Nature, 1879 THIS arachnid is very common out here, a very tiger amongst insects, and very interesting to watch. Its poison must be intensely virulent. If two are placed together under a finger bowl, and one happens to be the smaller, a very little manœuvring soon brings him within the instantaneously fatal grip of the larger animal; but if of equal size, a most ...

Advanced Science, EarlyView.The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

Self‐Assembly of Linear, Natural Antimicrobial Peptides: An Evolutionary Perspective
ChemPlusChem, Volume 87, Issue 12, December 2022., 2022 Antimicrobial peptides are an ancient defence against a wide range of microbes. Some can self‐assemble into oligomers and amyloid. Similarities with neurodegenerative diseases support a hypothesis that some diseases are due to aberrant activity of a protective neuropeptide.

SPIDER: Near-Optimal Non-Convex Optimization via Stochastic Path Integrated Differential Estimator [PDF]
arXiv, 2018 In this paper, we propose a new technique named \textit{Stochastic Path-Integrated Differential EstimatoR} (SPIDER), which can be used to track many deterministic quantities of interest with significantly reduced computational cost. We apply SPIDER to two tasks, namely the stochastic first-order and zeroth-order methods.

Advanced Science, EarlyView.Inspired by the structure of sea sponges, a unique method involving microfluidic coaxial spinning and in situ polymerization is designed. Biomimetic tubular scaffolds ae fabricated. Composed of specific materials such as oxidized bacterial cellulose, bacterial cellulose and polydopamine, these scaffolds have excellent mechanical stability and ...

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 establishing its optimality by proving its excessiveness.
