Simultaneous Image Registration and Monocular Volumetric Reconstruction of a fluid flow [PDF]
, 2011 We propose to combine image registration and volumetric reconstruction from a monocular video of a draining off Hele-Shaw cell filled with water. A Hele-Shaw cell is a tank whose depth is small (e.g. 1 mm) compared to the other dimensions (e.g.

Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming
Advanced Materials, Volume 38, Issue 32, 8 June 2026.Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

Experimental and Computational Investigation of an “Open” Transonic Cavity Flow [PDF]
, 2009 This paper presents an investigation of a transonic flow (M∞ = 0.85) over a rectangular cavity having a length-to-depth ratio of 5. Velocities were measured inside the cavity on the central plane and two off-centre planes using a two-component particle ...

Engineering Stealth Properties of Fluorescent Polymeric Nanoparticles by Short‐Chain Polysarcosine
Aggregate, Volume 7, Issue 6, June 2026.To define the minimal polysarcosine chain length required for nanoparticle stealth properties, we engineered dye‐loaded polymeric nanoparticles functionalized with 5‐, 11‐, or 19‐mer peptoids. Only nanoparticles with 19‐mer polysarcosine achieved near‐neutral zeta potential, suppressed nonspecific interactions with glass surface and live cells ...

Annalen der Physik, Volume 538, Issue 6, June 2026.This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

Low Reynolds Number Flow in a Packed Bed of Rotated Bars
Chemical Engineering &Technology, Volume 49, Issue 6, June 2026.Research Article: This study examines gas flow in a modular packed‐bed reactor with square bars arranged in rotated layers, creating complex void spaces. Using particle image velocimetry, measurements were taken at Reynolds numbers of 100 and 200. These results validated two particle‐resolved numerical simulations employing boundary‐conforming meshing ...
