Persistence discontinuity in disordered contact processes with long-range interactions [PDF]

open access: greenJournal of Statistical Mechanics: Theory and Experiment, 2020
We study the local persistence probability during non-stationary time evolutions in disordered contact processes with long-range interactions by a combination of the strong-disorder renormalization group method, a phenomenological theory of rare regions,

Geological discontinuity persistence: Implications and quantification [PDF]

open access: greenEngineering Geology, 2018
Persistence of geological discontinuities is of great importance for many rock-related applications in earth sciences, both in terms of mechanical and hydraulic properties of individual discontinuities and fractured rock masses. Although the importance of persistence has been identified by academics and practitioners over the past decades ...

Forensic Excavation of Rock Masses: A Technique to Investigate Discontinuity Persistence [PDF]

open access: hybridRock Mechanics and Rock Engineering, 2017
True persistence of rock discontinuities (areas with insignificant tensile strength) is an important factor controlling the engineering behaviour of fractured rock masses, but is extremely difficult to quantify using current geological survey ...

Quantifying discontinuity orientation and persistence on high mountain rock slopes and large landslides using terrestrial remote sensing techniques [PDF]

open access: goldNatural Hazards and Earth System Sciences, 2009
This paper describes experience gained in the application of terrestrial digital photogrammetry and terrestrial laser scanning for the characterization of the structure of high mountain rock slopes and large landslides.

Automatic Mapping of Discontinuity Persistence on Rock Masses Using 3D Point Clouds [PDF]

open access: closedRock Mechanics and Rock Engineering, 2018
Finding new ways to quantify discontinuity persistence values in rock masses in an automatic or semi-automatic manner is a considerable challenge, as an alternative to the use of traditional methods based on measuring patches or traces with tapes. Remote sensing techniques potentially provide new ways of analysing visible data from the rock mass.

Amnesty Policy and Elite Persistence in the Postbellum South: Evidence from a Regression Discontinuity Design [PDF]

open access: greenJournal of Historical Political Economy, 2021
This paper investigates the impact of Reconstruction-era amnesty policy on the officeholding and wealth of elites in the postbellum South. Amnesty policy restricted the political and economic rights of Southern elites for nearly three years during ...

The Effects of Financial Aid Loss on Persistence and Graduation: A Multi-Dimensional Regression Discontinuity Approach [PDF]

open access: greenEducation Finance and Policy, 2021
For years Georgia's HOPE Scholarship program provided full tuition scholarships to high-achieving students. State budgetary shortfalls reduced its generosity in 2011.

The Returns to College Persistence for Marginal Students: Regression Discontinuity Evidence from University Dismissal Policies [PDF]

open access: greenJournal of Labor Economics, 2016
We estimate the returns to college using administrative data on both college enrollment and earnings. Exploiting that colleges dismiss low-performing students on the basis of exact GPA cutoffs, we use a regression discontinuity design to estimate the ...

Structural and Geomechanical Analysis of Natural Caves and Rock Shelters: Comparison between Manual and Remote Sensing Discontinuity Data Gathering

open access: yesRemote Sensing, 2023
The stability of many shallow caves and rock shelters relies heavily on understanding rock discontinuities, such as stratification, faults, and joints.

Regularization of the Boundary Equilibrium Bifurcation in Filippov System with Rich Discontinuity Boundaries

open access: yesAxioms
This paper studies a particular type of planar Filippov system that consists of two discontinuity boundaries separating the phase plane into three disjoint regions with different dynamics. This type of system has wide applications in various subjects. As
