Providing a decreasing congestion probability model for urban streets network [PDF]
Transport, 2006 Urban streets classification systems are the basis for defining function and, in turn, the design criteria for the world’s streets networks. The traditional classification systems have been based on the mobility and access functions of roads for motor ...

Integrating out the Dirac sea in the Walecka model [PDF]
, 2010 We derive a purely fermionic no-sea effective theory, featuring positive-energy states only for the Walecka model. In contrast to the so-called mean-field theory approach with the no-sea approximation, where the Dirac sea is simply omitted from the ...
