Toward precision oncology: An integrative multi‐omics approach for prognosis prediction and inferred immunotherapy responsiveness in breast cancer

Clinical and Translational Discovery, Volume 6, Issue 1, February 2026.
We integrated four omics to build a breast cancer immunotherapy predictor. Survival‐associated biomarkers were compressed into 200 latent features via an autoencoder, then refined using three survival models. K‐means defined two subgroups (C1, high‐risk and C2, low‐risk).

Novel Insights on Ocean Internal Waves: Quantitative Surface Manifestations and Upper Ocean Layer Displacements From the Surface Water Ocean Topography Mission (SWOT) Measurements

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave

Applying Hpo Indices to Empirical Thermospheric Density Models During Geomagnetic Storms

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Accurate atmospheric drag modeling is essential for precise orbit determination and prediction of Low Earth Orbit satellites. A key component is the thermospheric density, typically estimated using empirical models driven by geomagnetic activity indices such as the 3‐hr Kp or ap.

Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...
