Natural and technological interdependent systems have been shown to be highly vulnerable due to cascading failures and an abrupt collapse of global connectivity under initial failure. Mitigating the risk by partial disconnection endangers their functionality. Here we propose a systematic strategy of selecting a minimum number of autonomous nodes that guarantee a smooth transition in robustness....

This study provides a national profile of major work safety accidents in Malaysia, There have been many incidents over the years, causing loss hundreds lives. We intended to provide scientific basis for prevention measures and strategies reduce deaths.1, 2 
 Methods: is one shocking accident Malaysia beside “the highland tower collapse”. It remembered us that project costing millions dolla...

A series of changes mechanical properties such as fracture development, relaxation, collapse deformation, and strength decreasing the surrounding rock loess tunnels occur due to shearing immersing, will be prone engineering failures, including large fissure, ground collapse, landslide, lining cracking, seriously threatening construction operation safety tunnels. These problems are especially pr...

GRW theory offers precise laws for the collapse of the wave function. These collapses are characterized by two new constants, λ and σ. Recent work has put experimental upper bounds on the collapse rate, λ. Lower bounds on λ have been more controversial since GRW begins to take on a many-worlds character for small values of λ. Here I examine GRW in this odd region of parameter space where collap...

Limitation of disturbances, such as grazing and fire, is a key tool for nature reserve management and ecological restoration. While the role of these disturbances in shaping ecosystem structure and functioning has been intensively studied, less is known about the consequences of long-term prevention of grazing and fire. Based on a 31-year study, we show that relative biomass of the dominant gra...

We study lower and upper bounds on the parameters for stochastic state vector reduction, focusing on the mass-proportional continuous spontaneous localization (CSL) model. We show that the assumption that the state vector is reduced when a latent image is formed, in photography or etched track detection, requires a CSL reduction rate parameter λ that is larger than conventionally assumed by a f...

Nowadays, as a result of increased terrorist and bomb attacks throughout the globe in the vicinity of strategic buildings, designing these structures against impact loads, particularly the blast-related ones, has been taken into more consideration. The current procedure for designing the structure against an explosion is a design against the local failure of the current elements in the first st...
