The Damaging Effects of Perceived Crocodile Tears for a Crier’s Image
Frontiers in Psychology, 2020 Emotional tears are uniquely human and play an essential role in the communication of distress in adults. Several studies have shown that individuals are more willing to offer emotional support and help a person in tears.

Calculations in the theory of tearing instability [PDF]
, 2018 Recent studies have suggested that the tearing instability may play a significant role in magnetic turbulence. In this work, we review the theory of the magnetohydrodynamic tearing instability in the general case of an arbitrary tearing parameter, which is relevant for applications in turbulence.

Proteomes, 2015 We produced a tear proteome of the genome mouse, C57BL/6, that contained 139 different protein identifications: 110 from a two-dimensional (2D) gel with subsequent trypsin digestion, 19 from a one-dimensional (1D) gel with subsequent trypsin digestion ...

Effect of guide field on three dimensional electron shear flow instabilities in collisionless magnetic reconnection [PDF]
, 2014 We examine the effect of an external guide field and current sheet thickness on the growth rates and nature of three dimensional unstable modes of an electron current sheet driven by electron shear flow. The growth rate of the fastest growing mode drops rapidly with current sheet thickness but increases slowly with the strength of the guide field.

Lipid polarity gradient formed by ω-hydroxy lipids in tear film prevents dry eye disease
eLife, 2020 Meibum lipids form a lipid layer on the outermost side of the tear film and function to prevent water evaporation and reduce surface tension. (O-Acyl)-ω-hydroxy fatty acids (OAHFAs), a subclass of these lipids, are thought to be involved in connecting ...

Kelvin-Helmholtz versus Tearing Instability: What Drives Turbulence in Stochastic Reconnection? [PDF]
, 2019 Over the last few years it became clear that turbulent magnetic reconnection and magnetized turbulence are inseparable. It was not only shown that reconnection is responsible for violating the frozen-in condition in turbulence, but also that stochastic reconnection in 3D generates turbulence by itself.

Bifurcations of the polycycle "tears of the heart": multiple numerical invariants [PDF]
arXiv, 2018 "Tears of the heart" is a hyperbolic polycycle formed by three separatrix connections of two saddles. It is met in generic 3-parameter families of planar vector fields. In [arXiv:1506.06797], it was discovered that generically, the bifurcation of a vector field with "tears of the heart" is structurally unstable.

On the tearing instability of highly elongated current sheets [PDF]
arXiv, 2018 Rigorous theories of the tearing instability are mathematically quite involving. Therefore, the present note aims to demonstrate how their main results can be reproduced by a simple qualitative analysis of the respective magnetohydrodynamic (MHD) equations.

Hall Resistive Tearing Mode: A Variational Formulation [PDF]
, 2008 A unified linear tearing-mode formulation is given incorporating both resistivity and Hall effects. A variational method is used that appears to be best suited to deal with the difficulties peculiar to the {\it triple-deck} structure associated with the Hall resistive tearing mode but also to lead to a convenient analytical dispersion relation for the ...
