Impact of Co‐Solvents and Additives on the Indoor Stability of Green Solvent‐Processed Organic Solar Cells

open access: yesSolar RRL, Volume 10, Issue 10, 27 May 2026.
This study investigates the stability of TPD‐3F:FCC‐Cl blends under indoor conditions with various cosolvents and additives. The results reveal significant burn‐in degradation due to morphological instability under mild testing conditions. However, the DBDMF solid additive demonstrates improved stability, attributed to its lower miscibility and more ...

A Prototype Toolkit For Evaluating Indoor Environmental Quality In Commercial Buildings [PDF]

open access: yes, 2013
Measurement of building environmental parameters is often complex, expensive, and not easily proceduralized in a manner that covers all commercial buildings. Evaluating building indoor environmental quality performance is therefore not standard practice.

Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept [PDF]

open access: yes, 2017
Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked.

VAE+DDPG: An Attention‐Enhanced Variational Autoencoder for Deep Reinforcement Learning‐Based Autonomous Navigation in Low‐Light Environments

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 5, May 2026.
Variational Autoencoder+Deep Deterministic Policy Gradient addresses low‐light failures of infrared depth sensing for indoor robot navigation. Stage 1 pretrains an attention‐enhanced Variational Autoencoder (Convolutional Block Attention Module+Feature Pyramid Network) to map dark depth frames to a well‐lit reconstruction, yielding a 128‐D latent code ...

Bridging Color Standards: Aligning the Color‐Aid System with the International Commission on Illumination (CIE) and the Munsell Book of Color Coordinates

open access: yesColor Research &Application, Volume 51, Issue 3, May/June 2026.
The graphical abstract displays 67 color samples from the Color‐aid Corporation “Full Set” (CAC‐314) plotted in the CIE ab chromaticity plane based on the measurements reported in the current article. Each data point represents one color sample, labeled with its Color‐aid code, and positioned according to its measured CIE a* (red‐green axis) and b ...

The Effect of ‘Hydraulic‐Visual’ Interaction on the Intensity of Fish Schooling in the Upstream Movement of Juvenile Silver Carp

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study used juvenile silver carp as model organisms to investigate the combined effects of flow velocity, turbulence kinetic energy and visual cues from obstacles on fish schooling intensity. The experiments demonstrated that schooling intensity is a dynamic behavioural adjustment shaped by the integration of hydraulic constraints, energetic ...
