Acetylenic coupling is currently experiencing some of the most intensive study of its long
history. Rigid and sterically undemanding di‐ and oligoacetylene moieties, which are frequently …

Ground‐based optical and digital ionosonde measurements were conducted at Thule,
Greenland to measure ionospheric structure and dynamics in the nighttime polar cap F layer. …

A multifrequency (ten spectral lines between VHF and S band) coherent radio beacon is
presently transmitting continuously from a 1000-km, high-inclination orbit for the purpose of …

We address the question regarding the two‐dimensional shape of equatorial plasma
bubbles in the plane transverse to the geomagnetic field. By comparing the east‐west spatial …

Coordinated measurements of F region plasma patches were conducted on February 3/4,
1984, from Thule and Sondrestrom, Greenland. Optical, ionosonde, amplitude scintillation, …

The utility of,/3-unsaturated carbonyl compounds in synthesis and the ease of access to
propargyl alcohols make the conversion of the latter into the former a useful transformation. The …

An investigation of the polar cap ionosphere near the peak of the last solar cycle identified
polar cap F layer arcs and ionization patches as unique features of the polar cap ionosphere, …

The statistics that best describe optical and radio signals that have been scattered by random
refractive-index irregularities have presented an open question for some time. Different …

A high‐performance rocket carrying a four‐frequency, phase‐coherent beacon and full
complement of in situ diagnostic instrumentation was launched into active equatorial spread F on …

Catalytic ruthenium complexes in conjunction with an indium cocatalyst and Brönsted acid
isomerize primary and secondary propargylic alcohols in good yields to provide trans enals …
