Does leaf position influence induced resistance to grape downy mildew?
2013
National audience; We observed that protection against grape downy mildew achieved by resistance inducers was higher in the adult leaf than in the younger, not fully expanded leaf. Using sulfated laminarin as inducer, this difference of efficacy could be correlated to stronger defense reactions (i. e. H2O2, defense gene expression) in adult leaf as compared to the younger one. These findings should be taken into account in disease control strategies involving induced resistance.
Target 5G visible light positioning signal subcarrier extraction method using particle swarm optimization algorithm
2021
International audience; With the explosive growth of demand for Internet of Things (IoT) applications and the increasing dependence of users on wireless connections, indoor location based service(LBS) under 5G-Public-Private Partnership (5G-PPP) using cases have received more attention and get rapid development. Thanks to the safty, security and customization of 5G network pointed by 5G forum white paper, indoor positioning systems using unified 5G New Radio (NR) signals have become the focus of the next generation of visible light positioning (VLP) systems. In 5G New Radio(NR) frame, totally 192 subcarriers are used to carry positioning reference signal(PRS). In order to improve the positi…
On improving the accuracy of Visible Light Positioning system using deep autoencoder
2020
International audience; DC-biased optical Orthogonal Frequency DivisionMultiplexing (DCO-OFDM)-based visible light positioning (VLP)technology along with the Received Signal Strength(RSS) po-sitioning algorithm is widely used to achieve centimeter levelpositioning accuracy for incoming 5G era, especially indoorenvironment. However, the DCO-OFDM has the peak-to-averagepower ratio (PAPR) issue which imposes the nonlinear distortionand it will directly affect the positioning accuracy in the VLPsystem. The PAPR reduction scheme is urgently needed. There-fore, in this paper, the impact of PAPR reduction scheme onpositioning accuracy is investigated. The positioning accuracywith and without the s…

Developing Academic Thinking in the EFL Writing Classroom: A Rationale for General-academic Writing Assignments
2020
Ante el evidente y continuo crecimiento de la variación disciplinaria en el discurso académico, la noción de enseñar el pensamiento académico básico por escrito parece haberse vuelto cada vez más controvertida. Este artículo ofrece una justificación para dos tareas de escritura académica general, cada una de las cuales se centra en la enseñanza de un aspecto clave de lo que se define como la postura intelectual subyacente a la redacción académica en general: la problematización y la posición del sujeto. Problematizar y asumir una nueva posición del sujeto en el contexto de la escritura académica suelen ser tareas difíciles para muchos estudiantes cuando ingresan en la universidad. Las tare…
CAROLS: A New Airborne L-Band Radiometer for Ocean Surface and Land Observations
2011
The "Cooperative Airborne Radiometer for Ocean and Land Studies" (CAROLS) L-Band radiometer was designed and built as a copy of the EMIRAD II radiometer constructed by the Technical University of Denmark team. It is a fully polarimetric and direct sampling correlation radiometer. It is installed on board a dedicated French ATR42 research aircraft, in conjunction with other airborne instruments (C-Band scatterometer--STORM, the GOLD-RTR GPS system, the infrared CIMEL radiometer and a visible wavelength camera). Following initial laboratory qualifications, three airborne campaigns involving 21 flights were carried out over South West France, the Valencia site and the Bay of Biscay (Atlantic O…
Nutella vs Pan di Stelle: guerra di affetti, vasetti, biscotti
2020
In questo contributo si esamina un caso di concorrenza tra brand alimentari del mercato italiano, quello tra Ferrero Nutella e Mulino Bianco Pan di Stelle. In particolar modo viene esaminata la strategia di comunicazione da un punto di vista semiotico per il lancio e il posizionamento dei prodotti creme spalmabili e biscotti farciti.
