Data from the article "F. Ortin, G. Facundo, M. Garcia. Analyzing syntactic constructs of Java programs with machine learning. Expert Systems with Applications (215), pp. 119398-119414, 2023. https://doi.org/10.1016/j.eswa.2022.119398", The massive number of open-source projects in public repositories has notably increased in the last years. Such repositories represent valuable information to be mined for different purposes, such as documenting recurrent syntactic constructs, analyzing the particular constructs used by experts and beginners, using them to teach programming and to detect bad programming practices, and building programming tools such as decompilers, Integrated Development Environments or Intelligent Tutoring Systems. An inherent problem of source code is that its syntactic information is represented with tree structures, while traditional machine learning algorithms use n-dimensional datasets. Therefore, we present a feature engineering process to translate tree structures into homogeneous and heterogeneous n-dimensional datasets to be mined. Then, we run different interpretable (supervised and unsupervised) machine learning algorithms to mine the syntactic information of more than 17 million syntactic constructs in Java code. The results reveal interesting information such as the Java constructs that are barely (and widely) used (e.g., bitwise operators, union types and static blocks), different language features and patterns mostly (and barely) used by beginners (and experts), the discovery of particular types of source code (e.g., helper or utility classes, data transfer objects and too complex abstractions), and how complexity is an inherent characteristic in some clusters of syntactic constructs., This work has been partially funded by the Spanish Department of Science, Innovation and Universities: project RTI2018-099235-B-I00. The authors have also received funds from the University of Oviedo, Spain through its support of official research groups (GR-2011-0040).

Se actualiza el panorama de la segregación ocupacional en España para el año 2022 y se examina su evolución y factores determinantes a lo largo del último siglo. Para ello, se emplean los índices más utilizados en la literatura: el Índice de Gini (y las curvas de Lorenz), el Índice de Desigualdad y el Índice de Desigualdad Descompuesto (que neutraliza el efecto de la estructura), utilizando datos censales para asegurar un alto nivel de desagregación. Los factores que influyen en la segregación se evalúan mediante regresiones multinomiales y se contrastan a través de efectos marginales (EPA, 2011 y 2021). Los resultados muestran que la segregación no experimenta una disminución significativa, dado que aumenta el peso de las ocupaciones con mayor grado de segregación mientras que disminuye en las ocupaciones que ya presentaban un proceso de integración. Asimismo, se verifica una relación inversa entre ingresos y nivel educativo en las ocupaciones predominantemente masculinas y femeninas

Data from the article "F. Ortin, M. Garcia, B. Garcia Perez-Schofield, J. Quiroga. The StaDyn Programming Language. SoftwareX (20), pp. 101211-101222, 2022. https://doi.org/10.1016/j.softx.2022.101211", Hybrid static and dynamic typing languages are aimed at combining the benefits of both kinds of languages: the early type error detection and compile-time optimizations of static typing, together with the runtime adaptability of dynamically typed languages. The StaDyn programming language is a hybrid typing language, whose main contribution is the utilization of the type information gathered by the compiler to improve compile-time error detection and runtime performance. StaDyn has been evaluated as the hybrid typing language for the .Net platform with the highest runtime performance and the lowest memory consumption. Although most optimizations are performed statically by the compiler, compilation time is yet lower than the existing hybrid languages implemented on the .Net platform., The StaDyn programming language was partially funded by Microsoft Research, United States with the project entitled Extending Dynamic Features of the SSCLI, awarded in the Phoenix and SSCLI, Compilation and Managed Execution Request for Proposals. It was also funded by the Spanish Department of Science, Innovation, and Universities (project RTI2018-099235-B-I00) and the University of Oviedo, Spain (GR-2011-0040).

This dataset corresponds to the measurements of two microstrip patch antennas, collected using the facility described in [1]. The available measurements contained within the dataset allow a complete characterization of the field radiated by these antennas. These fields can be introduced in enhanced microwave imaging algorithms that consider the field radiated by the transmitting and receiving antennas of the microwave imaging system [2] (modified Delay and Sum algorithm), [3] (modified Phase Shift Migration imaging algorithm). The patch antennas that are characterized are the ones presented in [4]. The files "Emeas_leftPatch_z30cm.zip" and "Emeas_rightPatch_z30cm.zip", correspond to the copolar component (Ex component) of the electric field radiated by the patch antennas (left and right as depicted in the figure “PictureDataset.png”). More precisely, it corresponds to the S21 parameter, which is proportional to the electric field radiated by the patch antenna. Measurements were conducted within the frequency range from 22 GHz to 28 GHz, with a frequency step of 15 MHz. Measurements were collected on a domain of size Lx × Ly = 70 cm × 70 cm, discretized every δx,y = 5 mm (0.42 wavelengths at the center frequency of 25 GHz). The distance between the patch antenna (antenna under test) and the measurement plane was 30 cm. An Open-Ended Waveguide was used as probe antenna. The measured electric field was backpropagated from the measurement plane to the patch antenna aperture plane using the backpropagation algorithm described in [5]. The electric fields on the aperture plane are provided in the files “Eap_leftPatch.zip” and “Eap_rightPatch.zip” for the left and right patch antennas, respectively. The aperture fields were calculated on a planar domain having the same size as the measurement plane, that is, Lx × Ly = 70 cm × 70 cm, and also discretized every δx,y = 5 mm. [1] A. Arboleya, Y.
