Given a road network G = （V, E）, where V（E） denotes the set of vertices（edges） in G, a set of points of interest P and a query point q residing in G, the reverse furthest neighbors （RFNR） query in road networks fetches a set of points p ∈ P that take q as their furthest neighbor compared with all points in P ∪ {q}. This is the monochromatic RFNR （MRFNR） query. Another interesting version of RFNR query is the bichromatic reverse furthest neighbor （BRFNR） query. Given two sets of points P and Q, and a query point q ∈ Q, a BRFNR query fetches a set of points p ∈ P that take q as their furthest neighbor compared with all points in Q. This paper presents efficient algorithms for both MRFNR and BRFNR queries, which utilize landmarks and partitioning-based techniques. Experiments on real datasets confirm the efficiency and scalability of proposed algorithms.

To the Editor:Angiosarcoma(AS)is a rare and highly malignant mesenchymal tumor that accounts for 2%of adult soft tissue *** prognosis of AS is poor due to the high rate of metastasis and *** to a retrospective study by Lahat et al and Fayette et al,[1,2]31 of 121(19%)patients had metastases upon initial diagnosis,and 90(74%)had relapse and *** median survival of AS was 3.4 years,declining to 10 months in patients with *** attempt to improve AS treatment outcomes,a multimodality approach is advocated,including surgical resection combined with radiation,chemotherapy,immunotherapy,and/or anti-angiogenetic ***,we present a man who previously underwent resection of a mesorectal-derived intermediate hemangioendothelioma(HAE)and developed pulmonary metastasis of AS within a *** history is remarkable because of(1)the rare primary location:only 2 cases were mesenteric-related;(2)the uncharacteristic clinical course:the primary diagnosis of intermediate hemangioendothelioma later progressed to pulmonary metastatic AS;and(3)a successful series of multidisciplinary therapeutic procedures,especially selective arterial infusion(SAI)chemotherapy before metastases resection.

Although solar steam generation strategy is efficient in desalinating seawater,it is still challenging to achieve continuous solar-thermal desalination of seawater and catalytic degradation of organic ***,dynamic regulations of hydrogen bonding networks and solvation structures are realized by designing an asymmetric bilayer membrane consisting of a bacterial cellulose/carbon nanotube/Co_(2)(OH)_(2)CO_(3)nanorod top layer and a bacterial cellulose/Co_(2)(OH)_(2)CO_(3)nanorod(BCH)bottom ***,the hydrogen bonding networks inside the membrane can be tuned by the rich surface–OH groups of the bacterial cellulose and Co_(2)(OH)_(2)CO_(3)as well as the ions and radicals in situ generated during the catalysis ***,both SO_(4)^(2−)and HSO_(5)−can regulate the solvation structure of Na^(+)and be adsorbed more preferentially on the evaporation surface than Cl^(−),thus hindering the de-solvation of the solvated Na^(+)and subsequent nucleation/growth of ***,the heat generated by the solar-thermal energy conversion can accelerate the reaction kinetics and enhance the catalytic degradation *** work provides a flow-bed water purification system with an asymmetric solar-thermal and catalytic membrane for synergistic solar thermal desalination of seawater/brine and catalytic degradation of organic pollutants.

AIM To further investigate the effect of cyclin D1 on the biologic behavior of cancer cells and its potential role in gene therapy of tumor. METHODS A cyclin D1 subcloning plasmid termed BKSD1 was constructed by subcloning the human cyclin D1 cDNA into Bluescript KS, a plasmid vector with a pair of T7 and T3 promoters, with recombinant DNA technology of molecular biology. So, it is easy to generate digoxigenin (DIG) labeled RNA probes of antisense and sense to cyclin D1 using RKSD1 as a template vector. PDORD1AS, an eukaryotic expression vector containing the full length human cyclin D1 cDNA in its antisense orientation cloned into the retroviral vector pDOR neo, was successfully constructed with BKSD1 to change restriction sites. A gastric cancer cell line, SGC7901/VCR, was transfected with pDORD1AS by Lipofect Amine mediated introduction and a subline termed SGC7901/VCRD1AS, which had stable overexpression of antisense RNA to cyclin D1, was obtained by selection in G418. The subline, control subline transfected pDOR neo and SGC7901/VCR were evaluated by methods of immunohistochemistry, flow cytometry, molecular hybridization, morphology and cell biology. RESULTS Compared with control cell lines, SGC7901/VCRD1AS had a reduced expression of cyclin D1 (inhibition rate was about 36%), increased cell size and cytoplasm to nucleus ratio, increased doubling time (42 2h to 26 8h and 26 4h), decreased saturation density (18 9×10 4 to 4 8×10 5 and 4 8×10 5), increased percentage of cells in the G1/G0 phase (80 9%-64 6% and 63 8%), reacquired serum dependence, and a loss of tumorigenicity in nude mice (0/4 to 4/4 and 4/4). CONCLUSION Stable overexpression of antisense RNA to cyclin D1 can reverse the transformed phenotype of human gastric cancer cells and may provide an approach of gene therapy for gastric cancer.

采用激光粒度分析仪对乙醇/柴油混合燃料稳态自由喷雾粒度分布进行了试验研究,并就不同喷油压力、喷孔直径对乙醇、柴油及乙醇/柴油混合燃料稳态自由喷雾粒度分布的影响进行了对比研究。试验结果表明:各种燃料喷雾索特平均直径(SMD)的空间分布沿喷雾轴线均呈逐渐减小的趋势,其中柴油喷雾的SMD在20～40μm范围内变化,乙醇喷雾较柴油喷雾具有更小的SMD,且其空间分布较为均匀;随着乙醇含量的增加,乙醇/柴油混合燃料喷雾的SMD不断减小,其SMD大小和空间分布均匀性介于柴油喷雾和乙醇喷雾之间。

在压力定容室内,利用数字粒子图像速度场仪(DPIV)对二甲醚(DME)闪急沸腾喷雾特性,以及DME和柴油的常规喷雾特性开展了试验研究;建立了适用于DME闪急沸腾喷雾的宏观现象学模型,并将该模型与KIVA程序相耦合,藉此对DME闪急沸腾喷雾特性进行了数值模拟。研究结果表明:与柴油常规喷雾相比,DME闪急沸腾喷雾贯穿距较短,但喷雾锥角较大;喷雾初始段的计算值与试验测量值吻合较好,但喷雾后期的吻合程度稍差。计算研究表明:DME闪急沸腾喷雾体前端两侧存在着明显的涡环结构,喷雾场中DME的气相浓度大幅度高于柴油喷雾的气相浓度,且其索特平均直径(SMD)比柴油小得多。
