Knots in Collapsible and Non-Collapsible Balls [PDF]
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 ...

Analysis of the Mechanism of Ground Fissures in the Nairobi–Malaba Railway Rift Valley Area in Kenya
During the rainy season from March to May 2018, four ground fissures were generated in the rift valley area along the first phase of the Nairobi–Malaba Railway in Kenya, among which the ground fissures B3 highway, DK76, and DK77 were larger in scale ...

Effect of Adding Fine Gravel and Cement on Settlement of Sabkha Soil [PDF]
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 ...

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 ...

We formalize and study a phenomenon called feature collapse that makes precise the intuitive idea that entities playing a similar role in a learning task receive similar representations. As feature collapse requires a notion of task, we leverage a simple but prototypical NLP task to study it.

Application of sand drain immersion tests on collapsible loess
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 ...

Collapsibility and microscopic mechanism of intact loess at different depths in Xining area
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

High concentration of soluble salt in coastal saline soil can dissolve soil particles to some extent. In this paper, the application of slag compound as a curing agent (referred to as SM) for dealing with dissolve collapsibility in saline soil is ...

Inferior Vena Cava Diameter and Collapsibility Index measurements by Ultrasound and its Correlation with Central Venous Pressure in Critically Ill Patients [PDF]
Background: Assessment of intravascular volume status is an essential for the diagnosis and management of critically-ill patients. Central venous pressure (CVP), is an invasive measure used for this purpose.
