Ditched and walled enclosures in Prehistoric Iberia (4th-3rd millennia cal. BCE): Like oil and water
LucentumIberian Copper Age «ditched» and «walled» enclosure sites are often thought to represent two clearly distinguishable groups of sites. However, the discovery of sites where both ditches and walls are present («mixed sites») complicates things.

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Volatile fatty acids (VFAs) are widely used across industries: as intermediates in chemical production (e.g., solvents and polymers), in pharmaceuticals and cosmetics, and as preservatives and health‐promoting additives in food and animal feed. Emerging applications also include bioplastics, bioenergy, and biotechnology.

Dynamics of Size and Shape Variation During Embryonic Development in the Balkan Crested Newt
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Morphological variance in Triturus ivanbureschi embryos fluctuates during the tailbud phase, coinciding with developmental arrest caused by the balanced lethal system. Prehatching embryos show uniform variance. Our study reveals dynamics of morphological variability during early development and provides a baseline for further studies.

Two‐Block Paths in Oriented Graphs of Large Semidegree
Journal of Graph Theory, EarlyView.ABSTRACT We study the existence of oriented paths with two blocks in oriented graphs under semidegree conditions. A block of an oriented path is a maximal directed subpath. Given positive integers k $k$ and ℓ $\ell $ with k / 2 ≤ ℓ < k $k/2\le \ell \lt k$, we establish a semidegree function that guarantees the containment of every oriented path with ...

Journal of Graph Theory, EarlyView.ABSTRACT Lovász et al. proved that every six‐edge‐connected graph has a nowhere‐zero three‐flow. In fact, they proved a more technical statement, which says that there exists a nowhere‐zero three‐flow that extends the flow prescribed on the incident edges of a single vertex z $z$ with bounded degree. We extend this theorem of Lovász et al.

Fabrication‐Tolerant GaAs/SiN Coupling Above the Loss Threshold for Quantum Photonic Applications
Laser &Photonics Reviews, EarlyView.Reliable low‐loss optical coupling between GaAs and SiN waveguides for heterogeneous integration of single‐photon sources is demonstrated. By developing a fabrication‐aware numerical design approach and accounting for experimentally measured fabrication variations and scattering losses, coupling efficiencies meeting the < 10% loss requirement for ...
