RESUMEN
The knowledge of the anatomical shape of both gross and microscopic structures is the key to understanding the effects of disease processes on cellular structure. Geometric morphometric methods, such as Procrustes superimposition, and Spherical Harmonics (SPHARM), have been used to capture the biological shape variation and group differences in morphology. Previous SPHARM-MAT techniques use the CALD algorithm to parameterize the mesh surface. It starts from initial mapping and performs local and global smoothing methods alternately to control the area and length distortions simultaneously. However, this parameterization may not be sufficient in complex morphological cases. To bridge this gap, we propose SPHARM-OT, an enhanced SPHARM surface modeling method using optimal transport (OT) for spherical parameterization. First, the genus 0 3D objects are conformally mapped onto a sphere. Then the optimal transport theory via spherical power diagram is introduced to minimize the area distortion. This new algorithm can effectively reduce the area distortion and lead to a better reconstruction result. We demonstrate the effectiveness of the method by applying it to the human sphenoidal paranasal sinuses.
RESUMEN
Community-engaged scholarship (CES)-research, teaching, programmatic and other scholarly activities conducted through partnerships between academic and community partners-may result in innovative applied products such as manuals, policy briefs, curricula, videos, toolkits, and websites. Without accepted mechanisms for peer-reviewed publication and dissemination, these products often do not "count" toward faculty promotion and tenure (P&T) and have limited opportunities for broad impact. This paper reports on CES4Health.info, a unique online tool for peer-reviewed publication and dissemination of products of CES in forms other than journal articles. In its first year, CES4Health.info has published 24 products and documented the satisfaction of users, authors, and reviewers.
