Erratum: Good vibrations —Transition in drop generation from an immersed capillary tube

Drop formation in viscous flows at a vertical capillary tube

Drop formation at the tip of a vertical, circular capillary tube immersed in a second immiscible fluid is studied numerically for low-Reynolds-number flows using the boundary integral method. The evolution and breakup of the drop fluid is considered to assess the influences of the viscosity ratio l , the Bond number B, and the capillary number C for 10<l<10, 10<C<1, and 0.1<B<5. For very small ...

Good Vibrations

How and where the brain forms associations between sensation and action are crucial questions in the field of cognitive neuroscience. In this issue of Neuron, add to an already impressive body of work elucidating the neural mechanisms responsible for forming categorical decisions about vibrotactile stimuli that guide behavior. Here they show that single neurons in premotor cortex represent, rem...

Structured Polynomial Eigenvalue Problems: Good Vibrations from Good Linearizations

Many applications give rise to nonlinear eigenvalue problems with an underlying structured matrix polynomial. In this paper several useful classes of structured polynomial (e.g., palindromic, even, odd) are identified and the relationships between them explored. A special class of linearizations that reflect the structure of these polynomials, and therefore preserve symmetries in their spectra,...

Palindromic Polynomial Eigenvalue Problems: Good Vibrations from Good Linearizations

Palindromic polynomial eigenvalue problems and related classes of structured eigenvalue problems are considered. These structures generalize the concepts of symplectic and Hamiltonian matrices to matrix polynomials. We discuss several applications where these matrix polynomials arise, and show how linearizations can be derived that reflect the structure of all these structured matrix polynomial...
