Unilateral Laplace Transforms on Time Scales

Mathematics, 2022
We review the direct and inverse Laplace transforms on non-uniform time scales. We introduce full backward-compatible unilateral Laplace transforms and studied their properties. We also present the corresponding inverse integrals and some examples.

Canonical time-frequency, time-scale, and frequency-scale representations of time-varying channels [PDF]

Communications in Information and Systems, 2005
Mobile communication channels are often modeled as linear time-varying filters or, equivalently, as time-frequency integral operators with finite support in time and frequency. Such a characterization inherently assumes the signals are narrowband and may not be appropriate for wideband signals.

A class of retarded Volterra-Fredholm type integral inequalities on time scales and their applications

Journal of Inequalities and Applications, 2017
In this paper, we study some new retarded Volterra-Fredholm type integral inequalities on time scales, which provide explicit bounds on unknown functions.

N-Dimensional Lattice Integrable Systems and Their bi-Hamiltonian Structure on the Time Scale Using the R-Matrix Approach

Axioms
A time scale is a special measure chain that can unify continuous and discrete spaces, enabling the construction of integrable equations. In this paper, with the Lax operator generated by the displacement operator, N-dimensional lattice integrable ...

Almost Periodic Time Scales and Almost Periodic Functions on Time Scales [PDF]

Journal of Applied Mathematics, 2015
We propose some new concepts of almost periodic time scales and almost periodic functions on time scales and give some basic properties of these new types of almost periodic time scales and almost periodic functions on time scales. We also give some comments on a recent paper by Wang and Agarwal (2014) concerning a new almost periodic time scale.

Understanding, communicating, and imagining urban biodiversity in German and Italian cities

npj Climate Action
Urban biodiversity has recently emerged as a key focus in urban planning discourse and is the cornerstone of the EU biodiversity strategy for 2030. This strategy proposes ambitious urban greening plans for cities with over 20,000 inhabitants to address ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
