We present a toy world model for interpreting textual descriptions of the movement record of a historical figure such as Genghis Khan or Napoleon. We cast the problem of document understanding as the task of finding episodes that do not violate the soft constraint conditions derived from the document. The model thus allows us to infer his or her locations by finding multiple solutions of an opt...

Background: Chemical exposure is a major health problem globally. Poison control centers (PCCs) play a leading role both in developed and developing countries in the prevention and control of poisonous chemical exposures. In this study, we aimed to assess the current state of PCCs in Pakistan and highlight capacity building needs in these centers. Methods: A cross-sectional survey of the two re...

This paper considers information bounds for semiparametric models with endogenous regressors, under different support conditions on the outcome variable as well as the endogenous regressor. Our base case is the model where both the outcome variable and the endogenous regressor are binary. Our first result is that under stated conditions, the information for the coefficient on the endogenous var...

Mongols had been a constant problem for the Sultans of Delhi. During Alauddin Khalji’s reign, there were in all six major invasions. The Sultan took strong action against them. His brae general, Zafar Khan, who become terror them gave resistance to While fighting with at Kili, Khan lost his life.

We examine a policy proposed by Stiglitz in the context of a multi-sector model proposed by Robinson, Solow, and Srinivasan (henceforth the RSS model) and recently reconsidered by Khan and Mitra. We characterize the policy by drawing on and extending dynamical systems theory in order to divide the parameter space into regions of a unique attracting cycle of each period and a region of no attrac...

In this paper, we use a one-step iteration scheme to approximate common fixed points of two quasi-asymptotically nonexpansive mappings. We prove weak and strong convergence theorems in a uniformly convex Banach space. Our results generalize the corresponding results of Yao and Chen [15] to a wider class of mappings while extend those of Khan, Abbas and Khan [4] to an improved one-step iteration...

The learning system provided by the municipalities is one of the most important motivating factors make citizens to participate in urban management plans such as source separation of wastes. In the past years, Tehran municipality has been focusing on providing different training in waste management and specifically source separation, which has not been able to attract public participation. The ...
