Vector control remains the sole effective method to prevent dengue virus (DENV) transmission, although a vaccine for dengue has recently become available and testing of its efficacy and coverage is being performed in multiple places.Entomological surveillance is a key factor in alerting authorities to possible outbreaks, but until now natural DENV

Considering the problem of quantitative evaluation for qualitative survivability data and indexes of network information systems, the proposed method gives a multi-level survivability evaluation framework based on cloud model theory and AHP method.The algorithm builts a multi-level evaluation indexes system and compute Countdown Ornament the weight

Student behavior analysis can reflect students' learning situation in real time, which provides an important basis for optimizing classroom teaching strategies and improving teaching methods.It is an important task for smart classroom to explore how to use big data to detect and recognize students behavior.Traditional recognition methods have

The dynamic behavior of a discrete-time two-patch model with the Allee effect and nonlinear dispersal is studied in this paper.The Miscellaneous model consists of two patches connected by the dispersal of individuals.Each patch has its own carrying capacity and intraspecific competition, and the growth rate of one patch exhibits the Allee effect.Th

Blue honeysuckle (Lonicera caerulea) is a circumpolar species complex with representatives in Europe, Asia, and North America.Although honeysuckles (Lonicera spp.) from Eurasia have a history of invasiveness in North America, farmers and homeowners are interested in growing nonnative blue honeysuckle hybrids because of their edible blue fruits.To a
