为提高锆(Zr)合金的抗高温水蒸气性能,采用磁控溅射技术,通过改变沉积过程中的N2流量,在Zr合金表面制备不同Cr/N比的涂层,研究不同N含量对涂层结构和抗高温水蒸汽氧化性能的影响。利用扫描电镜、能谱仪、X射线衍射仪对涂层氧化前后的表面与截面形貌、化学组成、相结构进行观察和分析,利用纳米压痕仪测量涂层的力学性能,通过高温水蒸汽氧化试验评估涂层的抗氧化性能。结果表明,随N含量的增加,涂层的生长结构分别为"疏松柱状"、"致密非柱状"、"致密柱状"。其中,"致密非柱状"结构的涂层具有最高的硬度,是"疏松柱状"涂层的2倍。同时,该涂层在氧化过程中生成的Cr2O3氧化层均匀致密,可以有效防护Zr合金基底6h不被氧化。

A microwave power-combining system composed of two Panasonic 2M244-M1 magnetrons based on master–slave injection-locking is demonstrated in this paper. The principle of master–slave injection-locking and the locking condition are theoretical analyzed. Experimental results are consistent with the theoretical analysis and the experimental combined efficiency is higher than 96%. Compared with the external-injection-locked system, the power-combining based on the master–slave injection-locking magnetron is superior by taking out the external solid-state driver and the real-time phase control system. Thus, this power-combining system has great potential for obtaining a high efficiency, high stability, low cost, and high power microwave source.

We propose and experimentally demonstrate a novel physical layer encryption scheme for high-speed optical communication. A 10 Gb/s on-off keying signal is secretly transmitted over 100 km standard single-mode *** intensity-modulated message is secured by the encryption mechanism, which is composed of an external noise source and an internal time-delayed feedback loop. The external noise serves as an entropy source with sufficient randomness. The feedback loop structure in the transmitter introduces a time-domain encryption key space, and a corresponding open-loop configuration at the receiver side is used for synchronization and *** results show the effectiveness of the proposed scheme. For a legitimate terminal, bit error rate below10-8 can be obtained. Decryption degradations with the mismatch of different hardware parameters are researched. The time delay in the feedback loop provides a sensitive encryption key. For other hardware parameters,the system is robust enough for synchronization. Meanwhile, the time-delay signature of the loop is able to be well concealed by the external noise. Moreover, the proposed scheme can support density wavelength division multiplexing transmission with a relatively simple structure. This work also provides a new concept to establish optical secure communication by combining a time-delayed feedback chaotic system and random noise.

Association of peripheral blood biomarkers with response to anti-PD-1 immunotherapy for patients with dMMR metastatic colorectal cancer: a multicenter cohort study

Background: The Aspergillus is known to predominantly affect the immunocompromised host, but it is rare to cause acute invasive pulmonary aspergillosis(IPA) in immunocompetent hosts which is invariably fatal. Here we report a case of acute IPA in an immunocompetent patient after cleaning air filtration with no underlying disease. This is the first case in the literature about cleaning air filtration induced pulmonary *** presentation: An immunocompetent 41-year-old man presented with several days history of fever and productive cough with respiratory distress. These symptoms were unresponsive to treatments for pulmonary bacterial infection. He was exposed to air conditioning dust during cleaning air filtration. Computed tomography images revealed the characteristic tree-in-bud pattern along the bronchus and bronchiolitis associated with thickened bronchial walls. Later the galactomannan(GM) test in BALF was positive. So we performed empirical antifungal treatment with intravenous voriconazole 400 mg/d for 4 months. The patient recovered after antifungal therapy. Later microbiological examination of the BALF revealed growth of A. fumigatus *** :In cases of pulmonary dysfunction after cleaning air filtration, with tree-in-bud pattern along the bronchus and bronchiolitis associated with thickened bronchial walls on the CT, clinicians should consider aspergillus inhalation as an aetiology, and early antifungal therapy is recommended. And we should consider an occupational hazard for air conditioning sweeper.
