Cq-commuting maps and invariant approximations  [cached]
N. Hussain,B. E. Rhoades
Fixed Point Theory and Applications , 2006, DOI: 10.1155/fpta/2006/24543
Abstract: We obtain common fixed point results for generalized I-nonexpansive Cq-commuting maps. As applications, various best approximation results for this class of maps are derived in the setup of certain metrizable topological vector spaces.

Abstract: 目的研究不稳定逼尿肌中ICCs细胞的数量、分布形式的变化及其功能改变对逼尿肌肌条收缩的影响,初步探讨ICCs细胞与逼尿肌不稳定的关系。方法近端尿道结扎法建立大鼠不稳定膀胱模型。分别于正常及不稳定膀胱的相同部位剪取3mm×4mm逼尿肌组织进行免疫荧光组织化学法检测c?kit阳性细胞的表达及分布情况;再于相同部位剪取2mm×7mm肌条进行收缩特性测定实验,并检测c-kit受体阻断剂对收缩的影响。结果不稳定逼尿肌中c-kit阳性细胞的数量较正常逼尿肌明显增多(P<0.05);正常逼尿肌中c-kit阳性细胞以散在分布为主,不稳定逼尿肌中以细胞网络形式存在;不稳定逼尿肌肌条的收缩频率和收缩幅度显著高于正常膀胱(P<0.05);加入Glevic后,不稳定逼尿肌肌条的收缩幅度显著减弱(P<0.05),频率无显著差异(P>0.05)。结论不稳定膀胱中ICCs细胞的数量明显增加,主要以细胞网络的形式存在;不稳定逼尿肌肌条收缩幅度和频率明显增高,但其收缩幅度可以被Glevic削弱,提示ICCs与逼尿肌不稳定的发生有密切关系。

Physics , 2013, DOI: 10.1063/1.4883879
Abstract: We show that multipartite mixed bipartite CC and CQ states are geometrically and topologically distinguished in the space of states. They are characterized by non-vanishing Euler-Poincar\'{e} characteristics on the topological side and by the existence of symplectic structure on the geometric side.
二迭纪  [PDF]

地质与勘探 , 1980,
Abstract: 二迭纪(Permian)的名字来自俄罗斯北部贝尔姆省的名称,因为那里的二迭纪地层特别发育.其两分的由来是因为德国这个纪的地层明显地分为上下两部分而得名.世界二迭系(1841年莫迪逊确立了二迭系.1900年巴黎国际地质会议尚未承认二迭系,现在一般都承认了)标准剖面最初建立在西乌拉尔贝尔姆〔狭义的萨克马尔组(Sakmarian)〕,后在美国得克萨斯又建立一条剖面.这两条标准剖面的上部均为含盐建造,化石稀少,远没有我国二迭系剖面完整、
Large grains in the disk of CQ Tau  [PDF]

Abstract: We present 7mm observations of the dusty disk surrounding the 10 Myr old 1.5 Msun pre-main-sequence star CQ Tauri obtained at the Very Large Array with 0.8 arcsecond resolution and 0.1 mJy rms sensitivity. These observations resolve the 7mm emission in approximately the north-south direction, confirming previous results obtained with lower resolution. We use a two-layer flared disk model to interpret the observed fluxes from 7mm to 1.3mm together with the resolved 7mm structure. We find that the disk radius is constrained to the range 100 to 300 AU, depending on the steepness of the disk surface density distribution. The power law index of the dust opacity coefficient, beta, is constrained to be 0.5 to 0.7. Since the models indicate that the disk is optically thin at millimeter wavelengths for radii greater than 8 AU, the contribution of an optically thick region to the emission is less than 10%. This implies that high optical depth or complex disk geometry cannot be the cause of the observed shallow millimeter spectral index. Instead, the new analysis supports the earlier suggestion that dust particles in the disk have grown to sizes as large as a few centimeters. The dust in the CQ Tauri system appears to be evolved much like that in the TW Hydra system, a well-studied pre-main-sequence star of similar age and lower mass. The survival of gas-rich disks with incomplete grain evolution at such old ages deserves further investigations.

Abstract: 目的观察膀胱出口部分梗阻(partialbladderoutletobstruction,PBOO)不同阶段逼尿肌收缩力及神经纤维密度的改变,探讨PBOO对逼尿肌收缩力的影响及其与神经支配的关系。方法近端尿道结扎法建立大鼠PBOO模型,实验动物分为4组:假手术6周组及8周组、梗阻6周组及8周组。通过测定膀胱排尿压及顺应性以及离体逼尿肌条收缩幅度评估逼尿肌收缩力;应用神经递质乙酰胆碱M受体阻滞剂阿托品以及激动剂卡巴可观察其对逼尿肌收缩的影响;采用免疫荧光组化法检测逼尿肌神经纤维表达。结果梗阻6周组膀胱排尿压[(25.7±2.3)cmH2O]及顺应性[(0.24±0.03)mL/cmH2O]较假手术组排尿压[(18.7±1.6)cmH2O]及顺应性[(0.15±0.02)mL/cmH2O]显著增高(P<0.01);梗阻8周组膀胱排尿压[(10.8±1.7)cmH?2O]及顺应性[(0.11±0.02)mL/cmH2O]较假手术组膀胱排尿压[(19.2±2.1)cmH2O]及顺应性[(0.17±0.02)mL/cmH2O]显著降低(P<0.01)。梗阻6周组逼尿肌条收缩幅度较假手术组显著增高[(0.31±0.03)gvs(0.15±0.02)g,P<0.01],加入阿托品后逼尿肌条收缩幅度明显降低(P<0.05),但仍较假手术组高(P<0.01);梗阻8周组逼尿肌条收缩幅度较假手术组显著降低[(0.09±0.01)gvs(0.16±0.02)g,P<0.01],加入卡巴可后无明显改善(P>0.05)。梗阻组逼尿肌中神经纤维密度随梗阻时间延长明显降低(P<0.05)。结论持续膀胱出口部分梗阻可以导致逼尿肌收缩力呈双向性改变,神经支配在此过程中影响有限,可能主要源于自身肌源性因素改变。

Abstract: ????????目前对南海崖城13-1气田储层非均质性的认识还不清楚,气田储量动用程度较低,动态、静态地质储量差异较大。因此,利用岩心、测井和地震等资料对崖城13-1气田的主力生产层位进行沉积微相和储层特征开展综合研究尤为重要。崖城13\|1气田勘探目的层段为古近系渐新统陵三段,主要形成于海陆过渡环境,发育辫状河三角洲,沉积亚相主要为上三角洲平原、下三角洲平原、三角洲内前缘和三角洲外前缘。储集砂体主要为中—粗砂岩和含砾粗砂岩,其沉积微相为水下分流河道、河口坝和远砂坝。储层物性较好,孔隙度大于10%。储层物性主要受控于压实作用、溶蚀作用和沉积微相。
“倒逼”还是“反倒逼”——农村税费改革前后中央与地方之间的互动  [PDF]

Abstract: 为了解决农民负担问题所引致的治理性危机,中央政府试图通过农村税费改革来倒逼基层政府对自身进行改革。由于税费改革是自上而下推动的,农村基层政府为了维护自身的利益,作为行政层级最末端的行为体,惟有被动地以“弱者的手段”回应上级压力,其客观结果却是农村公共产品阙如、基层政府运作困难,农村出现新一轮治理危机,由此形成向上的反倒逼现象,以致中央和省级政府只有采取新的措施,投放更多资源来解决农村问题。本文认为,朝着这个新趋向发展,将有助于进一步改进农村社会的治理。
