Détermination de l'âge des moutons Djallonké du Nord de la Côte d'Ivoire par examen de leur dentition
A partir de 852 observations faites sur des moutons Djallonké entretenus en élevage semi-intensif, dont l'âge était connu avec précision, les auteurs ont étudié la dynamique du remplacement des incisives de lait dans le but d'établir des normes d'âge en fonction de l'état de la table dentaire. Les âges moyens à l'éruption des incisives définitives ainsi que la durée de chaque stade dentaire ont été estimés. Les normes suivantes ont été tirées de ces observations. Elles montrent que les Djallonké sont plus précoces que les races européennes. Cette table doit être utilisée avec précaution pour les Djallonké en élevage villageois traditionnel qui paraissent être moins précoces que ceux entretenus en élevage intensif ou semi-intensi
Reduction of Magnetic Noise in Atom Chips by Material Optimization
We discuss the contribution of the material type in metal wires to the
electromagnetic fluctuations in magnetic microtraps close to the surface of an
atom chip. We show that significant reduction of the magnetic noise can be
achieved by replacing the pure noble metal wires with their dilute alloys. The
alloy composition provides an additional degree of freedom which enables a
controlled reduction of both magnetic noise and resistivity if the atom chip is
cooled. In addition, we provide a careful re-analysis of the magnetically
induced trap loss observed by Yu-Ju Lin et al. [Phys. Rev. Lett. 92, 050404
(2004)] and find good agreement with an improved theory.Comment: 25 pages with 9 figures ep

Closure Discovery for Coarse-Grained Partial Differential Equations Using Grid-based Reinforcement Learning
Reliable predictions of critical phenomena, such as weather, wildfires and
epidemics often rely on models described by Partial Differential Equations
(PDEs). However, simulations that capture the full range of spatio-temporal
scales described by such PDEs are often prohibitively expensive. Consequently,
coarse-grained simulations are usually deployed that adopt various heuristics
and empirical closure terms to account for the missing information. We propose
a novel and systematic approach for identifying closures in under-resolved PDEs
using grid-based Reinforcement Learning. This formulation incorporates
inductive bias and exploits locality by deploying a central policy represented
efficiently by a Fully Convolutional Network (FCN). We demonstrate the
capabilities and limitations of our framework through numerical solutions of
the advection equation and the Burgers' equation. Our results show accurate
predictions for in- and out-of-distribution test cases as well as a significant
speedup compared to resolving all scales.Comment: 23 pages, 12 figure
Centro parroquial Harksheide-Stüberg Alemania Federal
The Centre of the Evangelic Lutheran Community in Harksheide-Stüberg, situated in the midst of spacious green lawns, consists of two independent constructions with a central open patio in between, where the entrances to the social gathering premises are located.
The smallest building, one storey only, is designed for the kindergarten. It comprises: three meeting rooms for groups, play room, office for the director, and housing for the person in charge of the kindergarten, washrooms and kitchen.
The other two-storeyed building is entirely planned for the grown-up community, containing on the ground-floor: chapel, club for retired people, meeting room and a room for games, administration department and the dúplex housing for the parson. On the top floor are distributed: library, room for religious teaching, offices and two houses - one for the sacristan and the other one for the deaconess.
In the construction traditional systems and materials have been used, and whenever possible the natural surfaces have been maintained. In this manner, a pleasant contrast of textures and colours has been achieved, as well as great simplicity in the lines, in perfect harmony with the country side setting.El Centro de la Comunidad Evangélica Luterana de Harkseide-Stüberg, ubicado en un lugar rodeado de amplias praderas, está constituido por dos construcciones independientes que crean entre sí un patio central abierto, en donde se sitúan las entradas a los locales sociales.
El edificio más pequeño, de una sola planta, se dedica a jardín de infancia. Consta de: tres locales para reunión de grupos, sala de juegos, un despacho para la directora y una vivienda para la encargada de la guardería, además de los servicios de cocina y aseos correspondientes.
La otra edificación, desarrollada en dos alturas, se destina en su totalidad a la comunidad adulta. Se compone, en la planta baja de: capilla, club de ancianos, sala de reunión y otra de juegos, zona de administración y vivienda del pastor organizada en dúplex; y en el nivel superior se distribuyen: la biblioteca, sala de catequesis y enseñanza, despachos y dos viviendas —una para el sacristán y la otra para la día conisa—.
En la construcción se emplearon sistemas y materiales tradicionales, los cuales, siempre que fue posible, se dejaron vistos en su estado natural. De esta manera se ha conseguido un agradable contraste de texturas y colores, y una gran sencillez de líneas, armonizando perfectamente en el entorno de tipo rural

High failure rate of the interspinous distraction device (X-Stop) for the treatment of lumbar spinal stenosis caused by degenerative spondylolisthesis
The X-Stop interspinous distraction device has shown to be an attractive alternative to conventional surgical procedures in the treatment of symptomatic degenerative lumbar spinal stenosis. However, the effectiveness of the X-Stop in symptomatic degenerative lumbar spinal stenosis caused by degenerative spondylolisthesis is not known. A cohort of 12 consecutive patients with symptomatic lumbar spinal stenosis caused by degenerative spondylolisthesis were treated with the X-Stop interspinous distraction device. All patients had low back pain, neurogenic claudication and radiculopathy. Pre-operative radiographs revealed an average slip of 19.6%. MRI of the lumbosacral spine showed a severe stenosis. In ten patients, the X-Stop was placed at the L4–5 level, whereas two patients were treated at both, L3–4 and L4–5 level. The mean follow-up was 30.3 months. In eight patients a complete relief of symptoms was observed post-operatively, whereas the remaining 4 patients experienced no relief of symptoms. Recurrence of pain, neurogenic claudication, and worsening of neurological symptoms was observed in three patients within 24 months. Post-operative radiographs and MRI did not show any changes in the percentage of slip or spinal dimensions. Finally, secondary surgical treatment by decompression with posterolateral fusion was performed in seven patients (58%) within 24 months. In conclusion, the X-Stop interspinous distraction device showed an extremely high failure rate, defined as surgical re-intervention, after short term follow-up in patients with spinal stenosis caused by degenerative spondylolisthesis. We do not recommend the X-Stop for the treatment of spinal stenosis complicating degenerative spondylolisthesis
