In the last decade the interest in deformation theory has grown in many areas of mathematics and physics. The deformation question is completely solved by describing a ‘‘versal’’ deformation of the given object; such a deformation induces all the other deformations. This problem turns out to be hard and a general procedure for solving this was given only recently in FF2 for Lie algebras. It is ...

In the last decade, niche construction has been heralded as the neglected process in evolution. But niche construction is just one way in which the organism's interaction with and construction of the environment can have potential evolutionary significance. The constructed environment does not just select for, it also produces new variation. Nearly 3 decades ago, and in parallel with Odling-Sme...

under an intensive competitive environment, the construction industry is facing pressure to meet the higher customer expectations under a tighter budget. on the other hand, construction is one of the main sectors generating greenhouse gases. according to published statistics, construction industry is one of the most important resources of greenhouse emissions in the world. therefore, based on t...

In this survey article, we revisit construction of simple continued fractions of quadratic irrationals with long period lengths, which has generated much interest in the relatively recent literature. We show that new and not-sonew results actually follow from results of Perron in the 1950s and from results of this author from over a decade ago. Moreover, we are able to generalize and simplify n...

Development of an effective malaria vaccine remains one of the biggest challenges faced by modern science. Although in the last decade tremendous advances have taken place in the design, construction and testing of malaria vaccines, many questions still remained unanswered. This review highlights exclusively some of the exciting and most recent progress in the development and clinical testing o...

Diversity-oriented synthesis (DOS) is an important field involving the synthesis of libraries of diverse small molecules for applications including biological screening. The last decade has witnessed major progress in the field, with continued emphasis on structural and functional diversity for DOS library construction. A number of recent reviews have updated the community on this topic, includ...

Bessen and Meurer (2008) theorize that a breakdown in notice of patent boundaries caused the patent litigation surge of the 1990s. They argue a prime source of this breakdown was the proliferation of software patents with particularly uncertain scope. In this paper I seek evidence that software patent scope is more uncertain by extending the empirical literature on claim construction reversal r...
