Effective operator contributions to the oblique parameters

We present a model and process independent study of the contributions from non-Standard Model physics to the oblique parameters S, T and U. We show that within an effective lagrangian parameterization the expressions for the oblique parameters in terms of observables are consistent, while those in terms of the vector-boson vacuum polarization tensors are ambiguous. We obtain the constraints on the scale of new physics derived from current data on S, T and U and note that deviations in U from its Standard Model value would favor a scenario where the underlying physics does not decouple.Comment: 13 pages, RevTe

Its primary scientific objectives are to measure the elemental and isotopic composition of solar energetic particles, anomalous cosmic rays, and galactic cosmic rays over the energy range from approximately one to several hundred MeV per nucleon. The SAMPEX mission objectives are outlined and the DSN support requirements are defined through the presentation of tables and narratives describing the spacecraft flight profile; DSN support coverage; frequency assignments; support parameters for telemetry, command and support systems; and tracking support responsibility

Human Papillomavirus and Cervical Cancer

The pathophysiology of cervical cancer and human papillomavirus (HPV) is important for practitioners to understand to treat patients accordingly. The correlation between HPV and cervical cancer is a significant concept to learn and teach patients as it is different than other disease processes because HPV is a virus that causes cervical cancer. By using ten references information was gathered to support this presentation. Up to date research from government agencies and scholarly resources was used from the last four years. Research was used to retrieve similar information supporting the pathophysiology, signs and symptoms, and implications of nursing care for patients with HPV and cervical cancer. Cervical intraepithelial neoplasia (CIN) or dysplasia is also included to further explain the progression of the disease. Conclusive evidence was discovered pertaining to prevention of HPV to avoid the progression to cervical cancer. Practitioners, patients and families alike can use this gathered research to better understand this disease process

Assessing the Economic and Environmental Impacts associated with Current Street Lighting Technologies

Rising global energy demand and natural disasters continuously threaten energy supplies and prices. As a result, the U.S. government has mandated all government agencies to reduce energy consumption in order to minimize dependence on foreign energy supply and reduce costs. Concern over carbon emissions and environmental impacts has also been expressed in these mandates. One solution may be to invest in newer lighting technologies, such as light-emitting diode (LED) and electrodeless induction, in order to reduce the energy consumption, environmental impact, and costs required for both exterior roadway and parking lot lighting applications. This research compared these lighting technologies with high-pressure sodium (HPS) lighting technology at 56 Air Force installations to assess the economic and environmental consequences associated with each technology over the product life-cycle. This study utilized Building Life-Cycle Cost 5 and Economic Input-Output Life Cycle Assessment software packages to perform the analysis. Both the LED and electrodeless induction technologies showed moderate economic savings and less environmental impact when compared to HPS technology. The overall economic life-cycle costs for LED and induction lighting were 21% and 23% less, respectively, than HPS lighting. Environmental life-cycle assessment showed reductions of 55% and 45% for LED and induction technologies, respectively, compared to HPS lighting

STUDY OF COMPOSITE MATERIAL FAILURE UNDER TENSILE AND CYCLIC LOADING

Composite structures continue to gain popularity in engineering applications as they offer great strength to weight ratios, design flexibility and can last a long time. However, they are not exempt from catastrophic failure and fail without warning. Unlike metals, composites do not have defined endurance limits or established S-N curves, and their failure mechanism under cyclic loading is still largely underdeveloped. This thesis aimed to use a multiscale approach to predict the residual strength of glass fiber composites (GFC) after cyclic loading, create an S-N curve for GFC and glass fiber bundles (GFB) and assess recently proposed universal failure criteria for notched specimens. GFC and GFB specimens' behavior were analyzed under tensile and cyclic loading. Polymethyl methacrylate (PMMA) and laminated carbon fiber composites (CFC) with cross-ply (CP) and quasi-isotropic (QI) orientations containing various notch shapes were tensile tested and analyzed in Ansys. As a result, a probabilistic model for residual strength after cyclic loading for GFC was created and agreed with the experimental data. Additionally, S-N curves were generated for GFC and GFB. The results of the proposed failure criteria also agreed very well against experimental data for the materials tested with various notch types.Lieutenant, United States Coast GuardApproved for public release.

Development of Functional Requirements for a High-capacity Airspace System

NASA along with other researchers visualizes a future where more aircraft will transport passengers or goods around the world. Thus, they envision increasing air capacity from 10 to 100 times more than the current system without any reduction in efficiency or safety. Many models are being proposed that comply with the necessary requirements to form part of the method needed. However, knowing which of the proposed methods have the most desirable characteristics, such as efficiency and safety, are yet to be determined. For this reason, a standardized method to compare and assess them has to be developed, since is not possible to apply them all. An approach to this issue is establishing functional requirements, which are a set of standards that assess and compare performances of new models. Thus, this research is focused on identifying quality measures, which are measures of the requirements, in order to establish functional requirements. As for the first step, measures regarding air transportation system were collected and analyzed by literature review and surveys to determine the potential candidates. As a result, the final potential quality measure candidates were obtained that lead us to determine the ideal measures of the functional requirements and three types of quality measures were discovered. These measures of the functional requirements will constitute a standard to assess new models being proposed and determine the most desirable results

Sediment Microbiomes Associated with Critical Habitat of the Juvenile American Horseshoe Crab; Limulus Polyphemus

Plumb Beach, Brooklyn, New York in USA is an important horseshoe crab breeding and nursery ground that has experienced substantial anthropogenic influence, including pollution, erosion and subsequent restoration. Since little is known about the relationship between sediment microbial communities and juvenile horseshoe crab survival, next generation sequencing was used to characterize and compare the sediment microbiome of three distinct areas of Plumb Beach:- a tidal creek with abundant juveniles, East Beach with moderate number of juveniles, and West Beach- a highly disturbed area where juvenile crabs are rarely seen. The microbiome of juvenile crab intestinal content (both dissected gut content and fecal flush content) from the tidal creek site was also examined. The results showed that in our 2017 survey, the overall dominant sediment orders at all beach sites were Vibrionales (30%), Flavobacteriales (22%) and Alteromonadales (21%). Although alpha diversity was similar among the three beach sites, Bray-Curtis distances assessed by Permanova revealed significant differences in Beta diversity, with a unique microbial assemblage found in the tidal creek. Both crab gut and fecal flush samples did not sequence well, showing low species diversity and very high variability. This study is the first to use next generation sequencing to characterize Plumb Beach sediment microbes and the first attempt to examine the gut microbiome of juvenile horseshoe crabs. This information will contribute to understanding the relationships between sediment microbial assemblages and juvenile crab populations within this important urban habitat

Spitzer Phase Curves of KELT-1b and the Signatures of Nightside Clouds in Thermal Phase Observations

We observed two full orbital phase curves of the transiting brown dwarf KELT-1b, at 3.6um and 4.5um, using the Spitzer Space Telescope. Combined with previous eclipse data from Beatty et al. (2014), we strongly detect KELT-1b's phase variation as a single sinusoid in both bands, with amplitudes of $964\pm36$ ppm at 3.6um and $979\pm54$ ppm at 4.5um, and confirm the secondary eclipse depths measured by Beatty et al. (2014). We also measure noticeable Eastward hotspot offsets of $28.4\pm3.5$ degrees at 3.6um and $18.6\pm5.2$ degrees at 4.5um. Both the day-night temperature contrasts and the hotspot offsets we measure are in line with the trends seen in hot Jupiters (e.g., Crossfield 2015), though we disagree with the recent suggestion of an offset trend by Zhang et al. (2018). Using an ensemble analysis of Spitzer phase curves, we argue that nightside clouds are playing a noticeable role in modulating the thermal emission from these objects, based on: 1) the lack of a clear trend in phase offsets with equilibrium temperature, 2) the sharp day-night transitions required to have non-negative intensity maps, which also resolves the inversion issues raised by Keating & Cowan (2017), 3) the fact that all the nightsides of these objects appear to be at roughly the same temperature of 1000K, while the dayside temperatures increase linearly with equilibrium temperature, and 4) the trajectories of these objects on a Spitzer color-magnitude diagram, which suggest colors only explainable via nightside clouds.Comment: AJ in press.
