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

p-Mechanics and Field Theory [PDF]
, 2004 The orbit method of Kirillov is used to derive the p-mechanical brackets [math-ph/0007030, quant-ph/0212101]. They generate the quantum (Moyal) and classic (Poisson) brackets on respective orbits corresponding to representations of the Heisenberg group ...

Étude comparée du fonctionnement des parenthèses et des tirets
Discours, 2011 This study investigates the functional equivalence of brackets and dashes. Both signs seem to mark “the operation of typographic uncoupling” (Pétillon-Boucheron, 2003). Our corpus study clearly shows, however, that their uses differ.

Quadratic Poisson brackets compatible with an algebra structure
, 1994 Quadratic Poisson brackets on a vector space equipped with a bilinear multiplication are studied. A notion of a bracket compatible with the multiplication is introduced and an effective criterion of such compatibility is given. Among compatible brackets,

Journal of Pharmacy and Bioallied SciencesBackground: The aim of this study was to evaluate the effect of separately curing the unfilled resin for increased bond strength of the orthodontic brackets as the literature shows both studies that support and contradict this aspect.

European Journal of Health Research, 2021 La instrumentación de las superficies radiculares en pacientes portadores de brackets es compleja e inefectiva al 100%, además no es agradable para el paciente, lo que en la mayoría de los casos hace que el paciente no acuda con la periodicidad necesaria

The Jacobi identity for Dirac-like brackets [PDF]
, 2001 For redundant second-class constraints the Dirac brackets cannot be defined and new brackets must be introduced. We prove here that the Jacobi identity for the new brackets must hold on the surface of the second-class constraints.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

Compatibility, multi-brackets and integrability of systems of PDEs [PDF]
, 2008 We establish an efficient compatibility criterion for a system of generalized complete intersection type in terms of certain multi-brackets of differential operators.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden.
