Dynamics and symmetries of flow reversals in turbulent convection

open access: yes, 2011
Based on direct numerical simulations and symmetry arguments, we show that the large-scale Fourier modes are useful tools to describe the flow structures and dynamics of flow reversals in Rayleigh-B\'enard convection (RBC).

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

open access: yesInsect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Chinese Pangolin Changes Local Vertebrate Assemblages and Contributes to Their Interspecific Interactions by Burrowing and Revisitation

open access: yesIntegrative Zoology, EarlyView.
In this study, we systematically analyzed the utilization patterns of Chinese pangolin burrows by sympatric species in Guangdong Province, China, including differences in species composition using burrow mounds and burrow tunnels. We found that repeated visits to burrows by Chinese pangolin promoted the use of burrows by sympatric species, suggesting ...

The Value of Values: Does Focusing on Sustainability Provide a Competitive Advantage in Forecasting Earnings? La valeur des valeurs : mettre l'accent sur la durabilité confère‐t‐il un avantage concurrentiel dans la prévision des résultats ?

open access: yesContemporary Accounting Research, EarlyView.
ABSTRACT We identify sustainability‐focused analysts using recent advances in machine learning combined with conference call transcripts. Sustainability‐focused analysts issue more accurate earnings forecasts, and the stock market reacts more strongly to their revisions.

Codimension one defects in free scalar field theory

open access: yesJournal of High Energy Physics
We study various aspects of codimension one defects in free scalar field theory, with particular emphasis on line defects in two-dimensions. These defects are generically non-conformal, but include conformal and topological defects as special cases.

Introduction by Klaas Molenaar and Margot Lobbezoo about the diversity of entrepeneurs. Every day we meet entrepreneurs; when we visit the deli at the corner, order a taxi, have a cup of tea in the bar on the other side of the street or go to a hairdresser. They are everywhere and they have many faces. And there are many opinions about entrepreneurship.
