Extinction Maps in the WFAU Archives [PDF]

open access: yesarXiv, 2015
A brief set of notes about the database design for 3D maps of dust extinction in the WFAU Archives, which support data from UKIRT-WFCAM, VISTA and VST. The notes also detail typical use cases, such as getting colour-excesses, extinction-corrections, spectral energy distributions and colour-magnitude diagrams and demonstrate the SQL queries to return ...

The Near-Infrared Extinction Law in Regions of High Av

open access: yes, 2005
We present a spectroscopic study of the shape of the dust-extinction law between 1.0 and 2.2um towards a set of nine ultracompact HII regions with Av > 15 mag.

Structured Light Projection Using Image Guide Fibers for In Situ Photo‐biofabrication

open access: yesAdvanced Materials, EarlyView.
Light‐based biofabrication is typically performed with single wavelength light sources and within benchtop devices. This work demonstrates FaSt‐Light (Fiber‐assisted Structured Light) as a new approach to achieve multiwavelength image projection using flexible image guide fibers, which enables a variety of applications for in situ biofabrication ...

Time-resolved extinction rates of stochastic populations

open access: yes, 2010
Extinction of a long-lived isolated stochastic population can be described as an exponentially slow decay of quasi-stationary probability distribution of the population size.

Two Material Properties from One Wavelength‐Orthogonal Photoresin Enabled by a Monochromatic Laser Integrated Stereolithographic Apparatus (Mono LISA)

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Dynamics of a non-autonomous three-dimensional population system

open access: yesElectronic Journal of Differential Equations, 2009
In this paper, we study a non-autonomous Lotka-Volterra model with two predators and one prey. The explorations involve the persistence, extinction and global asymptotic stability of a positive solution.

Challenges and Opportunities of Upconversion Nanoparticles for Emerging NIR Optoelectronic Devices

open access: yesAdvanced Materials, EarlyView.
The special photo‐responsiveness of upconversion nanoparticles has opened up a new path for the advancement of near‐infrared (NIR)‐responsive optoelectronics. However, challenges such as low energy‐conversion efficiency and high nonradiative losses still persist.

Solid Polymer Electrolyte with Compatible Cathode‐Electrolyte Interfacial Design Enabling Lithium Metal Batteries Operation at 4.8 V with Long Cycle Life

open access: yesAdvanced Materials, EarlyView.
This study introduce a novel approach to enhancing cathode‐SPE compatibility by utilizing the same poly(ionic liquid) (PolyIL)‐based material in both the SPE and the cathode binder. A modified biomass‐based PolyIL substrate, enriched with highly negatively charged C═O and ─OH groups, is incorporated into the SPE to improve Li+ migration and strengthen ...
