Rainfall and Temperature Explain Colony Variation in Echolocation Calls of the Intermediate Horseshoe Bats (<i>Rhinolophus affinis</i>). [PDF]
Ecol EvolWe investigated how environmental factors and body size drive colony‐level variation in echolocation calls of Rhinolophus affinis at a landscape level. Our analyses revealed a positive correlation between monthly mean precipitation and peak frequency of echolocation calls in males.

Counter operation in nonlinear micro-electro-mechanical resonators [PDF]
, 2013 This paper discusses a logical operation of multi-memories that consist of coupled nonlinear micro-electro-mechanical systems (MEMS) resonators. A MEMS resonator shows two coexisting stable states when nonlinear responses appear.

'What Does the Anemonefish Say?': Investigating <i>Amphiprion percula</i>'s Acoustic Behaviour. [PDF]
Ecol EvolThis study investigates the vocal behaviour of wild Amphiprion percula in Papua New Guinea, revealing that distinct acoustic signals correspond to specific social interactions and are influenced by behaviour and rank. The findings underscore the importance of in situ research for understanding fish communication and highlight potential disruptions from

Electrical engineering & Electromechanics, 2018 Purpose. A high-voltage underwater electric explosion, realized by discharging a capacitor into a water gap, is characterized by three main stages: the stage of formation of the plasma channel, the channel stage and post-discharge one. Substantially, the
