Nucleoside triphosphates having a 3′-ONH2 blocking group have been prepared with and without fluorescent tags on their nucleobases. DNA polymerases were identified that accepted these, adding single nucleotide to the 3′-end of primer in template-directed extension reaction then stops. Nitrite chemistry was developed cleave under mild conditions allow continued extension. Extension-cleavage-extension cycles solution demonstrated untagged nucleotides mixtures tagged nucleotides. Multiple...
This study examines the relationships between land-use, transportation infrastructure, household, and individual characteristics resulting average daily trip distances using data from 1999 Mid-Ohio Area Household Travel Survey. Spatial error models are developed to analyze determinants of at person level. First, new neighborhood categories created K-means cluster analysis several land-use built-environment variables. Then, these (such as central city residential areas, medium-density...
Abstract Citizen involvement in environmental policy setting is important for insuring viability. However, traditional public meetings are criticized being an ineffective means of conveying information, especially complex issues such as watershed management. An interactive technology-based approach to provides a promising alternative. This pilot study compares knowledge, commitment and satisfaction levels two groups participants at meeting: one group attended meeting format the other format....
Abstract Various computing subdisciplines, such as computer science and software engineering, each have their own curricular guidelines. They can be very difficult to understand compare for people prospective students, industry personnel, even faculty members. This is compounded by a lack of information surrounding undergraduate topics via visual methods. paper describes two experimental activities where the objective explore possibility obtaining quantitative data sets necessary...
The carbon footprint of daily travel for an individual household is based on the types vehicles that owns, their fuel efficiency, and number miles traveled (Federal Highway Administration, 2009 Federal Administration. (2009). "carbon footprint" travel. NHTS Brief, U.S. Department Transportation. https://nhts.ornl.gov/briefs/Carbon%20Footprint%20of%20Travel.pdf. [Google Scholar]). Therefore, usage a owns are informational to overall sustainable planning. This study develops multinomial logit...
High Performance Computing (HPC) is the ability to process data and perform complex calculations at extremely high speeds. Current HPC platforms can achieve on order of quadrillions per second, with quintillions horizon. The past three decades witnessed a vast increase in use across different scientific, engineering, business communities problems such as sequencing genome, predicting climate changes, designing modern aerodynamics, or establishing customer preferences. Although has been well...
The goal of this study is to develop and apply a methodology for delineating optimal land-use patterns that minimize peak runoff flow at watershed outlets by coupling hydrological model model. Under the assumption supported in prior research nonpoint source (NPS) pollution positively correlated with surface volume, then yields pollution. A simulation developed modified spatially explicit Soil Conservation Service (SCS) curve number method analyze geographical impacts land uses. An...
A hierarchical optimization framework is developed to analyze spatially complex watersheds and support spatial decision making for land management practices. watershed subdivided into smaller units according its hierarchy, a three‐level approach determines optimal allocations at the subarea, catchment, 30 m cell levels. storm water runoff simulation model used generate peak discharge pseudo data, under different use patterns. The results are inputs regression analyses, functional...
Abstract Environmental modeling has long been a recognized part of environmental risk assessment. Traditionally, models have deterministic for specific processes over small areas using spatially aggregated subunits data collection and processing. For an analysis factors on regional scale, such are not always appropriate because uncertainties in the processes, heterogeneity environment, extensive requirements. Under circumstances, statistical environment can offer useful insights it deals...
Extending expertise in parallel computing is critical to all those using high performance gain insights into science and engineering problems. Many campuses do not offer such a course because of load limits, lack faculty expertise, and/or access appropriate resources. MOOCs for this type are difficult scale both constraints on resources as well the need individual attention with programming Using blended online collaborating that academic credit their students, we have been able facilitate...
Nine Ohio higher education institutions combined expertise to implement an interinstitutional, competency-based undergraduate minor curriculum in computational science. Key program elements include the definition of program's interdisciplinary competency requirements, sharable instructional modules, and interinstitutional agreements for cross registration. Many courses are offered remotely, so students can access science instruction likely unavailable at their home institutions. The is a...
It has been well documented for more than 30 years, that significantly effort is needed to prepare the HPC workforce today and into future. The Blue Waters Virtual School of Computational Science (VSCSE) provides an innovative model addressing this critical need. VSCSE uses a Small Private Online Course (SPOC) approach providing graduate level credit courses students at multiple institutions. In paper, we describe rationale approach, description implementation, findings from external...
As parallel computing grows and becomes an essential part of computer science, tools must be developed to help grade assignments for large courses, especially with the prevalence Massive Open Online Courses (MOOCs) increasing in recent years. This paper describes some general challenges related building autograder code suggestions sample design decisions covering presented assignments. The explores results experiences from using these autograders enable XSEDE 2013 2014 Parallel Computing...
We propose to address the issue of quality digital library objects in Computational Science Education Reference Desk by applying a verification, validation, and accreditation workflow review learning objects.
Progress in science and engineering is increasingly tied to the effective use of computational modeling on high-performance computing systems. Expertise parallel techniques therefore required, given current architecture those Many campuses don't offer such a course because load limits, lack faculty expertise, and/or access appropriate resources. As part XSEDE project, an initial MOOC-style proved be ineffective at resolving this problem. A subsequent blended online with collaborating from...
Abstract Environmental planners and other environmental professionals work extensively with soil survey information as a major component of land use planning. Ratings soils for various urban uses are prepared by the U.S. Soil Conservation Service (SCS) frequently applied to planning decisions. Recent changes in SCS procedures indicate some potential past inconsistencies ratings which might mislead planners. In this research, from three different county surveys Ohio townships were tested...
There is a saying, "Everything changes, but nothing changes." We are realizing rapid technological revolution in the development, deployment, and application of computing technologies within every discipline sector society. Yet, our ability to respond well-documented need for large, diverse, computationally literate workforce remains challenge. summarize 35 years lessons learned preparing that can inform efforts address this have pursued multiprong approach reach instructors, researchers,...
