CONTEXT The number of metastatic lymph nodes (LNs) and the ratio of metastatic LN (LR) have been reported as predictors of recurrence in papillary thyroid carcinoma (PTC), while the role of LR or the number of metastatic LNs on the clinical response remains unclear. OBJECTIVE We aimed to compare the prognostic value of LR and the number of metastatic LNs on clinical response in PTC. DESIGN/...

In crisp production inventory problem, let q, a, b, d, R and r be the quantity produced per cycle, the holding cost, production cost, production quantity per day, the total demand quantity and the demand quantity per day, respectively. We consider three fuzzification methods. Firstly, we fuzzify q, a, b, d, R and r to triangular fuzzy numbers. Secondly, we fuzzify d and r to triangular fuzzy nu...

During a critical period of postnatal age sensory experience has a profound effect on maturation of visual cortical wiring. Electrophysiological evidence is indicating a substantial effect of visual deprivation on the visual cortical response properties. In this study we evaluated effect of light deprivation during a limited time of postnatal age on two aspects of spatial (working and reference...

the main aim of this paper intends to discuss the solution of fuzzy sylvester matrix equation

The objective of this study was to describe changes in genetic diversity in a colony of dog guides since its founding. Two breeds, German Shepherds (GS) and Labrador Retrievers (LR), were evaluated. Data were pedigrees of 4,699 GS and 3,573 LR dogs bred for use as guides by The Seeing Eye, Inc., Morristown, NJ. Rapid increases in average pairwise numerator relationships occurred in both breeds,...

firstly, in this paper, we apply the fuzzy restricted variation method to achieve an analytical and approximate unsymmetrical fuzzy solution for fully fuzzy quadratic equation. in this application, after finding the real root of 1-cut of $tilde{a}tilde{x}^{2}+tilde{b}tilde{x}+tilde{c}=tilde{d}$, initial guess is always chosen with possible unknown parameters that leads to highly accurate soluti...
