This data article introduces a structured pavement surface image dataset developed to advance research in automated pavement condition assessment and data-driven road infrastructure monitoring. The dataset comprises three distinct pavement condition categories: (i) alligator cracking, (ii) edge-breaking distress, and (iii) undamaged (intact) pavement surfaces, each representing a prevalent form of pavement deterioration or intact condition typically observed in flexible pavements. The dataset consists of 12,000 raw images (4000 per class) collected under real-world conditions. These images represent the primary scientific contribution of the dataset. All images were standardized through resizing and normalization, and the dataset was partitioned into training, validation, and testing subsets to ensure reproducibility and consistency in data-driven experiments. Pavement images were collected from selected segments of National Highway N6 in Pabna District, Bangladesh, under natural daylight conditions using a smartphone camera during field surveys. Image acquisition was conducted following standard safety practices without disrupting traffic flow. All images were manually reviewed and labelled to ensure annotation accuracy. This dataset is intended to support research on automated pavement crack detection and classification, benchmarking of computer vision and deep learning models, and the development of lightweight and edge-deployable inspection systems.
这篇数据文章介绍了一个结构化的路面表面图像数据集,旨在推进自动路面状况评估和数据驱动的道路基础设施监测的研究。该数据集包括三种不同的路面状况类别:(i)鳄鱼裂缝,(ii)边缘破损,以及(iii)未损坏(完整)的路面,每一种都代表了一种常见的路面恶化形式或通常在柔性路面中观察到的完好状况。该数据集由在真实世界条件下收集的12,000张原始图像(每个类4000张)组成。这些图像代表了数据集的主要科学贡献。通过调整大小和归一化对所有图像进行标准化,并将数据集划分为训练、验证和测试子集,以确保数据驱动实验的可重复性和一致性。在实地调查期间,使用智能手机相机在自然日光条件下收集了孟加拉国Pabna地区N6国道选定路段的路面图像。图像采集是在不干扰交通流量的情况下按照标准安全措施进行的。所有的图像都是手动审查和标记,以确保注释的准确性。该数据集旨在支持自动路面裂缝检测和分类的研究,计算机视觉和深度学习模型的基准测试,以及轻量级和边缘可部署检测系统的开发。

The Chinese giant salamander is classified as a Class II protected species in China and is recognized as critically endangered by the International Union for Conservation of Nature (IUCN). Due to their unique behavioral patterns, wild Chinese giant salamanders are primarily nocturnal and inhabit areas characterized by complex terrain, which results in limited detection coverage and significant challenges in observation. Consequently, images of wild Chinese giant salamanders are exceedingly rare, and the scarcity of existing data impedes the advancement and application of deep learning-based object detection models. This study constructs and releases a specialized dataset for Chinese giant salamanders, comprising 1386 images and a total of 1397 annotated bounding boxes. All images represent diverse field scenarios and are meticulously annotated in accordance with YOLO (You Only Look Once) labeling specifications. Annotation files are provided in both PASCAL VOC (Visual Object Classes) and COCO (Common Objects in Context) formats to ensure compatibility with leading detection frameworks, including YOLO v8 and YOLO v11. This dataset aims to offer high-quality, multi-scenario annotated data for research in computer vision and conservation biology, facilitating the training and evaluation of models for intelligent monitoring and species conservation of the Chinese giant salamander, thereby promoting the development of visual recognition technologies for endangered species.
中国大鲵在中国被列为二级保护物种,被国际自然保护联盟(IUCN)认定为极度濒危物种。由于其独特的行为模式,野生大鲵以夜间活动为主,居住在地形复杂的地区,这导致了探测覆盖率的限制和观测的重大挑战。因此,野生大鲵的图像非常罕见,现有数据的稀缺性阻碍了基于深度学习的目标检测模型的进步和应用。本研究构建并发布了中国大鲵的专业数据集,包含1386张图像和1397个带注释的边界框。所有图像代表不同的现场场景,并按照YOLO(你只看一次)标签规范精心注释。注释文件以PASCAL VOC(可视化对象类)和COCO(上下文中的公共对象)两种格式提供,以确保与领先的检测框架兼容,包括YOLO v8和YOLO v11。该数据集旨在为计算机视觉和保护生物学研究提供高质量、多场景的标注数据,促进大鲵智能监测和物种保护模型的训练和评估,从而促进濒危物种视觉识别技术的发展。

Integrated Mangrove Aquaculture (IMA) and Sustainable Aquaculture in Mangrove Ecosystem Fisheries (SAIME) are key activities undertaken across coastal regions globally to meet growing demand for brackish-water aquaculture products through sustainable practices. An in-depth biomonitoring study was conducted to map the ecological health of IMA and non-IMA aquaculture ponds in the surrounding region of the Indian Sundarbans mangroves located along the northeast coast of Bay of Bengal. Surface water samples were collected from six aquaculture ponds, four IMA (IMA_C1, IMA_C3, IMA_DB1, and IMA_DB4) and two non-IMA (C6_NM and DB5_NM) in the month of October 2022, for characterizing niche-specific biological communities using the environmental DNA (eDNA) approach. During sampling, in-situ environmental parameters were recorded. Mangrove litter-derived phenolics (tannic and gallic acids) and dissolved nutrients were estimated using a UV–Vis spectrophotometer, while dissolved organic carbon (DOC) was measured with the elemental analyzer. Metal and metalloid concentrations were determined by inductively coupled plasma mass spectrometry approach (ICP–MS). IMA ponds showed ideal conditions for shrimp aquaculture, with pH ranging from 7.913 to 8.633 and dissolved oxygen (DO) between 5.32 and 6.03 mg/L, indicating no hypoxic conditions despite higher concentrations of phenolics. High-throughput sequencing (HTS) based on Oxford Nanopore Technologies (ONT) sequencing chemistry was undertaken on the MinION platform, revealing the predominance of Proteobacteria among prokaryotes and Bacillariophyta as well as Chlorophyta among eukaryotes from extracted eDNA in each studied pond. Additionally, members of the family Cyprinidae were also detected, reflecting the biodiversity of fish population in these ponds. Functional gene profiling indicated signatures associated with nitrogen, phosphorus, sulphur, potassium and iron acquisition and metabolism, along with pathways related to aromatic compound degradation. Overall, dissolved nutrients, dissolved organic carbon (DOC), metal and metalloid ion concentrations as well as structure and functional profiles of biological communities provide a comprehensive basis for evaluating the ecological health of aquaculture ponds. This study generates important baseline information for long-term monitoring and represents the first eDNA-based high-throughput sequencing assessment of IMA and non-IMA aquaculture ponds from surface water in close proximity to the Sundarbans mangrove.
红树林综合水产养殖(IMA)和红树林生态系统渔业可持续水产养殖(SAIME)是全球沿海地区开展的关键活动,旨在通过可持续做法满足对咸淡水水产养殖产品日益增长的需求。对位于孟加拉湾东北海岸的印度孙德尔本斯红树林周边地区IMA和非IMA养殖池塘的生态健康状况进行了深入的生物监测研究。采用环境DNA (environmental DNA, eDNA)方法,于2022年10月采集了6个养殖池塘的地表水样本,其中4个IMA池塘(IMA_C1、IMA_C3、IMA_DB1和IMA_DB4)和2个非IMA池塘(C6_NM和DB5_NM),用于表征生态位特异性生物群落。在采样过程中,记录了现场环境参数。利用紫外-可见分光光度计估算红树林凋落物衍生的酚类物质(单宁酸和没食子酸)和溶解营养物质,并用元素分析仪测量溶解有机碳(DOC)。采用电感耦合等离子体质谱法(ICP-MS)测定金属和类金属浓度。IMA池塘的pH值在7.913 ~ 8.633之间,溶解氧(DO)在5.32 ~ 6.03 mg/L之间,表明尽管酚类物质浓度较高,但没有缺氧条件,是对虾养殖的理想条件。在MinION平台上进行基于Oxford Nanopore Technologies (ONT)测序化学的高通量测序(HTS),从每个研究池塘提取的eDNA中发现,原核生物中以Proteobacteria为主,硅藻中以Bacillariophyta为主,真核生物中以绿藻为主。此外,还检测到鲤科的成员,反映了这些池塘鱼类种群的多样性。功能基因图谱显示了与氮、磷、硫、钾和铁的获取和代谢相关的特征,以及与芳香族化合物降解相关的途径。总体而言,溶解营养物质、溶解有机碳(DOC)、金属和类金属离子浓度以及生物群落结构和功能特征为评价水产养殖池塘生态健康提供了综合依据。该研究为长期监测提供了重要的基线信息,并首次对孙德尔本斯红树林附近地表水中的IMA和非IMA水产养殖池塘进行了基于edna的高通量测序评估。

A comprehensive multimodal MRI and EEG-TMS dataset on the impact of parietal cortex inhibition on decision-making under ambiguity 一个综合的多模态MRI和EEG-TMS数据集研究了模糊情况下顶叶皮层抑制对决策的影响
IF 1.4 Q3 MULTIDISCIPLINARY SCIENCES Pub Date : 2026-04-01 Epub Date: 2026-02-02 DOI: 10.1016/j.dib.2026.112535

In daily life, we often face decisions where potential outcomes are unclear, creating uncertainty. The complete or partial lack of knowledge regarding outcome probabilities—referred to as ambiguity—poses significant challenges for individuals. While recent studies have linked ambiguity in decision-making to neural activity in the parietal cortex, the precise role of this region and its interactions with other brain areas remain poorly understood.
Here, we present a comprehensive dataset on human decision-making under conditions of risk and ambiguity. The dataset includes two experimental sessions. The first one corresponds to the MRI setting, which includes structural MRI (T1- and T2-weighted images, n = 52), diffusion-weighted imaging (n = 45), and task-based functional MRI (n = 38). The second session corresponds to the EEG setting combined with inhibitory transcranial magnetic stimulation (TMS), targeting two parietal regions and the vertex (n = 24). TMS targets were defined from group-level fMRI activations obtained in the first session and then transformed to individual anatomy. Ten participants completed both fMRI and EEG-TMS recordings.
This dataset, partially analyzed in previous work, now includes newly acquired and previously unexamined data—such as diffusion-weighted imaging, T2-weighted images—and is fully organized according to the Brain Imaging Data Structure (BIDS) standard. It provides valuable opportunities to investigate the neurobiological decision-making mechanisms under ambiguity, focusing on the parietal cortex.
在日常生活中,我们经常面临潜在结果不明确的决定,从而产生不确定性。完全或部分缺乏关于结果概率的知识——被称为模糊性——给个人带来了重大挑战。虽然最近的研究将决策的模糊性与顶叶皮层的神经活动联系起来,但该区域的确切作用及其与其他大脑区域的相互作用仍然知之甚少。在这里,我们提出了一个关于风险和模糊条件下人类决策的综合数据集。数据集包括两个实验环节。第一个与MRI设置相对应,包括结构MRI (T1和t2加权图像,n = 52),弥散加权成像(n = 45)和基于任务的功能MRI (n = 38)。第二阶段对应于脑电图设置结合抑制性经颅磁刺激(TMS),针对两个顶叶区域和顶点(n = 24)。经颅磁刺激靶是根据第一阶段获得的群体水平的fMRI激活来定义的,然后转化为个体解剖。10名参与者同时完成了fMRI和EEG-TMS记录。该数据集在之前的工作中进行了部分分析,现在包括新获得的和以前未检查的数据,如弥散加权成像、t2加权图像,并根据脑成像数据结构(BIDS)标准进行了完全组织。它为研究模糊情况下的神经生物学决策机制提供了宝贵的机会,重点是顶叶皮层。

The complete mitochondrial genome and phylogenetic analysis of the polychaete Diopatra sp. (Annelida: Onuphidae) 多毛动物Diopatra sp.线粒体全基因组及系统发育分析(环节动物:轮足动物科)
IF 1.4 Q3 MULTIDISCIPLINARY SCIENCES Pub Date : 2026-04-01 Epub Date: 2026-01-28 DOI: 10.1016/j.dib.2026.112526

The polychaete genus Diopatra is widely distributed in tropical and subtropical coasts and plays key ecological roles as an ecosystem engineer. Despite >65 recognized species, its taxonomy remains unresolved due to extensive cryptic speciation and limited molecular data. In this study, we sequenced and annotated the complete mitochondrial genome of Diopatra sp. collected from Incheon, South Korea. The mitogenome was 14,985 base pairs in length and contained 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes (rrnS and rrnL), consistent with typical metazoan organization. This mitogenome provides a genetic reference that supports comparative mitogenomic and phylogenetic analyses, as well as the resolution of cryptic diversity and accurate taxonomic assignment in environmental DNA (eDNA)-based biodiversity assessments. Phylogenetic analysis based on concatenated PCG sequences from 37 polychaete mitogenomes representing six families placed Diopatra sp. in a well-supported clade with Diopatra cuprea and Hyalinoecia robusta (Onuphidae) within the subclass Errantia. These findings reinforce the monophyly of Diopatra within Errantia and provide valuable genetic information for resolving the cryptic diversity, phylogenetic relationships, and evolutionary history of polychaetes.
多毛类Diopatra广泛分布于热带和亚热带海岸,在生态系统中起着重要的工程作用。尽管有65种已知物种,但由于广泛的隐种形成和有限的分子数据,其分类仍未解决。在这项研究中,我们对来自韩国仁川的Diopatra sp.的线粒体全基因组进行了测序和注释。有丝分裂基因组全长14985个碱基对,包含13个蛋白质编码基因(PCGs)、22个转移RNA (tRNA)基因和2个核糖体RNA (rRNA)基因(rrnS和rrnL),符合典型的后生动物组织。该有丝分裂基因组提供了一个遗传参考,支持比较有丝分裂基因组学和系统发育分析,以及在基于环境DNA (eDNA)的生物多样性评估中解决隐多样性和准确的分类分配。基于代表6个科的37种多毛目有丝分裂基因组的PCG序列序列的系统发育分析表明,Diopatra sp.与Diopatra cuprea和Hyalinoecia robusta (Onuphidae)在Errantia亚纲中属于一个支持良好的分支。这些发现强化了亚种中Diopatra的单系性,并为解决多毛类的隐性多样性、系统发育关系和进化史提供了有价值的遗传信息。

Two-year daily precipitation stable isotope dataset (δ18O and δ2H) from a continental station in NW Croatia 克罗地亚西北部大陆站两年日降水稳定同位素数据集(δ18O和δ2H)
IF 1.4 Q3 MULTIDISCIPLINARY SCIENCES Pub Date : 2026-04-01 Epub Date: 2026-01-29 DOI: 10.1016/j.dib.2026.112509

The stable water isotopic composition (δ18O and δ2H) of daily precipitation from north-western Croatia (near Samobor town) is presented. The dataset includes a total of 288 precipitation samples collected from December 2022 to November 2024. The collection period roughly covered a 24-hour cycle, starting predominantly early in the morning. Stable hydrogen and oxygen isotope analyses of the samples were carried out using a Picarro L2130-i Isotope analyzer, with a precision of 1 ‰ for δ2H and 0.2 ‰ for δ18O. The raw isotopic data of the precipitation samples are presented in δ-notation (‰) normalized to the international standard VSMOW (Vienna Standard Mean Ocean Water). Additionally, the d-excess values for each sample and the Local meteoric water line (LMWL) were calculated. Presented data were used to investigate the main drivers of stable isotope variability in Croatia and were published in the research article entitled “Assessing the influence of climatic parameters and moisture sources on precipitation isotope composition from central Croatia: Insights from a two-year long daily-resolved dataset“.

Industrial hemp cultivation is expanding and requires reliable monitoring for legal compliance and agricultural management. This paper presents a standardized UAV-based multisensor framework designed for Cannabis sativa L. It integrates RGB, multispectral, and thermal imaging as core modules, with hyperspectral and LiDAR as optional extensions. The framework sets protocols for sensor integration, flight planning, field measurements, and annotation, ensuring datasets that meet EU altitude limits (≤120 m AGL). Multi-altitude and multi-time-of-day acquisitions are proposed to capture spatial and diurnal variability. These data improve model robustness for phenotyping, stress detection, and THC compliance verification. Potential applications include precision agriculture, breeding, regulatory monitoring, environmental assessment, and illicit crop detection. Open-access datasets generated through this framework will support reproducibility, machine learning development, and collaboration among researchers, farmers, and regulators.

The ConcreteCARB dataset provides a comprehensive repository of 903 high-resolution images of concrete surfaces evaluated using the phenolphthalein test for carbonation detection. This data was collected under controlled laboratory conditions and aims to support artificial intelligence applications in civil engineering, especially in structural health monitoring tasks. The images are systematically organized into two distinct classes: “Carbonated Samples” and “No Carbonation Presence,” enabling binary classification approaches. All samples were manually tested, split, and visually labelled by expert engineers to ensure reliable ground-truth classification, in accordance with standardized procedures. The dataset includes images of concrete prism elements fabricated with varying mix designs, incorporating different water-cement ratios and additives, such as industrial silica waste and natural admixtures derived from Opuntia ficus-indica. The specimens were subjected to natural atmospheric carbonation conditions for 180 days, and their carbonation fronts were revealed by phenolphthalein staining. The samples were then split manually with a chisel and hammer, and photographic documentation was performed with a Samsung SM-S901U1 smartphone using predefined settings to ensure consistency and quality across the dataset. ConcreteCARB is intended for researchers, engineers, and data scientists working on machine learning, deep learning, and computer vision solutions for concrete diagnostics. It provides valuable training and benchmarking data for the development of automated detection, classification, and segmentation models for carbonation damage assessment. Furthermore, the dataset can serve as a foundational tool for cross-comparative studies on the efficacy of AI techniques in materials degradation analysis. The openly accessible nature of the dataset through a public repository supports reproducibility and encourages the extension of AI applications in concrete durability and sustainability studies.
ConcreteCARB数据集提供了903张混凝土表面高分辨率图像的综合存储库,使用酚酞测试进行碳化检测。这些数据是在受控的实验室条件下收集的,旨在支持人工智能在土木工程中的应用,特别是在结构健康监测任务中。这些图像被系统地组织成两个不同的类别:“碳酸化样本”和“无碳酸化存在”,这使得二元分类方法成为可能。所有样品都由专家工程师手工测试、分离和视觉标记,以确保根据标准化程序进行可靠的真实分类。该数据集包括混凝土棱柱体的图像,这些棱柱体采用不同的混合设计,采用不同的水灰比和添加剂,如工业二氧化硅废料和源自无花果树的天然外加剂。将样品置于自然大气碳酸化条件下180 d,通过酚酞染色显示其碳酸化锋。然后用凿子和锤子手动分割样本,并使用三星SM-S901U1智能手机进行摄影记录,使用预定义设置确保数据集的一致性和质量。ConcreteCARB适用于研究机器学习、深度学习和混凝土诊断计算机视觉解决方案的研究人员、工程师和数据科学家。它为开发用于碳酸化损害评估的自动检测、分类和分割模型提供了有价值的训练和基准数据。此外,该数据集可以作为人工智能技术在材料降解分析中的功效交叉比较研究的基础工具。通过公共存储库开放访问数据集的特性支持再现性,并鼓励人工智能应用在混凝土耐久性和可持续性研究中的扩展。

Measurement data from full-scale fire experiments of battery electric vehicles and internal combustion engine vehicles 纯电动汽车和内燃机汽车全尺寸着火实验测量数据
IF 1.4 Q3 MULTIDISCIPLINARY SCIENCES Pub Date : 2026-04-01 Epub Date: 2026-01-16 DOI: 10.1016/j.dib.2026.112471

Over time, the burning behaviour of passenger vehicles has been influenced by continuous advancements in vehicle design, including changes in materials, manufacturing processes, and the integration of modern lithium-ion battery powertrains. Fire protection engineers, first responders, and other safety professionals currently lack sufficient data to determine whether existing fire protection system designs and firefighting practices effectively mitigate the burning behaviour of modern vehicle fires or to adapt these approaches to any measurable changes in fire dynamics. Eighteen full-scale vehicle fire experiments were conducted in a laboratory environment to obtain a novel data set describing the fire size, thermal hazards, and evolved smoke and particulate species resulting from vehicle fires. Vehicle mass, gas temperature, heat flux, sorbent tube, Fourier-transform infrared spectrometer, and suppression waterflow data are provided in tabular format. Eight vehicle models across six manufacturers were selected based on the most popular battery electric and gasoline powered compact and mid-sized recently sold in North America at the time of writing. Experiments consisted of nine free-burn experiments wherein the gasoline vehicles were ignited in the engine compartment and the electric vehicle battery packs were induced into thermal runaway; these fires progressed unabated until the occurrence of natural flame extinction. Another four experiments simulated electric vehicle fire suppression using ordinary water and traditional vehicle fire suppression techniques. In one additional experiment, an encapsulator firefighting agent was added to the water. The final four experiments consisted of deploying fire blankets over the burning vehicles a single strategy or in combination with water simultaneously applied from beneath. There are many potential uses of this data, but primary uses are expected to include revision of design criteria and guidance within the fire protection engineering community, strategic and tactical decision aids for vehicle fire incident operations, validation of existing (and development of new) fire behavior models, and guidance to vehicle manufacturers for improved fire safety design.
随着时间的推移,乘用车的燃烧行为受到车辆设计不断进步的影响,包括材料、制造工艺的变化以及现代锂离子电池动力系统的集成。消防工程师、急救人员和其他安全专业人员目前缺乏足够的数据来确定现有的消防系统设计和消防实践是否有效地减轻了现代车辆火灾的燃烧行为,或者使这些方法适应火灾动力学的任何可测量变化。在实验室环境中进行了18次全尺寸车辆火灾实验,以获得描述火灾规模、热危害以及车辆火灾产生的烟雾和颗粒种类的新数据集。车辆质量、气体温度、热流、吸附管、傅里叶变换红外光谱仪、抑制水流数据以表格形式提供。在撰写本文时,根据最近在北美销售的最受欢迎的电池电动和汽油动力紧凑型和中型车,选择了6家制造商的8款车型。实验包括9个自由燃烧实验,分别在发动机舱内点燃汽油车,诱导电动汽车电池组热失控;这些大火不断发展,直到火焰自然熄灭。另外四个实验分别采用普通水和传统车辆灭火技术模拟电动汽车灭火。在另一项实验中,向水中加入了一种封装式灭火剂。最后四个实验包括在燃烧的车辆上铺上防火毯,一种策略,或者与从下面同时浇水相结合。这些数据有许多潜在的用途,但主要用途预计包括修订设计标准和指导消防工程社区,为车辆火灾事故操作提供战略和战术决策辅助,验证现有(和开发新的)火灾行为模型,并指导车辆制造商改进消防安全设计。
