in this article, we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators. considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...
BACKGROUND Data regarding the association between red cell distribution width (RDW) values and mortality in patients with stable coronary artery disease are scarce. We aimed to investigate the link between mortality and RDW in patients with stable coronary artery disease undergoing percutaneous coronary intervention (PCI). METHODS We analyzed 2550 consecutive patients with stable coronary art...
In this research, two joint evaluation rating methods (focus-on-attribute and drag-and-drop) and a separate evaluation rating method (focus-on-stimulus) are proposed for rating multiple visual stimuli with respect to multiple scales. All three interactive methods incorporate a real-time adjusting mechanism, allowing respondents to interactively adjust their ratings. Using the traditional paper-...
BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) parameters are markers of cerebral lesion in some diseases. In patients with acute subarachnoid hemorrhage (SAH), we investigated whether DTI parameters measured at <72 hours might be associated with delayed cerebral ischemia (DCI) and with poor functional outcome at 3 months (modified Rankin Scale score ≥3). METHODS DTI was performed in a...
BACKGROUND Therapeutic drug monitoring (TDM) is essential practice when dosing drugs with a narrow therapeutic index in order to achieve a plasma drug concentration within a narrow target range above the efficacy concentration but below the toxicity concentration. However, TDM with dose individualisation is challenging during a double-blind clinical trial with laboratory staff and investigators...
BACKGROUND Airway inflammation and airway hyperresponsiveness (AHR) are two characteristic features of asthma. Fractional exhaled nitric oxide (FENO) has shown good correlation with AHR in asthmatics. Less information is available about FENO as a marker of inflammation from work exposures. We thus examined the relation between FENO and AHR in lifeguards undergoing exposure to chloramines in ind...
Introduction: In medical diagnostic field, evaluation of diagnostic accuracy of biomarkers or tests has always been a matter of concern. In some situations, one biomarker alone may not be sufficiently sensitive and specific for prediction of a disease. However, combining multiple biomarkers may lead to better diagnostic. The aim of this study was to assess the performance of combination of bio...
Renovation and modernization can lead to changes in various fields, including material and immaterial values of the family. The process of cultural modernization has also brought about changes in the socio-cultural context of societies that have led to changes in family values. Therefore, the present study was aimed at the effect of cultural modernization on family values among high school stud...
Trust region methods are a class of important and efficient methods for solving unconstrained optimization problems. The efficiency of these methods strongly depends on the initial parameter, especially radius adjusting parameters. In this paper, we propose a new strategy for choosing the radius adjusting parameters. Numerical results from testing the new idea to solve a class of unconstrained ...
Identifying effects of actions (treatments) on outcome variables from observational data and causal assumptions is a fundamental problem in causal inference. This identification is made difficult by the presence of confounders which can be related to both treatment and outcome variables. Confounders are often handled, both in theory and in practice, by adjusting for covariates, in other words c...
