Staying sheltered: geographical variation in nestbox use by a nocturnal raptor outside the breeding season

open access: yesWildlife Biology, EarlyView.
Tree cavities and nestboxes are crucial resources for cavity‐nesting birds. While cavities are essential for reproduction, their importance outside the breeding season remains poorly understood, with most existing evidence focusing on nestbox use by small birds to reduce heat loss during winter.

Characterization of Narrow Band Filters for Infrared Astronomy The Brgamma and H_2 filters [PDF]

open access: yes, 1998
We present a characterization of two narrow band filters commonly used in Infrared Astronomy. Our study mainly quantifies the effect of temperature and tilt angle on the central wavelength and width of the transmission bands of such filters.

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

open access: yesIbis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Surface plasmon enhanced infrared photodetection

open access: yesOpto-Electronic Advances, 2019
infrared photodetectors have been used extensively in biomedicine, surveillance, communication and astronomy. however, state of the art technology based on Ⅲ-Ⅴ and Ⅱ-Ⅵ compounds still lacks excellent performance for high-temperature operation.

The use of thermal imaging to assess heat generation during dental implant bed preparation in the presence of a surgical guide with an incorporated coolant channel

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluates the thermodynamic benefits of including an irrigation fluid channel in the design of surgical guides used for dental implant site drilling. Materials and Methods Two types of guides suitable for hosting artificial bone plates that mimic the mechanical properties of human alveolar bone were designed: a classical ...

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

An Improved Atlas of Full-scan Spectra from ISO/SWS

open access: yesThe Astrophysical Journal Supplement Series
We present an atlas of full-scan spectra from the Short-Wavelength Spectrometer (SWS) on board the Infrared Space Observatory after reprocessing and improving an earlier version published 22 yr ago. The SWS spectra cover the wavelength range from 2.35 to
