Q-Chem is a general-purpose electronic structure package featuring a variety of established and new methods implemented using innovative algorithms that enable fast calculations of large systems on regular laboratory workstations using density functional and wave-function-based approaches. It features an integrated graphical interface and input generator, a large selection of functionals and co...

Aging as the process in which the built-in entropy decreasing function worsens as internal time passes. Thus comes our definition, “life is a one way flow along the intrinsic time axis toward the ultimate heat death, of denumerably manymetabolic reactions, each at local equilibrium in view of homeostasis”. However, our disposition is not of reductionismic as have been most of approaches, but it...

6 The GEOS-Chem global chemical transport model (CTM), used by a large atmospheric chemistry 7 research community, has been re-engineered to also serve as an atmospheric chemistry module for Earth 8 System Models (ESMs). This was done using an Earth System Modeling Framework (ESMF) interface 9 that operates independently of the GEOS-Chem scientific code, permitting the exact same GEOS-Chem 10 c...
