The aim of this study was to examine how a daytime nap affected the consolidation of fear learning. Participants first underwent fear conditioning during which they were exposed to a large and a small circle. One of these was repeatedly paired with an electric shock (making it the CS+), whereas the other circle was never paired with the shock (the CS−). After a delay interval containing either a n
(Matrix presented) A combinatorial scaffolding procedure for the synthesis and spatial arrangement of tripartite structures was developed.
Aim: To describe the experience of distress in people with cancer of working age. Design: A cross-sectional study. Methods: In this cross-sectional study, patients (N = 168) with both ongoing (N = 56) and completed treatment (N = 105) completed the Distress Thermometer and the detailed problem list. Data were analysed by descriptive and analytical statistics. Results: A large proportion of patient
An investigation into the design of neural network controlled autonomous agents that navigate in uncertain environments using pre-existing visual landmarks.
This paper presents an invariant formulation and analysis of the Agent-action-Objective (AaO) kinematics in terms of David Hestenes theory of rotational dynamics. Accordingly, the term invariant refers to a coordinate-free establishment of structure. Its major aim is to make evident that Natural Language employs its own intrinsic systems of coordinates, but these are generally unknown. In particul
Claims have been made that Botswana's last four decades of success with economic growth and political stability builds on a foundation of good political institutions. In this paper these political institutions are critically analysed.
Parallel robots are generally said to be more accurate but to have a smaller workspace compared to serial robots. With the Gantry-Tau robot, a parallel robot with a large, reconfigurable workspace was presented. This article tries to identify the maximum achievable end-effector positioning accuracy of the Gantry-Tau robot. To this end, a couple of new kinematic error models are presented and evalu
This paper presents low power hardware generation, based on a CAL actor language dataflow implementation. The CAL language gives a higher level of abstraction and generate both hardware and software description. The original CAL flow is targeted for hardware-software co-design of complex systems on FPGA. Modifications are done to the original CAL flow to facilitate low power ASIC implementations.
We study the Al-Salam-Chihara polynomials when q > 1. Several solutions of the associated moment problem are found, and the orthogonality relations lead to explicit evaluations of several integrals. The polynomials are shown to have raising and lowering operators and a second order operator equation of Sturm-Liouville type whose eigenvalues are found explicitly. We also derive new measures with re
Existing bridges were designed to satisfy old specifications, and most of them were based on a member-oriented approach. A bridge superstructure is constituted by a group of elements that together form a system, and depending on how robust the system is, a member-oriented approach losses accuracy. Therefore, in this study a preliminary framework of how to assess concrete bridges' robustness is pre
