NONPARAMETRIC TEST FOR UBACT CLASS OF LIFE DISTRIBUTION BASED ON U-STATISTIC

Based on U-statistic, testing exponentially versus used better than aged in convex tail ordering (UBACT) class of life distribution is introduced for complete and cen-sored data. Convergence of the proposed statistic to the normal distribution is proved. Selected critical values are tabulated for sample sizes 5(5)80 for complete data, and (61)(10)(201) for censored data: The Pitman asymptotic relative e¢ ciency of the pro- posed tests to the other classes is studied. A numerical examples in medical science demonstrates practical application of the proposed test

Modeling Survival Distributions For Certain Real-World Applications Using Nonparametric Hypothesis Testing

By analyzing the failure behavior of the recorded survival data, we expect to analyze the different processing strategies or functionality of the tools or systems used in this nonparametric statistical test. It is anticipated that the test data would either behave exponentially or like the NBUE Property. If the survival results are NBUE, it is anticipated that the suggested treatment plan would be successful. Contrarily, As shown in the application section, if the data are exponential, the suggested treatment plan wont have any positive or negative consequences on patients. We evaluated the suggested tests efficacy and power for both complete and censored data, compared the outcomes with those of existing tests, and then applied the test to a variety of real-world data to demonstrate its validity

Energy Efficient Buildings in Smart Cities: Biomimicry Approach

Smart cities are those using technologies to make life easier for their citizens and enhancing the quality of life and urban service in order to reduce consumption, especially of energy. Biomimicry is one of the tools of the 21st century toachieve an emotional smart city that has its own spirit and identity. Biomimicryhas three main levels: organism, behaviour and ecosystem level, in terms of form generation, material selection,construction process, and function establishing.A subcategory of biomimicry is building skin which forms the entire exterior envelope of the building. It is the boundary through which buildings interact with the environment and the whole city. The aim of this paper isto discussbiomimicry as a tool to reduce energy consumption in cities through buildingskins. It also discusses concepts of smart cities. It provides an overviewof biomimicry as a tool of achieving a perfect biomimetic skin of buildings in smart cities. In addition it analysescase studies of energy conservationusing concepts of biomimicry. Finally it would conclude guidelines for biomimicry design of building skinsas a tool for reducing energy consumption in smart citie

A Framework for Arabic Concept-Level Sentiment Analysis using SenticNet

Arabic Sentiment analysis research field has been progressing in a slow pace compared to English and other languages. In addition to that most of the contributions are based on using supervised machine learning algorithms while comparing the performance of different classifiers with different selected stylistic and syntactic features. In this paper, we presented a novel framework for using the Concept-level sentiment analysis approach which classifies text based on their semantics rather than syntactic features. Moreover, we provided a lexicon dataset of around 69 k unique concepts that covers multi-domain reviews collected from the internet. We also tested the lexicon on a test sample from the dataset it was collected from and obtained an accuracy of 70%. The lexicon has been made publicly available for scientific purposes

Assessment of serum magnesium level in patients with bronchial asthma

AbstractBackgroundAsthma is one of the most common chronic diseases worldwide and has been increasing in prevalence over the last few decades. Magnesium ion has an inhibitory action on smooth muscle contraction, histamine release from mast cells and acetylcholine release from cholinergic nerve terminals. Magnesium has been shown to relax bronchial smooth muscles and influence the function of respiratory muscles. Hypomagnesemia have been associated with diminished respiratory muscle power.AimTo assess the serum Mg levels in bronchial asthma patients during stable and exacerbating clinical conditions.Subjects and methods60 Subjects were enrolled, 40 patients diagnosed as bronchial asthma and 20 healthy individuals as a control group. The asthmatic patients were divided into group (I) chronic stable bronchial asthma and group (II) acute exacerbation of bronchial asthma.ResultsSerum Mg levels were significantly lower in asthmatic patients compared with healthy controls and significantly lower in asthmatic patients during exacerbation compared with stable asthmatics. There was a positive correlation between serum Mg levels and each of FEV1/FVC ratio and FEV1.ConclusionHypomagnesemia was found in patients with chronic stable asthma and also in those with acute asthma exacerbation compared to control. Serum mg levels were significantly lower in asthmatic patients during exacerbations compared with stable asthmatics

Staphylococcus aureus nasal carriage among outpatients attending primary health care centers: a comparative study of two cities in Saudi Arabia and Egypt

AbstractEpidemiological and molecular data on community acquired methicillin resistant Staphylococcus aureus (CA-MRSA) are still scarce in both Egypt and Saudi Arabia. There is almost no data regarding methicillin resistant Staphylococcus aureus (MRSA) prevalence in both countries. This study was conducted to investigate the prevalence and molecular epidemiology of S. aureus and MRSA nasal carriage among outpatients attending primary health care centers in two big cities in both countries. A total of 206 nasal swabs were obtained, 103 swabs from each country. S. aureus isolates were characterized by antibiotic susceptibility, presence of mecA and PVL genes, SCCmec-typing and spa typing, the corresponding Multi locus sequence typing clonal complex was assigned for each spa type based on Ridom StaphType database. MRSA was detected in 32% of the Egyptian outpatients while it was found in 25% of the Saudi Arabian outpatients. All MRSA isolates belonged to SCCmec type V and IVa, where some isolates in Saudi Arabia remained nontypeable. Surprisingly PVL+ isolates were low in frequency: 15% of MRSA Egyptian isolates and 12% of MRSA isolates in Saudi Arabia. Two novel spa types were detected t11839 in Egypt, and t11841 in Saudi Arabia. We found 8 spa types among 20 isolates from Egypt, and 12 spa types out of 15 isolates from Saudi Arabia. Only two spa types t008 and t223 coexisted in both countries. Four clonal complexes (CC5, CC8, CC22, and CC80) were identified in both Egypt and Saudi Arabia. However, the data collected lacked a representation of isolates from different parts of each country as only one health center from each country was included, it still partially illustrates the CA-MRSA situation in both countries. In conclusion a set of control measures is required to prevent further increase in MRSA prevalence

Cryogenic Ion Trapping Systems with Surface-Electrode Traps

We present two simple cryogenic RF ion trap systems in which cryogenic temperatures and ultra high vacuum pressures can be reached in as little as 12 hours. The ion traps are operated either in a liquid helium bath cryostat or in a low vibration closed cycle cryostat. The fast turn around time and availability of buffer gas cooling made the systems ideal for testing surface-electrode ion traps. The vibration amplitude of the closed cycled cryostat was found to be below 106 nm. We evaluated the systems by loading surface-electrode ion traps with $^{88}$Sr$^+$ ions using laser ablation, which is compatible with the cryogenic environment. Using Doppler cooling we observed small ion crystals in which optically resolved ions have a trapped lifetime over 2500 minutes.Comment: 10 pages, 13 EPS figure
