Searching for behavioral homologies: Shared generative rules for expansion and narrowing down of the locomotor repertoire in Arthropods and Vertebrates [PDF]
We use immobility as an origin and reference for the measurement of locomotor behavior; speed, the direction of walking and the direction of facing as the three degrees of freedom shaping fly locomotor behavior, and cocaine as the parameter inducing a progressive transition in and out of immobility.

Automated 3D cephalometric landmark identification using computerized tomography [PDF]
Identification of 3D cephalometric landmarks that serve as proxy to the shape of human skull is the fundamental step in cephalometric analysis. Since manual landmarking from 3D computed tomography (CT) images is a cumbersome task even for the trained experts, automatic 3D landmark detection system is in a great need.

Variations of arthropod biodiversity due to human intervention and climatic variations study of a protected and a non-protected area in a tropical forest [PDF]
The diversity of the arthropod fauna from the pacific coast in southern Mexico was investigated in order to study and compare the biodiversity of two different regions. One is located within the Biosphere reserve "La encrucijada" and the second one on the edges of this reserve at a non-protected region.

Unified Heat Kernel Regression for Diffusion, Kernel Smoothing and Wavelets on Manifolds and Its Application to Mandible Growth Modeling in CT Images [PDF]
We present a novel kernel regression framework for smoothing scalar surface data using the Laplace-Beltrami eigenfunctions. Starting with the heat kernel constructed from the eigenfunctions, we formulate a new bivariate kernel regression framework as a weighted eigenfunction expansion with the heat kernel as the weights.

Towards Automatic Identification of Missing Tissues using a Geometric-Learning Correspondence Model [PDF]
Missing tissue presents a big challenge for dose mapping, e.g., in the reirradiation setting. We propose a pipeline to identify missing tissue on intra-patient structure meshes using a previously trained geometric-learning correspondence model. For our application, we relied on the prediction discrepancies between forward and backward correspondences ...
