Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Lightning Protection Technology for Overhead Insulated Lines of 10kV Distribution Network Based on Linear Least Square Positioning Method

Journal of Applied Science and Engineering
The calculation of the series gap distance of the lightning protection device in the 10 kV distribution network is rough, and the positioning error of the lightning strike point may be large, which affects the stability of electricity consumption ...

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

Journal 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.

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

Journal 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.

Nationalist–Feminine Bifurcation: The Construction of National Morality Through Gender Regimes

Nations and Nationalism, EarlyView.
ABSTRACT This article introduces the concept of nationalist–feminine bifurcation to analyse how nationalist–populist regimes construct moral orders through gendered representations. It explores how women are simultaneously portrayed as the idealized ‘national woman’ and the excluded ‘moral threat’. Through a comparative discourse analysis of four cases—

A High‐Throughput Phenotyping Pipeline for Quinoa (Chenopodium quinoa) Panicles Using Image Analysis With Convolutional Neural Networks

Plant Breeding, EarlyView.
ABSTRACT Quinoa is a grain crop with excellent nutritional properties that has attracted global attention for its potential contribution to future food security in a changing climate. Despite its long history of cultivation, quinoa has been improved little by modern breeding and is a niche crop outside its native cultivation area.
