Structure and evolution of the leucine plasmids carried by the endosymbiont (Buchnera aphidicola) from aphids of the family Aphididae.
1998
In all examined species of the family Aphididae, the bacterial endosymbiont Buchnera aphidicola carries a plasmid encoding the genes leuABCD (involved in leucine biosynthesis) along with repA1, repA2 and ORF1. The gene organisation of the leucine plasmids was conserved, except in Buchnera isolated from Pterocomma populeum, where ORF1 was located in a different position. An inverted repeat (LIR1) located between repA2 and leuA is found in all of the Buchnera leucine plasmids examined. The predicted secondary structure of the LIR1 transcript conforms to a long hairpin loop, suggesting an involvement in transcription termination or messenger stability. Phylogenetic reconstruction based on repA…
Heavy-Ion Radiation Impact on a 4Mb FRAM under Different Test Conditions
2015
The impact of heavy-ions on commercial Ferroelectric Memories (FRAMs) is analyzed. The influence of different test modes (static and dynamic) on this memory is investigated. Static test results show that the memory is prone to temporary effects occurring in the peripheral circuitry. Dynamic tests results show a high sensitivity of this memory to heavy-ions.
Real-Time Temporal Superpixels for Unsupervised Remote Photoplethysmography
2018
International audience; Segmentation is a critical step for many computer vision applications. Among them, the remote photoplethys-mography technique is significantly impacted by the quality of region of interest segmentation. With the heart-rate estimation accuracy, the processing time is obviously a key issue for real-time monitoring. Recent face detection algorithms can perform real-time processing, however for unsupervised algorithms, i.e. without any subject detection based on supervised learning, existing methods are not able to achieve real-time on regular platform. In this paper, we propose a new method to perform real-time un-supervised remote photoplethysmograhy based on efficient…
Knowledge management in cyberphysical systems: determining the quality requirements for health systems with the Kano model
2018
This paper focuses on knowledge management in cyberphysical systems (CPS), dealing with the importance and influence of smart technologies for the creation of the smart health systems as a part of the smart home. This approach considers the reorganisation and adaptation of medicine and health systems, building the research framework upon knowledge management 4.0 for health systems. Customer satisfaction or dissatisfaction was researched using the qualitative methodology of the Kano model. The questionnaire deals with five factors that play a crucial role in the decision to purchase such a system: 1) software reliability; 2) medical device interoperability; 3) security and privacy; 4) system…
Cross-Talk Correction Method for Knee Kinematics in Gait Analysis Using Principal Component Analysis (PCA): A New Proposal
2014
International audience; Background: In 3D gait analysis, the knee joint is usually described by the Eulerian way. It consists in breaking down the motion between the articulating bones of the knee into three rotations around three axes: flexion/extension, abduction/adduction and internal/external rotation. However, the definition of these axes is prone to error, such as the "cross-talk'' effect, due to difficult positioning of anatomical landmarks. This paper proposes a correction method, principal component analysis (PCA), based on an objective kinematic criterion for standardization, in order to improve knee joint kinematic analysis. Methods: The method was applied to the 3D gait data of …
Food loss and waste in food supply chains. A systematic literature review and framework development approach
2021
Abstract This study examines the state of the art of the literature in the domain of food loss and waste (FLW) in food supply chains (FSC). The authors used a systematic literature review (SLR) approach to examine and synthesise the findings of the existing literature to identify the key research themes, research gaps and avenues of future research on FLW in FSC. To this end, this SLR considered 152 articles relevant for the review. The authors uncovered the extant literature in the domain by presenting the research profile of the selected studies, along with thematic analysis. The authors identified eight key themes from the extant literature. The themes range from factors responsible for …
An analysis of co‐operative agreements from a knowledge‐based perspective: an integrative conceptual framework
2002
The last decade has been witness to an unprecedented growth in the number of alliances between companies. This growing importance of interfirm co‐operation, together with its inherent complexity, have generated a progressive interest in the study of this phenomenon, which has materialised in a vast but fragmented literature concerning it. As a response to the demands which these conditions pose, we have endeavoured to develop a conceptual framework which, from a knowledge‐based and learning perspective, integrates an extensive series of contributions and concepts for the study of the processes of co‐operation between companies. As distinctive features, our conceptual framework proposal sets…
A Framework for Small Group Support in Online Collaborative Learning - Combining Collaboration Scripts and Online Tutoring
2017
Many learners experience difficulties engaging in collaborative learning activities online. Computer-supported collaborative learning (CSCL) scripts have been implemented to support online learners. Collaboration scripts have shown much potential in facilitating students’ general collaboration skills. However, reported effects of collaboration scripts on domain-specific knowledge acquisition have been less positive. In this paper, I suggest an alternative framework for supporting CSCL learners by combining collaboration scripting and online tutoring. While collaboration scripts can facilitate the acquisition of general collaboration skills, the online tutor is capable of monitoring and asse…
Integrating Individual and Intra-organizational Learning for Calibration of Organization’s Performance
2021
The pragmatic literature review explores the significance of individual and intra-organizational learning for organization’s performance. Literature review depicts topic actuality, conceptual contribution, research methods and scientific discussions. The relativity of learning for individuals and organization have been evaluated on behalf of selected scientific papers. The articles reviewed for developing literature review have shown similarities of subject knowledge. The comparative analysis of conceptual framework is based on examination of experiments and modelling documented in previous research. Learning is considered as a process of transferring skills and knowledge from recognized in…
Explorando la divulgación de información integrada por universidades colombianas. Un análisis de páginas web basado en el marco del IIRC
2021
La información integrada se presenta como un fenómeno de reciente auge que permite a diversas organizaciones informar de una manera simplificada pero completa sobre su gestión respecto a diversos tipos de capitales. Aunque predominantemente se ha desarrollado en las empresas privadas, en el ámbito internacional viene reconociéndose que otro tipo de organizaciones como las universidades, divulgan esta información o cuentan con la necesidad y el potencial para ello. Este trabajo tiene como objetivo analizar en qué medida la información solicitada para construir un reporte integrado de acuerdo con los requerimientos del Marco Conceptual del IIRC, ya está revelada en internet por las universida…
