The cervical uncinate process is a unique structure of the spine that undergoes significant changes in its morphological characteristics with age, and these may be related to osteoporosis. This study aimed observe distribution cancellous bone features using micro-computed tomography (Micro-CT) gain deeper understanding microstructure. We performed Micro-CT scans on 31 sets C3-C7 vertebrae, total 155 intact samples, subsequently used measurement software system obtain parameters process....

Perovskite quantum dots (QDs), emerging with excellent bright-green photoluminescence (PL) and a large absorption coefficient, are of great potential for the fabrication light sources in underwater optical wireless communication systems. However, instability caused by low formation energy abundant surface traps is still major concern perovskite-based conditions. Herein, we propose ultra-stable zero dimensional-two dimensional (0D-2D) CsPbBr3 QD/1,4-bis(4-methylstyryl)benzene (p-MSB)...

Having shown early promise, free-space optical communications (FSO) face formidable challenges in the age of information explosion. The ever-growing demand for greater channel communication capacity is one challenges. inter-channel crosstalk, which severely degrades quality transmitted information, creates another roadblock way efficient FSO implementation. Here we advance theoretically and realize experimentally a potentially high-capacity protocol that enables high-fidelity transfer an...

Purpose: Using micro-CT and finite element analysis to establish regional variation microarchitectures correlation with mechanical properties of cervical articular facet trabecular bone predict spine security material properties. Methods: A total 144 processes (each was separate four region interest (ROI), superior-anterior (SA), superior-posterior (SP), inferior-anterior (IA), inferior-posterior (IP) regions) specimens a volume 5 × mm3 were scanned by micro-CT, allowable stress other...

Abstract This study aimed to observe the distribution and morphological characteristics of trabecular bone in uncinate process cervical spine on micro-computed tomography (Micro-CT) identify microstructure process. Micro-CT scans were performed 31 sets C3-C7 vertebrae comprising 155 complete specimens. The measurement software system was used relevant parameters Trabecular mainly crisscrossed longitudinally continuous with vertebral body. There a significant difference surface area between...

Abstract Purpose To establish a finite element model of the adult cervical spine and macaque to compare stress displacement changes between two under six working conditions through analysis around characteristics facet joint, provide theoretical basis for clinical vertebral body replacement. Methods One 40-year-old volunteer one 7-year-old male were selected subjected spiral CT thin-layer scans, respectively. Moreover, original data imported into Mimics 21.0 three-dimensional model. The...

We selected 133 solar microwave bursts (SMBs) recorded by SGD and CMEs observed SOHO/LASCO from November 1999 through September 2003. These SMBs are associated with flares. analyzed the characteristics of SMBs, including duration, flux peak, burst type, spectral index. Correlated events were distinguished time location flare SMB. find that (1)The duration narrow(0°<width<20°)/normal CMEs(20°<width<120°) or slow is below 40 minutes. (2)The Halo-like CMEs(120°<width<360°)...

The cervical facet has complicated 3D microstructures and inhomogeneities. joint, which also participates in the formation, plays a certain role regulating limiting movement of spine. Correct identification evaluation its microstructure can help diagnosis orthopedic disease predict early phases fracture risk. To evaluate safety spine by measuring analyzing morphometric parameters bone trabeculae normal with high-resolution micro-computed tomography. Thirty-one sets C3 to C7 lower vertebrae...

The penetration of distributed photovoltaic in the distribution network is gradually increasing, and its impact on safe stable operation power grid increasing. At present, there are some problems network, such as insufficient reactive compensation backward voltage regulation. Moreover, communication capacity insufficient, it difficult to realize centralized control system. There a serious problem quality degradation 10kV network. In order solve above problems, this paper proposes...
