A non-abelian analogue of DBI from $T \overline{T}$

SciPost Physics, 2020
The Dirac action describes the physics of the Nambu-Goldstone scalars found on branes. The Born-Infeld action defines a non-linear theory of electrodynamics. The combined Dirac-Born-Infeld (DBI) action describes the leading interactions supported on a

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

A Probe into the Evolution of Primordial Perturbations in the f(T) Gravity Framework with Chaplygin Gas

Particles
This work is focused on studying the cosmology of variable modified Chaplygin gas (VMCG) in the framework of exponential and logarithmic f(T) theory. The equation of state (EoS) for VMCG in exponential and logarithmic f(T) gravity shows quintom behavior.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

FEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

K. S. Stanislavski and the physical action [PDF]

Timisoara Physical Education and Rehabilitation Journal, 2017
Abstract We note that the physical action in the K. Stanislavski's system expresses the same meaning as the motor action in the field of Physic Education, consisting in accomplishing a task with the help of the skeletal muscles, mainly, of the physical exercise.

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Laser physics: Quantum controversy in action [PDF]

Reviews of Modern Physics, 1999
Laser physics is a subject whose roots go back to the very source of quantum thought, namely, blackbody radiation and the Planck distribution. But the road to the first maser device showing radiation amplification by stimulated emission was rocky indeed. Likewise, the struggle to produce the first laser was hampered by much false “wisdom.” Furthermore,

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

FEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...
