Some physical implementation schemes of quantum computing -- such as those based on superconducting qubits, quantum dots, and cold atoms -- can apply two-qubit gates only on certain pairs of qubits. O...
近日,国际石油地质重要期刊《AAPG Bulletin》刊发了中国地质大学针对页岩储层孔隙连通性和润湿性方面的研究成果,文章第一作者是中国地质大学资源学院杨锐博士后,第一单位为中国地质大学资源学院构造与油气资源教育部重点实验室,中国地质大学资源学院何生教授、中国石油大学(华东)胡钦红教授为该论文共同通讯作者。
ATLANTA–Scientists at Georgia State University have rewired the neural circuit of one species and given it the connections of another species to test a hypothesis about the evolution of neural circuit...
Nowadays "colored notions of connectivity in graphs" becomes a new and active subject in graph theory. Starting from rainbow connection, monochromatic connection and proper connection appeared later. ...
Geographical surveys of genetic variation provide an indirect means of tracing movments made between marine populations by larvae and other propagules. Genetic markers can provide strong evidence that...
This paper consists of three parts, each devoted to a result due to J.-C. Yoccoz.The proofs are all somewhat modied, but they are also deeply in!uenced byYoccoz's work.
The second smallest eigenvalue of the Laplacian matrix L of a graph is called its algebraic connectivity. We describe a method for obtaining an upper bound on the algebraic connectivity of a family of...
There is growing consensus that life within the world's ocean is under considerable and increasing stress from human activities (Hutchings, 2000; Jackson et al., 2001). This unprecedented strain on bo...
Many marine species have small, pelagic early life stages. For those species, knowledge of population connectivity requires understanding the origin and trajectories of dispersing eggs and larvae amon...
Population connectivity is inherently bio-physical: it is determined by physical transport and dispersion, as well as biological processes such as timing of spawning, larval behavior, and mortality. K...
The combination of wide-ranging spatial and temporal scales associated with the oceanic environment, together with processes intrinsic to the biology of marine organisms, makes the quantitative study ...
Understanding the connectivity of marine populations is vital for conservation and fisheries management, particularly for the strategic design of reserve systems. A recent proliferation of molecular a...
The importance of larval dispersal to the population dynamics and biogeography of marine organisms has been recognized for almost a century (Hjort, 1914; Thorson, 1950). More recently, theoretical stu...
An understanding of the extent to which marine populations are connected by larval dispersal is vital, both to comprehend past impacts and future prospects for sustaining biodiversity. Marine populati...
Understanding dispersal pathways and population connectivity is an essential prerequisite for devising effective fishery management strategies in at least two critical ways. The first concerns the del...
