Chance-Constrained Autonomous Spacecraft Formation Reconfiguration and Rendezvous with Passive Abort Safety

This paper addresses fuel-efficient maneuver planning under uncertainty for spacecraft relative motion in low-Earth orbits with passive safety using relative orbital elements (ROE) framework. We adopt a chance-constrained optimal control formulation that explicitly incorporates o...

Hidden or undetected? Quantifying the boundary between structural bias and statistical noise in peer review

Purpose Peer review shapes not only the evaluation of scientific claims but also whose work gains visibility and influence. A growing body of evidence shows that review outcomes can mirror structural inequities tied to authors' identities, language backgrounds, institutional posi...

Phospholipase Fluorogenic Probes and Molecular Determinants of Cyclic Guanosine Monophosphate–Adenosine Monophosphate Binding to Cyclic Oligonucleotide-Based Antiphage Signaling System CapV

Cyclic oligonucleotide-based antiphage signaling systems (CBASS) protect bacteria from bacteriophage infection by producing cyclic nucleotide second messengers that activate downstream effector proteins. Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP)-activated pho...

Oxygen Vacancy Engineering for Enhanced Remanent Polarization and Memory Window in a-IGZO/HZO Ferroelectric Field-Effect Transistors

Abstract HfO2-derived ferroelectric field-effect transistors (FeFETs) are promising for nonvolatile memory and logic-in-memory applications owing to CMOS compatibility and low-voltage polarization switching. Amorphous InGaZnO (a-IGZO) is attractive for back-end-of-line compatible...

Capturing Thermal and Hydrodynamic Heterogeneity in Polymorphic Crystallization Scale-Up via Physics-Inspired Multicompartmental Population Balance Models

Abstract Scaling up crystallization processes is notoriously difficult for polymorphic systems, where spatial heterogeneities in temperature and hydrodynamics dictate nucleation, growth, agglomeration, and solid-form selection. Conventional population balance models (PBMs) genera...

Trust dynamics among aquaculture producers and regulators in the midwestern United States

This qualitative study explores the relationship between producers and regulators in aquaculture production in the midwestern United States. We use the trust ecology framework to illustrate both how different dimensions of trust are present among aquaculture producers and how the...

Anion‐Driven Solvent Degradation Networks in High‐Concentration Battery Electrolytes

ABSTRACT High‐concentration electrolytes (HCEs) are investigated for their ability to form robust, inorganic‐rich solid electrolyte interphases (SEI). While the SEI composition in HCEs differs from that in dilute electrolytes, the specific anion‐mediated reaction network driving...

Precision Engineered 3D Multilayered Copper–Polymer Microstructures through Integrated Framework Fabrication

Abstract 3D multilayered conductive microstructures are essential for advanced electronic materials, heterogeneous integration, and next-generation interconnect architectures. However, fabricating high-fidelity multilayered metallic composites remains challenging due to the limit...

Characterization of Carboxymaltose Structure and Interactions with the Iron Core in Ferric Carboxymaltose (Injectafer) Using NMR Spectroscopy

Abstract Ferric carboxymaltose (FCM), marketed as Injectafer, is an intravenous iron formulation used to treat iron deficiency. It is composed of polynuclear Fe(III)-oxyhydroxide/oxide cores surrounded by carboxymaltose. Although it has been on the market for over 10 years, the s...

Impact of Backbone Fluorination on Self-Assembly and Mixed Conduction of Isoindigo-Based Polymers

Abstract Fluorination is a common method to induce backbone planarity in semiconducting polymers via noncovalent interactions that effectively lock the rotation of single bonds along the backbone. Often explored in dry-state devices, fluorination of isoindigo polymer backbones in...

Constraining Dust Formation in the Superluminous Supernova 2017gci with JWST Observations

Abstract We present JWST/MIRI observations of the Type I superluminous supernova (SLSN) 2017gci obtained over 2000 rest-frame days after the supernova (SN) exploded, which represent the latest phase images taken of any known SLSN to date. We find that archival Wide-field Infrared...

Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics

The next generation of particle physics experiments will face an era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environments and operational constraints. Harnessing these data for scientific discovery demands real-time infere...

Consumer welfare effects of banning hemp-derived THC beverages

Abstract A recent federal policy will close a regulatory loophole created by the 2018 Farm Bill and restrict the sale of intoxicating hemp-derived tetrahydrocannabinol (THC) beverages in the United States. Given the sector’s popularity among U.S. adults, it is useful to quantify...

Local approximations of global Hamiltonian from inclusion of algebras

A bstract We write down the global Hamiltonian of conformal field theory (CFT) in finite volume in terms of the modular Hamiltonian of the vacuum reduced to a local ball-shaped region, and use it to propose local approximations to the global Minkowski Hamiltonian in quantum field...

Heterogeneous beliefs, asset prices, and business cycles

We develop a complete-market production economy in which heterogeneous beliefs about productivity growth affect both asset prices and real activity. Firms must hire workers before productivity is realized, so operating leverage increases the exposure of profits to productivity ri...

Applying the MANifest Health Theory to Male Firefighter Lifestyle: A Conceptual Review Using the FANTASTIC Lifestyle Assessment

Firefighters face substantial long-term health risks related to cardiovascular disease, sleep disruption, occupational stress, inconsistent preventive care, and lifestyle behaviors shaped by fire-service culture. Although firefighter health research has traditionally emphasized a...

The Use of Generative Artificial Intelligence by Psychology Graduate Students in the United States

Background Although developed only recently, generative artificial intelligence (AI) applications for everyday use (e.g., ChatGPT) have become part of university life. The academy must navigate AI use in graduate education within several domains (coursework, teaching, research, c...

Magnetically Actuated Microrobot for Drug Delivery: Current Progress and Challenges

Magnetically actuated microrobots have emerged as promising wireless platforms for targeted drug delivery, offering active navigation, deep‐tissue accessibility, and externally programmable therapeutic release at length scales inaccessible to conventional medical devices while re...

Chiral Analysis of 2-Hydroxyglutarate in IDH-mut Glioma Tissue using the Kinetic Method

Abstract In almost all biological systems, stereochemistry is an important aspect of the molecular structure. Aberrant molecular geometry can be a reflection of the disease state which is then manifested through effects on cellular metabolism. A well-known example occurs in isoci...

An Integrated Processing–Performance Modeling Framework for Predicting the Effect of Curing on the Transverse Strength of Thermoset Composites

The mechanical properties of fiber-reinforced polymer matrix composites are strongly influenced by manufacturing processes. In particular, curing of thermoset polymer matrices introduces residual stresses that can significantly affect microscale damage initiation and the transver...
