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...

Zorro-LNA (Zorro) is a newly developed, oligonucleotide (ON)-based, Z-shaped construct with the potential of specific binding to each strand of duplex DNA. The first-generation Zorros are formed by two hybridized LNA/DNA mixmers (2-ON Zorros) and was hypothesized to strand invade. We have now established a method, which conclusively demonstrates that an LNA ON can strand invade into duplex DNA....

Heterosynaptic enhancement of transmitter release is potentially very important for neuronal computation, yet, to our knowledge, no prior study has shown that stimulation of one neuron directly enhances release from an interneuron. Here, we demonstrate that in the marine mollusk Tritonia diomedea, the serotonergic dorsal swim interneurons (DSIs) heterosynaptically increase the amount of transmi...

BACKGROUND Disease State Index (DSI) and its visualization, Disease State Fingerprint (DSF), form a computer-assisted clinical decision making tool that combines patient data and compares them with cases with known outcomes. AIMS To investigate the ability of the DSI to diagnose frontotemporal dementia (FTD) and Alzheimer's disease (AD). METHODS The study cohort consisted of 38 patients wit...
