Abstract. In this paper we address the problem of protecting elliptic curve scalar multiplication implementations against side-channel analysis by using the atomicity principle. First of all we reexamine classical assumptions made by scalar multiplication designers and we point out that some of them are not relevant in the context of embedded devices. We then describe the state-of-the-art of at...

Most reconstruction methods for genomes of ancient origin that are used today require a closely related reference. In order to identify genomic rearrangements or the deletion of whole genes, de novo assembly has to be used. However, because of inherent problems with ancient DNA, its de novo assembly is highly complicated. In order to tackle the diversity in the length of the input reads, we pro...

Ancient DNA analyses have provided enhanced resolution of population histories in many Pleistocene taxa. However, most studies are spatially restricted, making inference of species-level biogeographic histories difficult. Here, we analyse mitochondrial DNA (mtDNA) variation in the woolly mammoth from across its Holarctic range to reconstruct its history over the last 200 thousand years (kyr). W...

Cosmetics is as old as the history of human being. It has been present in human life since the times of the most ancient civilizations. Perfumery is one of the oldest branches of cosmetics. Valerian perfumes found from the Pharaohs’ pyramids, had maintained their aroma. Coriander, Mace oil, cardamom, cinnamon, and juniper were also the favorite materials used for perfumery in ancient Egyptian c...

MOTIVATIONS Recent progress in ancient DNA sequencing technologies and protocols has lead to the sequencing of whole ancient bacterial genomes, as illustrated by the recent sequence of the Yersinia pestis strain that caused the Black Death pandemic. However, sequencing ancient genomes raises specific problems, because of the decay and fragmentation of ancient DNA among others, making the scaffo...

in this paper the practice of medicine in ancient iran is studied. mythology of ancient iran has many references to how diseases were treated and medicine dispensed. there is even a mention of surgery; presumably the rst caesarian section in the history of medicine is performed for the birth of mythological persian hero, rostam. this study looks at mythology, ancient persian religious texts an...
