In this study, surface-enhanced Raman spectroscopy (SERS)-encoded magnetic nanoparticles (NPs) are prepared and utilized as a multifunctional tagging material for cancer-cell targeting separation. First, silver-embedded NPs prepared, composed of an 18-nm core 16-nm-thick silica shell with silver formed on the surface. After simple aromatic compounds adsorbed NPs, they coated to provide them chemical physical stability. The resulting silica-encapsulated (M-SERS dots) produce strong SERS...
Objective: This study conducted an empirical investigation into the influence of perceived informational quality dessert café Instagram accounts on attitudes university students toward Instagram, brand perceptions, and behavioral intentions. Methods: collected 267 samples for research, reviewed reliability fitness research model, verified a total 11 hypotheses using AMOS program(26.0). Then, this used structural equations to verify hypothesis. Results: Usefulness, playfulness, information...
This paper presents a novel approach to retrieve indoor structures from raster images of complicated floor plans. We extract the building elements in plan and process them into vectorized form provide layout information. Unlike conventional approaches, proposed model is robust when recognizing rooms openings surrounded by obscuring patterns, including superimposed graphics irregular notation. To this end, we integrate various formats unified style using conditional generative adversarial...
Peptides synthesized on microbeads were encoded by chemically and physically adsorbing surface-enhanced Raman spectroscopic nanoparticles (SERS dots) the microbead surface during synthesis, which could be easily rapidly decoded spectroscopy.
Pure macroscopic single-walled-carbon-nanotube (SWNT) fibers are fabricated by using a dip-coating method without any additive or additional electrical equipment complex apparatus. The present only utilizes microfluidics, which includes capillary condensation, flow, and surface tension, results in the self-assembly self-alignment of SWNT colloids.
In this paper, we studied on the effect of organic bases in case ethylene glycol based fabrication silver nanoparticles embedded silica nanocomposite (Ag SNC) without heating. Considering their chemical structures, butylamine (BA), ethanolamine (EA), triethanolamine (TEA), tributylamine (TBA), octylamine (OA) and Jeffamine 500 (JA) were used as an base. addition, concentrations AgNO3 formation Ag SNC was also examined. conformity with characteristics SNC, SERS signal intensity benzenethiol...
Automatic floor plan analysis has gained increased attention in recent research. However, numerous studies related to this area are mainly experiments conducted with a simplified dataset low resolution and small housing scale due the suitability for data-driven model. For practical use, it is necessary focus more on large-scale complex buildings utilize indoor structures, such as reconstructing multi-use navigation. This study aimed build framework using CNN (Convolution Neural Networks)...
For autonomous robots deployed in human-populated workplaces, adhering to people's interpersonal space is a key prerequisite for safe and efficient navigation. Especially safety-critical work environments such as construction jobsites, should be capable of not only avoiding collisions but also maintaining socially acceptable distance from other workers achieve safety efficiency. However, what deemed appropriate can vary based on contexts. To this end, study aims understand the preferred...
The osteologic and myologic characteristics of the family Pentacerotidae are described in detail. Pentaceroti-dae is a monophyletic group supported by 11 synapomorphies found all members. Of their synapomorphies, two(the second infraorbital endopterygoid articulate with lateral ethmoid conditions) considerably rare percoidsand strongly support monophyly family. A comparison 44 transformation series among species revealedfour equally parsimonious trees, strict consensus tree was adopted. On...
We report a near-field two-photon excitation imaging technique for silver nanostructures to visualize optical fields in the vicinity of nanostructures. have found that image an isolated wire shows oscillating feature along long axis wire. The period oscillation is good agreement with plasmon wavefunctions resonant light. was thus attributed wavefunction. also bundles wires exhibit more intense photoluminescence signals than do wires, particularly at junctions between ends and shafts other...
We propose a new robust regression estimator using data partition technique and M estimation (DPM). The is designed to define small fixed number of subsets the partitioned set produce corresponding ordinary least square (OLS) fits in each subset, contrary resampling existing estimators such as trimmed squares estimator. proposed shares common strategy with median ball algorithm that obtained from OLS trial only on data. examine performance DPM eleven challenging sets simulation studies. also...
Abstract Roll-to-roll (R2R) gravure printing is mainly used in the manufacture of conductive lines or electronic devices because complex patterns can be printed quickly and accurately on flexible substrates using an engraved pattern roll. Gravure has several advantages including multi-layer large-area functional layers continuous production such as thin-film transistors (TFTs) circuits. Existing studies have demonstrated that quality improved by determining desired conditions coating machine...
