relatively standard. Thus, when an abrupt change in one grid is detected, it means that the difference between the two states before and after the abrupt change of this moment has the biggest amplitude by comparing with the other moment. Taking fig. A3 for example, we know that both the two series have two abrupt changes in moment t1 and t2 respectively. However, when we detect the abrupt chang...

Impulse propagation across sudden expansions of excitable tissue has been shown to exhibit various forms of conduction disturbance on a macroscopic scale, ranging from small delays to unidirectional or complete conduction block. With the present study, we attempted to characterize systematically the dependence of impulse propagation on the geometry of the underlying excitable tissue on a micros...

Large, abrupt, and widespread climate changes with major impacts have occurred repeatedly in the past, when the Earth system was forced across thresholds. Although abrupt climate changes can occur for many reasons, it is conceivable that human forcing of climate change is increasing the probability of large, abrupt events. Were such an event to recur, the economic and ecological impacts could b...

Abrupt climate change The nonlinearity of the climate system may lead to abrupt climate change, sometimes called rapid climate change, abrupt events or even surprises. The term abrupt often refers to time scales faster than the typical time scale of the responsible forcing. However, not all abrupt climate changes need be externally forced. Some possible abrupt events that have been proposed inc...

Photonic crystals based on graphene plasmons (GPs) are highly tunable and can accurately control photonic transmission at the nanoscales. In this work, transfer matrix method (TMM) is introduced to study plasmonic crystal (GPC) with periodic surface conductivity in case of normal incidence. The introduction TMM after considering abnormal phase scattering abrupt interface gives an idea manipulat...
