Acquisition-Related Morphological Variability in Structural MRI

Academic Radiology, 2006
Significant effort has been spent during the past decades to develop innovative image-processing algorithms and improve existing methods in terms of precision, reproducibility, and computational efficiency, but relatively little research was undertaken to find out the extent to which the validity of results obtained with these methods is limited by ...

Development and morphological variability of Echinococcus granulosus

Parasitology Research, 1998
Characteristics are presented of Echinococcus granulosus strobila from dogs experimentally infected with protoscolices from a single cyst isolated from the liver of a domestic pig in a central Slovakian district. Adult cestodes are characterized mainly by 28-32 hooks highly variable in shape and size; 26-51 testes situated mostly throughout the ...

VCG loop alignment and morphologic variability

Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002
The measurement of subtle beat-to-beat morphologic variability is complicated by the presence of respiration-induced movements of the heart. A statistical signal model is developed which accounts for scaling, rotation and time synchronization of a VCG loop.

Morphological variability in L2 Italian

ITL - International Journal of Applied Linguistics, 2017
AbstractKey accounts of morphological variability in L2 acquisition posit either deficits in the representation of abstract morphosyntactic features or the mapping between morpho-phonological forms and syntactic features due to computational limitations. This study extends previous research to L2 Italian, a richly inflected language. The production and

A Variable Morphological Character of Trichomonas vaginalis

Nature, 1954
SEVERAL comprehensive morphological studies of Trichomonas vaginalis have been published1. In none is mention made of a striking morphological character I have observed in three different strains of T. vaginalis. These strains were originally isolated from vaginal material gathered at the Whitechapel Clinic from patients with vaginitis and are now ...

Morphological variability of the subcallosal area of man

Surgical and Radiologic Anatomy, 2010
Knowledge of morphology of human anterior cingulate and medial frontal cortex related to the knee of corpus callosum is important in the diagnostics and neurosurgical treatment. Neuroimaging studies did not provide a clear picture of this region, what is also caused by terminological inconsistencies.

Diagnosis of Acute Leukemia: Variability of Morphologic Criteria

American Journal of Clinical Pathology, 1977
The diagnosis of acute leukemia depends on the morphologic appearance of Romanowsky-stained blast cells. Three commonly used and accepted criteria for distinguishing among blast cells of different acute leukemias are (1) nuclear chromatin pattern, (2) appearance of nucleoli, and (3) nuclear-cytoplasmic ratio.

[Morphological variability and placental function].

Gynecologie, obstetrique & fertilite, 2001
In mammals, the blastocyst defines with the maternal organism, a structure which allows embryonic development during gestation: the placenta. The structure of this organ varies remarkably across species. In this review the different type of placentation have been described in a comparative manner using terms of classification such as: placental materno-

Morphological Variability in Second Language Arabic

2017
A prominent theory of variability in L2 learners’ use of inflectional morphology is the Missing Surface Inflection Hypothesis (MSIH). The MSIH argues that morphological variability results from ‘performance limitations’ - particularly when a learner is under communication pressure (Prevost&White, 2000).
