Title: Production of ZBLAN Optical Fiber in Microgravity
Microgravity reduces crystallization of ZBLAN which will make for a lower loss optical fiber when the fiber is drawn in this environment. Relevant data from previous studies and further look at present studies concentrating on electrostatic levitation of ZBLAN which will help elucidate the mechanism for reduction of crystallization in microgravity.

Title: Distributed Acoustic Sensors Based on Time-gated Digital Optical Frequency Domain Reflectometry
This paper presents a review on distributed acoustic sensors (DAS) based on time-gated digital optical frequency domain reflectometry (TGD-OFDR) that we developed in recent years. Two types of fading-free DAS systems adopting phase demodulation and interference-pattern demodulation are introduced, respectively.
