Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes

Laser &Photonics Reviews, EarlyView.
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

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

Laser &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 ...

El valor económico del medio ambiente

Ecosistemas, 2006
La economía ambiental y su némesis, la economía ecológica, comenzaron a preocuparse por el medio ambiente en la década de los 70, aunque desde ópticas distintas.

Approaching Gold‐Standard Sensitivity in a Portable and Versatile Gold Nanoprisms Thermoplasmonic Platform for Lateral Flow Detection of Biomolecules

Small, EarlyView.
This study presents a plasmonic thermal lateral flow (ThermoLFA) biosensor for ultrasensitive, early detection of biomolecules. By combining plasmonic gold nanoprisms (AuNPrs) and near‐infrared (NIR) laser activation, it enhances signal output beyond conventional LFAs.

Exhaled Volatile Organic Compounds Identify Allergic Patients Among Individuals With Chronic Rhinitis

Allergy, EarlyView.
Exhaled decane and nonadecane discriminate allergic (AR + LAR) from non‐allergic (NAR + HC) subjects among individuals with chronic rhinitis. LAR patients display higher levels of exhaled nonadecane than NAR individuals at baseline. Subjects with FeNO≥ 25 ppb have higher levels of exhaled decane, nonanal, and styrene than individuals with FeNO < 25 ppb

Tracking the impact of bottom trawling on benthic habitat status

Conservation Biology, EarlyView.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

Ecological Entomology, EarlyView.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .
