Stop-signal inhibition disrupted by damage to the right inferior frontal gyrus in humans.

by Adam R Aron , Paul C Fletcher , Ed T Bullmore , Barbara J Sahakian , Trevor W Robbins - Nature Neuroscience , 2003
"... The precise localization of executive functions such as response inhibition within the prefrontal cortex (PFC), although theoretically crucial, has proven to be controversial and difficult 1 . Functional neuroimaging has contributed importantly to this debate Go/no-go and stop-signal tasks require ..."

SPM96 (Wellcome Department of Cognitive Neurology, London) with cost-function masking 9 . MRIcro was used to trace five ROIs: medial frontal (MED), orbital frontal gyrus (ORB), inferior frontal gyrus (IFG), middle frontal gyrus (MFG) and superior frontal gyrus (SFG) onto the standard SPM T1 template

This thesis presents a new active mask (AM) framework and an algorithm for segmenta-tion of digital images, particularly those of punctate patterns from fluorescence microscopy. Fluorescence microscopy has greatly

Sequence-independent segmentation of magnetic resonance images

by Bruce Fischl, David H. Salat, A Nikos Makris, Florent Ségonne, B Brian T. Quinn, Anders M. Dale A - Neuroimage , 2004
"... We present a set of techniques for embedding the physics of the imaging process that generates a class of magnetic resonance images (MRIs) into a segmentation or registration algorithm. This results in substantial invariance to acquisition parameters, as the effect of these parameters on the contras ..."

on the contrast properties of various brain structures is explicitly modeled in the segmentation. In addition, the integration of image acquisition with tissue classification allows the derivation of sequences that are optimal for segmentation purposes. Another benefit of these procedures is the generation

Model-based fault detection and diagnosis: status and applications

by Rolf Isermann - In Proceedings of the 16th IFAC Symposium on Automatic Control in Aerospace, St , 2004
"... Abstract: For the improvement of reliability, safety and efficiency advanced methods of supervision, fault detection and fault diagnosis become increasingly important for many technical processes. This holds especially for safety related processes like aircraft, trains, automobiles, power plants and ..."

and chemical plants. The classical approaches are limit or trend checking of some measurable output variables. Because they do not give a deeper insight and usually do not allow a fault diagnosis, model-based methods of fault detection were developed by using input and output signals and applying dynamic

Procedure to detect anatomical structures in optical fundus images

by unknown authors
"... We present an overview of the design and test of an image processing procedure for detecting all important anatomical structures in color fundus images. These structures are the optic disk, the macula and the retinal network. The algorithm proceeds through five main steps: (1) automatic mask generat ..."

Adaptive Template Matching with Shift-Invariant Semi-NMF

by Jonathan Le Roux, Alain De Cheveigné, Lucas C. Parra
"... How does one extract unknown but stereotypical events that are linearly superimposed within a signal with variable latencies and variable amplitudes? One could think of using template matching or matching pursuit to find the arbitrarily shifted linear components. However, traditional matching approa ..."

A Systematic Approach to Signal Space Detection

by Taehyun Jeon, Jaekyun Moon - IEEE Trans. Magn , 1997
"... A general procedure is developed to implement the fixed delay tree search (FDTS) detector in the multi-dimensional signal space. The procedure systematically finds a required set of hyperplanes that divide the entire space into different decision regions. A Boolean mapping function is also analytica ..."

A meta-analytic review of obesity prevention programs for children and adolescents: The skinny on interventions that work.

by Eric Stice , Heather Shaw , C Nathan Marti - Psychological Bulletin, , 2006
"... This meta-analytic review summarizes obesity prevention programs and their effects and investigates participant, intervention, delivery, and design features associated with larger effects. A literature search identified 64 prevention programs seeking to produce weight gain prevention effects, of wh ..."

potential confounding variables at baseline (with sufficiently large sample sizes), it should therefore minimize the chances that any of these confounding variables are correlated with treatment condition, which should thus maximize the ability to detect intervention effects if they really occur (i

Visual Neuroscience Is Suppression Just Normal Dichoptic Masking? Suprathreshold Considerations

by Alexandre Reynaud , Robert F Hess , Robert F Hess
"... PURPOSE. Amblyopic patients have a deficit in visual acuity and contrast sensitivity in their amblyopic eye as well as suppression of the amblyopic eye input under binocular viewing conditions. In this study we wanted to assess the origin of the amblyopic suppression by studying the contrast percep ..."

that observed for our controls. This occurs under conditions in which there should be no dichoptic masking. Furthermore, the matching contrast could be well predicted by the monocular contrast sensitivity. Altogether, this suggests that amblyopic suppression cannot be explained by normal dichoptic masking
