Pilot Study of Applicability of a Generic Microprocessor Assembly Language

The purpose of this investigation is to research the utility of a standardized generic microprocessor assembly language. More precisely, use of a generic language implementation on a given microprocessor and its effect on programmer productivity will be investigated. Programmer productivity will be scored in terms of an inverse function of the time taken to complete a programming task correctly. Shorter times imply better programmer productivity and longer times imply the opposit

Impacts of Transportation Infrastructure on Stormwater and Surfaces Waters in Chittenden County, Vermont, USA

Transportation infrastructure is a major source of stormwater runoff that can alter hydrology and contribute significant loading of nutrients, sediment, and other pollutants to surface waters. These increased loads can contribute to impairment of streams in developed areas and ultimately to Lake Champlain. In this study we selected six watersheds that represent a range of road types (gravel and paved) and road densities (rural, suburban, and urban) present in Chittenden County, one of the most developed areas in Vermont. The location and density of road networks were characterized and quantified for each watershed using GIS analysis. Monitoring stations in each watershed were constructed and instrumented to measure discharge and water quality parameters continuously from spring through early winter. Storm event composite samples and monthly water chemistry grab samples were collected and analyzed for total nutrients, chloride, and total suspended sediments. Results from this study show that road type and road density are closely linked with the level of impairment in each watershed. Total phosphorus and total nitrogen from storm event composite samples and monthly grab samples significantly increased along a gradient of increasing road network density. Chloride concentrations increased several orders of magnitude along this same gradient. With the exception of Alder brook where total suspended sediment (TSS) concentrations tended to be high, there were no significant differences in TSS concentrations between rural and developed watersheds. The event TSS concentrations in the rural streams were slightly higher than we expected and the event and base TSS concentrations in the developed streams were somewhat lower than we expected, suggesting that the unpaved roads in the rural watersheds might contribute to stormwater runoff loads and that sediment control, at least, in the developed watersheds might be fairly effective. The overall results from this study show that local roads are significant source of impairment for streams in the Chittenden County area. Most of these roads are municipal roads that are not under to management of the Vermont Agency of Transportation. Thus, local actions will be necessary to control runoff from these roads

Quantum computational renormalization in the Haldane phase

Single-spin measurements on the ground state of an interacting spin lattice can be used to perform a quantum computation. We show how such measurements can mimic renormalization group transformations and remove the short-ranged variations of the state that can reduce the fidelity of a computation. This suggests that the quantum computational ability of a spin lattice could be a robust property of a quantum phase. We illustrate our idea with the ground state of a spin-1 chain, which can serve as a quantum computational wire not only at the Affleck-Kennedy-Lieb-Tasaki point, but within the rotationally-invariant Haldane phase.Comment: v2: 4 pages, 3 figures; improved description of buffering scheme and connection to string operators. v3: final published versio

CrY2H-seq: a massively multiplexed assay for deep-coverage interactome mapping.

Broad-scale protein-protein interaction mapping is a major challenge given the cost, time, and sensitivity constraints of existing technologies. Here, we present a massively multiplexed yeast two-hybrid method, CrY2H-seq, which uses a Cre recombinase interaction reporter to intracellularly fuse the coding sequences of two interacting proteins and next-generation DNA sequencing to identify these interactions en masse. We applied CrY2H-seq to investigate sparsely annotated Arabidopsis thaliana transcription factors interactions. By performing ten independent screens testing a total of 36 million binary interaction combinations, and uncovering a network of 8,577 interactions among 1,453 transcription factors, we demonstrate CrY2H-seq's improved screening capacity, efficiency, and sensitivity over those of existing technologies. The deep-coverage network resource we call AtTFIN-1 recapitulates one-third of previously reported interactions derived from diverse methods, expands the number of known plant transcription factor interactions by three-fold, and reveals previously unknown family-specific interaction module associations with plant reproductive development, root architecture, and circadian coordination

Efficient diagnostics for quantum error correction

Fault-tolerant quantum computing will require accurate estimates of the resource overhead, but standard metrics such as gate fidelity and diamond distance have been shown to be poor predictors of logical performance. We present a scalable experimental approach based on Pauli error reconstruction to predict the performance of concatenated codes. Numerical evidence demonstrates that our method significantly outperforms predictions based on standard error metrics for various error models, even with limited data. We illustrate how this method assists in the selection of error correction schemes.Comment: 5 pages + 11 page appendix, 6 figure

Voices from the Classroom: Experiences of Teachers of Deaf Students with Additional Disabilities

The purpose of this research is to investigate experiences of K-12 classroom teachers of deaf students with additional disabilities. Today, more deaf and hard of hearing students are identified as having additional disabilities (Bruce, DiNatale & Ford, 2008; Ewing, 2011; Gallaudet Research Institute, 2011; Jones, Jones & Ewing, 2006; Mitchell & Karchmer, 2004); there is a need to explore ways of providing educational services to these students. Utilizing a phenomenological design, data were collected using survey questionnaires, focus groups and individual interviews. Several themes emerged, such as the typical school day, previous training, and continuous professional development. Understanding the experiences of the K- 12 teachers can provide valuable information for deaf education teacher preparation programs
