Abstract The dynamics of a diffusive predator-prey system with prey refuge and gestation FULL ZIP HOODIES delay is investigated in this paper.For a non-delay system, global stability, Turing instability and Hopf bifurcation are studied.For a delay system, time delay induced instability and Hopf bifurcation Pedal Pad are discussed.By the theory of n
Mastacembelus armatus is an important economic fish in China.Since males grow faster and larger than females, breeding monosex M.armatus has great value in the aquaculture industry.Cultivating YY fish is the key to producing genetically all male M.armatus.However, there have been no reports on production of fertile YY supermale, and the production
Contextualization: The species Hypericum perforatum is widely applied for the treatment of several diseases, mainly for depression.The plant is not native to Brazil, a country that has a high degree of the disease, being considered a public health problem.Knowledge gap: The establishment of the species in the country can provide greater economic an
As the number of internet users increases so does the number of malicious attacks using malware.The detection of malicious code is becoming critical, and the existing approaches need to be improved.Here, we propose a feature fusion method to combine the features extracted from pre-trained AlexNet and Inception-v3 deep neural networks with features
The accurate description of fracture distributions is a crucial prerequisite for fracturing design and the evaluation of fracturing effects in tight reservoirs.We employed a fractal L-system to establish a tree branch model and derived a planar simulation method to characterize the distribution of natural weak discontinuities in rock.Weak discontin
