Quantum Gravity as a Broken Symmetry Phase of a BF Theory

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
We explain how General Relativity with a cosmological constant arises as a broken symmetry phase of a BF theory. In particular we show how to treat de Sitter and anti-de Sitter cases simultaneously.

Gravitational radiation of a spherically symmetric source in f(R)-gravitation

open access: yesEuropean Physical Journal C: Particles and Fields
It is shown that Birkhoff’s theorem for the general theory of relativity is overcome in the f(R)-theory of gravitation. That means, the f(R)-theory of gravitation, unlike Einstein’s general theory of relativity, does not forbid gravitational radiation ...

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

open access: yesMolecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Galilean relativity – Explained by means of the triangle solutions

open access: yesResults in Physics
This paper presents a novel approach to understanding relativity through the lens of the triangle solutions. Triangle solutions will serve as a mathematical model for relativity.

Unruh effect of nonlocal field theories with a minimal length

open access: yesPhysics Letters B, 2018
The nonlocal field theory commonly requires a minimal length, and so it appears to formulate the nonlocal theory in terms of the doubly special relativity which makes the speed of light and the minimal length invariant simultaneously. We set up a generic

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Einstein e la sindrome ionica. Oltre la relatività generale, la ricerca di una teoria unitaria di campo continuo [PDF]

open access: yesS&F_scienzaefilosofia.it, 2016
Einstein and the ionic Syndrome. Searching for a unified Theory of continuum Field beyond the general Relativity In Physics and Reality (1936), Albert Einstein wrote about his General Theory of Relativity: “It is similar to a building, one wing of which

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

open access: yesMolecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.
