Increased maximum carbon release offsets half of the growth trend in annual land carbon sink

The terrestrial carbon sink has strengthened in recent decades through enhanced maximum CO2 uptake (MCU) and a longer carbon uptake period (CUP), whereas maximum CO2 release (MCR) remains less quantified. Using atmospheric inversion estimates and 16 terrestrial biosphere models,...

Modeling and Design Optimization of Looped Water Distribution Networks using MS Excel: Developing the Open-Source X-WHAT Model

Abstract Cost-effective water distribution network (WDN) design is crucial for reliable urban water supply. This paper introduces the open-source Excel for Water system Hydraulic Analysis Tool (X-WHAT) for WDN simulation and preliminary design. Unlike traditional spreadsheet appr...

Parabens and estrogen-mediated cancers: unraveling coincidence, co-occurrence, and causality

Abstract Paraben esters are endocrine disruptors linked to breast cancer, yet their role in other estrogen-mediated cancers remains limited. Preclinical evidence suggests that parabens accumulate in tissues and may promote carcinogenesis, while clinical data indicate widespread e...

The First Highly Contiguous Genome Assembly for the Western bluebird ( Sialia mexicana )

The western bluebird (Sialia mexicana) is a secondary cavity-nesting thrush that has experienced historical population declines, local extirpations, and more recent recoveries associated with nest box programs. Despite these regional successes, recent eBird estimates suggest cont...

Challenges in evaluating associations among vasopressors, enteral nutrition, and nonocclusive mesenteric ischemia

Abstract Purpose Acute mesenteric ischemia is a potentially life-threatening condition resulting from thromboembolic occlusion or nonocclusive mechanisms such as vasospasm and excessive vasoconstriction. Nonocclusive mesenteric ischemia (NOMI) is of particular concern in critical...

Recent strengthening of eastern Pacific ENSO in the last millennium paleorecord

The Pacific El Niño–Southern Oscillation (ENSO) generates climate extremes that endanger ecosystems, infrastructure, and human well-being worldwide. The response of this system to climate warming is poorly constrained, due both to data scarcity and uncertainties in climate models...

Evaluating interactive effects of the Conservation Reserve Program and wind energy infrastructure on grassland bird abundance in the United States

Abstract The extent of grasslands has contracted globally, leading to significant declines in grassland-obligate species, including birds. Grassland birds are threatened by multiple factors, including grassland conversion to cropland, and development, including energy infrastruct...

Action Research in Systems Engineering Doctoral Dissertations: Common Pitfalls and Guidance for Effective Use

ABSTRACT Action research (AR) has become an increasingly popular methodology in systems engineering doctoral dissertations, particularly in European academic contexts where industry‐embedded research is valued. Despite its appeal, many doctoral candidates misapply the method in w...

Psychological pathways linking generative AI dependency to psychological capital depletion among Chinese international students

With the widespread use of generative AI in academic writing, language processing, and learning-support contexts, GAD has continued to rise. This study examines whether GAD is associated with rPsyCap and tests the mediating roles of PSD and rSE, both as independent mediators and...

APRN education plus professional development focus on leadership roles and responsibilities

ABSTRACT: The collection of papers featured in the special issue highlights educational strategies for preparing APRN students for practice, academic partnerships to improve DNP student experiences, examining NP student mentors' practice output, and professional roles expected of...

P1.021. Esophageal Reconstruction in an Adult with Failed Colonic Interposition and Recurrent Aspiration

Abstract Topic Benign Disease: Esophageal Surgery Case Submission We present a 23-year-old male with a history of tracheoesophageal fistula repaired in childhood with multiple revisions including a esophagostomy and ultimately a colonic interposition. He continued to have recurre...

P1.020. Real-World Deviations From Standard Adjuvant Immunotherapy After Esophagectomy

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Adjuvant IO is recommended within 4–16 weeks post-esophagectomy, but delays and interruptions are common in practice. Trials like CheckMate 577 permitted treatment delays of up to 10 weeks. We evalua...

The clinical and molecular spectrum of AGO2-associated Lessel-Kreienkamp neurodevelopmental syndrome

Abstract Background Pathogenic variants in AGO2 ,encoding a central component of the RNA-induced silencing complex (RISC), cause the neurodevelopmental disorder Lessel-Kreienkamp syndrome (LESKRES). The variant spectrum and associated molecular mechanisms underlying phenotypic va...

Social Performance Feedback and Managerial Moral Self-Regulation: The Microfoundations of Corporate Social (Ir)Responsibility

Despite growing interest in the microfoundations of corporate social activities, prior research has not articulated the full chain connecting firm-level conditions to managers' psychological processes (a topdown pathway) and back to firm-level corporate social behavior (a bottom-...

The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1

Abstract We present deep Hubble Space Telescope (HST) imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an enigmatic and diverse population, with evolutionary pathways ranging...

A Bayesian approach to postfire debris-flow probability modeling for southern California, United States

Background Intense rainfall on steep, burned landscapes can initiate postfire debris flows (PFDFs). Watershed-scale estimates of PFDF probability in response to a given rainfall intensity are beneficial for assessing PFDF hazards, including prioritizing areas for hazard mitigatio...

Discovery and Characterization of Inhibitors of Ubiquitin-Like Modifier Activating Enzyme 5 (UBA5): Targeting the UFMylation Pathway in Cancer and Neurodegenerative Diseases

Abstract UBA5 is the E1 enzyme that initiates UFMylation, a ubiquitin-like modification implicated in proteostasis, neurodegeneration, and cancer. Here, we report a chemical biology approach to interrogate UBA5 function through small-molecule inhibition. We developed a robust hig...

Cryotherapy for Subglottic and Tracheal Stenosis in Patients Without Tracheostomies

BACKGROUND: Cryotherapy is used in the endoscopic treatment of subglottic and tracheal stenosis (SGTS), though comparative data remain limited. METHODS: A retrospective chart review identified 49 patients with benign SGTS treated with standard endoscopic management or cryotherapy...

Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets

Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insufficient evidence for a biosphere. In parallel with biosignature detection, exoplanet life detection...
