In this paper, we investigate the dynamics of a discrete-time predator-prey system involving group defense.The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically.It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interior of R+2 by Cooker usi
Since nominal Cooker interest rate and nominal exchange rate are common for the Euro-zone (EZ) members, inflation differentials initiate real interest rate and real exchange rate divergences with further spill-over effects.The aim of the research is to investigate in which extent national price level, real interest rate and real exchange rate, co-m
Here we proposed a grape disease identification model based on improved YOLOXS (GFCD-YOLOXS) to achieve real-time detection of grape diseases in field conditions.We build a dataset of 11,056 grape disease images in 15 categories, based on 2566 original grape disease images provided by the State Key Laboratory of Plant Pest Biology data center after
Background: Periprosthetic joint infection (PJI) represents a devastating consequence of total joint arthroplasty (TJA) because of its high morbidity and its high impact on patient quality soccer packs of life.The lack of standardized preventive and treatment strategies is a major challenge for arthroplasty surgeons.The purpose of this article was
Since ancient times, locusts have been serious pests wreaking havoc on settled agriculture throughout much of the world.Numerous locust practices have been developed to control infestations.This has led to most commentaries portraying locust infestations only in a Hard Top Tools negative light while focusing on finding best management practices for
