Distinctive messages in infant-directed lullabies and play songs.

Mothers were recorded singing a song of their choice in both a lullaby style and a play-song style to their 6-month-olds. Adult raters identified the play-song-style and lullaby-style versions with 100% accuracy. Play-song-style renditions were rated as being more brilliant, clipped, and rhythmic and as having more smiling and more prominent consonants. Lullaby-style renditions were characterized as being more airy, smooth, and soothing. Adults observed videotapes (without sound) of 6-month-olds listening to alternating lullaby-style and play-song-style trials and performed at above chance levels when determining which music the infants were hearing. Coding analyses revealed that infants focused their attention more toward themselves during lullaby-style trials and more toward the external world during play-song-style trials. These results suggest that singing may be used to regulate infants' states and to communicate emotional information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

MSTP在随需应变中走向成熟

基于SDH之上的MSTP技术目前已经成为运营商建设多业务城域传送网的主要选择。随着技术的不断发展和新业务的层出不穷，MSTP产生了许多新的变化和趋势。一方面，围绕数据业务的优化改进，促使一系列新技术如LCAS、GFP、MPLS、RPR不断走向商用；另一方面如何与即将开展的大规模3G传输网络建设相结合、如何为3G业务提供更好的传送通道，已经成为MSTP当前需要重点考虑的问题。从光网络的发展趋势来看，在光传送网中引入控制平面，通过ASON来快速提供新业务，并实现业务的端到端调度和保护，将是MSTP发展的重要方向。     

J-substitution algorithm in magnetic resonance electrical impedance tomography (MREIT): phantom experiments for static resistivity images

Recently, a new static resistivity image reconstruction algorithm is proposed utilizing internal current density data obtained by magnetic resonance current density imaging technique. This new imaging method is called magnetic resonance electrical impedance tomography (MREIT). The derivation and performance of J-substitution algorithm in MREIT have been reported as a new accurate and high-resolution static impedance imaging technique via computer simulation methods. In this paper, we present experimental procedures, denoising techniques, and image reconstructions using a 0.3-tesla (T) experimental MREIT system and saline phantoms. MREIT using J-substitution algorithm effectively utilizes the internal current density information resolving the problem inherent in a conventional EIT, that is, the low sensitivity of boundary measurements to any changes of internal tissue resistivity values. Resistivity images of saline phantoms show an accuracy of 6.8%-47.2% and spatial resolution of 64 x 64. Both of them can be significantly improved by using an MRI system with a better signal-to-noise ratio.     

碳含量及终轧、卷取温度对DI材Δr值的影响

对于低碳铝镇静钢 DI材试验及统计分析结果表明 ,在一定范围内 ,碳含量增高 ,材质面内各向异性减小而趋向于均匀化 ;终轧温度升高 ,材质面内各向异性值则增大 ;卷取温度的影响亦具有类似的规律性。拉伸试验和断面金相分析结果进一步证实 ,较高碳含量和适当的热轧温度可抑制晶粒过分长大 ,缩小晶粒间差异 ,达到改善材质面内各向异性的目的。     

硬盘消失之谜

羡慕我吧？最新的H55主板加i5661。由于不太玩3D游戏,所以并没有搭载独立显卡,不过硬盘倒是挂得满满的。因为咱是高清玩家,所以硬盘里塞满了30Mbps以上的高清电影。3个500GB的硬盘和三个1TB的硬盘几乎都要被填满了,于是最近又加了一个新的1TB硬盘,装在了第三方芯片组控制的两个SATA接口上。     

Nitrogen budget for the Oldman River Basin, southern Alberta, Canada

The Oldman River Basin (OMRB), located in southern Alberta (Canada), with an area of 28,200 km², is mainly forested in its western part and is used for intensive agriculture in its eastern part. The objective of this paper is to estimate the nitrogen (N) budget for the Oldman River Basin as a whole and its sub-basins, and to discuss differences in the N budget between various sub-basins. Better knowledge of the N budget in this watershed may be also utilized for understanding N dynamics in similar watersheds within semi-arid climatic regions. The model used is a mass-balance spreadsheet model that takes into account N inputs and N export through surface water. During the last 120 years, anthropogenic N inputs to the OMRB have increased circa 40 fold. By the end of the 20th century, the OMRB received an annual N input of about 5174 kg N km⁻² yr⁻¹, whereas only about 25 kg N km⁻² yr⁻¹ were exported via riverine flow. For the sub-basins, annual N inputs ranged from 2516 to 19011 kg N km⁻² yr⁻¹, and annual N export via riverine flows varied between 6 and 277 kg N km⁻² yr⁻¹. Over 85% of total N inputs to the OMRB are due to anthropogenic activities, including manure (55%), synthetic fertilizer (27%), and N fixation on agricultural lands (4%). Sewage accounted for less than 1%, and N inputs from atmospheric deposition and fixation in forests represented 6 and 8% respectively. Despite increasing anthropogenic N inputs, N export with riverine flow currently accounts for only 1% of the inputs, indicating that most of the N inputs are currently retained in the OMRB or are re-emitted into the atmosphere.
