1922年6月中共接受共产国际指示,结合中国国情,提出了主要是与国民党合作的民主主义的联合战线。中共最初反对共产国际提议的加入国民党的合作方式,希望建立党外合作。在党外合作遭孙中山拒绝后,中共党内产生抛开国民党,“另造一个民族党”并与之合作,建立民主革命联合战线的备用方案,并由此发起民权运动大同盟以为“第三党”之预备。西湖会议上中共迫于共产国际压力同意与国民党进行党内合作。但此后由于苏俄与国民党的联盟尚未完成,国共党内合作亦未入正轨,中共继续发展民权运动大同盟这一预备“第三党”。及至“二七惨案”使中共认识到必须与国民党切实合作且国民党已改组巩固,民权运动大同盟才逐渐停止活动。由此观之,1926年蔡和森在莫斯科偶遇胡适并劝其组党,则可视为中共在国共合作发生危机时,“另造一个民族党”方案的再度尝试。

Having the advantages of certificateless signature and the aggregate signature at the same time,certificateless aggregate signature has been widely applied in e-business, e-government and software security since it was proposed in 2007. Although a number of certificateless aggregate signature schemes have been proposed, all of them are based on the classic number theory problem,which are no longer secure in the quantum era. In this paper, a certificateless sequential aggregate signature over number theory research unit lattice is proposed, which is proven to be secure in random oracle model. Moreover,we extend the new scheme into an efficient certificatebased sequential aggregate signature which is also secure in quantum era.

The development of novel simple, and convenient techniques for the fabrication of porous carbon materials with desirable properties, such as tunable pore structures and the presence of nitrogen functionalities, from renewable and abundant biomasses is required. We herein describe an in situ directing method for the preparation of a nitrogen-doped flower-like porous carbon （NFPC） employing arbitrarily shaped MgO from bio-derived glucosamine chloride （GAH）. Experimental evidence demonstrated that the structure directing effect of the Mg（OH）2 nanosheets formed in situ from MgO hydrolysis was key to this process, with the original MgO morphology being irrelevant. Furthermore, this method was applicable for a wide variety of biomass-derived carbon precursors. The resulting NFPC exhibited a high nitrogen content of 〈9 wt.%, and was employed as a support to anchor small Ru nanoparticles （average size = 2.7 nm）. The resulting Ru/NFPC was highly active in heterogeneous hydrogenations of toluene and benzoic acid, which demonstrated the advantages of nitrogen doping in terms of boosting catalytic performance.

Intuitively, not only do ratings include abundant information for learning user preferences, but also reviews accompanied by ratings. However, most existing recommender systems take rating scores for granted and discard the wealth of information in accompanying reviews. In this paper, in order to exploit user profiles’ information embedded in both ratings and reviews exhaustively, we propose a Bayesian model that links a traditional Collaborative Filtering(CF) technique with a topic model seamlessly. By employing a topic model with the review text and aligning user review topics with 'user attitudes'(i.e., abstract rating patterns) over the same distribution, our method achieves greater accuracy than the traditional approach on the rating prediction task. Moreover, with review text information involved, latent user rating attitudes are interpretable and 'cold-start' problem can be *** property qualifies our method for serving as a 'recommender' task with very sparse datasets. Furthermore,unlike most related works, we treat each review as a document, not all reviews of each user or item together as one document, to fully exploit the reviews’ information. Experimental results on 25 real-world datasets demonstrate the superiority of our model over state-of-the-art methods.
