Cooperative effects enhance the transport properties of molecular spider teams [PDF]
Phys. Rev. E 87, 032706 (2013), 2013 Molecular spiders are synthetic molecular motors based on DNA nanotechnology. While natural molecular motors have evolved towards very high efficiency, it remains a major challenge to develop efficient designs for man-made molecular motors.

Giant Surface Plasmon Induced Drag Effect (SPIDEr) in Metal Nanowires [PDF]
, 2009 Here, for the first time we predict a giant surface plasmon-induced drag effect (SPIDEr), which exists under conditions of the extreme nanoplasmonic confinement.

Molecular Spiders with Memory [PDF]
Physical Review E 76, 021121 (2007), 2007 Synthetic bio-molecular spiders with "legs" made of single-stranded segments of DNA can move on a surface which is also covered by single-stranded segments of DNA complementary to the leg DNA.

Exercising Control When Confronted by a (Brownian) Spider [PDF]
arXiv, 2016 We consider the Brownian "spider," a construct introduced in \cite{Dubins} and in \cite{Pitman}. In this note, the author proves the "spider" bounds by using the dynamic programming strategy of guessing the optimal reward function and subsequently ...

A Social Spider Algorithm for Global Optimization [PDF]
arXiv, 2015 The growing complexity of real-world problems has motivated computer scientists to search for efficient problem-solving methods. Metaheuristics based on evolutionary computation and swarm intelligence are outstanding examples of nature-inspired solution techniques.

A Constraint on Primordial B-modes from the First Flight of the Spider Balloon-borne Telescope [PDF]
Astrophysical Journal, 2021 We present the first linear polarization measurements from the 2015 long-duration balloon flight of Spider, which is an experiment that is designed to map the polarization of the cosmic microwave background (CMB) on degree angular scales.

Spider Silk‐Inspired Artificial Fibers
Advancement of science, 2021 Spider silk is a natural polymeric fiber with high tensile strength, toughness, and has distinct thermal, optical, and biocompatible properties. The mechanical properties of spider silk are ascribed to its hierarchical structure, including primary and ...

Occupation Times on the Legs of a Diffusion Spider. [PDF]
Entropy (Basel)We study the joint moments of occupation times on the legs of a diffusion spider. Specifically, we give a recursive formula for the Laplace transform of the joint moments, which extends earlier results for a one-dimensional diffusion. For a Bessel spider, of which the Brownian spider is a special case, our approach yields an explicit formula for the ...
