Band structures of cylindrical AlN/GaN quantum dots with fully coupled piezoelectric models
(Proceedings of SPIE - The International Society for Optical Engineering, 2010-12-31)We study the coupled electro-mechanical effects in the band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as AlN/GaN quantum dots. Some effects in these systems are essentially nonlinear. ... -
Band structures of laterally coupled quantum dots, accounting for electromechanical effects
(Journal of Physics: Conference Series, 2010-12-31)In a series of recent papers we demonstrated that coupled electro-mechanical effects can lead to pronounced contributions in band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as quantum ... -
Bayesian inference for algorithm ranking analysis
(GECCO 2018 Companion - Proceedings of the 2018 Genetic and Evolutionary Computation Conference Companion 6 July 2018, Pages 324-325, 2018-08-30)The statistical assessment of the empirical comparison of algorithms is an essential step in heuristic optimization. Classically, researchers have relied on the use of statistical tests. However, recently, concerns about ... -
Bayesian nonparametric inference for the covariate-adjusted ROC curve
(2018-05-30)Accurate diagnosis of disease is of fundamental importance in clinical practice and medical research. Before a medical diagnostic test is routinely used in practice, its ability to distinguish between diseased and nondiseased ... -
BBIPED: BCAM-Baltogar Industrial Platform for Engineering Design
(18th International Conference on Circuits, Systems, Communications and Computers (CSCC 2014); Advances in Engineering Mechancis and Materials, Proc.the International Conference; on Industrial Engineering (INDE 2014)", 2014-12-31)Currently, commercial software for computational fluid dynamics offers a good set of features to deal with traditional designs. Within a competitive market industrial innovation is a key factor that must be faced by ... -
Best constants and Pohozaev identity for hardy-sobolev-type operators
(Communications in Contemporary Mathematics, 2013-12-31)This paper is threefold. Firstly, we reformulate the definition of the norm induced by the Hardy inequality (see [J. L. Vázquez and N. B. Zographopoulos, Functional aspects of the Hardy inequality. Appearance of a hidden ... -
A beta-binomial mixed-effects model approach for analysing longitudinal discrete and bounded outcomes
(Biometrical Journal, 2018-05)Patient-reported outcomes (PROs) are currently being increasingly used as primary outcome measures in observational and experimental studies since they inform clinicians and researchers about the health-status of patients ... -
Bilinear representation theorem
(Transactions of the American Mathematical Society, 2018-01-01)We represent a general bilinear Calderón--Zygmund operator as a sum of simple dyadic operators. The appearing dyadic operators also admit a simple proof of a sparse bound. In particular, the representation implies a so ... -
Blowup for a time-oscillating nonlinear heat equation
(Acta Mathematica Universitatis Comenianae, 2013-12-31)In this paper, we study a nonlinear heat equation with a periodic time oscillating term in factor of the nonlinearity. In particular, we give examples showing how the behavior of the solution can drastically change according ... -
Bootstrap-based procedures for inference in nonparametric receiver-operating characteristic curve regression analysis
(Statistical Methods in Medical Research, 2017)Prior to using a diagnostic test in a routine clinical setting, the rigorous evaluation of its diagnostic accuracy is essential. The receiver-operating characteristic curve is the measure of accuracy most widely used for ... -
Bootstrap-based procedures for inference in nonparametric ROC regression analysis
(2016-06-30)Before the use of a diagnostic test in a routine clinical setting, the rigorous evaluation of its diagnostic accuracy is an essential step. The receiver operating characteristic (ROC) curve is the measure of accuracy most ... -
Borderline Weighted Estimates for Commutators of Singular Integrals
(Israel Journal of Mathematics, 2016-07-01)In this paper we establish the following estimate \[ w\left(\left\{ x\in\mathbb{R}^{n}\,:\,\left|[b,T]f(x)\right| > \lambda\right\} \right)\leq \frac{c_{T}}{\varepsilon^{2}}\int_{\mathbb{R}^{n}}\Phi\left(\|b\|_{BMO}\f ... -
Boundary stabilization of numerical approximations of the 1-D variable coefficients wave equation: A numerical viscosity approach
(Lecture Notes in Computational Science and Engineering, 2014-12-31)In this paper, we consider the boundary stabilization problem associated to the 1- d wave equation with both variable density and diffusion coefficients and to its finite difference semi-discretizations. It is well-known ... -
Boundary unique continuation for stochastic parabolic equations
(Chinese Control Conference, CCC, 2012-12-31)This paper is devoted to the study the boundary unique continuation property for forward stochastic parabolic equations, i.e., determine the value of the solution by means of the observation on arbitrary open subset of the ... -
Breast cancer dormancy can be maintained by small numbers of micrometastases
(Cancer Research, 2010-12-31)Late relapse of breast cancer can occur more than 25 years after primary diagnosis. During the intervening years between initial treatment and relapse, occult cancers are maintained in an apparent state of dormancy that ... -
Brinicles as a case of inverse chemical gardens
(Langmuir, 2013-12-31)Brinicles are hollow tubes of ice from centimeters to meters in length that form under floating sea ice in the polar oceans when dense, cold brine drains downward from sea ice to seawater close to its freezing point. When ... -
A $C^0$ INTERIOR PENALTY DISCONTINUOUS GALERKIN METHOD FOR FOURTH ORDER TOTAL VARIATION FLOW
(Journal of Mathematical analysis and applications, 2017)We consider the numerical solution of a fourth order total variation flow problem representing surface relaxation below the roughening temperature. Based on a regularization and scaling of the nonlinear fourth order parabolic ... -
The Calderón problem with corrupted data
(Inverse Problems, 2017-01)We consider the inverse Calderón problem consisting of determining the conductivity inside a medium by electrical measurements on its surface. Ideally, these measurements determine the Dirichlet-to-Neumann map and, therefore, ... -
