The clustering of galaxies in the sdss-iii baryon oscillation spectroscopic survey: Baryon acoustic oscillations in the data release 9 spectroscopic galaxy sample [PDF]

, 2012
We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey (BOSS), which is part of the Sloan Digital Sky ...

Sensory feedback, error correction, and remapping in a multiple oscillator model of place cell activity

Frontiers in Computational Neuroscience, 2011
Mammals navigate by integrating self-motion signals (‘path integration’) and occasionally fixing on familiar environmental landmarks. The rat hippocampus is a model system of spatial representation in which place cells are thought to integrate both ...

Unified Smith predictor-based loop-shaping H(∞) damping controller for mitigating inter-area oscillations in power system

IET Cyber-Physical Systems, 2020
Low-frequency inter-area oscillation is one of the major problems to transfer the bulk power from one area to another area in an interconnected large power system.

Oscillation and non-oscillation criteria for second order linear non homogeneous functional-differential equations [PDF]

arXiv, 2022
The Riccati equation method is used to establish oscillation and non-oscillation criteria for second order linear nonhomogeneous functional-differential equations.We show that the obtained oscillation criterion is a generalization of J. S. W. Wong's oscillation criterion for second order linear nonhomogeneous ordinary differential equations.

Synchronization of oscillators coupled through an environment [PDF]

Physica D: Nonlinear Phenomena 237 (2008), 2933-2944, 2008
We study synchronization of oscillators that are indirectly coupled through their interaction with an environment. We give criteria for the stability or instability of a synchronized oscillation. Using these criteria we investigate synchronization of systems of oscillators which are weakly coupled, in the sense that the influence of the oscillators on ...

Time, the final frontier

Molecular Oncology, EarlyView.
This article advocates integrating temporal dynamics into cancer research. Rather than relying on static snapshots, researchers should increasingly consider adopting dynamic methods—such as live imaging, temporal omics, and liquid biopsies—to track how tumors evolve over time.

Effect of subcritical excitation of oscillations in stochastic systems with time delay. Part I. Regulation of gene expression [PDF]

Компьютерные исследования и моделирование, 2011
We study excitation of oscillations in the stochastic gene systems with time-delayed feedback loop during transcription. The oscillations arise due to interaction noise and time delay even when deterministic counterpart of the system exhibits stationary ...

Modeling Cell Energy Metabolism as Weighted Networks of Non-autonomous Oscillators

Frontiers in Physiology, 2021
Networks of oscillating processes are a common occurrence in living systems. This is as true as anywhere in the energy metabolism of individual cells. Exchanges of molecules and common regulation operate throughout the metabolic processes of glycolysis ...

Cerebral autoregulation in patients with acute lacunar infarction: a reliable predictor of outcome

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objective To further investigate the association between dynamic cerebral autoregulation (dCA) and the outcomes in patients with acute lacunar infarction. Methods Patients were prospectively and consecutively enrolled at The First Hospital of Jilin University between 2016 and 2023. dCA was monitored at 1–3 and 7–10 days after the stroke.

Locate the Source of Resonance-Involved Forced Oscillation in Power Systems Based on Mode Shape Analysis [PDF]

arXiv, 2020
This paper proposed a new method to locate the source of forced oscillation that involves resonance with natural oscillation modes. The new method is based on comparing the oscillation mode shape of the forced oscillation with that of the natural oscillation that the forced oscillation resonating with. The location that has the largest angle difference
