Compatible Lie brackets related to elliptic curve
, 2005 For the direct sum of several copies of sl_n, a family of Lie brackets compatible with the initial one is constructed. The structure constants of these brackets are expressed in terms of theta-functions associated with an elliptic curve. The structure of

A comparison of traditional and computer-aided bracket placement methods
The Angle Orthodontist, 2011 Abstract Objective: To test the hypothesis that there is no difference in the accuracy of bracket placement produced by OrthoCAD iQ indirect bonding (IDB) and that of an in-house fabricated IDB system by measuring the quality of intra-arch dental alignment at the end of simulated orthodontic treatment.

Pain and removal force associated with bracket debonding: a clinical study
Journal of Applied Oral Science, 2021 Objective: Pain is a problem during bracket removal, and more comfortable treatment is needed. This study examined the association of pain with the removal force required for ceramic brackets, compared with metal and plastic brackets, to determine which ...

Classification and Casimir Invariants of Lie-Poisson Brackets
, 1999 We classify Lie-Poisson brackets that are formed from Lie algebra extensions. The problem is relevant because many physical systems owe their Hamiltonian structure to such brackets. A classification involves reducing all brackets to a set of normal forms,
