Wildfire Impacts on Slope Stability Triggering in Mountain Areas

open access: yesGeosciences, 2019
Landslides over steep slopes, floods along rivers plains and debris flows across valleys are hydrogeological phenomena typical for mountain regions. Such events are generally triggered by rainfall, which can have large variability in terms of both its ...

Entanglement Rates and the Stability of the Area Law for the Entanglement Entropy [PDF]

open access: yesCommunications in Mathematical Physics, 2016
We prove a conjecture by Bravyi on an upper bound on entanglement rates of local Hamiltonians. We then use this bound to prove the stability of the area law for the entanglement entropy of quantum spin systems under adiabatic and quasi-adiabatic evolutions.

Dynamic Response and Stability Analysis of High-Speed Railway Subgrade in Karst Areas

open access: yesIEEE Access, 2021
The increase in railway coverage significantly increased the railway mileage in karst areas. However, the fragile ecosystem in karst areas and weak mechanical performance in cavities cause hidden railway safety hazards.

The (in)stability of money demand in the Euro area [PDF]

open access: yes, 2010
The instability of standard money demand functions has undermined the role of monetary aggregates for monetary policy analysis in the euro area. This paper uses country-specific monetary aggregates to shed more light on the economics behind the instability of euro area money demand.

Preliminary Analysis of Slope Stability in Kuok and Surrounding Areas

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology, 2016
The level of slope influenced by the condition of the rocks beneath the surface. On high level of slopes, amount of surface runoff and water transport energy is also enlarged.

Analytical and Numerical Study on the Stability of Highway Subgrade with Embedded Loading Berm in Soft Soil Area

open access: yesApplied Sciences, 2022
Loading berm is an effective method for improving highway subgrade stability in soft soil areas. However, this method requires lots of construction space. It is not applicable in some areas with narrow construction spaces.
