TL;DR: In this paper, a formal account of how to determine the discourse relations between propositions introduced in a text and the relations between the events they describe is presented, and the distinct natural interpretations of texts with similar syntax are explained in terms of defeasible rules.
Abstract: This paper presents a formal account of how to determine the discourse relations between propositions introduced in a text, and the relations between the events they describe. The distinct natural interpretations of texts with similar syntax are explained in terms of defeasible rules. These characterise the effects of causal knowledge and knowledge of language use on interpretation. Patterns of defeasible entailment that are supported by the logic in which the theory is expressed are shown to underly temporal interpretation.

TL;DR: In this paper, the Lagrangian multiplier method is used for the computation of equilibrium states and the overall properties of discretized microstructures, where the overall macroscopic deformation is controlled by three boundary conditions: linear displacements, constant tractions and periodic displacements.
Abstract: The paper investigates algorithms for the computation of homogenized stresses and overall tangent moduli of microstructures undergoing small strains. Typically, these microstructures define representative volumes of nonlinear heterogeneous materials such as inelastic composites, polycrystalline aggregates or particle assemblies. We consider a priori given discretized microstructures, without focusing on details of specific discretization techniques in space and time. The key contribution of the paper is the construction of a family of algorithms and matrix representations of the overall properties of discretized microstructures. It is shown that the overall stresses and tangent moduli of a typical microstructure may exclusively be defined in terms of discrete forces and stiffness properties on the boundary. We focus on deformation-driven microstructures, where the overall macroscopic deformation is controlled. In this context, three classical types of boundary conditions are investigated: (i) linear displacements, (ii) constant tractions and (iii) periodic displacements and antiperiodic tractions. Incorporated by the Lagrangian multiplier method, these constraints generate three classes of algorithms for the computation of equilibrium states and the overall properties of microstructures. The proposed algorithms and matrix representations of the overall properties are formally independent of the interior spatial structure and the local constitutive response of the microstructure and are therefore applicable to a broad class of model problems. We demonstrate their performance for some representative model problems including elastic–plastic deformations of composite materials.

TL;DR: In this article, the effects of electric fields on the optical transitions of excited Rydberg states are exploited to probe very weak microwave electric fields with atoms, which can be used as highly sensitive magnetic-field sensors.
Abstract: Atoms can be used as highly sensitive magnetic-field sensors. By exploiting the effects of electric fields on the optical transitions of excited Rydberg states, it is now demonstrated that it is also possible to probe very weak microwave electric fields with atoms.

TL;DR: A switchable perfect absorber with multispectral thermal imaging capability and utilizing the amorphous-to-crystalline phase transition in GST offers switchable absorption with strong reflectance contrast at resonance and large phase-change-induced spectral shifts.
Abstract: A switchable perfect absorber with multispectral thermal imaging capability is presented. Aluminum nanoantenna arrays above a germanium antimony telluride (GST) spacer layer and aluminum mirror provide efficient wavelength-tunable absorption in the mid-infrared. Utilizing the amorphous-to-crystalline phase transition in GST, this device offers switchable absorption with strong reflectance contrast at resonance and large phase-change-induced spectral shifts.

TL;DR: Two methods for data collection in urban environments are presented and the first combines multispectral imagery and laser altimeter data in an integrated classification for the extraction of buildings, trees and grass-covered areas.
Abstract: In this article, two methods for data collection in urban environments are presented. The first method combines multispectral imagery and laser altimeter data in an integrated classification for the extraction of buildings, trees and grass-covered areas. The second approach uses laser data and 2D ground plan information to obtain 3D reconstructions of buildings.
