Polygons as optimal shapes with convexity constraint

open access: yes, 2009
In this paper, we focus on the following general shape optimization problem: $$ \min\{J(\Om), \Om convex, \Om\in\mathcal S_{ad}\}, $$ where $\mathcal S_{ad}$ is a set of 2-dimensional admissible shapes and $J:\mathcal{S}_{ad}\to\R$ is a shape functional.

On the Second-Order Shape Derivative of the Kohn-Vogelius Objective Functional Using the Velocity Method

open access: yesInternational Journal of Differential Equations, 2015
The exterior Bernoulli free boundary problem was studied via shape optimization technique. The problem was reformulated into the minimization of the so-called Kohn-Vogelius objective functional, where two state variables involved satisfy two boundary ...

Local functional descriptors for surface comparison based binding prediction

open access: yesBMC Bioinformatics, 2012
Background Molecular recognition in proteins occurs due to appropriate arrangements of physical, chemical, and geometric properties of an atomic surface. Similar surface regions should create similar binding interfaces.

Immune microniches shape intestinal Treg function

open access: yesNature
AbstractThe intestinal immune system is highly adapted to maintaining tolerance to the commensal microbiota and self-antigens while defending against invading pathogens1,2. Recognizing how the diverse network of local cells establish homeostasis and maintains it in the complex immune environment of the gut is critical to understanding how tolerance can

MarNemaFunDiv: a first comprehensive dataset of functional traits for marine nematodes

open access: yesScientific Data
Here, we present the first comprehensive dataset of functional traits for marine nematodes (MarNemaFunDiv). In this study, we propose 16 functional traits (life strategy, body shape, trophic group, oesophageal bulb, cuticle complexity, adhesive ...

Structural transitions in a NiTi alloy: a multistage loading-unload cycle [PDF]

open access: yesFracture and Structural Integrity, 2011
NiTi shape memory alloys (SMAs) are increasingly used in many engineering and medical applications, because they combine special functional properties, such as shape memory effect and pseudo-elasticity, with good mechanical strength and biocompatibility.

Season, Microclimate and Shoreline Disturbance Interactively Shape Bird Functional Diversity

open access: yesEcology and Evolution
Understanding how ecological processes shape avian community structures remains fundamental to conservation in tropical coastal ecosystems, where birds serve crucial roles as seed dispersers, scavengers, and prey population regulators.
