We present a combined gain media Kerr-lens mode-locked laser based on a Tm:Lu_2O_3
ceramic and a Tm:Sc_2O_3 single crystal. Pulses as short as 41 fs, corresponding to less …

The combination of hydraulic fracturing and depressurization method has been proposed to
enhance gas production efficiency from methane hydrate (MH) reservoirs. To evaluate the …

Understanding flow mechanisms in fractured media is essential for geoscientific research and
geological development industries. This study used 3‐D printed fracture networks in order …

We report on a high quality-factor Kerr-lens mode-locked Tm: Sc 2 O 3 laser operating around
2.1 μm. Using a simple four mirror Z-shaped cavity consisting of an output coupler (OC) of …

Hydraulic fracturing using water-based fluid consumes a large amount of freshwater resources
and pollutes a reservoir by substantially decreasing its matrix permeability. To address …

The temperature distribution at depth is a key variable when assessing the potential of a
supercritical geothermal resource as well as a conventional geothermal resource. Data-driven …

Long-Infrared camera (LIR) onboard Akatsuki have detected bow-shaped features over
mountain regions, suggesting that mountain waves propagate upward to reach the cloud top …

In order to resolve discrepancy between recent observational and numerical studies on the
thermal tides in the Venusian atmosphere, we investigated by means of a general circulation …

Topological data analysis is an emerging concept of data analysis for characterizing shapes.
A state-of-the-art tool in topological data analysis is persistent homology, which is expected …

Many natural methane hydrate (MH) reservoirs are heterogeneous and are characterized
by a layered structure. In this study, we numerically investigate gas production from a multi-…
