Squeezing millimeter waves into microns.
Microstructured metallic devices will play a vital role in the continuing search to manipulate the passage of electromagnetic radiation relevant to optical, microwave, and communication technologies. Here, we investigate the electromagnetic response of a completely novel and ultrathin (<< wavelength) structure within which is buried a metal-clad waveguiding layer ("core") of subwavelength width...
متن کاملSqueezing MOND into a Cosmological Scenario.
Explaining the effects of dark matter using modified gravitational dynamics (MOND) has for decades been both an intriguing and controversial possibility. By insisting that the gravitational interaction that accounts for the Newtonian force also drives cosmic expansion, one may kinematically identify which cosmologies are compatible with MOND, without explicit reference to the underlying theory ...
متن کاملPacking and Squeezing Subgraphs into Planar Graphs
We consider the following problem: Given a set S of graphs, each of n vertices, construct an nvertex planar graph G containing all the graphs of S as subgraphs. We distinguish the variant in which any two graphs of S are required to have disjoint edges in G (known as ’packing’) from the variant in which distinct graphs of S can share edges in G (called ’squeezing’). About the packing variant we...
متن کاملDeformable Motion: Squeezing into Cluttered Environments
We present an interactive method that allows animated characters to navigate through cluttered environments. Our characters are equipped with a variety of motion skills to clear obstacles, narrow passages, and highly constrained environment features. Our control method incorporates a behavior model into well-known, standard path planning algorithms. Our behavior model, called deformable motion,...
متن کاملSqueezing an egg into a worm: C. elegans embryonic morphogenesis.
We review key morphogenetic events that occur during Caenorhabditis elegans (www.wormbase.org/) embryogenesis. Morphogenesis transforms tissues from one shape into another through cell migrations and shape changes, often utilizing highly conserved actin-based contractile systems. Three major morphogenetic events occur during C. elegans embryogenesis: (1) dorsal intercalation, during which two r...
