With an exception of aphids, insects' 28S rRNA is thought to harbor a "hidden break" which cleaves under denaturing conditions to comigrate with 18S rRNA band to exhibit a degraded appearance on native agarose gels. The degraded appearance confounds determination of RNA integrity in laboratories that rely on gel electrophoresis. To provide guidelines for RNA profiles, RNA from five major insect...

The term “mid-term break” is frequently attributed to the half at schools—a short vacation season for students. However, as one of Irish poet Seamus Heaney’s poem, it represents a new period, characteristic transition from situation another. Through this autobiographical poem narrating his brother Christopher's death, Heaney presents moment which may happen anyone, far away emotions possible, w...

The two-break unit root test of Lumsdaine and Papell (1997) is examined and found to suffer from bias and spurious rejections in the presence of structural breaks under the null. A two-break minimum LM unit root test is proposed as a remedy. The two-break LM test does not suffer from bias and spurious rejections and is mostly invariant to the size, location, and misspecification of the breaks. ...

This paper describes the multi-level annotation process of Urdu speech corpus and its quality assessment using PRAAT. The annotation of speech corpus has been done at phoneme, word, syllable and break index levels. Phoneme, word and break index level annotation has been done manually by trained linguists whereas syllable-tier annotation has been done automatically using template matching algori...

An in vitro system based upon extracts of Escherichia coli infected with bacteriophage T7 was used to study the mechanism of double-strand break repair. Double-strand breaks were placed in T7 genomes by cutting with a restriction endonuclease which recognizes a unique site in the T7 genome. These molecules were allowed to repair under conditions where the double-strand break could be healed by ...

It has been suggested that existing estimates of the long-run impact of a surprise move in income may have a substantial upward bias due to the presence of a trend break in 1970s (1350s) and 1980s (1360s) gross domestic product (contained oil) data of Iran. This article shows that the statistical evidence does not warrant abandoning the no-trend-break null hypothesis at the 5% significance leve...
