Investment and Instability [PDF]
Although recet research has repeatedly found a negative association between investment and socio-political instability (SPI), the existence and direction of causality between these two variables has not yet been investigated. We construct an index of SPI

Mechanisms of cadmium induced genomic instability
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2012 Cadmium is an ubiquitous environmental contaminant that represents hazard to humans and wildlife. It is found in the air, soil and water and, due to its extremely long half-life, accumulates in plants and animals. The main source of cadmium exposure for non-smoking human population is food.

Mechanism and control of slope instability slip induced by overburden migration in side coal mining
Meitan kexue jishuDue to multiple factors, open pit mining will form a large amount of trapped coal on the side wall. With the end of internal discharge and reclamation, these trapped resources will be permanently lost, resulting in great waste.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Numerical identification of fast structural growth in stratified turbulence [PDF]
We investigate a type of instability observed in the presence of two counter rotating vortex columns in a highly stratfied fluid, Fr < 1. This instability causes the vortex columns to be bent and stretched out in the horizontal direction eventually ...
