Knapping experiment in the frame of the "MSCA Western European Acheulean Project - WEAP" (748316), made at UCL in March 2019. The aim was to reproduce handaxes, paying special attention to the gestures, number of blows and how knapper turns the blank to produce the instrument.

Data collected in the framework of the ERC project "The sound of special places: exploring rock art soundscapes and the sacred" (acronym: Artsoundscapes, Grant Agreement No. 787842). The project focuses on the relationship between archaeoacoustics and rock art. The audio files are the impulse responses in different formats gathered in the Palomas I cave in Facinas (Tarifa, Cádiz, Spain) and some auralization examples. The tables include the acoustic data derived from those impulse responses.

This dataset contains the information on our recent body of work on wireless magneto-ionics by bipolar electrochemistry approach and all the relevant data files. So far, magneto-ionics has been achieved through direct electrical connections to the actuated material. Here we evidence that an alternative way to reach such control exists in a wireless manner. Induced polarization in the conducting material immersed in the electrolyte, without direct wire contact, promotes wireless bipolar electrochemistry, an alternative pathway to achieve voltage-driven control of magnetism based on the same electrochemical processes involved in direct-contact magneto-ionics. A significant tunability of magnetization is accomplished for cobalt nitride thin films, including transitions between paramagnetic and ferromagnetic states. Such effects can be either volatile or non-volatile depending on the electrochemical cell configuration. These results represent a fundamental breakthrough that may inspire future device designs for applications in bioelectronics, catalysis, neuromorphic computing, or wireless communications.

This dataset comprises the articles incorporated in the meta-analysis. In total, 78 articles underwent thorough review, and 67 were disqualified either because they lacked preoperative or postoperative samples or because they contained data from patients with metastatic conditions. Furthermore, one additional study sourced from the references list was integrated into the analysis before quantitative data examination. Ultimately, 12 articles were encompassed in the meta-analysis, encompassing a total of 413 patients diagnosed with potentially resectable pancreatic ductal adenocarcinoma (PDAC). The study's inclusion period spanned from 1998 to 2021. Patients were included in the quantitative analysis in accordance with the intention-to-treat principle. Notably, 17 patients (4.1%) were eventually reclassified as stage IV due to the presence of distant lymph node positivity observed during the analysis of resected specimens, discrepancies in CT scans, or unforeseen surgical findings. A unanimous decision was reached to incorporate these stage IV patients into the meta-analysis in order to mirror a real-world clinical scenario and facilitate an intention-to-treat analysis

Data collected in the framework of the ERC project "The sound of special places: exploring rock art soundscapes and the sacred" (acronym: Artsoundscapes, Grant Agreement No. 787842). The project focuses on the relationship between archaeoacoustics and rock art. The attached files correspond to 1) the audio files of the impulse responses collected at the rock art sites of Sandra shelter (Kamberg, South Africa), and Bamboo Hollow III and Wilcox shelter (Giant’s Castle, South Africa), all of them in the Drakensberg mountain range, 2) the corresponding ambient sounds registered on each of the three sites, 3) the resulting audio tracks when the ambient sound is reproduced in the immersive audio laboratory of the Faculty of Psychology, and 4) a Matlab script for the extraction of the psycoacoustical parameters presented on the publication.

This study investigated the potential parameters limiting the stable eCO2RR to formate using In catalyst over 72 h operation. We showed that in order to achieve a stable and efficient eCO2RR, the interrelation between few operational parameters needs to be taken into consideration. In the case studied here being exemplarily for interfacing eCO2RR and bioproduction, a Formate concentration increase in the catholyte and change in conductivity of the catholyte may not directly influence the formate production rate and coulombic efficiency. Yet, they affect the actual cathodic potentials, leading to fluctuations in formate production rate (maximum ± 0.03 mmol h−1 cm−2 at stable operation at each condition) and coulombic efficiency (max. ± 40% at stable operation at each condition) after reaching the certain value of formate concentration and conductivity in the catholyte (ca. 70 mM and 21 mS cm−1, respectively). Therefore, the concentration should be kept below such a value which can be easily achieved by process steering allowing balancing the rates of eCO2RR and microbial consumption. In addition, the stability of the In catalyst needs to be improved in order to operate long-term stable eCO2RR. Confirmed by the increase observed in In corrosion rate at more negative potentials and change in the pH values, H2 generation at the surface could lead to the damage at the surface of the electrode coated by the electrocatalyst. Therefore, the durability of the electrode can be closely related to the electrode potential. One can consider less negative potentials to decrease the catalyst leaching but to increase the HER. However, that would consequently decrease formate production rate from eCO2RR. Alternatively, more C1-compound selective electrodes can be explored and used.

A multi-environment dataset (height and survival at age 20) consisting of 123 populations of Pinus pinaster evaluated in 15 trials is presented. Four marker-based, previously defined neutral classifications along with two ad hoc climate-based categorizations are aslo included for the purpose of summarizing plasticity patterns in the species.

This dataset contains the information on our recent body of work on the effect of the deposition of ZnO coating on degradation rate of FeMn porous alloys. Fe-based alloys are being studied as potential candidates for biodegradable implants; however, their degradation rates remain too slow. To accelerate biodegradation while simultaneously hindering biofilm formation, a ZnO coating was deposited onto porous equiatomic FeMn alloy discs by sol-gel method using dip coating. The effect of the ZnO coating on the microstructure, biodegradability, cytocompatibility, and antibacterial properties were investigated. Biodegradability experiments were performed by immersing the specimens in Hank's balanced salt solution and measuring ion release after up to 28 days of immersion. The experiments showed an increased degradation of the FeMn/ZnO sample due to Fe segregation towards the grain boundaries, formation of iron-manganese oxide, and limited formation of degradation products on ZnO. Further, indirect Saos-2 cell cytotoxicity testing in 24 h sample-conditioned media showed no significant cytotoxicity in concentrations equal to or below 50 %. In addition, the total biofilm biovolume formed by Staphylococcus aureus on the FeMn/ZnO surface was significantly reduced compared to the uncoated FeMn. Taken together, these results show that the ZnO coating on FeMn improves the degradation rate, maintains cytocompatibility, and reduces biofilm accumulation when compared to an uncoated FeMn alloy.
