In this paper, we propose an effective AMC using deep learning (DL) for flexible and adaptive OFDM-based optical networks. The proposed DL-based AMC is able to classify four typical modulation schemes such as binary phase-shift keying (BPSK), quadrature PSK (QPSK), 8-PSK, and 16- quadrature amplitude modulation (QAM) in dynamic network conditions.

Radio over Fiber (RoF) stands as a cuttingedge technology poised to revolutionize emerging wireless networks, especially in the context of fifth-generation Cloud-Radio Access Networks (C-RAN). Concurrently, with the pervasive integration of deep learning across diverse domains such as communication and data processing, this investigation delves into the nonlinear effects observed in a fronthaul interface.

This paper proposes a 3-phase 2-level inverter configuration combined with a buck DC-DC converter to improve the switching loss of semiconductor devices. Compared to the traditional 3-phase 2-level inverter configuration, this configuration can reduce the number of switching times on the inverter side by about 2/3 compared to the sine Pulse Width Modulation technique (sine PWM) and 1/2 compared to the Discontinuous PWM (DPWM).

The paper proposed a method to reduce the effect of nonlinear distortion in 16-APSK OFDM system, which is a pilot-based automatic phase shift at the receiver. Transmitted pilot is inserted during the OFDM modulation process in the transmitter. When the pilot passes through the HPA, information about the nonlinear distortion of the HPA will be carried

This paper combines a heterodyne interferometer and a real-time SDR phase meter, demonstrating an ultrasonic vibration instrument’s high-speed vibrating measurement capabilities. A double-pass interferometer is implemented to produce interference signals modulated with a sine waveform phase change associated with a tool’s ultrasonic vibrating displacement, calculated by the phase meter’s quadrature demodulation algorithm.

Ebook "Fluorescence spectroscopy in biology: Advanced methods and their applications to membranes, proteins, dna, and cells" focuses on two new approaches in cell fluorescence microscopy. R. Brock shows how to characterize diffusion in cells by fluorescence correlation spectroscopy. The last two contributions by S. Rosenthal and O. Minet are devoted to photophysics and the use of quantum dots in cell imaging.

The three-phase six-switches voltage source inverter is usually used for industrial motor control and renewable energy systems. However, in order to decrease to size and cost of the drive systems, the three-phase four-switch voltage source inverter has been applied to low-cost motor control and renewable energy system.

Although the prognosis of locally advanced cervical cancer has improved dramatically, survival for those with stage IIIB-IVA disease or lymph nodes metastasis remains poor. It is believed that the incorporation of intensity-modulated radiotherapy into the treatment of cervical cancer might yield an improved loco-regional control, whereas more cycles of more potent chemotherapy after the completion of concurrent chemotherapy was associated with a diminished distant metastasis.

The gut microbiome plays an important role in immune modulation. Specifically, presence or absence of certain gut bacterial taxa has been associated with better antitumor immune responses. Furthermore, in trials using fecal microbiota transplantation (FMT) to treat melanoma patients unresponsive to immune checkpoint inhibitors (ICI), complete responses (CR), partial responses (PR), and durable stable disease (SD) have been observed.

Efforts have been made to investigate the role of salvage radiotherapy (RT) in treating recurrent ovarian cancer (ROC). Stereotactic ablative radiation therapy (SABR) is a state-of-the-art therapy that uses intensity modulation to increase the fractional dose, decrease the number of fractions, and target tumors with high precision.

This paper proposes an novel simple anti-bias modulation technique for single phase Dual-Active-Bridge DC/DC converters. When a pulsating load occurs, the control efforts of the controller lead to sudden changes in the phase shift. In turn, this cause a momentary unbalance in the positive and negative volt-second product of the transformer.

This paper presents an effective grid-injected power control method for a photovoltaic (PV) system using the theory of model predictive control (MPC). The system consists of two power converters including a DC/DC boost converter for maximum point point tracking (MPPT) and a DC/AC converter formed by a two-level voltage-source three-phase inverter.

This paper presents a new pulse width modulator control method using the offset function to reduce switching loss in five-level Cascade inverter. The proposed technique is based on the offset function being 3rd harmonic voltage. The offset voltage will be added to the control voltages so that the voltage of phase which has absolute of load current largest move into top or bottom of the carriers.

RAD140 (Testalone) is a novel selective androgen receptor modulator with very limited data currently available on adverse effects related to this compound. The first-in-human phase 1 trial was recently published and did report a significant proportion of elevated aspartate aminotransferase, alanine transaminase, and total bilirubin among the test subjects.
