Abstract： Bio-ethanol reforming for hydrogen production, using renewable raw materials and adopting mature and efficient chemical processes, is an important source of green hydrogen supply to achieve the goals of carbon peaking and carbon neutrality. Bio-ethanol is a widely used substitute for fossil fuels. With the continuous progress of cellulosic ethanol technology in recent years, bio-ethanol will gradually break through the constraints of starch-based raw material supply. Based on the industrialization achievements of hydrogen production and bio-ethanol, bio-ethanol reforming can realize a rapid linkage with the existing hydrogen energy industry. However, the existence of a carbon#2;carbon signal bond in ethanol poses new challenges to the development of hydrogen production catalysts, and production technology for the palladium membrane reactor has been significantly improved, creating an opportunity for the miniaturization of equipment and on-line application of bio-ethanol reforming. Bio-ethanol can be supplied through gas stations, and online hydrogen production can avoid the potential safety hazards of hydrogen storage and transportation. Bio-ethanol reforming for online hydrogen production is expected to achieve a seamless replacement of fuel vehicles in the process of industrialization, which has broad market prospects and great strategic significance.

Abstract： 以往关于时间与金钱奖励选择问题的探讨主要从员工工龄视角着手。但这一视角不能直接解释外部环境资源短缺时, 员工对时间与金钱奖励选择偏好的差异问题。本文依据生命史理论, 探讨外部环境资源(如就业资源和自然资源)短缺与否对员工选择时间和金钱奖励偏好的影响及内在机制。本文以即将步入职场的大学生和企业员工为样本, 发现不管是外在就业资源短缺还是外在自然资源短缺都会促使员工更加偏好金钱而非时间奖励, 内在机制是外部环境资源短缺时人们的心理表征更具体, 并且这一现象在高物质主义者身上更为明显(实验1和2)。本文结尾讨论了对资源短缺、时间和金钱等研究领域的理论突破与推进。

Abstract： Object detection is the basis of intelligent analysis, however, in the scene of illumination, shadow and clutter background, the problems of object misjudgment and unreasonable clustering is often appeared. Aiming at the above problems, propose a HVS-based object detection algorithm, which can optimize the error judgment and segmentation, and then accorded to the tracking characteristic of HVS and the continuity of object movement, combine the detection results of adjacent frames to achieve completely and accurately extraction object area. Finally, the simulation experiment based on the actual acquisition videos show that the proposed algorithm is more accurate and have good effect and in complex background.

Abstract： Objective To evaluate the efficacy and safety of long pulse 1064 nm Nd:YAG laser therapy in the treatment of onychomycosis of the toenails. Methods A total of 104 patients with onychomycosis (461 toenails) were divided by age into ≥60 years group and <60 years group, and each group was further divided into subgroups according to Scoring Clinical Index of Onychomycosis (SCIO) scoring and the location of the compromised toenails. All the toenails were treated with 10 to12 sessions of long pulse 1064 nm Nd:YAG laser therapy at the interval of 1 week. All the patients were followed up for 48 weeks after the initial treatment to assess the clinical efficacy and adverse reactions. Results The overall clinical response rate in these patients was 72.5% by the end of the 48-week follow-up. In patients aged <60 years, the clinical response rate and mycological cure rate were significantly higher than the rates in patients aged ≥60 years (P<0.05). No significant differences were observed in the response rates between different SCIO subgroups (P>0.05); the 2nd to 4th toenails showed better outcomes after the therapy than the 1st and 5th toenails (P<0.05). No adverse reactions related with the therapy were recorded in these patients. Conclusion Long pulse 1064 nm Nd:YAG laser is an effective and safe approach for treatment of onychomycosis of the toenails.
