The Impact

The models of time-varying network have a profound impact on the study of virus spreading on the networks. On the basis of an activity-driven memory evolution model, a time-varying spatial memory model (TSM) is proposed. In the TSM model, the cumulative number of connections between nodes is recorded, and the spatiality of nodes is considered at the same time. Therefore, the active nodes tend to connect the nodes with high intimacy and close proximity. Then, the TSM model is applied to epidemic spreading, and the epidemic spreading on different models is compared. To verify the universality of the TSM model, this model is also applied to rumor spreading, and it is proved that it can also play a good inhibiting effect. We find that, in the TSM network, the introduction of spatiality and memory can slow down the propagation speed and narrow the propagation scope of disease or rumor, and memory is more important. We then explore the impact of different prevention and control methods on pandemic spreading to provide reference for COVID-19 management control and find when the activity of node is restricted, the spreading will be controlled. As floating population has been acknowledged as a key parameter that affects the situation of COVID-19 after work resumption, the factor of population mobility is introduced to calculate the interregional population interaction rate, and the time-varying interregional epidemic model is established. Finally, our results of infectious disease parameters based on daily cases are in good agreement with the real data, and the effectiveness of different control measures is evaluated.

Lines Of Evidence

Abstract According to Bastin et al.’s integrative memory model, familiarity may be attributed to both entity representations and relational representations. However, the model does not specify what triggers familiarity for relational representations. I argue that fluency is a key player in the attribution of familiarity regardless of the type of representation. Two lines of evidence are reviewed in support of my claim.

Summary: The Wechsler Memory Scale (WMS) is a laboratory-based memory test that has been criticized for its lack of ecological validity and for not testing long-term memory. A more recent memory test, which aims at testing everyday memory, is the Rivermead Behavioral Memory Test (RBMT); it tests prospective memory and other forms of memory not tapped by WMS. However, even this test does not capture all aspects of everyday memory problems often reported by adults. These problems are the object of the Everyday Memory Questionnaire (EMQ). This study aimed at identifying the relationships between these three memory tests. The differential effect of Alzheimer's disease (AD) on the above relationships was also studied. The sample consisted of 233 healthy adults (20 to 75+ years of age) and 39 AD patients (50 to 75 years of age). Confirmatory factor analysis revealed the following latent factors: Verbal Memory, Visual Reconstruction, Orientation, Message (action embedded in spatial context), Visual Recognition, Spatial Memory, New Learning/Association Forming, Prospective/Episodic Memory, and Metamemory. These first-order factors were further explained by two second-order factors: Semantic Memory and Coordination of Semantic and Visuo-Spatial Memory. This basic structure was preserved in the sample of AD patients, although AD patients performed less well on the WMS and the RBMT. Some interesting findings regarding semantic memory, face recognition, and metamemory in AD patients are also reported. Age, education, but no gender effects on memory performance were also detected.
