We study the spin precession frequency of a test gyroscope attached to a stationary observer in the five-dimensional rotating Kaluza-Klein black hole(RKKBH). We derive the conditions under which the test gyroscope moves along a timelike trajectory in this geometry, and the regions where the spin precession frequency diverges. The magnitude of the gyroscope precession frequency around the KK black hole diverges at two spatial locations outside the event horizon. However, in the static case, the behavior of the Lense-Thirring frequency of a gyroscope around the KK black hole is similar to the ordinary Schwarzschild black hole. Since a rotating Kaluza-Klein black hole is a generalization of the Kerr-Newman black hole, we present two mass-independent schemes to distinguish these two spacetimes.

Rooftop gardening or green roof establishment, one of the methods of afforestation for urban greening, has many benefits for the environment, the economy and urban landscapes. Various environmental stresses including heat, strong wind, sunshine and cold prevent most plants from growing well in extensive green roof systems. For the establishment of urban rooftop gardening in Beijing, we evaluated 13 ornamental plant species [Berberis thunbergii ‘Atropurea Nana’, Euonymus fortune （Turcz.） Hand., Viburnum dilatatum Thunb., Cotinus coggygria Scop., Swida alba Opiz., Weigela florida （Bunge.） A. DC., Jasminum nudiflorum lindl., Euonymus japonicus Thunb., Euonymus japonicus ‘Cuzhi’, Buddleja davidii Franch., Pyracantha fortuneana （Maxim.） Li., Ligustrum lucidum Ait. and Spiraea salicifolia L.] for greening of flat rooftops. We obtained three indices concerning cold resistance, i.e., electrical conductivity of leaves, amounts of soluble sugars and amounts of free proline, providing a theoretical basis for selection of plants fit for roof and balcony greening. The results show that the six species P. fortuneana （Maxim.） Li., B. thunbergii ‘Atropurea Nana’, J. nudiflorum lindl., E. fortune （Turcz.） Hand., E. japonicus Thunb. and E. japonicus ‘Cuzhi’ are excellent plants for rooftop gardening, judging from their strong ability in cold resistance. Plants such as L. lucidum Ait., C. coggygria Scop. and W. florida （Bunge） A. DC. showed a medium ability in cold resistance. However, these species can be used in roof and balcony greening after intensive management or acclimatization of variety. The ability to resist cold of plants such as W. florida （Bunge） A. DC., S. salicifolia L., V. rhytidophyllum and S. alba Opiz. （Cornus alba L.） was found to be rather weak. Therefore, cold-proof measures are recommended when using these species.

作者： Xian-kai lin Rui Wang Fan Zeng 李书宏徐彩虹 School of Science Beijing Technology andBusiness UniversityBeijing 100048China Institute of Chemistry Chinese'Academy of SciencesBeijing 100190China

New silicon-containing phenyleneethynylene hybrid oligomers P2, P3, and P4 were synthesized via Sonogashira cross-coupling reactions of ethynyl-terminated silazane monomer N,N′-bis（4-ethynylphenyl）-1,1-diphenylsilazane（M1） and corresponding bis-（4-bromo-phenyl）-ended organosilicon unit containing monomers, respectively. These new oligomers were easily soluble in common solvents. The incorporation of flexible organosilicon units in the oligomers leads to blue-shift in both the UV-Vis absorption and fluorescence emission spectra similarly. The results of differential scanning calorimetry（DSC） indicate that the flexible units relieve the rigidity of oligomeric chain and provide favorable conformation for thermal cross-linking reactions. The oligomers show good thermal and thermal-oxidative stability from the thermogravimetric analysis（TGA）, with their decomposition temperature at 10% weight loss（T10%） higher than 400 ？C under both nitrogen and air atmosphere.

非酒精性脂肪性肝病(non-alcoholic fatty liver disease,NAFLD)是全国范围内普遍发病的慢性非传染性肝脏疾病,也是肝硬化肝癌的前期阶段,严重威胁着人类健康。高原低氧条件下机体各器官系统受到不同程度影响,而肝脏组织缺氧程度进一步加重,呈现出高原地区NAFLD的患病率显著高于平原地区。目前NAFLD发病机制观点不一,而且高原低氧促进NAFLD进展机制尚不明确。本文从高原低氧对肝实质细胞和间充质细胞的影响角度入手,整合、梳理相关研究报道,并探索高原低氧在NAFLD慢性病进展中发生、发展的可能机制,为NAFLD的预防、诊治提供新思路。

This article investigates the performance of hybrid automatic repeat request （HARQ） with code combining over the ideally interleaved Nakagami-m fading channel. Two retransmission protocols with coherent equal gain code combining are adopted, where the entire frame and several selected portions of the frame are repeated in protocols I and II, respectively. Protocol II could be viewed as a generalization of the recently proposed reliability-based HARQ. To facilitate performance analysis, an approximation of the product of two independent Nakagami-m distributed random variables is first developed. Then the approximate analysis is utilized to obtain exact frame error probability （FEP） for protocol I, and the upper bound of the FEP for protocol II. Furthermore, the throughput performance of both two protocols is presented. Simulation results show the reliability of the theoretical analysis, where protocol II outperforms protocol I in the throughput performance due to the reduced amount of transmitted information.

Hypoxia is a common phenomenon in hepatocellular carcinoma （HCC）. Hypoxia stabilizes transcription factor, hypoxia-inducible factor （HIF）, to activate gene transcription. Expression of HIF is closely associated with metastasis and poor prognosis in HCC. HIF mediates expression of genes that are involved in every step of HCC metastasis including epithelial-mesenchymal transition, invasion of the extracellular matrix, intravasation, extravasation, and secondary growth of the metastases. Because HIF is the central regulator of HCC metastasis, HIF inhibitors are attractive tools when used alone or as combined treatment to curb HCC metastasis. This review will summarize the current findings on the impact of hypoxia/HIF in HCC, with a particular focus on cancer metastasis.
