- Despite the need for evidence-based practice for children with autism spectrum disorders in the community, especially in areas with a scarcity of qualified experts and high financial costs, there is a lack of evidence concerning the potential benefits of early interventions which may be affordable in the real world (e.g. low-intensity behavioral or eclectic interventions). This study examined behavioral changes in preschool-aged children with autism spectrum disorders who received low-intensity behavioral interventions (a mean of 5.5 h per week) or non-behavioral eclectic interventions delivered in community settings in Japan across a 1-year period and compared outcomes between the groups. We assessed children’s developmental quotient, adaptive behavior, autism symptom/severity, and maternal stress and depression at baseline and after 1 year. Our results revealed that children receiving interventions in their communities showed improvement in language and social development. Further, the degree of improvement in children receiving low-intensity behavioral interventions was significantly greater than in children receiving non-behavioral eclectic interventions. The improvement was associated with the intensity of total, especially one-to-one interventions. On the other hand, there were no group differences in the degree of improvement in other outcome measures. Our results suggest that some preschool-aged children with autism spectrum disorder may benefit from low-intensity behavioral interventions for their language and social development. A greater intensity of one-to-one interventions was found to be associated with greater progress in language development and communication skills. The current study highlights the importance of implementing early interventions in the community, even at a low intensity.

- We present a new analysis of multi-epoch, H-band, scattered light images of the AB Aur system. We use a Monte Carlo radiative transfer code to simultaneously model the system's spectral energy distribution (SED) and H-band polarized intensity (PI) imagery. We find that a disk-dominated model, as opposed to one that is envelope-dominated, can plausibly reproduce AB Aur's SED and near-IR imagery. This is consistent with previous modeling attempts presented in the literature and supports the idea that at least a subset of AB Aur's spirals originate within the disk. In light of this, we also analyzed the movement of spiral structures in multi-epoch H-band total light and PI imagery of the disk. We detect no significant rotation or change in spatial location of the spiral structures in these data, which span a 5.8-year baseline. If such structures are caused by disk-planet interactions, the lack of observed rotation constrains the location of the orbit of planetary perturbers to be >47 au.

- The microstructure and toughness in Fe-0.04%C-1.85%Mn-0.03%Si-0.018%Nb steel deoxidized with Ti and Zr have been studied as functions of particle characteristics, austenite grain size and soluble Ti and Zr contents using a simulated HAZ (heat affected zone) thermal cycle (peak temperature, 1 400 degrees C; peak holding time, 60 s; time of cooling from 800 to 500 degrees C, 70 s) and submerged arc welding (heat input of 15 kJ/mm), respectively. Microstructures were studied in samples containing 1.0 to 1.5 mu m-diameter oxide particles numbering 500 to 2 000 mm(-2) and with a soluble oxygen content of 10 to 30 ppm (measured before casting) and soluble Ti and Zr contents of 50-150 ppm. The gamma grain size after HAZ thermal cycle in the range between 200 and 600 mu m is controlled by pinning and solute drag. Small gamma grain size below 300 mu m was obtained with high soluble Ti and Zr contents of 110-160 ppm, whereas large gamma grain size above 300 mu m was obtained with low soluble Ti and Zr contents of 60-110 ppm. Two types of microstructures that showed high Charpy absorbed energy (vE(-10 degrees C)= 150-250 J and vE(-50 degrees C)= 50-150 J) were observed independent of gamma grain size: One is acicular ferrite and a small amount of grain boundary ferrite (GBF) and ferrite side plate (FSP) and the other is GBF, FSP and granular bainitic ferrite. It was observed that low vE(T) values are attributed to the formation of porosity, large-size particles, carbides (+nitrides) and lathe bainitic ferrite.
