于是有了BASE理论。 BASE 理论 eBay的架构师Dan Pritchett源于对大规模分布式系统的实践总结,在ACM上发表文章提出BASE理论,BASE理论是对CAP理论的延伸,核心思想是即使无法做到强一致性(StrongConsistency,CAP的一致性就是强一致性),但应用可以采用适合的方式达到最终一致性(Eventual Consitency)。 (Basically Available)基...
Figure 2 is a simple schema that illustrates consistency considerations for BASE. The user table holds user information including the total amount sold and bought. These are running totals. The transaction table holds each transaction, relating the seller and buyer and the amount of the transaction....
The enzymatic kinetics (Figure 4A, right; for details, see the supplemental information) also showed the same trend (Vmax and Km; see Table 1; through this work, error bars were the standard deviations of conducting each measurement three times under the same conditions). This result indicates...
The separation factors and the resolutions for the resolution of β-amino acids on CSP 10 were compared with those on CSP 6 and CSP 8 in Table 5. CSP 10 is a type of CSP 6 or CSP 8 in that the three CSPs contain N–H amide linkage. In this instance, the comparison of the ...
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp

acid and base treatments (Fig.4b andSupplementary Table3). Especially,Rshof HNO3-doped graphene after sodium hydroxide treatment was unmeasurable using the 4-point probe method; this result can be attributed to tearing of the surface of HNO3-doped graphene by treatment with strong base chemicals ...
Delta lake是一个具有事务ACID语义的table storage系统,底层基于常见的云对象存储(S3/Blob Storage...)或分布式文件系统(HDFS)。在实现了事务能力后,基于Delta lake又可以构建一系列类似数仓的上层特性,因此可以说它是lakehouse的核心组件之一。 本篇文章是对《Delta Lake: HighPerformance ACID Table Storage over Clou...
1. Overall, the weighted mean age was 40.5 years old, 70.6% was non‐Hispanic white, and the average SUA level was 5.9 mg/dL. The weighted distributions of population characteristics according to SUA quartiles were demonstrated in Table 1 and Table 2. Significant differences were observed ...
6.2.3.2Base-free oxidation of glucose induced by microwave on gold nanoparticle Microwave-assisted base-free oxidation of glucose togluconic acidusing gold nanoparticle catalysts was reported[72]. During the process, high conversion and selectivity were obtained in a short time (10min) and gluconic ...
