Cobalt-based superalloys are common materials for the manufacturing of various components used in aerospace applications. Conventional cobalt-based with a unimodal grain structure generally exhibit low strength and ductility at high temperatures. A bimodal superalloy, Co–20Cr–15W–10Ni (CCWN), was designed to achieve both The deformation behavior tensile properties CCWN alloy fine-grain (FG), co...

PURPOSE To develop an imaging technique that maps the distribution of free cystine in the rat lens at subcellular resolution and enables cystine accumulation to be compared with the expression of the cystine-glutamate exchanger (Xc-). METHODS Whole lenses were fixed, cryoprotected, and then cryosectioned in either an equatorial or axial orientation. Sections were double labeled with either a ...

The aim of the present study was to investigate the feasibility of using ultrasonography (US) and magnetic resonance (MR) for bimodal molecular imaging of atherosclerotic neovasculature with liquid perfluorocarbon magnetic nanocapsules (NCs) targeted to vascular endothelial growth factor receptor 2 (VEGFR‑2). By incorporating perfluorooctyl bromide (PFOB) and superparamagnetic iron oxide (SPIO)...

Just after the start into new millennium concept for combined neutron and X-ray imaging was introduced by extending standard configuration of thermal NEUTRA instrument with a complementary 320 kV tube setup. Using essentially same detector both enables pixel-wise (in radiography) voxel-wise tomography) correlation combination attenuation data. The optimal use analyses such data sets depend on s...

UNLABELLED The brain basis of bilinguals' ability to use two languages at the same time has been a hotly debated topic. On the one hand, behavioral research has suggested that bilingual dual language use involves complex and highly principled linguistic processes. On the other hand, brain-imaging research has revealed that bilingual language switching involves neural activations in brain areas ...

PURPOSE In-vitro evaluation of the feasibility of 4D real time tracking of endovascular devices and stenosis treatment with a magnetic particle imaging (MPI) / magnetic resonance imaging (MRI) road map approach and an MPI-guided approach using a blood pool tracer. MATERIALS AND METHODS A guide wire and angioplasty-catheter were labeled with a thin layer of magnetic lacquer. For real time MPI ...

This paper investigates to what extent users of bilateral and bimodal fittings should expect to benefit from all three different binaural advantages found to be present in normal-hearing listeners. Head-shadow and binaural squelch are advantages occurring under spatially separated speech and noise, while summation emerges when speech and noise coincide in space. For 14 bilateral or bimodal list...

Herein, we presented a brand-new concept to construct the Forster resonance energy transfer (FRET) based cassette by integrating vibration-induced emission (VIE) chromophore as donor. Different from traditional donors only with single emission, VIE donor possessed well-separated dual bands altering excited state molecular configuration bent planar state. By linking an acceptor such cyanine dye ...
