It is difficult to deposit shape-controlled nanoparticles into a mesoporous framework while preserving the shape. For shaped platinum nanoparticles, which are typically 5-10 nm in size, capillary inclusion by sonication or the formation of a mesoporous framework around the shaped platinum nanoparticles has been attempted, but the nanoparticles aggregated or their shapes were degraded easily. In...

Vision is by far the most prevalent sense for experiencing others' body shapes, postures, actions, and intentions, and its congenital absence may dramatically hamper body-shape representation in the brain. We investigated whether the absence of visual experience and limited exposure to others' body shapes could still lead to body-shape selectivity. We taught congenitally fully-blind adults to p...

Our visual abilities are unsurpassed because of a sophisticated code for objects located in the inferior temporal (IT) cortex. This code has remained a mystery because IT neurons show extremely diverse shape selectivity with no apparent organizing principle. Here, we show that there is an intrinsic component to selectivity in IT neurons. We tested IT neurons on distinct shapes and their paramet...

The exquisite ability of primates to grasp and manipulate objects relies on the transformation of visual information into motor commands. To this end, the visual system extracts object affordances that can be used to program and execute the appropriate grip. The macaque anterior intraparietal (AIP) area has been implicated in the extraction of affordances for the purpose of grasping. Neurons in...

BACKGROUND Fifteen 3-styrylchromones were subjected to quantitative structure-activity relationship (QSAR) analysis based on their cytotoxicity, tumor selectivity and anti-HIV activity, in order to explore their biological activities. MATERIALS AND METHODS Cytotoxicity against four human oral squamous cell carcinoma (OSCC) cell lines and three human oral normal cells was determined by the 3-(...

reviews P. Yang et al. Colloidal metal nanoparticles are emerging as key materials for catalysis, plasmonics, sensing, and spectroscopy. Within these applications, control of nanoparticle shape lends increasing functionality and selectivity. Shape-controlled nanocrystals possess well-defined surfaces and morphologies because their nucleation and growth are controlled at the atomic level. An ove...

In this paper we present a scheme for accumulating local visual information in 3D, under known motion. Information about the object’s 3D shape is provided by reconstructing local contour descriptors. This shape information is accumulated over time in three ways: 1) disambiguation: erroneous stereo correspondences that are unsuccessfully tracked are discarded. We make use of aspect cues to incre...

The reversed-phase chromatographic behavior of planar and non-planar polycyclic aromatic hydrocarbons (PAHs) is investigated on tetraphenylporphyrin and two metallotetraphenylporphyrin [Sn(IV), In(III)] bonded stationary phases using methanol-water and acetonitrile-water as mixed solvent mobile phases. Large differences in the capacity factors of aromatic solute pairs having the same number of ...

An oriented attachment growth process was found for the morphology and shape control of various inorganic materials in solution-based systems. In this Article, a well-defined iron oxide polyhedron was prepared via a simple hydrothermal method. Detailed investigations revealed that the single-crystalline polyhedron evolved from polycrystalline aggregates. The shape and size control of the iron o...

The maturation of cortical Parvalbumin-positive (PV) interneurons depends on the interaction of innate and experience-dependent factors. Dark rearing experiments suggest that visual experience determines when broad orientation selectivity emerges in visual cortical PV interneurons. Here, using neural transplantation and in vivo calcium imaging of mouse visual cortex we investigate whether innat...
