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 ▲]

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.

The alignment of a set of objects by means of transformations plays an important role in computer vision. Whilst the case for only two objects can be solved globally, when multiple objects are considered usually iterative methods are used. In practice the iterative methods perform well if the relative transformations between any pair of objects are free of noise. However, if only noisy relative transformations are available (e.g. due to missing data or wrong correspondences) the iterative methods may fail. Based on the observation that the underlying noise-free transformations lie in the null space of a matrix that can directly be obtained from pairwise alignments, this paper presents a novel method for the synchronisation of pairwise transformations such that they are globally consistent. Simulations demonstrate that for a high amount of noise, a large proportion of missing data and even for wrong correspondence assignments the method delivers encouraging results. [less ▲]

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 ▲]

Our goal in this work is to give an algorithmic method to find solutions of a LSS. To accomplish this objective, we will give a geometric description of the problem and use some geometric tools to transform the equation and the manifold (the "ambient space") into a new set of equations, each one being an explicit ODE. When this is accomplished, one may apply Picard's theorem to these new systems to obtain the solutions. It is important to notice that (as many other theoretical results) Picard's theorem proves the existence of a solution but does not give an explicit method to nd it. Usually, in problems which require to find explicit solutions, numerical methods are used. There also exist numerical methods for solving LSS, so one may think that (since we will use numerical methods anyway to find the explicit solution) we could use them directly instead of wasting time implementing a method that will still depend on numerical approximations. The main point of using alternative methods for this kind of problem is (beyond the theoretical value of the algorithm) that, while numerical methods for explicit ODEs are usually accurate (in the sense that it is easy to control the error of the calculations), numerical approximations for an arbitrary LSS require (as it is explained in [RR02]) numerical inversions of quasi-singular matrices; these operations are numerically unstable. Therefore, the desingularization procedure studied here may allow to transform a numerically unstable problem into a new stable one. [less ▲]

In this paper, we push forward the hypothesis that misalignment between expectations and aspirations crucially affects the educational outcomes of young adults. Using AddHealth, a dataset of 20,774 adolescents between the grades 7-12, we show that the difference in school performance between migrant children and natives lies within the aspirations and expectations that migrant children form. More specifically, we find that positive misalignment between aspirations and expectations is a driving force for higher effort and better education outcomes of immigrant teenagers in the USA. This force resolves the well-known immigrant paradox. Furthermore, this result is specific to migrant children and does not hold for second-generation migrant pupils. [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 ▲]

The following natural problem, first considered by D. Lau, has been tackled by several authors recently: Let C be a total clone on 2 := {0, 1}. Describe the interval I(C) of all partial clones on 2 whose total component is C. We establish some results in this direction and combine them with previous ones to show the following dichotomy result: For every total clone C on 2, the set I(C) is either finite or of continuum cardinality.

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 ▲]
