Multi-frequency radio continuum mapping of giant radio galaxies [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 1997
The giant radio galaxies NGC 315, DA 240, 3C 236, 3C 326, and NGC 6251 have been observed at 92 cm and 49 cm wavelengths with the Westerbork Synthesis Radio Telescope (WSRT) and at , 6.3 cm, and 2.8 cm using the Effelsberg 100-m telescope. These objects all exhibit strong polarized radio emission across the entire radio frequency domain. Their spectral

Radio Continuum Observations of the Nuclei of Nearby Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1982
A survey has been carried out at Jodrell Bank of the continuum radio emission from nearby galaxies. The objects include normal galaxies, Seyfert galaxies and others with nuclei active at optical and radio wavelengths.

Radio Continuum Observations of the Nucleus of our Galaxy and Other Normal Galaxies [PDF]

open access: yesHighlights of Astronomy, 1980
The radio properties of the nuclei of normal galaxies have been reviewed by Ekers (1974, 1978a, 1978b) and of the Galactic Centre by Oort (1977). In this report I will concentrate on material available since then. The following paper by Van der Hulst extends this review with more information on the structure of the central sources in normal galaxies.No

Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

open access: yesWildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

open access: yesJournal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Survey on Visualization of Information Diffusion over Networks

open access: yesComputer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

Radio continuum emission in ring galaxies

open access: yesThe Astronomical Journal, 1980
Radio emission was found in two (Arp 118 and Arp 148) of 27 ring-type galaxies searched with the NRAO interferometer to a detection limit of about 10 mJy at 11.1 cm. These two were also observed at 6 cm with the higher sensitivity and resolution of the VLA.
