High Resolution X-ray Computed Tomography: An Emerging Tool for Small Animal Cancer Research

open access: yesNeoplasia: An International Journal for Oncology Research, 2000
Dedicated high-resolution small animal imaging systems have recently emerged as important new tools for cancer research. These new imaging systems permit researchers to noninvasively screen animals for mutations or pathologies and to monitor disease ...

A new method for reconstructing brain morphology: applying the brain-neurocranial spatial relationship in an extant lungfish to a fossil endocast [PDF]

open access: yesRoyal Society Open Science, 2016
Lungfish first appeared in the geological record over 410 million years ago and are the closest living group of fish to the tetrapods. Palaeoneurological investigations into the group show that unlike numerous other fishes—but more similar to those in ...

Effect of Glass Fiber Hybridization on the Behavior Under Impact of Woven Carbon Fiber/Epoxy Laminates [PDF]

open access: yes, 2010
The low-velocity impact behavior was studied in hybrid laminates manufactured by RTM with woven carbon and glass (S2) fabrics. Specimens with different thicknesses and glass fiber content (from 0 to 21 vol.%) were tested with impact energies in the range

Exploring Compound Eyes in Adults of Four Coleopteran Species Using Synchrotron X-ray Phase-Contrast Microtomography (SR-PhC Micro-CT)

open access: yesLife, 2022
Compound eyes in insects are primary visual receptors of surrounding environments. They show considerable design variations, from the apposition vision of most day-active species to the superposition vision of nocturnal insects, that sacrifice resolution

Investigation of particle breakage under one-dimensional compression of sand using X-ray microtomography

open access: yes, 2020
Particle breakage alters particle-scale properties of granular soils including particle size, shape, and contact conditions, and changes macroscale properties including soil compressibility, shear ...

Relation between the Initial and Residual Gas Saturations of Gases Trapped by Capillarity in Natural Sandstones

open access: yesJournal of Fluid Science and Technology, 2013
The saturation of gas trapped in porous rocks by capillarity depends on many factors. Herein, we focused on the effect of gas saturation at flow reversal on capillary trapping saturation.

Patterns and Sources of Spatial Heterogeneity in Soil Matrix From Contrasting Long Term Management Practices

open access: yesFrontiers in Environmental Science, 2018
With the advent of computed microtomography (μCT), in situ 3D visualization of soil at micron scale became easily achievable. However, most μCT-based research has focused on visualization and quantification of soil pores, roots, and particulate organic ...

Flat does not mean 2D: Using X‐ray microtomography to study insect wings in 3D as a model for comparative studies

open access: yesMethods in Ecology and Evolution, 2023
While not generally used for relatively flat structures, X‐ray microtomography can provide decisive insights for comparative anatomy and evolutionary studies of flat structures, thereby solving long‐standing ecological and evolutionary issues.
