Background: The increased resorption and the difficulty of the fat graft take following autologous fat transplantation procedure are associated with reduced fat tissue revascularization and increased apoptosis of adipose cells.We suppose that the lipofilling procedure induces an inflammatory environment within the fat graft mass, whose evolution in

Abstract Background Propensity scores are widely used to deal with confounding bias in medical research.An incorrectly specified propensity score model may lead to residual confounding bias; therefore it is essential to use diagnostics to assess propensity scores in a propensity score analysis.The current use of propensity score diagnostics in the

The double-layer charge can effectively improve the axial driving ability of explosives, which shows a considerable engineering application prospect in highly efficient damage warheads.Due to the complex wave structure produced by the overpressure detonation of a double-layer charge, a series of dynamic behaviors inside the shaped charge liner will

Poetry as a mode of philosophizing can reasonably be considered a failure when making the following moves: from the experientially particular to general content (by means of abstract thought); from ordinary pre-reflective thinking (a contingent thought someone happened to have) to philosophically rigorous thought (which is rationally grounded); fro

During recent years, Trojan viruses on Android systems have greatly evolved, and the frequent security breach of Android systems is rapidly becoming a great concern of contemporary cyber security.The study of Trojan virus detection on Android engine and the application of its outcome has become increasingly significant.A feature code detection algo
