Dose point kernel calculation and modelling with nuclear medicine dosimetry purposes
(2014)
Monoclonal labeled antibodies are commonly used for radioimmunotherapy purposes in nuclear medicine. The procedure is based on the deposition of specific radiactivity concentrations on tumoral regions with the aim of ...
Some totally geodesic submanifolds of the nonlinear Grassmannian of a compact symmetric space
(2014)
Let M and N be two connected smooth manifolds, where M is compact and oriented and N is Riemannian. Let E be the Fréchet manifold of all embeddings of M in N, endowed with the canonical weak Riemannian metric. Let ∼ be the ...
Dosimetry optimization system and integrated software (DOSIS) : a comparison against Fluka code results over a standard phantom
(2014)
Actually, dual-imaging facilities allow obtainance of both mass and activity patient-specific distributions perfectly correlated, which are important to improve dose distributions estimations and radioimmunotherapy treatment ...
Experimental determination of <10 10>/ Ψ tilt grain boundary energies in ice
(2014)
Ice grain boundary energies γgb relative to the free surface energy γs were determined by studying the topographic details revealed by plastic replicas of the ice grain boundary groove-free surface with a Laser Confocal ...
Strictly positive solutions for one dimensional nonlinear elliptic problems
(2014)
We study the existence and nonexistence of strictly positive solutions for the elliptic problems -- in a bounded open interval, with zero boundary conditions, where -- is a strongly uniformly elliptic differential operator, ...
Weighted inequalities for some integral operators with rough kernels
(2014)
In this paper we study integral operators with kernels K(x, y) = k1(x − A1y)...km(x − Amy), ki(x) = Ωi(x)
|x|n/qi where Ωi : Rn → R are homogeneous functions of degree zero, satisfying a size and a Dini condition, Ai are ...
Implementation of several mathematical algorithms to breast tissue density classification
(2014)
The accuracy of mammographic abnormality detection methods is strongly dependent on breast tissue characteristics, where a dense breast tissue can hide lesions causing cancer to be detected at later stages. In addition, ...
Mixing Bandt-Pompe and Lempel-Ziv approaches : another way to analyze the complexity of continuous-state sequences
(2014)
In this paper, we propose to mix the approach underlying Bandt-Pompe permutation entropy
with Lempel-Ziv complexity, to design what we call Lempel-Ziv permutation complexity. The principle
consists of two steps: (i) ...
Multisolitons with vector mesons on the two-sphere
(2014)
Recent studies have suggested a strong connection between the static solutions of the 3D Skyrme model and those corresponding to its low-dimensional analog (baby-Skyrme model) on a two-sphere. We have found almost identical ...
Spherical functions of fundamental K-types associated with the n-dimensional sphere
(2014)
In this paper, we describe the irreducible spherical functions of fundamental K-types associated with the pair (G, K) = (SO(n + 1), SO(n)) in terms of matrix hypergeometric functions. The output of this description is that ...
