Non Equilibrium

Systems of “living” polymers are ubiquitous in industry and are traditionally realised using surfactants. Here I review the state-of-the-art of living polymers and discuss non-equilibrium extensions that may be realised with advanced synthetic chemistry or DNA functionalised by proteins. These systems are not only interesting in order to realise novel “living” soft matter but can also shed insight into how genomes are (topologically) regulated in vivo.

A Performance

Blockchain naturally fits multiple industry sectors due its characteristics of decentralization, enhanced security, tamper-proof, improved traceability and transparency. However, there is a significant concern of blockchain’s performance, since blockchain trades off its performance for a completely distributed feature, which enhances its security. In this paper, we investigate the state-of-the-art progress of blockchain, mainly from a performance and security perspective. We extracted 42 primary papers from major scientific databases and 34 online technical articles. The objective is to understand the current research trends, challenges and future directions. We briefly introduce the key technologies of blockchain including distributed ledger, cryptography, consensus, smart contracts and benchmarks. We next summarize the performance and security concerns raised in the investigation. We discuss the architectural choices, performance metrics, database management enhancements, and hybrid blockchains, and try to identify the effort that the state-of-the-art has made to balance between the performance and security. We also make experiments on Ethereum and survey other popular blockchain platforms on the scalability feature of blockchain. We later discuss the potential applications and present the lessons learned. Finally, we attempt to identify the open issues and possible research directions.

Salt Formation

Abstract Drilling though salt is not a new challenge in the petroleum industry, with successful exploration and appraisal wells in salt environments paving the way for complex field developments. A detailed summary of how these advancements have subsequently evolved into the technology and methods being used today is presented. The numerous challenges, and the resulting solutions, of drilling in salt environments are well documented; a comprehensive review of the relevant published industry literature has been conducted. Additionally, workshops with several major service vendors have been held to ascertain the current status of research and new product development. These two areas form the foundation of this work and have been weaved together and presented to establish what is the state of the art in salt drilling. Since the first salt wells were drilled, the drilling industry has changed considerably. Significant advancements in salt drilling technologies and methods have been made in areas such as: best drilling practices, salt formation geomechanics, salt formation geochemistry, drilling fluids, well cementing, directional drilling, drill string and drill bit design. These advancements have all been clearly delineated in a chronology of continuous improvement, compounded by the considerable weight of industry experience and lessons learned which has in turn led to optimisation, and increased efficiency, of salt drilling operations. Today, salt drilling is prevalent in areas such as the Gulf of Mexico, deep-water offshore Brazil, and deep-water West Africa, where the boundaries are continually pushed due to the perseverance of both petroleum operating companies and service vendors. The existing body of literature on salt wells is large and covers many disciplines of the upstream business, from wildcat exploration through to production. However, this focus is solely on drilling, combining and summarising many years’ worth of experience, learning, research, and development, to present what is the state of the art in salt drilling.

Molecular Skeleton

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
