Most high performance GPS receivers today are wideband. In most cases, they require the wider precorrelation bandwidth for enhanced multipath mitigation capability. Wideband receivers, however, are still significantly more susceptible to electromagnetic interference. In addition, they are more likely to produce unacceptably large pseudorange errors in the presence of satellite signal anomalies,...

This is a report on detailed modeling of young high-mass protostellar candidates during their most embedded and obscured phases. We performed narrowband mid-infrared imaging of three candidate high-mass protostellar objects in G11.94-0.62, G29.96-0.02, and G45.07+0.13 at Gemini Observatory using the Thermal-Region Camera and Spectrograph (T-ReCS). The sources were imaged through up to 11 narrow...

Phototherapy with ultraviolet (UV) radiation of wavelengths between 280 and 320 nm (UVB) is a safe and effective treatment for a variety of diseases. In addition to standard broadband UVB (bUVB), narrowband phototherapy with fluorescent bulbs emitting near monochromatic UV around 311 nm (nUVB) has become an important treatment for diseases such as psoriasis, atopic dermatitis and vitiligo. In a...

A narrowband imaging survey of 276 square minutes of arc was carried out at near infrared wavelengths to search for emission line objects at high redshifts. Most of the fields contained a known quasar or radio galaxy at a redshift that placed one of the strong, restframe optical emission lines (Hα, [O III], Hβ, or [O II]) in the bandpass of the narrowband filter. The area weighted line flux lim...

The perception of pitch is a widely studied and hotly debated topic in human hearing. Many of these studies combine functional imaging techniques with stimuli designed to disambiguate the percept of pitch from frequency information present in the stimulus. While useful in identifying potential "pitch centres" in cortex, the existence of truly pitch-responsive neurons requires single neuron-leve...

View angle effects present in vegetation indices are either being seen as unwanted information or as an additional source of information. However, the magnitude of these angular effects remains for most indices unknown. We use the ESA-mission CHRISPROBA (Compact High Resolution Imaging Spectrometer–Project for On-board Autonomy) providing spaceborne imaging spectrometer and multidirectional dat...

Current procedures for oral cancer screening typically involve visual inspection of the entire tissue surface at risk under white light illumination. However, precancerous lesions can be difficult to distinguish from many benign conditions when viewed under these conditions. We incorporated cross-polarization, narrowband reflectance, and fluorescence imaging modes in a portable, robust, wide-fi...

Abstract We present a deep imaging and spectroscopic search for emission from (3200) Phaethon, large near-Earth asteroid that appears to be the parent of strong Geminid meteoroid stream, using 4.3 m Lowell Discovery Telescope. Observations were conducted on 2017 December 14–18 when Phaethon passed only 0.07 au Earth. determine 3 ? upper level dust CN production rates 0.007–0.2 kg s ?1 2.3 × 10 ...
