High-Tc via electron polar coupling: relation to low-Tc superconductivity and to chiral symmetry in particle physics

, 2001
Directional coupling of Thornber-Feynman polarization with the high-Tc ARPES distribution specifies the optimum flatband pseudogap \Delta and mobile localized quasiparticle.

Marked Directional Skull Asymmetry in the Araucan Horse [PDF]

VCOT Open, 2020
Abstract Background Deviations from the perfect symmetry of normally bilateral symmetrical characters occur during individual development due to the influence of multiple factors. Fluctuating asymmetry (FA) is the random developmental variation of a trait (or character) that is perfectly symmetrical, on average, across a population ...

Geometric Morphometric Analysis of Adult and Juvenile Turtle Shells: Directional Asymmetry and Fluctuating Asymmetry

Diversity
Bilateral symmetry is quite common in animals, but in some cases, asymmetry can be altered by hereditary or developmental processes. Symmetry may be preserved, or asymmetry may increase as the developmental stages progress.

Tracing the development and lifespan change of population-level structural asymmetry in the cerebral cortex

eLife, 2023
Cortical asymmetry is a ubiquitous feature of brain organization that is subtly altered in some neurodevelopmental disorders, yet we lack knowledge of how its development proceeds across life in health.

Filopodia-based contact stimulation of cell migration drives tissue morphogenesis

Nature Communications, 2021
Contact stimulation of migration drives tissue morphogenesis. Here the authors report that filopodia-based contact-dependent asymmetry of cell–matrix adhesion drives directional movement, whereas contractile actin cables contribute to the integrity of ...

Pearson's random walk in the space of the CMB phases: evidence for parity asymmetry

, 2011
The temperature fluctuations of the Cosmic Microwave Background (CMB) are supposed to be distributed randomly in both magnitude and phase, following to the simplest model of inflation.

Is the CMB asymmetry due to the kinematic dipole?

, 2012
Parity violation found in the Cosmic Microwave Background (CMB) radiation is a crucial clue for the non-standard cosmological model or the possible contamination of various foreground residuals and/or calibration of the CMB data sets.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Turbulent Cascade Direction and Lagrangian Time-Asymmetry [PDF]

Journal of Nonlinear Science, 2018
We establish Lagrangian formulae for energy conservation anomalies involving the discrepancy between short-time two-particle dispersion forward and backward in time. These results are facilitated by a rigorous version of the Ott-Mann-Gaw dzki relation, sometimes described as a "Lagrangian analogue of the 4/5ths law".
