    This paper is focused on analysing the energetic key performance indicators of a hybrid electric bus fleet in order to improve its energy management (at local and fleet level) and profitability. The analysed fleet is composed of buses with parallel and series configurations and include energy storage systems based on batteries and ultra capacitors. The test routes have been selected from a data base of urban standardised cycles. In a first stage, a dynamic programming approach has been applied to determine the initial optimal operation performance for each bus route. Then, several disruptions (e.g. traffic jams, auxiliary consumption and passenger variations) have been added to the routes to simulate "real" road and daily operation conditions. In this paper, a fleet learning methodology is proposed to analyse, process and decide based on the collected data from "real" conditions of the whole fleet. This data is used for monitoring the energetic key performance factors by learning from the buses with the best energetic behaviour. Finally, a decision making process is applied to improve the local energy management of the less-efficient bus.

    Background: Few studies have examined whether childhood asthma/allergies prevented young adults entering jobs with exposure to asthmagens. Aims: To determine whether history of asthma/allergies in childhood was associated with avoidance of exposed jobs in early adulthood. Methods: The Melbourne Atopic Cohort Study recruited 620 children at high risk of allergic diseases at birth (1990-94). Asthma, hay fever and eczema were evaluated by questionnaires at ages 6-7 and 12 years. A follow-up in early adulthood (mean age: 18 years) collected information on the current job. Occupational exposure to asthmagens was evaluated by a revised asthma specific job-exposure-matrix. The association between history of asthma/allergies in childhood and working in a job with exposure to asthmagens (vs. not working or non-exposed job) was evaluated by logistic regression, adjusted for age, sex and parental education. Results: Among 363 participants followed-up until early adulthood, 17% worked in a job with exposure to asthmagens. History of asthma (35%) was not associated with working in an exposed job (adjusted OR: 1.16, 95%CI: 0.65-2.09). Subjects with history of hay fever (37%) and eczema (40%) were more likely to enter exposed jobs (significant for hay fever: 1.87, 1.05-3.33; but not eczema: 1.65, 0.93-2.93). The association for hay fever was more pronounced in those with less parental education (2.97, 1.06-8.38; p for interaction: p=0.24). Conclusion: In this Australian cohort, young adults with history of allergies were more likely to enter exposed jobs, suggesting no asthmagen avoidance. Improved counseling against high risk jobs may be needed for young adults with these conditions.

    International audience; At present, molecular communications has largely been studied in isolation; that is, without the presence of any external biological systems. However, for applications in nanomedicine and advanced manufacturing, this assumption of isolation is unlikely to always hold. A key question is therefore how to design signaling strategies such that the desired information can be communicated, while not disrupting the function of the external biological system. In this paper, we study this problem by establishing a coexistence constraint based on the Kullback-Leibler divergence between the distribution of molecules on the surface of the biological system, with and without the presence of the molecular communication system. We then address the problem of how the transmitting device can estimate these distributions from local observations of its environment. Based on this, we optimize the modulation scheme used by the transmitter subject to the coexistence constraint. Trade-offs between the coexistence constraint, the probability of error, and the number of samples used to estimate distributions needed to compute the coexistence constraint are then studied numerically.

    Long term sustainability of the high energy physics (HEP) research software ecosystem is essential for the field. With upgrades and new facilities coming online throughout the 2020s this will only become increasingly relevant throughout this decade. Meeting this sustainability challenge requires a workforce with a combination of HEP domain knowledge and advanced software skills. The required software skills fall into three broad groups. The first is fundamental and generic software engineering (e.g. Unix, version control,C++, continuous integration). The second is knowledge of domain specific HEP packages and practices (e.g., the ROOT data format and analysis framework). The third is more advanced knowledge involving more specialized techniques. These include parallel programming, machine learning and data science tools, and techniques to preserve software projects at all scales. This paper dis-cusses the collective software training program in HEP and its activities led by the HEP Software Foundation (HSF) and the Institute for Research and Innovation in Software in HEP (IRIS-HEP). The program equips participants with an array of software skills that serve as ingredients from which solutions to the computing challenges of HEP can be formed. Beyond serving the community by ensuring that members are able to pursue research goals, this program serves individuals by providing intellectual capital and transferable skills that are becoming increasingly important to careers in the realm of software and computing, whether inside or outside HEP Comment: For CHEP 2021 conference,sent for publication to CSBS Springer

    Vibration is a promising way to intensify the drying process through heating-up due to viscous dissipation, activation of internal liquid transfer and increase of external transfer. To better assess the possible contribution of these effects, we choose a multiscale approach. This paper is focused on the pore scale, simulated by a capillary tube partially filled with water subjected to sinusoidal vibrations. We studied the displacement of water inside this tube through image analysis. This configuration mimics the moisture transfer inside the pores of a porous media during drying. The experimental device developed in this study is applicable to a wide range of configurations, such as symmetrical or asymmetrical vibrations. Keywords: drying intensification, acoustic vibration, pore scale, symmetrical and asymmetrical signals, image processing.

    This paper presents a control law for the trajectory tracking of mobile robots under slip conditions and subject to both system constraints and varying dynamics. First, a control law is obtained based on a Lyapunov function to guarantee closed-loop asymptotic stability, resulting in a set of feedback gains, one for each extreme model realization. On-line computation is devoted to determine an adaptive feedback control law for the current realization of the state as a convex combination of the gains previously obtained. Simulations comparing the proposed control law with other strategies under slip conditions are provided. They show the satisfactory behavior of the proposed control strategy.

    International audience; Orchestras of Digital Musical Instruments (DMIs) enable new musical collaboration possibilities, extending those of acoustic and electric orchestras. However the creation and development of these orchestras remain constrained. In fact, each new musical collaboration system or orchestra piece relies on a fixed number of musicians, a fixed set of instruments (often only one), and a fixed subset of possible modes of collaboration. In this paper, we describe a unified framework that enables the design of Digital Orchestras with potentially different DMIs and an expand-able set of collaboration modes. It relies on research done on analysis and classification of traditional and digital orchestras, on research in Collaborative Virtual Environments, and on interviews of musicians and composers. The BOEUF framework consists of a classification of modes of collaboration and a set of components for modelling digital orchestras. Integrating this framework into DMIs will enable advanced musical collaboration modes to be used in any digital orchestra, including spontaneous jam sessions.

    International audience; Les variations communes de séquence d’ADN existantes chez l’Homme modifient l’expression des gènes et contribuent à la susceptibilité aux maladies complexes. Notre objectif est d’établir la relation entre le contrôle transcriptionel du tissu adipeux blanc et la susceptibilité à l’adiposité et au diabète mis en évidence chez le rat spontanément diabétique de la souche Goto-Kakizaki (GK). En utilisant des puces à ADN Illumina, nous avons analysé l’expression d’environ 20,000 gènes dans le tissu adipeux blanc d’une population F2 (n = 138) derivée du GK et du rat contrôle Brown-Norway (BN) et d’une lignée congénique portant sur un fond génétique BN, les allèles GK à un locus génetique (QTL) lié à l’adiposité. Les loci liés à l’expression des gènes (eQTL) ont été identifiés dans la population F2 en utilisant R/QTL, validés dans la lignée congénique par qRT-PCR, et analysés en relation avec la séquence génomique du GK produite au laboratoire. Nous avons identifié sur le génome entier, 585 eQTLs statistiquement significatifs (LOD > 9). La région 1q33 (8,3Mb), qui coségrège avec un QTL d’adiposité, contient 172 gènes candidats positionnels, parmi lesquels 44 correspondent à un eQTL. Nous avons validé l’expression différentielle de 27 de ces 44 gènes dans la lignée congénique, qui montrent pour 48 % d’entre eux un effet de régulation transcriptionnelle en cis. L’analyse de 20,000 polymorphismes SNPs présents dans la région 1q33 nous a permis d’éliminer les eQTLs faux positifs et d’entreprendre l’analyse fonctionnelle de polymorphismes localisés sur les gènes candidats positionnels du QTL lié à l’adiposité, parmi lesquels le facteur de transcription ASCL3 (LOD > 43). L’utilisation combinée de données du transcriptome et de séquençage nous a permis d’élucider le contrôle transcriptionnel du tissu adipeux blanc chez un modèle de diabète et d’identifier des gènes candidats fonctionnels et positionnels au locus1q33 associé à l’adiposité chez le rat GK.

    International audience; The main objective of this activity is to develop new focal plane coupling array concepts and technologies thatoptimise the coupling from reflector optics to the large number of detectors for next generation sub millimetrewave telescopes particularly targeting measurement of the polarization of the cosmic microwave background(CMB). In this 18 month TRP programme the consortium are tasked with developing, manufacturing andexperimentally verifying a prototype multichroic pixel which would be suitable for the large focal plane arrayswhich will be demanded to reach the required sensitivity of future CMB polarization missions. One majordevelopment was to have multichroic operation to potentially reduce the required focal plane size of a CMBmission. After research in the optimum telescope design and definition of requirements based on a stringentscience case review, a number of compact focal plane architecture concepts were investigated before a pixeldemonstrator consisting of a planar mesh lens feeding a backend Resonant Cold Electron Bolometer RCEB forfiltering and detection of the dual frequency signal was planned for manufacture and test. In this demonstratorthe frequencies of the channels was chosen to be 75 and 105 GHz in the w band close to the peak CMB signal.In the next year the prototype breadboards will be developed to test the beams produced by the manufacturedflat lenses fed by a variety of antenna configurations and the spectral response of the RCEBs will also beverified.© (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
