My research work is centered around clustering, the most basic form of unsupervised learning. It extends to several closely related areas including: probabilistic mixture models, manifold leaning and dimension reduction, low rank approximation, maximum margin clustering and semi-supervised learning. An important theme of my work is to scale up the currently existing, but computationally demandi...
Key authentication is very important in secret communications and data security. Lee et al. proposed a new public key authentication scheme for cryptosystems based on discrete logarithms in 2003. Recently, Zhang et al. pointed out that Lee et al.’s scheme was not secure and proposed an improvement on it. However, in this paper, we will demonstrate that a dishonest user can forge the public key ...
Technology, describe how taking an integrated approach to energy performance early in the design phase can deliver significant improvements in refinery energy efficiency. E nergy is the second single largest component of variable refinery operating expense, representing some 40-50% of total operating costs, excluding the cost of purchasing raw crude. Fuel and power consumption is also directly ...
T wo recent reports by Zhang et al published in Nov (2011) and our group (Anand & Kai, 2012; published online in Dec 2011) have suggested a role for the conserved Tudor domain protein encoded by qin as a component of piRNA pathway. Both studies agree that qin plays a role in the piRNA pathway and is required to repress reteroelements but differ in some aspects of their conclusions about qin fun...
The leafhopper genus Macrosteles Fieber in China comprises 25 species including ten new species: Macrosteles brochus Zhang & Lu, M. brunneus Zhang & Lu, M. choui Zhang & Lu, M. ehensis Zhang & Lu, M. gracilis Zhang & Lu, M. falcatus Zhang & Lu, M. haperatus Zhang & Lu, M. nabiae Kwon, M. parastriifrons Zhang & Lu and M. spinosus Kwon. Five species are newly recorded from China, including M. abl...
The pine aphid Cinara pinitabulaeformis Zhang et Zhang is the main pine pest in China, it causes pine needles to produce dense dew (honeydew) which can lead to sooty mold (black filamentous saprophytic ascomycetes). Although common chemical and physical strategies are used to prevent the disease caused by C. pinitabulaeformis Zhang et Zhang, new strategies based on biological and/or genetic app...

Intervals are related to the representation of uncertainty. In this sense, we introduce an integral of Gould type for an interval-valued multifunction relative to an interval-valued set multifunction, with respect to Guo and Zhang order relation. Classicaland specific properties of this new type of integral are established and several examples and applications from multicriteria decision making...
