Monolithic electric field control of a grating coupler for finely tuning wavelength, efficiency, and bandwidth

Yifan Zhang, Yongyong Zhuang, Liu Yang, Xin Liu et autres

-On-Insulator (PIN-PMN-PTOI) based apodized grating coupler through finite-difference time-domain (FDTD) simulations. By leveraging the ultrahigh electro-optic coefficient of PIN-PMN-PT single crystal, we demonstrate precise control over the effective refractive index, thereby fine-tuning the central wavelength, enhancing coupling efficiency (CE) and 3-dB bandwidth. …

Skywork-Math: Data Scaling Laws for Mathematical Reasoning in Large Language Models -- The Story Goes On

Liang Zeng, Liangjun Zhong, Liang Yu Zhao, Tianwen Wei et autres

In this paper, we investigate the underlying factors that potentially enhance the mathematical reasoning capabilities of large language models (LLMs). We argue that the data scaling law for math reasoning capabilities in modern LLMs is far from being saturated, highlighting how the …

Demonstration of a bandwidth-tunable optical passband filter with tunable attenuation

Zhilin Yuan, Wei Li, Rui Yang, Liu Yang et autres

A bandwidth-tunable optical passband filter with tunable attenuation is proposed. The filter, composed of a transmission liquid crystal array and high-resolution diffraction grating, was successfully demonstrated based on the compact spatial light design. Experimental results showed that the bandwidth, wavelength, and attenuation …

Dexmedetomidine inhibits Tetrodotoxin-resistant Nav1.8 sodium channel activity through Gi/o-dependent pathway in rat dorsal root ganglion neurons

Xiyao Gu, Benlong Liu, Kaikai Zang, Liu Yang et autres

BACKGROUND: Systemically administered dexmedetomidine (DEX), a selective α2 adrenergic receptor (α2-AR) agonists, produces analgesia and sedation. Peripherally restricted α2-AR antagonist could block the analgesic effect of systemic DEX on neuropathic pain, with no effect on sedation, indicating peripheral analgesic effect of DEX. …
