CASS & ReSMiQ Innovation Day – RID2015
You are invited to participate in this annual event to be held on October 15th at Polytechnique Montréal. For this 4th edition, ReSMiQ join forces with IEEE Circuits and Systems Society (CASS) to lead this important event. This activity is organized by our center with a complementary financial support of the IEEE CASS to provide visibility to the research work of students from the province of Quebec in the field of microsystems. Both undergraduate and graduate students will demonstrate their scientific and technical expertise through a life demonstration contest before a panel of recognized experts. The three best projects in each category will be awarded cash money and certifcates. The call for projects generated many submissions that resulted in the selection of 13 projects, counting 5 from undergraduate students and 8 from graduate students. RID 2015 will also be an excelent opportunity to attend keynote presentations by three renown speakers who are Viktor Gruev, from University of Washington, Andreas G. Andreou, from John Hopkins University and Giancula Setti, from University of Ferrara in Italy. We thank all of the students who submitted their project. We invite you to regularly visit our web portal for more details. Call for project and preliminary program

The 17th Canadian Semiconductor Science and Technology Conference (CSSTC)
The 17th Canadian Conference on science and semiconductor technologies (CSSTC) was held in Sherbrooke, from August 16 to 21, 2015. Initiated in 1982, this conference covers many subjects such as materials, devices and applications. It allowed this community to network around topics of interest such as the manufacture of micromechanical devices and microelectronics, from nano and biotechnologies to the detectors used in medical imaging. The 138 participants, including 62 students, assisted at 3 plenary sessions, 14 invited presentations, 13 oral presentations, 40 posters, and 8 tutorials. These participants came from Canada, China, the US, France, and Germany. Visits were organized at C2MI and 3IT. The ReSMiQ sponsored the awards for best student presentations. Steffi Woo, from McMaster University, was awarded 1st place for its presentation entitled “Spontaneous Formation of Atomic Ordering in InGaN Alloys Nanowire Heterostructures Within”; Oleksandr Bubon, from Lakehead University, was awarded 2nd place for his presentation entitled “Measured Electron-Hole Pairs in Amorphous Selenium Energy Creation (a-Se) at High Electric Fields using Pulsed-Height Spectroscopy Method”; Gabriel Droulers, from the Université de Sherbrooke was awarded 3rd place for his presentation entitled “Planar Tunnel Junctions: A Time Stability Study”. Réjean Fontaine and Luc Fréchette, from the Université de Sherbrooke and members of ReSMiQ, were in the organizing committee of the conference in charge of the student awards.

The 9th NAMIS international summer school
The 9th NAMIS graduate school was held from 29 June to 3 July 2015 at Polytechnique Montréal. It hosted more than 50 participants from 9 countries and more than 20 speakers. The mornings were devoted to lectures on microsystems covering subjects in the fields of materials, energy, microfabrication processes, optics, biomedical applications, and electronics. The afternoons were dedicated to poster sessions, flash presentations, hands-on workshops, as well as a team competition and laboratory visits. On monday evening, a welcome reception was held at Polytechnique Montréal and a dinner barbecue was held on Wednesday night. Thursday evening, all participants were able to attend the Montreal Jazz Festival.

The 4th golf tournament of the Quebec electronic industry
On June 18th the Table de concertation de l’industrie des systèmes électronique du Québec (CISEQ, RIE, C2MI, AMEQ, CIMEQ et ReSMiQ) organized the 4th edition of its annual golf tournament. During this activity, industry representatives perform a life demonstration of a new and innovative product. Participants attended to the presentation of recent innovations such as the Jaco Kinova articulated arm, and the biometric and smart clothing by OM Signal. The day ended with a golf tournament during which people in the industry met in an atmosphere of relaxation and conviviality. ReSMiQ was represented by Prof. Daniel Massicotte and the industry liaison representative Louis Bélanger.

Joint estimation of states and parameters of Hodgkin–Huxley neuronal model using Kalman filtering

Fitting biophysical models to real noisy data jointly with extracting fundamental biophysical parameters has recently stimulated tremendous studies in computational neuroscience. Hodgkin–Huxley (HH) neuronal model has been considered as the most detailed biophysical model for representing the dynamical behavior of the spiking neurons. The unscented Kalman filter (UKF) has been already applied to track the dynamics of the HH model. In this paper, we extend the existing Kalman filtering (KF) technique for the HH model to another version, namely, extended Kalman filtering (EKF). Two estimation strategies of the KF, dual and joint estimation strategies, are derived for simultaneously tracking the hidden dynamics and estimating the unknown parameters of a single neuron, leading to four KF algorithms, namely, joint UKF (JUKF), dual UKF (DUKF), joint EKF (JEKF) and dual EKF (DEKF) (see Fig. 1). Detailed derivations of these four methods and intensive simulation studies are provided. Our main contribution is in the derivation of the EKF-based methods, JEKF and DEKF, for tracking the states and estimating the parameters of the HH neuronal model. Since these EKF-based methods are faster than UKF-based versions, they can particularly be employed in dynamic clamp technique, which connects artificial and biological neurons in order to assess the function of neuronal circuits.

Fig. 1. Tracking the dynamics of HH neuron model using (A) JUKF, (B) DUKF, (C) JEKF and (D) DEKF. For each method, voltage V, n, m, h, gNa, gK and gL are drawn. Black solid and red dashed lines indicate the true (original) and the estimated values. The observation noise standard deviation is σ=21.81 mV (SNR=0 dB). From these results it is clear that the intracellular voltage (v), the hidden states (m, n and h) and the unknown parameters (gNa, gK and gL) have been reconstructed with excellent accuracy from the noisy observation.
