Non-equilibrium systems have steady-state distributions and non-steady dynamics
, 2020 We search for steady states in a class of fluctuating and driven physical systems that exhibit sustained currents. We find that the physical concept of a steady state, well known for systems at equilibrium, must be generalised to describe such systems ...

NON‐STEADY‐STATE ANALYSIS OF CELLULAR DEVELOPMENT
Cell Proliferation, 1974 ABSTRACTA discrete, compartmental, representation is proposed for cellular development. Equations describing the kinetics of cellular development (with or without cell proliferation) are derived in both differential and integral form.Using an integral formulation, a method is proposed for the computation of compartment transit times (maturation times ...

Evaluation of Soil Hydraulic Parameters Calculation Methods Using a Tension Infiltrometer
Soil Systems, 2022 In the present work, a review for the methodologies that have been proposed to calculate the main soil hydraulic properties, hydraulic conductivity (K) and sorptivity (S), at negative pressure heads near to saturation of the soil using a tension ...

Entanglement Evolution in the Presence of Decoherence [PDF]
, 2005 The entanglement of two qubits, each defined as an effective two-level, spin 1/2 system, is investigated for the case that the qubits interact via a Heisenberg XY interaction and are subject to decoherence due to population relaxation and thermal effects.

Frontiers in Earth Science, 2021 We present the results of an isotope-enabled reactive transport model of a sediment column undergoing active microbial sulfate reduction to explore the response of the sulfur and oxygen isotopic composition of sulfate under perturbations to steady state.

Non-steady-state extremely asymmetrical scattering of waves in periodic gratings [PDF]
, 2002 Extremely asymmetrical scattering (EAS) is a highly resonant type of Bragg scattering with a strong resonant increase of the scattered wave amplitude inside and outside the grating.

Non-equilibrium steady state of a driven levitated particle with feedback cooling
New Journal of Physics, 2015 Laser trapped nanoparticles have been recently used as model systems to study fundamental relations holding far from equilibrium. Here we study a nanoscale silica sphere levitated by a laser in a low density gas. The center of mass motion of the particle

Effects of system-bath entanglement on the performance of light-harvesting systems: A quantum heat engine perspective [PDF]
, 2015 We explore energy transfer in a generic three-level system, which is coupled to three non-equilibrium baths. Built on the concept of quantum heat engine, our three-level model describes non-equilibrium quantum processes including light-harvesting energy ...

Politics and GovernanceThe three pillars of society—democracy, the market, and science and technology—are not systems that guarantee survival. This is because they will cause “future failures” that will eventually impose heavy burdens on future generations.
