Periodic problem for an impulsive system of the loaded hyperbolic equations
Electronic Journal of Differential Equations, 2018 We consider a periodic problem for a system of the loaded hyperbolic equations with impulse effects. By introducing additional functions, this problem is reduced to an equivalent problem consisting of a family of periodic boundary-value problems of

Symplectic Singularities and Solvable Hamiltonian Mappings
Demonstratio Mathematica, 2015 We study singularities of smooth mappings F̄ of ℝ2n into symplectic space (ℝ2n , ω̇) by their isotropic liftings to the corresponding symplectic tangent bundle (Tℝ2n,w). Using the notion of local solvability of lifting as a generalized Hamiltonian system,

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

A Stability Index for Local Effectivity Functions [PDF]
We study the structure of unstable local effectivity functions defined for n players and p alternatives. A stability index based on the notion of cycle is introduced.

Injective mappings and solvable vector fields
Anais da Academia Brasileira de Ciências, 2010 We establish a sufficient condition for injectivity in a class of mappings defined on open connected subsets of Rn , for arbitrary n. The result relates solvability of the appropriate vector fields with injectivity of the mapping and extends a result ...

Advanced Newton Methods for Geodynamical Models of Stokes Flow With Viscoplastic Rheologies
Geochemistry, Geophysics, Geosystems, 2020 Strain localization and resulting plasticity and failure play an important role in the evolution of the lithosphere. These phenomena are commonly modeled by Stokes flows with viscoplastic rheologies.
