A Completeness Study on Certain 2×22\times2 Lax Pairs Including Zero Terms

We expand the completeness study instigated in [J. Math. Phys. 50 (2009), 103516, 29 pages] which found all $2\times2$ Lax pairs with non-zero, separable terms in each entry of each Lax matrix, along with the most general nonlinear systems that can be associated with them. Here we allow some of the terms within the Lax matrices to be zero. We cover all possible Lax pairs of this type and find a new third order equation that can be reduced to special cases of the non-autonomous lattice KdV and lattice modified KdV equations among others

Simulations of Solid-on-Solid Models of Spreading of Viscous Droplets

We have studied the dynamics of spreading of viscous non-volatile fluids on surfaces by MC simulations of SOS models. We have concentrated on the complete wetting regime, with surface diffusion barriers neglected for simplicity. First, we have performed simulations for the standard SOS model. Formation of a single precursor layer, and a density profile with a spherical cap shaped center surrounded by Gaussian tails can be reproduced with this model. Dynamical layering (DL), however, only occurs with a very strongly attractive van der Waals type of substrate potential. To more realistically describe the spreading of viscous liquid droplets, we introduce a modified SOS model. In the new model, tendency for DL and the effect of the surface potential are in part embedded into the dynamics of the model. This allows a relatively simple description of the spreading under different conditions, with a temperature like parameter which strongly influences the droplet morphologies. Both rounded droplet shapes and DL can easily be reproduced with the model. Furthermore, the precursor width increases proportional to the square root of time, in accordance with experimental observations.

Process tracing: a laudable aim or a high-tariff methodology?

It was with considerable pleasure and enthusiasm that I accepted the invitation of Christine Trampusch and Bruno Palier, the editors of this special issue, to respond to their small but excellent collection of papers on process tracing in political economy. Like them (Trampusch and Palier 2016), I am convinced that what they and others typically call process tracing can, if appropriately (and, indeed, sparingly) used, help open the black box of causation in social, political and economy systems; it can, in short, help us fashion better explanations of social, political and economic outcomes. I am also convinced, like them, that the clarification of what process tracing actually entails methodologically, as is the principal aim of this special issue, will help us better make that case. In the, alas, all too limited space I have, I cannot and hence do not seek to provide a detailed commentary and reflection on each of the papers in this collection. Instead, I will keep my comments very general – using, as my point of departure, the editors’ very useful framing essay. I will confine myself to three appreciative, though at the same time critical yet I hope constructive, observations in the hope of advancing the debat

Does capitalism (still) come in varieties?

That capitalisms vary and that these capitalisms neatly resolve themselves into distinct and discrete ‘varieties of capitalism’ is an almost foundational claim of contemporary comparative political economy. Yet it is far from evident that it is true. In this article, I return to the varieties conjecture, assessing the degree to which the claim might be warranted. In the process, I argue for the importance of differentiating clearly between ideal types and real types and for the value of heeding Weber’s advice about the dangers of confusing one for the other. I suggest that although capitalisms do not really come in varieties it is sometimes useful to proceed on the basis that they do, particularly if we think of such varieties as potentially dystopic. I suggest that such an acknowledgement is crucial in sensitizing us to the potential biases of varietal thinking, drawing out the implications for the positing of capitalist varieties in the period after the global financial crisis

Labeling research in support of through-the-season area estimation

The development of LANDSAT-based through-the-season labeling procedures for corn and soybeans is discussed. A model for predicting labeling accuracy within key time periods throughout the growing season is outlined. Two methods for establishing the starting point of one key time period, viz., early season, are described. In addition, spectral-temporal characteristics for separating crops in the early season time period are discussed

Serial Position Effects in Short-term Visual Memory: A SIMPLE Explanation?

A version of Sternberg’s (1966) short-term, visual memory recognition paradigm with pictures of unfamiliar faces as stimuli was used in three experiments to assess the applicability of the distinctiveness based SIMPLE model proposed by Brown, Neath & Chater (2002). Initial simulations indicated that the amount of recency predicted increased as the parameter measuring the psychological distinctiveness of the stimulus material (c) increased, and that the amount of primacy was dependent on the extent of proactive interference from previously presented stimuli. The data from experiment 1, which used memory lists of four and five faces varying in visual similarity confirmed the predicted, extended recency effect. However, changes in visual similarity were not found to produce changes in c. In Experiments 2 and 3, the conditions that influence the magnitude of c were explored. These revealed that both the familiarity of the stimulus class before testing, and changes in familiarity due to perceptual learning, influenced distinctiveness as indexed by the parameter c. Overall the empirical data from all three experiments were well-fit by SIMPLE
