Mouret, Dubois, and Perissat : the laparoscopic breakthrough in Europe (1987-1988)
No full textIn the late 1980s, laparoscopy was essentially a gynecologist's tool. One of the French private surgeons, Phillipe Mouret of Lyon, shared his surgery practice with a gynecologist and thus had access to both laparoscopic equipment and to patients requiring laparoscopy. In March of 1987, Mouret carried out his first cholecystectomy by means of electronic laparoscopy. Although he never published anything about this experience, the news on his technique reached Francois Dubois of Paris. Although having no prior laparoscopic experience, Dubois acted immediately. He borrowed the instruments from gynecologists, performed his first animal experiments and, in April 1988, carried out the first laparoscopic cholecystectomy (LC) in Paris. Inspired by Dubois, Jacques Perissat of Bordeaux, introduced endoscopic cholecystectomy in his clinic and presented this technique at a SAGES meeting in Louisville in April 1989. Very soon, news of the French work in LC soon swept beyond the country's borders. Dubois and Perissat spoke enthusiastically about their work at the meetings and were largely responsible for establishing what is today called the French technique

ABSTRACT
Learning in robotics typically involves choosing a simple goal
(e.g. walking) and assessing the performance of each con-
troller with regard to this task (e.g. walking speed). How-
ever, learning advanced, input-driven controllers (e.g. walk-
ing in each direction) requires testing each controller on a
large sample of the possible input signals. This costly pro-
cess makes difficult to learn useful low-level controllers in
robotics.
Here we introduce BR-Evolution, a new evolutionary learn-
ing technique that generates a behavioral repertoire by tak-
ing advantage of the candidate solutions that are usually
discarded. Instead of evolving a single, general controller,
BR-evolution thus evolves a collection of simple controllers,
one for each variant of the target behavior; to distinguish
similar controllers, it uses a performance objective that al-
lows it to produce a collection of diverse but high-performing
behaviors. We evaluated this new technique by evolving gait
controllers for a simulated hexapod robot. Results show that
a single run of the EA quickly finds a collection of controllers
that allows the robot to reach each point of the reachable
space. Overall, BR-Evolution opens a new kind of learning
algorithm that simultaneously optimizes all the achievable
behaviors of a robot

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

CONTINUOUS MONITORING OF PHOTOLYSIS PRODUCTS BY THZ SPECTROSCOPY
No full textWe demonstrate the potential of THz spectroscopy to monitor the real time evolution of the gas phase concentration of photolysis products and determine the kinetic reaction rate constantfootnote{H. M. Pickett and T. L. Boyd, Chem. Phys. Lett, Vol 58, 446-449, (1978) }. In the primary work, we have chosen to examine the photolysis of formaldehyde (HCO) footnote{S. Eliet, A. Cuisset, M Guinet, F. Hindle, G. Mouret, R. Bocquet, and J. Demaison, Journal of Molecular Spectroscopy, Vol 279, 12-15 (2012). }. Exposure of HCO to a UVB light (250 to 360 nm) in a single pass of 135 cm length cell leads to decomposition via two mechanisms: the radical channel with production of HCO and the molecular channel with production of CO. A commercial THz source footnote{G. Mouret, M. Guinet, A. Cuisset, L. Croiz, S. Eliet, R. Bocquet and F. Hindle, Sensors Journal. IEEE, Vol 13, 133-138, (2013)} (frequency multiplication chain) operating in the range 600-900 GHz was used to detect and quantify the various chemical species as a function of time. Monitoring the concentrations of CO and HCO via rotational transitions, allowed the kinetic rate of HCO consummation to be obtained, and an estimation of the rate constants for both the molecular and radical photolysis mechanisms.
We have modified our experimental setup to increase the sensitivity of the spectrometer and changed sample preparation protocol specifically to quantify the HCO concentration. Acetaldehyde was used as the precursor for photolysis by UVC resulting in the decompositon mechanism can be described by:
Frequency modulation of the source and Zeeman modulation is used to achieve the high sensitivity required. Particular attention has been paid to the mercury photosensitization effect that allowed us to increase the HCO production enabling quantification of the monitored radical. We quantify the HCO radical and start a spectroscopic study of the line positions.Made available in DSpace on 2016-01-05T20:03:51Z (GMT). No. of bitstreams: 3

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
