On Sep. 12, 2006, Prof. chen yiyu, President of NSFC met with Dr. Gustavo Chapela, President of Consejo Nacional de Cienciay Tecnologia （CONACYT）of Mexico. At the invitation of Chinese Ministry of Science and Technology, the delegation visited China on a mission of exploring channels to promote bilateral science and technology cooperation with relevant science and technology administrative agencies between China and Mexico. The meeting between top administrators of the two sides is the second time of its kind since the visit of the ex-President of CONACYT in August 2004, through which mutual understanding and communications are further enhanced. President Chapela extended his invitation to President chen yiyu to pay a visit to Mexico at his time of convenience to further oromote bilateral coooeration and communication.

From June 28 to July 2, 2006, at the invitation of Prof. Vladislav Yu. Khomich, President of Russian Foundation for Basic Research （RFBR）, an NSFC delegation headed by NSFC President chen yiyu paid a visit to Russia. Established in 1992 and as a result of science and technology system reform and sci-tech globalization, RFBR has seen a continuous increase of funding for basic research in the federal budget for R＆D in the past years The two sides expressed wishes to further the collaboration and to explore new ways to push the cooperation more effective and fruitful. The delegation also visited the Zoological Institute, Russian Academy of Sciences.

Unsupervised person re-identification(re-ID) aims to train a discriminative model without identity annotations. State-of-the-art methods usually follow a clustering-based pipeline, which utilizes a clustering algorithm to generate pseudo-labels and performs model training iteratively. Despite the success of these methods, camera variation has not been well considered in the distance calculation step to reduce noise labels, which is the main reason for noise label generation. To address this problem, we design a plug-and-play method with low computational complexity to improve the distance calculation step in the pseudo-label generation stage. Specifically,(1) to alleviate the influence of intra-camera samples and select reliable inter-camera pairs, we propose inter-camera k-reciprocal nearest neighbor(IKNN) to mine reliable inter-camera positive pairs; and(2) to merge the relationship of reliable inter-camera pairs into the distance for better clustering, we design adaptive inter-camera encouragement(AIE) to encourage the distance of inter-camera positive pairs. Extensive experiments show consistent improvements in comparison with various state-of-the-art unsupervised re-ID methods, demonstrating the wide applicability and efectiveness of our method.
