Distinct patterns of neural activity during memory formation of nonwords versus words

Research into the neural underpinnings of memory formation has focused on the encoding of familiar verbal information. Here, we address how the brain supports the encoding of novel information that does not have meaning. Electrical brain activity was recorded from the scalps of healthy young adults while they performed an incidental encoding task (syllable judgments) on separate series of words and "nonwords" (nonsense letter strings that are orthographically legal and pronounceable). Memory for the items was then probed with a recognition memory test. For words as well as nonwords, event-related potentials differed depending on whether an item would subsequently be remembered or forgotten. However, the polarity and timing of the effect varied across item type. For words, subsequently remembered items showed the Usually observed positive-going, frontally distributed modulation from around 600 msec after word onset. For nonwords, by contrast, a negative-going, spatially widespread modulation predicted encoding success from 1000 rnsec onward. Nonwords also showed a modulation shortly after item onset. These findings imply that the brain supports the encoding of familiar and unfamiliar letter strings in qualitatively different ways, including the engagement of distinct neural activity at different points in time. The processing of semantic attributes plays an important role in the encoding of words and the associated positive frontal modulation

The postnatal support needs of mothers with an intellectual disability

OBJECTIVE: there is growing evidence that many parents with intellectual disabilities can parent successfully when given adequate support. This paper aims to explore the postnatal care experiences of mothers with an intellectual disability. DESIGN: a qualitative design was used and data were collected using a semi-structured interview format and analysed using Interpretative Phenomenological Analysis. SETTING: the study took place in community settings in Scotland. PARTICIPANTS: six mothers with intellectual disabilities were interviewed about their experiences. MEASUREMENTS AND FINDINGS: two super-ordinate themes are discussed with accompanying subthemes: challenges of providing support and how support was delivered. KEY CONCLUSIONS: the mothers valued formal postnatal care, but this was secondary to informal support. How mothers perceived the support impacted on its effectiveness and building effective relationships with professionals presented challenges. IMPLICATIONS FOR PRACTICE: the study suggests the structure and quality of the wider support networks of mothers with an intellectual disability are central and should be taken account of by professionals. Providing information and advice in ways that validates the mother's role is also important, particularly as the mother's perception of how help is given can impact on the degree to which mothers engage with professional

Study of the damping characteristics of general aviation aircraft panels and development of computer programs to calculate the effectiveness of interior noise control treatment, part 1

Tests were carried out on 20 inch x 20 inch panels at different test conditions using free-free panels, clamped panels, and panels as installed in the KU-FRL acoustic test facility. Tests with free-free panels verified the basic equipment set-up and test procedure. They also provided a basis for comparison. The results indicate that the effect of installed panels is to increase the damping ratio at the same frequency. However, a direct comparison is not possible, as the fundamental frequency of a free-free panel differs from the resonance frequency of the panel when installed. The damping values of panels installed in the test facility are closer to the damping values obtained with fixed-fixed panels. Effects of damping tape, stiffeners, and bonded and riveted edged conditions were also investigated. Progress in the development of a simple interior noise level control program is reported

Search for Higgs Bosons Decay H→γγH\to \gamma\gamma Using Vector Boson Fusion

The sensitivity of the ATLAS experiment to low mass SM Higgs produced via Vector Boson Fusion mechanism with $H\to \gamma\gamma$ is invest igated. A cut based event selection has been chosen to optimize the expected signal significance with this decay mode. A signal significance of 2. 2$\sigma$ may be achieved for M_H=130 \gev with 30 fb$^{-1}$ of accumulated luminosity
