We propose a novel chromatic dispersion (CD) estimation method by fractional Fourier transformation of linear-frequency modulation (LFM) signals. This method can measure inband and outband CD without using extra spectrum or timeslot resourses. In our method, LFM signals are added on quadrature phase...

Conclusion: This study discovered potential biomarkers that affected carotid plaque progression and macrophage regulation at the single-cell level, and examined their regulatory roles in immune regulation, programed cell death (PCD), and inflammatory factor modulation.

Modulation format identification (MFI) is necessary for future elastic optical networks. We propose an MFI scheme based on the amplitude deviation analysis of the received optical communication signal. In our method, for a received optical signal, two values of normalized average amplitude deviation...

Conventional fast Fourier transform based frequency offset estimation (FFT-FOE) algorithm is suitable for QPSK and 8&#x002F;16&#x002F;64QAM signals. However, due to the non-rectangular distribution of constellation points, the conventional FFT-FOE is not suitable for 32-QAM signal. In this p...

Reactive oxygen species (ROS) are central to the progression of alcoholic fatty liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD). In ALD, ROS arise from alcohol metabolism (CYP2E1 and ADH/ALDH2), causing oxidative damage and fibrosis. In NAFLD, mitochondrial dysfunction, ER stress, a...

We demonstrate a Gb/s real-time visible light communication (VLC) system based on NRZ-OOK by a phosphorescent white light-emitting diode (LED). We propose an equalizer employed by an RC series-parallel connection cascade circuit based on the T-bridge structure. With the proposed circuit, the 3-dB ba...

Aeromonas hydrophila isolates from clinical cases (n=43) were tested against 8 antimicrobial agents and typed by outer membrane protein (OMP) pattern by using sodium dodecyl sulfate gel electrophoresis. All isolates were resistant to ampicillin (MICs, ≥16 μg mL−1) and sulfamonomethoxine (MICs, ≥64 μ...

We design a quadrature phase-shift keying training sequence (QPSK-TS) for monitoring both optical signal-to-noise ratio (OSNR) and chromatic dispersion (CD) in a dense wavelength division multiplexing (DWDM) system. By applying fast Fourier transform on the QPSK-TS, a comb-like spectrum with discret...
