Ecosystem engineers are organisms that affect ecosystem state by modifying the physical habitats in which biological interactions occur. Such engineering effect depends on both for environmental transformation and persistency of engineered structures, but distinction has rarely been considered. Here, we examined their relative terms ecological resilience. We used a mathematical model coral reef...

Microgrids are used in many applications to power critical loads that have significant consequences if they lose power. Losing medical centers, water treatment plants, data national defense installations, airports, and other infrastructure can cause loss of money life. Although such microgrids generally reliable at providing stable power, their resilience disruption be poor. Common interruption...

Introduction: One of the necessary features to confront the COVID-19 pandemic is performance and resilience which causes nursing managers to have a wider perspective based on preventing preparation and reaction to the disaster. This study aims to evaluate the nursing perspectives on nursing management during the COVID-19 Pandemic. Methods: One hundred eighty-nine Iranian nurses working in a Co...

It has become increasingly evident that large scale systems such as clouds can be brittle and may exhibit unpredictable behavior when faced with unexpected disturbances. Even weak and innocuous disturbances can bring down the system inoperative and may introduce catastrophic disasters to the society. The goal of this research is to explore the fundamental principles and theories that govern clo...

The lessons learned from the Fukushima Daiichi accident have focused on preventive measures designed to protect nuclear reactors, and crisis management plans. Although there is still no end in sight to the accident that occurred on March 11, 2011, how engineers have handled the aftermath offers new insight into the capacity of organizations to adapt in situations that far exceed the scope of sa...

Living systems rely on complex networks of chemical reactions to control the concentrations of molecules in space and time. Despite the enormous complexity in biological networks, it is possible to identify network motifs that lead to functional outputs such as bistability or oscillations. One of the greatest challenges in chemistry is the creation of such functionality from chemical reactions....
