    The Higgs Boson in the Periodic System of Elementary Particles

    It is proposed that the observed Higgs Boson at the LHC is the Standard Model Higgs boson that adopts the existence of the hidden lepton condensate. The hidden lepton is in the forbidden lepton family, outside of the three lepton families of the Standard Model. Being forbidden, a single hidden lepton cannot exist alone; so it must exist in the lepton condensate as a composite of μ’ and μ’± hidden leptons and their corresponding antileptons. The calculated average mass of the hidden lep-ton condensate is 128.8 GeV in good agreements with the observed 125 or 126 GeV. The masses of the hidden lepton con-densate and all elementary particles including leptons, quarks, and gauge bosons are derived from the periodic system of elementary particles. The calculated constituent masses are in good agreement with the observed values by using only four known constants: the number of the extra spatial dimensions in the eleven-dimensional membrane, the mass of electron, the mass of Z boson, and the fine structure constant

    Investigation of dynamic ground effect

    An experimental investigation of dynamic ground effect was conducted in the Univ. of Kansas wind tunnel using delta wings of 60, 70, 75 deg sweep; the XB-70 wing; and the F-104A wing. Both static and dynamic tests were made. Test data were compared to other test data, including dynamic flight test data of the XB-70 and F-104A. Limited flow visualization test were conducted. A significant dynamic effect was found for highly swept delta wings

    Reconstruction of respiratory patterns from electrocardiographic signals

    Presently there is lack of a reliable method for monitoring the respiratory cycles in ambulatory patients. Knowledge of respiratory pattern is useful in many clinical situations. With the ECG signal being the most frequently monitored biomedical signal, it is essential to extract the respiratory waveform from ordinary ECG tracings. Such a technique would permit reliable detection of respiratory efforts in healthy and diseased patients. Here, the authors present the result of a pilot study in which the ECG signals from lead II (LL+:RA-) and a modified chest lead I (V1+:LA-) were used to derive the respiration waveforms from the mean electrical axis of the heart. The ECG-derived respiratory patterns compared favorably with those obtained from airflow measurements

    Nicotine Poisoning Trends in Georgia

    Background: Nicotine is a toxic chemical that can cause adverse health effects. Nicotine poisoning can result from exposure to tobacco and other nicotine containing products. It can cause nausea, vomiting, abdominal pain, fever, dizziness, seizures, tachycardia, hypertension and edema. Nicotine poisoning can affect both adults and children. Methods: The Georgia Department of Public Health secured data from the Georgia Poison Center in order to analyze nicotinespecific poisoning calls, including e-cigarette poisoning calls. The data on tobacco/nicotine poisoning or exposure calls were collected from April 2009 to April 2015. The data on calls related to nicotine poisoning from e-cigarettes were collected from January 2011 to April 2015. Results: Approximately 1,513 tobacco/nicotine poisoning calls were received over 6 years. Of these, 1, 212 were related to exposures in children ages 0 to 5 years, including 853 from cigarette use, 474 from cigars and chewing tobacco, and 23 from Nicoderm, Nicorette and hookahs. Approximately, 164 calls on nicotine poisoning from e-cigarettes were received over 4 years. Of these, 93 were related to exposure in children ages 0 to 5 years. Ingestion accounted for 107 of the calls, while 22 had nicotine poisoning through dermal routes, 21 through inhalation/nasal routes and 12 through ocular routes. Conclusions: Nicotine poisoning is a major public health problem in Georgia; it is caused by tobacco products and electronic nicotine delivery systems. Adopting tobacco-free/smoke-free policies that include e-cigarettes in homes, workplaces and vehicles will prevent nicotine poisoning

    Distinguishing “mHealth” from Other Healthcare Services in a Developing Country: A Study from the Service Quality Perspective

    Get PDF
    Mobile phones’ exponential growth is fuelling the emergence of mobile health (mHealth), thus contributing to healthcare services’ innovative transformation in developing countries. mHealth’s ubiquitous personalised capabilities obviate the access barriers and dismal performance of conventional systems, therefore gaining popularity among patients. Researchers have focused on service quality―a vital element of service adoption―and sustainability. For mHealth to become a robust alternative, how patients perceive mHealth vis-à-vis conventional services must be understood. Comparative analysis studies between mHealth and conventional systems are scarce yet would contribute to theory and strengthen the antecedent phases to service quality, that is, design and operation. mHealth is a viable alternative for fulfiling the unmet goal of quality of life for all. Prompted by these insights, this study is the first attempt to discover the differentiating characteristics of mHealth. Patients’ perceptions were analyzed by multiple discriminant analysis, a classification technique. The findings show that, in distinguishing between healthcare services, mHealth is a favourable alternative: service differentiation occurs along the dimensions of ubiquity, information-quality, and value. The findings’ implications for theory and practice and future research guidelines are also discussed
