Periodicity and stability for variable-time impulsive neural networks.
Li H, et al. Neural Netw 2017. PMID 28732232
Meanwhile, the fixed-time impulsive systems can be regarded as the comparison system of the variable-time impulsive neural networks. Furthermore, a series of sufficient criteria are derived to ensure the existence and global exponential stability of periodic solution of variable-time impulsive neural networks, and to illustrate the same stability properties between variable-time impulsive neural networks and the fixed-time ones. ...

From seconds to eons: Time scales, hierarchies, and processes in evo-devo.
Baedke J and Mc Manus SF. Stud Hist Philos Biol Biomed Sci 2018. PMID 30391127
This paper addresses the role of time scales in conceptualizing biological hierarchies. So far, the concept of hierarchies in philosophy of science has been dominated by the idea of composition and parthood, respectively. ...It distinguishes processes based on the different time scales (i.e. rates, frequencies, and rhythms) on which they occur. These time scale hierarchies often are connected with assumptions defended in process ontology. ...

A Seasonal Time-Series Model Based on Gene Expression Programming for Predicting Financial Distress.
Cheng CH, et al. Comput Intell Neurosci 2018. PMID 29765399 Free PMC article.
Financial statements are quarterly reports; hence, the financial crisis of companies is seasonal time-series data, and the attribute data affecting the financial distress of companies is nonlinear and nonstationary time-series data with fluctuations. Therefore, this study employed the nonlinear attribute selection method to build a nonlinear financial distress prediction model: that is, this paper proposed a novel seasonal time-series gene expression programming model for predicting the financial distress of companies. ...

Statistical Analysis of Categorical Time Series of Atmospheric Elementary Circulation Mechanisms - Dzerdzeevski Classification for the Northern Hemisphere.
Brenčič M. PLoS One 2016. PMID 27116375 Free PMC article.
Seasonality and the periodicity effect were investigated with moving dispersion filters and randomisation procedure on the ECM categories as well as with the time analyses of the ECM mode. The time series were determined as being non-stationary with strong time-dependent trends. During the investigated period, periodicity interchanges with periods when no seasonality is present. ...

Maxwell's demons everywhere: evolving design as the arrow of time.
Bejan A. Sci Rep 2014. PMID 24510201 Free PMC article.
Here I show that the arrow of time is painted much more visibly on another self-standing phenomenon: the occurrence and change (evolution in time) of flow organization throughout nature, animate and inanimate. This other time arrow has been present in science but not recognized as such since the birth of thermodynamics. It is Maxwell's demon. ...

C1-almost periodic solutions of BAM neural networks with time-varying delays on time scales.
Li Y, et al. ScientificWorldJournal 2015. PMID 25685847 Free PMC article.
On a new type of almost periodic time scales, a class of BAM neural networks is considered. By employing a fixed point theorem and differential inequality techniques, some sufficient conditions ensuring the existence and global exponential stability of C1-almost periodic solutions for this class of networks with time-varying delays are established. ...

Time and decision making in humans.
Klapproth F. Cogn Affect Behav Neurosci 2008 - Review. PMID 19033245
This article reviews the relationship between time and decision making in humans with respect to this evaluation process. Moreover, the role of psychological time, as compared with physical time, is accentuated. Five topics have been selected that illustrate how time and mental representations of time affect decision making. These are (1) the duration of options, (2) temporal decision making, (3) the time between having made a decision and experiencing the consequences of that decision, (4) the temporal perspective of decision makers, and (5) the duration of the decision process. ...

Time constants and electrotonic length of membrane cylinders and neurons.
Rall W. Biophys J 1969. PMID 5352228 Free PMC article.
In addition to the well known passive membrane time constant, tau(m) = R(m)C(m), observed in the decay of a uniform membrane potential, there exist many smaller time constants that govern rapid equalization of membrane potential over the length. ...Similar time constants are derived when a lumped soma is coupled to one or more cylinders representing one or more dendritic trees. ...

Internalization of seasonal time.
Prendergast BJ. Horm Behav 2005 - Review. PMID 16026787
Orientation of physiology and behavior in time is a major adaptation common to many organisms and represents a significant challenge. ...Recent work that has explored formal and physiological properties of this photorefractoriness interval timer has identified sex differences, neural substrates, and changes in hypothalamic gene expression that may participate in the measurement of seasonal time....

Global exponential stability of positive periodic solution of the n-species impulsive Gilpin-Ayala competition model with discrete and distributed time delays.
Zhao K. J Biol Dyn 2018. PMID 29737924
In this paper, we study the n-species impulsive Gilpin-Ayala competition model with discrete and distributed time delays. The existence of positive periodic solution is proved by employing the fixed point theorem on cones. ...
