Persuasion in the political marketplace: How firms snitch on rivals to encourage regulatory enforcement

Strategic Management Journal, EarlyView.
Abstract Research Summary We study an important, but largely overlooked, non‐market strategy used by firms in the enforcement stage of policy: “snitching,” that is, providing intelligence about potential violations of their rivals in an attempt to persuade regulators to fine them.

On the Interaction of the Photovoltaic Response With Ferroelectric and Magnetic Domains: Magnetoelectric Control of the Photovoltaic Response in BiFeO3 Thin Films

Small Methods, EarlyView.
This study demonstrates tunable photovoltaic responses in pure, polycrystalline BiFeO3 thin films, controlled by external electric and magnetic fields. By aligning ferroelectric domains and leveraging magnetoelectric coupling, the photogeneration is amplified up to seven times.

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Assessing Capability Complexity Using Enterprise Architecture Framework

Systems Engineering, EarlyView.
ABSTRACT This study proposes a structured and quantitative methodology to evaluate the holistic complexity of system‐of‐systems (SoSs), employing the Zachman Architecture Framework (ZAF) as its foundational analytical tool. A five‐phase analytical procedure is developed and empirically validated, encompassing: (1) refinement of complexity measures, (2)

Quantum State‐Resolved Photodissociation Dynamics Study of Transition‐Metal Carbonyl and Nitrosyl

The Chemical Record, EarlyView.
State‐resolved scattering measurements provide experimental visualization of nuclear motions in reacting molecules. Carbonyls and nitrosyls are typical ligands in most of the transition‐metal complexes, which undergo dissociation upon visible and ultraviolet photoexcitation.

An Innovative Approach to Multi‐Valued Logic

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The current generation of computer systems operates on the principles of binary logic, which encompasses both logical and arithmetic operations. However, silicon technology has reached its peak performance, prompting researchers to explore alternative methods for enhancing computational efficiency. One such method is the adoption of Multi‐Valued Logic (

Development of ± 550 kV DC GIS Basin Insulator

High Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

Influence of Arc Faults on Pressure Production Characteristics in AC Turret of UHV Transformers

High Voltage, EarlyView.
ABSTRACT The overpressure caused by arc fault in the oil tank can lead to a transformer explosion. Since the AC turret of transformers serves to connect the transformer windings with the AC busbar, the arc current can be extremely high if an earth fault arc occurs leading to potentially hazardous pressure.
