Threshold Phenomena and Interactions Between Receptors

open access: yesJournal of Cardiovascular Pharmacology, 1988
Threshold or subthreshold concentrations of serotonin can augment contractile responses of isolated blood vessels to other vasoconstrictor agents. This report presents a theoretical analysis of threshold facilitation and concludes that the amplifying effect of serotonin may result from the removal of a response threshold.

Observation of interaction induced blockade and local spin freezing in a NMR quantum simulator

open access: yesPhysical Review Research, 2021
We experimentally emulate interaction induced blockade and local spin freezing in two and three qubit NMR architecture. These phenomena are identical to the Rydberg blockade and Rydberg biased freezing. In Rydberg blockade, the simultaneous excitation of

Quantum criticality and population trapping of fermions by non-equilibrium lattice modulations

open access: yesNew Journal of Physics, 2013
An ultracold gas of interacting fermionic atoms in a three-dimensional optical lattice is considered, where the lattice potential strength is periodically modulated.

Characteristics of Meaning Processes and Phenomena in Team Interaction

open access: yesРоссийский психологический журнал, 2019
Introduction. Along with the socio-psychological characteristics of team interaction and management issues, innermost meaning aspects of team interaction merit special attention.

Review: Interactions of Active Colloids with Passive Tracers

open access: yesCondensed Matter, 2019
Collective phenomena existing universally in both biological systems and artificial active matter are increasingly attracting interest. The interactions can be grouped into active-active and active-passive ones, where the reports on the purely active ...

Cooperative phenomena in active matter systems with alternative interaction of neighbors [PDF]

open access: yesEPJ Web of Conferences
We investigate the impact of different nearest neighbor (NN) determination methods on flocking phase transitions in the Vicsek model. In addition to conventional methods (Cutoff, Voronoi, and k-NN), we implement a novel approach called 2D SANNex.

X-ray spectroscopic study of charge exchange phenomena in plasma-wall interaction

open access: yesEPJ Web of Conferences, 2013
Jets of energetic ions launched at laser-burnt-through foils represent an efficient tool for investigation of plasma interaction with solid surfaces (plasma-wall interaction, PWI) and for description of transient phenomena occurring close to the walls ...

Interaction phenomena of electrically coupled cells under local reactant starvation in automotive PEMFC stacks

open access: yesJPhys Energy, 2023
The local current density distribution of polymer electrolyte membrane fuel cells (PEMFCs) can be distorted by various error states. Differences in current density distributions (CDDs) of adjacent cells in a stack are equilibrized by in-plane currents ...
