Robotic mobile fulfillment system (RMFS) is a new type of parts-to-picker order picking system, where robots carry inventory pods to stationary pickers.Because of the difference in working mode, traditional storage assignment methods are not suitable for this new kind of picking system.This paper studies the storage assignment optimization of RMFS,
Assessing the distribution of chloroplast DNA (cpDNA) haplotype variation is useful for studying the phylogeography of angiosperms.In the last two decades the cpDNA phylogeography of white att nighthawk hotspot oaks in Europe has been extensively studied, mostly based on the PCR-RFLP technique.However, PCR-RFLPs have low mutation rates and are prim
In this paper, we proposed a contrast-enhanced homemade spectral domain optical coherence tomography (SD-OCT) method for monitoring of brain microcirculation.We used the polyethylene glycol (PEG)-ylated gold nanorods (GNRs) as a contrast-enhanced agent, obtained clearly 2D and 3D OCT images of blood vessels and dynamic changes of probes in mouse bl

Abstract To better describe the epidemiology of influenza at local level, the time course of pandemic influenza A (H1N1) 2009 in the city of Hong Kong was reconstructed from notification data after decomposition procedure and time series analysis.GIS (geographic information system) methodology was incorporated for assessing spatial variation.Betwee
