InSAR-derived seasonal subsidence reflects spatial soil moisture patterns in Arctic lowland permafrost regions [PDF]
The CryosphereThe identification of spatial soil moisture patterns is of high importance for various applications in high-latitude permafrost regions but challenging with common remote sensing approaches due to high landscape heterogeneity.

Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Advanced Materials Interfaces, EarlyView.As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

The valuations of the near polygon G\(_{n}\)
Electron. J. Comb., 2009 The author classifies the valuations of the near polygon \(\mathbb{G}_n\). A \textit{near polygon} is a point-line incidence geometry such that two points determine at most one line, and for each point \(p\) and line \(L\), there is a unique point on \(L\) nearest to \(p\) in the point collinearity graph.

The Universal Embedding of the Near Polygon ${\Bbb G}_n$ [PDF]
The Electronic Journal of Combinatorics, 2007 In an earlier paper, we showed that the dual polar space $DH(2n-1,4)$, $n \geq 2$, has a sub near-$2n$-gon ${\Bbb G}_n$ with a large automorphism group. In this paper, we determine the absolutely universal embedding of this near polygon. We show that the generating and embedding ranks of ${\Bbb G}_n$ are equal to ${2n \choose n}$. We also show that the
