Intraoperative Neurophysiological Monitoring in Spine Deformity Surgery

, 2023
Although the incidence of neurologic injury in deformity surgery is low, the repercussions are devastating; therefore, every measure available should be adopted to minimize that risk.

q-Deformed and c-Deformed Harmonic Oscillators [PDF]

Progress of Theoretical Physics, 2003
Summary: Hamilton functions of classical deformed oscillators (\(c\)-deformed oscillators) are derived from Hamiltonians of \(q\)-deformed oscillators of the Macfarlane and Dubna types. A new scale parameter, \(l_q\), with the dimension of length, is introduced to relate a dimensionless parameter characterizing the deformation with the natural length ...

Adult Spinal Deformity Surgeons Are Unable to Accurately Predict Postoperative Spinal Alignment Using Clinical Judgment Alone

, 2023
Object Adult spinal deformity (ASD) surgery seeks to reduce disability and improve quality of life through restoration of spinal alignment. In particular, correction of sagittal malalignment is correlated with patient outcome.

Assessment of the axial plane deformity in subjects with adolescent idiopathic scoliosis and its relationship to the frontal and sagittal planes [PDF]

, 2021
Purpose Investigate the axial plane deformity in the scoliotic segment and its relationship to the deformity in the frontal and sagittal planes. Methods Two hundred subjects with AIS (Cobb ≥ 20°) underwent low dose biplanar X-rays with 3D reconstruction ...

Classifying deformable and non-deformable video objects [PDF]

7th International Conference on Imaging for Crime Detection and Prevention (ICDP 2016), 2016
This paper presents a fully automated approach to classifying deformable and non-deformable moving objects in a video surveillance scene. We estimate an object's motion using Marzat optical-flow algorithm. We filter the motion vectors and attempt to find the transformation that represents the correct mapping between the two positions.

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 ...
