Rydberg ionization spectroscopy is a spectroscopy technique in which multiple photons are absorbed by an atom causing the removal of an electron to form an ion.
Resonance-enhanced multiphoton ionization (REMPI) is a technique applied to the spectroscopy of atoms and small molecules. In practice, a tunable laser can be used to access an excited intermediate state. The selection rules associated with a two-photon or other multiphoton photoabsorption are different from the selection rules for a single photon transition. The REMPI technique typically involves a resonant single or multiple photon absorption to an electronically excited intermediate state followed by another photon which ionizes the atom or molecule. The light intensity to achieve a typical multiphoton transition is generally significantly larger than the light intensity to achieve a single photon photoabsorption. Because of this, a subsequent photoabsorption is often very likely. An ion and a free electron will result if the photons have imparted enough energy to exceed the ionization threshold energy of the system. In many cases, REMPI provides spectroscopic information that can be unavailable to single photon spectroscopic methods, for example rotational structure in molecules is easily seen with this technique.
The Hanseman languages are a group of relatively closely related languages in New Guinea, spoken in the Hansemann Range of mountains. "Closely related" is relative to the situation in New Guinea. Ethnologue notes that Wagi, for example, may be most closely related to Nobonob, yet they are only 30% lexically similar.

Atmospheric pressure laser ionization is an atmospheric pressure ionization method for mass spectrometry (MS). Laser light in the UV range is used to ionize molecules in a resonance-enhanced multiphoton ionization (REMPI) process. It is a selective and sensitive ionization method for aromatic and polyaromatic compounds. Atmospheric photoionization is the latest in development of atmospheric ionization methods.
Okka Disk is an independent American jazz record company and label founded in Chicago by Bruno Johnson in 1994.
Simpatico is an album by American jazz reedist Ken Vandermark, which was recorded in 1998 and released on Atavistic. It was the third recording of the Vandermark 5, the first with Dave Rempis replacing former saxophonist Mars Williams.
Circuitous is an album by jazz pianist Pandelis Karayorgis, which was recorded in 2012 and released on Driff, an artist-run label co-founded by Karayorgis and Jorrit Dijkstra. He leads a new band with four Chicago-based musicians: saxophonists Dave Rempis and Keefe Jackson, bassist Nate McBride and drummer Frank Rosaly. Karayorgis explains that Tony Williams' seminal album Spring inspired the instrumentation for this project, a quintet with two tenors as the main horns.
