title: Consumer survey: second-hand smartphone use

description: This dataset contains responses from an online consumer survey conducted via Amazon Mechanical Turk in the United States (108 participants after data cleaning). The survey asked about previously owned mobile phones (including smartphones) that were originally obtained in used condition. The goal was to estimate the second-hand device use time and the final fate after ownership. Only devices no longer in possession were included, ensuring that any hibernation (inactive storage) period had already ended.

Fates were grouped into:
• SH — reused again as second-hand devices
• A — transferred to market agents (donation, trade-in, store returns)
• EoL — discarded into end-of-life waste streams
• Other — no clear response

Devices classified as “Other” were assumed to end up in EoL. Devices going to market agents were assumed to have a 50% chance of refurbishment. Therefore, all outcomes were ultimately allocated into: another reuse (SH) or End-of-Life (EoL).

Survey fields include: device acquisition year, ownership time (months), hibernation time (months), disposal route, and substitution behaviour (expected extra use of a new phone if second-hand was unavailable). The dataset also contains derived indicators: total lifetime in use (LT, years), hibernation time (HT, years), and additional use of a new phone (Extra, years). 

Data columns:
Timestamp
In which year did you obtain that device?
How did you obtain that device?
Where did you obtain that device?
What did you do with the device when you disposed of it?
For how long did you own the device in total? (months)
Did you store that device without actual use for more than a month before you disposed of it?
For how long did you store it without use prior to disposal? (months; enter 0 if always in use)
What do you expect — for how many extra months would you use the alternative new phone? (answered only if the respondent would buy a new phone and use it for longer)

Columns estimated after the survey:
LT (years)
HT (years)
Extra (years)

title: EEG signals of KMI levels of the right and left hands

description: This database contains raw EEG signals recorded during Kinesthetic Motor Imagery (KMI) at 0%, 40%, 70%, and 100% of the Maximal Voluntary Contraction (MVC) for the right and left hands. 

1. Subjects
50 healthy right-handed university students aged 17–30 years (23 females, 27 males; mean age = 21.78 ± 2.66 years). Participants were instructed to sleep at least 8 hours the night before the experiment and to avoid consuming caffeine, alcohol, or other psychoactive substances prior to the EEG session. Each subject performed KMI levels with only one hand.
*Subjects S01 to S25 performed the task with the left hand.
*Subjects S26 to S50 performed the task with the right hand.
2. Experimental Design
Each subject performed kinesthetic motor imagery (KMI) tasks involving hand-grip at 0%, 10%, 40%, 70%, and 100% of MVC. The experimental protocol for each condition consisted of 84 seconds of continuous EEG recording, including 10 repetitions of 4 s of task execution followed by 4 s of rest, with initial and final resting period. The resting periods correspond to level 0%. 
3. EEG Device
The used EEG headset was the Cognionics Quick-20m with 20 surface EEG electrodes were positioned at locations Fp1, Fp2, F7, F3, Fz, F4, F8, T7, C3, Cz, C4, T8, A2, P7, P3, Pz, P4, P8, O1, and O2.
4. Files
A file named info_subjects.xlsx containing the metadata of all participants is provided. This information was collected through a self-reported questionnaire and standardized psychometric tests applied individually to each subject prior to the EEG recordings.
Data Organization
Folder named LEFT (e.g., S01, S02, …, S25). KMI levels for the left hand.
Folder named RIGHT (e.g., S26, S27, …, S50). KMI levels for the right hand.
Files per subject:
4 Kinesthetic Motor Imagery (KMI) EEG files.
Each .csv file contains 20 columns, corresponding to the 20 EEG electrodes, and rows representing raw time samples.
All EEG signals are provided in a fully raw format, without filtering or pre-processing.
The first row of every .csv file contains the electrode name associated with each column.
This structure enables direct channel identification without requiring separate channel-mapping files.
The dataset is therefore ready for automated processing in Python, MATLAB, and C++, as well as in machine learning pipelines.

title: Analytical Data for Incremental Assembly of the Utuado Pluton, Puerto Rico: Evidence from Enclaves and Amphibole Geochemistry

description: This dataset contains all analytical results used in the study “Incremental Assembly of the Utuado Pluton, Puerto Rico: Evidence from Enclaves and Amphibole Geochemistry” that has been submitted for publication. The data integrate whole-rock major and trace element compositions, electron microprobe analyses of amphibole major elements, and LA-ICP-MS trace element analyses of amphiboles from enclaves and granodioritic host rocks within the Utuado Pluton.

Whole-rock geochemical data include major elements (XRF) and trace elements (ICP-MS) for samples collected from two field localities (Cañon Blanco Utuado and Río Jayuya Utuado). These data were used to characterize magma compositions, evaluate enclave–host relationships, and assess evidence for hybridization and melt extraction within the pluton.

Amphibole major element data (EPMA) document patchy zoning and intra-crystal chemical domains (Zones 1–3) that preserve discrete stages of crystallization and magma recharge. Amphibole trace element data (LA-ICP-MS) provide insight into melt evolution, mineral–melt partitioning behavior, and subduction-related geochemical signatures.

Together, these datasets support thermobarometric calculations, equilibrium-melt estimates, and the interpretation of magmatic processes including recharge, mingling, hybridization, and limited melt extraction during incremental pluton assembly. All files are provided in spreadsheet format with sample identifiers, analytical conditions where applicable, and variable descriptions to facilitate reuse.

title: Intra-host population dynamics of chikungunya virus in humans and naturally infected Aedes mosquitoes reveal transmission-driven diversity

description: RNA viruses often exhibit a high mutation rate, mainly because their RNA polymerases lack proofreading, which contributes to their genetic diversity. Arboviruses, which alternate between vertebrate and invertebrate hosts, are subjected to host-specific selective pressures and population bottlenecks, mainly within mosquito vectors. Although experimental studies have brought insights about their evolutionary dynamics, data from naturally infected vectors remain limited. Here, we investigated the intra-host genetic diversity of chikungunya virus (CHIKV-ECSA lineage) through whole-genome sequencing of 19 human- and 19 mosquito-derived genomes from the 2024 outbreak in São José do Rio Preto, Brazil. Our principal component analysis revealed a greater mutation number in mosquito-derived genomes, predominantly driven by low-frequency and unique variants. Overall, intra-host genetic diversity was significantly higher in mosquito-derived than in human-derived CHIKV genomes, and protein-coding regions showed host-specific patterns. We identified 303 mutations across all CHIKV genomes. Interestingly, shared mutations were predominantly classified as synonymous, whereas unique mutations were mainly non-synonymous. Gene-wide selection analyses indicated that purifying selection predominates across CHIKV genomes from both humans and mosquitoes, suggesting that most mutations, particularly non-synonymous ones, are deleterious and subject to purifying selection. However, in mosquito-derived CHIKV genomes, evidence of relaxed purifying selection and neutral evolution, in specific proteins, such as E3 and NSP3, respectively, was observed, in contrast to the stronger purifying selection observed in human-derived CHIKV sequences. Site-specific selection analyses corroborated these results, detecting negatively selected sites in human-derived genomes but not in mosquito-derived genomes for these specific proteins. Together, our results show that these host-specific differences enable mosquitoes to act as reservoirs of genetic diversity by maintaining non-synonymous variants, likely driven by genetic drift. At the same time, human hosts may impose stronger selective pressures, contributing to preserving the genome stability. This dynamic balance between diversification in vector populations and selective constraints in vertebrate hosts likely drives CHIKV evolution and adaptation.
