BACKGROUND Early biomarkers are helpful for predicting clinical endpoints and for evaluating efficacy in clinical trials even if the biomarker cannot replace clinical outcome as a surrogate. The building and evaluation of an association model between biomarkers and clinical outcomes are two equally important concerns regarding the prediction of clinical outcome. This paper is to address both is...
OBJECTIVE To determine the value of positron emission tomography (PET) with contrast-enhanced computed tomography (CT) in assessing the need for neck dissection by retrospectively reviewing the pathology reports of patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (SCC). DESIGN Retrospective cohort study. SETTING Tertiary medical center. PATIENTS Se...
Purpose Parallel imaging allows for a considerable shortening of examination times. Limited data is available about the diagnostic accuracy of an accelerated knee MRI protocol based on parallel imaging evaluating all knee joint compartments in a large patient population compared to arthroscopy. Materials and Methods 162 consecutive patients with a knee MRI (1.5 T, Siemens Aera) and arthroscopy ...
BACKGROUND Combined testing of high-sensitivity cardiac troponin T (hs-cTnT) and copeptin at presentation provides a very high-although still imperfect-negative predictive value (NPV) for the early rule-out of acute myocardial infarction (AMI). We hypothesized that a second copeptin measurement at 1 h might further increase the NPV. METHODS In a prospective diagnostic multicenter study, we me...
The applicability of Net Present Value (NPV) in an investment project is becoming more and more popular in the field of engineering economics. The classical NPV methodology involves only the precise and accurate data of the investment project. In the present communication, we give a new mathematical model for NPV which uses the concept of intuitionistic fuzzy set theory. The proposed model is b...
The INFLU A.B-Quick and Directigen Flu A+B enzyme immunoassays were compared with direct immunofluorescence and cell culture for detection of influenza A and B viruses in a total of 255 patient specimens. Both assays identified 23 of 42 influenza A viruses (sensitivity, 54.8%; specificity, 100%; positive predictive value [PPV], 100%; negative predictive value [NPV], 91.8%). The INFLU A.B-Quick ...
A composite material comprising randomly distributed spherical particles of two different isotropic dielectric–magnetic materials is homogenized using the second–order strong– property–fluctuation theory in the long–wavelength approximation. Whereas neither of the two constituent materials by itself supports planewave propagation with negative phase velocity (NPV), the homogenized composite mat...
A decoupled fuzzy sliding-mode control for an aeroelastic system is derived. This aeroelastic dynamic system describes the nonlinear plunge and pitch motions of a wing section, using a single trailing-edge flap as the control input. The decoupled fuzzy sliding-mode control design method is proposed to simultaneously control both the plunge and pitch motions of the aeroelastic system. In this de...
