A survey of the mSUGRA/CMSSM parameter space is presented. The viable regions of the parameter space which satisfy standard experimental constraints are identified and discussed. These constraints include a 124-127 GeV mass for the lightest CP-even Higgs and the correct relic density for cold dark matter. The superpartner spectra corresponding to these regions fall within the well-known hyperbolic branch and are found to possess sub-TeV neutralinos and charginos, with mixed Bino/Higgsino LSP's with 200-800 GeV masses. In addition, the models possess ∼3-4 TeV gluino masses and heavy squarks and sleptons with masses mq, ml > mg. Spectra with a Higgs mass mh ≅125 GeV and a relic density 0.105 ≤ Ωχ h2 ≤ 0.123 are found to require EWFT at around the one-percent level, while those spectra with a much lower relic density require EWFT of only a few percent. Moreover, the spin-independent neutralino-proton direct detection cross-sections are found to be below or within the XENON100 2σ limit and should be experimentally accessible now or in the near future. Finally, it is pointed out that the supersymmetry breaking soft terms corresponding to these regions of the mSUGRA/CMSSM parameter space (m0 ∝ m1/2 with m0 2m1/2 2 and A0 =-m1/2) may be obtained from general flux-induced soft terms in Type IIB flux compactifications with D3 branes. © 2013 World Scientific Publishing Company.

Renewable and Sustainable Energy Reviews | Year: 2014

Energy security, environmental concerns, thermal comfort, and economic matters are driving factors for the development of research on reducing energy consumption and the associated greenhouse gas emissions in every sector of the economy. Building energy consumption estimation has become a key approach to achieve the goals on energy consumption and emissions reduction. Energy performance of building is complicated since it depends on multiple variables associated to the building characteristics, equipment and systems, weather, occupants, and sociological influences. This paper aims to provide an up-to-date review on the basics of building energy estimation. Regarding models, a classification for energy estimation models is proposed based on the different classifications found in the literature review. The paper focuses on models developed with whole building energy simulation software and their validation. This focus is justified because of the importance that whole building energy tools have gained on areas such as green building design, and analysis of energy conservation strategies and retrofits. Since a suitable weather file is a major component for reliably simulations, the section about weather data provides pertinent information. © 2013 Elsevier Ltd. Source

Advancing technology has made detecting fetal abnormalities in the first and second trimesters a reality. Few families are prepared for the difficult decisions that must be made if their unborn children are diagnosed with a life-limiting condition. Expectant parents are compelled to make decisions on the basis of limited options. A systematic review of the literature is presented with an aim to inform clinicians of parental experiences and outcomes after diagnosis of a fetal anomaly. The review focused on patients given a diagnosis for fetal anomalies for the 40-year period from 1970 to 2010 by using the key words such as fetal anomaly, congenital malformations, pregnancy termination, perinatal palliative care, and perinatal hospice. Regardless of the option taken, women often experienced intense grief reactions. Both giving birth to a child with a life-limiting condition and termination of pregnancy for fetal anomaly can be emotionally traumatic life events, both associated with psychological morbidity. Nonaggressive obstetric management, allowing natural birth without life-sustaining therapeutics, is an option for families. Couples presented with a coordinated perinatal palliative care model may opt to continue their pregnancy. Families who experienced perinatal hospice/palliative care report positive feedback, but more research is needed to explore the psychological outcomes of this choice.

An advanced investigation of the core-drilling method (CDM) for direct application in bridge assessment is conducted. In the CDM, a small hole is drilled into concrete and the displacements that result are measured and related to the in situ stress. Knowledge of the stress profile within the concrete of a girder would allow determination of the magnitude and location of force in its prestressing steel. The programme described in this paper and its companion paper had two objectives - to demonstrate the effectiveness of the CDM in determining concrete stresses when using small-diameter holes and to demonstrate feasibility, accuracy and appropriateness of the CDM for the assessment of prestressed concrete bridge girders and for determining the existing prestress in their tendons. The method had never been applied to a prestressed beam. After verifying the method in concrete slabs in part I of this work, the technique was used with 75 mm holes to investigate the stresses in a prestressed beam and to determine the force in its prestressing steel. The tendon forces determined by drilling any single hole using the CDM are accurate, with an average error of 58·5 kN and a relative error of 15·94%. They are also consistent, with a standard deviation in error of 75·2 kN. The tendon force in a prestressed concrete beam can be determined to within ±8% if three holes are drilled. Source

Background: More than 192 000 US women faced the challenge of living with breast cancer in 2009. Although exercise may help combat treatment-related symptoms, cancer-related fatigue has been identified as a potential barrier to engaging in physical activity. Self-efficacy has been proposed to mediate the impact of cancer-related fatigue on physical activity and subsequently improve quality of life (QOL). Objective: The purpose of this study was to determine the linkages among the concepts of an introductory model of fatigue related to cancer, self-efficacy for physical activity, physical activity, and QOL in women being treated for breast cancer. Interventions/Methods: Women currently receiving treatment for breast cancer were asked to complete 5 instruments: demographic profile, Piper Fatigue Scale, Physical Activity Assessment Inventory, Human Activity Profile, and McGill QOL Questionnaire. Structural equation modeling of the data was performed to determine the direct and indirect influences of study variables on QOL. Results: The model was tested based on responses of 73 participants. All paths between variables were significant. The model explained 53% of the variance in QOL scores, 28% of the variance in physical activity, and 31% of the variance in self-efficacy. Conclusions: Although fatigue is most commonly thought of as a physical problem requiring physical intervention, this study provides emerging evidence to suggest there may be potential interventions to improve self-efficacy that may mediate the effect of fatigue on QOL. Implications for Practice: Interventions to improve self-efficacy may contribute to increased physical activity and improved QOL in this population. Copyright © 2011 Lippincott Williams & Wilkins.
