Research in economics in Spain: rankings of institutions and authors
No full textIn this paper we analyse the research in Economics in Spain during the 1990s considering the contributions of both Spanish and foreign economist who have worked in Spain during that period. To do so, we use different bibliometric indicators in order to elaborate rankings for both institutions and researchers. These rankings can be useful for several potentials users such as: a) Evaluation Agencies and Funding Bodies to help them in grant-allocation decisions; b) Graduate students who whish to choose the right institution to complete their postgraduate education, and c) Young Ph Ds who have entered the academic job market and need information about the research perfomance of different institutions

On-load Tap Changer Diagnosis on High-Voltage Power Transformers using Dynamic Resistance Measurements
No full textHigh-voltage transformers have tap changers to regulate the voltage in the high-voltage network when the load changes. Those tap changers are subject to different degradation mechanisms and need regular maintenance. Various defects, like contact degradation, often remain undetected and the probability of maintenance errors cannot be neglected. Preventive diagnosis of dynamic resistance can be used to determine the contact condition and to check the basic function of the tap changer. This can guarantee that the high-voltage transformer can be put back into operation safely after maintenance. In addition, the information obtained can be used for condition-based maintenance. The research of Jur Erbrink elaborates on the condition assessment of tap changers using dynamic resistance measurements. He describes in his thesis the different ways in which the measurements can be performed and how this influences the measurement results. In particular it was emphasized that the dynamic resistance measurements at a lower the test current are more sensitive for long term aging effects. It is also investigated which defects can be detected and how the results can be interpreted.High Voltage Technology and ManagementElectrical Engineering, Mathematics and Computer Scienc
Hybrid quantum-classical optimization with cardinality constraints and applications to finance
No full text26 pags., 12 figs.In this work we develop tools to address combinatorial optimization problems with a cardinality constraint, in which only a subset of variables end up having nonzero values. Firstly, we introduce a new heuristic pruning method that iteratively discards variables through a hybrid quantum-classical optimization step. Secondly, we analyse the use of soft constraints in the form of 'chemical potentials' to control the number of non-zero variables. We illustrate the power of both techniques using the problem of index tracking, which aims to mimicking the performance of a financial index with a balanced subset of assets. We also compare the performance of different state-of-the-art quantum variational optimization algorithms in our pruning method.D. Porras and J.J.

Public Programs at The New York Public Library.
No full textAmong the varied programs offered by the Library during the Spring, a series of lectures, Fables: From Aesop to La Fontaine, gets a page of recognition. The series is done by Marcel M. Gutwirth. It is meant to support and coincide with the Library's La Fontaine: The Power of Fables exhibition, co-curated by Paul LeClerc. The booklet features eight outstandingly-reproduced engravings by J.J. Grandville, including the cover engraving of the two high-society goats unable to pass through the doorway at the same time.Paul LeClerc
Coupling 3-Josephson junctions flux qubits for Adiabatic Quantum Computation
No full textQuantum Information in Spain ICE-7, Granada, 23-27 May 2022Many platforms have been proposed to implement Adiabatic Quantum Computation, from
superconducting circuits to trap ions. Nevertheless, it is still not clear how to obtain general
and fully tunable multi-qubit dynamics in any of them. General enough interactions would
allow, for instance, to reproduce the dynamics of non-stoquastic Hamiltonians, the ones for
which classical Monte-Carlo methods fail, opening the way to Universal Adiabatic Quantum
Computation.
In this talk, we analyse the coupling between two 3-Josephson junctions flux qubits and
present the effective Hamiltonian that controls the dynamics of the system when the two qubits
are coupled via a capacitor and/or via a Josephson junction [1]. We show that those two el-
ements allow engineering a fairly large family of qubit Hamiltonians with XX, YY and ZZ,
including fully non-stoquastic interactions and ultrastrong coupled ones. In addition, we dis-
cuss the capacitive coupling between a flux qubit and an LC-resonator [2] and show ultrastrong
coupling in a direction perpendicular to that of the commonly studied inductive coupling, leav-
ing the door open to the simulations of unexplored models in quantum optics.
