According to current theories of reading, the reader's saccades are guided primarily by spaces between words, clearly the most prominent visual feature in most modern texts. This belief was investigated by recording eye movements with unprecedented accuracy and precision while subjects read spaced and unspaced passages both silently and aloud. Modest increases in fixation durations and decrease...

Fixation instability due to saccadic intrusions is a feature of autosomal recessive spinocerebellar ataxias, and includes square wave intrusions (SWI) and macrosaccadic oscillations (MSO). A recent report suggested that the non-competitive antagonist of NMDA receptors, memantine, could decrease MSO and improve fixation in patients with spinocerebellar ataxia with saccadic intrusions (SCASI). We...

abstractwriting and speaking are the productive skills of a language and share similar components. however, there has been little attempt to investigate the impact of writing practice on the speaking proficiency of the learners. the present study using a pretest-posttest controlled group design in a quasi-experimental approach investigated the effect of guided writing practice on the speaking p...

case presentation in this report, ultrasound-guided sciatic nerve block was performed in a 25-year-old patient with tetanus to progress his respiratory drive which was decreased due to high dose sedative administration. this procedure accelerates the weaning process and extubation. introduction muscle rigidity and generalized spasm can cause severe pain in patients with tetanus. administration ...

Learning language skills in schools does not only emphasize theory, but students are required to be able use as its function. Language listening, writing, reading, and speaking a component that cannot separated from activities. The ability speak must also analyze ensure what is said can received appropriately by the listener. In fact, there still various obstacles speaking, both internal extern...

Neural activity in frontal cortical areas has been causally linked to short-term memory (STM), but whether this activity is necessary for forming, maintaining, or reading out STM remains unclear. In rats performing a memory-guided orienting task, the frontal orienting fields in cortex (FOF) are considered critical for STM maintenance, and during each trial display a monotonically increasing neu...

When reading an input tree, a bottom-up tree automaton is \unaware" of where it is relative to the root. This problem is important to the eecient implementation of decision procedures for the Monadic Second-order Logic (M2L) on nite trees. In 7], it is shown how exponential state space blow-ups may occur in common situations. The analysis of the problem leads to the notion of guided tree automa...

Background: Image-guided radiotherapy used multiple imaging during the radiation therapy course to improve the precision and accuracy of health care provider's treatment. Objectives: This study aims to assess the safety, effectiveness and economic aspects of image-guided radiation therapy for decision-making about this technology in Iran. Methods: In this study, the most important med...

conclusions the us-guided method for cvc placement was superior to the traditional landmark method in terms of access time, number of attempts, success rate, and fewer complications. objectives this study aimed to compare the traditional landmark method vs. us-guided method of cvc placement in terms of complications and success rate. patients and methods in this randomized controlled trial, pat...
