) and the particle and crack image recognition and analysis system
