The genius of a good product designer is the ability to create an experience that delights the end user. The designer rarely invents the components; he or she makes them noticed. Smartphones, microfluidics, low-power devices, 1-way valves, optical sensing, multiplexed assays, frequency-shift keying, and lyophilization are not new technologies. A device that successfully orchestrates these instr...
Following reports in Korea of an increased risk of thyroid cancer among those living near nuclear power plants (NPPs) [1], there has been debate regarding the interpretation of the findings. One suggested explanation is the screening effect on thyroid cancer risk. The basic assumption of this argument is that the screening process increases the number of detected thyroid cancer cases in a popul...
BACKGROUND Multiple diagnostic algorithms for heart failure exist. However, it is unclear whether these algorithms are incorporated in the 'scripts' clinicians use in every day practice. Scripts are networks of organised knowledge that are acquired and accumulated during clinical training and are refined with each clinical encounter. This study was conducted to evaluate the scripts and threshol...
BACKGROUND The value of impulse oscillometry (IOS) for bronchial provocation testing is poorly defined. We investigated the positive threshold derived from the parameters and diagnostic power of IOS for asthma with the leukotriene D(4) bronchial provocation test. METHODS We enrolled 62 subjects with asthma and 21 healthy subjects. IOS was employed to perform the leukotriene D(4) bronchial pro...
after the soviet union dissolution, a chaotic period was begun in the russia. russia lost its glory and felt disgrace. the first group of elites came to power under yeltsin; they tried to re-define russia’s identity as a european country and build a foreign policy on this baseline. therefore russia tried to become closer with the west especially with the u.s. according to their view the sovie...
Objectives: The aim of the present study was to examine the factor structure, validity and reliability of the Modified Yale-Brown Obsessive-Compulsive Scale in a sample of Iranian students. Method: The method of this study was standardi-zation. After the translation of the original version of the mentioned Scale to Farsi and confirming it by three psychology and English language professors, the...

For the LCLS-II X-ray instruments, laser power meters are being developed as compact X-ray power diagnostics to operate at soft and tender X-ray photon energies. These diagnostics can be installed at various locations along an X-ray free-electron laser (FEL) beamline in order to monitor the transmission of X-ray optics along the beam path. In addition, the power meters will be used to determine...
Diagnostic codes within electronic health record systems can vary widely in accuracy. It has been noted that the number of instances of a particular diagnostic code monotonically increases with the accuracy of disease phenotype classification. As a growing number of health system databases become linked with genomic data, it is critically important to understand the effect of this misclassifica...
