Background Previous studies indicated that long coronary lesions are one of the key predictors of drug-eluting stent （DES） failure. The purpose of this study was to evaluate the efficacy and the safety of the long length FIREHAWK stent in long coronary artery disease. Methods The long cohort of TARGET I was a prospective, multicenter, single arm trial. It was planned to enroll 50 patients undergoing percutaneous coronary intervention （PCI） for the treatment of de novo long lesions in a native coronary artery. The major inclusion criteria of the trial was that patients were intended to undergo the treatment of a long target lesion（s） with diameter stenosis 〉70% and reference vessel diameter 2.5 mm to 4.0 mm by visual estimate, that needed to be covered by at least one 33 mm or 38 mm stent or multiple long stents overlapped. The angiographic follow-up was planned at 9-month and the clinical follow-up will be up to 5 years. The primary end point was in-stent late lumen loss at 9-month. Results Fifty patients （mean age （57.6±10.2） years） with 59 de novo long lesions （reference vessel diameter （2.85±0.44） mm, lesion length （35.2±9.4） mm, and stent length （41.8±11.3） mm） were enrolled. The angiographic follow-up rate was 92% at 9-month. The in-stent late loss was （0.16±0.16） mm. Proximal edge, distal edge and in-segment late loss （mm） were 0.21±0.35, 0.03±0.33, and 0.07±0.26, respectively. No in-segment binary restenosis was observed. At 1-year no death, Q wave myocardial infarction （MI）, or stent thrombosis occurred. Non-Q-wave MI occurred in two patients （4%） due to procedural complications. Conclusions Treatment of long coronary lesions with the FIREHAWK stent is able to produce similar results as observed in the FIREHAWK~ FIM clinical trial. Based on this result, we are confident in the treatment prospect of the FIREHAWK for long coronary lesions.

Hybrid quantum system of negatively charged nitrogen–vacancy（NV^-） centers in diamond and superconducting qubits provide the possibility to extend the performances of both systems. In this work, we numerically simulate the coupling strength between NV^-ensembles and superconducting flux qubits and obtain a lower bound of 1016cm^（-3） for NV^-concentration to achieve a sufficiently strong coupling of 10 MHz when the gap between NV^-ensemble and flux qubit is 0. Moreover, we create NV^-ensembles in different types of diamonds by14^（N＋）and12（C＋）ion implantation, electron irradiation, and high temperature annealing. We obtain an NV^-concentration of 1.05 × 1016cm^（-3） in the diamond with1-ppm nitrogen impurity, which is expected to have a long coherence time for the low nitrogen impurity concentration. This shows a step toward performance improvement of flux qubit-NV^-hybrid system.

基于粒球计算的粗糙集理论作为知识发现和数据挖掘的重要工具之一,已成功地应用于标记预测、属性约简等。而现有的粒球粗糙集模型仅仅是从单粒度出发,无法从多粒度角度对数据进行分析和处理,实际生活中仍有很多应用场景需从多粒度角度进行思考。将粒球计算思想结合到多粒度粗糙集模型,提出了多粒度粒球粗糙集模型,并讨论了该模型的相关性质。该模型通过纯度的设定对数据进行粒球划分,能够有效地刻画数据之间的内在联系,以此设计多粒度粒球粗糙集的正域生成算法。实验分析表明该模型的可行性和有效性。

The Institute of High Energy Physics, Chinese Academy of Sciences have designed a new type of photomultiplier tube(PMT) based on microchannel plates(MCPs) with large area photocathode, known as large area microchannel plate photomultiplier tube(MCP–PMT). The aging characteristics of the large area MCP–PMTs are different from dynode PMTs and small proximity-focus MCP–PMT. In this work, a prototype large area MCP–PMT was aged by operating with nearly 1000 photoelectrons per pulse for 3 months, and aging process of the MCP–PMT was discussed based on the aging curve.
