Cancelling mod-2 anomalies by Green-Schwarz mechanism with $B_{μν}$

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Shota Saito, Yuji Tachikawa, , , | Summary: We study if and when mod-2 anomalies can be canceled by the Green-Schwarz mechanism with the introduction of an antisymmetric tensor field $B_{munu}$. As explicit examples, we examine $SU(2)$ and more general $Sp(n)$ gauge theories in four and eight […]

Separating the control of moving and holding still in post-stroke arm paresis

Kavli Affiliate: Reza Shadmehr | Authors: Alkis M. Hadjiosif, Kahori Kita, Scott T. Albert, Robert A. Scheidt, Reza Shadmehr and John W. Krakauer | Summary: Moving and holding still have been posited to be under separate control regimes for both eye and arm movements. The paretic arm after stroke is notable for abnormalities both at […]

Sex chromosome gene expression associated with vocal learning following hormonal manipulation in female zebra finches

Kavli Affiliate: Erich Jarvis | Authors: Matthew Davenport, Ha Na Choe, Hiroaki Matsunami and Erich D Jarvis | Summary: Zebra finches are sexually dimorphic vocal learners. Males learn to sing by imitating mature conspecifics, but females do not. Absence of song in females is associated with atrophy and apparent repression of several vocal learning brain […]

Dynamical time and Ashtekar variables for the Husain-Kuchař model

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano, Eduardo J. S. Villaseñor, | Summary: The relation between the Husain-Kuchav{r} model and some extensions thereof that incorporate a dynamical time variable is explored. To this end, we rely on the geometric approach to the Hamiltonian dynamics of […]

A long-duration superflare on the K giant HD 251108

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hans Moritz Günther, Dheeraj Pasham, Alexander Binks, Stefan Czesla, Teruaki Enoto | Summary: Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set limits on the magnetic field strength and thus constrain the […]
