A feasibility study for implementing the AES encryption algorithm in hardware achieving 500 Gbits/s is presented. The methodology followed in the process of obtaining the solution allowed us to reach a highly regular solution that is scalable

An Efficient Network-on-Chip Architecture Based on the Fat-Tree (FT) Topology

A novel approach for an efficient network-on-chip using a modified Fat Tree is presented. Contention is eliminated and latency is reduced through an improved topology and router architecture. The adopted topology increases performance without a substantial increase in the routing cost. This is achieved by using an improved buffer-less, paremeterizable router architecture. The proposed router architecture is simple to implement yet can achieve the required packet collision avoidance. Simulation results that show the level of performance achieved by both the topology and the router architecture are presented. A throughput of more than 90% is achieved way above the 40-50% usually seen in other networks on chips

Les reboisements en chêne-liège en Algérie, entre contraintes écologiques et exigences techniques

En Algérie, les forêts de chêne-liège ont connu une régression alarmante. Pour remédier à cette situation, le gouvernement algérien a lancé un plan national de reboisement qui a conduit, à ce jour, à la réalisation de 18 500 hectares. Malheureusement, le taux de réussite moyenne national reste faible. Cet article essaie de tirer les enseignements de ces travaux de reboisement en chêne-liège

Critical assessment of protein intrinsic disorder prediction (CAID) - Results of round 2

Protein intrinsic disorder (ID) is a complex and context-dependent phenomenon that covers a continuum between fully disordered states and folded states with long dynamic regions. The lack of a ground truth that fits all ID flavors and the potential for order-to-disorder transitions depending on specific conditions makes ID prediction challenging. The CAID2 challenge aimed to evaluate the performance of different prediction methods across different benchmarks, leveraging the annotation provided by the DisProt database, which stores the coordinates of ID regions when there is experimental evidence in the literature. The CAID2 challenge demonstrated varying performance of different prediction methods across different benchmarks, highlighting the need for continued development of more versatile and efficient prediction software. Depending on the application, researchers may need to balance performance with execution time when selecting a predictor. Methods based on AlphaFold2 seem to be good ID predictors but they are better at detecting absence of order rather than ID regions as defined in DisProt. The CAID2 predictors can be freely used through the CAID Prediction Portal, and CAID has been integrated into OpenEBench, which will become the official platform for running future CAID challenges

CAID prediction portal: A comprehensive service for predicting intrinsic disorder and binding regions in proteins

Intrinsic disorder (ID) in proteins is well-established in structural biology, with increasing evidence for its involvement in essential biological processes. As measuring dynamic ID behavior experimentally on a large scale remains difficult, scores of published ID predictors have tried to fill this gap. Unfortunately, their heterogeneity makes it difficult to compare performance, confounding biologists wanting to make an informed choice. To address this issue, the Critical Assessment of protein Intrinsic Disorder (CAID) benchmarks predictors for ID and binding regions as a community blind-test in a standardized computing environment. Here we present the CAID Prediction Portal, a web server executing all CAID methods on user-defined sequences. The server generates standardized output and facilitates comparison between methods, producing a consensus prediction highlighting high-confidence ID regions. The website contains extensive documentation explaining the meaning of different CAID statistics and providing a brief description of all methods. Predictor output is visualized in an interactive feature viewer and made available for download in a single table, with the option to recover previous sessions via a private dashboard. The CAID Prediction Portal is a valuable resource for researchers interested in studying ID in proteins. The server is available at the URL: https://caid.idpcentral.org

Devenir du peuplier blanc dans le Nord-Ouest algérien Diagnostic sanitaire de quelques peuplements sur la région de Tlemcen.

Cet article descriptif fait état du dépérissement du peuplier blanc dans la région de Tlemcen en Algérie. Les différentes observations suggèrent le rôle fragilisant du déficit hydrique récurrent. Dans le cadre du réchauffement planétaire actuel, il est plus que jamais indispensable de favoriser l'observation, la surveillance et la mise en place d'actions préventives sur ces peuplements

Platypalpus verbekei Grootaert & Chvala, 1992, nova espècie per Algèria i pel Nord d'Àfrica amb un catàleg de les espècies conegudes d'Algèria de la família Hybotidae (Diptera: Empidoidea: Hybotidae)

Based on the collections made in crop fields in Mostaganem (Algeria), an updated list of the Hybotidae species of Algeria is performed. The species Platypalpus verbekei Grootaert & Chvala, 1992 is here cited for the first time in North Africa. This species has a chromatic variation and a certain clypeus variation respect the European populations which are here detailed. In order to facilitate the recognition of this species it is included in this study a diagnosis (in Catalan) and a redescription (in English) based on the specimens collected from the Algerian population, showing the phenotypic variability of the species present in the two shores of the Mediterranean. In total 27 species distributed in 5 genera are known so far in Algeria, of which 4 are cited only in Algeria. Two species are excluded from the catalogue of the Algerian species giving the reasons for that decisio

First report of branch canker and dieback caused by Cryphonectria naterciae on quercus suber in Algeria

Over the last few decades, severe and widespread tree decline and mortality events have been observed in all the main growing cork oak (Quercus suber L.) forests in Algeria. In winter 2016, during a study on the fungal pathogens involved in the aetiology of cork oak decline, Diplodia corticola was found to be the main causal agent of branch canker and dieback. However, in addition to D. corticola, isolations from five branches showing exudation, sunken canker and dieback symptoms out of 29 trees investigated in the forest of M'sila (35°37'23''N - 0°53'00''O) yielded on potato dextrose agar (PDA) at 25°C orange to red fungal colonies, with a felty and uniform mycelium. Pycnidia were produced within 4 weeks in the centre of colony maintained on the laboratory bench at room temperature under natural daylight. The hyaline, cylindrical to ellipsoid and aseptate conidia were exuded in a yellow to orange gelatinous matrix and measured 2.7-5.6 × 0.9-2.1 μm (n = 50). All morphological characters corresponded to th..
