Paying upfront: successful initial infections protect against severe future infections

Abstract Understanding the consistency with which individual hosts respond to repeated pathogen exposures is crucial for accurately modeling pathogen transmission and eco-evolutionary dynamics. When hosts face repeated pathogen exposures, immune memory is expected to reduce the p...

Robustness of Regionally Derived, Short-Duration Rainfall Depth-Duration-Frequency Estimates to the Choice of Minimum Interevent Time: Evidence across Climates, Rain Gauge Densities, and Regionalization Approaches

Abstract The choice of minimum interevent time (MIT)—a criterion used to discern independent events from a continuous rainfall record—can affect the resulting partial duration series (PDS) and depth-duration-frequency values (DDFs). However, the mechanisms by which MIT choice aff...

Obstructive shock from delayed blunt cardiac injury after chest trauma

Blunt cardiac injury (BCI) is a rare but serious presentation in emergency departments (EDs) nationwide. These injuries arise in trauma and may be accompanied by confounding injuries that complicate the clinical picture. Timely recognition is crucial, as BCI may lead to complicat...

Searching for the elusive “A” horizon in buried paleosols

ABSTRACT Presence of an A horizon in paleosols is important for taxonomic classification, interpreting pedogenic processes, and reconstructing paleoenvironments. However, identifying the A horizon in buried contexts is challenging because of potential erosion during burial and po...

Copper–SodiumLignosulfonate Antifouling-CoatedIon-Selective Electrodes for Reliable Long-Term Ammonium Monitoringtoward Data-Driven Wastewater Control

Abstract Ammonium (NH4+) monitoring is essential for process control and effluent compliance in wastewater treatment, but conventional grab sampling provides delayed, discrete measurements that cannot capture rapid concentration fluctuations. Solid-state ion-selective electrodes...

How do Americans and Chinese in greater China living in the United States self-disclose in online dating profiles? A content analysis

Abstract Purpose The goal of the study is to examine how Americans and Chinese in the United States self-disclose in online dating profiles. It also examines how men and women self-disclose in online dating profiles. Design/methodology/approach A content analysis of 400 online da...

Illegal markets for cigarettes and e-cigarettes

This paper discusses the long-standing illegal markets for cigarettes and the more recently emerged illegal markets for e-cigarettes. We identify three distinctive market fundamentals that help explain many features of the illegal markets. First, in contrast to some illegal goods...

Designing Reliable Care Through Clinical Pathways: A Human Factors Framework

Background/Objectives: Healthcare delivery systems are inherently complex, and efforts to improve quality and safety often fail to achieve sustained, system-wide impact because of misalignment between work system design, care processes, and clinical practice. This article present...

Minimal self-sentience

Abstract This article develops the concept of minimal self-sentience to extend the phenomenological notion of minimal self-awareness to non-human animals. Drawing on the phenomenological account of minimal pre-reflective self-awareness (e.g., Zahavi), and on the view that such a...

Deformation mechanism in laser-powder bed fused Ti-6Al-2Sn-4Zr-2Mo alloy: Role of heat treatment

The deformation mechanisms of heat-treated laser powder bed fused Ti-6Al-2Sn-4Zr-2Mo were investigated using tensile testing and transmission electron microscopy. Heat-treated conditions (solutionized and solutionized + aged) showed improved ductility and non-monotonic strain-har...
