Spontaneous Ca2+ signals in the developing mammalian cochlea of live mice under different anaesthetic regimes

open access: yesExperimental Physiology, EarlyView.
Abstract The pre‐hearing mouse cochlea undergoes critical periods of spontaneous Ca2+‐dependent activity that spreads across non‐sensory supporting cells and inner hair cells (IHCs). These signals have been shown to regulate not only the refinement of neural circuits along the auditory pathway towards functional maturity, but also the maturation of the

The RhoA guanine exchange factor ABR: a glucose‐sensitive mediator of actin reorganization in feto‐placental arterial endothelial cells altered by gestational diabetes mellitus

open access: yesThe 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.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe 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.

Collapsing immortal Kähler-Ricci flows

open access: yesForum of Mathematics, Pi
We consider the Kähler-Ricci flow on compact Kähler manifolds with semiample canonical bundle and intermediate Kodaira dimension, and show that the flow collapses to a canonical metric on the base of the Iitaka fibration in the locally smooth topology ...

Generalized Sasakian Space-Forms with Beta-Kenmotsu Structure and Ricci Solitons [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
We explore the properties of almost Ricci solitons and the gradient Ricci solitons on generalized Sasakian-space-forms with beta-Kenmotsu structure. We consider almost Ricci solitons on generalized Sasakian-space-forms with beta-Kenmotsu structure when ...

Singularities of Connection Ricci Flow and Ricci Harmonic Flow

open access: yes, 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

Forman-Ricci Flow for Change Detection in Large Dynamic Data Sets

open access: yesAxioms, 2016
We present a viable geometric solution for the detection of dynamic effects in complex networks. Building on Forman’s discretization of the classical notion of Ricci curvature, we introduce a novel geometric method to characterize different types of real-
