Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams

ABSTRACT Achieving strongly saturated structural coloring in pixels made entirely of low‐index dielectrics, such as polymers or glass, is a challenging task as they lack the index contrast for narrowband resonances. Forming gratings or photonic crystals is an alternative, but the...

Incremental effects for continuous exposures

Causal inference problems often involve continuous treatments, such as dose, duration, or frequency. However, identifying and estimating standard dose-response estimands requires that everyone has some chance of receiving any level of the exposure (i.e., positivity). To avoid thi...

PPARG directs trophoblast cell fate and establishment of the uterine-placental interface

Abstract The expansion and differentiation of trophoblast stem (TS) cells are critical for defining fundamental properties of the placenta. Specialized trophoblast cells called extravillous trophoblast (EVT) cells in human and invasive trophoblast cells in rat, exit the placenta,...

Financial Barriers, Mental Health, and Medication Nonadherence Among Individuals With Chronic Pain

ABSTRACT Introduction Chronic pain has been associated with comorbid psychological symptoms and prescription medication nonadherence, including nonadherence due to financial limitations. Despite noted independent associations with chronic pain, the association of medication nonad...

Decoding Code: Planning Enabling Legislation and the 1975 ALI Model Land Development Code

In 1975, the American Law Institute (ALI) published A Model Land Development Code, a 500-page book designed to reform the foundational laws governing municipal planning in the US. Arising from the urban and environmental crises of the 1960s, the code reflected a broader movement...

Microbial inoculants for soil restoration: A Risk-Proportional Stewardship Framework Integrating Strain-Resolved Genomics and Adaptive Governance

Abstract Global soil degradation and increasing reliance on chemical inputs threaten agricultural sustainability, driving interest in microbial inoculants as tools for soil restoration. These biological products have the potential to enhance nutrient cycling, improve soil structu...

Power distribution system blackstart restoration using renewable energy

Large-scale blackouts continue to expose the fragility of traditional top-down restoration, where end users remain de-energized until bulk generation and transmission are recovered. The rapid growth of inverter-based distributed energy resources (DERs) creates a credible alternat...

Racial negligence, transit, and placemaking: An examination of planning practices

Transportation infrastructure is a core component of the built environment that significantly impacts how residents access services, amenities, jobs, education, and recreation. While other facets of urban studies have begun to reckon with the wicked legacy of racialized infrastru...

BODIPY-Integrated Porous Materials: Design Principles, Functional Architectures, and Emerging Applications

Abstract The incorporation of functional organic chromophores into porous architectures has emerged as a powerful strategy to bridge molecular photophysics with materials-level performance. Among these, boron-dipyrromethene (BODIPY) derivatives offer a unique combination of stron...

Geosynthetic Applications and Design Methods for Paved and Unpaved Road Systems in Minnesota: Review of Current Practice

Geosynthetics are widely used in pavement systems in multiple applications, including base and subgrade stabilization, reduction of layer intermixing and moisture, and mitigation of shrink/swell-related distresses. However, the current geosynthetic classification system and guide...

The AI-Enhanced Transition IEP: A Framework for Ethical, Individualized, and Effective Decision-Making

With the increasing number of students in the United States who qualify for special education and related services, special educators face persistent challenges in developing high-quality, legally defensible individualized education programs (IEPs). Recent research suggests that...

How retailer prestige drives sales performance and turnover: the mediating role of organizational identification and moderating role of professional identification

Purpose Retailer organizational prestige is defined as employees' own beliefs and perceptions about how individuals external to the organization judge and evaluate the status and prestige of their firm. Although researchers and professionals recognize that retailer organizational...

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

ABSTRACT Electrochemical upgrading from CO 2 and CO to ethylene has typically been coupled with the oxygen evolution reaction (OER), whose high standard reduction potential leads to full‐cell voltages above 2.2 V at 200 mA/cm 2 . Here we explored an alternative anodic reaction, w...

Nano MIPs (Molecularly Imprinted Polymers) Prepared From a “Frustrated” Gold Nanoparticle‐Based Pre‐Imprinting Matrix: Enhancing Binding Affinity and Selectivity

ABSTRACT Molecularly imprinted polymers have broad applications in chemistry and biology. Nanomaterials differ substantially from analogous materials on the macroscopic scale. In this work, ligand‐stabilized gold nanoparticles and two micelles with different surfactant structures...

Government Policy, Low‐ and High‐Skilled Labour, and Technical Inefficiency in Chinese Agriculture, 1952–2008

ABSTRACT We utilize Chinese provincial data to explore how government policies affected grain production between 1952 and 2008. We adapt the Caselli‐Coleman framework to allow multiple inputs including fertilizer, land and capital as well as skilled and unskilled labour. We also...

Driver‐Centric Vehicle Routing for Parcel Delivery

ABSTRACT One issue parcel delivery drivers are facing in their workplace is the limited access to restrooms. Because drivers are constantly pressured to meet the demanding performance standards called work quotas, they have little time to visit restrooms while working, often forc...

Centennial Celebration of the Fluids Engineering Division (FED)

Abstract Technology development accelerates economic growth and advances human life. As the Fluids Engineering Division (FED) of the American Society of Mechanical Engineers (ASME) marks its 100th anniversary, we review here the Division's achievements over the years and discuss...

Pathological, microbiological, and molecular characterization of uterine samples in culled sows from farms with a history of reproductive failure in Brazil

Reproductive failure in swine herds is an important cause of production losses and increased sow culling. While many diagnostic efforts focus on abortion-derived samples, the evaluation of reproductive tracts from culled sows may provide additional insights. This study aimed to c...
