Synchronous symmetry breaking in neurons with different neurite counts. [PDF]
PLoS ONE, 2013 As neurons develop, several immature processes (i.e., neurites) grow out of the cell body. Over time, each neuron breaks symmetry when only one of its neurites grows much longer than the rest, becoming an axon. This symmetry breaking is an important step

Symmetry Breaking in Biology [PDF]
Cold Spring Harbor Perspectives in Biology, 2009 Symmetry breaking is essential for cell movement, polarity, and developmental patterning. Amplification of initial asymmetry is key to the conserved mechanisms involved.

Spontaneously broken subsystem symmetries
Journal of High Energy Physics, 2022 We investigate the spontaneous breaking of subsystem symmetries directly in the context of continuum field theories by calculating the correlation function of charged operators. Our methods confirm the lack of spontaneous symmetry breaking in some of the

Hsp90: Breaking the Symmetry [PDF]
Molecular Cell, 2015 Hsp90 chaperones receive much attention due to their role in cancer and other pathological conditions, and a tremendous effort of many laboratories has contributed in the past decades to considerable progress in the understanding of their functions. Hsp90 chaperones exist as dimers and, with the help of cochaperones, promote the folding of numerous ...

Symmetry Breaking Soliton, Breather, and Lump Solutions of a Nonlocal Kadomtsev–Petviashvili System
Complexity, 2020 The Kadomtsev–Petviashvili equation is one of the well-studied models of nonlinear waves in dispersive media and in multicomponent plasmas. In this paper, the coupled Alice-Bob system of the Kadomtsev–Petviashvili equation is first constructed via the ...

Symmetries of Symmetry Breaking Constraints
, 2010 Symmetry is an important feature of many constraint programs. We show that any problem symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different symmetries pick out different solutions in each symmetry class. This simple but powerful idea can be used in a number of different ways.

Breaking Symmetry on Time [PDF]
Developmental Cell, 2007 The habenular nuclei are a conserved relay center of telencephalic function, and they display bilateral asymmetry in many vertebrates. How this asymmetry is constructed in response to local lateralized cues remains poorly understood. A paper by Aizawa et al.

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 ...

ON THE SYMMETRY BREAKING PHENOMENON [PDF]
International Journal of Geometric Methods in Modern Physics, 2006 We investigate the problem of symmetry breaking in the framework of dynamical systems with symmetry on a smooth manifold. Two cases will be analyzed: general and Hamiltonian dynamical systems. We give sufficient conditions for symmetry breaking in both cases.
