The critical role of teacher educators in promoting socially just mathematics teaching

British Educational Research Journal, EarlyView.
Abstract This paper focuses on the enablers and constraints that shape mathematics teacher educators' agency in addressing social justice issues within their practice and how these can be harnessed or overcome. Given the potential impact of teacher educators on the student/practising teachers they work with, and consequently on the agency of classroom ...

Tidal disruption of asteroids by supermassive black holes [PDF]

, 2012
The compact radio source Sgr A* at the centre of our Galaxy harbours a super-massive black hole, and is therefore the nearest laboratory for testing the super-massive black hole astrophysics and environment. Since it is not an active galactic nucleus, it

Coalescence of Black Hole-Neutron Star Binaries

Living Reviews in Relativity, 2011
We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries. First, procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-

Compliant hydrogel cuff coating with real‐time pressure monitoring and antibiofilm capabilities for ventilator‐associated pneumonia prophylaxis

BMEMat, EarlyView.
A soft‐compliant hydrogel cuff coating combines real‐time pressure monitoring with intrinsic antibacterial activity for prophylaxis of ventilator‐associated pneumonia. A flexible pressure‐sensing patch is embedded in the coating to enable wireless dynamic monitoring of endotracheal cuff pressure through Bluetooth.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Effect of Irregular Particle Shape in Simulations of Tidal Disruption and Reaccumulation of Small Solar System Bodies

The Planetary Science Journal
Small solar system bodies subjected to planetary tides may be resurfaced, distorted, reshaped, split into binary or higher-multiple systems, or fragmented entirely. We investigate the effects of particle shape on numerical models of tidal deformation and

Addressing the Energy Trilemma: The Role of Entrepreneurship, Regulation, and Climate Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT Balancing energy security, energy equity, and environmental sustainability has become increasingly challenging as economies pursue low‐carbon growth amid climate risk and persistent disparities in access to modern energy. Although entrepreneurship is widely recognized as a driver of innovation, its role in addressing the energy trilemma ...

Binary disruption by massive black holes: hypervelocity stars, S stars, and tidal disruption events [PDF]

, 2012
journal articleWe examine whether disrupted binary stars can fuel black hole growth. In this mechanism, tidal disruption produces a single hypervelocity star (HVS) ejected at high velocity and a former companion star bound to the black hole.

On the Papaloizou–Pringle instability in tidal disruption events [PDF]

, 2017
We demonstrate that the compact, thick disc formed in a tidal disruption event may be unstable to non-axisymmetric perturbations in the form of the Papaloizou–Pringle instability. We show this can lead to rapid redistribution of angular momentum that can

Tidal Disruption Events from Stripped Stars

The Astrophysical Journal Letters
Observations of tidal disruption events (TDEs) show signs of nitrogen enrichment reminiscent of other astrophysical sources such as active galactic nuclei and star-forming galaxies. Given that TDEs probe the gas from a single star, it is possible to test
