Disentangling Combined Effects of Sediment Sorting, Provenance, and Chemical Weathering From a Pliocene‐Pleistocene Sedimentary Core (CSDP‐1) in the South Yellow Sea

Geochemistry, Geophysics, Geosystems, 2021
The South Yellow Sea is an important sink for sediments delivered by the Yellow and Yangtze rivers in East Asia. We conducted a high‐resolution geochemical analysis on the bulk sediments retrieved from a marine drill core (CSDP‐1) using the method of X ...

Sedimentary characterization and provenance analysis of the 2018 flooding along the Dan River, Shandong, and the hydrodynamic process reconstruction

Dizhi lixue xuebao, 2022
Sedimentary characterization of modern floods helps to reconstruct the hydrologic flood process and spot the source area of sediment erosion. It is of great referential value both to the design of flood-control works and the identification of paleo-flood

Image Provenance Analysis at Scale [PDF]

IEEE Transactions on Image Processing, 2018
Prior art has shown it is possible to estimate, through image processing and computer vision techniques, the types and parameters of transformations that have been applied to the content of individual images to obtain new images. Given a large corpus of images and a query image, an interesting further step is to retrieve the set of original images ...

Luminescence Sensitivity of Quartz From Rocks Under in situ Chemical Weathering Conditions

Frontiers in Earth Science, 2022
In provenance investigation of Quaternary sediments, quartz luminescence sensitivity (QLS) has been employed as a technique. The weathering and influence on the earliest signs of luminescence sensitivity of sedimentary quartz require more consideration ...

Provenance Analysis for Sensemaking [PDF]

IEEE Computer Graphics and Applications, 2019
The articles in this special section examine the concept of "sensemaking", which refers to how we structure the unknown so as to be able to act in it. In the context of data analysis it involves understanding the data, generating hypotheses, selecting analysis methods, creating novel solutions, and critical thinking and learning wherever needed. Due to

Detrital Mica Composition Quantitatively Indicates the Sediment Provenance along the Subei Coast to the Yangtze Estuary

Applied Sciences, 2022
The influence of large rivers on the Subei littoral plain area requires more research than the results that have been available up to now. Thus, specific diagnostic indices of detrital mica are successfully applied for the first time to identify the ...

Provenance Inference for Instagram Photos Through Device Fingerprinting

IEEE Access, 2020
Sensor pattern noise (SPN) has been extensively studied in the scientific community and has found its applications in many practical scenarios in the law-enforcement sector. However, the emergence of photo-sharing social networking sites (SNSs) poses new

Image Provenance Analysis

, 2022
AbstractThe literature of multimedia forensics is mainly dedicated to the analysis of single assets (such as sole image or video files), aiming at individually assessing their authenticity. Different from this,image provenance analysisis devoted to the joint examination of multiple assets, intending to ascertain their history of edits, by evaluating ...
