In order to explore the interaction be- tween the sea and monsoon in the South China Sea, the heat exchanges at air-sea interface during mon- soon periods in 1986 were calculated using observa- tional data. It shows that when the summer monsoon bursts and prevails over the South China Sea, the air-sea interface heat exchange is strong and the latent heat rises rapidly in the intertropical conver- gence zone and the tropic cyclone system near 20.49°N, 114.14°E. On May 24, 1986, the sensible heat became positive in the typhoon system. The heating exchange indicates that heat is transported from ocean to atmosphere, with major contribution of latent heat. When the summer monsoon prevails over the South China Sea and the weather is fine, even SST (sea surface temperature) is high, but sensible heat appears to be negative. The heat exchange indicates that heat is transported from atmosphere to ocean, with major contribution of short-wave radiation absorbed by sea surface and sensible heat. When summer monsoon is over and the northeast monsoon prevails over the South China Sea, the heat ex- change at air-sea interface is very strong. The heat- ing exchange shows that the ocean heats the at- mosphere, with major contribution of latent heat when cold air arrives at the sea surface and the sensible heat rises to positive rapidly. Therefore it can be concluded that the heat exchange at air-sea interface is different from the SST in South China Sea. Whenthe summer monsoon prevails over the South China Sea, the main trend is the ocean responding to the atmosphere.

The rapid growth of multimedia content necessitates powerful technologies to filter, classify, index and retrieve video documents more efficiently. However, the essential bottleneck of image and video analysis is the problem of semantic gap that low level features extracted by computers always fail to coincide with high-level concepts interpreted by humans. In this paper, we present a generic scheme for the detection video semantic concepts based on multiple visual features machine learning. Various global and local low-level visual features are systelrtically investigated, and kernelbased learning method equips the concept detection system to explore the potential of these features. Then we combine the different features and sub-systen on both classifier-level and kernel-level fusion that contribute to a more robust system Our proposed system is tested on the TRECVID dataset. The resulted Mean Average Precision （MAP） score is rmch better than the benchmark perforrmnce, which proves that our concepts detection engine develops a generic model and perforrrs well on both object and scene type concepts.

MicroRNAs （miRNAs） that exert function by posttran- scriptional suppression have recently brought insight in our understanding of the role of ***-coding RNAs in carcinogenesis and metastasis. In this study, we described the function and molecular mechanism of miR-139-5p in colorectal cancer （CRC） and its potential clinical application in CRC. We found that miR-139-5p was significantly downregulated in 73.8% CRC samples compared with adjacent noncancerous tissues （NCTs）, and decreased miR-139-5p was associated with poor prognosis. Functional analyses demonstrated that ectopic expression of miR-139-5p suppressed CRC cell migration and invasion in vitro and metastasis in vivo. Mechanistic investigations revealed that miR-139-5p suppress CRC cell invasion and metastasis by targeting AMFR and NOTCH1. Knockdown of the two genes phe- nocopied the inhibitory effect of miR-139-5p on CRC metastasis. Furthermore, the protein levels of the two genes were upregulated in CRC samples compared with NCTs, and inversely correlated with the miR-139-5p expression. Increased NOTCH1 protein expression was correlated with poor prognosis of CRC patients. Together, our data indicate that miR-139-5p is a potentialtumor suppressor and prognostic factor for CRC, and targeting miR-139-5p may repress the metastasis of CRC and improve survival.

Enhancer of zeste homolog 2(EZH2),an epigenetic regulator that inhibits transcription primarily through trimethylation of Lys-27 in histone 3(H3K27me3),has been reported to play an important role in the regulation of cell cycle,autophagy,and apoptosis,and DNA damage repair.1 EZH2 is highly expressed in a variety of cancers including prostate cancer,breast cancer,and renal clear cell carcinoma,and is associated with adverse prognosis.1 Moreover,it has been reported that EZH2 might increase tumor stemness and metastasis capacity and inhibit antitumor immunity by affecting T cells,NK cells,macrophages,and immune checkpoints.2,3 However,the prognostic value and the mechanism of EZH2 have not been investigated in *** this study,RNA sequencing and whole genome sequencing data based on 48 skull base chordomas as well as immunohistochemistry of paraffin sections were analyzed to elucidate the role of EZH2 in skull base *** found copy number gain mediated high EZH2 expression is associated with tumor stemness,M2 macrophage infiltration,and adverse prognosis in ***,we demonstrated that EZH2 promotes the proliferation,migration,and invasion of chordoma cells in in vitro cell experiments.

Osa-miR439 is a rice-specific microRNA family. Here we showed that Osa-miR439 acted as anegative regulator in rice immunity against blast fungus Magnaporthe oryzae. Osa-miR439 differentiallyresponded to M. oryzae between susceptible and resistant rice accessions. The accumulation ofOsa-miR439 was constitutively more in the susceptible accession than in the resistant one. Transgeniclines overexpressing Osa-miR439a (OX439a) showed higher susceptibility associating with lower inductionof defense-related genes and less hydrogen peroxide (H2O2) accumulation at the infection sites than thecontrol plants. In contrast, transgenic lines expressing a target mimic of Osa-miR439 (MIM439) displayedcompromised susceptibility associating with increased H2O2 accumulation. Furthermore, we found thatthe expression of three predicted target genes was decreased in OX439a but increased in MIM439 incomparison to control plants, and this expression was differential in susceptible and resistant accessionsupon M. oryzae infection, indicating that Osa-miR439a may regulate rice blast resistance via these *** results unveiled the role of Osa-miR439a in rice blast resistance and provided the potentiality toimprove the blast resistance via miRNA.
