Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Dual-Wavelength Single-Longitudinal-Mode Polarization-Maintaining Fiber Laser and Its Application in Microwave Generation

, 2009
A novel approach for generating high-frequency microwave signals is proposed and experimentally demonstrated. With a pair of wavelength matched fiber Bragg gratings written directly in a polarization-maintaining erbium-doped fiber, a stable short cavity ...

When Virchow's law fails: Crouzon syndrome as a test case for quantitative suture closure–endocranial shape relationships

Journal of Anatomy, EarlyView.
Crouzon syndrome shows preserved intracranial volume but profoundly altered endocranial shape, with disrupted allometric coupling relative to controls. Treating calvarial suture patency as a continuous, age‐adjusted variable reveals strong system‐level covariation with endocranial morphology, effects invisible to conventional categorical suture scoring.

Single mode interband cascade lasers based on lateral metal gratings [PDF]

, 2014
The authors are grateful to the European Union for financial support of this work within the FP7 project “WideLase” (No. 318798).Single mode distributed feedback (DFB) interband cascade lasers were realized by placing metal gratings laterally to dry ...

Tailoring Radial Dopant Homogeneity in Silica‐Based Laser Active Media Using Variable SiO2 Precursors in Atmospheric Pressure Plasma‐Based Nanoparticle Synthesis

Particle &Particle Systems Characterization, Volume 43, Issue 10, October 2026.
The study compares two silica precursors, TEOS and OMCTS, for producing Yb2O3, Al2O3‐doped nanoparticle aggregates via atmospheric microwave plasma. TEOS‐based sol–gel precursors yield 20‐40 times higher dopant homogeneity in vitrified samples than OMCTS‐based emulsions. This difference is attributed to distinct evaporation behaviors and water content,

Single mode EDF fiber laser using an ultra-narrow bandwidth tunable optical filter [PDF]

, 2015
Single longitudinal mode (SLM) erbium-doped fiber (EDF) laser operation using a commercialized ultra-narrow bandwidth optical filter has been studied. A two-meter long EDF with an absorption coefficient of 24 dBm-1 at the pump wavelength is used as gain ...

Dynamic Generation of Spatially Variable Vector Beams Using Cascaded Moiré Metasurfaces

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A three‐layer cascaded moiré metasurface dynamically generates vector beams with tunable polarization order and controllable lateral focal positions. Relative rotation of the first two layers adjusts the conjugate OAM components that form the vector beam, whereas the third layer steers its focus across the transverse plane, preserving the dominant OAM ...
