Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

MaX4Zero: Masked Extended Attention for Zero‐Shot Virtual Try‐On In The Wild

Computer Graphics Forum, EarlyView.
Max4Zero is a zero‐shot, training‐free virtual try‐on method that leverages diffusion priors and extended attention for accurate garment transfer. By warping reference garments and mitigating texture sticking, it achieves superior fidelity, garment preservation and identity consistency over state‐of‐the‐art methods without additional training ...

An object-based region-growing phase unwrapping method for mapping vertical displacement in permafrost landscapes

International Journal of Applied Earth Observations and Geoinformation
Terrain displacement due to the seasonal thaw of the active layer above permafrost can be sensitive to climate change; however, its accurate characterization remains a challenge.

TABI: Tight and Balanced Interactive Atlas Packing

Computer Graphics Forum, EarlyView.
Abstract Atlas packing is a key step in many computer graphics applications. Packing algorithms seek to arrange a set of charts within a fixed‐size atlas with as little downscaling as possible. Many packing applications such as content creation tools, dynamic atlas generation for video games, and texture space shading require on‐the‐fly interactive ...

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

Feasibility of ALOS2 PALSAR2 Offset-Based Phase Unwrapping of SAR Interferogram in Large and Complex Surface Deformations

IEEE Access, 2018
The interferometric synthetic aperture radar (InSAR) is a well-known tool for mapping ground surface deformations with centimeter precision, and is much better than that used in the offset tracking method.

4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...

AI-Based 2D Phase Unwrapping Under Rayleigh-Distributed Speckle Noise and Phase Decorrelation

Photonics
Phase unwrapping is a critical step in interferometric imaging modalities such as holography and synthetic aperture radar, yet conventional analytical algorithms struggle in low signal-to-noise and high-speckle environments.
