The immobilization of proteins on gold-coated magnetic nanoparticles and the subsequent recognition targeted provide an effective means for separation via application a filed. A key challenge is ability to fabricate such with desired core−shell nanostructure. In this article, we report findings fabrication characterization iron oxide (Fe2O3 Fe3O4) core@shell (Fe oxide@Au) toward novel functional biomaterials. hetero-interparticle coalescence strategy has been demonstrated fabricating Fe...
The natural gradient learning method is known to have ideal performances for on-line training of multilayer perceptrons. It avoids plateaus, which give rise slow convergence the backpropagation method. Fisher efficient, whereas conventional not. However, implementing method, it necessary calculate information matrix and its inverse, practically very difficult. This article proposes an adaptive directly obtaining inverse matrix. generalizes Gauss-Newton algorithms provides a solid theoretical...
Synthesis of nanomaterials with multi-imaging modality is great importance in clinical molecular imaging and diagnostics. This work reports novel synthetic strategy to create ultrasmall hexagonal upconversion nanoparticles (UCNPs), β-NaGdF4: Yb3+, Er3+, Tm3+, inherent magnetic efficient properties. The use new combination lanthanide chloride sodium TFA as the precursors for UCNPs gave best results terms size (10−40 nm), crystallinity morphology, proved be cost- time-saving. Water...
An ultrastretchable triboelectric nanogenerator is developed by simultaneous transfer printing. The demonstrates all-in-one, self-powered touch, motion and force sensing that can function as artificial skin for soft robotic components.
Synthesis of biologically active antibody conjugated quantum dots (QDs) has been great importance in cellular imaging and diagnostics. Cetuximab (or Erbitux) is the first monoclonal drug which targets epidermal growth factor receptor (EGFR) overexpressed most cancer cells. In present work, we investigated three different conjugation strategies to obtain functional QD−cetuximab conjugates for tumor-specific imaging. Successful cetuximab QDs was achieved using PEG polymer-coated two long-chain...
The parameter spaces of hierarchical systems such as multilayer perceptrons include singularities due to the symmetry and degeneration hidden units. A space forms a geometrical manifold, called neuromanifold in case neural networks. Such model is identified with statistical model, Riemannian metric given by Fisher information matrix. However, matrix degenerates at singularities. singular structure ubiquitous not only but also gaussian mixture probability densities, ARMA time-series many...

Ni–nitrilotriacetic acid (NTA) functionalized CdSe/ZnS quantum dots (QDs) were exploited as a site-specific labeling agent of histidine-tagged biomolecules in live cells; the QDs found to be water-soluble, aggregation free and stable for several months.
Although recent studies on object recognition using deep neural networks have reported remarkable performance, they usually assumed that adequate size and image resolution are available, which may not be guaranteed in real applications. This paper proposes a framework for recognizing objects very low images through the collaborative learning of two networks: enhancement network network. The proposed attempts to enhance extremely into sharper more informative with use signals from trained...
A ceramic core employed in a single-crystal casting process should endure for long time at temperatures above 1500 °C. Therefore, this work, an inorganic binder was applied to conventional injection-molding method produce having enough strength during the process. The starting powders used mixture of three kinds fused silica with particle sizes 117 μm, 33 and 17 zircon flour 10 silicon carbide 16 μm. mixed powder coated precursor then dried 80 °C 1 h. wax injection molded. injected...
Abstract To be able to produce ceramic bodies with complex shapes without interlayer delamination and warping through vat photopolymerization‐based 3D printing techniques, photosensitive slurries should studied prepare printed green sintered bodies. In this study, we developed dual curable acrylate–epoxide for digital light processing (DLP) printing. The curing process of the is a combination photo‐radical polymerization acrylate thermal cationic cyclo‐aliphatic epoxide. prepared by showed...
Abstract Four kinds of azo dyes and their metal-azo were synthesized in order to obtain a high reflective index better thermal stability as recording material for DVD-R.
