Reconstructing the Thermal Green Functions at Real Times from Those at Imaginary Times
By exploiting the analyticity and boundary value properties of the thermal Green functions that result from the KMS condition in both time and energy complex variables, we treat the general (non–perturbative) problem of recovering the thermal functions at real times from the corresponding functions at imaginary times, introduced as primary objects in the Matsubara formalism. The key property on...

SEATTLE – Aviation Partners announced that as of 2:56 pm PST on Sunday, January 15, 2012 its blended winglets have saved the worlds commercial and business aircraft operators an estimated three billion gallons of jet fuel. This represents a global reduction in CO2 emissions of more than 32.2 million tonnes. Aviation Partners’ winglets are now flying on more than 5,000 individual airplanes, and ...

متن کاملReconstructing Stimulus-Driven Neural Networks from Spike Times
We present a method to distinguish direct connections between two neurons from common input originating from other, unmeasured neurons. The distinction is computed from the spike times of the two neurons in response to a white noise stimulus. Although the method is based on a highly idealized linear-nonlinear approximation of neural response, we demonstrate via simulation that the approach can ...
