Top row: (a) a brain image (I1) with a predefined ROI; (b) I1 after a simulated 29.2% atrophy of the ROI (I2); (c) deformed I1 to I2 using IRG overlaid by the simulated ROI. Bottom row: log Jacobian of the simulated transformation by IRG. Deformation Based Morphometry with Implicit Reference-Based Registration: Validation and Detection of Structural Changes in a Primate Model of Early-Life Stress

Introduction: fMRI studies generally employ gradient-echo (GE) BOLD contrast due to the limited signal change and signal-to-noise ratio (SNR) of spin echo (SE) BOLD contrast at standard field strength. Ultra-high field (7T) provides increased BOLD contrast-to-noise ratio (CNR) and decreases the contribution that large vessels make to GE BOLD contrast, due to higher capillary contribution and th...

Le présent article se propose d’analyser les différents aspects de la crise présents dans pièce Roi, le rat et fou du Roi Matéi Visniec. Dans cette grotesque, on passe d’une monarchie, située un univers à fois carnavalesque révolutionnaire, une l’humanité société démocratique. La folie des dirigeants, dégénérescence société, parole manipulation l’Histoire, qui est au service politique, tels son...

alain robbe-grillet nous offre une modalité très représentative de la mise en abyme. la mise en abyme est un procédé dans lequel un récit  est emboîté dans un autre récit. en effet, à la lecture des gommes, nous constatons qu’il a inclus l’histoire d’œdipe-roi et en a fait une intrigue policière. c’est donc à la lumière de cette micro histoire  que la tragédie grecque est démythifiée. la mise e...

• ROI and the financial analysis of the benefits of training is not always the most important factor in evaluation, but it is certainly one amongst many important factors which can be considered. • ROI is not essential or even necessary for every form of training, but it is vital in many cases. • ROI and Kirkpatrick’s model of evaluation are not mutually exclusive; in fact I deem that both are ...

BACKGROUND AND PURPOSE Second harmonic imaging (SHI) is a novel ultrasound technique that allows the evaluation of brain tissue perfusion. The purpose of this study was to assess normal cerebral echo contrast characteristics in 3 regions of interest (ROIs) in the transverse axial and coronal insonation planes through the temporal bone window. Materials and Methods- SHI examinations were perform...

We aimed to evaluate the precision and longitudinal sensitivity of measurement of bone mineral density (BMD) in the pelvis and to determine the effect of bone cement on the measurement of BMD in femoral regions of interest (ROI) after total hip arthroplasty (THA). A series of 29 patients had duplicate dual-energy x-ray absorptiometry (DXA) scans of the hip within 13 months of THA. Pelvic analys...

Several services today are annotated with points of interest (PoIs) such as “coffee shop”, “park”, etc. A region of interest (RoI) is a neighborhood that contains PoIs relevant to the user. In this paper, we study the scenario where a user wants to identify the best RoI in a city. The user expresses relevance through a set of keywords denoting PoIs. Ideally, the RoI should be small enough in si...
