Linking public and private neuroimaging data with decentralized analysis via NeuroFLAME Vaults

Large-scale datasets and global collaborations are increasingly enabling exciting discoveries in neuroimaging research; however, barriers such as data privacy regulations and unequal access to computational infrastructure continue to hinder progress. Federated analysis offers a p...

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...

Generative Modeling by Minimizing the Wasserstein-2 Loss

Abstract. This paper develops a generative model by minimizing the second-order Wasserstein loss (the [Formula: see text] loss) through a distribution-dependent ordinary differential equation (ODE), whose dynamics involves the Kantorovich potential associated with the true data d...

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...

Chirality-induced magnetoresistance in hybrid organic-inorganic perovskite semiconductors

The combination of semiconducting properties and synthetically tunable chirality in chiral metal halide semiconductors (CMHSs) offers a compelling platform for room temperature control of electronic spin properties, leveraging effects such as chirality-induced spin selectivity (C...

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...

It's about time: Specific and unspecific effects of episodic future thinking on farsighted decisions

Humans tend to discount the value of delayed rewards. As a consequence, they forego larger long-term benefits (e.g., €29 in 91 days) in favor of smaller short-term gains (e.g., €20 now). Episodic future thinking (EFT) attenuates such delay discounting. That is, people are more li...

A firefly-inspired model for detecting the alien

The Search for Extraterrestrial Intelligence (SETI) has historically been a search for aliens like us, shaped by human-centric ideas of intelligence, communication, and technology. However, humans are not the only instance of an intelligent, communicating species on Earth, and th...

A Compensated Structure‐Function Approach to Measuring TKE Dissipation in the Atmospheric Boundary Layer

Abstract Despite the importance of turbulence measurements to atmospheric dynamics and modeling, developing objective, accurate schemes to estimate TKE dissipation ε from velocity time‐series has proven elusive. Objective schemes can be automated, as needed for large data sets ge...

Reformulating Time-Cure Superposition to Describe the Phase Transition in Rearranging Gel Networks

Abstract Rearranging hydrogels are used for applications that require tailored control of solid- and liquid-like properties. These applications necessitate pinpointing the phase transition, where a sample-spanning structure is formed or broken. To characterize the mechanical prop...

Who Can Afford to Fail? Investigating Science Students' Perceptions of Failure Through the Lens of Their Identities

ABSTRACT Scientists agree that learning to cope with failures is an important skill for science students to develop, and students who participate in science research often have positive outcomes after coping with science failures. However, the experience of failure in undergradua...

Resolving Convective‐Scale Cloud and Precipitation Structures in Tropical Cyclone Rainbands With Novel Raman Lidar Observations

Abstract Low‐level clouds in the tropical cyclone (TC) rainbands modulate the radial inflow of warm, moist boundary layer air, which can impact TC intensity. Yet, precisely measuring rainband cloud boundaries with existing remote sensing techniques remains a challenge. To address...

A standardized SBML/PRISM benchmark library for stochastic model checking in synthetic biology

Stochastic model checking is a powerful verification technique used in engineering to assess system reliability and correctness. Many synthetic biological systems, including chemical reaction networks, can be modeled as stochastic processes, making stochastic model checking well...

Morphology‐Driven Ternary Pattern Space Spans Shallow Marine Clouds

Abstract Marine shallow clouds exhibit a variety of patterns, which have been the subject of extensive research. In this study, we introduce a new approach for their continuous classification using Moderate Resolution Imaging Spectroradiometer (MODIS) true color imagery. This met...

Functionally active lymphoid aggregates correlate with improved prognosis in brain metastases

Abstract B cells and their cellular neighborhoods, i.e., lymphoid aggregates (LAs) and tertiary lymphoid structures (TLS), have not been extensively studied in melanoma brain metastases (BM) or lung adenocarcinoma (LUAD) BM, despite their prognostic value and role in immunotherap...

Weak-Form Learning for Mean-Field Partial Differential Equations: An Application to Insect Movement

Abstract. Insect populations subject to epidemic infection, predation, and anisotropic environmental conditions may exhibit preferential movement patterns. Given the virtually random nature of the exogenous factors driving these patterns over short timescales, individual insect t...

Evidence for endemism and local adaptation in Antarctic soil bacteria

Antarctic soils represent one of the more extreme environments for microbial life on Earth, yet they harbor heterogeneous and diverse microbial communities. Biologists have long hypothesized that Antarctic microorganisms are unique from those found on other continents due to the...

An Experience-Sampling Approach to Examining Cortisol and Testosterone Profiles in Bipolar and Depressive Mood Disorders

Emotion dysregulation is a core component of bipolar disorder (BD). However, there is a critical gap concerning the measurement of emotion-relevant neuroendocrine processes in this population. The present investigation examined neuroendocrine profiles (i.e., cortisol and testoste...
