Poor rich demarcation of matthew effect on scale-free systems and its application

引用

Chinese Physics B 2011年第4期20卷 27-32页

作者：闫栋董明 abdelaziz Bourasc 于随然 School of mechanical Engineering Shanghai Jiao Tong University College of Economics & management Shanghai Jiao Tong University IUT Lumière Technology Institute Université Lumière Lyon 2

In a scale-free network, only a minority of nodes are connected very often, while the majority of nodes are connected rarely. However, what is the ratio of minority nodes to majority nodes resulting from the matthew effect？ In this paper, based on a simple preferential random model, the poor-rich demarcation points are found to vary in a limited range, and form a poor-rich demarcation interval that approximates to k/m E [3,4]. As a result, the （cumulative） degree distribution of a scale-free network can be divided into three intervals： the poor interval, the demarcation interval and the rich interval. The inequality of the degree distribution in each interval is measured. Finally, the matthew effect is applied to the ABC analysis of project management.

A COmPOUND POISSON mODEL FOR LEARNING DISCRETE BAYESIAN NETWORKS

引用

Acta mathematica Scientia 2013年第6期33卷 1767-1784页

作者： abdelaziz GHRIBI Afif mASmOUDI Laboratory of Physic-mathematics University of Sfax Laboratory of Probability and Statistics University of Sfax

We introduce here the concept of Bayesian networks, in compound Poisson model, which provides a graphical modeling framework that encodes the joint probability distribution for a set of random variables within a directed acyclic graph. We suggest an approach proposal which offers a new mixed implicit estimator. We show that the implicit approach applied in compound Poisson model is very attractive for its ability to understand data and does not require any prior information. A comparative study between learned estimates given by implicit and by standard Bayesian approaches is established. Under some conditions and based on minimal squared error calculations, we show that the mixed implicit estimator is better than the standard Bayesian and the maximum likelihood estimators. We illustrate our approach by considering a simulation study in the context of mobile communication networks.

Doppler ultrasonography in living donor liver transplantation recipients: Intra- and post-operative vascular complications

引用

World Journal of Gastroenterology 2016年第27期22卷 6145-6172页

作者： Omar abdelaziz Hussein Attia Department of Diagnostic and Interventional Radiology Cairo University Hospitals Department of Diagnostic and Interventional Radiology National Cancer Institute Cairo University

Living-donor liver transplantation has provided a solution to the severe lack of cadaver grafts for the replacement of liver afflicted with end-stage cirrhosis, fulminant disease, or inborn errors of metabolism. Vascular complications remain the most serious complications and a common cause for graft failure after hepatic transplantation. Doppler ultrasound remains the primary radiological imaging modality for the diagnosis of such complications. This article presents a brief review of intra- and post-operative living donor liver transplantation anatomy and a synopsis of the role of ultrasonography and color Doppler in evaluating the graft vascular haemodynamics both during surgery and post-operatively in accurately defining the early vascular complications. Intra-operative ultrasonography of the liver graft provides the surgeon with useful real-time diagnostic and staging information that may result in an alteration in the planned surgical approach and corrections of surgical complications during the procedure of vascular anastomoses. The relevant intraoperative anatomy and the spectrum of normal and abnormal findings are described. Ultrasonography and color Doppler also provides the clinicians and surgeons early post-operative potential developmental complications that may occur during hospital stay. Early detection and thus early problem solving can make the difference between graft survival and failure.

In this research,a promising class of insensitive and high-energy dense biopolymers,which contain nitrogen-rich 1H-tetrazol-1-yl acetate and nitrate ester functional groups,was successfully synthesized through tetrazole derivatization and nitration of cellulose and its micro-sized derivative(TNCN and TCmCN).Their molecular structures,physicochemical properties,thermal behaviors,mechanical sensitivities and detonation performances were studied and compared to those of the corresponding nitrocellulose and nitrated micro-sized cellulose(NCN and CmCN).The developed energetic TNCN and TCmCN exhibited insensitive character with excellent features such as density of 1.710 g/cm3and 1.726 g/cm3,nitrogen content of 20.95%and 22.59%,and detonation velocity of 7552 m/s and 7786 m/s,respectively,and thereby demonstrate their potential applications as new generation of energetic biopolymers to substitute the common ***,thermal results showed that the designed nitrated and chemical modified cellulosic biopolymers displayed good thermal stability with multistep decomposition *** results enrich future prospects for the design of promising insensitive and high-energy dense cellulose-rich materials and commence a new chapter in this field.
