Referent systems, originally introduced in Vermeulen (1995) as a tool for text semantics, can also be used as a tool for modeling sentential semantics. As formulated by Vermeulen, they provide a reasonable means to model the basic sentences of languages like English (where the verb sits in a medial position and can identify its arguments based on their direction) on the one hand, and languages ...

The cardiorespiratory effects of raising patients from the supine to the sitting position for neurosurgery were investigated. The change caused marked decreases in cardiac index, stroke volume, PaO2 and Qs/Qt, with a significant increase in (PAO2-PaO2) and total peripheral resistance. It is concluded that patients who maintain normotension in the sitting position do not necessarily have an adeq...

twenty six patients with double elevator palsy (dep) (ranging from 25-90 pd), who had undergone either callahan or knapp-modified-kanpp procedure from february, 1981 to february, 1994, were reviewed. we achieved acceptable results in correction of hypotropia in primary position. three patients gained peripheral fusion and after reviewing the results we concluded that in patients having large-an...

OBJECTIVES To evaluate the effect of posture change from the supine to the sitting position and before and after passive leg raising on maternal functional hemodynamics in pregnant women at 35-37 weeks' gestation, and to compare the changes in pregnancies that subsequently developed pre-eclampsia (PE) or gestational hypertension (GH) with those that remained normotensive. METHODS In 2764 sing...

Latent class models provide a useful framework for clustering observations based on several features. Application of latent class methodology to correlated, high-dimensional ordinal data poses many challenges. Unconstrained analyses may not result in an estimable model. Thus, information contained in ordinal variables may not be fully exploited by researchers. We develop a penalized latent clas...

Classification images provide an important new method for learning about which parts of the stimulus are used to make perceptual decisions and provide a new tool for measuring the template an observer uses to accomplish a task. Here we introduce a new method using one-dimensional sums of sinusoids as both test stimuli (discrete frequency patterns [DFP]) and as noise. We use this method to study...

results 22 patients were male (73.3%) and the mean age was 60.3 ± 10.6 years in our study group. the most common artery for cut off and run off was superior femoral artery in both assessments. proximal section of each artery was the most common anatomical section for cut off and run off. there was a same report of cut off artery by mr-angiography and surgery (kappa coefficient of agreement was ...

The representations that mediate the coding of spatial position were examined by comparing the behavior of patients with left hemispatial neglect with that of nonneurological control subjects. To determine the spatial coordinate system(s) used to define "left" and "right," eye movements were measured for targets that appeared at 5 degrees, 10 degrees, and 15 degrees to the relative left or righ...

objective: elevated nucleated red blood cell (nrbc) count is introduced as a potential marker of intra-uterine growth restriction (iugr). to investigate the probable association regardless of any known underlying disease, we aimed to study disturbances in nrbc count in infants experiencing idiopathic iugr. materials and methods: twenty three infants regarded iugr without any known cause were ch...
