Phase II study of pemetrexed and cisplatin plus cetuximab followed by pemetrexed and cetuximab maintenance therapy in patients with advanced nonsquam…

2013

Abstract Objectives The aim was to determine if combined pemetrexed, cisplatin, and cetuximab was efficacious and safe as first-line treatment in advanced nonsquamous non-small cell lung cancer (NSCLC). Patients and methods In this single-arm, multicenter clinical trial, patients with Stage IIIB/IV nonsquamous NSCLC received first-line therapy consisting of pemetrexed (500mg/m 2 ) and cisplatin (75mg/m 2 ) on Day 1 (21-day cycles) plus weekly cetuximab (400mg/m 2 loading dose, then 250mg/m 2 ) for 4–6 cycles. Non-progressing patients received maintenance therapy consisting of pemetrexed and cetuximab as above until disease progression. All patients received vitamin supplementation, dexameth…

Hierarchical Syntactic Models for Human Activity Recognition through Mobility Traces

2019

AbstractRecognizing users’ daily life activities without disrupting their lifestyle is a key functionality to enable a broad variety of advanced services for a Smart City, from energy-efficient management of urban spaces to mobility optimization. In this paper, we propose a novel method for human activity recognition from a collection of outdoor mobility traces acquired through wearable devices. Our method exploits the regularities naturally present in human mobility patterns to construct syntactic models in the form of finite state automata, thanks to an approach known asgrammatical inference. We also introduce a measure ofsimilaritythat accounts for the intrinsic hierarchical nature of su…

Crosstalk of regulatory T cells and tolerogenic dendritic cells prevents contact allergy in subjects with low zone tolerance

2012

Background Allergic contact dermatitis is one of the most common occupational diseases. A main protective mechanism in those who do not develop allergic contact dermatitis is tolerance induction by repeated exposure to low doses of contact allergen, which is termed low zone tolerance (LZT). The mechanisms that determine the tolerance induction in subjects with LZT are still elusive. Objective We performed analysis of the role of CD4 + CD25 + forkhead box protein 3 (FOXP3)–positive regulatory T (Treg) cells and dendritic cells (DCs) in mice with LZT. Methods Mechanisms of tolerance induction were analyzed in a murine model of LZT by using FOXP3 and IL-10 reporter mice, as well as mice that a…

A fully-automated procedure for measuring the electrical parameters of an induction motor drive with rotor at standstill

2003

The paper presents an automatic procedure to measure at standstill the electrical parameters of an induction motor fed by a PWM voltage source inverter. The proposed procedure executes automatically three tests using only the available PWM inverter control technique to obtain the required motor supply voltages. It allows the measurement of all the T-form circuit electrical parameters starting from the nameplate data as data-entry. It uses only a current sensor and no voltage sensor and process on line the collected data samples with a fast and easy to implement recursive least squares algorithm. Effectiveness of the automated procedure has been proved both by simulation and experimental tes…

Sensorless Control of Induction-Motor Drive Based on Robust Kalman Filter and Adaptive Speed Estimation

2014

This paper deals with robust estimation of rotor flux and speed for sensorless control of motion control systems with an induction motor. Instead of using sixth-order extended Kalman filters (EKFs), rotor flux is estimated by means of a fourth-order descriptor-type robust KF, which explicitly takes into account motor parameter uncertainties, whereas the speed is estimated using a recursive least squares algorithm starting from the knowledge of the rotor flux itself. It is shown that the descriptor-type structure allows for a direct translation of parameter uncertainties into variations of the coefficients appearing in the model, and this improves the degree of robustness of the estimates. E…

Changing Induced Moods Via Virtual Reality

2006

Mood Induction Procedures (MIPs) are designed to induce emotional changes in experimental subjects in a controlled way, manipulating variables inside the laboratory. The induced mood should be an experimental analogue of the mood that would occur in a certain natural situation. Our team has developed an MIP using VR (VR-MIP) in order to induce different moods (sadness, happiness, anxiety and relaxation). The virtual environment is a park, which changes according to the mood to be induced. This work will present data about the efficacy of this procedure not only to induce a mood, but also to change after the mood is induced.

Can changes in starch content and peroxidase activity be used as rooting phase markers for rhododendron leaf bud cuttings?

2011

We examined whether peroxidase activity in cutting bases and leaves and starch content in cutting bases can be used as rooting phase markers in the elepidote rhododendron cv. 'Babites Baltais' (Rhododendron L.). Changes in peroxidase activity in cutting leaves and bases, as well as starch content in cutting bases, were determined in relation to anatomical stages of rhizogenesis in leaf bud cuttings treated with 1% indole-3-butyric acid (IBA+) or without IBA (IBA–). The pattern of change of peroxidase activity was similar in cutting bases and leaves of IBAleaf bud cuttings. Three phases of adventitious root formation were identified: induction, initiation and expression. During the induction…

Low-cost motion control solution for industrial manufacturing systems

2011

This paperwork deals with a low-cost actuation solution, based upon induction motors, which was seldom used in the motion control systems, especially for the machine tools feed drives. A simulation approach, based upon a mathematical model of the induction motor, for tuning the controllers of the systems is presented. Experimental researches developed upon a two axes motion control system, both axes being driven by alternating current asynchronous motors were also performed in order to test the proposed strategies. The asynchronous motors, used as actuation devices were equipped with incremental rotary encoders and controlled by vector frequency inverters and DSP motion control cards were u…

Contribution à une nouvelle économie de la santé : asymétries d'information et régulation en médecine ambulatoire

1991

Le fonctionnement de la médecine ambulatoire est analysé à travers la spécification de relations d'agence complexes qui s'instaurent entre les différents acteurs : le malade, le médecin, l'assurance, la tutelle. Après une approche conceptuelle et normative qui distingue relations d'agence "parfaites" et "imparfaites", l'accent est mis deux relations : la relation assurance-principal et assuré-agent sur le marché de l'assurance maladie, et la relation patient-principal et médecin-agent sur le marché des soins médicaux. Les "effets pervers" inhérents à l'asymétrie d'information sont étudiés en terme de sélection adverse et de risque moral. L'hypothèse d'une démarche induite par l'offre, consé…
