This paper presents the design, fabrication and preliminary characterization of highly sensitive MEMS-based Xylophone Bar Magnetometers (XBMs) realized in imec’s poly-SiGe MEMS technology. Key for our Lorentz force driven capacitively sensed resonant sensor are the combination of reasonably high Q-factor and conductivity of imec’s poly-SiGe, our optimized multiphysics sensor design targeting the maximization of the Q-factor in a wide temperature range as well as our proprietary monolithic above-CMOS integration and packaging schemes. Prototypes 3-axis devices were fabricated and characterized. We present optical vibrometer and electrical S-parameter measurements of XBMs performed in vacuum with a reference magnet at increasing sensor separation. The optical oscillation amplitude is well correlated with the magnetic field amplitude. The electrical 2-port measurements, 1st port as Lorentz force actuator and 2nd port as capacitive sensor, also reproduces the designed magnetic field dependence. This opens the way towards the on-chip integration of small footprint extremely sensitive magnetometers. [less ▲]

This study is concerning the resilience related a juvenile delinquency among victims of sexual abuse: sexual abuse has been recognized as a powerful risk factor for the emergence of deviant and criminal.behavior. Our study aims is to explore and highlight the protective factors that prevents victims of sexual abuse to engage in delinquent trajectory. The sample consists of teenage girls who have revealed at minimum last year, their intergenerational abuse position. These girls, are all between 12 and 18 years old,and divided into sub-groups: victims not offenders and victims offenders (self revealed and judicial control). Each teenage victims is compared to a normative population on different psychological’s functioning dimensions (aggression, self-esteem and pubertal timing). A comparative analysis between victims and not offenders is conducted to determine the elements that have a protective role. Clinical tests also are performed and linked to data from comparative analysis. The main factors of resilience (compared to a juvenile delinquency commitment) highlights concern the individual, the family system and the natural environment. [less ▲]
