This dataset contains a structured catalogue of Instagram posts published on the official Instagram account of Afroditi Latinopoulou between 7 December 2024 and 29 January 2026. The dataset includes 127 unique posts, with each entry containing the publication date, post URL, and a caption-derived heading to facilitate identification of the post. The dataset was compiled for qualitative and computational content analysis. Publication dates were independently verified from the Instagram media identifiers embedded in each post shortcode, and all links were audited to ensure that each record refers to a unique post.

Dataset description This data article describes an open, plant-level dataset of renewable energy curtailment in Chile's National Electricity System (Sistema Eléctrico Nacional, SEN), consolidating the public curtailment records published by the Chilean National Electricity Coordinator (Coordinador Eléctrico Nacional, CEN) into validated relational tables. The daily table contains 293,678 records and the hourly table 6,906,761 records, both covering the continuous period from 1 January 2022 to 31 May 2026 (1,612 days, built from all 53 monthly CEN reports) with no missing days. Records span 300 generation plants across four technologies: solar photovoltaic (75 plants), wind (56), run-of-river hydropower (140) and reservoir hydropower (29); hydropower curtailment records are present from June 2024 onward, with hourly hydropower detail from July 2024. Each plant is linked to a metadata registry fully matched to the CEN installation catalogue (300 of 300 plants) with 19 fields including official CEN identifier, installed capacity (MW), owner, region, province, municipality, geographic coordinates, commissioning date, connection point and regulatory classification; the matching method is recorded per plant. Days and hours without curtailment are stored explicitly as zero-valued records (49.8% of daily and 83.6% of hourly rows). The processing pipeline documents eight classes of errata identified in the original CEN publications (monthly reports and installation catalogue) using deterministic, code-verifiable rules (including a structural continuity check that detects omitted calendar days even when they carry zero energy), and two omitted days were recovered from the corresponding monthly hourly sheets with independent cross-checks against the source files' total columns. Every rule, affected file and treatment is documented in an accompanying errata log, and the original unmodified source files are preserved with SHA-256 checksums. Annual totals from the daily table match the CEN official summary exactly (difference 0.000 GWh) in all five years, and aggregate 2022 values reproduce the curtailment figures reported by Fraunhofer Chile with a deviation of 0.07%. In a census month-by-month reconciliation of hourly sums against daily totals, 50 of 53 months agree within 1% (42 exactly); the three remaining months reflect documented inconsistencies within the CEN's own publications. The dataset totals 19,030 GWh of recorded curtailment (1,471 GWh in 2022; 2,667 in 2023; 6,224 in 2024; 6,205 in 2025; 2,463 from January to May 2026). The deposit includes CSV and Parquet formats, a data dictionary, the errata log and integrity checksums; the processing pipeline is available in the companion repository. The data enable research on renewable energy integration, curtailment forecasting, uncertainty quantification and distribution-shift analysis in a national power system that experienced large-scale battery energy storage deployment during 2025. Cut-off: 2026-05-31. Source: public information of the Coordinador Electrico Nacional (CEN), Chile. A data article describing this dataset is in preparation for submission to Data in Brief.

This dataset and reproducibility package supports a retrospective mixed-methodsstudy of technology-enhanced assessment in STEM education using X-raydiffraction interpretation as the disciplinary context. Supplementary Data S1 contains anonymized report-level rubric scores for 11group laboratory reports, including scores assigned by the principal andexternal evaluators, variable definitions, statistical summaries, datasets usedfor figure generation, and validation checks. Supplementary File S2 contains the complete R script, reproducibilityinstructions, session information, validation results, machine-readablestatistical outputs, and reproducible versions of Figures 4–6. A copy ofSupplementary Data S1 is included within the reproducibility package to allowstandalone execution of the R workflow. The deposited materials contain only anonymized group-level report identifiers(E1–E11). They do not include student names, institutional identifiers,individual grades, or original laboratory reports. The materials are associated with a manuscript examining the distinctionbetween operational use of professional analytical software and criticalevaluation of software-generated outputs in STEM education.

First invented in 2012, Two-Way Cybernetic Morse Codex Communication represents the next generation of Morse code in an algorithmic format. It operates via specialized algorithms embedded within everyday social media applications (e.g., Instagram) to transmit encrypted communications for analysis and response between intended parties. This system can operate solely through cellular notification alerts without relying on content from third-party vendors by employing machine algorithm methodology. The operation can run in a fully automated mode or be manually operated by an agent at a base station, depending on the classified circumstances of the mission. These operations function on distinct tiers within platforms and applications. Each scenario requires individualized analysis to determine severity levels and execution protocols.
