Doubling constructions and tensor product L-functions: coverings of the symplectic group by Eyal Kaplan

“…Our construction is based on the recent extension by Cai, Friedberg, Ginzburg and the author, of the classical doubling method of Piatetski-Shapiro and Rallis, from rank- $1$ twists to arbitrary rank twists. We prove a basic global identity for the integral and compute the local integrals with unramified data. …”

Walking coral: Complex phototactic mobility in the free-living coral Cycloseris cyclolites. by Brett M Lewis, David J Suggett, Peter J Prentis, Luke D Nothdurft

“…High-resolution time-laps captured the biomechanics of forward motion that appeared driven by three key factors: tissue inflation, which increased contact surface area for lift and friction; the ventral foot/pads, adjusting substrate interaction/friction; and the contraction and twisting of lateral peripheral tissues, which propelled the coral forward in a coordinated manner resembling the pulsed swimming motion of jellyfish. …”

Comparison of different feedback controllers on an airfoil benchmark by L. Michel, C. Braud, J.-P. Barbot, J.-P. Barbot, F. Plestan, D. Peaucelle, X. Boucher

“…The objective is to track the lift command under external wind perturbations. The outcome of this work is the comparison of performances for three control laws that are suitable when little knowledge is known from the physics. …”
