Local equilibrium and the second law of thermodynamics for irreversible systems with thermodynamic inertia [PDF]

open access: yes, 2015
Validity of local equilibrium has been questioned for non-equilibrium systems which are characterized by delayed response. In particular, for systems with non-zero thermodynamic inertia, the assumption of local equilibrium leads to negative values of the

Long-Term Response to Subtotal Colectomy in Colonic Inertia

open access: yesJournal of Gastrointestinal Surgery, 2002
The purpose of this study was to determine the long-term outcome of patients who had previously undergone subtotal colectomy for severe idiopathic constipation at the University of Florida between 1983 and 1987. In addition, we aimed to determine whether preoperative motility abnormalities of the upper gastrointestinal tract are more common among those

Nuclear fission: The "onset of dissipation" from a microscopic point of view [PDF]

open access: yes, 2001
Semi-analytical expressions are suggested for the temperature dependence of those combinations of transport coefficients which govern the fission process. This is based on experience with numerical calculations within the linear response approach and the

Inertia, aspirations, and response to attainment discrepancy in design contests [PDF]

open access: yesR&D Management, 2016
The process of evaluating performance relative to aspirations is widely used by many studies of organizational and technological change. The standard performance feedback model argues that decision makers act in function of attainment discrepancy between performance and aspirations.

Negative optical inertia for enhancing the sensitivity of future gravitational-wave detectors [PDF]

open access: yes, 2010
We consider enhancing the sensitivity of future gravitational-wave detectors by using double optical spring. When the power, detuning and bandwidth of the two carriers are chosen appropriately, the effect of the double optical spring can be described as ...
