This study conducts research on deepfakes technology evolution and trends based on a bibliometric analysis of the articles published on this topic along with six research questions: What are the main research areas of the articles in deepfakes? What are the main current topics in deepfakes research and how are they related? Which are the trends in deepfakes research? How do topics in deepfakes research change over time? Who is researching deepfakes? Who is funding deepfakes research? We have found a total of 331 research articles about deepfakes in an analysis carried out on the Web of Science and Scopus databases. This data serves to provide a complete overview of deepfakes. Main insights include: different areas in which deepfakes research is being performed; which areas are the emerging ones, those that are considered basic, and those that currently have the most potential for development; most studied topics on deepfakes research, including the different artificial intelligence methods applied; emerging and niche topics; relationships among the most prominent researchers; the countries where deepfakes research is performed; main funding institutions. This paper identifies the current trends and opportunities in deepfakes research for practitioners and researchers who want to get into this topic.

[ENG] Database of a catalog of Hispanic Roman amphorae with more than 90 items that include their description, chronology, typological evolution, metrology, origin, geographical distribution, content, epigraphic repertoire, archaeometry, related bibliography and images. The amphorae come from the provinces of Tarraconensis, Baetica and Lusitania and are dated between the 3rd century BC and the 7th century AD.

Este dataset contiene el análisis de las páginas webs de 50 agencias de comunicación y relaciones públicas que operan en España a partir del ranking de El Publicista (2022). El estudio también incluye el análisis de 43 campañas de Responsabilidad Social Corporativa (RSC) que estas agencias han desarrollado para sus clientes, así como 23 campañas de RSC que han implementado como acciones propias. El período de análisis fue del 1 de diciembre de 2022 al 30 de enero de 2023. Se ha desarrollado un análisis de contenido cuantitativo (análisis de frecuencias) y cualitativo (descriptivo-interpretativo). Conclusión: La mayoría de las consultoras de comunicación y RRPP (el 74,5%) se presentan como de servicios plenos. Solo un 2% está especializada en RSC, mientras que el 23,5% restante lo está en otras áreas. No obstante, el 42% de estas consultoras manifiestan en sus webs ofrecer servicios de RSC y el 60% de ellas difunde casos de éxito de RSC ejecutados para alguno/s de sus clientes. Se han identificado 43 campañas. El 27,3% de las organizaciones promotoras de estas campañas son ONGs o entidades del tercer sector y el 56,8% del total están ligadas a la propia actividad del cliente. La mayoría está vinculada con el ODS 3 (Salud y bienestar). Sin embargo, únicamente un 12% de las agencias manifiesta en su web contar con profesionales especializados en RSC. Asimismo, solo un 34% de las consultoras implementan acciones de RSC propias (23 campañas), con un 47,8% de estas campañas adoptando estrategias de colaboración pro-bono con entidades sin ánimo de lucro. Por ámbito de RSC, la mayoría de las acciones propias son de cariz social (60,9%), siendo de carácter medioambiental solo el 8,6% y con un 30,4% abarcando ambos ámbitos. La mayoría está vinculada con el ODS 5 (Igualdad de género).

In this dataset, one can find all the input files, and some key output files, for the first-principles density functional theory (DFT) calculations performed for the article entitled "Facet-engineered TiO2 drives photocatalytic activity and stability of supported noble metal clusters during H2 evolution", which has been authored by: Yufen Chen, Lluís Soler, Claudio Cazorla, Jana Oliveras, Neus. G. Bastús, Víctor Puntes, and Jordi Llorca.

This dataset contains the information on our recent work on multilevel magnetic synapses for neuromorphic applications and all the relevant data files. In the present work, we exploit voltage-driven nitrogen ion motion in transition metal nitride (CoFeN) thin films (i.e., nitrogen magneto-ionics) to emulate biological synapses. In the proposed device, we have realized distinct multilevel non-volatile magnetic states for analog computing and multi-state storage. Moreover, essential synaptic functionalities of the human brain have been successfully simulated. The device exhibits an excellent synapse with a remarkable retention time (∼ 6 months), high switching ratio and large endurance (∼103), for hardware implementation of NC. This research provides new insight into exploiting magneto-ionic-based synaptic devices for spin-based neuromorphic systems.

This dataset contains the screenshots of the technical walkthrough of profile creation of 12 Mobile Dating Apps (MDAs). Screenshots have been anonymized when necessary for privacy protection. The dataset is divided by app and by data collection timeframe. Additionally, the dataset contains a .txt file of fieldnotes and a .xlsx table that summarizes findings.

We undertook a cross-sectional study in March-April 2022 with a target sample size of 2,000 adults aged 50-79 years old residing in Spain. Sample selection was randomized using Spanish landline telephone contacts. The sample size was random and we aimed at a proportional sample to the population according to the following variables: municipality size (under 10,000, between 10,000 and 50,000, between 50,000 and 100,000 and over 100,000 inhabitants), age (50-64 and 65-74), sex (men, women), and highest educational attainment (four educational groups are distinguished). The field work was undertaken by Opiniòmetre. Data were collected by trained interviewers using a standardized computer-assisted telephone interview (CATI). Interviews took place between March 2nd and April 12th and lasted, approximately, 15 minutes. Because of the different timing of filling the quotas by educational attainment and some difficulties in reaching the lowest educated groups, the quotas for the highest educational groups were opened in the last days of the fieldwork. When picking up the telephone, the interviewer introduced him/herself on behalf of Opiniòmetre, briefly explain the project aims and the data protection regulations (confidential, anonymous and uniquely used for statistical purposes) (Appendix 1). The interview was in Spanish or either in Spanish or Catalan in the Catalan speaking regions, upon the choice of the interviewee. The sample was collected using a Computer Assisted Telephone Interviewing (CATI). In total 49,742 telephone numbers were used. Most telephone numbers could be reached within the first three attempts (45,425, 91.3%), whereas up to 15 attempts were done in order to get in contact others. Out of the used telephone numbers, 2,011 (4.0%) have completed the interview, 29,077 (58.5%) could not be reached, 15,537 (31.2%) rejected to participate, 2,570 (5.2%) could not continue the interview as they were either out of the age range or the quotas were fulfilled, and a remaining 1.1% did not participate for other reasons (company telephone, second residence). These are reasonable numbers for a study of such characteristics given the limited age range and the quotas to be fulfilled. The DDHealth questionnaire has four main modules. The first module is the sociodemographic module, and next to age and sex, there are questions related to the socioeconomic position such as highest educational attainment or financial constraints. The second module focuses on digital divide aspects such as internet use, frequency of internet use or use of internet for medical purposes. The third module contains questions related with health and wellbeing, for instance self-reported health, chronic conditions or smoking. Finally, the last module contains the 16 questions belonging to the short health literacy questionnaire from the EU (HLS-EU-Q16).

Data collected in the framework of the ERC project "The sound of special places: exploring rock art soundscapes and the sacred" (Grant Agreement No. 787842). The project focuses on the relationship between archaeoacoustics and rock art. The audio files are the impulse responses gathered in the Tajo de las Figuras shelter (Cádiz – Spain) and some auralisation examples. The tables include the acoustic data derived from those impulse responses.
