Two propylene amine oxime (PnAO) complexes, 1, containing a 3-nitro-1,2,4-triazole and 2, containing two 3-nitro-1,2,4-triazoles, were synthesized and radiolabeled with (99m)Tc in high labeling yields. Cellular uptakes of (99m)Tc-1 and (99m)Tc-2 were tested using a S180 cells line. Under anoxic conditions, the cellular uptakes of (99m)Tc-1 and (99m)Tc-2 were 33.7 ± 0.2% and 35.0 ± 0.7% at 4 h, ...

OBJECTIVE The authors' goal was to determine whether FDG uptakes in various regions of the brain are different for early and late scanning time in positron emission tomography (PET). METHOD F-18 fluorodeoxyglucose (FDG) PET was performed on 15 healthy normal subjects to obtain early and late acquisition glucose metabolic images (30 and 60 min after FDG injection), respectively. The two sets o...

STUDY DESIGN Retrospective study. PURPOSE To estimate the usefulness of bone scan and magnetic resonance imaging (MRI) for the diagnosis of new fracture in osteoporotic vertebral fractures. OVERVIEW OF LITERATURE The diagnosis of new fractrure in osteoporotic vertebral fractures requires simple X-ray and supplementary studies. METHODS We analyzed 87 vertebrae in 44 patients, who diagnosed...

In this paper, we study the global dynamics of a chemostat model with a single nutrient and several competing species. Growth rates are not required to be proportional to food uptakes. Our approach is based on the construction of Lyapunov functions. The Lyapunov functions extend those used by Hsu [SIAM J. Appl. Math. (1978) 34:760-763] and by Wolkowicz and Lu [SIAM J. Appl. Math. (1992) 57:1019...

oral corrective feedback, according to many researchers’ points of view, plays a crucial role in facilitating and accelerating the process of the second language learning. the present study aims to identify persian learners’ error types, the teachers’ feedback types and learners’ uptakes; also it is aimed at determining the most and least frequent errors occurred on the basis of lyster and rant...

There has been an increased interest in data generation approaches to grammatical error correction (GEC) using pseudo data. However, these suffer from several issues that make them inconvenient for real-world deployment including a demand large amounts of training On the other hand, some errors based on rules may not necessarily require amount if GEC models can realize generalization. This stud...
