For automatic object detection tasks,large amounts of training images are usually labeled to achieve more reliable training of the object classifiers;this is cost-expensive since it requires hiring professionals to label large-scale training *** a large number of object classes come into view,the issue of obtaining a large enough amount of the labeled training images becomes more *** are three potential solutions to reduce the burden for image labeling:(1) allowing people to provide the object labels loosely at the image level rather than at the object level(e.g.,loosely-tagged images without identifying the exact object locations in the images) ;(2) harnessing large-scale collaboratively-tagged images that are available on the Internet;and,(3) developing new machine learning algorithms that can directly leverage large-scale collaboratively-or loosely-tagged images for achieving more eective training of a large number of object *** on these observations,a multi-task multi-label multiple instance learning(MTML-MIL) algorithm is developed in this paper by leveraging both inter-object correlations and large-scale loosely-labeled images for object classifier *** seamlessly integrating multi-task learning,multi-label learning,and multiple instance learning,our MTML-MIL algorithm can achieve more accurate training of a large number of inter-related object classifiers(where an object network is constructed for determining the inter-related learning tasks directly in the feature space rather than in the label space) .Our experimental results have shown that our MTML-MIL algorithm can achieve higher detection accuracy rates for automatic object detection.

Resonating-group method has been applied to calculate the ΩΩ (SIJ = -6,0,0) dibaryon state in theframework of the extended quark-delocalization color-screening model. The mass of the di-Ω is predicted to be about45 MeV lower than the Ω-Ω threshold. The effect of channel coupling due to the tensor force and sensitivity to mesonexchange short-range cutoff radius, ro have also been studied.

Tank sloshing in ship cargo is excited by ship motions, which induces impact load on tank wall and then affects the ship motion. Wave forces acting on ship hull and the retardation function are solved by using three-dimensional frequency domain theory and an impulse response function method based on the potential flow theory, and global ship motion is examined coupling with nonlinear tank sloshing which is simulated by viscous flow theory. Based on the open source Computational Fluid Dynamics （CFD） development platform Open Field Operation and Manipulation （OpenFOAM）, numerical calculation of ship motion coupled with tank sloshing is achieved and the corresponding numerical simulation and validation are carried out. With this method, the interactions of wave, ship body and tank sloshing are completely taken into consideration. This method has quite high efficiency for it takes advantage of potential flow theory for outer flow field and viscous flow theory for inside tank sloshing respectively. The numerical and experimental results of the ship motion agree well with each other.

The characteristics of diagenetic minerals and their effects on reservoir quality of the tight sandstones of the Permian in Sulige gas field of the Ordos Basin were studied through observations on thin sections,scanning electron microscopy,energy dispersive spectroscopy analysis and electron microprobe *** minerals in the Permian sandstones consist of illite,kaolinite,chlorite,siliceous and calcite *** amounts of intercrystalline pores between kaolinite and illite provide channels for acidic fluids flow and thereby were conducive to the formation of clastic solution pores,intergranular solution pores and composite *** chlorite occurs in the form of three morphotypes as grain-coating,pore-lining and ***-coating and pore-lining chlorite with different crystal shapes occur as coatings on the framework ***-filling chlorite precipitated as discrete flaky plates in pore *** microcrystals developed but quartz overgrowth did not develop because of the occurrence of porelining ***,in turn,led to the preservation of primary pores by occupying potential nucleation sites for quartz overgrowth and thereby preventing quartz microcrystals from merging into quartz *** process is regarded as the most important for influencing the quality of the lithophysical *** cement was mainly precipitated during a late diagenetic stage and has a negative effect on the reservoir *** study provides important insights into analyzing the relationship between diagenetic minerals and reservoir quality and the results are directly applicable to the exploration and development of tight sandstone reservoirs all over the world.
