The Effect of Intrinsic Alignments on Weak-lensing Statistics in Hydrodynamical Simulations

open access: yesThe Astrophysical Journal
The next generation of weak-gravitational-lensing surveys has the potential to place stringent constraints on cosmological parameters. However, their analysis is limited by systematics such as the intrinsic alignments of galaxies, which alter weak ...

Step‐Ladder Bioprinting to Align Collagen Fibers for Anisotropic Tissue Fabrication

open access: yesSmall, Volume 22, Issue 13, 3 March 2026.
The step‐ladder printing platform includes successive segments of channels with varying widths in a custom barrel design. This design allows for improved anisotropy of collagen fibers during extrusion. To demonstrate its effectiveness, corneal constructs with high transparency and shape fidelity, as well as articular cartilage constructs, displaying ...

A Scalable Gaussian Process Approach to Shear Mapping with MuyGPs

open access: yesThe Astrophysical Journal
Analysis of cosmic shear is an integral part of understanding structure growth across cosmic time, which in turn provides us with information about the nature of dark energy.

Inferring Cenozoic Cover Thickness and Bedrock Sedimentary Material in 3D From Geophysical Data Using Machine Learning Algorithms: A Case Study in the Lockington Region, Victoria, Australia

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This study presents a supervised machine learning approach to constructing a 3D geological model for the Lockington area in Victoria, Australia, by integrating borehole observations, geophysical surveys (magnetic, gravity, and radiometric), and elevation data.

Stress and Strain in Magma‐Mush Reservoirs: Implications for Reservoir Failure and Magma Propagation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Investigating the mechanical stability and failure of magma reservoirs following magma supply is critical for volcanic hazard assessment. While magma reservoirs were traditionally modeled as melt‐filled cavities, they are now more often described as crystal mushes where melt flows and is stored in porous networks.

A New Method for PSF correction using the Ellipticity of Re-smeared Artificial Images in Weak Gravitational Lensing Shear Analysis

open access: yesThe Astrophysical Journal, 2014
We propose a new method for Point Spread Function (PSF) correction in weak gravitational lensing shear analysis using an artificial image with the same ellipticity as the lensed image. This avoids the systematic error associated with the approximation in PSF correction used in previous approaches.

Longitudinal Mean Velocity and Turbulent Kinetic Energy Within an Emergent Canopy in Nonuniform Flows

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Vegetation‐induced drag generates nonuniform water surface profiles through flow disruption, creating complex hydrodynamic conditions characterized by enhanced turbulence and energy dissipation. This study investigates the longitudinal velocity and turbulent kinetic energy (TKE) dynamics in emergent canopies under streamwise varying flow ...

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

open access: yesAdvanced Science, Volume 13, Issue 10, 18 February 2026.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.

Weak Gravitational Lensing around Low Surface Brightness Galaxies in the DES Year 3 Data

open access: yesThe Open Journal of Astrophysics
We present galaxy-galaxy lensing measurements using a sample of low surface brightness galaxies (LSBGs) drawn from the Dark Energy Survey Year 3 (Y3) data as lenses.
