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...
cognitive linguistics gives the most inclusive, consistent description of how language is organized, used and learned to date. cognitive linguistics contains a great number of concepts that are useful to second language learners. if-clauses in english, on the other hand, remain intriguing for foreign language learners to struggle with, due to their intrinsic intricacies. efl grammar books are ...
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
فرض کنید m یک منیفلد جهت دار باشد در این پایان نامه با استفاده از علامت منیفلد l، m-کلاس هایزبروچ را تعریف خواهیم کرد. با بکارگیری علامت برتر و پایایی هموتوپی حدس نویکوف برای pi = z بدست می آید. در سفتی توپولوژیکی هموتوپیک بودن یک هم ارزی هموتوپی با یک همئومورفیسم یا دیفئومورفیسم بررسی می شود. با معرفی نگاشت کونر- فلوید و استفاده از نظریه جراحی و ارتباط آن با کلاس...
