Single and Bi‐Layer Glass‐Based Phantoms: Robust Materials for a Calibration Standard for Fluorescence Imaging Systems

Advanced Photonics Research, EarlyView.
Fluorescence‐guided surgery is a common technique and characterizing imaging performance is important to ensure clinical reliability. A calibration standard comprising multiple glass phantoms fabricated to mimic the optical properties of fluorescent and non‐fluorescent tissue is presented.

Variations in the Radius Distribution of Single- and Compact Multiple-transiting Planets

The Astronomical Journal
Previous work has established the enhanced occurrence of compact systems of multiple small exoplanets around metal-poor stars. Understanding the origin of this effect in the planet formation process is a topic of ongoing research.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Nongravitational Forces in Planetary Systems

The Planetary Science Journal
Nongravitational forces play surprising and, sometimes, centrally important roles in shaping the motions and properties of small planetary bodies. In the solar system, the morphologies of comets, the delivery of meteorites, and the shapes and dynamics of

The Kepler Follow-up Observation Program

, 2010
The Kepler Mission was launched on March 6, 2009 to perform a photometric survey of more than 100,000 dwarf stars to search for terrestrial-size planets with the transit technique. Follow-up observations of planetary candidates identified by detection of

Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

Advanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications. The

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

Advanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...
