The trace reconstruction problem for spider graphs [PDF]
Discrete Mathematics, 346(1), 113115 (2022), 2022 We study the trace reconstruction problem for spider graphs. Let $n$ be the number of nodes of a spider and $d$ be the length of each leg, and suppose that we are given independent traces of the spider from a deletion channel in which each non-root node is deleted with probability $q$. This is a natural generalization of the string trace reconstruction

Brown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
Toxins, 2011 Venomous animals use their venoms as tools for defense or predation. These venoms are complex mixtures, mainly enriched of proteic toxins or peptides with several, and different, biological activities.

Watch out Venomous Snake Species: A Solution to SnakeCLEF2023 [PDF]
arXiv, 2023 The SnakeCLEF2023 competition aims to the development of advanced algorithms for snake species identification through the analysis of images and accompanying metadata. This paper presents a method leveraging utilization of both images and metadata. Modern CNN models and strong data augmentation are utilized to learn better representation of images.

The electronic structure and dipole moment of charybdotoxin, a scorpion venom peptide with K+ channel blocking activity [PDF]
Computational and Theoretical Chemistry 963 (2011) 384-393, 2010 The electronic structure of charybdotoxin (ChTX), a scorpion venom peptide that is known to act as a potassium channel blocker, is investigated with the aid of quantum mechanical calculations. The dipole moment vector (145 D) of ChTX can be stirred by the full length KcsA potassium channel's macrodipole (403 D) thereby assuming the proper orientation ...

Revealing the Venomous Secrets of the Spider’s Web
Journal of Proteome Research, 2020 Orb-weaving spiders use a highly strong, sticky and elastic web to catch their prey. These web properties alone would be enough for the entrapment of prey; however, these spiders may be hiding venomous secrets in the web, which current research is revealing. Here, we provide strong proteotranscriptomic evidence for the presence of toxin/neurotoxin-like

Molecular Spiders on the Plane [PDF]
Phys. Rev. E 85, 061927 (2012), 2012 Synthetic bio-molecular spiders with "legs" made of single-stranded segments of DNA can move on a surface covered by single-stranded segments of DNA called substrates when the substrate DNA is complementary to the leg DNA. If the motion of a spider does not affect the substrates, the spider behaves asymptotically as a random walk.

Spider Venoms: Biochemical Aspects [PDF]
American Zoologist, 1969 SYNOPSIS. The venoms of spiders are quite complex and contain an array of biologically active components. The majority of studies on the biochemical aspects of these venoms have utilized four species: Phoneutria fera, Lycosa erythrognatha, Atrax robustus , and Latrodectus mactans .
