High-Symmetry Polarization Domains in Low-Symmetry Ferroelectrics
, 2013 We present experimental evidence for hexagonal domain faceting in the ferroelectric polymer PVDF-TrFE films having the lower orthorhombic crystallographic symmetry. This effect can arise from purely electrostatic depolarizing forces.

Symmetries, Symmetry Breaking, Gauge Symmetries
, 2015 The concepts of symmetry, symmetry breaking and gauge symmetries are discussed, their operational meaning being displayed by the observables {\em and} the (physical) states. For infinitely extended systems the states fall into physically disjoint {\em phases} characterized by their behavior at infinity or boundary conditions, encoded in the ground ...

Novel pathogenic mtDNA variants in Chinese children with neurological mitochondrial disorders
Annals of Clinical and Translational Neurology, Volume 12, Issue 3, Page 586-601, March 2025.Abstract Objective Pathogenic variations in the mitochondrial genome are tightly linked to neurological mitochondrial disorders in children. However, the mutation spectrum of mitochondrial DNA (mtDNA) in the Chinese population remains incomplete. Therefore, the primary objective of our study was to comprehensively characterize pathogenic mtDNA variants

Action minimizing solutions of the Newtonian n-body problem: from homology to symmetry
, 2002 An action minimizing path between two given configurations, spatial or planar, of the $n$-body problem is always a true -- collision-free -- solution.

Symmetry and Surface Symmetry Energies in Finite Nuclei
, 2010 A study of properties of the symmetry energy of nuclei is presented based on density functional theory. Calculations for finite nuclei are given so that the study includes isospin dependent surface symmetry considerations as well as isospin independent ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Certain frontotemporal lobar degeneration subtypes, including TDP‐A and B, can either occur sporadically or in association with specific genetic mutations. It is uncertain whether syndromic or imaging features previously associated with these patient groups are subtype or genotype specific.

Partial Dynamical Symmetry as an Intermediate Symmetry Structure
, 2003 We introduce the notion of a partial dynamical symmetry for which a prescribed symmetry is neither exact nor completely broken. We survey the different types of partial dynamical symmetries and present empirical examples in each category.Comment: 10 ...

Claustrum Volume Is Reduced in Multiple Sclerosis and Predicts Disability
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The claustrum is a small, thin structure of predominantly gray matter with broad connectivity and enigmatic function. Little is known regarding the impact of claustrum pathology in multiple sclerosis (MS). Methods This study assessed whether claustrum volume was reduced in MS and whether reductions were associated with specific ...
