This paper describes an automatic algorithm to restore the shape of three-dimensional (3D) left ventricle (LV) models created from magnetic resonance imaging (MRI) data using a geometry-driven optimization approach. Our basic premise is to restore the LV shape such that the LV epicardial surface is smooth after the restoration. A geometrical measure known as the Minimum Principle Curvature (κ2)...

Liquid crystal elastomers can vary their shape freely with no extra mechanical energy like liquids when deformed in the plane.

We design the micro-architecture of thin elastic panels to control their macroscopic behavior, accounting simultaneously for in-plane stiffness, out-of-plane stiffness and extension–bending coupling effects. Our topology optimization method combines inverse homogenization, Hadamard shape derivative a level set in diffuse interface context systematically capture within unit cell optimal micro-ar...

This work generalizes a shape recovery method for specular surJaces. We have used linear lights that generate planes of ray to highlight a rotating object so that its specular su$aces m computed from continuous images. By setting lights properly, shape at each rotation plane can be measured and a 30 graphics model can be subsequently reconstructed. In this paper, we extend our lights to circula...

objectives to compare an out-of-plane interscalene catheter technique to the in-plane technique in a randomized clinical trial. patients and methods eighty-four patients undergoing open shoulder surgery were randomized to either the in-plane or out-of-plane ultrasound-guided continuous interscalene technique. the primary outcome was vas pain rating at 24 hours. secondary outcomes included pain ...

Microfluidic technology allows to realize devices in which cells can be imaged in their three-dimensional shape. However, there are still some limitations in the method, due to the fact that cells follow a straight path while they are flowing in a channel. This can result in a loss in information, since only one side of the cell will be visible. Our work has started from the consideration that ...

Résumé. Cylindric plane partitions may be thought of as a natural generalization of reverse plane partitions. A generating series for the enumeration of cylindric plane partitions was recently given by Borodin. As in the reverse plane partition case, the right hand side of this identity admits a simple factorization form in terms of the “hook lengths” of the individual boxes in the underlying s...
