Perceived Lightness Differences in Complex Scenes

open access: yesColor Research &Application, Volume 51, Issue 3, May/June 2026.
Background strongly affects perceived lightness differences. Gray backgrounds and larger separation reduce perceived differences (gap effect). Current color‐difference models poorly predict perception in complex scenes. ABSTRACT Psychophysical experiments were conducted to quantify perceived lightness differences between stimuli presented on three ...

Scaling Lightness and Chroma for Highlight Stimuli in HDR Scenes

open access: yesColor Research &Application, Volume 51, Issue 3, May/June 2026.
Chroma of a stimulus, whose (u′, v′) chromaticities are (0.2011, 0.4684) and have around 1 JNCD (Δu′v′ = 0.0033) to the D65 chromaticities, with the luminance from 0 to 10 000 cd/m2, as calculated using the six models. ABSTRACT Lightness and chroma, which are the key elements in uniform color spaces (UCS) and color appearance models (CAM), play ...

External Vibrations on Early‐Age Concrete: A Review

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Micro‐Stimulation Timing Framed Around an Averaged Theta Period of Stimulation Determines Hippocampal Recruitment in Cued Fear Conditioning

open access: yesHippocampus, Volume 36, Issue 3, May 2026.
ABSTRACT The importance of precise timing of neuronal activity, relative to ongoing slower oscillations, is reshaping the engram theory and our understanding of how memories are encoded and stored. The hippocampal theta‐wave phase‐encoding of neuronal firing predicts behavioral outcomes and cognitive performance in memory tasks.

Atypical presentation of bladder urothelial carcinoma (inverted) with associated abdominal carcinomatosis in a dog

open access: yesVeterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract This case report describes an atypical presentation of a canine urothelial cell carcinoma and its outcome. An 11‐year‐old, male, entire Jack Russell dog was presented with a history of dysuria unresponsive to medical management. An abdominal ultrasound revealed an atypical mural mass‐like lesion, with no evidence of mucosal involvement and ...

The Effect of Periwinkle Shell Ash (PSA) on Geotechnical Properties of Lateritic Soil for Road Construction Application

open access: yesPlatform, a Journal of Engineering
The study explores the enhancement of geotechnical characteristics of lateritic soil sourced from a popular burrow pit site in Kano State, Nigeria, by incorporating Periwinkle Shell Ash (PSA). The soil sample was mixed with 0 to 10% PSA content at 2%

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1556-1584, May 2026.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...
