On the formal statement of the special principle of relativity [PDF]
The aim of the paper is to develop a proper mathematical formalism which can help to clarify the necessary conceptual plugins to the special principle of relativity and leads to a deeper understanding of the principle in its widest ...

Quantum Gravity: Motivations and Alternatives [PDF]
The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity.

Underdetermination in classic and modern tests of general relativity
AbstractCanonically, ‘classic’ tests of general relativity (GR) include perihelion precession, the bending of light around stars, and gravitational redshift; ‘modern’ tests have to do with, inter alia, relativistic time delay, equivalence principle tests, gravitational lensing, strong field gravity, and gravitational waves.

Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

A logic road from special to general relativity [PDF]
We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we ``derive'' an axiom system of general relativity in two natural steps.

On the Status of the Geodesic Principle in Newtonian and Relativistic Physics [PDF]
A theorem due to Bob Geroch and Pong Soo Jang ["Motion of a Body in General Relativity." Journal of Mathematical Physics 16(1), (1975)] provides a sense in which the geodesic principle has the status of a theorem in General Relativity (GR).

A classical Bousso bound for higher derivative corrections to general relativity
Focussing on theories for which the higher derivative terms are considered as small corrections in the Lagrangian to Einstein’s two-derivative theory of general relativity (GR), we prove the classical version of the covariant entropy bound (also known as

Wormholes and holography: an introduction
Wormholes are intriguing classical solutions in General Relativity, that have fascinated theoretical physicists for decades. In recent years, especially in Holography, gravitational Wormhole geometries have found a new life in many theoretical ideas ...

Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).
