Nitrogen Enrichment Enhances Soil Multifunctionality Through Distinct Drivers Across Urban, Suburban, and Rural Forests

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The accelerating pace of urban expansion has profoundly reshaped urban–rural ecosystems, altering soil environments and impairing key ecological services. However, the combined impacts of urban expansion and atmospheric nitrogen (N) deposition on soil multifunctionality—the capacity to sustain multiple ecological processes—remain poorly ...

A novel approach for in situ benthic habitat characterization

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

open access: yesLaser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts

open access: yesLaser &Photonics Reviews, EarlyView.
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Astrometry with the Wide-Field InfraRed Space Telescope

open access: yes, 2017
The Wide-Field InfraRed Space Telescope (WFIRST) will be capable of delivering precise astrometry for faint sources over the enormous field of view of its main camera, the Wide-Field Imager (WFI). This unprecedented combination will be transformative for the many scientific questions that require precise positions, distances, and velocities of stars ...

Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

open access: yesLaser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Two-Step Localization Method for Electromagnetic Follow-Up of LIGO-Virgo-KAGRA Gravitational-Wave Triggers

open access: yesUniverse
Rapid detection and follow-up of electromagnetic (EM) counterparts to gravitational wave (GW) signals from binary neutron star (BNS) mergers are essential for constraining source properties and probing the physics of relativistic transients ...
