Abstract:
... Electroencephography (EEG) recordings from CI listeners are contaminated by electrical artefacts that make it difficult to extract neural responses. Previously, we have removed these artefacts by means of interpolation and spatial filtering. However, the extent to which this method can effectively reduce electrical artefacts has not been fully investigated. Here, we assessed the effectiveness of i ...

Abstract:
... Development and use of global, continental, and country scale hydrological models has attracted an increasing attention over the last two decades. Though developed countries are a head in development and assessment of these models, most developing countries, if not all, even do not have their own models. Therefore, an appropriate model selection process is necessary for these regions to improve th ...

Abstract:
... Many important groundwater transport applications require solving the Darcy flow in heterogeneous porous media. Flow simulations, especially in large, highly heterogeneous aquifers, require extensive computational resources, a multiresolution (multiscale) approach to resolve the different heterogeneity scales and an accurate calculation of the velocity field. Common methods, such as finite volumes ...

Fusarium asiaticum was repeatedly isolated from blighted spikes of durum wheat with head blight-like symptoms in our experimental fields in Fukuyama, Hiroshima Prefecture in western Japan, then demonstrated to be pathogenic to the crop. F. asiaticum was not previously reported as causing head blight on durum wheat, so it has been added to the pathogens causing this disease. ...

Abstract:
... Automated Tape Placement (ATP) is one of the attractive automated composite manufacturing processes as it reduces labor cost, increases production rate and improves repeatability. In this method, the part is built by consolidating one unidirectional prepreg tape layer at a time with a placement head using a compaction roller. Defects such as gaps between neighboring tapes during lay up are inevita ...

Abstract:
... Lamins are nuclear intermediate filament proteins that play an essential role in maintaining the nuclear structure by forming a 3-D meshwork. Lamins consist of the N-terminal unstructured head, the coiled-coil rod domain, and the C-terminal tail, which is mostly unstructured except for the Ig-like domain. To date, the Ig-like domain has been characterized as a monomeric structure. Here, we determi ...

Abstract:
... Parallel compressor theory (PCT) is commonly used to estimate effects of inlet distortion on compressor performance. As well as compressor, the actual inflow to pump is also nonuniform and unfavorable for performances. Nowadays, insufficient understanding of nonuniform inflow effects on pump performance restricts its development. Therefore, this paper applies PCT to predict external characteristic ...
