Published in 2017 at "Annalen der Physik"

DOI: 10.1002/andp.201600402

Abstract: Asymptotic state of an open quantum system may change substantially upon variations of system parameters. These changes can be often identified as bifurcation transitions in the classical mean-filed equations describing evolution of the relevant observables.… read more here.

Published in 2019 at "Asian Journal of Control"

DOI: 10.1002/asjc.1809

Abstract: In this paper, a new density‐dependent host–parasitoid model is proposed. The modification is based on density‐dependent factor by introducing Hassell growth function in host population. Moreover, the permanence of solutions, existence and uniqueness of positive… read more here.

Published in 2018 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.27654

Abstract: Bifurcations are particularly prone to errors in visual estimation of diameter stenosis. Dedicated bifurcation QCA software confirmed only 26–27% of side branch lesions visually estimated to have >50% DS. Validation against physiologic measures is necessary… read more here.

Published in 2020 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.29138

Abstract: Proximal to distal Y stenting technique is a modified bifurcation technique based on the original Y stenting technique described over 20 years ago. We use a bench top model to illustrate the steps of the technique,… read more here.

Published in 2020 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.29148

Abstract: Calcified coronary artery bifurcation lesions (CBL) remain a challenge for the interventional cardiologist. Evidence regarding treatment of CBL is minimal. Optimal plaque modification is the most important step prior to stent deployment. Provisional stenting is… read more here.

Published in 2021 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.29516

Abstract: Below the knee (BTK) peripheral arterial disease often presents with critical limb ischemia (CLI) clinically with involvement of more than one tibial vessels. Drug eluting stent (DES) technology for treatment of BTK disease has shown… read more here.

Published in 2022 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.30187

Abstract: We aimed to compare bare‐metal stents (BMS), durable‐polymer everolimus‐eluting stents (DP‐EES), and abluminal biodegradable‐polymer sirolimus‐eluting stents (ABP‐SES) in the bifurcation model setup. read more here.

Published in 2023 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.30537

Abstract: Stenting, initially with bare metal and subsequently with an antiproliferative drug coating, has undoubtedly been one of the major advances in the percutaneous treatment of obstructive coronary artery disease. All commercially available coronary stents have… read more here.
