Human Enteroviruses replicate in gastrointestinal tract and are excreted to the sewage system through feces, so isolation of Enteroviruses from sewage can be considered as a sensitive indicator for virus cirulation in society. They are originally given the name of Enteroviruses, but the inadequacy of this term became apparent when some Coxackie and Echoviruses were also found in acute respirato...
BACKGROUND Phase angle, determined by bioelectrical impedance analysis (BIA), detects changes in tissue electrical properties and has been found to be a prognostic indicator in several chronic conditions-such as HIV, liver cirrhosis, chronic obstructive pulmonary disease, and lung cancer-and in patients receiving dialysis. OBJECTIVE This study was conducted to investigate the prognostic role ...
BACKGROUND A frequent manifestation of advanced cancer patients is malnutrition, which is correlated with poor prognosis and high mortality. Bioelectrical impedance analysis (BIA) is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated BIA-derived phase angle as a prognostic indicator for survival in advanced cancer patients. ...
Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...
x-ray coronary angiography has been a gold standard in the clinical diagnosis and interventional treatment of coronary arterialdiseases for decades. in angiography, a sequence of images is obtained, a few of which are suitable for physician inspection. thispaper proposes an automatic algorithm for the extraction of one or more frames from an angiogram sequence, which is most suitablefor diagnos...
Solvent extraction–spectrophotometries based on ion association formation have been established for the improvement of the sensitivity for the determination of ionic compounds such as anionic and cationic surfactants using hydrophobic dye ions. For example, anionic surfactants were determined using Methylene Blue,1 Ethyl Violet,2 Co(III)-5-Cl-PADAP3 and Malachite Green.4 Bromocresol Green,5 2,6...
The climate in the Altai Mountains is determined by two major systems whose dominance has varied over time, leading to significant spatio-temporal changes temperature and precipitation during Holocene. This study aimed at reconstruction of local regional moisture conditions an alpine belt southern Mongolian Late It thereby contributes a more comprehensive understanding region’s palaeoclimate Ou...
The existence of the monopole condensation transition reported by Koci´c et al. [1] in non-compact, quenched QED is tested. No phase transition is found. This shows that divergence of the 'monopole susceptibility' introduced by Hands and Wensley [2] is not a reliable indicator of second order phase transitions. In view of these results I discuss claims [3] that the chiral phase transition seen ...
The present paper investigates the application of three-phase ZCZ sequence sets to AS-CDMA systems that use coded TPSK. First, we clarify possible three-phase ZCZ sequence sets and the features of these ZCZ sequence sets. Next, we clarify the structure of the periodic correlation function between sequences that belong to three-phase ZCZ sequence sets. Finally, we propose a method for constructi...
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
