Measures of social cognition have now become central in neuropsychology, being essential for early and differential diagnoses, follow-up, rehabilitation a wide range conditions. With the scientific world becoming increasingly interconnected, international neuropsychological medical collaborations are burgeoning to tackle global challenges that mental health These initiatives commonly merge data across diversity populations countries, while ignoring their specificity.
The sensitivity of Global Navigation Satellite System (GNSS) receivers to ionospheric disturbances and their constant growth are nowadays resulting in an increased concern GNSS users about the impacts at mid-latitudes. geomagnetic storm June 2015 is example a rare phenomenon spill-over equatorial plasma bubbles well north from habitual. We study occurrence small- medium-scale irregularities North Atlantic Eastern Mediterranean mid- low-latitudinal zone by analysing amplitude scintillation...
The article focuses on practical recommendations for integrating ChatGPT into English language teaching. It examines key aspects of effectively using AI in the classroom, including setting goals, adapting materials to students' levels, and incorporating interactive tasks. emphasizes that should be used as a supplement traditional teaching methods, not replacement. details advantages ChatGPT, such personalized learning, development speaking skills, simplification material preparation,...
The flow of liquid metal inside the Earth's core produces geomagnetic field and its time variations. Understanding variability those deep currents is crucial to improve forecast variations may provide relevant information on dynamics. main goal this study extract characterize leading modes flows over centennial periods, assess their statistical robustness. To end, we use that invert from two models ('gufm1' 'COV-OBS'), apply principal component analysis singular value decomposition coupled...
Abstract. Three long-term temperature data series measured in Portugal were studied to detect and correct non-climatic homogeneity breaks are now available for future studies of climate variability. Series monthly minimum (Tmin) maximum (Tmax) temperatures the three Portuguese meteorological stations Lisbon (from 1856 2008), Coimbra 1865 2005) Porto 1888 2001) breaks. These series, together with average (Taver) range (DTR) derived from them, tested order breaks, using firstly metadata,...
Abstract. The Coimbra Magnetic Observatory (International Association of Geomagnetism and Aeronomy code COI) in Portugal has a long history observation the geomagnetic field, spanning almost 150 yr since first measurements 1866. These instrumental records provide very important information about variability elements indices, their trends cycles, can be used to improve our knowledge on sources that drive variations field: liquid core dynamics (internal) solar forcing (external). However,...
Abstract. The Coimbra Magnetic Observatory (COI), Portugal, established in 1866, has provided nearly continuous records of the geomagnetic field elements for more than 150 years. However, during its long lifetime inevitable changes to instruments and measurement procedures even relocation observatory have taken place. In our previous work (Morozova et al., 2014) we performed homogenization – elimination artificial measured declination series (D) period from 1866 2006. this paper continue on...
An updated dataset based on data from a GNSS receiver with the SCINDA software installed in Lisbon airport area are presented: new cover entire time interval December 2014 to February 2019, except for original 2015, which can be found version of paper. The consists 2 parts: (1) produced by SCINDA; (2) processed data. types described TEC, S4, ROTI and position (latitude, longitude, altitude) extracted Since was not calibrated when provisionally TEC is provided. processing done using dedicated...
The total ionospheric content (TEC) over the Iberian Peninsula was studied using data from two locations obtained both by GNSS receivers and an ionosonde. principal component analysis applied to TEC allowed us extract main modes. Each mode is characterized daily variation of a certain type (PC) its amplitude for each day (given empirical orthogonal functions, EOF). variations these modes as well original were in relations four strongest geomagnetic storms 2015 three disturbances lower...
Abstract. The Coimbra Magnetic Observatory (COI), Portugal, established in 1866, provides almost continuous records of the geomagnetic field elements for more than 150 years. However, during its long lifetime inevitable changes instruments, measurement procedures and even re-location took place. In our previous work (Morozova et al., 2014) we performed homogenization – elimination artificial measured declination series (D) period from 1866 to 2006. this paper continue applying absolute...
Cosmic rays of a wide range energies are arriving permanently to the Earth coming from Sun or beyond our solar system. Their study is interest for many fields research. A high granularity and time resolution cosmic ray tracking detector, TRAGALDABAS, based on timing RPC cells, has been recently installed at Faculty Physics Univ. Santiago de Compostela, in Spain, order go deeper into understanding surface. In this article, layout main performances detector shown together some expected...
Research on cosmic rays is of big interest either for getting a better understanding about their origin and properties or because they offer very valuable information the galactic, solar Earth's environment.

An ionospheric response at middle latitudes to geomagnetic storms is not yet very well understood. Total electron content (TEC) variations associated with eight strong between 2015 and 2022 obtained from GNSS receivers in the western area of North Atlantic (Portuguese continental insular territory) are studied an attempt fill this gap.
