Fabric on fabric: A conductive fabric‐based wearable coil using cutting plotter for MRI at 3T
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose Wearable coils fabricated using conductive threads have high resistance that limits SNR. The purpose of this work is to demonstrate the utility of conductive fabric as a coil conductor that can be fabricated using a cutting plotter.

Bifurcations and chaos in a discrete SI epidemic model with fractional order
Advances in Difference Equations, 2018 In this study, a new discrete SI epidemic model is proposed and established from SI fractional-order epidemic model. The existence conditions, the stability of the equilibrium points and the occurrence of bifurcation are analyzed.

Coronary Artery Blood Flow Imaging Using 3D Flow MRI
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.

Stability and Cycles in a Cobweb Model with Heterogeneous Expectations [PDF]
We investigate the dynamics of a cobweb model with heterogeneous beliefs, generalizing the example of Brock and Hommes (1997). We examine situations where the agents form expectations by using either rational expectations, or a type of adaptive ...

Mapping British Latinx Writing
Bulletin of Latin American Research, EarlyView.There are an estimated quarter of a million Latin Americans living in the UK, yet they remain outside the British national imaginary. This invisibility has historically extended to the literary scene and publishing industry, with only very few British‐based Latin American and Latinx writers gaining any exposure.
