Egyptian Satirical Graphics on Social Media after the Arab Spring

This paper investigates Egyptian digital forms of satirical graphics mostly published on Social Media by cartoonists and amateurs after the Arab Spring. These include: webcomics memes, and Graphic Interchange Format (GIF). The paper will focus on two Facebook pages as a case study: Asa7be Sarcasm Society and Islam Gawish's Elwarka/The Paper. With this aim in mind, I will show how these forms of political satire incorporate, cinema, theatre, religion, western elements and pan-Arabism to express a political view in a creative manner to appeal to a more diverse and broad audience. The first part of the paper provides a brief discussion of Arabic/Egyptian satire with specific reference to political cartoons and Egyptian youth activism on social media (specifically Facebook). It will also introduce the concept of satirical graphics and some of its concrete applications. The second part describes the methodology and provides an analysis of the case study

Optimization of the PHYDYAS Waveforms Using the POPS Algorithm: POPS-PHYDYAS

International audienceOrthogonal Frequency Division Multiplexing (OFDM) was adopted by the fourth generation (4G) of mobile communication systems to guarantee high data rates with high terminal mobility. However, OFDM ensures strict synchronism and orthogonality, which reduces the throughput and energy efficiency of the communication networks. With the advent of 5G cellular wireless communication systems, the use of non-orthogonal multiplexing schemes, which preserves the OFDM benefits without requiring high-level synchronization, becomes an important research topic. Recently, the POPS algorithm [1] has been introduced as a powerful tool to efficiently design waveforms candidates for 5G. In this paper, we propose a new design of PHYDYAS waveforms namely POPS-PHYDYAS. It is based on the mix of the POPS algorithm and the PHYDYAS filter [2]. The results confirm the advantage behind the POPS-PHYDYAS algorithm in enhancing the performance compared to multicarrier systems using the original PHYDYAS waveforms, as they are conceived by Mirabbasi-Martin [3]. Simulations are given to support our clamis

High level of genetic variation in mitochondrial 16S rDNA among populations of Porcellionides pruinosus (Brandt, 1833) (Crustacea: Isopoda: Oniscidea) in Tunisia

For more than 20 years, the cosmopolitan species Porcellionides pruinosus (Brandt, 1833) has been characterised by a controversial taxonomic status. This “species” has a high ecological plasticity, which enabled it to conquer different kinds of habitats. Besides that, this “species” exhibits a geographical variation in its morphological features and its reproduction pattern. In fact, some Tunisian populations had a seasonal reproductive period and while others showed a reproductive activity. A genetic analysis of rDNA 16S sequences has been performed to compare eight populations of P. pruinosus from different geographical sites, located in the north, centre, and south of Tunisia. Results reveal that the population of Tunis shows considerable variation in the primary structure of the sequences and has a substantial genetic diversity (FST = 0.98 and FCT = 0.97). However, the genetic variation is low for the populations of Bella Regia and Bousalem (0.00041), and null between populations of Elfeija, Chebba, Monastir, Sbiba and Sned. Moreover, the genetic distance of the population of Tunis (≥ 0.35) compared to the other populations raises questions about the taxonomic status of this population. Also, in this latter population transitions are the most dominant variations, whereas for the other seven populations there are only two types of transversion substitutions. The results of the current study emphasise the controversial taxonomic status of Porcellionides pruinosus in Tunisia. Consequently, it would appear that the taxonomic status of P. pruinosus from Tunisia needs a re-evaluation
