Nested sampling (NS) computes parameter posterior distributions and makes Bayesian model comparison computationally feasible. Its strengths are the unsupervised navigation of complex, potentially multi-modal posteriors until a well-defined termination point. A systematic literature review nested algorithms variants is presented. We focus on complete algorithms, including solutions to likelihood...

background and purpose: pneumocystis pneumonia, caused by pneumocystis jirovecii, is a fatal disease threatening patients with aids or immunosuppression. assessment of colonization in these patients is of great significance, since it can lead to severe pulmonary disorders. considering the scarcity of published reports on pneumocystis jirovecii isolates from patients in mashhad, iran, we aimed t...

We investigate the feasibility of trans-rectal optical tomography of the prostate using an endo-rectal near-infrared (NIR) applicator that is to be integrated with a trans-rectal ultrasound (TRUS) probe. Integration with TRUS ensures accurate endo-rectal positioning of the NIR applicator and the utility of using TRUS spatial prior information to guide NIR image reconstruction. The prostate NIR ...

Although organ-specific stem cells possess plasticity that permit differentiation along new lineages, production of endocrine pancreas and insulin-secreting beta cells from adult nonpancreatic stem cells has not been demonstrated. We present evidence that highly purified adult rat hepatic oval "stem" cells, which are capable of differentiation to hepatocytes and bile duct epithelium, can trans-...

This study was conducted to compare the social adjustment of the mothers with transsexual children with that of mothers with normal kids in order to find out the negative impacts of having a trans child on social adjustment of mothers. This research had a causal-comparative design. The statistical population of the study comprised mothers with trans children referred to Tehran Psychiatric Insti...

introduction: pleomorphic adenomas are tumors mostly originating from salivary glands. these lesions in the larynx are very rare. case report: we report a rare case of pleomorphic adenoma that originated from the mucosal lining, just above the glottic area at the level of the laryngeal ventricle in a 55-year-old female patient. the tumor could not be palpated easily but was observed in the ct s...

aim: regular physical activity has several physical, psychological and social benefits. however, it is a global health problem, especially among icu nurses. therefore, in order to improve nurses’ physical activity, it is required to determine the effective correlated factors. the aim of this study was to delineate predictive factors on the physical activity of icu nurses based on a trans-theore...

margarine contains a higher level of unsaturated and trans-fatty acids (tfa) than butter. the aim of this study was to investigate the physicochemical properties of these products in iranian market during storage. physicochemical analyses included fatty acid composition, peroxide and anisidine values, slip melting point (smp), color, chlorophyll content, solid fat content (sfc) and texture anal...
