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 ...

An inductive theory of regional development

open access: yesPapers in Regional Science, 1993
Regional development tendencies in Western Europe in recent decades are analyzed. They show a mosaic-like pattern of dynamic and declining regions in all parts of Europe, while there is no uniform core/periphery polarization. On this basis, an inductive theory of regional development in economically advanced societies is constructed. It states that the

A Europe of the Regions vs. the Regions in Europe: reflections on regional engagement in Brussels. [PDF]

open access: yes, 2007
[From the introduction]. This paper addresses the somewhat paradoxical situation whereby on the one hand, the concept of a "Europe of the Regions" has largely been discredited and has generally fallen out of favour, whilst at the same time, the level of ...

The degree of predictability of earthquakes in several regions of China: statistical analysis of historical data

open access: yes, 2005
The stress release model, a stochastic version of the elastic-rebound theory, is applied to the historical earthquake data from three strong earthquake-prone regions of China, including North China, Southwest China, and the Taiwan seismic regions.

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 ...

Breakdown of field theory in near-horizon regions

open access: yesJournal of High Energy Physics
We discuss back-reaction in the semiclassical treatment of quantum fields near a black hole. When the state deviates significantly from Hartle-Hawking, simple energetic considerations of back-reaction give rise to a characteristic radial distance scale ∼

Modular parallel transport of multiple intervals in 1+1-dimensional free fermion theory

open access: yesJournal of High Energy Physics, 2023
Modular parallel transport is a generalization of Berry phases, applied to modular (entanglement) Hamiltonians. Here we initiate the study of modular parallel transport for disjoint field theory regions.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

A Dual Mind Approach to Understanding the Conscious Self and Its Treatment

open access: yesNeuroSci, 2021
In this paper I will address questions about will, agency, choice, consciousness, relevant brain regions, impacts of disorders, and their therapeutics, and I will do this by referring to my theory, Dual-brain Psychology, which posits that within most of ...
