Lunar Formation by Triple Phase Transition in the Differentiating Proto-Earth
This work proposes a theory of lunar formation grounded in a thermodynamic necessity: any planet of terrestrial mass emerges from accretion in a state of near-total silicate mantl…
Phase-Mediated Attractor Dynamics in Millisecond Pulsar Timing Residuals
I present a phase-space analysis of NANOGrav 15-year millisecond pulsar timing residuals using Phase-Mediated Attractor Dynamics (PMAD). By constructing cosine-delta sequences fro…
THE SABNE FRAMEWORK v33.0: A DUAL-PERTURBER KINEMATIC RESOLUTION TO THE PLANET 9 ANOMALY AND SOLAR OBLIQUITY
Current statistical frameworks and Nbody simulations investigating Extreme Trans-Neptunian Object (ETNO) clustering frequently assume a single massive perturber, introducing an in…
An improved approach to identifying tropical cyclones in model data using the cyclone phase space: warm core, symmetric…
A method for identifying tropical cyclones (TCs) from cyclone tracks is introduced which is based solely on the physical structure of the cyclone and not tuned to maximize the mat…
Supersaturation dynamics govern crystallographic orientation inheritance during mineral nucleation: insights from aqueo…
Crystal nucleation kinetics exert a primary control on rock microstructure, phase distribution, and how close to equilibrium mineral reactions proceed. In multiphase systems, epit…
A Comprehensive analysis of High-Resolution VHF Observations with LOFAR of the Positive Initiating Event for Lightning
Decades of observations inside thunderclouds have failed to measure electric fields large enough to spontaneously initiate a spark. The initiation process of lightning is thus an …
Accurate hourly precipitation estimation in observation-sparse regions through explainable multi-source learning and cr…
Accurate and timely precipitation information remains difficult to obtain in regions affected by sparse observations, radar limitations, and product latency. Here we present XTPre…
Ensemble-Based Parameter Estimation for an Unconfined Groundwater Model of a Small Island Considering Tidal Overheight
Tidal influences are rarely considered in parameter estimation procedures for coastal groundwater flow models. Yet, considering tides adds to the already high computational burden…
Impact of Mineral Spatial Distribution on CO2 Dissolution Rates in Multimineral Carbonate Rocks
Understanding the reactive dissolution of carbonate rocks in CO2-rich brine environments is critical for optimizing carbon capture and storage (CCS). This study integrates flow ex…
The reservoir lotic-lentic boundary represents a hotspot of dissolved organic matter
Dissolved organic matter (DOM) plays an essential role in freshwater ecosystem functioning, motivating the need to understand how DOM changes across ecosystem gradients. Reservoir…
Paleorotation Anomalies and the Secondary Satellite Hypothesis: Quantitative Support for Rotational Predictions of the …

Vertical Array Distributed Acoustic Sensing for waterborne acoustic signals up to 3 kHz
Distributed Acoustic Sensing (DAS) has become a widely used passive acoustic monitoring method but faces challenges recording above a few hundred hertz. Implementing DAS for highe…
The Proton-Alpha Instability as a Source of Ion Heating at Earth's Bow Shock
Electrostatic waves are frequently observed at collisionless shocks and are believed to play a key role in energy dissipation. Recent spacecraft observations have identified a pro…
Extraterrestrial Chemical Boundary Conditions and Evolutionary Opportunity Space on Early Earth
Extraterrestrial material has usually been treated as delivered cargo: amino acids, nucleobases, organics, brines, or biological vectors. A boundary-condition approach asks a diff…
