Superluminality in the Fierz--Pauli massive gravity [PDF]

, 2008
We study the propagation of helicity-1 gravitons in the Fierz--Pauli massive gravity in nearly Minkowski backgrounds. We show that, generically, there exist backgrounds consistent with field equations, in which the propagation is superluminal.

Defossilisation of the Energy Supply of a Chemical Site by Integration of a Carnot Battery

Chemie Ingenieur Technik, EarlyView.
This study presents the results of a techno‐economic analysis of CO2‐free energy supply concepts for electricity and heat for the defossilisation of a chemical park in Germany for the model years 2030 and 2045. The focus is on the integration of a Carnot battery with thermal energy storage, which enables the flexible use of green fuels and renewable ...

Holographic bulk viscosity: GPR vs EO [PDF]

, 2011
Recently Eling and Oz (EO) proposed a formula for the holographic bulk viscosity, in arXiv:1103.1657, derived from the null horizon focusing equation. This formula seems different from that obtained earlier by Gubser, Pufu and Rocha (GPR) in arXiv:0806 ...

Designing Governance for ESG: Incentive and Oversight Complementarities in Corporate Sustainability Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates how internal governance design supports credible ESG performance by distinguishing between Incentive and Oversight Architectures. Using 13,993 firm‐year observations of US nonfinancial firms from 2018 to 2024, we estimate fixed effects and two‐step system GMM models.

Designer Cytokine Hyper Interleukin 11 (H11) is a Megakaryopoietic Factor [PDF]

International Journal of Medical Sciences, 2013
Interleukin-11 (IL-11) displays megakaryopoietic activity. We constructed super-cytokine Hyper- IL11 (H11) by linking soluble IL-11 receptor α (sIL-11Rα) with IL-11, which directly targets β-receptor (gp130) signal transducing subunit. The effects of H11 on hematopoiesis with a focus on megakaryopoiesis were studied.
