The Nash Problem from a Geometric and Topological Perspective
(20180417)We survey the proof of the Nash conjecture for surfaces and show how geometric and topological ideas developed in previous articles by the au thors influenced it. Later we summarize the main ideas in the higher dimen ... 
Natureinspired approaches for distance metric learning in multivariate time series classification
(IEEE Congress on Evolutionary Computation, 2017)The applicability of time series data mining in many different fields has motivated the scientific community to focus on the development of new methods towards improving the performance of the classifiers over this particular ... 
Natureinspired approaches for distance metric learning in multivariate time series classification
(IEEE Congress on Evolutionary Computation (CEC), 201707)The applicability of time series data mining in many different fields has motivated the scientific community to focus on the development of new methods towards improving the performance of the classifiers over this particular ... 
Natureinspired heuristics for the multiplevehicle selective pickup and delivery problem under maximum profit and incentive fairness criteria
(IEEE Congress on Evolutionary Computation, 2017)This work focuses on widescale freight transportation logistics motivated by the sharp increase of online shopping stores and the upsurge of Internet as the most frequently utilized selling channel during the last decade. ... 
Nearlyoptimal scheduling of users with Markovian timevarying transmission rates
(Performance Evaluation, 20160101)We address the problem of developing a wellperforming and implementable scheduler of users with wireless connections to the central controller, which arise in areas such as mobile data networks, heterogeneous networks, ... 
Necking in 2D incompressible polyconvex materials: theoretical framework and numerical simulations
(Quarterly Journal of Mechanics and Applied Mathematics, 20170615)We show examples of 2D incompressible isotropic homogeneous hyperelastic materials with a polyconvex storedenergy function that present necking. The construction of the storedenergy function of amaterial satisfying all ... 
Nematic elastomers: Gammalimits for large bodies and small particles
(SIAM Journal on Mathematical Analysis, 20111231)We compute the largebody and the smallparticle Gammalimit of a family of energies for nematic elastomers. We work under the assumption of small deformations (linearized kinematics) and consider both compressible and ... 
A new approach to categorize continuous variables in prediction models: Proposal and validation
(Statistical Methods in Medical Research, 201712)When developing prediction models for application in clinical practice, health practitioners usually categorise clinical variables that are continuous in nature. Although categorisation is not regarded as advisable from ... 
New bounds for bilinear CalderónZygmund operators and applications
(Revista Matemática Iberoamericana, 20161125)In this work we extend Lacey’s domination theorem to prove the pointwise control of bilinear Calderón–Zygmund operators with Dini–continuous kernel by sparse operators. The precise bounds are carefully tracked following ... 
New Simplified Algorithm for the Multiple Rotating Frame Approach in Computational Fluid Dynamics
(Journal of Fluids Engineering, 20170602)This paper deals with rotating effects simulation of steady flows in turbomachinery. To take into account the rotating nature of the flow, the frozen rotor approach is one of the widely used approaches. This technique, ... 
New Theory of Flight
(Journal of Mathematical Fluid Mechanics, 20160101)We present a new mathematical theory explaining the fluid mechanics of subsonic flight, which is fundamentally different from the existing boundary layercirculation theory by Prandtl–Kutta–Zhukovsky formed 100 year ago. ... 
Némethi’s division algorithm for zetafunctions of plumbed 3manifolds
(Bulletin of the London Mathematical Society, 20180827)A polynomial counterpart of the SeibergWitten invariant associated with a negative definite plumbing 3manifold has been proposed by earlier work of the authors. It is provided by a special decomposition of the zetafunction ... 
No Time at the End of the Tunnel
(Communications Physics – Nature, 20180821)Modern attosecond experiments seek to provide an insight into a long standing question: “how much time does a tunnelling particle spend in the barrier?” Traditionally, quantum theory relates this duration to the delay ... 
Nonconforming curved finite element schemes for timedependent elasticacoustic coupled problems
(Journal of Computational Physics, 20160101)Highorder numerical methods for solving timedependent acousticelastic coupled problems are introduced. These methods, based on Finite Element techniques, allow for a flexible coupling between the fluid and the solid ... 
Noncooperative Equilibria of Fermi Systems With Long Range Interactions
(Memoirs of the AMS, 201307)We define a Banach space $\mathcal{M}_{1}$ of models for fermions or quantum spins in the lattice with long range interactions and explicit the structure of (generalized) equilibrium states for any $\mathfrak{m}\in ... 
NonMarkovian models of the growth of a polymer chain
(Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 20151231)Using simple exactly solvable models, we show that eventdependent time delays may lead to significant nonPoisson effects in the statistics of polymer chain growth. The results are confirmed by stochastic simulation of ... 
Nonnormal affine monoids, modules and Poincaré series of plumbed 3manifolds
(Acta Mathematica Hungarica, 20170518)We construct a nonnormal affine monoid together with its modules associated with a negative definite plumbed 3manifold M. In terms of their structure, we describe the $H_1(M,\mathbb{Z})$equivariant parts of the topological ... 
Nonreflecting boundary condition on ellipsoidal boundary
(Numerical Analysis and Applications, 20121231)The modeling of wave propagation problems using finite element methods usually requires the truncation of the computation domain around the scatterer of interest. Absorbing boundary conditions are classically considered ...
