While the capability approach is increasingly being adopted for evaluating well-being and social justice in the field of human development,this approach in disaster research has remained *** research thus seeks to address the disaster risk that humans face through a lens of capabilities,with a focus on the lives of people with disabilities.A multi-case study approach was adopted and two rural communes in Vietnam were selected as study con *** were collected using focus group discussions and interviews that involved people with disabilities,parents/caregivers of people with intellectual/psychosocial disabilities,and representatives from related *** was found that people with disabilities are affected by disasters due to the lack of capabilities that they value in coping with disasters.A range of capabilities that people with disabilities value was revealed in the study sites,with many being valued not only in times of disasters but also in daily *** findings also highlight that,to actualize their valued capabilities,people with disabilities need access not only to resources but also to the factors that enable them to convert the resources to their valued *** most cases,the limitations to the achievement of capabilities are related to the external environment.

STABILITY ANALYSIS OF A COMPUTER VIRUS PROPAGATION MODEL WITH ANTIDOTE IN VULNERABLE SYSTEM

引用

Acta Mathematica Scientia 2016年第1期36卷 49-61页

作者： Nguyen Huu khanh Nguyen Bich HUY Department of Mathematics College of Natural SciencesCan Tho University Departmet of Mathematics Ho Chi Minh University of Education

We study a proposed model describing the propagation of computer virus in the network with antidote in vulnerable system. Mathematical analysis shows that dynamics of the spread of computer viruses is determined by the threshold Ro. If Ro 〈 1, the virusfree equilibrium is globally asymptotically stable, and if R0 〉 1, the endemic equilibrium is globally asymptotically stable. Lyapunov functional method as well as geometric approach are used for proving the global stability of equilibria. A numerical investigation is carried out to confirm the analytical results. Through parameter analysis, some effective strategies for eliminating viruses are suggested.

Treatment of portal vein thrombosis in cirrhosis with anticoagulation-more than meets the eye?

Hepatobiliary Surgery and Nutrition 2024年第2期13卷 321-324页

作者： ton Lisman Surgical Research Laboratory and Section of Hepatobiliary Surgery and Liver Transplantation Department of SurgeryUniversity of GroningenUniversity Medical Center GroningenGroningenThe Netherlands

Portal vein thrombosis(PVT)is a common complication in patients with advanced chronic liver disease(i.e.,cirrhosis).In contrast to other thrombotic diseases,PVT in patients with cirrhosis is frequently asymptomatic and discovered incidentally during routine imaging *** is ongoing debate on whether all patients with PVT require treatment as it is unclear whether PVT is a relatively innocent bystander or whether PVT worsens disease progression(1).Treatment may be required in patients with>50%occlusion of the portal vein who are transplant candidates to avoid thrombosis progression that may hinder a future liver transplantation or cause progression of portal hypertension(2).Current treatment consists of therapeutic anticoagulation with vitamin K antagonists,heparins,or direct oral *** anticoagulant therapy for cirrhotic PVT is relatively safe,the efficacy is modest,with meta-analyses demonstrating recanalization of the portal vein in~30-40%of patients without anticoagulation,and~60-70%with anticoagulation(3,4).

Assessment of ship manoeuvrability by using a coupling between a nonlinear transient manoeuvring model and mathematical programming techniques

引用

Journal of Hydrodynamics 2013年第5期25卷 788-804页

作者： TRAN khanh Toan OUAHSINE Abdellatif NACEUR Hakim EL WASSIFI Karima Laboratoire Roberval Université de Technologie de Compiègne Laboratoire LAMIH Université de Valenciennes Université Cadi Ayyad Faculté des Sciences et Techniques

In this paper, a numerical method based on a coupling between a mathematical model of nonlinear transient ship manoeuvring motion in the horizontal plane and Mathematical Programming （MP） techniques is proposed. The aim of the proposed procedure is an efficient estimation of optimal ship hydrodynamic parameters in a dynamic model at the early design stage. The proposed procedure has been validated through turning circle and zigzag manoeuvres based on experimental data of sea trials of the 190 000- dwt oil tanker. Comparisons between experimental and computed data show a good agreement of overall tendency in manoeuvring traiectories.
