The Herfindahl neutral point: A firm‐level threshold for managing market concentration with evidence from US hog packing

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

Dupilumab Beyond the Airway: Decreased Morbidity in a Real‐World Analysis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Post hoc analyses of clinical trials have characterized dupilumab's adverse effects, yet the real‐world impact in chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma is not well described. This study aims to characterize the risks of lymphoma, cardiovascular events, eosinophilia, joint pain, inflammatory arthritis, and ...

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Toward Solution‐Time Advantage With Error‐Mitigated Quantum Annealing for Combinatorial Optimization

open access: yesAdvanced Physics Research, EarlyView.
This paper presents a novel error mitigation technique to address the qubit errors that occur when solving combinatorial optimization problems with quantum annealing. The approach significantly speeds up the computation to reach the global optimum solution for a correlated 3D image segmentation model for material microstructures, demonstrating a ...
