Diffusion MRI is based on the measurement of Brownian motion of water molecules. It is possible to use this diffusion property as a probe to study the structure of spatial order in living brain tissues noninvasively. This paper put forward with a unified tracking algorithm based on diffusion tensor imaging, diffusion spectrum imaging and Q-Ball imaging. By applying the three methods to the same...

The Differentiation of Self Inventory—Revised (DSI-R; Skowron & Schmitt, 2003, “Assessing interpersonal fusion: Reliability and validity of a new DSI fusion with others subscale,” Journal of Marital and Family Therapy, 29, 209–222) assesses a central construct of Murray Bowen’s Family Systems Theory. Differentiation of self (DoS) consists of both intraand interpersonal dimensions, or the capaci...

Diffusion spectrum imaging (DSI) has been demonstrated to resolve crossing axonal fibers by mapping the probability density function of water molecules diffusion at each voxel. However, the accuracy of DSI in defining individual fiber orientation and the validity of Fourier relation under finite gradient pulse widths are not assessed yet. We developed an ex vivo and an in vivo model to evaluate...

Photonic bandgap (PBG) regions have been calculated for periodically grooved Si structures, acting as a one-dimensional photonic crystal. The wavelength range of the PBG as a function of the ratio (DSi/A) is presented, where DSi is the width of the Si walls and A is the grooved silicon lattice constant. The influence of the parameter DSi, the refractive index of the space between the Si walls a...

Professors Bloch, Lubbers, and Verkuil have performed a yeomen’s service in advising the Commissioner of the Social Security Administration (SSA) on reforming the process for administrative decision making and appeals.1 In a well-balanced article for this Symposium, the professors generally praise the Commissioner’s new Disability Service Improvement (DSI) process, which SSA will phase in start...

INTRODUCTION The diffusion spectrum imaging (DSI) technique [1] can map the probability density of the average relative spin displacement in a voxel, and has a unique capability to resolve complex intravoxel diffusion heterogeneity. This capacity is important because the voxel sizes in typical MRI experiments are large with respect to the diffusion scale, and the signal within each voxel can re...

Purpose: To compare the performance of the Dichotic Sentence Identification (DSI) test in the Brazilian Portuguese version, considering: the right and left ears and the educational status in normal-hearing individuals. Methods: This investigation assessed 200 individuals who are normal listeners and right-handed and were divided into seven groups according to the years of schooling. All the par...

In this paper, we propose a divisibility management framework for e-cash algorithms. The proposed framework is based on the dependency graph of a hypercube, which is constructed from all subcubes of a hypercube, to keep track of partitioned spending of the resource pool represented by the hypercube. On the basis of Eng and Okamoto's recursive key generation equation, we develop an analysis fram...
