A fundamental issue in neural coding is the role of spike timing variation in information transmission of sensory stimuli. Vestibular afferents are particularly well suited to study this issue because they are classified as either regular or irregular based on resting discharge variability as well as morphology. Here, we compared the responses of each afferent class to sinusoidal and random hea...

pore network modeling uses a network of pores connected by throats to model the void space of a porous medium and tries to predict its various characteristics during multiphase flow of various fluids. in most cases, a non-realistic regular lattice of pores is used to model the characteristics of a porous medium. although some methodologies for extracting geologically realistic irregular network...

This 30-year-old male patient attended the emergency department because of dizziness accompanied by selfassessed regular pulse rates of 30–40 bpm. Physical examination was normal but cardiac auscultation revealed frequent premature beats. A subsequent 12-lead ECG documented the arrhythmia (Fig. 1). Similar episodes had occurred 12 months ago but thorough cardiac evaluation, including echocardio...

objectives: to evaluate the reliability of head and trunk acceleration measured by mtx sensors during walking on level and irregular surfaces and to compare the differences between healthy young and old adults. methods: participants were 20 young female university students and 20 non-faller elderly women in iran, 2013. two mtx sensors were used to measure head and trunk accelerations in the ver...

We report the performance of two aphasic patients in a morphological transformation task. Both patients are Spanish-Catalan bilingual speakers who were diagnosed with agrammatic Broca's aphasia. In the morphological transformation task, the two patients were asked to produce regular and irregular verb forms. The patients showed poorer performance with irregular than regular morphological transf...

Compositionality is a critical and universal characteristic of human language. It is found at numerous levels, including the combination of morphemes into words and of words into phrases and sentences. These compositional patterns can generally be characterized by rules. For example, the past tense of most English verbs ("regulars") is formed by adding an -ed suffix. However, many complex lingu...

The proposition that the mental lexicon is a ‘dual route’ system, advanced by Pinker and others to account for regular and irregular morphology, overlooks the important fact that morphological regularity correlates inversely with phonological regularity --‘regular’ past-tense beeped being phonologically irregular (exceptional syllable), while ‘irregular’ past-tense kept is phonologically just r...

The current study examines the neural correlates of 8-to-12-year-old children and adults producing inflected word forms, specifically regular vs. irregular past-tense forms in English, using a silent production paradigm. ERPs were time-locked to a visual cue for silent production of either a regular or irregular past-tense form or a 3rd person singular present tense form of a given verb (e.g., ...

The objective of this study was to assess the nutritional adequacy of sub-elite runners with irregular menstrual function (n=10) and that of a comparable group of runners with regular menstrual function (n=10), with a special focus on vitamin E. Based on 3 days' records of weighed dietary intake, the mean energy intakes of micro- and macronutrients were estimated. Both estimated daily energy in...
