A relativistic theory of the field II: Hamilton's principle and Bianchi's identities
Revista de Investigación de Física, 2021 As gravitation and electromagnetism are closely analogous long-range interactions, and the current formulation of gravitation is given in terms of geometry.

MACH PRINCIPLE AND PRINCIPLE OF RELATIVITY
Metafizika, 2020 The article considers the “many-faced” Mach principle and the principle of relativity, which are organically related due to the unity of nature, and provides a brief historical overview of the primary sources of these principles. Ernst Mach formulated his principle by criticizing Newtonian mechanics in his book [1] in 1896. A. Einstein, first using the

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Presentism in a World Denied Instantaneous Signals [PDF]
, 2011 The special theory of relativity (STR) is widely regarded as the primary threat to the otherwise intuitive presentist worldview. In particular, both the relativity and conventionality of simultaneity within STR appear to undermine presentism and support

Einstein’s Investigations of Galilean Covariant Electrodynamics prior to 1905 [PDF]
, 2004 Einstein learned from the magnet and conductor thought experiments how to use field transformation laws to extend the covariance to Maxwell’s electrodynamics. If he persisted in his use of this device, he would have found that the theory cleaves into two

FEBS Open Bio, EarlyView.The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Revisiting the Black Hole Entropy and the Information Paradox
Advances in High Energy Physics, 2018 The black hole information paradox and the black hole entropy are currently extensively researched. The consensus about the solution of the information paradox is not yet reached, and it is not yet clear what can we learn about quantum gravity from these

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...
