Phaeocystis Dominance of a Large‐Scale Productivity Anomaly in the Northeast Atlantic Ocean During Spring 2024

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Changes to the North Atlantic spring bloom phytoplankton community structure are expected in response to regional warming trends. In 2024 an extensive body of low chlorophyll water, covering approximately 720,000 km2 in area, dominated the Northeast Atlantic during the peak of the spring bloom period.

Controlling the Abrupt Autofocusing of Circular Airy Vortex Beam via Uniaxial Crystal

open access: yesPhotonics, 2022
The propagation of many kinds of structured light beams in uniaxial crystal has been investigated. However, the investigation of the evolution of these structured light beams after the uniaxial crystal is lacking. In this paper, an evolution formula of a

Effects of Indirect Pupillary Light Reflex Stimulation With Colored Light on Corneal Specular Microscopy Performance in Dogs

open access: yesVeterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective To compare the effects of indirect pupillary light reflex (PLR) stimulation using differently colored lights on corneal specular microscopy performance in dogs and to determine the influence of pupil diameter. Animals Studied 20 client‐owned dogs (38 eyes) with healthy corneas.

Image-free active autofocusing with dual modulation and its application to Fourier single-pixel imaging

open access: yes, 2023
Autofocusing is widely used in applications where sharp image acquisition or projection is needed. Here we report an active autofocusing method that works with wide-field structured illumination and single-pixel detection.

LIBS Elemental Mapping of a Feldspathic Lunar Meteorite: Insights for In Situ Exploration

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract To meet the objectives of the many robotic and human missions planned for the Moon in the coming decade, new scientific instruments are currently under development. Laser‐induced breakdown spectroscopy (LIBS) is a robust technique for quantifying elemental abundances by focusing a pulsed laser to generate a plasma and collecting its emission ...

Characterization and Design Framework for Micro‐ and Nanoscale Printed Metal Interconnects in Hybrid Electronic Systems

open access: yesAdvanced Materials Technologies, Volume 11, Issue 11, 5 June 2026.
This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

Dynamic Control of Circular Airy Beams With Linear Optical Potentials

open access: yesIEEE Photonics Journal, 2012
We investigate the propagation dynamics of radially symmetric, circular Airy beams through a medium having linear optical potentials. On the basis of analytic expressions and numerical calculations, we show that “off-axis” autofocusing can ...

Phosphinate or Urea? Synthesis and Biological Evaluation of Prostate Specific Membrane Antigen‐Targeted Fluorophores With Different Zinc‐Binding Motif

open access: yesChemMedChem, Volume 21, Issue 10, 27 May 2026.
A comparison of two structurally related prostate specific membrane antigen (PSMA)‐targeted fluorophores revealed that the substitution of the urea motif lysine‐urea‐glutamate (KuE) by a phosphinate leads to probes with low nanomolar PSMA‐affinity, good and specific tumor uptake, and low off‐target tissue retention in mice.
