New ion trap for atomic frequency standard applications [PDF]

A novel linear ion trap that permits storage of a large number of ions with reduced susceptibility to the second-order Doppler effect caused by the radio frequency (RF) confining fields has been designed and built.

Driving Sustainable Innovation: A Review of Data‐Driven Technologies in Sustainable Business Model Innovation

Business Strategy and the Environment, EarlyView.
ABSTRACT Many companies use data‐driven technologies to drive sustainable business model innovation (BMI), yet often face challenges in doing so effectively. However, the literature at the intersection of data‐driven and sustainable BMI remains conceptually dispersed, limiting theoretical progress and practical application.

Operational modes for a wave injection facility aboard spacelab and a sub-satellite [PDF]

Various modes of operation are described for an orbiting wave injection facility planned to measure the properties of waves propagating in space plasma. Such a facility would cover a wide frequency range including MF and HF. Phase shift and Doppler shift

Electron Density Structure Measurements With Scattered Intense Laser Beam

Contributions to Plasma Physics, EarlyView.
ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.

Numerical investigation on the influence of mesoscopic deformation on contact area and hydraulic aperture to fracture seepage

Deep Underground Science and Engineering, EarlyView.
Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions. In this study, the interactions between fracture closure, contact area, and hydraulic characterization of mesoscopic‐scale rough ...
