simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...

The identification of species at risk of extinction is a central goal of conservation. As the use of data compiled for IUCN Red List assessments expands, a number of misconceptions regarding the purpose, application and use of the IUCN Red List categories and criteria have arisen. We outline five such classes of misconception; the most consequential drive proposals for adapted versions of the c...

A Hille-Yosida Theorem is proved on convenient vector spaces, a class, which contains all sequentially complete locally convex spaces. The approach is governed by convenient analysis and the credo that many reasonable questions concerning strongly continuous semigroups can be proved on the subspace of smooth vectors. Examples from literature are reconsidered by these simpler methods and some ap...

Prioritization and selection of sample areas from the whole nature is necessary to protect biodiversity. The main purpose of this study was to evaluate the development of a network of conservation areas in Markazi province using landscape metrics. For this purpose, we used MaxEnt, Marxan, Fragstat softwares and eight conservation criteria. Results were compared by using simulated sorting, greed...

It is impractical to implement conservation efforts for all species due to complexity of natural systems, large scale of biodiversity issues, and budget limitations. Prioritizing species of conservation importance can alleviate this issue. Multiple interrelated criteria may be used for conservation prioritization of species. Therefore, the accurate evaluation of criteria is a multi-criteria dec...

MOTIVATION Amino acid sequence alignments are widely used in the analysis of protein structure, function and evolutionary relationships. Proteins within a superfamily usually share the same fold and possess related functions. These structural and functional constraints are reflected in the alignment conservation patterns. Positions of functional and/or structural importance tend to be more cons...

Abstract All stages of the Conservation of historical properties must be done according to criteria that are in fact the separator of the correct from the incorrect. Some criteria are general and apply to all types of historical artworks, and some of them can be considered more limited to some types of historical artifacts. Canvas-marouflaged murals, like other historical artworks, are no exce...
