The brain areas involved in visual word processing rapidly become lateralized to the left cerebral hemisphere. It is often assumed this is because, in the vast majority of people, cortical structures underlying language production are lateralized to the left hemisphere. An alternative hypothesis, however, might be that the early stages of visual word processing are lateralized to the left hemis...

nanocomposites made of carbon nanotube (cnt) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness.  in this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated.  first, fea models are created consisting of cnts with different shapes of straight and rope-...

the usage and production of polychlorinated biphenyls (pcbs) was banned in argentina in2002, approximately twenty to thirty years later than in other countries. a total of 29 sediment samples (upto 14 m deep) were analyzed for a mix of seven individual pcbs in a time series for over more than one year in twelve selected locations, including harbors, recreational docks and several industrialized...

Melt electrowriting (MEW) is an electrohydrodynamic process capable of producing organized patterns micrometer-scale polymer fibers. Integrating MEW with other additive manufacturing technologies, such as extrusion-printing or bioprinting, offers tantalizing possibilities for multi-scale biofabrication anatomically shaped scaffolds. However, introducing 3D structures onto the conventionally fla...

The right cerebral hemisphere may be relatively specialized for parsing simple visual stimuli according to default rules, such as the Gestalt laws of perceptual organization, whereas the left cerebral hemisphere may be relatively specialized for overriding such default rules. We extend this model to 'semantically rich domains' by performing a divided-visual-field experiment on 16 chessmasters. ...

Introduction Due to structural characteristics of the visual pathways, stimuli that are presented in the right half of the visual field (RVF) are initially projected to the left cerebral hemisphere, while those presented in the left half of the visual field (LVF) are projected to the right cerebral hemisphere. This anatomical feature has frequently been taken to support the notion that the well...

we report an unusual case of hemimegalencephaly (hmg) associated with ipsilateral congenital-infiltrating lipomatosis of the face in a five-month-old boy. hemimegalencephaly is a rare but unique malformation characterized by enlargement of all or parts of a cerebral hemisphere. the affected hemisphere may have focal or diffuse neuronal migration defects, with areas of polymicrogyria, pachygyria...

Abstract. Cordillera Darwin in Tierra del Fuego (Chile) remains one of the least studied glaciated regions world. However, this region being very few terrestrial sites at latitude Southern Hemisphere has potential to provide key information on effect climate variability and change cryosphere sub-polar mid-latitudes Hemisphere. Schiaparelli Glacier is located northern side draining north Monte S...

One major problem of the conventional solar cells is low conversion efficiency. In this work, we have proposed a new design including hemisphere texturing on top and metallic plasmonic nanostructure under the silicon layer to enhance the optical absorption inside the photosensitive layer.    The finite-difference time-domain (FDTD) method has been used to investigate the interaction of light wi...
