概括
大型语言模型 (LLM) 可以自动化科学兴趣分析. 使用医学主题标题 (MeSH) 术语生成的个人资料更易于阅读,尽管人类编写的个人资料提供了更多的新概念.
科学领域:
- 生物医学信息学是生物医学信息学.
- 在研究中的人工智能.
背景情况:
- 科学研究资料对于人才发现和合作至关重要.
- 现有的配置文件往往过时,需要自动化和可扩展的解决方案.
- 大型语言模型 (LLM) 为动态配置文件生成提供了一个潜在的解决方案.
研究的目的:
- 设计和评估基于LLM的方法来生成科学兴趣的个人资料.
- 将机器生成的个人资料与研究人员自我总结的兴趣进行比较.
- 评估从PubMed摘要与医学主题标题 (MeSH) 术语中生成的个人资料的性能.
主要方法:
- 开发了两种基于LLM的方法:一种是总结研究人员的摘要,另一种是使用MeSH术语.
- GPT-4o-mini被用来生成来自哥伦比亚大学欧文医疗中心的595名研究人员的摘要.
- 为了进行比较,使用了自动化指标 (ROUGE-L,BLEU,METEOR,BERTScore,KL Divergence) 和手动评估.
主要成果:
- 自动化指标显示,机器生成的和人类编写的个人资料之间的词汇重叠很小,但语义相似性中等 (BERTScore F1:~0.55).
- 手动转述的摘要获得了更高的相似性 (F1: 0.851).
- 基于MeSH的个人资料显示出优越的可读性 (93.44%的好评),并且在67.86%的手册评论中更喜欢,尽管与人写的个人资料相比,关键词使用和事实准确性存在差异.
结论:
- 在科学兴趣分析的可扩展自动化方面,LLM显得有前途.
- 基于MeSH的LLM生成的配置文件提供了比基于抽象的更好的可读性.
- 虽然LLM可以生成语义上类似的配置文件,但人类撰写的摘要往往会引入更多的新概念.

Improving Translational Accuracy
14.0K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Ribosome Profiling
4.0K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Scaling
545
In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Language and Cognition
702
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Aggregates Classification
962
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...
