Expressing the Behavior of Three Very Different Concurrent Systems by Using Natural Extensions of Separation Logic

open access: yes, 2009
Separation Logic is a non-classical logic used to verify pointer-intensive code. In this paper, however, we show that Separation Logic, along with its natural extensions, can also be used as a specification language for concurrent-system design. To do so,

Multiplex networks in metropolitan areas: generic features and local effects [PDF]

open access: yes, 2015
Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems of the coupling between them and we report in

Interfacial Adsorption Engineering Enables a Highly Utilized Zinc Anode With 99.9% Coulombic Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
When hydrated zinc ions are deposited onto Cu substrates at practical current densities, the modified Cu enables simultaneously compact zinc growth and suppressed hydrogen evolution. This regulatory effect originates from the superior adsorption of the modified Cu interface, which enhances zincophilicity and the hydrogen desorption barrier, thereby ...
