Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Hardy Spaces of Conjugate Systems of Temperatures

open access: yes, 1998
We define Hardy spaces of conjugate systems of temperature functions on ℝn+1+ . We show that their boundary distributions are the same as the boundary distributions of the usual Hardy spaces of conjugate systems of harmonic functions.

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

open access: yesPest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

Investigating the Environmental Impact of Additive Construction: A Systematic Analysis of the Life Cycle Assessment Studies

open access: yesSustainable Development, EarlyView.
ABSTRACT Additive Manufacturing (AM) has been identified as a potential catalyst for a paradigm shift within the construction industry, due to its capacity to enhance sustainability, reduce waste, and augment design flexibility. This study presents a systematic literature review (SLR) that explores the application of Life Cycle Assessment (LCA) in ...

Beggars as Rational Choosers

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...

Martingale Operators and Hardy Spaces with Continuous Time Generated by Them

open access: yesMathematics
In this paper, we introduce the martingale Hardy spaces and BMO spaces generated by an operator T in continuous time and establish the atomic decomposition theorem of the space HpT under the condition that T is predictable.

A Test of the Coase Conjecture Using Prices of Electronic Books

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.
