Since its first description more than four decades ago, the atypical endometrial change associated with chorionic tissue effect has been widely confirmed in the literature. However, errors and inaccuracies in text books and other publications often occur. This review clarifies some of these misconceptions and presents a summary of new data on the histologic and immunohistochemical characteristi...

We describe the development of the KandISTI family of model checkers from its origins nearly two decades ago until its very recent latest addition. Most progress was made, however, during two integrated European projects, AGILE and SENSORIA, in which our FM&&T lab participated under the scientific coordination of Martin Wirsing. Moreover, the very name of the family of model checkers is partly ...

More than 100 years ago, Lord Kelvin insightfully observed that measurement is vital to deep knowledge and understanding in physical science. During the last few decades, researchers have made various attempts to develop measures and systems of measurement for computer security with varying degrees of success. This paper provides an overview of the security metrics area and looks at possible av...

Mortality, birth rates and retirement play a major role in demographic changes. In most cases, mortality rates decreased in the past century without noticeable decrease in fertility rates, this leads to a significant increase in population growth. In many poor countries like Palestinian territories the number of births has fallen and the life expectancy increased. In this article we concentrate...

There is a renewed interest for Quantitative genetics since the genomic revolution. Quantitative or complex traits are those controlled by multiple genes so that the inheritance of such complex traits is non-Mendelian, although each individual gene shows Mendelian inheritance. With the advent of genomic tools, for example Next Generation Sequencing (NGS) and deep NGS sequencing of RNA transcrip...

The impact of histone acetylation on transcription was revealed over 50 years ago by Allfrey and colleagues. However, it took decades for an understanding of the fine mechanism by which this posttranslational modification affects chromatin structure and promotes transcription. Here, we review breakthroughs linking histone tail acetylation, histone dynamics, and transcription. We also discuss th...

The search for the standard model Higgs boson at the Large Hadron Collider (LHC) started more than two decades ago. Much innovation was required and diverse challenges had to be overcome during the conception and construction of the LHC and its experiments. The ATLAS and CMS Collaboration experiments at the LHC have discovered a heavy boson that could complete the standard model of particle phy...

Kattel et al (Reports, 24 March 2017, p. 1296) report that a zinc on copper (Zn/Cu) surface undergoes oxidation to zinc oxide/copper (ZnO/Cu) during carbon dioxide (CO2) hydrogenation to methanol and conclude that the Cu-ZnO interface is the active site for methanol synthesis. Similar experiments conducted two decades ago by Fujitani and Nakamura et al demonstrated that Zn is attached to format...

The topic of Orientalism is not one the topics that has been touched upon for first time, but in last two decades repeatedly writings, books, lectures, press articles, and investigations magazines periodicals. However; perspective was constantly changing until it ended up with image could be considered clear minds. As time passed, began to become obvious its dimensions turned evident, some scho...
