Electron Phase Space Densities in Geostationary Orbits as Measured With GK2A, GOES‐16, and GOES‐17 Satellites

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study investigated electron phase space densities (PSDs) in geostationary orbits using data from Korea's geostationary satellite, GK2A, as well as GOES‐16 and GOES‐17 satellites. The PSDs were computed from electron fluxes measured by each satellite during a geomagnetically quiet period as defined by stringent conditions on geomagnetic ...

Using Machine Learning to Generate a GISS ModelE Calibrated Physics Ensemble (CPE)

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract A neural network (NN) surrogate of the NASA GISS ModelE atmosphere (version E3) is trained on a perturbed parameter ensemble (PPE) spanning 45 physics parameters and 36 outputs. The NN is leveraged in a Markov Chain Monte Carlo (MCMC) Bayesian parameter inference framework to generate a second posterior constrained ensemble coined a ...

Data‐Driven Transfer Functions From Differential Magnetometer Measurements to Enhance GIC Model Validation Capability: A Case Study in the Spanish Power Grid

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Geomagnetically induced currents (GICs) are unwanted currents flowing in long grounded conductors because of space weather phenomena. Example GICs are those flowing in power transmission lines via grounded transformer neutrals. Prediction models, used to foresee the amplitudes and waveforms of those currents and to identify weak points in ...

Geomagnetically Induced Currents, Transformer Harmonics, and Reactive Power Impacts of the Gannon Storm in May 2024

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Geomagnetically induced current (GIC) measurements made at two 3 phase, 3 limb transformers, operating in the Halfway Bush substation in Dunedin, New Zealand have been analyzed during the May 2024 Gannon Storm. GIC measurements were combined with very low frequency radio wave AC harmonic measurements made nearby, and reactive power ...

Epigenetic age acceleration predicts subject‐specific white matter degeneration in the human brain

Aging Cell, Volume 24, Issue 4, April 2025.
By isolating subject‐specific axonal regions “lesioned” by crossing through a WMH, age‐adjusted GrimAge was also able to predict longitudinal development of similar patterns of neuronal decline throughout the brain. This study is the first to demonstrate WMH lesionometry as a subject‐specific precision imaging technique to study degeneration in aging ...

Distribution and Diversity of Coastal Fish in Fresh and Oligohaline Waters: An Example of the Largest Baltic Sea Estuary of the Neva River

Ecology of Freshwater Fish, Volume 34, Issue 2, April 2025.
ABSTRACT Understanding how low salinity gradients (0‰–5‰) influence fish life cycles is critical for clarifying principles of fish assemblage formation in estuarine ecosystems. This study is intended to provide a foundation for predicting changes in fish populations amidst ongoing surface salinity decreases in the Baltic Sea. In the Neva River Estuary,

Non‐Native Species Abundance Decreases the Co‐Occurrence Between Native and Non‐Native Species Through Time at Any Phylogenetic Distance

Ecology Letters, Volume 28, Issue 4, April 2025.
We investigate how non‐native species can impact native species in a 30‐year time scale by estimating the co‐occurrence between native and non‐native species pairs. We show that interannual variability of non‐native species abundance could be more important than long‐term abundance trends in determining the effects of non‐native species through time ...

Assessing the Health Implications of UV/LED Nail Lamp Radiation Exposure During Manicure and Pedicure Procedures: A Scoping Review

International Journal of Dermatology, Volume 64, Issue 4, Page 659-666, April 2025.
ABSTRACT Skin malignancies associated with radiation exposure, notably malignant melanoma and keratinocyte carcinoma, are emerging as a significant global health challenge. While indoor tanning beds are associated with skin cancer risk, limited research exists on ultraviolet (UV)/light‐emitting diode (LED) nail lamps used widely in manicures/pedicures.
