We study the temporal coherence of an ultrabroadband frequency comb produced in a degenerate GaAs optical parametric oscillator (OPO) pumped by a stabilized Tm-fiber comb, by observing multiheterodyne beats in the RF domain. We infer that in such a regime the OPO automatically produces a stable frequency comb that is phase and frequency locked to the pump. By varying intracavity dispersion, we ...

Hydrogamasellus alagoensis n. sp. is described based on the morphology of adult females and males collected from litter in the State of Alagoas, Brazil. Six new combinations are proposed, namely A cugamasus avium (Karg, 1976) n. comb., Ologamasus lanceolatus (Karg, 1976) n. comb., Ologamasus microcrinis (Karg, 1979) n. comb., Ologamasus testudinis (Karg, 1976) n. comb., Rykellus longopilus (Kar...

The 16S rRNA gene sequences of 34 named and unnamed clostridial strains were determined by PCR direct sequencing and were compared with more than 80 previously determined clostridial sequences and the previously published sequences of representative species of other low- G + C-content gram-positive genera, thereby providing an almost complete picture of the genealogical interrelationships of th...

The genus Megagraphydrus Hansen, 1999 is revised. Eleven of the twelve previously described species are recognized as valid, with Megagraphydrus wangi Hebauer, 2000 syn. nov. found to be a junior synonym of M. politus Hansen, 1999. Most significantly, Megagraphydrus itself is found to be a junior synonym of Agraphydrus Régimbart, 1903. The species are assigned to the subgenus Agraphydrus. This ...

We report a 10-GHz frequency comb generated by filtering a 333.3-MHz OPO frequency comb with a Fabry-Perot (FP) cavity, which was directly stabilized to the incident fundamental comb. This result is supported by a detailed analysis of the Vernier-effect-induced multiple peaks in the transmitted comb power as the FP cavity spacing is detuned. Modes of the generated 10-GHz comb were clearly resol...

Within the Phenacoccinae (Hemiptera: Coccoidea: Pseudococcidae), there are four nominal genera that include species with clusters or groups of multilocular disc pores and/or oral collar tubular ducts of more than one size, namely Peliococcus Borchsenius (= Spinococcus Borchsenius and Eupeliococcus Săvescu), Peliococcopsis Borchsenius, Erimococcus Ezzat, and Seyneria Goux. This study analysed mo...

OBJECTIVE Because models of attention-deficit/hyperactivity disorder (ADHD) therapeutics emphasize benefits of both enhanced dopaminergic and noradrenergic signaling, strategies to enhance D1 and α2A agonism may yield enhanced clinical and cognitive responses. This study tested the hypothesis that combined effects of a dopamine and noradrenergic agonist, d-methylphenidate extended-release (DMPH...

The genus Curicaberis gen. nov. is described to include the type species, Curicaberis ferrugineus (C.L. Koch, 1836) comb. nov., and eight other species transferred from Olios Walckenaer, 1837: C. abnormis (Keyserling, 1884) comb. nov., C. annulatus (F.O. Pickard-Cambridge, 1900) comb. nov., C. bibranchiatus (Fox, 1937) comb. nov., C. ensiger (F.O. Pickard-Cambridge, 1900) comb. nov., C. ferrugi...

The world genera of Mycetophagidae are reviewed and four new genera described. Several adult features of Mycetophagidae are discussed, and some newly discovered secondary sexual characters are described and illustrated. A key is given to the adults of all mycetophagid genera. The following new genera and species are proposed: Afrotyphaeola gen. n. (South Africa), A. natalensis sp. n. (South Afr...
