An elementary proof that rationally isometric quadratic forms are isometric [PDF]
Archiv der Mathematik, 2014 Let $R$ be a valuation ring with fraction field $K$ and $2\in R^\times$. We give an elementary proof of the following known result: Two unimodular quadratic forms over $R$ are isometric over $K$ if and only if they are isometric over $R$. Our proof does not use Witt's Cancelation Theorem and yields an explicit algorithm to construct an isometry over $R$

Isometric embeddings of graphs [PDF]
Proceedings of the National Academy of Sciences, 1984 We prove that any finite undirected graph can be canonically embedded isometrically into a maximum cartesian product of irreducible factors.

Advanced Science, EarlyView.We present the MyoRobot 3.0, an advanced platform that combines high‐resolution imaging with automated mechanical testing to improve the accuracy of single muscle fibre analysis. The system tracks fibre diameter changes during stretch, preventing major stress miscalculations.

Isometric and quasi-isometric weighted composition operators
The Journal of AnalysisIn this paper we characterize $m$-isometric and quasi-$m$-isometric weighted composition operators on the Hilbert space $L^2(μ)$. Also, we find that normal-$m$-isometry and normal quasi-$m$-isometry weighted composition operators have finite spectrum. Consequently we have the results for composition and multiplication operators.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis
Advanced Science, EarlyView.In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

On deformations of spherical isometric foldings [PDF]
, 2009 summary:The behavior of special classes of isometric foldings of the Riemannian sphere $S^2$ under the action of angular conformal deformations is considered. It is shown that within these classes any isometric folding is continuously deformable into the
