Uncovering Gatsby Curves

Pier-André Bouchard St-Amant, Jean-Denis Garon, Nicolas Marceau
2020 Social Science Research Network  
Empirical findings suggest a positive correlation between inequality and social immobility, a phenomenon coined the Gatsby curve. However, complete explanations of the phenomenon have not yet been proposed. This paper answers two questions: What are Gatsby curves? When do they exist? We build a theoretical environment in which parental investment and education improve the economic prospects of children. Gatsbian economies and Gatsby curves are formally defined, and we characterize the
more » ... under which they will arise. We show that an economy may go from being Gatsbian to non-Gatsbian. Finally, we show that the better network of relations of those with high-paying jobs may also generate a Gatsbian economy.

Theano: new features and speed improvements [article]

Frédéric Bastien, Pascal Lamblin, Razvan Pascanu, James Bergstra, Ian Goodfellow, Arnaud Bergeron, Nicolas Bouchard, David Warde-Farley, Yoshua Bengio
2012 arXiv   pre-print
Theano is a linear algebra compiler that optimizes a user's symbolically-specified mathematical computations to produce efficient low-level implementations. In this paper, we present new features and efficiency improvements to Theano, and benchmarks demonstrating Theano's performance relative to Torch7, a recently introduced machine learning library, and to RNNLM, a C++ library targeted at recurrent neural networks.

Optimal Control Under Uncertainty and Bayesian Parameters Adjustments

Nicolas Baradel, Bruno Bouchard, Ngoc Minh Dang
2018 SIAM Journal of Control and Optimization  
We propose a general framework for studying the optimal impulse control problem in the presence of uncertainty on the parameters. Given a prior on the distribution of the unknown parameters, we explain how it should evolve according to the classical Bayesian rule after each impulse. Taking these progressive prior-adjustments into account, we characterize the optimal policy through a quasi-variational parabolic equation, which can be solved numerically. The derivation of the dynamic programming

Oral Health and Blood Pressure: The IPC Cohort

Christelle Darnaud, Frédérique Thomas, Bruno Pannier, Nicolas Danchin, Philippe Bouchard
2015 American Journal of Hypertension  
The worldwide prevalence of hypertension is forecast to reach 29.2% by 2025. 1 Cardiovascular diseases (CVD), particularly ischemic heart disease and stroke, were among the leading causes of death worldwide between 2002 and 2012. 2 According to WHO projections for 2030, this trend will likely continue. 3 Several lines of evidence show that lowgrade inflammation plays a key role in increasing CVD, 4 and hypertension can be considered a state of systemic inflammation. However, it is difficult to
more » ... etermine whether the proinflammatory state associated with hypertension is a cause or a consequence of CVD. 5 Poor oral health has been associated with higher levels of low-grade inflammation and CVD risk. 6, 23, 24 The present observational study aimed to investigate if there is an association between oral status and the risk of hypertension in a large French subject cohort. METHODS Study population The population analysis comprised 102,330 participants (mean age 43.7 ± 12.7 years) who had undergone medical and dental examinations between January 2002 and December 2011, in Parisian medical centers subsidized by the French National Healthcare System (Centre d'Investigations Préventives et Cliniques: IPC). The sample was split according to age, one subset was <65 years (n = 96,435; male 63.3%), and the other was ≥65 (n = 5,895; male 53.9%). Clinical and biological investigations Each subject underwent biological and morphometric examination. The subjects were placed in the supine position. After 10 minutes of rest, blood pressure measurements were recorded by a trained nurse, three times consecutively with an electronic device (TM-2541 hemodynamometer A&D Company, Tokyo, Japan). The mean of the second and third measurements was used for analysis. Hypertension was defined as systolic blood pressure (SBP) higher than 140 mm Hg and/or diastolic blood pressure (DBP) higher than 90 mm Hg. Normal blood pressure was defined in three classes: SBP <120 mm Hg and DBP <80 mm Hg, SBP of 120-129 mm Hg and DBP of 80-84 mm Hg, SBP of 130-139 mm Hg and DBP of 85-89 mm Hg. 7 Body BaCkgrOunD Chronic periodontal diseases involve bacteria-induced inflammation of the tissues supporting the teeth. An inflammatory origin for hypertension has been proposed, and periodontal diseases are associated with an increased risk of vascular disease. The present study was performed to assess whether oral health conditions were associated with the risk of hypertension in adult population. METHODS The sample comprised 102,330 subjects, who underwent medical and oral examinations between 2002 and 2011. A full-mouth clinical examination was performed using simplified plaque index, calculus index, and simplified modified gingival index to assess dental plaque, dental calculus and gingival inflammation. The number of teeth was recorded. Biological parameters, including blood pressure were assessed. A subset analysis according to age (<65 or ≥65 years) was conducted. The association between blood pressure and oral conditions was explored using a logistic regression approach. rESulTS In the sample of subject ≥65 years, no significant association was found between oral variables and the risk of hypertension. In subset <65 years, oral variables and risk of hypertension were associated. Insufficient masticatory function and missing teeth (>10) showed odds ratio (OR) = 1.20 [95% CI = 1.08-1.32] and OR = 1.17 [95% CI = 1.04-1.31], respectively. Hypertension was also associated with high level of dental plaque [OR = 1.90, 95% CI = 1.55-2.33], dental calculus [OR = 1.18, 95% CI = 1.07-1.29] and gingival inflammation [OR = 1.56, 95% CI = 1.35-1.80] Moreover, in this subset <65 years, the risk of hypertension increases with the number of dental exposure. COnCluSiOnS The present study indicates that insufficient masticatory function, poor oral hygiene, and oral inflammation are associated with hypertension in subject <65.

Observation of quantum recoherence of photons by spatial propagation

Frédéric Bouchard, Jérémie Harris, Harjaspreet Mand, Nicolas Bent, Enrico Santamato, Robert W. Boyd, Ebrahim Karimi
2015 Scientific Reports  
Entanglement is at the heart of many unusual and counterintuitive features of quantum mechanics. Once two quantum subsystems have become entangled, it is no longer possible to ascribe an independent state to either; instead, the subsystems are completely described only as part of a greater, composite system. As a consequence of this, each entangled subsystem experiences a loss of coherence following entanglement. We refer to this decrease in coherence as decoherence. Decoherence leads
more » ... to the leaking of information from each subsystem to the composite entangled system. Here, we demonstrate a process of decoherence reversal, whereby we recover information lost from the entanglement of the optical orbital angular momentum and radial profile degrees of freedom possessed by a photon pair. These results carry great potential significance, since quantum memories and quantum communication schemes depend on an experimenter's ability to retain the coherent properties of a particular quantum system.

Cannabinoid Receptor CB2 Modulates Axon Guidance

Gabriel Duff, Anteneh Argaw, Bruno Cecyre, Hosni Cherif, Nicolas Tea, Nawal Zabouri, Christian Casanova, Maurice Ptito, Jean-François Bouchard, Alain Chédotal
2013 PLoS ONE  
Navigation of retinal projections towards their targets is regulated by guidance molecules and growth cone transduction mechanisms. Here, we present in vitro and in vivo evidences that the cannabinoid receptor 2 (CB 2 R) is expressed along the retino-thalamic pathway and exerts a modulatory action on axon guidance. These effects are specific to CB 2 R since no changes were observed in mice where the gene coding for this receptor was altered (cnr2 2/2 ). The CB 2 R induced morphological changes

Interfering with endogenous CB 2 R signalling using pharmacological agents increased retinal axon length and induced aberrant projections. Additionally, cnr2 2/2 mice showed abnormal eye-specific segregation of retinal projections in the dorsal lateral geniculate nucleus (dLGN) indicating CB 2 R's implication in retinothalamic development. Overall, this study demonstrates that the contribution of endocannabinoids to brain development is not solely mediated by CB 1 R, but also involves CB 2 R.
