The epidemic threshold theorem with social and contact heterogeneity
(SPIE-INT SOC OPTICAL ENGINEERING, 2008-03-17)
The threshold theorem of an epidemic SIR model was compared when infectious and susceptible individuals have homogeneous mixing and heterogeneous social status and when individuals of random networks have contact heterogeneity. ...
An optimal approach to the multiple-depot heterogeneous vehicle routing problem with time window and capacity constraints
(Planta Piloto de Ingeniería Química, 2003-10)
The vehicle routing problem (VRP) has become a crucial industrial issue for its impact on product distribution costs. Though quite important in practice, the time-constrained version of the VRP accounting for several types ...
Projeto de redes de sensores sem fio heterogêneas utilizando os conceitos de redes small word
(Universidade Federal de Minas GeraisUFMG, 2011-09-23)
A typical Wireless Sensor Network (WSN) assumes a homogeneous set of nodes in terms of capabilities. However, this kind of network suffers from poor fundamental limitations of latency during the data communication. Another ...
A triple point induced by targeted autonomization on interdependent scale-free networks
(IOP Publishing, 2014-02)
Recent studies have shown that in interdependent networks an initial failure of a fraction 1 − p of nodes in one network, exposes the system to a cascade of failures. Therefore it is important to develop efficient strategies ...
Pseudo-Lignin Content Decreased with Hemicellulose and Lignin Removal, Improving Cellulose Accessibility, and Enzymatic Digestibility
(2020-01-01)
The sugarcane bagasse is a heterogeneous material and needs a pretreatment to breakdown its complex structure to make cellulose accessible to enzyme action. This study aimed to evaluate pseudo-lignin formation, enzymatic ...
Genome-Wide Copy Number Analysis in a Family With p.G533C RET Mutation and Medullary Thyroid Carcinoma Identified Regions Potentially Associated With a Higher Predisposition to Lymph Node Metastasis
(Endocrine Soc, 2014-06-01)
Context: Our group described a p.G533C RET gene mutation in a large family with multiple endocrine neoplasia type 2 syndrome. Clinical heterogeneity, primarily associated with the presence of lymph node metastases, was ...
