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 ...

This article examines the impact of media marketisation in China upon organisational structure and journalistic practices of Chinese news organisations. It aims to assess to what extent market factors have weakened the centralised control over local journalistic practices in the last two and a half ...

Hierarchical methods have been widely explored for object recognition, which is a
critical component of scene understanding. However, few existing works are able to
model the contextual information (e.g., objects co-occurrence) explicitly within a single
coherent framework for scene understanding. T ...

Motivated by the insufficiency of the existing quasi-identifier/sensitive-attribute (QI-SA) framework on modeling real-world privacy requirements for data publishing, we propose a novel versatile publishing scheme with which privacy requirements can be specified as an arbitrary set of privacy rules ...

Due to the distributed nature of Linked Data, many resources are referred to by more than one URI. This phenomenon, known as co-reference, increases the probability of leaving out implicit semantically related results when querying Linked Data. The probability of co-reference increases further when ...

Many applications require recovering a matrix of minimal rank within an affine constraint set, with matrix completion a notable special case. Because the problem is NP-hard in general, it is common to replace the matrix rank with the nuclear norm, which acts as a convenient convex surrogate. While e ...

The manifold of Symmetric Positive Definite (SPD) matrices has been successfully used for data representation in image set classification. By endowing the SPD manifold with LogEuclidean Metric, existing methods typically work on vector-forms of SPD matrix logarithms. This however not only inevitably ...

We propose a new data-driven procedure for optimal selection
of tuning parameters in dynamic clustering algorithms,
using the notion of stability probe. Due to the shape of the
stability probe dynamics, we refer to the new clustering stability
procedure as Downhill Riding (DR). We study final
s ...

In an era of ubiquitous large-scale streaming data, the availability
of data far exceeds the capacity of expert human analysts. In many
settings, such data is either discarded or stored unprocessed in data
centers. This paper proposes a method of online data thinning, in
which large-scale stream ...
