This essay proposes that the picture of a broken circle encountered by Watt during the second part of his tale marks a crucial collision point between Beckett's literary and mathematical interests and triggers a process of fractal scaling self-similarity. Building on recent interest concerning the role of the mathematics and mathematical forms found in Beckett's work, I argue that the broken circle depicted in the picture from Watt is a geometric form which (re)appears within at least three interlocking scales throughout Beckett's novel-length prose: (i) its moment of arrival in the picture from Watt, (ii) a macroscopic reinscription in the names of the protagonists populating the five novels spanning Watt through to The Unnamable and (iii) buried within the narratological depths of How It Is. As a structural principle, the interminable irregularity of fractals offered Beckett a viable solution for what he considered the defining task of the modern artist: ‘to find a form to accommodate the mess’. Moreover, the specific shape selected for his fractal is shown to contain within its geometry one of Beckett's most universal and pressing concerns: the inevitable insufficiency of language. Therefore, although this essay restricts itself to examining Beckett's novel-length prose, the idea of a broken circle fractal promises to provide a valuable heuristic through which to reassess the author's other generic avenues. Fractals thus offer a means through which one can bind together the length and breadth of Beckett's oeuvre without ever reducing dynamic chaos to stable order.

The Introduction offers a brief overview of Paul Slack’s contribution to early modern history, distinguishing between an earlier phase concerned with social policy and the ideas which informed it, and a later phase concerned with the history of political economy, and particularly the shifting discourse of happiness which, he argued, informed it. It then explores recent interest in the history of emotions, distinguishing a variety of approaches to that subject. Reviewing three broad approaches taken by the contributors to the volume, it goes on to suggest that the history of emotions is most stimulating when seen as a focal point for different kinds of history rather than as a discrete subject of enquiry. A further implication is that a variety of forms of expertise need to be brought to bear.

There has been considerable recent interest in certain integral transform operators with non-singular kernels and their ability to be considered as fractional derivatives. Two such operators are the Caputo–Fabrizio operator and the Atangana–Baleanu operator. Here we present solutions to simple initial value problems involving these two operators and show that, apart from some special cases, the solutions have an intrinsic discontinuity at the origin. The intrinsic nature of the discontinuity in the solution raises concerns about using such operators in modelling. Solutions to initial value problems involving the traditional Caputo operator, which has a singularity inits kernel, do not have these intrinsic discontinuities.

Every year, hundreds of U.S. citizens patrol the Mexican border dressed in camouflage and armed with pistols and assault rifles. Unsanctioned by the government, these militias aim to stop the movement of narcotics into the United States. Recent interest in the anthropology of ethics has focused on how individuals cultivate themselves toward a notion of the ethical. In contrast, within the militias, ethical self-cultivation was absent. I argue the volunteers derived the power to be ethical from the control of the dominant moral assemblage and the construction of an immoral “Other” which provided them the power to define a moral landscape that limited the potential for ethical conflicts. In the article, I discuss two instances Border Watch and its volunteers dismissed disruptions to their moral certainty and confirmed to themselves that their actions were not only the “right” thing to do, but the only ethical response available.

Abstract Motivated by the recent interest in even-Clifford structures and in generalized complex and quaternionic geometries, we introduce the notion of generalized almost even-Clifford structure. We generalize the Arizmendi-Hadfield twistor space construction on even-Clifford manifolds to this setting and show that such a twistor space admits a generalized complex structure under certain conditions.

AbstractWe demonstrate how a full QM/MM derivatization of the recently developed GOCAT model can be utilized in the global optimization of molecular embeddings. To this end, we provide two distinct examples: An $$\text {S}_\text {N}2$$ S N 2 reaction, and one enzymatic example of recent interest, the ketosteroid isomerase. These serve us to highlight the advantages of such an approach and sketch the roadmap for further improvements.

AbstractWhat do Christians do when they read? How can Christian reading be understood anthropologically? Anthropologists of Christianity have offered many ethnographic descriptions of the interplay among people, words, and material objects across Christian groups, but descriptions of Christian reading have often posited an androgynous reader. In response to this we begin from the observation that while reading cannot be done without words, it also cannot be done without a body. We propose that an analytic approach of placing language and materiality (including bodies) together will help clarify that reading texts is an embodied practice, while not undermining the importance of working with words. We draw inspiration from the recent interest in bringing linguistic anthropology and materiality studies together into the same analytic frame of “language materiality.” We explore a language-materiality approach to reading by comparing how the biblical story of Mary and Martha was read by Protestant women in two historical situations: 1920s Norway and the 1950s United States. We argue that in these cases the readers’ gendered, raced, and classed bodies were central to the activity of reading texts, including their bodies’ material engagements with the world, such as carrying out women's work. We suggest that paying attention to embodied reading—that is, readers’ social entanglements with both language and materiality—yields a fuller analysis of what reading is in particular historical situations, and ultimately questions the notion of a singular Protestant semiotic ideology that works consistently toward purification.

The automated analysis of natural language data has become a central issue in the design of intelligent information systems. Processing unconstrained natural language data is still considered as an AI-hard task. However, various analysis techniques have been proposed to address specific aspects of natural language. In particular, recent interest has been focused on providing approximate analysis techniques, assuming that when perfect analysis is not possible, partial results may be still very useful.
