The Tin Man didn’t have one. The Grinch’s was three sizes too small. And for soft robots, the electronically powered pumps that function as their “hearts” are so bulky and rigid, they must be decouple...
Research on single hole heat transfer power of ground source heat pump system
Ground source heat pump Monitoring Heat transfer power Thermal response test

Two types of biodegradable hydraulic fluids (HEES and HEPR) with the mineral oil-based hydraulic fluid (HV) were
compared. The tests were performed using a test bench. During the tests with a tracto...
Diagrammatic pump-probe approach to coherent backscattering of laser light by cold atoms: Double scattering revisited
Diagrammatic pump-probe coherent backscattering of laser light cold atoms Double scattering revisited Atomic Physics

We present a diagrammatic derivation of the coherent backscattering spectrum from two two-level atoms using the pump-probe approach, wherein the multiple scattering signal is deduced from single-atom ...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
