Journal of Ultrasound in Medicine, EarlyView.Objectives To evaluate the value of the thickness of the frontal lobe (TFL) and foramen magnum‐to‐cranium distance (FCD) for predicting poor neurodevelopmental outcomes in fetuses with a small head circumference (HC). Methods This retrospective observational study included 39 fetuses with HC < −2 standard deviations (SD) and 592 prospectively collected

Boundary-layer equations in generalized curvilinear coordinates [PDF]
A set of higher-order boundary-layer equations is derived valid for three-dimensional compressible flows. The equations are written in a generalized curvilinear coordinate system, in which the surface coordinates are nonorthogonal; the third axis is ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Geometrically nonlinear static analysis of materially imperfect composite doubly curved shells is investigated via the generalised differential quadrature method. The effects of both shear and thickness deformation are considered through a thickness‐ and shear‐deformable third‐order theory formulated in curvilinear coordinates, while the ...

Back to the Mission. Revisiting Slack in Nonprofits and Introducing Tappable Slack
Nonprofit Management and Leadership, EarlyView.ABSTRACT This article contributes to and develops the previous literature on excess resources (“slack”) in nonprofit organizations through a conceptual analysis of the implications that the organizational distinctiveness of nonprofits carries for our understanding of slack in these organizations.

Dependence of average path length betatron motion in a storage ring
Physical Review Special Topics. Accelerators and Beams, 2005 The dependence of path length on betatron motion in a storage ring is analytically calculated from equations of motion using curvilinear coordinates. It is demonstrated that the change of average path length for one revolution is expressed by a sum of ...

Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary This study draws on the behavioral theory of the firm and a duality perspective to investigate the impact of founders' focus on academic goals on the financial performance of academic spin‐offs (ASOs)—a specific type of hybrid venture. We theorize that such relationship follows an inverse U‐shaped curve and is moderated by the

A formulation for the boundary-layer equations in general coordinates [PDF]
This is a working paper in which a formulation is given for solving the boundary-layer equations in general body-fitted curvilinear coordinates while retaining the original Cartesian dependent variables.
