A Synovium‐on‐Chip Platform to Study Multicellular Interactions in Arthritis
Advanced Healthcare Materials, EarlyView.The Synovium‐on‐Chip comprises a thin microporous PDMS membrane to support co‐culture of fibroblast‐like synoviocytes (FLS), THP‐1‐derived macrophages, and endothelial cells, enabling real‐time analysis of synovial‐vascular interactions. FLS migration through the pores drives endothelial remodeling, while TNF‐α stimulation induces robust inflammatory ...

Journal of Combinatorial Theory, Series A, 2000 An orthogonal space \(O^+_8(q)\) is a pair \((V,Q)\) such that \(V\) is a vector space of dimension 8 over \(GF(q)\) and \(Q:V\to GF(q)\) is a nondegenerate quadratic form of hyperbolic type. An ovoid \(O\) of \(O^+_8(q)\) is a set of \(q^3+1\) singular points of \(O_8^+(q)\) such that every maximal totally singular subspace contains just one point of \

Advanced Healthcare Materials, EarlyView.Wound closure is governed by geometry‐orientation coupling: aligned fibers speed migration along their axis but hinder perpendicular advance. In vivo diabetic wound experiments with composition‐matched fibrin, combined with an anisotropic diffusion (biased random‐walk) model, quantify this trade‐off and generate a healing landscape.

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia
Advanced Healthcare Materials, EarlyView.This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

Advanced Healthcare Materials, EarlyView.A superhydrophobic 3D cell culture platform enables rapid and consistent formation of heterotypic tumor–stroma clusters, and reveals how physiological shear conditions influence metastatic signaling. Mechanical stimulation of cancer‐associated fibroblasts promotes sustained cytokine secretion and survival‐promoting pathways, showing how multicellular ...

A Class Of Ovoidal Laguerre Planes
Communications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1979 We replace in the parabolic model of the classical Laguerre plane the parabolas y = a + b X 4- c by the polynomial curves y î= ax® + b x“ + c. Where n and m are even and odd integer^, respectively. Por each siieh a pair n, m with n>m>0 ‘we obtain ’agaijı a Lagtıerre plane wlıicb is also ovoidal.

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications
Advanced Materials, EarlyView.Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.
