The structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six continents, and found that urban soils are important hotspots for soil bacterial, p ...

Soil contamination is one of the main threats to ecosystem health and sustainability. Yet little is known about the extent to which soil contaminants differ between urban greenspaces and natural ecosystems. Here we show that urban greenspaces and adjacent natural areas (i.e., natural/semi-natural ec ...

Mechanical shields can effectively alleviate the problems of low pesticide utilization and severe environmental pollution. This manuscript uses a computational fluid dynamics (CFD) method to investigate the anti-drift mechanism of mechanical shields, study the airflow forms around them, and establis ...

In recent years, the Rotating electromagnetic Field Eddy Current (RFEC) testing technique has attracted widespread attention due to its various advantages for the inspection of tubular structures. However, most of the related work were focused on the detection of inner wall defects on metal pipes us ...

Multi-label learning has attracted much attention during the past few years. Many multilabel learning approaches have been developed, mostly working with surrogate loss functions since multi-label loss functions are usually difficult to optimize directly owing to non-convexity and discontinuity. Tho ...

The basis assumption “training and test data drawn from the same distribution” is often violated. We propose one common solution to cover various scenarios of learning under “different but related distributions” in a single framework. Examples include (a) sample selection bias (b) transfer learning ...

Merchants selling products on the Web often ask their customers to share their opinions and hands-on experiences on products they have
purchased. As e-commerce is becoming more and more popular, the number of customer reviews a product receives grows rapidly. This
makes it difficult for a potential ...

Codebook-based representations are widely employed in the classification of complex objects such as images and documents. Most
previous codebook-based methods construct a single codebook via clustering that maps a bag of low-level features into a fixed-length
histogram that describes the distributio ...
