Multiple myeloma （MM） is a uniformly fatal disease characterized by a clonal proliferation of neoplastic plasma cells in the bone marrow and is the second most commol hematological malignancy.1 At present, a cure for multiple myeloma has not been achieved with chemotherapeutic regimen, and many patients die of drug-resistant disease. Thus, the development of new effective anticancer agents to treat both early and advanced MM seems to be an attractive perspective.

集料级配是影响沥青路面抗滑和减噪性能的最主要因素,基于机器视觉技术,提出一种集料粒径高精度无损检测方法,结合骨架提取和支持向量机(SVM)算法来实现集料颗粒粒度分布的精确估计,为保证集料级配质量提供了有效手段。集料颗粒图像由数字相机获取,图像标定基于NI视觉助手Vision Assistant软件完成。颗粒骨架图像采用Skeleton-M骨架提取算法提取,针对所出现的骨架断裂情况,使用形态学膨胀和细化算法完成骨架修复;然后基于颗粒骨架图像提出颗粒粒径表征算法,基于骨架端点个数提出颗粒棱角表征方法;最后,通过提取颗粒图像特征参数,使用SVM算法对颗粒粒径分布进行精确估计。在颗粒棱角性表征方面,将所提出的颗粒骨架棱角性表征法与AIMS系统的梯度棱角法、未压实空隙率集料颗粒棱角法进行了比较。结果表明:与目前常见的粒径表征方法相比,所提出的方法可以较好地实现颗粒粒径表征和颗粒棱角性表征,所采用的基于多特征的SVM颗粒分档算法可以有效实现颗粒粒径分档,筛分档间的分档精度最高可达95%以上。

An exceptional rainy season occurred in the Yangtze River valley of eastern China in June-July *** relative importance of the dynamic and thermodynamic effects on this unusual event is evaluated through the budget equations of moisture and moist static energy(MSE).The moisture budget analysis suggests that the thermodynamic effect contributes to the precipitation anomaly by 8.5%through the advection of abnormal water vapor by mean vertical motion,while the dynamic effect,related to water vapor advection by anomalous vertical motion,has the dominant *** MSE budget analysis further reveals that the anomalous vertical motion is both constrained by the dynamic effect related to changes in atmospheric circulation and the thermodynamic effect related to changes of the atmospheric thermal state,with a ratio of thermodynamic versus total effects estimated at 45.3%.The dynamic effect is linked to the advection of warm and humid air by the abnormal southwesterly wind,which is related with an anomalous anticyclone over the Philippine *** thermodynamic effect is partly induced by the positive advection of anomalous MSE(mainly latent energy)by the mean vertical *** analysis of the dynamic and thermodynamic effects is useful to understand the underlying physical mechanisms leading to the unusual rainy season in the Yangtze River valley in summer *** is also helpful to put forward a few speculations on the potential role of global warming whose primary effect is,after all,to change the thermal state of the atmosphere.

Let L =-△+V(x) be a Schrodinger operator, where △ is the Laplacian on R^n,while nonnegative potential V(x) belonging to the reverse Holder class. The aim of this paper is to give generalized weighted Morrey estimates for the boundedness of Marcinkiewicz integrals with rough kernel associated with Schrodinger operator and their ***, the boundedness of the commutator operators formed by BMO functions and Marcinkiewicz integrals with rough kernel associated with Schrodinger operators is discussed on the generalized weighted Morrey spaces. As its special cases, the corresponding results of Marcinkiewicz integrals with rough kernel associated with Schrodinger operator and their commutators have been deduced, respectively. Also, Marcinkiewicz integral operators, rough Hardy-Littlewood(H-L for short) maximal operators, Bochner-Riesz means and parametric Marcinkiewicz integral operators which satisfy the conditions of our main results can be considered as some examples.

This study investigated the calcareous nannofossil assemblages in detail from the early Miocene aged Lice Formation outcropping in the Kahramanmara? basin. The biostratigraphy of calcareous nannofossils was outlined and paleoenvironmental features determined. In 81 samples taken from three measured sections in the region, 17 calcareous nannofossil genus and 48 nannofossil species were identified. These calcareous nannofossil genus and species identified the Lice Formation as being in the CNM4 nannofossil biozone. The abundance and diversity of early Miocene calcareous nannofossil species varied in the measured sections, with the samples generally moderate-poor, apart from a few samples. The relative abundance of individuals of Cyclicargolithus floridanus, Coccolithus pelagicus, Reticulofenestra hagii and Sphenolithus moriformis species, with paleoecological importance identified in the study region, indicate that in early Miocene times, the basin in which the Lice Formation deposited was meso-eutrophic with excess nutrient input, temperate and generally stable shallow marine conditions.
