Introduction of database Olfaction is one of the oldest chemosensory systems in chordates, playing crucial roles in their foraging, predator evasion, social communication, mating and parental care (Guo et al., 2023; Li and Liberles, 2015; Liberles,2014). The initial step of olfaction is the binding and activation of olfactory receptors (ORs) by odorants in a combinatorial way (Malnic et al., 1999).

Dear editor,Depicting superior punctuality and originality,Weibo has become increasingly critical and influential in China for online information acquisition and sharing. However, very few research has studied Weibo to investigate event summarizing even though most of the published Weibos are event-driven. Besides, we observe that the existing methods are unsuitable for process-

This paper presents an efficient hardware prototype for network coding (NC). First, a packet synchronization mechanism is introduced to settle the problem of packet arriving mismatch between different incoming channels. Then a high-speed lookup-table-based circuit is designed to perform dot product over Galois Field, which forms the basic calculation unit of NC operation. Taking the speed advantage of FPGA hardware, this prototype is able to perform network coding operations within several hundred nanoseconds. Thus further studies and emulations on NC are able to be carried out upon this platform in the real network scenario.
