Modeling and Stability Analysis of the Dynamics of Malaria Disease Transmission with Some Control Strategies by Alemzewde Ayalew, Yezbalem Molla, Amsalu Woldegbreal

“…Moreover, the forward bifurcation phenomenon of the model system for R0=1 was analyzed by using center manifold theory. A sensitivity analysis of the basic reproduction number was performed to identify parameters that will cause to trigger the transmission of malaria disease and should be targeted by control strategies. …”

A New Evaluation Method for the Fracability of a Shale Reservoir Based on the Structural Properties by Haoyue Sui, Wei Gao, Ruilin Hu

“…Focused on the lack of structural factors included in the previous fracability evaluation methods, a new model for fracability evaluation based on the combination of the brittleness index, structural index, and fracture toughness was constructed using a linear elastic fracture theory. The model showed that good fracability not only included higher brittleness but also required less energy to produce cracks. …”

A Novel Spectrometer for Measuring Laser-Produced Plasma X-Ray in Inertial Confinement Fusion by Zhu Gang, Xiong Xian-cai, Zhong Xian-xin, Yang Yan

“…In order to diagnose laser-plasma distribution in space and evolution in time, an elliptical curved crystal spectrometer has been developed and applied to diagnose X-ray of laser-produced plasma in 0.2~2.46 nm region. According to the theory of Bragg diffraction, four kinds of crystal including LiF, PET, MiCa, and KAP were chosen as dispersive elements. …”

Older adults do not consistently overestimate their action opportunities across different settings by Isabel Bauer, Milena S. Gölz, Lisa Finkel, Maddalena Blasizzo, Sarah E. M. Stoll, Jennifer Randerath

“…We examined older adults’ (n = 40) judgment tendencies in four different tasks by use of a detection theory approach. The tasks’ setting differed in their boundaries’ proximity to the actor with either proximal (e.g., judging one’s hand fit into an opening) or distal boundaries (e.g., judging the reachability of a distant object). …”

A New Simple Epidemic Discrete-Time Model Describing the Dissemination of Information with Optimal Control Strategy by Hamza Boutayeb, Sara Bidah, Omar Zakary, Mostafa Rachik

“…We consider the possible interactions between individuals and information on the Internet, such as posts, images, and videos. The theory of control is used to show the effectiveness of our optimal control strategy in reducing the information amount and sharers and then decreases the dissemination of false information that can lead to annoying situations and unstable state in the society. …”

Deformation Failure Characteristics of Coal Body and Mining Induced Stress Evolution Law by Zhijie Wen, Guanglong Qu, Jinhao Wen, Yongkui Shi, Chuanyang Jia

“…All this indicates that the pore distribution of coal body with different compressed volume has fractal character; it appears to be the linear relationship between propagation range of internal stress field and compressed volume of coal body and nonlinear relationship between the range of outburst coal mass and the number of pores which is influenced by mining pressure. The results provide theory reference for the research on the range of mining-induced stress and broken coal wall.…”
