A Test of the Coase Conjecture Using Prices of Electronic Books

Southern 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.

Progress in Explosion Mechanisms and Prevention Technologies for Direct Chill Casting Aluminum Melt Upon Water Contact: A Review

Safety Science and Technology, EarlyView.
Molten aluminum–water explosion triggered by leakage remains the core unresolved safety hazard hindering safe production in aluminum direct chill casting. This review summarizes its explosion mechanism, key influencing factors, prevention technologies, existing gaps, and prospects of intelligent multi‐technology integrated explosion‐proof systems ...

HSPE1 deficiency underlies the crosstalk between metabolic dysfunction‐associated steatotic liver disease and age‐related macular degeneration

VIEW, EarlyView.
Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Emission Tuning of Group 13 DPP‑ Pincer Complexes via the Heavy Atom Effect of the Metal Ion and the Halide Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complete series of all nine variations of complexes (DPP)MX2 (DPP = 2,5‐di(pyridin‐2‐yl)pyrrolide; M = Al, Ga, In; X = Cl, Br, I) reveals that the heavy atom effect of both the metal ion and the halide ligands promote ISC, giving rise to dual fluorescence and phosphorescence emission at 77 K. We report on the synthesis, structural characterization,

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

Integrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective
