C-Band 200 Gbit/s/λ PS-PAM-8 Transmission Over 2-km SSMF for Optical Interconnections by Xuancheng Huo, Meng Xiang, Gai Zhou, Jilong Li, Jianping Li, Yuwen Qin, Songnian Fu

“…In comparison with the uniformly distributed eight-level pulse amplitude modulation (PAM-8) signal, a certain generalized mutual information (GMI) gain can be experimentally achieved utilizing Optimized pairwise Maxwell-Boltzmann PAM-8 (Optimized PMB-PAM-8) with derived PMF under the condition of same bit-rate. After 2-km standard single-mode fiber (SSMF) transmission, the net data rate can be increased from 197 Gbit/s of uniformly distributed PAM-8 to 212 Gbit/s by the use of Optimized PMB-PAM-8, which can satisfy the requirement of 200G per lane optical interconnections.…”

Time-Interleaved SAR ADC with Background Timing-Skew Calibration for UWB Wireless Communication in IoT Systems by Kiho Seong, Dong-Kyu Jung, Dong-Hyun Yoon, Jae-Soub Han, Ju-Eon Kim, Tony Tae-Hyoung Kim, Woojoo Lee, Kwang-Hyun Baek

“…To demonstrate the effectiveness of the proposed technique, intensive works were performed, including the design of a 7-bit, 2.5 GS/s 5-channel time-interleaved SAR ADC and various simulations, and the results prove excellent efficacy of signal-to-noise and distortion ratio (SNDR) and spurious-free dynamic range (SFDR) of 40.79 dB and 48.97 dB at Nyquist frequency, respectively, while the proposed window detector occupies only 6.5% of the total active area, and consumes 11% of the total power.…”

Vitamin D status in children aged 0 to 3 years living in Moscow. Treatment and prevention of vitamin D deficiency by M. V. Mozzhukhina, I. N. Zakharova

“…The seasonal factor does not have a significant effect on the serum calcidiol level (r = 0.06 at p = 0.3), which may be due to the peculiarities of the specific prevention of hypovitaminosis: a bit more than a third of children take vitamin D in summer (39.2%), whereas absolute majority (83.3%) take it in winter.…”
