A novel approach for in situ benthic habitat characterization
Limnology 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.

Demonstration of steering acoustic waves by generalized Eaton lens
, 2018 We demonstrate an acoustic generalized Eaton lens that steers an acoustic wave to a desired angle, to propose a design method for gradient-index devices using the sub-wavelength structure to shape an acoustic wave.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
Laser &Photonics Reviews, EarlyView.The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air
Laser &Photonics Reviews, EarlyView.Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...

Recent Advances in Top‐Down Proteomics for Single‐Cell Research
Mass Spectrometry Reviews, EarlyView.ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

People and Nature, EarlyView.Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...
