In this paper, we consider a second order evolution equation in Banach space, which can model an elastic system with structural damping. New forms of the corresponding first are introduced, and their well-posed property is proved by means operator semigroup theory. We give sufficient conditions for analyticity exponential stability associated semigroups.
Tick-borne infectious diseases pose a serious health threat in certain regions of the world. Emerging caused by novel tick-borne pathogens have been reported that are causing particular concern. Several often coexist same foci, and single vector tick can transmit two or more at time, which greatly increases probability co-infection host animals humans lead to an epidemic disease. The lack epidemiological data information on specific clinical symptoms related with means it is not currently...
Abstract: An infantile hemangioma is a congenital benign tumor formed by the proliferation of vascular cells during embryonic stage. It more common in skin but can also occur mucous membranes, liver, brain and muscle. Hepatic appears to be tumor; however, it may lead poor outcomes because severe complications, such as high-output cardiac failure. The main treatment hepatic infants oral drugs, propranolol glucocorticoids, clinical response not always satisfactory. We describe rare case...
In this paper, we use a monotone iterative technique in the presence of lower and upper solutions to discuss existence mild second order evolution equation initial value problem an ordered Banach space, which can model elastic system with structural damping. Under condition noncompactness measure on nonlinearity, obtain extremal positive solutions. Moreover, some applications are given illustrate our theoretical results.

A system of four coupled ordinary differential equations is considered, which are through migration both prey and predator model with logistic type growth. Combinedeffect quiescence providesa more realistic way modeling the complex dynamicalbehavior. The global stability Hopf bifurcation solutions investigated.
By means of the fixed point theory strict set contraction operators, we establish a new existence theorem on multiple positive solutions to singular boundary value problem for second‐order impulsive differential equations with periodic conditions in Banach space. Moreover, an application is given illustrate main result.

A total 96 Sprague-Dawley rats were randomly divided into PH group and PVS groups with mild, moderate, severe following PH. Hemodynamic parameters measured using high-frequency (5-12 MHz linear transducer), including pre-stenotic, stenotic, post-stenotic diameters (PVDpre, PVDs, PVDpost); pre-stenotic stenotic velocity (PVVpre, PVVs); hepatic artery peak systolic...
