Word reading and reading comprehension: stability, overlap and independence

Reading and Writing, 2007
Longitudinal twin data were analyzed to investigate the etiology of the stability of genetic and environmental influences on word reading and reading comprehension, as well as the stability of those influences on their relationship. Participating twin pairs were initially tested at a mean age of 10.3 years, and retested approximately five years later ...

Etiology of the Stability of Reading Difficulties: The Longitudinal Twin Study of Reading Disabilities

Twin Research and Human Genetics, 2007
AbstractResults obtained from previous longitudinal studies of reading difficulties indicate that reading deficits are generally stable. However, little is known about the etiology of this stability. Thus, the primary objective of this first longitudinal twin study of reading difficulties is to provide an initial assessment of genetic and environmental

Prediction and Stability of Reading Problems in Middle Childhood

Journal of Learning Disabilities, 2013
The longitudinal prediction of reading problems from fourth grade to sixth grade was investigated with a sample of 173 students. Reading problems at the end of sixth grade were defined by significantly below average performance (≤ 15th percentile) on reading factors defining word reading, fluency, and reading comprehension.

Boosted sensing for enhanced read stability in STT-MRAMs

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
Read access in STT-MRAMs is well known to be highly sensitive to process variations. Such variations are responsible for read bit error rates that are worse than conventional CMOS memories (e.g., SRAM) by orders of magnitude, especially at low voltages.

SRAM Cell With Better Read and Write Stability With Minimum Area

TENCON 2019 - 2019 IEEE Region 10 Conference (TENCON), 2019
This paper describes a novel SRAM architecture to improve read and write stability. Read stability is enhanced by increasing $\beta$ ratio to 4 and write stability is enhanced by storage node charging and discharging through two transistors. The proposed 8T SRAM architecture is compared with Conventional 6T, decoupled 8T SRAM cell and 10T SRAM cell ...

STT-RAM read stability in DRAM operating region

2015 15th Non-Volatile Memory Technology Symposium (NVMTS), 2015
Spin-transfer-torque RAM (STT-RAM) is the most promising candidate for replacing DRAM while gaining an additional function of non-volatility. The relationship between rapid increase of spin-inversion current and stability of read operation (read disturbance) in the DRAM-array operating time region of less than 10 ns (i.e., "fast" region) was examined ...

Ocular Dominance Stability and Reading Skill: A Controversial Relationship

Optometry and Vision Science, 2011
ABSTRACT Purpose. Evidence is mixed concerning the relationship between stability of ocular dominance and reading deficits. Contrasting results may be due to the use of different tests of dominance, different samples of readers, and different scoring methods.

High Read Stability and Low Leakage Cache Memory Cell

2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007
Data in conventional six transistor (6T) static random access memory (SRAM) cells are vulnerable to noise due to the direct access to the data storage nodes through the bit lines during a read operation. A new nine transistor (9T) SRAM cell is proposed in this paper for simultaneously enhancing read stability and reducing leakage power consumption. The

THE STABILITY OF BINOCULAR FIXATION DURING READING IN ADULTS AND CHILDREN

Developmental Medicine & Child Neurology, 1993
SUMMARYThe authors recorded the binocular eye‐movements of children and adults while they read single words appropriate for their reading ability. Normal data were obtained from nine‐ to 11‐year‐old primary‐school children and adults, because very little is known about changes in binocular vergence during reading.

Electrical Stability (Read and Write Operations)

2011
In SRAM, read and write are fundamental operations. To ensure the correct operations, the stability analysis is indispensable. In this chapter, electrical stability analysis is explained. In Sect. 3.1, the SRAM operations, read and write, are explained. In this section, the read stability, static-noise margin SNM, and the write stability are described.
