AMBER (Assisted Model Building through Energy Refinement) is a molecular dynamics package that is widely used to simulate the motion of large biological molecules such as proteins and DNA. The version of AMBER investigated here is 4.1, the latest in a series jointly developed over many years by the research groups of Peter Kollman at the University of California, San Francisco, and David Case o...

A preliminary study on fossil scorpions found in amber, from the Lower Cretaceous through the Palaeocene and up to the Miocene is proposed. Scorpions remain rare among the arthropods found trapped in amber. Only 24 specimens are known from Cretaceous amber, representing eight families and subfamilies, ten genera and 21 species; in parallel, 10 specimens have been recorded from Baltic amber repr...

Amber (UAG) and opal (UGA) nonsense suppressors were constructed by oligonucleotide site-directed mutagenesis of two Drosophila melanogaster leucine-tRNA genes and tested in yeast, Drosophila tissue culture cells and transformed flies. Suppression of a variety of amber and opal alleles occurs in yeast. In Drosophila tissue culture cells, the mutant tRNAs suppress hsp70:Adh (alcohol dehydrogenas...

OBJECTIVES Patients who are deteriorating, with uncertain recovery and with a short prognosis often have complex needs. The AMBER care bundle systematically manages these patients by promoting consistent communication and care planning. To describe how the AMBER bundle is applied in a UK hospital. To identify factors affecting the use of the AMBER bundle in patients who subsequently died. To ga...

All entomological traps have a capturing bias, and amber, viewed as a trap, is no exception. Thus the fauna trapped in amber does not represent the total existing fauna of the former amber forest, rather the fauna living in and around the resin producing tree. In this paper we compare arthropods from a forest very similar to the reconstruction of the Miocene Mexican amber forest, and determine ...

Introduction The Amber language embeds many recent ideas in programming language design, and tries to introduce all the features in their minimal, essential, form. One of its main goals is to safely blend static typing with the dynamic requirements of a system programming language. For this purpose, multiple inheritance and persistent objects are integrated in a strongly typed language. Other f...

Thirteen species of basal Brachycera (11 described as new) are reported, belonging to nine families and three infraorders. They are preserved in amber from the Early Cretaceous (Neocomian) of Lebanon, Albian of northern Spain, upper Albian to lower Cenomanian of northern Myanmar, and Late Cretaceous of New Jersey USA (Turonian) and Alberta, Canada (Campanian). Taxa are as follows, with signific...

The Amber machine is a stack machine designed as an intermediate language for compiling higher-order languages. The current version is specialized for the Amber language. The machine supports a set of basic and structured data types, functional closures, signals, bitmap graphics, persistent objects and meta-level execution. The latter is needed as the Amber compiler is entirely written in Amber...

We have compared molecular dynamics (MD) simulations of a β-hairpin forming peptide derived from the protein Nrf2 with 10 biomolecular force fields using trajectories of at least 1 μs. The total simulation time was 37.2 μs. Previous studies have shown that different force fields, water models, simulation methods, and parameters can affect simulation outcomes. The MD simulations were done in exp...
