Replication Data for: Advanced Leak Detection Methods for Belowground Natural Gas Pipeline Leaks: Evaluation under Diverse Environmental and Operational Condition
Final Report: Source Water Study for the Hamilton Pool Area, Western Travis County, Texas
The Hamilton Pool Source Water Protection Study investigated the crucial groundwater resources that sustain the existing domestic water supply, and the unique ecological and recreational areas of Hamilton Pool Preserve and Reimers Ranch Park in western Travis County, Texas. These natural landmarks rely heavily on groundwater, which is increasingly threatened by a growing population, rising demand for water supplies (through pumping), and the impacts of a changing climate, including increased severe droughts. The study enabled the Southwestern Travis County Groundwater Conservation District to create an aquifer management zone and provide science-based recommendations that will inform and help guide policies and strategies aimed at preserving the region’s groundwater resources

Latin American Press Review, Program 1973-10, 1973 May 24
Part I: Reports on the impact of the May 4th kidnapping of a US consul in Mexico by the Fuerzas Revolucionarias Armadas del Pueblo (FRAP), a previously unknown guerrilla organization. FRAP demanded the release of prisoners and a ransom for the consul's release, garnering widespread attention and sympathy for their manifesto criticizing social injustices in Mexico. In Brazil, the Minister of Agriculture resigned, citing policies favoring foreign-owned industries over Brazilian farmers. The Fiat Auto Corporation's controversial deal with the Minas Gerais state government has raised concerns about transparency and foreign influence in Brazilian affairs. In Costa Rica, President Jose Figueres' New York bank account saw a significant increase in funds since granting refuge to American financier Robert Vesco, who is under indictment in the US for financial fraud. In Peru, the government has taken control of the fishmeal industry to address inefficiencies and reduce external dependency. Uruguay's proposal to limit trade union rights has faced opposition, and the military's attempt to strip parliamentary privileges from Senator Enrique Erro has faced resistance. Prensa Latina has expressed discontent with the human rights situation in Uruguay, citing arrests, torture of detainees, and new repressive legislation. Part II: The Latin American Press Review features the official report of the ad-hoc committee on Guatemala, following a resolution at the 1971 National Latin American Studies Association meeting to investigate terrorism in Guatemala. The report highlights the surge in right-wing terror in 1971 under Colonel Carlos Arana Osorio's government. The violence targeted moderate opposition figures, intellectuals, students, and even some businessmen. The National University of San Carlos was a prime target, with numerous students, professors, and university officials facing threats, arrests, and assassinations. The report links US involvement to the situation, detailing military and police assistance, which has been criticized for its political implications. Despite a relatively calmer 1972, rightist political violence persisted, with documented disappearances and human rights violations, indicating a systemic repression in Guatemala since 1954.

Replication Data for: Split Nitrogen Application to Soil Improves Corn Agronomic Performance and Nitrogen Use Efficiency
Corn (Zea mays L.) production requires substantial nitrogen (N) during the grain-filling reproductive stages. Delaying split N application until the silking stage (R1) may improve agronomic performance and reduce environmental N losses. This study evaluated the effects of split and reduced N applications on corn growth, yield, soil residual nitrogen, and nitrogen use efficiency (NUE) under rainfed conditions in Central Texas over two contrasting seasons. Ten treatments were tested, including split applications ranging from 100:0 to 50:50 (planting:R1) and reduced rates at 50% and 25% of the full N recommendation. In 2021, with adequate rainfall, split applications had no significant effect on aboveground biomass or grain yield, although delaying 50% of N to R1 reduced leaf area index (LAI) and chlorophyll content. In 2022, under severe drought, overall plant performance declined. However, reducing N to 50% did not affect biomass or yield compared to full rates, but improved N uptake and agronomic efficiency while reducing residual soil nitrate. The 25% N rate significantly reduced corn growth and yield. These findings suggest that applying 50% of N at planting allows flexibility to adjust remaining applications based on in-season weather. Adaptive N strategies can maintain productivity, enhance NUE, and reduce environmental risk in dryland corn systems under variable climatic conditions
CODa Re-identification (Re-ID) Dataset
Introduction
CODa Re-ID (Campus Object Dataset — Re-Identification) is a large-scale, real-world object re-identification dataset created to improve long-term robot perception and navigation in outdoor environments. It contains ≈1.04M per-frame 2D observations of 557 globally-unique static objects across 8 categories (trees, poles, bollard, informational signs, traffic signs, fire hydrants, emergency phone, and trash can) captured across multiple robot traversals on a university campus under varying lighting, weather, and viewpoint conditions.
Highlights:
Globally consistent instance IDs: each physical object is assigned a persistent global identifier tracked across all sequences.
Multi-modal annotations: per-frame 2D bounding boxes, segmentation contour, global 3D bounding boxes, and per-frame camera poses/timestamps.
Diverse conditions: captures span multiple times of day and weather (sunny, overcast, rainy, low-light/night) and a wide range of viewing distances and angles.
Reproducible pipeline: global trajectory alignment → 3D instance annotation → projection to images → automatic mask generation (SAM) → manual verification.
Evaluation ready: standardized train/val/test splits and baseline evaluation recipes (code & checkpoints included in the repo). Intended for object re-identification, object-centric SLAM, long-term localization, and persistent scene understanding research.
Content
The dataset contains (summary):
≈ 1.04M per-frame 2D observations linked to 557 globally unique 3D object instances.
Modalities: RGB images, per-frame 2D bboxes, per-frame segmentation masks (palette PNGs), projected global 3D bboxes, camera poses, timestamps, and split lists (train/val/test).
Split policy: sequences split by time/trajectory to ensure evaluation on temporally and spatially distinct holds (split files included).
Collection Method
CODa Re-ID is derived by post-processing the original CODa dataset. From the 53 categories of objects identified in CODa we re-identified only eight categories: trees, poles, bollard, informational signs, traffic signs, fire hydrants, emergency phone, and trash can.
We first align robot trajectories using LiDAR–inertial odometry with manual loop closures to obtain a single global frame. We then cluster the CODa-provided 3D bounding-box annotations along the aligned trajectories to identify persistent 3D objects. For each object we record a global 3D bounding box and observation metadata, and project these into every image frame using CODa camera intrinsics and poses. The capture sessions include repeated campus traversals, so the same object is observed under varied weather, illumination, and viewpoints.
Annotations
Annotations were created with a semi-automated pipeline:
Global 3D instance annotation and clustering across aligned trajectories to produce a unique instance_id per physical object.
Projection of global 3D boxes into all image frames to generate per-frame localization priors.
Automatic mask generation using Segment Anything (SAM) with projected boxes/points as prompts, followed by box re-fitting to mask contours.
Targeted manual verification and correction for low-confidence/flagged frames (sampled spot checks and flagged items corrected by annotators).
Each frame’s annotation is exported as a JSON record (image path, timestamp, camera pose, weather condition, instances). Example of segmentation & projected 3D annotation:
Evaluation
We provide standardized train/val/test splits and baseline results (e.g., CLOVER-based re-id baselines) plus the official training/evaluation scripts. Configuration files, example commands, and pretrained checkpoints are included in the repository to enable straightforward reproduction of reported baselines.
Dataset Organization
annotations/ — per-frame annotation(2D bounding box, segmentation contour) files organized by camera and sequence: {cam}/{sequence}/{frame}.json
3d_bbox/global/ — one JSON per object class in the global frame: {object}.json.
LICENSE — usage terms
Dataset Quality Statement
Data quality was maintained via a reproducible pipeline and a QA process that includes automated validators (missing files, empty masks, box/mask IoU checks) and manual spot checks on sampled observations. Known limitations (documented in the full report) include occasional projection error in extreme foreshortening and noisy weather labels; validation scripts are provided to re-run quality checks.

Latin American Press Review, Program 1973-14, 1973 June 21
Part I: The Latin American Press Review covers multiple significant developments in the region, beginning with the collapse of the International Coffee Agreement and its aftermath, where coffee-producing nations like Brazil and Colombia plan to establish a multinational corporation to regulate coffee prices. Excélsior delves into Watergate revelations linking conspirators to clandestine activities in Latin America, including an alleged plot to assassinate Panamanian leader Omar Torrijos. In Chile, the El Teniente copper mine strike orchestrated by the Christian Democratic Party reflects deeper divisions within the working class, with Chile Hoy attributing it to the party's strategy of sowing discord. Tensions escalate as public forces intervene, prompting President Allende to offer subsidies, but strikers demand higher wages. Meanwhile, Chile Hoy reports on a plot by Chilean Fascist Roberto Thieme to overthrow the government with support from neighboring countries. In Argentina, Juan Perón's return prompts speculation about his role in the new administration, while leftist groups continue to agitate, challenging capitalist interests. Part II: Latin American Press Review presents an interview with Brazilian exile Jean Marc von der Weid, recounting his engagement in the student movement against the Brazilian dictatorship and detailing his imprisonment and torture. Von der Weid underscores the movement's resistance against proposed university reforms backed by American foundations and highlights the dictatorship's narrow support base, primarily comprising the military and a small segment of the Brazilian upper class. He warns of foreign powers, notably the United States, supporting the dictatorship to safeguard their investments, and cautions against Brazil's gendarme role in orchestrating coups in Latin America to advance its interests. This interview concludes the Latin American Press Review, offering insightful analysis of regional events and issues on a weekly basis. Files include CSVs of the annotated transcriptions and lists of places, people, organizations, subjects, and media sources mentioned in the radio program
