Incentives and motivational crowding to address chronic wasting disease: An experiment with Alberta hunters

Abstract Behavioral interventions, for example, through the use of incentives and information, are widely used by policymakers to induce welfare‐improving behavior. When these interventions are used in specific contexts such as environmental conservation, individual knowledge, ex...

Selecting the number of components in PCA via random signflips

Principal component analysis (PCA) is a foundational tool in modern data analysis, and a crucial step in PCA is selecting the number of components to keep. However, classical selection methods (e.g., scree plots, parallel analysis, etc.) lack statistical guarantees in the increas...

Storage timescales and the crystal growth history recorded in the layered reservoir of the Unit 3 Kulanaokuaiki Tephra Member of the Uēkahuna Ash from Kīlauea volcano

Abstract The Kulanaokuaiki Tephra Unit 3 (900 C.E.) was a subplinian basaltic scoria eruption, the largest known to have occurred at Kīlauea’s summit. The initiation mechanism and cause(s) of this highly hazardous eruption remain poorly understood, particularly as this style of a...

Online Gambling Legalization and Household Credit Card Debt

Abstract Since 2018, the legalization of online gambling in the United States has expanded rapidly, raising concerns about its financial impact on households. This paper examines how legalization affects credit card debt and other financial outcomes using household panel data fro...

Impaired effort perception, not reward sensitivity, impacts the effort-reward trade-off in Parkinson’s disease

Deciding whether and how to act depends on a trade-off between the effort required to execute a given action and the potential reward for completing it. Impairments in this effort-reward trade-off have been proposed to underlie reduced movement vigor, or bradykinesia, in Parkinso...

Rapid general electromagnetic analysis of metallic surfaces via conformal energy minimization

We recently found that the electromagnetic scattering problem can be solved efficiently using an approach that expresses the fields in terms of a set of orthonormal basis functions. In this paper, we apply computational conformal geometry with the conformal energy minimization (C...

Comprehensive characterization and translational implications of the GalnsR384C mouse model of Mucopolysaccharidosis IVA

Abstract Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disorder caused by a deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS), leading to progressive accumulation of keratan sulfate (KS) and chondroitin-6-sulfate (C6S) and resulting in systemic skeletal...

Adapting to virtual service delivery to increase resilience of domestic violence services

Purpose The rapid shift to virtual services precipitated by the COVID-19 pandemic related restrictions forced domestic violence agencies to alter many types of service provision. A survey of service providers assessed these disruptions and identified services where virtual adapta...

Dispersion fromPolarizabilities of Atoms in Molecule:DPAIM

Abstract A new atom–atom dispersion function DPAIM (dispersion from polarizabilities of atoms in molecules) has been developed. The dynamic polarizabilities, both dipole–dipole and quadrupole–quadrupole, of a set of reference molecules obtained from the time-dependent density fun...

Adaptive oncogenesis of β-catenin emerges from declining liver tissue integrity

Abstract Mutations are fundamental to oncogenesis, yet they cannot fully explain cancer progression, as oncogenic mutations frequently accumulate in healthy tissues without immediate malignancy. In the liver, β-catenin mutations are highly prevalent in hepatocellular carcinoma bu...

Rural Community Perspectives on Hurricane Helene in Western North Carolina

Introduction: After making landfall on the Florida Gulf Coast in September 2024, Hurricane Helene impacted Western North Carolina (WNC) with historic flooding, landslides, and hurricane-force winds. More than 100 deaths in the region were attributed to the storm's direct impacts....

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

Beyond the Pandemic in Higher Education

This research explores how people in higher education are experiencing long-term recovery from the COVID-19 pandemic. It seeks to hear from members of college and university communities now that we are over five years past the start of the COVID-19 pandemic, including current und...

Advancing boundary-layer physics via Doppler wind LiDAR dynamic-thermodynamic profiling

Simultaneous, high-resolution measurements of boundary-layer dynamics and thermodynamics remain a longstanding observational challenge. We present a Doppler wind LiDAR–based retrieval that derives virtual potential temperature from TKE-budget buoyancy residuals, enabling concurre...
