Understanding Relative Reactivity-Governed Kinetics and Network Formation in Thiol-Yne and Other Competitive Consecutive Polymerizations

Abstract Thiol-yne polymerizations couple two sequential additions of thiol: first, to an alkyne and subsequently, to a vinyl sulfide, making the polymerization and the resulting polymer structure dependent on the relative reactivity. Herein, kinetic, analytical, and random-graph...

Controlled SiO2 etching by HF in an HF/H2O liquid-like layer in a vacuum environment

Controlled SiO2 etching was demonstrated using hydrogen fluoride (HF) in an HF/H2O liquid-like layer in a vacuum environment. Under vacuum conditions in the absence of H2O, there was no etching of SiO2 by HF. In the presence of H2O, the SiO2 etch rates were dependent on the HF pr...

The Fluid Mechanics of Stroke

Stroke remains a leading global cause of death and disability, originating from disruption of blood supply to brain tissue either from blockage or rupture of a blood vessel in the brain. Understandably, fluid mechanics plays a critical role in stroke mechanisms, disease manifesta...

Being and Being This: Haecceity and the Univocal Concept of Being in Duns Scotus

Abstract Haecceity is often understood as a theoretical construct posited by Duns Scotus to explain individuation. This characterization is flawed in two ways: first, it lends haecceity an ad hoc appearance and obscures the fact that it is called for by Scotus’s most basic philos...

“I see my body the way people see me”: A qualitative study on the acceptability and cultural adaptation of the mind.body.voice curriculum for Latina youth

Latina adolescents and emerging adults navigate conflicting appearance ideals, balancing the “Latina curvy ideal” with Eurocentric thinness standards that contribute to body dissatisfaction, disordered eating, and emotional distress. Few culturally tailored interventions have bee...

Caysichite-(Y) Ca4(Y,REE)4(Si8O20)(CO3)6·8H2O: Endmember Composition and Structure Established from New Occurrences Across Different Geologic Settings

Abstract The heavy rare earth element silicate-carbonate mineral caysichite-(Y) [Ca4(Y,REE)4(Si8O20)(CO3)6·8H2O] was discovered in the alkaline granite of the Golden Horn Batholith, near Washington Pass, Okanogan County, Washington, USA, as sub-millimeter euhedral orthorhombic pa...

For Molecular Polaritons, Disorder and Phonon Time Scales Control the Activation of Dark States in the Thermodynamic Limit

Abstract Collective light–matter systems host an extensive manifold of dark states whose role in the emergence of thermodynamic behavior remains poorly understood, especially in the presence of disorder and structured environments. Here, we develop a hybrid matrix product state–h...

Dependent reachable sets for the constant bearing pursuit strategy

This paper introduces a novel reachability problem for the scenario involving two agents, where one agent follows another agent using a feedback strategy. The geometry of the reachable set for an agent, termed dependent reachable set, is characterised using the constant bearing p...

Bridging Knowledge Gaps in Clinical AI: An Activity Theory Perspective on Interdisciplinary Data Work for Telehealth

Advanced AI technologies are increasingly integrated into clinical domains to advance patient care. The design and development of clinical AI technologies necessitate seamless collaboration between clinical and technical experts. However, such interdisciplinary teams are often un...

Bridging Minds and Machines: Mapping the Terrain of Communication in Human-AI Teams — A Systematic Literature Review

As AI becomes increasingly adept at communicating with humans in natural language and complementing human skills in various collaborative and teamwork settings, how the CSCW community understands the evolving role of communication in human-AI teams (HATs) urgently needs to keep p...

Seasonal to decadal evolution of firn properties and impacts on hydrology of the Juneau Icefield

Alpine glaciers of Alaska are significant contributors to global sea-level rise. Most Alaskan glaciers lose mass through surface melt due to increasing atmospheric temperatures. Surface melt may be retained or run off in the snow and firn, potentially altering regional glacial hy...

On the complexity of isomorphism problems for tensors, groups, and polynomials III: actions by classical groups

Abstract We study the complexity of isomorphism problems for tensors, represented in coordinates by multiway arrays, under natural actions by classical groups such as orthogonal, unitary, and symplectic groups. These problems arise naturally in statistical data analysis and quant...

When Responsibility Compensates for Ownership: Agency Theory, State Capitalism, and the Scale of Chinese OFDI

This paper investigates how the ownership structures of Chinese enterprises shape their outward foreign direct investment (OFDI) outcomes, and whether corporate social responsibility (CSR) performance alters that relationship. Drawing on agency theory and a firm-level panel datas...

Multi-season evaluation of temperature and wind in the marine boundary layer along the United States northeast coast in the High-Resolution Rapid Refresh model

The High-Resolution Rapid Refresh (HRRR) model is run operationally by the National Oceanic and Atmospheric Administration to provide high-resolution short-range forecasts for the continental United States. The evaluation of the HRRR model off of the United States coasts has been...

Chorus Wave‐Induced Ionospheric Variability

Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere. We in...

The Python simulations of chemistry framework: 10 years of an open-source quantum chemistry project

Over the past decade, the Python-based Simulations of Chemistry Framework (PySCF) has developed into a widely used open-source platform for electronic-structure theory and quantum chemical method development. This article reviews the major advances since the previous overview in...

Indicator Compliance in Bulk Water Does Not Reflect Biofilm-Associated Microbial Community Composition or Potential Risk in UV-C LED-Treated Rainwater Harvesting Systems

Abstract Rainwater harvesting (RWH) systems are increasingly used to supplement potable and nonpotable water supplies but remain understudied with respect to biofilm-associated microbial risk. This study used a pilot-scale, temperature-controlled pipe loop to investigate how pipe...

Spacecraft Relative Motion with Respect to a Spinning Chief Body Frame

Abstract Relative motion between orbiting spacecraft is commonly modeled in the Hill frame due to its analytical first-order solutions and the intuitive geometry of the resulting trajectories. However, the Hill frame is not ideal for mission scenarios involving constraints define...

Significant Reduction in Ethane Emissions in the Denver‐Julesburg Basin From 2015 to 2021 From Oil and Natural Gas Operations

Abstract Top‐down studies of methane (CH 4 ) emissions often use the average ethane‐to‐methane (C 2 /C 1 ) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH 4 sources (ruminants, wetlands, landfills, and other methanogenic sou...
