Leaf traits of dipterocarp species with contrasting distributions across a gradient of nutrient and light availability [PDF]

open access: yes, 2016
Background: Tree species composition at the landscape scale is often tightly associated with underlying soil type in tropical forests. Changes in soil type may have effects on forest structure that drive changes in both light and soil resource ...

How extreme is extreme? An assessment of daily rainfall distribution tails [PDF]

open access: yesHydrology and Earth System Sciences, 2013
The upper part of a probability distribution, usually known as the tail, governs both the magnitude and the frequency of extreme events. The tail behaviour of all probability distributions may be, loosely speaking, categorized into two families: heavy ...

Generalized Parton Distributions of Light Nuclei [PDF]

open access: yesFew-Body Systems, 2021
The measurement of nuclear generalized parton distributions (GPDs) in hard exclusive processes, such as deeply virtual Compton Scattering (DVCS), will be one of the main achievements of a new generation of experiments at high luminosity, such as those under way at the Jefferson Laboratory (JLab) with the 12 GeV electron beam and, above all, those ...

Experimental demonstration of holographic three-dimensional light shaping using a Gerchberg-Saxton algorithm [PDF]

open access: yes, 2005
We use a three-dimensional Gerchberg–Saxton algorithm (Shabtay (2003) Opt. Commun. 226 33) to calculate the Fourier-space representation of physically realizable light beams with arbitrarily shaped three-dimensional intensity distributions.

ρ meson GPDs and IPDs with a light-front constituent quark model [PDF]

open access: yesEPJ Web of Conferences, 2019
We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter

Multiple Phase Stepping Generation in Alkali Metal Atoms: A Comparative Theoretical Study

open access: yesApplied Sciences, 2023
We theoretically demonstrated optical phase switches in light storage-like experiments. Typical light storage (LS) and retrieval experiments consist of the probe field in the probe channel with writing and reading fields across the drive branch, as well ...

Reconfigurable beams with arbitrary polarization and shape distributions at a given plane [PDF]

open access: yes, 2013
Methods for generating beams with arbitrary polarization based on the use of liquid crystal displays have recently attracted interest from a wide range of sources.

Surface Dual Composite Nanostructure for Improving Visible Light Absorption in Thin Silicon Films

open access: yesIEEE Photonics Journal, 2022
Visible light communication has attracted significant attention due to advantages such as high transmission speed, good security, high confidentiality, environmental protection, and lack of need for spectrum authorization.

Distribution of Light: Outer Regions [PDF]

open access: yesSymposium - International Astronomical Union, 1987
The data base of photometric properties of galaxies has grown enormously in the last few years. Surveys in various colors, detailed studies of selected objects, and a swarm of papers with underlying photometric information have invaded the market, fostered by advances in the technology of observations and by improvements and wider availability of ...
