Mythological Names and dróttkvætt Formulae III: From Metric-Structural Type to Compositional System

open access: yesStudia Metrica et Poetica, 2015
This article explores patterns of language use in oral poetry within a variety of semantic formula. Such a formula may vary its surface texture in relation to phonic demands of the metrical environment in which it is realised. This is the third part of a

Complete characterization of ultrashort pulse sources at 1550 nm [PDF]

open access: yes, 1999
This paper reviews the use of frequency-resolved optical gating (FROG) to characterize mode-locked lasers producing ultrashort pulses suitable for high-capacity optical communications systems at wavelengths around 1550 nm, Second harmonic generation (SHG)

Hipparion tracks and horses' toes: the evolution of the equid single hoof

open access: yesRoyal Society Open Science, 2023
The traditional story of the evolution of the horse (family Equidae) has been in large part about the evolution of their feet. How did modern horses come to have a single toe (digit III), with the hoof bearing a characteristic V-shaped keratinous frog on

Taxonomic re-evaluation of African anuran trypanosomes with the redescription and molecular diagnosis of Trypanosoma (Trypanosoma) nelspruitense Laveran, 1904 and Trypanosoma (Haematomonas) grandicolor Pienaar, 1962

open access: yesParasitology, 2023
The aquatic and terrestrial clades of species of Trypanosoma could provide insight into the evolutionary history of the genus, as well as complementary information for biomedical studies of medically and economically important species of Trypanosoma. The

The impact of pelvic lateral rotation on hindlimb kinematics and stride length in the red-legged running frog, Kassina maculata [PDF]

open access: yesRoyal Society Open Science, 2019
Some frog species, such as Kassina maculata (red-legged running frog), use an asynchronous walking/running gait as their primary locomotor mode. Prior comparative anatomy work has suggested that lateral rotation of the pelvis improves walking performance

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy [PDF]

open access: yes, 2016
Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae.

Frogs (Coqui Frogs, Greenhouse Frogs, Cuban Tree Frogs, and Cane Toads)

open access: yes, 2017
Amphibians are perhaps most well known for their highly threatened status, which often masks appreciation for the great numbers of species that are widespread global invaders (Kraus 2009). Both purposeful and accidental introductions of amphibians have occurred worldwide.

A new Gephyromantis (Phylacomantis) frog species from the pinnacle karst of Bemaraha, western Madagascar [PDF]

open access: yes, 2011
We describe a new mantellid frog of the subfamily Mantellinae from the karstic Bemaraha Plateau, western Madagascar. The new species belongs to the genus Gephyromantis, subgenus Phylacomantis, which previously included G. azzurrae, G.

Revealing Carrier-Envelope Phase through Frequency Mixing and Interference in Frequency Resolved Optical Gating [PDF]

open access: yes, 2015
We demonstrate that full temporal characterisation of few-cycle electromagnetic pulses, including retrieval of the carrier envelope phase (CEP), can be directly obtained from Frequency Resolved Optical Gating (FROG) techniques in which the interference ...
