Combining electronic structure calculations and machine learning (ML) techniques has become a common approach in the atomistic modelling of matter. Using the two techniques together has allowed researchers, for instance, to create models that use atomic coordinates as the only inputs to inexpensively predict any property that can be computed by the first-principles calculations that had been used to train them.
While the earliest and by now most advanced efforts have focused on using predictions of total energies and atomic forces to construct interatomic potentials, more recent efforts have targeted additional properties of crystals and molecules such as ionization energies, NMR chemical shieldings, dielectric response properties and charge density. In the paper Learning the electronic density of states in condensed matter, Ceriotti and colleagues focus on the electronic density of states (DOS), another quantity that underlies many useful materials pr
WASHINGTON – The U.S. Naval Research Laboratory today announced the following executive leadership appointments:
Stephen Meier, Ph.D., as director of the Naval Center for Space Technology. NCST’s core mission is to develop innovative basic and applied research through advanced development of spacecraft technology and ground command and control stations.
Stanley Chincheck, as superintendent of the Information Technology Division. ITD is responsible for conception, planning, and execution of research and development programs in the major areas of artificial intelligence and intelligent autonomy, information assurance and software development, networking and communications, knowledge management and decision support, and cybersecurity.
Virginia DeGiorgi, Ph.D., as superintendent of the Materials Science and Technology Division. The division performs multidisciplinary basic and applied research, focusing on scientific discovery and technological exploitation of fundamental mate

The US Defense Advanced Research Projects Agency (DARPA) has awarded five contracts and selected one government partner to develop technology to capture potable water from the air in quantities sufficient to meet critical DoD needs, even in extremely dry climates.

NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth.
Together, NASA’s contribution to the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE, will help us understand the Sun and Earth as an interconnected system.
Understanding the physics that drive the solar wind and solar explosions – including solar flares and coronal mass ejections – could one day help scientists predict these events, which can impact human technology and explorers in space.
