Intracardiac metastasis of lung adenocarcinoma diagnosed by convex-probe EBUS
(2014)
Convex-probe endobronchial ultrasound (CP-EBUS) identified a vascularised 30 mm lesion, along the right pulmonary vein extending into the LA (figure 2). Needle aspiration was performed to the described mass and to the ...
Equivalence of Convex Problem Geometry and Computational Complexity in the Separation Oracle Model
(INFORMS, 2009)
Consider the supposedly simple problem of computing a point in a convex set that is conveyed by a separation oracle with no further information (e. g., no domain ball containing or intersecting the set, etc.). The authors' ...
Critical angles between two convex cones I. General theory
(Springer, 2016)
The concept of critical (or principal) angle between two linear subspaces has applications in statistics, numerical linear algebra, and other areas. Such concept has been abundantly studied in the literature, both from a ...
Integration of Nonconvex Epi-Pointed Functions in Locally Convex Spaces
(Hekdermann, 2016)
We extend the results of Correa, Garcia and Hantoute [6], dealing with the integration of nonconvex epi-pointed functions using the Fenchel subdifferential. In this line, we prove that the classical formula of Rockafellar ...

Convexity properties of the condition number
(Society for Industrial and Applied Mathematics, 2010-03)
We define in the space of n×m matrices of rank n, n ≤ m, the condition Riemannian structure as follows: For a given matrix A the tangent space at A is equipped with the Hermitian inner product obtained by multiplying the ...
