International Consensus Statement on Rhinology and Allergy: Rhinosinusitis
Background: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods: ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion: This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS
Digital Twin and Product Lifecycle Management: What Is the Difference?
Part 2: Digital TwinsInternational audienceWith the rapid development of modern information and communication technologies as well as infrastructure, the digital twin approach becomes increasingly popular and widely used throughout the industry and research. The digital twin is considered to be the key technology to realize the comprehensive digital description of components, products and systems including the information from all lifecycle phases. The Product Lifecycle Management (PLM) strategy has been present in the industry for many years and is considered as the most effective way of managing the components, products and systems of a company all the way across their lifecycles from the first idea of the product to its disposal. The digital twin is not yet clearly defined. It can be defined as a set of models, linked with each other as well as with the physical product enabling data storage and real-time processing. In contrast to a digital twin the PLM strategy provides a framework, which serves as single source of truth connecting the partial models, that describe the physical product. The models can receive the data stored in a product data management system (PDM).The aim of the present paper is to distinguish the characteristics of the digital twin and PLM as well to find similarities and differences in the both approaches. The current development of both strategies is presented, and the answer to the question, where is the difference between digital twin and PLM is given
The added value of spatially distributed meteorological data for simulating hydrological processes in a small Mediterranean catchment
The purpose of this paper was to demonstrate the added value of the spatial distribution of rainfall and potential evapotranspiration (PE) in the prediction of the discharge for a small Mediterranean catchment located in the Medjerda basin in Tunisia, i.e. the Raghay. We compare therefore the performance of a conceptual hydrological model available in the ATHYS platform, using global and spatial distributed input data. The model was implemented in two different ways. The first implementation was in a spatially distributed mode, and the second one was in a non-distributed lumped mode by using spatially averaged data weighed with a Thiessen-interpolated factor. The performance of the model was analysed for the distributed mode and for the lumped mode with a cross-validation test and through several modelling evaluation criteria. Simultaneously, the impact of the spatial distribution of meteorological data was assessed for the two cases when estimating the model parameters, the flow and water amounts, and the flow duration curves. The cross-validation of the split-sample test shows a preference for the spatially distributed model based on accuracy criteria and graphical comparison. The distributed mode required, however, more simulation time. Finally, the results reported for the Raghay indicated that the added value of the spatial distribution of rainfall and PE is not constant for the whole series of data, depending on the spatial and temporal variability of climate data over the catchment that should be assessed prior to the modelling implementations

Sliding Presentation of the Jeux de Taquin for Classical Lie Groups
International audienceThe simple -modules are described by using semistandard Young tableaux. Any semistandard skew tableau can be transformed into a well defined semistandard tableau by a combinatorial operation, the Schützenberger jeu de taquin. Associated to the classical Lie groups , , there are other notions of semistandard Young tableaux and jeux de taquin. In this paper, we study these various jeux de taquin, proving that each of them has a simple and explicit formulation as a step-by-step sliding. Any of these jeux de taquin is the restriction of the orthogonal one, associated to
