NuMDG:A New Tool for Multiway Decision Graphs Construction

引用

Journal of Computer Science & Technology 2011年第1期26卷 139-152页

作者： Sa'ed Abed Yassine Mokhtari Otmane Ait-Mohamed sofiene Tahar Department of Computer Engineering Hashemite UniversityZarqaJordan Department of Electrical and Computer Engineering Concordia UniversityMontrealCanada

Multiway Decision Graphs （MDGs） are a canonical representation of a subset of many-sorted first-order logic. This subset generalizes the logic of equality with abstract types and uninterpreted function symbols. The distinction between abstract and concrete sorts mirrors the hardware distinction between data path and control. Here we consider ways to improve MDGs construction. Efficiency is achieved through the use of the Generalized-If-Then-Else （GITE） commonly operator in Binary Decision Diagram packages. Consequently, we review the main algorithms used for MDGs verification techniques. In particular, Relational Product and Pruning by Subsumption are algorithms defined uniformly through this single CITE operator which will lead to a more efficient implementation. Moreover, we provide their correctness proof. This work can be viewed as a way to accommodate the ROBBD algorithms to the realm of abstract sorts and uninterpreted functions. The new tool, called NuMDG, accepts an extended SMV language, supporting abstract data sorts. Finally, we present experimental results demonstrating the efficiency of the NuMDG tool and evaluating its performance using a set of benchmarks from the SMV package.

A Case Report of Osteosarcoma of the Skull

引用

Open Journal of Modern Neurosurgery 2014年第3期4卷 105-109页

作者： Bouali sofiene Bouhoula Asma Boubaker Adnene Ben Said Imed Kallel Jalel Aouij Lassaad Jemel Hafedh Department of Neurosurgery Faculty of Medicine University of Tunis El Manar National Institute of Neurology Mongi Ben Hmida Tunis Tunisia

Background: Osteosarcoma is the most common primary malignancy and aggressive neoplasm of bone composed of spindle cells producing osteoid. The incidence of primary osteogenic sarcomas of the skull is about 1% to 2% of all skull tumors. Methods: We present an extraordinary case of osteosarcoma arising in the postero-temporal region of the skull. The clinical features, diagnosis and management are discussed. Results: A 34-year-old woman was operated in our department for mass, fixed to bone in the left postero-temporal area. Histopathology confirmed the diagnosis of osteogenic sarcoma. Conclusion: We review the literature of reported cases of primary osteogenic sarcomas of the skull to discuss the common clinical presentation, evaluation methods, and recommended treatment plans.

Management of Rathke’s Cleft Cysts: About Three Observations

引用

Open Journal of Modern Neurosurgery 2014年第4期4卷 169-172页

Rathke cleft cysts are benign sellar lesions that are generally asymptomatic. Rathke cleft cyst can enlarge and become symptomatic. Surgical therapy is the mainstay of treatment for symptomatic RCC. The optimal surgical strategy remains debatable. We report our experience with this lesion and we discuss the advantages and disadvantages of each technique through a literature review.

人工受精(AI)的结果是降低已经进行过高度选择雄性繁殖力评价的奶牛种群数量。1990-2007年采集502头荷斯坦公牛的42348个精液数据进行贝叶斯框架分析,对过去十几年在人工受精中心常规收集的精液进行精液特征进化和遗传参数的评估。主要考虑的特性是精子数量(VOL)、浓度(CONC)、每次射精的精子数量(NESPZ)、总体精子活力(MM)、个体精子活力(IM)以及解冻后活力(PTM)。研究环境因素随时间的变化时,根据环境和技术条件的改变,年龄的变化、射精顺序、提前收集的时间点(TPC)以及收集和冻结期间的时间点(TCF)对其进行每季度和每周的收集,公牛近交系数(Fi)、永久环境和添加剂遗传因素也被考虑在内,运用贝叶斯因子对此降低模型的使用进行评价。在该模型中对所有的系统效应进行测试并除了Fi影响精子活性和TCF影响PTM之外,得出有力的数据证明模型的正确性。观察中发现除PTM外,环境影响没有系统时间的趋势,这表明环境改变的趋势参与精子冻融的改善。遗传力评价除IM外均处于中度(0.16-0.22),其中存在一个低值(0.07)。精子之间活力的相互作用以及精子活力与CONC之间的相互作用存在较大的遗传相关性(0.38-0.87),VOL与CONC显示出负相关性(-0.13)。如果要求使用这些特征作为判断公牛育种精子活力的指标,需要增大遗传性能有效的选择。
