The book explores dynamic interactions between soil and foundation structures, addressing both seismic and traffic-induced vibration issues. It presents findings that lead to the development of performance-based design countermeasures aimed at safeguarding foundations from severe earthquakes and mitigating vibrations that disturb nearby residents and manufacturers.

This volume brings together a multidisciplinary group of scholars from diverse fields including computer science, engineering, archival science, law, business, psychology, economics, medicine and more to discuss the trade-offs between different “layers” in designing the use of blockchain/Distributed Ledger Technology (DLT) for social trust, trust in data and records, and trust in systems. Blockchain technology has emerged as a solution to the problem of trust in data and records, as well as trust in social, political and economic institutions, due to its profound potential as a digital trust infrastructure. Blockchain is a DLT in which confirmed and validated sets of transactions are stored in blocks that are chained together to make tampering more difficult and render records immutable. This book is dedicated to exploring and disseminating the latest findings on the relationships between socio-political and economic data, record-keeping, and technical aspects of blockchain. 

This book systematically reviews recent advances in the synthetic methods and applications of helicenes. The first part of this book introduces the nomenclature and structural features of helicenes. The second part reviews several classic and useful methods as well as recently-developed approaches for the preparation and functionalization of helicenes, including photocyclization and Diels-Alder reactions, which are two important breakthroughs in the syntheses of helicenes. In the last part, the applications of helicenes in asymmetric syntheses, molecular machines, molecular recognition, self-assembly and other fields are discussed. This book provides a useful reference source for researchers and graduate students working not only in the area of helicene chemistry, but also in other research areas including materials science, supramolecular chemistry, coordination chemistry, and physical organic chemistry. Chuan-Feng Chen is a Professor at the Institute of Chemistry, Chinese Academy of Sciences, China.

To understand the corona's buildup during active region formation via magnetic flux emergence in the photosphere, we utilize a magnetic flux emergence simulation to drive a magnetohydrodynamics (MHD) simulation for the corona. By properly addressing energy balance, akin to the real corona, our model synthesizes EUV emission that aligns with observations. During the formation of a sunspot pair in the model photosphere, numerous bright coronal EUV loops emerge, rooted at the sunspots' outer edges, where enhanced upward Poynting flux results from the interaction of flows and magnetic field structures. The thermal dynamics and energetics of plasma along individual magnetic field lines align with traditional one-dimensional loop models with prescribed heat input. Although EUV loops are positioned along magnetic field lines at any given time, their temporal evolution can vary significantly. As the footpoints of emerging magnetic field lines traverse regions of increased energy input at the sunspot's edge, a seemingly static EUV structure forms from the plasma in these emerging lines. This model underscores the effectiveness of realistic three-dimensional simulations in replicating features of the actual corona and highlights the critical need to concurrently treat plasma and magnetic fields to accurately model coronal plasma dynamics.

Iptycenes From Synthesis to Applications provides a comprehensive overview of the development of iptycene chemistry in the past seventy years. This book (1) the basic nomenclature and general properties of iptycenes and their derivatives; (2) the synthesis and functionalization reactions of triptycenes, pentiptycenes, higher iptycenes, heterotriptycenes, and homotriptycenes; (3) the methods for the preparation of iptycene-based polymers with different types; and (4) the applications of iptycenes and their derivatives in molecular machines, materials science, host-guest chemistry, self-assembly, coordination chemistry, physical organic chemistry, medicinal chemistry, and so on. Consequently, such a book is not only helpful to researchers working in iptycene chemistry, but can also facilitate future research in wide areas.
