Groundwater Dynamics and Aquifer–Stream Interactions in California’s San Joaquin River Basin: Insights from a Coupled SWAT+ Gwflow Framework

Quantifying groundwater depletion and aquifer–stream interactions in intensively irrigated basins remains a critical challenge for sustainable water management. This study numerically examines these issues in the San Joaquin River Basin (SJRB) using the coupled SWAT+ gwflow frame...

Azimuthal Anisotropy From Multimode Waveform Modeling Reveals Layering Within the Antarctica Craton

The isotropic structure of the crust and upper mantle under Antarctica has been constrained by many studies. However, the depth dependence of seismic anisotropy, a powerful tool to characterize deformation and flow, is still poorly known. Here, we modeled three-dimensional (3-D)...

Safety and Effects of Gildeuretinol Acetate on Retinal Atrophic Lesions in Stargardt Disease

Importance Stargardt disease (STGD) is the most common macular dystrophy, resulting in profound loss of vision. There is no approved treatment. Objective To evaluate the safety and effects of oral gildeuretinol acetate on the growth of retinal atrophic lesions in individuals with...

A Conversation Between Stefano Fanti and Johannes Czernin

![Figure][1] Stefano Fanti, MD Stefano Fanti, MD, was born in Bologna, Italy, where he completed all of his studies and graduated in Medicine and Surgery with honors at the University of Bologna in 1991. He then obtained specialty training in nuclear medicine with honors at the U...

Loss of salt iodization harmed child survival and academic achievement in Ethiopia

Abstract The introduction of salt iodization is associated with improved health and socioeconomic outcomes, but is not yet universally adopted and not always sustained. Using a quasi-experimental event study with difference-in-differences over space and time, we quantify the impa...

Bourgain’s Condition, Sticky Kakeya, and New Examples

Abstract We prove that in all dimensions at least 3 and for any Hörmander-type phase function satisfying Bourgain’s condition, the sticky case of the corresponding curved Kakeya conjecture reduces to the sticky case of the classical Kakeya conjecture. This supports a conjecture o...

Lack of evidence for gene-level convergence linked to evolutionary shifts in torpor among placental mammals

Torpor is a key survival strategy that many avian and mammalian lineages evolved in response to challenging environmental conditions. Whether the independent evolution of torpor in different lineages involved changes in the same genes remains poorly understood. Here, we performed...

Robust inference and correlates from genetic associations with personality

Personality traits describe stable differences in how people think, feel and behave, and how they interact with and experience their social and physical environments1,2. Many questions remain unanswered about associations between DNA and personality traits, such as their robustne...

Workload and Perceived Burden From a National Survey of Surgeons

Importance Surgeon workload is substantial, but data characterizing perceived burden are scarce, limiting workforce planning, surgeon well-being, and patient safety. Objective To characterize surgeon workload and factors associated with perceived burden. Design, Setting, and Part...

Post‐traumatic Psychopathology and Cardiovascular Risk: A Danish Case–Control Study of Sex‐Specific Associations

Background There is increasing recognition that trauma exposure and related psychiatric consequences predict cardiovascular disease risk. However, most research has specifically examined post‐traumatic stress disorder—despite evidence that a range of psychiatric disorders may fol...

Get With The Guidelines–Heart Failure Hospital Participation and Its Association With Guideline-Directed Medical Therapy and Outcomes

Abstract Purpose Despite strong evidence, real-world adoption of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) remains suboptimal. The Get With The Guidelines–Heart Failure (GWTG-HF) program was designed to close gaps in care....

Trade-Offs Between Patient Experience and Health Care Access

Background: Racial and ethnic disparities in patient-reported experiences exist in the Veterans Health Administration (VA) and in VA-paid health care from non-VA providers (“community care”), but how these disparities compare is unknown. Objectives: We compared racial and ethnic...

Care Models for the Genetic Evaluation of Dilated Cardiomyopathy at Sites of the DCM Consortium

Abstract Background Clinical genetic evaluation for patients with dilated cardiomyopathy (DCM) is minimally implemented and models of care are not defined. To understand current genetics care for DCM, a systematic needs assessment was conducted. Methods Principal Investigators (P...

Beyond and Inside the Electrical Double Layer: Molecular‐Level Cation Effects in Aqueous Electrocatalysis

ABSTRACT Electrocatalytic reactions occur at a dynamic, ion‐regulated electrochemical interface, rather than at a static electrode boundary. In electrocatalytic processes such as hydrogen evolution/oxidation and CO 2 reduction, which operate at potentials below the electrode's po...

Assessing the Validity of the Fixed Tree Topology Assumption in Phylodynamic Inference

Abstract Fixed tree topologies are widely used in phylodynamic analyses to reduce computational burden, yet the consequences of this assumption remain insufficiently understood. Here, we systematically assess the impact of various fixed-topology strategies on phylogenetic and phy...

Sensitivity of the Martian Magnetotail to Model Configuration Choices in Multispecies MHD Simulations

Abstract Numerical modeling has been a key component in the study of the Mars space environment, providing a comprehensive global representation that is not always easy to obtain in spacecraft measurements. However, there are inconsistencies in data‐model and model‐model comparis...

Inverse design of bespoke interatomic potentials via active learning by information-matching

Interatomic potentials (IPs) enable large-scale atomistic simulations beyond the reach of first-principles methods, but their predictive reliability depends critically on the selection of training data, quantified uncertainty, and model expressiveness. Active learning (AL) provid...

The Equity‐Minded Board? Leadership, Accountability, and the Future of Community College Governance

ABSTRACT This study examines how community college governing boards can advance racial equity by extending Bensimon's equity‐mindedness to the level of institutional governance. Using document analysis of California Community Colleges (CCC) Board of Governors (BOG) policies and g...

The Art of Printing [3D Engineering & Advanced Geometry]

There are sequences of actions that we repeat everyday. Among them is the printing action: print a numeric paper in pdf format and save it on your computer, or print it using a Xerox Machine or HP-printer. We found out we can do More: Let us Print in 3D Dimension, and investigate...

Needs assessment of medical curricula development for patients with physical, intellectual, and/or developmental disabilities or non-english language preferences

Abstract Objective Individuals with physical, intellectual, and developmental disabilities (P/IDD) and those with non-English language preferences (NELP) experience significant health disparities, which have been traced to inadequacies in medical training. There is a need to crea...
