Astrophysical S factor for the radiative capture 12N(p,gamma)13O determined from the 14N(12N,13O)13C proton transfer reaction

The cross section of the radiative proton capture reaction on the drip line nucleus 12N was investigated using the Asymptotic Normalization Coefficient (ANC) method. We have used the 14N(12N,13O)13C proton transfer reaction at 12 MeV/nucleon to extract the ANC for 13O -> 12N + p and calculate from it the direct component of the astrophysical S factor of the 12N(p,gamma)13O reaction. The optical potentials used and the DWBA analysis of the proton transfer reaction are discussed. For the entrance channel, the optical potential was inferred from an elastic scattering measurement carried out at the same time with the transfer measurement. From the transfer, we determined the square of the ANC, C^2(13Og.s.) = 2.53 +/- 0.30 fm-1, and hence a value of 0.33(4) keVb was obtained for the direct astrophysical S factor at zero energy. Constructive interference at low energies between the direct and resonant captures leads to an enhancement of Stotal(0) = 0.42(5) keVb. The 12N(p,gamma)13O reaction was investigated in relation to the evolution of hydrogen-rich massive Population III stars, for the role that it may play in the hot pp-chain nuclear burning processes, possibly occurring in such objects.Comment: 15 pages, 10 figures, 3 tables submitted to Phys.

Prediction and measurement of high frequency radio frequencies in peninsular Malaysia and comparisons with the international reference ionosphere model

Prediction of High Frequency (HF) radio frequency is important in the planning and operation of HF radio system because of the highly variable ionospheric region. Therefore, there is a requirement to find reliable and accurate HF operating frequencies in the Malaysian environment. The main aim of this study was to observe and analyze the HF prediction and measurement in Peninsular Malaysia which was then compared to the IRI Model prediction. This study was carried out in the equatorial region and in the middle of solar cycle 24 which was in July and August of 2014. The HF prediction process involved two maximum usable frequency (MUF) models, and the predicted result, i.e., operating working frequency (OWF) was based on hourly monthly median values. The results show that the IRI Model overestimated MUF prediction at about 36% for July 2014 and 38% for August 2014. This indicates that the IRI Model is an inappropriate model to be used for prediction of HF operating frequency in the Malaysian region. Meanwhile, the OWF measurements were around the OWF prediction, and this indicates that the OWF measurements are in the range of the OWF prediction. Accordingly, the lower decile MUF, i.e., OWF is the right range for HF operating frequency

Do Stressed Women Have Abnormal Glucose Level?

Stress is a physical, mental and emotional response to a challenging event and is a normal part of everyone\u27s life. It has been linked to suppression of the immune system and could increase the risk of getting ill or alter the course of existing illness. Studies show that stress is associated with increased HBA1c, especially in females. Therefore the purpose of this study was to determine the prevalence of stress with abnormal glucose value among the women community. A cross-sectional study was conducted among 168 residents of Mukim Sg. Pelek, Sepang, Selangor. Participants were selected through a simple random sampling and were asked to answer questionnaires provided. The Depression, Stress and Anxiety (DASS-21) scale was used to determine the prevalence of stress and random blood sugar (RBS) for measurement of the glucose level. Data was analyzed using Statistical Package Social Sciences (SPSS) version 20 and Chi-square analyses for determining the association between variables. The study found that 58.3% of the stressed women in the community have abnormal blood glucose level, which indicated that the risk of getting diabetes is slightly high. This finding has important implication for designing strategic plans for intervention program on awareness towards coping with stress positively

Improved Gaussian-Bernoulli Restricted Boltzmann Machines for UAV-Ground Communication Systems

Unmanned aerial vehicle (UAV) is steadily growing as a promising technology for next-generation communication systems due to their appealing features such as wide coverage with high altitude, on-demand low-cost deployment, and fast responses. UAV communications are fundamentally different from the conventional terrestrial and satellite communications owing to the high mobility and the unique channel characteristics of air-ground links. However, obtaining effective channel state information (CSI) is challenging because of the dynamic propagation environment and variable transmission delay. In this paper, a deep learning (DL)-based CSI prediction framework is proposed to address channel aging problem by extracting the most discriminative features from the UAV wireless signals. Specifically, we develop a procedure of multiple Gaussian Bernoulli restricted Boltzmann machines (GBRBM) for dimension reduction and pre-training utilization incorporated with an autoencoder-based deep neural networks (DNNs). To evaluate the proposed approach, real data measurements from an UAV communicating with base-stations within a commercial cellular network are obtained and used for training and validation. Numerical results demonstrate that the proposed method is accurate in channel acquisition for various UAV flying scenarios and outperforms the conventional DNNs

The role of corporate governance on the effect of state ownership on audit findings at state-owned enterprises

This study aims to analyze the extent to which the mediating role of corporate governance on the influence of state ownership on audit findings issued by Audit Board of the Republic of Indonesia on State-Owned Enterprises in Indonesia. The study used a sample of 98 observations (firm-year) during the period of 2010-2014. The results indicate that directly in line with predictions, there is a positive influence of the degree of state ownership on audit findings, and it is found that the level of state ownership has an indirect and negative effect on the governance of state enterprises, resulting in a negative impact of corporate governance on the audit. The results of this study imply that in order to reduce the potential for audit findings, the steps that need to be taken by the government gradually are to reduce the state ownership portion of SOEs, especially by privatization through stock offerings on the capital market and encouraging the implementation good governance in SOEs.peer-reviewe

Extracorporeal membrane oxygenation simulation-based training: methods, drawbacks and a novel solution

Introduction: Patients under the error-prone and complication-burdened extracorporeal membrane oxygenation (ECMO) are looked after by a highly trained, multidisciplinary team. Simulation-based training (SBT) affords ECMO centers the opportunity to equip practitioners with the technical dexterity required to manage emergencies. The aim of this article is to review ECMO SBT activities and technology followed by a novel solution to current challenges. ECMO simulation: The commonly-used simulation approach is easy-to-build as it requires a functioning ECMO machine and an altered circuit. Complications are simulated through manual circuit manipulations. However, scenario diversity is limited and often lacks physiological and/or mechanical authenticity. It is also expensive to continuously operate due to the consumption of highly specialized equipment. Technological aid: Commercial extensions can be added to enable remote control and to automate circuit manipulation, but do not improve on the realism or cost-effectiveness. A modular ECMO simulator: To address those drawbacks, we are developing a standalone modular ECMO simulator that employs affordable technology for high-fidelity simulation.Peer reviewe
