in this paper, a method for automatic stitching of radiology images based on pixel features has been presented. in this method, according to the smooth texture of radiological images and in order to increase the number of the extracted features after quality enhancement of initial radiology images, 45 degree isotropic mask is applied to each radiology image to observe the image details. after t...

microfabrication applications, it is widely used to transfer the designed patterns from an etching mask to the substrate. When the sample is immersed into the etching bath, the etchant only contacts and reacts with the substrate surfaces where are uncovered by the etching mask. The suitable materials for the mask can be polymers or other materials such as photoresist, SU-8,SiO2 andSi3N4, which ...

Argon fluoride laser (ArF) lithography using immersion technology has the potential to extend the application of optical lithography to 45 nm half-pitch and possibly beyond. By keeping the same 4x magnification factor, the dimensions of the structures on masks are becoming comparable to the exposure wavelength or even smaller. The polarization effect induced by mask features is, however, an iss...

Introduction Steady-state diffusion-weighted imaging enables high-SNR, high-resolution diffusion images of brain and is potentially effective in the diagnosis of stroke location [1]. However, white matter anisotropic tissue contrast can mask out a real stroke location. In order to get rid of the anisotropic effect of diffusion, the whole diffusion tensor is acquired and its trace is derived. Al...

patients and methods sixty children aged between 2 and 12 years, and scheduled for on-pump surgery due to a congenital heart disease were randomly assigned into two groups. oral midazolam (0.5 mg/kg up to 15 mg per patient) and dexmedetomidine (2 µg/kg) were administered 45 minutes pre-anesthesia. children’s anxiety, mask acceptance behavior, hemodynamic measures, and cardiopulmonary outcomes w...

This paper presents an interactive on-line wet etch simulator (SEGS) which predicts the etched shape as a function of time for arbitrary isotropic or anisotropic etchants and any initial mask shape. Using any Java-enabled web browser users can draw initial masks, choose the etchant, simulate the etching, and view animation results. SEGS can be accessed at http://mira.me.tuns.ca/

OBJECTIVE To investigate the compressive force applied to the head during mask ventilation and determine whether this force increases in response to an attempt to correct the mask leak. METHODS The authors asked 24 participants (consultants, fellows and nurses) to administer positive pressure ventilation to a modified leak-free, term newborn manikin using a self-inflating bag (SIB) and a Neop...
