On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion
International Journal for Numerical Methods in Fluids, EarlyView.Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

A Semi‐Implicit Numerical Method for Simultaneous Fluid‐Structure Interaction
International Journal for Numerical Methods in Fluids, EarlyView.A one‐dimensional shallow water model is coupled with a floating boat, which is assumed to be in hydrostatic equilibrium with the underlying water. Numerically, a semi‐implicit discretization of the shallow water equations also includes the Archimedes' floating conditions in such a fashion that the boat's vertical position and pitch slope are ...

International Journal of Finance &Economics, EarlyView.ABSTRACT This paper examines how Corporate Venture Capital (CVC), Independent Venture Capital (IVC) and Venture Capital Syndicate (VCS) promote innovation among startups. Drawing on a dataset of 4406 venture‐backed deals in North America, spanning 1998–2019, it explores how the configurations of investors and their contextual factors influence ...

Uncertain Short‐Run Restrictions and Statistically Identified Structural Vector Autoregressions
Journal of Applied Econometrics, EarlyView.ABSTRACT This study proposes a combination of a statistical identification approach with potentially invalid short‐run zero restrictions. The estimator shrinks towards imposed restrictions and stops shrinkage when the data provide evidence against a restriction.

Journal of Clinical Ultrasound, EarlyView.A moderate‐sized femoral neck osteophyte (white arrow) in US (A), anteroposterior CR (B), and MRI (C). Additional osteoarthritis‐related changes (arrowheads) are visible in CR and MR, but not in US. US and CR demonstrated similar moderate diagnostic capability to detect mild hip osteoarthritis and were associated with increased hip pain.

Defining stream riparian zones across multidimensional environmental gradients
Journal of Environmental Quality, EarlyView.Abstract Riparian zones are a critical terrestrial‐aquatic ecotone. They play important roles in ecosystems including (1) harboring biodiversity, (2) influencing light and carbon fluxes to aquatic food webs, (3) maintaining water quality and streamflow, (4) enhancing aquatic habitat, (5) influencing greenhouse gas production, and (6) sequestering ...
