American Zoologist, 1969 After the spider, Zygiella x-notata Cl. has been enticed to leave the retreat and catch a fly in a web turned upside-down, it takes a relatively long time to return to the retreat. The return-time is divided into periods of active searching and motionlessness.

One Dimensional Metal Oxide Semiconductor Nanotransistors
Advanced Materials Technologies, EarlyView.This review assesses one dimensional metal oxide NW‐FETs as promising alternatives to conventional transistors. It explores how advances in architecture, material composition, and fabrication processes expand device capabilities. Emphasis is placed on novel gate configurations, different metal oxide nanowires, and post‐treatment methods, which ...

, 2015 If G is a finite graph, then the largest eigenvalue L of the adjacency matrix of G is a totally real algebraic integer (L is the Perron-Frobenius eigenvalue of G). We say that G is abelian if the field generated by L^2 is abelian.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Ground-living spiders (Araneae) at polluted sites in the Subarctic [PDF]
, 2011 Spiders were studied around the Pechenganikel smelter combine, Kola Peninsula, north-western Russia. The average spider density was 6-fold greater and the density of Linyphiidae specimens 11.5-fold higher at slightly polluted sites, compared with heavily

Fish predation by semi-aquatic spiders: a global pattern.
PLoS ONE, 2014 More than 80 incidences of fish predation by semi-aquatic spiders--observed at the fringes of shallow freshwater streams, rivers, lakes, ponds, swamps, and fens--are reviewed.
