A facile synthesis for cyanochlorin related to chlorophyll from a formyl-substituted chlorin, by the oxidation of methyl （pyro）pheophorbide-a, was accomplished. These readily available chlorin aldehydes were assembled together with hydroxylamine hydrochloride in a tandem process to produce the corresponding chlorin nitriles in moderate to good yields. The formation of chlorin nitrile was discussed and a possible mechanism for the corresponding cyanation reaction was tentatively proposed.

As a fundamental tool in the quantum information field, quantum state tomography can be used to reconstruct any unknown state. Generally, it needs a tomographically complete set of measurements, such that all measurements are fully characterized. Here, we propose a semi-measurement-device-independent quantum state tomography protocol, which only needs one characterized measurement and a trusted ancillary system. Furthermore, we perform corresponding experiments using linear optics. Our results show that the average state fidelity is as high as 0.973, verifying the effectiveness of the scheme.

AIM: To achieve a balance between efficiency and cost in the management of medical instrument by the use of micro needle holder. METHODS: In this study, the novel multifunctional use of micro needle holders was performed between 2018 and 2019 at the Department of Ophthalmology in the 4 hospitals in Shaanxi Province. In this innovation, the micro needle holders were initially used as micro forceps to remove sutures, as eye spud to safety extract foreign body from cornea, as ciliary forceps to remove trichiasis, as well as punctal dilator to dilate most small puncta. RESULTS: Using this technique, the medical costs of both procurement and sterilization were cut off in the selected 4 hospitals. The purchase cost has dropped by roughly 50%. The sterilization cost was decreased by about 30%. CONCLUSION: The innovation in the five-in-one multifunctional use of micro needle holders saves the medical costs.

In the past decade, thanks to the powerfulness of deep-learning techniques, we have witnessed a whole new era of automated code generation. To sort out developments, we have conducted a comprehensive review of solutions to deep learning-based code generation. In this survey, we generally formalize the pipeline and procedure of code generation and categorize existing solutions according to taxonomy from perspectives of architecture, model-agnostic enhancing strategy, metrics, and tasks. In addition, we outline the challenges faced by current dominant large models and list several plausible directions for future research. We hope that this survey may provide handy guidance to understanding, utilizing, and developing deep learning-based code-generation techniques for researchers and practitioners.
