Advanced Science, EarlyView.Assessing species' vulnerabilities across geographical gradients is essential for biodiversity conservation under climate change. To address this challenge, the semi‐natural climate chamber across latitudes (SCCAL) is developed, a validated system capable of simulating thermal environments for ecological experiments without reliance on water or ...

Coronary angiography of the ex‐situ beating donor heart in a portable organ care system
Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1252-1260, December 1, 2022., 2022 Abstract Objectives To determine safety and feasibility of ex‐situ coronary angiography. Background To cater for the perpetually growing demand for heart donors, interest in donation following circulatory death (DCD) has been rekindled. Further pursuit of donor pool expansion has led to eligibility extension to “marginal” donors who are at higher risk ...

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.

Transcriptomic Analysis of the Spider Venom Gland Reveals Venom Diversity and Species Consanguinity
Toxins, 2019 Selenocosmia jiafu (S. jiafu) has been recently identified as a new species of spider in China. It lives in the same habitat as various other venomous spiders, including Chilobrachys jingzhao (C. jingzhao), Selenocosmia huwena (S. huwena), and Macrothele

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.

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.
