Understanding the complex brain computations leading to object recognition requires quantitatively characterizing the information represented in inferior temporal cortex (IT), the highest stage of the primate visual stream. A read-out technique based on a trainable classifier is used to characterize the neural coding of selectivity and invariance at the population level. The activity of very sm...

A series of glycan-coated quantum dots were prepared to probe the effect of glycan presentation in intracellular localization in HeLa and SV40 epithelial cells. We show that glycan density mostly impacts on cell toxicity, whereas glycan type affects the cell uptake and intracellular localization. Moreover, we show that lactose can act as a "Trojan horse" on bi-functionalized QDs to help intrace...

Education, Benefitting from Oil Revenues, and Sustainable Development A. Ansari, Ph.D. To assess the status of Iranian educational system within a special conceptual framework of economic development, a number of existing documents related to the expenditure of oil revenues on education were critically reviewed. The results show that within any economic framework in which sustainable deve...

With the invitation from the Fund Operator the participants received a Discussion Paper a short briefing paper providing a brief overview of the Active Citizens Fund and outlining the Fund Operator’s proposal regarding the main challenges to be addressed within the scope of the Active Citizens Fund. The Discussion Paper also invited the stakeholders to reflect on some open questions regarding i...

This paper presents an approach to model selection for regularized least-squares on reproducing kernel Hilbert spaces in the semi-supervised setting. The role of effective dimension was recently shown to be crucial in the definition of a rule for the choice of the regularization parameter, attaining asymptotic optimal performances in a minimax sense. The main goal of the present paper is showin...

We study properties of algorithms which minimize (or almost-minimize) empirical error over a Donsker class of functions. We show that the L2-diameter of the set of almost-minimizers is converging to zero in probability. Therefore, as the number of samples grows, it is becoming unlikely that adding a point (or a number of points) to the training set will result in a large jump (in L2 distance) t...

In this paper we focus on the problem of estimating a bounded density using a finite combination of densities from a given class. We consider the Maximum Likelihood Procedure (MLE) and the greedy procedure described by Li and Barron [6, 7]. Approximation and estimation bounds are given for the above methods. We extend and improve upon the estimation results of Li and Barron, and in particular p...

iqala (cancelling of the contract) is a legal act that is formed by sides' satisfactory contract and makes it breakup. imami, hanbali and shafei jurists revocate the iqala. hanafi jurists account iqala revocation into sides of contract, but a new transaction into outsiders. from the maleki jurists viewpoint, iqala is a new transaction, but civil code accounts the iqala tafasokh (breaking u...
