In recognition, discriminators use sensory information to make decisions. For example, honeybee (Apis mellifera) entrance guards discriminate between nest-mates and intruders by comparing their odours with a template of the colony odour. Comb wax plays a major role in honeybee recognition. We measured the rejection rates of nest-mate and non-nest-mate worker bees by entrance guards before and a...

We report on the experimental demonstration of the metrological and spectroscopic performances of a mid-infrared comb generated by a nonlinear downconversion process from a Ti:sapphire-based near-infrared comb. A quantum cascade laser at 4330 nm was phase-locked to a single tooth of this mid-infrared comb and its frequency-noise power spectral density was measured. The mid-infrared comb itself ...

Plotococcus Miller & Denno is synonymized with Leptococcus Reyne (Coccoidea: Pseudococcidae). The genus is redescribed and the adult female of the type species, L. metroxyli Reyne, is redescribed and illustrated. All species hitherto included in Plotococcus are transferred to Leptococcus as L. capixaba (Kondo) comb. nov., L. eugeniae (Miller & Denno) comb. nov., L. hambletoni (Kondo) comb. nov....

Four new species are described: Neohemigaster angustifrons sp.n. from Vietnam, Neohenigaster antropovi sp.n. from the Russian Far East, Neohemigaster tetralineata sp.n. from Taiwan and Pterogenia tenebrica sp.n. from Taiwan. In addition to Neohemigaster ussurica (Korneyev, 2001), six species formerly assigned to Pterogenia are transferred to Neoheinigaster: Neohemigaster eurysterna (Hendel, 191...

Optical-optical double-resonance spectroscopy with a continuous wave pump and frequency comb probe allows measurement of sub-Doppler transitions to highly excited molecular states over wide spectral range high accuracy. We report on assessment characterization in methane measured using 3.3-$\ensuremath{\mu}\mathrm{m}$ optical parametric oscillator as 1.67-$\ensuremath{\mu}\mathrm{m}$ probe. The...

Three new species and one new genus of Uropodina from Tanzania are described and illustrated. They include the second species of the genus Bloszykiella Kontschán, 2010, Bloszykiella grebennikovi sp. nov., and the resurrection and re-definition of the genus Spinosissuropoda Hirschmann, 1979, with description of a new species, Spinosissuropoda tanzanica sp. nov. Five species of Uropoda are transf...

We report the generation of an octave-spanning optical frequency comb in a continuous wave laser pumped microresonator. The generated comb spectrum covers the wavelength range from 990 to 2170 nm without relying on additional external broadening. Continuous tunability of the generated frequency comb over more than an entire free spectral range is demonstrated. Moreover, the linewidth of individ...

The equation that describes the relationship between the applied voltage and the resulting electrostatic force within comb drives is often used to assist in choosing the dimensions for their design. This paper re-examines how some of these dimensions-particularly the cross-sectional dimensions of the comb teeth-affect this relationship in vertical comb drives. The electrostatic forces in severa...

Cercosporoid fungi (former Cercospora s. lat.) represent one of the largest groups of hyphomycetes belonging to the Mycosphaerellaceae (Ascomycota). They include asexual morphs, asexual holomorphs or species with mycosphaerella-like sexual morphs. Most of them are leaf-spotting plant pathogens with special phytopathological relevance. The only monograph of Cercospora s. lat., published by Chupp...

We report on the first demonstration of absolute frequency comb metrology with an optical parametric oscillator (OPO) frequency comb. The synchronously-pumped OPO operated in the 1.5-µm spectral region and was referenced to an H-maser atomic clock. Using different techniques, we thoroughly characterized the frequency noise power spectral density (PSD) of the repetition rate frep, of ...
