The computation of axial charge with axial divergence

Nuclear Physics B, 1967
Abstract The consequences of a certain commutator between the axial charge and the axial divergence constructed from the strangeness-changing weak axial-vector current are investigated. A value for the F / D ratio in good agreement with the experiment is obtained. Finally a discussion of compatibility with the quark model is given.

Development of Axial Encoder to Measure Spindle Axial Motion

International Journal of Automation Technology, 2009
This paper deals with a newly developed axial encoder to measure spindle axial motion. The axial encoder was composed of a cylindrical rod with circular gratings and an optical encoder head. They were respectively mounted on the spindle nose and the worktable of a vertical milling machine.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Structural Performance of Columns with Glass Fiber-Reinforced Polymer Bars Under Axial Compression

Fibers
Corrosion continues to be a major challenge affecting the service life, safety and durability of steel-reinforced concrete (RC) structures. The deterioration of steel not only reduces structural capacity but also increases long-term maintenance costs. To

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Guías argentinas de práctica clínica, diagnóstico, evaluación y tratamiento en pacientes adultos con espondiloartritis axial

Revista Argentina de Reumatología
La espondiloartritis axial (EspAax) es una enfermedad crónica inflamatoria que incluye a la espondiloartritis radiográfica (EspAax-r) (anteriormente conocida como espondilitis anquilosante [EA]) y a la espondiloartritis axial no radiográfica (EspAax-nr)

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Axial Patterning in Hydra [PDF]

Cold Spring Harbor Perspectives in Biology, 2009
Morphogen gradients play an important role in pattern formation during early stages of embryonic development in many bilaterians. In an adult hydra, axial patterning processes are constantly active because of the tissue dynamics in the adult. These processes include an organizer region in the head, which continuously produces and transmits two signals ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
