Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

VST telescope dynamic analisys and position control algorithms [PDF]

open access: yeseConf C011127 (2001) WEAP061, 2001
The VST (VLT Survey Telescope) is a 2.6 m class Alt-Az telescope to be installed on Cerro Paranal in the Atacama desert, Northern Chile, in the European Southern Observatory (ESO) site. The VST is a wide-field imaging facility planned to supply databases for the ESO Very Large Telescope (VLT) science and carry out stand-alone observations in the UV to ...

MODERNIZATION OF AZT-22 TELESCOPE OF MAIDANAK HIGH-ALTITUDE OBSERVATORY: TESTING RESULTS

open access: yesRadio Physics and Radio Astronomy, 2014
The AZT-22 telescope, equipped with the ML09000-65 CCD camera, has shown to be capable of obtaining high-quality images of astronomical objects and thus solving a wide range of observational tasks.

Observations of AGN with the First VERITAS Telescope [PDF]

open access: yesarXiv, 2005
The first VERITAS (Very Energetic Radiation Imaging Telescope Array System) telescope has been in operation at the basecamp of the Whipple Observatory since January 2005. Here we present initial observations of AGN made using this telescope. Although this is engineering data, significant detections of Markarian 421 and Markarian 501 have been achieved.

The Slow‐Rotating Nucleus of Comet C/2013 R1 (Lovejoy)

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The close approach of comet C/2013 R1 (Lovejoy) allowed us to conduct an in‐depth study of the morphology of the inner coma. From the measurement of the dust emission structures expanding near the cometary nucleus in November–December 2013, we derived a slow rotation period of 47.8±1.2$$ 47.8\pm 1.2 $$ h.

Galactic transient sources with the Cherenkov Telescope Array

open access: yes
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low-mass and high-mass X-ray binaries containing compact objects (e.g., novae, microquasars, transitional millisecond pulsars, supergiant fast X-ray transients ...

Redshift‐Agnostic Machine Learning Classification: Unveiling Peak Performance in Galaxy, Star, and Quasar Classification (Using SDSS DR17)

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Classification of galaxies, stars, and quasars using spectral data is fundamental to astronomy, but often relies heavily on redshift. This study evaluates the performance of 10 machine learning algorithms on SDSS data to classify these objects, with a particular focus on scenarios where redshift information is unavailable.
