The Poço das Antas National Biological Reserve is located in Rio de Janeiro State, southeast Brazil. This paper presents information on past environmental characteristics of the area through pollen analysis. Two sedimentary columns were collected and five samples were selected for radiocarbon dating. The following ages of the columns from bottom to top were detected: column 1 - 1.20-1.16 m: 608...

The VAXstation 4000 Model 90 is the latest member of the VAXstation product line. Based on the NVAX CPU, the Model 90 was designed as a module upgrade to the VAXstation 4000 Model 60 system. The Model 90 has 2.7 times the CPU performance of the Model 60 and provides base-level, two-dimensional graphics performance of 266,000 vectors per second. It supports up to 128MB of memory, an SCSI-1 bus i...

The Xilinx FPGA architecture is very regular and gatearray-like, but it is not a simple sea-of-gates. An understanding of the architecture and the resources it provides can make designs become more efficient in both speed and density. This Application Note focuses on the features of the XC4000 architecture and its supporting software that improve design efficiency. It also describes advanced de...

The 720P outdoor dome camera from Bosch is a professional surveillance cameras that provides high quality HD images for demanding security and surveillance network requirements. This robust dome is a true day/night camera offering excellent performance day or night. The camera is also available with a built-in active infrared illuminator that provides high performance in extreme low-light envir...

In this study, we present the results of a comprehensive, landscape-scale remote sensing project at Santa Elena on Parris Island, South Carolina. Substantial occupation at the site extends for over 4000 years and has resulted in a complex array of features dating to different time periods. In addition, there is a 40-year history of archaeological research at the site that includes a large-scale...

We present the discovery a giant low surface-brightness arc, of length ∼ 80 kpc in the Coma Cluster. The arc consists of a diffuse luminous matrix with surface-brightness μB < 26.5 mag arcsec and a number of embedded condensations. It is not associated with any giant galaxy in Coma in particular; neither does it have the properties of a gravitational arc. We argue that a fast interaction betwee...

The overall goal of the paper is to understand the progress of the design and implementation of China's New Cooperative Medical System (NCMS) program between 2004 (the second year of the program) and 2007. In the paper we seek to assess some of the strengths and weaknesses of the program using a panel of national-representative, household survey data that were collected in 2005 and early 2008. ...

Recall, from Theorem 8.1-2 on page 490 in [4], that a random process X(t) with autocorrelation function RXX(t1, t2) has a m.s. derivative at time t if ∂RXX(t1, t2)/∂t1∂t2 exists at t1 = t2 = t. Furthermore, we recall that the correlation function RXX(t1, t2) is related to the covariance function KXX(t1, t2) as follows. RXX(t1, t2) = KXX(t1, t2) + μX(t1)μX(t2) (1) For this problem we have a cons...
