The GEOTRACES Intermediate Data Product 2017
(Elsevier, 2018)
The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The ...

Motivation and feelings of competence among university students in introductory physics
(Springer, 2022)
This work analyzes whether there is a cognitive bias between the ideal perception of the skills and the real performance in an introductory physics class, and additionally, whether predictions of students’ performance are ...

Bell nonlocality with intensity information only
(American Physical Society, 2020-09-01)
We address the problem of detecting bipartite Bell nonlocality whenever the only experimental information are the intensities produced in each run of the experiment by an unknown number of particles. We point out that this ...

210Po levels and distribution in different environmental compartments from a coastal lagoon. The case of Briozzo lagoon, Uruguay
(Elsevier, 2020)
This paper presents the levels and distribution of 210Po in different compartments of a coastal lagoon on the east coast of Uruguay (South America). Activity concentrations of 210Po have been obtained in different ...

Device-independent quantum key distribution based on Bell inequalities with more than two inputs and two outputs
(American Physical Society, 2021-05-28)
Device-independent quantum key distribution (DI-QKD) offers the strongest form of security against eavesdroppers bounded by the laws of quantum mechanics. However, a practical implementation is still pending due to the ...

Significant loophole-free test of Kochen-Specker contextuality using two species of atomic ions
(American Association for the Advancement of Science, 2022-02-09)
Quantum measurements cannot be thought of as revealing preexisting results, even when they do not disturb any other measurement in the same trial. This feature is called contextuality and is crucial for the quantum advantage ...

Monolithic integration of graphene in SiC radiation sensors for harsh-environment applications
(Trans Tech Publications, 2022)
Due to their low leakage current, low noise levels, high thermal conductivity, and potential radiation hardness, SiC devices offer various advantages over Si devices in certain applications. As a result, they are being ...

Effects of particle size and field orientation on the yield stress of magnetostabilized fluidized beds
(American Chemical Society, 2012-05-23)
In this work, we present experimental measurements of the yield stress of gas-fluidized beds of magnetizable particles stabilized by an externally imposed magnetic field. Powder samples consist of spherical magnetite ...

Building and environmental acoustics in obsolete residential neighbourhoods: The case of San Pablo, Spain
(Elsevier, 2023-09)
In order to establish an agreement between the objectives of acoustic quality in the outdoor environment and the acoustic insulation in a building as required in the current legislation in Spain, the acoustic insulation ...

Geometric driving of two-level quantum systems
(American Physical Society, 2020)
We investigate a class of cyclic evolutions for driven two-level quantum systems (effective spin 1/2) with a particular focus on the geometric characteristics of the driving and their specific imprints on the quantum ...
