The impact of conversion feature on price discovery efficiency in the convertible bond market
Using data from Convertible bonds (CBs) issued by listed companies in China between 2019 and 2022, this study investigates the impact of the conversion feature on price discovery efficiency in the CB market. The empirical results show that permitting the conversion of CBs into shares significantly improves the efficiency of price discovery, both in terms of speed and degree. Further analysis reveals that liquidity plays a crucial role in driving this improvement.

Tailoring Ince-Gaussian arrays based on a computer-generated hologram
Abstract The continually expanding interest in Ince-Gaussian modes has arisen due to their highly complex and widely varying spatial structures, which allow these fascinating diverse light modes to be significant to various topics. In this paper, we propose a technique for generating beam arrays that contain four Ince-Gaussian modes. By utilizing a single digital hologram, the intensity distributions of each mode in the array can be manipulated independently and flexibly.
Propagation trajectory measurement and autofocusing generation of Airy beams using digital propagation
Abstract We present a method of measuring the propagation trajectory of Airy beams using digital propagation based on the theory of angular spectrum. The dependence of the transverse displacement of Airy beams on artificial propagation distance in phase masks is investigated with no motion of imaging apparatus. The parabolic propagation trajectory is experimentally verified, which is consistent with theoretical predictions.
