W. Alan C. Mutch,Randall R. Fransoo,Barry I. Campbell,Dan G. Chateau,Monica Sirski,R. Keith Warrian
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0017457
Abstract: We compared the proportion of ischemic heart disease (IHD) patients newly diagnosed with dementia and depression across three treatment groups: percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and medical management alone (IHD-medical).
Arde París? Percepciones e imaginarios de la prensa chilena y argentina en torno a los disturbios del oto o 2005
Manuel Gárate Chateau
Polis : Revista de la Universidad Bolivariana , 2006,
Abstract: La imaginación constituye uno de los elementos menos estudiados de la política y de la historia política. Sin embargo, ella es capaz de alimentar visiones e incluso realidades mucho allá de lo que se supone. Incluso en un mundo interconectado donde las informaciones circulan casi instantáneamente, los imaginarios sobre sucesos ocurridos al otro lado del planeta aún generan efectos e interpretaciones con características eminentemente locales. Los recientes disturbios urbanos del oto o francés 2005 no han sido la excepción, y han dado pie a una profusión de artículos y editoriales que especulan sobre una posible nueva revolución y los efectos que ésta pudiese tener sobre Europa y el resto del mundo. En este artículo intentamos descifrar algunas de esas representaciones al comparar la prensa chilena y argentina y contrastarlas con lel debate producido en Francia.
Valuing European Put Options under Skewness and Increasing [Excess] Kurtosis  [PDF]
John-Peter D. Chateau
Journal of Mathematical Finance (JMF) , 2014, DOI: 10.4236/jmf.2014.43015
Abstract:

To capture the impact of skewness and increase kurtosis on Black’s [1] European put values, we first substitute a Gram-Charlier (GC) distribution and next a Johnson distribution for Black’s Gaussian one. We introduce next each distribution in the option payoff and develop until the closedform expression of each put is arrived at. Finally, we estimate by simulations GC, Johnson and Black put options, choosing the latter one as benchmark. Simulation estimates encompassing both skewness and kurtosis show that, for at-the-money (ATM) or slightly in-the-money put values, 1) Black’s overvaluation with respect to Johnson puts is very significant and 2) its undervaluation with respect to GC ones remains moderate. Yet, by using the same skewness values for both GC and Johnson puts, we highlight the differences induced by increasing kurtosis between the two models. In this case, the GC overvaluation for ATM values is explained by value differences in the put time component. Yet, while both Black and GC values exhibit significant time decay close to expiry, Johnson’s ones remain stable up to maturity.

Pricing the Credit-Risk Put Embedded in Borrowers’ Extendible Credit Commitments, with Its Application to Basel-3 Micro-Prudential Regulation  [PDF]
John-Peter D. Chateau
Journal of Mathematical Finance (JMF) , 2016, DOI: 10.4236/jmf.2016.65052
Abstract: This research makes two contributions: 1) use a term structure framework to price analytically the put option implicit in borrowers’ extendible credit commitments and 2) use the latter to compute in a ratings-based model the capital charge corresponding to the credit-risk exposure of such commitments. Since the term structure of interest rates is stochastic, the zero-coupon bonds in the put closed-form solution delink discounting factor from the credit and funding rates that define the credit spread appearing in the put payoff. By essence, extendible commitments straddle the term-based commitment classification of Basel-3 simplified approach. To improve this, we formulate a ratings-based model that combines extendible put values with new coefficients (forward funding proportion and exposure at funding) as well as a matrix that captures credit-ratings migration over time. Moreover, the combination is versatile enough to deal with a borrower’s credit downgrade and its attendant incremental Basel-3 capital charge.
La Dive bouteille en France : une analyse sémiologique et linguistique de son discours et de ses images

COnTEXTES : Revue de Sociologie de la Littérature , 2009, DOI: 10.4000/contextes.4485
Abstract: Tout dégustateur le sait : la dégustation du vin, c’est en même temps celle des mots. Ils en disent long sur le vin, mais aussi sur celui qui en parle et sur le monde qui nous entoure. En 1957, R. Barthes remarquait dans Mythologies, dans l’article intitulé Le vin et le lait , que le vin est senti par la nation fran aise comme un bien qui lui est propre, au même titre que ses trois cent soixante espèces de fromages et sa culture. Qu’en est-il en France, à l’heure actuelle, de cette...

Long-term martial arts practice has been proposed as an avenue to counter these deleterious effects. The general purpose of this pilot study was to identify the effects of an adapted karate training program on QOL, depression, and motor skills in 50-year-old men. Methods and design: Fifteen 50-year-old men were enrolled in a one-year prospective experiment. Participants practiced adapted karate training for 90 minutes three times a week. Testing sessions, involving completion of the MOS 36-item Short Form Health Survey (SF36) and Beck Depression Inventory, as well as motor and effort evaluation, were done at baseline, and six and 12 months. Results: Compared with baseline, participants had better Beck Depression Inventory scores after one year of karate training (P < 0.01) and better perception of their physical health (P < 0.01), but not on the mental dimension (P < 0.49). They also improved their reaction time scores for the nondominant hand and sway parameters in the eyes-closed position (P < 0.01). Conclusion: Regular long-term karate practice had favorable effects on mood, perception of physical health confirmed by better postural control, and improved performance on objective physical testing. Adapted karate training would be an interesting option for maintaining physical activity in aging.
The LOFT Burst Alert System and its Burst On-board Trigger

Physics , 2014, DOI: 10.1117/12.2055078
Abstract: The ESA M3 candidate mission LOFT (Large Observatory For x-ray Timing) has been designed to study strong gravitational fields by observing compact objects, such as black-hole binaries or neutron-star systems and supermassive black-holes, based on the temporal analysis of photons collected by the primary instrument LAD (Large Area Detector), sensitive to X-rays from 2 to 50 keV, offering a very large effective area (>10 m 2 ), but a small field of view ({\o}<1{\deg}). Simultaneously the second instrument WFM (Wide Field Monitor), composed of 5 coded-mask camera pairs (2-50 keV), monitors a large part of the sky, in order to detect and localize eruptive sources, to be observed with the LAD after ground-commanded satellite repointing. With its large field of view (>{\pi} sr), the WFM actually detects all types of transient sources, including Gamma-Ray Bursts (GRBs), which are of primary interest for a world-wide observers community. However, observing the quickly decaying GRB afterglows with ground-based telescopes needs the rapid knowledge of their precise localization. The task of the Loft Burst Alert System (LBAS) is therefore to detect in near- real-time GRBs (about 120 detections expected per year) and other transient sources, and to deliver their localization in less than 30 seconds to the observers, via a VHF antenna network. Real-time full resolution data download to ground being impossible, the real-time data processing is performed onboard by the LBOT (LOFT Burst On-board Trigger system). In this article we present the LBAS and its components, the LBOT and the associated ground-segment.
Influence of shear stress applied during flow stoppage and rest period on the mechanical properties of thixotropic suspensions
Guillaume Ovarlez,Xavier Chateau
Physics , 2008, DOI: 10.1103/PhysRevE.77.061403
Abstract: We study the solid mechanical properties of several thixotropic suspensions as a function of the shear stress history applied during their flow stoppage and their aging in their solid state. We show that their elastic modulus and yield stress depend strongly on the shear stress applied during their solid-liquid transition (i.e., during flow stoppage) while applying the same stress only before or only after this transition may induce only second-order effects: there is negligible dependence of the mechanical properties on the preshear history and on the shear stress applied at rest. We also found that the suspensions age with a structuration rate that hardly depends on the stress history. We propose a physical sketch based on the freezing of a microstructure whose anisotropy depends on the stress applied during the liquid-solid transition to explain why the mechanical properties depend strongly on this stress. This sketch points out the role of the internal forces in the colloidal suspensions' behavior. We finally discuss briefly the macroscopic consequences of this phenomenon and show the importance of using a controlled-stress rheometer.
Elastic modulus of a colloidal suspension of rigid spheres at rest
Laurentiu Pasol,Xavier Chateau
Physics , 2009, DOI: 10.1016/j.crme.2008.03.001
Abstract: By modeling a colloidal suspension at rest as a solid, a new expression for the linear elastic modulus is obtained. This estimate is valid for a yield stress colloidal suspension submitted to a small strain. Interestingly, it is also possible to construct an hypothesis allowing one to recover the high-frequency modulus classically found by means of a classical ?fluid approach'. However, in most of the situations, the moduli obtained by the two approaches are different.
