ADBR: Accelerated Depth-Based Routing for Underwater Sensor Networks

open access: yesJITCE (Journal of Information Technology and Computer Engineering), 2022
It is challenging to propose an efficient routing algorithm for Underwater Wireless Sensor Networks (UWSNs) in terms of packet delivery ratio, end-to-end delay of packet delivery from the source to the destination, and energy consumption. The reasons of

Original composition and formation process of slab-derived deep brine from Kashio mineral spring in central Japan

open access: yesEarth, Planets and Space, 2020
Brine samples from the wells in the Kashio mineral spring (an “Arima-type” hot spring at Ooshika-Mura, central Japan) were analyzed to determine the original chemical and isotopic compositions of the deep brine end-member before its dilution by meteoric ...

A theoretical study on the spatial effect of water-rich foundation pit instability failure

open access: yesAIP Advances, 2021
According to the lack of theoretical research on the spatial effect of the foundation pit, the concept of the reasonable arch curve (bending moment on the curve is zero everywhere) is introduced to establish a new three-dimensional instability failure ...

A persistent and dynamic East Greenland Ice Sheet over the past 7.5 million years [PDF]

open access: yes, 2016
Climate models show that ice-sheet melt will dominate sea-level rise over the coming centuries, but our understanding of ice-sheet variations before the last interglacial 125,000 years ago remains fragmentary.
