We present a new stability analysis for the second barycentric formula, showing that this formula is backward stable when the relevant Lebesgue constant is small.

This paper presents a novel structure based on liquid crystal (LC) technology to achieve high figure of merit $(FOM)$ phase shifter that works at sub-6 notation="LaTeX">$GHz$ frequencies. The phase-shifting mechanism is enabled through the constant variation in main microstrip line, which loaded p...

Highly aerobically trained individuals are unable to achieve maximal oxygen uptake ([Formula: see text]) during exhaustive running lasting ~2 min, instead [Formula: see text] plateaus below [Formula: see text] after ~1 min. Hypoxia offers the opportunity to study the ([Formula: see text]) response to an exhaustive run relative to a hypoxia induced reduction in [Formula: see text]. The aim of th...

This paper presents a variation of constants formula for the system of functional parabolic partial differential equations ∂u(t, x) ∂t = D∆u+ Lut + f(t, x), t > 0, u ∈ R ∂u(t, x) ∂η = 0, t > 0, x ∈ ∂Ω u(0, x) = φ(x) u(s, x) = φ(s, x), s ∈ [−τ, 0), x ∈ Ω . Here Ω is a bounded domain in Rn, the n × n matrix D is block diagonal with semi-simple eigenvalues having non negative real part, the operat...
