Multi-Start Methods
(Springer, 2018-08-27)
[EN]Multi-start procedures were originally conceived as a way to exploit a local or neighborhood search procedure, by simply applying it from multiple random initial solutions. Modern multi-start methods usually incorporate ...
A Tunable Generator of Instances of Permutation-Based Combinatorial Optimization Problems
(2016-04)
[EN]In this paper, we propose a tunable generator of instances of permutation-based Combinatorial Optimization Problems. Our approach is based on a probabilistic model for permutations, called the Generalized Mallows model. ...
An Evaluation of Methods for Estimating the Number of Local Optima in Combinatorial Optimization Problems
(MIT Press, 2013-11-01)
[EN] The solution of many combinatorial optimization problems is carried out by metaheuristics, which generally make use of local search algorithms. These algorithms use some kind of neighborhood structure over the search ...
Wearable Slot Antenna at 2.45 GHz for Off-Body Radiation: Analysis of Efficiency,Frequency Shift, and Body Absorption
(Wiley, 2017-09-12)
The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown ...
On a Common Mistake in the Description of the Photoelectric Effect
(AIP, 2019-11-01)
The photoelectric effect is one of the key experiments taught during first- or second-year university and high school modern physics courses. It is usually the first experiment to introduce light quantization and the concept ...
(Re)translation and Reception of Neologisms in Science Fiction: A Methodological Proposal
(UCOPress, 2020-08-02)
This paper proposes a new methodology for studying neologismsin the translation and retranslation of the science fiction novel Altered Carbon (Richard Morgan,2001), its adaptation as a TV series by Netflix ...
Pronounced northward shift of the westerlies during MIS 17 leading to the strong 100-kyr ice age cycles
(Earth and Planetary Science Letters, 2019)
The MIS 17 interglacial, ~715 675 ka, marks the end of the Mid-Pleistocene Transition as intensified, long and asymmetrical 100-kyr ice age cycles became eminently established. Increasing arrival of moisture to the Northern ...
Pronounced northward shift of the westerlies during MIS 17 leading to the strong 100-kyr ice age cycles

The MIS 17 interglacial, ~715 675 ka, marks the end of the Mid-Pleistocene Transition as intensified, long and asymmetrical 100-kyr ice age cycles became eminently established. Increasing arrival of moisture to the Northern ...
Organocatalytic α-functionalization of carbonyl compounds: chemo-, regio- and stereoselectivity.
(2018-05-07)
The aim of this thesis has been the development of new synthetic procedures for the asymmetric formation of carbonyl componenets bearing a stereocenter at C¿. Covered topics include (i) the particular case of the use of ...
Isocyano(thio)acetates in Asymmetric Organocatalytic Reactions: Divergent Access to α-Quaternary Δ4- and Δ5-Dehydroprolines
(2018-12-19)
Las prolinas cuaternarias son aminoácidos estructuralmente únicos de granimportancia en química de péptidos, así como en el área de productos naturales ysustancias biológicamente activas. La estrategia más utilizada para ...
