This paper describes the EPA nonroad mobile source emissions model now under development. The NONROAD model, as it is called, will be released in a beta version in early 1998, and then in final version in late summer 1998. The current working version of the model estimates emissions from nonroad agricultural, construction, industrial, recreational marine, and lawn and garden equipment; emission...

Direct Memory Access DMA is frequently used to transfer data between the main memory of a host computer and the interconnection network in order to free the host processor from the burden of the trans fer DMA operations are traditionally initiated by the operating system kernel mainly to prevent one appli cation from tampering with another applications data Recent architecture trends suggest th...

The Intelligent Payload Experiment (IPEX) is a CubeSat mission to flight validate technologies for onboard instrument processing and autonomous operations for NASA’s Earth Science Technologies Office (ESTO). Specifically IPEX is to demonstrate onboard instrument processing and product generation technologies for the Intelligent Payload Module (IPM) of the proposed Hyperspectral Infra-red Imager...

THE DETROIT METRO CHAPTER OF SOCIETY FOR INFORMATION Display (SID) held its 29th Annual Vehicle Displays and Interfaces Symposium Exposition (VDS) as an in-person event September 27 28 in Novi, Michigan. While not completely returning to pre-pandemic levels, VDS 2022 had 539 registered attendees 51 exhibitors. The annual symposium is designed disseminate information among designers, engineers, ...

The InfoHarnessTM system is aimed at providing integrated and rapid access to huge amounts of heterogeneous information independent of its type, representation, and location. InfoHarness is intended to provide advanced search and browsing capabilities without imposing the burden of restructuring, reformatting, or relocating information on information suppliers. This is achieved through creating...

•Colon tumors contain therapy-resistant quiescent cancer stem cells (qCSCs)•qCSC gene expression mirrors that of the regenerating gut•qCSCs are enriched for p53 signaling genes•qCSC elimination may be achieved by inhibiting downstream targets Recent data suggest (qCSCs) source relapse in colon cancer. Here, using patient-derived organoids and xenografts, we identify rare long-term label-retaini...

Visual programming approaches are limited in their usefulness if they do not include a profile of their users that defines exactly who is attempting to solve what kind of problems using which tools and why. Without such a definition, visual programming approaches can end up as solutions in search of problems. Reconceptualizing — programming environments as layered behavior processors in the con...

p53-mediated apoptosis in baby rat kidney (BRK) cell lines transformed by EIA and p53(vaIl35) requires a transcriptionally functional p53. Coexpression of the El B 19K protein in BRK cell lines transformed by EIA and p53(vaIl35) rescues cells from p53-mediated apoptosis, and this is paralleled by the absence of both lamin and poly(ADP-nbose) polymerase cleavage. Therefore, the role of interleuk...

Expression vectors for human a-interferon (Hu-IFN-a) .11. a sitespecific mutant |Ser"6]Hu-IFN-aJl, and Hu-IFN-aJ/C or Hu-IFN-aC/ J hybrids were constructed and expressed in Escherichìacoli. These interferons and others were purified by immunoaffinity chromatography with a monoclonal antibody against human a-interferon. Their antiviral activity and ability to stimulate natural killer cell activ...

Current microprocessors exploit high levels of instruction level parallelism ILP through techniques such as multiple issue dynamic scheduling and non blocking reads This paper presents the rst detailed analysis of the impact of such processors on shared memory multiprocessors using a detailed execution driven simulator Using this analysis we also exam ine the validity of common direct execution...
