Waves and rays in plano-concave laser cavities, Part~II: a semiclassical approach
A. Pascal, S. Bittner, B. Dietz +6
This second paper on the Fabry-Perot cavity presents a semi-classical approach, which means that we consider the transition from wave optics to geometrical optics. The basic concep…
Energy-efficient 8-point DCT Approximations: Theory and Hardware Architectures
R. J. Cintra, F. M. Bayer, V. A. Coutinho +2
Due to its remarkable energy compaction properties, the discrete cosine transform (DCT) is employed in a multitude of compression standards, such as JPEG and H.265/HEVC. Several lo…
Standing on the shoulders of Dwarfs: the Kepler asteroseismic LEGACY sample II - radii, masses, and ages
Victor Silva Aguirre, Mikkel N. Lund, H. M. Antia +21
We use asteroseismic data from the Kepler satellite to determine fundamental stellar properties of the 66 main-sequence targets observed for at least one full year by the mission.…
On the Prym variety of genus 3 covers of genus 1 curves
Christophe Ritzenthaler, Matthieu Romagny
Given a generic degree-2 cover of a genus 1 curve D by a non hyperelliptic genus 3 curve C over a field k of characteristic different from 2, we produce an explicit genus 2 curve X…
The fundamental group of compact K{ä}hler threefolds
Benoît Claudon, Andreas Höring, Hsueh-Yung Lin
Let be a compact K{ä}hler manifold of dimension three. We prove that there exists a projective manifold such that . We also prove the bimeromorphic e…
Upper Limits on the Stochastic Gravitational-Wave Background from Advanced LIGO's First Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +992
A wide variety of astrophysical and cosmological sources are expected to contribute to a stochastic gravitational-wave background. Following the observations of GW150914 and GW1512…
