On Lyapunov inequality in stability theory for Hill's equation on time scales

Journal of Inequalities and Applications, 2000
In this paper we obtain sufficient conditions for instability and stability to hold for second order linear -differential equations on time scales with periodic coefficients.

Fractal–fractional model for analysis of tuberculosis infection using Ethiopia incidence data

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract In this study, a fractional‐order SEIuITR $SE{I}_{u}ITR$ model was proposed to examine the transmission of tuberculosis (TB) in the community. The proposed model was rigorously examined for well‐posedness. The basic reproduction number was also derived, and the disease‐free equilibrium was obtained.

Tracing Three Decades of Low Earth Orbit Satellite Communication Development: A Bibliometric and Main Path Analysis of Network Architectures, Protocol Evolution, and Emerging Intelligent Services

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 573-593, September/October 2026.
ABSTRACT Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G ...

Greenland's Topography Triggers Cyclogenesis: Synergy Between Lee Cyclogenesis and Jet Streak

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Arctic cyclones play a crucial role in shaping Arctic weather patterns and influencing sea ice concentrations. During the Multidisciplinary Drifting Observatory for the Study of Arctic Climate expedition in April 2020, an Arctic cyclone was observed at the leeside of Greenland, prompting our hypothesis that lee cyclogenesis contributed ...

Autonomy, forward non-Zenoness and quadratic stability of bimodal higher-order piecewise linear systems

We consider bimodal higher-order piecewise linear systems, i.e. the sets of solutions of two higher-order linear differential equations, coupled with inequality constraints involving a polynomial differential operator acting on the trajectories of the ...
