Fixpointed Idempotent Uninorm (Based) Logics

Mathematics, 2019
Idempotent uninorms are simply defined by fixpointed negations. These uninorms, called here fixpointed idempotent uninorms, have been extensively studied because of their simplicity, whereas logics characterizing such uninorms have not.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

ChatMolData: A Multimodal Agent for Automatic Molecular Data Processing

Advanced Intelligent Systems, EarlyView.
While large language models (LLMs) struggle with molecular data due to single‐modality limitations, ChatMolData—a multimodal agent for processing databases, images, structure files, and documents—is presented. It combines LLMs with tools for retrieval, structuring, prediction, visualization, and search, achieving > 90% accuracy across 128 tasks.

Dynamics of the Galvanic Replacement Reaction of Silver by Gold: Phenomenological Models for Open Circuit Potential‐Time Responsive Indicator

ChemElectroChem, EarlyView.
This article explores the dynamics of replacing three silver atoms by one gold atom (galvanic replacement reaction [GRR]) within silver nanoparticles. The reaction is tracked experimentally using open circuit potential and then mathematically fitted to a sigmoidal kinetic function inspired by autocatalytic and enzymatic cascade reaction functions to ...

Studying the Outcomes and Mechanisms of Carbocationic Rearrangements Using Algorithm‐Augmented Experimentation

ChemistryEurope, EarlyView.
HopCat, a hybrid algorithm combining rule‐based transformations with quantum‐informed kinetics, can be applied to acid‐catalyzed terpenoid rearrangements. In synergy with human chemists and nuclear magnetic resonance analysis, it facilitates product assignment, candidate selection, and reconstruction of complex mechanistic pathways.

A Van Benthem Characterization Result for Distribution-Free Logics

Logics
This article contributes to recent results in the model theory of distribution-free logics (which include a Goldblatt-Thomason theorem and a development of their Sahlqvist theory) by lifting van Benthem’s characterization result for modal logic to the ...

Mechanisms of Chiral Induction to Foldamer Backbones

Chemistry – A European Journal, EarlyView.
Helical foldamers are often built from achiral components and thus have no inherent bias to their twist sense. This review describes mechanisms for controlling their handedness using appended stereocenters. It examines how point chirality directs the twist sense through a combination of short‐range interactions to the directly attached repeat unit and ...

Artificial Intelligence Revolutionizes Anti‐Infective Drug Discovery: From Target Identification to Lead Optimization

iMetaMed, EarlyView.
Artificial intelligence (AI) technology is revolutionizing antimicrobial drug development. In response to increasingly severe antimicrobial resistance challenges, AI can efficiently predict pathogen evolutionary trends, identify potential drug targets, and accelerate compound design and optimization, thereby significantly shortening the development ...

From wells to windmills: Resource redeployment and new technology investment in the energy sector

Strategic Management Journal, EarlyView.
Abstract Research Summary This study examines how multi‐business firms redeploy resources following an industry shock. Using the case of oil and gas firms diversified into wind power, I show that firms reduced expenditure in oil and gas—particularly on complex offshore projects—while increasing investment in wind after the 2014 oil price crash.
