财务共享模式随着集团公司的兴起逐步发展起来,但在其发展的过程中存在着诸如财务中心总分架构不合理、审批流程复杂以及数据集中度风险等问题,限制了财务共享中心的进一步发展。基于联盟区块链提出了一种新型财务共享模式,将整个财务共享系统分为业务模块、资金模块以及战略模块,将子公司财务处和财务共享中心业务模块、资金模块纳入一个联盟链,利用委托权益证明(DPoS)共识机制共同维护一个账本,将层级操作变为扁平化操作,降低了运营成本。同时通过在业务层和共识层引入智能合约,将重复性操作写入合约中,满足条件自动执行,大大解放了人力,节约了人力资本。此外联盟链利用P2P网络,实现了账本的去中心,通过数据共享的方式,很好解决了本地依赖性业务缺乏敏感性的问题。最后基于区块链的时间戳和数字签名,保证了信息的可追溯性,提高了数据的安全性与完整性,为财务共享模式目前的发展困境找到了新的出路。

面孔吸引力被认为能够影响注意资源的分配。然而,对于面孔吸引力影响注意资源分配的具体机制目前仍不明确。本研究想探究面孔吸引力对两种注意过程的影响:注意捕获和注意粘附。注意粘附指的是将注意转移的困难,而注意捕获指的是注意的初始定向过程。本研究会采用不同的视觉搜索范式来测量面孔吸引力对这两种不同的注意过程的影响,尤其是在注意捕获中又区分了自上而下和自下而上两种注意捕获。并且因为面孔吸引力的进化意义,本研究还会考察在不同的进化动机状态下(自我保护和择偶动机)面孔吸引力对注意的影响。

Background 3-deazaueplanocin A(DZNep)is a global histone methylation inhibitor that reactivates developmental genes not silenced by DNA methylation. In our previous study,we have reported that DZNep can control ongoing graft-versus-host disease(GVHD)in mice after allogeneic hematopoietic stem cell transplantation through modulating the immune responses of alloreactive effector T cells. Methods Using rat renal transplantation model(Wistar-Lewis),we investigated whether in vivo administration of DZNep can ameliorate and/or prevent acute renal allograft *** allografts and peripheral blood were collected on day 5 after transplantation for further mechanism investigation.
