The alternative, interferometric synthetic aperture radar (InSAR), provides high spatial resolution but is limited by a low sensitivity to N-S motion. We study the active normal fault network of Western Türkiye, which is undergoing rapid N-S extension, using InSAR.

Methods: We compared the indications for admission during the first wave of the pandemic to a control period prior to the lockdown (November 9, 2019 to March 22, 2020).
The main purpose of this article is to analyze the bifurcation, chaotic behaviors, and solitary wave solutions of the fractional Twin-Core couplers with Kerr law non-linearity by using the planar dynamical system method. This equation has profound physical significance and application value in the areas of optics and optical communication. Firstly, the traveling wave transformation is applied to convert the beta-derivative Twin-Core couplers with Kerr law non-linearity into the ordinary differential equations.

From this queer environmentalist pun we birthed a new take on our relationship to the Earth amidst climate crises - and in doing so, we came out as ecolesbians. Ecolesbianism is a concept we co-created, bringing together queer ecologies, political lesbianism, ecofeminism, transecology, ecosexuality, and our own experiences.

Road crashes are a major public safety concern in Pakistan. Prior studies in Pakistan investigated the impact of different factors on road crashes but did not consider the temporal stability of crash data. This means that the recommendations based on these studies are not fully effective, as the impact of certain factors may change over time.
