In this paper we study estimation of DSGE models. More specifically, in the indirect inference framework, we analyze how critical is the choice of the reduced form model for estimation purposes. As it turns out, simple VAR parameters performs better than commonly used impulse response functions. This can be attributed to the fact that IRF worsen identifica- tion issues for models that are already plagued by that phenomenon. [less ▲]

Hydrogen line profiles measured from space-borne or ground-based instruments provide useful information to study the physical processes occurring in the proton aurora and to estimate the proton flux characteristics. The line shape of the hydrogen lines is determined by the velocity distribution of H atoms along the line-of-sight of the instrument. Calculations of line profiles of auroral hydrogen emissions were obtained using a Monte Carlo kinetic model of proton precipitation into the auroral atmosphere. In this model both processes of energy degradation and scattering angle redistribution in momentum and charge transfer collisions of the high-energy proton/hydrogen flux with the ambient atmospheric gas are considered at the microphysical level. The model is based on measured cross sections and scattering angle distributions and on a stochastic interpretation of such collisions. Calculations show that collisional angular redistribution of the precipitating proton/hydrogen beam is the dominant process leading to the formation of extended wings and peak shifts in the hydrogen line profiles. All simulations produce a peak shift from the rest line wavelength decreasing with increasing proton energy. These model predictions are confirmed by analysis of ground-based H-beta line observations from Poker Flat, showing an anti-correlation between the magnitude of the peak shift and the extent of the blue wing of the line. Our results also strongly suggest that the relative extension of the blue and red wings provides a much better indicator of the auroral proton characteristic energy than the position of the peak wavelength.

A model of the photoelectron collision-induced component of the Mars dayglow using recent cross sections and solar flux is described. The calculation of the photoelectron source of excitation is based on a stochastic solution of the Boltzmann equation using the direct simulation Monte Carlo method. The neutral atmosphere is taken from outputs of a global circulation model, and recent inelastic collision cross sections are adopted. The calculated vertical profiles of the CO Cameron bands and CO[SUB]2[/SUB] [SUP]+[/SUP] doublet emissions integrated along the line of sight compare well with the Spectroscopy for the Investigation of the Characteristics of the Atmosphere of Mars (SPICAM) limb profiles observed with the SPICAM spectrograph on board Mars Express made at Ls = 166° during the summer season at northern midlatitudes. The comparison shows agreement to within the uncertainties of the excitation cross sections. Seasonal changes in the brightness and the altitude of the emission peaks are predicted with intensity variations in the range 15-20%. [less ▲]

Gate (Geant4 Application for Tomographic Emission), based on Monte Carlo methods allows simulation of full PET-acquisition processes. Gate results for one of CRC’s tomographs, the HR+, are in good agreement with real data, with a maximum mean difference of 6%. Monte Carlo simulations are highly CPU-consuming, so we had to parallelize simulations on the recently setup cluster. In order to use Gate properly on the cluster, the optimal number of CPU was determined. We studied the performances of the small animal microPET FOCUS 120 in terms of counting rate capability (NECR index) for comparison with future simulated results. [less ▲]

Much current research in AI and games is being devoted to Monte Carlo search (MCS) algorithms. While the quest for a single unified MCS algorithm that would perform well on all problems is of major interest for AI, practitioners often know in advance the problem they want to solve, and spend plenty of time exploiting this knowledge to customize their MCS algorithm in a problem-driven way. We propose an MCS algorithm discovery scheme to perform this in an automatic and reproducible way. We first introduce a grammar over MCS algorithms that enables inducing a rich space of candidate algorithms. Afterwards, we search in this space for the algorithm that performs best on average for a given distribution of training problems. We rely on multi-armed bandits to approximately solve this optimization problem. The experiments, generated on three different domains, show that our approach enables discovering algorithms that outperform several well-known MCS algorithms such as Upper Confidence bounds applied to Trees and Nested Monte Carlo search. We also show that the discovered algorithms are generally quite robust with respect to changes in the distribution over the training problems. [less ▲]

Monte-Carlo Tree Search is a new method which has been applied successfully to many games. However, it has never been tested on two-player perfect-information games with a chance factor. Backgam- mon is the reference game of this category. Today’s best Backgammon programs are based on reinforcement learning and are stronger than the best human players. These programs have played millions of offline games to learn to evaluate a position. Our approach consists rather in playing online simulated games to learn how to play correctly in the current position. [less ▲]

La scène du télégraphe optique, dans Le Comte de Monte-Cristo, aide à mettre en lumière la modernité du roman. Cette modernité tient pour une part à une ligne de continuité établie entre chronique judiciaire et fable romanesque, sur fond de réseau télégraphique. Elle tient plus encore au fait que cet épisode du télégraphe rend singulièrement visible l’allégorie de la communication que le roman développe à différents niveaux de sa construction narrative, allant de son incipit très sémiologique à la « voile blanche » qui signalera sur fond d’azur méditerranéen, quatorze cents pages plus loin, le départ d’un Monte-Cristo ayant recouvré son identité perdue, en passant par les deux figures successivement incarnées par son héros, dépeint en victime sacrificielle puis en expert d’une communication dont il saura jouer de tous les ressorts — rapidité de déplacement, contrôle de l’information, maîtrise des formes spéculatives et fiduciaires de l’économie, dévoiement des formes anthropologiques de l’échange social, etc. — pour l’emporter finalement sur les trois pouvoirs coalisés de la Politique (Morcerf), de la Justice (Villefort) et de la Banque (Danglars) ; tout cela orchestré par une triple métaphore du sang, de l’argent et de l’information, dont la signification réversible ne peut être séparée d’une doctrine saint-simonienne que Dumas à la fois relaie et révoque. De même que le couloir de communication établi au château d’If entre la cellule de Dantès et celle de Faria, la scène du télégraphe fait ainsi office de point de cristallisation d’une symbolique diffuse. Cette scène si cardinale, il s'agit ici de montrer qu’elle est non seulement grosse encore de tout un savoir à dimension technique autant qu’anthropologique, mais également porteuse, vers d’autres zones du roman, d’une assez étonnante préfiguration du télégraphe électrique, en cheville avec une modernité technique dont Dumas faufile les signes de façon plus ou moins cryptée dans la trame de son roman.

Oral ibandronate is the first bisphosphonate licensed for once-monthly treatment of postmenopausal osteoporosis. The 2-year Monthly Oral iBandronate In LadiEs (MOBILE) registration study assessed bone mineral density (BMD) and markers of bone turnover and showed that monthly oral ibandronate was at least as effective and well tolerated as a 2.5-mg daily oral regimen. In this study, we report the first year of a long-term extension study to MOBILE and a post hoc analysis of patients receiving 3 years of continuous treatment with monthly ibandronate. Patients who completed MOBILE were eligible for the partially randomized, double-blind extension study and received 100 mg (n = 359) or 150 mg (n = 360) monthly oral ibandronate. A post hoc analysis included patients who received either 100 mg (n = 173) or 150 mg (n = 169) monthly ibandronate continuously throughout the original 2-year MOBILE study and during the first year of the extension study. After one additional year of treatment (total of 3 years), mean lumbar spine BMD increased a further 1.5 and 1.1% in the 150 and 100 mg arms, respectively, compared with 2-year data (original MOBILE study). Total hip BMD changed by 0.3 and -0.08%, respectively. In the post hoc analysis, 3-year increases in lumbar spine BMD were significant in patients receiving ibandronate 150 mg monthly (7.6%; p < 0.0001 vs. baseline) and 100 mg monthly (6.4%; p < 0.0001 vs. baseline). Both groups achieved significant increases in total hip BMD after 3 years compared with baseline (3.4%, 100 mg; 4.1%, 150 mg; p < 0.0001). Serum C-telopeptide of the alpha chain of type I collagen decreased significantly over 3 years' treatment (p < 0.001; all comparisons vs. baseline), remaining within the premenopausal range. Once-monthly oral ibandronate was well tolerated with a low incidence of clinical osteoporotic fractures and upper gastrointestinal events. In conclusion, 150-mg monthly oral ibandronate is an effective and well-tolerated long-term treatment for postmenopausal osteoporosis, with consistent improvement in BMD and bone turnover during 3 years' continuous treatment.

Context: Ibandronate, a potent, nitrogen-containing bisphosphonate developed for intermittent administration in postmenopausal osteoporosis, aims to overcome current adherence issues with daily and weekly oral bisphosphonates through once-monthly oral dosing. Objective: The purpose of this study was to investigate the safety, pharmacodynamics, and pharmacokinetics of once-monthly oral ibandronate. Design: A randomized, 3-month, double-blind, placebo-controlled, phase I study (Monthly Oral Pilot Study) was conducted. Setting: The study was conducted at five clinical trial centers in the United Kingdom and Belgium. Patients or Other Participants: Subjects were postmenopausal women (age, 55 - 80 yr; >= 3 yr post menopause; n = 144). Intervention(s): Once-monthly oral ibandronate 50, 100, or 150 mg or placebo was used. After the first cycle, the 50-mg arm was split, with participants continuing on either 50 or 100 mg. Main Outcome Measure(s): Primary outcome measures were safety, serum and urinary C-telopeptide (CTX), and serum ibandronate AUC(0-infinity). Results: Once- monthly oral ibandronate was well tolerated, with a similar overall and upper gastrointestinal safety profile to placebo. Once- monthly ibandronate was also highly effective in decreasing bone turnover; substantial reductions from baseline in serum CTX (-56.7% and -40.7% in the 150- and 100- mg arms, respectively; P < 0.001 vs. placebo) and urinary CTX (-54.1% and -34.6%, respectively; P < 0.001 vs. placebo) were observed at d 91 (30 d after the final dose). Analysis of the area under the effect curve (d1 - 91) for change from baseline (percent x days) in serum CTX and urinary CTX indicated a dose- response relationship. The AUC(0-infinity) for ibandronate increased with dose but not in a dose- proportional manner. Conclusions: These findings indicate a potential role for once-monthly oral ibandronate in the treatment of postmenopausal osteoporosis. [less ▲]

Introduction: Suboptimal adherence to daily and weekly oral bisphosphonates can potentially compromise therapeutic outcomes in postmenopausal osteoporosis. Although yet to be prospectively shown in osteoporosis, evidence from randomized clinical trials in several other chronic conditions shows that reducing dosing frequency enhances therapeutic adherence. Ibandronate is a new and potent bisphosphonate with antifracture efficacy proven for daily administration and also intermittent administration with a dose-free interval of > 2 months. This report presents comparative data on the efficacy and safety of monthly and daily oral ibandronate regimens. Materials and Methods: MOBILE is a 2-year, randomized, double-blind, phase III, noninferiority trial. A total of 1609 women with postmenopausal osteoporosis were assigned to one of four oral ibandronate regimens: 2.5 mg daily, 50 mg/50 mg monthly (single doses, consecutive days), 100 mg monthly, or 150 mg monthly. Results: After 1 year, lumbar spine BMD increased by 3.9%, 4.3%, 4.1%, and 4.9% in the 2.5, 50/50, 100, and 150 mg arms, respectively. All monthly regimens were proven noninferior, and the 150 mg regimen superior, to the daily regimen. All monthly regimens produced similar hip BMD gains, which were larger than those with the daily regimen. All regimens similarly decreased serum levels of C-telopeptide, a biochemical marker of bone resorption. Compared with the daily regimen, a significantly larger proportion of women receiving the 100 and 150 mg monthly regimens achieved predefined threshold levels for percent change from baseline in lumbar spine (6%) or total hip BMD (3%). All regimens were similarly well tolerated. Conclusions: Monthly ibandronate is at least as effective and well tolerated as the currently approved daily ibandronate regimen in postmenopausal osteoporosis. [less ▲]

Cette étude examine un groupe de vases particuliers, qui amènent une série de questions intéressantes sur le statut de l’image divine et sur les modes de représentation du divin en Grèce ancienne. Il s’agit de documents attiques et italiotes sur lesquels une divinité est représentée à côté de sa propre statue. La question qui se pose d’emblée est celle du sens de ce type de figuration, qui « redouble » en quelque sorte la divinité. On tente de montrer ici que le « redoublement » n’est pas une simple redondance, car ces images mettent en scènes deux modes de présence différents. [less ▲]
