Radiative Cooling by Green(er) Solvents‐Upcycled Polyvinyl Chloride From Drug Blisters Waste

open access: yesAdvanced Optical Materials, EarlyView.
This study explores upcycling poly(vinyl chloride) (PVC) from used pharmaceutical blisters into sustainable radiative cooling materials. Using solvent separation and membrane fabrication, PVC was converted into white membranes paired with aluminum foil.

Chameleonic Color‐Variable Microbead Emitters for Multilevel Spectroscopic Encryption from Visible to Infrared Wavelengths

open access: yesAdvanced Optical Materials, EarlyView.
Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

open access: yesAdvanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Effectiveness of graph-based and fingerprint-based similarity measures for virtual screening of 2D chemical structure databases [PDF]

open access: yes, 2002
This paper reports an evaluation of both graph-based and fingerprint-based measures of structural similarity, when used for virtual screening of sets of 2D molecules drawn from the MDDR and ID Alert databases.

Losing sleep at the market: An empirical note on the daylight saving anomaly in Australia [PDF]

open access: yes
The ‘daylight saving effect’ predicts that the mean weekend return following the spring and fall/autumn changes in daylight saving time is less than the mean weekend return throughout the rest of the year.

Summertime and the drivin’ is easy? Daylight Saving Time and vehicle accidents. LEQS Paper No. 150/2019 December 2019 [PDF]

open access: yes, 2019
Although it is commonly understood that light conditions affect driving behaviour, detailed evidence is scarce especially for EU countries. In this paper we use the exogenous variation in daylight caused by Daylight Saving Time (DST) shifts to examine ...

Analysis of the daylight performance of a glazing system with Parallel Slat Transparent Insulation Material (PS-TIM) [PDF]

open access: yes, 2017
Daylight plays an important role in the energy efficiency and indoor environmental quality of an office building. An innovative façade system where parallel transparent/translucent plastic slats are sandwiched between glass panes to form a Parallel Slat ...
