511, America's traveler information number. Deployment assistance report #4, 511 regional interoperability issues
No full textOn July 21, 2000, the FCC designated 511 as the United States? national travel information telephone number. The FCC ruling leaves nearly all implementation issues and schedules to state and local agencies and telecommunications carriers. In early 2001, mindful of both the opportunity and challenge that 511 presents, the American Association of State Highway and Transportation Officials (AASHTO), in conjunction with many other organizations including the American Public Transportation Association (APTA) and the Intelligent Transportation Society of America (ITS America), with the support of the U.S. DOT, established the 511 Deployment Coalition (Coalition). The Coalition has established as its goal "the timely establishment of a national 511 traveler information service available to a majority of Americans by 2005 that is sustainable and provides value to users." The Coalition recognizes that 511 services will be developed in a bottom-up fashion with state and local transportation agencies establishing services in areas and timeframes determined by them. An increasing number of 511 systems share boundaries and / or have significant travel in between them. This is also true along major travel corridors throughout the country. Callers in one metropolitan area may wish to dial 511 to find information not just for their local travels, but for their entire trip, which might include traveling through other metropolitan areas or regions and crossing state borders. This Deployment Assistance Report (DAR) is an outgrowth of the System Considerations section of the Consistency Guidelines. The purpose of this DAR is to offer 511 implementers technical advice on how to deal with callers who logically want information on transportation facilities and services outside of the area served by the 511 system. With the overlap and varied boundaries of agencies, regions, travel patterns and the unknowns of cellular routing, 511 deployers need to look beyond their borders to make 511 a success with the traveling public. If 511 developers, deployers and operators accomplish regional interoperability through data sharing, then we may achieve national interoperability ultimately as well. This national interoperability may ultimately yield a 511 system where the caller may be asked, "City and state, please." Whether considering a call transfer or a data transfer option, the current expectation is not for full national availability of information via a local 511 service, rather for full information availability within a region plus relevant travel corridors to and from the region. For those implementing systems, this DAR is intended to provide you with the best information available on options for call transfers and data sharing. These are the primary means available today to provide information from outside your region to callers.

511, America's traveler information number. Deployment assistance report #3, 511 and homeland security.
No full textToday, transportation agencies are beginning to address the need for threat and vulnerability assessments, and re-examine how existing emergency management plans will be implemented during a homeland security emergency or alert. Travel information is an important component of emergency management, and the telephone is one of many delivery mechanisms. As 511 systems become more widely deployed, it is reasonable to ask ? what role should 511 systems play during homeland security emergencies and alerts, and what are the organizational, technical, cost, and other impacts of doing so? While it does not provide the solutions, this White Paper highlights the issues and suggests related guidelines, for consideration by the 511 Deployment Coalition Policy Group. This White Paper discusses the challenges and opportunities for 511 systems, their designers, and their operators.

511, America's traveler information number. Deployment assistance report #1, Business models and cost considerations
No full textBusiness models and cost recovery are the critical factors for determining the sustainability of the traveler information service, and 511. In March 2001 the Policy Committee directed the 511 Working Group to investigate plausible business models and the appropriateness of their application to 511. It was agreed that a basic 511 service should be available to the end user at no more than the cost of a local call, and that an extended 511 service could be available typically through the private sector, at an additional cost to the consumer. It is these underlying principals that are incorporated into exploration of the business models and cost considerations for enabling these partnerships, and creating the recommendations herein. In the context of 511, the service will be regarded as new from the perspective of callers who previously haven't been exposed to traveler information services. With this in mind, it's important that 511 be sustainable for the long term so that market acceptance and usage can be assured. The Business Models and Cost Sub-committee prepared this document to educate the other members of the 511 Working Group and the members of the 511 Policy Group on issues salient for migrating a planned or existing traveler information service to utilize the 511 dialing code. In addition, it is understood that this document may be used to educate other entities (public and private) interested in deploying the 511 dialing code for advance traveler information systems.

511, America's travel information number. Deployment assistance report #7, roadway content quality on 511 services
No full textThe first 511 service became operational in the Cincinnati/Northern Kentucky area in July 2001. Less than two years later, over a dozen services are operational across the country serving more than 40 million people who, in total, are currently calling 511 nearly 1 million times a month. Every service in operation provides some form of information associated with roadway conditions. With many of the services likely to have their preponderance of callers interested in roadway conditions, the quality of roadway-related content will in many cases dictate overall satisfaction with 511. The 511 roadway quality ?levels? discussed in this deployment assistance report (DAR) are for the basic 511 telephone travel information service. Roadway data quality needs vary greatly by application: traffic incident detection, long-range system-wide planning / modeling, oversize truck permit routing, construction project report analysis, long-range impacts of suburban development, etc. It is understood that all of these activities may need different levels of data disaggregation and quality. The purpose of this DAR is to provide, in a single document, the most up-to-date information on guidelines, state-of-the-practice, state-of-the-art, implementation experience and lessons learned related to gathering and providing quality roadway content over 511 services. The main audience for this DAR is the planners and implementers of 511 systems. 33p
(Table 1) Distribution of upper Campanian-lower Maestrichtian calcareous nannofossils at DSDP Hole 71-511
No full textCalcareous nannofossils from upper Campanian-lower Maestrichtian Deep Sea Drilling Project Leg 71 Cores 511-23 and 511-24 are described and correlated with assemblages of similar age from piston and drill cores on the Falkland Plateau, South Atlantic Ocean. The Leg 71 cores partially fill a drilling gap of at least 20 meters left within a thick (50 m) carbonate section first drilled by DSDP Leg 36 at Site 327. Cores 511-23 and 511-24 both fall within the upper portion of the Biscutum coronum Zone of Wind and demonstrate an overlap in the range of Monomarginatus quaternarius with the ranges of M. pectinatus, Misceomarginatus pleniporus, and Biscutum coronum across the Campanian/ Maestrichtian boundary. Resolution of the sequence of highest occurrence datums for the latter species must await the recovery of a more complete section. Comparison of the Site 511 assemblages with those from Mas Orcadas Core 07-75-44 to the north confirms earlier speculation that the Falkland Plateau served as an important boundary between major water masses during the Late Cretaceous
Geochemistry, lithology and maceral analysis at DSDP Hole 71-511
No full textThe quantity, type, and maturity of the organic matter in Recent through Upper Jurassic sediments from the Falkland Plateau, DSDP Site 511, have been determined. Sediments were investigated for their hydrocarbon potential by organic carbon and Rock-Eval pyrolysis. Kerogen concentrates were prepared and analyzed in reflected and transmitted light to determine vitrinite reflectance and maceral content. Total extractable organic compounds were analyzed for their elemental composition, and the fraction of the nonaromatic hydrocarbons was determined by capillary column gas chromatography and combined gas chromatography/mass spectrometry.
Three main classes of organic matter can be determined at DSDP Site 511 by a qualitative and quantitative evaluation of microscopic and geochemical results. The Upper Jurassic to lower Albian black shales contain high amounts of organic matter of dominantly marine origin. The content of terrigenous organic matter increases at the base of the black shales, whereas the shallowest black shales near the Aptian/Albian boundary are transitional in composition, with increasing amounts of inert, partly oxidized organic matter which is the dominant component in all Albian through Tertiary sediments investigated.
The organic matter in the black shales has a low level of maturity and has not yet reached the onset of thermal hydrocarbon generation. This is demonstrated by the low amounts of total extractable organic compounds, low percentages of hydrocarbons, and the pattern and composition of nonaromatic hydrocarbons. The observed reflectance of huminite and vitrinite particles (between 0.4% and 0.5% Ro at bottom-hole depth of 632 m) is consistent with this interpretation. Several geochemical parameters indicate, however, a rapid increase in the maturation of organic matter with depth of burial. This appears to result from the relatively high heat flow observed at Site 511. If we relate the level of maturation of the black shales at the bottom of Hole 511 to their present shallow depth of burial, they appear rather mature. On the basis of comparisons with other sedimentary basins of a known geothermal history, a somewhat higher paleotemperature gradient and/or additional overburden are required to give the observed maturity at shallow depth.
A comparison with contemporaneous sediments of DSDP Site 361, Cape Basin, which was the basin adjacent and to the north of the Falkland Plateau during the early stages of the South Atlantic Ocean, demonstrates differences in sedimentological features and in the nature of sedimentary organic matter. We interpret these differences to be the result of the different geological settings for Sites 361 and 511

lncRNA ZFPM2-AS1 promotes retinoblastoma progression by targeting microRNA miR-511-3p/paired box protein 6 (PAX6) axis
No full textLong non-coding RNAs (lncRNAs) have been shown to play crucial roles in retinoblastoma progression. In this study, we aimed to investigate the mechanism of lncRNA ZFPM2-AS1 (ZFPM2-AS1) in retinoblastoma progression. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) and Western blotting assays were performed to determine the expression of lncRNA, microRNA (miRNA), mRNA, and protein. The changes in cell proliferation, apoptosis, and cell migration were assessed by functional experiments. The interaction between ZFPM2-AS1, miR-511-3p, and paired box protein 6 (PAX6) was confirmed by a luciferase assay. Our study found that ZFPM2-AS1 and PAX6 were upregulated, whereas miR-511-3p was downregulated in retinoblastoma. ZFPM2-AS1 inhibition decreased the viability and migration of retinoblastoma cells. We also found that ZFPM2-AS1 targets miR-511-3p to upregulate PAX6 in Y79 and SO-RB50 cells. Moreover, we demonstrated that inhibiting miR-511-3p reversed the negative effects of silencing ZFPM2-AS1 and PAX6 on retinoblastoma cell viability and migration. In conclusion, retinoblastoma development is regulated by the ZFPM2-AS1/511-3p/PAX6 axis.</p
