Some Mirror partners with Complex multiplication

In this note we provide examples of families of Calabi-Yau 3-manifolds over Shimura varieties, whose mirror families contain subfamilies over Shimura varieties. Therefore these original families and subfamilies on the mirror side contain dense sets of complex multiplication fibers. In view of the work of S. Gukov and C. Vafa this is of special interest in theoretical physics.Comment: 7 page

EM-Bird Sensor Data - Product User Guide and Technical Specifications

This document provides a brief overview of the concept of sea-ice thickness sounding using airborne electromagnetic induction, the geophysical parameters sensed by a specific sensor type as well as a technical description of the content and format of the data files containing the unprocessed sensor data. The description of the higher-level geophysical data products is not part of this document and can be found in the scientific literature. Rather, the information here is intended to document the raw sensor data and the general method concept to ensure any use of the raw data in future applications
