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

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

Molecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Galilean relativity – Explained by means of the triangle solutions

Results 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.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

How to move an electromagnetic field? [PDF]

, 2011
As a first principle, it is the basic assumption of the standard relativistic formulation of classical electrodynamics (ED) that the physical laws describing the electromagnetic phenomena satisfy the relativity principle (RP).

PROPERTIES AND COMPUTER SIMULATION OF ELECTROMAGNETIC FIELD UNIFORM TRAFFIC CHARGED PARTICLE.

Ìнформаційні технології в освіті, 2010
In the article described the method of teaching electrodynamics, which is based on considerably fewer independent source principles (Coulomb's law, the principle of relativity and the principle of superposition).

Is the Basic Structure of the Universe Simple?

Axioms
Can our extremely complicated world be explained, starting from simple conditions and laws? Such questions easily become metaphysical, but at the same time they have historically served science well by promoting new and fruitful ideas.

A relativistic theory of the field II: Hamilton's principle and Bianchi's identities

Revista de Investigación de Física, 2021

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
