It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Germanium substitution in CZTS solar cells [PDF]
Copper zinc tin sulfide (Cu2ZnSnS4, CZTS) is a promising non-toxic and earth-abundant material for thin-film solar cells. However, progress in the efficiency of CZTS solar cells is hindered by a large VOC deficit.

Abstract Background Quantitative assessment of myocardial perfusion using 13N‐ammonia PET with compartmental modeling enables evaluation of myocardial flow reserve (MFR) and prediction of patient prognosis. However, the reliability of these assessments can depend on the analytical methods used for quantitation.
