Multishot Compressive Hyperspectral Imaging Based on Tensor Fibered Rank Minimization and Its Primal-Dual Algorithm

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Coded aperture snapshot spectral imaging (CASSI) compresses tens to hundreds of spectral bands of the hyperspectral image (HSI) to a 2-D compressive measurement.

Modeling Physical Activity Profiles in COPD Patients: A Basis Expansion Approach to Variable Domain Functional Regression Models

Biometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT Physical activity plays an important role in the well‐being of patients with Chronic Obstructive Pulmonary Disease (COPD). The telEPOC program, developed at the Galdakao‐Usansolo University Hospital (Vizcaya, Spain), provided a telemonitoring data set resulting in a variable domain functional data set.

A Tensor-Based Subspace Approach for Bistatic MIMO Radar in Spatial Colored Noise

Sensors, 2014
In this paper, a new tensor-based subspace approach is proposed to estimate the direction of departure (DOD) and the direction of arrival (DOA) for bistatic multiple-input multiple-output (MIMO) radar in the presence of spatial colored noise.

Tensor-based color image decomposition in an advanced hybrid IWT-SVD framework for digital watermarking

Franklin Open
This paper presents a robust color image watermarking scheme based on Tensor Singular Value Decomposition (Tensor-SVD). This is designed to effectively exploit the strong inter-channel correlation of RGB color images. By modelling the RGB components as a

Multimodal Characterization of APOE ε4‐Associated Neurovascular Heterogeneity Using Retinal, Plasma, and Neuroimaging Biomarkers in Alzheimer's Disease

CNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
The LASSO and logistic regression model integrate neuroimaging measures and retinal vascular biomarkers to identify key predictors of APOE ε4 status, improving genotype‐specific stratification. The model's calibration curve and decision curve analysis demonstrate improved discrimination and clinical utility when retinal vascular data are integrated ...

Growth of White Matter Signal Aberrations and Cortical Changes in Men and Women: A 9‐Year Multiple‐Time‐Point Longitudinal MRI Study in Older Adults

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
Greater growth of white matter signal aberration (WMSA) volume, the most common age‐related finding on brain MRI, is connected to increased cortical thinning, more so in men than women. In men only, the cortical regions experiencing increased thinning due to WMSA growth displayed a concomitant cortical area expansion.

A Time‐Continuous Model of the 3D Ionospheric Current System and Associated Magnetic Fields in the Diurnal Variation Band

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ionospheric currents and their associated magnetic perturbations are difficult to predict due to the high variability of their driving mechanisms. In addition, the 3D structure of the currents is challenging to unravel due to the lack of direct observations within the current flow region, particularly in the E $E$‐layer.

Episodic Seismicity Bursts Driven by Magma Intrusion During the 2025 Santorini‐Amorgos Seismic Crisis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The 2025 Santorini–Amorgos seismic crisis in Greece had an exceptionally large number and sustained rate of moderate‐sized earthquakes. We used a machine‐learning‐based earthquake monitoring workflow to detect and relocate 66,109 earthquakes and interpret the results in the context of global analogs.

Lower serum uric acid and impairment of right cerebral hemisphere structural brain networks are related to depressive symptoms in cerebral small vessel disease: A cross-sectional study

Heliyon
Cerebral small vessel disease (SVD) may be associated with an increased risk of depressive symptoms. Serum uric acid (SUA), an antioxidant, may be involved in the occurrence and development of depressive symptoms, but the mechanism remains unknown ...
