Some living beings both on ground and in water can move by forming traveling waves along their bodies, therefore the mechanisms using the traveling waves have the amphibious possibility . Several robots have been developed using the mechanisms, but there are no amphibious robots . In this study, our goal is development of a bio-mimetic soft cord robot which can move on ground and in water. Firs...

In recent years, much research has been devoted to the synthesis of link-level acknowledgements; however, few have analyzed the synthesis of checksums. After years of essential research into von Neumann machines, we show the analysis of symmetric encryption, which embodies the intuitive principles of cryptoanalysis. In order to fulfill this intent, we disconfirm that despite the fact that IPv6 ...

Tetrapods include the only fully terrestrial vertebrates, but they also include many amphibious, aquatic and flying groups. They occupy the highest levels of the food chain on land and in aquatic environments. Tetrapod evolution has generated great interest, but the earliest phases of their history are poorly understood. Recent studies have questioned long-accepted hypotheses about the origin o...

We investigate dynamical tunneling in many-dimensional systems using a quasiperiodically modulated kicked rotor, and find that the tunneling rate from the torus to the chaotic region is drastically enhanced when the chaotic states become delocalized as a result of the Anderson transition. This result strongly suggests that amphibious states, which were discovered for a one-dimensional kicked ro...

SCHMIDT-NIELSEN, BODIL, AND ERIK SKADHAUGE, Function of the excretory system of the crocodile (Crocodylus acutus) Am. ,T. Physiol. 212(5): 973-980. I 967 .-Glomerular filtration rate (GFR), tubular and cloaca1 functions were studied, during normal conditions, water loading, salt loading, and isosmotic expansion of the extracellular fluid volume. Na+, K+, Cl-, NH& and osmolality were determined ...

This essay argues that Charles Darwin's distinctive approach to studying distribution and diversity was shaped by his face-to-face interactions with maritime surveyors during the voyage of H.M.S. Beagle (1831-1836). Introducing their hydrographic surveying methods into natural history enabled him to compare fossil and living marine organisms, to compare sedimentary rocks to present-day marine s...

Ringed seals (Pusa hispida) are semi-aquatic marine mammals with a circumpolar Arctic distribution. In this study, we investigate the amphibious hearing capabilities of ringed seals to provide auditory profiles for this species across the full range of hearing. Using psychophysical methods with two trained ringed seals, detection thresholds for narrowband signals were measured under quiet, care...
