A short summary of constraints on the parameter space of supersymmetric models is given. Experimental limits from high energy colliders, electroweak precision data, flavor and Higgs physics, and cosmology are considered. The main focus is on the MSSM with conserved R-and CP-parity and minimal flavor violation, but more general scenarios and extended models(More)
OBJECTIVE To develop a model to assess different strategies of pertussis booster vaccination in the city of São Paulo. METHODS A dynamic stationary age-dependent compartmental model with waning immunity was developed. The "Who Acquires Infection from Whom" matrix was used to modeling age-dependent transmission rates. There were tested different strategies(More)
The wireless network evolution has allowed that the handset technology provides a broad and new set of resources and facilities to their users. However, this evolution is also increasing the number and complexity of testing prior to handsets deployment, so that test automation is an essential need to deal with this recent scenario. This paper presents all(More)
OBJECTIVE To evaluate the cost-effectiveness of introducing universal vaccination of adults aged 60 years with the 23-valent pneumococcal polysaccharide vaccine (PPV23) into the National Immunization Program (NIP) in Brazil. METHODS Economic evaluation using a Markov model to compare two strategies: (1) universal vaccination of adults aged 60 years with(More)
