Radio signal classification has a very wide range of applications in the field wireless communications and electromagnetic spectrum management. In recent years, deep learning been used to solve problem radio achieved good results. However, data currently is limited scale. order verify performance learning-based on real-world data, this paper we conduct experiments large-scale ACARS ADS-B with sample sizes 900,000 13,000,000, respectively, categories 3,143 5,157 respectively. We use same...
Abstract Due to the unique microstructures and components of extracellular matrix (ECM), decellularized scaffolds had been used widely in clinical. The reaction host toward depends on their biocompatibility, which should be satisfied before applied aim this study is develop a xenograft material with good biocompatibility for further bone repair, an effective gentle method. existing chemical physical decellularization techniques including ethylene diamine tetraacetic acid (EDTA), sodium...
This study examines the backscattered ultrasound (US) and back-propagating photoacoustic (PA) signals from trabecular bones, their variations with reduction in bone minerals collagen content. While status is directly related to strength of bone, diagnosis its condition using US remains a challenge.For both PA methods, coded-excitation matched filtering were utilized provide high sensitivity detected signal. The optical source was 805-nm CW laser employing 2.2-MHz ultrasonic transducer. Bone...
Trauma or infections associated critical bone defects lead to a huge economic burden in the healthcare system worldwide. Recent advances tissue engineering have led potential new strategies for repair, replacement, and regeneration of defects, especially biomaterials decellularization protocols from xenogenic tissues. However, complexity structure mechanical environment limits synthesis artificial with biomaterials. Thus, purpose our study is develop natural scaffold great...
We used ultrasound (US) and photoacoustic (PA) imaging modalities to characterize cattle trabecular bones. The PA signals were generated with an 805-nm continuous wave laser for optimally deep optical penetration depth. detector both was a 2.25-MHz US transducer lateral resolution of ∼1 mm at its focal point. Using pixel size much larger than the trabeculae, raster scanning images related averaged values thermoelastic properties, as well density measurements in volume. backscatter yielded...
Non-invasive, portable, economical, dynamic blood glucose monitoring device has become a functional requirement for diabetes in his regulating entire life. In photoacoustic (PA) multispectral near-infrared diagnosis system, the aqueous solutions was excited by low power (order of milliwatts) CW laser whose wavelengths were from 1500 to 1630 nm. The be analyzed contained within cell (PAC). PA signals measured using piezoelectric detector, and then voltage detector amplified with precision...
The paper presents modifications of the sine-approximation method (SAM) specified in ISO 16063-11:1998, focusing on two various well-established versions: (i) SAM version using heterodyne quadrature signals (HQS) and (ii) time interval analysis (TIA), their implementation national medium-frequency vibration standard NIM, China. For HQS version, modified techniques procedures have been introduced applicable to suppress disturbing effects from frequency instability carrier signal displacement...
In the fields of military and civil uses, some special passages exist in many major parts, such as non-linear tubes. The overall performance is usually decided by surface quality. Abrasive flow machining (AFM) technology can effectively improve quality parts. order to discuss mechanism abrasive nonlinear tube, nozzle picked up researching object, self-designed polishing liquid employed make research on key technological parameters linear tube. Technological parameters’ impact parts through...
The interaction between magnetic quantum emitters and the local electromagnetic environment is a promising method to manipulate spontaneous emission. However, it severely limited by weak interactions component of light natural materials. Herein, we demonstrate that special type anapole states associated with “onefold” electric toroidal dipole moment can be excited efficient silver oligomers. Based on states, radiative power effectively suppressed significant coupling emitter nonamer,...
Photoacoustic spectroscopy has been proved to be a potential method for noninvasive blood glucose detection. We used 1535 nm pulsed laser excite photoacoustic signal in solution and then explored the influence of different concentration on analyze sensitivity at this wavelength. designed simple cell structure, which focused ultrasonic transducer receive signals, so as reduce attenuation. In terms results, we have found that high-concentration solutions, results strong linearity...
Neuroblastoma is a highly lethal childhood tumor derived from differentiation-arrested neural crest cells. Like all cancers, its growth fueled by metabolites obtained either circulation or local biosynthesis. Neuroblastomas depend on polyamine biosynthesis, with the inhibitor difluoromethylornithine showing clinical activity. Here we show that such inhibition can be augmented dietary restriction of upstream amino acid substrates, leading to disruption oncogenic protein translation,...
Among numerous mature optical 3D measurement techniques, phase-shift profilometry (PSP) has been widely used because of its high precision and insensitivity to ambient light, high-speed PSP become a research hotspot in recent years. Current mainstream high-frame rate projection techniques employ binary defocusing schemes, which limit the available depth. We propose rate, large-depth-range sinusoidal fringe technique based on step-designed LED chips array. In principle, one hand, array still...
Phase measuring deflectometry (PMD) has been extensively applied to measure specular surfaces due its non-contact, high-precision, full-field measurement capabilities. Liquid crystal display (LCD) screen is the most common structured light source in PMD. However, response time of liquid molecules limits frame rate around 100 frames per second (fps). Therefore, it quite difficult for traditional PMD rapidly moving surfaces. This paper proposes a 3D dynamic sensing technique, microsecond-PMD...
