Differentiation of correlated fluctuations in site energy on excitation energy transfer in photosynthetic light-harvesting complexes

Results in Physics, 2022
One of the promising approaches to revealing the photosynthetic efficiency of close to one unit is to investigate the quantum regime of excitation energy transfer (EET).

fMRI fluctuations within the language network are correlated with severity of hallucinatory symptoms in schizophrenia

Schizophrenia, 2023
Although schizophrenia (SZ) represents a complex multiform psychiatric disorder, one of its most striking symptoms are auditory verbal hallucinations (AVH). While the neurophysiological origin of this pervasive symptom has been extensively studied, there

Fluctuations and correlations in STAR [PDF]

The European Physical Journal A, 2007
The study of correlations and fluctuations can provide evidence for the production of the quark-gluon plasma (QGP) in relativistic heavy ion collisions. Various theories predict that the production of a QGP phase in relativistic heavy ion collisions could produce significant event-by-event correlations and fluctuations in, transverse momentum ...

CORRELATIONS AND FLUCTUATIONS AT RHIC [PDF]

Multiparticle Dynamics, 2002
Particle correlations and fluctuations measured by RHIC experiments at $\sqrt{s_{NN}}$=130 GeV were discussed. The source size parameters were similar to those measured at the CERN-SPS, and no long duration time of particle emission were observed. It was pointed out that the dependences of longitudinal and transverse radius parameters on the pair ...

Cerebellar Purkinje Cells Generate Highly Correlated Spontaneous Slow-Rate Fluctuations

Frontiers in Neural Circuits, 2017
Cerebellar Purkinje cells (PC) fire action potentials at high, sustained rates. Changes in spike rate that last a few tens of milliseconds encode sensory and behavioral events.

Influence of environment induced correlated fluctuations in electronic coupling on coherent excitation energy transfer dynamics in model photosynthetic systems [PDF]

, 2012
Two-dimensional photon-echo experiments indicate that excitation energy transfer between chromophores near the reaction center of the photosynthetic purple bacterium Rhodobacter sphaeroides occurs coherently with decoherence times of hundreds of ...

Memory Corrections to Markovian Langevin Dynamics

Entropy
Analysis of non-Markovian systems and memory-induced phenomena poses an everlasting challenge in the realm of physics. As a paradigmatic example, we consider a classical Brownian particle of mass M subjected to an external force and exposed to correlated

Decisions on Dual-Channel Supply Chains under Market Fluctuations and Dual-Risk Aversion

Discrete Dynamics in Nature and Society, 2020
Considering market fluctuations and risk aversion, this paper analyzes the decisions of a dual-channel supply chain consisting of one manufacturer and one retailer and compares the differences in the centralized structure, manufacturer-dominated ...

Electric charge fluctuations in central Pb+Pb collisions at 20, 30, 40, 80 and 158 AGeV [PDF]

, 2004
Results are presented on event-by-event electric charge fluctuations in central Pb+Pb collisions at 20, 30, 40, 80 and 158 AGeV. The observed fluctuations are close to those expected for a gas of pions correlated by global charge conservation only. These

Fluctuations in Availability of Arthropods Correlated with Microchiropteran and Avian Predator Activities

Koedoe: African Protected Area Conservation and Science, 1988
Aerial arthropods were sampled by driving a standard transect along the riparian forest of the Luvuvhu River, South Africa, to assess hourly and seasonal variations in available biomass.
