Subleading shape-function effects and the extraction of jVubj
Keith S.M. Lee* California Institute of Technology, Pasadena, California 91125, USA (Received 26 February 2008; published 7 July 2008) We derive a class of formulae relating moments of B ! Xu‘ to B ! Xs in the shape-function region, where mX mb QCD. We also derive an analogous class of formulae involving the decay B ! Xs‘þ‘ . These results incorporate QCD=mb power corrections, but are independe...
متن کاملShape Functions from B̄ → X c l ν̄ l
We study inclusive semi-leptonic ¯ B → X c ℓ¯ ν ℓ decay using the power counting m c ∼ Λ QCD m b. Assuming this scaling for the charm-quark mass, the decay kinematics can be chosen to access the shape-function region even in b → c transitions. To apply effective field theory methods in this region we extend SCET to describe massive collinear quarks. Working at tree level and including O(Λ QCD /...
متن کاملInteractive function-based shape modelling
In this paper we address interactive shape modelling of geometric shapes defined by mathematical functions. We introduce mathematical operators that implement modifications of geometry and appearance of the shapes. Any of the operators involved in creating the shape can be edited, modified or removed at any time, thus allowing for a great flexibility of the modelling pipeline and opening prospe...
متن کاملEngineering cell shape and function.
An elastomeric stamp, containing defined features on the micrometer scale, was used to imprint gold surfaces with specific patterns of self-assembled monolayers of alkanethiols and, thereby, to create islands of defined shape and size that support extracellular matrix protein adsorption and cell attachment. Through this technique, it was possible to place cells in predetermined locations and ar...
متن کاملShape-changing L-sr1 Trust-region Methods
In this article, we propose a method for solving the trust-region subproblem when a limited-memory symmetric rank-one matrix is used in place of the true Hessian matrix. The method takes advantage of two shape-changing norms to decompose the trust-region subproblem into two separate problems, one of which has a closed-form solution and the other one is easy to solve. Sufficient conditions for g...
