Deep Learning-Based Classification and Semantic Segmentation of Lung Tuberculosis Lesions in Chest X-ray Images Open
We present a deep learning (DL) network-based approach for detecting and semantically segmenting two specific types of tuberculosis (TB) lesions in chest X-ray (CXR) images. In the proposed method, we use a basic U-Net model and its enhanc…

Formation of broad-valley morphology triggered by uplift of Yulong-Haba Snow Mountains in the First Bend reaches of the Jinsha River, upper Yangtze River, SE Tibet Plateau Open
The southeast Tibetan Plateau (SETP) was marked with strong neotectonics due to the collision of Asia-Europe plate and Indian plate. However, different from the SETP morphology characterized by high mountains and deep-narrow valleys, broad…

Grain size distribution of bulk-sample, detrital zircons and rutiles from the Yangtze River: implications for the sediment routing Open
Changes in the grain size distribution of river sediment have environmental, ecological and social implications. This study investigated the variation of the grain size of bulk samples, detrital zircons and rutiles from the mainstream and …

Residual electron spin resonance signals of quartz from the 2018 Baige dammed lake in Tibet: Implications for the identification of sediment layers caused by megafloods Open
Residual doses may cause overestimation of electron spin resonance (ESR) ages for fluvial sediments. However, ESR residual doses in outburst megaflood sediments have rarely been evaluated. The Jinsha River, situated in the southeastern Tib…

Heavy Mineral Assemblage Variation in Late Cenozoic Sediments from the Middle Yangtze River Basin: Insights into Basin Sediment Provenance and Evolution of the Three Gorges Valley Open
The Three Gorges valley is one of the two key capture points of the evolution of the Yangtze River, yet the formation of this valley—from the pre-Miocene to the late Pleistocene—remains uncertain. The Jianghan Basin, a late Mesozoic–Cenozo…

Electron Spin Resonance (ESR) Signal Intensity of Quartz E<sub>1</sub>′ Centre and Its Potential Use in Fluvial Sediments Provenance Tracing Open
To assess if the heat-treated E1′ centre in quartz is suitable for fluvial sediment provenance tracing, eight granitic samples from sediments and their source rocks with distinct geological ages and origins were collected for electron spin…

Holocene OSL Chronology of Flu-Lacustrine Sediments in Yangtze River Basin, Wuhan Area, China Open
Wuhan area located middle Yangtze River Basin, is dominated by East Asian Monsoon. Widely developed Holocene flu-lacustrine sediments are ideal materials for the reconstruction of paleoclimate change and geo-environment evolution, for whic…

Application of long time artificial optical bleaching of the E<sub>1</sub>’ centre to sediment ESR dating Open
Three quartz samples extracted from different origins were collected for ESR evaluation to appreciate the optical bleaching characteristics of the E1’ centre in a long time scale. After exposure of about 400 hours to artificial sunlight, t…
