Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

open access: yesThe FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Quality Regulation and Unexpected Gaming: Evidence From Mandating Flight Delay Compensation

open access: yesJournal of Economics &Management Strategy, EarlyView.
ABSTRACT Policies that target a single aspect of agents' motivation may lead to their diminished efforts in other areas. This paper examines the effect of the European Union's flight delay compensation policy on flight on‐time performance by exploiting a unique policy variation in a difference‐in‐differences framework.

Future Increase in Lightning Around the South China Sea Under Climate Change

open access: yesEarth and Space Science
The impact of global warming on lightning flash rates remains relatively unknown. In this study, the South China Sea (SCS) and the surrounding areas within Southeast Asia were selected to examine the long‐term trend and future projection of lightning ...

Natural disaster risk salience and the strategic appointment of directors with sustainability expertise

open access: yesJournal of Financial Research, EarlyView.
Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.

Position paper on the potential of inadvertent weather modification of the Florida peninsula resulting from the stabilized ground cloud [PDF]

open access: yes
Based on the climatology of the Florida Peninsula, we assessed the risk for weather modification. Certain weather situations warrant launch rescheduling because of the risk of possible impact on hurricanes, hail formation and lightning activity, strong ...

The 13 years of TRMM Lightning Imaging Sensor: From Individual Flash Characteristics to Decadal Tendencies [PDF]

open access: yes, 2011
How often lightning strikes the Earth has been the object of interest and research for decades. Several authors estimated different global flash rates using ground-based instruments, but it has been the satellite era that enabled us to monitor lightning ...

AGILE TGFS AND GLOBAL LIGHTNING ACTIVITY

open access: yes, 2011
[1] The AGILE satellite detects Terrestrial Gamma-ray Flashes (TGFs) in the 0.35–100 MeV energy range using its Mini-Calorimeter (MCAL) instrument with an average detection rate of 10 TGFs/month. Thanks to its Low Earth Orbit with only 2.5 degree of inclination, AGILE guarantees an unprecedented exposure above the equator, where both lightning activity

Axial muscle‐fibre orientations in larval zebrafish

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.
