Coordinate conditions and field equations for pure composite gravity [PDF]

open access: yesarXiv, 2021
Whenever an alternative theory of gravity is formulated in a background Minkowski space, the conditions characterizing admissible coordinate systems, in which the alternative theory of gravity may be applied, play an important role. We here propose Lorentz covariant coordinate conditions for the composite theory of pure gravity developed from the Yang ...

Scalarization of compact stars in the scalar-Gauss-Bonnet gravity

open access: yesJournal of High Energy Physics, 2019
We study scalarization of horizonless neutral compact reflecting stars. In our model, the scalar hair can be induced by the coupling of static scalar fields to the Gauss-Bonnet invariant.

Breaking the Recycling Bottleneck of Thermosets via Bio‐Tailoring Technology

open access: yesAdvanced Science, EarlyView.
Recyclable thermosets are achieved by using the Bio‐Tailoring technology. The Bio‐Tailoring technology effectively addresses the longstanding paradox surrounding the recyclable and reuse properties of thermosets, breaking the recycling bottleneck of thermosets.

Colorectal Cancer Cells–Derived Exosomal PIK3CA Mutation DNA Promotes Tumor Metastasis by Activating Fibroblast and Affecting Tumor Metastatic Microenvironment

open access: yesAdvanced Science, EarlyView.
PIK3CAH1047R DNA in colorectal cancer (CRC) cell‐derived exosomes can be delivered into recipient fibroblasts, where it is transcribed and translated, leading to the activation of fibroblasts into cancer‐associated fibroblasts, which secrete elevated levels of IL6. The simultaneous detection and targeting of PIK3CAH1047R mutation and IL6 may serve as a

Gravitational decoherence, alternative quantum theories and semiclassical gravity [PDF]

open access: yes, 2014
In this report we discuss three aspects: 1) Semiclassical gravity theory (SCG): 4 levels of theories describing the interaction of quantum matter with classical gravity.

Extension of Loop Quantum Gravity to Metric Theories beyond General Relativity

open access: yes, 2011
The successful background-independent quantization of Loop Quantum Gravity relies on the key observation that classical General Relativity can be cast into the connection-dynamical formalism with the structure group of SU(2).

Einstein gravity with generalized cosmological term from five-dimensional AdS-Maxwell-Chern-Simons gravity

open access: yesJournal of High Energy Physics
Some time ago, the standard geometric framework of Einstein gravity was extended by gauging the Maxwell algebra as well as the so called AdS-Maxwell algebra.

Radiation of scalar modes and the classical double copy

open access: yes, 2018
The double copy procedure relates gauge and gravity theories through color-kinematics replacements and holds for both scattering amplitudes and in classical contexts. Moreover, it has been shown that there is a web of theories whose scattering amplitudes
