A Complexity‐Based Approach to Migration Policy Change: The Case of the German Residence Act
Regulation &Governance, EarlyView.ABSTRACT This paper adapts and applies existing indicators to measure the complexity of German migration policy over time. Building on recent scholarship that conceptualizes migration policy as multidimensional, I adapt a measurement strategy from the EUPLEX Project to capture three key components of regulatory complexity: structural, linguistic, and ...

The Ricci flow and the early universe
Annals of Physics, 2023 A framework of quantum spacetime reference frame is proposed and reviewed, in which the quantum spacetime at the Gaussian approximation is deformed by the Ricci flow. At sufficient large scale, the Ricci flow not only smooths out local small irregularities making the universe a homogeneous and isotropic Friedmann-Robertson-Walker metric, but also ...

A note on the Cotton flow and the Ricci flow for three-manifolds, and the Hořava–Lifshitz gravity
European Physical Journal C: Particles and FieldsWe consider the more general geometrical flow in the space of metrics for three-manifolds that consists of a combination of two flows, the Cotton flow and the Ricci flow; by playing a fundamental role in the detailed balance principle of the four ...

Sedimentology, EarlyView.ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of proposed relationship between hyperglycaemia, gestational diabetes mellitus (GDM), active BCR‐related (ABR), RhoA and actin organization of feto‐placental arterial endothelial cells (fpEC). Hyperglycaemia upregulates ABR, which in turn increases RhoA activation.

The Journal of Physiology, EarlyView.Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Singularities of Connection Ricci Flow and Ricci Harmonic Flow
, 2013 In this paper, we study the singularities of two extended Ricci flow systems --- connection Ricci flow and Ricci harmonic flow using newly-defined curvature quantities. Specifically, we give the definition of three types of singularities and their corresponding singularity models, and then prove the convergence. In addition, for Ricci harmonic flow, we
