Panzhihua City is a typical agricultural-forestry-pastoral and ecologically sensitive city in China. It also an important ecological defense the upper Yangtze River. has abundant mineral resources, including vanadium, titanium, water supplies. However, environmental problems emerge due to excessive development of mining, agriculture, animal husbandry, other non-natural urban economies. Therefore, scientific understanding spatio-temporal changes eco-environment critical for protection,...
Lakes over the Qinghai-Tibet Plateau (TP) have large quantities and areas. As an important component of fragile plateau ecosystems, these lakes attracted increasing attention. However, owing to limitations technology methods, changes in smaller on TP received less In this study, we used Google Earth Engine (GEE) with Analysis Ready Data (ARD) preparation framework obtain preprocessed Sentinel-1 data covering plateau. The D-LinkNet was introduced achieve lake extraction, dataset completed...
Abstract With the drastic change in global climate, wide distribution of natural lakes over Qinghai-Tibet Plateau (TP) has attracted extensive attention due to their high climate sensitivity. In this paper, we investigated dynamics Paiku Co, largest inland lake Qomolangma Natural Reserve, with associated response past three decades. The methods used contain water index method, spatial and temporal fusion model, statistical mono-window algorithm, multi-variable linear regression. Lake area...
Glacial lakes are important freshwater resources in southern Tibet. However, glacial lake outburst floods have significantly jeopardized the safety of local residents. To better understand changes response to climate change, it is necessary conduct a long-term evaluation on areal dynamics lakes, assisted with observations. Here, we propose an innovative method classification and stacking extraction accurately delineate southwestern Tibet from 1990 2020. Based Landsat images meteorological...
The Yellow River Basin in China has the world's most serious soil erosion problem. Sichuan Province (YRS), as upper reaches of River, and its water conservation (WC) capacity greatly affects ecological environment downstream basin. In recent years, YRS received more attention, numerous policies have been developed to improve local WC. However, there is a vacancy long-term research WC due lack in-situ data. This study quantitatively evaluated from 2001 2020 through Google Earth Engine (GEE)...
Abstract Purpose To introduce, implement, and assess an iterative modification to the active deformational image segmentation method as applied cervical cancer tumors. Materials Methods A comparison by Jaccard similarity (J S ) between this manual was performed on tumors of various sizes across preradiation, 3 weeks postradiation, 6 postradiation using a General Linear Mixed Model 121 studies from 52 patients with Stage IIB‐IV cancers. Results The deformable produced promising levels...
Community detection is helpful to understand useful information in real‐world networks by uncovering their natural structures. In this paper, we propose a simple but effective community algorithm, called ACC, which needs no heuristic search has near‐linear time complexity. ACC defines novel similarity different from most common definitions considering not only neighbors of two adjacent nodes also mutual exclusive degree. According similarity, groups together obtain the initial structure...
Finding clusters in datasets with different distributions and sizes is challenging when are of widely various shapes, sizes, densities. Based on a similar-to-multiple-point clustering strategy, novel simple algorithm named MulSim presented to address these issues this paper. first defines new distance which can automatically adapt densities clustering. Then, the groups two points together if only one point similar another its neighbors. Our comprehensive experiments both multi-dimensional...
Detecting the natural communities in a real-world network can uncover its underlying structure and potential function. In this paper, novel community algorithm SUM is introduced. The fundamental idea of that node with relatively low degree stays faithful to community, because it only has links nodes one while high not within but also outside may cause confusion when detecting communities. Based on idea, detects by suspecting maximum their neighbors relying mainly simultaneously. elegantly...
Purpose: To investigate the effects of x‐ray exposure parameters and added beam filtration on patient dose image quality for optimization chest computed radiography (CR). Method Materials: A phantom (CardinalHealth Model 76‐211) was used to simulate a standard size. achieve small or large size, one sheet 25‐mm acrylic removed added, respectively. Pre‐ post‐patient spectra were measured using CdTe spectrometer at various conditions filters. kVp stations 80, 100, 120 selected. An Al plate 0,...
