A Branched SNF1‐Related Protein Kinase 2 Signalling Cascade Controls ABA‐Induced Ethylene Production and Regulates Both Fruit Ripening and Reproductive Growth

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2657-2672, April 2026.
ABSTRACT Control of fruit ripening, quality and yield is of major scientific, nutritional and commercial importance. The burst of ethylene (ET) production at the initiation of ripening is the most critical event controlling climacteric (CL) fruit ripening, yet little is known about how it is initiated.

Pulp Fiber Bending Stiffness in Wet and Dry State Measured from Moment of Inertia and Modulus of Elasticity

open access: yesBioResources, 2014
The bending stiffness of pulp fibers in both dry and wet states is of great importance with respect to many optical and physical paper properties. We introduce a method that evaluates fiber bending stiffness from the fibers’ Young’s modulus (E) and the ...

Interfacial Energy and Composition Controlled Self‐Stratification in Polyurethane Coatings

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 3, March 2026.
This study elucidates self‐stratification in polyurethane coatings driven by interfacial energies and composition‐dependent phase separation. Using XPS, SIMS, and Raman analyses, we reveal rapid formation of hydrophobic and hydrophilic layers and substrate‐dependent interfacial structures.

Structure, ontogeny and evolution of the patellar tendon in emus (Dromaius novaehollandiae) and other palaeognath birds [PDF]

open access: yes, 2014
The patella (kneecap) exhibits multiple evolutionary origins in birds, mammals, and lizards, and is thought to increase the mechanical advantage of the knee extensor muscles.

Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 285-295, March 2026.
Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.
