River Research and Applications, EarlyView.ABSTRACT Sloughs are slow‐moving or still water systems that serve as an important ecosystem component connecting rivers and floodplains such as the Apalachicola River in northwest Florida. However, sloughs of the Apalachicola River have become hydrologically disconnected from the mainstem due to the impact of failed navigation projects such as channel

Remote SensingLight detection and ranging (lidar) scanning tools are available that can make rapid digital estimations of biomass. Voxelization and convex hull are two algorithms used to calculate the volume of the scanned plant canopy, which is correlated with ...

Boundary Value Problems, 2010 The block-grid method (see Dosiyev, 2004) for the solution of the Dirichlet problem on polygons, when a boundary function on each side of the boundary is given from C2,λ, 0<λ<1, is analized.

Dynamic Polygon Clouds: Representation and Compression for VR/AR [PDF]
arXiv, 2016 We introduce the {\em polygon cloud}, also known as a polygon set or {\em soup}, as a compressible representation of 3D geometry (including its attributes, such as color texture) intermediate between polygonal meshes and point clouds. Dynamic or time-varying polygon clouds, like dynamic polygonal meshes and dynamic point clouds, can take advantage of ...

Near‐Infrared Emission Perovskites for Multifunctional Bioimaging
Small Science, EarlyView.Currently, the acquisition of information inside living organisms is highly dependent on a variety of photodetectors with different response ranges, for which a near‐infrared‐emitting perovskite material has been designed that exhibits excellent performance under both UV and X‐ray irradiation, enabling multimodal imaging of biological tissues with only

Virtual Element Methods on Meshes with Small Edges or Faces [PDF]
arXiv, 2017 We consider a model Poisson problem in $\R^d$ ($d=2,3$) and establish error estimates for virtual element methods on polygonal or polyhedral meshes that can contain small edges ($d=2$) or small faces ($d=3$).

Small Structures, EarlyView.Luminescent quantum‐confined perovskite nanocrystals self‐assemble into various superlattice shapes: rhombic, rectangular, and hollow frames. The self‐assembly conditions, nanocrystals, and superlattices are studied with optical and electron microscopies and X‐ray nanodiffraction to identify the origin of different shapes.

Interior penalty discontinuous Galerkin method on very general polygonal and polyhedral meshes [PDF]
arXiv, 2012 This paper focuses on interior penalty discontinuous Galerkin methods for second order elliptic equations on very general polygonal or polyhedral meshes. The mesh can be composed of any polygons or polyhedra which satisfies certain shape regularity conditions characterized in a recent paper by two of the authors in [17].
