This book is the fifth volume of the proceedings of the 4th GeoShanghai International Conference that was held on May 27 - 30, 2018. This volume, entitled “Tunneling and Underground Construction”, covers the recent advances and technologies in tunneling and underground structure engineering. It presents the state-of-the-art planning philosophy, theories, experiments, methodologies and findings in the related areas. The importance of underground space utilization to the development of human society is also addressed. The challenges and future directions of underground engineering are highlighted. The topics include but are not limited to the tunneling and underground construction induced ground deformation, mechanical behaviors of segmental lining systems, tunneling in challenging situations, maintenance tactic and emergency counter-measures. The book may benefit researchers and scientists from the academic fields of tunneling and underground structure engineering as well as practical engineers from the industry.Each of the papers included in this book received at least two positive peer reviews. The editors would like to express their sincerest appreciation to all of the anonymous reviewers all over the world, for their diligent work.

Nuclear Quantum Effects from Bio to Physical Chemistry

Guy Noble suggests ways of keeping busy during lockdown: maybe we need al fresco orchestras?

The authors have fabricated a tunnel diode comprising a two-dimensional electron gas channel formed at an AlGaAs/GaAs heterojunction by molecular beam epitaxy and nanometre-scale oxides locally generated using an atomic force microscope (AFM). The AFM-generated oxide lines have been adopted as integral parts of the device, for the first time serving as effective tunnel barriers for single electron transport.

The phenomenon of tunneling is investigated for a symmetric double-well potential perturbed by a monochromatic driving force. The analysis is based on a numerical treatment of the quantum map that propagates the system over one period of the external force, and of the spectrum of its eigenphases (quasienergies). The variety in the quasienergy spectrum, such as exact and avoided crossings, leads to novel forms of coherent tunneling. In particular, for specific parameter values of the driving force, we find almost complete localization of the wave packet in one of the wells.

Chemists at MIT and in South Korea have demonstrated characteristics of a phenomenon called quantum tunneling by using a very large electric field to alter the ability of ammonia molecules to switch between the normal and inverted states.

Hello CommunityIs this procedure https://documentation.commvault.com/commvault/v11/article?p=129268.htm equivalent to using a network topology (network gateway for instance so that the traffic is tunneled through a single port 8403) and enabling the checkbox “encrypt network traffic” on the network...

When wiring through a While Loop or For Loop, the tunnels for the wires are either solid or have square brackets on them. What is the difference between these tunnels? How can I change them? When wiring through a While Loop or For Loop, the data type entering is different than the data type exiting. Why is this?

IP Security, or IPsec, is a framework for securely exchanging data over unprotected networks. Read about how it's used and the key steps to making it work.

Scattering is fundamental to almost everything we know about the world, such as why the sky is blue. Tunnelling is entirely quantum-mechanical and gives rise to such phenomena as nuclear fusion in...

This appendix describes how to set up a GRE Ethernet (Layer 2) tunnel to a RUEI Collector Engine and how to use a tap with this configuration.

Using quantum tunneling, the lab of Shantanu Chakrabartty, at the McKelvey School of Engineering at Washington University in St. Louis, has developed self-powered sensors that can run for more than a year.
