The slow but steady progression toward environmental sustainability
As 2017 ends and 2018 begins, many of us reflect on the year that has past and think about the year to come. In the United States we have had a year filled with disappointment but sparked by hope. We have a president without a shred of understanding of the nature of the global sustainability crisis who operates as if he is in a time warp stuck in 1975. He is in the process of deconstructing the U.S. EPA, shredding environmental regulations and enforcement, opening up natural treasures to exploitation, discouraging immigration and global trade, and debasing the dignity of his office tweet by tweet. Last week the New York Times' Lisa Friedman, Marina Affo and Derek Kravitz reported that:

New app developed to locate people in areas without a phone signal
Researchers of the Universidad de Alicante (UA) have developed new technology that makes it possible to locate people who have suffered an accident in remote locations without a phone signal and where a speedy rescue is essential to save lives. The system can also be used in emergency situations that arise as a result of earthquakes, floods or forest fires, where mobile phone infrastructure is often rendered useless.

Information extraction and visualization from Twitter considering spatial structure
Social media is expected to be a good source of data for analyzing human behavior and statuses of locations. It is possible to provide location-based information simply by geospatially filtering archived data.

Highly efficient, high-power short-pulse lasers based on Tm3+ doped materials
Highly efficient high power short pulse lasers at the wavelength range of 2 µm based on Tm3+ doped materials have a variety of applications such as material processing, LiDAR, mid-infrared OPOs for wavelengths up to 12 μm, or mid-infrared supercontinuum generation. They also would enable direct coherent soft X-ray generation by high order harmonics generation.

Hierarchical opportunistic routing with moderate clustering for ad hoc networks
The self-organizing nature of ad hoc networks generally has an advantage that the networks are free from fixed infrastructures such as APs (Access points). However, this also has a disadvantage that the networks are unstable and unreliable compared with wired and fixed communication.
