Surface Rotation and Photometric Activity for Kepler Targets. I. M and K Main-sequence Stars [PDF]
Astrophysical Journal Supplement Series, 2019 Brightness variations due to dark spots on the stellar surface encode information about stellar surface rotation and magnetic activity. In this work, we analyze the Kepler long-cadence data of 26,521 main-sequence stars of spectral types M and K in order

Beyond Photometric Loss for Self-Supervised Ego-Motion Estimation [PDF]
IEEE International Conference on Robotics and Automation, 2019 Accurate relative pose is one of the key components in visual odometry (VO) and simultaneous localization and mapping (SLAM). Recently, the self-supervised learning framework that jointly optimizes the relative pose and target image depth has attracted ...

CPz: Classification-aided photometric-redshift estimation [PDF]
A&A 619, A14 (2018), 2018 Broadband photometry offers a time and cost effective method to reconstruct the continuum emission of celestial objects. Thus, photometric redshift estimation has supported the scientific exploitation of extragalactic multiwavelength surveys for more than twenty years.

Photometric Mesh Optimization for Video-Aligned 3D Object Reconstruction [PDF]
Computer Vision and Pattern Recognition, 2019 In this paper, we address the problem of 3D object mesh reconstruction from RGB videos. Our approach combines the best of multi-view geometric and data-driven methods for 3D reconstruction by optimizing object meshes for multi-view photometric ...

An Organic Chemist's Guide to Mediated Laccase Oxidation
ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022 The mediator‐assisted laccase‐catalyzed oxidation of alcohols is a green alternative to established classical synthetic protocols. However, the interaction between laccases, mediators and oxygen comprises a highly complicated, multivariate system. We present a detailed comparative study evaluating the most important components and parameters via an ...

The effect of emission lines on the performance of photometric redshift estimation algorithms [PDF]
, 2021 We investigate the effect of strong emission line galaxies on the performance of empirical photometric redshift estimation methods. In order to artificially control the contribution of photometric error and emission lines to total flux, we develop a PCA-based stochastic mock catalogue generation technique that allows for generating infinite signal-to ...
