Vigilant Algorithms and the Contagion of Risk in Automated Opioid Risk Assessment
Amid the ongoing opioid crisis, U.S. health systems have extended prescription monitoring interfaces with proprietary reports that provide clinicians with algorithmic risk scores to guide opioid decisions. However, little is known about how such tools shape clinical encounters, p...

Calculation of Planck's Constant from the Electric Charge of the Photonic Etheron
The present work demonstrates that the Planck constant is not a merely empirical parameter, but derives directly from the dynamical structure of the photon described by the MODEC (Double-Helical Model of the Photon) [1], and specifically from the electric charge modulus of the tw...

Abstract Julio R. Contreras (1933–2017) was an Argentinian naturalist who dedicated a great part of his life in the study of the genus Ctenomys (Rodentia, Ctenomyidae), particularly in Argentina and Paraguay, describing several new species. In this paper we complement the taxonom...

Ophthalmic manifestations of MAB21L2 mutation: A case report
Introduction: This report is to describe the clinical presentation, ophthalmic findings, and multimodal evaluation of a child with severe bilateral microphthalmia and coloboma associated with a MAB21L2 variant. Case Report: A 3-year-old girl presented with bilateral small eyes an...

Children With Complex Chronic Conditions in the Child Protective Services
OBJECTIVES: Little is known about the prevalence and outcomes for children with complex chronic conditions (CCCs) in the Child Protective Services (CPS) system. We aimed to determine the prevalence and associations of CCC designation across CPS outcomes and years among a group of...

Structural variants (SVs) in the human genome play an important role in health and disease. Identification of SVs is commonly performed using short-read sequencing. However, because sequenced fragments are typically shorter than the variants themselves, accurate SV calling remain...

Abstract Background Coexisting maternal and child undernutrition (CMCU) is a critical aspect of intergenerational malnutrition. The evidence on its epidemiological trends and spatial distribution remains limited in Nepal. This study investigated the temporal trends, determinants,...

Writing Identity and Self-Efficacy in Early Childhood Across Home and School Contexts
Abstract Early writing development involves more than acquiring transcriptional skills; it is closely bound up with the emergence of children's identities as writers and their beliefs in their own capacity to write. Drawing on sociocultural theory and social cognitive theory, thi...

Version 2: The Ever-Existing Nature of Space – The Permanent Framework of the Universe
Abstract: This section proposes an ontological framework in which space is regarded as the primary, ever-existing, and unbounded entity, fundamentally distinct from the observable universe and its transient contents. While modern cosmology successfully describes the evolution of...

Background: Sarcopenia is highly prevalent in patients with end-stage renal disease and is associated with adverse outcomes. We evaluated the diagnostic accuracy of rectus femoris ultrasound, compared with bioimpedance spectroscopy (BIS), for identifying sarcopenia defined by the...

Intensity-StableWavelength Tuning in InGaN/GaN MultipleQuantum Wells
Abstract Dynamic tuning of emission from III-nitride multiple quantum wells (MQWs) without significant intensity variation is a highly desirable feature as the emission wavelength from MQWs is generally fixed. This work demonstrates a three-terminal InGaN/GaN field-effect light-e...

Surgery Utilization Mediates Survival in Patients With Dementia and Stage I– III Colorectal Cancer
BACKGROUND: Dementia is associated with increased mortality among patients with colorectal cancer (CRC), and they receive less invasive evaluations, chemotherapy, and surgery. The objectives of this study were to (1) compare demographics and treatment patterns among individuals w...

Abstract. Changes in active layer thickness (ALT) are used as an indicator of permafrost degradation. Increases in ALT can lead to increased greenhouse gas emissions, altered hydrology and ecology, ground instability, and a positive climate feedback. Quantifying ALT spatial heter...

Abstract A family of iron complexes bearing iminopyridine (ImPy) ligands with systematic variations on the N ‐aryl and pyridine moieties was evaluated as pre‐catalysts for the coordinative polymerization of β‐myrcene and butadiene. Upon activation with Al i Bu 3 and trityl borate...
