遗传诊断中的一个关键挑战是评估与剪接相关的致病遗传突变.现有致病剪接突变预测工具大多基于传统的机器学习方法,主要依赖人工提取的剪接特征,从而限制预测性能的提升,尤其对于非经典剪接突变,性能较差.因此,文中提出基于BERT(Bidirectional Encoder Representations from Transformers)和CNN(Convolutional Neural Network)的致病剪接突变预测方法(BERT and CNN-Based Deleterious Splicing Mutation Prediction Method,BCsplice).BCsplice中BERT模块可全面提取序列的上下文信息,与提取局部特征的CNN结合后,可充分学习序列的语义信息,预测剪接突变致病性.非经典剪接突变的影响往往更依赖序列上下文的深层语义信息,通过CNN将BERT的多级别语义信息进行组合提取,可获得丰富的信息表示,有助于识别非经典剪接突变.对比实验表明BCsplice性能较优,尤其是在非经典剪接区表现出一定性能优势,有助于识别致病剪接突变和临床遗传诊断.

碳普惠制是一种基于市场信号的激励机制,核心在于助推参与者作出符合公共利益的绿色低碳决策。由于本身具有公共属性,碳普惠制的减排目标实现离不开政府的有效引导,应深入分析实际场景下不同的碳普惠设计模式。基于管理和流转两个维度,可区分出四类碳普惠模式和场景,并据此从交易动机、激励机制和运行机制等方面考察现有的实践案例。进一步地,围绕不同碳普惠模式的得失,总结出政府主导型碳普惠模式的优化方案,包括构建组织管理体系,框定体系顶层架构,设计低碳减排场景,构建减排量资产化机制,搭建消纳交易市场等。最后,提出激励企业和公众践行绿色低碳行为的相关政策建议,助力实现“双碳”目标。

BACKGROUND:Resuscitative endovascular balloon occlusion of the aorta(REBOA)can temporarily control traumatic ***,its prolonged use potentially leads to ischemia-reperfusion injury(IRI).Partial REBOA(pREBOA)can alleviate ischemic burden;however,its security and eff ectiveness prior to operative hemorrhage control remains ***,we aimed to estimate the effi cacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic ***:Twenty Landrace pigs were randomized into control(no aortic occlusion)(n=5),intervention with complete REBOA(cREBOA)(n=5),continuous pREBOA(C-pREBOA)(n=5),and sequential pREBOA(S-pREBOA)(n=5)*** the cREBOA and C-pREBOA groups,the balloon was inflated for 60 *** hemodynamic and laboratory values were compared at various observation time *** samples immediately after animal euthanasia from the myocardium,liver,kidneys,and duodenum were collected for histological assessment using hematoxylin and eosin ***:Compared with the control group,the survival rate of the REBOA groups was prominently improved(all P<0.05).The total volume of blood loss was markedly lower in the cREBOA group(493.14±127.31 mL)compared with other groups(P<0.01).The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups(P<0.05).At 120 min,the S-pREBOA group showed higher alanine aminotransferase(P<0.05)but lower blood urea nitrogen compared with the cREBOA group(P<0.05).CONCLUSION:In this trauma model with liver injury,a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure,despite persistent *** tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures,and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.

作者： chengcheng song Shandong Jianzhu University Philipps University of Marburg

Psychoanalytic criticism is an important branch of literary criticism that applies theories of psychology to the study of literature. The present paper attempts to analyze Poe's detective story "The Murders in the Rue Morgue" from a psychoanalytic perspective. Poe's skillful characterization and employment of the double motif is intensively discussed. It also deserves noting that the story conveys sensitive messages and exerts influence on readers' psychology.

利用长江口1982-2010年间4个年份的高精度实测地形数据、大通站输沙量数据以及河口工程建设信息等,分3个阶段研究了长江口整体冲淤规律、不同分区冲淤变化时空差异、重点断面垂向冲淤特征、水下三角洲重要区域(崇明东滩、横沙浅滩、九段沙以及南汇东滩)的演变趋势与受控因素。结果表明:(1)近30年长江口整体上表现为略微冲刷,冲刷面积占51.83%,在3个阶段中呈现出"冲刷—淤积—再冲刷"的冲淤演化态势,且冲淤变化时空差异显著,仅长江北港区为持续冲刷。(2)崇明东滩和横沙浅滩东侧和北侧、九段沙北侧以及南汇东滩的5 m以浅区域以垂向淤积为主,而崇明东滩和横沙浅滩南侧、九段沙东侧和南侧的5 m以浅区域则以垂向冲刷为主。(3)长江口重要区域2 m和5 m等深线包络面积整体上是不断增加的,1982-2010年时段内年均增加量分别为10.42 km2/a和7.99 km2/a,但各分区则表现不一致;10 m等深线包络面积在整体上及各个分区内均表现为明显减小;15 m等深线包络面积变幅较小,基本保持稳定状态;(4)受河口工程建设影响,仅崇明东滩水下三角洲等深线包络面积减小的趋势与大通站输沙量减少趋势相同。主要结论:从长江口水下三角洲等深线包络面积和分布形态的变化看,基于目前上游输沙量持续减少的宏观自然背景下,大规模的河口工程建设对近年来长江口水下三角洲演变的控制作用日益明显。
