3D model retrieval is becoming a hot research topic due to its wide applications such as computer-aided design, digital entertainment, and virtual reality.For this challenging task, feature learning and similarity measure are two critical problems.However, existing approaches usually learn discriminative visual features and develop a complex graph
A national HIV/AIDS and malaria parasitological survey was carried out in Tanzania in 2007-2008.In this study the parasitological data were analyzed: i) to identify climatic/environmental, socio-economic and interventions factors associated with child malaria risk and CAL/ MAG BLUEBERRY ii) to produce a contemporary, high spatial resolution parasit
CO2 Serves as one of the fundamental regulators of cerebral blood flow.It is widely considered that this regulation occurs through pCO2-driven changes in pH of the cerebral spinal fluid, with elevated and lowered pH causing direct relaxation and contraction of the smooth muscle, respectively.However, some findings also suggest that pCO2 acts indepe
In this paper, we consider a Beddington-DeAngelis predator-prey system with stage structure for predator and time delay incorporating prey refuge.By analyzing the characteristic equations, we study the local stability of Course a pied - Enfant - Chaussures - Trail the equilibrium of the system.Using the delay as a bifurcation parameter, the model u
