Many Internet customers use network address translation (NAT) when connecting to the Internet. To understand the extend of NAT usage and its implications, we explore NAT usage in residential broadband networks based on observations from more than 20,000 DSL lines. We present a unique approach for detecting the presence of NAT and for estimating the number of hosts connected behind a NAT gateway...
Network Address Translator (NAT) has brought up many changes and opportunities to the Internet. How do the ubiquitous and pervasive applications coexist with NAT and interoperate with each other? In this article, we discuss the essence of NAT sensitive applications as well as the challenge and response for various NAT traversal solutions. All questions pointed to redesign a new NAT framework wi...
BACKGROUND The risk of viral infection associated with blood transfusion is lower than ever before because of aggressive screening and testing practices. NAT technology has lowered that risk even further but at an additional cost to the health-care system. STUDY DESIGN AND METHODS Marginal cost-effectiveness of NAT for HIV, HCV, and HBV in whole-blood donations was calculated with a previousl...
Mammalian genomes encode numerous cis-natural antisense transcripts (cis-NATs). The extent to which these cis-NATs are actively regulated and ultimately functionally relevant, as opposed to transcriptional noise, remains a matter of debate. To address this issue, we analyzed the chromatin environment and RNA Pol II binding properties of human cis-NAT promoters genome-wide. Cap analysis of gene ...
Natural antisense transcripts (NATs) are a prominent and complex class of regulatory RNAs. Using strand-specific RNA sequencing, we identified 1769 sense and antisense transcript pairs (NAT pairs) in two maize inbreds with different sensitivity to drought, as well as in two derivative recombination inbred lines (RILs). A significantly higher proportion of NATs relative to non-NATs are specifica...
This document identifies two deployment scenarios that have arisen from the unconventional network topologies formed using Network Address Translator (NAT) devices. First, the simplicity of administering networks through the combination of NAT and DHCP has increasingly lead to the deployment of multi-level inter-connected private networks involving overlapping private IP address spaces. Second,...
Circadian melatonin production in the pineal gland and retina is under the control of serotonin N-acetyltransferase (NAT) and hydroxyindole-O-methyltransferase. Because NAT activity varies diurnally, it has been considered both the melatonin rhythm-generating enzyme and the rate-limiting enzyme of melatonin synthesis. In rats with dramatically reduced NAT activity due to a H28Y mutation in NAT,...
West Nile virus (WNV) is transmitted to humans primarily by infected mosquitoes. However, WNV also can be transmitted through infected blood products or solid organs (1). Since 2003, the U.S. blood supply has been routinely screened for WNV RNA. The Food and Drug Administration (FDA) recommends that blood collection agencies perform WNV nucleic acid testing (NAT) year-round on all blood donatio...
In the present study we have measured excitation functions for nuclear reactions $^{100}$Mo($\alpha$,n)$^{103}$Ru, $^{nat}$Mo($\alpha$,x)$^{97}$Ru, $^{nat}$Mo($\alpha$,x)$^{95}$Ru, $^{nat}$Mo($\alpha$,x)$^{96g}$Tc, $^{nat}$Mo($\alpha$,x)$^{95g}$Tc and $^{nat}$Mo($\alpha$,x)$^{94g}$Tc in energy range 11-32 MeV. We used stacked foil activation technique followed by off-line gamma ray spectroscopy...
