The effects of Y and Nb addition on thermal stability, glass-forming ability (GFA), magnetic softness Co75B25 metallic glass (MG) were comprehensively investigated. experimental results indicated that the GFA, studied MGs increase in order < Co73Nb2B25 Co71.5Y3.5B25 Co69.5Y3.5Nb2B25. structural origins improved properties revealed by ab initio molecular dynamics (AIMD) simulations density funct...

AIM The aim of this study was to compare visually guided ocular motor behaviour in children with visual processing and/or motor deficits with an age-matched comparison group and an adult group. METHOD Visual stimuli were shown to 28 children with visual processing and/or motor deficits (11 females, 17 males; mean age 7y 5mo, SD 2y 9mo, range 2-14y;) and an age-matched comparison group of 213 ...

BACKGROUND The neural substrate for clinical symptoms and neuropsychological performance in individuals with attention-deficit/hyperactivity disorder (ADHD) has rarely been studied and has yielded inconsistent results. We sought to compare the microstructural property of fibre tracts associated with the prefrontal cortex and its association with ADHD symptoms and a wide range of attention perfo...

The formation of S-hydroxymethylglutathione from formaldehyde and glutathione is a central reaction in the consumption of the cytotoxin formaldehyde in some methylotrophic bacteria as well as in many other organisms. We describe here the discovery of an enzyme from Paracoccus denitrificans that accelerates this spontaneous condensation reaction. The rates of S-hydroxymethylglutathione formation...

We perform molecular dynamics simulations to compress binary hard spheres into jammed packings as a function of the compression rate R, size ratio α, and number fraction x(S) of small particles to determine the connection between the glass-forming ability (GFA) and packing efficiency in bulk metallic glasses (BMGs). We define the GFA by measuring the critical compression rate R(c), below which ...

The fract ional a lliso tropy (FA ) value for Diffusion Tensor Imagillg is widely Ilsed to del.crminc t.he anisotrop~' of di fl'usioll in a given voxel. As the FA value is based on the tensor's eigenvectors it is not possible to calculate this quantity for I-IARDI dif1'tlsion profil es. III t his paper we introduce an anisotropy index for HARDI data that utilizes the L-norm as the most na tural...

Abstract A series of Zr-based glasses has been obtained by rapid melt quenching and their thermal characteristics ( T g , x l ) were determined DSC/DTA. Some the most recognized glass forming ability (GFA) criteria applied to predict alloys study its dependence on alloy composition. As a result, best compositions among studied could be selected. It was found that as general trend an increase Zr...

One of the major challenges for Internet-of-Things applications is that existing cellular technologies do not support uplink IoT traffic in an energy-efficient manner. There are two principal ways serving traffic: grant-based (i.e., scheduled) and grant-free random access). Grant-based access provides fine-grained control reliability latency at cost energy consumption required signaling. Grant-...

The objective of this study was to investigate whether it is possible to pool together diffusion spectrum imaging data from four different scanners, located at three different sites. Two of the scanners had identical configuration whereas two did not. To measure the variability, we extracted three scalar maps (ADC, FA and GFA) from the DSI and utilized a region and a tract-based analysis. Addit...
