In this paper, we study and compare the stability of trade policy arrangements in two different regulatory scenarios, one with without Preferential Trade Agreements (PTAs), i.e. current vs. modified WTO rules. Unlike existing literature, our paper considers an extensive choice set of trade constellations, containing both available PTAs, Customs Unions (CUs) and Free (FTAs), as well Multila...

We study a multi-group SAIRS-type epidemic model with vaccination. The role of asymptomatic and symptomatic infectious individuals is explicitly considered in the transmission pattern disease among groups which population divided. This natural extension homogeneous mixing SAIRS vaccination studied Ottaviano et. al (2021) to network communities. provide global stability analysis for model. deter...

riverbank erosion, land loss and associated sedimentation are river engineering and water resources management problems of global significance. the ability to predict riverbank stability on eroding rivers is the prerequisite of developing a channel width adjustment model and is essential for estimating riverbank erosion and associated sedimentation. in this research, a detailed model for stabil...

We consider a single-link multi-source network with FAST TCP sources. We adopt a continuous-time dynamic model for FAST TCP sources, and propose a static model to adequately describe the queuing delay dynamics at the link. The proposed model turns out to have a structure that reveals the time-varying network feedback delay, which allows us to analyze FAST TCP with due consideration of the time-...
