Abstract Neuroimaging studies have found both semantic and non-semantic effects in the default mode network (DMN), leading to an intense debate on the role of the DMN in semantic processes. Four different views have been proposed: 1) The general semantic view holds that the DMN contains several hub regions supporting general semantic processes; 2) the non-semantic view holds that the semantic effects observed in most regions of the DMN (especially the ventral angular gyrus) are confounded by difficulty and do not reflect semantic processing per se; 3) the multifunction view holds that the same areas in the DMN can support both semantic and non-semantic functions; and 4) the multisystem view holds that the DMN contains multiple subnetworks supporting different aspects of semantic processes separately. Using an fMRI experiment, we found that in one of the subnetworks of the DMN, called the social semantic network, all areas showed social semantic activation and difficulty-induced deactivation. The ventral angular gyrus, whose function had been interpreted according to the difficulty effect, showed social semantic activation independent of difficulty. In addition, the distributions of two non-semantic effects, that is, difficulty-induced and task-induced deactivations, showed dissociation in the DMN. Our findings provide two insights into the semantic and non-semantic functions of the DMN, which are consistent with both the multisystem and multifunction views: First, the same areas of the DMN can support both social semantic and non-semantic functions; second, similar to the multiple semantic effects of the DMN, the non-semantic effects also vary across its subsystems.

AbstractAn influential view in (philosophy of) cognitive science is that computation in cognitive systems is semantic, conceptually depending on representation: to compute is to manipulate representations. I argue that accepting the non-semantic teleomechanistic view of computation lays the ground for a promising alternative strategy, in which computation helps to explain and naturalise representation, rather than the other way around. I show that this computation-based approach to representation presents six decisive advantages over the semantic view. I claim that it can improve the two most influential current theories of representation, teleosemantics and structural representation, by providing them with precious tools to tackle some of their main shortcomings. In addition, the computation-based approach opens up interesting new theoretical paths for the project of naturalising representation, in which teleology plays a role in individuating computations, but not representations.

3D city models and their browser-based applications have become an increasingly applied tool in the cities. One of their applications is the analysis views and visibility, applicable to property valuation and evaluation of urban green infrastructure. We present a near real-time semantic view analysis relying on a 3D city model, implemented in a web browser. The analysis is tested in two alternative use cases: property valuation and evaluation of the urban green infrastructure. The results describe the elements visible from a given location, and can also be applied to object type specific analysis, such as green view index estimation, with the main benefit being the freedom of choosing the point-of-view obtained with the 3D model. Several promising development directions can be identified based on the current implementation and experiment results, including the integration of the semantic view analysis with virtual reality immersive visualization or 3D city model application development platforms.

NoC is a competent communication for on chip network architectures. It make more efficient the computational and high congestion communication on a single chip. In this paper, we are proposing a NoC topologies, i.e., Major Diagonal Mesh NoC called MD-Mesh NoC. In MD-Mesh NoC the corner of major diagonal linked with each other so that the efficiency of the communication among the corner can be increase. The internal semantic view and register transfer logic (RTL) View has been shown. As number of connections among the nodes increases and number of hopes decreases, performance of packet traversing will get increases. The synthesis and simulation has been done on Vertex 5 FPGA. The hardware parameters like number of slices and memory usage with respect to increase the number of nodes has been calculated on FPGA Vertex 5.

Theories are among the main achievements of scientific inquiry and appear as the repositories of scientific knowledge. This chapter is devoted to an examination of the notion of theory as a unit of analysis for the study of scientific knowledge. Most of the analysis consists in presenting and criticizing two major proposals made by philosophers of science, the “received view,” commonly attributed to logical empiricism, and the “semantic view of theories,” which became the new orthodoxy in the 1960s. Both proposals aim at formal reconstructions of theories. The shared assumptions underlying this common project will be questioned. Alternative ways of construing scientific theorizing will be sketched, notably those which are more “agent-centered” and put forward the way scientists use and understand their theories in practice.

AbstractIt has recently been suggested that meta-normative expressivism is best seen as a meta-semantic, rather than a semantic view. One strong motivation for this is that expressivism becomes, thereby, compatible with truth-conditional semantics. While this approach is promising, however, many of its details are still unexplored. One issue that still needs to be explored in particular, is what accounts of propositional contents are open to meta-semantic expressivists. This paper makes progress on this issue by developing an expressivist-friendly deflationary account of such contents.
