Desertification Risk: Bibliometric Analysis and Future Research Directions

Land Degradation &Development, EarlyView.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Dispersion‐Less Dissipative Soliton Fiber Laser

Laser &Photonics Reviews, EarlyView.
A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

Terrestrial Laser Scanning as an Effective Tool to Retrieve Tree Level Height, Crown Width, and Stem Diameter

Remote Sensing, 2015
Accurate measures of forest structural parameters are essential to forest inventory and growth models, managing wildfires, and modeling of carbon cycle. Terrestrial laser scanning (TLS) fills the gap between tree scale manual measurements and large scale

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers

Laser &Photonics Reviews, EarlyView.
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.

Is There Deep-Seated Subsidence in the Houston-Galveston Area?

International Journal of Geophysics, 2014
Long-term continuous groundwater level and land subsidence monitoring in the Houston-Galveston area indicates that, during the past two decades (1993–2012), the groundwater head has been increasing and the overall land subsidence rate has been decreasing.

Time‐Stretched Interferometric LiDAR with Dispersive Wavenumber‐to‐Time Range Encoding

Laser &Photonics Reviews, EarlyView.
We present a time‐stretched interferometric LiDAR that directly encodes distance into time‐domain interference signals. Operating at 5 MHz with only millimeter‐level coherence length, the system measures up to 12 m with centimeter precision and resolution, achieving high‐speed 3D imaging and dynamic target detection without FFT processing or long ...

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences
