Neurons of the medial cortex outer plexiform layer of the lizard Podarcis hispanica: Golgi and immunocytochemical studies.
1994
The study of Golgi-impregnated lizard brains has revealed a scarce but heterogeneous neuronal population in the outer plexiform layer of the medial cortex. Some of the neuronal types detected here resemble the neurons of the dentate molecular layer of the mammalian hippocampus. According to their morphology, five intrinsic neuronal types have been clearly identified: short axon aspinous bipolar neuron (type 1, or sarmentous neuron), short axon aspinous juxtasomatic neuron (type 2, or coral neuron), short axon sparsely spinous multipolar neuron (type 3, or stellate neuron), short axon sparsely spinous juxtasomatic multipolar neuron (type 4, or deep stellate neuron, and sparsely spinous juxta…
Sensor Calibration and Registration for Mobile Manipulators
2016
International audience; —This paper describes the methods used to register a mobile manipulator to a workstation to perform assembly tasks. The nonlinear, least square model of the system is formulated and Ceres Solver is used to compute the position of the robot arm relative to the mobile base. The use of non-contact fiducials to test the accuracy and repeatability of the mobile manipulator positioning in the context of an assembly operation is also discussed. Using mathematical methods and indirect measurements it is possible to compute the offset between physical components of the system where direct measurement is not feasible.
Production of Λ and KS0 in jets in p–Pb collisions at √sNN = 5.02 TeV and pp collisions at √s = 7 TeV
2022
The production of Λ baryons and KS0 mesons (V0 particles) was measured in p–Pb collisions at √sNN=5.02 TeV and pp collisions at √s=7 TeV with ALICE at the LHC. The production of these strange particles is studied separately for particles associated with hard scatterings and the underlying event to shed light on the baryon-to-meson ratio enhancement observed at intermediate transverse momentum (pT) in high multiplicity pp and p–Pb collisions. Hard scatterings are selected on an event-by-event basis with jets reconstructed with the anti-kT algorithm using charged particles. The production of strange particles associated with jets pT,jetch>10 and pT,jetch>20 GeV/c in p–Pb collisions, and with …

Twelve species are cited for the first time: Alloxysta arcuata (Kieffer, 1902), Alloxysta brevis (Thomson, 1862), Alloxysta castanea (Hartig, 1841), Alloxysta fuscicornis (Hartig, 1841), Alloxysta mullensis (Cameron, 1883) ; Alloxysta victrix (Westwood, 1833 ); Phaenoglyphis americanaBaker, 1896; Phaenoglyphis calvertiAndrews, 1978; Phaenoglyphis falcataAndrews, 1978; Phaenoglyphis stenosAndrews, 1978; Phaenoglyphis stricta (Thomson, 1877); and Phaenoglyphis villosa (Hartig, 1841). Three new species are described: Alloxysta evenhuisi Ferrer-Suay & Pujade-Villar n. sp., Alloxysta mexicana Ferrer-Suay & Pu…

Eight genera of Charipinae are defined, keyed out, and illustrated. Keys for all charipine species within each valid genus, includingAlloxysta,Apocharips,Dilyta,Phaenoglyphis, andThoreauana, are presented, except forDilapothor,Lobopterocharips, andLytoxysta, which are monotypic. Figures are provided to show the diagnostic morphological features as used in the keys.

2015
ABSTRACT Charipinae Dalla Torre & Kieffer, 1910 material collected during the ATBI of the Mercantour National Park in the Alpes-Maritimes (France) has been studied. Based on the study of 362 specimens, 35 species in four genera have been identified from: 23 Alloxysta Forster, 1869; 10 Phaenoglyphis Forster, 1869; one Apocharips Fergusson, 1986 and one Dilyta Forster, 1869. Of these, 19 species are recorded from France for the first time: Alloxysta abdera Fergusson, 1986; Alloxysta arcuata (Kieffer, 1902); Alloxysta brachycera Hellen, 1963; Alloxysta brevis (Thomson, 1962); Alloxysta fracticornis (Thomson, 1862); Alloxysta mullensis (Cameron, 1883); Alloxysta pilipennis (Hartig, 1840); Allox…
Review of the Neotropical Charipinae (Hymenoptera, Cynipoidea, Figitidae)

First Record ofAlloxystaFörster from Madagascar, with Descriptions of Two New Species (Hymenoptera: Cynipoidea: Figitidae: Charipinae)
2012
The genus Alloxysta is recorded for the first time from Madagascar, with the description of two new species: Alloxysta antananarivoi Ferrer-Suay & Pujade-Villar sp. n. and Alloxysta antsirananae Ferrer-Suay & Pujade-Villar sp. n. Their morphological features and diagnostic characters are discussed and illustrated. This is the second genus of the subfamily Charipinae recorded from Madagascar.
What is Alloxysta fulviceps (Curtis, 1838) (Hymenoptera: Cynipoidea:Figitidae: Charipinae)?
2011
Pujade-Villar, J., Ferrer-Suay, M., Selfa, J. and Alonso-Zarazaga, M.A. 2011. What is Alloxysta fulviceps (Curtis, 1838) (Hymenoptera: Cynipoidea: Figitidae: Charipinae)?. Memoirs of Museum Victoria 68: 67–70. The validity of Alloxysta fulviceps (Curtis, 1838) and its synonymies have been examined. After studying the type series and the taxonomic history of this species, we conclude that the lectotype was wrongly designated. A new lectotype is designated and A. fulviceps is synonymised with A. victrix (Westwood, 1833).
