Remote Sensing in Ecology and Conservation, EarlyView.Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Convexity and Subharmonic Functions
Irish Mathematical Society Bulletin, 1986 In diesem Tagungsbericht macht der Autor auf neueste Ergebnisse im Zusammenhang von Konvexität und subharmonischen Funktionen und über verallgemeinerte Mittelwerte aufmerksam. Ausführlich sind oder werden diese behandelt: vom Autor [J. Math. Anal. Appl. 108, 507-514 (1985; Zbl 0582.31005)], vom Autor und \textit{M. Klimek} [Bull. Lond. Math. Soc.

Journal of Anatomy, EarlyView.New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

WIREs Data Mining and Knowledge Discovery, Volume 16, Issue 3, September 2026.Seven‐stage AI‐powered voice biomarker pipeline for neurodegenerative disease diagnosis and clinical decision support. ABSTRACT Recent studies have shown that voice analysis provides a feasible, non‐invasive diagnostic alternative for the early detection of neurodegenerative diseases (NDs), such as Parkinson's disease (PD) and Amyotrophic Lateral ...

L^p-subharmonic functions in R^n
Electronic Journal of Differential Equations, 2016 We prove that if u is an $L^p$-subharmonic function defined outside a compact set in $\mathbb{R}^n$, it is bounded above near infinity, in particular, if the subharmonic function u is in $L^p(\mathbb{R}^n)$, $1\leq ...

Subharmonic functions and associated measures in ℝn
Open MathematicsFor subharmonic functions ss in Rn,n≥2,{{\mathbb{R}}}^{n},n\ge 2, there is an associated Radon measure μ\mu that is used to represent ss locally as an integral up to an additive harmonic function. We prove that the total measure μ(R2)\mu ({{\mathbb{R}}}^

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.Complex dynamics, often avoided in electromechanical design, can enhance soft robotics. We develop durable magnetic soft actuators operating in tunable dynamic regimes, enabling random number generation, stochastic computing, and time‐series prediction.

Subharmonic resonance and fixed-range asymptotic stability of the fractional-order SD oscillator
Advances in Mechanical EngineeringThe smooth and discontinuous (SD) oscillator is a typical system with strong nonlinear characteristics, and it is widely used in low-frequency vibration isolation and energy harvesting. A fractional damping model denoted by the Caputo model is introduced

Abstract and Applied Analysis, 2012 By introducing subdifferentiability of lower semicontinuous convex function φ(x(t),x(t−τ)) and its conjugate function, as well as critical point theory and operator equation theory, we obtain the existence of multiple subharmonic periodic solutions to ...
