The features of bad flow unit continuity and multiple layers emphesize the importance of a well pattern design for the development of a fluvial-delta reservoir. It is proposed a method to predict well pattern connectivity (WPC) based on the exploration and evaluation of wells. Moreover, the method helps evaluate the risk of well placement. This study initially establishes the parameters for cha...

The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...

Whenever we engage in a cognitive task, multiple brain regions are engaged. Understanding how these regions interact is a fundamental step to uncover the neural mechanisms that make behavior possible. The majority of the investigations of interactions between brain regions have focused on the overall univariate responses in the regions. However, in the context of ‘static’ analyses, drastic adva...

Nowadays, numerical modelings play a key role in analyzing hydraulic problems in fractured rock media. The discrete fracture network model is one of the most used numerical models to simulate the geometrical structure of a rock-mass. In such media, discontinuities are considered as discrete paths for fluid flow through the rock-mass while its matrix is assumed impermeable. There are two main pa...

In [3], [4], [5] Sellers developes a dynamic programming pattern matching algorithm that generates forward, reverse, and transverse path graphs that determine the best resemblance (lowest cost) of a smaller string pattern inside a larger. In this paper we study the properties and structure of these graphs. We show that these path graphs can be decomposed into a small number of distinct block ty...

The aim of this work is to characterize quantitatively the performance of a body of techniques in the frequency domain for the estimation of cortical connectivity from high-resolution EEG recordings in different operative conditions commonly encountered in practice. Connectivity pattern estimators investigated are the Directed Transfer Function (DTF), its modification known as direct DTF (dDTF)...

INTRODUCTION Low-frequency (<0.1Hz) spontaneous fluctuations in resting-state fMRI have been used to study functional connectivity in brain networks (1, 2). However, the underlying mechanism and contrast-to-noise ratio (CNR) of the connectivity remain inconclusive (3). While the CNR of stimulation-induced brain activation has been well studied, much less is known about the optimization of funct...

Introduction: Long-term stressful situations can drastically influence one&rsquo;s mental life. However, the effect of mental stress on recognition of emotional stimuli needs to be explored. In this study, recognition of emotional stimuli in a stressful situation was investigated. Four emotional conditions, including positive and negative states in both low and high levels of arousal were analy...
