The threat of future global warming has generated a major interest in quantifying past climate variability on centennial and millennial time-scales.However, palaeoclimatological records are often noisy and arguments about past variability are only possible if they are based on reproducible features in several reliably dated datasets.Here we focus o
Objective: Fungiform papillae contain taste buds and play a critical role in mastication and the gustatory system.In this study, we report a series of sequential observations of organogenesis of fungiform papillae in miniature pigs, as well as changes in the expression of BMP2, BMP4, Wnt5a, Sox2, and Notch1 signaling pathway components.Design: In t
Contamination of agricultural products with heavy metals in soil and air is considered as serious threat to the quality and safety of these products.Cars and vehicles are among the major sources of heavy metals such as lead, iron and copper in the environment surrounding roads and highways.According to carcinogenic and destructive effects of these
The reader-to-reader collision in an RFID system is a challenging problem for communications technology.In order to model the interference between RFID readers, different interference models have been proposed, mainly based on two approaches: single and additive interference.The former only considers the interference from one reader within a certai
