Analyzing the Adoption Rate of Local Variable Type Inference in Open-source Java 10 Projects
Type Inference is used in programming languages to improve writability. In this paper, we will be looking more specifically at Local Variable Type Inference (LVTI). For those unfamiliar with LVTI, we will also give an in-depth explanation of what it is and how it works. There is a lot of debate surrounding Type Inference in modern day programming languages. More specifically, whether the costs associated with LVTI outweigh the benefits. It has found its way into many higher-level languages including C#, C++, JavaScript, Swift, Kotlin, Rust, Go, etc. In this paper, we will look at the usefulness of LVTI and its popularity since the release of Java 10. Our study will show that LVTI in Java has not received widespread adoption. We will also explain a possible reason for this is based on the information we have gather from our empirical study which involved statically analyzing 6 popular open source Java 10 projects. We will also discuss different scenarios in which Type Inference can obscure different programming errors

Turnip yellow mosaic virus and cell-free protein synthesis
A polypeptide - synthesising cell-free system directed by Poly-U or Turnip Yellow Mosaic Virus-RNA was derived from imbibed seeds of Phaseolus aureus; this in vitro system was dependent upon exogenous tRNA. The Poly-U-directed system functioned in the presence of tRNAs from P.aureus, Vicia faba and yeast, whereas TYMV-RNA was translated only in the presence of tRNAs from P.aureus or V.faba. This translation barrier was related to the inability of the P.aureus high-speed supernatant enzyme fraction to charge various "protein" amino acids to yeast tRNA under uniform conditions. Such incompatibility did not exist in the Poly-U system where incubation conditions were constructed to favour only one amino acid, i.e. phenylalanine. The P.aureus enzyme fraction promoted esterification of valine to TYMV-RNA. More rigorous conditions were required for the translation of Poly-U in a Transfer System with yeast tRNA than with V.faba tRNA. Poly-U and TYMV-RNA competed for ribosomal binding sites. The characteristics of synthetic and natural templates in amino acid incorporation were correlated
