Corps, genre et nouvelles technologies biomédicales : reconfigurations antinaturalistes au sein des théories féministes
The biological materiality of the human body has become an object of unprecedented interventions through ânew biomedical technologiesâ as medically assisted procreation, genetic tests, or hormonal contraception. This thesis interrogates the difficulties inherent to anti-naturalist approaches in order to address the biological dimension of sexed bodies. âOne is not born a woman, one becomes oneâ, but is this also true for the body? The analytical frames of materialist or deconstructivist feminism cannot cease the modalities through which biomedical technologies invest the flesh. Do biomedical technologies make constructivist approaches obsolete through the revenge of a biological â hormonal, genetic, molecular â ground that tops the anatomical effects of socialization? Partisans of a feminist âmaterial turnâ seem to think so. After analyzing how the molecular biology revolution changes the very concept of nature in defining it as âlife itselfâ, I offer an alternative interpretation by defining biomedical technologies as technologies of power that stem from a molecular biopolitics of gender. Instead of overturning constructivist perspectives, these new social mediations (residing on a new epistemic paradigm) help understanding a shift in what has been seen as the limits of gender. This shift creates unprecedented identities, experiences and subjectivities of gender. In exposing the coordinates of the biomedical apparatus, this comparative study between disciplinary techniques and molecular biopolitics of gender pleads for a renewed anti-naturalist critique that takes the form of a critique of technology in order to allow for a collective appropriation of biomedical technologies.La matĂ©rialitĂ© biologique du corps humain est devenue l'objet d'interventions inĂ©dites au moyen de nouvelles technologies biomĂ©dicales, comme la procrĂ©ation mĂ©dicalement assistĂ©e, les tests gĂ©nĂ©tiques, la contraception hormonale. Cette thĂšse part des difficultĂ©s inhĂ©rentes Ă une approche antinaturaliste pour aborder la dimension biologique des corps sexuĂ©s. âOn ne naĂźt pas femme, on le devientâ : mais qu'en est-il des corps ? Les technologies biomĂ©dicales investissent la chair selon des modalitĂ©s qui Ă©chappent aux grilles d'analyses matĂ©rialiste et butlĂ©rienne. Faut-il y voir une rĂ©futation du constructivisme, la revanche d'un socle biologique â hormonal, gĂ©nĂ©tique, molĂ©culaire â primant sur les effets anatomiques de la socialisation, comme le suggĂšrent les partisan·e·s d'un material turn fĂ©ministe ? Ă partir d'une analyse de l'Ă©volution de la notion de nature, dĂ©finie comme "vie elle-mĂȘme" depuis la rĂ©volution molĂ©culaire de la biologie, cette thĂšse propose une autre interprĂ©tation, en dĂ©finissant les technologies biomĂ©dicales comme des technologies de pouvoir relevant dâune biopolitique molĂ©culaire de genre. Sans infirmer la perspective constructiviste, ces mĂ©diations sociales originales (adossĂ©es au nouveau paradigme Ă©pistĂ©mique) permettent de comprendre comment les frontiĂšres et limites du genre sont dĂ©placĂ©es, tout en produisant des identitĂ©s, des expĂ©riences et des subjectivitĂ©s genrĂ©es inĂ©dites. En dĂ©gageant les coordonnĂ©es d'un vĂ©ritable dispositif biomĂ©dical, notre Ă©tude comparative entre techniques disciplinaires et biopolitique molĂ©culaire de genre plaide pour une critique antinaturaliste renouvelĂ©e, sâarticulant Ă une critique de la technique qui permette d'inventer collectivement des moyens pour se rĂ©approprier dĂ©mocratiquement les technologies biomĂ©dicales

An adaptive observer-based controller design for active damping of a DC network with a constant power load
This article explores a nonlinear, adaptive controller aimed at increasing the stability margin of a direct-current (dc), small-scale, electrical network containing an unknown constant power load (CPL). Due to its negative incremental impedance, this load reduces the effective damping of the network, which may lead to voltage oscillations and even to voltage collapse. To overcome this drawback, we consider the incorporation of a controlled dc-dc power converter in parallel with the CPL. The design of the control law for the converter is particularly challenging due to the existence of unmeasured states and unknown parameters. We propose a standard input-output linearization stage, to which a suitably tailored adaptive observer is added. The good performance of the controller is validated through experiments on a small-scale network

The data provided in this data set includes all the raw data collected during the characterization of Mo:TiO2 films: raw data of X-Ray photoelectron spectroscopy (XPS), Electrochemically active surface area (ECSA), X-Ray Diffraction, Raman spectroscopy, Electron Paramagnetic Resonance (EPR), UV-Vis spectroscopy, PhotocurrentâPotential curves (J-V), PhotocurrentâTime (J-t), Nyquist plots, IPCE (Incident photon-to-current efficiency) and Faradaic efficiency.See document attached for specific details of the data collection method.The data, with the exception of the EPR data, are presented as tab-separated value (TSV) files. The convention used for the headings of the columns is Mo:TiO2-XXX where XXX is the annealing temperature employed during the preparation of the samples (as described in the experimental section of the manuscript).
The detailed convention method used for each technique, with the corresponding units, is as follows:

Corticotropinâreleasing hormoneâinduced seizures in infant rats originate in the amygdala
The neuroanatomical substrate of seizures induced by picomolar amounts of corticotropinâreleasing hormone in infant rats was investigated. Electrographic and behavioral phenomena were monitored in 42 rat pups aged 5 to 22 days. Rat pups carried bipolar electrodes implanted in subcortical limbic structures, as well as cortical electrodes and intracerebroventricular cannulae. The administration of corticotropinâreleasing hormone produced ageâspecific seizures within minutes, which correlated with rhythmic amygdala discharges. Paroxysmal hippocampal and cortical discharges developed subsequently in some rats. Corticotropinâreleasing hormoneâinduced electrographic and behavioral seizures originate in the amygdala.

Meta-analysis of Androgen Insensitivity in Preoperative Hormone Therapy in Hypospadias.
OBJECTIVE: To define androgen insensitivity prevalence in hypospadias patients treated with preoperative hormone therapy. MATERIALS AND METHODS: We searched databases that were published in English and Chinese up to September 10, 2014 for our studies. Eligibility criteria were pre-established. Title, abstract, and full-text screenings were conducted by 2 authors independently. Discrepancies were resolved by consensus. Quality assessment of included studies was completed. Meta-analysis was done when appropriate using R, version 3.1.1 for Windows. Heterogeneity among individual studies was tested using the Cochran chi-square Q test and quantified by calculating the I(2) index. RESULTS: Thirteen of 1278 publications met inclusion criteria and were incorporated into this study. Of 306 patients with preoperative hormone therapy, 25 displayed androgen resistance. Meta-analysis demonstrated that the random-effects model generates a pooled estimate of 7.14% (95% confidence interval [CI], 3.16%-15.31%), whereas the fixed-effect model provides an estimate of 14.61% (95% CI, 10.00%-20.85%). Heterogeneity among included studies was found above medium (I(2) = 67.1% [95% CI, 41.2%-81.6%]; P = .0003]. After exclusion of the heterogeneity, both random-effects and fixed-effect models produce a consistent pooled estimate of 6.95% (95% CI, 0%-47.8%). CONCLUSION: We have defined that the prevalence of androgen resistance in hypospadias is 7.14% (95% CI, 3.16%-15.31%). To distinguish isolated hypospadias from patients with androgen insensitivity syndrome, we recommend that androgen-resistant patients should be specifically targeted by molecularly focused diagnosis. Management strategies should include identification of mutations in the androgen receptor gene, timely surgery to repair hypospadias, and long-term follow-up of sexual function and fertility later in life
