— This paper presents a feature extraction technique based on the Hilbert-Huang Transform (HHT) method for emotion recognition from physiological signals. Four kinds of physiological signals were used for analysis: electrocardiogram (ECG), elec-tromyogram (EMG), skin conductivity (SC) and respiration changes (RSP). Each signal is decomposed into a finite(More)
The insulin-like growth factor I (IGF-I) receptor (IGF-IR) is known to regulate a variety of cellular processes including cell proliferation, cell survival, cell differentiation, and cell transformation. IRS-1 and Shc, substrates of the IGF-IR, are known to mediate IGF-IR signaling pathways such as those of mitogen-activated protein kinase (MAPK) and(More)
The RAS-ERK pathway is known to play a pivotal role in differentiation, proliferation and tumour progression. Here, we show that Erk downregulates Forkhead box O 3a (FOXO3a) by directly interacting with and phosphorylating FOXO3a at Ser 294, Ser 344 and Ser 425, which consequently promotes cell proliferation and tumorigenesis. The ERK-phosphorylated FOXO3a(More)
This paper deals with emotional speech detection in home movies. In this study , we focus on infant-directed speech also called " motherese " which is characterized by higher pitch , slower tempo , and exaggerated intonation. In this work , we show the robustness of approaches to automatic discrimination between infant-directed speech and normal directed(More)
In this paper, we present an automatic motherese detection system for the study of parent-infant interaction analysis. Motherese is a speech register directed towards infants and it is characterized by higher pitch, slower tempo, and exaggerated intonation. The goal of this paper is to propose and evaluate different approaches for the detection of motherese(More)
Interaction between a T cell receptor (TCR) and various ligands, i.e. , anti-TCR antibodies, superantigens, peptides, or altered peptide ligands in the context of major histocompatibility complex (MHC) molecules can trigger different T helper cell (Th) effector functions. Herein, we studied the T cell response induced by a soluble, dimeric peptide/MHC class(More)
—This paper addresses gait analysis for a mobility assistance robot designed for the elderly people. Six patients and ten healthy peoples were invited to be part of our first pilot experiment. We designed two experiments so as to firstly detect gait parameters and secondly to identify a change of speed. For the first trial, we compared the temporal-distance(More)
In this paper, we propose and experiment a system for human motion capture which can be incorporated into a mobility aid device such as a walker. This measurement system uses two Kinect 3D vision sensors whose data are mapped after treatment on a physical model of virtual human. This filtering method ensures data consistency as well as the observability of(More)
