Oscillations of First Order Delay Dynamic Equations
, 2006 Stavroulakis, Ioannis/0000-0002-4810-0540Consider the first order linear delay dynamic equation of the forms x(Delta)(t) + p(t)x(tau(t)) = 0. (E) New oscillation criteria are established which contain well-known criteria for delay differential and ...

Hydroelastic dynamic characteristics of a slender axis-symmetric body [PDF]
, 2010 The slender axis-symmetric submarine body moving in the vertical plane is the object of our investigation. A coupling model is developed where displacements of a solid body as a Euler beam (consisting of rigid motions and elastic deformations) and fluid ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
