We assessed the ability of the non-parametric non-uniform intensity normalization (N3) technique to correct non-uniformity in 72 volumetric brain MR scans from the preparatory phase of the Alzheimer's Disease...
we launched a multi-cohort multi-omics study characterizing the immune response in ambulatory and non-pneumonic infected individuals. With this experimental approach, we first used a well characterized, exploratory cohort of high-risk patients for hypothesis generation and subsequently confirmed...
This scaling is spatially nonuniform over the image in that different pixels with the same intensity in the original image may have different intensities in the resulting image. The goal of this scaling transformation is to produce an image on the CRT that perceptually mimics the calculated image...
Seminomatous tumours (called seminomas in the testes, dysgerminomas in the ovary and germinomas in extragonadal sites) exhibit a relatively uniform histology with a similarity to germ cell progenitors. Non-seminomatous tumours, such as yolk sac tumours (YSTs) and embryonal carcinomas (EC), ...
A method for correcting measured velocities for flow non-uniformities is introduced and application of this correction brings measured velocities within 4 m/s of the predicted value in a 1630 m/s flow. 展开 关键词: a: = frequency-modulation depth, cm~(-1) c: = speed of light in vacuum...
Another common type of transformation found between medical images is non-rigid transformation [43] [44] where, non-uniform mapping is found between the pixels/voxels of two medical images and this may occur if the patient moves his/her position during scanning or changes in the structure of ...
Moreover, the most distinctive loading cases correspond to the following characteristic values of the surrogate biaxiality ratio: β′=±∞ stand for either uniform bi-tension or bi-compression states, β′=±1 correspond to either uniaxial tension or compression, and lastly, β′=0 represents ...
A study on the analysis of O-ring under uniform squeeze rate and internal pressure by photoelastic experimental hybrid method There are three kinds of loading conditions applied to the O-ring, The first loading condition is the case in which uniform squeeze rates are applied to th... J Hawon...
Some studies have shown that the acquisition of grammar by late learners is typically less successful and produces less uniform, and perhaps even fundamentally different grammatical systems than with L1 acquisition1,2. These studies argue that the rule systems developed by late L2 learners do not ...
