Il est un temps de mourir et un temps de ne pas mourir de révolte perpétuelle. Benjamin Fondane, Titanic , 1937 Rien de plus dangereux que l’hommage ; rien de plus gla ant que la mémoire autorisée, assagissant le réel, rendant inoffensifs les assauts les plus rudes, désamor ant les subversions les plus puissantes pour en faire des objets saints 1 . On conna t l’obstacle. La biographie comme une immense chausse-trappe pour l’ uvre. La mise en scène comme une obsession du ...

Abstract:
Qu’est-ce qui aurait bien pu m’attirer dans ce pays déshérité, sinon le désir d’y rester 1 ? Telle serait l’antienne incompréhensible du converti au juda sme, son credo insolite. La formule de Kafka, reprise par Sébastien Tank, et qui résonne comme le pendant imprévu du ticket d’entrée de Heine dans le monde des nations , comme son inversion surprenante au siècle des tragédies, donne bien la mesure des mystères et des ambivalences propres au ...

Abstract:
A new model for biological growth is introduced that couples the geometry of an organism (or part of the organism) to the flow and deposition of material. The model has three dynamical variables (a) a Riemann metric tensor for the geometry, (b) a transport velocity of the material and (c) a material density. While the model was developed primarily to determine the effects of geometry (i.e. curvature and scale changes) in two-dimensional systems such as leaves and petals, it can be applied to any dimension. Results for one dimensional systems are presented and compared to measurements of growth made on blades of grass and corn roots. It is found that the model is able to reproduce many features associated with botanical growth.

Abstract:
We develop a new form of patching that is both far-reaching and more elementary than the previous versions that have been used in inverse Galois theory for function fields of curves. A key point of our approach is to work with fields and vector spaces, rather than rings and modules. After presenting a self-contained development of this form of patching, we obtain applications to other structures such as Brauer groups and differential modules.

Abstract:
Let $G$ be a connected reductive group over a non-Archimedean local field. We prove that its parahoric subgroups are definable in the Denef-Pas language, which is a first-order language of logic used in the theory of motivic integration developed by Cluckers and Loeser. The main technical result is the definability of the connected component of the N\'eron model of a tamely ramified algebraic torus. As a corollary, we prove that the canonical Haar measure on $G$, which assigns volume $1$ to the particular \emph{canonical} maximal parahoric defined by Gross, is motivic. This result resolves a technical difficulty that arose in Cluckers-Gordon-Halupczok and Shin-Templier and permits a simplification of some of the proofs in those articles. It also allows us to show that formal degree of a compactly induced representation is a motivic function of the parameters defining the representation.

Abstract:
Let E be an elementary abelian p-group of rank r and let k be a field of characteristic p. We introduce functors F_i from finitely generated kE-modules of constant Jordan type to vector bundles over projective space of dimension r-1. The fibers of these functors encode complete information about the Jordan type of the module. We prove that given any vector bundle of rank s on P^{r-1}, there is a kE-module M of stable constant Jordan type [1]^s such that the functor F_1 applied to M yields the original vector bundle for p=2 and the Frobenius twist of the original vector bundle for p>2. We also prove that the theorem cannot be improved if p is odd, because if M is any module of stable constant Jordan type [1]^s then the Chern numbers c_1, ... ,c_{p-2} of F_1(M) are divisible by p.

Abstract:
We followed-up 6,095 men and women aged >=16 years who participated 1977--79 in a community based health study and were anonymously linked with the Swiss National Cohort until the end of 2008. During follow-up, 727 participants died of CVD. Based on the ESC SCORE methodology (Weibull regression), we used age, sex, blood pressure, smoking, and fasting glucose or total cholesterol. The mean Brier score (BS), area under the receiver-operating characteristic curve (AUC) and integrated discrimination improvement (IDI) were used for model comparison. We validated our models internally using cross-validation and externally using another data set.In our models, the p-value of total cholesterol was 0.046, that of glucose was p < 0.001. The model with glucose had a slightly better predictive capacity (BS: 2216x10-5 vs. 2232x10-5; AUC: 0.9181 vs. 0.9169, IDI: 0.009 with p-value 0.026) and could well discriminate the overall risk of persons with high and low concentrations. The external validation confirmed these findings.Our study suggests that instead of total cholesterol glucose can be used in models predicting overall CVD mortality risk.

Abstract:
Mechanically induced adaptation of bone is required to maintain a healthy skeleton and defects in this process can lead to dramatic changes in bone mass, resulting in bone diseases such as osteoporosis. Therefore, understanding how this process occurs could yield novel therapeutics to treat diseases of excessive bone loss or formation. Over the past decade the primary cilium has emerged as a novel extracellular sensor in bone, being required to transduce changes in the extracellular mechanical environment into biochemical responses regulating bone adaptation. In this review, we introduce the primary cilium as a novel extracellular sensor in bone; discuss the in vitro and in vivo findings of primary cilia based sensing in bone; explore the role of the primary cilium in regulating stem cell osteogenic fate commitment and finish with future directions of research and possible development of cilia targeting therapeutics to treat bone diseases.

Abstract:
Introduction: The EasyTube is a disposable, polyvinyl-chloride, double-lumen, supraglottic airway device, which allows ventilation in either esophageal or tracheal position. The EasyTube may be positioned into the esophagus blindly or using a laryngoscope. Methods: Our study compared blind versus laryngoscopic-guided esophageal EasyTube insertion. Thirty two anesthesiologists inserted an EasyTube, size 41 Fr, into a mannequin, by using a blind and a laryngoscopic technique in a 2 × 2 crossover design. Results: No statistically significant difference in the time to achieve an effective airway was found: 23.9 ± 6 seconds for the blind and 29.5 ± 7.6 seconds for the laryngoscopic-guided technique. Conclusion: EasyTube insertion was equally successful with or without a laryn-goscope in a mannequin when used by anesthesia providers.

Abstract:
We realize a continuous guided beam of cold deuterated ammonia with a flux of 3e11 ND3 molecules/s and a continuous free-space beam of cold potassium with a flux of 1e16 K atoms/s. A novel feature of the buffer gas source used to produce these beams is cold neon, which, due to intermediate Knudsen number beam dynamics, produces a forward velocity and low-energy tail that is comparable to much colder helium-based sources. We expect this source to be trivially generalizable to a very wide range of atomic and molecular species with significant vapor pressure below 1000 K. This source has properties that make it a good starting point for laser cooling of molecules or atoms, cold collision studies, trapping, or nonlinear optics in buffer-gas-cooled atomic or molecular gases.
