Purpose: Various noise sources affect BOLD fMRI time-courses and limit the benefits of high field fMRI. The aim of the present study was to investigate the contribution and the origin of non-thermal noise to fMRI signal fluctuations in the visual cortex at 7T during rest. The following noise sources were considered: 1) low frequency drifts; 2) effects related to the phase of respiration and car...

gestational choriocarcinoma usually occurs following an intrauterine pregnancy. we report a case of metastatic choriocarcinoma to the left kidney and lungs with long term intermittent amenorrhea and vaginal bleeding after a normal vaginal delivery. a 43 year old rural woman presented with three years intermittent amenorrhea and vaginal bleeding following normal vaginal delivery. she also compla...

Objective: In order to evaluate the endometrium by ultrasound in patients undergoing controlled ovarian hyperstimulation (COH) with clomiphene citrate (CC) and human menopausal gonadotropin (HMG) with intrauterine insemination (IUI) to determine the relationship between endometrial pattern and thickness on pregnancy rate (PR). Methods: In this prospective study, 108 infertile couples under...

As in vision, acoustic signals can be reflected by a smooth surface creating an acoustic mirror image. Water bodies represent the only naturally occurring horizontal and acoustically smooth surfaces. Echolocating bats flying over smooth water bodies encounter echo-acoustic mirror images of objects above the surface. Here, we combined an electrophysiological approach with a behavioral experiment...

Collatz dynamic systems present a statistical space that can be studied rigorously. In previous study, the author presented in unique numerical mode by tabulating sequential correlation pattern of division 2 function’s even numbers until became odd with consecutive occurrence, following an attribute 50:50 probability once (ascending behavior) as opposed to more than (descending behavior). this ...
