Delay time modulation induced oscillating synchronization and intermittent anticipatory/lag and complete synchronizations in time-delay nonlinear dynamical systems [PDF]

open access: yes, 2007
Existence of a new type of oscillating synchronization that oscillates between three different types of synchronizations (anticipatory, complete and lag synchronizations) is identified in unidirectionally coupled nonlinear time-delay systems having two ...

Potential role of the interaction between equine estrogens, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) in the prevention of coronary heart and neurodegenerative diseases in postmenopausal women

open access: yesLipids in Health and Disease, 2003
Background An inverse relationship between the level of high-density lipoprotein (HDL) and coronary heart disease (CHD) has been reported. In contrast, oxidized HDL (oHDL) has been shown to induce neuronal death and may play an important role in the ...

Analysis of a generalized Fujikawa’s growth model

open access: yesMathematical Biosciences and Engineering, 2020
We analyze a generalized form of the Fujikawas growth model which involves an adaptation function that enhances the representation of the lag phase. This model is autonomous, and combines a power law term, a saturation term and an adaptation function ...

Finding indications of lag time, saturation and trading inflow in the emergence record of exotic agricultural insect pests in Japan

open access: yesApplied Entomology and Zoology, 2019
Agricultural imports are the primary pathway for the introduction of exotic insect pests. The invasion records of exotic insect pests are also influenced by the lag time before detection and saturation caused by the limited species pool of potential ...

The phase relation between sunspot numbers and soft X-ray flares

open access: yes, 2011
To better understand long-term flare activity, we present a statistical study on soft X-ray flares from May 1976 to May 2008. It is found that the smoothed monthly peak fluxes of C-class, M-class, and X-class flares have a very noticeable time lag of 13,

Time-optimal control of time-lag systems with time-lag controls

open access: yesJournal of Mathematical Analysis and Applications, 1975
AbstractThis paper considers the time-optimal control problem for a class of time-lag systems in which the time-lag is the control variable. It is shown that under certain conditions, the attainable set at any time t is convex, compact, and varies continuously with t. Using this result, a necessary condition for the time-optimal controls in the form of

One-Cell Doubling Evaluation by Living Arrays of Yeast, ODELAY!

open access: yesG3: Genes, Genomes, Genetics, 2017
Cell growth is a complex phenotype widely used in systems biology to gauge the impact of genetic and environmental perturbations. Due to the magnitude of genome-wide studies, resolution is often sacrificed in favor of throughput, creating a demand for ...
