This dataset contains multimodal neuroscience data collected from 25 adult Thy1-GCaMP transgenic mice (~8–12 months of age) undergoing photothrombotic (PT) stroke, generated to assess functional and behavioral changes at acute and chronic timepoints following ischemic injury. Data were acquired from a single biological source — live mice — with tissue samples subsequently processed for post-mortem histological analysis. Three data modalities are included: widefield calcium imaging (WFCI) capturing cortex-wide neural activity via the genetically encoded calcium indicator GCaMP; behavioral data from the cylinder rearing test, which quantifies forelimb asymmetry as a measure of sensorimotor deficit; and histological data comprising both Cresyl Violet (Nissl) staining for lesion visualization and immunohistochemistry (IHC) for protein-specific labeling. Each mouse was assessed at three experimental timepoints: baseline (pre-stroke), acute (24 hours post-PT stroke), and chronic (one week post-PT stroke), with histology collected only at the post-chronic endpoint. The dataset is hierarchically organized under a top-level /data directory containing three primary modality folders: /behavior, /WFCI, and /histology. The /behavior folder is organized by mouse ID (e.g., /M01) and then by timepoint (/bsl, /acute, /weekone), containing raw video recordings, Excel-format scoring sheets, and aggregated GraphPad Prism files summarizing results across all animals. The /WFCI folder is subdivided into three processing tiers — /Raw (unprocessed imaging files), /Tier1_Derived (intermediate processed data), and /Tier2_SourceData (analysis-ready outputs organized by mouse and timepoint) — supporting reproducibility from raw acquisition through final analysis. The /histology folder contains two subfolders, /cresyl_violet and /IHC, holding stained tissue section images. File formats include TIFF images for histology, CSV and XLSX for behavioral scoring, and standard video formats for raw behavior recordings. The organizational rationale — mouse ID → modality → timepoint — enables straightforward longitudinal comparisons within subjects and cross-sectional comparisons across the cohort. Data were generated by Jake Lee and Arnav Ajay Jadav in the Landsness Lab, Department of Neurology, Washington University in St. Louis (contact: jake.l@wustl.edu), and are suitable for analyses of stroke-induced changes in cortical dynamics, motor behavior, and structural pathology.

La Escala de Depresión basada en el Criterio Diagnóstico Axial para la Depresión fue desarrollada por Ramos-Brieva, Cordero y Gutiérrez-Rojas (2009) con el propósito de evaluar los componentes esenciales de la experiencia depresiva desde una perspectiva dimensional. El instrumento se fundamenta en la idea de que la depresión no debe entenderse únicamente como una categoría diagnóstica, sino como un continuo de gravedad que puede manifestarse en diferentes niveles. La escala está compuesta por siete ítems que evalúan áreas consideradas nucleares en la depresión: motivación o interés por las cosas, impulso para la actividad, capacidad de experimentar placer, percepción del trabajo cotidiano, estado de ánimo, energía corporal y cualidad subjetiva de la experiencia emocional. Cada dimensión se responde mediante una escala de 10 puntos entre dos adjetivos opuestos. Los estudios reportan adecuadas propiedades psicométricas, destacándose una sensibilidad de 0.93, especificidad entre 0.82 y 0.92, consistencia interna de α = 0.92 y una fiabilidad de κ = 0.76, lo que respalda su utilidad para la evaluación de síntomas depresivos. La puntuación total oscila entre 7 y 70 puntos. Los puntajes más altos indican una mayor intensidad de síntomas depresivos. La interpretación propuesta clasifica los resultados en tres niveles: bajo (7–28), medio (29–49) y alto (50–70). Características psicométricas: • Sensibilidad: 0.93 • Especificidad: 0.82–0.92 • Consistencia interna: α = 0.92 • Fiabilidad: κ = 0.76 Fundamento teórico: El criterio diagnóstico axial se basa en un enfoque dimensional que busca superar las limitaciones de los sistemas categóricos tradicionales como DSM y CIE, permitiendo una evaluación más precisa de la heterogeneidad clínica de la depresión.

This dataset contains pseudonymized vehicle-tracking telemetry from 100 vehicles fitted with Teltonika FMB920 tracking units and monitored across Pakistan by a commercial vehicle-tracking provider. It spans twelve consecutive months (March 2024-February 2025) and comprises 61,331,270 message-level records. Vehicle positions fall within roughly 24.2-35.9° N and 66.6-75.7° E. The dataset was compiled to provide an openly shareable, privacy-preserving record of real fleet operation for research in intelligent transportation and geospatial analysis. Typical uses include reconstructing per-vehicle trajectories and trips, analysing speed, stop and ignition patterns, and assessing GPS-fix quality. The data are also suitable for developing or benchmarking anomaly-detection and trust-scoring methods for Internet-of-Things systems. The records are supplied as twelve monthly archives named with ISO year-month dates (telemetry_2024-03.zip through telemetry_2025-02.zip); each holds one CSV file with the matching name (telemetry_2024-03.csv through telemetry_2025-02.csv). Each row is a single message from one device and has 15 fields: stable vehicle and device pseudonyms, device model, GpsTime, message identifier, longitude (X), latitude (Y), speed, travel direction, altitude, visible-satellite count, ignition state, main battery voltage, packet-validity flag, and Canal. GpsTime is the DateTime when the packet was created by the device. Canal indicates if the message is regular (1) or in response to server ping (0). Vehicle registration numbers and device IMEIs were removed before release and replaced with stable pseudonyms. Column definitions are given in data_dictionary.csv. A 100,000-row sample is provided in sample.csv for quick inspection without downloading the full archives. It uses the same 15 fields as the monthly files and contains 10,000 records from each of ten vehicles (vehicle_020, vehicle_037, vehicle_044, vehicle_047, vehicle_051, vehicle_075, vehicle_076, vehicle_077, vehicle_079 and vehicle_081), all drawn from the first five days of March 2024 (1-5 March 2024). The identifiers Vehicle_Id and Device_Imei_Id are stable across all months, so a vehicle or device can be followed through the whole period. Reporting cadence is not fixed: intervals between consecutive messages vary by vehicle and vehicle state, and Ignition_Status and VectorSpeed help separate moving, idling and parked periods. The data carry no event labels (attacks, faults, anomalies), so any labels needed for supervised tasks must be supplied by the user. The release also includes records_per_vehicle.csv, which gives one total record count per vehicle for all 100 vehicles and is ordered by Vehicle_Id, and number_of_vehicles_and_records_per_month.csv, which lists each monthly archive and contained CSV with vehicle counts, record counts, and a total row.
