Nonlinear Decoupling in Discrete Time
IFAC Proceedings Volumes, 1989 Abstract In this paper we study static and dynamic single-input-single-output decoupling for the class of discrete-time nonlinear systems. We give necessary and sufficient conditions which ensure the static decoupling and the "state free "left invertibility of each input-output channel.

General Third-Order-Accuracy Formulas for Time Discretization Applied to Time-Varying Optimization
IEEE Access, 2020 Time discretization is an important part of time-varying problems solving that determines convergence, real-time performance and accuracy for solution models.

Symmetry, Integrability and Geometry: Methods and Applications, 2011 The original continuous-time "goldfish" dynamical system is characterized by two neat formulas, the first of which provides the $N$ Newtonian equations of motion of this dynamical system, while the second provides the solution of the corresponding initial-value problem.

Time‐scale transformations of discrete time processes [PDF]
Journal of Time Series Analysis, 2003 Abstract. This paper investigates the effects of temporal aggregation when the aggregation frequency is variable and possibly stochastic. The results that we report include, as a particular case, the well‐known results on fixed‐interval aggregation, such as when monthly data are aggregated into quarters.

On Discrete Time Wilson Systems [PDF]
Journal of Mathematics, 2020 In this paper, we define the discrete time Wilson frame (DTW frame) forl2ℤand discuss some properties of discrete time Wilson frames. Also, we give an interplay between DTW frames and discrete time Gabor frames. Furthermore, a necessary and a sufficient condition for the DTW frame in terms of Zak transform are given.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Electronic Journal of Differential Equations, 2020 Recently, a time discretization of simultaneous abstract evolution equations applied to parabolic-hyperbolic phase-field systems has been studied. This article focuses on a time discretization of an abstract problem that has application to linearized

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.
