Mapping between dissipative and Hamiltonian systems [PDF]

open access: yes, 2010
Theoretical studies of nonequilibrium systems are complicated by the lack of a general framework. In this work we first show that a transformation introduced by Ao recently (J. Phys.

Fine‐Tuned Magnetic and Electrochemical Properties of a Series of Fe(II) Complexes with Asymmetric Jäger‐Type (N2O2)2− Ligands

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
Asymmetrically substituted Jäger‐type ligands and their Fe(II) complexes show additive optical and redox trends. Ketone donors promote spin‐crossover while ester donors stabilize the high‐spin state, yet bulk materials display unexpected transitions governed by molecular symmetry and packing. A series of seven new asymmetrically substituted Jäger‐type (

Voltage Stability Assessment Based on Modified Line Voltage Stability Index in the Presence of Renewable Energy Integration and Credible Contingencies

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
A modified line voltage stability index (MLVSI) is proposed to address limitations in the existing indices. The MLVSI is evaluated against Lmn, MVSI, and NCPI under varying load levels, renewable energy penetration, and contingency scenarios. It considers line resistance, power flow direction, and high‐loading events to identify critical lines and ...

Stochastic Dynamical Structure (SDS) of Nonequilibrium Processes in the Absence of Detailed Balance. III: potential function in local stochastic dynamics and in steady state of Boltzmann-Gibbs type distribution function

open access: yes, 2008
From a logic point of view this is the third in the series to solve the problem of absence of detailed balance. This paper will be denoted as SDS III. The existence of a dynamical potential with both local and global meanings in general nonequilibrium ...
