德雷福斯解决文明间伦理冲突的方案

德雷福斯认为,受现代性思想影响,自笛卡尔以来的主流认识论都是一种“中介理论”的思想。中介理论认为人类获取知识需要通过某个中介,它区分了内心观念世界与外部实在世界,确立了物质与精神的二元秩序,并将效率是否优先作为评判一个文明中所有伦理规范是否具有价值的标准,这种认识论造成了现代文明在不同背景下的伦理冲突。德雷福斯提出了“接触理论”的认识论,认为人们可以直接接触实在,实在存在多元的面向。总之,不同背景下的文明的伦理规范都是有其独特的意义的,没有一个文明可以用自己所处的文明的伦理规范来衡量其他文明习俗的价值,而应当将其他文明的伦理规范放在自己所处的文明中的相等位置来对待。接触理论能够拥抱人类文明价值的复杂性与多样性,展开文明间对话的可能。

lactobacillus delbrueckii subsp. bulgaricus(l. bulgaricus) and Streptococcus thermophilus(S. thermophilus) are commonly used starters in milk fermentation. Fermentation experiments revealed that l. bulgaricus-S. thermophilus interactions(lbSt I) substantially impact dairy product quality and production. Traditional biological humidity experiments are time-consuming and labor-intensive in screening interaction combinations, an artificial intelligence-based method for screening interactive starter combinations is necessary. However,in the current research on artificial intelligence based interaction prediction in the field of bioinformatics, most successful models adopt supervised learning methods, and there is a lack of research on interaction prediction with only a small number of labeled ***, this study aimed to develop a semi-supervised learning framework for predicting lbSt I using genomic data from 362 isolates(181per species). The framework consisted of a two-part model: a co-clustering prediction model(based on the Kyoto Encyclopedia of Genes and Genomes(KEGG) dataset) and a laplacian regularized least squares prediction model(based on K-mer analysis and gene composition of all isolates datasets). To enhance accuracy, we integrated the separate outcomes produced by each component of the two-part model to generate the ultimate lbSt I prediction results, which were verified through milk fermentation experiments. Validation through milk fermentation experiments confirmed a high precision rate of 85%(17/20; validated with 20 randomly selected combinations of expected interacting isolates). Our data suggest that the biosynthetic pathways of cysteine, riboflavin, teichoic acid, and exopolysaccharides, as well as the ATP-binding cassette transport systems, contribute to the mutualistic relationship between these starter bacteria during milk fermentation. However, this finding requires further experimental verification. The presented model and data are valua

青藏高原位于印度板块与欧亚板块碰撞的前沿地带,地壳运动十分活跃.受高海拔、高寒气候等因素的限制,以地面观测站为代表的传统大地测量监测较为困难,因此至今青藏高原的高空间分辨率地壳形变场尚未精确测定. InSAR技术不受地面观测条件限制,能够获得大范围、高空间分辨率的地壳形变场,在青藏高原地壳形变监测领域具有不可替代的优势.本文利用2014~2020年的Sentinel-1卫星SAR数据,计算了青藏高原升降轨InSAR形变场,测量精度约为3mm/a.在此基础上,融合InSAR与GNSS数据,获取了覆盖青藏高原的千米分辨率三维地壳形变场和应变率场.通过球面小波多尺度分析,将三维形变场分解出不同波长的形变,其中波长小于110km的形变主要来自断层运动、震后形变和其他非构造形变,大于110km的形变主要来自大范围的构造运动.研究结果显示,高原中部地区呈现大范围下沉,而喜马拉雅弧地区则呈现明显隆升,这表明青藏高原可能已经停止了整体隆升并进入了局部坍塌阶段.此外,不同空间尺度的三维形变场表明,青藏高原在短波长变形中表现为非连续形变,在长波长中则表现为连续形变.本文研究结果有助于调节青藏高原块体变形模型和连续变形模型之间的争议.

随着新能源装机规模和占比的不断扩大,未来新型电力系统对灵活调节能力的需求逐步攀升。目前,我国仍以煤炭为主要能源,电源结构仍以煤电机组为主。在新能源大规模并网条件下,煤电逐步由传统的基础保障性电源向系统调节性电源转变,更多地承担系统调峰和备用等任务,以促进新能源的消纳。因此,充分发挥煤电机组的灵活调节能力对于电力系统的安全稳定经济运行至关重要。该文在考虑风电不确定性的基础上建立了计及煤电机组深调和储能的电力系统两阶段分布鲁棒优化模型。模型第一阶段考虑基础场景下系统的调度计划,包括煤电机组的启停和储能的充放电计划,第二阶段在第一阶段决策已知的情况下优化不确定概率分布下的成本期望,从而得到最恶劣场景下的概率分布。模型采用非精确列和约束生成(inexact column-and-constraint generation,i-C&CG)算法迭代求解。最后,采用改进的IEEE-39节点和IEEE-300节点系统验证了模型对风电消纳的促进作用以及i-C&CG算法对模型求解的加速效果。
