Deforming diamond

IMA Journal of Applied Mathematics, 2016
For materials science, diamond crystals are almost unrivaled for hardness and a range of other properties. Yet, when simply abstracting the carbon bonding structure as a geometric bar-and-joint periodic framework, it is far from rigid. We study the geometric deformations of this type of framework in arbitrary dimension d, with particular regard to the ...

Deformable classifiers

Quarterly of Applied Mathematics, 2019
Geometric variations of objects, which do not modify the object class, pose a major challenge for object recognition. These variations could be rigid as well as non-rigid transformations. In this paper, we design a framework for training deformable classifiers, where latent transformation variables are introduced, and a ...

Influence of screw density on thoracic kyphosis restoration in hypokyphotic adolescent idiopathic scoliosis

BMC Musculoskeletal Disorders, 2017
Background Previous studies have reported that rod composition and diameter, as well as the correction technique are key factors associated with thoracic kyphosis (TK) restoration. However, few study has analyzed the correlation between screw density and

'Windswept deformity'. [PDF]

Archives of Disease in Childhood, 1983
We describe 8 children with 'windswept deformity'--a valgus deformity of 1 knee in association with a varus deformity of the other. The disease is a physeal osteochondrosis and conservative treatment with serial corrective plaster casts is as effective as corrective osteotomies.
