Neural Nonparametric Stability Indicator for Self-Excited Dynamical Systems
IEEE AccessThis article introduces a novel methodology employing deep-learning neural networks to estimate Lyapunov functions in dynamic systems accurately. Unlike traditional parametric approaches, our method is model-free, enabling adaptability to various system ...

Novel stability results for traveling wavefronts in an age-structured reaction-diffusion equation
Mathematical Biosciences and Engineering, 2009 For a time-delayed reaction-diffusion equation of age-structuredsingle species population, the linear and nonlinear stability ofthe traveling wavefronts were proved by Gourley [4] andLi-Mei-Wong [8] respectively. The stability results,however, assume the

FEBS Letters, EarlyView.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

A nonlinear $L^2$-stability analysis for two-species population dynamics with dispersal
Mathematical Biosciences and Engineering, 2005 The nonlinear $L^2$-stability (instability) of the equilibrium statesof two-species population dynamics with dispersal is studied. The obtainedresults are based on (i) the rigorous reduction of the $L^2$-nonlinear stability tothe stability of the zero ...

Molecular Oncology, EarlyView.There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...

Two-dimensional matter-wave solitons and vortices in competing cubic-quintic nonlinear lattices
, 2017 The nonlinear lattice---a new and nonlinear class of periodic potentials---was recently introduced to generate various nonlinear localized modes. Several attempts failed to stabilize two-dimensional (2D) solitons against their intrinsic critical collapse
