Frankenplace, geospatial search, and discrete global grid systems

open access: yes, 2019
Quick note on Frankenplace, a cool search tool that displays the geographic distribution of documents that match the user's query as a heatmap. Details of how the tool works are given in: At the heart of the method is a discrete global grid that divides the world up into small areas of the same size.

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

open access: yesAdvanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

Synergistic Interfacial Regulation by Nano‐TiO2 and Carboxylated Cellulose Nanofibers for Multiscale Surface Stabilization of Cementitious Composites

open access: yesAdvanced Materials Technologies, EarlyView.
Nano‐TiO2 and carboxylated cellulose nanofibers jointly regulate hydration‐product distribution in cementitious composites. Improved microstructural continuity and refined pore structure accompany enhanced strength and surface stability without a substantial increase in overall hydration.

Hexagonal Discrete Global Grid Systems in Topographical and Hydrological Modeling

open access: yes, 2023
Geographic Information Systems (GIS) have dominated geospatial analysis since the 1960s, where spatial phenomena were normally represented by individual thematic layers at a specific resolution, and commonly projected to a two-dimensional Cartesian coordinate system for analysis.

Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

open access: yesAdvanced Optical Materials, EarlyView.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Using Discrete Global Grid Systems in the Pangeo ecosystem

open access: yes
Over the past few years, Discrete Global Grid Systems (DGGS) that subdivide the earth into (roughly) equally sized faces have seen a rise in popularity. However, their in-memory representation is different from traditional projection-based data, which is either comprised of evenly shaped rectangular grid (aka raster) or discrete geometries (aka vector),

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Small-signal stability analysis of a PMSG grid-connected system considering grid-forming energy storage

open access: yesZhejiang dianli
In large-scale grid-connected systems of permanent magnet synchronous generator (PMSG) wind farms, grid-forming energy storage (GFMES) can provide virtual inertia to enhance grid stability; however, it also makes accurate assessment of small-signal ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
