Nondeclarative memory and novelty processing in the brain is an actively studied field of neuroscience, and reducing neural activity with repetition of a stimulus (repetition suppression) is a commonly observed phenomenon. Recent findings of an opposite trend-specifically, rising activity for unfamiliar stimuli-question the generality of repetition suppression and stir debate over the underlyin...

This study examines dynamic interrelationships and causality relationships among CO2 emissions, economic, political and financial variables over the period of 1971-2011 for the case of Iran as one of the top CO2 emitting countries in the world. The results of ARDL and Johansen cointegration approaches confirm the existence of long run relationship among CO2 emissions, energy consumption, GDP, f...

Using detailed stockholding for a comprehensive sample of Chinese mutual funds from 2004 to 2009, we investigate the economy of scale and liquidity on the relation between fund size and performance. We find that there exists an inverted U-shape relation between fund size and performance accounting for various performance benchmarks. Both economy of scale and liquidity exist and play an importan...

Assume individuals are treated if a latent variable, containing a continuous instrument, lies between two thresholds. We place no functional form restrictions on the latent errors. Here unconfoundedness does not hold and identification at infinity is not possible. Yet we still show nonparametric point identification of the average treatment effect. We provide an associated root-n consistent est...

Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...

Inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. In the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. This article presents the results of a prospective study of24 patients with inverted papilloma resected by...

Many psychological and physiological studies with simple stimuli have suggested that perceptual learning specifically enhances the response of primary sensory cortex to task-relevant stimuli. The aim of this study was to determine whether auditory discrimination training on complex tasks enhances primary auditory cortex responses to a target sequence relative to non-target and novel sequences. ...
