Warm inflation in Weyl geometric gravity
European Physical Journal C: Particles and FieldsWe investigate the warm inflationary scenario in Weyl geometric gravity theory, in which the action is constructed by adding matter to the simplest conformally invariant gravitational action in Weyl geometry.

European Physical Journal C: Particles and Fields, 2017 In the present work, we study the consequences of considering a new family of single-field inflation models, called power-law plateau inflation, in the warm inflation framework.

Breaking point: Identifying the factors that predict suspension from school
British Educational Research Journal, EarlyView.Abstract School suspensions are associated with adverse educational and psychosocial outcomes, yet little is known about how structural disadvantage, relational factors, health behaviours, well‐being indicators and school‐level factors jointly predict suspension risk in England.

Warm inflation solution to the eta problem [PDF]
Proceedings of International Workshop on Astroparticle and High Energy Physics — PoS(AHEP2003), 2003 Warm inflationary dynamics is shown to satisfy both the slow-roll and density perturbation constraints for $m_ϕ \gg H$ or equivalently $η\gg 1$ and for inflaton field amplitudes much below the Planck scale, $ < m_{pl}$. I start by reviewing the two types of inflation dynamics, isentropic or cold inflation and nonisentropic or warm inflation.

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.

, 2010 We propose a warm inflationary model in the context of relativistic D-brane inflation in a warped throat, which has Dirac-Born-Infeld (DBI) kinetic term and is coupled to radiation through a dissipation term. The perturbation freezes at the sound horizon and the power spectrum is determined by a combination of the dissipative parameter and the sound ...

Business Strategy and the Environment, EarlyView.ABSTRACT The aim of this study is to examine the impact of corruption control, as a public institutional mechanism, on hazardous waste emissions of private sector entities. We also examine the extent to which Agenda 2030 moderates the relationship. We analyse data from the top 500 global companies.

Business Strategy and the Environment, EarlyView.ABSTRACT Circular supply chain management (CSCM) practices are seen as a solution for addressing society's many significant environmental challenges. Although existing studies recognise the importance of reverse engineering in combating poverty, there is limited knowledge about its effectiveness in shaping CSCM practices to address climate change and ...

On the consistency of tachyon warm inflation with viscous pressure
Physics Letters B, 2015 We obtain conditions for the existence of an attractor in the system of equations describing a tachyon warm inflationary model with bulk viscosity taken into account. When these conditions are met the evolution approaches slow-roll regime. We present the

Business Strategy and the Environment, EarlyView.ABSTRACT Firms are increasingly looking into carbon dioxide removal (CDR), a set of options to take past emissions of greenhouse gases out of the atmosphere. Often two basic categories of CDR are distinguished: nature‐based solutions, such as planting trees or restoring wetlands, and technology‐based solutions, such as various forms of carbon capture ...
