Monkeypox virus quadrivalent mRNA vaccine induces immune response and protects against vaccinia virus

作者： jiaxin fang Chunwu Liu College of Artificial Intelligence National University of Defense Technology

Polar codes using successive-cancellation decoding always suffer from high latency for its serial nature. Fast simplified successive-cancellation decoding. algorithm improves the situation in theoretically but not performs well as expected in practical for the workload of nodes identification and the existence of many short blocks. Meanwhile, Neural network（NN） based decoders have appeared as potential candidates to replace conventional decoders for polar codes. But the exponentially increasing training complexity with information bits is unacceptable which means it is only suitable for short codes. In this paper, we present an improvement that increases decoding efficiency without degrading the error-correction performance. The long polar codes are divided into several sub-blocks, some of which can be decoded adopting fast maximum likelihood decoding method and the remained parts are replaced by several short codes NN decoders. The result shows that time steps the proposed algorithm need only equal to 79.8% of fast simplified successive-cancellation decoders require. Moreover, it has up to 21.2 times faster than successive-cancellation decoding algorithm. More importantly, the proposed algorithm decreases the hardness when applying in some degree.

社会组织党建的政策演进以“历史使命驱动政治整合”为主线，即中国共产党紧密结合不同历史时期社会环境与主要任务，从组织、意识形态与角色等维度对社会组织进行政治整合。对社会组织党建政策文本进行分析发现：组织整合是党坚持的主要整合方式，是政治整合的基础，意识形态整合与角色整合构成政治整合的实质，后两者以组织整合为前提，随党组织建设逐步发挥整合作用。社会组织党建政策反映出党对社会组织的关系特征，既具有恒定不变性，又具有灵活适应性。社会组织党建政策演进历程启示新时代社会组织党建工作，要立足历史使命，回应时代发展需求；夯实组织基础，推进党建工作制度化；筑牢思想根基，发挥党员先锋模范作用。

为准确快捷计算煤层底板破坏深度,保证工作面安全生产以及防治水措施的制定,须建立多影响因素下的煤层底板破坏深度统计公式。通过获取的文献与现场资料,得到国内92组煤层底板破坏深度的实测结果,选取其中80组利用灰色关联度理论和多元线性回归方法分析了采深、工作面斜长、煤层倾角、采高对煤层底板破坏深度的影响权重,构建了煤层底板破坏深度的计算模型,并对其余12组实测数据进行了模型检验,结果表明:煤层采深采深>煤层倾角>采高;煤层采深≥500m时,各影响因素对煤层底板破坏深度的影响权重顺序为:采深>工作面斜长>采高>煤层倾角。基于灰色关联度理论分析,采用SPSS软件多元线性回归分析模型得到4种煤层底板破坏深度经验公式,通过预测值与实测值对比发现,预测值与实测值随煤层采深的增加具有相同的变化特点。同时,检验结果表明,煤层采深≥500m时的绝对误差和相对误差较煤层采深<500m时略大,但从整体来看,两类公式预测值平均绝对误差均小于3m,平均相对误差均小于20%,预测值与实测值较为接近。研究成果可为煤层底板破坏深度预测提供参考。
