An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

Advanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Self-Affine Tilings with Several Tiles, I

Applied and Computational Harmonic Analysis, 1999
A collection \(T_i \subseteq {\mathbb R}^d\), \(i=1, \ldots, M\), together with an expanding \(d\times d\) matrix \(A\), and a collection of sets \(\Gamma_{ij} \subseteq {\mathbb Z}^d\), \(i,j=1, \ldots, M\), is called \textit{self-affine} if \[ AT_i = \bigcup_{j=1}^M (\Gamma_{ij}+T_j), \;\;(i=1, \ldots, M) \] (the sets in the union above are assumed ...

Counting With Irrational Tiles [PDF]

, 2014
We introduce and study the number of tilings of unit height rectangles with irrational tiles. We prove that the class of sequences of these numbers coincides with the class of diagonals of N-rational generating functions and a class of certain binomial ...

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

Advanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

Performance Testing on Vector vs. Raster Map Tiles—Comparative Study on Load Metrics

ISPRS International Journal of Geo-Information, 2020
Recent developments in web map applications have widely affected how background maps are rendered. Raster tiles are currently considered as a regular solution, while the use of vector tiles is becoming more widespread.

Tile Count in the Interior of Regular 2n-gons Dissected by Diagonals Parallel to Sides [PDF]

, 2009
The regular 2n-gon (square, hexagon, octagon, ...) is subdivided into smaller polygons (tiles) by the subset of diagonals which run parallel to any of the 2n sides.

Bioengineered 3D hPSC‐Cholangiocyte Ducts With Physiological Signals for Biliary Disease Modeling

Advanced Healthcare Materials, EarlyView.
Tian and colleagues generated a bioengineered bile duct from human pluripotent stem cell (hPSC)‐derived intrahepatic cholangiocytes within a high‐throughput, 384‐well platform to systematically examine the influence of biliary physiological signals including fluid flow, stromal cells and bile acids, and models intrahepatic biliary disease progression ...

Deciphering the Role of Cancer Stem Cells in Breast Cancer Brain Colonization Using a Novel Patient‐Derived Model

Advanced Healthcare Materials, EarlyView.
This study shows that stem‐like cells isolated from breast cancer brain metastases drive the spread and growth of tumors in the brain. Among them, a highly adhesive subgroup initiates metastasis and resists many drugs. By closely reflecting patient tumors, these models help identify new targets and improve the development of effective treatments ...

L’Anjou : la tuile au pays de l’ardoise

Archéologie Médiévale
At the edge of both the Armorican Massif and the Paris Basin, the Anjou region is well known for its slated roofs. Though slate deposits are numerous and well stocked, other roofing materials have been used concurrently in restricted areas ...
