Beyond Basins of Attraction: Quantifying Robustness of Natural Dynamics
, 2019 Properly designing a system to exhibit favorable natural dynamics can greatly simplify designing or learning the control policy. However, it is still unclear what constitutes favorable natural dynamics and how to quantify its effect.

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

MODELING HETEROGENEOUS ENVIRONMENT AND MOBILE OBJECTS SUPERVISION IN MONITORING PROBLEMS
Informatika, 2016 A variant of monitoring problem formalization on the basis of the decision theory is considered. The models of heterogeneous environment and mobile heterogeneous object are offered as a structuralinformative basis for solving typical monitoring tasks ...

Inferring reaction network structure from single-cell, multiplex data, using toric systems theory.
PLoS Computational Biology, 2019 The goal of many single-cell studies on eukaryotic cells is to gain insight into the biochemical reactions that control cell fate and state. In this paper we introduce the concept of Effective Stoichiometric Spaces (ESS) to guide the reconstruction of ...

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Efficient Wheel-Rail Stick-Slip Numerical Modeling for Railway Traction Vehicles
Applied SciencesMotor railway vehicles necessitate enhanced control of wheel-rail contact mechanics to ensure optimal adhesion. During train running, driving wheelsets exhibit torsional vibrations that compromise adhesion and potentially lead to axle damage ...

Added Value-based Approach to Analyze Electronic Commerce and Mobile Commerce Business Models [PDF]
, 2003 In this contribution we propose to apply the theory of informational added values (IAV) on electronic commerce (EC) and mobile commerce (MC). We state that for the success of electronic and mobile offers it is not sufficient to merely make a conventional

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
