Atmospheric forcing data, tabulated by Donelan et al. （1997.J Phys Oceanog, 27：2087-2099）, were collected from a mast on the foredeck of a SWATH （small water-plane area, twin hull） ship in deep sea off the State of Virginia during the surface wave dynamics experiment. These data are representative of low to moderate wind regimes. The aerodynamic roughness length is determined by using the Charnock relationship. The intercomparison shows that the Louis scheme and the COARE algorithm underestimate the friction velocity by 6% and 3% respectively under pure wind sea conditions, 15% and 13% respectively under cross swell conditions, and 21% and 17% respectively under counter swell conditions. The analysis shows that these underestimations were caused by the method chosen to determine the aerodynamic roughness length because it significantly underestimates the aerodynamic roughness length. It is especially true under the cross swell and counter swell conditions.展开更多

For those who miss follow-up visits, some of them might learn that the event of interest has already happened when they come back. In this case, not only are their event times interval-censored, but also their time-dependent measurements are incomplete. This problem was motivated by a national longitudinal survey of youth data. Maximum likelihood estimation (MLE) method based on expectation-maximization (EM) algorithm is used for parameter estimation. Then missing information principle is applied to estimate the variance-covariance matrix of the MLEs. Simulation studies demonstrate that the proposed method works well in terms of bias, standard error, and power for samples of moderate size. The national longitudinal survey of youth 1997 (NLSY97) data is analyzed for illustration.展开更多

We show here a review on infections of the central nervous system by St. Louis Encephalitis, Rocio and West Nile Flaviviruses in Brazil, 2004-2014. In the last 10 years, serologic surveys in horses showed high proportions of seropositive animals which point out that SLEV and ROCV have circulated infecting horses in west-central, southeast and other regions of Brazil and that WNV has been introduced into Brazil and circulates mostly in Pantanal region. However humans infected by WNV have not been reported. In the State of Sao Paulo: SLEV was isolated from a case clinically diagnosed as dengue in 2004;in 2006, 6 SLEV patients including 3 cases of menigoencephalitis were reported in the middle of a large epidemic of dengue type 3;and in 2008, 1 patient with acute febrile illness that was IgM-positive for dengue was found infected by SLEV by detection of the virus genome. In 2010, ROCV genome was detected in the cerebrospinal fluids of 2 patients from the northern region with meningoenchephalitis and also AIDS. This was the first report of infections by ROCV in the last 34 years and curiously, it occured more than 2000 km from where the virus was firstly found. It is necessary to improve the surveillance of SLEV, ROCV and WNV in Brazil.展开更多
