PLoS ONE, 2020 Cobweb weaving spiders and their relatives spin multiple task-specific fiber types. The unique material properties of each silk type result from differences in amino acid sequence and structure of their component proteins, primarily spidroins (spider ...

External DNA contamination and efficiency of bleach decontamination for arthropod diet analysis
Environmental DNA, 2023 DNA metabarcoding is increasingly used to analyze the diet of arthropods, including spiders. However, high sensitivity to DNA contamination makes it difficult to apply to organisms obtained from mass‐sampling methods such as pitfall traps. An alternative

Molecular Spiders in One Dimension [PDF]
Journal of Statistical Mechanics P08027 (2007), 2007 Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs. Different mappings are established between various models of spiders and simple exclusion processes.

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. Inspired by biological motor proteins like kinesin and myosin, molecular spiders comprise a body and several legs.

The restoration potential of offshore mussel farming on degraded seabed habitat
Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 437-449, December 2022., 2022 Due to the artificial structures that accumulate mussels and exclude destructive fishing practices, the seabed could be restored by the installation of mussel farming structure. After four years, there was a significantly greater abundance of mobile taxa compared to the Controls that remained open to trawling. Commercial European lobster and brown crab

The perturbed prox-preconditioned spider algorithm: non-asymptotic convergence bounds [PDF]
IEEE Statistical Signal Processing Workshop, Jul 2021, Rio de
Janeiro, Brazil, 2021 A novel algorithm named Perturbed Prox-Preconditioned SPIDER (3P-SPIDER) is introduced. It is a stochastic variancereduced proximal-gradient type algorithm built on Stochastic Path Integral Differential EstimatoR (SPIDER), an algorithm known to achieve near-optimal first-order oracle inequality for nonconvex and nonsmooth optimization.
