Prescribed fire has now become the usual management practice in the Chinese fir （Cunninghamia lanceolata （Lamb.） Hook.） plantation in southern China. Heat generated during fire may affect carbon （C） dynam- ics in soils. We investigated the microbial biomass C （MBC） and microbial respiration in two Chinese fir forest soils （one is not exposed to fire for the past 88 years, and the other is recently exposed to prescribed fire） after soil heating （100 and 200 ℃） under three moisture regimes [25, 50 and 75 % of water holding capacity （WHC）]. For both soils, significant reduction in MBC with increasing heating temperature was found. Soils without exposing to fire previously had significantly greater MBC concentra- tion than the fire-exposed soils when heated at 100 or 200 ℃. Lower soil water content resulted in higher MBC concentrations in both soils. In contrast, both soils had the highest soil microbial respiration rate at 50 % WHC. Soils without exposing to fire previously had the greatest microbial respiration rates at 200 ℃, while the fire-ex- posed soils when heated at 100 ℃ had greatest microbialrespiration rates. During 14-days post-heat incubation, soil MBC in both soils was greatest after heating at 200 ℃ and 25 % WHC. However, soil previously exposed to fire had the lowest CO2 evolution when incubated at 25 % WHC.

BACKGROUND： It has been shown that irradiation to the neurolemma can reduce immuuogenicity. However, it is still poorly understood whether the degenerated nerve can affect peripheral nerve regeneration OBJECTIVE： To observe the effect of radiation-damaged nerve transplantation on functional recovery of the peripheral nerve. DESIGN, TIME AND SETTING： Self-control animal trial was performed at the Experimental Center of Orthopedics, Tangdu Hospital of Fourth Military Medical University from January to October 2005. MATERIALS： Fifty-four healthy, Chinese rabbits, irrespective of gender, were randomly divided into experimental （n = 36） and control （n = 18） groups. A 60 Co Y -radiation machine and NDI-200 nerve electromyograph were provided by the Experimental Center of Orthopedics, Tangdu Hospital of Fourth Military Medical University. METHODS： A median incision was made in the posterior right thigh of rabbits after abdominal anesthesia. A 30-mm segment of sciatic nerve was excised from the inferior margin of the piriform muscle to the tibiofibular intersection. The sciatic nerve in the experimental group was sterilely radiated with 350 Gy for 9.5 minutes. The damaged nerve segment was then re-transplanted. In the control group, the sciatic nerve was re-transplanted directly following excision. Nerve conduction velocity was determined at 4, 6, and 8 months post-surgery. MAIN OUTCOME MEASURES： Functional assessments, such as gait, nutritional status of skin on dorsum of foot, toe spreading reflex, and foot holding, were made between 1 and 180 days post-surgery. The common peroneal nerve and tibial nerve reflexes under clamping were observed at 4, 6, and 8 months post-surgery to evaluate functional restoration of the peripheral nerve. Electromyogram was performed to observe nerve conduction velocity. RESULTS： From postoperative days 1 to 26, the limbs that were transplanted with irradiated nerve exhibited dragged walking, foot drop, sole ulcers, depilation, self-induced i

For the patients with a relatively slow heart rate, the frequency of opening and closing of biological valves and the number ot impact ot mecnamcai stress upon biological valves were relatively less, so the mechanical wear was reduced. The question is whether this can slow the failure and calcification of the biological valve. A retrospective analysis replacement （MVR） cases was carried out. of 92 biological mitral valve during the period of 1996-2003

提出一种可用于视频中群体异常和个体异常检测的方法,即先用快速稀疏编码算法生成字典,再用字典表示测试特征样本,并以重构误差作为目标函数进行异常判别;对于群体异常,用块匹配运动估计代替耗时的整帧光流计算,生成多尺度运动直方图,有效地减少了计算复杂度;对于个体异常,提取HNF特征,若稀疏表达的重构误差超过阈值,则用惊奇计算进行二次检测,判断其是否为噪声导致的虚警,计算字典中已包含和未包含的不同特征描述子之间的差别,若判别出虚警,则更新字典减少后续检测中噪声干扰的虚警数.实验表明,算法有效地提高了检测率,降低了计算复杂度,且易于实现.

A novel architecture of motion estimation(ME) based on improved normalized partial distortion search is proposed to meet three primary requirements for real-time video encoding,which are low-power,lowbandwidth and high area utilization *** ME engine supports both normalized partial distortion search and adaptive search window *** former can reduce the computational complexity of ME to save power and area;the latter can avoid unnecessary accessing the external memory to lower the data *** proposed engine has been implemented with UMC 90nm CMOS *** implementation results show that,compared with traditional engines,the engine can achieve significant improvements of the hardware efficiency and the power efficiency respectively with a little throughput compromise.

林下植被是生态系统的重要组分。通过对比分析红壤侵蚀区植被恢复过程中,林下有无芒萁覆盖地的土壤可溶性有机碳(DOC,Dissolved Organic Carbon)含量及其与地下根系生物量、地上植被淋溶液DOC含量的关系。结果表明:林下植被芒萁覆盖增加了地上叶片和地下根系生物量,土壤DOC含量及储量也显著增加(P<0.05),芒萁覆盖对表层土壤(0—20cm)DOC的影响大于深层土壤(20—100cm)(P<0.05);相关分析结果表明,林下芒萁覆盖地土壤DOC储量与细根生物量的垂直变化呈显著的正相关关系(P<0.05),且随植被恢复年限的增加相关性显著增加,地下根系的垂直分布直接影响各土层DOC储量。不同植被恢复时期,林下芒萁覆盖地土壤DOC与鲜叶(马尾松+芒萁)和枯落物(马尾松+芒萁)淋溶液DOC均呈显著的正相关关系(P<0.01),而林下裸露地土壤DOC仅与鲜叶(马尾松)淋溶液DOC呈显著的相关性(P<0.01),林下芒萁覆盖地相对于裸露地枯落物淋溶液对土壤DOC储量的影响大于鲜叶。植被恢复过程中芒萁覆盖地土壤微生物生物量碳和微生物熵显著高于林下裸露地。因此,在植被恢复进程中,芒萁能够提供更多底物参与土壤物质与养分循环,对土壤DOC的贡献较大,为侵蚀区马尾松林恢复提供了重要的养分再吸收来源;同时芒萁覆盖增加了微生物活性,促进了微生物对土壤DOC的同化作用,提高了微生物碳源的利用率,对土壤有机碳的积累起着重要的作用。
