Chemical fingerprinting of wood sampled along a pith-to-bark gradient for individual comparison and provenance identification [PDF]

, 2020
Background and Objectives: The origin of traded timber is one of the main questions in the enforcement of regulations to combat the illegal timber trade. Substantial efforts are still needed to develop techniques that can determine the exact geographical

The formation of rings and gaps in magnetically coupled disk-wind systems: ambipolar diffusion and reconnection

, 2018
Radial substructures in circumstellar disks are now routinely observed by ALMA. There is also growing evidence that disk winds drive accretion in such disks.

Effect of the disorder in graphene grain boundaries: A wave packet dynamics study [PDF]

, 2013
Chemical vapor deposition (CVD) on Cu foil is one of the most promising methods to produce graphene samples despite of introducing numerous grain boundaries into the perfect graphene lattice. A rich variety of GB structures can be realized experimentally

Reconstructing groundwater and lake level histories in Northern Wisconsin: isolation of groundwater’s influence on tree rings from climatic and environmental drivers

Environmental Research Letters, 2023
Tree rings can reveal long-term environmental dynamics and drivers of tree growth. However, individual ecological drivers of tree growth need to be disentangled from the effects of other co-occurring environmental and climatic conditions in tree rings to

Projecting future winegrape yields using a combination of Vitis vinifera L. growth rings and soil moisture simulations, northern California, USA

, 2016
Background and Aim We examined the feasibility of projecting future winegrape productivity by using Vitis vinifera L. growth rings as a proxy to winegrape yields. Methods and Results We compared the climate response of V.

Forest Growth Responses to Drought at Short- and Long-Term Scales in Spain: Squeezing the Stress Memory from Tree Rings

Frontiers in Ecology and Evolution, 2018
Drought-triggered declines in forest productivity and associated die-off events have increased considerably due to climate warming in the last decades.

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.
