and the Séminaire de Développement in Paris, for helpful comments. Remaining errors are mine. I am grateful to the Ministry of Planning, Rwanda, which has provided me with the data, and in which I worked from 1984 to 1988 as a technical adviser for the French Cooperation and Development Ministry. I acknowledge funding from the World Bank for starting my(More)

The hippocampus is involved in spatial memory processes, as established in a variety of species such as birds and mammals including humans. In humans, some hippocampal-dependent memory functions may be lateralized, the right hippocampus being predominantly involved in spatial navigation. In rodents, the question of possible lateralization remains open.(More)

In the context of multivariate linear regression (MLR) models, it is well known that commonly employed asymptotic test criteria are seriously biased towards overrejection. In this paper, we propose a general method for constructing exact tests of possibly nonlinear hypotheses on the coefficients of MLR systems. For the case of uniform linear hypotheses, we(More)
According to systems consolidation, as hippocampal-dependent memories mature over time, they become additionally (or exclusively) dependent on extra-hippocampal structures. We assessed the recruitment of hippocampal and cortical structures on remote memory retrieval in a performance-degradation resistant (PDR; no performance degradation with time) versus(More)
—Emerging non-volatile memories (NVM) based on re-sistive switching mechanism (RS) such as STT-MRAM, OxRRAM and CBRAM etc., are under intense R&D investigation by both academics and industries. They provide high write/read speed, low power and good endurance (e.g.,) beyond mainstream NVMs, which allow them to be embedded directly with logic units for(More)
The estimation of accuracy and applicability of QSAR and QSPR models for biological and physicochemical properties represents a critical problem. The developed parameter of "distance to model" (DM) is defined as a metric of similarity between the training and test set compounds that have been subjected to QSAR/QSPR modeling. In our previous work, we(More)

To date the literature on quantile regression and least absolute deviation regression has assumed either explicitly or implicitly that the conditional quantile regression model is correctly specified. When the model is misspecified, confidence intervals and hypothesis tests based on the conventional covariance matrix are invalid. Although misspecification(More)
