Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope [PDF]

, 2002
The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Arabinoxylan‐enriched fraction from durum wheat meal modulates structure, texture, nutritional and sensory properties of extruded snacks

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Arabinoxylans (AX), abundant in wheat bran, represent a valuable yet underutilized fraction of cereal milling by‐products. In this study, an AX‐enriched fraction obtained from durum wheat meal (DWM), produced from defatted durum wheat germ and debranning fractions, was incorporated at increasing levels (0–25%) into pea starch ...

Spherical alveolar shapes in live mouse lungs

Scientific Reports, 2023
Understanding how the alveolar mechanics work in live lungs is essential for comprehending how the lung behaves during breathing. Due to the lack of appropriate imaging tools, previous research has suggested that alveolar morphologies are polyhedral ...

Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

Polymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.
