This paper presents an HIV/AIDS model with ideological transfer in male susceptible individuals, and considers condoms and education as control measures. First, it gives the threshold R 0 of the model. Then it proves that the disease-free ...

Hardware data prefetching is a well-studied technique to bridge the processor-memory performance gap. Bit-pattern-based prefetchers are one of the most promising spatial data prefetchers that achieve substantial performance gains. In bit-pattern-based ...

Non-volatile Memory Express (NVMe) storage has the advantage of ultraperformance. It has gained widespread adoption within cloud data centers, and its significance is only growing. Despite its widespread use, it still faces numerous challenges, such as ...

• We study how to promote the dissemination of a certain knowledge between group members via random communication and @mention function discussion in aWeChat ...

Studying how to promote knowledge dissemination in a WeChat group is of great significance to organizational knowledge management in China. There are two different ways for group members disseminating a certain knowledge: just sharing ...

Influenza is one of the major public health problems, and contact between all age groups and the emergence of influenza vaccines have played a vital role in the spread of influenza. In this paper, a mixed cross-infection influenza ...

Foot-and-mouth disease (FMD) is an acute and highly contagious infectious disease of cloven-hoofed animals. In order to reveal the transmission dynamics and explore effective control measures of FMD, we formulate a diffusive FMD model with a fixed latent ...

Coronavirus disease (COVID-19) cases and COVID-19-related deaths have been increasing worldwide since the outbreak in 2019. Before the mass vaccination campaign for COVID-19, the main methods for COVID-19 control in China were mass testing and quarantine. ...

This paper proposes a new order relation for Pythagorean fuzzy numbers (PFNs) and applies to multi-attribute group decision making (MAGDM). The main contributions are outlined as five aspects: (1) the concepts of relative distance and information ...

• The definition of second-neighbor network on an arbitrary undirected network and relative definitions are given for the first time.

Traditional infectious diseases models on metapopulation networks focus on direct transportations (e.g., direct flights), ignoring the effect of indirect transportations. Based on global aviation network, we turn the problem of ...

“No technology, no finance” has been the consensus in banking industry. Under the background of financial technology (Fintech), how to select an appropriate technology company to cooperate for the banks has become a key. The technology ...

• A possibility degree algorithm is devised to rank a series of PLTSs.
• An ...

Community structures in complex networks play an important role in researching network function. Although there are various algorithms based on affinity or similarity, their drawbacks are obvious. They perform well in strong communities, but ...

This paper focuses on the modeling of a rumor spreading in heterogeneous networks. Using the probability generating function method and pair approximation method, the current research obtains nonlinear differential equations to describe the dynamics of ...

H7N9 virus in the environment plays a role in the dynamics of avian influenza A (H7N9). A nationwide poultry vaccination with H7N9 vaccine program was implemented in China in October of 2017. To analyze the effect of vaccination and environmental virus ...

For infectious diseases such as influenza and brucellosis, the susceptibility of a susceptible highly depends on the distance from each adjacent infectious individual. Such a propagation mechanism is often modeled by a nonlocal incidence with a kernel ...

This article describes how economic development has had a significant impact on the environment. County eco-environment coordinated development has contributed to regional coordinated development in China. A support vector machine SVM model was ...

This paper develops a Pythagorean fuzzy (PF) mathematical programming method to solve multi-attribute group decision-making problems under PF environments. The main work is summarized as four aspects: (1) Considering the fuzziness and hesitancy in ...

As a typical computer virus, a file virus can parasitize in executable files and infect other files when the host files are executed. Due to the strong similarity between computer viruses and their biological counterparts, in this paper we adapt the ...

Reactiondiffusion models with time delay have been widely applied in population biology as well as epidemiology. This type of models can possibly exhibit complex dynamical behaviors such as traveling wave, self-organized spatial pattern, or chaos. ...

The model considers the seasonal migration of bird and periodic decay rate of virus in environment.Both temperature cycle and closing and reopening markets can lead to the observed recurrence.Migratory birds have little or no effect on local epidemic ...

Numerous studies on marital issues have frequently resorted to statistical analysis or mathematical modeling on a well-mixed homogeneous population. However, such mathematical models have largely ignored the effects of heterogeneous contact pattern among ...
