It is just amazing that both of the cover time and the mean hitting time of a random walk on a finite graph, in which the vertex visited next is selected from the adjacent vertices at random with the same probability, are bounded by O(n) for any undirected graph with order n, despite of the lack of global topological information. Thus a natural guess is that a better transition matrix is design...

the historic environment is an irreplaceable asset representing the investment of centuries of skills and resources. it gives places a unique competitive advantage. most of it is in daily use; it is capable of an economic future. the opportunities for regenerating historic environment require both conservation and development motivators to keep a unique sense of the historic environment whilst ...

Satellite images have been systematically explored by archaeologists to detect crop marks, which are considered as a proxy for the identification of buried archaeological remains. Even though several existing algorithms are frequently applied, such as histogram enhancements and vegetation indices, the detection of crop marks still remains a difficult task, while the final interpretation results...

Glasses acquire their solid-like properties by cooling from the supercooled liquid via a continuous transition known as the glass transition. Recent research on soft glasses indicates that besides temperature, another route to liquify glasses is by application of stress that drives relaxation and flow. Here, we show that unlike the continuous glass transition, the failure of glasses to applied ...
