Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass

Rare Metals, EarlyView.
ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...

Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008 [PDF]

, 2010
The blazar PG 1553+113 is a well known TeV gamma-ray emitter. In this paper, we determine its spectral energy distribution using simultaneous multi-frequency data in order to study its emission processes.

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

Ecological Entomology, EarlyView.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

Finding the Best Nursery: How Habitat Features Shape Juvenile Snapper (Chrysophrys auratus) Density

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
This study examines habitat preferences of juvenile Australasian snapper (Chrysophrys auratus) in northeastern New Zealand, analysing data from 113 stations across structured and unstructured habitats. We investigated how juvenile snapper densities were influenced by environmental factors, including prey availability and physical habitat features ...
