This paper describes two different approaches of simulating embedded control software whose real-time requirements are explicitly specified by means of the Logical Execution Time (LET) abstraction introduced in the Giotto project. As simulation environments we chose the black-box MATLAB/Simulink product and the open-source project Ptolemy II. The paper first sketches the modeling of LET-based c...
Donor lymphocyte infusion (DLI), a standard relapse treatment after allogeneic stem cell transplantation (AlloSCT), has limited efficacy and often triggers GVHD. We hypothesized that after AlloSCT tumor-infiltrating donor lymphocytes could be costimulated ex vivo to preferentially activate/expand antitumor effectors. We tested the feasibility and safety of costimulated, tumor-derived donor lymp...
Le trouble développemental du langage (TDL) est une pathologie neurodéveloppementale fréquente (environ 7 % des enfants d’âge préscolaire et scolaire) mais peu connue. Cet article distingue cinq enjeux actuels qui sont importants pour la compréhension prise en charge TDL : 1) considération de spécificité langues multilinguisme, 2) l’importance recourir à l’appellation commune « » suivant les re...
This report describes the challenges in meeting the requirements for optical buffering devices in next -generation optical routers. Slow light and delay line buffering approaches are described and several recent results and issues are summarized.
A single intravenous injection of a relatively small number of T cells contained in the population of rat thoracic duct lymphocytes (TDL) is sufficient to restore to normal the peripheral T cell pool of athymic PVG.rnu/rnu nude rats. The donor T cells expand greater than 10-15-fold, self-renew, and restore immunocompetency to nude recipients permanently (greater than 2 yr). We asked whether the...
Because of the coexistence of multiplex tactical data links (TDLs) it is urgent to study the cooperation of Multi-Net-Multi-Link (MNML) TDL. This paper proposes a Multi-Channel-Multi-MAC (MCMM) model architecture to support MNML TDL simulation. The MCMM model adds several copies of data link layer, network interface and channel which are capable to cover the configurations of multi-channel and ...
We propose a novel method for massive Multiple-Input Multiple-Output (massive MIMO) in Frequency Division Duplexing (FDD) systems. Due to the large frequency separation between Uplink (UL) and Downlink (DL), in FDD systems channel reciprocity does not hold. Hence, in order to provide DL channel state information to the Base Station (BS), closed-loop DL channel probing and feedback is needed. In...
During the last few years, new synchronization techniques to send data between IC’s at increasingly high datarates have been developed. Some of them rely on digital delay lines. The timing accuracy of the delay lines is crucial for a good functionality of the synchronization mechanism. This paper will present a strategy to measure the tap-delays of a digital delay-line, using the well-known osc...
This report compares industrial state-of-the-art products (TTTech, DaVinci and dSPACE) for development of dependable real-time applications with the methodology introduced by Giotto and refined by the Timing Definition Language (TDL). Giotto/TDL aims at a paradigm shift in the development of dependable real-time control systems by focusing on the application rather than on the platform. It repr...
