Effect of passive leg raising on the cross-sectional area of the right internal jugular vein in patients with obesity: a randomised controlled trial protocol

Background Venous access in patients with obesity presents significant challenges. The success of central venous catheterisation largely depends on the cross-sectional area (CSA) of the internal jugular vein (IJV). While techniques like the Trendelen

We study in this article decay rates for Kelvin-Voigt damped wave equations under a geometric control condition. When the damping coefficient is sufficiently smooth ( C 1 C^1 vanishing nicely, see the following equation: | ∇ a | ⩽ C a 1 2 |\nabla

In this paper, a uniform and defective LaSrCoO4 was prepared by using amino acid derived surfactant (N-(2-hydroxylalkyl)- l -Phenylalanine). Owing to rich active groups of N-(2-hydroxylalkyl)- l -Phenylalanine, the resultant LaSrCoO4 showed enhanced

In this article, we study the observability (or equivalently, the controllability) of some subelliptic evolution equations depending on their step. This sheds light on the speed of propagation of these equations, notably in the ‘degenerated directi
