This paper defines a strong security model for multi-recipient signcryption scheme in the random oracle model, which is semantically secure against adaptive chosen-ciphertext insider attack, existentially forgeable chosen-message attack and anonymous chosen-ciphertext insider attack. By analyzing, we point out that Li-Hu-Liu Multi-Recipient Signcryption Scheme is insecure against the adaptive and anonymous chosen-ciphertext insider attacks.

However, the multi- identities of artists have still been doubt by many people, and the forepassed concept of occupation has always blocked to understand the artist's multi-identities. Artists' intervene in socialty often be regarded as unmindful of their own works or doing other occupations. The identity of the artists in the "rebuilding in art "activity is one aspect of the identities' multiple. But The activity itself has answered to the suspicions, that is ,as for the society, it is good or not to have this kind of activity.

不过，这种艺术家身份的多重性仍然受到众多人的怀疑，职业焦虑一直阻碍着对艺术家多重身份的理解，艺术家介入社会以后，往往会认为是不务正业，或者是做了其他职业的人做的事，&以艺术重建家园&的艺术家身份的这种多重化还只是身份多重化的一个侧面，但这个活动已经对这样的置疑作了回应，即，对社会而言，我们有这样的活动好呢还是没有这样的活动好？

The latter is hydrolyzed in the acidic conditions, then the recovered copolymer of EO and glycidol with multi pending hydroxymethyls is esterified with 2-bromoisobutyrylbromide to produce the ATRP macroinitiator with multi pending bromoisobutyryl groups .

共聚物poly的羟基与2-溴异丁酰溴进行酯化反应，得到侧链挂有2-溴异丁酸酯基结构的可以用于原子转移自由基聚合体系的大分子引发剂Poly_

Both star copolymer precursors are hydrolyzed in the acidic conditions, then the corresponding recovered star copolymers of EO and glycidol with multi pending hydroxylmethyls are esterified with 2-bromoisobutyryl bromide to produce the ATRP macroinitiators with multi pending bromoisobutyryl groups .

在阴离子共聚EPEE单体和环氧乙烷单体的过程中，通过变换引发剂体系中的醇的结构(由原来的二元醇变成多元醇，如三羟甲基丙烷和季戊四醇)，合成了星形结构的共聚物，通过水解反应脱去保护基团后，再与2-溴异丁酰溴反应，得到链的侧端挂有很多2-溴异丁酸酯基的星形大分子引发剂，通过ATRP聚合机理引发苯乙烯聚合得到PEO为主链，PS为侧链的星形一接枝共聚物。

A new gene structure is proposed: head+body+tail, which allows the program with necessary complexity and putting some learning mechanism into the search process.② A new homeotic gene structure is proposed, it not only can call for subroutines easily, but also can automatically perform programming.③ The concept of different homeotic gene, a multi-cellular structure is proposed. It can be used to describe the complex multi-level programs and to implement the complex subroutine calls.④ An estimation of distribution operator for guiding search is proposed. It fuses statistic learning mechanism into the search process to accelerate the convergent process and improve the quality of solutions.
