Prey specificity of predatory venoms
Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

Study on lightning overvoltage and commutation failure in UHV AC/DC hybrid system
The Journal of Engineering, 2019 Due to the high UHV AC/DC transmission line tower, the working voltage amplitude on the wire is large, causing lightning accidents. The paper first analyses the impact of lightning strike point on lightning overvoltage of 1000 kV UHV transformer ...

About Geometry and Initial Phase of Cloud-to-Ground Lightning [PDF]
arXiv, 2016 Cloud-to-ground lightning is the most common among atmospheric discharges. Since electric fields in the vicinity of a thunder-cloud do not exceed 250 kV/m the physical process that triggers the lightning remains unexplained. [1, 2, 3] Recent measurements established a weak correlation between solar wind and incidence of lightning.

New York State Climate Impacts Assessment Chapter 06: Energy
Annals of the New York Academy of Sciences, Volume 1542, Issue 1, Page 341-384, December 2024.Abstract Energy plays an integral role in New Yorkers’ lives. It powers the economy, moves people and goods, keeps homes and workplaces at a livable temperature, and runs critical infrastructure that keeps people healthy and safe. Reliable energy systems are easy to take for granted, but many aspects of these systems are vulnerable to weather and ...

Analysis of Conditions favorable for Ball Lightning Creation [PDF]
arXiv, 2016 This report uses a few well documented cases of Ball Lightning (or BL for short) observations to demonstrate a correlation between BL and positive lightning, especially strong positive lightning. This allows to draw conclusions and predictions about future BL observations and the pro- duction of these objects in the laboratory. Contrary to many current

Development of Lightning Simulator [PDF]
arXiv, 2014 In this work we have developed a lightning simulator. Reproducing the light of lightning, we adopted seven waveforms that contains two light waveforms and five current waveforms of lightning. Furthermore, the lightning simulator can calibrate the color of the simulated light output based on a correlated color temperature (CCT). The CCT of the simulated
