We review theoretical and simulational approaches to the description of equilibrium bulk crystal and interface properties as well as to the nonequilibrium processes of homogeneous and heterogeneous crystal nucleation for the simple model systems of hard spheres and Lennard–Jones particles. For the equilibrium properties of bulk and interfaces, density functional theories employing fundamental measure functionals prove to be a precise and versatile tool, as exemplified with a closer analysis of the hard sphere crystal–liquid interface. A detailed understanding of the dynamic process of nucleation in these model systems nevertheless still relies on simulational approaches. We review bulk nucleation and nucleation at structured walls and examine in closer detail the influence of walls with variable strength on nucleation in the Lennard–Jones fluid. We find that a planar crystalline substrate induces the growth of a crystalline film for a large range of lattice spacings and interaction potentials. Only a strongly incommensurate substrate and a very weakly attractive substrate [less ▲]

The principle of solidarity plays a key role in discussions of social, economic, and political issues. A polysemic notion, it may interrogate either individuals or public authorities. It often represents the counterpart of competition in the analysis and assessment of social norms and public policies. [less ▲]

Solution 9: The Great Pyramid is the first in the forthcoming Solution series where authors will be asked to develop an abundance of compact and original ideas for other countries and regions, contradicting the widely held assumption that, after the end of socialism, human advancement is only possible technologically or requires a yet-to-be-established world order. This book also documents the architectural proposals for the Great Pyramid, selected by a jury composed of Rem Koolhaas, Omar Akbar, Stefano Boeri, and Miuccia Prada. It also contains critical texts and voices from the press on this exceptional project. [less ▲]

A Solution in Search of a Problem : A Method for the Development of Blockchain Use Cases

Blockchain technology is a very recent and fast evolving phenomenon with the potential to disrupt various industries. Organizations are thus increasingly looking at the technology and are forming multi-functional teams to evaluate the technology and its impact on their businesses. However, researchers and practitioners still lack a technology-driven, systematic approach to understand the potential of blockchain and to develop convincing use cases. We address this research gap by applying an action design research approach and situational method engineering to propose a method for the development of blockchain use cases. Following this approach, we iteratively evaluated and further developed the proposed method through application and testing in four distinct industries. We thus derive constructive knowledge at the cutting edge of digital transformation, innovation management, and utilization of emerging technologies. In addition, our research supports practitioners in systematically developing blockchain use cases. [less ▲]

A numerical solution of the linear and nonlinear time-dependent Schrödinger equation is obtained, using the strong form MLPG Collocation method. Schrödinger equation is replaced by a system of coupled partial differential equa tions in terms of particle density and velocity potential, by separating the real and imaginary parts of a general solution, called a quantum hydrodynamic (QHD) equa tion, which is formally analogous to the equations of irrotational motion in a classical fluid. The approximation of the field variables is obtained with the Moving Least Squares (MLS) approximation and the implicit Crank-Nicolson scheme is used for time discretization. For the two-dimensional nonlinear Schrödinger equation, the lagging of coefficients method has been utilized to eliminate the non-linearity of the corresponding examined problem. A Type-I nodal distribution is used in order to provide convergence for the discrete Laplacian operator used at the governing equation. Numerical results are validated, comparing them with analyti cal and numerical solutions. [less ▲]

Interest in blockchain is growing rapidly and at a global scale. The potential to disrupt various industries is attributed to the emerging blockchain technology. Organizations and institutions have thus begun to examine the emerging the technology and its impact on their businesses. However, researchers and practitioners still lack a systematic approach to understand the po-tential of blockchain and to develop convincing use cases. We addressed this research gap by applying an action design research approach and situational method engineering to propose a method for the development of blockchain technology use cases. Following this approach, we iteratively evaluate and further develop the proposed method through application in four distinct industries. In a next research step, we now focus on a broader context and evaluate if our existing use case development method is applicable for other emerging technologies than blockchain. By doing so, we seek to broaden our evaluation, generalize our method, and support practitioners and researchers in better leveraging the opportunities of continuous digital transformation. [less ▲]
