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

open access: yesFEBS 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 ...

Charge-Preserving Operations in Quantum Batteries

open access: yesPRX Energy
Ergotropy provides a fundamental measure of the extractable work from a quantum system and, consequently, of the maximal useful energy, or charge, stored within it. Understanding how this quantity can be manipulated and transformed efficiently is crucial

War as Peace Enforcement. On the Issue of the Dialectics of War and Peace in Modern International Relations

open access: yesУправленческое консультирование
The problems of war and peace throughout the history of mankind remain the most discussed issues. Their solution is not only of purely theoretical interest, but also has an impact on the development of international law and relations between states ...

On invariants for measure preserving transformations [PDF]

open access: yesFundamenta Mathematicae, 2001
This paper applies the theory of definable equivalence relations developed in descriptive set theory to the study of the isomorphism relation among measure preserving transformations. Two invertible measure preserving transformations on the unit interval \(\sigma_1\) and \(\sigma_2\) are isomorphic if there exists another such transformation \(\pi ...

Maps on density operators preserving quantum f-divergences [PDF]

open access: yes, 2013
For an arbitrary strictly convex function f defined on the non-negative real line we determine the structure of all transformations on the set of density operators which preserve the quantum f ...

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

open access: yesFEBS 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 ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

CORPOREALITY IN THE AGE OF POSTHUMANISM: ANTAEISM AS A HUMAN PRACTICE OF ROOTEDNESS

open access: yesОсвітній дискурс
Relevance of the research. The beginning of the twenty-first century has been marked by radical transformations in the modes of human existence driven by the accelerated development of technologies, including bioengineering and genetic engineering. These

Decay of correlations in a chaotic measure-preserving transformation [PDF]

open access: yesPhysica D: Nonlinear Phenomena, 1983
Abstract For a chaotic, area-preserving map on the torus, we study the decay of correlations in detail. Taking as observables the square-integrable functions, we find examples of decay rates which are algebraic, exponential, and faster than exponential. For correlations that decay exponentially the rate is sensitive to the choice of function.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
