Retrieving Forest Canopy Elements Clumping Index Using ICESat GLAS Lidar Data
Clumping index (CI) is a canopy structural variable important for modeling the terrestrial biosphere, but its retrieval from remote sensing data remains one of the least reliable.

Fundamental gaps of the fractional Schrödinger operator
We study asymptotically and numerically the fundamental gap -- the difference between the first two smallest (and distinct) eigenvalues -- of the fractional Schrödinger operator (FSO) and formulate a gap conjecture on the fundamental gap of the FSO.

Retrieving Leaf Area Index (LAI) Using Remote Sensing: Theories, Methods and Sensors
The ability to accurately and rapidly acquire leaf area index (LAI) is an indispensable component of process-based ecological research facilitating the understanding of gas-vegetation exchange phenomenon at an array of spatial scales from the leaf to the

The leaf area index (LAI) is a crucial structural parameter of forest canopies. Light Detection and Ranging (LiDAR) provides an alternative to passive optical sensors in the estimation of LAI from remotely sensed data. However, LiDAR-based LAI estimation

Scaling relations for gaps in fractional quantum Hall states [PDF]
The microscopic approach of Murthy and Shankar, which has recently been used to calculate the transport gaps of quantum Hall states with fractions p/(2ps+1), also implies scaling relations between gaps within a single sequence (fixed s) as well as between gaps of corresponding states in different sequences.

Olive Crown Porosity Measurement Based on Radiation Transmittance: An Assessment of Pruning Effect
Crown porosity influences radiation interception, air movement through the fruit orchard, spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop an accurate and reliable methodology based on transmitted ...
