Ring Strain‐Promoted Activation of Pyridines by a Saturated BSi2 Cycle

Angewandte Chemie International Edition, EarlyView.
We report a highly strained boratadisilirane with the elusive anionic BSi2 ring motif. Cleavage of the Si─Si bond during reactions with pyridine derivatives activates them in three different ways: 1) for pyridine itself selective ortho‐CH activation and concomitant hydrogen transfer to a second pyridine molecule occurs, 2) with dimethylaminopyridine ...

System of degenerate parabolic p-Laplacian

Open Mathematics
In this article, we study the mathematical properties of the solution u=(u1,…,uk){\bf{u}}=({u}^{1},\ldots ,{u}^{k}) to the degenerate parabolic system ut=∇⋅(∣∇u∣p−2∇u),(p>2).{{\bf{u}}}_{t}=\nabla \hspace{0.25em}\cdot \hspace{0.25em}({| \nabla {\bf{u}}| }^

Population pharmacokinetic modelling revealed large variability in oromucosal absorption of Δ9‐tetrahydrocannabinol in older patients with poor appetite

British Journal of Clinical Pharmacology, EarlyView.
Aim Cannabis‐based medicines are gaining interest and being explored for new therapeutic indications, many of which commonly affect older medical patients. As most previous studies of the population pharmacokinetics of cannabinoids have been performed in healthy adults, this study aimed to investigate the population pharmacokinetics of Δ9 ...

Nodal properties for p-Laplacian systems

Electronic Journal of Differential Equations, 2017
We consider a system of differential equations involving the p-Laplacian. We prove the existence of oscillatory solutions with prescribed numbers of zeros, and show that the solutions satisfy the Dirichlet boundary conditions when the large parameters

Origin of the \(p\)-Laplacian and A. Missbach

Electronic Journal of Differential Equations, 2018
Summary: We describe the historical process of derivation of the \(p\)-Laplace operator from a nonlinear Darcy law and the continuity equation. The story begins with nonlinear flows in channels and ditches. As the nonlinear Darcy law we use the power law discovered by \textit{O.

Eigenvalues and the One-Dimensional p-Laplacian

Journal of Mathematical Analysis and Applications, 2002
The authors are concerned with determining values of \(\lambda\), for which there exist positive solutions to the boundary value problem \[ (\phi_p(u'))'+ \lambda F(t,u)= 0\quad\text{in }(0,1),\quad u(0)= u(1)= 0,\tag{P} \] with \(\phi_p(s)=|s|^{p-2}s\) and \(p> 1\).
