ion With traces of category exemplars stored in SM, what is the effect of a probe with a category name? To find out, 3, 6, and 9 high-level distortions of three category prototypes were generated. Each was combined with its category name, and one copy was stored in SM, as just described, for a total of 18 memory traces. Testing was then carried out using each of the three category names as prob...

New ultrafast gradient systems and hybrid imaging sequences make it possible to acquire a complete image in real time, without the need for breathholding or electrocardiogram (ECG) triggering. In 21 patients, left ventricular function was assessed by the use of a turbo-gradient echo technique, an echo-planar imaging (EPI) technique, and a new real-time imaging technique. End-diastolic and end-s...

Background: The magnetic resonance imaging (MRI)-based radiotherapy planning method have been considered in recent years because of the advantages of MRI and the problems of planning with two images modality. The first step in MRI-based radiotherapy is to evaluate magnetic resonance (MR) images geometric distortion. Therefore, the present study aimed to evaluate system related geometric distort...

The main text assumes stability of the open loop system, both to guarantee the existence of the xed point x̄, and to justify the application of the Nyquist criterion. Here we argue that this condition holds for networks trainable by Echo State protocol [1] or by FORCE [2]. The terms "echo state property" and "fading memory property" coined in [1] refer to the requirement for globally convergent ...

INTRODUCTION: Proton Echo-Planar Spectroscopic Imaging (PEPSI) provides fast spatial-spectral encoding and has been demonstrated to map a variety of metabolites in the human brain [1,2]. Further acceleration in PEPSI can be accomplished by using parallel imaging along the phaseencoding dimension(s) [3,4]. However, the acceleration is limited by the relatively low SNR of the metabolites and g-fa...

INTRODUCTION AND OBJECTIVES To determine whether the reproducibility of left ventricular outflow tract (LVOT) area measurement is greater with three-dimensional echocardiographic (3D-echo) planimetry than with conventional 2D-echo. To determine the LVOT circularity index by means of 3D-echo. To determine the usefulness of measuring the LVOT area by 3D-echo for quantifying the severity of valvul...

[1] A technique for the estimation of humidity in the lower troposphere using simultaneous dual‐wavelength radar observations is proposed and tested. The method compares the reflectivity from clouds and precipitation of a non‐attenuated wavelength (S‐band, 10 cm) and an attenuated wavelength (Ka‐band, 8 mm) to compute the clear‐air gaseous attenuation at the attenuated wavelength. These estimat...

PURPOSE To compare the sensitivity of conventional spin-echo, fast spin-echo, fast fluid-attenuated inversion recovery (FLAIR), and turbo gradient spin-echo MR sequences in the detection of multiple sclerosis lesions. METHODS Conventional spin-echo, fast spin-echo, fast FLAIR, and turbo gradient spin-echo sequences were performed on a 1.0-T MR imager in seven patients with clinically definite...
