Real-time crash prediction on freeways using data mining and emerging techniques

Recent advances in intelligent transportation system allow traffic safety studies to extend from historic data-based analyses to real-time applications. The study presents a new method to predict crash likelihood with traffic data collected by discrete loop detectors as well as the web-crawl weather data. Matched case-control method and support vector machines （SVMs） technique were employed to identify the risk status. The adaptive synthetic over-sampling technique was applied to solve the imbalanced dataset issues. Random forest technique was applied to select the contributing factors and avoid the over-fitting issues. The results indicate that the SVMs classifier could successfully classify 76.32% of the crashes on the test dataset and 87.52% of the crashes on the overall dataset, which were relatively satisfactory compared with the results of the previous studies. Compared with the SVMs classifier without the data, the SVMs classifier with the web-crawl weather data increased the crash prediction accuracy by 1.32% and decreased the false alarm rate by 1.72%, showing the potential value of the massive web weather data. Mean impact value method was employed to evaluate the variable effects, and the results are identical with the results of most of previous studies. The emerging technique based on the discrete traffic data and web weather data proves to be more applicable on real- time safety management on freeways.

Investment in deepwater oil and gas exploration projects:a multi-factor analysis with a real options model

Deepwater oil and gas projects embody high risks from geology and engineering aspects, which exert substantial influence on project valuation. But the uncer- tainties may be converted to additional value to the projects in the case of flexible management. Given the flexibility of project management, this paper extends the classical real options model to a multi-factor model which contains oil price, geology, and engineering uncertainties. It then gives an application example of the new model to evaluate deepwater oil and gas projects with a numerical analytical method. Compared with other methods and models, this multi-factor real options model contains more project information. It reflects the potential value deriving not only from oil price variation but also from geology and engi- neering uncertainties, which provides more accurate and reliable valuation information for decision makers.

Discussion on Registration Validity Doctrine of Housing Land Use Right

Relationship between the registration and right change of housing land use right is not clearly stipulated in the Property Law. Land registration involves functions of private law and public law. It is partial to only considering private rights dimension when deciding whether registration validity doctrine or registration confrontation doctrine should be implemented in housing land use right. Compilation of land use planning, implementation of land use control and promotion of arrangement project in rural residential area all rely on sound and complete housing land registration data. To clarify housing land right adscription, eliminate hidden troubles causing housing land dispute and promote the establishment of harmonious countryside can never be achieved without housing land registration data. To carry out registration validity doctrine of housing land use right can effectively guide farmers' registration behavior and thus build a perfect registration information system of housing land use right. After the cross-village and even cross-town arrangement in rural residential areas, rural acquaintance society has transformed into semi-acquaintance society and even stranger society. Therefore, housing land use right commending its existence with registration in public form has been a necessary choice in legislation.

不动产物权期待权实体法外溢的反思与厘正--基于31份二手房“先卖后抵”判决书之整理

不动产物权期待权由民事执行法外溢至民事实体法,实体判决逻辑演绎的类型包括事实物权理论、优先顺位理论及权属争议理论。物权期待权实体权利化之外部源起在于民事执行程序的权利外溢及对域外法的期待权参引,内部因素包括解释论中物权期待权显现的制度优势、价值衡平理念下对生存权的保护以及对不动产登记制度的漏洞填补。赋予不动产买受人积极行使物权期待权的结果不仅遭受突破物权法定主义及公示公信原则、冲击债物二分财产体系之诘问,而且公示性及财产性能的缺失导致物权期待权存在固有缺陷。当程序法的独立价值使其具有独立规范执行阶段权利排序的功能时,具有公示性的预告登记制度的引入将高效填补实体法中物权期待权隐蔽优先性之缺憾。

Interferon-free treatments in patients with hepatitis C genotype 1-4 infections in a real-world setting

AIM To investigated the real-world effectiveness and safety of various regimens of interferon-free treatments in patients infected with hepatitis C virus(HCV).METHODS We performed an observational study to analyze different antiviral treatments administered to 462 HCV-infected patients, of which 56.7% had liver cirrhosis. HCV RNA after 4 wk of treatment and at 12 wk after treatment sustained virologic response(SVR) as well as serious adverse events(SAEs) was analyzed first for the whole cohort and then separately in patients who met or did not meet the inclusion criteria of a clinical trial(CT-met and CT-unmet, respectively).RESULTS The most frequently prescribed treatment was simeprevir/sofosbuvir(36.4%), followed by sofosbuvir/ledipasvir(24.9%) and ombitasvir/paritaprevir/ritonavir(r)/dasabuvir(19.9%). Ribavirin(RBV) was administered in 198 patients(42.9%). SVRs occurred in 437/462 patients(94.6%). The SVRs ranged between 93.3% and 100% for genotypes 1-4. SVRs were achieved in 96.2% patients in the CTmet group vs 91.9% patients in the CT-unmet group(P = 0.049). Undetectable HCV RNA at week 4 occurred in 72.9% of the patients. In the univariate analysis, the factors associated with SVRs were lower liver stiffness, absence of cirrhosis, higher platelet count, higher albumin levels, no RBV dose reduction, undetectable HCV RNA at week 4 and CT-met group. In the multivariate analysis, only albumin was an independent predictor of treatment failure(P = 0.04). Eleven patients(2.4%) developed SAEs; 5.2% and 0.7% of the patients in the CT-unmet and CT-met groups, respectively(P = 0.003).CONCLUSION A high proportion of patients with HCV infection achieved SVRs. For patients who did not meet the CT criteria, treatment regimens must be optimized.

无委托人的不动产信托的信托财产所有权转移登记

在我国应当将无委托人的不动产信托的受托人登记为作为其信托财产的不动产的所有权人;现存的关于这种不动产信托仍然以其委托人为前述不动产的登记所有权人的情形需要改变。要致使《中国信托法》能够为我国政府不动产登记机构办理前述登记提供民事实体法依据,需要将下述两项规定中的某一项增补入该法中:一项是以“无委托人的信托的信托财产权转归受托人享有”为其内容的规定,另一项是以“无委托人的信托的信托财产权置于受托人的名义之下”为其内容的规定。有可能在我国确立的只能够适用于这种不动产信托的不动产信托登记制度,应当考虑将与其适用对象相适应的下述两项规定纳入其中:第一项是记载不动产信托预先登记规则的规定,第二项是关于其适用能够将这种不动产信托的受托人置于由法律作为其信托财产的不动产设定的义务的承担者的地位的规定。

登记对抗主义下相对性物权说之批判

登记对抗主义物权变动规则由设立要件与对抗要件构成,其适用难点在于如何解释对抗要件所产生的登记对抗效力。相对性物权说在承认未登记物权仍为物权属性可对抗一般债权的前提下,主张未登记物权不能对抗特殊债权乃对抗要件发挥其登记对抗效力的必然结果,进而认为,在登记对抗主义下,依据合同设立的未登记物权具有相对性。然而,该学说偏离了物权界定规则与登记对抗规则的位阶关系,对域外法的借鉴未能作出契合本土的诠释,导致设立要件与对抗要件的功能错位。实质上,相对性物权说是以物权的相对性替换债权物权化。特殊债权优先受偿与登记对抗效力不存在必然联系,因而不应纳入登记对抗效力的调整范围。

不动产抵押登记被撤销后相关法律问题探究

已经登记的抵押权被撤销或注销后,抵押权是否有效以及各当事人之间如何承担责任的问题,在我国理论界探讨不足,立法上尚属空白。在司法实践中,由于不动产抵押登记行为具有行民交叉的特征,存在着诉讼路径与诉讼结果的冲突,增加了司法诉累,影响了司法公信力。抵押登记是一种行政行为,不是一种持续的状态。即使抵押权登记被撤销或被注销,抵押权人的信赖利益仍然受到法律的保护,抵押权应继续有效。应当采取抵押权登记纠纷的行民合并审理模式,以保护交易安全,节约司法成本。如果抵押登记在行政诉讼中被撤销或被行政机关主动注销,说明行政机关在当初登记时就有错误,受到损失的利害关系人可以要求登记机关承担赔偿责任。

物权登记错误行政赔偿裁判规则争议问题之再认识

需要受害人穷尽其他法律救济途径才能判令行政机关承担因登记错误致损赔偿责任的司法实践于法无据;物权登记错误行政赔偿与民事赔偿或者刑事附带民事赔偿等救济途径具有同等独立法律价值,人民法院应当根据当事人诉请依法裁判;司法实践和司法规范将以房屋登记为代表的物权登记行政赔偿归责原则确立为过错归责原则缺少法律依据。确立结果归责原则理据在于:具有法律规范依据,更加符合《国家赔偿法》《民法典》立法宗旨;与国家赔偿责任构成要件相匹配;结果归责原则并不要求物权登记机构承担绝对责任。将登记错误行政赔偿责任作为一种补充责任涉嫌违反《行政诉讼法》和《国家赔偿法》规定,也会造成新的不公平。根据物权交易民事侵权人与登记机构(工作人员)是否具有实施故意侵权意思联络为标准,登记错误行政赔偿责任可以分为份额责任和连带责任。

目的建立5-羟色胺2c受体（5-HTR2c）基因mRNA表达水平的TaqMan real—time PcR检测方法。方法以β-actin为内参基因，根据GenBank中人5-HTR2c及β-actin基因序列，分别设计了2套特异性引物和TaqMan探针，接着对反应的退火温度、引物浓度、探针浓度、Mg^2＋浓度进行优化，然后以优化的条件建立相对定量标准曲线，并对该方法的稳定性进行了分析。结果5-HTR2c及β-actin基因的real—time PCR扩增效率分别为99.9％和100.0％；相对定量标准曲线的CT值线性范围分别为12．2～35．1和11．5～31．5，相关系数分别为0．999及1．000；批内及批问变异系数（8．0％。结论本研究所建立的针对5-HTR2c mRNA表达水平的Taqman real-time PCR检测方法具有扩增效率高、稳定性好等特点，为进一步探索5-HTR2c的功能及其mRNA表达水平的变化和各种疾病发生、发展的相关性提供了有用的方法学基础。

“三权分置”背景下土地经营权登记的路径选择

农地“三权分置”背景下,土地经营权性质的界定关系到土地经营权的权利构造及其权利行使方式,对于后续改革与权利的完善具有重大意义。学界针对土地经营权登记问题的研究形成了债权和物权登记两种理论观点。就其权利属性而言,土地经营权债权登记欠缺理论基础且在实践中不具有可操作性,无法为权利人提供实质性保障。土地资源要素市场化的构建需要效力强大的物权为其提供制度支撑,土地经营权的物权属性为其纳入不动产登记体系提供了理论基础。物权登记路径的确立有着坚实的制度基础和法律保障,既符合农地改革的内在要求,也与我国正在建立实施的不动产统一登记制度相契合。

新时代背景下不动产登记制度改革发展成效及优化研究

我国不动产登记制度改革遵循着制度改革目标更加多元、发挥政策调整指引功能、制度建设更强调体系化、制度流程凸显出信息化、国家治理功能日益彰显的基本走向,历经多年改革发展,成效明显,体现为:逐步完善权责体系、逐步强化制度优势、逐步提升服务效能。但仍存在制度支撑不完善、部门协同不足、技术水平待提升等问题。据此,文章提出了完善不动产登记管理法律体系、推动相关部门之间的联动合作、建设不动产智慧化治理模式等具体路径。

基于二进制鲁棒不变尺度关键点-加速稳健特征的自然特征虚实注册方法

针对基于视觉的增强现实(AR)中虚实注册的准确率和实时效果受光照、遮挡和视角变化影响大,易导致注册失败的问题,提出一种基于二进制鲁棒不变尺度关键点-加速稳健特征(BRISK-SURF)算法的自然特征虚实注册方法。首先,利用加速稳健特征(SURF)特征提取算子检测特征点;然后,采用二进制尺度旋转不变鲁棒(BRISK)特征描述算子对特征点进行二进制描述,结合汉明距离实现准确高速的特征匹配;最后,根据图像间的单应性关系实现虚实注册。从图像特征匹配和虚实注册两方面进行实验,结果显示BRISK-SURF算法的平均准确率与SURF算法基本保持一致,比BRISK算法提高了约25%,平均召回率提高了约10%;基于BRISK-SURF的注册方法的结果接近参考标准数据,精度较高,实时性较好。实验结果表明,所提方法对于光照、遮挡和视角情况不同的图像具有较高的识别准确度、注册精度和实时效果。另外,使用此方法实现了基于AR的交互式旅游资源呈现与体验系统。
