以MCP为基底的CSI光电阴极的研究

紫外辐射一般较弱,在大气中传输衰减较厉害,提高光电阴极量子效率是紫外探测技术的关键。通过对不同基底上光电阴极的分析和实验,得出以MCP为基底的光电阴极在发射模式为反射式时,量子效率高﹑制作工艺简单。并确定了CsI光电阴极厚度与MCP的规格参数的关系。

Extended mobile-host-centric transport protocol

In wireless networks, data packets are lost due to channel interference and fading rather than network congestion. Thus, TCP designed for wired networks, cannot achieve a satisfying performance in wireless networks. Utilizing a cross-layer mechanism to identify the course of packet loss, we have proved that a mobile-host-centric transport protocol (MCP) can achieve higher throughput than TCP Reno and New Reno in static wireless environment. In this paper, we extend the cross-layer feedback mechanism and con...

Effects and complications of placement of motility coupling post in porous polyethylene orbital implants

Objective: To investigate the effects and complications of primary and secondary placements of motility coupling post (MCP) in the unwrapped porous polyethylene orbital implant (PPOI) following enucleation. Methods: We investigated 198 patients who received PPOI implantation following the standard enucleation procedure in the First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, China, from 2002 to 2004. These patients were subgrouped into PPOI-only patients (112 cases, received PPOI following enucleation), primary MCP patients (46 cases, received primary placement of MCP during PPOI operation), and secondary MCP patients (40 cases, received secondary placement of MCP 6 months after the initial surgery). Effects and complications among these three groups were compared. Results: The PPOI-only patients took shorter treatment course when compared with other two MCP groups (P<0.001), without significant difference noted between the two MCP groups. However, the two MCP groups had better prosthetic motility than PPOI-only group (P<0.001), without significant difference between the two MCP groups. In the early stage, 2 eyes in the PPOI-only group and 1 eye in the primary MCP group had PPOI infection. In PPOI-only group, 3 (2.68%) eyes had PPOI exposure, which occurred after fitting the prostheses; 4 eyes (8.70%) in primary MCP group and 1 eye (2.50%) in secondary MCP had PPOI exposure, which occurred before fitting the prostheses. After prosthesis was fit successfully, the excessive discharge and granuloma were 33.9% and 1.79% in PPOI group-only, 53.3% and 8.9% in primary MCP group, and 52.5% and 7.5% in secondary MCP group, respectively. Conclusion: Both primary and secondary placements of MCP into the PPOI following enucleation can help patients to obtain desirable prosthetic motility, but maybe associated with more complications. The primary placement of MCP with skilled operation in selected patients is more recommendable than secondary placement.

“三泵集成”打造海洋CO2负排放生态工程

微型生物(包括细菌、古菌和病毒)是海洋碳循环的巨大幕后推手,在全球气候变化中发挥了举足轻重的作用。大气二氧化碳(CO_2)由海洋藻类生物转变成可沉降有机组分(生物泵),经过细菌和古菌及其他生物和病毒作用(微型生物碳泵),在广阔水体中产生的惰性有机碳(RDOC)可在千年时间尺度上被封存,其伴随颗粒物进一步沉降到海底由底栖微生物作用变成碳酸盐矿物(碳酸盐碳泵)得以更长时间尺度的封存。文章在充分了解海洋微生物过程和机制的基础上,阐述"三泵(生物泵、微型生物碳泵、碳酸盐碳泵)集成"的固碳、储碳原理和优势;采用人工智能手段,制定海洋负排放工程可行性方案,为海洋碳封存提供可监测、可报告、可核查的理论依据和实验场景。从科学原理上,该方案的实施将可望助力我国2060年实现碳中和的宏伟目标。
