Nonlinear Operation of Resonant Sensors Based On Weakly Coupled Resonators: Theory and Modeling.

This theoretical work investigates the properties of nonlinearly operated weakly coupled resonators (WCRs) for resonant sensing applications. We propose an analysis framework for mutually injection-locked oscillators (MILOs) and mode-localized oscillators (MOLOs), subject to nonlinear restoring and damping forces. Under some simplifying assumptions, three sensor architectures are investigated and compared, highlighting several common features, such as: 1) the insensitivity of the amplitude ratio output metric to the A-f effect and 2) the instability of one oscillation state above a threshold amplitude.

Ultimate Limits of Differential Resonant MEMS Sensors Based on Two Coupled Linear Resonators.

In this paper, we investigate how additive noise, e.g., thermomechanical noise, impacts the resolution of mode-localized resonant sensing architectures based on two passively coupled linear resonators.

[Prostatitis and fertility: the biologist's point of view].

There are two leukocytospermia: the leukocytospermia below 10(6) cells/ml comes from the epididymis. It is physiological, improves sperm quality and ART outcomes and therefore must be respected. Leukocytospermia above 10(6) cells/ml are of prostatic origin and reflect a chronic prostatitis.

[ART with sperm donor after intraconjugal ICSI failure].

Objectives: To evaluate the ART results with sperm donation for couples who do not succeed after IC ICSI treatment for male infertility.

Patients And Methods: Retrospective study of 71 couples (November 1994-February 2009). Two control populations were determined to analyse this two-steps treatment (IC and sperm donation) based on different criteria such as the date of ICSI, the female age at the time of the first attempt and the male indication.
