High-brilliance betatron gamma-ray source powered by laser-accelerated electrons
Julien Ferri, Sébastien Corde, Andreas Döpp +8
Recent progress in laser-driven plasma acceleration now enables the acceleration of electrons to several gigaelectronvolts. Taking advantage of these novel accelerators, ultra-shor…
High-charge relativistic electron bunches from a kHz laser-plasma accelerator
Dominykas Gustas, Diego Guénot, Aline Vernier +5
We report on electron wakefield acceleration in the resonant bubble regime with few-millijoule near-single-cycle laser pulses at a kilohertz repetition rate. Using very tight focus…
Observation of large multiple scattering effects in ultrafast electron diffraction on single crystal silicon
I. Gonzalez Vallejo, G. Gallé, B. Arnaud +8
We report on ultrafast electron diffraction on high quality single crystal silicon. The ultrafast dynamics of the Bragg peaks exhibits a giant photo-induced response which can only…
Spectral asymptotics for -interactions on sharp cones
Thomas Ourmières-Bonafos, Konstantin Pankrashkin, Fabio Pizzichillo
We investigate the spectrum of three-dimensional Schrödinger operators with -interactions of constant strength supported on circular cones. As shown in earlier works, such opera…
Fast calibrated additive quantile regression
M. Fasiolo, S. N. Wood, M. Zaffran +2
We propose a novel framework for fitting additive quantile regression models, which provides well calibrated inference about the conditional quantiles and fast automatic estimation…
Food Productivity Trends from Hybrid Corn: Statistical Analysis of Patents and Field-test data
Mariam Barry, Giorgio Triulzi, Christopher L. Magee
In this research we study productivity trends of hybrid corn - an important subdomain of food production. We estimate the yearly rate of yield improvement of hybrid corn (measured…
