Finding the sweet spot: Shifting optimal climate for maple syrup production in North America

open access: yesForest Ecology and Management, 2019
Climate change is affecting the benefits society derives from forests. One such forest ecosystem service is maple syrup, which is primarily derived from Acer saccharum (sugar maple), currently an abundant and widespread tree species in eastern North ...

Calculation of the deflection of an arched truss with suspended elements depending on the number of panels

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2020
The aim of the work - to propose a scheme and analytical calculation of a statically definable planar truss with a suspended lower belt. Methods. The formula for the dependence of the deflection of the truss under the action of a uniform load on the ...

Perceptions of U.S. and Canadian maple syrup producers toward climate change, its impacts, and potential adaptation measures

open access: yesPLoS ONE, 2019
The production of maple syrup is an important cultural and economic activity directly related to the climate of northeastern North America. As a result, there are signs that climate change could have negative impacts on maple syrup production in the next

Analytical Estimation of the Natural Oscillation Frequency of a Planar Lattice

open access: yesAdvanced Engineering Research, 2023
Introduction. A new scheme of a flat statically determinate regular lattice is proposed. The lattice rods are hinged.   The study aims at deriving a formula for the dependence on the number of panels of the first natural oscillation frequency of nodes ...

MAPLE 2.3.0: an improved system for evaluating the functionomes of genomes and metagenomes

open access: yesBioscience, biotechnology and biochemistry, 2018
MAPLE is an automated system for inferring the potential comprehensive functions harbored by genomes and metagenomes. To reduce runtime in MAPLE analyzing the massive amino acid datasets of over 1 million sequences, we improved it by adapting the KEGG ...

First report of Pleuroceras pseudoplatani on Acer rubrum, A. griseum, A. saccharinum, A. negundo, A. circinatum and A. macrophyllum in Scotland

open access: yesThe Forestry Chronicle, 2018
In September 2016, large necrotic lesions were observed on the foliage of several maples in Aberdeenshire, Scotland. Symptoms resembled giant leaf blotch disease caused by Pleuroceras pseudoplatani (formerly Gnomonia pseudoplatani; Ophiognomia ...
