GRAIN-GRAIN INTERACTION IN OSCILLATING SHEETFLOW

open access: yesCoastal Engineering Proceedings, 1988
Viscous grain-grain interaction is an important aspect of the dynamics of oscillating sheetflow. This interaction between sand grains has been investigated qualitatively in a pulsating water tunnel. Furthermore, experiments concerning the interaction between neutrally buoyant spheres in a Couette flow have been carried out at a scale of 100:1 in a new ...

Leaf longevity and structure, fruit mass and phenology in 52 cultivated varieties and wild accessions of olive

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1193-1206, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although phenology has long been recognized as a critical feature for the adaptation of organisms to their local environment, until recently, phenological events have seldom been considered in the broader context of trait‐based ecology.

A Generic Spinup Procedure to Initialize European Forest State Variables in Land Surface Models

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Forest structure is shaped by forest management practices, land‐use changes, and natural disturbances, including droughts, fires, storms, and insect outbreaks that drive species‐specific and size‐specific mortality. By modifying the carbon‐water‐energy exchanges with the atmosphere, it influences a stand's capacity to buffer against or succumb

Fine-Grained and Coarse-Grained Reactive Noninterference [PDF]

open access: yes, 2014
We study the security property of noninterference in a core synchronous reactive language that we call CRL. In the synchronous reactive paradigm, programs communicate by means of broadcast events, and their parallel execution is regulated by a notion of instant.
