Ground-based and air-borne lidar for wake vortex detection and characterisation [PDF]

, 2008
In the last two years several ground based and airborne wake vortex campaigns have been performed with the DLR coherent Doppler Lidar. The objectives of those cam-paigns were measurements for comparison with the wake vortex prediction and monitoring ...

Perceived importance and didactic difficulty of chemistry education: Insights from Czech teachers

The Curriculum Journal, EarlyView.
Abstract This empirical study examines how chemistry teachers in lower and upper secondary schools in the Czech Republic evaluate the content of the chemistry curriculum, focussing on its perceived importance and didactic difficulty. Based on a quantitative survey (N = 146), the study provides insight into the pedagogical content knowledge of ...

Spatial variation in liana effects on host‐tree allometry and biomass in an intact tropical forest

Ecography, EarlyView.
Lianas are increasing in abundance across the tropics, yet local spatial variation in their effects on host‐tree allometry and biomass, and the drivers of this variation within forests, remain poorly understood. Using field inventory, drone photogrammetry, and terrestrial laser scanning (TLS) across a 50‐ha plot on Barro Colorado Island, Panama, we ...

Interface Engineering in Piezoelectric‐on‐Insulator Platforms: Coupling of Electrons, Photons, and Phonons for Multifunctional Integration

Electron, EarlyView.
The underlying interface physics and engineering strategies across key POI material systems, including LiNbO3/Si, LiNbO3/SiC, LiNbO3/diamond, and AlN/diamond, were reviewed. The key engineering strategies such as atomic‐scale bonding optimization, nanostructuring, ultrathin phonon‐bridge interlayers, and ferroelectric domain wall engineering for ...

Airborne water vapour and wind lidar measurements of latent heat fluxes during COPS 2007 [PDF]

, 2010
During the Convective and Orographically-induced Precipitation Study (COPS) in July 2007 over the Black Forest Mountains in south-western Germany, tropospheric profiles of water vapour and wind were measured with a differential absorption lidar (DIAL ...

Overcoming spectral limits of perovskite photodetectors for the infrared region

InfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...

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.
