Opportunities and Challenges for Mexico-U.S. Cooperation in Ocean Sciences
Opportunities and Challenges Mexico-U.S. Cooperation Ocean Sciences
2015/8/5
In an academy-to-academy effort that is novel for the ocean sciences, a Mexico-U.S. Joint Working Group (JWG) on Ocean Sciences was created in 1995 by the U.S. National Research Council (NRC) and the ...
Introduction to this Special Issue on Strata Formation on European Margins: A Tribute to EU-NA Cooperation in Marine Geology
European Margins Strata
2015/7/29
n the early fall of 1998, we sat gazing over the coastal ocean that surrounds Sicily. Scientists from around the world had gathered to participate in a SEPM-IAS (Society for Sedimentary Geology-Intern...
Benefits of International Student Exchange and International Cooperation

2015/7/13
Since 2001, American and Taiwanese scientists have been conducting a series of six collaborative programs to explore ocean physics around Taiwan. Two of these programs, the Internal Waves in Straits E...
EARTH OBSERVATION IN SUPPORT OF SCIENCE AND APPLICATIONS DEVELOPMENT IN THE FIELD “LAND AND ENVIRONMENT”: SYNTHESIS RESULTS FROM THE ESA-MOST DRAGON COOPERATION PROGRAMME
Land and Environment scientific knowledge
2015/5/7
Dragon is a cooperation Programme between the European Space Agency (ESA) and the Ministry of Science and Technology (MOST) of the P.R. China. The Programme, initiated in 2004, focuses on the exploi...
Percolation threshold determines the optimal population density for public cooperation
Percolation threshold optimal population density public cooperation
2012/5/28
While worldwide census data provide statistical evidence that firmly link the population density with several indicators of social welfare, the precise mechanisms underlying these observations are lar...
Spectrum Leasing via Cooperation for Enhanced Physical-Layer Secrecy
Physical layer security secrecy capacity spectrum leasing Pareto boundary power gain region
2012/5/9
Spectrum leasing via cooperation refers to the possibility of primary users leasing a portion of the spectral resources to secondary users in exchange for cooperation. In the presence of an eavesdropp...
An Outer Bound for the Memoryless Two-user Interference Channel with General Cooperation
Information Theory Memoryless Two-user Interference Channel General Cooperation Outer Bound
2012/4/16
The interference channel models a wireless network where several source-destination pairs compete for the same resources. When nodes transmit simultaneously the destinations experience interference. T...
Cooperation is viewed as a key ingredient for interference management in wireless systems. This paper shows that cooperation has fundamental limitations. The main result is that even full cooperation ...
Robustness of Two Simple Rules for the Evolution of Cooperation on Regular Graphs
Evolutionary game theory evolution of cooperation interacting particle systems voter model perturbations voter model
2011/8/29
Abstract: We study two simple rules on finite graphs for the death-birth updating and the imitation updating discovered by Ohtsuki, Hauert, Lieberman, and Nowak [\emph{Nature} {\bf 441} (2006) 502-505...
Topological conditions of scale-free networks for cooperation to evolve
scale-free networks Topological conditions evolve cooperation
2011/7/7
We employ evolutionary game theory to study topological conditions of scale-free networks for the evolution of cooperation. We show that Apollonian Network (AN) is a perfect scale-free network, on whi...
Gaussian Broadcast Channels with an Orthogonal and Bidirectional Cooperation Link
Gaussian Broadcast Channels Orthogonal Bidirectional Cooperation Link
2010/11/24
This paper considers a system where one transmitter broadcasts a single common message to two receivers linked by a bidirectional cooperation channel, which is assumed to be orthogonal to the downlin...
Interference Alignment Through User Cooperation for Two-cell MIMO Interfering Broadcast Channels
Two-cell MIMO Interfering Broadcast Channels
2010/11/22
This paper focuses on two-cell multiple-input multiple-output (MIMO) Gaussian interfering broadcast channels (MIMO-IFBC) with $K$ cooperating users on the cell-boundary of each BS. It corresponds to a...
Emergence of cooperation with self-organized criticality
self-organized criticality Physics
2010/11/16
Cooperation and self-organized criticality are two main keywords in current studies of evolution. We propose a generalized Bak-Sneppen model and provide a natural mechanism which accounts for both ph...
Theory of cooperation in a micro-organismal snow-drift game
Theory micro-organismal snow-drift game
2010/11/12
We present a mean field model for the phase diagram of a community of micro-organisms, interacting through their metabolism so that they are, in effect, engaging in a cooperative social game. We show ...
Consequences of fluctuating group size for the evolution of cooperation
quences fluctuating group size evolution cooperation
2010/11/15
Studies of cooperation have traditionally focused on discrete games such as the well-known prisoner's dilemma, in which players choose between two pure strategies: cooperation and defection. Increasi...
