LDPC-Coded Generalized Frequency Division Multiplexing for Intensity-Modulated Direct-Detection Optical Systems by Dong Guo, Wei Zhang, Feng Tian, Jianyang Shi, Kaihui Wang, Miao Kong, Junwen Zhang, Kai Lv, Deng'ao Li, Xiaolong Pan, Xiangjun Xin

“…In this paper, a low-density parity check (LDPC) coded GFDM with high-level modulation scheme is proposed for more flexible and advanced multicarrier modulation in intensity-modulated/direct-detection (IM/DD) optical systems. Then, we experimentally demonstrate an LDPC-coded GFDM with 16-quadrature amplitude modulation (16QAM) system transmitted over 20-km standard single-mode fiber at different symbol rates to verify the applicability of the proposed scheme. …”

Multi-Channel Optical Coherence Elastography Using Relative and Absolute Shear-Wave Time of Flight. by Eli Elyas, Alex Grimwood, Janine T Erler, Simon P Robinson, Thomas R Cox, Daniel Woods, Peter Clowes, Ramona De Luca, Franco Marinozzi, Jérémie Fromageau, Jeffrey C Bamber

“…Shear-wave time of arrival (TOA) was detected by tracking the axial OCT-speckle motion using cross-correlation methods. Shear-wave speed was then calculated from inter-channel differences of TOA for a single burst (the relative TOA method) and compared with the shear-wave speed determined from positional differences of TOA for a single channel over multiple bursts (the absolute TOA method). …”

Objective optical densitometry-based evaluation of longitudinal changes in the inflammatory process in the treatment of bacterial keratitis by I.S. Alifanov, N.G. Klopotska

“…Results: At presentation and days 7 and 14 of treatment, the average median (interquartile range [IQR]) COD value for the affected eyes was 92.8 (55.6-99.6), 89.7 (51.1-97.3) and 80.6 (32.0-93.1) grayscale units (GSU), respectively (p < 0.05), indicating a decrease in inflammatory infiltration, and the average mean (SD) COD value for the control eyes was 19.6 ± 3.0, 19.9 ± 2.8, and 19.7 ± 2.6 GSU, respectively, with no statistically significant difference. Conclusion: The use of optical densitometry for monitoring corneal transparency in eyes treated for BK over a two-week period enabled objective recording of a gradual reduction in median (IQR) COD values in the affected eyes from 92.8 (55.6–99.6) to 80.6 (32.0–93.1) GSU, corresponding to an improvement in the clinical status of patients.…”
