Tying up loose ends: ribosome recycling in eukaryotes and archaea.

Ribosome recycling is the final - or first - step of the cyclic process of mRNA translation. In eukaryotes and archaea, dissociation of the two ribosomal subunits proceeds in a fundamentally different way than in bacteria. It requires the ABC-type ATPase ABCE1 [previously named RNase L inhibitor (Rli)1 or host protein (HP)68], but the reaction and its regulation remain enigmatic. Here, we focus...

Tying up Loose Ends in Chondrule Formation by Shocks

Chondrule formation is a long-standing problem in meteoritics. Furnace experiments designed to reproduce chondrule textures constrain their cooling rates between their liquidus and solidus temperatures to be in the range 10-1000 K/hr [1]. This constraint, and nearly all other known constraints on chondrule formation, are satisfied if chondrules were melted by passage through solar nebula shocks...

Tying up the loose ends in fully LZW-compressed pattern matching

We consider a natural generalization of the classical pattern matching problem: given compressed representations of a pattern p[1. . M ] and a text t[1. . N ] of sizes m and n, respectively, does p occur in t? We develop an optimal linear time solution for the case when p and t are compressed using the LZW method. This improves the previously known O((n + m) log(n + m)) time solution of G asien...

Tying up the Loose Ends in Simple, Multiple and Joint Correspondence Analysis

This paper considers several aspects of simple, multiple and joint correspondence analysis that have been misleading, controversial or lacking proper solutions or clarifications. In each case these " loose ends " have been tied up with specific proposals or explanations.
