The Yangtze River dolphin or baiji ( Lipotes vexillifer ), an obligate freshwater odontocete known only from the middle-lower system and neighbouring Qiantang in eastern China, has long been recognized as one of world's rarest most threatened mammal species. status not investigated since late 1990s, when surviving population was estimated to be low 13 individuals. An intensive six-week multi-vessel visual acoustic survey carried out November–December 2006, covering entire historical range...

Asphalt roads are the basic component of a land transportation system, and quality asphalt will decrease during use stage because aging deterioration road surface. In end, some pavement distresses may appear on surface, such as most common potholes cracks. order to improve efficiency inspection, currently new forms remote sensing data without destructive effect widely used detect distresses, digital images, light detection ranging, radar. Multispectral imagery presenting spatial spectral...

Water clarity is a well-established first-order indicator of water quality and has been used globally by regulators in their monitoring management programs. Assessments lakes over large temporal spatial scales, however, are rare, limiting our understanding its variability the driven forces. In this study, we developed validated robust Secchi disk depth (ZSD) algorithm for across China based on two color parameters, namely Forel-Ule Index (FUI) hue angle α, retrieved from MODIS data. The ZSD...

Road pavement damage affects driving comfort markedly, threatens safety, and may even cause traffic accidents. The management department conventionally captures information mainly using manual vehicle-mounted equipment, which is not conducive to the detection of large-scale road distress. Street-view images can provide full-view urban roads where data updated regularly by navigation map service companies, making it possible rapidly detect in areas. This paper presents a new approach that...

The wetland classification from remotely sensed data is usually difficult due to the extensive seasonal vegetation dynamics and hydrological fluctuation. This study presents a random forest approach for retrieval of landcover in arid regions by fusing Pléiade-1B with multi-date Landsat-8 data. segmentation multispectral image was performed based on an object-oriented approach, geometric spectral features were extracted segmented objects. normalized difference index (NDVI) series also...

With the rapid growth in availability of data and computational technologies, multiple machine learning frameworks have been proposed for forecasting air pollution. However, feasibility these complex approaches has seldom verified developing countries, which generally suffer from heavy To forecast PM2.5 concentrations over different time intervals, we implemented three approaches: additive regression trees (MART), a deep feedforward neural network (DFNN) new hybrid model based on long...

Abstract Water colour is the result of its constituents and their interactions with solar irradiance; this forms basis for water quality monitoring using optical remote sensing data. The Forel-Ule Index (FUI) a useful comprehensive indicator to show variability change in both inland waters oceans. In recent decades, lakes around world have experienced dramatic changes under pressure from climate anthropogenic activities. However, acquiring consistent products global has been challenge. paper...

Genetic changes have occurred in the genomes of prevalent African swine fever viruses (ASFVs) field China, which may change their antigenic properties and result immune escape. There is usually poor cross-protection between heterogonous isolates, and, therefore, it important to test live attenuated ASFV vaccines against current isolates. In this study, we evaluated protective efficacy vaccine candidate HLJ/18-7GD emerging provided protection a highly virulent variant lower lethal isolate,...

The collapse of buildings caused by earthquakes can lead to a large loss life and property. Rapid assessment building damage with remote sensing image data support emergency rescues. However, current studies indicate that only limited sample set usually be obtained from images immediately following an earthquake. Consequently, the difficulty in preparing sufficient training samples constrains generalization model identification earthquake-damaged buildings. To produce deep learning network...

African swine fever (ASF) is an acute, hemorrhagic, and severe infectious disease caused by the ASF virus (ASFV). ASFV has evolved multiple strategies to escape host antiviral immune responses. Here, we reported that pB318L, a trans-geranylgeranyl-diphosphate synthase, reduced expression of type I interferon (IFN-I) IFN-stimulated genes (ISGs). Mechanically, pB318L not only interacted with STING reduce translocation from endoplasmic reticulum Golgi apparatus but also IFN receptors...

Remote sensing image segmentation with samples imbalance is always one of the most important issues. Typically, a high-resolution remote has characteristics high spatial resolution and low spectral resolution, complex large-scale land covers, small class differences for some vague foreground, imbalanced distribution samples. However, traditional machine learning algorithms have limitations in deep feature extraction dealing sample issue. In paper, we proposed an improved full-convolution...
